3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in 3GPP TR 21.905 [1] and the following
apply. A term defined in the present document takes precedence over the definition of the same term, if any, in 3GPP
TR 21.905 [1].
Elementary Procedure: NGAP consists of Elementary Procedures (EPs). An Elementary Procedure is a unit of
interaction between the NG-RAN node and the AMF. These Elementary Procedures are defined separately and are
intended to be used to build up complete sequences in a flexible manner. If the independence between some EPs is
restricted, it is described under the relevant EP description. Unless otherwise stated by the restrictions, the EPs may be
invoked independently of each other as standalone procedures, which can be active in parallel. The usage of several
NGAP EPs together or together with EPs from other interfaces is specified in stage 2 specifications (e.g., TS 38.401 [2],
TS 38.410 [3] and TS 38.300 [8]).
An EP consists of an initiating message and possibly a response message. Two kinds of EPs are used:
- Class 1: Elementary Procedures with response (success and/or failure).
- Class 2: Elementary Procedures without response.
For Class 1 EPs, the types of responses can be as follows:
Successful:
- A signalling message explicitly indicates that the elementary procedure successfully completed with the
receipt of the response.
Unsuccessful:
- A signalling message explicitly indicates that the EP failed.
- On time supervision expiry (i.e., absence of expected response).
Successful and Unsuccessful:
- One signalling message reports both successful and unsuccessful outcome for the different included requests.
The response message used is the one defined for successful outcome.
ETSI
Class 2 EPs are considered always successful.
gNB: as defined in TS 38.300 [8].
ng-eNB: as defined in TS 38.300 [8].

4.1 Procedure Specification Principles

The principle for specifying the procedure logic is to specify the functional behaviour of the terminating node exactly
and completely. Any rule that specifies the behaviour of the originating node shall be possible to be verified with
information that is visible within the system.
The following specification principles have been applied for the procedure text in clause 8:
- The procedure text discriminates between:
1) Functionality which "shall" be executed
ETSI
The procedure text indicates that the receiving node "shall" perform a certain function Y under a certain
condition. If the receiving node supports procedure X but cannot perform functionality Y requested in the
REQUEST message of a Class 1 EP, the receiving node shall respond with the message used to report
unsuccessful outcome for this procedure, containing an appropriate cause value.
2) Functionality which "shall, if supported" be executed
The procedure text indicates that the receiving node "shall, if supported," perform a certain function Y under
a certain condition. If the receiving node supports procedure X, but does not support functionality Y, the
receiving node shall proceed with the execution of the EP, possibly informing the requesting node about the
not supported functionality.
- Any required inclusion of an optional IE in a response message is explicitly indicated in the procedure text. If the
procedure text does not explicitly indicate that an optional IE shall be included in a response message, the
optional IE shall not be included. For requirements on including Criticality Diagnostics IE, see clause 10.
4.2 Forwards and Backwards Compatibility

The forwards and backwards compatibility of the protocol is assured by mechanism where all current and future
messages, and IEs or groups of related IEs, include ID and criticality fields that are coded in a standard format that will
not be changed in the future. These parts can always be decoded regardless of the standard version.
4.3 Specification Notations

For the purposes of the present document, the following notations apply:
Procedure When referring to an elementary procedure in the specification the Procedure Name is written with
the first letters in each word in upper case characters followed by the word "procedure", e.g.,
Procedure Name procedure.
Message When referring to a message in the specification the MESSAGE NAME is written with all letters
in upper case characters followed by the word "message", e.g., MESSAGE NAME message.
IE When referring to an information element (IE) in the specification the Information Element Name
is written with the first letters in each word in upper case characters and all letters in Italic font
followed by the abbreviation "IE", e.g., Information Element IE.
Value of an IE When referring to the value of an information element (IE) in the specification the "Value" is
written as it is specified in subclause 9.2 enclosed by quotation marks, e.g., "Value".
5 NGAP Services
NGAP provides the signalling service between the NG-RAN node and the AMF that is required to fulfil the NGAP
functions described in TS 38.410 [3]. NGAP services are divided into two groups:
Non UE-associated services: They are related to the whole NG interface instance between the NG-RAN node and
AMF utilising a non UE-associated signalling connection.
UE-associated services: They are related to one UE. NGAP functions that provide these services are
associated with a UE-associated signalling connection that is maintained for the UE
in question.
6 Services Expected from Signalling Transport

The signalling connection shall provide in sequence delivery of NGAP messages. NGAP shall be notified if the
signalling connection breaks.
ETSI
7 Functions of NGAP
The functions of NGAP are described in TS 38.410 [3].
8 NGAP Procedures
8.1 List of NGAP Elementary Procedures

In the following tables, all EPs are divided into Class 1 and Class 2 EPs (see subclause 3.1 for explanation of the

8.2 PDU Session Management Procedures

8.2.1 PDU Session Resource Setup
8.2.1.1 General
The purpose of the PDU Session Resource Setup procedure is to assign resources on Uu and NG-U for one or several
PDU sessions and the corresponding QoS flows, and to setup corresponding DRBs for a given UE. The procedure uses
UE-associated signalling.
ETSI
8.2.1.2 Successful Operation
Figure 8.2.1.2-1: PDU session resource setup: successful operation
The AMF initiates the procedure by sending a PDU SESSION RESOURCE SETUP REQUEST message to the NG-
RAN node.
The PDU SESSION RESOURCE SETUP REQUEST message shall contain the information required by the NG-RAN
node to setup the PDU session related NG-RAN configuration consisting of at least one PDU session resource and
include each PDU session resource to setup in the PDU Session Resource Setup Request List IE.
Upon reception of the PDU SESSION RESOURCE SETUP REQUEST message, if resources are available for the
requested configuration, the NG-RAN node shall execute the requested NG-RAN configuration and allocate associated
resources over NG and over Uu for each PDU session listed in the PDU Session Resource Setup Request List IE.
If the RAN Paging Priority IE is included in the PDU SESSION RESOURCE SETUP REQUEST message, the NG-
RAN node may use it to determine a priority for paging the UE in RRC_INACTIVE state.
For each requested PDU session, if resources are available for the requested configuration, the NG-RAN node shall
establish at least one DRB and associate each accepted QoS flow of the PDU session to a DRB established.
For each PDU session successfully established the NG-RAN node shall pass to the UE the PDU Session NAS-PDU IE,
if included, and the value contained in the PDU Session ID IE received for the PDU session. The NG-RAN node shall
not send to the UE the PDU Session NAS PDUs associated to the failed PDU sessions.
If the NAS-PDU IE is included in the PDU SESSION RESOURCE SETUP REQUEST message, the NG-RAN node
shall pass it to the UE.
For each PDU session the NG-RAN node shall store the UL NG-U UP TNL Information IE included in the PDU
Session Resource Setup Request Transfer IE contained in the PDU SESSION RESOURCE SETUP REQUEST message
and use it as the uplink termination point for the user plane data for this PDU session.
For each PDU session, if the Additional UL NG-U UP TNL Information IE is included in the PDU Session Resource
Setup Request Transfer IE contained in the PDU SESSION RESOURCE SETUP REQUEST message, the NG-RAN
node may allocate for this split PDU session resources for an additional NG-U transport bearer for some or all of the
QoS flows present in the QoS Flow Setup Request List IE and it shall indicate these QoS flows in the Additional DL
QoS Flow per TNL Information IE in the PDU Session Resource Setup Response Transfer IE. In case the Additional DL
QoS Flow per TNL Information IE is not included the SMF shall consider the proposed additional UL NG-U UP TNL
information as available again.
For each PDU session, if the Network Instance IE is included in the PDU Session Resource Setup Request Transfer IE
contained in the PDU SESSION RESOURCE SETUP REQUEST message, the NG-RAN node shall, if supported, use
it when selecting transport network resource as specified in TS 23.501 [9].
For each PDU session, if the PDU Session Type IE included in the PDU Session Resource Setup Request Transfer IE of
the PDU SESSION RESOURCE SETUP REQUEST message is set to "ethernet" or "unstructured", the NG-RAN node
shall not perform header compression for the concerned PDU session.
For each PDU session for which the Security Indication IE is included in the PDU Session Resource Setup Request
Transfer IE of the PDU SESSION RESOURCE SETUP REQUEST message, and the Integrity Protection Indication IE
or Confidentiality Protection Indication IE is set to "required", then the NG-RAN node shall perform user plane
integrity protection or ciphering, respectively, for the concerned PDU session. If the NG-RAN node cannot perform the
ETSI
user plane integrity protection or ciphering, it shall reject the setup of the PDU session resources with an appropriate
cause value.
If the NG-RAN node is an ng-eNB, it shall reject all PDU sessions for which the Integrity Protection Indication IE is
set to "required".
Transfer IE of the PDU SESSION RESOURCE SETUP REQUEST message, and the Integrity Protection Indication IE
or Confidentiality Protection Indication IE is set to "preferred", then the NG-RAN node should, if supported, perform
user plane integrity protection or ciphering, respectively, for the concerned PDU session and shall notify whether it
performed the user plane integrity protection or ciphering by including the Integrity Protection Result IE or
Confidentiality Protection Result IE, respectively, in the PDU Session Resource Setup Response Transfer IE of the
PDU SESSION RESOURCE SETUP RESPONSE message.
For each PDU session for which the Maximum Integrity Protected Data Rate Downlink IE or the Maximum Integrity
Protected Data Rate Uplink IE are included in the Security Indication IE in the PDU Session Resource Setup Request
Transfer IE of the PDU SESSION RESOURCE SETUP REQUEST message, the NG-RAN node shall store the
respective information and, if integrity protection is to be performed for the PDU session, it shall enforce the traffic
limits corresponding to the received values, for the concerned PDU session and concerned UE, as specified in TS
23.501 [9].
Transfer IE of the PDU SESSION RESOURCE SETUP REQUEST message:
- if the Integrity Protection Indication IE is set to "not needed", then the NG-RAN node shall not perform user
plane integrity protection for the concerned PDU session;
- if the Confidentiality Protection Indication IE is set to "not needed", then the NG-RAN node shall not perform
user plane ciphering for the concerned PDU session.
For each PDU session for which the PDU Session Aggregate Maximum Bit Rate IE is included in the PDU Session
Resource Setup Request Transfer IE of the PDU SESSION RESOURCE SETUP REQUEST message, the NG-RAN
node shall store the received value in the UE context and use it when enforcing traffic policing for Non-GBR QoS flows
for the concerned UE as specified in TS 23.501 [9].
For each PDU session in the PDU SESSION RESOURCE SETUP REQUEST message, if the Additional QoS Flow
Information IE is included in the QoS Flow Level QoS Parameters IE in the PDU Session Resource Setup Request
Transfer IE of the PDU SESSION RESOURCE SETUP REQUEST message, the NG-RAN node may consider it for
the DRB allocation process. It is up to NG-RAN node implementation to decide whether and how to use it.
For each QoS flow requested to be setup the NG-RAN node shall take into account the received QoS Flow Level QoS
Parameters IE. For each QoS flow the NG-RAN node shall establish or modify the resources according to the values of
the Allocation and Retention Priority IE (priority level and pre-emption indicators) and the resource situation as
follows:
- The NG-RAN node shall consider the priority level of the requested QoS flow, when deciding on the resource
allocation.
- The priority levels and the pre-emption indicators may (individually or in combination) be used to determine
whether the QoS flow setup has to be performed unconditionally and immediately. If the requested QoS flow is
marked as "may trigger pre-emption" and the resource situation requires so, the NG-RAN node may trigger the
pre-emption procedure which may then cause the forced release of a lower priority QoS flow which is marked as
"pre-emptable". Whilst the process and the extent of the pre-emption procedure are operator-dependent, the pre-
emption indicators shall be treated as follows:
1. The values of the last received Pre-emption Vulnerability IE and Priority Level IE shall prevail.
2. If the Pre-emption Capability IE is set to "may trigger pre-emption", then this allocation request may trigger
the pre-emption procedure.
3. If the Pre-emption Capability IE is set to "shall not trigger pre-emption", then this allocation request shall not
trigger the pre-emption procedure.
4. If the Pre-emption Vulnerability IE is set to "pre-emptable", then this QoS flow shall be included in the pre-
emption process.
ETSI
5. If the Pre-emption Vulnerability IE is set to "not pre-emptable", then this QoS flow shall not be included in
the pre-emption process.
- The NG-RAN node pre-emption process shall keep the following rules:
1. The NG-RAN node shall only pre-empt QoS flows with lower priority, in ascending order of priority.
2. The pre-emption may be done for QoS flows belonging to the same UE or to other UEs.
For each QoS flow which has been successfully established, the NG-RAN node shall store the mapped E-RAB ID if
included in the PDU Session Resource Setup Request Transfer IE contained in the PDU SESSION RESOURCE
SETUP REQUEST message and use it as specified in TS 38.300 [8].
The NG-RAN node shall report to the AMF in the PDU SESSION RESOURCE SETUP RESPONSE message the
result for each PDU session resource requested to be setup:
- For each PDU session resource successfully setup, the PDU Session Resource Setup Response Transfer IE shall
be included containing:
1. The NG-U UP transport layer information to be used for the PDU session and associated list of QoS flows
which have been successfully established, in the QoS Flow per TNL Information IE.
2. The list of QoS flows which failed to be established, if any, in the QoS Flow Failed to Setup List IE. When
the NG-RAN node reports unsuccessful establishment of a QoS flow, the cause value should be precise
enough to enable the SMF to know the reason for the unsuccessful establishment.
- For each PDU session resource which failed to be setup, the PDU Session Resource Setup Unsuccessful Transfer
IE shall be included containing a cause value that should be precise enough to enable the SMF to know the
reason for the unsuccessful establishment.
For each PDU session resource successfully setup at the NG-RAN node, if the Additional UL NG-U UP TNL
Information IE is included in the PDU Session Resource Setup Request Transfer IE the NG-RAN node may allocate
resources for an additional NG-U transport bearer for some or all QoS flows which it shall indicate in the Additional
QoS Flow per TNL Information IE in the PDU Session Resource Setup Response Transfer IE. In case the Additional
QoS Flow per TNL Information IE is not included the SMF shall consider the proposed additional UL NG-U UP TNL
information as available again.
Upon reception of the PDU SESSION RESOURCE SETUP RESPONSE message the AMF shall, for each PDU session
indicated in the PDU Session ID IE, transfer transparently the PDU Session Resource Setup Response Transfer IE or
PDU Session Resource Setup Unsuccessful Transfer IE to the SMF associated with the concerned PDU session.
The UE Aggregate Maximum Bit Rate IE should be sent to the NG-RAN node if the AMF has not sent it previously. If
it is included in the PDU SESSION RESOURCE SETUP REQUEST message, the NG-RAN node shall store the UE
Aggregate Maximum Bit Rate in the UE context, and use the received UE Aggregate Maximum Bit Rate for all Non-
GBR QoS flows for the concerned UE as specified in TS 23.501 [9].
Interactions with Handover Preparation procedure:
If a handover becomes necessary during the PDU Session Resource Setup procedure, the NG-RAN node may interrupt
the ongoing PDU Session Resource Setup procedure and initiate the Handover Preparation procedure as follows:
1. The NG-RAN node shall send the PDU SESSION RESOURCE SETUP RESPONSE message in which the NG-
RAN node shall indicate, if necessary, all the PDU session resources which failed to be setup with an appropriate
cause value, e.g. "NG intra-system handover triggered", "NG inter-system handover triggered" or "Xn handover
triggered".
2. The NG-RAN node shall trigger the handover procedure.
8.2.1.3 Unsuccessful Operation

The unsuccessful operation is specified in the successful operation section.
ETSI
8.2.1.4 Abnormal Conditions

If the NG-RAN node receives a PDU SESSION RESOURCE SETUP REQUEST message containing several PDU
Session ID IEs (in the PDU Session Resource Setup Request List IE) set to the same value, the NG-RAN node shall
report the establishment of the corresponding PDU sessions as failed in the PDU SESSION RESOURCE SETUP
RESPONSE message with an appropriate cause value.
If the NG-RAN node receives a PDU SESSION RESOURCE SETUP REQUEST message containing a PDU Session
ID IE (in the PDU Session Resource Setup Request List IE) set to a value that identifies an active PDU session
(established before the PDU SESSION RESOURCE SETUP REQUEST message was received), the NG-RAN node
shall report the establishment of the new PDU session as failed in the PDU SESSION RESOURCE SETUP REQUEST
message with an appropriate cause value.
8.2.2 PDU Session Resource Release
8.2.2.1 General
The purpose of the PDU Session Resource Release procedure is to enable the release of already established PDU
session resources for a given UE. The procedure uses UE-associated signalling.
Figure 8.2.2.2-1: PDU session resource release: successful operation
The AMF initiates the procedure by sending a PDU SESSION RESOURCE RELEASE COMMAND message.
The PDU SESSION RESOURCE RELEASE COMMAND message shall contain the information required by the NG-
RAN node to release at least one PDU session resource, and include each PDU session resource to release in the PDU
Session Resource to Release List IE.
If a NAS-PDU IE is contained in the PDU SESSION RESOURCE RELEASE COMMAND message, the NG-RAN
node shall pass it to the UE.
Upon reception of the PDU SESSION RESOURCE RELEASE COMMAND message the NG-RAN node shall execute
the release of the requested PDU sessions. For each PDU session to be released the NG-RAN node shall release the
corresponding resources over Uu and over NG.
If the RAN Paging Priority IE is included in the PDU SESSION RESOURCE RELEASE COMMAND message, the
NG-RAN node may use it to determine a priority for paging the UE in RRC_INACTIVE state.
The NG-RAN node shall, if supported, report in the PDU SESSION RESOURCE RELEASE RESPONSE message
location information of the UE in the User Location Information IE.
After sending a PDU SESSION RESOURCE RELEASE RESPONSE message, the NG-RAN node shall be prepared to
receive a PDU SESSION RESOURCE SETUP REQUEST message requesting establishment of a PDU session with a
PDU Session ID corresponding to one of the PDU Session IDs that was present in the PDU Session Resource to
Release List IE of the PDU SESSION RESOURCE RELEASE COMMAND message.
If the User Location Information IE is included in the PDU SESSION RESOURCE RELEASE RESPONSE message,
the AMF shall handle this information as specified in TS 23.501 [9].
ETSI
For each PDU session for which the Secondary RAT Usage Information IE is included in the PDU Session Resource
Release Response Transfer IE, the SMF shall handle this information as specified in TS 23.502 [10].


If the NG-RAN node receives a PDU SESSION RESOURCE RELEASE COMMAND message containing multiple
PDU Session ID IEs (in the PDU Session Resource to Release List IE) set to the same value, the NG-RAN node shall
initiate the release of one corresponding PDU session and ignore the duplication of the instances of the selected
corresponding PDU sessions.
If the NG-RAN node receives a PDU SESSION RESOURCE RELEASE COMMAND message containing PDU
Session ID IE(s) (in the PDU Session Resource to Release List IE) that the NG-RAN node does not recognize, the NG-
RAN node shall report the corresponding invalid PDU session(s) as failed in the PDU SESSION RESOURCE
RELEASE RESPONSE message with an appropriate cause value.
8.2.3 PDU Session Resource Modify
8.2.3.1 General
The purpose of the PDU Session Resource Modify procedure is to enable configuration modifications of already
established PDU session(s) for a given UE. It is also to enable the setup, modification and release of the QoS flow for
already established PDU session(s). The procedure uses UE-associated signalling.
Figure 8.2.3.2-1: PDU session resource modify: successful operation
The AMF initiates the procedure by sending a PDU SESSION RESOURCE MODIFY REQUEST message to the NG-
RAN node.
The PDU SESSION RESOURCE MODIFY REQUEST message shall contain the information required by the NG-
RAN node, which may trigger the NG-RAN configuration modification for the existing PDU sessions listed in the PDU
Session Resource Modify Request List IE.
Upon reception of the PDU SESSION RESOURCE MODIFY REQUEST message, if the NG-RAN configuration is
triggered to be modified and if resources are available for the modified NG-RAN configuration, the NG-RAN node
shall execute the configuration modification for the requested PDU session.
If the RAN Paging Priority IE is included in the PDU SESSION RESOURCE MODIFY REQUEST message, the NG-
RAN node may use it to determine a priority for paging the UE in RRC_INACTIVE state.
For each PDU session, if the S-NSSAI IE is included in the PDU Session Resource Modify Request Item IE contained in
the PDU SESSION RESOURCE MODIFY REQUEST message, the NG-RAN node shall replace the previously
provided S-NSSAI by the received S-NSSAI for the concerned PDU session.
ETSI
For each PDU session, if the Network Instance IE is included in the PDU Session Resource Modify Request Transfer IE
contained in the PDU SESSION RESOURCE MODIFY REQUEST message, the NG-RAN node shall, if supported,
use it as specified in TS 23.501 [9].
For each PDU session included in the PDU Session Resource Modify Request List IE:
- For each QoS flow included in the QoS Flow Add or Modify Request List IE, based on the QoS Flow Level QoS
Parameters IE, the NG-RAN node may establish, modify or release the DRB configuration and may change
allocation of resources on NG or Uu accordingly. The NG-RAN node shall associate each QoS flow accepted to
setup or modify with a DRB of the PDU session. The associated DRB for the QoS flow accepted to modify may
not change.
- For each QoS flow included in the QoS Flow to Release List IE, the NG-RAN node shall de-associate the QoS
flow with the previously associated DRB.
- The NG-RAN node shall pass the NAS-PDU IE received for the PDU session to the UE when modifying the
PDU session configuration. The NG-RAN node does not send the NAS PDUs associated to the failed PDU
sessions to the UE.
- The NG-RAN node may change allocation of resources on NG according to the requested target configuration.
- If the PDU Session Aggregate Maximum Bit Rate IE is included in the PDU Session Resource Modify Request
Transfer IE, the NG-RAN node shall store and use the received PDU Session Aggregate Maximum Bit Rate
value when enforcing traffic policing for Non-GBR QoS flows for the concerned UE as specified in TS 23.501
[9].
- If the UL NG-U UP TNL Modify List IE is included in the PDU Session Resource Modify Request Transfer IE,
the NG-RAN node shall update the transport layer information for the uplink data accordingly for the concerned
transport bearers identified by the DL NG-U UP TNL Information IE included in the PDU Session Resource
Modify Request Transfer IE for the concerned PDU session.
- If the Additional UL NG-U UP TNL Information IE is included in the PDU Session Resource Modify Request
Transfer IE, the NG-RAN node may allocate resources for an additional NG-U transport bearer for some or all
of the QoS flows present in the QoS Flow Add or Modify Request List IE and it shall indicate these QoS flows in
the Additional DL QoS Flow per TNL Information IE in the PDU Session Resource Modify Response Transfer
IE. In case the Additional DL QoS Flow per TNL Information IE is not included the SMF shall consider the
proposed additional UL NG-U UP TNL information as available again.
- In case more than one NG-U transport bearers have been set up for the PDU session, if all the QoS flows
associated to one existing NG-U transport bearer are included in the QoS Flow to Release List IE in the PDU
Session Resource Modify Request Transfer IE, the NG-RAN node and 5GC shall consider that the concerned
NG-U transport bearer is removed for the PDU session, and both NG-RAN node and 5GC shall therefore
consider the related NG-U UP TNL information as available again.
The NG-RAN node shall report to the AMF, in the PDU SESSION RESOURCE MODIFY RESPONSE message, the
result for each PDU session requested to be modified listed in the PDU SESSION RESOURCE MODIFY REQUEST
message:
- For each PDU session which is successfully modified, the PDU Session Resource Modify Response Transfer IE
shall be included containing:
1. The list of QoS flows which have been successfully setup or modified, if any, in the QoS Flow Add or Modify
Response List IE in case the PDU Session Resource Modify procedure is triggered by QoS flow setup or
modification.
2. The list of QoS flows which have failed to be setup or modified, if any, in the QoS Flow Failed to Add or
Modify List IE in case the PDU Session Resource Modify procedure is triggered by QoS flow setup or
modification.
- For each PDU session which failed to be modified, the PDU Session Resource Modify Unsuccessful Transfer IE
shall be included containing the failure cause.
- For each PDU session, if the DL NG-U UP TNL Information IE is included in the PDU Session Resource Modify
Response Transfer IE in the PDU SESSION RESOURCE MODIFY RESPONSE message, it shall be considered
by the SMF as the new DL transport layer address(es) for the PDU session. The NG-RAN also may indicate the
ETSI
mapping between each new DL transport layer address and the corresponding UL transport layer address
assigned by the 5GC.
Upon reception of the PDU SESSION RESOURCE MODIFY RESPONSE message the AMF shall, for each PDU
session indicated in the PDU Session ID IE, transfer transparently the PDU Session Resource Modify Response Transfer
IE or PDU Session Resource Modify Unsuccessful Transfer IE to each SMF associated with the concerned PDU
session.
The NG-RAN node shall, if supported, report in the PDU SESSION RESOURCE MODIFY RESPONSE message
location information of the UE in the User Location Information IE.
For a PDU session or a QoS flow which failed to be modified, the NG-RAN node shall fall back to the configuration of
the PDU session or the QoS flow as it was configured prior to the reception of the PDU SESSION RESOURCE
MODIFY REQUEST message.
Upon reception of the PDU SESSION RESOURCE MODIFY REQUEST message to setup a QoS flow for IMS voice,
if the NG-RAN node is not able to support IMS voice, the NG-RAN node shall initiate EPS fallback or RAT fallback
for IMS voice procedure as specified in TS 23.501 [9] and report unsuccessful establishment of the QoS flow in the
PDU Session Resource Modify Response Transfer IE or in the PDU Session Resource Modify Unsuccessful Transfer IE
with cause value "IMS voice EPS fallback or RAT fallback triggered".
If the User Location Information IE is included in the PDU SESSION RESOURCE MODIFY RESPONSE message,
the AMF shall handle this information as specified in TS 23.501 [9].
Interactions with Handover Preparation procedure:
If a handover becomes necessary during the PDU Session Resource Modify procedure, the NG-RAN node may
interrupt the ongoing PDU Session Resource Modify procedure and initiate the Handover Preparation procedure as
follows:
1. The NG-RAN node shall send the PDU SESSION RESOURCE MODIFY RESPONSE message in which the
NG-RAN node shall indicate, if necessary, all the PDU sessions failed with an appropriate cause value, e.g. "NG
intra-system handover triggered", "NG inter-system handover triggered" or "Xn handover triggered".
2. The NG-RAN node shall trigger the handover procedure.


If the NG-RAN node receives a PDU SESSION RESOURCE MODIFY REQUEST message containing several PDU
Session ID IEs (in the PDU Session Resource Modify Request List IE) set to the same value, the NG-RAN node shall
report the modification of the corresponding PDU sessions as failed in the PDU SESSION RESOURCE MODIFY
RESPONSE message with an appropriate cause value.
If the NG-RAN node receives a PDU SESSION RESOURCE MODIFY REQUEST message containing some PDU
Session ID IEs (in the PDU Session Resource Modify Request List IE) that the NG-RAN node does not recognize, the
NG-RAN node shall report the corresponding invalid PDU sessions as failed in the PDU SESSION RESOURCE
MODIFY RESPONSE message with an appropriate cause value.
8.2.4 PDU Session Resource Notify
8.2.4.1 General
The purpose of the PDU Session Resource Notify procedure is to notify that the already established QoS flow(s) or
PDU session(s) for a given UE are released or not fulfilled anymore or fulfilled again by the NG-RAN node for which
notification control is requested. The procedure uses UE-associated signalling.
ETSI
Figure 8.2.4.2-1: PDU session resource notify
The NG-RAN node initiates the procedure by sending a PDU SESSION RESOURCE NOTIFY message.
The PDU SESSION RESOURCE NOTIFY message shall contain the information of PDU session resources or QoS
flows which are released or not fulfilled anymore or fulfilled again by the NG-RAN node.
- For each PDU session for which some QoS flows are released or not fulfilled anymore or fulfilled again by the
NG-RAN node, the PDU Session Resource Notify Transfer IE shall be included containing:
1. The list of QoS flows which are released by the NG-RAN node, if any, in the QoS Flow Released List IE.
2. The list of GBR QoS flows which are not fulfilled anymore or fulfilled again by the NG-RAN node, if any, in
the QoS Flow Notify List IE together with the Notification Cause IE.
- For each PDU session resource which is released by the NG-RAN node, the PDU Session Resource Notify
Released Transfer IE shall be included containing the release cause in the Cause IE.
The NG-RAN node shall, if supported, report in the PDU SESSION RESOURCE NOTIFY message location
information of the UE in the User Location Information IE.
Upon reception of the PDU SESSION RESOURCE NOTIFY message, the AMF shall, for each PDU session indicated
in the PDU Session ID IE, transfer transparently the PDU Session Resource Notify Transfer IE or PDU Session
Resource Notify Released Transfer IE to the SMF associated with the concerned PDU session. Upon reception of PDU
Session Resource Notify Transfer IE, the SMF normally initiate the appropriate release or modify procedure on the core
network side for the PDU session(s) or QoS flow(s) identified as not fulfilled anymore.
Notify Transfer IE or the PDU Session Resource Notify Released Transfer IE, the SMF shall handle this information as
specified in TS 23.502 [10].
If the User Location Information IE is included in the PDU SESSION RESOURCE NOTIFY message, the AMF shall
handle this information as specified in TS 23.501 [9].

Void.
8.2.5 PDU Session Resource Modify Indication
8.2.5.1 General
The purpose of the PDU Session Resource Modify Indication procedure is for the NG-RAN node to request
modification of the established PDU session(s). The procedure uses UE-associated signalling.
ETSI
Figure 8.2.5.2-1: PDU session resource modify indication: successful operation
The NG-RAN node initiates the procedure by sending a PDU SESSION RESOURCE MODIFY INDICATION
message. Upon reception of the PDU SESSION RESOURCE MODIFY INDICATION message, the AMF shall, for
each PDU session indicated in the PDU Session ID IE, transparently transfer the PDU Session Resource Modify
Indication Transfer IE to the SMF associated with the concerned PDU session.
For each PDU session for which the DL QoS Flow per TNL Information IE is included in the PDU Session Resource
Modify Indication Transfer IE in the PDU SESSION RESOURCE MODIFY INDICATION message, the SMF shall
consider the included DL transport layer address as the new DL transport layer address for the included associated QoS
flows and it may provide the associated UL transport layer address in the UL NG-U UP TNL Information IE in the PDU
Session Resource Modify Confirm Transfer IE in the PDU SESSION RESOURCE MODIFY CONFIRM message.
For each PDU session for which the Additional DL QoS Flow per TNL Information IE is included in the PDU Session
Resource Modify Indication Transfer IE in the PDU SESSION RESOURCE MODIFY INDICATION message, the
SMF shall consider for this split PDU session each included DL transport layer address(es) as the new downlink
termination point(s) for the included associated QoS flows and it may provide the associated UL transport layer
address(s) in the Additional NG-U UP TNL Information IE in the PDU Session Resource Modify Confirm Transfer IE in
the PDU SESSION RESOURCE MODIFY CONFIRM message.
If the Security Result IE is included in the PDU Session Resource Modify Indication Transfer IE in the PDU SESSION
RESOURCE MODIFY INDICATION message, it may be considered by the SMF as the new security status of the PDU
session.
Modify Indication Transfer IE, the SMF shall handle this information as specified in TS 23.502 [10].
The AMF shall report to the NG-RAN node in the PDU SESSION MODIFY RESOURCE CONFIRM message the
result for each PDU session listed in PDU SESSION RESOURCE MODIFY INDICATION message:
- For each PDU session which is successfully modified, the PDU Session Resource Modify Confirm Transfer IE
shall be included containing:
1. The list of QoS flows which have been successfully modified in the QoS Flow Modify Confirm List IE.
2. The list of QoS flows which have failed to be modified, if any, in the QoS Flow Failed to Modify List IE.
- In case more than one NG-U transport bearers have been set up for the PDU session, if no QoS flow is
associated to one existing NG-U transport bearer after the modification, the NG-RAN node and 5GC shall
consider that the concerned NG-U transport bearer is removed for the PDU session, and both NG-RAN node and
5GC shall therefore consider the related NG-U UP TNL information as available again.
- For each PDU session which failed to be modified, the PDU Session Resource Modify Failed Transfer IE shall
be included to report the failure cause.
Upon reception of the PDU Session Resource Modify Confirm Transfer IE for each PDU session listed in the PDU
SESSION RESOURCE MODIFY CONFIRM message:
- If the QoS Flow Failed To Modify List IE is included, the NG-RAN node shall either
1. de-associate the corresponding DRB for the concerned QoS flow, or
ETSI
2. keep the previous transport layer information before sending the PDU SESSION RESOURCE MODIFY
INDICATION unchanged for the concerned QoS flow.
Upon reception of the PDU Session Resource Modify Failed Transfer IE for each PDU session listed in the PDU
SESSION RESOURCE MODIFY CONFIRM message, the NG-RAN node shall either:
1. release all corresponding NG-RAN configuration and resources for the concerned PDU session, or
2. keep the previous transport layer information before sending the PDU SESSION RESOURCE MODIFY
INDICATION unchanged for the concerned PDU session.

The purpose of the Initial Context Setup procedure is to establish the necessary overall initial UE context at the NG-
RAN node, when required, including PDU session context, the Security Key, Mobility Restriction List, UE Radio
Capability and UE Security Capabilities, etc. The AMF may initiate the Initial Context Setup procedure if a UE-
associated logical NG-connection exists for the UE or if the AMF has received the RAN UE NGAP ID IE in an
INITIAL UE MESSAGE message or if the NG-RAN node has already initiated a UE-associated logical NG-connection
by sending an INITIAL UE MESSAGE message via another NG interface instance. The procedure uses UE-associated
signalling.
Figure 8.3.1.2-1: Initial context setup: successful operation
In case of the establishment of a PDU session the 5GC shall be prepared to receive user data before the INITIAL
CONTEXT SETUP RESPONSE message has been received by the AMF. If no UE-associated logical NG-connection
exists, the UE-associated logical NG-connection shall be established at reception of the INITIAL CONTEXT SETUP
REQUEST message.
The INITIAL CONTEXT SETUP REQUEST message shall contain the Index to RAT/Frequency Selection Priority IE,
if available in the AMF.
If the NAS-PDU IE is included in the INITIAL CONTEXT SETUP REQUEST message, the NG-RAN node shall pass
it transparently towards the UE.
ETSI
If the Masked IMEISV IE is contained in the INITIAL CONTEXT SETUP REQUEST message the target NG-RAN
node shall, if supported, use it to determine the characteristics of the UE for subsequent handling.
Upon receipt of the INITIAL CONTEXT SETUP REQUEST message the NG-RAN node shall
- attempt to execute the requested PDU session configuration;
- store the received UE Aggregate Maximum Bit Rate in the UE context, and use the received UE Aggregate
Maximum Bit Rate for Non-GBR QoS flows for the concerned UE as specified in TS 23.501 [9];
- store the received Mobility Restriction List in the UE context;
- store the received UE Radio Capability in the UE context;
- store the received Index to RAT/Frequency Selection Priority in the UE context and use it as defined in TS
23.501 [9];
- store the received UE Security Capabilities in the UE context;
- store the received Security Key in the UE context and, if the NG-RAN node is required to activate security for
the UE, take this security key into use.
For the Initial Context Setup an initial value for the Next Hop Chaining Count is stored in the UE context.
If the PDU Session Resource Setup Request List IE is contained in the INITIAL CONTEXT SETUP REQUEST
message, the NG-RAN node shall behave the same as defined in the PDU Session Resource Setup procedure. The NG-
RAN node shall report to the AMF in the INITIAL CONTEXT SETUP RESPONSE message the result for each PDU
session resource requested to be setup as defined in the PDU Session Resource Setup procedure.
Upon reception of the INITIAL CONTEXT SETUP RESPONSE message the AMF shall, for each PDU session
PDU Session Resource Setup Unsuccessful Transfer IE to the SMF associated with the concerned PDU session. In case
the splitting PDU session is not used by the NG-RAN node, the SMF should remove the Additional Transport Layer
Information, if any.
The NG-RAN node shall use the information in the Mobility Restriction List IE if present in the INITIAL CONTEXT
SETUP REQUEST message to
- determine a target for subsequent mobility action for which the NG-RAN node provides information about the
target of the mobility action towards the UE;
- select a proper SCG during dual connectivity operation;
- assign proper RNA(s) for the UE when moving the UE to RRC_INACTIVE state.
If the Mobility Restriction List IE is not contained in the INITIAL CONTEXT SETUP REQUEST message, the NG-
RAN node shall consider that no roaming and no access restriction apply to the UE. The NG-RAN node shall also
consider that no roaming and no access restriction apply to the UE when:
- one of the QoS flows includes a particular ARP value (TS 23.501 [9]).
If the Trace Activation IE is included in the INITIAL CONTEXT SETUP REQUEST message the NG-RAN node shall,
if supported, initiate the requested trace function as described in TS 32.422 [11].
If the UE Security Capabilities IE included in the INITIAL CONTEXT SETUP REQUEST message only contains the
EIA0 or NIA0 algorithm as defined in TS 33.501 [13] and if the EIA0 or NIA0 algorithm is defined in the configured
list of allowed integrity protection algorithms in the NG-RAN node (TS 33.501 [13]), the NG-RAN node shall take it
into use and ignore the keys received in the Security Key IE.
If the Core Network Assistance Information IE is included in the INITIAL CONTEXT SETUP REQUEST message, the
NG-RAN node shall, if supported, store this information in the UE context and use it for e.g. the RRC_INACTIVE state
decision and RNA configuration for the UE and RAN paging if any for a UE in RRC_INACTIVE state, as specified in
TS 38.300 [8].
If the RRC Inactive Transition Report Request IE is included in the INITIAL CONTEXT SETUP REQUEST message,
the NG-RAN node shall, if supported, store this information in the UE context.
ETSI
If the Emergency Fallback Indicator IE is included in the INITIAL CONTEXT SETUP REQUEST message, it
indicates that the UE context to be set up is subject to emergency service fallback as described in TS 23.501 [9] and the
NG-RAN node may, if supported, take the appropriate mobility actions.
If the Old AMF IE is included in the INITIAL CONTEXT SETUP REQUEST message, the NG-RAN node shall
consider that this UE-associated logical NG-connection was redirected to this AMF from another AMF identified by the
Old AMF IE.
If the Redirection for Voice EPS Fallback IE is included in the INITIAL CONTEXT SETUP REQUEST message, the
NG-RAN node shall, if supported, store it and use it in a subsequent decision of EPS fallback for voice as specified in
TS 23.502 [10].
Interactions with Initial UE Message procedure:
The NG-RAN node shall use the AMF UE NGAP ID IE and RAN UE NGAP ID IE received in the INITIAL CONTEXT
SETUP REQUEST message as identification of the logical connection even if the RAN UE NGAP ID IE had been
allocated in an INITIAL UE MESSAGE message sent over a different NG interface instance.
Interactions with RRC Inactive Transition Report procedure:
If the RRC Inactive Transition Report Request IE is included in the INITIAL CONTEXT SETUP REQUEST message
and set to "subsequent state transition report", the NG-RAN node shall, if supported, send the RRC INACTIVE
TRANSITION REPORT message to the AMF to report the RRC state of the UE when the UE enters or leaves
RRC_INACTIVE state.
Figure 8.3.1.3-1: Initial context setup: unsuccessful operation
If the NG-RAN node is not able to establish an NG UE context, it shall consider the procedure as failed and reply with
the INITIAL CONTEXT SETUP FAILURE message.
If the PDU Session Resource Setup Request List IE is contained in the INITIAL CONTEXT SETUP REQUEST
message, the NG-RAN node shall report to the AMF, in the INITIAL CONTEXT SETUP FAILURE message, the
unsuccessful establishment result for each PDU session resource requested to be setup as defined in the PDU Session
Resource Setup procedure.
Upon reception of the INITIAL CONTEXT SETUP RESPONSE message the AMF shall, for each PDU session
PDU Session Resource Setup Unsuccessful Transfer IE to the SMF associated with the concerned PDU session. In case
the splitting PDU session is not used by the NG-RAN node, the SMF should remove the Additional Transport Layer
Information, if any.

If the supported algorithms for encryption defined in the Encryption Algorithms IE in the UE Security Capabilities IE,
plus the mandated support of EEA0 and NEA0 in all UEs (TS 33.501 [13]), do not match any allowed algorithms
defined in the configured list of allowed encryption algorithms in the NG-RAN node (TS 33.501 [13]), the NG-RAN
node shall reject the procedure using the INITIAL CONTEXT SETUP FAILURE message.
ETSI
If the supported algorithms for integrity defined in the Integrity Protection Algorithms IE in the UE Security
Capabilities IE, plus the mandated support of the EIA0 and NIA0 algorithm in all UEs (TS 33.501 [13]), do not match
any allowed algorithms defined in the configured list of allowed integrity protection algorithms in the NG-RAN node
(TS 33.501 [13]), the NG-RAN node shall reject the procedure using the INITIAL CONTEXT SETUP FAILURE
message.
8.3.2 UE Context Release Request (NG-RAN node initiated)
8.3.2.1 General
The purpose of the UE Context Release Request procedure is to enable the NG-RAN node to request the AMF to
release the UE-associated logical NG-connection due to NG-RAN node generated reasons. The procedure uses UE-
associated signalling.
Figure 8.3.2.2-1: UE context release request
The NG-RAN node controlling a UE-associated logical NG-connection initiates the procedure by sending a UE
CONTEXT RELEASE REQUEST message towards the affected AMF.
The UE CONTEXT RELEASE REQUEST message shall indicate the appropriate cause value, e.g., "TXnRELOCOverall
Expiry", "Redirection", for the requested UE-associated logical NG-connection release.
Interactions with UE Context Release procedure:
The UE Context Release procedure should be initiated upon reception of a UE CONTEXT RELEASE REQUEST
message.

Void.
8.3.3 UE Context Release (AMF initiated)
8.3.3.1 General
The purpose of the UE Context Release procedure is to enable the AMF to order the release of the UE-associated
logical NG-connection due to various reasons, e.g., completion of a transaction between the UE and the 5GC, or release
of the old UE-associated logical NG-connection when the UE has initiated the establishment of a new UE-associated
logical NG-connection, etc. The procedure uses UE-associated signalling.
ETSI
Figure 8.3.3.2-1: UE context release: successful operation
The AMF initiates the procedure by sending the UE CONTEXT RELEASE COMMAND message to the NG-RAN
node.
The UE CONTEXT RELEASE COMMAND message shall contain both the AMF UE NGAP ID IE and the RAN UE

handle this information as specified in TS 23.502 [10].
If the Information on Recommended Cells and RAN Nodes for Paging IE is included in the UE CONTEXT RELEASE
COMPLETE message, the AMF shall, if supported, store it and may use it for subsequent paging.
Release Response Transfer IE, the SMF shall handle this information as specified in TS 23.502 [10].

Not applicable.

If the UE Context Release procedure is not initiated towards the NG-RAN node before the expiry of the timer
TNGRELOCOverall, the NG-RAN node shall request the AMF to release the UE context.
If the UE returns to the NG-RAN node before the reception of the UE CONTEXT RELEASE COMMAND message or
the expiry of the timer TNGRELOCOverall, the NG-RAN node shall stop the timer TNGRELOCOverall and continue to serve the
UE.
8.3.4 UE Context Modification
8.3.4.1 General
The purpose of the UE Context Modification procedure is to partly modify the established UE context. The procedure
uses UE-associated signalling.
ETSI
Figure 8.3.4.2-1: UE context modification: successful operation
Upon receipt of the UE CONTEXT MODIFICATION REQUEST message the NG-RAN node shall

8.4 UE Mobility Management Procedures

8.4.1 Handover Preparation
8.4.1.1 General
The purpose of the Handover Preparation procedure is to request the preparation of resources at the target side via the
5GC. There is only one Handover Preparation procedure ongoing at the same time for a certain UE.
Figure 8.4.1.2-1: Handover preparation: successful operation
The source NG-RAN node initiates the handover preparation by sending the HANDOVER REQUIRED message to the
serving AMF. When the source NG-RAN node sends the HANDOVER REQUIRED message, it shall start the timer
TNGRELOCprep. The source NG-RAN node shall indicate the appropriate cause value for the handover in the Cause IE.
Upon reception of the HANDOVER REQUIRED message the AMF shall, for each PDU session indicated in the PDU
Session ID IE, transparently transfer the Handover Required Transfer IE to the SMF associated with the concerned
PDU session.
In case of intra-system handover, the information in the Source to Target Transparent Container IE shall be encoded
according to the definition of the Source NG-RAN node to Target NG-RAN node Transparent Container IE.
If the DL Forwarding IE is included for a given QoS flow in the PDU Session Resource Information Item IE within the
Source NG-RAN node to Target NG-RAN node Transparent Container IE of the HANDOVER REQUIRED message
and it is set to "DL forwarding proposed", it indicates that the source NG-RAN node proposes forwarding of downlink
data for that QoS flow.
If the DRBs to QoS Flows Mapping List IE is included in the PDU Session Resource Information Item IE within the
Source NG-RAN node to Target NG-RAN node Transparent Container IE of the HANDOVER REQUIRED message, it
implicitly indicates that the source NG-RAN node proposes forwarding of downlink data for those DRBs.
If the QoS Flow Mapping Indication IE for a QoS flow is included in the Associated QoS Flow List IE within the DRBs
to QoS Flows Mapping List IE within the Source NG-RAN node to Target NG-RAN node Transparent Container IE of
the HANDOVER REQUIRED message, it indicates that the source NG-RAN node has mapped only the uplink or
downlink of the QoS flow to the DRB.
If the HANDOVER COMMAND message contains the DL Forwarding UP TNL Information IE for a given DRB
within the Handover Command Transfer IE, the source NG-RAN node shall consider that the forwarding of downlink
data for this DRB is accepted by the target NG-RAN node. If the HANDOVER COMMAND message contains the UL
Forwarding UP TNL Information IE for a given DRB in the Data Forwarding Response DRB List IE within the
Handover Command Transfer IE, it means the target NG-RAN node has requested the forwarding of uplink data for this
DRB.
ETSI
In case of inter-system handover to LTE, the information in the Source to Target Transparent Container IE shall be
encoded according to the Source eNB to Target eNB Transparent Container IE definition as specified in TS 36.413
[16].
If the Direct Forwarding Path Availability IE is included in the HANDOVER REQUIRED message the AMF shall
handle it as specified in TS 23.502 [10].
If the Direct Forwarding Path Availability IE is included within the Handover Required Transfer IE of the
HANDOVER REQUIRED message the SMF shall handle it as specified in TS 23.502 [10].
When the preparation, including the reservation of resources at the target side is ready, the AMF responds with the
HANDOVER COMMAND message to the source NG-RAN node.
Upon reception of the HANDOVER COMMAND message the source NG-RAN node shall stop the timer TNGRELOCprep
and start the timer TNGRELOCoverall.
If there are any PDU Sessions that could not be admitted in the target, they shall be indicated in the PDU Session
Resources to Release List IE.
If the HANDOVER COMMAND message contains the QoS Flow to be Forwarded List IE within the Handover
Command Transfer IE for a given PDU session, then the source NG-RAN node should initiate data forwarding for the
listed QoS flows over the forwarding tunnel specified in the DL Forwarding UP TNL Information IE as specified in TS
38.300 [8].
If the HANDOVER COMMAND message contains the Additional DL Forwarding UP TNL Information IE within the
Handover Command Transfer IE, the source NG-RAN node should initiate data forwarding of the PDU session split in
different tunnel and shall use the received UP transport layer information for the forwarding QoS flows associated to it.
If the Target to Source Transparent Container IE has been received by the AMF from the handover target then the
transparent container shall be included in the HANDOVER COMMAND message.
In case of inter-system handover to LTE, the information in the Target to Source Transparent Container IE shall be
encoded according to the definition of the Target eNB to Source eNB Transparent Container IE as specified in TS
36.413 [16].
If the Index to RAT/Frequency Selection Priority IE is contained in the Source NG-RAN Node to Target NG-RAN Node
Transparent Container IE, the target NG-RAN node shall store the content of the received Index to RAT/Frequency
Selection Priority IE in the UE context and use it as defined in TS 23.501 [9].
Interactions with other NGAP procedures:
If, after a HANDOVER REQUIRED message is sent and before the Handover Preparation procedure is terminated, the
source NG-RAN node receives an AMF initiated PDU Session Management procedure on the same UE-associated
signalling connection, the source NG-RAN node shall either:
1. Cancel the Handover Preparation procedure by executing the Handover Cancellation procedure with an
appropriate cause value. After successful completion of the Handover Cancellation procedure, the source NG-
RAN node shall continue the AMF initiated PDU Session Management procedure.
or
2. Terminate the AMF initiated PDU Session Management procedure by sending the appropriate response message
with an appropriate cause value, e.g. "NG intra-system handover triggered" or "NG inter-system handover
triggered" to the AMF and then the source NG-RAN node shall continue with the handover procedure.
ETSI
Figure 8.4.1.3-1: Handover preparation: unsuccessful operation
If the 5GC or the target side is not able to accept any of the PDU session resources or a failure occurs during the
Handover Preparation, the AMF sends the HANDOVER PREPARATION FAILURE message with an appropriate
cause value to the source NG-RAN node.
Interaction with Handover Cancel procedure:
If there is no response from the AMF to the HANDOVER REQUIRED message before timer TNGRELOCprep expires in
the source NG-RAN node, the source NG-RAN node should cancel the Handover Preparation procedure by initiating
the Handover Cancel procedure with the appropriate value for the Cause IE. The source NG-RAN node shall ignore any
HANDOVER COMMAND message or HANDOVER PREPARATION FAILURE message received after the initiation
of the Handover Cancel procedure.

If the NG-RAN node receives at least one PDU Session ID included in the PDU Session Resource Handover List IE
without at least one valid associated GTP tunnel address pair (in either UL or DL), then the NG-RAN node shall
consider it as a logical error and act as described in subclause 10.4. A GTP tunnel address pair is considered valid if
both the GTP-TEID IE and the Endpoint IP Address IE are present.
8.4.2 Handover Resource Allocation
8.4.2.1 General
The purpose of the Handover Resource Allocation procedure is to reserve resources at the target NG-RAN node for the
handover of a UE.
Figure 8.4.2.2-1: Handover resource allocation: successful operation
The AMF initiates the procedure by sending the HANDOVER REQUEST message to the target NG-RAN node.
If the Masked IMEISV IE is contained in the HANDOVER REQUEST message the target NG-RAN node shall, if
supported, use it to determine the characteristics of the UE for subsequent handling.
ETSI
Upon receipt of the HANDOVER REQUEST message the target NG-RAN node shall
- attempt to execute the requested PDU session configuration and associated security;
- store the received UE Aggregate Maximum Bit Rate in the UE context, and use the received UE Aggregate
Maximum Bit Rate for all Non-GBR QoS flows for the concerned UE as specified in TS 23.501 [9];
- store the received Mobility Restriction List in the UE context;
- store the received UE Security Capabilities in the UE context;
- store the received Security Context in the UE context and take it into use as defined in TS 33.501 [13].
Upon reception of the UE History Information IE, which is included within the Source to Target Transparent Container
IE of the HANDOVER REQUEST message, the target NG-RAN node shall collect the information defined as
mandatory in the UE History Information IE and shall, if supported, collect the information defined as optional in the
UE History Information IE, for as long as the UE stays in one of its cells, and store the collected information to be used
for future handover preparations.
Upon receiving the PDU Session Resource Setup List IE contained in the HANDOVER REQUEST message, the target
NG-RAN node shall behave the same as defined in the PDU Session Resource Setup procedure. The target NG-RAN
node shall report to the AMF in the HANDOVER REQUEST ACKNOWLEDGE message the result for each PDU
session resource requested to be setup. In particular, for each PDU session resource successfully setup, it shall include
the Handover Request Acknowledge Transfer IE containing the following information:
- The list of QoS flows which have been successfully established in the QoS Flow Setup Response List IE.
- The Data Forwarding Accepted IE if the data forwarding for the QoS flow is accepted.
- The list of QoS flows which have failed to be established, if any, in the QoS Flow Failed to Setup List IE.
- The UP transport layer information to be used for the PDU session.
- The security result associated to the PDU session.
For each PDU session resource which failed to be setup, the Handover Resource Allocation Unsuccessful Transfer IE
shall be included in the HANDOVER REQUEST ACKNOWLEDGE message containing a cause value that should be
precise enough to enable the SMF to know the reason for the unsuccessful establishment.
Upon reception of the HANDOVER REQUEST ACKNOWLEDGE message the AMF shall, for each PDU session
indicated in the PDU Session ID IE, transfer transparently the Handover Request Acknowledge Transfer IE or Handover
Resource Allocation Unsuccessful Transfer IE to the SMF associated with the concerned PDU session.
If the HANDOVER REQUEST message contains the Data Forwarding Not Possible IE associated with a given PDU
session within the Handover Request Transfer IE set to "data forwarding not possible", the target NG-RAN node may
not include the DL Forwarding UP TNL Information IE and for intra-system handover the Data Forwarding Response
DRB List IE within the Handover Request Acknowledge Transfer IE in the HANDOVER REQUEST
ACKNOWLEDGE message for that PDU session.
In case of intra-system handover, if the target NG-RAN node accepts the downlink data forwarding for at least one QoS
flow for which the DL Forwarding IE is set to "DL forwarding proposed", it may include the DL Forwarding UP TNL
Information IE in the Handover Request Acknowledge Transfer IE as forwarding tunnel for the QoS flows listed in the
QoS Flow Setup Response List IE of the HANDOVER REQUEST ACKNOWLEDGE message.
In case of intra-system handover, for each PDU session for which the Additional DL UP TNL Information for HO List
IE is included in the Handover Request Acknowledge Transfer IE of the HANDOVER REQUEST ACKNOWLEDGE
message, the SMF shall consider the included Additional DL NG-U UP TNL Information IE as the downlink
termination point for the associated flows indicated in the Additional QoS Flow Setup Response List IE for this PDU
session split in different tunnels and shall consider the Additional DL Forwarding UP TNL Information IE, if included,
as the forwarding tunnel associated to these QoS flows.
In case of intra-system handover, if the target NG-RAN node accepts the data forwarding for a successfully configured
DRB, the target NG-RAN node may include the DL Forwarding UP TNL Information IE for the DRB within the Data
Forwarding Response DRB List IE within Handover Request Acknowledge Transfer IE of the HANDOVER REQUEST
ACKNOWLEDGE message.
ETSI
If the HANDOVER REQUEST ACKNOWLEDGE message contains the UL Forwarding UP TNL Information IE for a
given DRB in the Data Forwarding Response DRB List IE within the Handover Request Acknowledge Transfer IE, it
indicates the target NG-RAN node has requested the forwarding of uplink data for the DRB.
In case of inter-system handover from E-UTRAN, the target NG-RAN node includes the Data Forwarding Accepted IE
for each QoS flow that the DL Forwarding IE is set to "DL forwarding proposed" for the corresponding E-RAB in the
Source NG-RAN Node to Target NG-RAN Node Transparent Container IE and that the target NG-RAN node has
admitted the proposed forwarding of downlink data for the QoS flow. If the target NG-RAN node accepts the downlink
data forwarding for at least one QoS flow of an admitted PDU session it shall include the DL Forwarding UP TNL
Information IE in the PDU Session Resource Setup Response Transfer IE for that PDU session within the PDU Session
Resources Admitted List IE of the HANDOVER REQUEST ACKNOWLEDGE message.
The target NG-RAN node shall use the information in the Mobility Restriction List IE if present in the HANDOVER
REQUEST message to
- determine a target for subsequent mobility action for which the target NG-RAN node provides information about
the target of the mobility action towards the UE;
If the Mobility Restriction List IE is not contained in the HANDOVER REQUEST message, the target NG-RAN node
shall consider that no roaming and no access restriction apply to the UE. The target NG-RAN node shall also consider
that no roaming and no access restriction apply to the UE when:
- one of the QoS flows includes a particular ARP value (TS 23.501 [9]).
If the Trace Activation IE is included in the HANDOVER REQUEST message the target NG-RAN node shall, if
supported, initiate the requested trace function as described in TS 32.422 [11].
If the Location Reporting Request Type IE is included in the HANDOVER REQUEST message, the target NG-RAN
node should perform the requested location reporting functionality for the UE as described in subclause 8.12.
If the Core Network Assistance Information IE is included in the HANDOVER REQUEST message, the target NG-
RAN node shall, if supported, store this information in the UE context and use it for e.g. the RRC_INACTIVE state
decision and RNA configuration for the UE and RAN paging if any for a UE in RRC_INACTIVE state, as specified in
TS 38.300 [8].
If the New Security Context Indicator IE is included in the HANDOVER REQUEST message, the target NG-RAN node
shall use the information as specified in TS 33.501 [13].
If the NASC IE is included in the HANDOVER REQUEST message, the target NG-RAN node shall use it towards the
UE as specified in TS 33.501 [13].
If the RRC Inactive Transition Report Request IE is included in the HANDOVER REQUEST message, the NG-RAN
node shall, if supported, store this information in the UE context.
If the Redirection for Voice EPS Fallback IE is included in the HANDOVER REQUEST message, the NG-RAN node
shall, if supported, store it and use it in a subsequent decision of EPS fallback for voice as specified in TS 23.502 [10].
After all necessary resources for the admitted PDU session resources have been allocated, the target NG-RAN node
shall generate the HANDOVER REQUEST ACKNOWLEDGE message.
If the RRC Inactive Transition Report Request IE is included in the HANDOVER REQUEST message and set to
"subsequent state transition report", the NG-RAN node shall, if supported, send the RRC INACTIVE TRANSITION
REPORT message to the AMF to report the RRC state of the UE when the UE enters or leaves RRC_INACTIVE state.
ETSI
Figure 8.4.2.3-1: Handover resource allocation: unsuccessful operation
If the target NG-RAN node does not admit any of the PDU session resources, or a failure occurs during the Handover
Preparation, it shall send the HANDOVER FAILURE message to the AMF with an appropriate cause value.

If the supported algorithms for encryption defined in the Encryption Algorithms IE in the UE Security Capabilities IE,
plus the mandated support of EEA0 and NEA0 in all UEs (TS 33.501 [13]), do not match any allowed algorithms
defined in the configured list of allowed encryption algorithms in the NG-RAN node (TS 33.501 [13]), the target NG-
RAN node shall reject the procedure using the HANDOVER FAILURE message.
If the supported algorithms for integrity defined in the Integrity Protection Algorithms IE in the UE Security
Capabilities IE, plus the mandated support of the EIA0 and NIA0 algorithm in all UEs (TS 33.501 [13]), do not match
any allowed algorithms defined in the configured list of allowed integrity protection algorithms in the NG-RAN node
(TS 33.501 [13]), the target NG-RAN node shall reject the procedure using the HANDOVER FAILURE message.
If the target NG-RAN node receives a HANDOVER REQUEST message which does not contain the Mobility
Restriction List IE, and the serving PLMN cannot be determined otherwise by the NG-RAN node, the target NG-RAN
node shall reject the procedure using the HANDOVER FAILURE message.
If the target NG-RAN node receives a HANDOVER REQUEST message containing the Mobility Restriction List IE,
and the serving PLMN indicated is not supported by the target cell, the target NG-RAN node shall reject the procedure
using the HANDOVER FAILURE message.
8.4.3 Handover Notification
8.4.3.1 General
The purpose of the Handover Notification procedure is to indicate to the AMF that the UE has arrived to the target cell
and the NG-based handover has been successfully completed.

Session ID IE, transparently transfer the Path Switch Request Transfer IE to the SMF associated with the concerned
PDU session.
After all necessary updates including the UP path switch have been successfully completed in the 5GC for at least one
of the PDU session resources included in the PATH SWITCH REQUEST, the AMF shall send the PATH SWITCH
REQUEST ACKNOWLEDGE message to the NG-RAN node and the procedure ends.
The list of accepted QoS flows shall be included in the PATH SWITCH REQUEST message within the Path Switch
Request Transfer IE. The SMF shall handle this information as specified in TS 23.502 [10].
For each PDU session for which the Additional DL QoS Flow per TNL Information IE is included in the Path Switch
Request Transfer IE of the PATH SWITCH REQUEST message, the SMF may use each included UP transport layer
information as the downlink termination point for the included associated QoS flows for this PDU session split in
different tunnels.

within the Path Switch Request Setup Failed Transfer IE. The AMF shall handle this information as specified in TS
23.502 [10].
For each PDU session for which the User Plane Security Information IE is included in the Path Switch Request
Transfer IE of the PATH SWITCH REQUEST message, the SMF shall behave as specified in TS 33.501 [13] and may
send back the Security Indication IE within the Path Switch Request Acknowledge Transfer IE of the PATH SWITCH
REQUEST ACKNOWLEDGE message.
For each PDU session for which the DL NG-U TNL Information Reused IE set to "true" is included in the Path Switch
Request Transfer IE of the PATH SWITCH REQUEST message, the SMF shall, if supported, consider that the DL
TNL information contained in the DL NG-U UP TNL Information IE has been reused.

ETSI
Figure 8.4.4.3-1: Path switch request: unsuccessful operation
If the 5GC fails to switch the downlink termination point of the NG-U transport bearer towards a new termination point
for all PDU session resources, the AMF shall send the PATH SWITCH REQUEST FAILURE message to the NG-RAN
node.
The NG-RAN node shall release the corresponding QoS flows and regard the PDU session(s) indicated in the PDU
Session Resource Released List IE included in the PATH SWITCH REQUEST FAILURE message as being released.
The appropriate cause value for each PDU session released is included in the Path Switch Request Unsuccessful
Transfer IE contained in the PATH SWITCH REQUEST FAILURE message.

If the AMF receives a PATH SWITCH REQUEST message containing several PDU Session ID IEs (in the PDU
Session Resource to be Switched in Downlink List IE) set to the same value, the AMF shall send the PATH SWITCH
REQUEST FAILURE message to the NG-RAN node.
8.4.5 Handover Cancellation
8.4.5.1 General
The purpose of the Handover Cancellation procedure is to enable a source NG-RAN node to cancel an ongoing
handover preparation or an already prepared handover. The procedure uses UE-associated signalling.
Figure 8.4.5.2-1: Handover cancel: successful operation
The source NG-RAN node initiates the procedure by sending a HANDOVER CANCEL message to the AMF.

Not applicable.
ETSI

If the source NG-RAN node becomes aware of the fact that an expected HANDOVER CANCEL ACKNOWLEDGE
message is missing, the source NG-RAN node shall consider the Handover Cancellation procedure as successfully
terminated.
8.4.6 Uplink RAN Status Transfer
8.4.6.1 General
The purpose of the Uplink RAN Status Transfer procedure is to enable lossless NG-based handover. The procedure uses
UE-associated signalling.
Figure 8.4.6.2-1: Uplink RAN status transfer
The source NG-RAN node initiates the procedure by stopping the assigning of PDCP-SNs to downlink SDUs and
sending the UPLINK RAN STATUS TRANSFER message to the AMF at the point in time when it considers the
transmitter/receiver status to be frozen.
For each DRB for which PDCP-SN and HFN status preservation applies, the source NG-RAN node shall include the
DRB ID IE, the UL COUNT Value IE and the DL COUNT Value IE within the DRBs Subject to Status Transfer List IE
in the RAN Status Transfer Transparent Container IE of the UPLINK RAN STATUS TRANSFER message.
The source NG-RAN node may also include in the UPLINK RAN STATUS TRANSFER message the missing and the
received uplink SDUs in the Receive Status of UL PDCP SDUs IE for each DRB for which the source NG-RAN node
has accepted the request from the target NG-RAN node for uplink forwarding.

Void.
8.4.7 Downlink RAN Status Transfer
8.4.7.1 General
The purpose of the Downlink RAN Status Transfer procedure is to is to enable lossless NG-based handover. The
procedure uses UE-associated signalling.
ETSI
Figure 8.4.7.2-1: Downlink RAN status transfer
The AMF initiates the procedure by sending the DOWNLINK RAN STATUS TRANSFER message to the target NG-
RAN node. The target NG-RAN node using Full Configuration for this handover as per TS 38.300 [8] shall ignore the
information received in this message.
For each DRB in the DRBs Subject to Status Transfer List IE within the RAN Status Transfer Transparent Container IE,
the target NG-RAN node shall not deliver any uplink packet which has a PDCP-SN lower than the value of the UL
Count Value IE.
For each DRB in the DRBs Subject to Status Transfer List IE within the RAN Status Transfer Transparent Container IE,
the target NG-RAN node shall use the value of the DL COUNT Value IE for the first downlink packet for which there is
no PDCP-SN yet assigned.
If the Receive Status of UL PDCP SDUs IE is included for at least one DRB in the RAN Status Transfer Transparent
Container IE of the DOWNLINK RAN STATUS TRANSFER message, the target NG-RAN node may use it in a
Status Report message sent to the UE over the radio interface.

If the target NG-RAN node receives this message for a UE for which no prepared handover exists at the target NG-
RAN node, the target NG-RAN node shall ignore the message.
8.5 Paging Procedures

8.5.1 Paging
8.5.1.1 General
The purpose of the Paging procedure is to enable the AMF to page a UE in the specific NG-RAN node.
Figure 8.5.1.2-1: Paging
ETSI
The AMF initiates the Paging procedure by sending the PAGING message to the NG-RAN node.
At the reception of the PAGING message, the NG-RAN node shall perform paging of the UE in cells which belong to
tracking areas as indicated in the TAI List for Paging IE.
If the Paging DRX IE is included in the PAGING message, the NG-RAN node shall use it according to TS 38.304 [12]
and TS 36.304 [29].
For each cell that belongs to any of the tracking areas indicated in the TAI List for Paging IE, the NG-RAN node shall
generate one page on the radio interface.
If the Paging Priority IE is included in the PAGING message, the NG-RAN node may use it according to TS 23.501
[9].
If the UE Radio Capability for Paging IE is included in the PAGING message, the NG-RAN node may use it to apply
specific paging schemes.
If the Assistance Data for Recommended Cells IE is included in the Assistance Data for Paging IE it may be used,
together with the Paging Attempt Information IE if also present, according to TS 38.300 [8].
If the Next Paging Area Scope IE is included in the Paging Attempt Information IE it may be used for paging the UE
according to TS 38.300 [8].

8.6 Transport of NAS Messages Procedures

8.6.1 Initial UE Message
8.6.1.1 General
The Initial UE Message procedure is used when the NG-RAN node has received from the radio interface the first uplink
NAS message transmitted on an RRC connection to be forwarded to an AMF.
Figure 8.6.1.2-1: Initial UE message
The NG-RAN node initiates the procedure by sending an INITIAL UE MESSAGE message to the AMF. The NG-RAN
node shall allocate a unique RAN UE NGAP ID to be used for the UE and the NG-RAN node shall include this identity
in the INITIAL UE MESSAGE message.
The NAS-PDU IE contains a UE – AMF message that is transferred without interpretation in the NG-RAN node.
ETSI
In case of network sharing, the selected PLMN is indicated by the PLMN Identity IE within the TAI IE included in the
INITIAL UE MESSAGE message.
When the NG-RAN node has received from the radio interface the 5G-S-TMSI IE, it shall include it in the INITIAL UE
MESSAGE message.
If the AMF Set ID IE is included in the INITIAL UE MESSAGE message this indicates that the message is a rerouted
message and the AMF shall, if supported, use the IE as described in TS 23.502 [10].
If the UE Context Request IE is included in the INITIAL UE MESSAGE message the AMF shall trigger an Initial
Context Setup procedure towards the NG-RAN node.
If the Allowed NSSAI IE is included in the INITIAL UE MESSAGE message the AMF shall use the IE as defined in TS
23.502 [10].

If the 5G-S-TMSI is not received by the AMF in the INITIAL UE MESSAGE message whereas expected, the AMF
shall consider the procedure as failed.
8.6.2 Downlink NAS Transport
8.6.2.1 General
The Downlink NAS Transport procedure is used when the AMF only needs to send a NAS message transparently via
the NG-RAN node to the UE, and a UE-associated logical NG-connection exists for the UE or the AMF has received
the RAN UE NGAP ID IE in an INITIAL UE MESSAGE message or if the NG-RAN node has already initiated a UE-
associated logical NG-connection by sending an INITIAL UE MESSAGE message via another NG interface instance.
Figure 8.6.2.2-1: Downlink NAS transport
The AMF initiates the procedure by sending a DOWNLINK NAS TRANSPORT message to the NG-RAN node. If the
UE-associated logical NG-connection is not established, the AMF shall allocate a unique AMF UE NGAP ID to be used
for the UE and include that in the DOWNLINK NAS TRANSPORT message; by receiving the AMF UE NGAP ID IE
in the DOWNLINK NAS TRANSPORT message, the NG-RAN node establishes the UE-associated logical NG-
connection.
If the RAN Paging Priority IE is included in the DOWNLINK NAS TRANSPORT message, the NG-RAN node may
use it to determine a priority for paging the UE in RRC_INACTIVE state.
The NAS-PDU IE contains an AMF – UE message that is transferred without interpretation in the NG-RAN node.
If the Mobility Restriction List IE is contained in the DOWNLINK NAS TRANSPORT message, the NG-RAN node
shall store this information in the UE context. The NG-RAN node shall use the information in the Mobility Restriction
List IE if present in the DOWNLINK NAS TRANSPORT message to:
- determine a target for subsequent mobility action for which the NG-RAN node provides information about the
target of the mobility action towards the UE;
ETSI
If the Mobility Restriction List IE is not contained in the DOWNLINK NAS TRANSPORT message and there is no
previously stored mobility restriction information, the NG-RAN node shall consider that no roaming and no access
restriction apply to the UE.
If the Index to RAT/Frequency Selection Priority IE is included in the DOWNLINK NAS TRANSPORT message, the
NG-RAN node shall, if supported, use it as defined in TS 23.501 [9].
The UE Aggregate Maximum Bit Rate IE should be sent to the NG-RAN node if the AMF has not sent it previously. If
it is included in the DOWNLINK NAS TRANSPORT message, the NG-RAN node shall store the UE Aggregate
Maximum Bit Rate in the UE context, and use the received UE Aggregate Maximum Bit Rate for all Non-GBR QoS
flows for the concerned UE as specified in TS 23.501 [9].
If the Old AMF IE is included in the DOWNLINK NAS TRANSPORT message, the NG-RAN node shall consider that
this UE-associated logical NG-connection was redirected to this AMF from another AMF identified by the Old AMF
IE.
Interactions with Initial UE Message procedure:
The NG-RAN node shall use the AMF UE NGAP ID IE and RAN UE NGAP ID IE received in the DOWNLINK NAS
TRANSPORT message as identification of the logical connection even if the RAN UE NGAP ID IE had been allocated
in an INITIAL UE MESSAGE message sent over a different NG interface instance.

Void.
8.6.3 Uplink NAS Transport
8.6.3.1 General
The Uplink NAS Transport procedure is used when the NG-RAN node has received from the radio interface a NAS
message to be forwarded to the AMF to which a UE-associated logical NG-connection for the UE exists.
Figure 8.6.3.2-1: Uplink NAS transport
The NG-RAN node initiates the procedure by sending an UPLINK NAS TRANSPORT message to the AMF.
The NAS-PDU IE contains a UE – AMF message that is transferred without interpretation in the NG-RAN node.

Void.
ETSI
8.6.4 NAS Non Delivery Indication
8.6.4.1 General
The NAS Non Delivery Indication procedure is used when the NG-RAN node decides not to start the delivery of a NAS
message that has been received over a UE-associated logical NG-connection or the NG-RAN node is unable to ensure
that the message has been received by the UE.
Figure 8.6.4.2-1: NAS non delivery indication
The NG-RAN node initiates the procedure by sending a NAS NON DELIVERY INDICATION message to the AMF.
The NG-RAN node shall report the non-delivery of a NAS message by including the non-delivered NAS message
within the NAS-PDU IE and an appropriate cause value within the Cause IE, e.g., "NG intra system handover
triggered", "NG inter system handover triggered" or "Xn handover triggered".

Void.
8.6.5 Reroute NAS Request
8.6.5.1 General
The purpose of the Reroute NAS Request procedure is to enable the AMF to request for a rerouting of the INITIAL UE
MESSAGE message to another AMF.
Figure 8.6.5.2-1: Reroute NAS request
The AMF initiates the procedure by sending a REROUTE NAS REQUEST message to the NG-RAN node. The NG-
RAN node shall, if supported, reroute the INITIAL UE MESSAGE message to an AMF indicated by the AMF Set ID IE
as described in TS 23.501 [9].
ETSI
If the Allowed NSSAI IE is included in the REROUTE NAS REQUEST message, then the NG-RAN node shall
propagate it in the rerouted INITIAL UE MESSAGE message as defined in TS 23.502 [10].

Void.
8.7 Interface Management Procedures

8.7.1 NG Setup
8.7.1.1 General
The purpose of the NG Setup procedure is to exchange application level data needed for the NG-RAN node and the
AMF to correctly interoperate on the NG-C interface. This procedure shall be the first NGAP procedure triggered after
the TNL association has become operational. The procedure uses non-UE associated signalling.
This procedure erases any existing application level configuration data in the two nodes, replaces it by the one received
and clears AMF overload state information at the NG-RAN node. If the NG-RAN node and AMF do not agree on
retaining the UE contexts this procedure also re-initialises the NGAP UE-related contexts (if any) and erases all related
signalling connections in the two nodes like an NG Reset procedure would do.
Figure 8.7.1.2-1: NG setup: successful operation
The NG-RAN node initiates the procedure by sending an NG SETUP REQUEST message including the appropriate
data to the AMF. The AMF responds with an NG SETUP RESPONSE message including the appropriate data.
If the UE Retention Information IE set to “ues-retained“ is included in the NG SETUP REQUEST message, the AMF
may accept the proposal to retain the existing UE related contexts and signalling connections by including the UE
Retention Information IE set to “ues-retained“ in the NG SETUP RESPONSE message.
Figure 8.7.1.3-1: NG setup: unsuccessful operation
ETSI
If the AMF cannot accept the setup, it should respond with an NG SETUP FAILURE message and appropriate cause
value.
If the NG SETUP FAILURE message includes the Time to Wait IE, the NG-RAN node shall wait at least for the
indicated time before reinitiating the NG Setup procedure towards the same AMF.

If the NG-RAN node initiates the procedure by sending an NG SETUP REQUEST message including the PLMN
Identity IEs and none of the PLMNs provided by the NG-RAN node is identified by the AMF, then the AMF shall
reject the NG Setup procedure with an appropriate cause value.
8.7.2 RAN Configuration Update
8.7.2.1 General
The purpose of the RAN Configuration Update procedure is to update application level configuration data needed for
the NG-RAN node and the AMF to interoperate correctly on the NG-C interface. This procedure does not affect
existing UE-related contexts, if any.
Figure 8.7.2.2-1: RAN configuration update: successful operation
The NG-RAN node initiates the procedure by sending a RAN CONFIGURATION UPDATE message to the AMF
including an appropriate set of updated configuration data that it has just taken into operational use. The AMF responds
with a RAN CONFIGURATION UPDATE ACKNOWLEDGE message to acknowledge that it successfully updated
the configuration data. If an information element is not included in the RAN CONFIGURATION UPDATE message,
the AMF shall interpret that the corresponding configuration data is not changed and shall continue to operate the NG-C
interface with the existing related configuration data.
If the Supported TA List IE is included in the RAN CONFIGURATION UPDATE message, the AMF shall overwrite
the whole list of supported TAs and the corresponding list of supported slices for each TA, and use them for subsequent
registration area management of the UE.
If the Global RAN Node ID IE is included in the RAN CONFIGURATION UPDATE message, the AMF shall associate
the TNLA to the NG-C interface instance using the Global RAN Node ID.
ETSI
Figure 8.7.2.3-1: RAN configuration update: unsuccessful operation
If the AMF cannot accept the update, it shall respond with a RAN CONFIGURATION UPDATE FAILURE message
and appropriate cause value.

If the NG-RAN node, after initiating the RAN Configuration Update procedure, receives neither a RAN
CONFIGURATION UPDATE ACKOWLEDGE nor a RAN CONFIGURATION UPDATE FAILURE message, the
NG-RAN node may reinitiate a further RAN Configuration Update procedure towards the same AMF, provided that the
content of the new RAN CONFIGURATION UPDATE message is identical to the content of the previously
unacknowledged RAN CONFIGURATION UPDATE message.
8.7.3 AMF Configuration Update
8.7.3.1 General
The purpose of the AMF Configuration Update procedure is to update application level configuration data needed for
the NG-RAN node and AMF to interoperate correctly on the NG-C interface. This procedure does not affect existing
UE-related contexts, if any.
Figure 8.7.3.2-1: AMF configuration update: successful operation
The AMF initiates the procedure by sending an AMF CONFIGURATION UPDATE message including the appropriate
updated configuration data to the NG-RAN node. The NG-RAN node responds with an AMF CONFIGURATION
UPDATE ACKNOWLEDGE message to acknowledge that it successfully updated the configuration data. If an
information element is not included in the AMF CONFIGURATION UPDATE message, the NG-RAN node shall
interpret that the corresponding configuration data is not changed and shall continue to operate the NG-C interface with
the existing related configuration data.
If the PLMN Support List IE is included in the AMF CONFIGURATION UPDATE message, the NG-RAN node shall
overwrite the whole list of supported PLMN Identities and the corresponding list of AMF slices for each PLMN
Identity and use the received values for further network slice selection and AMF selection.
ETSI
If the AMF TNL Association to Add List IE is included in the AMF CONFIGURATION UPDATE message, the NG-
RAN node shall, if supported, use it to establish the TNL association(s) with the AMF. The NG-RAN node shall report
to the AMF, in the AMF CONFIGURATION UPDATE ACKNOWLEDGE message, the successful establishment of
the TNL association(s) with the AMF as follows:
- A list of successfully established TNL associations shall be included in the AMF TNL Association Setup List IE;
- A list of TNL associations that failed to be established shall be included in the AMF TNL Association Failed to
Setup List IE.
If the AMF TNL Association to Remove List IE is included in the AMF CONFIGURATION UPDATE message the NG-
RAN node shall, if supported, initiate removal of the TNL association(s) indicated by the received AMF Transport
Layer information towards the AMF.
If the AMF Name IE is included in the AMF CONFIGURATION UPDATE message, the NG-RAN node shall
overwrite the previously stored AMF name and use it to identify the AMF.
If the Served GUAMI List IE is included in the AMF CONFIGURATION UPDATE message, the NG-RAN node shall
overwrite the whole list of GUAMIs served by the AMF by the new list and use the received values for further AMF
management as defined in TS 23.501 [9].
If the Relative AMF Capacity IE is included in the AMF CONFIGURATION UPDATE message, the NG-RAN node
may use it as defined in TS 23.501 [9].
If the AMF TNL Association to Update List IE is included in the AMF CONFIGURATION UPDATE message the NG-
RAN node shall, if supported, update the TNL association(s) indicated by the received AMF Transport Layer
information towards the AMF.
If the TNL Association Usage IE or the TNL Address Weight Factor IE is included in the AMF TNL Association to Add
List IE or the AMF TNL Association to Update List IE, the NG-RAN node shall, if supported, consider it as defined in
TS 23.502 [10].
Figure 8.7.3.3-1: AMF configuration update: unsuccessful operation
If the NG-RAN node cannot accept the update, it shall respond with an AMF CONFIGURATION UPDATE FAILURE
message and appropriate cause value.

If the AMF receives neither an AMF CONFIGURATION UPDATE ACKOWLEDGE nor an AMF
CONFIGURATION UPDATE FAILURE message, the AMF may reinitiate the AMF Configuration Update procedure
towards the same NG-RAN node provided that the content of the new AMF CONFIGURATION UPDATE message is
identical to the content of the previously unacknowledged AMF CONFIGURATION UPDATE message.

8.7.4 NG Reset
8.7.4.1 General
The purpose of the NG Reset procedure is to initialise or re-initialise the RAN, or part of RAN NGAP UE-related
contexts, in the event of a failure in the 5GC or vice versa. This procedure does not affect the application level
configuration data exchanged during, e.g., the NG Setup procedure. The procedure uses non-UE associated signalling.
8.7.4.2.1 NG Reset initiated by the AMF
Figure 8.7.4.2.1-1: NG reset initiated by the AMF: successful operation
In the event of a failure at the AMF which has resulted in the loss of some or all transaction reference information, an
NG RESET message shall be sent to the NG-RAN node.
At reception of the NG RESET message the NG-RAN node shall release all allocated resources on NG and Uu related
to the UE association(s) indicated explicitly or implicitly in the NG RESET message and remove the indicated UE
contexts including NGAP ID.
After the NG-RAN node has released all assigned NG resources and the UE NGAP IDs for all indicated UE
associations which can be used for new UE-associated logical NG-connections over the NG interface, the NG-RAN
node shall respond with the NG RESET ACKNOWLEDGE message. The NG-RAN node does not need to wait for the
release of radio resources to be completed before returning the NG RESET ACKNOWLEDGE message.
If the NG RESET message contains the UE-associated Logical NG-connection List IE, then:
- The NG-RAN node shall use the AMF UE NGAP ID IE and/or the RAN UE NGAP ID IE to explicitly identify
the UE association(s) to be reset.
- The NG-RAN node shall include in the NG RESET ACKNOWLEDGE message, for each UE association to be
reset, the UE-associated Logical NG-connection Item IE in the UE-associated Logical NG-connection List IE.
The UE-associated Logical NG-connection Item IEs shall be in the same order as received in the NG RESET
message and shall include also unknown UE-associated logical NG-connections. Empty UE-associated Logical
NG-connection Item IEs, received in the NG RESET message, may be omitted in the NG RESET

by the Message Identifier and Serial Number IE is ongoing in an area indicated within the Warning Area List IE, the
NG-RAN node shall stop broadcasting the warning message within that area and discard the warning message for that
area.
If the Warning Area List IE is not included in the PWS CANCEL REQUEST message, the NG-RAN node shall stop
broadcasting and discard the warning message identified by the Message Identifier IE and the Serial Number IE in all of
the cells in the NG-RAN node.
The NG-RAN node shall acknowledge the PWS CANCEL REQUEST message by sending the PWS CANCEL
RESPONSE message, with the Message Identifier IE and the Serial Number IE copied from the PWS CANCEL
REQUEST message and shall, if there is an area to report where an ongoing broadcast was stopped successfully,
include the Broadcast Cancelled Area List IE.
If an area included in the Warning Area List IE in the PWS CANCEL REQUEST message does not appear in the
Broadcast Cancelled Area List IE, the AMF shall consider that the NG-RAN node had no ongoing broadcast to stop for
the same Message Identifier and Serial Number in that area.
If the Broadcast Cancelled Area List IE is not included in the PWS CANCEL RESPONSE message, the AMF shall
consider that the NG-RAN node had no ongoing broadcast to stop for the same Message Identifier and Serial Number.
If the Cancel-All Warning Messages Indicator IE is present in the PWS CANCEL REQUEST message, then the NG-
RAN node shall stop broadcasting and discard all warning messages for the area as indicated in the Warning Area List
IE or in all the cells of the NG-RAN node if the Warning Area List IE is not included. The NG-RAN node shall
acknowledge the PWS CANCEL REQUEST message by sending the PWS CANCEL RESPONSE message, with the

indicate that the related capability is missing. On the other hand, "not available" cause values indicate that the related
capability is present, but insufficient resources were available to perform the requested action.
ETSI
Radio Network Layer cause Meaning

Unspecified Sent for radio network layer cause when none of the specified cause values
applies.
TXnRELOCOverall expiry The timer guarding the handover that takes place over Xn has abnormally
expired.
Successful handover Successful handover.
Release due to NG-RAN generated Release is initiated due to NG-RAN generated reason.
reason
Release due to 5GC generated Release is initiated due to 5GC generated reason.
reason
Handover cancelled The reason for the action is cancellation of Handover.
Partial handover Provides a reason for the handover cancellation. The HANDOVER COMMAND
message from AMF contained PDU Session Resource to Release List IE or QoS
flow to Release List and the source NG-RAN node estimated service continuity
for the UE would be better by not proceeding with handover towards this
particular target NG-RAN node.
Handover failure in target 5GC/ NG- The handover failed due to a failure in target 5GC/NG-RAN node or target
RAN node or target system system.
Handover target not allowed Handover to the indicated target cell is not allowed for the UE in question.
TNGRELOCoverall expiry The reason for the action is expiry of timer TNGRELOCoverall.
TNGRELOCprep expiry Handover Preparation procedure is cancelled when timer TNGRELOCprep expires.
Cell not available The concerned cell is not available.
Unknown target ID Handover rejected because the target ID is not known to the AMF.
No radio resources available in Load on target cell is too high.
target cell
Unknown local UE NGAP ID The action failed because the receiving node does not recognise the local UE
NGAP ID.
Inconsistent remote UE NGAP ID The action failed because the receiving node considers that the received remote
UE NGAP ID is inconsistent.
Handover desirable for radio The reason for requesting handover is radio related.
reasons
Time critical handover Handover is requested for time critical reason i.e., this cause value is reserved to
represent all critical cases where the connection is likely to be dropped if
handover is not performed.
Resource optimisation handover The reason for requesting handover is to improve the load distribution with the
neighbour cells.
Reduce load in serving cell Load on serving cell needs to be reduced. When applied to handover
preparation, it indicates the handover is triggered due to load balancing.
User inactivity The action is requested due to user inactivity on all PDU sessions, e.g., NG is
requested to be released in order to optimise the radio resources.
Radio connection with UE lost The action is requested due to losing the radio connection to the UE.
Radio resources not available No requested radio resources are available.
Invalid QoS combination The action was failed because of invalid QoS combination.
Failure in the radio interface Radio interface procedure has failed.
procedure
Interaction with other procedure The action is due to an ongoing interaction with another procedure.
Unknown PDU Session ID The action failed because the PDU Session ID is unknown in the NG-RAN node.
Unknown QoS Flow ID The action failed because the QoS Flow ID is unknown in the NG-RAN node.
Multiple PDU Session ID instances The action failed because multiple instance of the same PDU Session had been
provided to the NG-RAN node.
Multiple QoS Flow ID instances The action failed because multiple instances of the same QoS flow had been
provided to the NG-RAN node.
Encryption and/or integrity protection The NG-RAN node is unable to support any of the encryption and/or integrity
algorithms not supported protection algorithms supported by the UE.
NG intra-system handover triggered The action is due to a NG intra-system handover that has been triggered.
NG inter-system handover triggered The action is due to a NG inter-system handover that has been triggered.
Xn handover triggered The action is due to an Xn handover that has been triggered.
Not supported 5QI value The QoS flow setup failed because the requested 5QI is not supported.
UE context transfer The action is due to a UE resumes from the NG-RAN node different from the one
which sent the UE into RRC_INACTIVE state.
IMS voice EPS fallback or RAT The setup of QoS flow is failed due to EPS fallback or RAT fallback for IMS voice
fallback triggered using handover or redirection.
UP integrity protection not possible The PDU session cannot be accepted according to the required user plane
integrity protection policy.
UP confidentiality protection not The PDU session cannot be accepted according to the required user plane
possible confidentiality protection policy.
Slice(s) not supported Slice(s) not supported.
ETSI
UE in RRC_INACTIVE state not The action is requested due to RAN paging failure.
reachable
Redirection The release is requested due to inter-system redirection or intra-system
redirection.
Resources not available for the The requested resources are not available for the slice(s).
slice(s)
UE maximum integrity protected The request is not accepted in order to comply with the maximum data rate for
data rate reason integrity protection supported by the UE.
Release due to CN-detected mobility The context release is requested by the AMF because the UE is already served
by another CN node (same or different system), or another NG interface of the
same CN node.
N26 interface not available The receiver shall consider that the action failed due to a temporary failure of the
N26 interface.
Release due to pre-emption Release is initiated due to pre-emption.

9.4 Message and Information Element Abstract Syntax (with

ASN.1)
9.4.1 General
NGAP ASN.1 definition conforms to ITU-T Rec. X.691 [4], ITU-T Rec. X.680 [5] and ITU-T Rec. X.681 [6].
The ASN.1 definition specifies the structure and content of NGAP messages. NGAP messages can contain any IEs
specified in the object set definitions for that message without the order or number of occurrence being restricted by
ASN.1. However, for this version of the standard, a sending entity shall construct an NGAP message according to the
PDU definitions module and with the following additional rules:
- IEs shall be ordered (in an IE container) in the order they appear in object set definitions.
- Object set definitions specify how many times IEs may appear. An IE shall appear exactly once if the presence
field in an object has value "mandatory". An IE may appear at most once if the presence field in an object has
value "optional" or "conditional". If in a tabular format there is multiplicity specified for an IE (i.e., an IE list)
then in the corresponding ASN.1 definition the list definition is separated into two parts. The first part defines an
IE container list where the list elements reside. The second part defines list elements. The IE container list
appears as an IE of its own. For this version of the standard an IE container list may contain only one kind of list
elements.
NOTE: In the above "IE" means an IE in the object set with an explicit ID. If one IE needs to appear more than
once in one object set, then the different occurrences will have different IE IDs.
If an NGAP message that is not constructed as defined above is received, this shall be considered as Abstract Syntax
Error, and the message shall be handled as defined for Abstract Syntax Error in subclause 10.3.6.
9.4.2 Usage of private message mechanism for non-standard use

The private message mechanism for non-standard use may be used:
- for special operator- (and/or vendor) specific features considered not to be part of the basic functionality, i.e., the
functionality required for a complete and high-quality specification in order to guarantee multivendor
interoperability;
- by vendors for research purposes, e.g., to implement and evaluate new algorithms/features before such features
are proposed for standardisation.
The private message mechanism shall not be used for basic functionality. Such functionality shall be standardised.

10 Handling of Unknown, Unforeseen and Erroneous

Protocol Data
10.1 General
Protocol Error cases can be divided into three classes:
- Transfer Syntax Error.
- Abstract Syntax Error.
- Logical Error.
Protocol errors can occur in the following functions within a receiving node:
NGAP
functional Logical Errors
entity
Abstract Syntax Errors
ASN.1 Decoding Transfer Syntax Errors
Figure 10.1-1: Protocol Errors in NGAP.
The information stated in subclauses 10.2, 10.3 and 10.4, to be included in the message used when reporting an error, is
what at minimum shall be included. Other optional information elements within the message may also be included, if
available. This is also valid for the case when the reporting is done with a response message. The latter is an exception
to what is stated in subclause 4.1.
10.2 Transfer Syntax Error

A Transfer Syntax Error occurs when the receiver is not able to decode the received physical message. Transfer syntax
errors are always detected in the process of ASN.1 decoding. If a Transfer Syntax Error occurs, the receiver should
initiate Error Indication procedure with appropriate cause value for the Transfer Syntax protocol error.
Examples for Transfer Syntax Errors are:
- Violation of value ranges in ASN.1 definition of messages. E.g., if an IE has a defined value range of 0 to 10
(ASN.1: INTEGER (0..10)), and 12 will be received, then this will be treated as a transfer syntax error.
- Violation in list element constraints. E.g., if a list is defined as containing 1 to 10 elements, and 12 elements will
be received, then this case will be handled as a transfer syntax error.
- Missing mandatory elements in ASN.1 SEQUENCE definitions (as sent by the originator of the message).
- Wrong order of elements in ASN.1 SEQUENCE definitions (as sent by the originator of the message).
10.3 Abstract Syntax Error

10.3.1 General
An Abstract Syntax Error occurs when the receiving functional NGAP entity:
1. receives IEs or IE groups that cannot be understood (unknown IE ID);
ETSI
2. receives IEs for which the logical range is violated (e.g., ASN.1 definition: 0 to 15, the logical range is 0 to 10,
while values 11 to 15 are undefined), and 12 will be received; this case will be handled as an abstract syntax
error using criticality information sent by the originator of the message);
3. does not receive IEs or IE groups but according to the specified presence of the concerning object, the IEs or IE
groups should have been present in the received message.
4. receives IEs or IE groups that are defined to be part of that message in wrong order or with too many
occurrences of the same IE or IE group;
5. receives IEs or IE groups but according to the conditional presence of the concerning object and the specified
condition, the IEs or IE groups should not have been present in the received message.
Cases 1 and 2 (not comprehended IE/IE group) are handled based on received Criticality information. Case 3 (missing
IE/IE group) is handled based on Criticality information and Presence information for the missing IE/IE group specified
in the version of the specification used by the receiver. Case 4 (IEs or IE groups in wrong order or with too many
occurrences) and Case 5 (erroneously present conditional IEs or IE groups) result in rejecting the procedure.
If an Abstract Syntax Error occurs, the receiver shall read the remaining message and shall then for each detected
Abstract Syntax Error that belong to cases 1-3 act according to the Criticality Information and Presence Information for
the IE/IE group due to which Abstract Syntax Error occurred in accordance with subclauses 10.3.4 and 10.3.5. The
handling of cases 4 and 5 is specified in subclause 10.3.6.
10.3.2 Criticality Information

In the NGAP messages there is criticality information set for individual IEs and/or IE groups. This criticality
information instructs the receiver how to act when receiving an IE or an IE group that is not comprehended, i.e., the
entire item (IE or IE group) which is not (fully or partially) comprehended shall be treated in accordance with its own
criticality information as specified in subclause 10.3.4.
In addition, the criticality information is used in case of the missing IE/IE group abstract syntax error (see subclause
10.3.5).
The receiving node shall take different actions depending on the value of the Criticality Information. The three possible
values of the Criticality Information for an IE/IE group are:
- Reject IE.
- Ignore IE and Notify Sender.
- Ignore IE.
The following rules restrict when a receiving entity may consider an IE, an IE group, or an EP not comprehended (not
implemented), and when action based on criticality information is applicable:
1. IE or IE group: When one new or modified IE or IE group is implemented for one EP from a standard version,
then other new or modified IEs or IE groups specified for that EP in that standard version shall be considered
comprehended by a receiving entity (some may still remain unsupported).
2. EP: The comprehension of different EPs within a standard version or between different standard versions is not
mandated. Any EP that is not supported may be considered not comprehended, even if another EP from that
standard version is comprehended, and action based on criticality shall be applied.
10.3.3 Presence Information

For many IEs/IE groups which are optional according to the ASN.1 transfer syntax, NGAP specifies separately if the
presence of these IEs/IE groups is optional or mandatory with respect to RNS application by means of the presence field
of the concerning object of class NGAP-PROTOCOL-IES, NGAP-PROTOCOL-IES-PAIR, NGAP-PROTOCOL-
EXTENSION or NGAP-PRIVATE-IES.
The presence field of the indicated classes supports three values:
1. Optional;
ETSI
2. Conditional;
3. Mandatory.
If an IE/IE group is not included in a received message and the presence of the IE/IE group is mandatory or the
presence is conditional and the condition is true according to the version of the specification used by the receiver, an
abstract syntax error occurs due to a missing IE/IE group.
If an IE/IE group is included in a received message and the presence of the IE/IE group is conditional and the condition
is false according to the version of the specification used by the receiver, an abstract syntax error occurs due to this
erroneously present conditional IE/IE group.
10.3.4 Not comprehended IE/IE group
10.3.4.1 Procedure Code

The receiving node shall treat the different types of received criticality information of the Procedure Code IE according
to the following:
Reject IE:
- If a message is received with a Procedure Code IE marked with "Reject IE" which the receiving node does not
comprehend, the receiving node shall reject the procedure using the Error Indication procedure.
Ignore IE and Notify Sender:
- If a message is received with a Procedure Code IE marked with "Ignore IE and Notify Sender" which the
receiving node does not comprehend, the receiving node shall ignore the procedure and initiate the Error
Indication procedure.
Ignore IE:
- If a message is received with a Procedure Code IE marked with "Ignore IE" which the receiving node does not
comprehend, the receiving node shall ignore the procedure.
When using the Error Indication procedure to reject a procedure or to report an ignored procedure it shall include the
Procedure Code IE, the Triggering Message IE, and the Procedure Criticality IE in the Criticality Diagnostics IE.
10.3.4.1A Type of Message

When the receiving node cannot decode the Type of Message IE, the Error Indication procedure shall be initiated with
an appropriate cause value.
10.3.4.2 IEs other than the Procedure Code and Type of Message
The receiving node shall treat the different types of received criticality information of an IE/IE group other than the
Procedure Code IE and Type of Message IE according to the following:
Reject IE:
- If a message initiating a procedure is received containing one or more IEs/IE group marked with "Reject IE"
which the receiving node does not comprehend; none of the functional requests of the message shall be executed.
The receiving node shall reject the procedure and report the rejection of one or more IEs/IE group using the
message normally used to report unsuccessful outcome of the procedure. In case the information received in the
initiating message was insufficient to determine a value for all IEs that are required to be present in the message
used to report the unsuccessful outcome of the procedure, the receiving node shall instead terminate the
procedure and initiate the Error Indication procedure.
- If a message initiating a procedure that does not have a message to report unsuccessful outcome is received
containing one or more IEs/IE groups marked with "Reject IE" which the receiving node does not comprehend,
the receiving node shall terminate the procedure and initiate the Error Indication procedure.
ETSI
- If a response message is received containing one or more IEs marked with "Reject IE", that the receiving node
does not comprehend, the receiving node shall consider the procedure as unsuccessfully terminated and initiate
local error handling.
- If a message initiating a procedure is received containing one or more IEs/IE groups marked with "Ignore IE and
Notify Sender" which the receiving node does not comprehend, the receiving node shall ignore the content of the
not comprehended IEs/IE groups, continue with the procedure as if the not comprehended IEs/IE groups were
not received (except for the reporting) using the understood IEs/IE groups, and report in the response message of
the procedure that one or more IEs/IE groups have been ignored. In case the information received in the
initiating message was insufficient to determine a value for all IEs that are required to be present in the response
message, the receiving node shall instead terminate the procedure and initiate the Error Indication procedure.
- if a message initiating a procedure that does not have a message to report the outcome of the procedure is
received containing one or more IEs/IE groups marked with "Ignore IE and Notify Sender" which the receiving
node does not comprehend, the receiving node shall ignore the content of the not comprehended IEs/IE groups,
continue with the procedure as if the not comprehended IEs/IE groups were not received (except for the
reporting) using the understood IEs/IE groups, and initiate the Error Indication procedure to report that one or
more IEs/IE groups have been ignored.
- If a response message is received containing one or more IEs/IE groups marked with "Ignore IE and Notify
Sender" which the receiving node does not comprehend, the receiving node shall ignore the content of the not
comprehended IEs/IE groups, continue with the procedure as if the not comprehended IEs/IE groups were not
received (except for the reporting) using the understood IEs/IE groups and initiate the Error Indication
procedure.
Ignore IE:
- If a message initiating a procedure is received containing one or more IEs/IE groups marked with "Ignore IE"
which the receiving node does not comprehend, the receiving node shall ignore the content of the not
comprehended IEs/IE groups and continue with the procedure as if the not comprehended IEs/IE groups were
not received using the understood IEs/IE groups.
- If a response message is received containing one or more IEs/IE groups marked with "Ignore IE" which the
receiving node does not comprehend, the receiving node shall ignore the content of the not comprehended IEs/IE
groups and continue with the procedure as if the not comprehended IEs/IE groups were not received using the
understood IEs/IE groups.
When reporting not comprehended IEs/IE groups marked with "Reject IE" or "Ignore IE and Notify Sender" using a
response message defined for the procedure, the Information Element Criticality Diagnostics IE shall be included in the
Criticality Diagnostics IE for each reported IE/IE group.
When reporting not comprehended IEs/IE groups marked with "Reject IE" or "Ignore IE and Notify Sender" using the
Error Indication procedure, the Procedure Code IE, the Triggering Message IE, Procedure Criticality IE, and the
Information Element Criticality Diagnostics IE shall be included in the Criticality Diagnostics IE for each reported
IE/IE group.
10.3.5 Missing IE or IE group

The receiving node shall treat the missing IE/IE group according to the criticality information for the missing IE/IE
group in the received message specified in the version of this specification used by the receiver:
Reject IE:
- if a received message initiating a procedure is missing one or more IEs/IE groups with specified criticality
"Reject IE"; none of the functional requests of the message shall be executed. The receiving node shall reject the
procedure and report the missing IEs/IE groups using the message normally used to report unsuccessful outcome
of the procedure. In case the information received in the initiating message was insufficient to determine a value
for all IEs that are required to be present in the message used to report the unsuccessful outcome of the
procedure, the receiving node shall instead terminate the procedure and initiate the Error Indication procedure.
ETSI
- if a received message initiating a procedure that does not have a message to report unsuccessful outcome is
missing one or more IEs/IE groups with specified criticality "Reject IE", the receiving node shall terminate the
procedure and initiate the Error Indication procedure.
- if a received response message is missing one or more IEs/IE groups with specified criticality "Reject IE, the
receiving node shall consider the procedure as unsuccessfully terminated and initiate local error handling.
"Ignore IE and Notify Sender", the receiving node shall ignore that those IEs are missing and continue with the
procedure based on the other IEs/IE groups present in the message and report in the response message of the
procedure that one or more IEs/IE groups were missing. In case the information received in the initiating
message was insufficient to determine a value for all IEs that are required to be present in the response message,
the receiving node shall instead terminate the procedure and initiate the Error Indication procedure.
- if a received message initiating a procedure that does not have a message to report the outcome of the procedure
is missing one or more IEs/IE groups with specified criticality "Ignore IE and Notify Sender", the receiving node
shall ignore that those IEs are missing and continue with the procedure based on the other IEs/IE groups present
in the message and initiate the Error Indication procedure to report that one or more IEs/IE groups were missing.
- if a received response message is missing one or more IEs/IE groups with specified criticality "Ignore IE and
Notify Sender", the receiving node shall ignore that those IEs are missing and continue with the procedure based
on the other IEs/IE groups present in the message and initiate the Error Indication procedure to report that one or
more IEs/IE groups were missing.
Ignore IE:
"Ignore IE", the receiving node shall ignore that those IEs are missing and continue with the procedure based on
the other IEs/IE groups present in the message.
- if a received response message is missing one or more IEs/IE groups with specified criticality "Ignore IE", the
receiving node shall ignore that those IEs/IE groups are missing and continue with the procedure based on the
other IEs/IE groups present in the message.
When reporting missing IEs/IE groups with specified criticality "Reject IE" or "Ignore IE and Notify Sender" using a
response message defined for the procedure, the Information Element Criticality Diagnostics IE shall be included in the
Criticality Diagnostics IE for each reported IE/IE group.
When reporting missing IEs/IE groups with specified criticality "Reject IE" or "Ignore IE and Notify Sender" using the
Error Indication procedure, the Procedure Code IE, the Triggering Message IE, Procedure Criticality IE, and the
Information Element Criticality Diagnostics IE shall be included in the Criticality Diagnostics IE for each reported
IE/IE group.
10.3.6 IEs or IE groups received in wrong order or with too many

occurrences or erroneously present
If a message with IEs or IE groups in wrong order or with too many occurrences is received or if IEs or IE groups with
a conditional presence are present when the condition is not met (i.e., erroneously present), the receiving node shall
behave according to the following:
- If a message initiating a procedure is received containing IEs or IE groups in wrong order or with too many
occurrences or erroneously present, none of the functional requests of the message shall be executed. The
receiving node shall reject the procedure and report the cause value "Abstract Syntax Error (Falsely Constructed
Message)" using the message normally used to report unsuccessful outcome of the procedure. In case the
information received in the initiating message was insufficient to determine a value for all IEs that are required
to be present in the message used to report the unsuccessful outcome of the procedure, the receiving node shall
instead terminate the procedure and initiate the Error Indication procedure.
- If a message initiating a procedure that does not have a message to report unsuccessful outcome is received
containing IEs or IE groups in wrong order or with too many occurrences or erroneously present, the receiving
ETSI
node shall terminate the procedure and initiate the Error Indication procedure, and use cause value "Abstract
Syntax Error (Falsely Constructed Message)".
- If a response message is received containing IEs or IE groups in wrong order or with too many occurrences or
erroneously present, the receiving node shall consider the procedure as unsuccessfully terminated and initiate
local error handling.
When determining the correct order only the IEs specified in the specification version used by the receiver shall be
considered.
10.4 Logical Error

Logical error situations occur when a message is comprehended correctly, but the information contained within the
message is not valid (i.e., semantic error), or describes a procedure which is not compatible with the state of the
receiver. In these conditions, the following behaviour shall be performed (unless otherwise specified) as defined by the
class of the elementary procedure, irrespective of the criticality information of the IEs/IE groups containing the
erroneous values.
Class 1:
Where the logical error occurs in a request message of a class 1 procedure, and the procedure has a message to report
this unsuccessful outcome, this message shall be sent with an appropriate cause value. Typical cause values are:
- Semantic Error.
- Message not compatible with receiver state.
Where the logical error is contained in a request message of a class 1 procedure, and the procedure does not have a
message to report this unsuccessful outcome, the procedure shall be terminated and the Error Indication procedure shall
be initiated with an appropriate cause value. The Procedure Code IE and the Triggering Message IE within the
Criticality Diagnostics IE shall then be included in order to identify the message containing the logical error.
Where the logical error exists in a response message of a class 1 procedure, the procedure shall be considered as
unsuccessfully terminated and local error handling shall be initiated.
Class 2:
Where the logical error occurs in a message of a class 2 procedure, the procedure shall be terminated and the Error
Indication procedure shall be initiated with an appropriate cause value. The Procedure Code IE and the Triggering
Message IE within the Criticality Diagnostics IE shall then be included in order to identify the message containing the
logical error.
10.5 Exceptions
The error handling for all the cases described hereafter shall take precedence over any other error handling described in
the other subclauses of clause 10.
- If any type of error (Transfer Syntax Error, Abstract Syntax Error or Logical Error) is detected in the ERROR
INDICATION message, it shall not trigger the Error Indication procedure in the receiving Node but local error
handling.
- In case a response message or Error Indication message needs to be returned, but the information necessary to
determine the receiver of that message is missing, the procedure shall be considered as unsuccessfully terminated
and local error handling shall be initiated.
- If an error that terminates a procedure occurs, the returned cause value shall reflect the error that caused the
termination of the procedure even if one or more abstract syntax errors with criticality "ignore and notify" have
earlier occurred within the same procedure.
- If an AP ID error is detected, the error handling as described in subclause 10.6 shall be applied.
ETSI
10.6 Handling of AP ID
NOTE: The "first message", the "first returned message" and the "last message" as used below correspond to
messages for a UE-associated logical connection. The "first message" has a new AP ID from the sending
node and the "first returned message" is the first response message, which has a new AP ID from the node
sending the "first returned message". Thereafter the two AP IDs are included in all messages over the UE-
associated logical connection unless otherwise allowed by the specification. The "last message" is a
message sent by a node in order to complete the termination of a given UE-associated logical connection,
such that no other messages for the same connection are expected in either direction. The nodes should
ensure as far as possible that previously allocated AP ID are not immediately reused.
If a node receives a first returned message that includes an unknown local AP ID, the receiving node shall initiate an
Error Indication procedure with inclusion of the received AP IDs from the peer node and an appropriate cause value.
Both nodes shall initiate a local release of any established UE-associated logical connection (for the same NG interface)
having these AP IDs as local or remote identifier.
If a node receives a message (other than the first or first returned messages) including an erroneous AP ID that is either
an unknown local AP ID, or an inconsistent remote AP ID (i.e. it is different to the remote AP ID stored previously for
this UE-associated logical connection) for the same NG interface:
- if this message is not the last message for this UE-associated logical connection, the node shall initiate an Error
Indication procedure with inclusion of the received AP ID(s) from the peer node and an appropriate cause value.
Both nodes shall initiate a local release of any established UE-associated logical connection (for the same NG
interface) having the erroneous AP ID as either the local or remote identifier.
- if this message is the last message for this UE-associated logical connection, the receiving node shall initiate a
local release of any established UE-associated logical connection (for the same NG interface) having the
erroneous AP ID as either the local or remote identifier.
