Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method, device, and system for signaling transmission in a combined service.
Background
Two interfaces exist in UMTS (Universal Mobile Telecommunications System), which are a Uu interface between a UE (User Equipment) and a UTRAN (Universal terrestrial Radio Access Network) and an Iu interface between a CN (Core Network) and the UTRAN, respectively. Two interfaces also exist in the UTRAN, which are an Iub interface between a NodeB (base station) and an RNC (Radio Network Controller), and an Iur interface between an RNC and an RNC. Protocols on different interfaces are divided into User-Plane protocols, which manage the formatting for transmitting information, and Control-Plane protocols, which manage the transmission of Control signaling and maintain the connection between the UE and the CN.
In the UMTS system, the network side and the UE complete the interaction of user plane data and control plane signaling through an RB (Radio Bearer). The network side and the UE perform RRC (Radio Resource Control) signaling interaction through an SRB (signaling Radio Bearer), and complete user plane data interaction through an RB. Currently, there are SRBs defined in the protocol as SRB0, SRB1, SRB2, SRB3, and SRB 4.
Services established by the UE can be divided into CS (Circuit Stream) services and PS (Packet Stream) services according to the core network layer, QoS (Quality of service) of the two types of services has different requirements, and the CS services are generally considered to include voice services, streaming services and the like, and these services have lower speed, but higher real-time performance and are more sensitive to delay; the PS service includes a download service, a background service, an interactive service, etc., and the service has a high rate and a relatively low delay requirement. When initiating CS service, the UE must be configured in CELL _ DCH state, and when initiating PS service, the UE may be configured in CELL _ DCH state or CELL _ FACH state.
Once the idle UE has a CS service and/or a PS service requirement, it first needs to initiate an RRC connection process, and after completing the establishment of the RRC connection, it can establish an SRB and a corresponding service RB between the UE and the network side for transmitting different services. On the premise that the UE has established RRC connection and initiated CS and/or PS services, SBR2 generally needs to carry the following control signaling: control signaling used in the signaling interaction process of RB reconfiguration, such as RB setup signaling, reconfiguration signaling, release signaling, and the like; control signaling used in the mobility measurement process, such as measurement control signaling, measurement report signaling, and the like; control signaling used in the active set update procedure, such as active set update signaling.
The inventor finds that when the UE initiates the CS service and the PS service simultaneously, it is easy to trigger the non-recoverable error of SRB2, at this time, the UE needs to be switched from the CELL _ DCH state to the CELL _ FACH state, and after all the dedicated link resources are released, the dedicated link is re-established and the service between the UE and the network side is attempted to be recovered by initiating the CELL update process through the common channel. This process generally requires several seconds, which causes a delay in the transmission of the CS service and the PS service, and even causes an interruption of the CS service and the PS service, which affects the timeliness and effectiveness of the service data, especially the transmission of the CS service.

when the network side equipment determines to transmit the control signaling to the UE, the SRB corresponding to the level is used for transmitting the control signaling according to the level of the control signaling;
wherein the dividing of the control signaling into N levels comprises: dividing the control signaling into three levels of control signaling for configuring a circuit switching stream (CS) service, control signaling for configuring a packet switching stream (PS) service and other control signaling;

when the control signaling is determined to be the control signaling for configuring the CS service, transmitting the control signaling through a first SRB;

Detailed Description
In the existing UMTS technology, different SRBs and RBs are distinguished by RB IDs (RB identity) in a protocol, and the range of the RB IDs in the protocol is 1 to 32 (excluding SRB 0). Wherein,
SRB0 (equivalent to RB0) belongs to a common signaling bearer, i.e., all UEs can share the bearer, which does not need to be configured between the network side and the UEs; SRBs 1-4 (equivalent to RB 1-4) belong to dedicated signaling bearers, occupy SRB bearer resources on the network side independently for each UE, and can be configured on the network side in the RRC connection establishment process or reconfiguration process. The functions of SRB0/SRB1/SRB2/SRB3/SRB4 are as follows:
SRB0 is used for all signaling over CCCH (Common Control logical Channel), where RLC (Radio Link Control) is operatively configured to: an uplink transparent transmission mode and a downlink non-confirmation mode;
SRB1 is used for all signaling on the DCCH (Dedicated Control logical Channel), where RLC operation is configured in unacknowledged mode;
SRB2 is used for all signaling on the DCCH, where RLC operation is configured in acknowledged mode;
SRB3 is used for all signaling on DCCH and signaling is used to carry NAS signaling, where RLC operation is configured in acknowledged mode;
SRB4 is used for all transmission UE INFORMATION RESPONSE signaling, optionally all signaling on DCCH, and signaling to carry NAS signaling, where RLC operation is configured in acknowledged mode.
For RB bearers with RB IDs between 5 and 32, which can be used for user plane data transmission, and also for all signaling on DCCH, the RLC operation is configured as transparent transmission mode when used for signaling transmission.
In the existing UMTS technology, if the UE sends the uplink RRC signaling, the RLC layer triggers the RLC reset procedure due to an abnormal transmission or the RLC packet transmission reaches the maximum number of retransmissions, and if the RLC reconfiguration number reaches the maximum number of resets, the RLC unrecoverable error is triggered.
The protocol defines that after RLC non-recoverable error occurs to UE, the UE needs to be switched from CELL _ DCH state to CELL _ FACH state, after all special link resources are released, a CELL updating process is initiated through a public channel to complete special link reconstruction and attempt to recover the previous service. This process generally requires several seconds, and if the UE initiates the CS service in the CELL _ DCH state before, the CS service may be delayed or even interrupted, which affects the timeliness and effectiveness of CS service transmission and greatly affects the user experience.
Once the idle UE has a CS service and/or a PS service requirement, it first needs to initiate an RRC connection process, and after completing the establishment of the RRC connection, it can establish an SRB between the UE and the network side and a corresponding service RB for transmitting different services. On the premise that the UE has established RRC connection and initiated CS and/or PS services, SBR2 generally needs to carry the following control signaling: signaling interaction procedures for RB reconfiguration, such as RB setup signaling, RB reconfiguration signaling, RB release signaling, and the like; the measurement process for mobility comprises measurement control and measurement reporting; for active set update procedures, such as active set update signaling, etc.; signaling for RRC connection management, such as RRC connection setup complete, RRC connection release request signaling, and the like.
As shown in fig. 1, when the UE initiates the CS service and the PS service simultaneously, that is, initiates the combinational service, according to the analysis above, the control signaling carried on the SRB2 mainly includes the control signaling listed in the following 1, 2, and 3, and since the control signaling carried on the SRB2 is excessive, the RLC unrecoverable error, that is, the unrecoverable error of the SRB2 is easily triggered.
1. The control signaling for configuring the CS service mainly includes: control signaling used in the signaling interaction process of RB configuration for carrying CS services, such as RB setup signaling, RB reconfiguration signaling, RB release signaling, and the like;
2. control signaling for configuring PS services, which mainly includes: control signaling used in the signaling interaction process of RB configuration for carrying PS services, such as RB setup signaling, RB reconfiguration signaling, RB release signaling, and the like;
3. other control signaling, including: control signaling related to access and mobility states, control signaling related to RRC connection establishment, and the like, where the control signaling related to access includes: control signaling used in the active set update procedure, such as active set update signaling; the mobility state related control signaling comprises: control signaling used in the mobility measurement process, such as measurement control signaling, measurement report signaling, and the like; the control signaling related to the RRC connection establishment comprises: control signaling used in the RRC connection establishment procedure, such as RRC connection establishment signaling.
Also, in the combined service, when the signaling is frequently sent due to power, coverage, and the like, it is easier to trigger a non-recoverable error of the SRB 2.
For example, a user is performing a CS service (e.g., making a call), and has completed a certain PS service (e.g., downloading an application), since the PS service is already finished, the network side needs to release resources corresponding to the PS, and according to the protocol specification, a PS RB release operation (the signaling is carried on the SRB2) needs to be performed at a Uu interface (interface between the UE and the network), and at this time, a failure of the UE sending an uplink RB release Complete (RBRelease Complete) signaling may occur, which may affect the CS service. Similarly, the network side may also detect that the downlink RRC signaling transmission fails, and at this time, the network side may directly release the RRC establishment of the UE or attempt to reestablish the corresponding SRB2, which also affects the CS service. Similarly, in the case of PS RB setup, reconfiguration or other signaling interaction only for PS RB operation, the CS service of the UE may also be affected.
In summary, in the combined service, since the control signaling for configuring the PS service and the CS service is carried on one SRB of SRBs 2, and the control signaling carried on SRB2 is too much, it is easy to trigger a non-recoverable error of SRB2, and it affects the timeliness and effectiveness of data transmission of the service initiated by the UE, especially the CS service.
Therefore, the embodiment of the present invention provides a signaling transmission method and apparatus under a combined service, where a control signaling only carried by SRB2 in the prior art is carried by at least two SRBs, so as to reduce overhead of the signaling carried on the SRBs, thereby reducing the possibility of non-recoverable errors occurring in the SRBs and improving timeliness and effectiveness of service transmission.
The following describes in detail the implementation of the signaling transmission method and apparatus under combinational service according to the embodiments of the present invention with reference to the accompanying drawings.
Fig. 2 is a first embodiment of a method for signaling transmission under a combined service according to the embodiment of the present invention, where the combined service includes: CS services and PS services; as shown in fig. 2, the method includes:
step 201: the network side equipment divides the control signaling into N levels and establishes a corresponding relation between the N levels and M SRBs, wherein M is more than or equal to 2 and less than or equal to N and less than or equal to 32, each level corresponds to one SRB in the corresponding relation, and each SRB corresponds to at least one level;
the control signaling in the embodiment of the present invention refers to control signaling carried on SRB2 in the prior art.
When the control signaling is classified, the control signaling may be classified according to the manners indicated in 1, 2, and 3, so that the control signaling is classified into: control signaling for configuring CS services, control signaling for configuring PS services, and other control signaling. The division of three levels according to the service corresponding to the control signaling is only an example, in practical applications, the control signaling may be divided into two levels, or four levels or more, and the specific number of levels and the division method are not limited herein.
Alternatively, the division may be performed according to the priority of the control signaling or other parameter information of the control signaling, which is not limited herein. For example, the priority levels of the control signaling are divided into a high priority level, a medium priority level and a low priority level, and each priority level corresponds to one SRB, so that the control signaling for configuring the CS service and the control signaling for configuring the PS service, which is higher in priority, can be carried on one SRB, other control signaling for configuring the CS service and other control signaling for configuring the PS service can be carried on another SRB as medium priority signaling, and the other control signaling can be carried on a third SRB as low priority control signaling, so that the transmission efficiency of the CS service can be further improved.
Step 202: when the network side equipment determines to transmit the control signaling to the UE, the SRB corresponding to the level is used for transmitting the control signaling according to the level of the control signaling.
In the signaling transmission method under the combined service shown in fig. 2, the control signaling originally carried by only one SRB of SRBs 2 is carried by M SRBs together, so that the possibility of SRB non-recoverable errors caused by too many control signaling carried by one SRB is reduced, and the timeliness and effectiveness of service transmission, especially CS service transmission, are improved.
On the basis of fig. 2, a method for signaling transmission under a combined service according to an embodiment of the present invention is described in more detail with reference to fig. 3, in which a control signaling is divided into three levels, i.e., a control signaling for configuring a CS service, a control signaling for configuring a PS service, and other control signaling; as shown in fig. 3, includes:
step 300: the network side equipment divides the control signaling into N levels, establishes a corresponding relation between the N levels and M SRBs, wherein M is more than or equal to 2 and is more than or equal to N and is less than or equal to 32, and the corresponding relation is as follows: each level corresponds to one SRB, and each SRB corresponds to at least one level.
In the embodiment of the present invention shown in fig. 3, N takes a value of 3, and M also takes a value of 3.
Step 301: when the network side equipment determines to transmit a control signaling to UE, the control signaling is transmitted through a first SRB when the control signaling is determined to be the control signaling for configuring the CS service according to the level of the control signaling; when the control signaling is determined to be the control signaling for configuring the CS service, the control signaling is transmitted through a second SRB; and when the control signaling is determined to be other control signaling, transmitting the control signaling through a third SRB.
Wherein in this step, M is determined to be 3, i.e. the three levels correspond to 3 different SRBs; in practical application, the control signaling may also include only the first SRB and the second SRB, and at this time, when it is determined in this step that the control signaling is another control signaling, the control signaling is transmitted through the first SRB, or the control signaling is transmitted through the second SRB.
The first SRB is SRB 2; and the other M-1 SRBs are newly established E-SRBs (Enhanced-Signalling Radio Bearer) or SRBs 1 or SRBs 3 or SRBs 4, and the RB ID of the newly established E-SRB is any numerical value between 5 and 32.
The newly established E-SRB in the embodiment of the invention refers to: and establishing the RB with the RB ID of 5-32 in the prior art as the SRB. When the RB ID of the SRB is 0 or 1 or 3 or 4, it means that the SRBs in the prior art are functionally extended, so that in the embodiment of the present invention, the SRBs implement transmission of the control signaling carried on the SRB2 in the prior art.
The method for establishing the E-SRB and the method for expanding the SRB1, SRB3, or SRB4 are described later with reference to fig. 4 and the corresponding description thereof, and are not described herein again.
Step 302: and the network side equipment receives the confirmation signaling corresponding to the control signaling fed back by the UE on the SRB sending the control signaling.
Based on the above embodiment, when the UE receives the control signaling transmitted by the network side device on the SRBs, the UE feeds back the acknowledgment signaling corresponding to the control signaling on the SRBs transmitting the control signaling, thereby ensuring high-reliability transmission of the control signaling on the M SRBs.
In the following, a method for establishing E-SRB in an embodiment of the present invention is described with reference to fig. 4, where the network side device is implemented by an RNC, where:
step 401: in the process of establishing RRC connection, UE indicates whether the UE supports the establishment of E-SRB to RNC;
specifically, the UE may carry indication information of whether the UE supports the establishment of the E-SRB in any uplink RRC signaling in the RRC connection establishment process, so as to indicate to the network side device whether the UE supports the establishment of the E-SRB through the indication information.
Step 402: and the RNC receives an instruction sent by the UE, selects at least one RB with the RB ID of 5-21 when determining that the UE supports the establishment of the E-SRB, and uses the selected RB to carry RRC signaling.
The selected logical channel corresponding to the RB is DCCH, and the corresponding RLC mode may be an RLC unacknowledged mode or an RLC acknowledged mode.
Step 403: and the RNC completes the configuration of the E-SRB between the RNC and the Node B.
The configuration information includes: configuration information carried by the E-SRB at the Iub interface, more specifically, resource information, code channel information, power information and the like correspondingly allocated to the E-SRB.
Preferably, the E-SRB may be carried on a DCH (Dedicated Channel), or may also be carried on a HS-DSCH (High Speed-Downlink Shared Channel), and/or an E-DCH (Enhanced Dedicated Channel), and the like, which is not limited herein.
Step 404: the RNC carries the E-SRB configuration information in the downlink RRC signaling.
Wherein, the E-SRBs that have been indicated to be configured in step 402 may be one or more, and the configuration information of each E-SRB mainly includes:
(1) RB ID; ranging from 5 to 32 (with reference to the prior art, RB0 to 4 has been used for SRB);
(2) RLC configuration information; the method mainly comprises the following steps: confirming mode RLC configuration information which mainly comprises RLC sending window size, timer configuration for sending reset RLC PDUs, and maximum reset PDU sending number; unacknowledged mode RLC configuration information mainly including an RLC discard mode;
(3) configuring the same RB ID as other RBs; for example, SRB1 is already configured, when RB 6 is configured to be E-SRB, and RLC configuration information of the E-SRB is the same as SRB1, when RB ID can be filled in to be 1;
(4) RB mapping information; the method mainly comprises the following steps: the uplink and downlink transmission channel types, the transmission channel IDs and the corresponding logic channel IDs; RLC PDU length mode, fixed length setting or flexible length setting.
Step 405: and configuring the rule of the E-SRB in the RNC and the UE.
The rule of the E-SRB may be preset in the RNC and the UE, or may be explicitly specified in a protocol or a standard, so that the transmission of the control signaling is performed according to the rule when the transmission of the control signaling is performed subsequently.
For example, the rules may include:
in the RRC connection establishment phase, the RNC directly establishes one or more SRBs 1-SRB4 (comprising SRB2) and E-SRBs;
if single service is configured, using corresponding rule in the prior art to transmit control signaling, at this time, E-SRB may not carry any control signaling;
if the combined service of CS and PS is configured, SRB2 is used for carrying control signaling for configuring the CS service, E-SRB carries control signaling for configuring the PS service and other control signaling, and the control signaling carried on other SRBs 0/SRBs 1/SRBs 2/SRBs 3/SRBs 4 is unchanged.
Step 406: the UE carries out E-SRB configuration according to the E-SRB configuration information, and when the E-SRB configuration is completed, the UE indicates the RNC that the E-SRB configuration is completed; and when the E-SRB configuration fails, the UE indicates the RNC that the E-SRB configuration fails.
The UE may carry the indication information of the completion of the E-SRB configuration in the uplink RRC signaling when sending the uplink RRC signaling to the RNC. For example, the uplink RRC signaling may be RRC establishment completion signaling, RB reconfiguration completion signaling, and the like.
When the UE fails to configure the E-SRB, the following two conditions are included:
(1) if the RNC requires only configuring the E-SRB, the UE can carry indication information of E-SRB configuration failure in control signaling such as RRC establishment failure, RB reconfiguration failure and the like, for example, RB ID of the E-SRB is carried in a certain preset field;
(2) if the RNC requires the configuration of one or more of SRB1-SRB4 (including SRB2) and E-SRB, two cases are distinguished:
if the other RB configuration besides the E-SRB also fails, the UE can carry the RB ID of the SRB with failed configuration in signaling such as RRC establishment failure signaling, RB establishment failure signaling or RB reconfiguration failure signaling;
if only the E-SRB configuration fails and the other SRBs configuration succeeds, the UE may carry the E-SRB configuration failure indication information in the signaling such as the RRC establishment completion signaling, the RB establishment completion signaling, or the RB reconfiguration completion signaling, for example, the RB ID of the E-SRB is carried in a certain preset field.
In addition, the method for expanding the original SRBs 1, SRBs 3, and SRBs 4 may refer to the method for establishing the E-SRBs described in fig. 4, which is not described herein again.
Corresponding to the signaling transmission method, an embodiment of the present invention further provides an apparatus for performing signaling transmission under a combined service, where as shown in fig. 5, the apparatus includes:
an establishing unit 510, configured to divide the control signaling into N levels, and establish a corresponding relationship between the N levels and M SRBs, where M is greater than or equal to 2 and is less than or equal to N and is less than or equal to 32, where the corresponding relationship is: each grade corresponds to one SRB, and each SRB corresponds to at least one grade;
a transmission unit 520, configured to determine, when transmitting the control signaling to the UE, according to the level of the control signaling, use the SRB corresponding to the level to transmit the control signaling.
Preferably, the control signaling can be divided into: control signaling for configuring CS service, control signaling for configuring PS service and other control signaling; at this time, the process of the present invention,
the establishing unit is specifically configured to: dividing the control signaling into three levels of control signaling for configuring CS service, control signaling for configuring PS service and other control signaling, and establishing corresponding relations between the three levels and M SRBs;
the transmission unit 520 may specifically be configured to: when the control signaling is determined to be the control signaling for configuring the CS service, the control signaling is transmitted through a first SRB; and when the control signaling is determined to be the control signaling for configuring the CS service, transmitting the control signaling through a second SRB.
Preferably, the transmission unit 520 may also be configured to: when the control signaling is determined to be other control signaling, transmitting the control signaling through a third SRB;
alternatively, the transmission unit 520 may also be configured to: and when the control signaling is determined to be other control signaling, transmitting the control signaling through a first SRB, or transmitting the control signaling through a second SRB.
