Abstract

The embodiment of the application provides a configuration method, a device, equipment and a readable storage medium, wherein the method comprises the following steps: receiving first configuration information, wherein the first configuration information comprises first information, and the first information indicates that the terminal is allowed to initiate a request for activating and/or deactivating a secondary node SN or a primary secondary cell PScell or a secondary cell group SCG, or is not allowed to initiate a request for activating and/or deactivating the SN or the PScell or the SCG.

Description

Configuration method, device, equipment and readable storage medium

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a configuration method, a device, equipment and a readable storage medium.

Background

In the dual-connection scenario, activation and deactivation of the secondary cell group (Secondary Cell Group, SCG) is a mechanism that can expedite the workflow of entering or removing dual-connections. Since the power consumption of the terminal is larger in the dual-connection state, after the Secondary Node (SN)/SCG is added, if the service rate of the terminal is reduced, the SN, the primary Secondary cell (Primary Secondary Cell, PSCell) or SCG can be in a deactivated or suspended or dormant (dormant) state, and the network side can maintain the context configuration information of the terminal instead of releasing the SN, PSCell or SCG. Therefore, the secondary station or the secondary cell group is deactivated, so that the power consumption of the terminal can be saved, and the service of the double connection can be quickly restored when the service rate of the UE is increased.

Currently, there is no explicit scheme for activation and deactivation of SN or PSell or SCG, triggered by network side MN or SN, or triggered by UE.

In addition, when the SCG is in the deactivated state, since the radio link between the UE and the SCG is not in a normal RRC connection state, and failure information of the PCell or the MCG cannot be fed back in time, the UE waits for a subsequent indication of the MCG for too long, and a new mechanism needs to be introduced to realize rapid MCG connection recovery.

Referring to fig. 2, an embodiment of the present application provides a configuration method, which is executed by a terminal and includes:

Step 201: first configuration information is received, the first configuration information comprising first information indicating that the terminal is allowed to initiate a request to activate and/or deactivate SN or PSCell or SCG, or is not allowed to initiate a request to activate and/or deactivate SN or PSCell or SCG.

In an embodiment of the present application, the first configuration information further includes one or more of the following:

(1) Second information indicating that the terminal initiates a request for activating and/or deactivating SN or PSCell or SCG to SN, or the terminal initiates a request for activating and/or deactivating SN or PSCell or SCG to a Master Node (MN);

(2) Third information, the third information indicating the terminal to initiate a first resource for activating an SN or PSCell or SCG request, the first resource comprising: resources of UL grant or dedicated random access resources.

(3) Fourth information indicating that the PCell or MCG connection is allowed to be quickly restored when the SCG is in a deactivated state;

In the embodiment of the present application, when the first configuration information includes fourth information, the first configuration information further includes: a detection parameter for detecting a radio link failure (radio link failure, RLF) of the PCell or MCG in the SCG deactivated state.

In an embodiment of the present application, the method further includes:

In the embodiment of the application, the terminal can flexibly activate or deactivate the SN or PSell or SCG.

Referring to fig. 3, an embodiment of the present application provides a configuration method, which is executed by a network side device, including:

step 301: transmitting first configuration information to a terminal, wherein the first configuration information comprises: first information indicating that the terminal is allowed to initiate a request to activate and/or deactivate SN or PSCell or SCG, or is not allowed to initiate a request to activate and/or deactivate SN or PSCell or SCG.

(1) Second information indicating that the terminal initiates a request to activate and/or deactivate SN or PSCell or SCG to SN, or the terminal initiates a request to activate and/or deactivate SN, PSCell or SCG to MN;

(3) Fourth information indicating that the PCell or MCG connection is allowed to be quickly restored when the SCG is in a deactivated state.

Fast recovery refers to the following manner of operation: the network side configures the UE to execute a fast PCell or MCG Failure (Failure), and when the UE detects the PCell or MCG Failure, the UE may report that the PCell or MCG Failure is reported through the SN, the SN notifies the MN again, and the subsequent MN sends an RRC reconfiguration, RRC release, etc. message to the UE through the SN. This may reduce the time of interruption between the UE and the MCG. If the network side does not configure the UE to execute the fast PCell or MCG Failure, the UE performs a reestablishment process with the network side terminal when detecting the PCell or MCG Failure.

In the embodiment of the present application, when the first configuration information includes fourth information, the first configuration information further includes: and a detection parameter for detecting RLF of the PCell or MCG in the SCG deactivated state.

In the embodiment of the present application, the network side device is SN or MN, and the method further includes:

And judging whether the terminal is allowed to initiate a request for activating and/or deactivating SN or PSCell or SCG according to the service of the terminal and/or the capability information of the terminal (such as information that UE service is mainly uplink service or downlink service, whether the UE needs electricity saving and the like).

In the embodiment of the present application, the network side device is an MN, and the method further includes:

receiving request information from the SN;

Wherein the request information includes one or more of the following:

The network side configures a mechanism for the UE whether the UE is allowed to trigger the activation and/or deactivation of the SN, the PSell or the SCG or not according to the service characteristics of the UE and the capability information of the UE, and particularly initiates a request for activation and/or deactivation to the MN or the PCell or the SN or the PScell if the UE is allowed to trigger the activation and/or deactivation of the SN/PSell/SCG. The method not only can ensure the controllable behavior of the UE in the connected state, but also can endow the UE with certain flexibility, so that the UE can flexibly activate or deactivate the SN/PSell/SCG. If the bearer (bearer) of the SCG is the MN terminated bearer (TERMINATED BEARER) or is mostly MN TERMINATED bearer or the bearer sensitive to time and/or rate requirements is MN TERMINATED bearer, activation and deactivation of SN, PSell or SCG should be decided by MN; on the other hand, if the beer of the SCG is SN TERMINATED beer, or mostly SN TERMINATED beer, or the beer sensitive to time and/or rate requirements is SN TERMINATED beer, activation and deactivation of SN, PSell, or SCG should be decided by SN. If activation and/or deactivation of the SN, the PSell or the SCG is triggered by the UE, the UE shall initiate a request for activation or deactivation towards the MN or SN.

When the SCG is in a deactivated state, since the radio link between the UE and the SCG is not a common radio resource control (Radio Resource Control, RRC) connection state, failure information of the PCell or the MCG cannot be fed back in time, so that the UE waits for a subsequent instruction of the PCell or the MCG for too long, and a new mechanism needs to be introduced to realize fast recovery of the PCell or the MCG connection.

Referring to fig. 4, an embodiment of the present application provides a configuration method, which is executed by a terminal, including:

step 401: when SN or SCG or PSCell is in a deactivated state, if RLF occurs in the PCell or MCG, an activation request is sent to SN or SCG or PSCell.

In an embodiment of the present application, the method further includes: starting a timer; and if the timer is overtime and the confirmation message of the activation request is not received, initiating connection reestablishment.

In an embodiment of the present application, the activation request includes: activation reasons such as PCell or MCG failure.

In an embodiment of the present application, the method further includes:

In the dual connectivity scenario, if the terminal detects that a primary cell (PRIMARY CELL) or primary cell group (MASTER CELL group, MCG) has generated RLF and the terminal is configured with a mechanism to quickly resume PCell or MCG connectivity, the terminal may suspend transmission of all radio bearers of the MCG and forward MCG error information, such as measurement results of the MCG or SCG cell measured by the terminal, to the primary node MN through SN or SCG. Within a certain preset time period, the terminal may receive messages such as reconfiguration of radio resource control (Radio Resource Control, RRC) forwarded by the MN through the SCG, RRC release and the like, and perform subsequent operations; if the preset duration is exceeded, the terminal does not receive any message sent by the MN yet, and the terminal initiates a reestablishing process. By quickly recovering the PCell or MCG connection mechanism, the terminal can be helped to recover the connection with the PCell or MCG as soon as possible, thereby avoiding the terminal from initiating the reestablishment to enter an idle state and affecting the service experience of the terminal.

Referring to fig. 5, an embodiment of the present application provides a configuration method, which is executed by a network side device, including:

Step 501: and receiving an activation request sent by a terminal, wherein the activation request is sent by the terminal when the PCell or the MCG generates RLF.

Step 1: optionally, the SN sends request information to the MN according to the service condition of the UE in the SCG, for example, the current service of the UE in the SCG is mainly uplink service, downlink service is less frequent, and the request allows the UE to trigger activation and/or deactivation of the SN or PSCell or SCG; in particular, the method comprises the steps of,

1) The SN may request that the UE be configured with only an activation SN or PSCell or SCG, or with only a deactivation SN, PSCell or SCG, or both;

2) Further, according to the situation of the SCG bearer, the SN may further carry: if the UE initiates a request for activation of SN or PSCell or SCG or initiates a request for deactivation of SN or PSCell or SCG, it should initiate to MN or SN, e.g. the UE may initiate a request for deactivation of SN, PSCell or SCG to MN or the UE may initiate a request for activation of SN or PSCell or SCG to SN;

Step 2: the MN judges whether to accept or modify the request of the SN (if the request information of the SN is received), or the MN judges that the UE is allowed to trigger the activation and/or deactivation of the SN or the PScell or the SCG and informs the SN;

step 3: the network side (MN or SN) configures to the UE whether allowed (whether allowed is not allowed, such as "1" for allowed, "0" for not allowed) or not (configured only if allowed, not allowed) the UE triggers activation and/or deactivation of SN or PSCell or SCG, in particular:

Embodiment III: the MN decides whether to allow the UE to trigger activation and/or deactivation of SN or PSCell or SCG, further, the SN may be notified:

referring to fig. 8, the specific steps are as follows:

Step1: the MN judges whether the UE is allowed to trigger the activation and/or deactivation of the SN, the PSCell or the SCG according to the service condition of the UE in the SCG, for example, the current service of the UE in the SCG is mainly uplink service, and the downlink service is not frequent;

step 2: the MN triggers activation and/or deactivation of the SN or PSCell or SCG by explicitly or implicitly configuring the UE whether allowed or not (whether allowed or not, e.g. "1" for allowed "and" 0 "for disallowed) or configuring the UE allowed (configured only when allowed, not configured for disallowed); specifically, the SN sends configuration information to the UE, where the content of the configuration information includes:

embodiment four: if SN decides activation of SCG:

Referring to fig. 9, the specific steps are as follows:

Step 1: optionally, the network side (MN or SN), or the PCell or PSCell, configures the UE with a connection that allows the scell or MCG to resume when the SCG is in a deactivated state;

a) If the network side is configured with the connection of the PCell or the MCG which is not allowed to be in the deactivated state, the UE directly initiates a reestablishment flow when the PCell or the MCG fails (failure);

b) If the network side is configured to allow the connection of the PCell or MCG to be restored when the SCG is in a deactivated state, a subsequent procedure is performed.

Step 2: since the deactivated UE needs more time to restore the connection of the PCell or MCG (because the SCG is activated first), the network side may also configure a set of (Radio Link Failure, RLF) detection parameters in the SCG deactivated state, such as a shorter timer T310, a smaller counter N311, to help the UE sense the risk of potential RLF faster;

step 3: when the SCG is in a deactivated state, if the PCell or the MCG generates RLF, in order to realize quick recovery of the connection of the PCell or the MCG, the UE actively initiates an activation request to the SN, the SCG or the PScell; further, the method comprises the steps of,

A) The activation request may carry an activation reason, such as PCell or MCG failure;

b) The UE can start a Timer (Timer) T1, i.e. if the Timer T1 times out and does not receive the acknowledgement of the activation request, the UE directly initiates the reestablishment, so that the UE can be prevented from being in the transmission interruption for too long;

Step 4: the SN or SCG or PSCell sends activation confirmation information to the UE;

Step 5: the UE sends related information of the PCell or the MCG failure, such as measured information of the MCG, the SCG or other cells, to the SN or the SCG or the PScell;

Step 6: the SN or SCG or PSCell sends relevant information of the PCell or MCG failure to the MN or MCG or PCell;

a) The MN, the MCG or the PCell sends information such as RRC reconfiguration, RRC release and the like to the UE through the SN, the SCG or the PSCell, and the UE completes the next operation according to the information.

The relevant information of PCell or MCG failure in step 5 may be transmitted together in step 3.

Fifth embodiment: if the MN decides activation of SCG:
