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 and secondary cell (PSCell) or a Secondary Cell Group (SCG), or the terminal is not allowed to initiate a request for activating and/or deactivating a SN or a PSCell or a 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 configuration device, configuration equipment and a readable storage medium.

Background

In a scenario of dual connectivity, activation and deactivation of a Secondary Cell Group (SCG) is a mechanism that can accelerate a workflow for entering dual connectivity or dual connectivity. Because the power consumption of the terminal is large in the dual connectivity state, after the Secondary Node (SN)/SCG is added, if the service rate of the terminal decreases, the SN or the Primary Secondary Cell (PSCell) or the SCG may be in a deactivated or suspended or dormant state, and the network side may keep the context configuration information of the terminal instead of releasing the SN or the PSCell or the SCG. Therefore, the deactivation of the auxiliary station or the auxiliary cell group can save the power consumption of the terminal and can quickly recover the service of double connection 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, whether triggered by the network side MN or SN or by the UE.

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

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

step 201: 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 an SN or a PSCell or an SCG, or the terminal is not allowed to initiate a request for activating and/or deactivating an SN or a PSCell or an SCG.

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

(1) second information, the second information indicates the terminal to initiate a request for activating and/or deactivating an SN or a PSCell or SCG to an SN, or the terminal initiates a request for activating and/or deactivating an SN or a PSCell or SCG to a Master Node (MN);

(2) third information indicating that the terminal initiates a first resource for activating a SN or a PSCell or a SCG request, wherein the first resource comprises: a resource of a UL grant or a dedicated random access resource.

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

in this embodiment, when the fourth information is included in the first configuration information, the first configuration information further includes: detecting a parameter for detecting a Radio Link Failure (RLF) of the PCell or the MCG in the SCG deactivation 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 the PSell or the SCG.

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

step 301: sending 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 a SN or a PSCell or a SCG or that the terminal is not allowed to initiate a request to activate and/or deactivate a SN or a PSCell or a SCG.

(1) second information indicating that the terminal initiates a request to activate and/or deactivate a SN or a PSCell or a SCG to a SN, or that the terminal initiates a request to activate and/or deactivate a SN, a PSCell or a SCG to a 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 way of working: the network side configures that the UE can execute fast PCell or MCG Failure (Failure), then the UE reports the PCell or MCG Failure through the SN when detecting the PCell or MCG Failure, the SN notifies the MN again, and the subsequent MN sends messages such as RRC reconfiguration, RRC release and the like 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 rapid PCell or MCG Failure, the UE performs a reestablishment process with the network side terminal when detecting the PCell or MCG Failure.

In this embodiment of the present application, when the first configuration information includes fourth information, the first configuration information further includes: detecting parameters for detecting RLF of the PCell or the MCG in the SCG deactivation state.

In this embodiment of the present application, the network side device is an SN or an 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 or not according to the service of the terminal and/or the capability information of the terminal (such as information that the service of UE is mainly over industry service or downlink service, whether the UE needs to save power or not and the like).

In this 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:

fifth information requesting to allow the terminal to initiate a request to activate and/or deactivate an SN or a PSCell or an SCG;

and sixth information, which is used for requesting the terminal to initiate a request for activating and/or deactivating the SN or the PSCell or the SCG to the SN, or for configuring the terminal to initiate a request for activating and/or deactivating the SN or the PSCell or the SCG to the MN.

The network side configures the UE with a mechanism for allowing the UE to trigger activation and/or deactivation of SN, PSell or SCG or not according to the service characteristics of the UE and the capability information of the UE, and specifically initiating a request for activation and/or deactivation to MN or PCell or SN or PSCell if the UE is allowed to trigger activation and/or deactivation of SN, PSell or SCG. The method can ensure that the behavior of the UE in the connected state is controllable, and 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 a MN terminated bearer or mostly a MN terminated bearer or a bearer sensitive to latency and/or rate requirements is a MN terminated bearer, the activation and deactivation of the SN, the PSell or the SCG should be decided by the MN; on the other hand, if the bearer of the SCG is an SN terminated bearer, or mostly an SN terminated bearer or a bearer sensitive to latency and/or rate requirements is an SN terminated bearer, the activation and deactivation of the SN, the PSell or the SCG should be decided by the SN. If activation and/or deactivation of the SN, PSell, or SCG is triggered by the UE, the UE should initiate a request for activation or deactivation to the MN or SN.

When the SCG is in a deactivated state, because a Radio link between the UE and the SCG is not in a normal Radio Resource Control (RRC) connection state, failure information of the PCell or the MCG cannot be fed back in time, which results in an excessively long time for the UE to wait for a subsequent indication of the PCell or the MCG, and a new mechanism needs to be introduced to achieve fast recovery of PCell or MCG connection.

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

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

In an embodiment of the present application, the method further includes: starting a timer; and if the timer is out of time 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: the reason for activation, such as PCell or MCG failure (failure).

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

In a scenario of dual connectivity, if the terminal detects that a Primary Cell (Primary Cell) or a Master Cell Group (MCG) generates an RLF and the terminal is configured with a mechanism for quickly resuming a PCell or MCG connection, the terminal may suspend transmission of all radio bearers of the MCG and forward MCG error information, such as a measurement result of the MCG or the SCG Cell measured by the terminal, to a Master node MN through the SN or the SCG. Within a certain preset time, the terminal may receive messages such as Radio Resource Control (RRC) reconfiguration, RRC release and the like forwarded by the MN through the SCG, and perform subsequent operations; if the preset time length is exceeded and the terminal does not receive any message sent by the MN, the terminal initiates a reconstruction process. Through a quick recovery PCell or MCG connection mechanism, the terminal can be helped to recover the connection with the PCell or MCG as soon as possible, so that the situation that the terminal initiates reestablishment to enter an idle (idle) state and the service experience of the terminal is influenced is avoided.

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

step 501: receiving an activation request sent by a terminal, wherein the activation request is sent by the terminal when RLF occurs in a PCell or MCG.

In an embodiment of the present application, the activation request includes: the reason for activation.

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

In the embodiment of the application, the terminal can recover the connection with the PCell or the MCG as soon as possible through the activation request sent by the network side equipment, so that the user experience is improved.

The first embodiment is as follows: the SN decision allows the UE to trigger activation and/or deactivation of the SN or PSCell or SCG and inform the UE, and further, the MN.

Referring to fig. 6, the specific steps are as follows:

step 1: the SN judges whether the UE is allowed to trigger activation and/or deactivation of the SN or the PSCell or the SCG according to the service condition of the UE in the SCG, for example, the uplink service is the main service and the downlink service is not frequent in the service of the current UE in the SCG;

step 2: the SN triggers activation and/or deactivation of the SN or PSCell or SCG by explicitly or implicitly configuring the UE whether to allow (both allow and disallow, such as "1" for allow, "0" for disallow) or configuring the UE with allow (only when allowed, not for disallow); specifically, the SN sends configuration information to the UE, and the configuration information includes:

a) the SN only configures activation SN or PSCell or SCG or only configures deactivation SN or PSCell or SCG or both configurations for the UE;

b) the SN configures a request for initiating the activation or deactivation of the SN or the PSCell or the SCG to the MN for the UE, or the SN configures a request for initiating the activation or deactivation of the SN or the PSCell or the SCG to the SN for the UE;

c) optionally, the SN may also configure, when initiating a request for activating the SN, the PSCell, or the SCG, a resource of an uplink grant (UL grant) or a dedicated random access resource (the dedicated random access resource may be a resource of two-step random access, or may also be a resource of four-step random access) for the UE to help the UE to quickly complete a random access process and establish a connection with the SN, the PSCell, or the SCG;

and step 3: optionally, the SN sends configuration information to the MN, where the configuration information may include a) and/or b) in step 2);

and 4, step 4: the UE executes the activation or deactivation process of the SN or the PSCell or the SCG according to the configuration of the SN.

Example two: SN initiation, MN decision whether to allow the UE to trigger activation and/or deactivation of the SN or PSCell or SCG:

referring to fig. 7, the specific steps are as follows:

step 1: optionally, the SN sends request information to the MN to request to allow the UE to trigger activation and/or deactivation of the SN, PSCell, or SCG according to a service condition of the UE in the SCG, for example, that the current service of the UE in the SCG is mainly uplink service and downlink service is infrequent; in particular, it is possible to use, for example,

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

2) further, according to the SCG bearer, the SN may also carry: if the UE initiates a request for activation of or deactivation of the SN or PSCell or SCG, it should initiate towards the MN or the SN, e.g. the UE may initiate a request for deactivation of the SN, PSCell or SCG towards the MN, or the UE may initiate a request for activation of the SN or PSCell or SCG towards the 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 to allow the UE to trigger the activation and/or deactivation of the SN or the PSCell or the SCG and informs the SN;

and step 3: the network side (MN or SN) configures the UE with permission (for example, "1" indicates permission, "0" indicates non-permission) or with permission (only when allowed, or not) to trigger the activation and/or deactivation of the SN or PSCell or SCG, in particular:

1) the network side (MN or SN) can configure the UE with only activation SN or PSCell or SCG, or only deactivation SN or PSCell or SCG, or both;

2) the network side (MN or SN) may further be configured to, if the UE initiates a request to activate or deactivate the SN or PSCell or SCG, initiate the SN or the SN, for example, the UE initiates a request to deactivate the SN or PSCell or SCG or the UE initiates a request to activate the SN or PSCell or SCG to the SN;

3) optionally, the MN or the SN may also configure, when initiating a request to activate the SN or the PSCell or SCG, a resource of a UL grant or a dedicated random access resource, where the dedicated random access resource may be a resource of two-step random access or may also be a resource of four-step random access, so as to help the UE to quickly complete a random access process and establish a connection with the SN or the PSCell or SCG;

and 4, step 4: the UE performs activation or deactivation of the SN or PSCell or SCG according to the configuration of the network side (MN or SN).

Example three: the MN decides whether to allow the UE to trigger activation and/or deactivation of the SN or PSCell or SCG, and further may inform the SN:

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

step 1: the MN judges whether the UE is allowed to trigger 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 uplink service is mainly used for the service of the current UE in the SCG, 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 (either allowed or not, e.g., "1" for allowed, "0" for not allowed) or allowed (only allowed, but not allowed); specifically, the SN sends configuration information to the UE, and the content of the configuration information includes:

a) the MN configures the UE with only activated SN, PSCell or SCG, or only de-activated SN, PSCell or SCG, or both;

b) further, according to the SCG bearer, the configuration information may also carry: if the UE initiates a request for activation or deactivation of the SN, PSCell, or SCG, the UE initiates the SN or the SN, for example, the UE initiates a request for deactivation of the SN, PSCell, or SCG, or the UE initiates a request for activation of the SN, PSCell, or SCG;

c) optionally, the MN may also configure, when initiating a request for activating the SN, PSCell, or SCG, the UE with a resource of a UL grant or a dedicated random access resource, where the dedicated random access resource may be a resource of two-step random access or may also be a resource of four-step random access, so as to help the UE to quickly complete a random access procedure and establish a connection with the SN, PSCell, or SCG;

and step 3: optionally, the MN informs the SN of the configuration information, including a) and/or b) in step 2);

and 4, step 4: the UE performs activation or deactivation of the SN or PSCell or SCG according to the configuration of the MN.

The following describes a procedure for quickly recovering a PCell or MCG connection in the embodiment of the present application with reference to the fourth embodiment and the fifth embodiment:

example four: if the 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 SCG to recover the PCell or MCG when the SCG is in a deactivated state;

a) if the network side is configured with a connection that does not allow the SCG to recover the PCell or the MCG when the SCG is in the deactivated state, the UE directly initiates a reconstruction flow when the PCell or the MCG fails (failure);

b) and if the network side is configured with the connection which allows the SCG to recover the PCell or the MCG when the SCG is in the deactivated state, performing the subsequent flow.

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

and step 3: when the SCG is in a deactivation state, if RLF occurs to the PCell or the MCG, in order to realize rapid recovery of connection of the PCell or the MCG, the UE actively initiates an activation request to the SN, the SCG or the PSCell; further, in the present invention, it is preferable that,

a) the activation request may carry an activation reason, such as PCell or MCG failure;
