Description

SCG failure processing method, device, terminal and network side equipment

Technical Field

The present invention relates to the field of wireless technologies, and in particular, to a method, an apparatus, a terminal, and a network side device for processing an SCG failure in an auxiliary cell group.

Background

In the current wireless communication standard, when a Secondary Cell Group (SCG) failure occurs, for example, due to a SCG radio link failure, a T304 timer timeout, a consistency check failure, or an SRB3 integrity protection check failure, a User Equipment (UE) triggers an SCG failure reporting process, and sends SCG failure information to a Master base station (Master Node, MN).

In the current SCG failure information reporting process, the UE has only one secondary cell group SCG, so that after the SCG failure occurs in the secondary cell group, the UE suspends the bearer and data transmission of the SCG side in the secondary cell group, resets the MAC entity of the SCG, and waits for the response of the network side (MN), and the network side may release the failed SCG or reconfigure the SCG.

Therefore, in the current SCG failure processing, after the UE sends SCG failure information to the main base station, the UE waits for the instruction of the main base station, and before receiving the instruction of the main base station, the UE does not attempt to access the new target PSCell, which will cause SCG side data interruption, and cause SCG data interruption delay to be long.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

In order to solve the problem of long SCG data interruption time delay caused by SCG failure in the prior art, embodiments of the present invention provide a method for processing SCG failure, where after a conditional Primary SCG Cell (PSCell) is configured for a terminal, the terminal stores configuration information of a plurality of pscells, and the preconfigured PSCell configuration information can be used to implement faster recovery of SCG, thereby avoiding the problem of long SCG side data transmission interruption time delay caused by SCG failure.

It should be noted that the current communication standard introduces the concept of conditional PSCell addition and/or change, wherein the conditional PSCell addition and/or change provides one or more PSCell cells or SCG cell groups to which the terminal has access to a preconfigured target. The network side provides designated execution conditions for each pre-configured PSCell cell or SCG cell group at the same time, and the terminal evaluates the pre-configured PSCell cells according to the execution conditions configured by the network side after receiving the command containing the conditional PSCell configuration information. When the pre-configured PSCell cell meets the configured execution condition, the terminal may execute access in the cell, and complete the PSCell addition and/or change process. Taking the condition PSCell addition as an example, a specific example process is shown in fig. 1, and includes the following steps:

s101, a network MN configures measurement configuration information for UE;

s102, data transmission is carried out between the UE and the MN;

s103, the UE triggers a measurement report to the MN;

s104, the MN prepares a pre-configured target PSCell for the UE according to the measurement report, and sends a Secondary Node (SN) addition request message to a target SN base station (such as including SN1 and SN2), wherein the request message carries indication information of conditional SN addition;

s105, when the target SN base station determines that the terminal can be allowed to add, generating a confirmation message of the conditional SN addition request, and sending the confirmation message to the MN;

s106, the MN may configure a plurality of preconfigured target PSCell cells for the UE according to the measurement report of the UE, for example, add SN1 and SN2, respectively in this example, and send a Radio Resource Control (RRC) message including configuration information and execution conditions of the preconfigured target PSCell cells to the UE;

s107, the UE sends an RRC completion message to the MN as a response;

s108, the UE executes measurement, evaluates the pre-configured alternative PSCells according to configured execution conditions, and if a certain pre-configured PSCell measurement result meets the execution conditions, the UE executes SCG configuration information which is configured for the UE and contains the PSCells by a network side, executes a synchronization process and triggers a random access process to the PSCells; this example takes SN1 as an example;

s109, after the UE accesses the SN1, the UE can perform data interaction with the SN1 to complete the SN adding process.

According to the above process, by using the conditional PSCell configured by the MN for the UE, when the target PSCell meets the configured execution condition, the UE may execute access in the cell, and complete the PSCell addition process. Of course, the PSCell change procedure can also be completed using the conditional PSCell configured for the UE by the MN or the SN, similarly.

In the access method of the embodiment of the present invention, at least one condition PSCell configuration information configured for the UE side by the network side (e.g., MN and/or SN) is used, and after the SCG fails, the configuration of the SCG of one candidate PSCell in the at least one condition PSCell configured for the UE is executed, so as to avoid the problem of long data transmission interruption delay of the SCG side after the SCG fails.

The method for processing SCG failure of the auxiliary cell group in the embodiment of the invention is applied to a terminal, and as shown in figure 2, the method comprises the following steps:

s110, after reporting SCG failure information of the auxiliary cell group, selecting a pre-configured candidate PSCell as a target cell; wherein the candidate PSCell is a PSCell configured in the addition and/or change of the conditional PSCell;

s120, performing a configuration including the pre-configured SCG of the target cell.

By adopting the SCG failure processing method provided by the embodiment of the invention, under the condition that the PSCell of the main SCG cell is added and/or changed, a plurality of SCG configuration information are configured for the UE side, and the SCG configuration information can be utilized after SCG failure so as to reduce the data transmission interruption time delay of the SCG side. In an embodiment of the present invention, in step S110, the selecting a candidate PSCell in the adding and/or changing of a preconfigured conditional PSCell as a target cell includes at least one of: selecting the candidate PSCell as the target cell according to an execution instruction indicated by a network side; and selecting the candidate PSCell as the target cell after the timing duration of a preset timer is reached.

By adopting the processing method, in one embodiment, after the UE reports the SCG failure information of the secondary cell group, the network side can send an execution instruction to the UE to inform the UE to execute the configuration of one candidate PSCell added and/or changed by the existing conditional PSCell; in another embodiment, after the UE detects SCG failure or reports SCG failure information and the preset timer expires, the UE is allowed to execute configuration of one candidate PSCell in the existing addition and/or change of the conditional PSCell. The following describes two embodiments of the present invention for carrying out the above-described embodiments.
