Technical terms related to technical solutions provided in the embodiments of the present application will be explained below.

1) DC (Dual Connectivity, double connection)

Dual Connectivity, i.e. providing the UE with resources of two network nodes (access network elements), one of which is called MN (Master node) and the other is called SN (Secondary node). At each network node, carrier aggregation technology (CA) is used, i.e. a series of serving cells, also called cell groups (cell groups), controlled by the node are configured for the UE. The Master node MN controls a Master Cell Group (MCG) and the Secondary node SN controls a Secondary Cell Group (SCG). Each Cell group comprises a Special Cell (SpCell) and a series of Secondary cells (Scell). A special Cell is called a Primary Cell (PCell) in the MCG, and a Primary Secondary Cell (PSCell) in the SCG. The SpCell uses the primary carrier in one cell group, while the other secondary cells use the secondary carriers, and resource scheduling in one cell group is performed by the SpCell.

2) Conditional Primary and Secondary cell Addition (CPA)

CPA means: and the UE evaluates the execution condition and executes the addition of the primary and secondary cells after the execution condition is met. The CPA configuration comprises the configuration and execution conditions of the CPA candidate cell. The execution conditions may include one to two trigger conditions.

3) Conditional Primary and Secondary cell Change (CPC)

CPC means: and the UE evaluates the execution conditions and executes the change of the primary and secondary cells after the execution conditions are met. The UE starts evaluating the execution condition after receiving the CPC configuration. And the UE stops evaluating the execution conditions after the change of the primary cell and the secondary cell is triggered. The CPC configuration includes configuration and execution conditions of CPC candidate cells. The execution conditions may include one to two trigger conditions. Typically, the UE releases all stored CPC configurations upon successful completion of the primary-secondary cell change procedure.

Specifically, the CPC includes a variety of scenarios, such as:

-primary-secondary cell condition change within secondary node (Intra-SN CPC);

-master-slave Inter-node primary-secondary cell condition change (MN initiated Inter-SN CPC) initiated by the master node;

secondary node initiated primary and secondary Inter-node primary and secondary cell condition change (SN initiated Inter-SN CPC).

Currently, primary-secondary cell condition change within secondary nodes (Intra-SN CPC) has been supported. A discussion of how to support the conditional primary and secondary cell addition procedure is already in question.

It should be noted that, the conditional primary and secondary cell addition may also be referred to as conditional primary and secondary cell addition; the conditional primary and secondary cell change may also be referred to as a conditional primary and secondary cell change. The embodiment of the present application is not limited to this.

4) Primary and secondary cell configuration

Wherein, the configuration of the primary and secondary cells comprises: CPA and/or CPC. It should be noted that the primary and secondary cell configurations described above may be collectively referred to as CPAC, i.e., CPAC is a generic term for CPA and/or CPC. CPAC refers to the conditional addition and/or change process of the primary and secondary cell groups.

It should be noted that, in the Release-16 protocol, before the UE processes the received reconfiguration message, the UE should complete the ongoing primary-secondary cell condition change within the secondary node (Intra-SN CPC) process.

Currently, in the process of executing addition and/or change of primary and secondary cells, when a UE receives a reconfiguration message, the UE needs to process the reconfiguration message after completing the currently performed addition and/or change process of the primary and secondary cells. For example, if the UE performs other mobility procedures (e.g., primary cell handover) during the CPAC execution process, the UE performs a configuration procedure of the primary cell handover after the CPAC execution is finished. On one hand, extra time delay is generated in the reconfiguration process of the UE, and the processing efficiency of the UE on the signaling is reduced. On the other hand, if some configuration parameters change after the UE completes performing the reconfiguration, such as a change of the primary cell, a security parameter update, etc., the addition and/or change process of the primary and secondary cells is useless, thereby resulting in a waste of system resources. For example, if the primary cell changes after the UE performs the reconfiguration procedure, the executed addition and/or change procedure of the primary and secondary cells may be useless.

Therefore, how to process the ongoing CPAC procedure and the newly received reconfiguration command by the UE in the CPAC execution process achieves to complete the reconfiguration procedure as soon as possible, and reduces the signaling processing delay, which is a problem to be solved urgently.

In order to solve the above problem, embodiments of the present application provide a primary and secondary cell configuration method, apparatus, UE, and readable storage medium, where in a case where a first reconfiguration message is received, the UE performs conditional primary and secondary cell configuration, and the UE may stop a conditional evaluation procedure of the conditional primary and secondary cell configuration in a case where a first predetermined condition is satisfied, or terminate an execution procedure of the primary and secondary cell configuration in a case where the UE is executing the primary and secondary cell configuration procedure. For example, upon receiving the reconfiguration message, the UE aborts the ongoing execution procedure of the conditional primary and secondary cell configuration. Therefore, the UE can process the newly received reconfiguration message quickly, delay caused by continuously executing the configuration of the conditional primary and secondary cells is avoided, abnormity generated in the subsequent process of the configuration of the conditional primary and secondary cells is also avoided, and the signaling processing efficiency is improved.

The primary and secondary cell configuration method provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings by using some embodiments and application scenarios thereof.

The embodiment of the present application provides a method for configuring a primary cell and a secondary cell, which may be applied to a UE, and illustrates a flowchart of the method for configuring the primary cell and the secondary cell provided in the embodiment of the present application. As shown in fig. 2, the method for configuring a primary cell and a secondary cell provided in the embodiment of the present application may include the following steps 101 and 102:

step 101: and under the condition of receiving the first reconfiguration message, the UE performs a primary and secondary cell configuration process.

Wherein, the first reconfiguration message is used for configuring a primary cell and a secondary cell; the primary and secondary cell configuration process includes: performing condition evaluation and/or execution of primary and secondary cell configuration; the configuration of the primary and secondary cells includes: CPA and/or CPC.

In the embodiment of the present application, when configuring a conditional primary and secondary cell, the UE first evaluates an execution condition, and executes addition or change of the primary and secondary cells after the execution condition is satisfied.

In an embodiment of the present application, the first configuration re-message includes: information and execution conditions of the candidate cell; the candidate cell may be a candidate secondary cell group, and the execution condition includes at least one trigger condition.

Illustratively, the UE evaluates whether the candidate cell satisfies the handover execution condition, and selects a target cell to add or handover (i.e. change) after the condition is satisfied, in case that the UE receives the reconfiguration message.

Step 102: the UE performs a first operation if a first predetermined condition is satisfied.

Wherein the first operation includes any one of:

stopping the condition evaluation process of the configuration of the primary and secondary cells;

and in the case that the UE is executing the primary and secondary cell configuration process, the execution process of the primary and secondary cell configuration is suspended.

In the embodiment of the present application, the process of configuring the conditional primary and secondary cells by the UE includes two stages, one stage is an execution condition evaluation stage, and the other stage is a configured execution stage (i.e., addition or change).

For example, before executing the first operation, the UE may first determine a stage corresponding to the conditional primary and secondary cell configuration process, and determine the processing operation performed in the current stage according to the stage corresponding to the conditional primary and secondary cell configuration process, without performing the two processing operations, so as to perform processing on the conditional primary and secondary cell configuration process in a targeted manner.

Illustratively, when the UE determines that the configuration process of the conditional primary and secondary cells is in the condition evaluation stage, the UE stops the condition evaluation of the conditional primary and secondary cells; and when the UE judges that the configuration process of the conditional primary and secondary cells is in the execution stage of the configuration, the UE stops the execution of the configuration. Therefore, the UE can perform processing operation in a targeted manner according to the actual configuration condition of the conditional primary and secondary cells, and the processing efficiency is improved.

In the primary and secondary cell configuration method provided in the embodiment of the present application, the UE performs conditional primary and secondary cell configuration when receiving the first reconfiguration message, and the UE may stop the conditional evaluation process of the conditional primary and secondary cell configuration when meeting the first predetermined condition, or suspend the execution process of the primary and secondary cell configuration when the UE is executing the primary and secondary cell configuration process. For example, in case of receiving the reconfiguration message, the UE aborts the ongoing execution procedure of the conditional primary and secondary cell configuration. Therefore, the UE can process the newly received reconfiguration message quickly, delay caused by continuously executing the configuration of the conditional primary and secondary cells is avoided, abnormity in the subsequent process of the configuration of the conditional primary and secondary cells is also avoided, and the signaling processing efficiency is improved.

Optionally, in an embodiment of the present application, the first predetermined condition includes at least one of:

the UE receives a second reconfiguration message;

the UE high layer releases the auxiliary cell group;

and the UE high layer terminates the secondary cell group adding process.

Wherein, the second reconfiguration message is a Radio Resource Control (RRC) reconfiguration message; the second reconfiguration message carries a target command and/or a target parameter; the second reconfiguration message is used for providing configuration parameters for the UE. It should be noted that, the UE receives the second reconfiguration message to characterize that the UE needs to perform the reconfiguration process.

For example, the UE may determine whether to perform the configuration procedure of the primary and secondary cells currently when receiving the second reconfiguration message, and execute the first operation if the UE is performing the configuration procedure of the primary and secondary cells currently.

For example, in the case of the UE primary and secondary cell configuration procedure, if it is detected that the first predetermined condition is met, the UE may stop the condition evaluation procedure for the primary and secondary cell configuration, or, in the case that the UE is executing the primary and secondary cell configuration procedure, terminate the execution procedure for the primary and secondary cell configuration.

Further optionally, in this embodiment of the application, when the first predetermined condition includes that the UE receives the second reconfiguration message, the UE may determine whether the second reconfiguration message includes the target command when receiving the second reconfiguration message, and if the second reconfiguration message includes the target command, execute the first operation.

For example, in the case that the UE receives the second reconfiguration message, the process of step 102 may include the following steps 102a:

step 102a: and under the condition that the UE receives the second reconfiguration message, if the second reconfiguration message comprises a target command, executing the first operation.

Wherein the target command comprises at least one of:

a switching command;

a security parameter update command;

a DAPS handover command;

a CHO command;

a secondary cell group release command;

a secondary cell group reconfiguration command;

wherein the secondary cell group reconfiguration command includes at least one of: secondary cell group change (SCG change) command, and secondary cell group addition (SCG addition) command.

Further, the target command in the second reconfiguration message is used to instruct the UE to perform reconfiguration.

Illustratively, the UE aborts or stops the CPAC procedure when any of the following conditions are met.

1) A handover procedure, i.e. the reconfiguration message carries a handover command (reconfiguration with sync);

2) Primary cell Change, i.e. the reconfiguration message indicates a primary cell Change (PCell Change);

3) Reconfiguring the security parameters, i.e. the reconfiguration message indicates to update the security parameters (reconfiguration with security key refresh);

4) And switching the conditions, wherein the process of switching the conditions comprises at least one of the following processes:

a) The UE starts to execute Conditional Handover (Conditional Handover-CHO) after the execution condition of the Conditional Handover is met;

b) The reconfiguration message carries a conditional switch command.

5) Dual Active Protocol Stack Handover (DAPS HO), i.e. the reconfiguration message carries the DAPS Handover command;

6) Releasing the auxiliary cell group; the process of the secondary cell group release comprises at least one of the following processes:

a) The reconfiguration message carries a secondary cell group release command (SCG release);

b) The UE releases the secondary cell group, such as the SCG release by Upper Layer.

7) The higher or upper layer terminates the secondary cell addition process.

It should be noted that the CPAC procedure includes at least one of the following: CPA (Conditional PSCell Addition), CPC (Conditional PSCell Change); the above-mentioned high layer or upper layer is a protocol layer above the RRC layer.

The technical solutions provided in the present application will be further described below with 3 examples.

Example 1: a procedure of suspending the primary and secondary cell configuration procedure will be exemplarily described below. Specifically, for a scenario in which the target command includes a handover command, a security parameter update command, or a DAPS handover command, the process includes the following steps 11 to 15.

Step 11: and the UE receives the first reconfiguration message and configures CPA or CPC.

Step 12: the UE performs conditional evaluation of CPAC. If the condition is satisfied, the UE triggers CPAC execution process.

Step 13: the UE receives the second reconfiguration message.

Wherein the second reconfiguration message carries at least one of:

a) A handover command, such as redirection with sync;

b) Security parameter update (security key refresh);

c) DAPS handover command.

Step 14: the UE stops evaluation of CPAC; or, if the UE is performing CPAC, the UE aborts the CPAC procedure.

Step 15: the UE continues to process the second reconfiguration message.

For example, when receiving the second reconfiguration message, and the second reconfiguration message includes the target command, the UE stops the condition evaluation of the primary and secondary cell configurations, or suspends the execution process of the primary and secondary cell configurations, so as to process the newly received reconfiguration message (i.e., the second reconfiguration message) timely and quickly, avoid the delay caused by continuing to execute the CPAC, and improve the processing efficiency of the signaling.

Example 2: a procedure of suspending the primary and secondary cell configuration procedure will be exemplarily described below. Specifically, for a scenario in which the target command includes a conditional switch command, the process includes the following steps 21 to 25.

Step 21: and the UE receives the first reconfiguration message and configures CPA or CPC.

Step 22: the UE performs conditional evaluation of CPAC. If the condition is met, the UE triggers a CPAC execution process;

step 23: the UE receives the second reconfiguration message. The second reconfiguration message carries a conditional switch command.

Step 24: the UE stops evaluation of CPAC. Or, if the UE is performing CPAC, the UE aborts the CPAC procedure.

Step 25: the UE continues to process the second reconfiguration message.

For example, when the UE receives the second reconfiguration message, and the second reconfiguration message includes the condition command, the UE stops the condition evaluation of the primary and secondary cell configurations, or stops the execution process of the primary and secondary cell configurations, so as to execute the conditional handover timely and quickly, avoid a handover delay caused by continuing to execute the CPAC, and improve the processing efficiency of the signaling.

Example 3: a procedure of suspending the primary and secondary cell configuration procedure will be exemplarily described below. Specifically, for a scenario in which the target command includes a secondary cell group release command, the process includes the following steps 31 to 35.

Step 31: and the UE receives the first reconfiguration message and configures CPA or CPC.

Step 32: the UE performs conditional evaluation of CPAC. If the condition is satisfied, the UE triggers CPAC execution process.

Step 33: the UE receives the second reconfiguration message. The second reconfiguration message carries a secondary cell group release command.

Step 34: the UE stops evaluation of CPAC. Or, if the UE is performing CPAC, the UE aborts the CPAC procedure.

Step 35: the UE continues to process the second reconfiguration message.

Illustratively, when the UE receives the second reconfiguration message, and the second reconfiguration message includes the secondary cell group release command, the UE stops the condition evaluation of the primary and secondary cell configuration, or suspends the execution process of the primary and secondary cell configuration, so that the secondary cell group release can be performed in time and quickly, the secondary cell group release delay caused by continuing to perform CPAC is avoided, and the primary and secondary cell configuration process is invalidated. And the processing efficiency of the signaling is improved.

It should be noted that, in the case that the second reconfiguration message includes the target command, the reconfiguration process corresponding to the second reconfiguration message may cause the primary and secondary cell configuration performed by the UE to be invalid or generate an exception, thereby causing a waste of air interface resources. Therefore, the UE may terminate the primary and secondary cell configuration procedure when the second reconfiguration message includes the target command, thereby improving the utilization rate of resources.

Further optionally, in this embodiment of the application, if the UE detects that a Conditional Handover (CHO) command is carried in the second reconfiguration message, the UE performs a conditional evaluation on the CHO and executes the first operation when the CHO condition is satisfied.

For example, the process of the UE performing the first operation in step 102 may include the following steps 102b1 and 102b2:

step 102b1: and under the condition that the second reconfiguration message carries a Conditional Handover (CHO) command, the UE performs the condition evaluation of the CHO.

Step 102b2: in case that the execution condition of the CHO is satisfied, the UE performs the first operation.

With reference to the step 102b1 and the step 102b2, after the step 102b2, the primary and secondary cell configuration method provided in this embodiment further includes the following step A1:

step A1: the UE triggers the execution procedure of the CHO described above.

For example, in case that the execution condition of the CHO is satisfied, in order to ensure that the reconfiguration process indicated by the CHO command carried by the second reconfiguration message can be executed as soon as possible, after the configuration process of the CPAC is aborted, the UE may trigger the execution process of the CHO described above, so as to continue executing the CHO.

Example 4: the following will exemplarily describe a procedure for suspending the primary and secondary cell configuration procedure when the conditional handover CHO command is carried in the second reconfiguration message. Specifically, the above process includes the following steps 41 to 45.

Step 41: and the UE receives the first reconfiguration message and configures CPA or CPC.

Step 42: the UE performs conditional evaluation of CPAC. If the condition is satisfied, the UE triggers CPAC execution process.

Step 43: the UE receives the second reconfiguration message. The second reconfiguration message carries a conditional handover Command (CHO).

Step 44: the UE performs a conditional evaluation of CHO.

Step 45: when the CHO condition is met, the UE aborts the CPAC procedure (i.e., the UE stops evaluation of CPAC; or, if the UE is performing CPAC, the UE aborts the CPAC procedure) and triggers the CHO to perform the procedure.

For example, the UE may stop the condition evaluation of the primary and secondary cell configuration or suspend the execution process of the primary and secondary cell configuration when the CHO execution condition is satisfied, so as to ensure that the execution process of the primary and secondary cell configuration is suspended only when the UE needs to execute the CHO, thereby improving the effectiveness of the processing on the primary and secondary cell configuration process.

It should be noted that, in the foregoing example, the receiving order of the first reconfiguration message and the second reconfiguration message may be arbitrary, or the first reconfiguration message and the second reconfiguration message may be received first, and this embodiment of the present application does not make any limitation on the order of the first reconfiguration message and the second reconfiguration message.

Further optionally, in this embodiment of the application, when the first predetermined condition includes that the UE receives the second reconfiguration message, after step 102, the method for configuring the primary and secondary cells provided in this embodiment of the application may further include step B1:

step B1: the UE continues to process the second reconfiguration message.

For example, in the process of configuring the conditional primary and secondary cells, if the UE receives the second reconfiguration message, the UE suspends the primary and secondary cell configuration process, and continues to process the second reconfiguration message after the primary and secondary cell configuration process is suspended, so as to normally provide the configuration parameters for the UE. For example, when the second reconfiguration message is used for the UE to switch the primary cell, the UE may continue to process the second reconfiguration message after the primary and secondary cell configuration procedures are suspended, so as to complete the switching of the primary cell as soon as possible.

Therefore, in the CPAC execution process, the UE may terminate the CPAC process and continue to process the newly received reconfiguration command, so as to complete the reconfiguration process corresponding to the reconfiguration command as soon as possible, reduce the signaling processing delay, and improve the signaling processing efficiency.

Further optionally, in this embodiment of the present application, when the first predetermined condition includes that the UE receives the second reconfiguration message, after step B1, the method for configuring a primary cell and a secondary cell provided in this embodiment of the present application may further include step B2:

and step B2: and after the reconfiguration process corresponding to the second reconfiguration message is completed, the UE releases the stored candidate cell configuration.

For example, the stored candidate cell configuration is configured as a candidate cell configuration stored when the UE performs the primary and secondary cell configurations.

For example, the UE may release the stored candidate cell configuration after sending an RRC reconfiguration complete message, where the RRC reconfiguration complete message is used to indicate that the reconfiguration process is completed.

For example, when the reconfiguration process is a handover process, the UE may release the stored CPAC candidate cell configuration after the handover is successful; when the reconfiguration process is a primary cell change process, the UE may release the CPAC candidate cell configuration after the primary cell change is successful; when the above reconfiguration procedure is conditional handover (i.e., CHO), the UE may release the stored CPAC candidate cell configuration after the conditional handover is successful.

Therefore, after the reconfiguration process is completed, the UE can release useless CPAC configuration, thereby saving network resources and further improving the processing efficiency of the newly received signaling.

Further optionally, in this embodiment of the application, in a case that the first predetermined condition includes that the UE higher layer releases the secondary cell group, the UE may perform the first operation described above in a case that the UE higher layer releases the secondary cell group.

Example 5: a procedure in which the UE suspends the primary and secondary cell configuration procedure in the case where the UE releases the secondary cell group in the higher layer will be exemplarily described below. Specifically, the above process includes the following steps 51 to 53.

Step 51: the UE receives the first reconfiguration message and configures CPC;

step 52: the UE performs a conditional evaluation of the CPC. If the condition is met, the UE triggers a CPC execution process;

step 53: and releasing the auxiliary cell group by the UE high layer. The UE stops the evaluation of CPC. Or, if the UE is performing CPC, the UE aborts the CPC procedure.

For example, the UE may abort the primary and secondary cell configuration procedure in case the higher layer releases the secondary cell group. Therefore, the UE stops CPC under the condition that the high-level releases the auxiliary cell group, so that the resource waste caused by the useless CPC process in execution is avoided, and the utilization efficiency of air interface resources is improved.

Further optionally, in this embodiment of the application, in a case where the first predetermined condition includes that the UE upper layer suspends the primary-secondary cell group addition procedure, the UE may perform the above-described first operation in a case where the UE upper layer suspends the secondary cell group addition procedure.

Exemplarily, the UE high-layer suspension of the adding process of the secondary cell group includes: and under the condition that the UE high layer suspends the adding process of the auxiliary cell group, the UE high layer suspends the executing process of the addition of the main and auxiliary cells under the condition.

Example 6: the procedure for UE high-level suspension of the primary and secondary cell configuration procedure will be exemplarily described below. Specifically, the above process includes the following steps 61 to 64.

Step 61: the UE receives the first reconfiguration message and configures CPA;

step 62: the UE performs conditional evaluation of the CPA. If the condition is met, the UE triggers a CPA execution process;

and step 63: the UE high layer stops the adding process of the auxiliary cell group;

step 64: the UE stops evaluation of the CPA. Or, if the UE is performing CPA, the UE aborts the CPA procedure.

For example, the UE may abort the primary-secondary cell addition in case the UE high layer aborts the secondary cell group addition procedure. Therefore, the CPA is actively suspended by suspending the auxiliary cell group adding process at the high level of the UE, so that the CPA configuration process is flexible and controllable, and the signaling processing efficiency is improved.

It should be noted that, the higher layer of the UE may actively terminate the CPA procedure, instead of terminating the CPA procedure after receiving the signaling of the network side, so that the CPA procedure may be terminated quickly, thereby improving the efficiency of processing the newly received reconfiguration message.

Optionally, in this embodiment of the present application, in a case that the UE is performing a primary and secondary cell configuration procedure, the suspending the primary and secondary cell configuration execution procedure includes at least one of:

releasing RLC bearing configured by SCG;

suspending an ongoing random access procedure on the target cell;

releasing the stored candidate cell configuration;

and releasing the uplink RRC message to be sent.

Illustratively, the UE aborts or stops the CPAC procedure, and the processing performed by the UE includes at least one of:

stop T304 timer of SCG (stop timer T304 for the SCG, if running);

resetting the SCG MAC, releasing the SCG MAC configuration (reset SCG MAC, release the SCG MAC configuration);

stopping CPA conditional reconfiguration evaluation (stop conditional reconfiguration for CPA, if configured);

stopping CPC condition reconfiguration evaluation (stop conditional reconfiguration evaluation for CPC, if configured);

releasing the SCG configured RLC bearer of SCG configuration;

when the CPAC is aborted, abort the ongoing Random Access procedure on the target cell (When CPAC is aborted, if any, is aborted);

if handover, release of stored CPAC candidate cell configurations (If HO) is performed. Or, release the stored CPAC candidate cell configuration after the handover is successful, for example, the UE releases the stored CPAC candidate cell configuration after detecting the handover instruction, or the UE releases the stored CPAC candidate cell configuration after the handover is completed;

and releasing the uplink RRC message to be sent, such as the SCGFailureinformation, the RRCReconfigurationcomplete message triggered by the CPAC and the like.

It should be noted that the UE may perform some or all of the above processing procedures to terminate or stop the CPAC procedure. The specific processing procedure that the UE needs to execute may be determined according to the actual configuration situation of the CPAC, which is not limited in this embodiment of the present application.

Further, the releasing of the uplink RRC message to be sent includes at least one of the following:

release secondary cell group Failure Information (SCG Failure Information);

releasing an RRC Reconfiguration Complete message (RRC Reconfiguration Complete Information); the RRC reconfiguration complete message is used to indicate that the conditional primary and secondary cell addition or the conditional primary and secondary cell change execution is complete.

Therefore, the UE can timely end the current CPAC configuration process under the condition that the secondary cell group fails or the configuration of the primary and secondary cells is completed, so that the subsequent signaling processing delay is reduced, and the signaling processing efficiency and the utilization rate of network resources are improved.

The embodiment of the present application provides another primary and secondary cell configuration method, which may be applied to a network side device, and illustrates a flowchart of the primary and secondary cell configuration method provided in the embodiment of the present application. As shown in fig. 3, the method for configuring a primary cell and a secondary cell provided in the embodiment of the present application may include the following steps 201 and 203:

step 201: the network side equipment sends a first reconfiguration message.

In this embodiment, the first reconfiguration message is used to configure a conditional primary cell and a conditional secondary cell.

Step 202: and the network side equipment sends a second reconfiguration message.

In this embodiment of the present application, the second reconfiguration message is used to provide configuration parameters for the UE.

In an embodiment of the application, the second reconfiguration message satisfies a second predetermined condition.

Illustratively, the second predetermined condition includes: the second reconfiguration message includes a target command, wherein the target command includes at least one of:

a switching command;

a security parameter update command;

a DAPS handover command;

a CHO command;

a secondary cell group release command;

a secondary cell group reconfiguration command;

wherein the secondary cell group reconfiguration command includes at least one of: a secondary cell group change command and a secondary cell group addition command.

Step 203: and after the network side equipment sends the second reconfiguration message, the network side equipment stops the configuration process of the primary and secondary cells.

Wherein, the configuration process of the primary and secondary cells comprises: performing condition evaluation and/or execution of primary and secondary cell configuration; the configuration of the primary and secondary cells includes: a conditional primary and secondary cell change or a conditional primary and secondary cell addition.

In this embodiment of the present application, the target message is a message sent by the UE to the network side device.

In an embodiment of the present application, the target message includes: RRC reconfiguration complete message or secondary cell group failure message; the RRC reconfiguration complete message is used to indicate that the conditional primary and secondary cell addition or the conditional primary and secondary cell change execution is complete.

For example, after the network side device sends the first reconfiguration message to the UE, the UE performs a primary and secondary cell configuration process, and then sends an RRC reconfiguration complete message or a secondary cell group failure message to the network side device to indicate that the network side device conditionally completes the execution of the primary and secondary cell configuration or fails the secondary cell group configuration.

Optionally, in this embodiment of the present application, the step 203 may include the following step 203a:

step 203a: and after the network side equipment sends the second reconfiguration message and does not receive the target message, the network side equipment stops the configuration process of the primary and secondary cells.

In this embodiment, when sending the second reconfiguration message, the network side device may determine whether the target message is received, and terminate the primary and secondary cell configuration process when the target message is not received.

It can be understood that, if the network-side device does not receive the target message when sending the second reconfiguration message, it indicates that the primary and secondary cell configuration process is in progress, and in this case, the network-side device may suspend the configuration process of the primary and secondary cells, so as to complete the reconfiguration process corresponding to the second reconfiguration message as soon as possible.

Optionally, in this embodiment, after the step 202, the method for configuring a primary cell and a secondary cell provided in this embodiment further includes the following step 204:

step 204: and under the condition that the network side equipment receives the target message, ignoring the target message.

Illustratively, after the network side device sends the second reconfiguration message, if the RRC reconfiguration complete message or the secondary cell group failure message is received, the network side device ignores the received RRC reconfiguration complete message or the received secondary cell group failure message, so that other processing operations can be performed as soon as possible, and the signaling processing efficiency is improved.

Optionally, in this embodiment of the present application, after the network side device suspends the configuration process of the primary and secondary cells in step 203, the method for configuring the primary and secondary cells provided in this embodiment of the present application further includes step 205:

step 205: and the network side equipment releases the candidate cells in the configuration process of the primary and secondary cells.

The method for releasing the candidate cell in the configuration process of the primary cell and the secondary cell by the network side equipment comprises at least one of the following steps:

after the network side equipment sends the second reconfiguration message, releasing the candidate cells in the configuration process of the primary and secondary cells;

and after receiving the second reconfiguration completion message, the network side equipment releases the candidate cells in the configuration process of the primary and secondary cells.

For example, the second reconfiguration complete message is a reconfiguration complete message sent by the UE to the network side device, and further, after the network side device sends the second reconfiguration message to the UE, the UE sends the second reconfiguration complete message to the network side device after completing the reconfiguration process corresponding to the second reconfiguration message. I.e. the second reconfiguration complete message is used to indicate that the reconfiguration procedure of the UE is complete.

As shown in fig. 4, an interaction method (i.e., another exemplary method for configuring a primary cell and a secondary cell) may be applied to the wireless communication system shown in fig. 1, where the method may include the following steps 301 to 304:

step 301: and the network side equipment sends a first reconfiguration message to the UE.

Step 302: and under the condition of receiving the first reconfiguration message, the UE performs a primary and secondary cell configuration process.

Step 303, the network side equipment sends a second reconfiguration message to the UE.

Step 304: and after the network side equipment sends the second reconfiguration message, the network side equipment stops the configuration process of the primary and secondary cells.
