Technical field

The embodiments of the present application relate to the field of communication technologies, and in particular, to a configuration method, device, device, and storage medium of a network device.

Background technique

In order to further improve the mobile performance of the terminal, CHO (Conditional Handover) and CPC (Conditional PSCell Change) and CPC (Conditional PSCell Change) are introduced in 3GPP (3rd Generation Partnership Project) Release 16. ) Two technical features, where CHO is limited to single-connection or dual-connection primary CG (Cell Croup, cell group) use, and CPC is limited to dual-connection secondary CG use. In this way, in actual operation, it may exist that two network entities, MN (Master Node, primary node) and SN (Secondary Node, secondary node), simultaneously configure the two processes of CHO and CPC.

Among them, CHO is a newly introduced technology in Release 16, as shown in Figure 1, which roughly includes the following processes:

1. The source base station sends a measurement request to UE (User Equipment).

2. The UE returns the measurement result to the source base station.

3. The source base station decides to perform the CHO operation.

4. The source base station sends a CHO request message to the target base station and other potential target base stations.

5. The target base station and other potential target base stations that have received the request information perform the permission control operation.

6. The target base station and other potential target base stations that have received the requested information return CHO corresponding messages to the source base station.

7. The source base station sends an RRC reconfiguration message to the UE, where the RRC Reconfiguration includes the CHO candidate configuration and the CHO execution conditions.

8. The UE returns an RRC reconfiguration complete message to the source base station.

9. The UE continues to maintain the link with the source base station and begins to evaluate the CHO execution conditions.

10. If at least one candidate cell meets the execution conditions, the UE will disconnect from the source base station and initiate a random access procedure to the target cell.

11. The UE starts to send an RRC reconfiguration complete message to the target cell.

The CPC process distinguishes between inter-SN (between different SNs) and intra-SN (within the same SN). Currently, Release 16 only supports the intra-SN CPC process. For the intra-SN CPC process, the scenario where SRB3 is configured is shown in Figure 2. As shown, it roughly includes the following processes:

1. The SN sends an RRC reconfiguration message to the UE.

2. The UE returns an RRC reconfiguration complete message to the SN, where the RRC reconfiguration complete message contains the candidate cell configuration message of the CPC and the execution conditions of the CPC.

3. The UE starts to evaluate the candidate cells of the CPC, and if at least one candidate cell can meet the execution conditions of the CPC, it initiates a random access procedure to the target cell.

In the prior art, the CHO process and the CPC process are two independent processes. Therefore, when the UE is in dual connectivity, the two processes of MN configuring CHO and SN configuring CPC may occur at the same time, and such operations directly lead to The protocol stack processing on the terminal side is very complicated.

To sum up, in the prior art, when the UE is in a dual connection, the two processes of MN configuring CHO and SN configuring CPC may occur simultaneously, and the protocol stack cannot maintain a simple and efficient processing mechanism.

Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

The following explains some of the words that appear in the text:

1. The term "master node" in the embodiments of the present application, the UE can be connected to two or more nodes at the same time under dual connection or multi-connection. One of the nodes is called the master node, and the other nodes are called secondary nodes.

2. The term "secondary node" in the embodiments of the present application, the UE can maintain connection with two or more nodes at the same time in dual connection or multi-connection, and nodes other than the primary node are called secondary nodes.

Those of ordinary skill in the art will know that as new application scenarios change It appears that the technical solutions provided in the embodiments of the present application are equally applicable to similar technical problems. Wherein, in the description of the present application, unless otherwise specified, "multiple" means two or more.

In view of the fact that in the prior art, when the UE is in dual connectivity, the two processes of MN configuring CHO and SN configuring CPC may occur at the same time. This embodiment of the application provides a network device configuration solution to In the dual connection, the two processes of MN configuring CHO and SN configuring CPC are restricted to occur simultaneously, so that the protocol stack can maintain a simple and efficient processing mechanism.

Hereinafter, the configuration method of the network device provided by the embodiment of the present application will be described in detail with specific embodiments in conjunction with the accompanying drawings.

Example one

As shown in Figure 3, in the NR-DC (dual connection of 4G radio access network and 5G NR) scenario, the master node MN notifies the slave node SN of the current CHO or CPC status, which may include the following steps:

Step 301: The UE maintains dual connections with the primary node MN and the secondary node SN.

In step 302, the MN decides to perform the CHO operation after the first preset duration. At the same time, in order to prevent the SN from performing the CPC operation at the same time, the MN sends a first request message, which carries an indication: the MN is about to perform the CHO operation, or the SN is not allowed to perform the CPC operation operate.

In specific implementation, the MN decides to perform the CHO operation after the first preset duration, that is, the MN is about to perform the CHO operation. The first preset duration can be set according to empirical values, such as 30s, 10s, 5s, etc. Not limited.

It should be noted that, in addition to sending the first request message by the MN, other related processes in the UE may also be used to notify the SN, such as the configuration process of CHO.

Step 303: After receiving the first request message, the SN returns a first response message, and accordingly, the SN does not perform CPC operations any more.

In specific implementation, when the SN receives the first request message, if the CPC operation is not performed, the first response message is returned, indicating that the CPC operation is not performed temporarily. If the CPC operation needs to be performed after the first response message is returned, it waits for the MN to send The second request message of the SN can be executed after receiving the second request message; when the SN receives the first request message and is performing the CPC operation, it immediately stops performing the CPC operation and returns the first response message, waiting to be received by the MN The execution can only continue after the second request message is sent.

It should be noted that for this type of configuration message, SN does not allow rejection, and the CHO operation of MN is executed first.

Step 304, the MN continues to perform the CHO operation.

In step 305, the MN completes the CHO operation, including the success of the CHO operation or the failure of the CHO operation.

In step 306, the MN no longer intends to perform the CHO operation, and the MN sends a second request message to the SN. The message carries an indication: the master node does not intend to perform or has completed the CHO operation, or allows the SN to perform the CPC operation.

It should be noted that it is also allowed to use other related procedures in the UE to notify the SN.

Step 307: After receiving the second request message, the SN returns a second response message. Accordingly, the SN can perform CPC operations subsequently.

It should be noted that for this type of configuration message, SN does not allow rejection.

Example two

As shown in Figure 4, in EN-DC (5G NR and 4G radio access network dual connectivity), MR-DC (multi-RAT dual connectivity) scenarios, the master node MeNB notifies the slave node SgNB of the current CHO or CPC status, It can include the following steps:

In step 401, the UE maintains dual connectivity with the primary node MeNB and the secondary node SgNB.

In step 402, the MeNB decides to perform the CHO operation after the first preset duration. At the same time, in order to prevent the SgNB from performing the CPC operation at the same time, the MeNB sends a first request message, which carries an indication: the MeNB is about to perform the CHO operation, or the SgNB is not allowed to perform the CPC operation. operate.

In specific implementation, the MeNB decides to perform the CHO operation after the first preset duration, that is, the MeNB is about to perform the CHO operation, where the first preset duration can be set according to empirical values, such as 30s, 10s, 5s, etc. Not limited.

It should be noted that, in addition to sending the first request message by the MeNB, other related procedures in the UE can also be used to notify the SgNB, such as the configuration procedure of CHO.

Step 403: After receiving the first request message, the SgNB returns a first response message, and accordingly, the SgNB does not perform CPC operations.

In specific implementation, when the SgNB receives the first request message, if the CPC operation is not performed, the first response message is returned, indicating that the CPC operation is not performed temporarily. If the CPC operation needs to be performed after the first response message is returned, it waits for the MeNB to send The second request message can be executed after receiving the second request message; when the SgNB receives the first request message and is performing the CPC operation, it immediately stops performing the CPC operation, and returns the first response message, waiting to be received by the MeNB The execution can only continue after the second request message is sent.

It should be noted that for this type of configuration message, SgNB does not allow rejection, and the MeNB's CHO operation is executed first.

In step 404, the MeNB continues to perform the CHO operation.

In step 405, the MeNB completes the CHO operation, including the success of the CHO operation or the failure of the CHO operation.

In step 406, the MeNB no longer intends to perform the CHO operation, and the MeNB sends a second request message to the SgNB. The message carries an indication: the primary node does not intend to perform or has completed the CHO operation, or the secondary node is allowed to perform the CPC operation.

It should be noted that other related procedures in the UE are also allowed to notify the SgNB.

Step 407: After receiving the second request message, the SgNB returns a second response message. Accordingly, the SgNB can perform CPC operations subsequently.

It should be noted that SgNB does not allow rejection for this type of configuration message.

Example three

As shown in Figure 5, in the NR-DC scenario, the secondary node SN notifies the primary node MN of the current CHO or CPC status, which may include the following steps:

In step 501, the UE maintains dual connections with the primary node MN and the secondary node SN.

In step 502, the SN decides to perform intra-SN CPC or inter-SN CPC operation after the third preset duration. To prevent the MN from performing the CHO operation at the same time, the SN sends a third request message to the MN. The message carries an indication: SN is about to perform intra -SN CPC or inter-SN CPC operation, or MN is not allowed to perform CHO operation.

In specific implementation, the SN decides to perform the CPC operation after the third preset time period, that is, the SN is about to perform the CPC operation. The third preset time period can be set according to experience values, such as 30s, 10s, 5s, etc. Not limited.

It should be noted that, in addition to sending the third request message by the SN, other related processes in the UE may also be used to notify the MN, such as the CPC configuration process. At the same time, for this type of configuration message, the MN allows rejection.

In step 503, the MN receives the third request message and determines that the CHO operation is not performed within the second preset time period, and then returns a third response message, which carries an indication: allowing the secondary node to perform the CPC operation.

In specific implementation, when the MN determines that it receives the third request message and determines not to perform the CHO operation within the second preset time period, it returns a third response message to allow the SN to perform the CPC operation; when the MN receives the third request message When the message is requested, the CHO operation will be performed within the second preset time period, or the CHO operation is being performed, the MN rejects the message request and returns a fourth response message. The message carries an instruction: the secondary node is prohibited from performing the CPC operation. At this time, the CHO-related operations of the MN are executed first, and after the MN completes the CHO operation, the third response message is sent to the SN, and the SN starts to perform the CPC operation. Among them, the second preset duration can be set according to empirical values, such as 30s, 10s, 5s, etc., which is not limited in this application.

Of course, it should be noted that, in other embodiments of the present application, when the MN determines that it receives the third request message and determines not to perform the CHO operation within the second preset time period, it returns a third response message to allow the SN Perform the CPC operation; when the MN receives the third request message and will perform the CHO operation within the second preset time period, or is performing the CHO operation, the MN can also suspend the execution of the CHO operation and return the third response message, and After waiting to receive the fourth request message sent by SN, continue to perform the CHO operation.

In step 504, the SN starts to perform the CPC operation.

Step 505, the SN completes the CPC operation, including the success of the CPC operation or the failure of the CPC operation.

In step 506, the SN no longer intends to perform the CPC operation, and the SN sends a fourth request message to the MN. The message carries an indication: the SN does not intend to perform or has completed the CPC operation, or the master node allows the execution of the CHO operation.

It should be noted that it is also allowed to use other related procedures in the UE to notify the MN.

Step 507: After receiving the fourth request message, the MN returns a fifth response message. Accordingly, the MN can perform a CHO operation subsequently.

It should be noted that for this type of configuration message, the MN is not allowed to refuse.

Example four

As shown in Figure 6, in EN-DC and MR-DC scenarios, the secondary node SgNB notifies the master node MeNB of the current CHO or CPC status, which may include the following steps:

Step 601: The UE maintains dual connectivity with the primary node MeNB and the secondary node SgNB.

Step 602: SgNB decides to perform intra-SN CPC or inter-SN CPC operation after the third preset duration. In order to prevent MeNB from performing CHO operation at the same time, SgNB sends a third request message to MeNB. The message carries an indication: SgNB is about to perform intra -SN CPC or inter-SN CPC operation, or MeNB is not allowed to perform CHO operation.

In specific implementation, SgNB decides to perform the CPC operation after the third preset duration, that is, SgNB is about to perform the CPC operation. The third preset duration can be set according to empirical values, such as 30s, 10s, 5s, etc. Not limited.

It should be noted that, in addition to sending the third request message by the SgNB, other related processes in the UE may also be used to notify the MeNB, such as the CPC configuration process. At the same time, for this type of configuration message, the MeNB allows rejection.

In step 603, the MeNB receives the third request message and determines that the CHO operation is not performed within the second preset time period, and then returns a third response message. The message carries an indication that the secondary node is allowed to perform the CPC operation.

In specific implementation, when the MeNB receives the third request message and determines not to perform the CHO operation within the second preset time period, it returns a third response message to allow the SgNB to perform the CPC operation; when the MeNB receives the third request When the message is sent, the CHO operation will be performed within the second preset time period, or the CHO operation is being performed, the MeNB rejects the message request and returns a fourth response message, which carries an indication that the secondary node is prohibited from performing the CPC operation. At this time, the CHO-related operations of the MeNB are preferentially performed. After the MeNB completes the CHO operation, the third response message is sent to the SgNB, and the SgNB starts to perform the CPC operation. Among them, the second preset duration can be set according to empirical values, such as 30s, 10s, 5s, etc., which is not limited in this application.

Of course, it should be noted that, in other embodiments of the present application, when the MeNB determines that the third request message is received and determines not to perform the CHO operation within the second preset time period, it returns a third response message to allow SgNB Perform the CPC operation; when the MeNB receives the third request message and will perform the CHO operation within the second preset time period, or is performing the CHO operation, the MeNB can also suspend the execution of the CHO operation and return the third response message, and After waiting to receive the fourth request message sent by SgNB, continue to perform the CHO operation.

In step 604, the SgNB starts to perform the CPC operation.

In step 605, the SgNB completes the CPC operation, including the success of the CPC operation or the failure of the CPC operation.

In step 606, the SgNB no longer intends to perform the CPC operation, and the SgNB sends a fourth request message to the MeNB. The message carries an indication: the SgNB does not intend to perform or has completed the CPC operation, or the master node allows the CHO operation to be performed.
