Illustratively, the methods in the embodiments of the present application may be applied to a handover process. In this scenario, the first access network device may be the source base station, and the second access network device may be the target base station.

Specifically, the first access network device may also determine the configuration information of the AI service of the user equipment supported by the second access network device according to the configuration information of the AI service of the second access network device obtained when the target base station is selected , and only send the configuration information to the second access network device to reduce the size of the transmission signaling.

In some embodiments, the first access network device may send the first message to the second access network device in the following manner:

Manner 1: The first access network device directly sends the first message to the second access network device. In this case, the first access network device may send the first message to the second access network device through the Xn/X2 interface. For example, in a handover scenario, the first access network device may carry the first message in a handover request HANDOVER REQUEST message, and send it to the second access network device.

Manner 2: The first access network device sends the first message to the second access network device through the core network network element. Specifically, the first access network device may send the first message to the core network element through the NG interface, and the core network element may directly carry the first message in the handover request HANDOVER REQUEST message and forward it to the second access network device . Alternatively, the core network device may process the first message first, and forward the processed first message in a HANDOVER REQUEST message to the second access network device. For example, the core network element may be an AMF.

The above is only an example for the first access network device to send the first message, and the embodiment of the present application does not limit the manner in which the first access network device sends the first message to the second access network device. For example, the first access network device may send the first message to the second access network device through multiple network elements or devices.

Exemplarily, the at least one first AI service includes part or all of the AI services supported by the user equipment, or the at least one first AI service includes part or all of the AI services that the user equipment participates in.

Exemplarily, the first message may indicate at least one first AI service in the following manner:

Mode A, the first message may carry a service identifier of the first AI service, and the service identifier of the first AI service includes, for example, a service name of the first AI service.

For example, the service information of the AI service supported by the user equipment includes: the user equipment supports the AI positioning function, AI trajectory prediction, and AI load balancing (supported by the user equipment does not mean that the user equipment is currently participating in the wireless AI service). The first capability configuration information includes, for example, information such as: for the AI positioning function, types of positioning AI models supported by the user equipment, types of supported model segmentation modes, and data processing methods.

For example, the service information of the AI service that the user equipment is participating in includes, for example: the user equipment is participating in the AI positioning function and the AI trajectory prediction function. The second capability configuration information includes capability configuration information of the user equipment and capability configuration information of the base station side.

Specifically, the capability configuration information of the user equipment refers to the configuration information on the user equipment side for the wireless AI service that the user equipment is participating in, such as the model segmentation used by the user equipment side for the AI positioning function that the user equipment is participating in. Information such as mode, data processing configuration, etc.; the capability configuration information on the base station side refers to the configuration information on the base station side for the wireless AI service that the user equipment is participating in, such as the model used by the base station side for the AI trajectory prediction that the user equipment is participating in. information, the configuration of data processing, etc., the configuration information may not be visible to the user equipment.

Step 202: After receiving the first message, the second access network device sends a second message to the first access network device.

Correspondingly, the first access network device receives the second message from the second access network device.

In some embodiments, the second access network device may send the second message to the first access network device in the following manner:

Manner 1, the second access network device directly sends the second message to the first access network device. In this case, the second access network device may send the first message to the first access network device through the Xn/X2 interface. For example, in a handover scenario, the second access network device may carry the second message in the handover request confirmation HANDOVER REQUEST ACKNOWLEDGE message, and send it to the first access network device.

Manner 2, the second access network device sends the second message to the first access network device through the core network element. Specifically, the second access network device sends the first message to the core network element, and the core network element directly carries the second message in the handover request response message and forwards it to the first access network device. Alternatively, the core network device may process the second message first, and forward the processed second message in the handover request response message to the first access network device. For example, the core network element may be an AMF.

The above is only an example for the second access network device to send the second message, and the embodiment of the present application does not limit the manner in which the second access network device sends the second message to the first access network device. For example, the second access network device may send the second message to the first access network device through multiple network elements or devices.

Exemplarily, the second message is used to indicate at least one second AI service and/or at least one third AI service; the at least one second AI service is included in the at least one first AI service, and AI services supported by the second access network device; the at least one third AI service is an AI service included in the at least one first AI service and not supported by the second access network device.

Exemplarily, the second message includes configuration information of the at least one second AI service, and/or configuration information of the at least one third AI service. The configuration information of the at least one second AI service may include service information and/or capability configuration information of each second AI service, and the configuration information of the at least one third AI service may include the service of each third AI service information and/or capability configuration information.

Step 203: After receiving the second message, the first access network device sends a third message to the user equipment.

Correspondingly, the user equipment receives the third message from the first access network device.

In some embodiments, the first access network device may send the third message to the user equipment in the following manner:

Manner 1, the first access network device directly sends the third message to the user equipment. For example, in a handover scenario, the first access network device may carry the third message in a radio resource control (Radio Resource Control, RRC) reconfiguration message, and send it to the user equipment.

Manner 2: The first access network device sends the third message to the user equipment through a gateway device (eg, Customer Premise Equipment (CPE)).

The above is only an example for the first access network device to send the third message, and the embodiment of the present application does not limit the manner in which the first access network device sends the third message to the user equipment. For example, in a vehicle wireless communication technology scenario, the first access network device may send the third message to the user equipment on the sidelink through other user equipment.

Exemplarily, the third message is used to indicate at least one third AI service, and the at least one third AI service is an AI service included in at least one first AI service and not supported by the second access network device, The at least one first AI service is an AI service maintained by the first access network device and supported by the user equipment.

Exemplarily, the third message may include configuration information of the at least one third AI service, and the configuration information of the at least one third AI service may include service information of the third AI service. The at least one third AI service is explicitly indicated at this time.

Exemplarily, if the second message includes configuration information of the at least one second AI service and configuration information of the at least one third AI service, the configuration information of the at least one third AI service may only include at least one first AI service. The configuration information of the second AI service, the configuration information of the at least one second AI service may not include the configuration information of the at least one third AI service, but only the service information and/or capability configuration of each second AI service information, the at least one third AI service is implicitly indicated at this time by explicitly indicating at least one second AI service.

Step 204: After receiving the third message, the user equipment applies the configuration information of the at least one third AI service.

Further, in some embodiments, the user equipment executes the third AI service after applying the configuration information of the at least one third AI service. For example, the user equipment may send the data of the third AI service to the second access network device.

For example, the second access network device does not support the AI service being executed in the user equipment, which will cause service interruption of the AI service of the user equipment; when the service interruption occurs, the user equipment needs to adjust the configuration information of this part of the AI service For example, stop monitoring, collect, process, and transmit measurement information related to interrupting AI services, reduce resource consumption of user equipment, and prevent invalid data uploading from occupying air interface resources, resulting in waste of resources.

For example, in the case where the first access network device sends the first message to the second access network device through the core network element (for example, through the NG interface), the communication method of the embodiment of the present application is as shown in FIG. 3 . can include the following steps:

Step 301, the first access network device sends a first message to a core network element.

Exemplarily, the first message is used to indicate at least one first AI service, where the at least one first AI service is an AI service maintained by the first access network device and supported by the user equipment.

Step 302: After receiving the first message, the core network element sends the first message to the second access network device.

Exemplarily, the core network element may choose to process or not process the first message, and send the first message in a HANDOVER REQUIRED message carried by the handover request.

Step 303: After receiving the first message, the second access network device sends the second message to the core network element.

Exemplarily, the second message is carried in the HANDOVER REQUEST ACKNOWLEDGE message.

Step 304, the core network element receives the second message, and sends the second message to the first access network device.

For example, the core network element may or may not process the second message, and then send the first message in the HANDOVER COMMAND message.

Step 305: After receiving the second message, the first access network device sends a third message to the user equipment.

Exemplarily, the third message is carried in the RRC reconfiguration message.

Step 306, after receiving the third message, the user equipment applies the configuration information of at least one third AI service indicated by the third message.

In some embodiments, after applying the configuration information of at least one third AI service, the user equipment may send a third message to the second access network device.

Exemplarily, the fourth message may be carried in an RRC reconfiguration complete RRC Reconfiguration Complete message.

It can be seen that, in this example, the system supports the core network equipment to participate in the message exchange to realize the configuration adjustment of the AI service during the cell handover process.

It should be noted that the execution of the AI service described in the embodiments of this application is also referred to as application, use, participation, etc., which all refer to the transmission of data corresponding to the AI service by the user equipment and the network side equipment to support the corresponding AI service. network function.

In some embodiments, the third message is further used to indicate at least one fourth AI service and configuration information of the fourth AI service, where the at least one fourth AI service is the at least one second AI service AI business included in;

The method further includes: applying, by the user equipment, the configuration information of the at least one fourth AI service.

Exemplarily, the at least one fourth AI service is an AI service included in the at least one second AI service and requiring configuration update. In order to ensure the normal execution of the fourth AI service, the second access network device needs the user equipment to correspondingly adjust the configuration information of the fourth AI service.

Exemplarily, the third message may include service information and capability configuration information of each fourth AI service.

It can be seen that in this example, the fourth AI service that the system updates the configuration information according to the needs of the user equipment and is supported by the second access network device can be implemented through message interaction between the first access network device and the second access network device The user equipment is instructed to configure the fourth AI service through the third message, so as to avoid abnormality of the fourth AI service due to the failure to adapt and update the configuration in time during cell handover, and improve the stability of the system supporting the fourth AI service.

In this possible example, the second message is further used to indicate configuration information of the at least one fourth AI service.

Exemplarily, the second message may include configuration information of each fourth AI service.

It can be seen that, in this example, the system supports indicating the configuration information of at least one fourth AI service through the second message, so that the first access network device does not need to further interact to obtain the configuration information of the fourth AI service, thereby improving system performance.

In some embodiments, the third message is further used to indicate at least one fifth AI service, the at least one fifth AI service is included in the at least one third AI service, and the user equipment has a service AI business for continuity needs.

Exemplarily, the fifth AI service is the AI service of the user equipment in the third AI service that is not supported by the second access network device but has a service continuity requirement.

Specifically, the second access network device needs to record the address, port and other information of the first access network device for the fifth AI service (the second access network device can use the Xn/X2 interface to record the relevant data of the fifth AI service forwarded to the first access network device for further processing).

Further, in some embodiments, the second access network device determines to support the fifth AI service in the following manner.

Mode 1, the agreement stipulates that the data of the fifth AI service is supported by default according to the agreement. In this case, the second message may not make a special instruction for the fifth AI service, that is, it is maintained with the instruction mode of the second AI service. Consistent. The third message may carry indication information that supports the fifth AI service (for example: service information of the fifth AI service, capability configuration information, service identifier, service name, etc.) to explicitly instruct the user equipment to continue executing the fifth AI service, or, The third message may not carry the indication information of the fifth AI service to implicitly instruct the user equipment to continue executing the fifth AI service.

Mode 2, the second access network device independently decides to support the data transfer of the fifth AI service. In this case, the second message may carry indication information for supporting the fifth AI service, and the third message may carry indication information for supporting the fifth AI service (for example: service information, capability configuration information, service identifier, service name, etc.) to explicitly instruct the user equipment to continue to execute the fifth AI service, or the third message may not carry the indication information of the fifth AI service to implicitly instruct the user equipment to continue to execute the fifth AI service.

Manner 3: The first access network device inquires of the second access network device, so as to prompt the second access network device to determine to support the fifth AI service. In this case, the second message may carry indication information for supporting the fifth AI service, and the third message may carry indication information for supporting the fifth AI service (for example: service information, capability configuration information, service identifier, service name, etc.) to explicitly instruct the user equipment to continue to execute the fifth AI service, or the third message may not carry the indication information of the fifth AI service to implicitly instruct the user equipment to continue to execute the fifth AI service.

Mode 4, the first access network device independently decides to support the fifth AI service, if the first access network device does not receive the support information for the fifth AI service from the second access network device in the received second message , the first access network device notifies the second access network device to support the forwarding of the fifth AI service and record the forwarding address for the user equipment, etc., the first access network device sends a third message to the user equipment, and the third message can carry The indication information supporting the fifth AI service (for example, the service information, capability configuration information, service identifier, service name, etc. of the fifth AI service) is used to explicitly instruct the user equipment to continue to execute the fifth AI service, or it can be used in the third message. does not carry the indication information of the fifth AI service to implicitly instruct the user equipment to continue executing the fifth AI service.

It can be seen that in this example, the system can instruct the user equipment to continue to execute the fifth AI service through the third message for the AI service of the user equipment that is not supported by the second access network equipment but has continuity requirements, thereby improving the system's support for the AI service. stability.

In this possible example, the second message is used to indicate at least one second AI service and/or at least one third AI service, including: the second message is also used to indicate the at least one fifth AI service service, and/or at least one sixth AI service, where the at least one sixth AI service is an AI service included in the at least one third AI service and the user equipment has no service continuity requirement.

For example, for the sixth AI service that has no service continuity requirement, the user equipment no longer participates in the sixth AI service, and stops using capability configuration information and uploading related data.

Exemplarily, for the fifth AI service requiring service continuity, the second access network device does not support the fifth AI service, the first access network device configures the user equipment in the RRC reconfiguration message to continue to apply the capability configuration information, and executes The fifth AI service; the second access network device needs to record the address of the first access network device for the user equipment; after the user equipment completes the cell handover, continue to apply the capability configuration information of the fifth AI service, and upload the information related to the fifth AI service. data; the second access network device needs to forward the data uploaded by the user equipment to the first access network device, so that the fifth AI service can maintain service continuity.

If the second message fed back by the second access network device only includes indication information for indicating the fifth AI service (for example: information indicating that the second access network device supports the fifth AI service, information indicating that the second access network device supports the fifth AI service, does not support the information of the fifth AI service, the service information of the fifth AI service, the service identifier, etc.), the second message may implicitly indicate the sixth AI service. This situation corresponds to the determination by the second access network device that the user equipment needs to continue to perform the fifth AI service.

If the second message fed back by the second access network device only includes indication information for indicating the sixth AI service (for example: information indicating that the second access network device supports the sixth AI service, service information of the sixth AI service , service identifier, etc.), the second message may implicitly indicate the fifth AI service. This situation corresponds to the determination by the first access network device that the user equipment needs to continue to perform the fifth AI service.

If the second message fed back by the second access network device includes indication information for indicating the fifth AI service and indication information for indicating the sixth AI service, the second message may explicitly indicate the fifth AI service and the sixth AI service. Six AI business.

It can be seen that in this example, the system can indicate through the second message for the fifth and sixth AI services with different service continuity requirements, so that the first access network device can make it clear that the second access network device is for the two differentiated services. The support status of AI services can be accurately indicated to the user equipment, improving the stability of the system supporting AI services.

In some embodiments, the second message is further used to indicate at least one seventh AI service and configuration information of the at least one seventh AI service, where the at least one seventh AI service is the second access AI services that are supported by the network equipment and need to be added by the user equipment.

The method further includes: applying, by the user equipment, the configuration information of the at least one seventh AI service.

Exemplarily, the additional execution refers to that the user equipment does not execute the cell handover before the cell handover, and the second access network device requires the user equipment to execute. The at least one seventh AI service and the at least one first AI service may be different or the same, which is not uniquely limited herein.

It can be seen that in this example, the system supports synchronization to the first access network device through the second message for the AI service that the second access network device needs the user equipment to perform after cell handover, thereby improving system performance.

In this possible example, the third message is further used to indicate the at least one seventh AI service and configuration information of the at least one seventh AI service.

It can be seen that, in this example, the system supports synchronization to the user equipment through the third message for the AI service that the second access network device needs the user equipment to execute after the cell handover, thereby improving the system performance.

c) AI services that are not supported by the second access network device, that is, the user equipment no longer performs these AI services, and needs to stop using related configuration information and uploading related data; (AI services that require service continuity require special consideration)

d) The second access network device has an AI service that needs to be executed by the user equipment, and indicates in the response message that the user equipment needs to increase the execution of the AI service and the configuration information used by the AI service;

Step 1104: After receiving the HANDOVER REQUEST ACKNOWLEDGE message, the core network element sends a HANDOVER COMMAND message to the first access network device.

Exemplarily, the HANDOVER COMMAND message carries the response message.

Step 1105, after receiving the HANDOVER COMMAND message of the core network element, the first access network device sends an RRC Reconfiguration message to the user equipment according to the HANDOVER COMMAND message.

Exemplarily, the corresponding situation between the indication content of the RRC Reconfiguration message and the response message includes at least one of the following:

a) For the AI service supported by the second access network device in the response message, the sent RRC reconfiguration message may not be modified or reflected;

b) For AI services that are supported by the second access network device in the response message but need to update the configuration information, in the sent RRC reconfiguration message, the user equipment is notified according to the relevant user equipment indicated by the second access network device.

c) For AI services that are not supported by the second access network device in the response message, in the sent RRC reconfiguration message, instruct the user equipment to stop continuing to execute the relevant AI service, stop using the configuration information at the relevant user equipment, and stop uploading the relevant data ;

d) For the AI service indicated by the second access network device in the response message, in the sent RRC reconfiguration message, the user equipment is notified to execute the relevant AI service, the configuration information at the relevant user equipment is delivered, and the user equipment is notified to apply the AI service. configuration information;

Step 1106, after receiving the RRC reconfiguration message, the user equipment adjusts the configuration information of the executed AI service according to the information included in the RRC reconfiguration message.

The configuration information of the device realizes the efficient use of user device resources, improves the utility of air interface resources, and ensures the service continuity of AI services.

d) For the AI service for which the user equipment has service continuity requirements, if the second access network device does not support the AI service, the second access network device still indicates in the response signal that the AI service is supported, and records the AI service for the user equipment. Information such as the address and port of the first access network device;

e) The second access network device has new requirements for AI services, and indicates in the response message that the user equipment needs to perform related AI services and use related configuration information;

Step 1203, after receiving the HANDOVER REQUEST ACKNOWLEDGE message, the first access network device adjusts the RRC Reconfiguration message sent to the user equipment, adjusts the user equipment's execution of the AI service and related configuration information, and sends the RRC Reconfiguration message to the user equipment.

d) For AI services that are not supported by the second access network equipment and require service continuity:

If the first access network device independently determines the AI service, and the response message does not contain information about the support of the fifth AI service by the second access network device, the first access network device notifies the second access network device to support the AI The forwarding of the service and the recording of the forwarding address for the user equipment, etc., and the first access network device carries the indication information of supporting the AI service in the RRC reconfiguration message sent to the user equipment (for example: service information of the AI service, capability configuration information, service identifier, service name, etc.) to explicitly instruct the user equipment to continue to execute the fifth AI service, or, without carrying the indication information of the AI service, to implicitly instruct the user equipment to continue to execute the fifth AI service;

If the second access network device independently decides to support the data transfer of the AI service, and indicates in the response message to support the AI service, and records the address, port and other information of the first access network device for the user equipment, the first access network device will The network access device can choose not to indicate the following information in the RRC reconfiguration message: the user equipment continues to perform the AI service and uses the original configuration information, that is, the indication method that is consistent with the situation a) in this step 1203, that is, in the RRC reconfiguration message. The configuration message does not carry the indication information of the AI service to implicitly instruct the user equipment to continue executing the AI service; alternatively, the first access network device may choose to carry the indication information of the fifth AI service in the RRC reconfiguration message (for example, : the service information, capability configuration information, service identifier, service name, etc. of the fifth AI service to explicitly instruct the user equipment to continue executing the fifth AI service;

e) For the AI service indicated by the second access network device in the response message, the first access network device notifies the user equipment to execute the relevant AI service in the RRC reconfiguration message sent to the user equipment, and delivers the relevant user equipment The configuration information at the location, notify the user equipment to apply the configuration information;
