[0018] The target encoding model information and the base station communication information that supports communication via encoding / decoding model are added to the handover request response message, and the handover request response message is sent to the source base station.

[0019] In the above communication method, after determining the base station communication type of the target base station, the method further includes:

[0020] If it is determined that the base station communication type of the target base station does not support communication via codec model, then the base station communication information that does not support communication via codec model is added to the handover request response message, and the handover request response message is sent to the source base station.

[0021] Thirdly, embodiments of this application provide a source base station, the base station comprising:

[0022] The first acquisition unit is used to send a handover request to the target base station, receive a handover request response message sent by the target base station, and acquire base station communication information from the handover request response message.

[0023] The first acquisition unit is further configured to acquire target encoding model information from the handover request response message if the base station communication information is information that the target base station supports encoding and decoding model communication;

[0024] The first sending unit is used to send an RRC reconfiguration message carrying the target coding model information to the terminal, so that the terminal can determine the target coding model for communicating with the target base station based on the target coding model information.

[0025] Fourthly, embodiments of this application provide a target base station, which stores preset communication model pair information, and the base station includes:

[0026] The determining unit is configured to determine the base station communication type of the target base station upon receiving a handover request from the source base station; the handover request carries the current encoding model information of the terminal.

[0027] The second acquisition unit is used to acquire the current encoding model information from the handover request if it is determined that the base station communication type of the target base station supports communication through the encoding and decoding model.

[0042] Existing downlink channel compression feedback based on artificial intelligence (AI) communication models requires cooperation between the terminal and the base station, namely the cooperation between the encoding network model on the terminal side and the decoding network model on the base station side.

[0043] Specifically, after the terminal and the base station negotiate the AI ​​coding model and AI decoding model required for downlink channel feedback, the base station periodically sends CSI-RS. After receiving the CSI-RS, the terminal performs channel estimation, compresses and quantizes the data using the coding model, and sends the compressed channel information back to the terminal. After receiving the compressed channel information, the base station decompresses it according to the negotiated AI decoding model to obtain complete downlink channel estimation information.

[0044] However, the terminal may encounter the following problems when switching between base stations:

[0045] (1) When there are decoding network models that support and do not support AI among the candidate base stations for switching, how to select the base station for switching.

[0046] (2) How to inform the terminal when the target base station after the handover has an updated encoding and decoding network model.

[0047] (3) How to roll back when the target base station after the switch does not support the AI ​​decoding network model.

[0048] Based on the above problems, this application provides a communication method that, when there are decoding network models that support and do not support AI among the candidate base stations during handover, the source base station can better select the target base station through inter-base station node configuration updates, and when the target base station after handover does not support the decoding network model of AI, the network can promptly notify the terminal to perform a fallback.

[0049] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit the scope of this application.

[0050] This application provides a communication method applied to a source base station. Figure 1 A communication method flow provided in the embodiments of this application Figure One ,like Figure 1 As shown, the communication method may include:

[0051] S101. Send a handover request to the target base station and receive the handover request response message sent by the target base station, and obtain the base station communication information from the handover request response message.

[0052] In this embodiment of the application, the source base station sends a handover request to the target base station and receives a handover request response message sent by the target base station, and obtains base station communication information from the handover request response message.

[0053] It should be noted that when the source base station receives the measurement report sent by the terminal, it sends a handover request to the target base station.

[0054] It should be noted that the measurement report consists of measurement parameters of at least one base station within a preset range centered on the terminal, used to characterize the communication capabilities of the base station.

[0055] It should be noted that, in the embodiments of this application, when the source base station sends a handover request to the target base station, it can send it through the network interface Xn. If the target base station does not support sending through Xn, the source base station can send the handover request to the core network element, such as the network protocol (Action Message Format, AMF), and the AMF will then forward the handover request to the target base station.

[0056] It should be noted that, in the embodiments of this application, the handover request sent by the source base station to the target base station carries the current encoding model information of the terminal and the current decoding model information of the terminal access base station, so that the target base station can determine the target communication model information for communication between the target base station and the terminal based on the current encoding model information, the current decoding model information and the preset communication model information stored by the target base station.

[0057] It should be noted that base station communication information refers to information that characterizes the communication type of the target base station.

[0058] It should be noted that there are two types of base station communication information: one type supports communication through the codec model, indicating that the target base station supports communication through the codec model; the other type does not support communication through the codec model, indicating that the target base station does not support communication through the codec model.

[0059] S102. If the base station communication information is information that the target base station supports for codec model communication, then obtain the target coding model information from the handover request response message.

[0060] In this embodiment of the application, after the source base station obtains the base station communication information, if the base station communication information is information that the target base station supports for codec model communication, then the target codec model information is obtained from the handover request response message.

[0061] It should be noted that if the target base station determines that its base station communication type supports communication via codec model after receiving the handover request, then the target base station determines the target codec model information for communicating with the terminal based on the current encoding model information in the handover request and the preset communication model information stored on the target base station. The target base station then adds the target decoding model information and the base station communication information that supports codec model communication to the handover request response message and sends it to the source base station. Therefore, if the source base station determines that the base station communication information in the handover request response message supports communication via codec model, it can obtain the target encoding model information from the handover request response message.

[0062] S103. Send an RRC reconfiguration message carrying target coding model information to the terminal so that the terminal can determine the target coding model for communicating with the target base station based on the target coding model information.

[0063] In this embodiment of the application, after the source base station obtains the target coding model information, it sends an RRC reconfiguration message carrying the target coding model information to the terminal, so that the terminal can determine the target coding model for communicating with the target base station based on the target coding model information.

[0064] In this embodiment of the application, the target coding model information includes the coding model identifier and coding model version number corresponding to the target coding model.

[0065] It should be noted that the RRC reconfiguration message includes target encoding model information. After receiving the RRC reconfiguration message, the terminal obtains the target encoding model information from the RRC reconfiguration message and compares the target encoding model information with its own current encoding model information. If the target encoding model information is the same as the current encoding model information, it means that the current encoding model on the terminal is the target encoding model corresponding to the target encoding model information, and the encoding model on the terminal does not need to be changed; if the target encoding model information is different from the current encoding model information, the encoding model on the terminal needs to be updated to the target encoding model corresponding to the target encoding model information.

[0066] In another optional embodiment of this application, if the base station communication information is information that the target base station does not support codec model communication, then the Channel State Information (CSI) communication configuration information is sent to the terminal so that the terminal can fall back to the first CSI communication mechanism according to the CSI communication configuration information; the first CSI communication mechanism is a mechanism that does not communicate through the codec model.

[0067] It should be noted that if the target base station determines from the handover request that its base station communication type does not support communication via the codec model, then the target base station will add the base station communication information that does not support codec model communication to the handover request response message and send it to the source base station.

[0068] It should be noted that when the source base station determines that the target base station does not support communication through the codec model based on the base station communication information, it sends the CSI feedback configuration information to the terminal. After receiving the CSI feedback configuration information, the terminal falls back to the first CSI communication mechanism, that is, the mechanism that does not communicate through the codec model.

[0069] In this embodiment, the source base station receives a node configuration update request sent by the target base station and obtains the preset communication model pair information supported by the target base station from the node configuration update request; so that the source base station can select the target base station according to the preset communication model pair information when performing base station handover.

[0070] This application provides a communication method applied to a source base station. The method includes: sending a handover request to a target base station and receiving a handover request response message from the target base station; obtaining base station communication information from the handover request response message; if the base station communication information is information that the target base station supports codec model communication, then obtaining target coding model information from the handover request response message; sending an RRC reconfiguration message carrying the target coding model information to a terminal, so that the terminal can determine the target coding model for communicating with the target base station based on the target coding model information. By adopting the above implementation scheme, the communication path to be used when the two base stations communicate and the target codec model when using codec model communication can be determined before the terminal switches base stations. Therefore, the communication capability of the terminal is not affected after the terminal switches base stations, thereby improving the user experience when the user uses the terminal for communication.

[0071] This application provides a communication method applied to a target base station. Figure 2 A communication method flow provided in the embodiments of this application Figure Two ,like Figure 2 As shown, the communication method may include:

[0072] S201. Upon receiving a handover request from the source base station, determine the base station communication type of the target base station; the handover request carries the terminal's current coding model information.

[0073] In this embodiment of the application, when the target base station receives a handover request sent by the source base station, it determines the base station communication type of the target base station; the handover request carries the current encoding model information of the terminal.

[0074] It should be noted that there are two types of base station communication for the target base station: one supports communication through a codec model, and the other does not support communication through a codec model.

[0075] S202. If it is determined that the base station communication type of the target base station supports communication through the encoding and decoding model, the current encoding model information and the current decoding model information are obtained from the handover request, and the target communication model information for communication with the terminal is determined according to the preset communication model pair information and the current encoding model information.

[0076] In this embodiment of the application, after determining the base station communication type, if the target base station determines that the base station communication type supports communication through the encoding and decoding model, it obtains the current encoding model information and the current decoding model information from the handover request, and determines the target communication model information for communicating with the terminal based on the preset communication model pair information and the current encoding model information.

[0077] It should be noted that the target base station compares the current encoding model information with the preset communication model pair information, selects the optimal encoding / decoding model pair information as the target communication model information, and sends the target decoding model information in the target communication model information to the source base station through a handover request response message.

[0078] S203. Add the target encoding model information and the base station communication information that supports communication via encoding / decoding model from the target communication model information to the handover request response message, and send the handover request response message to the source base station.

[0079] In this embodiment of the application, after determining the target communication model information, the target base station adds the target encoding model information and the base station communication information that supports communication through the encoding and decoding model to the handover request response message, and sends the handover request response message to the source base station.

[0080] It should be noted that the target base station sends a handover request response message containing target coding model information and base station communication information that supports coding and decoding model communication to the source base station. The source base station then determines the base station communication type of the target base station based on the base station communication information in the handover request response message, and then sends different information to the terminal according to the different base station communication types.

[0081] In another optional embodiment of this application, if it is determined that the base station communication type of the target base station does not support communication via the codec model, the base station communication information that does not support communication via the codec model is added to the handover request response message, and the handover request response message is sent to the source base station.

[0082] It should be noted that if the base station communication type is not supported via codec model communication, it means that if the terminal wants to establish a communication connection with the target base station, it cannot use the codec model communication method and needs to use the traditional CSI communication mechanism.

[0083] This application provides a communication method applied to a target base station. The method includes: upon receiving a handover request from a source base station, determining the base station communication type of the target base station; the handover request carrying the current encoding model information of the terminal; if the base station communication type of the target base station is determined to support communication via encoding / decoding model, obtaining the current encoding model information from the handover request, and determining the target communication model information for communication with the terminal based on preset communication model pair information and the current encoding model information; adding the target encoding model information and the base station communication information supporting communication via encoding / decoding model from the target communication model information to the handover request response message, and sending the handover request response message to the source base station; by adopting the above implementation scheme, the communication path to be used for communication between the two base stations and the target encoding / decoding model when using encoding / decoding model for communication can be determined before the terminal switches base stations, so that the communication capability of the terminal is not affected after the terminal switches base stations, thereby improving the user experience when the user uses the terminal for communication.
