[0109] In recent years, artificial intelligence (AI) technology has achieved continuous breakthroughs in numerous fields. The continued development of fields like intelligent voice and computer vision has not only brought a rich variety of applications to smart terminals, but has also found widespread application in education, transportation, home living, healthcare, retail, security, and other fields. This has brought convenience to people's lives while also promoting industrial upgrades across various industries. AI technology is also rapidly intersecting with other disciplines, integrating knowledge from diverse disciplines while also providing new directions and methods for their development.

[0110] In related technologies, a research project on AI technology in wireless air interfaces has been established in the Radio Access Network (RAN) to introduce artificial intelligence technology into the wireless air interfaces and assist in improving the transmission technology of the wireless air interfaces.

[0111] According to relevant research on AI, AI application cases may include but are not limited to at least one of the following:

[0112] AI-based channel state information (CSI) enhancement;

[0113] AI-based beam management;

[0114] AI-based positioning.

[0115] AI / Machine Learning (ML) features are defined for AI-based operations. An AI feature can correspond to one or more AI functions, an AI function can correspond to one or more AI models, and an AI model can correspond to one or more AI functions.

[0116] For example, AI-based beam management can be an AI feature. The principle of AI-based beam management is to predict the channel information of all beams based on the channel information of some actual measurement beams. Therefore, the AI ​​function can be defined based on the number of actual measurement beams. For example, AI function #1 supports 16 or 32 actual measurement beams, and AI function #2 supports 64 actual measurement beams. Both AI functions belong to the AI ​​feature of AI-based beam management. It can be understood that the AI ​​model is the actual entity that performs AI operations, and the AI ​​function is an abstraction of the function implemented by the AI ​​model.

[0117] In some embodiments, at least one of the AI ​​features, AI functions, and AI models can be deployed on the terminal side. When at least one of the AI ​​features, AI functions, and AI models is deployed on the terminal side, the terminal can report the at least one of the AI ​​features, AI functions, and AI models supported by the terminal to the network device. When the terminal moves, such as during cell handover, there is no clear process for how to transmit relevant information of at least one of the AI ​​features, AI functions, and AI models.

[0118] FIG2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0119] Step S2101: The first base station sends fourth information to the core network device.

[0120] In some embodiments, the core network device receives fourth information sent by the first base station. The fourth information is used to query whether the second base station supports AI-based operations. The first base station is the base station to which the terminal is currently connected, and the terminal resides in the cell of the first base station. The second base station is the target base station for the terminal to switch, and optionally, the second base station is one of the target base stations to which the terminal is to switch. The first base station may be referred to as the source base station, and the second base station may be referred to as the target base station.

[0121] In some embodiments, the core network device includes a first network element, and the first base station sends the fourth information to the first network element. Optionally, the first network element receives the fourth information sent by the first base station. The first network element is, for example, an AMF, or may be another network element.

[0122] In some embodiments, step S2101 is an optional step. For example, it may be assumed that the second base station supports AI-based operations, or it may be assumed that the second base station does not support AI-based operations, or the core network device may actively send the second information to the first base station.

[0123] Step S2102: The core network device sends second information to the first base station.

[0124] In some embodiments, the first base station receives second information sent by a core network device. Optionally, the first base station receives second information sent by a first network element. The second information is used to indicate whether the second base station supports AI-based operations. Optionally, the second information is used to indicate that the second base station supports AI-based operations, or the second information is used to indicate that the second base station does not support AI-based operations. Optionally, the core network device may send the second information to the first base station based on the fourth information, or the core network device may proactively send the second information to the first base station.

[0125] In some embodiments, step S2102 is an optional step. For example, regardless of whether the second base station supports AI-based operations, the first base station sends the first information to the second base station.

[0126] According to the above embodiment, the first base station can interact with the core network device to confirm whether the second base station supports AI-based operations. When the second base station supports AI-based operations, the first base station sends the first information to the second base station to avoid resource waste.

[0127] Step S2103: The first base station sends first information to the second base station.

[0128] In some embodiments, the second base station receives the first information sent by the first base station.

[0129] In some embodiments, the first information is used to indicate at least one of the AI ​​features, AI functions, and AI models supported by the terminal.

[0130] In some embodiments, the first base station may send the first information to the second base station based on the second information. For example, if the second information indicates that the second base station supports AI-based operations, the first base station sends the first information to the second base station; if the second information indicates that the second base station does not support AI-based operations, the first base station does not send the first information to the second base station.

[0131] In some embodiments, the first base station may not send the first information to the second base station based on the second information. For example, the first base station needs to send the first information to the second base station by default.

[0132] According to the above embodiment, based on the terminal being connected to the first base station, when the terminal moves, for example, when switching cells, the first base station can transmit at least one of the AI ​​characteristics, AI functions and AI models supported by the terminal to the second base station. In this way, when switching cells, the terminal does not need to report the supported AI characteristics, AI functions or AI models to the second base station, saving air interface signaling overhead. In addition, optical fiber connections are used between base stations, and information transmission is very fast with low latency.

[0133] In some embodiments, the first information may be included in a first message, where the first message is a message carrying a handover request. After receiving the first message, the second base station may accept or reject the handover access request of the terminal. The second base station sends a handover request response message to the first base station. The handover request response message is a handover request confirmation message or a handover request rejection message.

[0134] In the cell switching process, the first base station needs to send a first message to the second base station to request switching from the second base station. According to the above embodiment, when the first base station sends the first message to the second base station, it can carry the above first information in the first message, so that the embodiment of the present disclosure can reuse the cell switching process.

[0135] In some embodiments, the first information may be included in user context information (UE context information) in the first message, or included in an information element (IE) different from the UE context information. If the first information is included in the IE of the UE context information, then the first information may be included in a radio resource control context (RRC context) message in the UE context information, or included in a message different from the RRC context. If the first information is included in the RRC context message, then the first information may be included in the terminal capability information (UE capabilityRAT-list) related to the radio access technology (RAT) in the RRC context, or included in an IE in the RRC context that specifically includes the AI ​​characteristics, AI functions, or AI models of the terminal, which IE is different from the UE capabilityRAT-list.

[0136] In some embodiments, the first information may be included in a second message, which is a message sent by the first base station to the second base station after receiving a handover request confirmation message from the second base station. Optionally, the second message may be a sequence number status transfer (SN STATUS Transfer) message.

[0137] In the cell switching process, after the second base station accepts the switching access of the terminal, the first base station needs to send a second message to the second base station for status or configuration transmission. According to the above embodiment, when the first base station sends the second message to the second base station, it can carry the above first information in the second message, so that the embodiment of the present disclosure can reuse the cell switching process.

[0138] In some embodiments, the names of information, etc. are not limited to the names described in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codeword", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0139] In some embodiments, "obtain", "get", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining by self-processing, autonomous implementation, etc.

[0140] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0144] Step S2201: The first base station sends fifth information to the second base station.

[0145] In some embodiments, the second base station receives the fifth information sent by the first base station. The fifth information is used to determine whether the second base station requires at least one of the AI ​​features, AI functions, and AI models supported by the terminal. The first base station is the base station to which the terminal is currently connected, and the terminal resides in the cell of the first base station. The second base station is the target base station to which the terminal is switching, and optionally, the second base station is one of the target base stations to which the terminal is switching. The first base station may be referred to as a source base station, and the second base station may be referred to as a target base station.

[0146] In some embodiments, step S2201 is optional.

[0147] Step S2202: The second base station sends third information to the first base station.

[0148] In some embodiments, a first base station receives third information sent by a second base station. The third information is used to indicate whether the second base station requires at least one of the AI ​​features, AI functions, and AI models supported by the terminal. Optionally, the third information is used to indicate that the second base station requires at least one of the AI ​​features, AI functions, and AI models supported by the terminal, or the third information is used to indicate that the second base station does not require at least one of the AI ​​features, AI functions, and AI models supported by the terminal.

[0149] In some embodiments, step S2202 is an optional step. For example, regardless of whether the second base station requires at least one of the AI ​​feature, AI function, and AI model supported by the terminal, the first base station sends the first information to the second base station.

[0150] According to the above embodiment, the first base station can interact with the second base station to confirm whether the second base station needs to receive at least one of the AI ​​features, AI functions and AI models supported by the terminal. When the second base station needs to receive at least one of the AI ​​features, AI functions and AI models supported by the terminal, the first base station sends the first information to the second base station to avoid waste of resources.

[0151] Step S2203: The first base station sends first information to the second base station.

[0152] In some embodiments, the second base station receives the first information sent by the first base station.

[0153] In some embodiments, the first information is used to indicate at least one of the AI ​​features, AI functions, and AI models supported by the terminal.

[0154] In some embodiments, the first base station may send the first information to the second base station based on the third information. For example, if the third information indicates that the second base station requires at least one of the AI ​​features, AI functions, and AI models supported by the terminal, the first base station sends the first information to the second base station; if the third information indicates that the second base station does not require at least one of the AI ​​features, AI functions, and AI models supported by the terminal, the first base station does not send the first information to the second base station.

[0155] In some embodiments, the first base station may not send the first information to the second base station based on the third information. For example, the first base station needs to send the first information to the second base station by default.

[0156] According to the above embodiment, based on the terminal being connected to the first base station, when the terminal moves, for example, when switching cells, the first base station can transmit at least one of the AI ​​characteristics, AI functions and AI models supported by the terminal to the second base station. In this way, when switching cells, the terminal does not need to report the supported AI characteristics, AI functions or AI models to the second base station, saving air interface signaling overhead. In addition, optical fiber connections are used between base stations, and information transmission is very fast with low latency.

[0157] In some embodiments, the first information may be included in a first message, where the first message is a message carrying a handover request. Alternatively, the first information may be included in UE context information in the first message.

[0158] In some embodiments, the first information may be included in a second message, which is a message sent by the first base station to the second base station after receiving a handover request confirmation message from the second base station.

[0203] In step S6101, the terminal performs measurement control, triggers a measurement report event, and then performs a measurement report (MR).

[0204] Step S6102: The source base station evaluates the measurement result reported by the terminal and decides whether to trigger handover.

[0205] In step S6103, if the source base station decides to trigger a handover, the source base station sends a first message to the target base station, where the first message is a message carrying a handover request.

[0206] In some embodiments, the first message may include first information, where the first information is used to indicate the AI ​​feature / AI functionality / AI model supported by the terminal. After the target base station receives the first message, the target base station may accept or reject the handover access of the terminal.

[0207] Specifically, the AI ​​feature / AI functionality / AI model supported by the terminal may be included in the IE of the UE context information, or in an IE different from the UE context information. If the AI ​​feature / AI functionality / AI model supported by the terminal is included in the IE of the UE context information, it may further be included in the RRC context message in the UE context information, or in a message different from the RRC context.

[0211] In some embodiments, the second message may include first information, where the first information is used to indicate the AI ​​feature / AI functionality / AI model supported by the terminal. That is, the first information may be included in the first message or the second message.

[0212] Step S6107: Handover is executed, for example, the terminal disconnects from the source base station and establishes synchronization with the target base station.
