Abstract: The present disclosure relates to communication methods and communication apparatus. In one example method, a centralized unit user plane (CU-UP) obtains a first service feature of a service. The first service feature includes one or more of the following: data that indicates whether the service is a periodic service, a periodicity corresponding to the service when the service is a periodic service, a service packet size corresponding to the service, a service model corresponding to the service, or scheduling time of the service. Then, the CU-UP sends the first service feature to a centralized unit control plane (CU-CP). Next, the CU-CP may send the first service feature to a distributed unit (DU).

Abstract: This application provides a radio resource management measurement method and apparatus. A network device sends measurement configuration information to a terminal device, where the measurement configuration information carries a first threshold; and the terminal device determines, based on a value relationship between a detection value and the first threshold, and signal quality of at least one neighboring cell, whether to report a measurement report. When performing RRM measurement, the terminal device can determine, based on a relationship between the first threshold and signal quality of a serving cell and/or a quantity of detected cells, and the signal quality of the at least one neighboring cell, whether to report the measurement report. This can prevent the terminal device from reporting the measurement report frequently, and avoid a case in which the terminal device does not report the measurement report in a timely manner, so that a measurement mechanism is more appropriate.

Abstract: An artificial intelligence (AI) protocol layer of a first access network device generates an AI parameter, and sends the AI parameter to a terminal device. Then, the first access network device receives, from the terminal device, AI data obtained based on the AI parameter. The AI protocol layer of the first access network device is an upper layer of a radio resource control (RRC) protocol layer of the first access network device, an AI protocol layer of the terminal device is an upper layer of an RRC protocol layer of the terminal device, and the AI parameter indicates the AI data that needs to be obtained and an AI data obtaining manner.

Abstract: Embodiments of this application provide a synchronization signal/physical broadcast channel block (SSB) measurement method and an apparatus. One example method includes that a terminal device receives first information and second information. The first information indicates a time domain position of an SSB sent by a serving cell, and the second information indicates a set of SSBs that the terminal device needs to measure and that are sent by a neighboring cell. The terminal device measures, in a first measurement window based on the first information, the SSB sent by the serving cell. The terminal device measures, in a second measurement window based on the second information, the SSB sent by the neighboring cell.

Abstract: Example cell measurement methods and apparatus are described. One example method includes obtaining, by a first network device, a first paging parameter of a cell served by a second network device. The first paging parameter is used to indicate a first time domain position at which a terminal device monitors a paging message from the second network device. The first network device sends a reference signal based on the first paging parameter. A time domain position of the reference signal is determined based on the first time domain position.

Abstract: A handover method includes obtaining, by a source base station and a target base station, first indication information. The first indication information indicates a time during which a terminal device separately transmits data with the source base station and the target base station when the terminal device is handed over from a first cell of the source base station to a second cell of the target base station. The first cell and the second cell are intra-frequency neighboring cells. The method also includes sending, by the source base station, the first indication information to the terminal device.

Abstract: Example communication methods and apparatus are described. One example method includes determining, by a terminal device, that a connection failure occurs between the terminal device and a first cell, where the first cell is a cell of a first network device. The terminal device determines signal quality of a second cell of a second network device, where both the first network device and the second network device provide communication services for the terminal device. If the signal quality of the second cell is greater than or equal to a first preset threshold, the terminal device performs a connection recovery process between the terminal device and the first cell by using the second cell.

Abstract: Embodiments of this application provide a communication method, apparatus, and system. The method includes: A terminal device receives first information from a first network device or a second network device, and determines, based on the first information, that it is allowable that the terminal device sends MDT information to the first network device. When it is allowable that the terminal device sends the MDT information to the first network device, the terminal device sends the MDT information to the first network device. This prevents the terminal device from sending the MDT information to the first network device immediately after obtaining the MDT information and avoids disclosure of a network coverage status, thereby effectively and securely using the MDT information.

Abstract: The present disclosure relates to communication methods and network devices. In one example method, a first network device receives a first message sent by a second network device, where the first message is used to notify whether the first network device configures a default data radio bearer (DRB), and the first network device and the second network device are network devices that provide a multi-connectivity service for a same terminal device. The first network device determines, based on the first message, whether to configure the default DRB.

Abstract: The present disclosure relates to mode switching methods, data flow splitting methods, and apparatus. One example mode switching method includes generating, by a first device, first indication information, where a packet data control protocol (PDCP) entity in the first device is connected to at least two radio link control (RLC) entities in a second device, and sending, by the first device, the first indication information to the second device, where the first indication information is used to indicate that transmission between a first RLC entity in the at least two RLC entities and the PDCP entity in the first device is to be canceled. The second device stops the transmission between the first RLC entity and the PDCP entity based on the first indication information.
