Abstract: Embodiments of this application provide a network handover method and a related device. The method includes: when receiving a user terminal handover request that is sent by a source radio access network node and that carries a target base station identifier, determining, by a source mobility management function entity based on the target base station identifier, to trigger inter-RAT network handover; sending a first message to a source session management function entity; receiving a second message sent by the source session management function entity, where the second message includes a session management context; and sending a relocation request to a target mobility management function entity, where the relocation request is used to instruct the target mobility management function entity to perform inter-RAT network handover on the user terminal. In this way, data continuity in an inter-RAT network handover process is ensured.

Abstract: This application provides a communication method, an apparatus, and a device. The method provides storage and/or selection of a correspondence between an edge application server (EAS) and a service enabler architecture layer data delivery (SEALDD) server, so that when performing EAS discovery and selection, an edge enabler server (EES) may simultaneously select the SEALDD server corresponding to the EAS. This facilitates collaborative use of an MEC service and a service enabler architecture layer data delivery service. In addition, in this method, information about the service enabler architecture layer data delivery service may be decoupled from registration information of the EAS, and another network element may be allowed to query a configuration server for the information about the service enabler architecture layer data delivery service. This helps simplify a service enabler architecture layer data delivery service procedure.

Abstract: Example uncrewed aerial vehicle communication methods and apparatus are described. One example method includes a first access network device receives indication information used to indicate access information of a next hop of the uncrewed aerial vehicle, where the access information includes at least one of information about a second access network device or information about a cell of a second access network device. The first access network device sends a first request based on the indication information, where the first request is used to request the second access network device to prepare an access resource for the uncrewed aerial vehicle. The second access network device prepares the access resource for the uncrewed aerial vehicle after receiving the first request.

Abstract: This application provides a service data transmission method and a communication apparatus. The method includes: An application server obtains first information of a multicast broadcast service session; and the application server sends data of a service over the multicast broadcast service session based on the first information. In the foregoing technical solution, the application server may determine, based on related information (for example, information of a terminal in the multicast broadcast service session, or information of the multicast broadcast service session) of the multicast broadcast service session, that the data of the service can be transmitted over the multicast broadcast service session. In this way, the data of the service can be transmitted flexibly over the multicast broadcast service session.

Abstract: This application discloses a communication method and a communications apparatus, to resolve problems of a long transmission path and a large transmission delay of signaling that are caused because a data network (DN) to which application layer control signaling used to control path switching needs to be transmitted for processing in a process of the path switching is outside a mobile communications network. The method includes receiving, by a first core network device, a request message from a terminal, where the request message is used to request to switch from a multicast mode to a unicast mode to transmit service data to be sent to the terminal. The method further includes indicating, by the first core network device based on the request message, a multicast user plane gateway and/or a service server corresponding to the terminal to send, to the terminal in the unicast mode, the service data to be sent to the terminal.
