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: Embodiments of this application provide a message forwarding method and an apparatus, so that a message for joining a multicast group is sent to a multicast user plane network element, and the multicast user plane network element is triggered to establish a tunnel for transmitting multicast data between the multicast user plane network element and an application server. The method may include: a multicast session management network element receives the message that indicates that a terminal is joining the multicast group; and when the terminal is the 1st terminal the multicast group, sends, to the multicast user plane network element, a message that requests to establish the tunnel for transmitting the multicast data between the multicast user plane network element and the application server.

Abstract: In a method, a first transmission server determines, based on first quality of service measurement information and/or first quality of service monitoring information, that the first transmission server is to be switched, and determines a second transmission server. Quality of service of serving by the second transmission server connected to the first transmission client via the first access network device and a second user plane function network element satisfies a quality of service requirement of an application layer application. In other words, the first transmission server may determine, based on QoS information obtained through measurement and UE-RAN QoS information, RAN-UPF QoS information, or UE-RAN-UPF QoS information obtained through 5GC monitoring, whether the first transmission server is to be switched. In addition, the first transmission server may determine the second transmission server that satisfies the QoS requirement, so that the first transmission server can be switched to the second transmission server.

Abstract: Embodiments of this application provide a communication method, a communication apparatus, and a communication system. A proxy client of a terminal device receives application data traffic from an application client of the terminal device; the proxy client determines first data traffic and second data traffic based on the application data traffic, and the first data traffic, the second data traffic, and the application data traffic include same data; and the proxy client sends the first data traffic to a proxy server by using a first session, and sends the second data traffic to the proxy server by using a second session, where the first session and the second session are redundant sessions for each other. In this solution, the proxy client and the proxy server implement redundant transmission of the application data traffic, to ensure correctness and reliability of data transmission, and help improve user experience.

Abstract: This application provides a network slice-based communication method and an apparatus to improve a success rate of accessing a network slice by a terminal. A network device determining, by a network device, a network slice that a terminal is allowed to access and a network slice that the terminal is rejected to access; determines a registration area of the terminal based on the network slice that the terminal is allowed to access and the network slice that the terminal is rejected to access; and sends information about the registration area to the terminal.

Abstract: Example methods, devices, and apparatuses are discussed. An example method includes determining that a condition associated with triggering a registration procedure is satisfied. The condition comprises that a second tracking area (TA) supports a first slice. The second TA belongs to a current registration area (RA) of the terminal device. The first slice is rejected in the current RA, wherein the terminal device is in the second TA. The example method further includes,n response to the determination, sending a second registration request message to a core network device. The second registration request message requests to access the first slice. The second registration request message comprises information about the first slice.
