Abstract: A data buffering method including: a session management function (SMF) interacting with a first user plane function (UPF1) and a second UPF2, such that the UPF1 sends first downlink data of a first session to an access network device via UPF2, where UPF1 is an anchor of the first session; and the SMS releasing UPF2 in a procedure in which a terminal device enters an idle state and a transmission resource associated with the first session in an access network is released, where UPF1 buffers incoming second downlink data of the first session. After the terminal device is switched to a connected state, both a transmission path of incoming third downlink data of the first session and that of the buffered second downlink data pass through UPF1, UPF3, the access network device, and the terminal device successively.

Abstract: A method includes: receiving, by a network element selector, a first message from a first external network element, where the first message carries a first session index, and the first session index is used to identify UE served by the first external network element; and sending, by the network element selector, the first message to a first converged controller based on mapping information corresponding to the UE and the first session index in the first message, where the mapping information includes a mapping relationship between the first converged controller and a plurality of different session indexes of the UE, and the plurality of different session indexes of the UE include the first session index. It can be learned that the network element selector sends, based on the mapping information corresponding to the UE, all messages of different external network elements serving the UE to a same converged controller.

Abstract: In a session management method, when a first access and mobility management function (AMF) network element serving a terminal becomes unavailable, a service management function (SMF) network element obtains a pool identifier of an AMF pool that includes the first AMF, and queries a network repository function (NRF) entity to obtain the address or identifier of a second AMF in the same AMF pool. The SMF then triggers the second AMF network element to obtain a context of the terminal from a unstructured data storage function (UDSF) entity.

Abstract: A communication event processing method includes obtaining, by a first terminal, a use status of the first terminal and a use status of a second terminal. The method includes determining either the first terminal or the second terminal as a communication event receiving terminal according to at least one of the use status of the first terminal or the use status of the second terminal. The method includes sending, by the first terminal, a communication event transfer start instruction message to a server when the communication event receiving terminal is the second terminal and a communication event receiving terminal determined last time is the first terminal, where the communication event transfer start instruction message is used to instruct the server to forward, to the second terminal, a received communication event to be sent to the first terminal.
