Abstract: This application provides an information transmission method when a terminal device accesses a serving radio access network (RAN) device. The terminal device receives an identifier of a first cluster-data function (C-DF) associated with the serving RAN device from the serving RAN device, where the first C-DF is located in a radio access network and stores current data of the terminal device. When the terminal device camps on the serving RAN device longer than or equal to a first threshold, the terminal device stores the identifier of the first C-DF.

Abstract: Implementations of this application provide communications methods, devices, and chips. In an implementation, a method comprises: sending, by a centralized unit user plane (CU-UP) of an access network to a centralized unit control plane (CU-CP) of the access network, an interface setup request message to request to setup an E1 interface, the interface setup request message comprises an identity of a public land mobile network (PLMN) served by the CU-UP and a network slice identifier corresponding to the public land mobile network, wherein the network slice identifier identifies single network slice selection assistance information (S-NSSAI) or an S-NSSAI list; and sending, by the CU-CP, an interface setup response message to the CU-UP after receiving the interface setup request message.

Abstract: Example communication methods and apparatus are described. One example method includes sending a handover request message to a target base station, where the handover request message is used to instruct to hand over a first session of a terminal device from the source base station to the target base station. The handover request message includes first information. The first information includes information about at least one quality of service (QoS) flow in the first session. The first session is a session corresponding to the terminal device. The source base station receives a handover request response message from the target base station, where the handover request response message includes second information. The second information is used to indicate that the target base station accepts a first QoS flow in the first session, and the at least one QoS flow includes the first QoS flow.

Abstract: The present disclosure relates to communication methods, base stations, terminal devices, and systems. One example method includes sending, by a master base station, a first request message to a secondary base station, where the first request message instructs the secondary base station to switch a first Quality of Service (QoS) flow of a first session from the secondary base station to the master base station, and the first session is a session corresponding to a terminal device, and receiving, by the master base station, a first response message from the secondary base station, where the first response message responds to the first request message.
