Abstract: The present disclosure relates to data transmission methods and apparatus to implement quality of service (QoS) flow-based data transmission in an architecture in which a central unit-control plane (CU-CP) and a central unit-user plane (CU-UP) are separated from each other. In one example method, when receiving data of a QoS flow, the CU-UP may send a QoS flow identity (ID) and a protocol data unit (PDU) session ID that are of the data of the QoS flow to the CU-CP, where a PDU session corresponding to the PDU session ID includes the data of the QoS flow.

Abstract: Embodiments of the present invention propose a communication method. The communication method includes: obtaining, by a base station, DRB configuration information, where the DRB configuration information is used to determine a mapping relationship between serving cells and DRBs used to carry data of different service types; and sending the DRB configuration information to a terminal, so that the terminal communicates with the base station in a serving cell corresponding to a DRB. The embodiments of the present invention further disclose a base station and a terminal to which the communication method is applied.

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: A communication method and a communications device are provided. In the method, a first base station receives a first message; the first base station determines, based on the first message, whether to allocate a new RNA to a terminal in an inactive state; and the first base station allocates a new RNA to the terminal in the inactive state after determining to allocate a new RNA to the terminal in the inactive state, so as to reduce signaling overheads; and/or the first base station receives a second message; the first base station determines a communication status of the terminal in the inactive state based on the second message; and after determining that the terminal needs to change the communication status, the first base station controls the terminal to change the communication status.
