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.

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.
