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.
