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 technology of this application relates to a communication method and a communication apparatus used for positioning. The method includes a positioning device sending a request to an access network device, where the request is used to request information about a cell type of the access network device, and the cell type includes an indoor cell or an outdoor cell, or the cell type includes any one of: a macro cell, a micro cell, or a lampsite cell. The positioning device receives the information about the cell type from the access network device. The request may be sent to the access network device by using a transmission reception point (TRP) information request message, and the information about the cell type may be received by using a TRP information response message.
