Abstract: Example communication methods and apparatus are described. One example method includes sending a first handover request by a source base station to a core network device, where the first handover request is used to request to hand over a current session of a terminal from the source base station to any one of at least one base station, and the first handover request includes information about the at least one base station. The source base station receives a first handover response message from the core network device, where the first handover response message includes indication information, and the indication information is used to indicate whether a first base station of the at least one base station supports a network slice corresponding to the current session of the terminal device.
