Claim 0:
1. A mobility management method, applied to a scenario in which a first terminal device moves, the method comprising:
determining, by a control plane network element, a changed media access control (MAC) address of the first terminal device after the first terminal device moves;
determining, by the control plane network element, at least one second terminal device that belongs to a terminal device group as the first terminal device, wherein the first terminal device is a terminal device whose address changes after the movement, and the at least one second terminal device is a terminal device other than the first terminal device in the terminal device group; and
 notifying, by the control plane network element, the first terminal device and the at least one second terminal device to update to the changed MAC address of the first terminal device, wherein notifying the first terminal device to update to the changed MAC address of the first terminal device comprises:
sending, by the control plane network element, first address update information to the first terminal device through a first device, wherein the first address update information comprises the changed MAC address of the first terminal device, and the first device is one of a target access device serving the first terminal device after the first terminal device moves, a target user plane function network element serving the first terminal device after the first terminal device moves, and a target integrated device serving the first terminal device after the first terminal device moves, wherein the target integrated device is a device in which an access device and a user plane function network element are integrated.
