Abstract
A communication method and apparatus. A first access network device determines that a first terminal device is a last terminal device that receives data of a first multicast service via the first access network device in response to the first terminal device being in a handover preparation phase in which the first terminal device is handed over from the first access network device to a second access network device. The first access network device sends first information that is used to release a first tunnel. The first tunnel is used to transmit the data of the first multicast service between the first access network device and a core network device.
