Abstract
This application provides a communication method and a communication apparatus. In a technical solution of this application, when a preset condition is met, an access network device notifies user equipment that a multicast session is to be released or is to be deactivated. If the multicast session is being used or is to be used, the user equipment may feed back to the access network device that the user equipment is still interested in a multicast service. The access network device may determine, based on whether the feedback from the user equipment is received within a preset time period, whether to continue to release or deactivate the multicast session. In this way, when user equipment in an idle state can receive multicast data, this technical solution can properly manage the multicast session.
