摘要： Aspects of de-registering a multicast group member from a multicast group within a wireless communications network are disclosed. An access terminal sends a first multicast registration message to an access network, with the first multicast registration message identifying a first set of multicast groups. The access network receives the first multicast registration message and registers the access terminal for each of the first set of multicast groups. The access terminal sends a second multicast registration message, the second multicast registration message omitting at least one multicast group from among the first set of multicast groups, the second multicast registration message being sent to request de-registration, for the access terminal, from at least one multicast group. The access network receives the second multicast registration message and interprets the second multicast registration message as a request to de-register the access terminal from the omitted at least one multicast group.
