Abstract
In an embodiment, a server determines a first support state for the group communication session that defines a first set of sectors belonging to a multicast/broadcast single frequency network (MBSFN) area for transmission of the session media for the group communication session via Internet Protocol (IP) multicast. The server then transitions the group communication session from the first support state to a second support state that defines a second set of sectors belonging to the MBSFN area for transmission of the session media for the group communication session via IP multicast. Before the transition, the server delivers the session media to the first set of sectors via IP multicast in accordance with the first support state. After the transition, the server delivers the session media to the second set of sectors via IP multicast in accordance with the second support state.
