An evolved multimedia broadcast / multicast service (eMBMS) cluster management

摘要

In one embodiment, the server (e.g., an application server), Internet Protocol (IP) transmission session media for group communication sessions via multicast (925A, 930A) with respect to the multicast / broadcast single frequency network first set of sectors belonging to (MBSFN) area (for example, cluster) to determine a first support state on the group communication session to define the (920A). The server then, the group communication session, from the first support state, the transmission of session media for group communication sessions over an IP multicast (915C, 920C) a second set of sectors belonging to the MBSFN area in relation to to define the (910C) is shifted to the second support state (910C). Before migration, the server delivers the session media in the first set of the sector through the IP multicast by the first support state (925A, 930A). After migration, the server delivers the session media to the second set of the sector through the IP multicast by the second support state (915C, 920C).
