    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.

    Abstract translation: 在一个实施例中,服务器确定组通信会话的第一支持状态,所述组通信会话定义属于多播/广播单频网络(MBSFN)区域的第一组扇区,用于经由因特网协议传输用于组通信会话的会话媒体 (IP)组播。 然后,服务器将组通信会话从第一支持状态转换到第二支持状态,该第二支持状态定义属于MBSFN区域的第二组扇区,用于经由IP多播传送用于组通信会话的会话媒体。 在转换之前,服务器根据第一支持状态通过IP多播将会话媒体传送到第一组扇区。 在转换之后,服务器根据第二支持状态通过IP多播将会话媒体传送到第二组扇区。
