US 2020/0052919 A1 · Evolved Multimedia Broadcast/Multicast Service (EMBMS) System and EMBMS System Management Method

Abstract

Embodiments of the present disclosure provide an eMBMS system that includes a GW-C device connected to a mobility management entity and broadcast/multicast service center and a GW-U device connected to a base station and the mobility management entity. The GW-C device is configured to perform core network signaling interaction with the broadcast/multicast service center and the mobility management entity, and to send a forwarding indication message to the GW-U device. The GW-U device is configured to receive signaling from the base station and send the signaling to the GW-C device according to the forwarding indication message. The GW-C device is further configured to receive and process the signaling from the GW-U device. The GW-U device is further configured to send a received broadcast/multicast service data packet to the base station according to the forwarding indication message.
