Evolved Multimedia Broadcast/Multicast Service (EMBMS) System and EMBMS System Management Method
First Claim
1. An evolved multimedia broadcast/multicast service (eMBMS) system, comprising:
- a broadcast/multicast service center;
a base station;
a mobility management entity configured to connect to the base station;
a gateway control plane (GW-C) device configured to connect to the mobility management entity and the broadcast/multicast service center; and
a gateway user plane (GW-U) device configured to connect to the base station and the broadcast/multicast service center, the GW-C device configured to connect to the GW-U device;
wherein;
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 forwarding indication message for instructing the GW-U device to process a packet received by the GW-U device;
the GW-U device is configured to receive signaling from the base station, and to 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 sent by the GW-U device; and
the GW-U device is further configured to, in a data transmission procedure, receive a broadcast/multicast service data packet from the broadcast/multicast service center and send the broadcast/multicast service data packet to the base station according to the forwarding indication message.

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.
