Title: METHOD FOR IMPLEMENTING MULTICAST SERVICE OF PACKET TRANSMISSION NETWORK, DEVICE THEREOF AND COMMUNICATION SYSTEM
Abstract:
A method for implementing a multicast service of a packet transmission network, a device thereof and a communication system. A packet transmission network device receives a multicast service transmitted by a gateway device by means of a point-to-multipoint (P2MP) channel, and the packet transmission network device pushes the multicast service to a downlink base station.
