Abstract
The present invention provides a method and apparatus for controlling the transmission of uplink multicast service data in communication network. According to the invention, a user equipment sends request to a multicast controlling device for the permission of providing uplink multicast data stream; once the uplink multicast controlling device has verified and accepted the request, it will assign multicast address, bandwidth, valid time for it and update the uplink multicast forwarding table at the access device to establish an uplink multicast dedicated VLAN. After that, the access device will forward multicast data from the UE according to the uplink multicast forwarding table configured by the uplink multicast controlling device, to be specific, allowed multicast packets to be forwarded into the uplink multicast dedicated VLAN, and get to the multicast router via the uplink multicast dedicated VLAN. Finally, the multicast router will take the responsibility of multicast distributing of the uplink multicast service data. Based on the present invention, the access of uplink multicast and the data transmission can be well controlled, the multicast routers provide multicast service to the network in a centralized manner. Also, this is compatible with the existing multicast and unicast services.
