    Abstract: Method and system for implementing multicasting service and broadcasting service based on the next generation network. When the current core network side does not support IP multicasting method, the method and system may solve the problem of implementing multicasting service or broadcasting service in way of unicasting. When the terminal requires to establish multicasting service or broadcasting service, an application processing module transfers parameters for establishing transmission channel and the multicasting/broadcasting media stream parameters to transmission processing module, and establishes the unicasting transmission channel between the transmission processing module and the media providing device which provides multicasting/broadcasting service. The media providing device unicasts the required multicasting/broadcasting media stream to the transmission processing module through the transmission channel. Then the transmission processing module multicasts the multicasting media stream to the terminal, or broadcasts the broadcasting media stream to the terminal by using IP multicasting technology. It implements the unicasting of multicasting/broadcasting service when the core network side does not support IP multicasting method.

    Abstract: A media stream control method includes :the service control unit sends a request for converting multicast media stream to the multicast media stream conversion unit; after the multicast media stream is received by the multicast media stream conversion unit, the multicast media stream is converted into a unicast media stream or a new multicast media stream and is sent to the service reception party. Still there are a NGN-based media stream control method, a media stream conversion device, a BGF, a multicast system and a NGN-based multicast system. The received multicast media stream may be converted into a unicast media stream or a new multicast media stream, so that it can be ensured that the media stream is successfully transported through the subsequent IP network until it reaches the service reception party. Therefore it can be ensured that the media stream is received normally by the service reception party.

    Abstract: A IMS-based streaming media network system, includes: a streaming media service enable entity, for providing streaming media service description to the user terminal; a application server, for sending the media resource request after the user terminal chooses a streaming media service according to the service description and the application server has received the service request sent by the user terminal, and providing the information of the media resource delivery function entity to the user terminal after the application server has got the information of the media resource delivery function entity which stores the streaming media content; a media server, for providing the information of the media resource delivery function entity to the application server according to the media resource request sent by the application server. A IMS-based streaming media service enable entity and a IMS-based streaming media service realization method are also provided. It resolves the question of realizing the streaming media service over IMS network architecture.
