METHOD AND SYSTEM FOR IMPLEMENTING MULTICASTING SERVICE OR BROADCASTING SERVICE BASED ON THE NEXT GENERATION NETWORK

摘要

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.
