The present invention provides a method for transmitting broadcast programs, broadband wireless multimedia network, including: radio data from the broadcast content server through IP unicast transmission to broadcast and access network gateway; the broadcast data from the radio access network and network transmission to the user terminal by closing multicast. In addition, the invention also provides a kind of broadband wireless multimedia network and a radio access network gateway, data transmission using IP unicast and multicast network special way of combination, reduces the cost of network construction. At the same time, the broadcast program data and the program control commands can be transmitted through different channels to avoid the complex frame structure and protocol needed on the downlink channel of the broadcast program to transmit additional program information. Thus the design of the system is simplified.
