Abstract
Method and apparatus for data packet transport in a wireless transmission system supporting broadcast transmissions. Broadcast streams are provided in IP packets routed to a subscriber group. The PDSN applies an outer header to each broadcast stream frame identifying the frame as part of a multi-cast transmission. The PDSN transmits the frames to at least on PCF, wherein the PCF duplicates the received frame for each user in the subscription group, alleviating the processing of the PDSN.
