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.

Claims (10)

1. A method for transmitting Internet Protocol packets in a wireless transmission system supporting broadcast transmissions, the method comprising:
generating a first transmission frame;
transmitting the first transmission frame with an inner header identifying the source and destination of the first transmission frame;
applying an outer header to the first transmission frame and inner header, the outer header identifying a multicast group destination for the first transmission frame.
2. The method as in claim 1, wherein generating a first transmission frame further comprises:
compressing the inner header.
3. The method as in claim 1, further comprising:
Multicast routing the first transmission frame to multiple target recipients.
4. The method as in claim 3, wherein the first transmission frame is part of a broadcast stream of information, and wherein the multiple target recipients are subscribers to the broadcast stream of information.
5. A method for processing Internet Protocol packets in a wireless transmission system supporting broadcast transmissions, the method comprising:
receiving a first transmission frame having an inner header identifying the source and destination of the first transmission frame;
applying an outer header to the first transmission frame and inner header, the outer header identifying a multicast group destination for the first transmission frame; and transmitting the first transmission frame with the outer header and inner header to the multicast group.
6. The method as in claim 5, wherein the first transmission frame is part of a broadcast stream of information, and wherein the multicast group comprises subscribers to the broadcast stream of information.
7. The method as in claim 6, wherein the first transmission frame is part of a broadcast stream of information, and wherein the multiple target recipients are subscribers to the broadcast stream of information.
8. An infrastructure element for processing Internet Protocol packets in a wireless transmission system supporting broadcast transmissions, the infrastructure element comprising:
means for receiving a first transmission frame having an inner header identifying the source and destination of the first transmission frame;
means for applying an outer header to the first transmission frame and inner header, the outer header identifying a multicast group destination for the first transmission frame; and means for transmitting the first transmission frame with the outer header and inner header to the multicast group.
9. A digital signal storage device, comprising:
first set of instructions for receiving a first transmission frame having an inner header identifying the source and destination of the first transmission frame;
second set of instructions for applying an outer header to the first transmission frame and inner header, the outer header identifying a multicast group destination for the first transmission frame; and third set of instructions for transmitting the first transmission frame with the outer header and inner header to the multicast group.
10. In a wireless communication system supporting a broadcast service, a communication signal transmitted via a carrier wave, the communication signal having a plurality of transmission frames, each of the plurality of transmission frames comprising:

a payload of broadcast content;
an inner header identifying a source and a destination of the payload;
and an outer header identifying a multicast group destination for the payload.
