First Claim
Patent Images
1. In a wireless communication system supporting a broadcast service, a method comprising:
- receiving an IP multicast address and a service option parameter for the broadcast service from a base station during establishment of a user traffic channel between a packet data serving node and a base station;
receiving a broadcast packet flow sent via an IP network;
using the service option parameter to determine header compression;
compressing a packet header of the broadcast packet flow; and
mapping the broadcast packet flow identified by an address in the packet header to the user traffic channel using the IP multicast address.

Abstract
A method and apparatus for flow treatment and flow mapping of a broadcast/multicast service is disclosed. A base station provides flow treatment and mapping data to a packet data serving node during the establishment of a user traffic channel. The flow treatment and mapping data includes an IP multicast address and a service option parameter. A content server sends a broadcast packet flow to the packet data serving node via an IP network. Header compression for the packet flow is determined from the service option parameter. The packet flow is mapped to the appropriate user traffic channel using the IP multicast address.

21. A packet data serving node for receiving IP packets from an IP network and operating to send the IP packets to a base station, the packet data serving node comprising:
-
an A10 connection for communicating user traffic to the base station;
an A11 connection for communicating signaling information to the base station;
an IP network connection for connecting the packet data serving node to the IP network;
flow treatment and mapping data comprising an IP multicast address and a service option parameter, wherein the packet data serving node is configured to receive the flow treatment and mapping data from the base station over the A11 connection in establishing the A10 connection and wherein the packet data serving node is further configured to store the flow treatment and mapping data;
means for mapping the IP packets to the A10 connection based on a multicast address of the IP packets and using the flow treatment and mapping data; and
means for compressing an IP header based on the service option parameter. - View Dependent Claims (22, 23, 24, 25, 26)
