Method and apparatus for selecting a packet data serving node for multi-cast/broadcast services
First Claim
1. In a wireless communication system supporting broadcast transmissions, the system having a protocol control function node and a plurality of packet data service nodes, a method for setting up transmission paths comprising:
- determining a first number of the plurality of packet data service nodes communicable with the protocol control function node; and
determining a first packet data service node for a first communication as a function of the first number, wherein the determined first packet data service node supports the transmission paths for all mobile stations which are to receive a first broadcast transmission through the protocol control function node.

Abstract
Method and apparatus for selecting a Packet Data Service Node (PDSN) for a communication in a wireless transmission system supporting broadcast transmissions. The packet control function node determines a number of communicable PDSNs and assigns each a unique identifier. The PCF then selects one of the communicable PDSNs based on the multi-cast address of a given communication. One embodiment performs a modulo operation on a function of the multi-cast address and the number of communicable PDSNs, wherein the result of the modulo operation corresponds to a unique identifier.
