ABSTRACT:
A system and method is provided for transmitting a packet received at a Foreign Agent associated with a Packet Data Service Node where the packet has a source network layer address, such as an Internet Protocol address of a mobile station that points to a geographically remote Home Agent and a destination Internet Protocol address. The method comprises caching Internet Protocol addresses in memory, comparing the destination Internet Protocol address of the received packet with the Internet Protocol addresses in memory, and if no match is found, querying a Policy Server for a match, and forwarding the received packet with the Internet Protocol address of the Foreign Agent associated with the Packet Data Service Node as the source Internet Protocol address when the destination address of the received packet matches the Internet Protocol address in memory or Policy Server, resulting in significant savings in transport cost and response time.
