ABSTRACT:
For use in a telecommunications network comprising a plurality of packet data service nodes and a plurality of mobile stations, wherein each packet data service node is capable of communicating with one or more mobile stations, there is disclosed an apparatus and method for avoiding triangulation delay that is caused by sending messages over a long network path. The apparatus comprises an interface between the packet data service nodes. Information sent over the interface permits a first packet data service node to send data packets of a message from a first mobile station to a second mobile station directly from the first packet data server node to a second packet data server node without accessing an Internet (IP) protocol network. This avoids triangulation delay by decreasing the length of the network path for the message.
