SYSTEM AND METHOD OF SELECTING GGSN IN A MOBILE COMMUNICATIONS NETWORK

摘要

A method and system of determining a GGSN to serve data calls in a mobile communications network is provided. Messages are received from a SGSN (310), and analyzed to determine if the message is requesting the identity of a GGSN (315). If the received message is requesting the identity of a GGSN (315), a GGSN selection algorithm is executed to identify a GGSN to serve data calls from a specified MS (325). A reply is then constructed and sent to the SGSN identifying the selected GGSN (330).
