1. A method of determining a GGSN to serve data calls in a mobile communications network having at least two GGSN'"'"'s and a SGSN in a network, comprising the acts of:
- receiving messages from a SGSN;
analyzing the received message to determine if it is requesting the identity of a GGSN;
if the received message is requesting the identity of a GGSN, executing a GGSN selection algorithm to identify a GGSN to serve data calls from a specified MS;
constructing and sending a reply to the SGSN identifying the selected GGSN.

Abstract
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, and analyzed to determine if the message is requesting the identity of a GGSN. If the received message is requesting the identity of a GGSN, a GGSN selection algorithm is executed to identify a GGSN to serve data calls from a specified MS. A reply is then constructed and sent to the SGSN identifying the selected GGSN.

5. A system for determining a GGSN to serve data calls in a mobile communications network having at least two GGSNs and a SGSN in a network, comprising:
-
IP packet reception logic to receive messages from a SGSN;
IP packet analysis logic to determine if the received message is requesting the identity of a GGSN;
GGSN selection logic, responsive to the IP packet analysis logic, to identify a GGSN to serve data calls from a specified MS;
IP packet reply logic to construct and send a reply packet to the SGSN identifying the selected GGSN. - View Dependent Claims (6, 7, 8)
