Abstract
Systems and methods for recovering and managing location information in mobile communication networks using a fast recovery protocol and load balanced query and update processes. According to the fast recovery protocol, if a location update processor does not receive a message from a global database server acknowledging receipt by the global database server of a location update message after a predetermined retry interval has elapsed since the location update message was sent by the location update processor, the location update processor sends a location update retry message after each predetermined retry interval elapses until the location update processor receives an acknowledgement message from the global database server. The global database server can use the location update retry messages and the predetermined retry interval to recover from a database or link failure. The recovery period using the fast recovery protocol is bounded by the predetermined retry interval. The fast recovery protocol can also be used in a system having a distributed location information database architecture. The load balanced query and update processes can be used to query and update, respectively,…
