Abstract
A telecommunications system and method for routing a phone call when the switch serving the caller cannot access a database is disclosed. The system includes a switch serving mobile stations, a node for receiving information from the switch and for determining whether or not the telephone call terminates at a mobile station, a database for sending information when the telephone call terminates at a mobile station and a second database for sending information when the telephone call does not terminate at a mobile station. The method involves receiving the telephone call at a switch serving mobile stations sending information pertaining to the telephone call to a node, determining whether the telephone call terminates at a mobile station, when the telephone call does terminate at a mobile station, accessing one database, and when the call does not terminate at a mobile station, accessing a second database.
