Abstract: The present invention provides an apparatus, system and method for providing location register routing in a mobile telecommunication network. A mobile switching center enabled IS-41 query message requesting information related to a specific mobile unit is routed to a signaling transfer point with location register routing capabilities for routing to a remote database containing the requested information. The signaling transfer point validates the query message for location register routing and forwards the query message for processing to a location register routing application where a mobile identification number or a mobile directory number is extracted from the query message. The application uses the mobile identification number or mobile directory number to perform an address translation in a network address database which contains the remote database network address. The translated remote database network address is subsequently incorporated in the query message for network routing to the remote database.
