METHODS AND SYSTEMS FOR COMMUNICATING BETWEEN SUBSCRIBERS OF DIFFERENT APPLICATION-LAYER MOBILE COMMUNICATIONS PROTOCOLS

摘要

A routing node (102) communicates between subscribers of different application-layer mobile communications protocols, such as IS-41 and GSM, without converting each IS-41 message to GSM and vice versa. Rather than converting each message to the protocol of the intended recipient, the routing node (102) functions as an HLR to provide the location of a mobile subscriber in a different application-layer mobile communications protocol and as an MSC to forward short message service messages to a short message service center (11) of the other application-layer mobile communications protocol.
