A routing node 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 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 of the other application-layer mobile communications protocol.
