Apparatus and method for enabling optimized gateway selection for inter-working between circuit-switched and internet telephony
First Claim
1. A method of selecting a gateway for interworking between a first and second network supporting different network protocols, said method comprising the steps of:
- querying a unified location management device having location information stored therein for users of said different network protocols;
relaying mobile user location related information from said unified location manager regarding a user of said one of said first and second network; and
selecting said gateway based on said location information provided.

Abstract
An optimized gateway selection process of the present invention is based on a universal mobility manager (UMM), a component for inter-technology location management. The UMM is capable of holding location information for diverse cellular networks, as well as for Internet telephony systems. For cellular networks, UMM acts as a traditional HLR; for an Internet telephony network, it acts as the entities that are responsible for user/terminal registration (registrar in SIP, gatekeeper in H.323) and address resolution (proxy server in SIP, gatekeeper in H.323). An optimal gateway selection is possible based on location related information provided by the UMM which had not previously been available. Utilizing the newly available information enables a gateway to be selected which may, for example, enable the circuit switched portion of a call to now be minimized.
