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.

Abstract: The call forwarding is provided within and between telephone networks by establishing a generalized procedure for call delivery and call forwarding. Network protocols are addressed using a common framework for processing call delivery and call forwarding among any combination of different types of networks. An “integrated location management” component realizes the generalized procedure. The integrated location management component is a device capable of holding location information for diverse cellular networks, including Internet telephony systems. The inventive system and method executes generalized call delivery and call forwarding for calls among different types of telephone networks, including wireless networks and Internet networks. The calls may originate from any type of telephony network. Having been initially directed to any of these networks, calls can then be call forwarded to any of these networks.
