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.

Apparatus and method for enabling optimized gateway selection for inter-working between circuit-switched and internet telephony

A Global Roaming Application Server is adapted to act as an intermediary between all Internet Protocol (IP)-based network(s) and non-IP-based network(s), such as a circuit-switched landline network, an ANSI-41 network, wireless LAN network, a Global System for Mobile Communications network or Universal Mobile Telecommunications System network. In a first or forward direction, the Application Server enables a user in a non-IP network to be located in accordance with user profiles at the request of another user who has chosen to send a message via an all-IP based network. After the user in the non-IP network is so located, the Application Server enables a signaling link to be created between the two users. The Application Server may also be used to enable a signaling link when a message is sent in a second, or reverse direction.

Methods and devices for providing seamless global roaming using an all-IP network

The inventors provide herein methods for the decomposition of initial Filter Criteria (iFCs) into user-independent, global data and user specific data. In various embodiments of the present invention, the approach is based on Trigger point templates that represent families of trigger points, which are able to be instantiated to real trigger points by adding missing user specific data. Trigger point templates are specified at service deployment time and are instantiated to real trigger points and complemented with the other iFC components to form complete iFCs at the time of service subscription. It is demonstrated that the trigger point methods of the present invention facilitate the storing, provisioning and downloading of initial filter criteria and are beneficial in terms of at least storage and run-time efficiency.

Method for deploying, provisioning and storing initial filter criteria

Signaling paths and communication sessions, such as voice-over-IP sessions, can be established in substantially shorter and predictable time periods than previously thought possible over carrier-based, peer-to-peer networks (P2P). Instead of requiring a signaling pathway to traverse a large number of hops/nodes, novel architectures permit a signaling pathway to traverse a few designated host and anchor nodes that are part of a core of a P2P network. The novel architectures and related methods also make it possible to easily manage and maintain P2P networks.

Methods, devices and architectures for establishing peer-to-peer sessions

A method and a system for providing a connection to a subscriber having multiple subscriber devices utilizing different communications protocols are disclosed. The subscriber is associated with an address to which incoming calls are addressed. The method and system provide for completing an incoming call to the subscriber address via one of the subscriber devices, where the device is selected from the subscriber devices based on a subscriber profile. The profile generally includes respective service profiles for each of the communications protocols utilized to establish the call, respective service profiles for each of the subscriber devices, and a user destination selection policy describing routing parameters that determine routing of the call to one or more of the subscriber devices.

Method and apparatus for routing telephone calls across different types of networks includes means for and steps of determining a destination IP address of a new call according to initial conditions established in a first network, determining a destination gateway (gateway brokering) based on the destination IP address, the initial conditions and a gateway selection policy, providing routing information of the destination gateway to the first network and completing the new call set up via messages received from the gateway brokering step. The initial conditions in the first network are established by determining if a callee is part of an IP network or part of a CS network and converting the callee phone number to an SIP URL if the callee is part of the IP network. Such determination is made by recognizing a prefix identifying an IP destination in the callee phone number.

Method and apparatus for call routing via gateway brokering

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.
