Abstract:
1. A method of initiating a connection between a device of a first party and a device of a second party, the device of the first party initiates the connection by using an addressing scheme usable in a non-Internet-Protocol based network, the device of the second party is an Internet-Protocol (IP)-based device operating in a hybrid network combining a non-IP based network and an IP based network, the method comprising: (a) obtaining by a registry serving the non-IP based network a connection request addressed to the IP-based device of the second party as a destination, wherein the connection request uses a non-IP based signaling and is obtained by the registry without involvement of an IP-based signaling, and wherein the registry does not comprise at least one interface supporting the IP-based signaling; (b) requesting a hybrid Visitor Location Register (VLR) to provide a routing information associated with the device of the second party, wherein the hybrid VLR is configured to perform, in cooperation with the registry, authentication and location registration of the IP-based device of the second party; and (c) providing a route to a Call Session Control Function (CSCF) configured to serve the IP- based network, thereby terminating the connection request at the device of the second party, wherein the route is provided using the routing information received from the hybrid VLR.
