Method and system for enabling communication in a hybrid network

A system capable of initiating a connection between a device of a first party and a device of a second party, the device of the first party configured to initiate the connection by using an addressing scheme usable in a non-Internet-Protocol (IP) based network, the device of the second party is an IP-based device operable in a hybrid network combining a non-IP-based network and an IP-based network, the system comprising:

• (a) a non-IP based network connection module configured to obtain a connection request whose destination is the device of the second party, wherein the non-IP based network connection module is configured to obtain the connection request using only a non-Internet-protocol based signaling;
• and
• (b) an IP-based network connection module configured to provide a route to a Call Session Control Function (CSCF) configured to serve the IP- based network and enable terminating the connection request at the device of the second party;
• wherein the non-IP-based network connection module comprises a registry configured to serve the non-IP based network and does not comprising at least one interface supporting the IP-based signaling;
• and a hybrid Visitor Location Register (VLR) operatively connected to the registry and configured to perform, in cooperation with the registry, authentication and location registration of the IP device of the second party;
• wherein the hybrid VLR is further configured to provide the IP-based network connection module, responsive to a request by the registry issued in response to the connection request, a routing information associated with the IP-based device of the second party, and
• wherein the IP-based network connection module is configured to provide the route to the CSCF using the routing information received from the hybrid VLR.
