Patent ID: 8306017

Claim:
An Unlicensed Mobile Access (UMA) network controller for an UMA mobile communication network comprising: a circuit switched core network with at least one mobile switching center and a media gateway; and a packet switched core network with at least one serving GPRS serving node, including a security gateway, a packet switched part and a circuit switched part, the security gateway coupled to the media gateway, to at least one packet switched part and to at least one circuit switched part, and arranged to ensure security procedures between mobile stations and an UMA world, to forward messages relative to a control plan for both the circuit switched core network and the packet switched core network between mobile stations and at least one circuit switched part, to forward messages relative to a user plan for the circuit switched core network between mobile stations and the media gateway, and to forward messages relative to a user plan for the packet switched core network between mobile stations and at least one packet switched part, the at least one packet switched part intercalated between the serving GPRS serving node and the security gateway, and arranged to forward user data between the serving GPRS serving node and mobile stations through the security gateway, and to handle the control plan for the packet switched core network through packet switched call messages over TCP, and the at least one circuit switched part being intercalated between the security gateway and a mobile switching center, and arranged to handle the control plan for the circuit switched core network and discovery and registration procedures of the mobile stations, to forward packet switched call messages over TCP between the at least one packet switched part and the mobile stations through the security gateway, and to relay circuit switched call messages between the mobile switching center and the mobile stations through the security gateway.
