Abstract: In at least one embodiment, an Unlicensed Mobile Access (UMA) network controller for a UMA mobile network is provided. The UMA network controller includes 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. The UMA network controller forwards 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. The UMA network controller further forwards messages relative to a user plan for the circuit switched core network between mobile stations and the media gateway. The UMA network controller further forwards messages relative to a user plan for the packet switched core network between mobile stations and at least one packet switched part.

Abstract: An UMA network controller (SGW,D1,D2) is dedicated for an UMA mobile network comprising a CS core network (CN2) with an MSC and a MGW, a PS core network (CN1) with a SGSN. This UMA network controller comprises a) a security gateway (SGW), a PS part (D1) and a CS part (D2). The security gateway (SGW) is coupled to the MGW, to at least one PS part (D1) and to at least one CS part (D2), and arranged to ensure security procedures between mobile stations (MS) and the UMA world, and to forward messages relative to the control plan for both CS (CN2) and PS (CN1) core networks, and messages relative to the user plan for both the CS (CN2) and PS (CN1) core networks. The PS part (D1) is intercalated between the SGSN(s) and the SGW, and arranged for forwarding user data between the SGSN and mobile stations (MS) through the SGW, and for handling the control plan for the PS core network (CN1) through packet switched call messages over TCP.
