<p>An UMA network controller (SGW, CM) is dedicated for an UMA mobile network comprising a CS core network (CN2) and a PS core network (CN1) with a SGSN. This UMA network controller comprises a security gateway (SGW) and a control means (CM) coupled one to the other. The security gateway (SGW) is arranged i) to ensure security procedures between mobile stations (MS) and the UMA world, ii) to forward messages relative to the control plan for the packet switched core network (CN1) between mobile stations (MS) and the control means (CM), and iii) to forward messages relative to the user plan for the packet switched core network (CN1) between mobile stations (MS) and the serving GPRS serving node (SGSN). The control means (CM) is intercalated between the security gateway (SGW) and the serving GPRS serving node (SGSN) and arranged for handling the control plan for the packet switched core network (CN1).</p> |
