Abstract:
1. A private base station comprising: a processing unit coupled to a transceiver, the transceiver configured to intercept messages between a wireless communication terminal (UE) and a circuit switched (CS) network; the processing unit configured to create a security context for the UE when the UE is successfully authenticated by the CS network and to configure the transceiver to intercept further messages using the security context; the processing unit configured to create an IP Multimedia Subsystem (IMS) identity for the UE if the UE is authenticated by the CS network, and the processing unit configured to register the UE with an IMS network using the IMS identity; the processing unit configured to cause the transceiver to establish a signaling connection with the CS network when the UE sends a service request for the CS network; the processing unit configured to cause the transceiver to send an IMS session request to the IMS network and to not forward a service request by the UE to the CS network when the IMS network can accommodate the service request, wherein the IMS session request corresponds to the service request; and the processing unit configured to cause the transceiver to release the signaling connection with the CS network after the session request is sent to the IMS network.
