Patent ID: 8233417

Claim:
A femtocell comprising: a transceiver that receives a first request signal from a first service request device (SRD) that operates in at least one of a circuit switched (CS) domain and a packet switched (PS) domain; and a control module that generates a second request signal based on the first request signal, wherein the transceiver transmits the second request signal in at least one of the CS domain and the PS domain from the femtocell to a mobile switch center (MSC) server, the transceiver provides Internet protocol multimedia subsystem (IMS) centralized services (ICS) to the first SRD based on the second request signal, the transceiver receives the first request signal in the CS domain and transmits the second request signal in the CS domain, the transceiver receives a third request signal from a second SRD, the control module generates a fourth request signal based on the third request signal, the transceiver transmits the fourth request signal in a packet switched domain to a service centralization and continuity application server (SCC AS), and the transceiver provides the ICS to the second SRD based on the fourth request signal.
