Abstract
A femtocell authentication system includes a femtocell in communication with an Internet protocol multimedia subsystem (IMS) network. The IMS network includes a gateway and a first server. The femtocell includes a global positioning system (GPS) module to obtain geolocation information of the femtocell and transmit the geolocation information to the first server. The first server includes a storage unit and a signal processing unit, the signal processing unit compares the geolocation information with a predetermined geolocation range value in the storage unit and allows the femtocell access to the IMS network according to a determination by the signal processing unit that the femtocell is within the predetermined geolocation range of the IMS network.
