Abstract
The present application describes methods for performing proxy communications between mobile stations connected to a femtocell network and a central telephone network controlled by a network operator. In some embodiments, a private branch exchange is configured to temporarily assign identification numbers to the mobile stations connected to the femtocell network. Incoming calls are directed to the private branch exchange rather than the connected mobile stations. After receiving the incoming call, the private branch exchange routes the incoming call to the correct mobile station. In some embodiments, these methods also enable mobile stations to cross between femtocell coverage areas within the same femtocell network without constantly updating the central network operator.
