Claim:
A method of terminating calls in a network system, comprising: provisioning a femtocell system with a list that specifies at least one electronic serial number of a user equipment authorized to access the femtocell system; receiving a call setup request by the femtocell system from a first user equipment, the call setup comprising a directory number of a second user equipment; determining the directory number of the second user equipment to which the call is directed; interrogating the list with the directory number of the call setup request to determine if a directory number of the list matches the directory number of the second user equipment; performing an evaluation of whether the second user equipment is authorized to access the femtocell system by evaluating whether the directory number is assigned to the second user equipment that is authorized to access the femtocell system, and by evaluating whether the second user equipment is currently operating in a service area of the femtocell system; and completing the call setup based on results of the evaluation.
