Method and apparatus for preventing theft of service in a communication system

A computer readable medium storing a computer program for execution, the computer program for preventing theft of service in a communication system comprising a first wireless communication system and a second wireless communication system comprising a Femtocell access point (FAP) and a network controller communicatively coupling the FAP to the first wireless communication, the computer program comprising sets of instructions for:

• a) creating an authorized session comprising a session identity for a first user equipment (UE), said session for communicatively coupling the first UE with the first wireless communication system through the FAP, the first UE recognized by the first wireless communication system as an authorized UE to use the FAP, the first UE identified by a set of identities;
• and
• b) rejecting a request by the FAP to register a second UE when an identity of the second UE does not match any identity in said set of first UE identities, wherein the rejected request comprises the session identity of the authorized session and the identity of the second UE, the second UE not recognized by the first wireless communication system as an authorized UE to use the FAP.
