Abstract: Some embodiments are implemented in a communication system that includes a first wireless communication system and a second wireless communication system that includes a Femtocell access point (FAP) and a network controller that can communicatively couple the FAP to the first wireless communication system. In some embodiments, the network controller can communicatively couple to the first wireless communication system through a UTRAN Iu interface. In some embodiments, the FAP can communicatively couple to a user equipment using a short-range licensed wireless frequency. Some embodiments provide a method that registers a Femtocell access point (FAP). The method sends a register request message that includes a registration type from the FAP to the network controller. The registration type identifies the FAP as a device to be registered with network controller. When the register request message is acceptable by the network controller, the FAP receives a register accept message.
