Abstract
Some embodiments are implemented in a communication system that includes a first wireless communication system that includes a Femtocell access point (FAP) and a network controller that can communicatively couple the FAP to a second wireless communication system. In some embodiments, the network controller can communicatively couple to the second 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 method that determines whether a user equipment (UE) has roved-out of the first wireless communication system. The method receives a periodic message at the FAP from the UE. When the FAP fails to receive a pre-determined number of the periodic messages, the method sends a deregister message to the network controller over a unique connection dedicated to the UE and releases the dedicated connection.
