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. Some embodiments provide a resource management method that determines that a user equipment (UE) has roved in a region serviced by the FAP. The FAP includes a generic access resource control (GA-RC) protocol sub-layer. The method creates a separate GA-RC state dedicated to the UE in the GA-RC protocol sub-layer. The method also sets the GA-RC state dedicated to the UE to a deregistered state to indicate that the UE is not registered to use the services of the second wireless communication system.

Abstract: Some embodiments of the invention provide a communication system that includes a first communication network, a second communication network, and a core network. The second communication network includes a network controller and a group of two or more access areas that are communicatively coupled to the core network by the network controller. Some embodiments service the second network access areas by providing access area identifiers to each access area while communicating with the first network or core network using a single are identifier assigned to the network controller. Some embodiments provide access control by sending a series of invalid messages to a user equipment (UE) that is not authorized to access services of the second network to reject the UE. Some embodiments reject the UE by sending a message to ban a UE from an access area with a particular access area identifier.

Abstract: Some embodiments provide a method of registering a user equipment (UE) in a communication system that includes a licensed wireless communication system and a generic access network (GAN) that has a generic access network controller (GANC). The method sends a register request message from the UE to the GANC that indicates a GAN mode capability of A/Gb only for the UE. When the GANC has a GAN mode capability of A/Gb, the GANC registers the UE with the GAN. When the GANC has a GAN mode capability of Iu only, the GANC rejects the register request message. When the GANC has a GAN mode capability of both A/Gb and Iu, the GANC registers the UE based on a set of GANC mode selection rules that the GANC applies for registering UEs with the GAN.

Abstract: Some embodiments provide a method of identifying a list of Femtocell Access Points (FAPs) for a user equipment (UE) communication session in a communication system including a first wireless communication system and a second wireless communication system. The second wireless communication system includes multiple FAPs and a Femtocell gateway (FGW) that communicatively couples the FAPs to the first wireless communication system. The method receives information about a UE that has detected a particular FAP that has an identification attribute. The method uses the UE information to retrieve a set of FAPs designated for the UE where the FAPs in the set of FAPs have the same identification attribute as the particular FAP. The retrieved set of FAPs is from a set of several FAPs that are not designated for the UE but have a same identification attribute as the particular FAP.

Abstract: A method of preventing theft of service 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. The method creates an authorized session that includes a session identify for a first user equipment (UE). The UE is recognized by the first communication as an authorized UE to use the FAP. The method rejects a request by the FAP to register a second UE when the identity of the second UE does not match any identity in the set of first UE identities. The rejected request includes the session identity of the authorized session and the identity of the second UE. The second UE is not recognized by the first communication system as an authorized UE to use the FAP.
