  • Patent number: 8064907
    Abstract: Some embodiments provide a method of associating Mobile Management Entities (MMEs) of an evolved packet system (EPS) and Voice over long term evolution (LTE) via Generic Access (VoLGA) network controllers (VANCs). The method includes at a serving VANC, receiving a registration message from a user equipment (UE). The registration message includes an assigned Globally Unique Temporary Identity (GUTI) of the UE and the serving VANC is provisioned with MME-to-VANC mapping information. The method extracts an identification of a MME from the GUTI and determines an associated VANC based on the provisioned MME-to-VANC mapping information. The method then sends a message from the serving VANC to the associated VANC, the message indicating that the serving VANC is now serving the UE.

  • Patent number: 8041335
    Abstract: Some embodiments are implemented in a communication system that includes a first communication system comprised of a licensed wireless radio access network and a core network, and a second communication system comprising a plurality of user hosted access points and a network controller. In some embodiments, each access point operates using short range licensed wireless frequencies to establish a service region. In some embodiments, the network controller communicatively couples the core network to the plurality of access points. The method enables an unauthorized user equipment to call from an access point it is not allowed to use for emergency purposes. The method receives at an access point a service request from an unauthorized user equipment with an establishment cause of emergency call. The method sends a registration request to the network controller. The method sends a message to the core network indicating the location of the user equipment.

  • Patent number: 8019331
    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.

  • Patent number: 8005076
    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.

  • Patent number: 7995994
    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.
