  • Patent number: 8045493
    Abstract: A network controller operates in an unlicensed wireless communication system including a first radio access network. The network controller includes a Up interface for communicating with a mobile station and an IP network interface. The network controller includes a network interface for connecting the network controller to a UMTS core network that is accessible to a second radio access network that includes a UTRAN. The network interface includes an Iu-CS interface to communicate with a MSC in the UMTS core network. The network interface supports signaling protocols for circuit-switched services while inter-working with the UMTS core network via the Iu-CS interface using a layered protocol that includes a RANAP layer over a SCCP layer and several Iu-CS control plane lower layers. The network controller includes modules for generating and/or processing messages transmitted over the network interface. The network controller appears to the UMTS core network as a UTRAN RNC.

  • Patent number: 8036664
    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.

  • 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.

  • Publication number: 20110182243
    Abstract: Techniques for performing messaging between mobile stations (MSs) and UMA network controllers (UNCs) in an unlicensed mobile access network (UMAN). URR (UMA radio resource) messages are exchanged between an MS and one or more UNCs to perform various operations associated with UMAN. The MS may access the UMAN via a wireless access point (AP) that is communicatively coupled to the UNC via an IP network. The URR messages are sent between MSs and UNCs using an Up interface comprising a set of layered protocols over an underlying IP transport.

  • Publication number: 20110044219
    Abstract: Mechanisms to extend UMA (Unlicensed Mobile Access) or GAN (General Access Network) to inter-work with a UMTS (Universal Mobile Telecommunications System) core network. A UMA network controller (UNC) is provided to interface between a UMA network and a UMTS core network using the standard Iu-CS and Iu-PS interfaces. From the viewpoint of the UMTS core network, the UNC appears as another Radio Network Controller (RNC). Protocol layer schemes are disclosed for mobile stations, UNCs, SGSNs and MSCs to support signaling and data messaging in both the packet-switched and connection-switched domains. The mobile stations provide dual-mode operation, such that they are able to access the UMTS core network via unlicensed service when in a UMA access area, and to access the UMTS core network via licensed service when outside of a UMA access area and in a UTRAN service area.
