  • Patent number: 7869791
    Abstract: A secondary Ethernet-like wireless communication system overlapped by a dominant Ethernet-like wireless communication system, and including radio access and communication for activation, association, and authentication of a wireless device in the secondary Ethernet-like wireless communication system. An automated private service activation (APSA) port is used for accepting access and communication requests of a wireless device seeking activation, association and authentication in the secondary Ethernet-like wireless communication system. The APSA port provides an access and communication channel for radiating signals at a level exceeding a signal level of the access and communication channel only within limited spatial constraints. In addition the APSA port provides space for receiving the wireless device for activation and communication in the secondary Ethernet-like wireless communication system.

  • Patent number: 7720102
    Abstract: The present invention sets forth a network-centric service distribution method that integrates a wireless access system/service in the residence, SOHO, business or public environment through the use of a local broadband network, such as a Residential-Business Broadband Network (RBN), to the service provider's broadband transport network and to a service provider's broadband packet network that facilitates end-to-end packet telecommunication services. The method includes the step of connecting said service provider's broadband packet network to the RBN via said service provider's broadband transport network. Call and service termination functions to a plurality of local RBN devices are also provided in the method. Signals from a plurality of wireless devices are accepted and forwarded to an IEEE 802.11b interface for a wireless modem and/or to an Ethernet interface for a Voice over Internet Protocol (VOIP)/Ethernet Processor, where the forwarded signals comprise intranet telephony and data.

  • Patent number: 7103347
    Abstract: Automatic activation of a wireless device with a first wireless communication system occurs within an area having an overlapping second wireless communication system. Operation of the first communication system access procedure is achieved by masking an access and authentication process for the second communication system from interference from the control signal levels of the second wireless communication system. During the first time access, the first communication system is supplied with the SID and MIN and ESN numbers for authentication and access.

  • Patent number: 7002995
    Abstract: The present invention sets forth a network-centric service distribution architecture that integrates a wireless access system in the residence, SOHO, business or public environment through the use of a local broadband network, such as a Residential-Business Broadband Network (RBN), to the service provider's broadband transport network and to a service provider's broadband packet network. The system includes a Media Terminal Adapter coupled via the RBN to the access port(s) and via the service provider's broadband transport network to the service provider's broadband packet network. The access port is coupled to the Media Terminal Adapter via either an RBN (e.g., a Local Area Network—LAN) or simply via a traditional POTS line interface. The access port receives and sends wireless signals to a plurality of RBN devices, allowing the user to control these devices remotely from the residence, business, SOHO or public environments.

  • Patent number: 6975634
    Abstract: Integration of packet/cell networking of a wired/wireless network with ATM is achieved by application of a distributed architecture including an ATM network adapted to provide such integration. Network and protocol conversion between the wired/wireless network and the ATM network is performed by a gateway (GAGW) having capabilities to perform this function. A mobility server platform (MSP) handles routing between the gateways to other networks and the micro-mobility functions of the wireless base stations directly connected to the ATM network. A Inter-working function (IWF) element connects base stations (BS) or mobile switching centers (MSC) to ATM switch/routers and in the process provides various protocol conversions necessary to integrate various services into the ATM backbone. The integration of these networks is seamless with little apparent affect on the end point users of the ATM network on the overall system.

  • Patent number: 6643504
    Abstract: Automatic activation (i.e., first time access) of digital wireless/cellular mobile telephones with a private/localized wireless/cellular system (i.e. a secondary system) occurs within an area having an overlapping macrocellular primary wireless communication system (i.e., a dominant system). Operation of the secondary access procedure is achieved by shielding/masking an access and authentication process for the secondary system from interference from the control signal levels of the dominant wireless communication system. During the first time access, the secondary system is supplied with the SID and MIN and ESN numbers for authentication and resultant access.
