  • Patent number: 9479543
    Abstract: A method of establishing a communication link between a mobile terminal of a wireless network and a subscriber of a network, such as an enterprise network, and/or a residential network.
    Type: Grant
    Filed: July 10, 2013
    Date of Patent: October 25, 2016
    Assignee: TANGO NETWORKS, INC.
    Inventors: Andrew Silver, Lathan Lewis, Patricia Landgren
  • Publication number: 20160309382
    Abstract: A system, method and computer-readable medium for concurrent support of Voice Call Continuity (VCC) capabilities in both the enterprise space and the carrier space are provided. The enterprise VCC functionality is used when the user is located in the enterprise domain which does not impact the carrier's network while the carrier VCC capability is used when the user is located in the carrier domain to support seamless handover between the wireless networks that the carrier may offer. The carrier VCC anchoring point and the enterprise VCC anchoring point may communicate with each other to confirm and inform the other anchoring point that a call handover is occurring or will occur.

  • Patent number: 9473540
    Abstract: A method of operating a network server, such as a mobile application gateway, connect devices on a cellular or carrier network with individual networks, such as enterprise voice and data networks or residential networks. The effects of the present invention are far reaching in terms of transferring effective call control from the cellular network into the control of the individual network, such as the enterprise, and enabling new business models for the purchase of cellular service from a public cellular carrier by an enterprise.

  • Publication number: 20160212777
    Abstract: A method and apparatus of routing a call in a femtocell network are disclosed. In one example call routing method, a call is originated from the mobile station via a femtocell access point and the call is transmitted to a femtocell gateway, a mobile switching center and a carrier gateway server and onto an enterprise gateway server to obtain policy information. A routing policy is determined based on the obtained policy information and the call is routed to its destination based on the routing policy. The call may be routed via local media from a femtocell access point directly to the enterprise gateway server. The call routing procedures may implement the Iuh protocol and/or the session initiation protocol (SIP) for call signaling in the femtocell network. Call routing may be performed in a wireless cellular communications network or an enterprise network environment.

  • Publication number: 20160156995
    Abstract: A system, method and computer-readable medium for simulating intelligent network triggers in a network system are provided. A mobile terminal is configured with an intelligent network Simulator adapted to detect call events and originate simulated intelligent network triggers in response to the call events. Call progressions implemented according to the simulated intelligent network triggers may be managed or coordinated by at least one of a carrier-gateway server and an Enterprise-gateway server. Call progressions implemented by simulated intelligent network triggers may be specified according to Enterprise member policies or general Enterprise behaviors.

  • Publication number: 20160112462
    Abstract: A mobile application gateway for connecting devices on a cellular network with individual networks, such as enterprise voice and data networks and/or residential networks. The effects of the present invention are far reaching in terms of transferring effective call control from the cellular network into the control of the individual network such as the enterprise, and enabling new business models for the purchase of cellular service from a public cellular carrier by an enterprise. The invention may consist of a primarily of core network and services components based on the IMS network architecture, and is backward compatible to support legacy systems in place in current telecom and data networks.

  • Publication number: 20150131489
    Abstract: A system, method and computer-readable medium for allowing the use of an alternative numbering plan for delivering short messages to mobile subscribers using the public mobile telephone network is provided. Users of an enterprise or other closed networks as well as users that are not part of a closed network may send short messages destined to members of an enterprise or closed network from their mobile or other devices associated with their subscription using an alternative enterprise directory number, such as the office number, instead of the mobile number, such that the alternative number will be presented at the destination device as the originating number. The recipient may respond to the message by addressing the response to the enterprise or closed network number, and the response may be delivered to the originator's mobile or other device associated with their subscription.
