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.

A mobile application gateway configured to interconnect mobile communication devices on a cellular network with an enterprise network is provided. The mobile application gateway includes a voice and data signaling gateway configured to provide routing functionalities, service functionalities and admission control. A gateway GPRS support node (GGSN) is configured to establish a secure data session between one or more of the mobile communication devices and the enterprise network by establishing a GPRS tunneling protocol (GTP) tunnel between a carrier-hosted serving GPRS support node (SGSN) and the GGSN.

In a call forwarding system, a management apparatus of the call forwarding system determines service terminals capable of near field wireless communication within a reception range of near field wireless communication, generates a terminal list, and receives a call event message reporting the receipt of a call from a reference terminal. The management apparatus may transmit a call report message including the terminal list to the reference terminal and the service terminals. The management apparatus may forward the call initially received by the reference terminal to a terminal which transmitted a receipt request message by transmitting a call forwarding request message to the reference terminal. The management apparatus may transmit, to the reference terminal and the service terminals, a receipt report message reporting the call was forwarded. According to a change receipt message or upon non-receipt by an intended terminal, the call may be reforwarded to another terminal.

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.

A system, server, and method of DTMF detection in a VoIP network.

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.

A mobile device determines whether the mobile device is docked with a docking station that connects to a VoIP network, where the mobile device is capable of receiving calls to a cellular telephone number and calls to a VoIP telephone number. The mobile device notifies, if the mobile device is docked with the docking station, a call handling node in a cellular network to forward calls destined for the cellular telephone number to the VoIP telephone number at a VoIP call server. The mobile device receives a call forwarded from the VoIP call server, where the call was originally destined for the cellular telephone number.

A gateway 202 identifies mobile devices 210 connected to it. Communication access numbers associated with the mobile devices are then obtained and synchronized with communication access numbers associated with the gateway. The gateway notifies a service provider for the mobile device that its calls should now be routed to the gateway instead of the mobile device. Calls received by the gateway can then be delayed, reformatted and/or otherwise transformed/controlled by the gateway and passed to connected landline devices.
