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.

The present disclosure discloses a system and a method for automatic call synchronization. When a mobile terminal receives a called signal from a calling mobile terminal and determines that an automatic call synchronization function is enabled by itself, the mobile terminal transmits, to a wireless signal transponder, a call synchronization request which carries identification information and call information of the mobile terminal; a mode recognition unit which is connected to the wireless signal transponder performs an authentication on the mobile terminal according to the identification information of the mobile terminal; and transmits a call access request which carries the identification information and the call information of the mobile terminal to the fixed terminal via the wireless signal transponder, after the authentication on the mobile terminal is passed.

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.

The present disclosure relates to a system for initiating a call from a landline that is mapped to a caller mobile phone, wherein system includes a call request receipt module configured to, at a first computing device, receive, from the caller mobile phone, a call request comprising a caller identifier and a callee phone number; a landline determination module configured to, at the first computing device, determine the landline based on the received caller identifier, a landline based call initiation module configured to, using the first computing device, initiate a first call to landline number of the determined landline; a callee call initiation module configured to, using the first computing device, initiate a second call to callee phone number; and a callee connection module configured to conference the first call with the second call.

Embodiments of the present invention include a Voice Virtual Private Network (Voice VPN) and methods for providing access to remote peer users across same. In one embodiment, voice and communication services of one or more corporate network are provided to remote user terminals across a Voice VPN Gateway. The level and type of access to voice and communication services provided can be determined statically, dynamically, or adaptively based on user data or user habits or history.

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.
