Abstract

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.

Claims

1. A system, comprising:

a cellular network including a mobile switching network that provides cellular telecommunication services to cellular phones;

a carrier gateway server that is communicatively coupled with the mobile switching network; and

an enterprise network including an enterprise gateway server that is communicatively coupled with a PBX located in the enterprise network;

wherein the enterprise gateway server is communicatively coupled with the carrier gateway server and wherein signaling information only is transmitted between the carrier gateway server and the enterprise gateway server,

wherein the carrier gateway server receives an indication from the mobile switching network that a call is originating or terminating for a cellular phone associated with the enterprise network,

wherein the carrier gateway server identifies the enterprise network of the associated cellular phone,

wherein the carrier gateway server notifies the enterprise gateway server of the call and call information of the originating or the terminating call,

wherein the enterprise gateway server stores the call information including an originally intended destination,

wherein the enterprise gateway server determines a call routing for the call.

2. The system of claim 1, wherein the enterprise gateway server informs the carrier gateway server of the call routing.

3. The system of claim 2, wherein the carrier gateway server orders the mobile switching network to perform the call routing.
