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.

Claims

1. A method, comprising:

coupling an enterprise gateway server in an enterprise network with a carrier gateway server in a carrier network; and

establishing a secure tunnel between the enterprise gateway server and the carrier gateway server, wherein the secure tunnel supports selectable security and encryption specific to requirements of the enterprise network.

2. The method of claim 1, comprising identifying, by the carrier gateway server, the enterprise network, wherein identifying the enterprise network comprises identifying at least one of:

the enterprise network based on calling party information of a call;

the enterprise network by information in at least one of an originating trigger or a terminating trigger; and

the enterprise network based on subscription information maintained by the carrier network.

3. The method of claim 2, wherein the subscription information is obtained from one of a home subscriber server and a home location register.

4. The method of claim 1, comprising coupling the enterprise gateway server with a private branch exchange deployed in the enterprise network.

5. The method of claim 1, comprising;

notifying, by the carrier gateway server, the enterprise gateway server of the call;

determining, by the enterprise gateway server, a call routing for the call, wherein communicating with the enterprise gateway server to obtain the call routing comprises performing a signaling exchange between the carrier gateway server and the enterprise gateway server.

6. The method of claim 1, comprising configuring the enterprise gateway server as an endpoint of the enterprise network.

7. The method of claim 1, comprising:

receiving, by the carrier gateway server, an indication that a call is originating or terminating with a cellular phone associated with the enterprise network;

communicating, by the carrier gateway server to the enterprise gateway server, an indication that the call is being originated or terminated; and

communicating the call routing from the enterprise gateway server to the carrier gateway server.

8. The method of claim 7, comprising informing by the enterprise gateway server, the carrier gateway server of the call routing, wherein the call routing is based on at least one of:

a criteria of the enterprise network; and

a least cost routing determined by the enterprise gateway server.

9. The method of claim 8, wherein the call routing specifies one of routing the call within the carrier network or routing the call into the enterprise network.

10. The method of claim 1, comprising determining, by the carrier gateway server, whether to notify the enterprise gateway server of a call based on information stored in at least one of:

a subscriber profile maintained in the carrier network; and

an application server maintained in the carrier network.

11. The method of claim 1, comprising determining, by the carrier gateway server based on information stored within the carrier network, whether to route a call based on policies set by the carrier network.

12. The method of claim 11, wherein the policies specify at least one of a rule to enable calls to be routed based on service subscription information, a rule to enable calls to be routed using specific resources, a rule to enable calls at specific times, a rule to enable calls to be routed based on specific congestion levels, a rule to enable calls based on identification information of a called or calling party, a rule to enable calls based on location information of the called or calling party, a rule that specifies triggers, and a rule that specifies it is required to record the call.

13. The method of claim 1, comprising determining, by the enterprise gateway server, whether to route the call over dedicated resources based on information stored within the enterprise network.

14. The method of claim 13, wherein the dedicated resources comprise at least one of resources to enable least-cost routing, resources to enable security, resources to enable high performance, resources to address congestion levels, resources to enable priority access and high availability, and resources to enable access to specific enterprise features.

15. The method of claim 1, comprising determining, by the enterprise gateway server based on information stored within the enterprise network, whether to route the call based on policies set by the enterprise network.

16. The method of claim 15, wherein the policies specify at least one of a rule to enable calls to be routed using specific resources, a rule to enable calls at specific times, a rule to enable calls based on identification information of a called or calling party, a rule to enable calls based on location information of the called or calling party, a rule that specifies triggers, and a rule that specifies it is required to record the call.

17. The method of claim 1, comprising determining, by the enterprise gateway server based on information stored within the enterprise network, whether to route the call based on policies set by a called or calling party of the call.

18. The method of claim 17, wherein the policies comprise at least one of a rule to enable calls to be routed using specific resources, a rule to enable calls to be routed at specific times, a rule based on identification information of a called or calling party, a rule to enable calls based on location information of the called or calling party, a rule that specifies triggers, and a rule that specifies it is required to record the call.

19. A non-transitory computer-readable medium comprising instructions for:

coupling an enterprise gateway server in an enterprise network with a carrier gateway server in a carrier network; and

establishing a secure tunnel between the enterprise gateway server and the carrier gateway server, wherein the secure tunnel supports selectable security and encryption specific to requirements of the enterprise network.

20. A system, comprising:

a cellular network including a carrier gateway server; and

an enterprise network including an enterprise gateway server coupled with the carrier gateway server, wherein a secure tunnel is established between the enterprise gateway server and the carrier gateway server, and wherein the secure tunnel supports selectable security and encryption specific to requirements of the enterprise network.
