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.

Claims

1. A method, comprising:

providing, by an enterprise gateway server, a first routing information to a carrier gateway server, the first routing information comprising at least one routing instruction on how to route a session based on at least one policy, wherein the at least one policy comprises enterprise session routing criteria;

transmitting from the carrier gateway server to a mobile switching network, a second routing information, the second routing information comprising at least one of destination information and session path information for routing the session to a destination, and wherein the second routing information comprises a routing instruction informing the mobile switching network to route the session to the carrier gateway server;

routing, by the mobile switching network, the session to the carrier gateway server; and

routing the session through an enterprise network, via the carrier gateway server, to the destination.

2. The method of claim 1 comprising supporting, by the enterprise gateway server, session routing between a private branch exchange deployed in the enterprise network and a cellular network.

3. The method of claim 2, wherein the destination is the private branch exchange.

4. The method of claim 1, wherein the destination is the enterprise gateway server.

5. The method of claim 2, wherein the destination is the enterprise gateway server via the private branch exchange.

6. The method of claim 2, wherein the destination is the private branch exchange via the enterprise gateway.

7. The method of claim 2, wherein the enterprise gateway server routes to a final destination via the private branch exchange.

8. The method of claim 1, wherein the enterprise gateway server routes to a final destination.

9. The method of claim 1 comprising querying, by the carrier gateway server, the enterprise gateway server for the policy.

10. The method of claim 1 comprising returning, by the enterprise gateway server, the policy associated with a member.

11. The method of claim 7 comprising storing, by the enterprise gateway server, the received session information including information related to the final destination.

12. The method of claim 8 comprising storing, by the enterprise gateway server, the received session information including information related to the final destination.

13. The method of claim 2, wherein the cellular network is a public cellular network.

14. The method of claim 1, wherein the policy is associated with a member of the enterprise network linked to a session origination request.

15. The method of claim 2 comprising providing information for routing the session to the enterprise gateway server via the private branch exchange.

16. The method of claim 1, wherein the second routing information comprises information for routing the session to the mobile switching network.

17. The method of claim 1, wherein the mobile switching network comprises at least one of:

a Mobile Switching Center;

a Softswitch, wherein the Softswitch is comprised of a Media Gateway Controller and a Media Gateway; and

a Mobile Switching Center connected to a Softswitch.

18. A system, comprising:

a cellular network including a mobile switching network and a carrier gateway server; and

an enterprise network including an enterprise gateway server and a private branch exchange coupled therewith,

wherein the enterprise gateway server is coupled with the carrier gateway server, and

wherein the carrier gateway server receives, from the mobile switching network, a session origination request of a session destined to a mobile station and queries the enterprise gateway server for a policy on how to route the session,

wherein the enterprise gateway server returns the policy, wherein the policy comprises enterprise session routing criteria applied to the session,

wherein the carrier gateway server transmits to the mobile switching network routing information comprising at least one of destination information and session path information for routing the session to the mobile station destination,

wherein the mobile switching network routes the session to the carrier gateway server; and

wherein the session is routed to the private branch exchange of the enterprise network by the carrier gateway server.

19. The system of claim 18, wherein the private branch exchange routes the session to the enterprise gateway server.

20. The system of claim 19, wherein the enterprise gateway server routes the session to a final destination via the private branch exchange.
