Abstract

This disclosure provides a system and method for intra-network switching. In some embodiments, a method includes receiving a communication in an Internet Protocol network. The communication is based, at least in part, on a cellular radio technology associated with a mobile switching center. The communication is routed to a network element independent of the mobile switching center.

Claims

1. A method, comprising:

identifying a destination of a message based on a cellular radio technology, a call session comprising the message; and

providing intra-network switching of the message independent of a network element managing the call session.

2. The method of claim 1, further comprising identifying at least a portion of a route of the call session based, at least in part, on the message, the route identifying a network in a same network hierarchy.

3. A method comprising:

receiving a message destined for a mobile device based, at least in part, on cellular radio technology, the message identifying at least a portion of a route of the message;

identifying a first egress node and a second egress node based, at least in part, on the at least the portion of the route, the first egress node preceding the second egress node in the route; and

directly routing the message to the second egress node to eliminate the first egress node form the route of the message.

4. The method of claim 3, the message destined for a mobile device, further comprising updating a routing table associated with the mobile device to eliminate the first egress node for additional messages destined for the mobile device.

5. A method, comprising:

receiving a communication in an Internet Protocol network, the communication based, at least in part, on a cellular radio technology associated with a mobile switching center; and

routing the communication to a network element independent of the mobile switching center.

6. The method of claim 5, the communication including path information identifying a plurality of network elements that the communication was routed through, further comprising modifying the path information indicating that the communication was routed through an associated network element in addition to the plurality of elements.

7. The method of claim 5, wherein the communication comprises a first communication, further comprising:

receiving a second communication destined for a mobile device, the second communication including path information identifying a plurality of network elements that the second communication was routed through; and

routing the first communication based, at least in part, on the path information.

8. The method of claim 7, further comprising:

determining at least a portion of the route to the mobile device based, at least in part, on the path information; and

updating a routing table in accordance with the determined route independent of the mobile switching center.

9. The method of claim 7, wherein the mobile device transmits Universal Mobile Telecommunications System (UMTS) signals.

10. The method of claim 5, the communication comprising a first communication and destined for a mobile device, further comprising:

receiving a second communication including information indicating an updated location of the mobile device, the second communication including updated path information identifying a plurality of network elements that the second communication was routed through; and

updating an associated routed table based, at least in part, on the updated path information.

11. The method of claim 5, wherein the radio cellular technology comprises Global System for Mobile Communication (GSM).

12. The method of claim 5, wherein the radio cellular technology comprises Code Division Multiple Access (CDMA).

13. A method, comprising:

receiving a communication destined for a mobile device, the communication including path information identifying a plurality of network elements that the communication was routed through; and

modifying the path information to indicate that the communication was routed through an associated network element in addition to the plurality of elements.

14. The method of claim 13, further comprising:

identifying a transmitting device based, at least in part on the communication; and

determining at least a portion of a route to the transmitting device based, at least in part, on the path information.

15. The method of claim 14, further comprising:

receiving a response to the transmitting device form the mobile device; and

routing the response based, at least in part, on the at least the portion of the route independent of a mobile switching center.

16. A method, comprising:

representing to a UNC a wireline device as a mobile device, the UNC operable to store location information associated with the wireline device based, at least in part, on the representation; and

providing intra-network switching for the wireline device based, at least in part, on the location information.

17. The method of claim 16, further comprising:

receiving a message from the wireline device; and

updating the message with information identifying a route of the message.

18. A method, comprising:

receiving a message destined for a mobile device, the message identifying location information associated with an origination device; and

updating the message with information identifying a network node that the message was routed through.

19. The method of claim 18, further comprising:

receiving a response form the mobile device, the response identifying location information associated with the mobile device; and

updating an associated routing table with the location information associated with the mobile device to provide intra-network switching for messages destined for the mobile device.

20. A data signal embodied in a carrier wave comprising:

a first segment comprising information identifying an address of a destination mobile device;

a second segment comprising information identifying an address of a transmitting mobile device; and

a third segment comprising information identifying a plurality of network elements that the data signal was routed through.

21. The data signal embodied in the carrier wave of claim 20, wherein the plurality of network elements are operable to provide intra-network switching.

22. A system for providing a development environment, comprising:

memory operable to store routing information; and

one or more processors operable to;

receive a communication in an Internet Protocol network, the communication based, at least in part, on a cellular radio technology associated with a mobile switching center; and

route the communication to a network element independent of the mobile switching center.

23. The system of claim 22, the communication including path information identifying a plurality of network elements that the communication was routed through, the processors further operable to modify the path information indicating that the communication was routed through an associated network element in addition to the plurality of elements.

24. The system of claim 23, the communication comprises a first communication, the processors further operable to:

receive a second communication destined for a mobile device, the communication including path information identifying a plurality of network elements that the communication was routed through; and
