Abstract

In a wireless communication network, base stations exchange user data for a communication service between User Equipment (UE) and wireless network gateways. The network gateways exchange the user data with Internet Protocol (IP) routers. One of the gateways receives a Border Control Protocol (BGP) message from one of the IP routers indicating a performance issue with an IP address. The network gateway associates the IP address with the communication service and transfers signaling indicating a service issue. A management computer receives the signaling and transfers signaling to the base stations to shed the one gateway for the communication service. The base stations then exchange the user data for the communication service between the UEs and the wireless network gateways except for the one gateway. These other gateways exchange the user data for the communication service with the IP routers except for the IP router having the issue.

First claim

What is claimed is:

1. A method of operating a wireless communication network comprising:
wireless base stations wirelessly exchanging voice or video data with User Equipment (UEs) for voice or video service and exchanging the voice or video data with wireless network gateways for the voice or video service;
the wireless network gateways exchanging the voice or video data with the wireless base stations for the voice or video service and exchanging the voice or video data with Internet Protocol (IP) routers for the voice or video service;
one of the wireless network gateways receiving a Border Control Protocol (BGP) message from one of the IP routers indicating a performance issue with an IP address, and in response, the one wireless gateway associating the IP address with the voice or video service and transferring wireless network signaling indicating a service issue for the voice or video service at the one wireless network gateway;
a management computer receiving the wireless network signaling and responsively transferring additional wireless network signaling to shed the one wireless network gateway for the voice or video service;
the wireless base stations receiving the additional network signaling, wirelessly exchanging additional voice or video data with the wireless UEs for the voice or video service, and responsive to the additional network signaling, exchanging the additional voice or video data with the wireless network gateways except for the one wireless network gateway having the service issue;
the wireless network gateways, except for the one wireless network gateway, exchanging the additional voice or video data with the wireless base stations for the voice or video service and exchanging the additional voice or video data for the voice or video service with the IP routers except for the one of the IP routers having the performance issue.

2. The method of claim 1 wherein the one of the IP routers comprises a Tier One IP router.

3. The method of claim 1 wherein the wireless network signaling identifies the voice or video service with an Access Point Name (APN).

4. The method of claim 1 wherein the wireless network signaling identifies the voice or video service with a Quality-of-service Class Identifier (QCI).

5. The method of claim 1 wherein the one wireless network gateway comprises a Packet Data Network Gateway (P-GW).

6. The method of claim 1 wherein the management computer comprises a Mobility Management Entity (MME).

7. The method of claim 1 wherein the wireless base stations comprise Node Bs.

8. A wireless communication network comprising:
wireless base stations configured to wirelessly exchange voice or video data with User Equipment (UEs) for voice or video service and to exchange the voice or video data with wireless network gateways for the voice or video service;
the wireless network gateways configured to exchange the voice or video data with the wireless base stations for the voice or video service and to exchange the voice or video data with Internet Protocol (IP) routers for the voice or video service;
one of the wireless network gateways configured to receive a Border Control Protocol (BGP) message from one of the IP routers indicating a performance issue with an IP address, and in response, to associate the IP address with the voice or video service and to transfer wireless network signaling indicating a service issue for the voice or video service at the one wireless network gateway;
a management computer configured to receive the wireless network signaling, and in response, to transfer additional wireless network signaling to shed the one wireless network gateway for the voice or video service;
the wireless base stations configured to receive the additional network signaling, to wirelessly exchange additional voice or video data with the wireless UEs for the voice or video service, and in response to the additional network signaling, to exchange the additional voice or video data with the wireless network gateways except for the one wireless network gateway having the service issue; and
the wireless network gateways, except for the one wireless network gateway, configured to exchange the additional voice or video data with the wireless base stations for the voice or video service and to exchange the additional voice or video data for the voice or video service with the IP routers except for the one of the IP routers having the performance issue.

9. The wireless communication network of claim 8 wherein the one of the IP routers comprises a Tier One IP router.

10. The wireless communication network of claim 8 wherein the wireless network signaling identifies the voice or video service with an Access Point Name (APN).

11. The wireless communication network of claim 8 wherein the wireless network signaling identifies the voice or video service with a Quality-of-service Class Identifier (QCI).

12. The wireless communication network of claim 8 wherein the one wireless network gateway comprises a Packet Data Network Gateway (P-GW).

13. The wireless communication network of claim 8 wherein the management computer comprises a Mobility Management Entity (MME).

14. The wireless communication network of claim 8 wherein the wireless base stations comprise Node Bs.
