Abstract

A method and system for configuring a wireless router and a wireless communications network includes establishing connectivity between a wireless router and at least one wireline router. Connectivity between the wireless router and a plurality of neighboring wireless routers is established through the wireline router. The wireless router is configured based on information exchanged with the neighboring wireless routers through the wireline router.

Claims

1. A method for providing connectivity between mobile devices and an Internet protocol (IP) network, comprising:

providing a set of neighboring wireless routers, each operable to receive data packets from a mobile device and to route the data packets to the IP network;

providing connectivity between the set of neighboring wireless routers through a set of wireline routers in the IP network;

exchanging impact information between the neighboring wireless routers to adjust operating parameters of the wireless routers in response to variations in the wireless network;

wherein the impact information comprises traffic engineering parameters for the wireless router;

wherein the traffic engineering parameters comprise at least one of a class-of-service algorithm and a class-of-service resource allocation or a quality-of-service algorithm and a quality-of-service resource allocation; and

wherein adjusting operating parameters of the wireless routers comprises determining, based on the exchanged impact information, operating parameters such that traffic engineering parameters are negotiated among the set of neighboring routers.

2. The method of claim 1, wherein the impact information further comprises interference impact information.

3. The method of claim 1, wherein the impact information further comprises site impact information.

4. The method of claim 3, wherein the site impact information comprises a plurality of geographic parameters, network configuration parameters, service configuration parameters, and antenna parameters.

5. The method of claim 3, wherein the site impact information for the wireless router comprises a plurality of coverage, spectrum, channel, interference, control, and threshold parameters for the wireless router.

6. The method of claim 1, further comprising in response to one of the set of neighboring wireless routers being deactivated, exchanging impact information between the remaining wireless routers in the set and adjusting operating parameters in the remaining wireless routers to account for the absence of the deactivated wireless router.

7. The method of claim 1, further comprising in response to activation of a new neighboring wireless router, exchanging impact information between the neighboring wireless routers and adjusting operating parameters in the neighboring wireless routers to account for addition of the new neighboring wireless router.

8. The method of claim 1, further comprising exchanging impact information and adjusting operating parameters between the neighboring wireless routers in response to a configuration change in the set of neighboring wireless routers.

9. A method for providing connectivity between mobile devices and an Internet protocol (IP) network, comprising:

receiving at a wireless router data packets from a mobile device;

routing the data packets to the IP network;

connecting to at least one neighboring wireless router of a set of neighboring wireless routers through at least one wireline router of a set of wireline routers in the IP network;

exchanging impact information with the at least one neighboring wireless router to adjust operating parameters of the wireless router in response to variations in the wireless network;

wherein the impact information comprises traffic engineering parameters for the wireless router;

wherein the traffic engineering parameters comprise at least one of a class-of-service algorithm and a class-of-service resource allocation or a quality-of-service algorithm and a quality-of-service resource allocation; and

wherein adjusting operating parameters of the wireless routers comprises determining, based on the exchanged impact information, operating parameters such that traffic engineering parameters are negotiated among the set of neighboring routers.

10. The method of claim 9, wherein the impact information further comprises interference impact information.

11. The method of claim 9, wherein the impact information further comprises site impact information.

12. The method of claim 11, wherein the site impact information comprises a plurality of geographic parameters, network configuration parameters, service configuration parameters, and antenna parameters.

13. The method of claim 11, wherein the site impact information for the wireless router comprises a plurality of coverage, spectrum, channel, interference, control, and threshold parameters for the wireless router.

14. The method of claim 9, further comprising in response to the at least one neighboring wireless router being deactivated, exchanging impact information between the remaining wireless routers in the set and adjusting operating parameters of the wireless router to account for the absence of the deactivated at least one wireless router.

15. The method of claim 9, further comprising in response to activation of a new neighboring wireless router, exchanging impact information with the at least one neighboring wireless router and adjusting operating parameters of the wireless router to account for addition of the new neighboring wireless router.

16. The method of claim 9, further comprising exchanging impact information with the at least one neighboring wireless router and adjusting operating parameters of the wireless router in response to a configuration change in the set of neighboring wireless routers.

17. A wireless node for a wireless communications network, comprising:
