US 8,559,344 B2 · Method and apparatus for dynamically creating and updating base station neighbor lists

Abstract

The invention includes a method and apparatus for creating a base station neighbor list at a target base station in a wireless network including a plurality of base stations. A method includes obtaining information for creating the base station neighbor list, creating the base station neighbor list using the obtained information, and storing the base station neighbor list. The obtained information includes at least one of geographic locations of ones of the base stations, network status information associated with the wireless network, and pilot signal strength measurement feedback information. The base station neighbor list includes a subset of the base stations of the network. The base stations of the base station neighbor list may be prioritized using at least a portion of the obtained information. The base station neighbor list may be updated periodically, or in response to changes to the obtained information. The base station neighbor list is distributed from the base station to wireless user devices served by the base station for use by the wireless user devices in making handoff decisions.

Claims25

Dependent claims

A method for creating a base station neighbor list for use in a wireless network, wherein the wireless network comprises a plurality of base stations including a target base station for which the base station neighbor list is created and a plurality of other base stations available for inclusion in the base station neighbor list, wherein the wireless network is a mesh wireless network in which the base stations are configured for supporting wireless communications between the base stations, the method comprising:

using a processor for:
obtaining information for creating the base station neighbor list, wherein the obtained information comprises base station connectivity information comprising information identifying at least one of the other base stations with which the target base station currently supports a respective wireless connection configured to support transport of user traffic between the target base station and the other base station;
creating the base station neighbor list using the obtained information;
and
storing the created base station neighbor list.
