Methods and apparatus for determining FEMTO base station location
First Claim
1. A method comprising:
- communicating with a re-deployable base station over a wireline network, the re-deployable base station being configured to communicate wirelessly with a mobile station, the mobile station being configured to communicate wirelessly with the re-deployable base station;
obtaining information indicative of a position of the mobile station;
determining a propagation loss between the mobile station and the re-deployable base station; and
estimating a position of the re-deployable base station based on the obtained position informationusing a position location method determined according to the propagation loss.

Abstract
A system and method for determining the location of a re-deployable base station is disclosed. The disclosed system and method allow for accurate determination of the location of a re-deployable base station, such as a femto base station (FBS), using position information obtained from a mobile station (MS) that is communicating with the FBS being located. The position information can include the location of the mobile device as estimated using one or more satellite positioning systems or cellular network based positioning systems. The position information can also include data identifying pilots from base stations and/or other FBS'"'"'s that the MS is receiving. A determination of the propagation loss between the MS and the FBS is used to estimate the distance between the mobile device and the FBS. The location of the FBS is determined based on the received position information and the determined distance between the MS and the FBS.
