1. A mobile station-based method of determining uncertainty, comprising:
- receiving a reported position associated with a wireless transmitter;
measuring one or more measurements related to one or more signals transmitted by the wireless transmitter;
estimating by the mobile station a position of a mobile station at a first point in time;
calculating a range between the reported position associated with the wireless transmitter and the estimated position of the mobile station;
determining by the mobile station a position uncertainty value for the reported position associated with the wireless transmitter, the position uncertainty value representative of a level of correlation between the one or more measurements, related to the one or more signals transmitted from the wireless transmitter, and the calculated range between the reported position associated with the wireless transmitter and the estimated position of the mobile station; and
sending said position uncertainty value to a base station almanac database server.

Abstract
The subject matter disclosed herein relates to determining whether a reported position of a wireless transmitter is sufficiently accurate in accordance with an accuracy metric based at least in part on a calculated range between an estimated position of a mobile station and the reported position and also based at least in part on one or more measurements taken from one or more signals transmitted by the wireless transmitter.

13. A mobile station, comprising:
-
a receiver to; receive a reported position associated with a wireless transmitter, the receiver further configured to receive one or more signals transmitted by the wireless transmitter at approximately a first point in time; and measure one or more measurements related to the one or more signals transmitted by the wireless transmitter; and a processing unit to; estimate at least in part a position of the mobile station at the first point in time; calculate, at least in part, a range between the reported position associated with the wireless transmitter and the estimated position of the mobile station; calculate a position uncertainty value for the reported position associated with the wireless transmitter, the position uncertainty value representative of a level of correlation between the one or more measurements, related to the one or more signals transmitted from the wireless transmitter, and the calculated range between the reported position associated with the wireless transmitter and the estimated position of the mobile station; and send said position uncertainty value to a base station almanac database server. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
