Abstract:
1. A method, comprising one or more operations implemented by a computer, for ascertaining location determination accuracy in a mobile telecommunications environment, the method comprising: obtaining location determination accuracy data for a plurality of empirical test calls in a geographic region, a location of a wireless station for each test call determined using at least one of a plurality of wireless locating techniques; identifying at least an approximate ratio of wireless locating techniques for the empirical test calls, wherein the identified ratio is based on a comparison of a number of empirical test calls that use a first wireless locating technique with a number of empirical test calls that use at least one other wireless locating technique; receiving data relating to subscriber calls involving wireless telecommunication devices in the geographic region, the data including information relating to location estimates determined using at least one of the wireless locating techniques; and automatically estimating location determination accuracy in the geographic region by combining at least portions of the data relating to subscriber calls according to the identified ratio of wireless locating techniques for the empirical test calls.
