| description | The present invention provides a method and apparatus for generating time of arrival estimates for use by a wireless communication network for locating the position of a wireless or mobile source ( 102 ) within the service area of the wireless communication network. The mobile source generates time of arrival estimates from data bursts received from base sites ( 100 ) operating within the network. In at least one embodiment, the mobile source ( 102 ), then, communicates the time of arrival estimates for each of the base sites ( 100 ) to the network, from which the location of the mobile source ( 102 ) is determined. In at least some instances, the mobile units additionally determine a variance estimate for each time of arrival estimates, which is representative of the degree of confidence in the time of arrival information being supplied to the network. |
