    Abstract: 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.

    Abstract translation: 本发明提供一种用于产生无线通信网络使用的到达时间估计的方法和装置，用于定位无线或移动源（102）在无线通信网络的服务区域内的位置。 移动源从从网络中工作的基站（100）接收的数据突发生成到达时间估计。 在至少一个实施例中，移动源（102）然后将每个基站（100）的到达时间估计时间传达到网络，确定移动源（102）的位置。 在至少一些情况下，移动单元另外确定每次到达估计的方差估计，其表示提供给网络的到达时间信息的置信度。
