    • A system and method of estimating the position of a mobile terminal (MT) operating in a radio telecommunications network. Expected Received Signal Strength (RSS) values are predicted by a computer-aided prediction tool, and/or are measured by a test MT from base station transceivers. The predicted and measured RSS values are then tagged to indicate whether each value was predicted or measured. The RSS values are then stored at a plurality of locations in a database. When RSS measurements are received from the MT being located, a covariance matrix is used to compute metrics for the locations in the database. If more than a threshold percentage of the locations were populated with measured values, a Maximum-Likelihood (ML) estimator is used to estimate the position of the MT. If fewer than the threshold percentage of locations were populated with measured values, a Minimum-Mean-Square-Error (MMSE) estimator is used to estimate the position.
    • 一种估计在无线电信网络中操作的移动终端(MT)的位置的系统和方法。 预期接收信号强度(RSS)值由计算机辅助预测工具预测,和/或通过来自基站收发器的测试MT测量。 然后将预测和测量的RSS值标记,以指示每个值是预测还是测量。 然后将RSS值存储在数据库中的多个位置。 当从位于的MT接收到RSS测量时,使用协方差矩阵来计算数据库中位置的度量。 如果超过阈值百分比的位置用测量值填充,则使用最大似然(ML)估计器来估计MT的位置。 如果使用测量值填充位置的阈值百分比,则使用最小均方误差(MMSE)估计器来估计位置。
