Abstract

The invention relates to a method for protecting a wireless location based on the information integration, which relates to mobile terminal wireless location technology. It is achieved through the following programs. Station measures the mobile terminal values of TDOA and AOA and estimates TDOA value by Chan and Taylor arithmetic respectively. Fore location estimated values of TDOA (Chan), TDOA (Taylor), TDOA (Chan) / AOA and TDOA (Taylor) / AOA are obtained combining with AOA, and sent respectively into the first and second tier of data integration for treating. The results of two-tier data integration and the estimated values of TDOA (Chan) and TDOA (Taylor) are sent into the fourth tier to calculate the weighted coefficients. According to the results, the best positioning is selected to be the mobile terminal location.

Description

technical field

[0001] The invention belongs to the technical field of wireless communication, and in particular relates to the wireless positioning technology of a mobile terminal. technical background

[0002] In the 3G cellular mobile communication system, more and more network services depend on the location information of the mobile station (MS). Therefore, the wireless location technology based on the cellular network to estimate the location of the MS has attracted extensive attention in recent years. Now several network-based positioning methods, such as field strength positioning method, radio wave time of arrival (TOA) positioning method, time difference of arrival (TDOA) positioning method and angle of arrival (AOA) positioning method, can be applied to the position estimation of mobile users. . However, in different channels and network environments, the performance of these basic positioning technologies is different, and there is no one technology that can sho...
