Abstract

Examples of the present invention provide a method based on the arrival time difference, user equipment and network devices.The known location information of the device is calculated the second arrival time difference RSTD2. The time synchronization error TAE is calculated based on RSTD1 and RSTD2, and the TDOA positioning is based on TAE based on TAE.The use of this method has subtracted TAE due to base station reasons during the positioning calculation, that is, the time synchronization error caused by the base station reasons can ensure the accuracy of the TDOA positioning.

Description

technical field [0001] The present invention relates to positioning technology, in particular to a positioning method based on time difference of arrival, user equipment and network equipment. Background technique [0002] With the development of communication services, positioning services, as an indispensable part of mobile communication and personal communication services, play an important role. The positioning service is a value-added service that obtains the location information of mobile terminal users through the operator's network (such as LTE network, etc.), that is, the longitude and latitude coordinates, and provides corresponding services for users with the support of the electronic map platform. In recent years, with the continuous improvement of people's material living standards, people's demand for location-based services is also increasing day by day, such as the extensive demand for positioning in many aspects such as security monitoring, emergency rescue,...
