Problems solved by technology

It can be seen that the accuracy of OTDOA positioning depends largely on the reception of PRS signals and the estimation of the first path position. In dense urban scenes, due to the occlusion of buildings, the signal will be reflected, refracted and attenuated multiple times, making the The path experienced by the PRS is no longer a straight path. If the position estimation of the mobile station is still based on the PRS arrival time difference, it will bring a large positioning error

Abstract

The invention discloses a network positioning method and a related device. The network positioning method includes the steps: receiving positioning signals of at least three positioning nodes by user equipment (UE), wherein the at least three positioning nodes comprise at least one piece of auxiliary UE, the auxiliary UE is located within an end-to-end communication range of the UE, and effective position information of the auxiliary UE exists currently; measuring the positioning signals of the at least three positioning nodes, and acquiring measuring results which contain time differences of the positioning signals of the at least three positioning nodes, wherein the positioning signals of the at least three positioning nodes are received by the UE; calculating the current position of the UE according to the measuring results and effective position information of the at least three positioning nodes. According to the technical scheme, the network positioning method and the related device are capable of effectively improving accuracy of network positioning.

Description

technical field [0001] The present invention relates to the communication field, in particular to a network positioning method and related equipment. Background technique [0002] At present, with the continuous development of mobile communication technology, the demand for positioning services is also increasing. The application scenarios of location-based services are showing a trend of diversification, such as emergency positioning, crime location tracking, navigation and traffic control, etc. But no matter how diverse the application scenarios are, the industry's demand for positioning is always to obtain reliable, effective, and fast methods. In other words, easy-to-implement and high-precision positioning technology has always been a hot spot for people. [0003] The development of the Global Positioning System (GPS, Global Positioning System) enables mobile stations with GPS modules to obtain accurate positioning, but the disadvantages of GPS are also more obvious. F...
