Abstract

The embodiment of the invention discloses a subway positioning method and device based on mobile communication, and the method comprises the steps: firstly, carrying out the calculation, and obtainingan acceleration estimation value of a subway in the operation process and an operation duration estimation value of the subway between a first subway station and a second subway station; determiningthe moment when the subway stops at the second subway station through the receiving level intensity of the mobile terminal in the subway at each moment; correcting the accelerated speed estimated value and the operation time length estimated value of the subway between the first subway station and the second subway station, and obtaining the uniform-speed operation speed of the subway through a correction result; and positioning the position of the subway at each moment according to the correction result and the constant-speed running speed. According to the scheme disclosed by the embodimentof the invention, the estimated value can be further corrected based on the wireless signal characteristics of the mobile terminal in the subway, and a relatively accurate correction result is obtained, so that relatively accurate positioning of the subway is realized, and compared with the prior art, the positioning precision of the subway is improved.

Description

technical field [0001] The present application relates to the technical field of mobile communication, in particular to a mobile communication-based subway positioning method and device. Background technique [0002] Currently, the indoor mobile network absorbs more and more wireless network traffic. In order to improve the quality of mobile communication, it is necessary to optimize the network of this part of the mobile network. In the process of network optimization, it is necessary to locate the test points of indoor application mobile communication, so as to analyze the problems of the mobile network according to the positioning results and realize the optimization of the mobile network. In this case, when optimizing the mobile network covering the subway, it is necessary to locate the subway. [0003] In the prior art, when locating a subway, signal test equipment is usually used to determine the serving cell of the subway, and then, according to the mobile network co...
