Embodiment Construction

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] As shown in the figure, the present invention provides a positioning method for a mobile station. The final realization carrier is a computer software system.

[0048] The system is divided into two parts, one is the grid library system composed of grid feature database and related calculation modules; the other is the MR positioning system for processing measurement reports (MR) and generating positioning results.

[0049] In the system initialization stage, the positioning system has no data. The main work is completed in the grid library system. When the grid system completes the training of the grid model and forms a raster data feature library with complete data, the MR positioning system is qualified and can run. During this process, the grid library system Regular and irregular system updates can be carried out, and th...

Abstract

The invention relates to the technical field of mobile communication systems, in particular to a positioning method of a city mobile station. The method comprises the following steps of: (11) collecting data of a target city to generate a geographical grid, and calculating grid codes; (12) updating an actual measurement main-neighbor cell dictionary database; (13) updating a geographical grid area propagation characteristic database; (14) synchronizing data in a grid library subsystem; (15) analyzing measuring reports, rejecting invalid records, and selecting city area records; (16) merging and smoothing multiple continuous measuring reports in the same conversation; (17) performing positioning calculation of the indoor mobile station on the conversation generated indoors in the records; and (18) accurately positioning nonpositioned recorded matched grid area propagation characteristic database. In the positioning method, actual measurement data are mined and integrated fully, and the indoor positioning and outdoor positioning of the city are processed respectively by combining with network engineering parameters and urban wireless environment simulation results, so that the positioning accuracy under the urban complex environment is reduced to within hectometer.

Description

technical field [0001] The invention relates to the technical field of mobile communication systems, in particular to a positioning method for an urban mobile station. Background technique [0002] In the mobile communication system, the mobile station in the call state reports its measurement report to the network side at a period of 480ms. The measurement report includes the serving cell where the mobile station is located, the timing advance and its downlink receiving field strength, and up to 6 The color code, frequency point and downlink receiving field strength of a neighboring cell. This information is the basis of all current mobile station positioning techniques. At present, the mobile station positioning technology is mainly based on signal propagation time, radio wave energy attenuation measurement, triangular relationship and calculation technology. [0003] The general positioning methods include signal angle of arrival (AOA) positioning, field strength positi...
