Abstract

The invention discloses a user positioning method and system based on network signaling data analysis, and belongs to the technical field of data analysis and processing. The method comprises the following steps: performing coarse positioning on the position of a user according to a time advance amount and an arrival angle in signaling data fed back by a user terminal to obtain coarse positioningdata; removing repeated position data in the coarse positioning data to obtain the initial target positioning data; screening abnormal data in the initial target positioning data to obtain target positioning data; dividing a map, and marking a first area and a second area, wherein the first area expresses an area where the user may arrive, and the first area expresses an area where the user cannotarrive; and scattering the target positioning data on the map, and determining a target position of the user in combination with the first area and the second area. Compared with other positioning technologies, the design method of the invention has the advantages of high estimation accuracy and wide application range. At the same time, the method of the invention makes full use of the operator network data and reduces the cost.

Description

technical field [0001] The invention belongs to the technical field of user terminal signaling data analysis and processing in an operator network, and more specifically relates to a user positioning method and system based on network signaling data analysis. Background technique [0002] As the owner of big data, data resources have become an important industrial strategy for telecom operators. However, the data owned by telecom operators is mainly composed of real-time signaling and streaming data, and is generally not the final landing data. Therefore, in the practice of operators' big data applications, the real-time requirements for signaling data processing and analysis are becoming more and more urgent. In actual data analysis, in order to better provide users with high-quality mobile communication services, it is necessary to obtain call quality data information at the user's location. Therefore, the positioning technology of network users plays a decisive role in ...
