Abstract

The invention discloses an automatic update and optimization device and method including a fingerprint library, selects a certain amount of test data, uses the latest MR fingerprint library to perform positioning; collects positioning data sets and drop point data sets; and identifies abnormal feature data Rule mining, testing and verification; generation of update instructions; automatic update optimization to form a new fingerprint library; cyclic update verification. The present invention is based on the statistical analysis results of big data, comprehensively judges, and obtains updating and optimization suggestions. As an optimization method for initial database construction, based on big data technology, it has high efficiency and good results, and realizes the automation of the whole process without manual participation, which greatly saves human resources and computing resources, etc.; it ensures the timeliness of updates and the accuracy of positioning. There is no need to re-build the database, and it can ensure that the excellent part of the grid database after the previous optimization is always maintained, continuously accumulated, and realizes the function of iterative optimization. With continuous use, the positioning effect is getting better and better.

Description

technical field [0001] The invention relates to an update and optimization technology of a fingerprint library, in particular to an automatic update and optimization device and method including a fingerprint library. Background technique [0002] The latest mainstream technology that can provide more accurate location capabilities for operators is the fingerprint positioning technology based on MR; MR refers to the mobile terminal periodically reporting to the base station in the form of MR at a certain time interval on the service channel through the control channel The base station uploads the downlink information reported by the terminal and the uplink physical information collected by itself to the base station controller for the downlink signal strength, quality and other information of the cell where it is located, and is collected and counted by it. Taking the TD-SCDMA network as an example, each MR mainly includes uplink and downlink received signal code power, uplin...
