Problem point positioning method and system based on measurement report

Abstract

The invention discloses a problem point positioning method and system based on a measurement report. The method comprises the following steps: obtaining MRO data and user complaint data reported by a user terminal, and screening a problem cell; obtaining MRO data within a problem occurrence time of the problem cell; analyzing the MRO data within the problem occurrence time of the problem cell, counting the distribution of TAs and AOAs in the MRO data, and counting the occurrence number of sampling points of each MRO data according to that different TAs and AOAs represent different MRO data sampling points; and positioning the problem points of the corresponding TAs and AOAs according to a sequence of the occurrence number of sampling points of each MRO data from large to small. According to the problem point positioning method and system, the problem points can be positioned accurately and efficiently by the distribution statistics of the two measurement amounts of TAs and AOAs in the MRO data, and meanwhile cell service hotspot display, work parameter verification and other auxiliary functions are also available.

Description

technical field [0001] The present invention relates to a method and system for quickly and accurately locating problem areas in problematic cells based on measurement reports (MRO), in particular to a method and system for quickly and accurately locating problematic cell problems based on measurement reports recorded in GSM, TD-SCDMA, WCDMA, and LTE systems point method and system. Background technique [0002] With the rapid development of LTE wireless networks and the advent of the big data era, the number of mobile users is also increasing. At the same time, users' demand for data services is increasing, and their requirements for service awareness are also increasing. In daily network maintenance, TOP cells with poor performance need to be optimized and adjusted. At the same time, many users often complain about poor service perception. The traditional drive test method is mainly to ensure service perception on the main road. The service perception evaluation of a larg...

Problems solved by technology

[0016] In order to solve the problem of positioning accuracy, a fingerprint positioning algorithm has emerged. This algorithm has the advantages of low dependence on the propagation model and station distance, insensitivity to the deviation of a single measurement, and high positioning accuracy. However, it has high requirements for the platform architecture. The cost is expensive, and the algorithm is relatively complex, the adjustment is not very flexible, the data requirements are high, and the analysis time is long. It is suitable for the optimization scenario of large-scale network concentration problems. In some small-scale optimization and adjustment applications, the cost performance is low
