Embodiment Construction

[0017] The present invention will be further described below in conjunction with specific examples.

[0018] A method for evaluating over-covered cells based on LTE soft sampling MR data analysis, the evaluation process includes the following steps:

[0019] Based on MR to collect TA values, calculate the distance d from the UE to the antenna port. Currently, the XDR table uses 1TS as the unit. By calculating the time advance distance corresponding to 1Ts, the distance is equal to: (3*10^8*1 / (15000*2048)) / 2=4.89m; then d=TA*4.89;

[0020] Combined with the information of neighboring cells, calculate the average distance R1 between a single cell and surrounding neighboring cells. Combined with the handover data, filter the adjacent cell sites with handover data, calculate the average distance R between the cell and the adjacent cell, define R as the reasonable coverage radius of the serving cell, and use R1 if there is no handover data in the cell;

[0021] Define N times R ...

Abstract

The invention discloses an over-coverage cell evaluation method based on LTE flexibly collected MR data analysis, and belongs to the technical field of wireless network optimization. The evaluation process comprises the following steps of based on MR, collecting a TA value, and calculating a distance d from a UE to an antenna opening; combining neighboring cell information to calculate an average distance R1 from a single cell to a neighboring cell, then combining switched data to filter out a neighboring station in which the switched data exists, calculating an average distance R from the cell to the neighboring cell, defining that R is a service cell reasonable coverage radius, and adopting the R1 if no switched data exists in the cell; defining that N fold R is an over-coverage area, wherein N is independently set according to a scene difference. MR carries information of TA, RSRP, RSRQ and the like to establish a comprehensive evaluation means so as to position the over-coverage cell, and the purpose of precise recognition and optimization for the over-coverage cell is achieved.

Description

technical field [0001] The invention relates to the technical field of wireless network optimization, in particular to an evaluation method for an over-coverage cell based on LTE soft sampling MR data analysis. Background technique [0002] In the daily optimization, the coverage of the cell is strictly controlled, but the over-coverage is caused by various factors such as the antenna is too high, the setting of the downtilt angle does not match the surrounding environment, the waveguide effect of urban roads, and water surface reflection. Conventional methods are mainly found through DT testing, abnormal cell processing, and customer complaints, but they have relatively large limitations and cannot achieve network-wide fine-grained active discovery. Contents of the invention [0003] The technical task of the present invention is to address the above deficiencies, provide a method for evaluating over-coverage cells based on LTE soft sampling MR data analysis, and establis...
