Embodiment 1

[0065] Embodiment 1 of the present invention provides a method for judging a poor quality cell, see figure 1 , the method includes:

[0066] S110. According to the user plane data transmitted through the S1 interface in the call list, determine the measurement value of the KQI (Key Quality Indicators, Key Quality Indicators) index for measuring the speed of opening the webpage;

[0067] S120. Determine a QoE (Quality of Experience, user experience) value according to the measured value of the KQI index determined in step S110;

[0068] S130, judging whether the QoE value determined in step S120 satisfies the preset poor-quality condition of the bill, and if so, determines that the bill is a poor-quality bill;

[0069] S140, counting the number of bad-quality bills in the cell where the user corresponding to the bill is located, and determining the proportion of poor-quality bills in the cell;

[0070] S150. Determine whether the proportion of poor-quality bills in the cell s...

Embodiment 2

[0094] After judging that the cell is of poor quality, in order to optimize the cell network, it is necessary to determine the main reason for the poor quality of the cell, see figure 2 , Embodiment 2 of the present invention provides a method for analyzing the reasons for the poor quality of the community, specifically including:

[0095] S210. Analyze each poor-quality bill in the poor-quality cell to determine the cause of the poor-quality cell. The specific analysis method is:

[0096] After the cell is determined to be of poor quality in step S150, the reason for the poor quality of the cell is determined by judging whether data in user plane data, control plane data, and MR (Measurement Report, network measurement report) satisfies preset conditions. Wherein, the user plane data is the user plane data transmitted by the bill through the S1 interface; the control plane data is the control plane data transmitted by the bill through the S1 interface; the MR data is the dat...

Embodiment 3

[0111] Embodiment 3 of the present invention provides a method for identifying poor-quality cells based on user-level bills and analyzing the causes of poor quality, see image 3 , the method includes:

[0112] S301. Obtain an xDR bill and MR data from a network side.

[0113] S302. Extract valid fields from the xDR bill, for example, extract ProcedureType and Procedure Status from the S1-MME data of the xDR bill; extract DL DATA, TCP link establishment response delay, The confirmation delay of TCP link establishment, the delay from successful TCP link establishment to the first transaction request, the delay of the first HTTP response packet, and the delay of the last HTTP content packet. Extract effective fields from MR data, such as extracting the carrier numbers of ScEarfcn / ncEarfcn primary / neighboring cells, the reference signal received power of ScRSRP / NcRSRP primary / neighboring cells, and the physical cell identification codes of ScPci / NcPci primary / neighboring cells f...

Abstract

The present invention provides a method and device for judging poor-quality cells, which are used to judge poor-quality cells based on user-level indicators, and solve the problem that the results calculated according to northbound performance indicators cannot be restored to specific users. The method includes: according to the user plane data transmitted through the S1 interface in the call list, determining the measured value of the KQI index for measuring the speed of opening the web page; determining the QoE value according to the measured value of the KQI index; judging whether the QoE value meets the preset call quality. Poor condition, if so, then determine that the bill is a poor quality bill; count the number of poor quality bills in the community where the user corresponding to the bill is located, and determine the proportion of the poor quality bill in the community; judge the Whether the proportion of poor-quality bills in the cell meets the preset poor-quality condition of the cell, and if so, determine that the cell is a poor-quality cell.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for judging a cell with poor quality. Background technique [0002] With the development of long term evolution (Long Term Evolution, LTE) technology, an important indicator for checking network operation status now includes whether the cell is a poor quality cell. Wherein, the poor quality cell is a cell with poor performance and poor user perception in the cellular mobile communication system. Therefore, cells with poor quality are usually the cells that need to be focused on during network optimization. [0003] At present, to determine whether the cell belongs to a poor-quality cell, it is usually judged whether the northbound performance index satisfies a preset condition, and if so, it is determined that the cell is a poor-quality cell. For example, if the cell's eSRVCC (Enhanced Single Radio Voice Call Continuity, enhanced single radio ...
