Embodiment
[0032] Such as figure 1 Shown, the method that the present invention proposes is based on MRO data, and it mainly comprises the following steps:
[0033] (1) Calculate overlapping coverage sampling points through MRO data.
[0034] Measurement is an important function of TD-SCDMA system. The measurement results reported by the physical layer can be used by the radio resource control sublayer in the system to trigger events such as cell selection / reselection and handover, and can also be used for system operation and maintenance to observe the operating status of the system. Network equipment shall have the ability to measure the data specified in the measurement report. When the measurement method adopts periodic measurement, the reporting period can be configured when customizing the measurement task.
[0035] For a measurement, the report trigger mode can be event trigger or periodic trigger. If it is a periodic trigger, you need to configure the reporting period; if it ...

The invention discloses a method for calculating and evaluating a network structure problem region through measuring reports. The method is characterized by mainly comprising the following steps that (1) overlapped coverage sampling points are worked out through MRO data; (2) a weighted risk index of a key cell is worked out according to the overlapped coverage sampling points; (3) micro regions of the key cell are found out through bidirectional positioning operation; (4) the interference degree of all micro regions on the network is obtained through the structure damage index algorithm calculation, so the problem region is confirmed. The method provided by the invention has the advantages that great revolution is made on the data source selection, and the sweeping frequency data measurement requiring a great amount of labor and materials is abandoned, the MRO data measurement for directly obtaining on the network management is adopted, the data updating period is very short, the data quantity is very great, and in addition, the coverage rate can reach 100 percent.
Description
technical field [0001] The invention relates to the communication field, in particular to a method for calculating and evaluating network structure problem areas through measurement reports. Background technique [0002] At present, the analysis of TD structure in the industry is mainly based on overlapping coverage analysis and rectification, and its data is realized based on frequency sweep data. The so-called road overlapping coverage refers to: the PCCPCH RSCP difference on the road is less than 6dB, the cell RSCP is greater than -95dBm, and at the same time, the total number of cells that meet the above conditions is greater than 3. However, when actually running the overlapping coverage analysis method, it still has the following defects: [0003] First, because the existing technical solutions mainly rely on frequency sweep data, and the frequency sweep data needs to be manually measured and collected on the road, not only the data collection efficiency is very low, ...
