Embodiment
[0044] The method for accurately evaluating the severity level of frequency scrambling code interference between TD-SCDMA cells of the present invention mainly includes the following steps:
[0045] (1) Collect MRO data and extract measurement reports of the main cell and neighboring cells.
[0046] MRO data is the abbreviation of measurement report sample data, and MRS is the abbreviation of measurement report statistics data. The statistical data of the measurement report refers to the number of original measurement report samples obtained according to certain statistical conditions within a statistical period. MRO measurement reports mainly include three types: intra-frequency measurement report, inter-frequency measurement report, and inter-system measurement report. The main information of the measurement report includes: RNCID, CellID, IMSI, main frequency of the serving cell, frequency currently used by the serving cell, scrambling code of the serving cell, received po...

Description
technical field [0001] The invention relates to the field of communication, in particular to a method for accurately evaluating the severity level of frequency scrambling code interference between TD-SCDMA cells. Background technique [0002] At present, in the field of communication, people infer frequency interference through the frequency reuse distance. The so-called frequency reuse distance refers to the minimum distance between cells that are allowed to use the same frequency when the communication quality requirements are met. With the continuous increase of services and the continuous expansion of base station carrier capacity, the number of frequency reuse is increasing, and the distance of frequency reuse is getting closer and closer, and its original defects are gradually exposed. It mainly has the following three technical defects: [0003] First, because most of the existing technical solutions are calculated based on the relative geographical location of the c...
