Problems solved by technology
In actual situations, the terrain of each cell is different, and the degree of attenuation of the signal at the same distance is often different. Therefore, using this method is prone to misjudgment, resulting in low accuracy in determining missing adjacent cells, making it difficult to adapt to modern network optimization. technological development needs

The invention relates to a method and a device for determining a pairing-neglected neighbor cell in a mobile communication system. The method includes the following steps: S1, obtaining measured levels of all cells in a serving cell; S2, conducting statistic and analysis on the obtained levels of all the cells, and selecting a cell meeting preset judgment conditions as a candidate cell of the serving cell; S3, comparing a cell identifier of the candidate cell and a cell identifier defined as a neighbor cell in advance, and judging a cell identifier of the candidate cell different from the cell identifier of the neighbor cell defined in advance as a cell identifier of the pairing-neglected neighbor cell. The preset judgment conditions comprise at least one of the following: proportional judgment of cell measuring times and total sampling times; cell level judgment; and unique cell judgment. The preset judgment conditions further comprise geographical judgment. The method and the device improve the accuracy of determining of the pairing-neglected neighbor cell.
Description
technical field [0001] The present invention relates to mobile communication technology, more specifically, to a method and device for determining missing adjacent cells in a mobile communication system. Background technique [0002] In the network planning of the mobile communication system, how to configure suitable neighbor cells for the thousands of cells in the existing network has always been a difficult problem for every network planning engineer and network optimization engineer. Whether the adjacent cell setting is reasonable or not will directly affect the handover success rate, handover call drop rate and other KPI indicators, which in turn will affect the call awareness of the users on the network. In an actual mobile communication system, it often happens that some cells should be configured as neighboring cells of the serving cell but are missing due to some reasons. The missing cells are called missing neighboring cells of the serving cell. The phenomenon of ...
