A method and device for automatic optimization of adjacent cells

Abstract

The invention provides a neighboring area automatic optimization method and apparatus. The method includes the steps of determining a main serving cell and a list of candidate neighboring areas corresponding to the main serving cell; scoring every candidate cell on the list of the candidate neighboring areas according to candidate neighboring area switching data, candidate neighboring area measurement report data and / or candidate neighboring area cell spacing data; sorting the candidate cells on the list of the candidate neighboring areas according to the score of every candidate cell; selecting M candidate cells as neighboring areas corresponding to the main serving cell the from the list of the candidate neighboring areas according to sorting results, wherein M is the maximum number of needed neighboring areas of the main serving cell. The neighboring area automatic optimization method and apparatus takes the influence of the candidate neighboring area switching data, the candidate neighboring area measurement report data and / or the candidate neighboring area cell spacing data on neighboring area selection into comprehensive consideration, effectively improves the neighboring area optimization efficiency and accuracy and improves user perception.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for automatically optimizing adjacent cells. Background technique [0002] In the mobile communication system, when the mobile station transfers from one cell to another during the call process, or when wireless transmission, traffic load adjustment, activation operation maintenance, equipment failure, etc. occur, in order to keep the communication uninterrupted, the communication network The control system will start the switching process to ensure the service transmission of the mobile station. In the TD-LTE network, the user can only switch to the configured neighbor cell of the current serving cell, so the correct neighbor cell relationship can ensure that the mobile phone at the service border of the cell can switch in time, obtain switching gain, and reduce network interference , thereby improving network service quality and ensuring stable...

Problems solved by technology

[0012] The existing method of planning (or optimizing) the relationship between neighboring cells according to the geographic location (distance between cells) considers too single influencing factors, only considering the distance between cells, and does not consider the number of handovers between cells, handover performance, and overlapping coverage areas. Therefore, there are many unreasonable neighbor relations in the automatically optimized neighbor relationship, and more manual correction is required, which is inefficient.
