Adaptive adjustment method and device for coverage direction of cell

Abstract

The embodiment of the invention provides an adaptive adjustment method and device for the coverage direction of a cell. The method includes the following steps: calculating the terminal proportion inthe current antenna main lobe direction according to the total number of users in a cell and the number of users in each interval of the cell in the current statistical period; if the terminal proportion in the current antenna main lobe direction is lower than a preset proportion threshold, determining that the coverage direction of the cell is abnormal and finding out the interval with the highest terminal proportion; selecting a target coverage area of which the terminal proportion is higher than the preset proportion threshold and which covers the interval with the highest terminal proportion from the cell according to the main lobe beam width of the cell; and generating antenna weight parameters corresponding to the target coverage area according to the azimuth value of the target coverage area so as to enable a base station to form cell coverage in which the antenna main lobe direction is towards the target coverage area according to the antenna weight parameters. The scheme provided by the embodiment of the invention can improve the coverage of cells and the network perception of hotspot users without climbing on a base station, improve the execution efficiency and reduce thecost.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a method and device for adaptive adjustment of cell coverage direction. Background technique [0002] With the widespread popularization of smart terminals and the increasingly perfect coverage of LTE (Long Term Evolution, Long Term Evolution) network, mobile communication has officially entered the LTE era. How to enable users to enjoy high-quality communication services has gradually become an important research for LTE networks. direction. When the coverage direction of the cell is abnormal, for example, the actual coverage direction is different from the standard coverage direction, or hotspot users are concentrated outside the main lobe, which will cause problems such as low cell coverage and poor user perception. [0003] In order to improve cell coverage and user perception, it is necessary to detect and adjust the abnormality of the...

Problems solved by technology

[0004] However, in the existing technology, on the one hand, due to the wide coverage area of ​​the network, it will consume a lot of manpower and material resources to conduct a network-wide investigation; on the other hand, manually adjust the orientation of the antenna feeder on the site, the execution efficiency is low and the labor cost is high.
