Problems solved by technology

[0018] 1) The accuracy of the azimuth parameter value is low
The parameter value of the antenna azimuth angle depends on the simulation accuracy of the network planning, and the simulation accuracy is limited by the map accuracy and the propagation model, and usually has a large error with the actual situation, so the parameter value of the azimuth angle of the base station antenna does not meet the expected coverage scope
[0019] 2) It will reduce the network coverage efficiency
Because the network planning simulation does not consider the actual traffic distribution of the existing network, and only meets the goal of network coverage, the main coverage direction of the base station antenna will deviate from the traffic concentration area, resulting in no coverage or poor coverage in places where traffic needs to be concentrated; Areas with less traffic or no traffic have good coverage, which reduces network coverage efficiency and wastes coverage resources

Description

technical field [0001] The invention relates to the field of wireless mobile network planning optimization, in particular to a method and equipment for determining the azimuth angle of a base station antenna. Background technique [0002] As the upsurge of mobile Internet hits rural areas, the rural market has become a new growth blue ocean for mobile operators, and 4G network construction continues to extend to rural areas; however, due to the vast area of ​​rural areas, it is impossible for operators to build networks like cities In order to achieve high-density seamless coverage, it is necessary to ensure coverage of places where users are relatively concentrated during network coverage, so coverage optimization plays an important role. [0003] In coverage optimization, the azimuth angle of the base station antenna is a very important parameter. The azimuth angle of the base station antenna determines the main coverage direction of the cell; adjusting the azimuth angle o...
