Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0023] Such as figure 1 As shown, the downtilt angle, vertical half power angle and antenna height of the antenna will affect the coverage of the cell. The specific calculation formula is: in is the downtilt angle of the antenna, H is the height of the antenna, L is the coverage radius of the cell, is the vertical half power angle. It is worth noting that the antenna height and vertical half power angle are generally fixed values.

Abstract

The application discloses a method and device for adjusting an antenna downtilt angle, which relates to the field of communication technology and is used to solve the problem that a fixed antenna downtilt angle cannot adapt to dynamic changes in a cell service state. The method includes: determining the traffic volume of the small data packet service and the traffic volume of the large data packet service of the target cell corresponding to the target antenna, wherein the small data packet service is a service whose data packet length is less than the first preset byte, and the large data packet service The data packet service is a service whose data packet length is greater than the second preset byte, and the second preset byte is greater than or equal to the first preset byte; if the traffic volume of the small data packet service is greater than the traffic volume of the large data packet service, then According to the use of control channel resources in the target cell, adjust the downtilt angle of the target antenna; if the traffic volume of the small data packet service is less than or equal to the traffic volume of the large data packet service, adjust the target antenna according to the use of traffic channel resources in the target cell. The downtilt angle of the antenna. This application is applicable to the process of antenna downtilt adjustment.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a method and a device for adjusting an antenna downtilt angle. Background technique [0002] The antenna is an important part of the wireless communication system, and the downtilt angle of the antenna is directly related to the coverage radius of the outdoor cell. A reasonable downtilt angle of the antenna can avoid problems such as weak coverage and overlapping coverage in the cell. In the prior art, the downtilt angle of the antenna is generally set to a fixed value based on the experience of the staff. However, the service state of the cell changes dynamically. For example, at a certain moment, user equipment in the cell mainly uses network services; at another moment, user equipment in the cell mainly uses video services. However, the fixed antenna downtilt cannot adapt to the dynamic change of the cell service status. Contents of the invention [0...
