With the rapid development of the field of mobile communication in recent years, the application of the portable device is from the voice and text of the traditional 2G era; to the pictures and web pages of the 3G era; to the video and audio streaming services of the 4G era. With the evolution of mobile communication applications, users and smart devices are increasingly demanding mobile networks. How to use the precious wireless bandwidth and limited base station resources to provide the highest quality wireless communication services and become a global telecommunications The difficult issues that the industry faces together.

In order to make the mobile communication end have better transmission quality, it is an existing technical method to adjust the antenna tilt of the base station to optimize the network quality. The first picture is a schematic diagram of the method for adjusting the signal of the existing base station. The user of the mobile communication terminal 60 is connected to the base station 61 for the call and network related service. If the mobile communication terminal 60 has the internal location of the signal range of the base station 61, In the case of poor transmission quality, the user of the mobile communication terminal 60 can reflect the transmission quality problem through the telecom operator's customer service staff 21 of the base station 61.

An automatic optimization mobile network cell coverage system for measuring field measurement and customer complaint information for adjusting the tilt angle of at least one antenna of a plurality of base stations in a target area, and optimizing the coverage of the mobile network cells, including: a data a database for storing field test data, base station traffic report data, and customer complaint data associated with the target area in a target area; and a server connecting the data database and executing The following procedure: grouping a plurality of base stations into a plurality of base station groups; determining a priority order of the plurality of base station groups according to the customer complaint data in the target area; according to the priority order of the base station groups Calculating the tilt angle recommendations of all antennas of the higher priority base station group, and calculating the tilt angle recommendations of all antennas calculated by the higher priority base station group, calculating all of the lower priority base station groups The inclination of the antenna is recommended; the inclination of all antennas outputting the group of base stations is recommended to an antenna tilt control system, wherein the antenna is tilted The control system for adjusting the inclination of a plurality of antennas located at a base station within the target area. An automatic optimization action network cell method for considering field measurement and customer complaint information, which is used to adjust the inclination of at least one antenna of a plurality of base stations, and optimize the coverage of the mobile network cells, including the following steps: storing in a target area Field measurement data covered by a plurality of base stations, base station traffic report data, and customer complaint data associated with the target area; grouping a plurality of base stations into a plurality of base station groups; according to association with each base station group The customer complaint data of the group determines the priority order of the plurality of base station groups; according to the priority order of the group of base stations, the inclination recommendation of all antennas of the higher priority base station group is calculated, and the reference is made A tilt recommendation for all antennas calculated by the higher priority base station group, a tilt angle recommendation for all antennas of the lower priority base station group; and an inclination recommendation for all antennas outputting the base station group to An antenna tilt control system for adjusting the tilt of an antenna located in a plurality of base stations in the target area.
