Method, apparatus and system for disposing antenna

Abstract

The invention discloses an antenna disposing method, device and system comprising: disposing a first group directional antenna and a second directional antenna on same antenna tower positioned at adjacent area of a first cell and a second cell; the coverage of first directional antenna being at first cell of high speed trunk line, the coverage of second directional antenna being at second cell adjacent to the first cell of high speed trunk line; controlling directional antenna gain of first group directional antenna whose radiation direction points to the first cell larger than gain of directional antenna of the second group whose radiation direction points to the second cell; and controlling gain of directional antenna of the second group whose radiation direction points to the second cell larger than gain of first group directional antenna whose radiation direction points to the second cell. The method, device and system of the invention expand switching area of adjacent cells for covering high speed trunk line.

Description

technical field [0001] The present invention relates to the field of mobile communication network planning in the communication field, in particular to an antenna arrangement method, device and system covering high-speed arterial areas. Background technique [0002] In the mobile communication system, when the mobile station crosses the cells divided by space, in order to ensure the continuity of the call, it needs to perform handover. The handover area is the overlapping area of ​​the two cells where the handover occurs, and the cell reselection and handover are completed in the handover area. Therefore, , the planning of the handover area between adjacent cells is very important to the communication quality of the whole system, especially for the cells covering high-speed arterial lines, because the mobile stations in this area move faster, so the requirements for the handover area are higher. high. [0003] At present, in the high-speed main line area, the distributed an...

AI Technical Summary

Problems solved by technology

[0005] With the development of high-speed railways, maglev trains, etc., the moving speed of the mobile station located in the high-speed arterial area is getting faster and faster. Since it takes a certain time for the mobile station to complete the cell handover, the increase in the speed of the mobile station has a great impact on the handover between adjacent cells. The requirements for the length of the area are correspondingly increased. With the current planning method, it often happens that the mobile station has not completed the cell handover process and has left the handover area, thereby interrupting the communication and reducing the communication quality.
