Method for movable signal partition coverage

Abstract

The invention discloses a method for movable signal partition coverage. The method is characterized in that by means of relational characteristics between vertical beamwidths and signal coverage dead zones of antennas and relational characteristics between placement heights and gain curves of the antennas, the two antennas different in installation height and emission frequency are adopted and provide services for users in a near zone and a far zone of a cell. The low antenna is high in emission frequency and is responsible for providing the services for the users in the near zone; the high antenna is low in emission frequency and is responsible for providing the services for the users on the edge, and the antenna with the corresponding vertical beamwidth is adopted as the high antenna so as to be prevented from interfering in signals of the users in the near zone. Under the condition that the density of base stations is not changed, the method can be applied to airports, railway stations, tourist attractions, schools and other regions where a great number of users are located, the load capacity of the base stations can be enhanced, the telephone traffic of the antennas can be balanced, service handling pressure on the base stations can be relieved, service quality is improved, and user experience is promoted.

Description

technical field [0001] The invention belongs to the technical field of cellular cells in wireless mobile communication, and in particular relates to a method for realizing mobile signal partition coverage in user access technology in a cellular mobile communication system. Background technique [0002] With the rapid increase of mobile users and the growth of floating population, in some densely populated areas, such as near airports, railway stations, bus stations, etc., the existing base stations often cannot ensure the communication quality of each user; The growth makes the load of the base station too heavy, even unable to meet the needs of user services. At present, the base station layout in the cellular mobile communication network is quite dense (base station spacing is about 1km to 12km), and it will face various difficulties to continue to increase the base station density. However, if a cell can be further subdivided into near area and far area, and different an...

AI Technical Summary

Problems solved by technology

These two types have corresponding problems: for a cell with a set of omnidirectional antennas, the signal of the edge users farther from the base station is very weak, and the signal quality is relatively poor; in addition, when there are many users in the cell, it may exceed the antenna rated load, will significantly reduce the quality of service

For a cell with 3 sets of directional antennas, although edge users can obtain relatively good services, users at the boundary of the three sectors may be in a signal blind area or signal overlap, and continuous switching of signals may cause call drop and Service terminal and other issues
