Problems solved by technology

In addition, signal leakage will also cause cell interference, causing handover failure
[0004] The existing inter-cell interference control method is limited to manual regulation, that is, the staff conducts observations in the background and sets with reference to the observed data to adjust the mutual interference between cells
Using this method not only wastes a lot of manpower and material resources, but also cannot achieve accurate control, and there are great human factors

Embodiment Construction

[0023] When the present invention automatically controls the cell interference caused by the improper coverage of the adjacent cell's eNB and the cell interference caused by the signal leakage of other cells, the SON service unit is used to collect the interference measurement information, and the interference cell is determined according to the collected interference measurement information. And notify the eNB to which the interfering cell belongs to adjust the cell interference, so as to reduce the interference generated by the interfering cell on the observing cell.

[0024] The present invention is described in detail below in conjunction with accompanying drawing:

[0025] refer to figure 1 and figure 2 as shown, figure 1 It is a schematic diagram of automatic control of cell interference when a centralized SON service unit is used, and the SON service unit exists independently of the eNB; figure 2 When adopting centralized SON service unit, the flow chart of automat...

Abstract

This invention discloses a method for automatically controlling the interference from a plot. In this invention method, a self-organizing network service unit determines the interference plot which produces interference to a selected observation plot, and then gives an advance to the long-term evolution base-station, which the interference plot belongs to, to regulate the interference plot, so reducing the interference from the interference plot to the observation plot. This invention method improves the abilities of the network and saves man-power and material resources with lowering maintenance cost.

Description

technical field [0001] The present invention relates to a method for automatically controlling cell interference, in particular to a method for automatically controlling cell interference in a Long Term Evolution (LTE) mobile communication system. Background technique [0002] Self Organized Network (SON for short) is a technology for automatic network configuration and optimization, which is characterized by self-configuration and self-optimization. The application of SON technology in LTE enables LTE base stations (e-Node B, eNB for short) to automatically configure network parameters according to certain measurements, and automatically optimize according to network changes, thereby optimizing network performance and saving a lot of manpower and material resources. Currently, there are three types of SON structures: distributed, centralized, and hybrid. Among them, in the distributed structure, the SON service unit exists in each eNB; in the centralized structure, the SON...
