Compared with the prior art, the method and the system provided by the invention have the advantages that judgment conditions are relatively sufficient, misjudgment of lifting interference such as interference unit interference can be effectively avoided, and the judgment efficiency and accurately are relatively high. According to the method and the system, the atmospheric waveguide interference judgment is carried out based on background network management performance and engineering parameter data, the cost is low, the timeliness is high, the efficiency is high, and the method and the system are very applicable to daily judgment of the atmospheric waveguideinterference.

Description

technical field [0001] The invention relates to the field of wireless network optimization for mobile communication, in particular to a method and system for locating atmospheric waveguide interference in a TD-LTE network. Background technique [0002] Under certain meteorological conditions, the atmospheric waveguide phenomenon can make the TD-LTE downlink wireless signal propagate very far. Since the propagation distance exceeds the protection distance of the uplink and downlink protection time slots of the TD-LTE system, this remote TD-LT E downlink wireless signal The signal interferes with the local TD-LTE uplink wireless signal. At present, there are two main technical solutions for the determination of atmospheric duct interference: [0003] (1) The local network management analyzes the PRB interference waveform: [0004] Use the TD-LTE local network management to analyze the interference of the cell from the frequency domain. The average uplink interference level i...

Problems solved by technology

[0007] For the local network management analysis PRB interference waveform method, the judgment condition for judging that the cell is interfered by the atmospheric waveguide is a necessary and insufficient condition, and it will lead to misjudgment for lifting interference such as jammers

However, the on-site frequency scanning method of the frequency scanner requires personnel to scan the frequency on site, which consumes a lot of manpower and material resources, is time-consuming and laborious, and has a high cost. It cannot be used as a daily determination method for network optimization professional atmospheric waveguide interference.
