Method and system for confirming interference between base stations of mobile communication system

Abstract

The invention provides a method for promoting computation accuracy for interference between cellular mobile communication system base station, computation device for accomplishing the method, base station including the computation device and radio communication system. In the invention, analyzing a good many of shortcomings combining practical network topology structure according to existing definability , calculating accumulating interference of multiple interference base station to present interference base station, simultaneously considering transmission model between interfered system base station and terminal, determining the maximum interference the interference base station can bear from coverage confined angle, further evaluating the method for interference avoidance minimum separation. Definability computation accuracy is dramastically promoted in the inventive interference definability analysis method compared to traditional MCL analysis method, which provides assurance for quickly and accurately evaluating interference between different mobile communication system base stations.

Description

technical field [0001] The invention relates to a method for deterministic analysis of interference between mobile communication systems, in particular to a method for improving the accuracy of interference calculation results between base stations of different mobile communication systems by improving the traditional method. Background technique [0002] With the transition of mobile communication from the second generation to the third generation, various new technologies are continuously produced and applied, and radio frequency resources are becoming increasingly scarce, so the research on radio frequency interference in mobile communication networks is becoming more and more important. There are many kinds of interference, such as the existing frequency resources occupied by the original dedicated radio system, improper network configuration of different operators, problems with the setting of the transmitter itself, overlapping cells, the environment, electromagnetic co...

Problems solved by technology

[0038] 1) The interference analysis is limited to a single station. In the actual network, the base station of the interfered system will be interfered by multiple adjacent base stations of the interfering system at the same time, so there must be a certain error in the interference statistics;

[0039] 2) If the maximum interference that the interfered system can tolerate is evaluated by the sensitivity deterioration standard, there is no uniform regulation on how to determine the sensitivity deterioration standard of the base station receiver, and different standards have great differences in the calculation results;

[0041] To sum up, there must be certain errors in evaluating the interference between base stations of different systems through the deterministic analysis method in the prior art, which greatly restricts the accuracy of interference analysis
