Method and device for determining intermodulation interference cell

Abstract

The invention discloses a method and a device for determining an intermodulation interference cell. The method comprises the following steps of: determining all frequency points of the intermodulation product of each order of the cell so as to obtain the distribution density of the intermodulation products on each frequency point of the uplink frequency band; determining the correlation between the uplink interference measurement data of the frequency points of the intermodulation products existing in the uplink frequency band and the distribution density of the intermodulation products on the frequency points; and determining whether intermodulation interference exists in the cell according to the magnitude of correlation. Through the invention, all possible intermodulation components can be calculated according to the actually configured frequency information of a base station system, the occurrence probability of each component and distribution density (or interpreted as the distribution density of the intermodulation components) are calculated by a statistical method, and then the array correlation between the obtained distribution density of intermodulation components and the uplink interference measurement data can be adjusted so as to simply and accurately judge whether intermodulation interference exists in the cell.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for determining an intermodulation interference cell. Background technique [0002] With the ever-increasing demand for voice and data services in the mobile communication system, operators around the world are required to evaluate the network quality, and the quality and capacity of the mobile communication system can be effectively guaranteed by judging the interference caused by the performance deterioration of the network operating devices. [0003] The Global System for Mobile Communications (GSM for short) consists of a Mobile Switching Center (MSC for short), a Base Station Controller (BSC for short) and a Base Transceiver Station (Base Transceiver Station, BTS for short), among them, the number of BTS is the largest, and each BTS is connected to a passive antenna feeder system. The passive antenna feeder system consists of a coaxial connector, a coaxi...
