Method, apparatus and system for dividing cofrequency interference protection band

Abstract

The invention, which relates to the field of wireless communication, discloses a method, apparatus and system for dividing a cofrequency interference protection band. The method comprises: dividing a plurality of base stations into re-farming-region base stations and non-re-farming-region base stations; determining base stations having the cofrequency interference with the re-farming-region base stations in the non-re-farming-region base stations as cofrequency interference base stations; and determining base stations enabling the switching relationships with the cofrequency interference base stations to be larger than a switching threshold among the re-farming-region base stations as non-re-farming cofrequency interference protection band base stations. According to the invention, the base stations are classified into the re-farming-region base stations and the non-re-farming-region base stations, the base stations having the cofrequency interference with the re-farming-region base stations are determined from the non-re-farming-region base stations, non-re-farming base stations are determined from the re-farming-region base stations according to switching information of the re-farming-region base stations and the cofrequency interference base stations, and the cofrequency interference protection band base stations are set. Therefore, the cofrequency interference caused during the spectrum resource re-farming process can be alleviated and the network quality and the user experience can be guaranteed.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, device and system for dividing co-channel interference protection bands. Background technique [0002] Frequency resources of mobile networks are becoming more and more tight, especially low-frequency frequency resources below 1 GHz, making it difficult for operators to obtain more frequency resources to deploy new-generation mobile communication networks. Therefore, network refarming in the low-frequency band, that is, deploying a new generation of mobile communication networks, has become an inevitable choice for network evolution of operators. However, existing 2G / 3G services need to go through a transition period before they can be migrated to 4G networks. Therefore, for cities with tight low-band spectrum resources, operators deploy 4G networks in high-frequency bands; for rural areas with sufficient low-band spectrum resources, operators Deploy 4G ne...
