Compared with the GSM network， the two-way authentication mechanism has been added to LTE， and the prevention and control of pseudo base stations are improved. However， due to the shackles of traditional hardware facilities， detection and tracking are expensive and the flexibility is insufficient. Not only that， with the upgrade of communication technology， pseudo base stations are more inclined to be intelligent and miniaturized， which is difficult to detect. In response to the above problems， based on the software radio technology， this paper improves the related pseudo base station identification algorithm and proposes a new LTE pseudo base station identification scheme： Acquiring a key cell of the base station by building a software radio platform and establishing an LTE downlink broadcast information receiving link Relevant information， and the base stationis is distinguished based on the consistent information recognition algorithm. The scheme selected two test scenarios， correctly detected the legal base station， and also detected the information of the pseudo base station， which verified the feasibility of the identification method in this paper. Combined with the advantages of software radio itself， the technology formed in this paper has the advantages of high system upgrade efficiency and cost reduction.
