Method and system for checking and avoiding interference of pseudo base station

Abstract

The invention discloses a method and system for checking and avoiding interference of a pseudo base station. The system for checking and avoiding interference of the pseudo base station comprises an input module, a detection module, a searching module, a judgement module, an execution module and a pseudo base station feature library. The input module carries out statistics on the performance statistics index and screens out bad quality areas; the judgement module screens out a suspected pseudo base station area according to switching between the bad quality areas; the searching module searchesthe updating condition of the suspected pseudo base station area and feature information in the pseudo base station feature library; the judgement module matches the searched updating condition of the suspected pseudo base station area with the feature information in the pseudo base station feature library, and judges whether the suspected pseudo base station is a pseudo base station; for the assertive pseudo base station, the execution module isolates the pseudo base station from the existing network, and checking and avoiding are completed. The pseudo base station can be recognized quicklyand accurately in batch, manual testing and on-site frequency sweep are not needed, time is saved, influence of the pseudo base station on the user perception and the network index is reduced to the hilt, and experience solidification is checked.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to self-positioning and configuration optimization of pseudo base stations. Background technique [0002] Wireless interference is a common network problem in wireless network optimization and maintenance work. Because interference problems have a significant impact on user perception, accurate positioning and troubleshooting of interference problems is a key task for our daily optimization, and it is also the basis for improving network quality and creating value. The common wireless interference is generally uplink interference, and the existing detection and discovery methods are relatively mature. However, it has recently been discovered that there is a monitoring pseudo base station in the existing network, which uses the same frequency band and the same MCC (Mobile Country Code, mobile country code) ), MNC (Mobile Network Code, mobile network number) configurat...

[0009] 2. The impact of pseudo base stations on user perception and network indicators

[0012] A large number of switching failures, reconstructions, and disconnections will inevitably lead to deterioration of user perception, such as video freezes, increased web browsing delays, and even inability to connect

[0013] Second, even if the user does not initiate handover or reselection to the pseudo base station, the power of the pseudo base station itself will interfere with the surrounding cells to a certain extent. Interference; even if there is no modulo three interference in PCI, the RS (Reference Signal, reference signal) signal of the pseudo base station will interfere with the traffic channels of surrounding cells

[0014] 3. Analysis of traditional processing methods

However, for LTE networks with rich signaling, the above method is a bit cumbersome for identifying LTE pseudo base stations that only read IMSI. Customized terminals cannot enter all pseudo base station areas at the same time, and the troubleshooting effect is limited. Even if the pseudo base stations that affect the network are found, they cannot The network will be repaired quickly, and the troubleshooting experience is scattered and difficult to solidify
