　　提出了一种基于伪基站的 GSM 用户分选实现方案。该方案利用 GSM 移动通信小区重选、位置更新机制，采用伪基站技术，对指定运营商用户进行信令控制，实现有效无线覆盖范围内的用户分选。根据用户的国际移动用户识别码（IMSI），用户被分选为“选通”用户和“屏蔽”用户，选通用户能够正常通信，屏蔽用户无法通信。利用 GSM 分选技术，可以实现区域内 GSM 的可控安全通信，即合法用户可以正常通信，可疑用户的通信被屏蔽。

An implementation scheme for GSM user division system based on fake basestation is proposed. By using cell reselect, location update mechanism of GSM system and with fake-basestation technology for signalling control of the subscriber of specified mobile telecom carrier, this scheme could implement GSM user division in actual coverage. In accordance with IMSI (International Mobile Subscriber Identity), the users are divided into “permitted” or “shielded”users, the permitted users could communicate normally, while the shielded users could not. With GSM user-divsion technology, the controlled safe GSM communication in the cell could be realized, this is, the legitimate users could communicate normally, while the suspicious users are blocked.
