摘　　要："三不原则"是运营商为推动3G发展出台的重要政策。本文对"三不原则"的实现原理进行了探讨,对终端和网络升级修改的内容进行了介绍,分析了利用SIM卡接入3G网络的用户鉴权过程,2G/3G互操作机制以及为优先接入3G所做的门限参数改进等,并针对"三不原则"的意义和作用做了总结。＂Three No Principle （No change of SIM card, no replacement of phone number, no need for registration）＂is an important policy for the operator to promote 3G. In this article, the implementation theory of the principle has been researched and analyzed, and the major modification aspects on UE and network have been introduced. It also analyzed the authentication procedures for using the SIM card to 3G network, as well as the 2G/3G inter-operation mechanism and the improvement to the threshold parameters for UE＇s preferential access to 3G. In the end, the significant and affects of ＂Three No principle＂ have been summarized.
