摘要
依据3GPP提出的网络接入安全技术规范,分别讨论了2G与3G网络中用户的接入安全机制,重点分析在2G、3G网络共存情况下的漫游用户鉴权,最后对移动网络安全的进一步完善提出了建议。
According to 3GPP security technology specification of access network, the network access security mechanisms in 2G and 3G mobile network is discussed. The roaming user authentication in the case of coexistence of 2G and 3G systems is analyzed emphatically. Finally it presents some proposals to improve the mobile network security.
