USIM卡的鉴权需求对GSM/TD-SCDMA/TD-LTE融合网络影响

摘要

借助存量GSM/TD-SCDMA用户，保证GSM/TD-SCMDA和TD-LTE网络业务的一致性和连续性，是TD-LTE网络建设的主要原则之一。本文首先理论介绍3GPP定义USIM卡在GSM/TD-SCDMA融合网络中鉴权与加密关键技术和TD-LTE的鉴权与加密原则，其次讨论USIM卡在GSM/TD-SCDMA/TD-LTE网络中互操作时的鉴权与加密需求，最后提出利用UDC HLR解决方案建设GSM/TD-SCDMA/TD-LTE融合用户数据库解决USIM卡在GSM/TD-SCDMA/TD-LTE互操作时的接入网安全问题。%Making full use of the GSM/TD-SCDMA subscribers, which can ensure the consistency and continuity of GSM/TD-SCDMA and TD-LTE network, is one of the main principles of TD-LTE network construction. Firstly, the paper introduces the authentication and security mechanisms of UMTS subscribers in GSM/TD-SCDMA network, which is deifne by 3GPP, and the security features and the security mechanisms of TD-LTE. Secondly, the paper discusses the authentication and security mechanisms of UMTS subscribers in the converged network of GSM/TD-SCDMA/TD-LTE, especial for the authentication and security mechanisms of UMTS subscribers switching between GSM/TD-SCDMA and TD-LTE. Finally, the paper proposes the architecture scheme that using the UDC HLR to resolve the network access security for UMTS subscribers in the converged network of GSM/TD-SCDMA/TD-LTE.
