摘　　要：用户经WLAN网络以非授信的模式附着到EPC网络时,如果终端没有或者无法获取用户的SIM信息,则按照3GPP标准定义的认证方法将无法完成用户身份认证,从而不能附着到EPC网络。本文为了解决此问题,研究并应用了一种基于证书的认证方法 EAP-TLS,并给出了这种认证方法的技术原理和流程说明。EAP-TLS认证方法已经成功部署在了某运营商的EPC网络中,运营结果表明本文所研究的认证方法作为对标准认证方法的完善和补充是行之有效的。When a subscriber via the WLAN network attach to EPC network in an un-trusted model,if UE does not or cannot retrieve the subscriber＇s SIM information,in accordance with authentication methods defined by the 3GPP standard specifications,it cannot attach to the EPC network successfully. In order to solve this problem,this paper proposes a certificate-based authentication method EAP-TLS,and gives the technical principles and processes illustrate of this authentication method. The EAP-TLS authentication method has been successfully deployed in a operator＇s EPC network. The applying result shows that the authentication method studied in this paper as the improvement and supplement of standard authentication method is effective.
