支持SIM认证的WLAN STA模拟器的设计与实现

Design and implementation of SIM authentication-supporting WLAN STA simulator

为了解决在无线AC(接入控制器)开发与测试过程中出现的多用户终端接入测试困难及测试AC对大量用户的处理性能的问题,介绍了一种支持EAP-SIM(可扩展认证协议-客户识别模块)认证的STA(站)模拟器的设计原理,该模拟器可根据EAP-SIM协议规定,模拟真实SIM卡用户的接入认证流程,实现大量用户接入并认证,对AC进行压力和性能测试。

In order to solve the problems in multi-user terminal access and tests of wireless Access Controller （AC） performances when dealing with large numbers of users in its development and tests, this paper mainly introduces the design principle of a STA simulator that supports Extensible Authentication Protocol-Subscriber Identity Module （EAP-SIM） authentication, In line with EAP-SIM protocol, this simulator simulates the access and authentication flow of real SIM card users, implements the access and authentication of large numbers of users, and performs pressure and performance tests on the AC.
