智能卡去激活测试问题分析与解决方法

Analysis and Solution of Smart Card Deactivation Test Failure

针对移动通信终端设备检测认证中常见的一类智能卡去激活测试失败问题,通过借助专用测试工具实际比对和验证,深入分析并定位了问题原因,进一步提出了一种通过软件控制的分段降压法。该方法通过了实际验证,并且具有不改动硬件设计,同时不影响其他一致性测项的优点。

Based on a class of common failure issue during SIM/UICC deactivation testing of mobile terminals,a dedicate testing tool and measurement method are used to analyze the fail logs and to compare the possible factors. This paper locates the root cause of the problem through in-depth analysis, and further proposes a software-controlled powerdrop method by two stages. With actual verification result, this method does not impact the hardware design and achives the advantage of consistent conformance testing.
