随着4G 的逐渐商用化，将出现4G、3G 和2G 长期并存的局面，因而异系统互操作显得尤为重要。针对这种情况，文章基于 TTCN-3(测试与测试控制第三版)设计了一套关于 TD-LTE(时分长期演进)系统到 GSM(全球移动通信系统)的测试例方案，并通过异系统切换来对此进行验证。通过搭建新的仿真平台生成测试流程图与测试报告，并对测试结果进行分析，验证测试平台的优越性和测试方案的合理性与可行性。

With the gradual commercialization of the 4G technology,we will surely see the simultaneous existence of 4G,3G and 2G for a long period of time,therefore Inter-RAT system interoperability is particularly important.In view of such a perspec-tive,this article designs a set of TTCN-3-based test scheme for TD-LTE system and GSM system and verifies it by Inter-RAT system switching.By building a new simulation platform to generate the test flow charts and test reports and analyzing the test results,it verifies the superiorities of the test platform and the rationality and feasibility of this test scheme.
