本文件规定了用于3GPP定义的LTE上关键任务服务的信令和协议要求的TTCN-3协议和信令符合性测试。以下TTCN测试规范和设计考虑因素可在本文件中找到:测试系统架构;整体测试套件结构;测试模型和ASP定义;测试方法和通信端口定义的使用;测试配置;设计原则和假设;TTCN风格和惯例;部分实现额外信息(IXIT)格式;测试套件。文档中设计的抽象测试套件基于3GPP TS 36.579-2 [3]中规定的测试用例。3GPP TS 36.579-3 [4]中规定的测试用例不在本文件的范围内。单个测试用例的适用性在3GPP TS 36.579-4 [5]中的测试ICS格式规范中指定。在适当的情况下,属于本规范的抽象测试套件可以引用其他抽象测试套件,例如3GPP TS 36.523-3 [27],用于与承载关键任务服务数据的EPS(LTE)承载相关的要求。本文件适用于3GPP Release 13及以上版本的关键任务服务客户端符合性测试的TTCN开发,直至本文件封面上指出的版本。
The present document specifies the protocol and signalling conformance testing in TTCN-3 for the Mission Critical services over LTE signalling and protocol requirements defined by 3GPP.
The following TTCN test specification and design considerations can be found in the present document:
- the test system architecture;
- the overall test suite structure;
- the test models and ASP definitions;
- the test methods and usage of communication ports definitions;
- the test configurations;
- the design principles and assumptions;
- TTCN styles and conventions;
- the partial Implementation eXtra Information for Testing (IXIT) proforma;
- the test suites.
The Abstract Test Suites designed in the document are based on the test cases specified in 3GPP TS 36.579-2 [3]. The test cases specified in 3GPP TS 36.579-3 [4] are out of scope of the present document.
The applicability of the individual test cases is specified in the test ICS proforma specification in 3GPP TS 36.579-4 [5]). Where appropriate the Abstract Test Suites belonging to the present specification may refer to other Abstract Test Suites e.g. 3GPP TS 36.523-3 [27] for test requirements related to the EPS (LTE) bearers which carry the Mission Critical services data.
The present document is valid for TTCN development for Mission Critical services clients' conformance tests according to 3GPP Releases starting from Release 13 up to the Release indicated on the cover page of the present document.
