No．7SSISUP的协议一致性测试系统实现

The Implementation of No.7 SS ISUP Conformance Testing System

针对Ｎｏ．７公共信道信令ＩＳＵＰ（ＩＳＤＮＵＳＥＲＰＡＲＴ）协议的特点，分析了利用传统的分布式测试方法实现ＩＳＵＰ一致性测试系统的困难，并借用渡船测试方法（ＦｅｒｒｙＴｅｓｔＭｅｔｈｏｄ）的思想提出了一种ＩＳＵＰ协议一致性测试的新方法，其主要优点是较好地解决了上下测试器的同步问题。最后描述了基于这种方法实现的ＩＳＵＰ协议一致性测试系统。

In this paper the difficulties in realizing the ISUP conformance test system employing the traditionalabstract conformance test method──Distributed Test Method are discussed on the basis of thecharacteristics of ISUP protocal,and a new method derived from Ferry Test Method to test ISUP protocolimplementation is presented.The merit of the new method is that it solves the problem of synchronizationbetween LT(low tester)and UT(upper tester).At last,an ISUP conformance test system based on thenew method is described in detail.
