基于TTCN的TD-SCDMA RRM一致性测试研究

Conformance testing research on TD-SCDMA RRM using TTCN

协议一致性测试是保证一个网络协议正确实现的关键。在TD-SCDMA系统设备开发和运行维护中,在验证协议实现的正确性及保证不同厂商所开发设备的互连互通方面,为了节省研发和生产开支,实现通信设备与测试标准同步推出,必须在产品开发设计阶段就同步介入测试,因此协议的一致性测试起着重要作用。在描述协议一致性测试方面,树表结合表示法(TTCN)有着显著的特点,本文研究TTCN在TD-SCDMA RRM一致性测试中的应用。通过分析一致性测试系统模型和TTCN测试系统结构,提出了一种基于TTCN的TD-SCDMA RRM一致性测试方法,并给出了测试系统软件构架图。

Protocol Conformance Testing is to validate whether the implementation of a network protocol conforms to what protocol described. Therefore, protocol Conformance is the key to ensure the correct implementation of the network protocol. During the process of developing and running maintenance of the system of TD-SCDMA equipment, in order to cut down the developing and producing cost and realize the synchronization of communication device and testing standard, synchro testing must be performed in the developing phase of the product to ensure the verification of the protocal validity and guarantee the mutual exchanging between different devices of different manufactory. TTCN has prominent characters in describing the protocol Conformance Testing, which therefore is used in the protocol Conformance Testing system. Through the analysis of conformance testing model and the TTCN testing structure, we put forth a new testing method based on TD-SCDMA RRM, and propose a scheme of the software framework of （he testing system as well.
