The purpose of this paper is to propose a technique to simplify the communications software descriptions written in a procedural language in order to enhance their comprehensibility. Although such a technique was not much studied and discussed in the past, this technique is important to realize high productivity and high quality of the communications software by reducing the complexity of the software description. This paper firstly systematically presents various simplification methods with their principles for the descriptions of the communications software from the viewpoints of their layout, syntactical structures etc. Then, it describes a simplification support system based on these principles for the software specifications written in SDL. Lastly, this paper demonstrates the usefulness and effectiveness of the proposed simplification technique by analyzing the evaluation results of the simplification system.
