This paper describes a computer-aided service creation environment (CSCE) for the intelligent network which supports easier graphical specification description for service designers of various skill levels, and service logic program (SLP) generation. The CSCE design concept consists of stepwise service specification description and SLP generation, message sequence chart description language (LSDL: Layered Service Specification Description Language), computer-aided sophisticated interface (IEDs: Intelligent Editors), automatic specification verification and rapid service prototyping. Service specification is described by three steps and in LSDL or SDL, and SLPs are generated through three converters referring to two knowledge databases. Three tests are conducted on the specifications described. The effectiveness of the CSCE is demonstrated by the results that the amount of SLP descriptions for five new practical services using the CSCE is reduced to less than about 20% in LSDL description, compared to C language description.
