A Methodological Approach for IBC System Requirements and Specifications

Objective

The aim of the project was to provide a set of recommendations and guidelines on requirements capture and functional specifications (the BEST method) to assist in the creation of a functional reference model (FRM) for the IBC system.
The aim of the project was to provide a set of recommendations and guidelines on requirements capture and functional specifications (the BEST method) to assist in thecreation of a functional reference model (FRM) for the integrated broadband communications (IBC) system. The proposed method provides a sound technical solution to the current problem, has an evolution path already documented in the use of mathematical languages for verification and, most importantly, provides all the research and development in advanced telecommunications technologies in Europe (RACE) members with a mechanism for ensuring that their assumptions, views and concerns feed into the reference models and so allow consensus to be achieved.
BEST achieved an improved methodological recommendation supporting the requirements capture and functional specification of IBC reference model. The project also developed some notations for conceptual models for projects within the RACE community. The BEST method has been exemplified and elucidated by use of a theoretical worked example, namely, the connection system. This played an important part in the project's internal validation of its recommendations. In addition, a specification of an example FRM function has been produced in close collaboration with other RACE projects.
Technical Summary

The study lasted for two years and the major task for the BEST project in its second year was to apply the method in practice and to disseminate its results a wider forum. Many workshops and seminars have been held to assist other RACE projects in the use of the method. The experience gained in applying the BEST method to real problems resulted in updates, refinements and corrections to the handbook published.

The proposed method provides a sound technical solution to the 'current problem', has an evolution path already documented in the use of mathematical languages for verification and, most importantly, provides all the RACE members with a mechanism for ensuring that their assumptions, views and concerns feed into the reference models and so allow consensus to be achieved.

BEST achieved an improved methodological recommendation supporting the requirements capture and functional specification of IBC reference model. The project also developed some notations for conceptual models for Part I projects within the RACE community.

The BEST method has been exemplified and elucidated by use of a theoretical worked example: 'The Connection System'. This played an important part in the project's internal validation of its recommendations.

In addition, a specification of an example FRM function has been produced in close collaboration with other RACE projects, namely: R1044/1.1 FRM, R1044/1.2 CSF and R1024 NETMAN. A detailed description of this practical worked example can be found in Deliverable 5: 'The Authorisation Worked Example'.

BEST has presented the results of the project at various conferences (IEE SETSS 89 and SDL Forum 89) and workshops and this had led to the exposure of results to other projects.
