On the design of interworking reference points for information networking

Providers of telecommunications services will have a need in the future to integrate a variety of applications into their service portfolios. They will make use of reference points, which allow interworking of applications in different administrative domains, like e.g. the Retailer Reference Point developed by TINA-C. Based on experiences with implementations that are compliant to such reference point specifications, the paper presents a new approach for a structured and modular composition of reference points. It allows eliminating overlap in functionality when combining multiple Business Relationships to be supported at one reference point between interacting administrative domains.
