Exploring adaptable access in next generation networks

Abstract

An "etiquette" is required but is missing from the planned NGN architecture. An etiquette provides the mechanism to fairly select which access technology to use when multiple access technologies are deployed in the same network. This paper identifies the benefits an etiquette offers, describes how an etiquette can improve NGN over 3 G networks, and explains how standardizing an etiquette for NGN can affect intellectual property issues. Multiple standardization organizations are identified that are addressing similar issues, however none appear to be standardizing etiquettes for NGN. It is recommended that the ITU take the lead in standardizing etiquettes for NGN.
