B-ISDN to the Cell Site Switch versus B-ISDN to the Mobile Terminal

摘要

This paper addresses in detail two possible scenarios for integrating the futuremobile telecommunication system UMTS with evolving broadband fixed telecommunication system B-ISDN. In the first scenario, a mobile-specific access network is envisaged combined with a B-ISDN backbone network. The second scenario uses B-ISDN basic call facilities throughout the entire network, including the mobile access part. The two scenarios are described in detail and a comparison at functional level is made. This comparison is complemented by a performance study of a non-trivial handover procedure in a high-traffic public environment.
