A network architecture for personal networks

A Personal Network (PN) is a new concept related to pervasive computing with a strong user-focused view. Whereas several existing technologies can offer solutions to part of a person’s future communication needs, there is very little work on combining these technologies into something a normal user can handle. It will undoubtedly be the network layer that should integrate a person’s all devices and networks into one single network for the person: the Personal Network. This paper introduces a network architecture for PNs that can handle the dynamic and demanding situation a PN is facing. Discussions of some related network layer concepts, issues and possible solutions are given in the end of this paper

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

This paper addresses in detail two possible scenarios for integrating the future mobile telecommunication system UMTS with the evolving broadband fixed telecommunication system BISDN. In the first scenario a mobile-specific access network is envisaged combined with a B-ISDN backbone network. The second scenario uses BISDN 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. I. Introduction UMTS (Universal Mobile Telecommunications System) is currently being designed and standardized. It is intended to be a system capable of providing a diversity of services (up to 2 Mbit/s). In addition to multi-party and multimedia services, UMTS should integrate services as currently being offered by cordless, cellular, (dedicated) paging and private m..
