Abstract
(Englisch)
|
EXODUS seeks to identify a smooth transition path from disparate fixed and second generation mobile systems towards Universal Mobile Telecommunication System (UMTS), focusing on evolution of Core Network capabilities supporting both terminal and personal mobility for a number of services provisioned to selected application sectors (e.g. health care, traveling business).
The transition path is demonstrated using an evolving experimental platform supporting large-scale real users, over multiple islands including switching and service nodes.
The aim of the project is threefold:
·demonstrate terminal and personal mobility, spanning both public and private operating environments, using systems which support voice, data and image applications;
·identify, implement and demonstrate IN functionalities for meeting UMTS requirements;
·identify implement and demonstrate enhancements of and over ATM-based B-ISDN to support mobility management.
Focus is on the Control Plane of the Core Network and on INAP enhancements required to support mobility. This includes enhancements of B-ISDN signaling and deployment of distributed databases, and distributed processing capabilities, together with relevant protocols. This approach is facilitated by the participation in the consortium of the relevant manufacturers. For the radio access network, existing technologies with functional enhancements will be used and no new air interface will be developed. The project takes off basing on the results from RACE II projects on UMTS, IN and B-ISDN.
The experimental platform in EXODUS consists of three islands, two islands in Italy and one in Switzerland based on the Swiss National Host. Sites include the University Hospital in Basel for the Healthcare trials and a the Technical School in Oesingen. The trials have been ongoing during the major part of 1998. The evaluation of the results was based on both objective and subjective data. The Service Performance and Network Performance have been derived from measurements performed in different equipment of the EXODUS platform. The users assessed the Quality of Service and the usability of the mobile multimedia applications and Healthcare applications by answering different and specific questionnaires. The collected data are presented for each applications. The measurements have been processed, analyzed and interpreted; these measurements have also emphasized some of the characteristics of the C-plane in the EXODUS network. Some of the results of this activity were published in various technical papers.
Ascom's overall results from the EXODUS project are the following:
·IN technology for complex and heterogeneous networks.
·Mobility management for future UMTS networks.
·Design, implementation and integration of product quality control plane SW for an Ascom ATM switch.
·General theoretical and practical know-how of the different control capabilities required to deploy and manage multimedia services for 3rd Generation mobile networks.
·National and international contacts and possible future co-operation with project partners. Publicity though publications and public demonstrations.
