2 31 October 2000 slide2 PATT Vision A virtual centre of excellence in research on advanced heterogeneous services and fast service development, established as a mutually beneficial collaboration between partners from industry, university and telecom-operators. University NTNU Operator Telenor FoU Telenor Nett Telenor Mobil Industry Ericsson Compaq centre of excellence Rolv Bræk, ITEM Delvis: Vidar Faltinsen/ITEA, Arne Sølvberg/IDI Telenor Konsern : Alf Nilsen Stig Magne Olsen Sjur Malm Oddvar Risnes Geir Melby Lasse Finsaas Tor Arne Bellika Frode Flægstad Styringsgruppe: Høyhastighetsnett Gløshaugen-Tyholt

3 31 October 2000 slide3 What are “advanced” ”heterogeneous” services? “Advanced” means a combination of: traditional telecom-services multimedia services web- and information services messaging services location and context aware services “heterogeneous” means: services over heterogeneous networks: PSTN, IP, GSM, UMTS and services provided by different service providers: Telenor, Teletopia, …(standards are missing in this area) “Advanced” means a combination of: traditional telecom-services multimedia services web- and information services messaging services location and context aware services “heterogeneous” means: services over heterogeneous networks: PSTN, IP, GSM, UMTS and services provided by different service providers: Telenor, Teletopia, …(standards are missing in this area)

4 31 October 2000 slide4 PATT goals Result goals: –A common service platform with open interfaces and access to a heterogeneous set of access and core networks –Service architectures and service execution frameworks that enable fast development and modular deployment/withdrawal of reliable heterogeneous services –A portfolio of differentiated services –Contributions to standardisation of OSA and Parlay –A methodology for rapid service creation –A testbed for interoperability Result goals: –A common service platform with open interfaces and access to a heterogeneous set of access and core networks –Service architectures and service execution frameworks that enable fast development and modular deployment/withdrawal of reliable heterogeneous services –A portfolio of differentiated services –Contributions to standardisation of OSA and Parlay –A methodology for rapid service creation –A testbed for interoperability

5 31 October 2000 slide5 PATT goals Effect goals, achieving: –Competitive advantages –Early experiences with heterogeneous platforms and services –Increased pace of innovation through service experiments (students and others can rapidly design, deploy and gain usage feedback from new services ) –Mutual understanding of problems and solutions –Better standards –Improved recruiting base through better education Effect goals, achieving: –Competitive advantages –Early experiences with heterogeneous platforms and services –Increased pace of innovation through service experiments (students and others can rapidly design, deploy and gain usage feedback from new services ) –Mutual understanding of problems and solutions –Better standards –Improved recruiting base through better education

6 31 October 2000 slide6 Possible research topics How to deal with several service providers: –E.g. who owns the users –How can services from different providers be combined? How to handle several heterogeneous network legs in the same call? Multimedia control Mobility of users, terminals and services Service execution frameworks Principles for service modularity and dynamic deployment withdrawal Principles for user interactions over heterogeneous networks and terminals, XML, IVR, WAP, … Make once – run everywhere; utopia or reality? User acceptance studies on new services Etc … How to deal with several service providers: –E.g. who owns the users –How can services from different providers be combined?
