WWRF Working Group 2 Activities
STRATEGIC VISIONon future research directions
in the wireless field
WWRF Briefing WG2-br1 · Kellerer/Arbanowski · [email protected] · 03/2005 · WWRF13, Korea page 2
WG2 Vision
• “A wireless world, incorporating 3G systems and beyond, offering end-users I-centric services implemented on top of fully cooperating, easily deployed, compatible and secure Service Execution Environments operated by all authorised parties involved in the value network.”
WWRF Briefing WG2-br1 · Kellerer/Arbanowski · [email protected] · 03/2005 · WWRF13, Korea page 3
WG2 SCOPE
• Following the I-centric view, the white papers provided by Working Group 2 explain in detail what future service architectures have to provide and how such service architectures can be established. To come up with a complete picture, WG2 starts to analyze future service architectures from high level user requirements breaking that down to already available technologies and needed research activities.
• WG2 focuses on the following clusters of research:- Open Service Architecture- Service Capabilities- New Service Building Blocks- Content Analysis and Management- New concepts for I-centric Communications- Mobile Service Platforms (incl. terminal aspects)- Service requirements to the underlying Communication Subsystems
WWRF Briefing WG2-br1 · Kellerer/Arbanowski · [email protected] · 03/2005 · WWRF13, Korea page 4
WG2 Overall plan
• I-Centric Communications
- Personalization, Ambient awareness, Adaptation
- adaptable to each individual communication space
- adaptable to the environment
- intelligence in the system
- integrating service enablers to control and manage the individual communication space
• Current state
- 5 whitepapers available wg2.ww-rf.org (members only)
- Next steps
- Further identification of Wireless World’ building blocks

I-centric Communications Approach
• Human beings communicate with their environment:
- within a set of contexts
- objects and their causality define a context
- an object is every time part of one or many context(s)
- an object can be modified / controlled / queried
• Objects of interest:
- have to be composable rules for context definition
- have to be encapsulated object + interface
- have to be controllable framework

WWRF Briefing WG2-br1 · Kellerer/Arbanowski · [email protected] · 03/2005 · WWRF13, Korea page 10
Terminology Whitepaper
• Purpose
- Defines basic terms used to describe I-centric communications
(framework document)
• Outline
- Definitions- Object- Individual Communication Space- Context, Active Context- Preferences, Ambient Information- Personalization, Ambient Awareness, Adaptation- I-centric Service- Generic Service Elements- Business Model- Service Platform
WWRF Briefing WG2-br1 · Kellerer/Arbanowski · [email protected] · 03/2005 · WWRF13, Korea page 11
Business Model Whitepaper
• Purpose- One business model for Wireless World service architectures
• Outline- What is a business model?
- Definitions and methodology- Functional level vs. Strategic/organizational level vs. Financial level- Integration of models
- Business topology- Intelligence inside network or terminal- Mobility features – mobile service vs. mobile user
- Service lifecycle (creation, deployment, management, billing)- Benefits for operators and users (market value chains / networks)- Draft Business Model for the Wireless World
WWRF Briefing WG2-br1 · Kellerer/Arbanowski · [email protected] · 03/2005 · WWRF13, Korea page 12
Ambient Awareness Whitepaper
• Purpose- Development of integrated concepts for handling situational information
• Outline- Definitions
- Acquiring ambient information– Sensors in network, in devices or in the environment – Human-machine-interfaces, Actors themselves
- Crunching (Interpreting) ambient information– Aggregating in relation to known reference– Communicating and relating to additional situational information – Different weight & ordering of the processing – Multi-modality
