WWRF Briefing WG2-br1

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.”


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


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

Current State of WG2‘ WPs

• Whitepapers

- Terminology

- Business Model part of Book of Visions 2004

- Personalization excerpts publ. in IEEE ComMag (Sept04)

- Ambient Awareness

- Adaptability

• Next white papers:

- Generic Service Elements & Enabling Technologies

- Service Architecture


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


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


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

- Identified research tasks


Personalization Whitepaper

• Purpose- Personalized services that automatically reflect user needs

• Outline- Introduction

- Brief definition of Personalization (context, profile, pref., etc.)

- General discussion- What is the profile ? Where is the profile ?- Who accesses the profile? How to secure the profile?- How to learn profile?

- Identification of research issues


Adaptability Whitepaper

• Purpose- Applications adapting dynamically to new situations

(location, time, user needs, network and end-device capabilities)

• Outline- Introduction

- Brief definition of adaptation- List of typical situations when adaptation is needed

a substantial change in characteristics of connectivity,

entering into a new service domain,changing terminal device in the service

session.- List of research tasks

- Identification of generic service elements- Description of generic service elements


Work Plan for 2005++

• White papers / White presentations

- Provide WG2 roadmap and vision towards non-WWRF organizations

• Liaison with mITF Service Platform Sub-Committee- reference model discussion incl. service categories, high level capabilities,

semantic services, generic service elements, features

• Cross working group / SIG activities to harmonize views, terminology, and common scenarios ad-hoc bi/multilateral meetings

• Interim white paper workshops
