I-centric communication systems - Rationales


Present telecommunication systems: designed for specific end systems and services( eg. Fax for facsimile,

telephone for telephony, TV broadcasting for TV sets etc)

Since they are generic there is no limitation of the communication space

Controllability, performance and scalability are the resulting problems

Present telecommunication systems are presentation oriented, each of them has its own presentation style

Consequently there is no service integration




Human beings have limited communication spaces

I do not know everybodyI am not interested in everything etc.

in general they are interested in semantic and not presentation of a specific communication system

they need human services to control, communicate, get informed, etc. as a prolongation of their human senses


I-centric communications systems

I-centric communications systems

Future I-centric communication systems:

adaptable to each individual communication space intelligence in the system

adaptable to the environment and locality of the individual adaptable to the life stage of each individual personalized reacting to the human senses integrating services to control and manage the individual communication

space

follow the user-centered design imitating human behavior at best

DESCRIPTION AND GOALSDESCRIPTION AND GOALS

The Service Architecture Working Group (WG2) is a working group within the Wireless World Research Forum (WWRF). The working group exists to gather inputs and views from industry and academia, to synthesize these views, to influence future visions and research priorities, and to share results across the forum.

Since September 2001, the Working Group 2 has worked in the area of service architectures and service platforms for future wireless systems. The WG2 focuses on the user as the driving force in future communication systems following the approach of WWRF WG1 (Human Perspective). Based on a ubiquitously connected world, WG2 investigates how the user can be provided by future systems with an I-centric service environment. The services addressed by WG2 are settled on top of an all-IP environment, addressing the fulfillment of any user demand.

The vision of I-centric communications has been developed to put the individual (“I”) user in the center of all activities a communication system performs. WG2 aims for communication systems, which in the future are able to model each individual, his preferences, and adapt to different situations and resources in time. The developed Reference Model for I-centric communications addresses the individual user, interacting with the objects of their personal communication space.

The reference model for I-centric communications follows a top-down approach starting with the introduction of individual communication spaces and services. It is common understanding that I-centric services have to support ambient-awareness, personalization, and adaptability. WG investigates how future service architectures can provide these features supporting all involved parties of the business chain.


SCOPESCOPE

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


CRITERIA FOR SUCCESSCRITERIA FOR SUCCESS

The dynamic interchange of ideas within the working groupThis can be measured by assessing the number and quality of contributions to the working group, the number of participants, and the level and consistency of contributions. These should be of a level sufficient to sustain the activities of the working group and its value to the forum.

The timely completion of working group outputsThis can be measured through the regular creation, development and release of working group position documents (whitepapers) and by performance to planned schedules for deliverables to other working groups or to the forum.

Influence on key stakeholdersThis can be measured through the adoption of ideas and concepts of WG2 such as standardization bodies, research projects, or products.


DURATIONSCHEDULE & DELIVERABLES

DURATIONSCHEDULE & DELIVERABLES

Duration The Service Architecture Working Group is a standing working

group within the WWRF and will thus exist indefinitely. As required by the WWRF, WG2 will review its charter at least annually and seek approval of the steering board. The WWRF can terminate WG2 at any time should the need arise.

A report on WG activities and progress presented to the plenary at each WWRF meeting.

Schedule Stable, mature WG2 whitepapers archived to the forum web site. Updated releases of WG2 whitepapers under development

continuously. Requirements (documents) will be taken from WG1 and given to

WG3.


RESOURCE REQUIREMENTS WG2 requires the following resources

RESOURCE REQUIREMENTS WG2 requires the following resources

From the WWRF Space and time in forum meetings to conduct WG2 meetings Space and time in forum meetings to conduct meetings with other

groups within WWRF, e.g., other WGs, SIGs, Vision Committee Collection of input contributions and distribution of these to WG

chair and vice-chair WG2 website and document repository including document upload

access for at least the WG chair and vice-chair Support for WG2 email lists and email exploder service

From its members Time and energy to contribute to the work of the working group

and its goals. No guaranteed commitment is required, but member organizations are requested to permit their participants to actively engage in contributing to the success of the working group.


LIAISON/COLLABORATION WITH EXTERNAL ORGANISATION

LIAISON/COLLABORATION WITH EXTERNAL ORGANISATION

WG2 is interested in interacting with external organizations as appropriate to realize its goals. A non-exhaustive list would include: Professional societies and standardization bodies (e.g. IEEE, ACM,

OMA, IETF, OMG, W3C, etc.) - to engage individuals with expertise and interests relevant to the subject matter of the working group

Complementary or similar groups in other fora (e.g. mITF) - to share perspectives and co-ordinate activities toward common visions and research agendas

Research Projects / Research Consortia that work in similar areas provide good opportunities to disseminate ideas of WG2 or to investigate the identified research tasks

The collaboration or exchange of ideas will be initiated by inviting people from respective external organizations to WG2 meetings. WWRF members, which are also represented in other organizations, act as enabler for these kind of liaisons. Interaction with external organizations will utilize any liaison agreements and processes executed by the WWRF.


COORDINATION WITH OTHER WWRF GROUPS

COORDINATION WITH OTHER WWRF GROUPS

WG2 will co-ordinate with at least: Steering Board Vision Committee Other WWRF working groups Special Interest Groups (SIGs)


MEETINGS AND COMMUNICATIONS

MEETINGS AND COMMUNICATIONS

The Service Architecture Working Group will use the following meetings and communication vehicles: Working group meetings, typically 4-8 hours in length,

during each WWRF meeting. The facilities and arrangements for these meetings are the responsibility of the forum.

Interim meetings to progress the work of the working group or its sub-groups may be scheduled as needed either through physical meetings or, more typically, via conference call.

Email lists and exploders will be used to distribute information such as meeting minutes or general announcements of interest to working group members.

A web page within the forum’s website will be maintained for sharing of information and documents.

situation

preferences

adaptation

I-centric communications describe the ability to define and to manage contexts that are tailored to the preferences of single users, in its individual way to interact with a communication system.

Based on the evaluation of ‘profiles’ that describe user preferences, service capabilities, and on sensing information about its actual environment (context), the user can be provided with individualized services for his actual demands.

Self-learning capabilities are used to profile the behavior of users, numerous services or several features of different services are combined on-demand, and appropriate terminals and conversion strategies are evaluated.

Definitions (cont.)Definitions (cont.)

Object An object is a logical representation of hardware or software entity, or even a

representation of a certain individual, and provides well-defined services from the perspective of an (other) individual.

Individual Communication Space The individual communication space of a certain individual is defined by a set of

objects this individual might want to interact with.

Context A context represents a certain ‘universe of discourse’. It defines relationships and

causalities of an individual to and between particular numbers of objects of its communication space.

Active Context A context is active when it is adapted to a certain environment at a certain moment in

time. It defines the relationships and causalities of an individual to a particular number of physical resources at certain a moment in time, in a certain environment.


DefinitionsDefinitions

Preferences Preferences are conditional choices of service characteristics of an object

depending on context and ambient information. Preferences are applied to objects during the activation of a context.

Ambient Information Ambient information is information that can be collected, gathered, or

sensed from the physical environment using the objects of the individual communication space of a certain individual.

I-centric Service I-centric Services define, manage, and (de)activate contexts in an

individual communication space taking ambient information and the preferences of an individual into account. They support an adaptive, personalized, and ambient-aware way to interact with objects in individual communication spaces.


Definitions (cont.)Definitions (cont.)

Business Model A business model is a description of how an entity or a set of entities intend to create

value with a product or service. It defines the product or service, the roles and relations of the entity, its customers, partners and suppliers, and the physical, virtual, and financial flows between them.

Personalization Personalization provides the information for modeling preferences for an individual

communication space in the I-centric system.

Ambient-awareness Ambient-awareness is the functionality provided by an I-centric system to sense and

exchange information about the current environment, an individual is in at a certain moment in time.

Generic Service Elements A GSE is a functional software component that can be used by other GSEs,

services, or applications and it is hosted by the I-centric Service platform. GSEs provide functionalities common to different services and applications to ease and shorten their development process.
