Document IPW-10 User Identification Solutions in Converging Networks Mike Pluke Castle Consulting Ltd. ETSI Specialist Task Force STF 157 Leader of :

ETSI STF 157 The Human Factors group within the European Telecommunications Standards Institute (ETSI) is leading this work. The Specialist Task Force comprises 3 people funded to study “User Identification Solutions in Converging Networks”and produce an “ETSI Guide” document on the topic.

The Terms of Reference Discover real user requirements for user identification Develop an implementation-free expression of these requirements Identify potential solution options Create an implementation “Roadmap” for solutions Solutions must work in a competitive environment

So What Is The “User Identification” Issue The number of communications systems is increasing Each system has its own identification system Telephone Numbers mean very little Contacting people isn’t necessarily getting easier Identification-system developments are uncoordinated

A Typical Case A fixed telephone on their office desk A mobile telephone A fixed (shared) telephone at home An address used for work purposes A personal address used at home A person can have:

Communicating Today

The caller has to guess the most successful way to communicate Most callers don’t know all the user identifiers Terminals linked to communication type User identifier schemes linked to communication type Some user identifiers linked to terminals Some user identifiers portable – telephony Some user identifiers linked to provider – Terminals/user identifiers linked to users’ roles What’s Wrong?

Solution Attempts Supplementary services can match people to locations e.g. Call Diversion Mobility solutions can map people to roles e.g. UPT solutions can locate the called party on one of a group of terminals BUT frequently these systems give the wrong results

Many solutions lock users to 1 provider Proprietary solutions are incompatible Most solutions rely on fixes applied to legacy systems Most solutions are unfriendly – to the caller and/or called party There is probably no fully comprehensive global solution Problems With Current Solutions

Human Communication Needs Modern communications systems can create new communication needs BUT Basic communication needs have changed very little since the dawn of man

Historic Communications Needs People have always needed to contact: An Individual “Mary Jones” A Role A local locksmith A Place “23 Dearing Lane”

Tomorrow Individuals, roles, groups and places People will still need to contact:

People Not Terminals “People are outsiders in the current communications revolution. Computer hosts, pager terminals and telephones are addressable entities throughout the Internet and telephony systems.” Extract from “The Mobile People Architecture” from Stanford University

High-level User Requirements A unified way of setting up a communication Reduce the complexity for the calling party Make it easy for the called party to manage their communications Give more options to the called and calling parties

What’s Needed? One user identifier per individual or role An integrated user identifier search mechanism Recognise that Martin Böcker = Martin Boecker Protect privacy of personal data Protect location privacy Automatic capture of user identifiers Intelligent agents to manage complexity for the calling and called parties ……

The User Identifier In Use This format is not a proposal The User Identifier must be unique The format should be “user friendly”

How It Might Be?

What next? ETSI STF 157 will continue to work on refining the user requirements for User Identification solutions At the same time potential solutions will be investigated to validate the practicability of the requirements A draft ETSI Guide will be available in August 2000 Publication is likely in October 2000

What next? ETSI STF 157 is very keen to liaise with all groups with an interest in this area We are also very happy to receive ideas from individuals within these groups My (as STF Leader) is: ETSI HF Chairman is Knut Nordby:
