Daidalos - Overview
• Integrate complementary, heterogeneous network technologies to provide pervasive and user-centred access to these services
• Design, prototype and validate infrastructure and components for end-to-end services
• Develop optimised signalling for communication and management support in these networks
• Demonstrate results via user-centred and scenario-based development of technology. Access Technologies

Daidalos Key Concepts
! Key innovation and guiding concepts:!! MARQSMARQS (Integrating Mobility Management, AAA,
Resource Management, QoS and Security)!! VIDVID (Virtual Identities – personalisation at all levels)!! USPUSP (Ubiquitous and Seamless Pervasiveness –
includes context awareness), !! SIBSIB (Seamless Integration of Broadcast – both
technology and service levels)!! FederationFederation (in terms of multiple market players,
“comperation”: competitors in cooperation”)
! Overall integration aspects of these concepts

Daidalos: Scenarios are the red lineStructured in Scenes
Daidalos work must fit in some Scene and Scenario
ITU-T SG13, 7 September 2005© The Daidalos Consortium Page 10
Example: Daidalos Automobile Scenario
Building blocks! Access to personal information and
services inside & outside the vehicle.
! Locating and detecting presence.! Service and content adaptation
based on QoS across operator boundaries.
! Session mobility between terminals (incl. Vehicles)
! Sensor networks for road and hazard warnings
! Broadcast services for entertainment, inter-vehicle safety, and regional traffic information services
Presence detection for automobile mobility applications

VID
issue
• VIDs are used for federation between domains as provider identifiers• VIDs are used for both network and service access, as well as content
• May be extended to other domains, e.g. gaining entrance to building• ID token that contains VID Identifier + encrypted artefact for A4C is used

VID related Issues
! RegID: the user identifier used by operator (or bank or government office) for contract (identifier in home A4C)
! Virtual Identity (VID) – is a representation of the user’s attributes within the system. It contains an identifier together with additional information like a profile, credentials, usage trace, etc.
! VID Identifier: a string that serves as an alias for a user, also called pseudonym, e.g. bart@daidalos
! IDToken: token used to authenticate with certain VID Identifier
VID providers• Their asset is customer trust and customer relationships• Operators, banks and credit card companies may compete in future• They may or may not offer services or network access
ITU-T SG13, 7 September 2005© The Daidalos Consortium Page 16
Virtual Identities in Daidalos! The user knows his RegID and
VIDs. These are his identifications in the legal system and the network, respectably.
! The Operator knows the service but not the User.
! The Billing entity knows the user but not the service.
! The user is protected from the both sides.

Daidalos – Status and Outlook
Status todayStatus today! Specification work in Phase I has been completed! Implementation work is 90% complete! Integration work at the subsystem level is advanced! Several Daidalos publications in journals and conferences! Contributions to standards, e.g. CARD, NEMO, Handover (IETF)! Successful first Audit and Workshop in December 2004
OutlookOutlook! First Integrated “Nidaros” Demo will be shown in December 2005! Daidalos II – due to start in January 2005, End December 2008
# One of two project proposals in area with highest marks# Final negotiations ongoing
ITU-T SG13, 7 September 2005© The Daidalos Consortium Page 18
Potential areas of interest for ITU-T
! Overall NGN Architecture! Pervasive devices, networks and services! FMC! Integration of mobility with broadcast
! Federation allowing a dynamic market environment! Mobility and QoS
! Device and Session (User) mobility, monitoring, fast handover
! Identity Management, Security and AAA! Virtual Identity concept applied across all layers! Single sign-on
! Accounting and billing! session based charging, flow based charging
Daidalos: Evaluate benefits of becoming an ITU-T focus group
ITU-T SG13, 7 September 2005© The Daidalos Consortium Page 19
Possible Deliverables in 2006
! IP-based NGN Architecture! Full mobility and broadcast integration! Quality of Service and Resource Control! Identity Management! Federation for a dynamic market environment
! 2G/3G Transition to IP-based NGN Architecture! Migration strategies! One-number reachability! Roaming and handover! Inter-working components
