Head of standardization strategy
Ericsson Group
Standardization – Differnet industry traditions
 Telecom Approach
– Stage 1-3 process
– Arhitectural elements defining
nodes or roles
– Protocols
LME/DTV

 ”IETF approach”
– Directly to protocols
– Flexible toolbox, but architecure
is up to implementations

WCDMA Evolved
 A new downlink high-speed shared channel
introduced in 3GPP release 5 (ready June
2002)
 High bit-rates and reduced delay
– Up to 9 Mbps outdoors
– 14 Mbps peak data rates
 2-3 times data capacity increase
 Integral part of WCDMA
– No need for extra spectrum
– Mobility and wide area coverage

SSO and Federated Business Models - Problem
Statement
 Current Environment:
– Pieces of everyone´s identity scattered across workplace, banks,
credit cards/insurance companies, national ID … mobile operators,
ISPs, Instant messaging applications, content providers … !!!!
– This is true in the real world and more apparent in the internet.
 Consequences for end user:
LME/DTV
– Inconvenience and frustration from keeping track, remembering,
loose and/or forget ID/passwords, Filling in forms with same info,
…
– Security threats from e.g. use of same ID/passwords, …
– Privacy considerations from e.g. disparate policies for ID
management, …

Interoperable federated network identity services
Phase 1: (Q3’02)
Phase 2: (Q2’03)
Phase 3: (Target: H1’03)
Basic SSO
Attribute Sharing
Service Attributes
• ID-FF extensions
• ID-ISS Interoperability
•ID-FF Opt-In Account
Linking
• ID-FF Simplified Session
Management
Specs for identity services:
- alerts,
- contact book,
- calendar,
- presence,
- geo-location,
- wallet,
- etc ...
(Affiliations, Anonymity
and real time metadata
exchange).
• ID-WSF Permissionsbased Attribute Sharing
• Security built across all
the features and
specifications
• ID-ISS Schema/Protocols
for Personal Identity Profile
Service
• ID-FF SSO across auth
