Title: 4G Plus 4th Generation Platform Launching Ubiquitous Services
14G Plus 4th Generation Platform Launching
Ubiquitous Services
- 4 April 2003
- Herma van Kranenburg
2Setting
Heterogeneous networks and technology
Each domain connected via IP to an all-IP core
backbone
3User perspective
User wants always anytime everywhere Optimal and
cheapest connectivity Tailored to circumstancial
needs and capabilities Ambient aware Minimal
botherded, maximal flexibility
4Solutionsresearched in project
- Core issues
- Architectural framework federated service control
- Mobility management
- In this area the seamless roaming of users,
sessions, terminals and services over
heterogeneous networks based on different
technologies is studied. (Dynamic, vertical)
handoffs. - Multimedia Session Control
- Multimedia management deals with setup, breakdown
and maintenance of end-to-end QoS enabled
multimedia connections. - Prototype platform proof of concept
- Uniqueness
- Open environment, integrated solutions,
integrating existing SPs and operators
Facilitating Infrastructure at service control
layer 4G Service Platform

- Benefits for Access Network Operator
- Demo at Freeband business event (6 May 2003)
7End-user demonstration
3rd party Service Provider
Internet
4G Service Platform
Jack arrives at the train station offering a WLAN
hotspot. He switches on his laptop and gets
immediate access to the Internet.
End of scenario
8Conclusions
- After one year of 4G
- Good team, challenging research issues, project
progress according to schedule, research focus
for 2nd year. - Nice prelimenary results, good starting point for
coming research period for innovative federated
service control solutions for seamless roaming in
B3G heterogeneous environments. - Further work
- Promising 2nd year lying ahead!
- Please come and see live demonstration
- at Freeband event
