4G Plus 4th Generation Platform Launching
Ubiquitous Services

• 4 April 2003
• Herma van Kranenburg

2
Setting
Heterogeneous networks and technology
Each domain connected via IP to an all-IP core
backbone
3
User perspective
User wants always anytime everywhere Optimal and
cheapest connectivity Tailored to circumstancial
needs and capabilities Ambient aware Minimal
botherded, maximal flexibility

Solutionsresearched 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
