Beyond 3G?
• B3G is defined as the integration of existing systems to interwork with
each other and with a new interface.
• Pers stands for Personalization and this topic is under research in
MAGNET (My personal Adaptive Global NET) project
Convergence is really what 4G is all about!!

System and service adaptation
• Just bought a new device, or
moved it to another location?
– It’s supposed to JUST work…
• Trying to figure out what
service to use?
– Why did I pick the busy printer??
• Ever wished your device would
do what you wanted to do, and
not what it was programmed to do?
– Why did I forget to put in on silence when going
to the movies?

Adapting to the context of the user
Discovering, maintain and providing context information is
a key issue in achieving true context awareness

Adapting security levels
Security level is influenced by its context, e.g.
•
•
Device capability and resources, which may be limited
What implications will it have, if the data is being stolen, tampered with etc.?
– Type of application used
– What data is transferred
•
What means of communication am I using?

To be or not to be trusted
Trust comes in many forms!
And plays an important role in (federated) PN’s
Do we trust this guy?

Ensuring privacy
• Big brother is watching???
– Or is it my neighbour?
• How do we achieve system and service
level adaptation while ensuring privacy?
