5. Levels of Mobility Terminal mobility
end-device has a unique identifier
􀂾communication independent from location
􀂾realized by radio networks
􀂾mechanisms: handover, location management
􀂾enables the user to utilize services from both stationary
end-devices or from mobile end-devices
Individual mobility 􀃆 Concept realized by UPT (Universal Personal Telecommunication)
􀂾participant has a number identifying him uniquely
􀂾communication independent from location and end-device
􀂾participant can use any end-device to receive and to issuecalls
Session mobility
􀂾participant can interrupt his session and later on continue at a different location

For example lets look at the Blackberry devices we have deployed.
One of the pre-requisites for integration into our environment is the Exchange infrastructure (pin to pin is no more secure than using AOL instant messaging – wide open)
We have made a choice not to deploy any custom client software on them
We utilize the Mobitex wireless network (new ones move data over GSM/GPRS networks)
We have deployed over 20 BB gateway Blackberry servers
We have limited security (requested people to install passwords, if people loose it today their device can be wide open)
To deploy this today it would cost us:
