Data flow: Activating a device over the
wireless network
1. A user opens the activation application on the BlackBerry device, and types the appropriate email address and
activation password.
2. The device sends an activation request to the BlackBerry Infrastructure using standard BlackBerry protocols. The
BlackBerry Infrastructure uses SMTP to send an activation message to the user’s email account. The activation
message contains routing information for the device and public keys.
3. The BlackBerry Enterprise Server sends an activation response to the device. The activation response contains routing
information for the BlackBerry Enterprise Server and the long-term public keys of the BlackBerry Enterprise Server.
4. The BlackBerry Enterprise Server and device use the initial key establishment protocol to generate a device transport
key and verify it. If the
BlackBerry Enterprise Server and device mutually verify the device transport key, the activation
process proceeds. The BlackBerry Enterprise Server and device use the device transport key to encrypt further
communication between each other without sending the device transport key over the wireless network.
5. The BlackBerry Enterprise Server performs the following actions:
• sends the appropriate service books to the device so that the user can send messages from and receive messages
on the device
• sends data (such as calendar entries, contacts, tasks, memos, and device options) to the device, if you turn on
wireless organizer data synchronization and wireless backup
For more information about the activation process, see the BlackBerry Wireless Enterprise Activation Technical Overview.
