Process flow: Searching an organization's address book on a BlackBerry device

1. A user performs a contact lookup on a BlackBerry® device.

2. The BlackBerry device assigns a RefId to the search request, compresses and encrypts the request, and sends the request

to the BlackBerry® Enterprise Server over port 3101.

3. The BlackBerry Dispatcher decrypts and decompresses the request with the master encryption key of the BlackBerry

device, and sends the request to the BlackBerry Messaging Agent.

4. The BlackBerry Messaging Agent searches the GAL on the Microsoft® Exchange server and retrieves the 20 closest

matches to the contact lookup request.

The BlackBerry Messaging Agent sends the contact lookup results to the BlackBerry Dispatcher.

5. The BlackBerry Dispatcher encrypts the results with the master encryption key of the BlackBerry device, compresses

the encrypted data, and sends it to the BlackBerry Router for delivery to the BlackBerry device.

6. The BlackBerry Router sends the encrypted data to the wireless network over port 3101.

7. The wireless network verifies that the PIN belongs to a valid BlackBerry device that is registered with the wireless

network, and sends the encrypted data to the BlackBerry device.

8. The BlackBerry device sends a delivery confirmation to the BlackBerry Dispatcher, which sends it to the BlackBerry

Messaging Agent.

If the BlackBerry Enterprise Server does not receive a delivery confirmation within four hours, it resubmits the contact

lookup results to the wireless network.

9. The BlackBerry device decrypts and decompresses the contact lookup results with the master encryption key so that

the user can view them on the BlackBerry device or add them to the contact list on the BlackBerry device.
