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

1. A user searches for a contact 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 using 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

for the contact lookup request.

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

5. The BlackBerry Dispatcher encrypts the results using 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.
