Feature and Technical Overview

BlackBerry Enterprise Server process flows

The BlackBerry device compresses and encrypts the request, and sends the request to the BlackBerry Dispatcher over port 3101.

3.The BlackBerry Dispatcher uses the device transport key of the BlackBerry device to decrypt and decompress the request, and sends the request to the BlackBerry Synchronization Service.

4.The BlackBerry Synchronization Service receives the changelist request, writes a synchronization request entry in the SynchRequest table of the BlackBerry Configuration Database, and sends the changed record to the BlackBerry Dispatcher.

5.The BlackBerry Dispatcher sends the changed record, in XML format, to the BlackBerry Messaging Agent.

If the file size of the picture exceeds 32 KB, the BlackBerry Messaging Agent rejects the synchronization request.

6.The BlackBerry Messaging Agent sends the changed record to the messaging server.

7.The messaging server updates the user’s personal contact list.

8.The BlackBerry Messaging Agent sends a delivery confirmation to the BlackBerry Dispatcher.

9.The BlackBerry Dispatcher sends the delivery confirmation to the BlackBerry Synchronization Service.

10.The BlackBerry Synchronization Service deletes the synchronization request entry from the SyncRequest table, writes an entry in the SyncRecordState table, and sends the delivery confirmation to the BlackBerry Dispatcher.

11.The BlackBerry Dispatcher encrypts the results using the device transport key of the BlackBerry device, compresses them, and sends them to the BlackBerry Router.

12.The BlackBerry Router sends the results to the wireless network over port 3101.

13.The wireless network verifies that the PIN belongs to a valid BlackBerry device and sends the delivery confirmation to the BlackBerry device.

If the BlackBerry device does not receive the delivery confirmation from the wireless network within 20 minutes, it sends the synchronization request to the wireless network again. If the BlackBerry device does not receive the delivery confirmation within 8 hours, it stops resending the synchronization request to the wireless network.
