BlackBerry Enterprise Server process flows

Messaging process flows

Process flow: Sending a message to a BlackBerry device

1. The IBM® Lotus Notes® router delivers a new message to a user’s IBM Lotus Notes mailbox.

2. The BlackBerry® Messaging Agent polls the user's mailbox and detects the message.

3. The BlackBerry Messaging Agent applies global filter rules to the messages in the user’s mailbox and filters the messages

that match the filter criteria.

If no global filter rules apply, the BlackBerry Messaging Agent applies filter rules that are user defined to the messages in

the user’s mailbox.

4. The BlackBerry Messaging Agent creates an entry in the BlackBerry state database.

The BlackBerry Messaging Agent uses this entry to track the delivery state and associate the Unid (applied to the message

in IBM Lotus Notes) with a randomly generated Reference ID (RefId) and tag. If the message is a meeting invitation or

calendar entry, the BlackBerry Messaging Agent appends the calendar information to the message.

The BlackBerry Messaging Agent uses the RefId to identify the message between the BlackBerry® Enterprise Server and

the BlackBerry device. The BlackBerry Messaging Agent uses the tag to identify the message between the BlackBerry

Enterprise Server and the wireless network.

5. The BlackBerry Messaging Agent sends the first 2 KB of the message to the BlackBerry Dispatcher.

6. The BlackBerry Dispatcher compresses the first 2 KB of the message, encrypts it using the master encryption key of the

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

The user state database shows the message status, which appears in the IBM Lotus Notes console and the IBM Lotus Notes

log.
