5. The IBM Lotus Sametime server accepts the login request from the BlackBerry device, starts a dedicated TCP/IP connection
for the session, and listens for requests from the BlackBerry device for the session.
6. The BlackBerry Collaboration Service sends the acceptance, in encrypted and compressed format, through the BlackBerry
Dispatcher to the BlackBerry device, and creates a cache of the connectivity information to maintain the instant messaging
session.
Process flow: Starting an instant messaging session using the BlackBerry Client for Novell
GroupWise Messenger
1. A user logs in to a collaboration client on a BlackBerry® device.
2. The BlackBerry device compresses and encrypts the user ID and password and sends them through the BlackBerry Router
to the BlackBerry Dispatcher over port 3101.
3. The BlackBerry Dispatcher sends the request to the BlackBerry Collaboration Service over port 3200. If the BlackBerry
Collaboration Service is located on a remote computer, the request remains encrypted using a Research In Motion proprietary
protocol.
4. The BlackBerry Collaboration Service checks the BlackBerry Configuration Database to find out if the maximum number of
sessions has been reached, and performs one of the following actions:
• If the maximum number of sessions has been reached and a timeout limit is set, the BlackBerry Collaboration Service
logs out any instant messaging sessions on BlackBerry devices that are out of coverage, and any instant messaging
sessions that are no longer sending status messages to the BlackBerry Collaboration Service.
• If there are no idle sessions, the BlackBerry Configuration Database sends a "Server Busy" status message to the
BlackBerry device and rejects the login request.
• If the maximum number of sessions is not set and the number of sessions equals the total number that the Novell®
GroupWise® protocol supports, the BlackBerry device sends a "Failed (300)" status message to the BlackBerry device
and rejects the login request.
