Feature and Technical Overview | BlackBerry Enterprise Server process flows |
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 devices that are out of coverage, and any instant messaging sessions that are no longer sending status messages to the BlackBerry Collaboration Service.
•If no idle sessions exist, the BlackBerry Collaboration Service sends a Server Busy status message to the 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 HTTP persistent connection supports, the BlackBerry Collaboration Service sends a Failed status message to the device and rejects the login request.
The BlackBerry Collaboration Service checks the BlackBerry Configuration Database to verify that the user has permission to use the collaboration client, and tries to authenticate the user using Integrated Windows Authentication. If the authentication is not successful, the BlackBerry Collaboration Service tries a
The BlackBerry Collaboration Service opens the connection using HTTPS over port 443. You can also configure the connection to use HTTP, the transport protocol that the AJAX service uses, or a custom port number.
5.The Microsoft Office Communicator Web Access server formats the request using a Microsoft API and sends the request to the Microsoft Office Live Communications Server over an MTLS connection.
6.The Microsoft Office Live Communications Server accepts the request, processes the login information, and sends the acceptance to the Microsoft Office Communicator Web Access server.
7.The Microsoft Office Communicator Web Access server sends the acceptance to the BlackBerry Collaboration Service.
8.The BlackBerry Collaboration Service sends the acceptance message, in encrypted and compressed format, through the BlackBerry Dispatcher to the device, and creates a cache of the connectivity information to maintain the instant messaging session.
The BlackBerry Collaboration Service receives events that the server initiates from the Microsoft Office Communicator Web Access server using an HTTP GET or HTTPS GET request, and sends the events to the collaboration client over the session. The BlackBerry Collaboration Service sends events that the BlackBerry device initiates to the Microsoft Office Communicator Web Access server using an HTTP POST or HTTPS POST request.
