9. The BlackBerry device sends a delivery confirmation to the BlackBerry Router, and decrypts and decompresses the
content so that the user can view it in the BlackBerry Browser.
If the BlackBerry MDS Connection Service does not receive a delivery confirmation within the flow control timeout limit,
it sends a message to the wireless network to delete the pending content.
Process flow: Pushing application content to a BlackBerry device
1. A push application on an application server or content server behind the organization's firewall sends an HTTP POST
request to a central push server over the listen port for the content server. The default port number is 8080.
One or more instances of the BlackBerry® MDS Connection Service in a BlackBerry Domain can be defined as a central
push server. A push application specifies the BlackBerry® Enterprise Server host name and the connection port number
that the BlackBerry MDS Connection Service listens on.
2. The central push server checks the BlackBerry Configuration Database for the following information about the intended
recipients of the application content: the PINs that are associated with the users, whether the users' PINs are enabled
for the BlackBerry MDS Connection Service, and the active BlackBerry Enterprise Server instances that the users are
located on.
Users who do not appear in the BlackBerry Configuration Database, or whose accounts are pending deletion, cannot
receive the push content.
3. The central push server responds to the push application to acknowledge that it is processing the request, and sends
the push content to the active instances of the BlackBerry MDS Connection Service that are associated with the active
instances of the BlackBerry Enterprise Server.
4. The BlackBerry MDS Connection Service converts the content so that it can be viewed on the user's BlackBerry device,
and sends the content to the BlackBerry Dispatcher over port 3200.
5. The BlackBerry Dispatcher compresses the content, encrypts it with the master encryption key of the BlackBerry device,
and sends it to the BlackBerry Router.
6. The BlackBerry Router sends the encrypted content to the wireless network over port 3101, which verifies that the PIN
belongs to a valid BlackBerry device that is registered with the wireless network.
7. The wireless network sends the encrypted content to the BlackBerry device.
