Feature and Technical Overview

BlackBerry Enterprise Server process flows

User accounts that do not appear in the BlackBerry Configuration Database, or that are pending deletion, cannot receive the push content.

The central push server responds to the push application to acknowledge that it is processing the request, and sends the push content to the BlackBerry MDS Connection Service instances that have active, primary connections to the BlackBerry Enterprise Server instances.

3.The BlackBerry MDS Connection Service converts the content so that the user can view it on the BlackBerry device, and sends the content to the BlackBerry Dispatcher over port 3200.

4.The BlackBerry Dispatcher compresses the content, encrypts it using the device transport key of the BlackBerry device, and sends the encrypted content to the BlackBerry Router.

5.The BlackBerry Router sends the encrypted content to the wireless network over port 3101.

The wireless network verifies that the PIN belongs to a valid BlackBerry device that is registered with the wireless network, and sends the encrypted content to the BlackBerry device.

6.The BlackBerry device sends a delivery confirmation to the BlackBerry Router.

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.

7.The BlackBerry device decrypts and decompresses the content.

The BlackBerry Application detects the incoming content by listening on a port number that the application developer specified. For example, the BlackBerry Browser listens for push application connections on port 7874. The application displays the content on the BlackBerry device when the user runs the application.

Process flow: Installing a BlackBerry Java Application on a BlackBerry device over the wireless network

1.A developer creates a BlackBerry Java Application using the BlackBerry Java Development Environment or another Java authoring tool. The developer produces an application bundle.

The application bundle contains an .alx file that stores information about the attributes of the BlackBerry Java Application, including the author name, a description of the application, and copyright information.

2.In the BlackBerry Administration Service, you publish the application bundle to the application repository.
