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

7. 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.

8. 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: Requesting BlackBerry Browser content while access control is turned on for the

BlackBerry MDS Connection Service

1. A user requests Internet or intranet content from the organization's content server using the BlackBerry® Browser on

a BlackBerry device.

2. The BlackBerry device sends the request to the BlackBerry® Enterprise Server over port 3101.

3. The BlackBerry Dispatcher sends the request to the BlackBerry MDS Connection Service over port 3200.

4. The BlackBerry MDS Connection Service checks the BlackBerry Configuration Database to verify whether pull

authorization is turned on, and whether the user has permission to pull content from the specified content server.

If the user does not have permission to pull content from the specified content server, the BlackBerry MDS Connection

Service rejects the request and sends an error message to the BlackBerry device.

5. The BlackBerry MDS Connection Service creates an HTTP session for the user and sends the user’s authentication

credentials to the content server. If the user authenticates successfully, the BlackBerry MDS Connection Service sends

the HTTP request to the content server. If the user does not authenticate successfully, the BlackBerry Browser displays

an "HTTP 403 Error" message, and prompts the user to type the correct credentials.

6. The BlackBerry MDS Connection Service retrieves the content from the content server, converts it so that the user can

view it on the BlackBerry device, and sends it to the BlackBerry Dispatcher over port 3200.

7. The BlackBerry Dispatcher compresses the content, encrypts it with the master encryption key of the BlackBerry device,

and sends it to the BlackBerry Router.

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