中国移动数据业务运营支撑中心 BlackBerry Enterprise Server Message Flow Components that are utilized by BlackBerry Enterprise Server (BES) messaging: BlackBerry Handheld Wireless Carrier Network BlackBerry Infrastructure (RELAY) Internet Corporate Firewall Corporate Infrastructure (Exchange server, Domino server) BlackBerry Enterprise Server

中国移动数据业务运营支撑中心 BlackBerry Enterprise Server Message Flow User A creates an message on their BlackBerry and sends it. The message is encrypted using 3DES encryption and then compressed.

中国移动数据业务运营支撑中心 BlackBerry Enterprise Server Message Flow The message is then sent to the Carrier’s network wirelessly. The Carrier’s network recognizes the message as being BlackBerry traffic and forwards the message to RELAY.

中国移动数据业务运营支撑中心 BlackBerry Enterprise Server Message Flow RELAY receives the message and checks the message for the appropriate information (UID of the Desktop [CMIME] service book). This information provides Relay with the ability to route the message to the proper BlackBerry Enterprise Server.

中国移动数据业务运营支撑中心 BlackBerry Enterprise Server Message Flow RELAY then forwards the message via the internet, to the correct domain (sender’s mail infrastructure).

中国移动数据业务运营支撑中心 BlackBerry Enterprise Server Message Flow The corporate firewall needs to have port 3101 to have the BlackBerry Enterprise Server be able to redirect data. If port 3101 is open and the message is allowed to pass through, it is then forwarded to the BlackBerry Enterprise Server.

中国移动数据业务运营支撑中心 BlackBerry Enterprise Server Message Flow The BlackBerry Enterprise Server uncompress’ the message and decrypts it. It then takes the and forwards it to the mail server. The mail server places a copy of the message into User A’s Sent Items folder in their mailbox and then places the message in the outbox.

中国移动数据业务运营支撑中心 BlackBerry Enterprise Server Message Flow The mail server takes the (which is no longer 3DES encrypted) and forwards it to the firewall through port 25 as SMTP traffic.

中国移动数据业务运营支撑中心 BlackBerry Enterprise Server Message Flow The message travels through the internet as regular SMTP data and arrives at recipient B’s company firewall.

中国移动数据业务运营支撑中心 BlackBerry Enterprise Server Message Flow The firewall takes the and forwards it to the mail server.

中国移动数据业务运营支撑中心 BlackBerry Enterprise Server Message Flow The mail server places the new into the recipient’s mailbox. A new notification is sent to the BlackBerry Enterprise Server via MAPI (Microsoft Application Programming Interface). The BlackBerry Enterprise Server then retrieves a copy of the message.

中国移动数据业务运营支撑中心 BlackBerry Enterprise Server Message Flow Once the BlackBerry Enterprise Server has a copy of the message it checks for filters, in-cradle, and read status. If everything checks out, it encrypts the message using 3DES encryption and compress’ it. Next, it takes the message and forwards it to the firewall.

中国移动数据业务运营支撑中心 BlackBerry Enterprise Server Message Flow Using port 3101 the firewall sends the message via the internet to RELAY.

中国移动数据业务运营支撑中心 BlackBerry Enterprise Server Message Flow Once again, RELAY checks the message for the appropriate information (this time it is the recipient’s PIN number) and forwards the message to the proper Carrier’s wireless network.

中国移动数据业务运营支撑中心 BlackBerry Enterprise Server Message Flow The Carrier’s wireless network receives the message and forwards it to the appropriate BlackBerry Handheld.

中国移动数据业务运营支撑中心 BlackBerry Enterprise Server Message Flow The message arrives on the BlackBerry of user B, where it is uncompressed and decrypted. User B can now open and view the message.
