7. The BlackBerry Router sends the encrypted data to the wireless network over port 3101, or over port 4101 if the BlackBerry

device is a Wi-Fi® enabled BlackBerry device that is connected to the enterprise Wi-Fi network.

8. The wireless network verifies that the PIN belongs to a valid BlackBerry device that is registered with the wireless network,

and sends the message data to the BlackBerry device.

9. The BlackBerry device sends a delivery confirmation to the BlackBerry Dispatcher. The BlackBerry Dispatcher sends the

delivery confirmation to the BlackBerry Messaging Agent.

The BlackBerry Messaging Agent writes the message delivery state to the BlackBerry state database. If the BlackBerry

Messaging Agent does not receive a delivery confirmation within four hours, it sends the message to the wireless network

again.

The delivery confirmation verifies that the wireless network delivered the message to the BlackBerry device, but it does not

verify that the user received or opened the message.

10. The BlackBerry device decrypts and decompresses the message so that the user can view it, and notifies the user that the

message has arrived.

Process flow: Sending a message from a BlackBerry device

This process flow applies to new messages, reconciled messages (messages that a user moved, deleted, or marked as read or

unread), and wireless calendar entries.

1. A user sends a message from a BlackBerry® device.

The BlackBerry device assigns a RefId to the message. If the message is a meeting invitation or calendar entry, the BlackBerry

device appends the calendar information to the message. The BlackBerry device compresses and encrypts the message,

and sends the message to the wireless network over port 3101, or over port 4101 if the BlackBerry device is a Wi-Fi® enabled

BlackBerry device that is connected to the enterprise Wi-Fi network.

2. The wireless network sends the message to the BlackBerry® Enterprise Server.

The BlackBerry Enterprise Server accepts only encrypted messages from the BlackBerry device.
