Abstract
A system and method for delivery confirmation of a short message comprising sending the short message to an recipient communication device, determining that an instant message delivery notification (IMDN) is not received, and indicating delivery failure of the short message to the mobile station. In another aspect, if a 202 Accepted message is received, the IM server is subscribed to. Alternatively when a message indicating that an recipient communication device is reachable is received, the service center sends the short message to the communication device. In another alternative, if a recipient absence notification is received the short message is buffered in a service center until the service center receives notification that the recipient communication device is present. Upon receipt of the notification, the service center retransmits the short message, and a successful delivery report is sent when the short message is received by the recipient communication device.
