Multi-User Multimedia Messaging Services

摘要

Methods, devices, and computer programs for efficient reporting of a transmission state of a multimedia message addressed to recipient user devices. A multimedia message is sent from an originator user device to an originator server and further to one or more recipient servers with which the recipient user devices are associated. The recipient servers send the multimedia message to the addressed recipient user devices associated with the recipient server and receive status messages, each status message including an indication of an individual message transmission state of the multimedia message at one of the recipient user devices. The recipient servers aggregate the indications according to at least two message transmission state types into a report representing the transmission state of the multimedia message, and send the report to the originator server.
