METHOD AND SYSTEM FOR TRANSMISSION OF NOTIFICATION MESSAGE IN A MOBILE BROADCAST SYSTEM

摘要

A method for transmitting a notification message in a portable broadcasting system and a system according to the same are provided to support a bidirectional channel. If a notification event is received, a notification generation function(203) writes a notification message corresponding to the notification event. The notification generation function(203) determines a path of the notification message. When the path of the notification message is a bidirectional channel, the notification generation function(203) transmits a transmission request message including a target address of a corresponding terminal(119) to an NDAF(Notification Distribution/Adaptation Function)(202). The NDAF(202) receives the transmission request message, confirms the transmission path and the target address, and transmits the notification message to the terminal(119) through the corresponding target address.
