COMMUNICATION OF NOTIFICATIONS IN A WIRELESS BROADCAST NETWORK

摘要

A method for communicating notifications from a server to a device includes sending a primary message including data indicating notification status information (e.g. version number, update, system state change); and sending notification messages or flows apart from the primary message addressed to specific groups of devices (broadcast; composite address). Another method for obtaining notifications in a device from a server includes monitoring the primary message or flow including current notification status information, comparing the current notification information status information with a previous notification status information to determine if a change in notification status information has occurred, and obtaining addressed notification information- when a change in the notification status information has been determined. By using a primary message with abbreviated information to communicate whether changes to notification information have occurred, system resources can be conserved.
