Status change notification method and system

摘要

In a status change notification system a notification is sent to a group of information terminals that conduct simultaneous communication by participating in a channel. The status change notification system includes a database DB and monitoring means 1. The DB is disposed outside the channel. The monitoring means 1 monitors an occurrence of a status change in the DB, and generates a notification of a status change when a status change occurs. At least one of the group of information terminals includes notifying means 3. The notifying means 3 receives a notification of status change from the monitoring means 1. The notifying means sends the notification to other of the group of information terminals to notify of the status change in a broadcasting manner. With such a status change notification system, users are notified of changes in real-time, thereby allowing users to conduct communication based on an assumption that all the users share the same information.
