Status notifying method in communication system, status notifying server and communication system
A profile server group determines whether any request for status notification is received from the client. If there is a request for status notification, a handle name included in the request is obtained, and a status flag corresponding to the handle name is extracted from the hard disk. Next, the status flag is checked. If the on-line flag is set to “ON”, the user status is checked. If the user status is not “IN HIDING”, the user status is notified. On the other hand, when the on-line flag is set to “OFF”, the client with the handle name relating to the request notifies that it is offline.
