Publication number: 20100235426Abstract: A server for providing presentity status is adapted to provide the latest status of a presentity to a watcher. The presentity and the watcher are respectively connected to a connection server through a network. The presentity belongs to at least one group, and the watcher also belongs to at least one group. The connection server can detect the latest status of the groups to which the presentity belongs. The server for providing presentity status automatically determines the provision of the status of the presentity to the watcher based on whether the respective authority values of the groups to which the presentity belongs and the respective authority values of the groups to which the watcher belongs satisfy a preset condition. When the preset condition is satisfied, the server for providing presentity status also sends the latest status of other presentities that belong to the same groups as the presentity and that are subscribed to by the watcher to the watcher.Type: ApplicationFiled: March 28, 2007Publication date: September 16, 2010Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventor: Yi-Wen Chang
