Publication number: 20080183866Abstract: A presence communication system capable of efficiently reducing the number of messages exchanged between presentities and watchers, thereby preventing lowering in communication quality. A presence server sets a group identifier as an identifier which is used to collectively look up a group of multiple pieces of presence information provided by presence information providers who have agreed to a use policy, aggregates and stores the presence information under the group identifier, and delivers the presence information requested to the group identifier. Each presentity provides the presence server with its presence information targeted to the group identifier. Each watcher requests the group identifier for the presence information provided by the presentities, and receives the presence information delivered from the presence server.Type: ApplicationFiled: March 26, 2008Publication date: July 31, 2008Applicant: FUJITSU LIMITEDInventors: Jun Maeda, Shinya Yamamura, Masaaki Takase

Publication number: 20070274489Abstract: An application server receives presence information with anonymous identification information of a presentity client. The application server transmits a message to an information distribution proxy. The message is addressed not to the identification information of the presentity client, but to the anonymous identification information of the presentity client. The information distribution proxy converts the anonymous identification information into real identification information, and forwards the message to the presentity client. Therefore, the application server does not know the real identification information of the presentity client. That is, there is no need for the application server to directly treat personal information, thereby producing the effect of eliminating the need for strict management of presence information.Type: ApplicationFiled: November 21, 2006Publication date: November 29, 2007Applicant: FUJITSU LIMITEDInventors: Shinya Yamamura, Jun Maeda

The originator transmits the collected target identifiers to the concentrator. The concentrator notifies the subscriber of the originator when the target identifiers transmitted from the originator includes the desired target identifier. The subscriber notifies the originator of a specification. The originator transmits a message to the subscriber in accordance with the specification, the message including the desired target identifier and other target identifiers received at about the same time as the desired target identifier.Type: ApplicationFiled: September 22, 2006Publication date: October 25, 2007Applicant: FUJITSU LIMITEDInventors: Shinya Yamamura, Shinichi Matsumoto, Masaaki Takase, Jun Maeda, Mitsuaki Kakemizu
