  • Patent number: 6865385
    Abstract: To enable reporting user status more precisely and over a wide range, the present invention includes an information terminal PC1 having a generating device, a mobile terminal M having a transmitting device, and an information terminal PC2 having a receiving device. The information terminal PC1 and the mobile terminal M can communicate directly wirelessly or through a wire. The mobile terminal M and the information terminal PC2 can communicate in real time via status notification devices. The information terminal PC1 reports the user status it detected to a mobile terminal M that is in a communicable area. The mobile terminal M sends the user status to the information terminal PC2 via the status notification device if the user status it received is the status of the user that has been stored therein in advance.

  • Publication number: 20040044738
    Abstract: Change of an identifier is reported without causing trouble to user agents. When a user agent A changes an identifier “A1” of a client 2a that he/she operates, notification recipients of a new identifier “A2” are automatically decided and the notification is carried out accordingly. It is desired that the recipients of the new identifier be preferably determined so as not to include unnecessary notification recipients, taking their relationship with the user agent A into consideration. For this reason, the maximum range of the notification recipients of the identifier is limited to be within watchers of the user agent A. The watchers are the notification recipients of user agent A's presence information, and therefore, it is assumed that there is little need for the identifier to be told to others who are not the watchers.

  • Publication number: 20040003037
    Abstract: In a presence system in which one user users a plurality of terminals, dynamically changing buddy lists are synchronized between the terminals. A presence notification message is sent to all the terminals of the user. The timing of sending includes, for example, when the presence information of a buddy is updated, when a new buddy is set, when display attribute information is updated, when a buddy is cancelled, and when a presence notification of unknown presentity is made. Thus, when one user uses a plurality of terminals in the presence system, dynamically changing buddy lists can be synchronized between the terminals. In addition, the display formats of the buddy lists do not differ from one terminal to another, and the same display format is attained.

  • Patent number: 6671508
    Abstract: A mobile communication terminal having a phonebook with information corresponding to alternative communication services. The information can be entered remotely from another mobile communication terminal. When a sender selects a recipient and a service from the phonebook, the mobile phone displays the information with the phonebook. The sender selects the most convenient and available communication service for the selected recipient. In an alternative embodiment, a mobile communication network maintains communication statuses of a plurality of mobile communication terminals in a status database. Upon detection of a status change of one of the mobile communication terminals, a notifying portion notifies the other mobile communication terminals of the status change.

  • Publication number: 20030229687
    Abstract: Restricting the setting of presence information by presentities. Among other forms of presence information, restricted presence information that a user agent cannot determine him/herself is established. If among other forms of presence information “game score” is for example made restricted presence information, only user agent B, being a game administrator, would be able to determine the “game score.” When user agent A's game score is updated by user agent B, the game score is reported to user agent A's Watcher C.

  • Publication number: 20030014487
    Abstract: An “introducing” information generating part of an introducing part generates “introducing” information based on data in a buddy list storing part, in accordance with an instruction of a user of the introduction origin system, and notifies an introduction destination system of the “introducing” information through an “introducing” information notifying part. A buddy list registering part of the introduction system registers a user to a buddy list based on the “introducing” information and generates registration information. A registration information notifying part notifies the introduction target system of the registration information. Furthermore, the registration information notifying part notifies the introduction target system of “introduced” information representing that introduction is received. An “introduced” recognizing part of the introduction target system recognizes an introduction relationship.
