  • Patent number: 9141092
    Abstract: The object is to appropriately control a frequency of performing the link process. A link device detects a movement of a user based on a result of a link process for linking an outlet and an electronic appliance used by the user. The link device also detects a scheduled event from a schedule of the user. In case an event is detected, the link device calculates a difference between a scheduled time when the event will occur and the current time, and increases a frequency of performing the link process as the calculated difference gets smaller. In case the movement detection unit does not detect a movement of the user by the scheduled event time, the link device increases the frequency of performing the link process larger than a current frequency being used.

  • Patent number: 8296447
    Abstract: The method is executed by a call control server that establishes a media session for sending and receiving media data between a calling terminal and a called terminal. The method includes exchanging messages with calling terminal and called terminal for establishing the media session, generating a session information necessary for establishing the media session based on the messages exchanged with the calling terminal and/or the called terminal, monitoring a media information included in the messages, the media information containing a definition specifying a way of exchanging the media data, determining, based on the monitoring result, whether the media session has been established, and transferring the session information to at least one other call control server different from the call control server if the media session has been established.

  • Patent number: 8200755
    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.

  • Publication number: 20090052651
    Abstract: A call control server establishes a connection between a first terminal agent and a second terminal agent, as an existing call. When a first real terminal device included in a first terminal group has accepted a transfer request, the call control server transmits existing-call terminal & media notification data to a second real terminal device included in a second terminal group. The second real terminal device clearly shows a user at the transfer destination the difference between media available in the second terminal group and the media involved in the existing call, and accepts from the user a designation of media to be employed in a transferred call. The call control server establishes a connection between a third real terminal device included in a third terminal group and a real terminal device included in the second terminal group, as the transferred call, in accordance with the designated media.

  • Publication number: 20070121490
    Abstract: Each of node servers provided in a cluster system connected to load balancers includes a storage portion for storing node-session information that associates a session ID and a node server in charge with each other and node life/death information, a node checking portion for, when receiving a message sent from any one of the load balancers, judging whether or not a node server in charge of the session of the message is functioning normally, and a node reassigning portion for updating the node-session information so that the node server in charge of the session is changed to an alternative node server and sending data indicating the alternative node server to a load balancer different from the load balancer that has sent the message. This allows the cluster system to process messages from a plurality of load balancers efficiently even when the node server is not functioning normally.

  • Patent number: 7139827
    Abstract: Method and system for reporting to a source user before communication begins communication means usable by both the source and a destination user. Operable communication means at each user's information terminal are stored in a list DB 2 in advance for each user. A selection device 1 receives a destination user designation from the source user who is requesting communication, and acquires the usable communication means of the destination user and the source user respectively from the list DB 2. There are also cases in which the selection device 1 acquires communication means usable by the source user from the selection device 1 or a user terminal 4. Next, the selection device 1 creates a candidate list describing communication means which both parties can use, and sends it from a WWW server, for example, to the source user terminal. Before communication begins, the candidate list is displayed at the source user terminal by a WWW browser, for example.
