Abstract: It is an object to efficiently deliver a message to a user who subscribes to a plurality of telecommunications carriers.

Abstract: A server realizes reachability from a first user to a second user. The server (100, 200) includes a real-address-information receiving section (110) that receives real-address information, which is capable of contacting therethrough to the second user, from a second terminal (10) used by the second user; and a post-conversion-address-information generation section that generates post-conversion-address information, which the first user cannot specify, based on the real-address information received by the real-address-information receiving section.

Abstract: A buddy list manager stores a buddy list sent from a receiver terminal and manages the buddy list. A controller accepts an updating request and identifying information of a third party terminal from the third party terminal. When the controller accepts the updating request and the identifying information from the third party terminal, the controller determines whether the third party has an updating authority for updating the buddy list or not, using the identifying information. If the controller judges that the third party has an updating authority for updating the buddy list, then the controller permits the third party terminal to update the buddy list.

Abstract: To realize state estimation that corresponds with an actual situation by dynamically changing an abstract state calculation method. Upon receiving an abstract state monitoring request, an abstract state generation section 10 extracts a constituent element of an abstract state from the request, selects a rule for calculating an abstract state from the presence of the element, and generates a presence servicing client 20 that has a watcher for observing the element via a presence servicing section 40 and a presentity for issuing the presence of the abstract state to the presence service. Further, the rule for calculating an abstract state is changed in accordance with presence.

Abstract: When the status of a client X is changed to a status i, a group management unit generates a group agent Xi, corresponding to the status i and registers the generated group agent in the server S, and the presence issuing unit issues the status i and the identifier of the group agent Xi. Initially, a member management unit of the group agent xi manages the client X only. When other clients, such as clients B and C, that are observing the status of the client X send an instant message (IM) to the group agent Xi identified by the issued identifier, an IM delivery unit of the group agent Xi adds the clients B and C, which are IM senders, to the members managed by the member management unit and sends the IM to all members.

Abstract: It is required to make a subscriber terminal acquire guide information from many service enterprisers at appropriate timing while preventing leakage of private information such as a mail address capable of identifying an individual. By use of a center unit managing a customer based on a provisional ID and a customer introduction count, terminals of service enterprisers introduce customers by transferring provisional IDs therebetween according to the provisional ID, the customer introduction count, and the like issued from the center unit.

Abstract: A communication agent apparatus includes at least one mobile unit, a presence information inquiring unit, a handling method determination unit, and a handling method execution unit. The mobile unit transports a communication device. The presence information inquiring unit acquires presence information indicating the current situation of a called user. The handling method determination unit determines a handling method for communication made from a calling user to the called user on the basis of the acquired presence information. The handling method execution unit executes the determined handling method. When the handling method determination unit determines a handling method of delivering a communication device used for communication to the called user, the mobile unit delivers the communication device to the called user in accordance with a move command from the handling method execution unit.

Abstract: In a queue object control system in which store terminals, user terminals, and a queue control server are connected by way of a network so as to allow communication, the queue control server includes: store groups in which a plurality of stores are controlled as group turn-waiting queues; a store group control unit that receives usability states of the stores from store terminals and then determines whether any of the stores are available for use; a queue manipulation unit that receives requests from user terminals to register in the queues of store groups, registers the user terminals in the group turn-waiting queues, and, when any store of the store groups becomes available for use, selects user terminals that are registered in the group turn-waiting queues; and a usability notification unit that transmits notification of usability of stores that have become available for use to user terminals that have been selected.

Abstract: Disclosed is a system in which the status of a user is automatically inferred without relying on the user's manual input, and the so inferred status is displayed. The status of the user, making use of or holding a device, such as a mobile phone, is inferred from the use pattern of the device or from the information derived from sensors mounted to the device and the so inferred status of the user is issued as the presence information. On receipt of the information derived from the use pattern of the device or from sensors mounted to the device, the status calculation unit calculates the user's presence information based on calculating rules as held on a computation rule holding unit to issue the results as the presence information.
