Abstract: A presence server stores a presence that is identified by presence IDs “a1” and “a2”, as the presence of a user “A”. User “A” can pass a card that they hold through a card reader at a timing of their choosing. The card reader reads in data from the card and transmits a renewal request to the presence server. The renewal request includes a renewer ID, an object ID, category information and the presence. When the presence server receives the renewal request, it specifies the presence ID “a1” of user “A” to be the presence that is to be renewed, based on the category information, and moreover, rewrites the presence of the presence ID “a1” to a presence “meeting room A” that is included in the renewal request. Thus, the card reader can renew the presence designated by the “category information”. As for the presence that is renewed, it is notified to a watcher of the presence “a1” from the presence server.

Abstract: An object of the present invention is to manage presence update by publishers that a presentity does not recognize. When the presence server 100 receives status information that indicates a status of presentity A from publisher B (#1), the presence server 100 stores it in the history table 9 and transmits a change notification to a watcher C (#3). Subsequently, the presence server 100 makes an inquiry to presentity A as to whether or not to allow an update by publisher B (#4). When it is allowed (#5, #6), publisher B is added in the allow list 8a of the allow list DB 8 (#7). Also, presence information is generated based on status information retrieved from the history table 9 (#8), is notified to the watcher C and is stored in the presence management DB 2b (#9, #10). When it is denied (#11), publisher B is added in the deny list 8b of the allow list DB 8 (#12). Also, status information received from publisher B is deleted from the history table 9.

Abstract: A reception-process manager of a call server writes, in a transfer-voice-data storage, voice data contained in a voice packet received from the transmitter terminal which has acquired the talk right. A transmission-process manager of the call server determines the next transmission interval of a voice packet for each receiver terminal on the basis of determination information received from the each receiver terminal. The transmission-process manager reads out the voice data in a size dependent on the determined transmission interval from the transfer-voice-data storage, generates voice packet containing the voice data for the each receiver terminal, and transmits the voice packet to the each receiver terminal. Thus, the voice-packet transmission interval can be changed for each receiver terminal without stopping voice-packet transmission.

Abstract: This invention is to enable transfer of a right to speak in an audio teleconference in view of usability. In this invention, a PoC server is introduced to achieve new functions, such as transfer of the right to speak, reservation to acquire the right to speak, and deprivation of the right to speak. The PoC server has a teleconference presence manager, a teleconference manager, and a teleconference audio communication manager. The right to speak is managed in a presence data storage of the teleconference presence manager. The teleconference presence manager directly manages the presence data storage, but the teleconference manager manages transfer of the right to speak.

Abstract: A communication control method of this invention includes: when a call-in request to a chat for another participant in a voice-based teleconference by a first participant of the voice-based teleconference is received, transmitting the call-in request to the chat to a terminal of another participant; and when a participation response to the chat by another participant is received, carrying out a presence management setting so as to enable the first participant and a participant replying the participation response to update and subscribe dialogue contents of the chat, which are managed as presence data delivered to subscribers when updated. Thus, by using the presence technique, it becomes possible that the conference is shifted from the voice-based teleconference to the character-based teleconference and both of the conferences coexist.

Abstract: It is an object of the present invention to relieve the burden on a watcher that uses a presence system to subscribe to the presence information of people and objects. For example, an attribute is a product name, and products A, B, C have the identical attribute value “DVDRecorder.” The server generates aggregate presence information, which includes the presence information of the products A, B, C (corresponds to the providers), and sends a notification of such to a watcher W (corresponds to the notification recipient) of the presence information of the products A, B, C. The watcher W collectively receives the presence information for every product name, and the watcher W is therefore relieved of the burden of classifying the presence information for every product name.

Abstract: A communication apparatus going to acquire transmission right accepts input of specifying a communication apparatus as a main target of output among other communication apparatuses, and then performs multi-address calling of output data to the other communication apparatuses. At executing output processing on the basis of the output data, the specified communication apparatus executes output processing such as image output and voice output for notifying the fact of being specified. In a system of PoC service or the like where one communication apparatus among a plurality of communication apparatuses acquires transmission right of transmitting voice data, and then performs multi-address calling of voice data to a plurality of the other communication apparatuses, it is avoided that a target person of speech who is a main target of transmission of voice data among all users operating the other communication apparatuses fails to listen to a speech.
