摘要:
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.

A data output apparatus checks data accumulated state in the accumulating unit at a preset check interval, and changes at least one setting among an initial accumulation amount to be used as a basis for starting to output the data accumulated in the accumulating unit, an upper accumulation limit amount to be used as a basis for discarding accumulated data, and a check interval, according to a discarded state of the data based on check results. Therefore, in the data output apparatus such as an IP telephony terminal apparatus, it is possible to prevent sound interruption and limit a lowering of communication quality.

A communication control apparatus comprises a terminal control part that generates available-terminal information representing a communication terminal belonging to a group of available-terminals and also generates call-status information representing one of the communication terminals having calls and also representing the media of the communication terminals; a terminal/media selecting part that, upon detection of an event occurrence, if the call-status information matches terminal/media information of a terminal/media information storing part and further if changed-terminal/media information of the terminal/media information storing part is included in the available-terminal information, then determines the communication terminal represented by the changed-terminal/media information as a communication terminal to be incorporated into the calls of the media of the communication terminals; and a session control part that establishes a call of the medium of the determined communication terminal between the determined communication terminal and a communication terminal of another user.

A data output apparatus judges whether or not sound data that has not yet been outputted has been accumulated. When a judgment is made that there is no accumulation of sound data that has not yet been outputted, the data output apparatus reads already-outputted sound data that was outputted previously and saved, and reproduces (outputs) sound based on the read sound data. Since it is possible to reduce occurrence of abnormality such as sound interruption in the data output apparatus such as an IP telephony terminal apparatus, a lowering of communication quality such as voice quality can be prevented.

The input unit stores data input by the user in the data storage. The status determiner determines reception status of the screen data to be one of three statuses of “abnormal”, “normal”, and “recovery” from “abnormal” to “normal” on the basis of frame losses. In a case of the “abnormal” status, a transmission controller does not read the input data stored in the data storage. In a case of the “normal” status, the transmission controller reads the input data stored in the data storage, transmits the input data via the transmitter, and deletes the input data stored in the data storage. In a case of the “recovery” status, the transmission confirmer instructs the output unit to output the input data stored in the data storage to ask the user whether to transmit the input data to the server.

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.
摘要:
The text messaging system consists of mobile terminal (5) connected to mobile communication network (4), information terminal (3) connected to computer network (2), and server (1) connected to the mobile communication network and the computer network. The information terminal (3) has status detection means (22), (23), and (24), and detects an operational status including at least the connection status of the computer network and notifies the server (1) of it. The server (1) has status administration means (8) and (9) and decision means (10). The status administration means (8) and (9) retain the operational status of the information terminal (3) notified from status detection means (24) for each user. The decision means (10) determines a send mode according to the operational status of the information terminal such as whether to send a text message to an information terminal or to send a text message with a network application.
摘要:
A communication support system is connected with a network enabling communication among user terminals and is capable of accessing a user information recording portion in which shared information concerning users and access information showing users who accessed the shared information are recorded. The communication support system includes: a user identification portion that acquires a communication start request from a user terminal and identifies an originator and a receiver; a retrieval portion that retrieves shared information concerning the receiver that the originator has not accessed from data recorded in the user information recording portion; and a control portion that, based on a result of the retrieval by the retrieval portion, controls the communication. Thereby, the communication support system can control whether or not to start the communication based on the presence or not of information about the receiver that the originator should confirm.
摘要:
A connection apparatus is employed which is connected to a repeating apparatus for providing the PoC for first communication apparatuses having a PoC function. Call connection is established between the connection apparatus and second communication apparatus not having the PoC function. In the connection apparatus, recorded is apparatus information for identifying each second communication apparatus. The connection apparatus has the function of acting as a proxy of the second communication apparatus identified by the apparatus information. This function consists of the function of performing half duplex communication with the repeating apparatus; the function of transmitting output data received from the second communication apparatus, to the repeating apparatus when the second communication apparatus has acquired transmission right; and the function of transmitting received output data to the second communication apparatus when the output data is received from the repeating apparatus.
摘要:
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.
