The communication apparatus includes a message receiving section that receives a message which is transmitted from the other communication apparatus, and the message in which reconnection control information related to an operation after an end of the session is described in the basic method or the reply, and a first controlling section that performs a reconnection control based on the reconnection control information contained in the message.
Abstract:
Disclosed is a path setting device capable of setting a distribution path of packets more speedily, when the originator of information is switched. The terminal (100) as the device sets the distribution path of the packets to a communication network which distributes the information from an unspecified terminal to a large number of terminals by transferring the packets. The terminal (100) comprises: an expanded distribution tree calculation unit (140) which calculates the distribution path in accordance with the position, on the communication network, of an origination candidate terminal which is a terminal capable of originating information; and a table setting server unit (150) which sets the calculated distribution path to the communication network. The distribution path calculated by the expanded distribution tree calculation unit (140) comprises: a distribution tree to transfer the packets from a root terminal to the large number of terminals; and a connection tree path to transfer the packets from the origination candidate terminal to the root terminal.
Abstract:
A conferencing apparatus that is adapted to facilitate a video conference includes a first address information acquisition unit that acquires address information of a first processing terminal device which is connected to a first conferencing apparatus via a first local area network, a first address information notification unit that notifies both the address information of the first conferencing apparatus and the address information of the first processing terminal device to a second conferencing apparatus currently communicating with the first conferencing apparatus, and a first address information reception unit that receives at least address information of the second conferencing apparatus transmitted from the second conferencing apparatus. When the first conferencing apparatus receives a request message of start of sharing from the first processing terminal device, the first address information acquisition unit of the first conferencing apparatus acquires address information, and the first address information notification unit performs notification of the acquired address information. Therefore, conference materials can be output on display devices of the respective processing terminal devices of the participants in the video conference without requiring high level setting of the network. In addition, other participants can carry out interactive operations with respect to a material which is presented by a participant.
Abstract:
A connection device that does not require complicated operation by a user an interconnects a single-display conference terminal and the multi-display conference terminal includes an address holding unit (103) configured which holds address information indicating an address of the single-display conference terminal and address information indicating an address of the connection device, a media information obtaining unit (105) which obtains information related to media that each of the single-display conference terminals can process, and holds the entire obtained information as first media information, a session control unit (104) which establishes a session with the multi-display conference terminal using the address information of the connection device and the first media information obtained by the media information obtaining unit (105), while obtaining second media information related to media that the multi-display conference terminal can process, and a media control unit (106) which establishes a session with the single-display conference terminals using the second media information obtained by the session control unit (104) and controls the single-display conference terminals to transmit and receive data.
Abstract:
A connection device according to an aspect of the present invention is a server (104) which establishes a connection among a terminal (101), a terminal (102), and a terminal (103) for a multipoint conference in which media data is directly transmitted and received among the terminals (101 to 103), the connection device includes a caller information obtaining unit (202) and a callee information obtaining unit (203) which obtains media information of the terminals, a holding unit (204) which transmits, to the terminal (101), a first message for preventing the terminal (101) from starting a transmission of the media data to the terminal (102) and the terminal (103), when the media information of the terminal (102) and the terminal (103) is not obtained, and a communication starting unit (205) which transmits a second message (i) including the media information of the terminal (102) and (ii) for causing the terminal (101) to start transmitting the media data to the terminal (102), when the media information of the terminal (102) is obtained after the first message is transmitted.

Abstract:
An application service delivery method capable of making use of an existing SIP server function and easily carrying out authentication and billing. When a user who operates a client requests a service delivered by an application server, the present method establishes an SIP session between a client and application server using a standard SIP procedure via a relay server, and provides a direct service between the client and application server after establishment of the SIP session. The relay server carries out user authentication in the stage of establishment of the SIP session, which eliminates the necessity for the authentication function of the application server and makes it possible to easily construct the application server.
