| 20090154344 | WIRELESS COMMUNICATION SYSTEM, COMMUNICATION TERMINAL AND STORAGE MEDIUM STORING WIRELESS COMMUNICATION PROGRAM - A wireless communication system comprises a control terminal and a controlled terminal, the control terminal comprises a control information transmitter transmitting the control information, a response information receptor receiving response information, a selector selecting the controlled terminal to become a new control terminal, a request information transmitter transmitting request information, and a controlled terminal transition device stopping the control terminal being the control terminal and transfers to become the controlled terminal, and the controlled terminal that operates based on the control information transmitted a control information receptor receiving the control information, a response information transmitter transmitting the response information, an operation execution device performing an operation prescribed by the control information, a request information receptor receiving the request information, an acceptance information transmitter transmitting the acceptance information, and a control terminal transition device stopping the controlled terminal being the controlled terminal and transfers to become the control terminal. | 06-18-2009 |
| 20090170546 | WIRELESS COMMUNICATION SYSTEM, COMMUNICATION TERMINAL AND COMPUTER-READABLE STORAGE MEDIUM STORING WIRELESS COMMUNICATION CONTROL PROGRAM - A wireless communication system comprised of a control terminal and controlled terminals which belong to one or a plurality of groups, the control information being transmitted in group units, the control terminal includes a transmission order determination device determining an order of transmission destination groups to which the control information is transmitted, and a control information transmission device transmitting the control information in the order determined by the transmission order determination device, and the controlled terminals each includes a control information receiving device receiving the control information, a communication information storage device storing communication information, a transition determination device determining whether the controlled terminal becomes a next control terminal that is a control terminal next to a current control terminal, and a next control terminal transition device transferring the controlled terminal itself to become the next control terminal according to the determination by the transition determination device. | 07-02-2009 |
| 20100229104 | Teleconferencing apparatus, Teleconferencing system, method of controlling Teleconferencing apparatus, and computer-readable medium storing control program for controlling teleconferencing apparatus - A teleconferencing apparatus for a teleconference to be performed between a plurality of terminal apparatus including a shared display area and an individual display area, the teleconferencing apparatus includes a browsing page information storage control device that causes a browsing page information storage device to store, identification information for identifying the terminal apparatus having sent the page information and the received page information, a browsing time information storage device that stores, as browsing time information, the page information of the display data displayed in the individual display area and a display time indicating a time in which a page specified with the page information is displayed in the individual display area unlike a page in the shared display area, a sending device that sends page information of the browsing time information, to the terminal apparatus. | 09-09-2010 |
| 20110075668 | COMMUNICATION SYSTEM, TERMINAL DEVICE, AND COMMUNICATION METHOD - A communication system for performing communication based on the Real-time Transport Protocol/RTP Control Protocol (RTP/RTCP) comprises a communication control device, a first NAT device and a second NAT device, a caller terminal device, and a callee terminal device. The caller terminal device transmits a first packet to the communication control device, receives a second packet that contains a second port number that is stored in the second NAT device, determines whether the second port number is one of an odd number and an even number; and transmits, in a case where it has been determined that the second port number is an odd number, an RTP packet to a port number that is computed by adding 2n−1 to the second port number, then transmits an RTCP packet to a port number that is computed by adding 2n to the second port number. | 03-31-2011 |
| 20110078315 | COMMUNICATION SYSTEM, COMMUNICATION CONTROL DEVICE AND COMMUNICATION CONTROL METHOD - A communication system comprises a NAT device, a terminal device, and a communication control device. The communication control device comprises a first storage unit that stores a NAT address, a first receiving unit that receives a type request signal, a first determination unit that determines whether the NAT address matching a source IP address of the type request signal is stored in the first storage unit, and a first transmitting unit that transmits the type information associated with the NAT address matching the source IP address to the terminal device. The terminal device comprises a second transmitting unit that transmits the type request signal, a second receiving unit that receives the type information, and a communication control unit that performs Peer to Peer communication with another terminal device that is subordinate to another NAT device by performing communication using a method to establish communication based on the received type information. | 03-31-2011 |
| 20120002570 | Coordinating and Establishing Communication Networks Between Communication Devices - In a multipoint mesh network, communications for establishing the network between multiple communication terminals may be coordinated such that connection request signals are not transmitted from both terminals in a pair of terminals to each other. In one example, a multipoint connection start terminal may be configured to request connections with each of the communication terminals participating in the mesh network. The multipoint connection start terminal may then receive a connection permission signal from each of the terminals to which a request signal was sent. The multipoint connection start terminal may subsequently generate terminal designation information specifying which terminals are to request connections with which other terminals so as to avoid communication overlap. This terminal designation information may then be transmitted to each of the other communication terminals participating in the mesh network. Additionally or alternatively, the terminal designation information may include authentication information for authenticating the connection request and/or permissions. | 01-05-2012 |
