Abstract: In packet communication using TCP, a gateway device for relaying communication packets between a mobile node and a correspondent node, temporarily rewrites a parameter of the receive window size of the ACK packet of the TCP communication from the mobile node, to adjust the amount of communication packets transmitted from the correspondent node. Whit this configuration, it is possible to reduce the packet loss due to error control for the existing TCP communication with respect to the mobile node, without converting the mobile node and the correspondent node.

Abstract: A transmitting party adds reproduction time information to each transport packet to form an extended transport packet, encapsulates the extended transport packet, adds capsule counter information, and transmits the capsule. A receiving party has a storage means, and transmits a re-send request including the capsule count information to the transmitting party when a packet loss occurs. At the receiving party, the re-sent data received overwrites data in its original storage region. At reproduction, the receiving party decodes the data after compensating for jitter referring to reproduction time information. Accordingly, a packet loss or jitter is compensated for at both transmitting and receiving parties in a communications network such as the Internet so as to prevent the occurrence of a decoding error at the receiving party.

Abstract: Disclosed is a mobile communication system preventing the transmission of acknowledgements at a burst leading to a decrease in throughput caused by detecting the retransmission and the congestion of packets at the protocol of a transport layer. In a mobile communication system including a mobile terminal and gateway equipment for relaying a packet between a communication partner and the mobile terminal, if the gateway equipment receives the acknowledgement from the mobile terminal, the gateway equipment waits the transmission of the received acknowledgement to the communication partner until the estimated transmission time passes from the time at which the gateway equipment receives the previous acknowledgement from the mobile terminal.

Abstract: Broadcast points in a broadcaster's sole region are turned into package information by processing the contents transmitted from a broadcaster, and the package information is stored in the receiver common information region of a television broadcast receiver, and thereby, it becomes possible even for a communication browser that is an application of the television broadcast receiver to refer to and use the information of broadcast points. It is possible by using a communication browser to receive a service provided in a home page of a company other than the broadcasting company.

Abstract: It is provided a mobile communication system comprising base stations, call control servers and access gateways. The call control servers cause a mobile terminal accommodated in one of the control server to transmit the location registration request so that the mobile terminal accommodates in another control server according to a processing amount of control signals. The base station selects a second call control server into which the one of the mobile terminals is to be newly accommodated. The one of the call control server switches to a power-saving state after the mobile terminal is accommodated into the another call control server.

Abstract: A base station accommodation server can appropriately set a location registration area according to an installation location of a femto base station. The base station accommodation server is coupled to a location management server accommodating at least one first base station coupled to a first communication network, and accommodates at least one second base station connected to a second communication network. The base station is configured to determine a location management group identifier of the second base station based on a location management group identifier of the first base station that is present at a location from which the second base station can receive the location management group identifier broadcast by the first base station.

Abstract: A television broadcasting device 1 transmits a television signal onto which control data for controlling a browser function of a television receiver 2 has been multiplexed. A television screen generating section 20 generates a television screen based on the received television signal. A browser display instruction obtaining section 71, a URL obtaining section 72, and a display style information obtaining section 73 extract the control data multiplexed onto the television signal. When a browser display instruction 111 is received, a microcomputer 51 receives a content 102 corresponding to a URL 112 from a server 3, and generates a browser screen based thereon. A screen combining section 30 combines the browser screen with the television screen in accordance with display style information 113 received from the microcomputer 51. Thus, it is possible to display the browser screen in a combined form with the television screen in accordance with a display style designated by a broadcaster of the television signal.
