Abstract:
PROBLEM TO BE SOLVED: To provide a media reproduction apparatus that enables a display apparatus corresponding to a wired LAN to work as a wireless one without separately providing a bridge apparatus that carries out conversion between wired LAN and wireless LAN. SOLUTION: A media reproduction apparatus 100 has a media reproduction unit 106 that can reproduce media data received by any one of a wireless LAN interface 101 and a wired LAN interface 102, and a protocol converter 105 that carries out protocol conversion between the wireless LAN interface 101 and the wired LAN interface 102. When the wireless LAN interface 101 has a connection with a wireless LAN access point and the wired LAN interface 102 has a connection with a television corresponding to the wired LAN, the protocol converter 105 carries out protocol conversion of data transmitted or received between the wireless LAN access point and the television corresponding to the wired LAN, and then relays the data.

Abstract:
A mapping operation maps identified bytes of a transport overhead of a data stream to other unused areas of the overhead. A de-mapping operation maps the bytes mapped by the mapping operation back to the locations from which the bytes were moved. A passing operation is used to handle data stream transitions in which multiple tributaries are multiplexed into or out of a single connecting data stream.

PROBLEM TO BE SOLVED: To solve the following problem: unauthorized use of a radio terminal similar to an existing public mobile communication network is not prevented in a communication system using a femto cell base station. SOLUTION: The femto cell base station includes: a generating means for generating, on a predetermined occasion, a SIP (Session Initiation Protocol) message including both a terminal ID of the radio terminal and a check request of the terminal ID; and a first transmitting means for transmitting the SIP message, generated by the generating means, to a host apparatus in the communication system.

Abstract:
PROBLEM TO BE SOLVED: To provide a communication system which can achieve Short Message Service (SMS) provided in an existing 3G network in the communication system to which a femtocell base station is introduced.SOLUTION: When receiving information relating to the SMS from UE (User Equipment), the femtocell base station (FAP) converts it into an SIP (Session Initiation Protocol) message including the received information relating to the SMS, and transmits the converted SIP message to a core network side. Also, when receiving the SIP message including the information relating to the SMS from the core network side, it converts the information relating to the SMS included in the received SIP message into a message that can be recognized by the UE, and transmits the converted information relating to the SMS to the UE.
Abstract:
A communication device of the present invention includes a physical layer for performing close-range one-to-one communication with a device of a communication counterpart by electric field coupling or magnetic field coupling; one or a plurality of PCL Emulations for converting a protocol of a higher level application to a protocol for communicating at the physical layer; and a PCL common for performing negotiation with the device of the communication counterpart without the higher level application started after the connection with the communication counterpart is established or at the same time as the connection establishment to select one PCL Emulation.
Abstract:
The cellular phone 1a sends a printing request to the PC 2 using a protocol that is allowed to connect bi-directionally between an internal network and an external network at the firewalls 5a and 5b, the PC 2 uploads a printing job to the file server 4 using a protocol that is allowed to connect only from an internal network to an external network at the firewall 5a, and the printer 3a downloads the printing job to print from the file server 4 using a protocol that is allowed to connect only from an internal network to an external network at the firewall 5b. The present invention enables one to form images of files stored on an image forming data transmission device on a first intranet on an image forming device on a second intranet using a portable terminal and a file server on an external network.
