  • Publication number: 20080018430
    Abstract: A technology for detecting an RFID by a reader writer and transmitting harmonics for reading and writing the RFID timely without using an object detection sensor is provided. Using a nonlinearity of a rectifier or a demodulator in an IC chip of the RFID, a continuous wave or a modulated wave of two or more different frequencies is output from the reader writer. The RFID receives the continuous wave or the modulated wave of two or more different frequencies and the reader writer receives harmonics intermodulation generated by the rectifier or the demodulator in the IC chip. Therefore, the RFID can be detected without any special object detection sensor, and a modulated wave for reading or writing the RFID can be transmitted.

  • Publication number: 20070279191
    Abstract: A technique of reducing the interference wave occurred between a plurality of reader/writers in an environment in which a plurality of RFID systems are operating. An RFID system includes a plurality of reader/writers and a controller for controlling the plurality of reader/writers. Each reader/writer includes a body, antennas, and a distributor for selecting one antenna from the antennas. The controller selects an antenna having a positional relationship in which the interference wave is small from the antennas of each reader/writer, and giving a command for the antenna to the body of each reader/writer. Each reader/writer selects one antenna from the antennas based on the command from the controller and transmits a command to the RFID.

  • Patent number: 7174333
    Abstract: At a terminal where communication can take place via a network, ADF in which property information on data is stored is received, and based upon the communication systems (ordinary/SSL) which were used for receiving this ADF and the communication system which is used for receiving JAR in which the entity of the above mentioned data is stored, whether a communication pattern is allowable determined. JAR is received if the communication pattern is allowable, and JAR is not received if the communication pattern is not allowable for security reasons. In other words, data is obtained only when the communication pattern is allowable.

  • Patent number: 7096492
    Abstract: IP server W and gateway server GWS transmit data in HTML format in response to a request from mobile unit MS. At this stage, in the HTML data, the personal identification information request data string is added to a URL of the page corresponding to a service, which requires user authentication. As the HTML data is received by mobile unit MS, the user carries out an inputting operation to designate the URL while the image corresponding to the HTML is displayed on the liquid crystal display unit. Then, mobile unit MS reads out personal identification information from ROM, and transmits to mobile packet communication network MPN. IP server W carries out user authentication on the basis of personal identification information transmitted from mobile unit MS in this manner.

  • Publication number: 20060155803
    Abstract: A mobile phone stores a plurality of profile data, each including a portal URL. A user of the mobile phone selects for use data of a profile including the portal URL. When a Java-AP running on the mobile phone transmits to JAM an instruction for a communication, JAM stores the domain name of the portal URL included in the selected profile data as information about the inhibited destination of a communication performed by the Java-AP. JAM restricts communications performed by a Java-AP on the basis of the information about the inhibited destination stored by JAM. Thus, communications from a Java-AP running on the mobile phone to the server apparatus assigned with the domain name of the portal URL may be inhibited by selection of profile data including a portal URL.

  • Publication number: 20050102205
    Abstract: When an IP (Information Provider) server is accessed from a mobile station, a gateway server determines whether or not the IP server is to be IP billed (S101). If it is not to be IP billed, then user billing is applied. In this case, the gateway server sends a user management number of the mobile station and the number of exchanged packets to a billing system (S102). The billing system calculates a communication fee in accordance with the number of packets, and issues a bill to the user specified by the user management number (S103). On the other hand, if the accessed IP server is to be IP billed, then IP billing is applied. In this case, the gateway server sends the number of exchanged packets and the address of the accessed IP server to the billing system (S104). The billing system calculates a communication fee in accordance with the number of packets, and issues a bill to the IP (S105).
