A relay apparatus includes: a terminal position information updating part for updating position information of a wireless terminal and position information of a wired terminal stored in a terminal position information storing part, to position information of the wireless terminal and position information of the wired terminal obtained by a terminal position measuring device, based on IP addresses of the wireless terminal and the wired terminal; a terminal-to-terminal distance calculating part for calculating a distance between the wireless terminal and the wired terminal; a distance determining part for determining whether or not the calculated distance falls in a predetermined distance range represented by communication condition data stored in a communication condition data storing part; and a communication control part for controlling the communication between the wireless terminal and the wired terminal according to communication conditions represented by the communication condition data, when the calculated distance falls in the predetermined distance range.
摘要:
A mobile terminal, data communication method, and a computer program stored in a computer-readable medium for communicating management data in a more efficient way. A management data communication interface communicates management data regularly with a management server, while an application data communication interface communicates application data with an application server on a demand basis. A data collision detector detects a collision between the management data and application data. If a collision is detected, a priority resolver determines whether to prioritize application data over management data. The management data suppressor suspends the management data communication interface when the priority resolver has determined that application data should be prioritized over management data.
摘要:
A content management system which carries out a process for allowing content data for reproducing content to be used in a second communication terminal in place of a first communication terminal includes an authentication unit that authenticates that the second communication terminal is a takeover terminal which is a communication terminal which takes over rights to use the content from the first communication terminal and a rights information transmission unit that, in the event that it is authenticated that the second communication terminal is the takeover terminal, transmits second rights information which is necessary in order to use the content data, and which is valid only for the second communication terminal, to the second communication terminal.
摘要:
A tag access control system capable of setting an appropriate parameter for controlling a reader/writer can be provided. The tag access control system includes a control portion that controls data communication between an IC tag and a reader/writer by sending a command to the reader/writer in accordance with a parameter and receiving an execution result; and a parameter adjustment portion that adjusts the parameter to an appropriate value. The parameter adjustment portion includes a parameter change portion that changes the parameter a plurality of times, a result storage portion that records execution results of commands based on a plurality of parameters that are changed and a calculation portion that calculates an appropriate parameter based on the execution results stored in the result storage portion.
摘要:
A computer-readable recording medium storing a data communication program capable of transmitting desired data quickly. The mobile terminal (computer) has the following functions: A data accumulating section accumulates accumulation data to be uploaded to a server 7. A transmission data-generating section generates transmission data that is to be transmitted to the server for making the inquiry and has the accumulation data added thereto. A determination section determines whether or not the mobile terminal is in a state in which the transmission data can be transmitted to the server. A communication scheduler permits a data communication section to transmit the transmission data to the server based on the result of determination of the determination section. The data communication section transmits the transmission data to the server in response to permission of the communication scheduler.
