Abstract: A software-defined radio equipment includes a hardware/module, implements radio equipment functions by downloading radio communication software that controls the hardware/module from an external source, and switches the radio communication software by using a distributed object. The software-defined radio equipment includes a first means that transmits, when a hardware to be used by the radio communication software is selected from the hardware/module, first predetermined information of the selected hardware, a second means that interrupts an execution of the radio communication software before selection when the selection is reselection and transmits second predetermined information of a selected hardware after the reselection, and a third means that transmits predetermined information of a hardware that is currently being selected. Further, if the selected hardware is the hardware that is currently being selected, an error is detected.

Abstract: According to an embodiment, it is possible to restrict usage of a web-based service error resolution service by multifunctional peripheral devices or the like. A multifunction device for such purposes includes a display unit with a display screen, a device unit configured to generate an error code when an error in the device unit occurs, and a processor. The processor configured to acquire the error code from the device unit and transmit an error notification including the error code to an external apparatus. The processor then receives a counted number of errors from the external apparatus, and then select an error resolution screen to be displayed on the display screen based on the received counted number of errors.

Abstract: A communication device used in a wireless system that includes plural communication devices and executes communication via at least one of the plural communication devices. The communication device includes: first means for judging whether communication control information can be compressed or not on the basis of a neighboring node search message among the plural communication devices and a response thereto, or the exchange of routing control information according to an ad hoc routing protocol; and second means for compressing the information volume of the communication control information by judging the contents of the communication control information and deleting or replacing redundant information or constantly fixed information if the communication control information can be compressed.

Abstract: In a communication device and a communication method, multiple pieces of QoS control information are stored in a routing information base, each piece of QoS control information, with a terminal wired to the communication device itself as a transmission source, defining a bandwidth control value and a priority degree that correspond to communication data specified by a combination of the transmission source and a destination. When communication data is inputted, a control unit selects QoS control information that matches a combination of the transmission source and the destination of the inputted communication data from among the stored multiple pieces of QoS control information and indicates a bandwidth to a bandwidth control unit on the basis of the selected QoS control information, indicates a priority degree to a DSCP marking unit, and performs wireless transmission.

Abstract: A communication device that is used for ad-hoc network communication or wireless mesh network communication includes a setting interface unit configured to set an IP address of a communication device corresponding to low-delay communication, and an ad-hoc routing control unit. When a request for low-delay communication is provided from the setting interface unit, the ad-hoc routing control unit determines a route matching the IP address of the communication device and determines whether the low-delay communication is possible. The ad-hoc routing control unit sets a control message transmission interval to the maximum interval when the low-delay communication is possible, and sets the control message transmission interval to the minimum interval when the low-delay communication is not possible.
