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: 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: A software radio device according to the present invention has plural executing devices constituting the software radio device as a whole, each of the executing devices executing application software by a board computer. In the software radio device, first application software executed by at least one first executing device of the plural executing devices makes the first executing device execute an instructing step of instructing the executing device to execute a determination step, and upon reception of the instruction, second application software other than the first application software executed in the executing device makes the executing device execute the steps of determining, on the basis of an operation environment of predetermined application software and environmental information of the board computer whether the predetermined application software is executable in the executing device, and loading into the executing device the application software which is determined to be executable.

Abstract: A second software radio set requests a first software radio set to send a profile analysis result of the second software radio set. If it is stored in the first software radio set, the second software radio set composes an update application delivered from an update server using the profile analysis result received. If not, the second software radio set itself performs a profile analysis and composes the update application using a result of the profile analysis. The second software radio set sends the profile analysis result to the first software radio set and has it stored in the first software radio set.
