PROBLEM TO BE SOLVED: To provide a technique of changing the structure of data to be stored in a packet signal so that the structure of the data is adapted to each of a normal time and an emergency time.SOLUTION: An RF unit 52 and a modulating and demodulating unit 54 receive a packet signal from another radio device and informs the packet signal. An application manager 78 processes the received packet signal, and generates a packet signal to be informed. First type data contained in the received packet signal and second type data for which the present radio device serves as a transmission source can be stored in the generated packet signal. The application manager 78 more preferentially stores the first type data in the packet signal when emergency is detected as compared with a case where emergency is not detected. |
