For example, if a wireless communication unit whose operation is stopped according to the state of the terminal is in use and the terminal stops the wireless communication unit, the operation of the wireless communication unit is not stopped. May be. Further, in consideration of power consumption and the like, after the use is finished, after the continuation of communication is interrupted, it may be stopped after a predetermined time has passed.
