Portable wireless terminal and wireless communication method

摘要

It is an aim of the present invention to easily transmit a user's critical state with certainty by an intuitive operation which is not difficult to operate while being able to avoid incorrect activations. A portable wireless terminal (110) of the present invention includes a vibration detection part (226) which detects a vibration of the portable wireless terminal and obtains a vibration value, a vibration amount judgment part (230) which judges whether a vibration amount calculated based on the detected vibration value and the time during which the vibration value exceeds a predetermined vibration value has reached a predetermined threshold, and a transmission part (232) which transmits to the contact destination terminal registered in the portable wireless terminal in the case where the vibration amount is judged to have reached the predetermined threshold.
