FIELD: radio engineering, communication.
SUBSTANCE: parametrization of motion state of a wearable device, detection of presence or absence of the fallen state of the wearable device based on the value of the motion state parameter and transmission of information about the fall to the terminal to make the terminal issue an alarm signal, in case the portable device is in the fallen state, are performed. If this motion state parameter includes the speed and acceleration, and detection of presence or absence of the fallen state of the wearable device based on the value of the motion state parameter includes the definition of matching or mismatching of the motion state parameter value with the fallen state parameter, in which during the first time interval the acceleration is equal to gravity acceleration, and the speed is not equal to 0, and during the second time interval the acceleration and the speed are equal to 0 at the same time. And the first-time interval and the second-time interval are two consecutive time intervals. Then, the detection of the fallen state of the wearable device in case of matching of the motion state parameter with the fallen state parameter and detection of absence of the fallen state of the wearable device in case of mismatching of the motion state parameter value with the fallen state parameter.
EFFECT: possibility of expanding the information content of communication between the wearable device and the terminal by transmitting information about the fall.
