Means for identifying stop periods of a device in a location

A method for determining a stop period of a mobile device in geographical locations, according to geolocation data related to said mobile device, and for triggering an action accordingly, the method being executed by said mobile device and comprising:

• during a first step, determining a predicted position of the mobile device, according to a new filtered position obtained using a discrete-time Kalman Filter with the geolocation data and a first position related to the mobile device, the first position being:
• either a current position of the mobile device if it is possible to obtain said current position from the geolocation data;
• or,
• if the current position of the mobile device is not available from the geolocation data, an artificial position of the mobile device corresponding to a last received new position of the mobile device available from the geolocation data;
• during a second step,
• determining a normalized prediction error according to the difference between the new predicted position and the first position;
• if the normalized prediction error is smaller than a prediction error threshold, generating a stop message to indicate that the stop period is starting;
• during a third step, triggering an action on the mobile device, according to the stop message.
