One kind of the boot phone examination method for detecting and identifying

A method of detecting and identifying the start of the examination method of a mobile phone, to detect and identify the phone signal. 1) In the examination room arrangement of the sensor; 2) received signal strength of the initialization of the system for monitoring a threshold value; 3) no sensor measures the radio spectrum intensity of the ambient boot phone as an initial received signal reference intensity vector; 4) the sensor real-time monitoring neighboring radio spectrum strength; 5) by a calculation of the test statistic L (u); switched phone alert 6) If L (u) is greater than the test threshold received signal strength monitoring is issued is present; 7) from the measured and the sensor coordinates from algorithm weight average power calculated position of the phone; 8) if not issued in step 6) in the examination room in the boot memory warning phone, the sensor of the received signal strength reference vectors updated, the current received signal strength vector as a new reception signal strength reference vectors ,, returns to step 4).
