Mobile wireless telephone nearby presence detecting method, involves extracting measurement report message addressed to base station of current cell, and informing presence of message emitted by telephone in active reception state

摘要

#CMT# #/CMT# The method involves measuring power, emitted by a wireless telephone, during a time division multiple access (TDMA) frame that is dedicated to a control channel. A measurement report message is extracted, which is addressed to a base station of a current cell during the TDMA frame. The presence of the message is informed, where the message is emitted by the wireless telephone in an active reception state. #CMT#USE : #/CMT# Used for detecting the nearby presence of a mobile wireless telephone (claimed) in an active reception state. #CMT#ADVANTAGE : #/CMT# The method permits to detect the presence of the mobile wireless telephone in active reception state, so that the wireless telephone can be switched off by a user during a predetermined period, and hence undesired sounds in a public place can be eliminated in a simple manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a simplified block diagram of a device for detection of a mobile wireless telephone in an active reception state. 1 : Power measurement unit 2, 4, 5 : Configuration units 3 : Measurement report extraction unit 6 : Information unit.
