Abstract
Method and device for measuring the transmission quality in cells of mobile radio networks in which, using a mobile station (MS) comprising a GPS receiver, the cell to be measured is travelled through, and the geographic position and the time are recorded at specified intervals. The signals transmitted from a base transmission station (BTS) to the mobile station as well as a call build-up signal sent at certain intervals, are stored with the GPS position. Furthermore, signals between the base transmission station and the respective mobile station, which signals are sent at specified intervals, are recorded with time stamps by means of a mobile radio analysis device (MA). Subsequently there is a mixing together of the recorded data of the mobile station with the recorded data of the mobile radio analysis device, sorted according to time stamp, with the measured results issued by geographic position and by time. The device and the method make it possible: to acquire the measuring values for both directions; to obtain the geographic position of a problem or to obtain position-related statistics and better information concerning the supply within the cell. Furthermore it is no longer necessary for highly-qualified employees to travel through the cell in a test vehicle.
