Abstract

In a method for testing the transmission quality of a radio channel in a cell radio system having a TDMA structure, a mobile station (MT) periodically measures values (x) of the received field strength. An evaluating unit (AW) calculates from the field strength measured values an average field strength (x) and also the fourth moment (M) and establishes the difference (D) between the two. Depending on whether this difference is below a limiting value, the frame error rate is used as an additional quality measure.
