Method for transmitting signaling messages between first and second network units, and radio communication system and base station subsystem therefor

Abstract

In a communication system having a first network unit and a second network unit, a plurality of subscriber units which transmit and receive signaling messages to the second network unit are provided in the first network unit. The signaling messages of the subscriber units are in each case divided into a first class of signaling messages and into a second class of signaling messages. The signaling messages are transmitted between the first network unit and the second network unit via a common link. In the case where a measured utilization of the common link exceeds a first threshold, the transmission of signaling messages assigned to the second class is interrupted for all subscriber units. In the case where the measured utilization of the common link drops below the first threshold and exceeds a second threshold which is lower than the first threshold, the transmission of signaling messages assigned to the second class can be interrupted for some subscriber units.
