A CELLULAR MOBILE TELEPHONE SYSTEM OF THE TDMA-TYPE HAS A PLURALITY OF MOBILE RADIO UNITS WHICH ARE CONNECTED VIA RADIO CHANNELS WITH A COMMUNICATION NETWORK THAT INCLUDES RADIO BASE STATIONS. MONITORING AND SIGNALLING BETWEEN BASE STATION AND THE MOBILE RADIO UNITS IS EFFECTED WITH AT LEAST ONE SIGNAL FLOW (L2A), AMONG OTHER THINGS RESPONSIBLE FOR MAINTAINING THE PHYSICAL CONNECTION. A SECOND SIGNAL FLOW (L2B) IS USED, WHICH AMONG OTHER THINGS, IS RESPONSIBLE FOR TRANSMITTING CERTAIN DATA (SHORT MESSAGE SERVICE SMS) WHICH IS NOT CONCERNED WITH MAINTAINING THE CONNECTION. ABORTION MEANS (752, 852) PROVIDED FOR ABORTING THE PHYSICAL CONNECTION ARE ACTIVATED SOLELY, IF CONSIDERING THE DATA LINK LEVEL (LEVEL 2), WHEN THE MONITORING MEANS (751, 851) OF THE FIRST SIGNAL FLOW (L2A) INDICATE A BROKEN CONNECTION.
