Abstract

PURPOSE:To immediately generate a warning from a base station, by detecting which has exceeded a transmitting time or is continuing an abnormal intermittent transmission, among a lot of mobile stations using the same channel in common. CONSTITUTION:In case when detecting signals E, F of an H level are not outputted from both a continuous transmitting time detecting circuit 5 and a repetitive transmission times number detecting circuit 6, an overall detecting circuit 7 does not generate a detecting output B. On the other hand, when one detecting signal E or F of the continuous transmitting time detecting circuit 5 and the repetitive transmission times number detecting circuit 6 becomes an H level, the voltage of a capacitor C5 of the overall detecting circuit 7 becomes an H level, and the detecting signal B becomes an L level, therefore, a discriminating signal generator is started and its discriminating signal is transmitted to the base station. The base station derives a corresponding mobile station from its discriminating signal, and takes proper steps such as a warning, etc. immediately.
