Abstract

En mobil stasjon (23) omfatter en effektdetektor (2) i en gjennonsnittsberegnende krets (3) og en signalfadingsdetektor (4). Effektdetektoren måler kanalsignaleffekten (mottatt signaleffekt) i et mottatt signal mottatt av en mottager (1). Den gjennomsnitts-beregnende krets beregner gjennomsnittet for den mottatte signaleffekt målt ved hjelp av effektdetektoren. Signalfadingsdetektoren påviser svekkelse i kanalsignaleffekten med gjennomsnittet av den mottatte signaleffekt når svekkelse i det mottatte signal påvises mens en anropsanmodning eller anropsrespons blir sendt, vil, etter at den mottatte signaleffekt er gjenvunnet, en styrekrets (5) i den mobile stasjon sende anropsanmodningen eller anropsresponsen ut på ny. Når svekkelse i det mottatte signal påvises like før en anropsanmodning eller-anropsrespons sendes, stanser styrekretsen i den mobile stasjon utsendelsen av anropsanmodningen eller -responsen. Etter at den mottatte signaleffekt er gjenvunnet, sender styrekretsen i den mobile stasjon ut anropsanmodningen eller -responsen.
