Title (EN) A RADIO SYSTEM
(FR) SYSTEME RADIO
Abstract:
(EN) The invention relates to a radio system comprising several fixed radio stations (BS1, BS2, BS3), and at least one mobile radio station (MS1, MS2, MS3) signalling with a single fixed radio station at a time, the system further comprising at least one frequency channel serving as a control channel and time-shared between several fixed radio stations for the transmission of control signalling. To shorten the average call set-up time, the length of a signalling period assigned to each fixed radio station (BS1, BS2, BS3) on said control channel is variable between minimum and maximum values specific for each particular radio station on the basis of the number of messages received by the fixed radio station and messages to be transmitted from the same radio station.
(FR) L'invention concerne un système radio comprenant plusieurs stations radio fixes (BS1, BS2, BS3), et au moins une station radio mobile (MS1, MS2, MS3) communiquant avec une seule station radio fixe à la fois, le système comprenant également au moins un canal de fréquences servant de canal de commande et utilisé en temps partagé entre plusieurs stations radio fixes pour la transmission de la signalisation de commande. Pour raccourcir le temps moyen d'établissement d'appel, la longueur d'une période de signalisation affectée à chaque station radio fixe (BS1, BS2, BS3) sur ledit canal de commande est variable entre des valeurs minimales et maximales spécifiques à chaque station radio donnée sur la base du nombre de messages reçus par la station radio fixe et de messages à transmettre depuis la même station radio.
