Title (EN) CELLULAR RADIO SYSTEM ALLOWING MOBILE STATION TO COMMUNICATE THROUGH BASE STATION CONNECTED VIA CDMA RADIO CHANNEL, AND BASE STATION DEVICE AND MOBILE STATION DEVICE USED IN THE SAME
(FR) SYSTEME RADIOCELLULAIRE PERMETTANT AUX STATIONS MOBILES DE COMMUNIQUER PAR L'INTERMEDIAIRE DES STATIONS DE BASE CONNECTEES VIA UN CANAL RADIO CDMA, ET STATION DE BASE ET STATION MOBILE UTILISEES DANS CE SYSTEME
Abstract:
(EN) A cellular radio system wherein a CPU (42a) monitors a channel utilization rate for each of a plurality of radio frequencies allocated to each of a plurality of base stations (BS). When a difference among channel utilization rates determined for the plurality of radio frequencies allocated to a base station (BS) indicates a predetermined condition, the CPU (42a) exchanges a candidate radio frequency to be used by a predetermined mobile station (MS) among mobile stations (MS) that are present in a cell formed by the base station (BS) and in an idling state for reception to a radio frequency to a radio frequency whose channel utilization rate is in the predetermined condition.
(FR) Dans ce système radiocellulaire, une unité centrale (CPU) (42a) surveille un taux d'utilisation de canal pour chacune des fréquences radio attribuées à chacune des stations de base (BS). Lorsqu'une différence entre ces taux d'utilisation de canal déterminés pour les fréquences radio attribuées à une station de base (BS) indique une condition prédéterminée, l'unité centrale (42a) échange une fréquence radio candidate à utiliser par une station mobile prédéterminée (MS) parmi les stations mobiles (MS) qui sont présentes dans une cellule formée par la station de base (BS) et en état d'inoccupation en vue de la réception sur une fréquence radio dont le taux d'utilisation de canal se trouve dans l'état prédéterminé.
