Abstract
In CDMA mobile communication systems, there are cases in which communications are interrupted with the local base station while the mobile station is searching for channels other than the communication channel. A method is offered of preventing loss of information due to interruptions in such a case. There are a first transmission step for transmitting signals from the mobile station to the base station at a transmission rate R1 and a transmission output level P1 (when the transmission output is p in FIG. 10C), a suspension step of suspending signal transmissions from the mobile station to the base station (when no transmission output power as shown in the same drawing), and a second transmission step of transmitting signals from the mobile station to the base station at a transmission rate R2 higher than the transmission rate R1 and a transmission output level P2 higher than the transmission output level P1 (when 2p in the same drawing). Due to this second transmission step, it is possible to transmit information which was not transmitted during the suspension period.
