Abstract
According to a first aspect of the invention, a reception level threshold value for standby control is determined on the basis of signaling information received from a base station and information concerning mobile unit reception performance, and standby control is performed by comparing a measured reception level with the reception level threshold value. According to a second aspect of the invention, signaling information containing a BER (bit error rate) threshold value is received from a base station, and standby control is performed by comparing a measured BER with the BER threshold value.
