摘要： This invention relates to a portable terminal equipment which receives intermittently a control channel transmitted from a cell station in a standby state. When the equipment shifts to the standby state, the equipment is brought into a receiving state to receive intermittently the control channel (PCH) for a set period of time W1 at every 1.2 seconds (ST22-ST25 and ST32). In addition, the equipment judges the receiving state from judging information of the receiving state such as the intensity of the electric field in receiving time and the presence/absence of an error in the received data (ST27 and ST33). In a power saving mode, when the equipment keeps on receiving the control channel in a good state for a set period of time while the equipment receives the control channel at every 1.2 seconds, the equipment is brought into a receiving state to receive the control channel at every 2.4 seconds (ST33-ST35). When the equipment does not receive the control channel in a good state while the equipment receives the control channel at every 2.4 seconds, the equipment shifts directly to the receiving state to receive the control channel at every 1.2 seconds (ST33 and ST32). In the standby state, when the equipment keeps on receiving the control channel in a good state, the interval between each reception of the control channel becomes longer and thus the power consumption of the equipment is saved.

摘要： This invention relates to a portable terminal equipment using a battery as a power source. The equipment determines whether or not battery voltage VB is lower than a voltage value V1 in a standby state or a speaking state (ST1 and ST8). The voltage value V1 is set to such a value that the equipment is capable of generating an outgoing call and making a speech during a set period of time, when the battery voltage VB is equal to the value V1. When VB

摘要： This invention relates to a portable terminal equipment establishing synchronism with a control channel by intermittently receiving the control channel when the synchronism with the control channel is made off. When the synchronism with the control channel is made off, the equipment is set to a control channel receiving state for a period of time W2 every period of time t1 (ST3-ST10). When the synchronism with the control channel is not established in the receiving state which is set to N (=X+5) times (X=number of off-synchronism during the past one hour), the equipment is set to shifting to a control channel receiving state for the period of time W2 every period of time t2 (ST2 and ST11-ST18). The more frequently a user moves, the larger the time X of off-synchronism becomes and thus N becomes larger by that amount so that a time period until the interval t1 between each period of the control receiving state is shift to the interval t2, is prolonged. Therefore, when the user moves frequently and the possibility of the equipment entering the service area of the cell station from the outside is high, the control channel receiving state brings about frequently. When the user does not move frequently and the possibility of the equipment entering the service area of the cell station from the outside is low, the frequency of bring about the control channel receiving state becomes low and thus emphasis is laid on the consumption of the battery.
