JPH1075471A - Calling control method for radio call receiver and radio call receiver - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prolong the service life of a battery while effectively utilizing a residual battery capacitance by reporting reception through calling from a speaker even when there is only the residual battery disabling the drive of a vibrator by driving the vibrator when a calling method is set to the vibrator, stopping driving the vibrator when a power supply voltage gets lower than a specified value, and performing calling while switching driving to the speaker. SOLUTION: Concerning the calling operation of a radio call receiver, the voltage of a power source 1 is always monitored by a voltage detector 2. Then, when a control part 3 receives a call and the calling method is set in a vibrator mode, the control part 3 outputs a vibrate signal to a vibrator 4 and drives the vibrator 4. At that time, when the voltage of the power source 1 is lowered and the voltage detector 2 detects the voltage of the power source 1 getting lower than the specified value, a voltage drop signal is outputted from the voltage detector 2 to the control part 3, and the control part 3 stops driving the vibrator and outputs a ringing signal to a speaker 5.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the claimed invention will be described with reference to the drawings. A paging control method for a radio paging receiver according to an embodiment of the present invention, when a call is received in a state where a vibrator mode is set, attempts to drive the vibrator. Is stopped and the speaker is driven instead, so that the remaining battery can be used effectively and the battery life can be extended.

First, the configuration of a first radio paging receiver for realizing the paging control method according to the present invention will be described with reference to FIG. FIG. 1 is a configuration block diagram of a first radio pager according to the present invention. As shown in FIG. 1, a first paging receiver according to the present invention includes a power supply 1, a voltage detector 2,
The control unit 3 includes a control unit 3, a vibrator 4, and a speaker 5.

Next, each section of the first paging receiver of the present invention will be specifically described. The power supply 1 supplies power to the control unit 3. The voltage detector 2 has a constant power supply 1
To detect a drop in the power supply voltage. Specifically, when the voltage of the power supply 1 falls below a predetermined value, a voltage drop signal is output to the control unit 3. I have. Here, the predetermined value is a voltage value at which the vibrator 4 cannot be driven.

The vibrator 4 performs calling by vibration, and is specifically driven by a vibration signal from the control unit 3. The speaker 5 outputs a ringing tone or the like, and is specifically driven by a sound signal from the control unit 3.

The control unit 3 controls the incoming call and various settings of the radio paging receiver, and a feature of the present invention is a paging control process at the time of reception. Therefore, the incoming call processing, various setting processing, and the like are the same as those of a general paging receiver, and a description thereof will not be repeated.

A paging process at the time of reception in the control unit 3 of the radio paging receiver of the present invention will be described with reference to FIG. FIG. 2 is a flowchart showing the flow of a calling process at the time of reception in the control unit 3 of the first radio pager according to the present invention. Note that FIG. 2 shows the processing when the calling method is set to the vibrator mode in advance.

The paging process at the time of reception in the control unit 3 of the radio paging receiver of the present invention is started when a paging is received, a vibration signal is output to the vibrator 4 to drive the vibrator 4 (100), and the voltage detector It is determined from step 2 whether a voltage drop signal has been input (102). If a voltage drop signal has been input (Yes), the vibration signal to the vibrator 4 is stopped and the vibrator 4 is turned off (10).
4) Output a sound signal to the speaker 5 and turn the speaker 5 on.
N (106), the call processing at the time of reception ends.

On the other hand, if there is no input of the voltage drop signal in the process 102 (No), the calling process at the time of reception is terminated.

Next, the paging operation of the radio paging receiver of the present invention will be described with reference to FIG. In the paging operation of the radio paging receiver of the present invention, the voltage detector 2 constantly monitors the voltage of the power supply 1.

When the control unit 3 receives the call and the calling method is set to the vibrator mode, the control unit 3
Outputs a vibration signal to the vibrator 4
Drive.

At this time, when the voltage of the power supply 1 drops and the voltage detector 2 detects that the voltage of the power supply 1 has fallen below a predetermined value, a voltage drop signal is output from the voltage detector 2 to the control unit 3 and the control unit 3 Reference numeral 3 indicates that the vibration signal of the vibrator 4 is stopped to stop driving, a sound signal is output to the speaker 5, and a ringing tone is output.

As another (second) radio paging receiver for realizing the paging control method of the present invention, an A / D converter in a control unit 3 'is used instead of the voltage detector 2 as shown in FIG. There is also a method of detecting the voltage of the power supply 1 in step S6.

According to the paging method of the radio paging receiver of the present invention, the control unit 3 drives the vibrator 4 at the time of receiving a call, and detects a voltage drop from the voltage detector 2 or the A / D converter 6. When the signal is input, the vibration of the vibrator 4 is stopped and the speaker 5 is driven, so that there is an effect that the remaining battery can be used effectively and the battery life can be extended.

In addition, in spite of the vibrator mode, calling by sounding a ringing sound can provide a strong warning to the user that the battery is dead.

[0022]

According to the first aspect of the present invention, when the calling method is set to the vibrator, the vibrator is driven, and when the power supply voltage falls below a predetermined value, the driving of the vibrator is stopped. Since it is a paging control method of a radio paging receiver that switches to driving of paging and makes a call,
Even if the remaining battery capacity cannot drive the vibrator,
Notifying the speaker of the call reception has the effect of effectively using the remaining battery and extending the battery life.

According to the second aspect of the present invention, when the calling method is set to the vibrator, the control unit receives the call and drives the vibrator, and the voltage detector drops the power supply voltage below the predetermined value. When detecting that, the control section stops driving the vibrator in response to the voltage drop signal, and the radio paging receiver drives the speaker. In addition, by notifying the call reception by the speaker, there is an effect that the remaining battery can be used effectively and the battery life can be extended.

According to the third aspect of the invention, when the calling method is set to the vibrator, the control unit receives the call and drives the vibrator, and the A / D converter sets the power supply voltage to the predetermined value. When detecting that the voltage has dropped, a voltage drop signal is output, and the control unit stops driving the vibrator in response to the voltage drop signal and uses the radio paging receiver to drive the speaker. Even so, the notification of the call reception by the speaker has the effect of effectively using the remaining battery and extending the battery life.
