Abstract

PURPOSE:To provide a selective radio call receiver with which the missing of an important call is prevented after the alarm mode is set in a silent mode even if it is forgotten to return an alarm mode to a ringing mode. CONSTITUTION:A decoder 4 is provided with a means for automatically returuing an alarm operation to the ringing mode due to the sounding of a speaker 7 after the lapse of just prescribed time for the state of the silent mode from the setting of the silent mode due to the ON/OFF of an LED 9 for the alarm mode due to the operation of a set switch 14. Therefore, even when a person who carries the receiver inhibits an alarm in the alarm mode for a while and sets the silent mode, the decoder 4 automatically returns the alarm mode to the ringing mode after the lapse of prescribed time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio selective call receiver, and more particularly to a radio selective call receiver with improved call notification means.

[0002]

2. Description of the Related Art Conventionally, in this type of radio selective call receiver, the alerting mode (notifying mode) for notifying the receiver carrier that a call has been made is mainly alerted by an acoustic means (speaker). A sounding mode that produces sound,
Demand has increased due to recent diversification of receiver functions
ED (light emitting diode) There are two modes of silent mode using a notification means (not appealing to acoustic means) by blinking light or vibration of a vibrator. Whether the notification mode is the sounding mode or the silent mode is selected depending on the position of the slide switch installed in the receiver and the switch operation when the power is turned on.

However, as a reliable notification means of the radio selective calling receiver, the sounding mode by the acoustic means is the most reliable, and the notification by the silent mode is effective only in a specific receiver carrying method. is there. In other words, in reporting by vibrating the vibrator, it is effective as a reporting means only if you wear a receiver.
If the receiver is put in a bag, etc., it cannot exert its full effect as a reporting means. Also, the blinking due to the LED light becomes a valid notification only when the receiver carrier can see the blinking. On the other hand, depending on the situation, it is a fact that the notification operation in the ringing mode often makes the receiver wearer and other people annoyed.
Therefore, the receiver carrier needs to select whether the report mode is the ringing mode or the silent mode depending on the situation.

[0004]

However, in the above-mentioned conventional notification mode setting method, it may be necessary to set the notification mode to the silent mode and then forget to return the notification mode to the acoustic mode after the silent mode has been used up. It often happens. Therefore, especially when the receiver wears silent mode when he / she does not want to make a sound for a short time, he may forget to return the notification mode to the ring mode after the end of use and may miss an important call. There was a drawback that there is.

[0005]

The radio selective call receiver having the ringing mode and the silent mode as the call reporting means of the present invention, even if the call reporting mode is set to the ringing mode, the When it is desired to stop the notification in the ringing mode, a means for changing the notification mode to the silent mode for a predetermined time by a switch operation is provided. This radio selective call receiver is
It has a means for automatically returning the notification mode to the ringing mode when the silent mode is set compulsorily or when the predetermined time has elapsed. Also, the receiver is
It is more preferable to provide notification mode return notification means for notifying the receiver carrier that the notification mode has returned to the notification operation in the ringing mode when returning from the silent mode to the ringing mode.

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a radio selective call receiver according to the present invention.

The radio signal received by the antenna 1 is
It is amplified and demodulated in the receiving unit 2. The demodulated received signal is
The waveform shaping circuit 3 converts it into a digital data signal that can be read by the decoder 4.

The decoder 4 compares the data signal output from the waveform shaping circuit 3 with its own selective call number recorded in advance in a P-ROM (programmable read only memory) 5, and they match. Then, an alert signal is output to the amplifier 6 and the amplifier 8 to inform the carrier of the radio selective call receiver that a call has been made.
Further, the decoder 4 analyzes a message signal following the call signal of itself from the data signal and outputs message data based on the analysis result to the LCD driver 10. L
The CD driver outputs a display signal to the LCD display 11 in response to the message data and causes the LCD display 11 to display the received message.

The amplifier 6 amplifies the (speaker) alert signal output from the decoder 4 and drives the speaker 7. The amplified alert signal is converted into an acoustic signal by the speaker 7 and sounded as an alert sound to notify the carrier of the wireless selective call receiver that there is a call. Further, the amplifier 8 amplifies the (LED) alert signal output from the decoder 4 and causes the LED 9 to emit light to notify the radio selective call receiver carrier that there is a call. The notification in the normal sounding mode is performed by both the speaker 7 and the LED 9, and the notification in the silent mode is performed by the LED 9
Only done by.

The clock generator 12 is used to generate a timing clock and an alert signal for synchronizing with a received signal. The power switch 13 turns off the start of this receiver.
N / OFF. The set switch 14 is a push (set) switch for stopping an alert sound, starting an indicator for confirming a message, and setting a silent mode. The memory switch 15 is a push (memory) switch for sequentially recalling a plurality of received messages to the LCD display 11 when storing the received messages. As will be described later, the decoder 4 includes a memory 41, a t1 second timer (t1) 42, and a t2.
Second timer (t2) 43 and t3 second timer (t3) 44
And are built in. The set time of the t3 second timer 44 is preset in the P-ROM 5 according to the desire of the receiver carrier.

FIGS. 2 and 3 are flow charts relating to the shift of the notification operation from the ringing mode to the silent mode in the radio selective calling receiver of the embodiment of FIG.

When the power switch 13 of the radio selective calling receiver shown in FIG. 1 is turned on, the receiver is set to the alert mode of the ringing mode and enters the waiting state for the calling number (step 101). Therefore, when the caller's own number is received in this state, the receiver reports in the ringing mode.

When the set switch 14 is pressed (Y in step 102) in the power-on state (waiting for the call number) in step 101, the decoder 4 causes the decoder 4 to receive the latest received message stored in the memory 41. The message contents are displayed on the LCD display 11 (step 103). At the same time, the decoder 4 activates the t1 second timer 42 for display (step 104). t1 second timer 4
If no switch operation is performed until 2 times out (Y in step 105), the decoder 4 erases the display on the LCD display 11 (step 106), and the receiver receives
It returns to the standby state again (step 107 = 101).

If the memory switch 15 is pressed (N in step 105, Y in step 108) before the t1 second timer 42 times out, the decoder 4 displays the content of the new message next to the currently displayed message on the LCD display 11. Is displayed (step 109). At the same time, the decoder 4 clears the t1 second timer 42 and restarts the timer 42 (step 104). On the other hand, t1
The set switch 14 is pressed before the second timer 42 times out (N in step 108, Y in 110).
Then, the decoder 4 erases the message display on the LCD display 11 (step 111). At the same time, the decoder 4 starts the t2 second timer 43 (step 112).
Then, the t2 second timer 43 counts the pressing time of the set switch 14 (N in step 113, 115). If the set switch is released before the t2 second timer 43 times out (N in step 115), the decoder 4
Starts monitoring the depression of the set switch 14 again (step 113).

On the other hand, the set switch is kept pressed until the t2 second timer 43 times out (step 115).
Y) and the decoder 4 emits a short beep sound from the speaker 7.
The receiver is notified that the notification mode has been set (step 116) and the notification mode has been set to the silent mode (step 117). At the same time, the decoder 4 starts the t3 second timer 44 (step 118). t3
When the second timer 44 times out (Y in step 119), the decoder 4 informs the speaker 7 of a short sound three times (step 120), and returns the notification mode to the sound mode (step 121). Inform the person.

In step 119, if the set switch 14 is pressed before the t3 second timer 44 times out (N in step 119, Y in 201), the radio selective call receiver shifts from the silent mode to the ringing mode reporting operation. Transition.

FIGS. 4 and 5 are flowcharts of the notification operation relating to the shift from the silent mode to the sounding mode notification operation in the embodiment of FIG.

When step 201 Y is executed, the decoder 4 of FIG. 1 displays the latest message content among the received messages stored in the memory 41 on the LCD.
It is displayed on the display 11 (step 202). At the same time, the decoder 4 activates the display t1 second timer 42 (step 203). If no switch operation is performed until the t1 second timer 42 times out (step 204)
Y), the decoder 4 erases the display on the LCD display 11 (step 205), and again the above-mentioned t3 second timer 4
The timeout of 4 is checked (step 119).

If the memory switch 15 is pressed (N in step 204, Y in 206) before the t1 second timer 42 times out, the decoder 4 displays the new message content next to the currently displayed message on the LCD display. 11 is displayed (step 207). At the same time, the t1 second timer 42 is cleared and restarted (step 20).
3). If the set switch 14 is pressed before the t1 second timer 42 times out (Y in step 208), the decoder 4 erases the message display on the LCD display 11 (step 209). At the same time, the decoder 4 starts the t2 second timer 43 (step 210) and counts the pressing time of the set switch 14 (steps 211 and 212). If the set switch 14 is released before the t2 second timer 43 times out (Y in step 211), the decoder 4 checks again for the time out of the t3 second timer 44 (step 119).

On the other hand, when the set switch 14 is continuously pressed until the t2 second timer 42 times out (Y in step 212), the decoder 4 makes a short beep to the speaker 7.
A notification is given (step 213) to inform the receiver wearer that the notification mode has been set to the ringing mode (step 214), and the operation starts (step 215 = 10).
Return to 1).

As described above, according to the present invention, when the notification operation of the radio selective call receiver is in the ringing mode, the means for changing the notification operation to the silent mode by the switch operation and the silent for a predetermined time. When the mode state elapses, it has means for automatically returning the notification operation from the silent mode to the ringing mode. Even if you do, the receiver's notification mode automatically returns to the ringing mode after the set time elapses, so you forget to change the notification mode from the silent mode to the ringing mode and miss an important call. It has the effect of eliminating the fear of.
