Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a selective call receiver having a silent call mode as a call notification mode, a call notification method thereof, and a wireless communication device.

(Prior Art) Conventionally, for example, the following is known as a selective call receiver. FIG. 4 is a circuit block diagram showing the configuration.

In FIG. 1, a selective call signal sent from a base station (not shown) is received by a radio circuit 2 via an antenna 1, demodulated by a demodulation circuit 3, and introduced into a matching circuit 4.
In the collating circuit 4, the individual number code (ID code) included in the above-mentioned reception selective calling signal is collated with the ID code of the own device stored in the individual number code memory (ID-ROM) 5 in advance. . When the codes match, it is determined that a call to the own device has occurred, and the collation circuit 4 outputs a call notification instruction to the call notification control circuit 6. Then, a ringing signal is supplied from the call notification control circuit 6 to the drive circuit 7, whereby a ringing sound is generated from the speaker 8 to notify the holder of the occurrence of the call.

If a message code is included in the reception selective calling signal, the collation circuit 4 performs error correction and decoding of the message code. Then, the decoded message code is supplied to the display drive circuit 9,
As a result, a message corresponding to the message code is displayed on the display 10. The received message code is sent from the matching circuit 4 to the message memory (M-RAM) 11.
Is transferred and stored. The message code stored in the message memory 11 is displayed when the display switch 12 is operated after the display of the message is completed.
And is displayed again on the display 10.

Conventionally, this type of selective call receiver includes a call notification mode, as described above, in addition to a ringing call mode in which a ringing sound is generated to notify the occurrence of a call, as well as a light emitting diode (LED) or the like. Some devices have a so-called silent call mode in which the occurrence of a call is notified by blinking or generating vibration of the light emitting element. Use of this silent call mode is very convenient because it is possible to notify the holder of the occurrence of a call without generating a ringing sound in places where quietness is required, such as a conference room or a lecture hall. .

(Problems to be Solved by the Invention) However, in this type of conventional selective call receiver, if the receiver is accommodated in an inner pocket or a case and carried in a silent call mode, for example, a call occurs. However, there is a problem that the holder may not notice this call, which causes a problem in case of an emergency call.

On the other hand, as a means for solving this problem, for example, the receiver is provided with an ID code dedicated to a ringing call different from the ID code used for normal calling, and when this ID code is received, for example, It has been considered to make a ringing call even if the silent call mode is set.

However, in such a method, two ID codes must be assigned to each receiver. Here, the upper limit is set in advance for the number of ID codes that can be assigned to each frequency in one system. For this reason, two
The conventional method of assigning ID codes has a problem that the number of receivers (the number of subscribers) that can be accommodated in one system is reduced by half, and effective use of radio waves cannot be achieved.

Therefore, the present invention focuses on the above points, and even when the holder does not notice the call notification, it is possible to reliably report the occurrence of a call, and without requiring a plurality of individual number codes. It is an object of the present invention to provide a selective call receiver and a method of notifying the call that can be implemented by one kind of individual number code, thereby having excellent notification performance, preventing a decrease in the number of subscribers, and enabling effective use of radio waves. .

Another object of the present invention is to provide a wireless communication device having excellent notification performance and a notification of an incoming call even when the holder is unaware of the incoming call notification. It is to provide a method.

[Configuration of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a selective call receiver for performing a call notification in response to a selective call signal sent from a base station, using an audible sound. The first call notifying means for making a call notification, the second call notifying means for making a silent call notification, and which of the first call notifying means and the second call notifying means is set in advance. Call notification setting means for detecting the brightness of the surrounding area, brightness / darkness determination means for detecting whether or not the illuminance is equal to or less than a predetermined threshold value, and the second call notification means by the call notification setting means. A call notification changing means for operating the first call notification means to make a call notification when a call is generated in the set state and the surrounding illuminance is determined to be equal to or less than a threshold value by the light / dark judgment means. Characterized by .

Further, in another aspect of the present invention, when a call is generated from a base station, a first call notification method of performing call notification by an audible sound, or a second call notification method of performing call notification by silence, In a call notification method for performing a call notification by a preset call notification method, when a call from a base station occurs in a state where the second call notification method is set, the surrounding illuminance is detected and the illuminance is detected. Is determined to be equal to or less than a predetermined threshold value, and when the surrounding illuminance is determined to be equal to or less than the threshold value, a call notification is performed by a first call notification method.

Another aspect of the present invention is a wireless communication device that performs an incoming call notification according to a signal transmitted from a base station, a first incoming call notification unit that performs an incoming call notification using an audible sound, and a second incoming call notification that performs a silent incoming call notification. Incoming call notifying means, incoming call notifying setting means for setting in advance which of the first incoming call notifying means and the second incoming call notifying means should be operated, and detecting the surrounding illuminance and setting the illuminance to a predetermined value. An incoming call occurs in a state where the second incoming call notifying means is set by the incoming call notifying means, and the surrounding illuminance is reduced by the light and dark determining means. An incoming call notification changing unit that operates the first incoming call notifying unit to notify the incoming call when it is determined to be equal to or less than the threshold value.

Further, in another aspect of the present invention, when an incoming call from the base station occurs, the first incoming call notification method of performing an incoming call notification by an audible sound, or the second incoming call notification method of performing an incoming call notification by a silent sound, In the incoming call notification method for performing an incoming call notification according to a preset incoming call notification method, when an incoming call from a base station occurs in a state where the second incoming call notification method is set, the surrounding illuminance is detected and the illuminance is detected. Is determined to be less than or equal to a predetermined threshold value, and when the surrounding illuminance is determined to be less than or equal to the threshold value, incoming call notification is performed by a first incoming call notification method.

(Operation) As a result, according to the present invention, when the holder does not notice the call notification, for example, when the receiver is carried in a pocket or in a case and carried. When a call is generated from the base station, the surrounding brightness is determined. When it is determined that the receiver is in the dark state, it is determined that the receiver is housed in a pocket or a bag, and thereby the call notification mode is changed. For this reason, even if the receiver is carried in an inner pocket or case, the occurrence of a call is reliably notified to the holder, thereby eliminating the problem that the holder does not notice the call notification. . In addition, since it is not necessary to set a plurality of individual number codes and the processing can be performed with one individual number code, the number of subscribers that can be accommodated in the system can be increased and effective use of radio waves can be achieved.

According to another aspect of the present invention, in the wireless communication device, even if the telephone is housed in an inner pocket, a bag, or the like while the silent incoming call notification mode is specified, an incoming call is not generated to the holder. The notification is made surely, whereby the problem that the holder does not notice the incoming call notification is solved.

(Embodiment) FIG. 1 is a circuit block diagram showing a configuration of a selective call receiver according to one embodiment of the present invention. 4, the same parts as those in FIG. 4 are denoted by the same reference numerals, and detailed description is omitted.

The selective call receiver according to the present embodiment inputs a call notification control circuit 60 for controlling a plurality of kinds of call notification modes, a light emitting diode (LED) 13 which emits light in a silent call mode, and a call notification mode. Mode selection switch for
14 and an illuminance detection circuit 15 are newly provided. Among them, the illuminance detection circuit 15 has, for example, a phototransistor and detects the illuminance around the receiver.

The call notification control circuit 60 includes a microcomputer as a main control unit, and includes a notification mode setting unit 61, a light / dark determination unit 62, and a notification mode change unit 63 as its functions.

The notification mode setting means 61 sets the call notification mode to the mode specified by the switch 14 when the mode specifying switch 14 is operated. The call notification mode includes a sound notification mode in which a sound is generated and a silent notification mode in which a call is notified by blinking the LED 13 without generating a sound.

The brightness determining means 62 inputs a detected value of the surrounding illuminance from the illuminance detection circuit 15 when a call notification instruction is generated from the matching circuit 4 in a state in which the silent notification mode is set,
This illuminance detection value is compared with a preset threshold value. Then, it is determined whether or not the illuminance detection value has dropped below the threshold value.

The notification mode changing means 63 changes the silence notification mode currently set to the sound notification mode when the lightness / darkness determination means 62 determines that the illuminance detection value has fallen below the threshold value. Call notification is performed in the ringing call mode.

Next, the operation of the selective call receiver configured as described above will be described according to the control procedure of the call notification control circuit 60.

In the call waiting state, the call notification control circuit 60 repeatedly monitors the arrival of the call notification instruction and the operation of the mode designation switch 14 in steps 2a and 2b as shown in FIG. 2 (a).

When the mode specifying switch 14 is operated in this state, the call notification control circuit 60 proceeds to step 2c and inputs the call notification mode specified by the mode specifying switch 14, and in step 2d, sets the call notification mode. Is stored in the internal memory. For example, if the owner specifies the ringing sound notification mode, the ringing sound notification mode is held in the internal memory of the call notification control circuit 60, while the holder specifies the silent sound notification mode for use in a conference room or the like. Then, the silent notification mode is held in the internal memory of the call notification control circuit 60.

Now, when a call is issued from the base station to its own device and a call notification instruction is output from the matching circuit 4, the call notification control circuit 60 proceeds from step 2a to step 2e, and in this step 2e, the current call is stored in the internal memory. The called call notification mode is determined. As a result of this determination, if it is determined, for example, that the mode is the sound notification mode, the call notification control circuit 60 proceeds to step 2i.
Then, a sound signal is output to the drive circuit 7. Then, a drive current corresponding to the sound signal is supplied to the speaker 8 by the drive circuit 7, whereby a sound is generated from the speaker 8, and the owner is notified by a sound that a call has occurred.

When the ringing notification by this sound starts, the ringing notification control circuit 60 determines whether or not a stop switch (not shown) has been operated in steps 2j and 2k as shown in FIG. Is repeatedly determined.
If the stop switch is operated or if a certain time elapses before the stop switch is operated, step
The flow shifts to 2l, where the generation of a sound is stopped, and the process returns to the call waiting state.

On the other hand, as a result of the call notification mode determination in step 2e, when it is determined that the sound notification mode is set, the call notification control circuit 60 inputs the illuminance detection value from the illuminance detection circuit 15 in step 2f. Then, in step 2g, it is determined whether or not the detected illuminance value is equal to or less than a preset threshold value. As a result of this determination, if it is determined that the illuminance detection value is higher than the threshold value, the call notification control circuit 60 determines that the selective call receiver is in a place where the cycle is now bright, and as it is, FIG. The process proceeds to step 2m as shown in (2). Then, a drive signal is output to the LED 13 here. Then LED13
Blinks, thereby visually informing the holder that a call notification has occurred. Therefore, in a place where quietness is required, such as a conference room, it is possible to know that a call has occurred without bothering other people.

When the call notification by the LED 13 occurs, the call notification control circuit 60 repeatedly monitors the operation of the stop switch and the elapse of a predetermined time in steps 2n and 2o. Then, if the stop switch is operated or if the fixed time elapses even if this stop switch is not operated, the blinking of the LED 13 is stopped in step 2p, and then the state returns to the call waiting state.

By the way, as a result of the comparison between the detected illuminance value and the threshold value in the step 2g, when it is determined that the detected illuminance value is equal to or less than the threshold value, the call notification control circuit 60 determines that the periphery of the selected call receiver is dark. . That is, it is determined that the selective call receiver is in the pocket of the holder or in the bag.
Then, the call notification control circuit 60 proceeds from step 2g to step
The process proceeds to 2h, where the call notification mode is changed from the silent notification mode to the ringing notification mode. Then, in step 2i, a sound signal is output to the drive circuit 7, and a sound is generated from the speaker 8.

Therefore, even if the owner keeps the selective call receiver in a place where it cannot be seen like a pocket or a bag while the call notification mode is set to the silent notification mode, the owner can surely know the occurrence of the call by sounding. Can be.

As described above, according to the present embodiment, when a call from the base station occurs in a state where the silent notification mode is set,
The surroundings are determined to be dark and dark, and if it is determined that the surroundings are in a dark state, the ringing notification mode is changed from the silent notification mode to the ringing notification mode, and the ringing notification mode is used to perform the ringing notification. Therefore, even if the holder is stored in a pocket or a bag with the silent notification mode set, the occurrence of the call can be reliably notified. Therefore, it is possible to prevent a problem that the call from the base station is not transmitted to the holder, thereby improving the notification performance. Further, it is not necessary to assign a plurality of individual number codes to each selective calling receiver, thereby increasing the number of subscribers in one system.

Next, another embodiment of the present invention will be described. FIG. 3 shows a schematic configuration of the mobile phone in the embodiment.

The mobile phone includes a transmitter (Tx) 22 and a receiver (Rx) 23 for which a transmission / reception channel is specified by a synthesizer 21.
It has. Then, during a call, a radio call signal arriving via a radio line is received and demodulated by a receiver via a reception antenna 24, and then output as a voice from a receiver 25.
On the other hand, the speech signal input from the transmitter 26 is modulated by the transmitter 22 and then transmitted to the wireless line via the transmission antenna 27.

In addition, the wireless telephone includes a transmission switch 28, a dial key 29, and a sounder 31 that emits a sound when an incoming call occurs, and a light emitting device that emits a light when an incoming call occurs, as circuits necessary for various controls related to outgoing and incoming calls. Diode LED32
And a notification mode specifying switch 33 for specifying an incoming notification mode, and an illuminance detection circuit for detecting ambient illuminance.
And 34. This illuminance detection circuit 34 is constituted by, for example, a phototransistor.

By the way, the mobile phone of the present embodiment includes a control circuit 30 including a microcomputer. This control circuit 30
In addition to ordinary control means such as a control means for setting a wireless line with a base station (not shown) at the time of outgoing and incoming calls, a notifying mode setting means 35 as means relating to incoming call notification, It comprises a judging means 36 and a notification mode changing means 37.

The notification mode setting means 35 includes a notification mode designation switch 33.
When the is operated, this switch 33
Is set to the mode specified by. The ringing notification mode includes a ringing sound notification mode for generating a ringing sound,
There is a silent notification mode in which an incoming call is notified by blinking the LED 32 without generating a sound.

The light / dark judging means 36 is provided with an illuminance detecting circuit when an incoming call is detected in a state in which the silent notification mode is set.
A detected value of surrounding illuminance is input from 34, and the detected illuminance value is compared with a preset threshold value. Then, it is determined whether or not the illuminance detection value has dropped below the threshold value.

The notification mode changing means 37 changes the silent notification mode being set to the sound notification mode when the lightness / darkness determination means 36 determines that the illuminance detection value has fallen below the threshold value. Incoming call notification is performed in the sound calling mode.

With such a configuration, in a state where the silent notification mode is set by the incoming notification mode specifying switch 33,
Assuming that an incoming call has occurred from a base station (not shown), the control circuit 30 first inputs a current illuminance detection value from the illuminance detection circuit 34, and determines whether the illuminance detection value is equal to or less than a predetermined threshold value. Is determined. If the illuminance detection value is larger than the threshold, the mobile phone is placed on a desk, for example,
It is determined that the holder can visually recognize the LED 32, and the LED 32 is driven to blink as it is to display an incoming call by light.

On the other hand, if it is determined that the illuminance detection value is equal to or less than the threshold, the mobile phone is housed in, for example, a pocket or a bag, and the holder determines that the LED 32 cannot be visually recognized, and The notification mode is changed from the silent notification mode to the ringing notification mode. A sound signal is supplied to the sounder 31 in accordance with the sound notification mode, thereby generating a sound and notifying the holder of the occurrence of an incoming call by sound.

As described above, according to the present embodiment, in a state in which the silent notification mode is set in the mobile phone having the silent notification mode in addition to the ringing notification mode as the incoming notification mode,
When an incoming call is received from a base station (not shown), the surrounding light / dark is first determined, and if the surrounding is determined to be dark, the silent notification mode is determined to be inappropriate and the mode is automatically changed to the ringing notification mode. Incoming call notification by ringing sound is made, so while the incoming call notification mode is set to the silent notification mode,
Even if the holder accommodates the mobile phone in his pocket or bag, if an incoming call is generated from the base station, the occurrence of the incoming call can be clearly notified to the holder by a sound. Therefore, the problem that the bearer does not notice that the incoming call has occurred from the base station is solved.
Therefore, the incoming call notification performance of the mobile phone can be improved.

It may be something. Further, as a means for detecting the surrounding light and darkness, other light receiving elements such as a photodiode and a solid-state imaging device may be used in addition to the phototransistor. In addition, the present invention may be applied to any device other than the selective call receiver and the mobile phone as long as the device has a silent notification mode, and other notification control procedures and contents thereof may be applied to the present invention.
