[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of notifying a user of a mobile communication terminal such as a mobile phone when a call is received.

[0002]

2. Description of the Related Art First, a conventional portable communication terminal will be described with reference to FIGS.

FIG. 1 is a block diagram of a conventional portable communication terminal.

In FIG. 1, 101 is a transmitter, 102 is a transmission signal processing unit, 103 is a wireless transmission unit, 104 is a duplexer, 105 is an antenna, 106 is a wireless reception unit, 107 is a reception signal processing unit, 108. Is a handset, 109 is a high frequency part,
110 is a baseband unit, and 111 is an MPU.

The voice signal input from the transmitter 101 is
The transmission signal processing unit 102 performs signal processing, the radio transmission unit 103 modulates the radio-frequency signal into a high-frequency signal, which is amplified and then transmitted from the antenna 105 via the demultiplexer 104. On the other hand, the reception signal received by the antenna 105 is sent to the wireless reception unit 106 via the demultiplexer 104, demodulated there, and then reproduced as an audio signal via the reception processing unit 107 and the receiver 108. .. The MPU 111 controls the entire system and connects communication lines.

FIG. 2 is a state transition diagram of a conventional portable communication terminal.

In FIG. 2, 201 is a power-off state,
202 is a standby state, 203 is a notification state, 204 is a call state, and 205 is an outgoing state. Each state 201 to 20
The transition from 5 is shown by a solid line.

The standby state 202 is a state in which the user waits for a call to be made by pressing a dial number key or the like, or a state in which an incoming call is waited for. Notification state 2
Reference numeral 03 indicates a state in which, for example, the user is notified of an incoming call when the incoming call is received.

As a method of notifying the user of an incoming call, there are a notification method by emitting a sound from a sounder, a notification method by blinking a light emitting body such as an LED, or a notification method by a vibrator. Japanese Patent Laid-Open No. 1-188126
As described in Japanese Patent Publication No. JP-A-2003-264, there has been devised a method in which a user can preset an arbitrary notification method among these notification methods.

[0010]

As described above, the representative notification methods are sound, light, and vibration. However, depending on the state of the portable communication terminal, these methods notify the user of an incoming call. It may be impossible or inappropriate. That is, when the portable communication terminal is acoustically cut off from the user, sound notification is impossible,
When it is optically blocked, it is impossible to notify by light. Further, when the vibrator is not in contact with the user, it is impossible to notify by vibration.

Therefore, there is a trouble that the user must determine the most appropriate notification method according to the state of the portable communication terminal and set the notification method in advance before receiving the call. Further, even if the setting is made once, if the state of the mobile communication terminal changes, the previously set notification method may not be appropriate. Therefore, the user is informed every time the state of the mobile communication terminal changes. , You need to set it again.

As described above, in the above-mentioned conventional technique, the most appropriate notification method cannot be automatically selected from the plurality of notification methods according to the state of the portable communication terminal.

Further, as described in JP-A-3-7433, the ambient brightness of a portable communication terminal and the presence / absence of use of a mounting clip are detected, and the luminous intensity is detected according to the detection result. There are some cases in which the notification by light is made non-operation when it is below a certain standard, that is, when it is dark, the notification by sound and the notification by light are made non-operation when the clip is used, and the notification by vibration is made non-operation when the clip is not used. As a result, the incoming call can be reasonably notified according to the state of the portable communication terminal, and the life of the battery can be extended.

However, since the above-mentioned prior art does not judge the states of portable communication terminals of various types,
The optimum notification method is not necessarily selected according to the state of the portable communication terminal, and even if the selected notification method is appropriate, it may be quantitatively inappropriate. That is, it may be assumed that the volume, light amount, and vibration amount are insufficient or excessive for the user to recognize. In the above-mentioned conventional technology, since the notification amount cannot be automatically adjusted, the user does not always notice the notification, and it cannot be said that the notification is optimal for the user.

An object of the present invention is to provide a portable communication terminal capable of notifying an incoming call by selecting an optimum notification method and notification amount for the user according to the state of the portable communication terminal. Especially.

[0016]

In order to achieve the above object, the present invention provides a portable communication terminal equipped with a plurality of notifying means for notifying a user of an incoming call. , Each having a plurality of levels of notification amount, and detecting means for detecting at least all or part of the placement of the portable communication terminal, the ambient illuminance, the ambient noise, and the voltage of the power supply, The state of the portable communication terminal is judged based on the detection result of the detecting means, and one or more notifying means corresponding to the state are selected from the plurality of notifying means, and one or more selected ones are selected. Each of the notifying means is provided with a notifying control means for selecting the notifying amount according to the state from the notifying amounts of the plurality of stages.

The notification control means has a first table showing a correspondence relationship between the detection result of the detection means and a predetermined state of the portable communication terminal, and a predetermined state of the portable communication terminal. And, it is possible to have a second table showing a correspondence relationship between one or more notification means and the notification amount according to the state. In this case, the notification control means determines the state of the portable communication terminal by referring to the first table based on the detection result of the detecting means, and refers to the second table. By doing so, the notification means and the notification amount are selected according to the determined state of the portable communication terminal. The first table and the second table are
You can also combine them into one.

Then, the notification control means changes the notification amount or selects another notification means when a predetermined time has elapsed since the selected notification means started the notification. You can do so.

It is also possible to provide a detection means for detecting that the user has touched the portable communication terminal,
In this case, the notification control means, when the detection means detects that the user touched the portable communication terminal while the notification means is performing the notification,
The notification amount can be changed to a smaller value.

Further, the present invention is connected to an external terminal device so that the user can rewrite the contents of the first table and the second table, and the external terminal device is connected. And an information input / output unit for inputting / outputting information to / from the first table and the above-mentioned first table based on the contents input from the external terminal device by the input / output unit. The contents of the second table can be rewritten. Further, a display means for displaying the first table and the second table and an input means for inputting information are provided, and the notification control means is based on the contents input from the input means. The contents of the first table and the second table can be rewritten.

[0021]

From the way of placing the portable communication terminal, it can be seen whether the portable communication terminal is standing or lying down. Also, from the ambient illuminance, it can be known whether the portable communication terminal is used in a bright place or a dark place.

For example, if notification is given by sound during the meeting,
Sound notification is not appropriate because it tends to disturb others. Also, since meetings are usually held in bright places,
The notification control means, when the portable communication terminal is standing, and when it is detected that the portable communication terminal is used in a bright place, does not select the notification method by sound, the notification method by light It is possible to make a selection. In this way, the user only needs to stand the portable communication terminal during the conference.

The ambient noise also indicates whether the portable communication terminal is used in a noisy place or a quiet place.

For example, when the user is crowded,
Since the surrounding noise is large, the user may not notice the incoming call unless the notification is given by a loud noise. Therefore, the notification control means, when it is detected that the portable communication terminal is used in a noisy place, selects the notification method by sound, and further selects the notification amount at the stage of producing the loudest sound. Can be

Further, the voltage of the power source shows whether the remaining amount of the battery is larger or smaller than a predetermined amount.

For example, when the remaining amount of the battery is low, it is preferable to save the battery consumption. Therefore, the notification control means, when it is detected that the remaining amount of the battery of the portable communication terminal is less than a predetermined amount, selects the notification method by sound, further, the notification amount of the stage that emits the smallest sound. You can choose.

The examples given above are merely examples, and thus, the notification control means judges the state of the portable communication terminal based on the detection result of the detection means, One or more notification means and the notification amount thereof are selected according to the state. Therefore, according to the state of the portable communication terminal, it is possible to notify the user of the incoming call with an optimum notification method and notification amount for the user.

3 is an internal configuration diagram of a sensor unit 114 and an information input / output unit 115. FIG.

In FIG. 4, 114a is a noise sensor for detecting the ambient noise level, 114b is a placement sensor for detecting the placement of the portable communication terminal, 114c is an optical sensor for detecting the ambient illuminance, and 114d is a portable sensor. A touch sensor that detects that the user has touched the communication terminal, 114e is a voltage monitoring sensor that detects the remaining battery level, and 114f is an RTC (Real Time Clock) that measures the current time.

Further, 113a is a sounder and 113b is L
ED, 113c is a vibrator, 401 is an A / D converter, 40
2 is an SCI (Serial Communication Interface) terminal, and 700 is a notification selection table.

The noise sensor 114a measures ambient noise using, for example, a microphone and outputs "1" if the noise is a predetermined value or more, and outputs "0" otherwise. Therefore, the noise sensor 114a may be used together with the transmitter 101.

The optical sensor 114c measures ambient illuminance by using, for example, a phototransistor (diode),
If the brightness is equal to or higher than a predetermined value, "1" is output, and if not, "0" is output.

The touch sensor 114d is provided, for example, with a metal (electrically conductive material) or the like at a portion which is in contact with the user when the user holds the portable communication terminal, and when the user holds the portable communication terminal and a current flows through it. Output "1", otherwise output "0".

The placement sensor 114b contacts the side A when the portable communication terminal is standing, and contacts the side B when the portable communication terminal is lying down, for example, as shown in FIG. Such a simple switch is provided to output "1" if the contact is on the A side and "0" otherwise. Further, for example, an optical sensor is provided on the bottom surface of the portable communication terminal, and if it is measured that the optical sensor has a brightness equal to or higher than a predetermined value, “1” is output, and if not, “0” is output. To do.

FIG. 6 is an external view of the portable communication terminal of this embodiment, in which the above-mentioned sensor section 114 is arranged as shown.

In the present embodiment, as a method of notifying the user of an incoming call, a sounding method by the sounder 113a (a sound notifying method), a notification method by the LED 113b (a light notifying method), and a notification method by the vibrator 113c ( There are three types of notification methods (vibration notification method). Then, each notification method is divided into three levels of magnitude, strength (notification amount), such as sound intensity, and the like.

In this embodiment, the optimum notification method is automatically selected from the three notification methods according to the state of the portable communication terminal, and the optimum notification method is selected from the three notification amounts. It allows the amount to be selected automatically.

FIG. 7 is a diagram showing an example of the contents of the notification selection table 700.

As shown in FIG. 7, in this embodiment,
The states of the mobile communication terminal are assumed to be “in a meeting”, “in a pocket”, “busy”, “midnight”, “battery exhausted”, and “others”.

If "in a meeting", a notification method using light is adopted in order to prevent the notification sound from disturbing others, and the notification amount is "large (" 3 "). To

If it is "in the pocket", the sound notification method and the vibration notification method are adopted, and the notification amounts are set to "large" and "medium (" 2 "), respectively. This is because the portable communication terminal may be in a pocket or in a bag, so that both cases are supported. In other words, if it is in your pocket, it is in close contact with your body, so you will be notified by vibration.
This is because if it is in the bag, a loud sound will be issued.

Further, if "busy", it is desired to use a sound notification method to make the notification sound louder, so that the notification amount is set to "large".

If it is "midnight", the sound notification method and the light notification method are adopted, and the notification amounts are set to "small (" 1 ") and" medium ", respectively. This is because it is desirable to reduce the notification sound during the night.

If the "battery is dead", a notification method by sound is adopted, and the notification amount is set to "small" in order to save the battery.

If "other", the sound notification method and the light notification method are adopted, and both the notification amounts are "medium".

The determination of each state is made based on the output of the sensor unit 114.

"Being in a meeting" means that the placement sensor 1
14b outputs "1", the optical sensor 114c outputs "1", the voltage monitoring sensor 114e outputs "0", and R
It is determined when the current time output by the TC 114 is not in the midnight time zone (“1”). This presupposes that the user stands the portable communication terminal on the desk during the meeting, and it is possible that the portable communication terminal is standing in the pocket or bag. The surrounding illuminance is also used as a criterion. Therefore, if the user wants to give a notification by light instead of sound in consideration of annoyance to others during the conference, he or she may put the portable communication terminal on a desk.

Also, "in pocket" means that the optical sensor 114c outputs "0" and the voltage monitoring sensor 114
It is determined when e outputs “0” and the current time output by the RTC 114 is not the night time zone (“1”).
Since it is assumed that the portable communication terminal is put in the pocket or the bag except at midnight, the ambient illuminance and the time are used as the judgment material.

Also, "being busy" means that the noise sensor 114a outputs "1" and the voltage monitoring sensor 114e.
Is judged when "0" is output.

Also, the fact that it is "midnight" means that the optical sensor 1
14c outputs "0", and the noise sensor 114a outputs "0".
Is output, and the voltage monitoring sensor 114e outputs “0”,
It is determined when the current time output by the RTC 114 is the time zone of midnight (“0”).

The "battery exhaustion" is determined when the voltage monitoring sensor 114e outputs "1".

In FIG. 7, "*" means that any output result is acceptable.

Next, the operation of this embodiment will be described.

The state transition diagram of the portable communication terminal of this embodiment is similar to the conventional state transition diagram shown in FIG.
Shows a flowchart from the standby state 202 to the call state 204.

As shown in FIG. 8, in the standby state 202 (step 801), if there is an incoming call (step 8)
02), the MPU 111 outputs the output of the noise sensor 114a,
By reading the output of the placement sensor 114b, the output of the optical sensor 114c, the output of the voltage monitoring sensor 114e, and the output of the RTC 114f (step 803), and referring to the notification selection table 700 based on the read result, the portable communication terminal And the notification method and notification amount corresponding thereto are determined (step 804).

First, when it is determined that the battery has run out (step 805), a notification method corresponding thereto is used (step 806). If it is determined that the traffic is "busy" instead of "dead" (step 8)
07), and a notification method corresponding thereto is used (step 808). When it is determined that the battery is in the pocket instead of the "battery exhausted" and the "busy" (step 809), a notification method corresponding thereto is issued (step 810). Further, when it is determined that it is "in a meeting" instead of "battery exhausted", "busy" and "in pocket" (step 811), a notification method corresponding thereto is notified (step 812). Also, "battery exhausted",
Not in "busy", "in pocket" and "in a meeting"
If it is determined that it is "midnight" (step 81)
3), and notify by a corresponding notification method (step 8)
14). If it is determined that the battery is not exhausted, is busy, is in a pocket, is in a meeting, or is in the middle of night ("other"), the notification is made by another notification method (step 815). ).

Then, the MPU 111 makes a notification by a notification method according to the state, and at the same time, the touch sensor 114
The output of d is monitored (step 816), and touch sensor 1
When "1" is output from 14d, the notification amount is reduced as if the user noticed the incoming call and touched the portable communication terminal (step 817). This prevents the notification from continuing at the same notification amount from when the call is noticed until the call key is pressed, or when the call cannot be made even if the call is noticed. It also has the effect of saving money.

Subsequently, the MPU 111 monitors the interruption by the call key (step 818) and, if the call key is pressed, starts the call (step 819). On the other hand, if the call key is not pressed, the timer is counted (step 820), and if the timer times out, the notification amount and notification means are changed (step 82).
2). Further, depending on the setting of the user, it is possible to change the notification method when the state of the portable communication terminal changes during the notification, and in such a case (step 823). Return to step 803, and if not set, return to step 816.

In the process of step 822, for example, in the case of "in a meeting", when the notification is made by the light and the call key is not pressed even after the lapse of the predetermined time, the user receives the call. As a thing that you do not notice, change to emit a small amount of notification sound, and if the call key is not pressed even after the predetermined time has elapsed, change to increase the volume, and even if the predetermined time has elapsed. When the call key is not pressed, the volume can be changed to be low in order to reduce the consumption of the battery. In addition, for example, when the battery is dead, if a sound alert is given and the call key is not pressed even after a lapse of a predetermined time, the volume is reduced to reduce battery consumption. can do. These processes can be changed according to this notification change table by providing a notification change table (not shown) similar to the notification selection table 700 of FIG. 7.

In the present embodiment, the user can change the contents of the notification selection table 700 to set a unique notification method and notification amount.

This can be realized by rewriting the notification selection table 700 from an external terminal device such as an external personal computer or an electronic notebook through the SCI 402 of the information input / output unit 115 as shown in FIG.

As a rewriting method, the notification selection table 700 may be displayed on the screen so that the user can freely rewrite it, but this may cause confusion, so that FIG.
As shown in, it is preferable to use a selection method.

In FIG. 10, the state of the terminal is first displayed, and subsequently, the changeable condition, the notification method and the notification amount in the selected state are displayed. The user uses a mouse or a keyboard to select an arbitrary item for each item.

For example, as shown in FIG. 10A, the user turns the portable communication terminal aside during the conference, and
If you want to be notified by a small sound, first select "in a meeting". At this time, the placement and the brightness are displayed as the conditions that can be changed. Next, the user selects "horizontal" for the placement, "bright" for the brightness, "ON" for the sound, "ON" for the light, "OFF" for the vibration, and the volume is "small". ，
Select the amount of light as "high". In addition, for example, FIG.
As shown in, if the user wants to be notified by a loud sound even at night, the user first selects “midnight”. At this time,
Since there are no conditions that can be changed, the user subsequently selects "ON" for sound, "ON" for light, and "OFF" for vibration.
Select "High" for the volume and "Medium" for the light intensity.

The contents changed by the user are SCI4.
It is input to the portable communication terminal through 02, and MPU111
Is based on what is entered through SCI401,
The notification selection table 700 is rewritten.

Further, the contents of the notification selection table 700 can be rewritten by the portable communication terminal itself. This is to provide a key for rewriting on the portable communication terminal itself,
When this key is pressed, a rewriting screen similar to the above may be displayed. It should be noted that the function keys may be used together without being dedicated keys. Further, the rewriting screen is preferably scrolled.

Further, when the IC card can be inserted into the portable communication terminal, this IC
The notification selection table 700 may be stored in the card. Notification selection table 7 stored in the IC card
00 makes it possible to change the contents using an external terminal device, and also to change the contents in the portable communication terminal itself. In addition, this IC card
It may be used together with an IC card for address book. In addition, an IC card (ROM card) storing a notification selection table 700 for various types such as a type convenient for the "in a meeting" state and a type convenient for the "in a pocket" state is prepared in advance by the manufacturer. If the user inserts the IC card freely selected from them, the trouble of rewriting the notification selection table 700 is eliminated.

The setting of whether or not to change the notification method when the state of the portable communication terminal changes during the notification as described above is similar to the rewriting of the notification selection table 700.
This can be done through SCI 402.

Further, although the portable communication terminal is placed vertically and horizontally in this embodiment, it is not limited to this. In addition, the information control unit 112 uses the MPU 111.
Not limited to the above, it can be configured by a wired logic. Therefore, since it can be easily added to the MPU used conventionally, it is not necessary to increase the number of chips. It is also possible to provide a dedicated chip.

Further, in the present embodiment, the above-mentioned three types of notification methods are used as the incoming call notification method, but the present invention is not limited to this, and the notification amount may be any number of levels instead of three levels. ..

As described above, according to this embodiment,
The notification method and the notification amount can be automatically selected according to the state of the portable communication terminal to notify the incoming call, and the contents of the notification selection table 700 can be rewritten. The incoming call can be notified by the notification method and the notification amount that are optimal for the user.

In addition, as the equipment to be added to the existing configuration for realizing this embodiment, the placement sensor 114 is used.
b, the optical sensor 114c, the noise sensor 114a, the touch sensor 114d, the SCI 402, etc., and the noise sensor 11
4a can also be used as the transmitter 101 included in the portable communication terminal. Therefore, when the function of this embodiment is installed in an existing portable communication terminal, the structure is very simple and the manufacturing cost is extremely low.

[0076]

As described above, according to the present invention,
