Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile communication terminal apparatus and an incoming call notification means control method, and more particularly, to a mobile communication terminal apparatus that automatically switches incoming call notification means according to the possessed state of the mobile terminal. The present invention relates to a notification means control method.
[0002]
[Prior art]
Mobile communication devices are rapidly becoming smaller and lighter, and recently mobile phones that can be carried in breast pockets have appeared. These small mobile communication devices are not limited to chest pockets, but are also special cases. Is attached to the waist and heel with a belt, or it is carried in an attache case, handbag, second bag or briefcase.
[0003]
By the way, the incoming call notification in this type of mobile communication terminal is mainly performed by ringing a sounding body such as a ringer incorporated in the mobile communication terminal. This incoming call notification by the ringer is performed regardless of the mobile method. In addition, since it is required that the owner can hear it without being erased by ambient noise, the surroundings are often disturbed by a sudden loud sound.
[0004]
For example, if there is a ringer notification by a ringer in a place where a quiet environment is required, such as a music concert or a library, it may cause trouble to the surroundings. Means are sought. As means for preventing such trouble due to noise, there are known functions such as a function of adjusting the volume of a ringer and a so-called manner mode notification of a call by a vibrator.
By the way, in such a conventional form communication terminal, the ringer volume change and the ringer notification from the ringer to the incoming call notification by the vibrator, so-called manner mode change, requires manual setting of the portable communication terminal holder. there were. However, such manual mode setting may be forgotten, and is not always satisfactory in terms of convenience.
[0005]
In particular, in order to reduce the ringer volume, the portable communication terminal holder needs to adjust the ringer volume to an appropriate value according to the portable method in order to obtain the optimal ringer volume. For the ringer volume adjustment in the terminal, a method is adopted in which the volume setting value adjusted using a mechanical volume or electronic volume is directly applied to the drive control unit of the sound generator, so that the current volume setting value is changed. In order to obtain the optimum volume for a pocket or bag cell phone, it is necessary to make adjustments and actually try such a portable method each time. There was a problem that it was difficult to change the ringer volume immediately according to the change of the carrying method, which had to be repeated many times.
[0006]
Therefore, as a ringer volume automatic changing means for solving these problems, a technique disclosed in Japanese Patent Laid-Open No. 2000-314737 is known.
That is, this technology aims at ringtone control of a mobile communication terminal that can automatically notify an incoming call at a ringer volume suitable for the portable method of the mobile communication terminal without relying on the key input of the carrier, The ring tone control device includes posture detection means for detecting the posture of the mobile communication terminal, and controls the ring volume based on the posture of the mobile communication terminal detected by the posture detection means.
However, in this prior art, the volume of the ringtone is controlled by the attitude of the terminal, and the attitude sensor detects the attitude by a mechanical mechanism, so that a dynamic force such as vibration is applied to the mobile terminal. If added, there was a risk of malfunction. Furthermore, there is a possibility of causing a failure due to mechanical damage depending on the handling method. In addition, since the sensor is constructed with mechanical parts, there is a limit to reducing its weight.
[0007]
[Problems to be solved by the invention]
The present invention has been made to eliminate the drawbacks of the prior art described above, and can easily detect the possessed state of the mobile communication terminal and can automatically set the incoming call notification means according to the possessed state. The purpose is to realize a portable communication terminal.

DETAILED DESCRIPTION OF THE INVENTION
[0016]
(First reference example )
Hereinafter, a first reference example of the present invention will be described with reference to FIG.
FIG. 1 is a block diagram showing a circuit configuration of a mobile communication terminal provided with an automatic switching means to a manner mode according to the present invention.
In FIG. 1, reference numeral 1 denotes an antenna for use in communication in a mobile communication terminal, and this antenna is connected to a mobile communication terminal circuit 2 for performing communication with a base station such as a mobile phone. A temperature sensor 4 is used as information for determining the possession state of the mobile communication terminal, and its output is input to the determination control circuit 3. Based on the temperature information from the temperature sensor 4, the determination control circuit 3 can notify that the portable communication terminal is held in close contact with the human body and that the owner has received an incoming call with the manner mode notification. It is determined whether or not, and the switching circuit 5 is controlled to set the incoming call notification means. When an incoming call is received in the mobile communication terminal circuit, the ringer circuit or vibrator is activated in accordance with the setting of the incoming call notification means switched by the determination control circuit to notify the owner of the mobile communication terminal of the incoming call.
A storage device 9 is connected to the determination control circuit, and data for determining the output of the temperature sensor 4 is stored therein.
[0017]
Next, the operation of the ring tone control apparatus for a mobile communication terminal configured as described above according to the present invention will be described in detail.
In FIG. 1, a mobile communication terminal circuit 1 is a mobile phone circuit, and although not shown in detail, it measures the time during which a radio transmission / reception unit, signal processing unit, handset, control unit and ringer are ringing. A circuit having a main function of a portable communication terminal including a time measuring unit.
When the mobile communication terminal circuit 1 receives the incoming signal from the radio base station, the mobile communication terminal circuit 1 transmits a signal indicating that the incoming call notification is being received to the determination control circuit 3. In response to this signal, the determination control circuit 3 transmits a signal for starting temperature measurement to the temperature sensor 4 and at the intermediate temperature between the preset temperature and the human body temperature from the storage device 9. Acquire data of a certain reference temperature.
[0018]
Next, the determination control circuit 3 that has acquired the measured temperature from the temperature sensor 4 compares the reference temperature with the measured temperature. If the measured temperature is higher than the reference temperature, the portable communication terminal It can be judged that it is held in close contact with the human body, such as in a pocket, and can notify the owner of the portable communication terminal enough by the notification by the vibrator without performing the notification by the ringer. The switch of the switching circuit 5 is switched to the activation of the vibrator 8, the incoming call notification signal is transmitted, and the vibrator is activated.
On the other hand, when the measured temperature is lower than the reference temperature, the portable communication terminal determines that the portable communication terminal holder has the portable communication terminal in a place that is not in close contact with the human body, such as a bag, and the switching circuit 5 The ringer is switched to ringer ringing, the incoming call notification signal is transmitted, and the ringer is activated.
[0019]
The mobile communication terminal circuit 1 measures the time during which the vibrator is activated by the timekeeping unit. If the mobile communication terminal circuit 1 is not in an off-hook state for a predetermined time (for example, about 10 seconds), the portable communication terminal circuit 1 Can be determined to be placed in a place such as a bag where vibrations by a vibrator cannot be perceived, and the incoming call notification means can be switched to ringer ringing. In this case, in the comparison between the measured temperature of the initial temperature sensor 3 and the reference temperature, there is a possibility that the setting of the reference temperature may not be appropriate, and the reference temperature is set so that the measured temperature is determined to be lower than the reference temperature. Can be changed. By accumulating such learning, the effect of improving the accuracy of determination can be expected.
[0020]
In the above description, switching of the incoming call notification means has been described as being performed when an incoming call is received. However, when the incoming call signal is received and switched, when the incoming call notification is received, the incoming call notification means is set. In addition, a certain time, that is, a so-called time lag is required until the incoming call notification is output. In order to reduce this time lag, the output of the temperature sensor is constantly monitored, and when there is a change in temperature, the incoming call notification means at the time of non-incoming call by comparing with the reference temperature based on the measured temperature May be switched.
[0021]
In the above procedure, as the reference temperature, the reference temperature may be set and input to the storage device based on the average air temperature or the human body temperature, or the portable communication terminal holder may The reference temperature can be set freely. Moreover, the portable communication terminal holder can also measure the temperature and the body temperature using the temperature sensor, and set it as the reference temperature. Specifically, the temperature sensor portion of the portable communication terminal is held so as to accurately measure the temperature. For example, after the temperature is measured by pressing a setting button, the hand is pressed against the temperature sensor. The body temperature is measured, the body temperature is measured by pressing the setting button, and the reference temperature can be determined from these temperatures. In addition, when extremely high temperature is detected, such as when left in a car in fine weather, it is judged that it is not held by the human body and automatically switched to Ringer, or there is a risk that the high temperature environment may damage the equipment In order to notify the user, the ringer may be sounded in a predetermined pattern.
[0022]
(Second reference example )
FIG. 2 is a block diagram showing a circuit configuration of a mobile communication terminal apparatus according to a second reference example of the present invention. However, in the following description, the same components as those described with reference to FIG.
[0023]
4a is a first temperature sensor, and 4b is a second temperature sensor. That is, in this reference example , the situation where the communication terminal is placed is detected by one temperature sensor in the first reference example , but in this reference example , this determination is made by two temperature sensors. Like to do. Thereby, determination with higher accuracy is possible.
[0024]
FIG. 3 shows an external view of the communication terminal according to this embodiment.
In FIG. 3, reference numeral 21 denotes a casing of the mobile communication terminal, which is provided with an antenna 22, a speaker 23, a liquid crystal display element 24, a button group 25, and a microphone 26, and further on the surface of the casing. A first temperature sensor 27 and a second temperature sensor 28 are disposed on the back surface of the housing.
[0025]
Next, the operation of this reference example will be described in detail.
First, similarly to the first reference example , temperature data of a human body temperature and air temperature, and a reference temperature determined from these data are stored in the storage device.
When there is an incoming call notification from the base station, the determination control circuit receives the received signal from the mobile communication terminal circuit, and the determination control circuit activates the first and second temperature sensors 4A and 4B to obtain temperature information measured by these sensors. get.
Next, the measured temperature of these two temperature sensors is compared with the reference temperature. If the two measured temperatures are both lower than the reference temperature, the portable communication terminal is stored in a bag or bag, In such a case, the switching circuit 5 is set so that the incoming call notification is made not by the vibrator but by the ringer ringing. .
[0026]
On the other hand, if one of the two temperature sensors is higher than the reference temperature and the other one is lower than the reference temperature, the mobile communication terminal is placed in a close contact with the human body, such as a human breast pocket. In this case, the switching circuit 5 is set so as to notify the incoming call by the activation of the vibrator 8.
Further, when both of the two temperature sensors 4A and 4B are higher than the reference temperature, it is determined that the portable communication terminal is in the palm of a person, and this is also switched to the incoming call notification by the vibrator 8.
[0027]
At this time, the time during which the vibrator 8 vibrates is measured by the time measuring unit of the mobile communication terminal circuit 1, and if the mobile communication terminal circuit 1 is not in an off-hook state for a predetermined time (for example, about 10 seconds), It is determined that the person puts the mobile communication terminal inside the bag or the like where the vibration of the vibrator 8 is blocked, the switching circuit 5 is switched to the ringer circuit 6 side, the ringer is sounded by the sounding body 7 and carried Inform the communication terminal holder of the incoming call.
[0028]
(Third reference example )
FIG. 4 shows a circuit block diagram of the portable communication terminal device of this reference example .
In this embodiment, the mobile communication terminal of the present invention is characterized in that a humidity sensor is provided in addition to the temperature sensor. That is, when the mobile communication terminal is in close contact with the human body, the temperature measured by the sensor is higher than the air temperature, and at the same time, the humidity is likely to be higher than the atmospheric humidity. Accordingly, if the humidity data from the humidity sensor is used together with the measured temperature data in determining the state of possession of the portable communication terminal in addition to the measurement by the temperature sensor, the determination can be made with higher accuracy.
That is, when the reference temperature and the measured temperature are compared, it is difficult to determine the possession state of the portable communication terminal if these two temperatures are almost equal or within the range considered as a measurement error. If such a determination is difficult, a more realistic determination can be made by using this humidity measurement value.
[0029]
Next, the operation of this reference example will be described in detail.
First, similarly to the first reference example , temperature data of human body temperature and temperature, and a reference temperature determined from these data are recorded in the storage device. In this embodiment, in addition to these data, atmospheric humidity data is also required. As the humidity data, the measurement value of the humidity sensor built in the portable communication terminal is always measured, and the value with the lowest humidity measurement value is set as the atmospheric humidity. In this case, when the mobile communication terminal is held in close contact with the human body, the humidity rises due to perspiration, so the lowest value of the measured values is assumed to be the atmospheric humidity. In this reference example , when this humidity is higher than the reference humidity, this atmospheric humidity is set as the reference humidity and the measured humidity measured by the humidity sensor built in the mobile communication terminal is compared with this reference humidity. It is determined that the portable communication terminal is held in close contact with the human body.
[0030]
Specifically, when there is an incoming call notification from the base station, the determination control circuit 3 issues a measurement start signal to the temperature sensor 4 and the humidity sensor 10, and acquires the respective measurement data. The determination control circuit 3 that has acquired data from the temperature sensor 4 and the humidity sensor 10 first compares the measured temperature with the reference temperature recorded in the storage device 9, and the difference between the measured temperature and a predetermined error range or more. If the temperature exceeds the reference temperature, it is determined that the portable communication terminal is held in close contact with the human body, and the switching circuit 5 is set to activate the vibrator 8. On the other hand, if the measured temperature is below the reference temperature by a difference of a predetermined error range or more, the switching circuit 5 is set so that the portable communication terminal is held in a state not in close contact with the human body and the ringer circuit is activated. Set. If the difference between the measured temperature and the reference temperature is within a predetermined error range, it is difficult to make a determination using only the information from the temperature sensor, and a determination is made by comparing the measured humidity with the reference humidity. In this case, if the measured humidity is equal to the reference humidity, the mobile communication terminal is carried in the atmosphere, and the ringer circuit 6 is activated so that it is not carried closely to the human body. If the measured humidity is higher than the reference humidity, the mobile communication terminal is set to activate the vibrator on the assumption that it is closely held by the human body. Thereafter, the mobile communication terminal circuit 1 outputs an incoming call notification signal, and performs ringer ringing or vibrator activation.
[0031]
( First embodiment)
In addition to the features of the mobile communication terminal device described in the first or second reference example , the mobile communication terminal according to the present embodiment has a date acquisition function and a time acquisition function built-in, The temperature is predicted based on the date and time, and is used as data for determining the reference temperature when determining the state of possession of the portable communication terminal based on the temperature measured by the temperature sensor.
In other words, in Japan, the temperature change is extremely large in summer and winter, and at night and during the day, and when the above-mentioned reference temperature is determined based only on the average annual temperature, the above judgment may occur frequently. It is done. In such a case, a database for determining the temperature for the date and time data is built in the storage device 9, and the temperature information is searched from the date and time acquired by the date and time acquisition function, Determine the reference temperature. If the possession state determination of the mobile communication terminal is performed using this reference temperature, determination with higher accuracy becomes possible.
[0032]
Next, the operation of this embodiment will be described in detail.
In the storage device, the data of the average temperature is recorded in advance for the date and time of the main city.
When the incoming notification is received from the base station, the determination control circuit acquires the measured temperature from the temperature sensor. On the other hand, the current time is acquired by the date and time acquisition function, and the temperature average value of the current time is acquired from the database stored in the storage device 9 together with the preset current position information. From the average temperature value and the body temperature data of the person accommodated in the storage device 9, an intermediate value of these temperature data is set as the reference temperature. Next, the measured temperature and the reference temperature are compared to determine the possessed state of the mobile communication terminal in the same manner as the determination procedure in the first embodiment, and the incoming call notification means is based on the result. After switching, the incoming call notification is performed.
Thereby, the reference temperature closer to the actual environment can be set, and the accuracy of determination is improved.
[0033]

That is, the reference temperature used in the above reference examples and embodiments is average temperature data that does not take into account factors such as location, season, and time, or is predicted from the location, date, and time. Temperature data was used. For this reason, there is a possibility that the reference temperature does not necessarily correspond to the actual possession situation. Therefore, in this embodiment, if the weather data of the environment where the mobile communication terminal is placed is obtained and the reference temperature is determined based on the weather data, determination with higher accuracy becomes possible. Therefore, in the present embodiment, this weather data is obtained from a base station having jurisdiction over the mobile communication terminal. Therefore, it is expected that determination will be easy and accurate if realistic temperature data is available.
This weather data may be based on information obtained at a general weather observation facility such as the Japan Meteorological Agency, or may be data measured at each base station, each base station having its own temperature sensor and humidity sensor.
[0034]
In the above embodiment, when determining whether or not the portable communication terminal device is held in close contact with the human body using the output measurement value of the temperature sensor, the output of one temperature sensor is used. The output value of each temperature sensor is used, or the measurement value of the humidity sensor is used together, the temperature data predicted based on the seasonal data obtained by the calendar function and the clock function built in the portable communication terminal device is used An example and an example in which temperature data of a place where the mobile communication terminal device is located are obtained from the base station of the mobile communication terminal and used for the determination are shown.
In the present invention, each of these methods may be used alone for determination, but these determination means may be used in combination for determination with higher accuracy.
That is, two temperature sensors and one humidity sensor are provided, and the determination may be made using the predicted temperature value obtained by the calendar function and the clock function, or the predicted temperature value obtained from the calendar and the clock function. Instead, the determination can be performed using the temperature data of the area notified from the base station.
[0035]
Furthermore, a set button is provided on the portable communication terminal device, the portable communication terminal device is brought into close contact with the human body, the value of the temperature sensor at that time is stored, and this can be used as the reference data of the human body temperature.
[0036]
【The invention's effect】
