Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a portable telephone terminal,
The present invention relates to a method of notifying power information performed in a mobile phone terminal and a method of limiting additional functions added to the mobile phone terminal.

[0002]

2. Description of the Related Art A portable telephone terminal is carried and used, and a rechargeable battery is used as a power supply source. Also, it is necessary to keep the functions of the mobile phone terminal operable for as long as possible without frequently charging the rechargeable battery mounted on the mobile phone terminal. In, the power consumption of the mobile phone terminal is reduced and the function of the mobile phone terminal can be maintained for a longer time with one charge.

[0003] However, in the case of a mobile phone terminal, so-called standby reception is performed to detect an incoming call to its own device unless the main power supply is turned off. Consumes power stored in the battery. For this reason, the mobile phone terminal notifies the user of the remaining amount of power stored in the mounted battery (hereinafter, referred to as the remaining amount of the battery in this specification), and according to the remaining amount of the battery. Therefore, when the user does not make a call, the user can take measures such as turning off the power of the mobile phone terminal or charging the mobile phone terminal early.

[0004] The notification of the remaining battery level of the mobile phone terminal is made by, for example, an LCD (Liquid) provided in the mobile phone terminal.
This is performed by, for example, displaying a remaining amount display icon on the Crystal Display. In this case, the notification of the remaining battery level may include a plurality of battery remaining states, such as a fully charged state, a low battery state, and a low battery state. The notification is performed in stages.

[0005]

However, the conventional notification of the remaining battery level of a portable telephone terminal does not clearly indicate how long the function of the portable telephone terminal can be maintained. Therefore, if the user sees the notification of the remaining battery level of the mobile phone terminal and determines that there is no need to return to home and charge the battery, as described above, the call from the mobile phone terminal is taken into account. Or turn off the mobile phone terminal and use the answering machine service provided by the telephone company.

[0006] However, even if it is notified that the battery level of the mobile phone terminal is running low, if it is only a few hours before returning home and charging,
The amount of power that can be used as usual with the mobile phone terminal, that is, the amount of power that can be used for making and receiving calls and for talking on the phone, may be left in the battery. It is believed that there is. Until such a case, it is not preferable that the user may restrict the use of the mobile phone terminal by himself.

[0007] In addition, it is considered that various additional functions are mounted on a portable telephone terminal. For example, music / sound recording function, music / sound reproduction function, image / text information recording function, recorded image / text information reproduction function, position information display function, PDA (Personal Data A)
There is a sistant function (so-called electronic organizer function) and the like, and it is considered that not only one of these functions but also a plurality of functions are installed.

[0008] In a portable telephone terminal equipped with one or more such additional functions, the use of the additional functions accelerates the consumption of power stored in a battery mounted in the portable telephone terminal. . For this reason, it is conceivable that the additional function is used, and if the user notices, the power stored in the battery runs out, and the telephone function cannot be used.

To cope with this, it is conceivable to always leave a fixed amount of power in the battery mounted on the mobile phone terminal. However, in this method, a certain amount of power is always left in the battery for the telephone function, so that the amount of power for using the additional function is limited. However, it is not possible for the user of the mobile phone terminal to manage the power required for the telephone function and the power required for the additional function, and control the use of the telephone function and the use of the additional function. difficult.

[0010] In view of the above, the present invention provides a portable telephone terminal capable of accurately managing the remaining battery power, a power information notification method and an additional function limiting method used in the portable telephone terminal. The purpose is to do.

Then, the expected call time that will be performed before charging is calculated from the expected standby time, the number of calls per day, and the call time per call. The power consumption that is consumed when a call is made for the expected call time is obtained, and the relationship between the power consumption and the remaining power of the battery is reported.

Thus, when the remaining power of the battery is larger than the power consumption consumed when making a call for the expected talk time, it is possible to perform only the call normally performed. Can be notified to the user. If the remaining power of the battery is less than the amount of power consumed when making a call for the expected talk time,

Power consumption in the case where the power consumption has occurred. In addition, a call history including a start time and an end time of a call is recorded in a call history memory, and the number of calls per day is obtained from the call history.
The call time required for one call is calculated.

From the expected standby time, the number of calls per day, and the call time required for one call, the expected call time that will be performed before charging is calculated. The power consumed when making a call for the expected call time is required. Then, charging is started from the present time by adding the power consumption consumed when performing standby reception for the expected standby time and the power consumption consumed when performing conversation for the expected call time. Until the expected time, the amount of power required to maintain the telephone function is calculated. The relationship between the required power amount and the remaining power amount of the battery is reported.

Accordingly, when the remaining power of the battery is larger than the required power, it is possible to inform the user that the standby reception and the telephone conversation which can be normally performed can be sufficiently performed. In addition, when the remaining power of the battery is smaller than the required power, the user can be notified that it is necessary to take measures such as charging.

From the expected standby time, the number of calls per day, and the call time required for one call, the expected call time of the call that will be performed before the charging is started is calculated. The power consumed when making a call for the expected call time is required. Then, from the power consumption consumed when performing the standby reception for the expected standby time and the power consumption consumed when performing the call for the expected call time, from the current time to the time when charging will be started. , The amount of power required to maintain the telephone function is calculated.

Based on the relationship between the required power and the remaining power of the battery, control is performed so that additional functions other than the telephone function are restricted.

The latest charging start time is recorded in the memory, and if the difference between the currently detected charging start time and the immediately preceding charging end time is shorter than a predetermined time, the currently detected charging start time is stored in the memory. Do not record in.

For example, immediately after the mobile phone terminal is put on the charging stand, the mobile phone terminal is taken down from the charging stand, and immediately after that, the mobile phone terminal is put on the charging stand again. This is because if the charge start history is recorded in the memory each time, the expected standby time cannot be obtained accurately and quickly. As a result, only the accurate charging start history can be recorded in the memory, so that the expected standby time can be calculated accurately and quickly.

The following describes an example of such a case.

FIG. 2 is a block diagram for specifically explaining portable telephone terminal 100 of this embodiment shown in FIG. As shown in FIG. 2, the control unit 150 of the mobile phone terminal 100 includes a CPU 151 and a ROM (Read On).
ly Memory) 152 and RAM (Random)
Access Memory) 153 and EEPRO
M (Electrically Erasable a
nd Programmable ROM) 154,
The clock circuit 41 is connected through the CPU bus 155.

Here, the ROM 152 stores programs to be executed by the CPU 151 and necessary data such as display fonts in advance. Also,
The RAM 153 is mainly used as a work area, and stores data in the middle of calculation as necessary while the CPU 151 is executing the program, and stores the data in the control unit 1.
This is used for temporarily storing data exchanged between the device 50 and each unit.

[0049] The EEPROM 154 is used for the mobile phone terminal 10.
For example, when the power supply of 0 is turned off, the setting conditions immediately before are stored, and when the usage method is set to make the same setting at the next power-on, the setting parameters are stored. It is used to store charging start history information and call history information for several days. That is, the EEPROM 154 is a non-volatile memory that does not lose data stored therein even when the power of the mobile phone terminal 100 is turned off.

The control unit 150 includes a key input unit 31
Are connected through a key I / F (I / F is an abbreviation of interface; hereinafter the same in this specification) 31A, and the LCD 32 is connected through an LCD controller 32C. The control unit 150 includes the ringer 3

For example, it is possible to notify the user of the state of the mobile phone terminal 100 to the user or to issue a warning about an illegal operation through the ringer 32, the ringer 33, and the LED.

A clock circuit 41 corresponding to the clock function section 4 is connected to the control section 150. Clock circuit 41
As described above, can provide the current time, has a calendar function, and can provide the current date and day of the week. Further, it is provided with a so-called timer function for detecting arrival of a set time.

Then, the mobile phone terminal 1 of this embodiment
00, charging terminals T1 and T2 (charging terminals T1 and T2 in FIG. 1) for connecting to an external charging device 200.
Corresponding to. ) Is connected, and a rechargeable battery 51 (corresponding to the battery 5 in FIG. 1) is mounted. A charging device connection detecting unit 61 is provided between the charging terminal and the battery 51.
(Corresponding to the charging device connection detecting means 6 in FIG. 1).

The charging device connection detecting section 61 used in the mobile phone terminal 100 of this embodiment detects, for example, a change in voltage, so that the mobile phone terminal 100
It is set in the power receiving device 200 and the charging device 20
0 is electrically detected, and this is detected by the control unit 15.
Notify 0.

The control unit 150 includes a charging device connection detecting unit 61
Is notified that the mobile phone terminal 100 has been set in the charging device 200, the current time from the clock circuit 41 is obtained as the charging start time, and this is provided in the EEPROM 154 as charging start history information. Record in charging log file.

When the charging device connection detecting unit 61 notifies that the mobile phone terminal 100 has been separated from the charging device, the control unit 150 obtains the current time from the clock circuit 41 as the charging end time. This is recorded as charge end history information in a charge log file provided in the EEPROM 154.

However, immediately after the mobile phone terminal 100 set in the charging device 200 is set again, or immediately after the mobile phone terminal 100 is set in the charging device 200, the mobile phone terminal 100 is separated from the charging device 200, After using the mobile phone 100 for several minutes,
For example, resetting 0 to the charging device 200,
It often happens that charging is interrupted.

For this reason, when recording the charging start time (charging start history information) in the charging log file, the control unit 150 of the portable telephone terminal 100 of this embodiment stores the charging starting time detected this time and the charging log file. If the difference (time interval) from the latest charging end time recorded in the charging log file is shorter than a predetermined time interval, the charging start time detected this time is recorded in the charging log file as charging start history information. I try not to.

FIG. 3 is a diagram for explaining the charge start time and the charge end time recorded in the charge log file of the EEPROM 154. FIG. 3 is a diagram showing an example of the charging status on each of the past four days, with the horizontal axis representing time for one day (24 hours). In FIG. 3, a strip-shaped portion indicated by oblique lines indicates a time zone in which the mobile phone terminal 100 is set in the charging device 200 and the battery 51 of the mobile phone terminal 100 is being charged.

Therefore, in FIG.
1, M2, S2, and S3 are mobile phone terminals 10 respectively.
0 is detected as the time set in the charging device 200, and at these times, the current time detected by the clock circuit 41 is detected as the charging start time. Further, each of the time points ME1, ME2, E1, and E2 is detected as a time point when the mobile phone terminal 100 is separated from the charging device 200, and at these time points, the current time detected from the clock circuit 41 is set as the charging end time. Is detected.

However, in FIG. 3, the time intervals between the time points ME1 and M1 and between the time points ME2 and M2 are shorter than a predetermined time, for example, several tens of minutes. Therefore, the time points ME1 and ME2 are not regarded as the time points when the charging is completed, but as the time points when the charging is interrupted. Further, the time points M1 and M2 are not regarded as the points in time when the charging is newly started, but as the points in time when the suspended charging is restarted.

Therefore, in FIG. 3, the time point S1 is detected as the charging start time point four days before, and the time point S2 is detected as the charging start point three days ago. Further, the time point S3 is detected as the charging start time point one day ago. Then, the current time detected at these time points S1, S2, and S3 is recorded in the charging history log file of the EEPROM 154 as charging start time, and is used as charging start history information.

In FIG. 3, time point E1 is detected as the end time of the charging started at time point S1 four days ago, and time point E2 is detected as the end time of the charging started at time point S2 three days ago. You. Then, the current time detected at the time points E1 and E2 is recorded in the charge log file of the EEPROM 154 as the charge end time, and is used as charge end history information.

In this manner, the original charge start time is recorded in the charge log file without setting the interrupted charge restart point as the charge start time, and based on the original charge start time, The expected charging start time to be calculated can be calculated accurately and quickly.

As described above, the portable telephone terminal 100 according to the present embodiment is configured such that the time interval between the latest charging end time and the newly detected charging start time is equal to or less than a predetermined time, for example, several minutes. If it is less than tens of minutes, it is determined that the interrupted charging has been resumed, the newly detected charging start time is ignored, and the charging end time corresponding to the charging interruption time recorded in the charging log file is also determined. The original charge start time and the original charge end time are recorded in the charge log file.

As described above, the control unit 150 cooperates with the charging device connection detecting unit 61 to control the EEPROM.
The charge start history information is stored in the charge log file 154. The charge log file of the EEPROM 154 can store charge start history information for the past several days.

FIG. 4 shows a portable telephone terminal 1 according to this embodiment.
FIG. 9 is a diagram for explaining an example of a charge log file formed in the EEPROM 154 at 00. As shown in FIG. 4, in the charging log file of this embodiment, at the time of starting charging, the current date and time at that time from the clock circuit 41 are detected as the starting date and time. This is recorded as the above-described charging start time (charging start history information).

[0098] Based on the detection result, the portable telephone terminal 1
At 00, the required electric energy is accurately estimated, and when the remaining amount of the battery 51 detected by the remaining battery amount detecting unit 71 becomes equal to or less than the estimated required electric energy, recording / recording of music content as an additional function is performed. The use of the playback function is restricted.

More specifically, as shown in FIG.
Based on the charging start history information stored in the charging log file in the ROM 154, a time at which charging is to be performed from the present time (scheduled charging start time) is predicted. Then, the time from the current time to the scheduled charging start time is
At a minimum, this is the expected standby time at which standby reception must be enabled. In other words, the expected standby time is a time indicating how many hours after the present time the telephone function should be used.

Then, for the expected standby time, the amount of electric power necessary for the telephone function to be usable (the amount of electric power necessary for the telephone function) can be expressed by the following equation (1). (Electricity required for telephone function) = (Electricity required for standby) + (Electricity required for telephone call) ... (1)

Here, (the amount of power required for standby) is
It can be obtained as in the following equation (2). That is, (electric power required for standby) = (electric power per minute required for standby) × (expected standby time) (2)

Further, (the amount of power required for a call) can be obtained as in the following equation (3). That is, (power required for a call) = (power per minute required for a call) × (expected call time) (3)

The (power per minute required for standby) in the equation (2) and the (power per minute required for a call) in the equation (3) are defined as terminal-specific values. Since it is known in advance, for example, R
This is recorded in the OM 152.

The (expected standby time) in the equation (2) is the time from the current time to the scheduled charging start time, as described above, and can be obtained by the following equation (4). That is, (estimated standby time) = (scheduled charging start time) − (current time) (4). In this equation (4), (scheduled charging start time)
Is calculated as the average value of the charge start history information stored in the charge log file of the EEPROM 154 for a predetermined period, as described above. Also,
(Current time) is obtained from the clock circuit 41.

The (expected communication time) in the equation (3) can be obtained by the following equation (5). That is, (expected call time) = ((average number of calls per day) × ((scheduled charging start time) − (current time)) / (24 × 60) +1) × (average call time per call) …… (5). Becomes

The equation (5) determines how many more calls are to be made in the mobile phone terminal 100 by the scheduled charging start time, and calculates the average call time for one call for the obtained estimated number of calls. By multiplying, the expected call time of the call made from the current time to the scheduled charging start time is obtained. Note that, in equation (5), +1
Is for enabling at least one call.

Then, as described above, the expected standby time obtained by equation (4) can be used in equation (2), and the amount of power required for performing standby reception (the amount of power required for standby reception) Power). Also, the expected standby talk time calculated by equation (5) is
(Equation (3)) is used to determine (power required for a call) to make a call for the expected call time.

Then, the (power required for standby reception) obtained by the equation (2) and the (power required for speech communication) obtained by the equation (3) are added as shown in the equation (1). Then, the amount of power (the amount of power required for a call) required to keep the telephone function usable for the expected standby time is required.

Next, a specific example of the method of obtaining the scheduled charging start time used in the above equation (4) will be described with reference to the flowchart of FIG. The process of the flowchart shown in FIG. 6 is performed by the charging device connection detecting unit 61 of the mobile phone terminal 100 so that the mobile phone terminal 100
When it is detected that the value is set to 00, the control unit 15
0 is the process executed.

When charging device connection detecting section 61 detects that mobile phone terminal 100 has been set in charging apparatus 200 and notifies control section 150 of this, control section 15 controls control section 15.
In step S101, the current time is detected from the clock circuit 41 (step S101). Then, the control unit 150
Referring to the data recorded in the charge log file of M154, whether a predetermined time T or more has elapsed from the latest charge end time to the current time, in other words, the current time from the latest charge end time to the current time It is determined whether the time up to is equal to or longer than a predetermined time T (step S).
102).

If it is determined in step S102 that the predetermined time period T has not elapsed, as described above, the current setting of the mobile phone terminal 100 into the charging device 200 is performed by resuming the suspended charging. And the current time detected this time is set as the charging start time E
The process shown in FIG. 6 ends without recording the charge log file in the EPROM 154.

If it is determined in step S102 that the predetermined time T has elapsed,
It is determined that charging of the mobile phone terminal 100 to the charging device 200 this time is the start of charging, and the current time detected this time is recorded in the charging log file of the EEPROM 154 as the charging start time (step S103).

Then, the control unit 150 controls the EEPROM 1
The charging start time for the past n days predetermined from the present time is read from the charging log file of No. 54 (step S1).
04), the average of the charging start times obtained in step S104 is obtained, and the obtained average is updated as the charging start time (step S105).

In the portable telephone terminal 100 of this embodiment, the scheduled charging start time obtained as an average value is:
It is updated to a predetermined area of the EEPROM 154. Therefore, a predetermined area in the EEPROM 154 always holds the latest scheduled charging start time. The scheduled charging start time obtained in this manner is used as the (scheduled charging start time) in the above-described equation (4).

Next, a specific example of the method of obtaining the average number of calls used in the above-described equation (5) will be described with reference to the flowchart of FIG. The processing of the flowchart shown in FIG. 7 is performed at regular intervals of a predetermined time, or when a battery content recording function or an additional function, which is an additional function, is used. This is performed in the quantity management process.

In the battery remaining amount management process described later, the control unit 150 calculates the expected call time by using the call start time for the past n days in the data of the call log file in the EEPROM 154 described above with reference to FIG. , The number of calls for the past n days is obtained (step S201).

Next, the control unit 200 calculates the average number of calls per day by dividing the number of calls for the past n days obtained in step S201 by n which is the number of days targeted for the number of calls (step S201). S202). The average number of calls thus determined is temporarily stored in the RAM 153 in the mobile phone terminal 100 of the present embodiment, and is used in the battery remaining amount management process.

Next, a specific example of how to calculate the average call time used in the above-described equation (5) will be described with reference to the flowchart in FIG. The processing of the flowchart shown in FIG. 8 is performed in a similar manner to the calculation of the average number of calls described above with reference to FIG. This is performed in the battery remaining amount management process performed when the function is used.

In the remaining battery level management processing described later, the control unit 150 calculates the expected call time by using the call start time for the past n days in the data of the call log file in the EEPROM 154 described above with reference to FIG. The total of the difference between the call and the call end time is calculated as the total call time (step S301).

Next, in the same manner as the processing of step S201 described above with reference to FIG. 7, the control unit 200 starts the communication for the past n days in the data of the call log file in the EEPROM 154 described above with reference to FIG. The number of calls for the past n days is obtained by counting the time (step S3).
02).

Then, the average call time is calculated by dividing the total call time obtained in step S301 by the number of calls for the past n days obtained in step S302 (step S303). The average call time thus obtained is temporarily stored in the RAM 153 in the mobile phone terminal 100 of this embodiment, and is used in the battery remaining amount management processing.

In this manner, the telephone function can be used for the expected call time by using the history information on the past charge and the history information on the call accumulated in the charge log file and the call log file of the EEPROM 154. It is possible to obtain the scheduled charging start time, the average number of calls per day, and the average talk time per day, which are required when estimating the amount of power required for the above.

Then, the portable telephone terminal 1 of this embodiment
In the case of 00, by managing the remaining amount of the battery, the power for using the telephone function is always secured until the scheduled charging start time. FIG. 9 is a flowchart illustrating a battery remaining amount management process performed in mobile phone terminal 100 according to the present embodiment.

As described above, the processing shown in FIG. 9 is performed by the control unit at regular intervals of a predetermined time or when using a recording function or a reproducing function of a music content which is an additional function. This is the process performed at 150.

That is, the control unit 1 of the portable telephone terminal 100
50, at predetermined time intervals or when an instruction input from a user who instructs to execute the additional function is received, first, recording or reproduction of music content as the additional function is performed. It is determined whether or not it has been performed (step S401).

If it is determined in step S401 that the additional function is not used, the power of the battery 51 is not consumed by the use of the additional function. The processing shown in FIG. 9 ends. Further, in the determination processing of step S401, when it is determined that the additional function is to be used, the control unit 150 controls the battery remaining amount detecting unit 71 to check the remaining amount of the battery 51 (the remaining amount of the battery 51). (Power amount) (step S402).

The control unit 150 performs the processing described with reference to FIGS. 6, 7, and 8 and the expression (1) to the expression (5).
By performing the calculation described using the formula, the amount of power (the amount of power required for a call) necessary to use the telephone function is calculated from the current time to the scheduled charging start time, and this is reserved ( Step S403).

Next, the control unit 150 determines in step S402
The remaining amount of the battery 51 detected in
It is determined whether or not it is larger than the electric energy required for the call as the priority function calculated and reserved in (Step S4)
04). In the determination process of step S404, when it is determined that the remaining amount of the battery 51 is larger than the amount of power required for a call, the current remaining amount of the battery is sufficient.
The processing shown in FIG. 9 ends.

[0129] If it is determined in step S404 that the remaining amount of the battery 51 is not larger than the amount of power necessary for a call, the control unit 150 restricts the use of the additional function. (Step S40
5), the process shown in FIG. 9 ends.

The processing in step S405 is as follows.
Specifically, the use of additional functions is forcibly stopped,
Alternatively, a message is displayed on the LCD 32 that warns that the remaining battery level may be low and the telephone function may not be used until the scheduled charging start time.
In step 2, a low battery icon is lit or blinked to warn the user to stop using the additional function because the remaining battery level is low.

In step S405, a warning sound is emitted through the ringer 33, or the LED 34 is turned on or blinks.
Since the remaining amount of the battery is low, a warning may be issued to stop using the additional function. Further, the user may be warned to stop using the additional function by using all or two of the LCD 32, the ringer 34, and the LED 33.

In the portable telephone terminal 100 of this embodiment, under the control of the control unit 150, “the battery level is low.
Stop recording. Or a message such as "The battery level is low. Stop playing music." On the LCD 32, and the ringer 34 is controlled to emit a warning sound so that the user can use the additional functions. To stop it.

Then, the mobile phone terminal 1 of this embodiment
00 is when the remaining amount of the battery 51 of the mobile phone terminal 100 becomes equal to or less than the amount of power required for the estimated telephone function,
Restrict use of additional functions. As a result, the inconvenience that the telephone function of the mobile phone terminal 100 cannot be used when necessary due to excessive use of the additional function is prevented, and the user can use the additional function with ease.

In addition, restrictions on the use of the additional functions are set at a predetermined point in time, such as the telephone usage status and how long the telephone function should be kept available for use.
Estimate the amount of power required to keep the phone function available for the expected standby time, depending on the state of.

The estimated amount of power is compared with the remaining amount of the battery 51, and based on the result, the additional functions are limited. Therefore, the amount of power required to use the telephone function unnecessarily is reduced. Will not be secured. Accordingly, the use of the additional function is not unnecessarily restricted, and the use of the additional function can be effectively used, so that the use of the telephone function is not hindered.

The mobile phone terminal 10 according to this embodiment
At 0, when it is determined that the remaining amount of the battery 51 is not larger than the amount of power required for a call, a message display and a warning sound may indicate that the remaining amount of the battery does not have the scheduled charging start time. A warning is given and the user is urged to stop using the additional functions.

For this reason, if the user determines that there is no need to make the telephone function available until the time when charging will be performed, that is, the scheduled charging start time, the user stops the additional function. By not performing the operation
The use of the additional function can be continued.

As in the above-described embodiment, it is not necessary to reserve an amount of power sufficient to enable both standby reception and expected communication until the scheduled charging start time.

For example, at regular intervals or when an additional function is used, only the amount of power required for standby reception is calculated based on the above-described equations (2) and (4). Alternatively, the relationship between the remaining amount of the battery 51 and the amount of power required for standby reception may be notified.

In this case, the remaining amount of the battery 51 and the amount of power required for standby reception are displayed on the LCD 32, or when the remaining amount of the battery 51 is larger than the amount of power required for standby reception. Turns on the green LED lighting,
When the remaining amount of the battery 51 becomes equal to or less than the amount of power required for standby reception, the relationship between the remaining amount of the battery 51 and the amount of power required for standby reception is made by turning on a red LED or the like. Notify. Of course, the relationship between the remaining amount of the battery 51 and the amount of power required for standby reception may be notified in other modes.

In step S403 of the flowchart shown in FIG. 9, only the amount of power required for standby reception is calculated based on equations (2) and (4). If it is determined in step S404 that the remaining amount of the battery 51 has become equal to or less than the amount of power required for standby reception, this is determined by the LCD 32, the ringer 33, and the LED3.
The user may be notified or warned through all of 4, or two of them, or one of them, or the additional functions may be restricted.

In this case, if a call is not made from the mobile phone terminal 100, it is possible to know that there is a minimum number of incoming calls. Also, more power can be used for additional functions.

Similarly, at regular intervals or when an additional function is used, only the amount of power required for a call is calculated based on the above-described equations (3) and (5). Then, the relationship between the remaining amount of the battery 51 and the amount of power required for a call may be notified.

In step S403 of the flowchart shown in FIG. 9, only the amount of power required for a call is calculated based on equations (3) and (5). Then, in step S404, when it is determined that the remaining amount of the battery 51 has become equal to or less than the amount of power required for a call, this is determined by the LCD 32, the ringer 33, the LED 34, or two of them, or any of them. The user may be notified or warned through one of the methods, or the additional functions may be restricted.

Even when the additional functions are to be stopped, the user is first notified that the additional functions are to be stopped because the remaining battery power is running low, and the additional functions are stopped after the user inputs a confirmation. Of course, you may make it do. In this case, the recording or reproduction of the music content in the middle of the processing can be performed to a sharp point, and then the additional function can be stopped. Therefore, it is possible to prevent the processing by the additional function from being interrupted halfway.

As described above, the control unit 150 of the mobile phone terminal 100 of this embodiment can know the time from the present time to the time at which charging is to be performed and, at the same time, determine the telephone function of the mobile phone terminal 100. You can know the usage status. The control unit 150 of the mobile phone terminal 100
Is detected by the battery remaining amount detection unit 71 as necessary.
1 can be detected. Also, the power consumption of the mobile phone terminal 100 during standby reception and the power consumption of the mobile phone terminal 100 during a call are known in advance.

For this reason, the control unit 150 of the mobile phone terminal 100 according to the present embodiment predicts the time at which charging will be performed (charging start time) as described above, and from the current time to the charging start time. It is possible to confirm whether or not the electric power required for the battery 51 remains in the battery 51 and notify the user of the result.

Also, by considering the call history information, the number of calls that can be made (the average number of calls) between the present time and the time when charging will be performed.
Or, you can predict the average talk time. For this reason,
It is possible to confirm whether or not the power for the time required for the telephone call that will be performed from the present time to the time when the charging is to be performed is remaining in the battery 51, and notify the user of the result.

In addition, from the present time to the time when charging is to be performed, standby reception is performed, and the mobile phone terminal 100 is used as usual, and it is sufficient to make a call for the same amount of time as usual. Battery 51
It is possible to confirm whether or not it remains, and notify the user of this.

Further, the remaining amount of the battery 51 becomes lower than the electric energy required for performing standby reception and talking for the same amount of time as usual from the current time to the time when charging will be performed. In such a case, it is possible to notify the user of this and to restrict the recording function and the reproducing function of the music content, which are additional functions, to prevent the telephone function from being disabled.

As described above, the mobile phone terminal 100 according to the present embodiment can accurately determine the usage status of the mobile phone terminal 100 and how long the telephone function can be used from the present time. It is possible to estimate the amount of power required for the battery 5 and determine whether the remaining amount of the battery 5 is sufficient or not, notify the user, and limit the use of the additional functions.

Thus, when the remaining power of the battery 5 is not sufficient, the user of the mobile phone terminal 100 of the present embodiment turns off the main power supply of the mobile phone terminal 100 or hangs up. Respond to calls, but do not make calls from the mobile phone terminal 100, or go home early and charge the battery, etc. Becomes possible.

In the above embodiment, the additional functions have been described as the recording function and the reproducing function of the music content. However, it is not limited to this.
For example, additional functions installed in mobile phone terminals include:
It may have a function of recording an image (still image or moving image) by the built-in camera, a function of reproducing an image taken by the built-in camera, a position information display function, a PDA function, and the like. Is also good.

Further, in the above-described embodiment, the scheduled charging start time is predicted based on the information accumulated in the charging log file of the EEPROM 154.

In this case, not only the time but also the scheduled charging start time
The date will also be considered.

In order to determine the scheduled charging start time,
As the data of the charge log file of the EEPROM 154 to be calculated, data of a predetermined number of past days is used, and data older than the predetermined number of days is not used. However, all data recorded in the charging log file may be used for calculating the scheduled charging start time.

Of course, in order to calculate the scheduled charging start time, the number of days to be calculated for the data of the charging log file in the EEPROM 154 may be the number of days necessary for properly determining the scheduled charging start time.

As described above, the scheduled charging start time is obtained as an average value of the charging start times, which are the charging start histories in the charging log file. However, it is not limited to this. For example, of the charge start times recorded in the charge log file, the latest charge start time or the earliest charge start time is used as the scheduled charge start time, or the latest charge start time and the earliest charge The average with the start time may be used as the charge start time.

Further, the number of calls per day and the call time per call were also determined as average values based on the data of the call log file.
It is not limited to this. For example, the number of calls per day is obtained by calculating the number of calls on each past day, and the number of calls on the day with the largest number of calls or on the day with the least number of calls is defined as the number of calls per day. The average value may be used as the number of calls per day.

Also, as for the call time required for one call, for example, the longest call time is detected from the data of the call log file, and this is set as the call time required for one call. The call time may be detected, and this may be used as the call time required for one call. Alternatively, the longest call time and the shortest call time may be detected from the call log file, and the average value thereof may be used as the call time for one call.
