Description

  The present invention relates to a portable data processing device equipped with a rechargeable battery.

  Mobile communication terminal devices (hereinafter abbreviated as “communication terminals”) capable of making phone calls typified by mobile phones and PHS are now widely used in society. In recent years, the communication terminal has been equipped with various functions due to advances in semiconductor technology. As a result, it is now used in a wide range of applications.

  Such a communication terminal is a data processing device that is assumed to be carried and used. In order to make it portable, a rechargeable battery is usually installed. Since it is battery-driven when it is carried, the remaining amount is detected and notified to the user. The remaining amount is usually detected from voltage. Specific detection methods include those described in Patent Documents 1 and 2.

  Most data processing devices equipped with a rechargeable battery can be charged with the battery mounted. Such a data processing apparatus usually has a dedicated charger. Charging with the charger takes a long time, and there are limited places where it can be connected to a power outlet. For this reason, most users usually do not carry the charger. For this reason, many of such data processing devices issue a warning prompting charging or battery replacement when the remaining battery level is low so that it can be used when desired.

  The conventional data processing apparatus gives the warning only paying attention to the remaining amount of the battery. However, the power consumption varies depending on how the user uses it. In the communication terminal, it varies depending on the distance from the base station. Even if the warning is given, since the charger is required for charging the battery, the time at which charging can actually be started varies depending on the location where the charger is located. For these reasons, even if a warning is issued, the remaining amount of the battery often runs out before charging starts depending on how the data processing device is used and how it is carried around. This means that the warning is not necessarily done properly. For this reason, it is considered that the warning of the remaining battery level should be performed in consideration of the usage mode of the data processing device.

By the way, among data processing devices whose power consumption changes due to a change in operational settings, etc., there are some which change the settings according to the remaining battery level to suppress power consumption. Even in such a data processing apparatus, since the power consumption changes depending on the usage pattern, it is considered that the usage pattern should be taken into account even when the setting of the operation content is changed according to the remaining battery level.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
<First Embodiment>
FIG. 1 is a configuration diagram of a data processing apparatus according to the first embodiment. The data processing device 1 is one in which the present invention is applied to a mobile communication terminal device such as a mobile phone or a PHS. Here, for the sake of convenience, it is assumed to be a mobile phone and will be referred to as a “communication terminal”.

  As shown in FIG. 1, the communication terminal 1 controls a radio frequency (RF) unit 101 for a mobile phone that performs frequency conversion, modulation / demodulation, and the like of a radio signal transmitted and received via an antenna AT1, and controls the entire terminal. CPU 102, program ROM 103 storing programs executed by CPU 102 and various control data, work RAM 104 used by CPU 102 for work, two display units 105 and 106, both of which are liquid crystal display devices, for example, and each display unit Display driver unit 107 for displaying images on 105 and 106, microphone 108 for sound input, speaker 109 for sound emission, operation unit 110 having various switches, and AC for receiving current from the outside Adapter 111, rechargeable battery (battery) 112, and power supply circuit for supplying current to each unit And it is configured to include a 13.

  Although not particularly illustrated, an analog audio signal output from the microphone 108 is converted into a digital audio signal by an A / D converter and then output to the CPU 102 or the RF unit 101. In addition, an analog audio signal converted by the D / A converter is output to the speaker 109 and an unillustrated earphone jack.

  The two display units 105 and 106 have different screen sizes. The screen of the display unit 105 is larger. Therefore, the display unit 105 is called a main display unit, and the display unit 106 is called a sub display unit.

  The RF unit 101 receives and processes a signal transmitted from a mobile phone network. The received signal is demodulated and output to the CPU 102, the speaker 109, and a jack (hereinafter, only the former is assumed). At the time of a telephone call, the signal is output to the speaker 109 to emit sound from the connection destination (the telephone connected to the telephone). The audio signal from the microphone 108 is modulated and transmitted via the antenna AT1. When connected to the Internet, the demodulated signal (digital data) is output to the CPU 102. Data from the CPU 102 is modulated and transmitted via the antenna AT1.

The operation unit 115 includes various switches to be operated by the user, and a detection circuit that detects operations performed by the user on the various switches.
The power supply circuit 113 monitors each output of the AC adapter 111 and the rechargeable battery 112. Thereby, it is determined whether or not current is supplied to the AC adapter 111 from an external power source (for example, an outlet), and the CPU 102 is notified of the determination result. The rechargeable battery 112 detects the voltage value and notifies the CPU 102 of it.

  If the user of the communication terminal 1 is a company employee, the user usually makes a round trip between the home 20 and the company 30 as shown in FIG. As a result, when the user is at the office 30, the charger 2 at the home 20 cannot be charged with the communication terminal 1.

  If the company 30 is away from the home 20, it takes a long time to move to the home 20. Naturally, you cannot go home 20 while you are at work. From these things, even if it is warned that the remaining amount of the rechargeable battery 112 of the communication terminal 1 is low when being at the company 30, it takes a very long time to actually start charging. There are many cases.

  This means that there is a high possibility that the communication terminal 1 cannot be used because there is no remaining amount. If it is going to suppress power consumption in order to avoid that happening, use of the communication terminal 1 must be refrained. Therefore, even if charging can be performed before the remaining amount runs out, comfortable use of the communication terminal 1 is hindered. For this reason, in the present embodiment, the timing for warning the remaining amount of the rechargeable battery 112 and the content thereof are changed according to the position (location) where the communication terminal 1 exists. As a result, if the communication terminal 1 exists in a place where charging cannot be started relatively quickly, a warning is given earlier than when the communication terminal 1 exists in a place where charging can start relatively quickly, thereby hindering comfortable use. So that you can avoid things like that.

  As is well known, the base station 10 transmits its own location information at any time because the communication terminal 1 needs to perform location registration. The location is recognized by using the base station 10 unit. Accordingly, as shown in FIG. 2, for example, if communication can be made with the base station AA10 at home 20, the place where communication with the base station AA can be recognized as a place where charging can be started relatively quickly, and otherwise , That is, a place where communication with any of the base stations 10 marked with A to C, Y, and Z is recognized as a place where charging cannot be started relatively early.

  Hereinafter, the operation of the communication terminal configured as described above will be described in detail with reference to the flowcharts of the processes shown in FIGS. Each process illustrated in FIGS. 3 to 8 is realized by the CPU 102 executing a program stored in the program ROM 103, for example.

  FIG. 3 is a flowchart of the entire process. It shows an excerpt of the overall flow of processing executed after the power is turned on. First, the entire process will be described in detail with reference to FIG.

  First, in step 301, initialization is executed when the power is turned on, and the communication terminal is set to a predetermined setting state. In the subsequent step 302, the position information transmitted from the communicable base station 10 is received, and the position information is stored in the work RAM 104 as a base station number (NO.). Thereafter, the process proceeds to step 303.

  The location information (base station number) is information used for determining whether or not the communication terminal 1 should perform location registration. The location registration is performed when the reception level is lowered to some extent or when different location information is received.

  In step 303, for example, the standby screen read from the program ROM 108 is stored in the drawing area secured in the work RAM 104, and the screen is sent to the display driver unit 107 and displayed on the main display unit 105. Similarly, the sub display unit 106 displays a standby screen. In the next step 304, it is determined whether or not charging is in progress. When it is notified from the power supply circuit 113 that the battery is being charged, the determination is YES, the process returns to step 303, and the standby display state is maintained on the main display unit 105. Otherwise, the determination is no and the process moves to step 305.

  The base station number received from the base station 10 during charging is stored separately in a charging base station number (NO.) Memory (hereinafter referred to as “number memory”) which is an area secured in the work RAM 104. Yes. In step 305, the number memory is searched using the base station number currently received from the base station 10 (hereinafter referred to as “acquired base station number” to avoid confusion). In the next step 306, the voltage value of the rechargeable battery 112 acquired from the power supply circuit 113 stored in the battery voltage memory that is an area secured in the work RAM 104 is substituted for the variable V. In step 307 to be transferred thereafter, it is determined whether or not the acquired base station number can be extracted from the base station numbers stored in the number memory by the search performed in step 305. If the acquired base station number is not stored in the number memory, the determination is no and the process moves to step 311, and if not, the determination is yes and the process moves to step 308.

  In step 308, it is determined whether or not a value (= Ev−α) obtained by subtracting the predetermined value α from the threshold value Ev set as the warning level of the remaining battery level 112 is equal to or greater than the value of the variable V. If the value of the variable V is equal to or less than that value, the determination is YES, and the remaining amount of the rechargeable battery 112 is assumed to be a level that prompts charging. After being displayed on the sections 105 and 106, the process returns to step 303. On the other hand, if this is not the case, that is, if the value of the variable V is larger than that value, the determination is NO, and the display A mark is erased in step 310, assuming that the remaining amount of the rechargeable battery 112 is not at a level prompting charging. Then, the process returns to step 303. In these steps 309 and 310, when it is necessary to newly display or erase the mark, the mark is displayed or erased. The same applies to other cases. The threshold value Ev and the predetermined value α are data stored as control data in the program ROM 103.

  The screen displayed on each of the display units 105 and 106 stores image data (screen, symbols, etc.) read from the program ROM 103 or image data sent from the RF unit 101 in a drawing area secured in the work RAM 104. Is generated. The change of the display contents is realized by sending all or part of the display contents to the display driver unit 107 and displaying them.

  On the other hand, in step 311, it is determined whether or not the threshold value Ev is greater than or equal to the value of the variable V. If the value of the variable V is equal to or less than the threshold value Ev, the determination is YES, and it is determined that the remaining amount of the rechargeable battery 112 is a level that should be strongly warned. After being displayed on the display units 105 and 106, the process returns to step 303. On the other hand, if not, that is, if the value of the variable V is larger than the threshold value Ev, the determination is NO, and the remaining charge of the rechargeable battery 112 is not at that level. Return to step 303.

  In this way, in the present embodiment, if the location where the communication terminal 1 is located is not within the communication range of the base station 10 that has charged the rechargeable battery 112, the location is within the communication range. Thus, charging is more strongly urged to the user at a level where the remaining amount is higher. As a result, for the user, charging is prompted at a timing according to the location (position) where the communication terminal 1 exists, so it is sure that the situation will be such that the remaining amount runs out and cannot be used without refraining from using it. Can be avoided. As a result, the communication terminal 1 can be used more comfortably.

  FIG. 4 is a flowchart of the off-hook switch process. The switch process is for dealing with a case where a user makes a telephone call by inputting a telephone number after operating an off-hook switch. For example, it is executed as a subroutine process in an interrupt process for responding to a user operation on the operation unit 110. Next, the off-hook switch process will be described in detail with reference to FIG. Note that each of the processes shown in the flowcharts in FIGS. 5 to 8 is an interrupt process.

  First, in step 401, a number input screen for inputting a telephone number is displayed on the main display unit 105. In the next step 402, it is determined whether or not a number input operation (operation on the dial key) on the operation unit 110 has been performed. If the user performs the input operation, the operation unit 110 notifies that fact, so the determination is YES, and after the number input by the input operation is displayed in the number input screen in step 403, the step Go to 404. Otherwise, the determination is no and the process moves to step 404.

  In step 404, it is determined whether or not a fixed time has elapsed since the last input operation. If the fixed time has elapsed, the determination is yes and the process proceeds to step 406, where the user connects to a telephone having a designated telephone number (hereinafter referred to as "connection destination" or "partner machine"). Make the requested call. Otherwise, the determination is no and the process moves to step 405 to determine whether or not the on-hook switch is turned on. If the switch is operated by the user, the determination is yes, and the standby screen is displayed on the main display unit 105, and then the series of processing ends. Otherwise, the determination is no and the process returns to step 402 above.

  By the above transmission, the mobile phone network side performs a process for calling the designated partner machine, and the calling side performs a process for emitting a ringing sound to notify that. Therefore, in step 407 following step 406, a ringing tone is emitted in accordance with an instruction from the mobile phone network side. The sound emission is performed until the determination in the next step 408 becomes YES by connecting to the partner machine. The process proceeds to step 409 with a YES determination.

  Note that the above transmission is performed, for example, when the CPU 102 sends necessary information to the RF unit 101 and instructs it. The ringing tone is emitted when the RF signal is received by the RF unit 101 and demodulated, and the demodulated signal is output to the speaker 109 directly or via the CPU 102.

  If the other party is busy or the telephone cannot be placed because the power is off, a signal to that effect is transmitted from the mobile phone network side. The call of the other party is terminated when the user instructs to stop the transmission. For this reason, it is not always possible to connect to the other device by making an outgoing call. However, since this is not particularly important, it is omitted here. The same applies to other cases.

  In step 409, call processing for realizing a call by exchanging audio signals with the other party is executed. In the next step 410, it is determined whether or not the on-hook switch is turned on. If the switch is operated by the user, the determination is yes, and after disconnecting the connection with the other device, that is, in the step 411, the end-call processing for requesting the end-call to the mobile phone network side is executed, and then the series of processing ends. . Otherwise, the determination is no and the process returns to step 409. As a result, a state in which a call can be made is maintained until the end of the call is requested.

  FIG. 5 is a flowchart of incoming call detection processing. The detection process is executed to respond to an incoming call. For example, it is activated by an interrupt signal generated by the RF unit 101 that detects the incoming call. Next, the detection process will be described in detail with reference to FIG.

  First, in step 501, voice data for emitting a ringtone is read from, for example, the program ROM 103 and output to the speaker 109 to emit the ringtone, and the main display unit 105 is notified of an incoming call, for example. Is displayed. In the next step 502, it is determined whether or not the off-hook switch is turned on. If the user operates the switch, the determination is yes and the process proceeds to step 503. If not, the determination is no and the process returns to step 501. Accordingly, the incoming call notification is continued.

  In step 503, the incoming call notification is stopped, and an icon for notifying that a call is in progress is displayed on the main display unit 105. In the following step 504, a call process for realizing a call with the partner machine is executed. In step 505 which moves to after that, it is determined whether or not the on-hook switch is turned on. If the user operates the on-hook switch, the determination is yes, and in step 506, the end-of-call process is executed to disconnect the connection, and the series of processes ends. Otherwise, the determination is no and the process returns to step 504. As a result, a state in which a call can be made is maintained, and the call time displayed on the main display unit 105 is updated.

  By executing the above call processing, the audio signal (data) demodulated and output by the RF unit 101 is sent to the speaker 109 and is input from the microphone 108 (digital signal after A / D conversion). Is sent to the RF unit 101 for transmission.

  FIG. 6 is a flowchart of the charge-on process. The ON process is activated by an interrupt signal generated by the power supply circuit 113 that detects the start of supply of current from the AC adapter 111, that is, the start of charging of the rechargeable battery 112. Next, the ON process will be described in detail with reference to FIG.

  First, in step 601, it is determined whether or not the acquired base station number is stored in the number memory. If the base station number is stored in the number memory, the determination is no and the series of processing ends here. Otherwise, the determination is yes, and after the base station number is stored in the number memory in step 602, the series of processing is terminated.

  In this way, the base station number received at the time of charging is stored in the number memory. Thereby, it is possible to determine whether or not the base station 10 is in a communication area where charging is possible.

  The base station number transmitted by the base station 10 is obtained by executing the timer interrupt 1 process shown in FIG. In step 701 executed by the interrupt 1 process, the RF unit 101 is driven and the base station number received by the RF unit 101 is stored in the work RAM 104.

  The voltage value of the rechargeable battery 112 is acquired by executing the timer interrupt 2 process shown in FIG. In the interrupt 2 process, the voltage value of the rechargeable battery 112 is acquired from the power supply circuit 113 in step 801, and the voltage value is stored in the battery voltage memory which is an area secured in the work RAM 104 in the next step 802. Yes. In step 306 of FIG. 3, the voltage value thus stored in the battery voltage memory is substituted into the variable V. Both the timer interrupt 2 process and the timer interrupt 1 process are activated by, for example, an interrupt signal generated by a timer mounted on the CPU 102 at regular intervals.

Note that in the first embodiment, depending on whether or not the base station 10 that has been charged is within the communication range, not only the remaining battery level for warning the rechargeable battery 112 but also the warning content is changed. However, the content may be the same.
<Second Embodiment>
In the first embodiment, the remaining battery level for warning the rechargeable battery 112 is switched depending on whether or not the base station 10 that has been charged is within the communication range. In the second embodiment, the remaining battery level for warning the rechargeable battery 112 is changed according to the base station 10 even within the communication range of the base station 10 that has been charged. .

  The user of the communication terminal 1 carries the charger 2 or charges a plurality of places by preparing a plurality of chargers 2. However, the frequency of using the communication terminal 1 at each location is considered to be different. For example, a user who charges at home 20 and company 30 must refrain from using a private telephone while working, so it can be said that company 30 is usually less frequently used. For this reason, even within the communication range of the base station 10 that has been charged, by changing the remaining battery level for performing the warning of the rechargeable battery 112 according to the base station 10, it is possible to perform at a more appropriate timing. A warning can be made.

  The configuration of the communication terminal 1 in the second embodiment is basically the same as that in the first embodiment, and the operation is partially different from that in the first embodiment. For this reason, the same or basically the same components as those of the first embodiment are denoted by the same reference numerals, and only operations different from those of the first embodiment are shown in FIGS. This will be described in detail with reference to the flowcharts of the processes shown.

  9 and 10 are flowcharts of the entire process. First, the overall processing in the second embodiment will be described in detail with reference to FIGS. 9 and 10. Here, the processing steps that are not different from those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and only the portions that are different from the first embodiment are described. The same applies to other cases.

  In the second embodiment, when the determination in step 307 is YES, the process proceeds to step 901 in FIG. In step 901, the current time (current time) is acquired from, for example, a built-in timer. In the subsequent step 902, a value representing the current time in units of one hour is substituted for the variable x. The value corresponds to what hour and what hour, and is represented as “hour” in the figure. Hereinafter, the notation is used in that sense.

  In step 903, which moves to step 902, the acquired base station number is substituted for variable y. In the next step 904, the subarea designated by the values of the variables x and y in the area H secured in the work RAM 104 (“H (x) (y)” in the figure. The value corresponding to the read value (“TABLE {H (x) (y)” in the figure is referred to) by referring to the TABLE that defines the relationship between the value and the value to be substituted for the variable α. } ”. The following notation is used) is substituted into the variable α. Step 308 then proceeds.

  The area H is an area prepared for storing the number of calls made hourly for each base station 10 charged in the communication area. TABLE is control data stored in the program ROM 103 in which the relationship between the number of times and the value to be set as the predetermined value α in the first embodiment is defined. Accordingly, in the second embodiment, attention is paid to the number of calls as the usage frequency of the communication terminal 1, and the remaining level to be warned is changed for each base station 10 according to the number of calls corresponding to the current time. Yes. By reflecting the usage frequency in the remaining amount level for warning in this way, warning can be given at a more appropriate timing.

The change of the remaining amount level as described above, that is, the change of the value assigned to the variable α is realized as follows.
In the off-hook switch process, as shown in FIG. 11, after the call termination process is executed in step 411, the recording process is executed in step 1101, and then the series of processes is terminated. Similarly, in the incoming call detection process, although not specifically shown, after the call termination process is executed in step 506 shown in FIG. 5, the recording process is executed and then the series of processes is terminated. Next, the recording process will be described in detail with reference to the flowchart shown in FIG.

  In the recording process, first, in step 1201, it is determined whether or not the acquired base station number is stored in the number memory. If the communication terminal 1 currently exists within the communication range of the base station 10 that has been charged, the acquired base station number is stored in the number memory, so the determination is YES and the process proceeds to step 1202 Otherwise, the determination is no and the series of processing ends here.

  In step 1202, the current time is acquired. In the next step 1203, a value indicating the current time is substituted for the variable x, and the acquired base station number is substituted for the variable y. In the next step 1204, a subarea (“M (x) (y)” in the figure) designated by the values of the variables x and y in the area M secured in the work RAM 104 is used. ) Is incremented. Thereafter, the series of processing is terminated.

  Thus, the area M is prepared for counting the number of calls for each base station 10 at the time when the call is made. The number of calls saved in area H is calculated using the value stored in area M.

  The sub-areas for each base station 10 in the area M are secured by executing the charge-on process. Next, with reference to the flowchart shown in FIG. 13, the charge-on process in 2nd Embodiment is demonstrated in detail.

  First, in step 1301, it is determined whether or not the acquired base station number is stored in the number memory. If the base station number is stored in the number memory, the determination is no and the series of processing ends here. Otherwise, the determination is yes and the process moves to step 1302.

  In step 1302, the obtained base station number is substituted for variable y. In the subsequent step 1303, in order to count the number of calls according to time, a total of 24 subareas of subareas M (0) (y) to (23) (y) are secured in the area M. In the next step 1304, 0 is stored in each of the newly secured subareas M (0) (y) to (23) (y). Thereafter, after the acquired base station number is stored in the number memory in step 1305, a series of processing is terminated.

  In this way, when charging is performed within the communication range of the base station 10 that has not been charged, a sub-area for the base station 10 is newly secured in the area M. Thereby, the number of calls using the area M is counted.

  The number of calls to area H is stored by executing the timer interrupt 3 process shown in FIG. Finally, the interrupt 3 process will be described in detail with reference to the flowchart shown in FIG. The interrupt 3 process is activated by an interrupt signal generated by a timer at a time interval of one week, for example.

  First, in step 1401, one base station number is read from the number memory. In the next step 1402, the number is substituted into the variable y. Thereafter, in step 1403, 0 is substituted for variable x, and in the next step 1404, the value obtained by dividing the value of subarea M (x) (y) by 7 is stored in subarea H (x) (y). Further, after substituting the value of the variable x in step 1405, the process proceeds to step 1406.

  In step 1406, it is determined whether or not the value of the variable x is greater than 23. After storing the number of calls in all the sub-areas H (x) (y) corresponding to the base station number read out in step 1401, 24 is substituted into the variable x. For this reason, when the storage of the number of calls is completed, the determination is YES, and the process proceeds to step 1407. Otherwise, the determination is no and the process returns to step 1405. Thereby, storing of the number of calls is continued.

  In step 1407, it is determined whether there is another base station number that does not store the number of calls in the number memory. If such a base station number remains, the determination is yes and the process returns to step 1401 to read the remaining base station number. If this is not the case, that is, if the number of calls has been stored for all base station numbers, the determination is no, and after clearing all the values stored in area M in step 1408, a series of processing is performed. finish.

  Thus, in the second embodiment, the number of calls stored in the area H is updated every week. The number of calls stored by the update is an average number of calls per day obtained by dividing the number of calls per week by seven. This avoids the effects of changes in the number of daily calls.

In the second embodiment, the value (change amount of the remaining amount level) to be substituted for the variable α is determined using the average number of calls per day obtained in one week, but the number of calls depends on the day of the week. Since the time period during which calls are frequently made may be different, the average number of calls may be obtained for each day of the week.
<Third Embodiment>
In the second embodiment, the remaining battery level for warning the rechargeable battery 112 is changed according to the base station 10 even within the communication range of the base station 10 that has been charged. On the other hand, in the third embodiment, the setting change is automatically performed so as to further suppress the power consumption according to the remaining amount level if it is not within the communication range.

  By further reducing the power consumption, it is possible to extend the time from when the remaining amount of the rechargeable battery 112 drops to a warning level until it disappears. For this reason, after the remaining amount of the rechargeable battery 112 is reduced to that level, the communication terminal 1 can be used for a longer time. Thereby, the user can use the communication terminal 1 more comfortably as compared with the first and second embodiments.

  The configuration of the communication terminal 1 in the third embodiment is basically the same as that in the first embodiment, as in the second embodiment. The operation is partially different from that of the second embodiment. For this reason, the same or basically the same components as those of the first embodiment are denoted by the same reference numerals, and only operations different from those of the second embodiment are shown in FIGS. Details will be described with reference to flowcharts of the respective processes.

  15 and 16 are flowcharts of the entire process. First, the overall processing in the third embodiment will be described in detail with reference to FIGS. 15 and 16. Here, among the processing steps given the same reference numerals as those of the second embodiment, those whose contents are not different from those of the second embodiment are omitted from the description of the second embodiment. Only the differences will be described. The same applies to other cases.

  In the third embodiment, when the determination in step 307 is YES, the process proceeds to step 901 in FIG. 10 and the subsequent processing is executed in the same manner as in the second embodiment. On the other hand, if the determination is NO, the process proceeds to step 1501 in FIG.

  In step 1501, it is determined whether or not the threshold value Ev is equal to or greater than the value of the variable V. If the remaining battery level of the rechargeable battery 112 is greater than the level indicated by the threshold value Ev, the determination is no and the process moves to step 1510. Otherwise, the determination is yes and the process moves to step 1502.

  In step 1502, the current time is acquired. In the subsequent step 1503, a value indicating the current time is substituted for the variable x. In step 1504 that moves to the subsequent step, it is determined whether or not the value of the element OFF (x) designated by the value of the variable x of the array variable OFF is larger than the threshold value β. If the value of the element OFF (x) is larger than the threshold value β, the determination is YES and the process proceeds to step 1505. Otherwise, the determination is NO and the process proceeds to step 1507.

  The user's action range is not all covered by the base station 10. There is an out-of-communication area where communication with any base station 10 is not possible. There may also be users who often act outside the communication range for reasons such as leisure or work mobility. For this reason, in the third embodiment, as the usage mode of the communication terminal 1, the user's behavior outside the communication range is considered.

  The consideration is that, like the number of calls, the time spent outside the communication range is counted by time, the value indicating the ratio of being outside the communication range is obtained from past actions, and the calculated value is reflected in the operational settings. Is going on. The array variable OFF is prepared for storing the value according to time. The threshold value β is prepared as control data in order to determine whether or not to change the operation setting. Here, the target of the setting change is on / off of driving of the RF unit 101. This is because the power consumption of the RF unit 101 is relatively large. For this reason, the determination of YES in step 1504 means that it is determined that the RF unit 101 should be turned off.

  In step 1505, in which the determination in step 1504 is YES and the process proceeds to step 1505, it is determined whether or not the RF unit 101 (indicated as “communication unit” in the figure) is on. If the RF unit 101 is on, the determination is yes, and after turning it off in step 1506, the process returns to step 303 in FIG. Otherwise, the determination is no and the process returns to step 303.

  In this way, in the third embodiment, it is said that the ratio of staying outside the communication range from the past behavior is a relatively high time zone and is not within the communication range of the base station 10 that has been charged. When the remaining level of the rechargeable battery 112 is lowered to some extent under the circumstances, the RF unit 101 is turned off to keep the rechargeable battery 112 longer.

  In step 1507 where the determination in step 1504 is NO and the process proceeds, it is determined whether or not the RF unit 101 is off. If the RF unit 101 is off, the determination is yes, turning it on at step 1508, and further setting the reception period of the RF unit 101 to double the normal at step 1509, and then step 303 of FIG. Return to. Otherwise, the determination is no and the process moves to step 1509.

  By setting the reception period to twice the normal period, power consumption can be further suppressed. In the third embodiment, it is satisfied in the situation where the ratio of being out of the communication range from the past behavior is not relatively high and the communication range of the base station 10 that has been charged is not. When the remaining level of the battery 112 is lowered to some extent, the setting of the reception cycle is changed so that the rechargeable battery 112 is held longer. By setting the reception cycle to twice the normal, the reception cycle of the base station number is also doubled. Therefore, the interrupt cycle of the timer interrupt 1 process is also changed according to the reception cycle.

  In step 1510 where the determination in step 1501 is NO and the process proceeds, it is determined whether or not the RF unit 101 is off. If the RF unit 101 is off, the determination is YES, turn it on at step 1511, set the reception cycle of the RF unit 101 to normal at step 1512, and then go to step 303 in FIG. Return. Otherwise, the determination is no and the process moves to step 1512.

  Although not particularly illustrated, even in the third embodiment, a warning corresponding to the remaining level of the rechargeable battery 112 in a situation where the base station 10 that has been charged does not exist within the communication range Is also conducted. If the remaining amount level is equal to or lower than the threshold value β, the RF unit 101 is turned off depending on the situation. However, another threshold value smaller than the threshold value β is set, and the RF is set on condition that the threshold value is lower than the other threshold value. The part 101 may be turned off.

FIG. 17 is a flowchart of the recording process. Next, a recording process in the third embodiment will be described in detail with reference to FIG.
In the second embodiment, the number of calls is stored in the area M for each base station 10 that has been charged in the communication range. On the other hand, in the third embodiment, the number of calls is stored hourly for each base station 10 without making such a distinction. The recording process has been changed to accommodate it.

  First, in step 1701, the current time is acquired. In the next step 1702, a value indicating the current time is substituted for the variable x, and in the next step 1703, the acquired base station number is substituted for the variable y. Step 1704 then proceeds.

  In step 1704, it is determined whether or not the sub area M (x) (y) designated by the values of the variables x and y is secured in the area M. If it is not secured, the determination is yes, and after securing it in step 1705 and storing 0, the series of processing ends. Otherwise, the determination is no and the series of processing ends here.

  The process of calculating and storing the number of calls (average value) stored in area H from the number of calls stored in area M is performed by the timer interrupt 3 process. In the third embodiment, since the number of calls is stored in the area M regardless of whether the base station 10 is charged in the communication area, the timer interrupt 3 process is also made compatible with it. As a result, the average value of the number of calls for all subareas in area M is obtained and stored in the corresponding subarea in area H.

FIG. 18 is a flowchart of the timer interrupt 1 process. Next, with reference to FIG. 18, the interrupt 1 process in the third embodiment will be described in detail.
First, in step 1801, a request is made to the RF unit 101 to acquire a base station number. In the following step 1802, it is determined whether or not the base station number has been acquired by the request. If the communication terminal 1 exists within the communication range of any of the base stations 10, the number can be acquired. Therefore, the determination is YES, and after the number is stored in the work RAM 104 in step 1803, a series of processing ends. To do. Otherwise, the determination is no and the process moves to step 1804.

  In step 1804, the current time is acquired. In the next step 1805, a value indicating the current time is substituted for the variable x. In the next step 1806, there is no sub-area (denoted as “K (x)” in the figure. The notation is used hereinafter) in the area K secured in the work RAM 104. It is determined whether or not. If the sub-area K (x) does not exist, the determination is YES, and after securing it in the area K in step 1807 and storing 0, and further incrementing the value of the sub-area K (x) in step 1808 Then, a series of processing is completed. Otherwise, the determination is no and the process moves to step 1808.

  As described above, the value of the sub area K (x) is incremented every time the timer interrupt 1 process is executed while the value is outside the communication range. The interrupt 1 process is started at the set interrupt cycle. For this reason, the value of the sub-area K (x) indicates the time spent outside the communication area in the corresponding time zone. Note that since the interrupt period is changed in accordance with the reception period set in the RF unit 101, the updating method of the value of the sub area K (x) is changed according to the interrupt period, although not particularly illustrated. ing.

  FIG. 19 is a flowchart of the timer interrupt 4 process. Similar to the timer interrupt 3 process, the interrupt 4 process is started by an interrupt signal generated by a timer at a time interval of one week, for example. Finally, the interrupt 4 process will be described in detail with reference to FIG.

  The interrupt 4 process is executed to update the value assigned to each element of the array variable OFF. In the sub-area of the area K, a value indicating the time spent outside the communication range is stored according to time. In the third embodiment, a value indicating the average time per day is obtained hourly from the value indicating the time, and the value is substituted into the corresponding element of the array variable OFF. Instead of the average time, a ratio of the average time to the whole may be substituted.

  First, in step 1901, 0 is substituted for the variable x. In the subsequent step 1902, the value obtained by dividing the value of the sub-area K (x) designated by the value of the variable x in the area K by 7 to the element OFF (x) designated by the value of the variable x of the array variable OFF. (The average time per day in the time zone corresponding to the value of the variable x was outside the communication range) is substituted. Thereafter, in step 1903, the value of the variable x is incremented, and then the process proceeds to step 1904.

  In step 1904, it is determined whether or not the value of the variable x is greater than 23. If the value is greater than 23, the determination is YES, and after all values stored in area K are cleared in step 1905, the assignment of values to each element OFF (0) to (23) is completed. A series of processing ends. Otherwise, the determination is no and the process returns to step 1902 above. Thereby, updating of the value assigned to the element of the array variable OFF is continued.

  In the third embodiment, the remaining battery level warning in the communication area of the base station 10 that is not being charged is not related to the base station 10 in the communication area when the remaining battery level of the rechargeable battery 112 falls below the threshold value Ev. However, the remaining amount level for warning may be changed in consideration of the base station 10. As a method for determining the amount of change, a method may be adopted in which the value to be substituted for the variable α is different depending on the base station 10 when the base station 10 that has been charged is within the communication range.

  In the present embodiment (first to third embodiments), the position (location) is recognized from the base station 10, but the position may be recognized using another method. For example, the position may be recognized using GPS, or the position may be recognized in a binary manner by paying attention to whether or not communication with another wireless communication network can be performed. As another wireless communication network, for example, a wireless LAN constructed at home 20 or company 30, a wireless communication network constructed for Internet connection service, and the like are conceivable. For this reason, the present invention can be widely applied to data processing apparatuses other than the communication terminal 1. Since there may be a user who places the charger 2 in the car, the user who changes the base station 10 in the communication area during charging should not reflect the position recognition result on the remaining amount warning of the charger 112. Also good.

  A program for realizing the communication terminal (data processing device) 1 as described above may be distributed by being recorded on a recording medium such as a CD-ROM, a DVD, or a removable flash memory. Part or all of the program may be distributed via a communication network such as a cellular phone network or a public network. In such a case, the user can apply the present invention to the data processing apparatus by acquiring the program and loading it into the data processing apparatus. For this reason, the recording medium may be accessible by a device that distributes the program.
