[Prior art]
2. Description of the Related Art With the spread of mobile terminal devices, the era has come in which individuals have mobile phones. Since the mobile phone is used for wireless communication, it is necessary for the mobile terminal device to make an incoming call determination to the base station at a fixed time interval from the terminal itself to the base station.
[0003]
For this reason, the portable terminal device has an intermittent control function, enters a sleep state for a predetermined time interval, and turns off the power of the non-functional LSI. Then, after a lapse of a predetermined time, the LSI is powered on, the process is started, and the incoming call is determined. If there is no incoming call, it goes to sleep again. Thereafter, the same operation is repeated.
[0004]
On the other hand, if there is an incoming call to the own terminal, the control shifts to a receiving process after the incoming call determination.
[0005]
In the above case, the intermittent control function in the portable terminal device operates even in a time zone where there is no incoming call, such as at night, or in a time zone where it is not used at all.
[0006]

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0018]
First, the overall configuration will be described with reference to FIG. FIG. 1 is an overall block diagram showing an embodiment of the present invention. It comprises a CPU 11, a power ON / OFF circuit 12 for performing power ON / OFF control, a control circuit 13 for performing intermittent control, a baseband LSI 14, a radio unit TRX15, an antenna 16, a buffer 17, and a POWER control circuit 18. The CPU 11, the power ON / OFF circuit 12, and the control circuit 13 are responsible for intermittent control of the baseband LSI 14, the radio unit TRX15, and the power control circuit 18.
[0019]
The CPU 11 controls the power ON / OFF circuit 12 and the control circuit 13 by software. Then, the control circuit 13 intermittently controls the baseband LSI 14, the radio unit TRX15, and the POWER control circuit 18. The power ON / OFF circuit 12 turns ON / OFF the intermittent control. In the buffer 17, a control program is saved.
[0020]
FIG. 2 is a configuration diagram of the power ON / OFF circuit 12. The timer X24 is a timer that counts the current time. The register X21 is a register in which the time at which the power is turned off is saved. The comparator X22 compares the two, and outputs a signal at the same time, operates the interval circuit 23 and disables the control circuit 13 at the subsequent stage.
[0021]
The register Y26 is a register in which the time at which the power is turned on is saved. The comparator Y25 compares the two, and outputs a signal at the same time, stops the interval operation of the interval circuit 23, and starts the control circuit 13 at the subsequent stage.
[0022]
The interval circuit 23 has a function of turning off the power for a certain time and a function of turning on the power for a certain time.
[0023]
The table 27 serves as a reference for setting the time for operating the interval circuit 23. In this table 27, the power-off time or the power-on time set by the user himself is saved. In addition, the time at which the power is turned off or the time at which the power is turned on is saved according to the result determined from the incoming call determination of the user described later.
[0024]
FIG. 3 is a diagram illustrating a configuration of the control circuit 13. The control circuit 13 includes timers B31 and C34. The stop time (sleep time) and the start time are counted by these two timers, respectively. The timer B31 and the timer C34 operate sequentially.
[0025]
That is, the comparison with the register B32 is performed by the comparator B33 while the timer B31 is operating, and the timer C34 is started after the comparison. The comparison with the register C35 is performed by the comparator C36 while the timer C34 is operating, and a control pulse is output after the comparison.
[0026]
By mounting a plurality of combinations of the register C35 and the comparator C36, a plurality of control pulses can be output. That is, it is only necessary to increase the number of registers and comparators for the types of necessary signals.
[0027]
FIG. 4 is a flowchart showing a procedure for totalizing the incoming call histories. In a normal portable terminal device, the incoming call determination process is repeated while the user does not operate anything. Intermittent control is used for this incoming call determination. The intermittent control includes a sleep time and an incoming call processing time. For the incoming call processing time, an LSI mounted in the portable terminal device is activated, a signal from the base station is received, and it is determined whether there is an incoming call to the own portable terminal device.
[0028]
On the other hand, the sleep time refers to a time period in which only the necessary minimum devices operate and devices that do not need to operate at present are in a stopped state. It is determined whether there is an incoming call in the incoming call determination in which the processing is repeated in the intermittent control.
[0029]
If there is no incoming call (S101 / NO), the incoming call determination is repeated at regular time intervals. If there is an incoming call determination (S101 / YES), the process proceeds to incoming call processing thereafter, but before that, an incoming call history is recorded (S102). Then, before the incoming call processing, the count value of the time table is counted up from the current time information (S103). Then, the distinction between the presence and absence of the incoming call is totaled for each unit time. Here, the time zone without the incoming call determination is related to the set time of the ON / OFF control circuit of the control circuit described later.
[0030]
FIG. 5 is a table for setting the timer time of the ON / OFF control, and shows an example of a table for calculating the incoming call history for each time period. As shown in FIG. 5, the incoming call history is recorded every hour. The incoming call history is recorded according to the flow shown in FIG. Then, for each time zone, it is determined whether there is an incoming call or not. If there is an incoming call at this table, no special action is taken. If there is a time zone in which there is no incoming call determination, the time for turning off the power in the register X21 and the time for turning on the power in the register Y20 are set from the table 27 described above.
[0031]
The case shown in FIG. 5 is a table showing a tabulation table when there is no incoming call from 1:00 am to 6:00 am FIG. 5 shows an example of the setting. That is, according to the function of the terminal model, a more detailed control can be performed by shortening the method of counting the incoming call history, for example, every 30 minutes.
[0032]
The portable terminal device of the present invention always counts the incoming call history. Then, the history is totaled for each determined time zone, and it is determined whether or not there is an incoming call. From this result, it becomes possible to automatically turn off the portable terminal device when the time zone comes, and to turn on the portable terminal device when the time comes. To operate these functions, a clock function is required. However, since the portable terminal device of the present invention has a clock function, the clock function is used to cultivate table data, ON / OFF control can be performed. However, this does not apply when the other party is called by himself or an interrupt is received from another LSI.
[0033]
FIG. 6 is a timing chart showing the overall operation. A signal output from the ON / OFF control circuit is a control signal. With this control signal, the control circuit of the next stage operates or stops. The control signal turns on the power or turns off the power.
[0034]
Here, as shown in FIG. 5, a timing chart in the case where control is performed based on the result of totalizing and determining the user's incoming call history is shown. That is, at 1:00 am according to the result of the table, the control signal output from the ON / OFF control circuit becomes inactive, and the control circuit is stopped.
[0035]
At this time, the intermittent control also stops at the same time. At 6:00 am, the control signal output from the ON / OFF control circuit becomes active, the control circuit is operated, and the operation of the intermittent control circuit is restarted.
[0036]
【The invention's effect】
