BACKGROUND OF THE INVENTION
The present invention relates to a portable terminal configured such that a timer value indicating a pause time of operation of application software is set in a library, and a control unit can perform a low power consumption operation with a lower power consumption than a normal operation, and The present invention relates to a computer program executed on the portable terminal.
[0002]
[Problems to be solved by the invention]
In recent years, mobile phones that can operate an unspecified number of application software such as game software (software) and map display software downloaded from a server on the Internet through a wireless line have been provided. According to this, the user can enhance not only the application software built in the mobile phone from the beginning but also the entertainment by operating an unspecified number of application software downloaded from a server on the Internet, for example. It is possible to improve convenience.
[0003]
By the way, in a CPU (Central Processing Unit) mounted on this type of mobile phone, for example, the output frequency of the clock is lowered, and the low power consumption operation (the power consumption is lower than the normal operation (wake-up operation)) ( By performing the sleep operation, the power consumption of the terminal itself can be reduced. However, after the application software starts operating, it is difficult for the CPU to randomly perform the low power consumption operation. This is because if the CPU randomly performs a low power consumption operation after the application software starts operating, the application software may malfunction or enter an unstable state.
[0004]
The present invention has been made in view of the above-described circumstances, and its purpose is to allow the control means to appropriately perform the low power consumption operation after the application software starts to operate, thereby enabling the terminal itself. An object of the present invention is to provide a portable terminal and a computer program that can appropriately reduce the power consumption.
[0007]
[Means for Solving the Problems]
According to the portable terminal of the first aspect , when having a telephone function for intermittently receiving the paging signal from the base station, the control means starts normal operation to start receiving the paging signal by the receiving means. After the timer value is set in the library, the timer value is set in the library when normal operation is started to start receiving the next paging signal by the receiving means before the timer value times out. Since the low power consumption operation is performed based on the timing of ending the reception of the paging signal by the receiving means immediately after being received, the low power consumption operation is performed promptly after the reception of the paging signal by the receiving means is completed. Can do.
[0008]
According to the portable terminal of the second aspect , when having a telephone function of intermittently receiving the paging signal from the base station, the control means starts normal operation to start receiving the paging signal by the receiving means. After that, the timer value is set in the library, and if the timer value times out before starting normal operation to start receiving the next paging signal by the receiving means, the timer value times out, Since the application software resumes operation and is configured to perform low power consumption operation based on the timing when the application software finishes operation, the timer value times out, the application software resumes operation, and the application software resumes operation. As soon as the operation is completed, a low power consumption operation can be performed.
[0009]
According to the portable terminal of the third aspect , when having a telephone function for intermittently receiving the paging signal from the base station, the control means starts normal operation to start receiving the paging signal by the receiving means. After that, the timer value is set in the library, and when the timer value is longer than the first predetermined time, or when the timer value times out and the normal operation starts to start receiving the next paging signal by the receiving means If the time difference from the timing to perform is shorter than the second predetermined time, the timing at which the timer value times out is ignored, and normal operation is performed based on the timing at which reception of the next paging signal by the receiving means is started. If the first predetermined time is extremely longer than the paging signal reception interval, or the second place If the time is much shorter than the paging signal reception interval, there is almost no influence from ignoring the timing when the timer value times out, so normal operation is ignored by ignoring the timing when the timer value times out. Can be performed efficiently.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment in which a mobile terminal of the present invention is applied to a mobile phone will be described with reference to the drawings.
First, FIG. 5 schematically shows a functional block and a peripheral configuration of the mobile phone. The cellular phone 1 includes a CPU (Central Processing Unit) 2 (control means in the present invention) mainly composed of a microcomputer, an RF unit 3 (reception means in the present invention) for performing RF (Radio Frequency) processing, and transmission. A key formed by arranging a number of keys such as a microphone 4 for inputting voice, a receiver 5 for outputting received voice, a “call start” key, a “call end” key, and “number” keys “0” to “9”. A pad 6, a liquid crystal display 7 that displays date / time, telephone number, and the like, and an LED (Light Emitting Diode) 8 that blinks when an incoming call is received, are connected.
[0014]
As a software configuration, the CPU 2 includes a library (platform) 2a on which an unspecified number of application software downloaded by the RF unit 3 from the server 10 on the Internet 9 through the mobile phone line 11 operates. Is started, a timer value indicating the pause time of the operation of the application software is set in the library 2a. Further, the CPU 2 can perform a low power consumption operation (sleep operation), which consumes less power than a normal operation (wakeup operation), for example, by reducing the output frequency of the clock. By doing so, it is possible to reduce the power consumption of the mobile phone 1 itself. The unspecified number of application software downloaded from the server 10 on the Internet 9 is, for example, game software or map display software.
[0015]
Next, the operation of the above-described configuration will be described with reference to FIGS. First, as shown in FIG. 1, when the application software starts to operate and receives a “timer setting” request from the application software, the library 2a sets a timer value that represents the suspension time of the operation of the application software. Then, the library 2a monitors whether or not the timer value has timed out (timer timing has ended), and when the timer value has timed out, notifies the application software of a “timeout notification” in order to notify the time-out. .
[0016]
When the other processing is completed, the other processing requests “timer value confirmation” to the library 2a to confirm the timer value set in the library 2a at that time. The other processing here is processing that is not particularly related to the operation of the application software, such as processing in which the RF unit 3 intermittently receives a paging signal from the base station.
[0017]
The library 2a receives a "timer setting" request from the application software, sets the timer value, and then receives a "timer value confirmation" request from another process before the timer value times out. Then, the minimum timer value among the timer values set at that time is extracted, and “notified minimum timer value notification” is notified to other processes in order to notify the minimum timer value.
[0018]
That is, in the library 2a, as shown in FIG. 1, only one application software has started operation, and only one timer value is set when a "timer value confirmation" request is received from another process. If so, the timer value is confirmed as the preset minimum timer value, and “notification of preset minimum timer value” is notified to other processes. On the other hand, as shown in FIG. 2, the library 2a starts when a plurality of (two in FIG. 2) application software starts operating and receives a request for “timer value confirmation” from another process. When multiple timer values are set, the multiple timer values are compared, and the minimum timer value of the multiple timer values is confirmed as the preset minimum timer value. “Timer value notification” is notified to other processes.
[0019]
In other processes, when the “notified minimum timer value notification” is notified from the library 2a in this way, the timer value is extracted from the “notified minimum timer value notification” notified from the library 2a. As will be described later, it is determined whether or not the CPU 2 may perform the low power consumption operation based on the extracted timer value. When the CPU 2 determines that the low power consumption operation may be performed, the other process notifies the CPU 2 of “sleep timer setting” to notify that the low power consumption operation may be performed. At this time, the other processing is based on the extracted timer value and the own processing, based on the extracted timer value and the time of the CPU 2 when the CPU 2 can perform the low power consumption operation, that is, the time until the CPU 2 should resume the normal operation. Determine and notify CPU2.
[0020]
When “sleep timer setting” is notified from another process, the CPU 2 sets the sleep timer value, interrupts the normal operation, and starts the low power consumption operation. The cellular phone 1 can realize a reduction in power consumption as the terminal itself by the CPU 2 performing the low power consumption operation in this manner.
[0021]
Then, the CPU 2 monitors whether or not the sleep timer value has timed out. When the sleep timer value times out, the CPU 2 notifies the other process of “time-out notification” to notify that the time-out has occurred. To resume normal operation.
[0022]
Now, some examples in the case where the CPU 2 performs the low power consumption operation in accordance with the timer value set in the library 2a will be described with reference to FIG. 3 and FIG. In the following explanation,
(1) The timer value is set after the CPU 2 starts normal operation in response to the reception of the paging signal by the RF unit 3, and the CPU 2 receives the next paging signal by the RF unit 3 before the timer value times out. (2) The timer value is set after the CPU 2 starts normal operation in response to the reception of the paging signal by the RF unit 3, and the CPU 2 receives the next paging signal by the RF unit 3. If the timer value times out before starting the normal operation accordingly (3) If multiple timer values continue (4) If the timer value is longer than the first predetermined time, or if the timer value times out The time difference between the timing at which the CPU 2 starts and the timing at which the CPU 2 starts normal operation in response to reception of the next paging signal by the RF unit 3 is the second predetermined time. Remote sequentially described each shorter.
[0023]
(1) The timer value is set after the CPU 2 starts normal operation in response to the reception of the paging signal by the RF unit 3, and the CPU 2 receives the next paging signal by the RF unit 3 before the timer value times out. In this case, as shown in FIG. 3A, after the CPU 2 starts normal operation to start receiving the paging signal by the RF unit 3 (see t1 in the figure). ) When the timer value is set in the library 2a (see t2 in the figure), the RF unit 3 starts receiving the next paging signal before the timer value times out (see t3 in the figure). Since the next normal operation is started as much as possible (see t4 in the figure), the low power consumption operation may be performed until the next normal operation is started, and reception of the paging signal by the RF unit 3 is completed. Later, it will perform low-power operation (in the figure, see t5).
[0024]
(2) The timer value is set after the CPU 2 starts the normal operation in response to the reception of the paging signal by the RF unit 3, and the CPU 2 starts the normal operation in response to the reception of the next paging signal by the RF unit 3. First, when the timer value times out In this case, as shown in FIG. 3B, the CPU 2 starts normal operation to start receiving the paging signal by the RF unit 3 (see t1 in the figure). ), When the timer value is set in the library 2a (see t2 in the figure), before starting the next normal operation to start reception of the next paging signal by the RF unit 3 (t4 in the figure). Since the timer value times out (see t6 in the figure), the low power consumption operation is not performed immediately after the reception of the paging signal by the RF unit 3 is finished (see t5 in the figure). Timer value has timed out, the application software to resume operation, immediately after the application software has terminated the operation, it will perform a low power operation (in the figure, see t7).
[0025]
(3) When a plurality of timer values are continuous In this case, as shown in FIG. 4 (a), even if the timer value A times out (see t6 in the figure), the CPU 2 Since it is set, the low power consumption operation is not performed immediately after the application software that has set the timer value A finishes the operation (see t7 in the figure). Similarly, even if the timer value B times out (see t8 in the figure), another timer value C is set, so that the application software in which the timer value B is set finishes the operation. Immediately after that, the low power consumption operation is not performed (see t9 in the figure). Then, when the timer value C times out (see t10 in the figure), the CPU 2 determines that another timer value is not set any longer. A power consumption operation is performed (see t11 in the figure).
[0026]
(4) Time difference between when the timer value is longer than the first predetermined time or when the timer value times out and when the CPU 2 starts normal operation in response to reception of the next paging signal by the RF unit 3 Is shorter than the second predetermined time, the CPU 2 originally needs to perform normal operation when the timer value times out. However, as shown in FIG. When it is longer than the first predetermined time that is extremely longer than the paging signal reception interval, or when the timer value times out (see t12 in the figure) and normal operation to start reception of the next paging signal by the RF unit 3 When the time difference from the timing (see t13 in the figure) is shorter than the second predetermined time that is extremely shorter than the paging signal reception interval , Since it is hardly affected by ignoring the timing of the timer value to time out, the timer value is even times out, it will be continued the low power operation.
[0027]
As described above, according to the present embodiment, when the application software starts operating in the mobile phone 1, the CPU 2 reduces the value based on the timer value indicating the suspension time of the operation of the application software set in the library 2a. Since the power consumption operation is performed, the low power consumption operation is performed only while the application software is suspended. Therefore, the operation of the application software is not adversely affected, and the low power consumption operation can be appropriately performed. As a result, the power consumption of the mobile phone 1 itself can be appropriately reduced.
[0028]
In this case, as an example of the operation, the CPU 2 sets the timer value in the library 2a after starting the normal operation to start receiving the paging signal by the RF unit 3, and before the timer value times out, When normal operation is started to start reception of the next paging signal by the RF unit 3, based on the timing at which reception of the paging signal by the RF unit 3 immediately after the timer value is set in the library 2a is finished. Since the low power consumption operation is performed, the low power consumption operation can be performed promptly after the reception of the paging signal.
[0029]
The CPU 2 starts normal operation to start receiving the paging signal by the RF unit 3, and then the timer value is set in the library 2 a and starts normal operation to start receiving the next paging signal by the RF unit 3. If the timer value times out before the timer value, the timer value times out , the application software resumes operation, and the low-power consumption operation is performed based on the timing when the application software terminates the operation. Since it is configured, the timer value times out , the application software resumes its operation, and the low-power consumption operation can be performed promptly when the application software finishes the operation.
[0030]
Further, the CPU 2 sets the timer value in the library 2a after starting the normal operation to start receiving the paging signal by the RF unit 3, and if the timer value is longer than the first predetermined time, the timer value When the time difference between the timing at which the timer expires and the timing at which the normal operation is started to start reception of the next paging signal by the RF unit 3 is shorter than the second predetermined time, the timing at which the timer value times out And the normal operation is performed based on the timing at which reception of the next paging signal by the RF unit 3 is started, so that the first predetermined time is much longer than the paging signal reception interval. If the second predetermined time is extremely shorter than the paging signal reception interval, the timer value times out. Since there is almost no effect of ignoring the timing, by ignoring the timing of the timer value to time out, it is possible to perform the normal operation efficiently.
