BACKGROUND OF THE INVENTION
The present invention relates to a communication terminal apparatus and a communication control processing program thereof, and more particularly to a communication terminal apparatus having a power saving function for saving power consumption and a communication control processing program thereof.
[0002]
[Prior art]
In a mobile communication terminal device such as a mobile phone, power is usually supplied by a rechargeable battery. On the other hand, the mobile phone needs to be registered in order for the base station to recognize the current position. However, since the power consumption when transmitting to the base station for location registration is large, when location registration is frequently performed, the power reduction of the battery becomes significant even though there is no call. For this reason, proposals have been made to reduce power consumption in mobile communication terminal devices such as mobile phones.
[0003]
For example, there is a proposal of a mobile radio apparatus that reduces power consumption by reducing the frequency of location registration by normally turning off the power of a mobile phone during standby and turning it on only when necessary. According to this proposal, a mobile radio apparatus is composed of a radio telephone line terminal unit, a pager unit (a terminal unit of a mobile communication system that notifies that a message has entered from the other party using radio), and a power control unit. When waiting for a wireless phone, the power of the wireless telephone line terminal unit is turned off, and only the power of the pager unit that does not require location registration is turned on. Turn on the power of the line terminal unit, turn off the pager unit, register the location for the first time, switch to the call mode, make a call, and when the call is finished, again by the control of the power control unit, The line terminal unit is turned off and the pager unit is turned on to enter the standby state again (see Patent Document 1).
[0004]
[Patent Document 1]
JP-A-6-177824 (paragraph numbers “0005”, “0006”, FIG. 1)
[0005]
[Problems to be solved by the invention]
However, according to the configuration of Patent Document 1, since the power supply of the wireless telephone line terminal unit is turned on every time the pager receives an incoming call, the power consumption increases rather when the incoming frequency to the pager is high. End up. In addition, since control for reducing power consumption is left to the outside, independent control design cannot be performed. In particular, in recent years, there is a flood of malicious commercial law and mischievous calls using incoming calls called “Wangiri”, so when receiving frequent incoming calls, the power consumption instead of the configuration of Patent Document 1 above. The problem of inviting an increase occurs. In addition, the addition of a pager unit as an incoming sensor for control by the power supply control unit causes a new problem that it causes an increase in cost and becomes an obstacle to reducing the size and weight of the apparatus.
[0006]
The present invention solves such a conventional problem, and can reduce power consumption reasonably without adding new parts that cause an increase in cost and obstruct the reduction in size and weight of the apparatus. It is an object of the present invention to provide a communication terminal device that can be achieved and a program for its communication control processing.

Further, the key input unit 5 is provided with an off-hook switch 51 and an on-hook switch 52 in addition to a power switch, a numeric key switch, a clear switch, a transmission switch, a mail switch, and the like (not shown). The back key 8 is made of a transparent or translucent member and incorporates an LED 81 that blinks in response to an incoming call. In addition, a vibrator 10 that notifies an incoming call by vibration is built in the main body case.
[0011]
Next, an electrical configuration will be described. The wireless transmission / reception unit 11 transmits or receives modulated voice and data via the antenna 2. The wireless signal processing unit 12 demodulates the voice and data received by the wireless transmission / reception unit 11 and modulates the voice and data transmitted by the wireless transmission / reception unit 11. The control unit 13 controls the entire apparatus, and includes a timer 131 that generates a timer interrupt every predetermined time (referred to as “timer minimum unit time”).
[0012]
The subscriber information storage unit 14 includes an address book area, an area for receiving BOX for storing incoming mail, an area for transmitting BOX for storing outgoing mail, and the like. The system ROM 15 stores a communication control processing program executed by the control unit 13 and various initial data. The memory 16 is a work area that temporarily stores data to be processed by the control unit 13 such as data input from the outside, data output to the outside, and data exchanged internally.
[0013]
The voice signal processing unit 17 converts a voice signal during a call from digital to analog and gives the sound to the speaker 3, and converts the voice signal from the microphone 6 from analog to digital and inputs it to the control unit 13. The driver 18 drives the LED 81 of the back key 8, the speaker 9, and the vibrator 10. The driver 19 drives the display unit 4. The driver 20 drives the sub display unit 7.
[0014]
Next, the operation of the first embodiment configured as shown in FIG. 1 will be described based on the operation flowchart of the control unit 13 shown in FIGS. Note that the control unit 13 does not completely stop operating even when the power switch is off. For example, a process for detecting the on / off state of the power switch or a specific process as described later is performed.
FIG. 2 is a main flowchart of communication control processing by the control unit 13. First, it is determined whether or not the power switch is turned on (step SA1). When the power switch is turned on, the flag ONF is set to “1 (normal operation mode)” (step SA2). Then, the timer interrupt is prohibited (step SA3) and supplied to the communication unit such as the wireless transmission / reception unit 11 and the wireless signal processing unit 12, and the display unit including the drivers 19, 20, the display unit 4, the sub display unit 7, and the like. The power to be turned on is turned on (step SA4).
[0015]
If the power switch is not turned on in step SA1, it is determined whether or not the power switch is turned off (step SA5). If it is turned off, ONF is set to “0 (power saving operation mode)” and the timer register T “0” is stored in (step SA6). Then, the power supplied to the communication unit and the display unit is turned off (step SA7), and the timer interrupt prohibition is canceled (step SA8).
[0016]
After turning on the power to the communication unit and the display unit in step SA4, or after canceling the timer interrupt prohibition in step SA8, or when the power switch is not operated, the ONF value is “1”. Or “0” (step SA9). When the ONF is “1”, the normal operation mode is set and the on process is executed (step SA10). When the ONF is “0”, the power saving operation mode is set and the off process is executed. (Step SA11).
[0017]
3 and 4 are flowcharts of the ON process in step SA10 in the main flowchart. First, a standby screen is displayed on the display unit 4 (step SB1). Next, it is determined whether or not it is off-hooked by operating the off-hook switch 51 of the key input unit 5 (step SB2). When it is off-hook, a number input screen is displayed (step SB3). And it is discriminate | determined whether the number was input with the ten key switch (step SB4). When a number is input, the number is displayed (step SB5). Next, it is determined whether or not the transmission switch is turned on (step SB6). If this switch is not on, it is determined whether or not the clear switch is on (step SB7). When the clear switch is turned on, the input data is erased (step SB8). And it transfers to step SB1 and a standby screen is displayed. If the clear switch is not on, the process proceeds to step SB4 and waits for a number input.
[0018]
When the transmission switch is turned on in step SB6, a transmission process for transmitting to the destination of the input number is performed (step SB9), and a ringing tone is notified from the speaker 3 (step SB10). Then, it is determined whether or not a line connection has been established (step SB11). When the connection is established, the notification of the ringing tone is stopped, the call mode is changed to the call mode (step SB12). In the call mode, it is determined whether or not the on-hook switch 52 has been turned on (step SB13). When the on-hook switch is set, the call mode is changed to the standby mode, and the standby screen is displayed by moving to step SB1. indicate.
[0019]
If it is not off-hook in step SB2, it is determined whether or not an incoming call is detected in the flowchart of FIG. 4 (step SB14). When an incoming call is detected, the incoming call is notified by the speaker 9 and the LED 81 of the rear key 8 (step SB15). Then, it is determined whether or not it is off-hooked by the operation of the off-hook switch 51 or the operation of the back key 8 (step SB16). When it is off-hook, the incoming call notification is stopped, the mode is changed to the call mode, and the call process is performed (step SB17). In this call mode, it is determined whether or not the mobile phone is on-hooked (step SB18). When the mobile phone is on-hooked, the standby mode is entered, and the standby screen is displayed in step SB1 of FIG.
[0020]
If no incoming call is detected in step SB14, it is determined whether an incoming mail has been detected (step SB19). When an incoming mail is detected, the incoming mail is notified by the speaker 9 and the LED 81 of the back key 8 (step SB20). Thereafter, the process proceeds to step SB1 in FIG. 3 to display a standby screen.
If no incoming mail is detected, it is determined whether or not the mail switch is turned on (step SB21). When this switch is turned on, mail processing is executed (step SB22), and the process proceeds to step SB1 in FIG. 3 to display a standby screen. If this switch is not on, the reception level is detected (step B23), and it is determined whether or not the reception level is lowered (step SB24). If the reception level is lowered, a location registration process is performed on the base station (step SB25). After the position registration process or when the reception level has not decreased, the process proceeds to step SB1 in FIG. 3 to display a standby screen.
[0021]
FIG. 5 is a flowchart of the off process in step SA11 in the main flowchart of FIG. First, it is determined whether or not the minimum timer unit time has elapsed (step SC1), and when it has elapsed, the value of the timer register T is incremented by "1" (step SC2). Then, it is determined whether or not the value of T has reached a predetermined value (step SC3). When the value of T has not reached the predetermined value, this flow is terminated, but when it has reached the predetermined value, the power supplied to the communication unit is turned on (step SC4).
[0022]
Next, a location registration process is performed by transmitting to the base station (step SC5). Further, new mail inquiry processing is performed (step SC6), and it is determined whether there is a new mail (step SC7). If there is a new mail, the mail is received and stored in the reception BOX (step SC8). After storing the new mail, or when there is no new mail in step SC7, the value of T is returned to the initial value “0”, and this flowchart is terminated to return to the main flowchart of FIG.
[0023]
FIG. 6 is a flowchart of the mail process in step SB22 in the ON process of FIG. First, a mail menu is displayed (step SD1), and it is determined whether or not a menu is selected by operating the key input unit 5 (step SD2). If the menu is not selected, it is determined whether or not the clear switch is turned on (step SD3). When this switch is turned on, this flowchart is ended, and the process returns to the ON process flowchart of FIG. If this switch is not turned on, it waits for menu selection on the mail menu screen.
[0024]
When a menu is selected, it is determined whether or not the selected menu is newly created (step SD4). If it is newly created, a new creation screen is displayed (step SD5). Then, data input is performed according to an operation from the key input unit 5 (step SD6). Thereafter, the mail created according to the operation of the transmission switch is transmitted (step SD7) and stored in the transmission BOX (step SD8).
[0025]
If the selected menu is not newly created, it is determined whether or not a new mail inquiry menu has been selected (step SD9). When this menu is selected, a new mail inquiry process is performed (step SD10). Then, it is determined whether there is a new mail (step SD11), and if there is a new mail, it is stored in the reception BOX (step SD12).
[0026]
If the selected menu is not a new creation or new mail inquiry, it is determined whether or not a menu for the reception BOX has been selected (step SD13). When this menu is selected, reception BOX processing is performed (step SD14). For example, processing such as browsing, replying, registering, and deleting the received BOX is performed according to the operation. If the selected menu is not the reception BOX, it is determined whether or not the transmission BOX menu is selected (step SD15). When this menu is selected, transmission BOX processing is performed (step SD16). For example, processing such as browsing and deleting the transmission BOX is performed according to the operation. If the selected menu is none of the above, it is determined whether or not another menu such as mail setting has been selected (step SD17). When another menu is selected, other processing is performed (step SD18).
[0027]
As described above, according to the mobile phone 1 according to the first embodiment which is a communication terminal device of the present invention, the control unit 13 operates in the normal operation mode or the power saving operation mode according to the on state or the off state of the power switch, respectively.

Set individually based on. For example, when working from 9 am to 5 pm without moving in the office, there is no need to frequently register the location, but there is a case where it is desired to receive incoming mail frequently. In such a situation, the time from the location registration to the next location registration is set to be long, and the time from the arrival of the received mail to the next arrival is set to be short. In this case, since transmission with high power consumption is not frequently performed, it is possible to rationally reduce power consumption suitable for the actual situation.
[0030]
Next, a fourth embodiment will be described.
In the fourth embodiment, the predetermined time is set based on the day of the week or time zone input by the user's operation and a pattern corresponding to the numerical value. For example, there are many cases where the life pattern is different between the weekday and the holiday even in the same time zone. Therefore, it is possible to rationally reduce power consumption according to lifestyle patterns by inputting different patterns depending on the combination of day of the week or time zone and numerical values, and setting the time interval for incoming positions of incoming mail and incoming mail. it can.
