Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the same elements in the figures are represented by the same numerals wherever possible. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

1 is a block diagram of a portable wireless terminal according to an embodiment of the present invention. Referring to FIG. 1, the controller 20 performs an overall control operation of the mobile phone. The wireless unit 22 controls transmission and reception of voice data and control data under the control of the control unit 20, and the voice processing unit 24 controls the voice data received from the wireless unit 22 under the control of the control unit 20. (speaker) Converts to an audible sound through the SPK and outputs the voice signal received from the microphone (microphone) MIC to the wireless unit 22 to output the data. The key input unit 26 includes a plurality of numeric keys and function keys, and outputs key input data corresponding to a key pressed by the user to the controller 20. The display unit 28 displays various messages and the like under the control of the control unit 20. The memory unit 30 includes a program memory for storing program data necessary for controlling a mobile phone operation, and a data memory for storing data generated during control or during execution by a user. The buzzer BZ generates a buzzer sound such as an alarm under the control of the control unit 20.

In the embodiment of the present invention, as shown in FIG. 1, the power supply unit 36 includes a system clock providing unit including a main oscillation unit 32 and a sub oscillation unit 34. The power supply unit 36 converts the battery power of the portable wireless terminal into powers PW required for each sub-circuit, and corresponds to various circuit parts of the portable wireless terminal based on the power control PWC of the control unit 36. To supply. In an embodiment of the present invention, the control unit 20 selectively uses two clock sources for the system clock. One of the two clock sources is the main system clock M_CLK provided by the main oscillator 32 and the other is the sub system clock S_CLK provided by the sub oscillator 34. . The frequency of the main system clock M_CLK is tens of MHz and the frequency of the sub system clock S_CLK is tens of KHz. The portable wireless terminal consumes less battery power when the controller 20 uses the sub-system clock S_CLK than when the control unit 20 uses the main system clock M_CLK. For example, when the control unit 20 uses the main system clock M_CLK, the battery power consumption is about several tens of mA, and when the sub system clock S_CLK is used, the battery power consumption is about several mA.

In the embodiment of the present invention, the controller 20 selectively uses two clock sources, that is, the main system clock M_CLK and the sub system clock S_CLK, in order to maximize the battery life of the portable wireless terminal. According to an exemplary embodiment of the present invention, when the controller 20 performs a call-related operation, the main system clock M_CLK is used, and in most other standby states, the sub system clock S_CLK is used. Performing the call-related operation refers to a case in which the controller 20 has a lot of work to be done by the user attempting a call or performing other operations or signal communication with a base station. In addition, most of the other standby states mean that there is no user operation and signal communication with the base station is stable. When the standby state as described above, the control unit 20 according to an embodiment of the present invention uses the sub system clock S_CLK provided by the sub oscillation unit 34. At this time, the control unit 20 operates with the sub-system clock S_CLK and monitors the call paging timing and whether any function set by the user operates. In the case of a code division multiple access (CDMA) terminal, the control unit 20 maintains a slotted mode to save battery power in a standby state and receives a call by checking a preset slot of a paging channel. Check the timing. In the case of a GSM (Global System for Mobile telecommunications) terminal, the controller 20 checks a timing at which a call is received since its reception frame interval is determined in a standby state. Therefore, the controller 20 uses the sub-system clock S_CLK provided by the sub oscillator 34 in a period in which the timing of receiving the call does not need to be checked as described above. The controller 20 uses the main system clock M_CLK provided by the main oscillator 32 when it is close to the timing at which the call is received.

In this way, the control unit 20 can create a condition in which the control unit 20 consumes the least battery power. The controller 20 may turn off or on the power supplied to the call-related circuit block of the portable wireless terminal according to a user's request. This can reduce the battery power of the portable wireless terminal to the maximum.

According to an embodiment of the present invention, when the user of the portable wireless terminal requests an alarm only function, the control unit 20 stops supplying power to call-related circuit blocks until an alarm time set by the user. Therefore, the controller 20 does not even perform the operation of checking the timing at which the aforementioned call is received. The control unit 20 operates with the sub system clock S_CLK provided by the sub oscillator 34 and performs only an operation related to the alarm time check.

2 is a control flowchart for an alarm function according to an embodiment of the present invention.

1 and 2 will be described in detail the operation of the alarm function according to an embodiment of the present invention.

When the user requests a dedicated alarm function using the key input unit 26 of the portable wireless terminal, the control unit 20 determines this in step 100 of FIG. 2 and proceeds to step 102. The dedicated alarm function is to carry out a function of providing a user with an alarm only at a set time without performing a call related function of the portable wireless terminal. When the dedicated alarm function request is made as described above, the control unit 20 proceeds to step 102 of FIG. 2 as described above to enter the alarm time setting mode. When the alarm time setting mode is entered, the user can set a desired alarm time using the key input unit 26.

When the user completes the alarm time setting, the controller 20 determines this in step 104 of FIG. 2 and proceeds to step 106. The control unit 20 displays to the user via the display unit 28 that the portable wireless terminal is now operating the dedicated alarm function from step 106 and proceeds to step 108. In step 108, the control unit 20 controls the power supply unit 36 to cut off battery power supply to the call-related circuit parts, and to supply battery power only to the alarm function-related circuit parts. An example of the call-related circuit units may be the wireless unit 22, the voice processing unit 24, or the like of FIG. 1. An example of the circuit units related to the alarm function may include the control unit 20, the memory 30, and the key input unit of FIG. 1. And a display unit 28. The controller 20 selects and uses the sub system clock S_CLK provided by the sub oscillator 32. By using the sub-system clock S_CLK, the controller 20 forms a condition that consumes less battery power. Furthermore, since all of the call-related circuit units are powered off, the power of the battery can be reduced as much as possible. In addition, the embodiment of the present invention has the advantage that does not generate a ringing sound and a warning sound that may be unpleasant to the user taking a good night's sleep after setting the wake-up call as the call-related circuits do not operate.

The battery power is supplied only to the alarm function-related circuits in the portable wireless terminal, and the controller 20 drives the alarm timer with the sub-system clock S_CLK. Thereafter, the control unit 20 determines whether the scheduled alarm time has reached (step 110 in FIG. 2), that is, the alarm timer has expired.

If the scheduled alarm time is not reached, the controller 20 proceeds to step 112 of FIG. 2 to determine whether there is a request for canceling the dedicated alarm function from the user. The user may make a request for canceling the dedicated alarm function through the key input unit 26. If there is a request for canceling the dedicated alarm function from the user before the scheduled alarm time, the control unit 36 controls the power supply unit 36 to supply power to the call-related circuit unit where the battery power supply is cut off. Then, the main system clock M_CLK provided by the main oscillator 32 is used as the system clock.

On the other hand, in step 110, when the predetermined alarm time arrives, the controller 20 proceeds to step 116 of FIG. 2. In operation 116 of FIG. 2, the controller 20 provides an alarm sound to the user through the buzzer BZ. In more detail, the power supply unit 36 is controlled to supply power to the call-related circuit unit where the battery power supply is cut off. In addition, the main system clock M_CLK provided by the main oscillator 32 is used as the system clock. In this state, the control unit 20 provides an alarm sound to the user through the buzzer BZ. The alarm method may be provided as the alarm sound as described above, but may also be provided as a vibration using a vibration motor and may be displayed as a display window. The combination of the two can also provide an alarm to the user.

In the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be determined by the equivalent of claims and claims.

As described above, the present invention stops various operations of the portable wireless terminal during the alarm function operation, minimizes power consumption, does not generate an unpleasant ringing sound and a warning sound, and normally restores the operation of the portable wireless terminal after the alarm. There are advantages to giving.
