Abstract

PURPOSE: A method for setting a clock exclusive mode of a mobile communication terminal is provided to reduce power consumption of a battery by setting a mode totally separating a clock function and a telephone function. CONSTITUTION: A control part measures RSSI of a receiving signal and examines whether the measure RSSI is smaller than the reference value(301). If larger, the control part performs general clock function(303). If smaller, the control part operates the first count time to count time when the RSSI is received in value smaller than the reference value(305). The control part periodically compares the first time preliminarily saved, with the count time of the first count timer(307). If the count time of the first count timer is larger than the first time, the control part stops operating the first count time and operates the second count time to count receiving signal checking intervals(309). The control part provides power only to construction for operating clock function(311). It is examined whether the count time of the second count time exceeds the second time preliminarily saved(313). If exceeds, the control part opens the second timer(315).

Description

How to set dedicated watch mode for mobile communication terminal {METHOD FOR SETTING CLOCK FUNCTION EXCLUSIVE MODE IN MOBILE COMMUNICATION TERMINAL}

The present invention relates to a clock function of a mobile communication terminal, and more particularly, to a method of using a mobile communication terminal only for a clock according to a user and a channel environment.

In general, a mobile communication terminal operates using a rechargeable battery having a limited lifetime to provide mobility. Therefore, in the mobile communication terminal, methods and circuits that can prolong the life of the battery are being actively studied.

In general, a mobile communication terminal is provided with a clock function that informs the current time to provide convenience to the user with mobility. The clock of the mobile communication terminal initially receives the time data from the Global Positioning System (GPS) when the power is turned on, adjusts the initial time, and then operates by the internal power source to display the correct time. give. As described above, the clock of the mobile communication terminal operates by power input from a battery. However, since the battery life of the mobile communication terminal is limited, the clock function cannot be used when the battery power is exhausted.

As described above, it is pointed out that the mobile communication terminal performs an operation by the battery and extends the life of the battery. However, when the mobile communication terminal enters an incapable region such as a shadow area, the mobile communication terminal periodically turns on the reception to catch the synchronization signal, which consumes a lot of power. In this case, since the battery power of the mobile communication terminal provided to the user is quickly consumed, there is a problem that even a function of the mobile communication terminal such as a clock function cannot be used.

Accordingly, the present invention provides a method for turning off the original call function and turning on additional functions only when the mobile communication terminal is located in an area where communication is impossible.

In order to achieve the above object, the present invention provides a first key which is a duration of a received signal level that is weaker than a pre-stored reference value in order to switch from the normal function mode to the watch-only mode when a predetermined key is input and enters the watch setting-only automatic setting mode. A method for switching an additional function dedicated mode in a mobile communication terminal in which an additional function dedicated mode is set in which a time and a second time, which is a received electric field strength level check interval time of a received signal in the clock only mode, are measured. And when the received electric field strength is less than the reference value during the first time, switching to the clock function dedicated mode, and when the time when the switching to the clock function dedicated mode exceeds the second time, switches to the general function mode. Characterized in that the process is made.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals have the same reference numerals as much as possible even if displayed on different drawings. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a block diagram of a mobile communication terminal to which the present invention is applied. A description with reference to FIG. 1 is as follows.

The controller 101 controls the overall operation of the mobile communication terminal. The control unit 101 also has a configuration for controlling the additional function of the mobile communication terminal. In FIG. 1, only the watch function controller 105 controlling the overall operation of the watch function according to the present invention is illustrated. The memory 103 is composed of a ROM storing an operating program, a RAM temporarily storing data generated during an operation program operation, an electrically programmable EEPROM, and the like. The radio unit 109 processes a signal transmitted and received through a radio link under the control of the controller 101. The reference frequency generator 111 is controlled by the controller 101 and generates a reference frequency required by the mobile communication terminal. The controller 101 receives the reference frequency, generates a clock for a clock function, and provides the clock to the clock function controller 105. The key input unit 115 includes a plurality of numeric keys and function keys, and generates key data for the keys and outputs the key data to the controller 101. The display unit 113 receives and displays the display data of the key data generated at the singer key input unit 115 from the controller 101, and displays the operation state of the mobile communication terminal as text and an icon. The power supply unit 117 includes a battery, and converts the power provided from the battery into operating power of each of the components and supplies them to the corresponding components.

2 is a flowchart illustrating a method of setting a watch-only mode of a mobile communication terminal according to an exemplary embodiment of the present invention. Referring to FIG. 2, when the watch-only mode setting method is described, when the key for menu setting is input from the key input unit 115, the controller 101 enters the menu setting mode in step 201 and displays menus on the display unit 113. Display. In the menu setting mode, the controller 101 proceeds to step 203 and checks whether a clock setting mode key for entering the clock setting mode among the displayed menus is input from the key input unit 115. When a key for clock setting is input in step 203, the controller 101 displays a sub-menu for the clock setting mode on the display unit 113. At this time, the menu displayed on the display unit 113 according to the present invention displays three menus, a general watch mode, a watch only mode, and an auto watch mode. After the step 203, the control unit 101 at step 205, step 209, step 213, the normal clock mode performing both the telephone function and the clock function, the clock-only mode performing only the clock function, the clock according to the state of the received signal Determines whether the dedicated mode or the automatic clock-only mode that automatically switches the normal mode is selected. If the general clock mode is selected in step 205, the control unit 101 proceeds to step 207 performs a general operation of performing both the phone function and the clock function to display the time. If the clock-only mode is selected in step 209, the controller 101 proceeds to step 211 to operate only a clock function. That is, power is supplied only to the clock function controller 105, the display unit 113, and the reference frequency generator 111 for clock operation, and does not supply power to the components for the call. If the automatic clock only mode is selected in step 213 of the sub menus of the clock setting mode, the controller 101 proceeds to step 215 and displays a message requesting to set the level duration of the weak reception signal on the display unit. If the duration of the weak received signal level input through the key input unit 115 is input, the input information is stored and the process proceeds to step 219. In step 219, the controller 101 displays a message for setting the received signal level check interval time on the display unit to check whether the received signal level check interval time is set. If the received signal level check interval time is input in step 219, the information is stored and terminated in step 221. However, if the reception signal level check interval time is not set in step 219, the controller 101 proceeds to step 223 and checks whether the setting is completed. If the reception signal level check interval time is not set and setting of a machine function is completed, the controller 101 may set the reception signal level check interval time as a default value. The default value is generally set longer than the receiver turn-on cycle time in the standby state of the terminal.

3 is a flowchart illustrating a method for switching an automatic watch dedicated mode according to a received electric field strength when an automatic watch dedicated mode is set in a mobile communication terminal according to an exemplary embodiment of the present invention.

Hereinafter, referring to FIG. 3, an operation when the automatic watch dedicated mode is set in FIG. 2 will be described.

The controller 101 measures the received electric field strength (RSSI) of the signal received in step 301 and checks whether the measured received electric field strength is smaller than a preset reference value. If the received field strength is smaller than the reference value, the controller 101 proceeds to step 305. If the received field strength is greater than the reference value, the controller 101 proceeds to step 303. In step 303, a general clock function is performed. The control unit 101 proceeds to step 305 to drive a first count timer (not shown) to count the time the RSSI is received with a value less than the reference value. After driving the first count timer, the controller 101 periodically compares the first time set in step 215 of FIG. 2 with a pre-stored count time of the first count timer in step 307. If the time is greater than the count time of the first count timer, the process after step 301 is repeated, and if the count time of the first count timer is greater, the process proceeds to step 309 to stop the operation of the first count timer and receive the count. A second count timer (not shown) for counting the signal check interval time is driven. When the second count timer is driven, the controller 101 proceeds to step 311 to supply power only to the configuration for the clock function operation and not to supply the remaining components, that is, the components for the call. After step 311, the controller 101 proceeds to step 313 to check whether the time counted by the second count timer exceeds the second time set in step 221 of FIG. If the time counted by the second count timer exceeds the second time, the controller 101 proceeds to step 315 to turn off the second count timer and returns to step 301 to repeat the subsequent process.

In the present invention, only the watch function is described. However, the present invention may be applied to other functions of the mobile communication terminal as well as the watch function.

Therefore, the present invention reduces the power consumption of the battery while using the clock function that the user wants to use in a state where the user does not want to call or poor reception state by setting a mode that can completely separate the clock function and the telephone function in the mobile communication terminal. There is an advantage to this.
