Flowchart.

1, an antenna 20 for transmitting and receiving a signal and an RF unit 21 separate a transmission / reception frequency and transmit and receive a duplexer and a transmission signal of a mobile communication terminal. And LNA (Low Noise Amp) to amplify the received signal of the mobile communication terminal and baseband analog (BBA) part to reduce the frequency of 1.7 ~ 1.8GHz band transmitted and received from the above amplifiers by two levels to make a bit string. An IF (Intermediate Frequency) for processing data can be transmitted and received.

The MSM 22 handles modulation and demodulation for transmitting and receiving signals, and controls the operation of mobile communication terminals such as analog-to-digital converters, digital-to-analog converters, voltage control distribution, protocol processing, and the like. Built-in, the MSM 22 inputs a character input and a number, etc. of the mobile communication terminal, the keypad 24 which is an input means for using other services, the screen unit 25, the microphone, the speaker 26, The memory 23 is connected and configured. The memory 23 includes a flash memory in which a main program is stored, an SRAM (Static RAM) for receiving and storing call processing data and timer data of a mobile communication terminal from a base station, mail, telephone number, and user terminal information. It consists of EEPROM, etc. to provide storage.

The present invention grasps the field strength information when the RF unit 21 is connected to the base station and acquires a channel. When the mobile communication terminal fails to acquire more than 10 channels within a set time of about 10 minutes, only the RF power is turned off. By reducing the amount of battery consumed in the mobile communication terminal. The present invention is provided in software to control the on / off of the RF power supply.

2 is a flowchart of a battery saving method of the mobile communication terminal. When the power of the mobile communication terminal is turned on, the mobile communication terminal connects to the base station having the strongest electric field to synchronize and acquire a channel (S30 to S32). ).

On the other hand, if the mobile communication terminal is located in the weak area and the electric field strength with the base station is weak and difficult to obtain a channel, it is checked that the RF unit 21 of the mobile communication terminal is connected to the base station (S34).

The RF unit 21 checks the channel acquisition operation with the base station and checks whether the mobile communication terminal has failed to acquire more than 10 channels in 10 minutes.

When the mobile communication terminal is normally connected to the base station, the mobile communication terminal normally uses (S36 to S38).

The RF unit 21 checks the channel acquisition operation with the base station, and if the mobile communication terminal fails to acquire the channel 10 times or more in 10 minutes, the MSM controls the MSM to terminate the connection with the base station. RF off allows the user to select and set the set button (S36. S40).

When the wireless connection with the base station is cut off, the user cannot make a call to the mobile communication terminal, but other additional services such as alarm, clock, schedule management, and phone book can be used as they are, and the call information received when the RF is off is received. It can be checked and used in the call list (S42).

On the other hand, when the user moves or turns on the RF power of the mobile communication terminal (on) again to connect to the base station, as shown in step 36 to prevent the unnecessary battery consumption by counting the number of channel acquisition failures within the set time. (S44-S46).

If the connection with the base station is smooth after the RF power is turned on again, the mobile communication terminal should be used normally.

The automatic setting is selected in the RF related menu of the mobile communication terminal (S50).

The mobile communication terminal accesses a base station and acquires a channel such as obtaining synchronization to use a service such as a call (S52).

If the RF is automatically set, the RF unit 21 checks the channel acquisition process with the base station and checks whether the channel acquisition fails more than 10 times in 10 minutes (S54).

If the channel acquisition failure occurs more than 10 times in 10 minutes, such as frequent handoff due to the weak electric field received from the base station, the mobile terminal terminates the connection with the base station by turning off the RF power of the mobile terminal ( S58).

On the other hand, when normally connected to the base station to maintain a constant channel to maintain the constant power without using the power of the mobile communication terminal (S56).

Turning off the RF power does not turn off the power of the mobile communication terminal but terminates the connection with the base station. Even after the RF power off, the mobile communication terminal uses general services such as an alarm, a clock, and schedule management as it is (S60).

When the RF power is turned off, battery consumption of the mobile communication terminal is drastically reduced, and when a user needs to make a call, the user can select the RF on to immediately make a call.

In addition, after the RF power off, the mobile communication terminal checks the electric field strength information with the base station at a set time interval after a predetermined time passes and, if appropriate, can be controlled to turn on the RF power to operate normally. In this case, the RF power is kept off (S62 to S64).

As mentioned above. The present invention checks the connection status with the base station in the RF unit of the mobile communication terminal when the mobile communication terminal can not maintain the channel more than 10 times in the set time to cut off the RF power to save unnecessary battery consumption Significantly increase the use time of the mobile communication terminal.

In addition, the present invention can check the call or message received when the RF power of the mobile terminal is turned off, so if it is difficult to obtain a channel in the weak area, only the RF power off and the addition of clock, wake-up call, alarm, schedule management, etc. Since the service can be used as it is, the usage time of the mobile communication terminal is greatly increased.

According to the present invention, when the mobile communication terminal is located in the weak area, RF is automatically set or when the user cuts off the RF power, battery consumption can be significantly reduced, thereby increasing the use time.

The present invention reduces the battery consumption by detecting a weak current region with a large current consumption through an algorithm, and in particular, even when a call is difficult due to high battery consumption, a user can use the necessary functions such as a wake-up call and an alarm service without interruption. .
