It is about a control method.

The mobile communication terminal, which is a necessity for modern people, is not only compact and lightweight due to steady development, but also is emerging as a complex communication terminal having various functions such as mp3, camera and navigation. In addition to the above functions, such a mobile terminal has a voice mail service (called a voice mail service) that allows a sender to leave a message in a recipient's voice mailbox or a fax mailbox when the receiver cannot answer a call. Voice Activated Dialing Service, a mobile communication terminal screen that allows you to make a voice call without having to dial a phone number. You can receive numbers and text messages (about 40 ~ 50 letters in English, about 80 letters in English) or various life information as texts. If you use the voice mail service, you will be notified by mobile phone when a message arrives at the voice mail. Various features and services, including support for Short Message Service (SMS) It provides.                         

On the other hand, when using a mobile terminal, a telephone call occurs in an area where radio wave reception is weak. At this time, the user extends the antenna of the mobile terminal to increase radio wave reception sensitivity. However, this method was inconvenient for the user to directly extend the antenna every time a call was made in a low reception area.

Therefore, in order to improve this, a method of automatically drawing an antenna by the power of a motor in case of poor reception sensitivity has been proposed.

3 is a flowchart of a method for automatically adjusting a call quality of a mobile communication terminal according to the present invention, unless otherwise described, the controller is performed as a subject.                     

As shown in FIG. 3, in step S11, it is determined whether there is a key input from the user through the key input unit 230. As a result of the determination in step S11, if there is no key input, step S11 is repeated until there is a key input, and if there is a key input, the flow advances to step S13 to determine whether or not it is a call command. As a result of the determination in step S13, if it is not a call command, the flow advances to step S27 to execute a command corresponding to a key input, and in the case of a call command, the flow proceeds to step S15 to measure reception sensitivity.

Next, in step S17, it is determined whether the sensitivity measurement value in step S15 is lower than a predefined reference value. As a result of the determination in step S17, if it is higher than the predefined reference value, the process proceeds to step S23. If it is lower than the predefined reference value, the process proceeds to step S19 to determine whether the speaker volume and the microphone sensitivity are amplified.

As a result of the determination in step S19, if the speaker volume and the microphone sensitivity are in the amplified state, it is already amplified, and therefore, proceeds directly to step S23. After amplifying the microphone sensitivity, the process proceeds to step S23.

In step S23, it is determined whether the call has ended. If the call is not ended, the process proceeds to step S15 again to measure reception sensitivity. If the call is terminated, the process proceeds to step S25 to restore the speaker volume and the microphone sensitivity to the default values. The process then returns to step S11 again.

On the other hand, the degree of amplification may be made in several stages according to the measured reception sensitivity, and it may be possible to amplify only the speaker volume without amplifying the speaker volume and the microphone sensitivity together. It will also be able to provide sound to indicate areas of poor reception before amplifying speaker volume and microphone sensitivity.

The method for automatically adjusting the call quality of the mobile communication terminal of the present invention is not limited to the above-described embodiment, and can be modified in various ways within the scope of the technical idea of the present invention.

According to the method for automatically adjusting the call quality of the mobile communication terminal of the present invention as described above, the step motor is not necessary because the lack of reception propagation sensitivity is amplified to improve the call quality by amplifying the speaker volume and the microphone armor. There is an effect that can reduce the volume, weight, and price increase of the terminal.
