Device and method for automatically controlling antenna of mobile communication terminal {Method and device for auto controlling antenna in mobile station}

The present invention relates to an apparatus and method for automatically controlling an antenna of a mobile communication terminal, and more particularly, a movement capable of maintaining an optimal call quality by automatically moving an antenna up and down at an appropriate time according to a received signal of a terminal. An automatic control device for an antenna of a communication terminal.

Today, with the remarkable developments in the fields of electricity, electronics and telecommunications, there is a rapid change in the information and communication environment. Among these changes, mobile communication is being used as much as it is regarded as a necessity in modern society. With the expansion of the base of such mobile communication, various functions are added to the terminal, and development and application of information communication related technologies using mobile communication are actively progressing.

On the other hand, the mobile communication terminal has recently been able to use the Internet (internet) as well as telephone, message transmission and reception, data storage function, weather, securities such as receiving various text services (service), The usage time of mobile communication is gradually increasing.

In such mobile communication, the most important things are convenience of use, improvement of the call quality, stability of data transmission, and the like.

On the other hand, in the current mobile communication terminal, when the user with the terminal is in a position where the call quality is not good, there is no appropriate measures to improve the call quality.

However, in order to receive a radio signal, an appropriate length of an antenna is required according to each signal. Therefore, lengthening the antenna of a terminal can make the state of receiving a signal more stable.

However, in general, users tend to talk without raising the antenna, and if the call quality is poor while the user is talking, the user must stop the call and raise the antenna every time. There is also the hassle of having to lift the user directly.

In the related art, in order to reduce the inconvenience of the above, there is a function of controlling the antenna electrically using the provided button, but this also requires the user to control the antenna by operating a button on the terminal, so that the terminal of the terminal during the call The hassle of checking the terminal in order to press the button is followed.

The present invention has been made to solve the above problems, and checks the strength of the signal received from the mobile communication terminal and the error rate of the signal, and automatically moves the antenna up and down when the received signal is not stable, thereby making the best call. An object of the present invention is to provide an automatic antenna control device of a mobile communication terminal capable of maintaining a state.

In order to solve the above problems, the automatic antenna control apparatus of the mobile communication terminal according to the present invention, by checking the strength and error rate of the received signal and generating a control signal suitable for the MSM, and by the control signal of the MSM And a motor control unit for generating a motor control signal, a motor operated by the motor control signal of the motor control unit, and gear means for moving the antenna up and down by operation of the motor.

Here, the gear means is preferably composed of a pinion gear connected to the rotating shaft of the motor and a rack gear attached to the pinion gear (pinion gear) and the dental gear.

In addition, the method of automatically controlling the antenna of the mobile communication terminal according to the present invention includes determining whether the antenna is raised when a call is started, and determining whether the automatic antenna control is set when the antenna is not raised in the determination. And checking the signal strength and error rate from the received signal, if the automatic antenna control is set in the step, determining whether the checked value exceeds a preset threshold value; In the case of exceeding the threshold at, if the antenna is raised again, the step of raising the antenna only if it is not raised.

According to the present invention, the optimum reception state can be maintained by automatically moving the antenna up and down in accordance with the reception state.

In the present invention, as a factor for determining call quality in a signal received from a mobile terminal, a frame error rate (FER) indicating an error rate of a received signal strength indicator (RSSI) indicating a received signal strength and a ratio of error data to transmitted data ).

When receiving a radio signal, in order to maintain the reception state optimally, the reception state can be satisfactorily improved by raising the antenna of the terminal according to the length of the wavelength of the radio signal. Therefore, when the intensity of the received signal falls below an arbitrary setting value or the error rate rises above an arbitrary setting value, the antenna is raised to improve the reception state.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing an antenna automatic control apparatus of a mobile communication terminal according to the present invention.

Referring to FIG. 1, an apparatus for automatically controlling antennas of a mobile communication terminal according to the present invention includes an MSM 101 for checking an intensity and an error rate of a received signal and generating a control signal suitable for the MSM 101. The motor control unit 102 generating a motor control signal by a control signal, the motor 103 operating by the motor control signal of the motor control unit 102, and the antenna 104 up and down by operation of the motor. A gear means for moving.

Here, the gear means is preferably composed of a pinion gear 103a connected to the rotating shaft of the motor 103 and a rack gear 104a attached to the pinion gear 103a and pressed against the antenna 104.

Referring to the operation of the antenna automatic control device of the mobile communication terminal, when the call is started, the MSM 101 checks the strength and error rate of the signal from the signal received by the terminal during the call, and the appropriate control signal to the motor control unit Send to 102. Then, the motor control unit 102 having received the control signal generates a suitable motor control signal to drive the motor 103.

Then, the pinion gear 103a connected to the rotation shaft of the motor 103 and the rack gear 104a attached to the antenna 104 are pressed against each other, and the rack gear is rotated by the rotation of the pinion gear 103a. The antenna 104 with the 104a attached is interlocked up and down.

Here, the automatic control method of the mobile communication terminal according to the present invention will be described in detail.

First, when the call of the terminal is started (step 201), the MSM 101 first determines whether the antenna 104 is raised (step 202), and in the determination, if the antenna 104 is not raised, the antenna is automatically controlled. It is determined whether is set (step 203).

If the automatic antenna control is set in step 203, the strength and error rate of the signal are examined from the received signal (step 204) to determine whether the strength and error rate of the signal exceeds a user-set threshold value (step 204). Step 205).

When the signal strength and the error rate exceed the threshold in step 205, it is again checked whether the antenna is raised (step 206), and the antenna is raised only when it is not raised (step 207).

When the call ends (step 208), the antenna is lowered again (step 209).

On the other hand, if the antenna is raised when the call is started in step 202, or the antenna automatic control is not set in step 203, and when the antenna is again checked in step 206, the antenna is raised. If so, the automatic control operation ends.

In addition, when the user performs the operation of raising or lowering the antenna during the automatic antenna control operation, it is preferable to stop the antenna automatic control operation as described above.

As described above, the automatic antenna control device of the mobile communication terminal according to the present invention, by checking the signal received when the call is started and automatically raises the antenna when the reception state is not good, the user according to the call state each time You can maintain the optimal call state without raising the antenna.
