The present invention relates to a wireless communication terminal and a method for limiting output data during a call, and more particularly, to improve wireless sensitivity by reducing digital noise by blocking data output to a display device during a call. The present invention relates to a wireless communication terminal having a function of limiting output data during a call so that a user can easily recognize a talk time by displaying a talk time through a separate display device.

In the present invention, a wireless communication terminal is a mobile communication terminal, a personal digital communication terminal (PCS), a personal digital terminal (PDA), a smart phone, a next generation mobile communication terminal (IMT-2000), wireless communication while being carried by an individual such as a wireless LAN terminal. Say this is possible terminal.

In general, the most significant influence on the wireless sensitivity of the wireless communication terminal when the antenna gain and the wireless transmission / reception system are normal is digital noise generated inside the wireless communication terminal. This occurs mostly in display devices (LCD modules), where a large amount of data is transmitted, and worsens wireless sensitivity by about 5 dB or more.

Therefore, the standby mode (e.g., the backlight is turned off while the folder is closed, but data is periodically transmitted to the display device once every few milliseconds), or the activation mode (e.g. menu setting via the display with the folder open, etc.) In this case, all wireless communication terminals are designed with more margin than the specification considering the effects of digital noise.

However, even in the current call mode (in a call), data is transmitted to the display device as in the active mode, which causes digital noise. Therefore, the wireless sensitivity may decrease and the reception level may suddenly drop or the call may be dropped in the weak field. The problem arises.

On the other hand, if the data is not transmitted to the display device in the call mode, digital noise does not occur, and thus the wireless sensitivity may be reduced. However, if the data is not transmitted to the display device (LCD), the display information cannot be displayed, so there is a disadvantage in that the talk time cannot be confirmed.

SUMMARY OF THE INVENTION The present invention has been proposed to solve the above problems, and a wireless communication terminal and method for limiting output data during a call for improving wireless sensitivity by cutting off data output to a display device during a call to reduce digital noise. The purpose is to provide.

In addition, the present invention, the output during the call to block the data output to the display during the call and to display the call time through a separate display device to improve the wireless sensitivity and the user can easily recognize the call time, Another object is to provide a wireless communication terminal having a data limiting function and a method thereof.

Other objects and advantages of the present invention can be understood by the following description, and will be more clearly understood by the embodiments of the present invention. In addition, it will be readily appreciated that the objects and advantages of the present invention may be realized by the means and combinations thereof indicated in the claims.

According to an aspect of the present invention, there is provided a wireless communication terminal having an output data limit function during a call, comprising: storage means for storing a program for limiting output data and a call time; First display means for displaying various screens according to the control of the control means; And stopping transmission of data to the first display means as a call starts and storing a talk time in the storage means as the call ends, thereby limiting wireless sensitivity through output data limitation to the first display means during a call. Said control means for controlling said respective components to improve.

In addition, the apparatus of the present invention to achieve the other object, the second display means for displaying the talk time under the control of the control means; And time control means for updating time information of the second display means according to the control of the control means.

On the other hand, the method of the present invention for achieving the above object, the wireless sensitivity improvement method by limiting the output data during the call in the wireless communication terminal, the control means for detecting whether the call is connected; And stopping the data transfer to the first display means by the control means as the call is connected.

In addition, the method of the present invention to achieve the other object, the method comprising the steps of the control means for transmitting the operation start signal to the second display means as the call is connected; A time control means updating the time information of the second display means so that the call time is displayed under the control of the control means while the call continues; And as the control means transmits an operation end signal to the second display means to stop the operation and store the talk time as the call ends.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, whereby those skilled in the art may easily implement the technical idea of the present invention. There will be. In addition, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating an embodiment of a wireless communication terminal having an output data limit function during a call according to the present invention.

As shown in Fig. 1, a wireless communication terminal having a function of limiting output data during a call according to the present invention includes a display device (LCD) 11 for displaying general display information. However, in the present invention, the display device 11 does not output any display information because the operation is turned off during a call. That is, the present invention stops data transmission to the display device 11 during a call.

Instead, the present invention further includes a time display device 12 for displaying only talk time separately.

The time display device 12 does not operate in the standby mode or the activation mode, and operates according to a control signal from the operation / control device 203 during a call. In addition, the operation / control device 203 updates the time information of the time display device 12 using an internal timer or a separate timer. When the call ends, the operation / control device 203 stores the call time and the call record calculated using the internal timer or a separate timer in the storage device 204.

In general, a wireless communication terminal first searches for a pilot channel and then a sync channel when the power is turned on. At this time, the time information used by the wireless communication terminal is included in the sync channel. The wireless terminal operates a timer through an internal clock with time information received from the sink channel while the pilot channel is maintained.

On the other hand, when the wireless communication terminal receives the time information from the base station can be divided into two categories. The first is when a pilot signal is missed, in which case the pilot channel is found, the sink channel is found, and the internal clock is run with new time information. The second is after the call, in which case the pilot channel is again found, the sink channel is received, and new time information is received.

Therefore, the wireless communication terminal according to the present invention receives the time information immediately after the end of the call even if the current time is not displayed during the call, so that no problem occurs in displaying the current time through the display device after the call ends.
