Separating Type Mobile Communication Terminal

The present invention relates to a detachable mobile communication terminal. More specifically, when a user uses a mobile communication terminal to use multimedia functions other than a voice call (wireless internet, camera, music play, video play, game, text message, DMB watch, memo, etc.) When the incoming call, and separates the handset fastened in the terminal body to a voice call to receive a separate mobile communication terminal that can continue to use the multimedia functions at the same time.

Recently, as computers, electronics, and communication technologies have advanced dramatically, various wireless communication services using wireless networks have been provided. Accordingly, a service provided by a mobile communication system using a wireless communication network is developing into a multimedia communication service for transmitting data such as circuit data, packet data, and the like, as well as a voice service.

In other words, with the development of electronic and communication technologies, mobile communication technologies have been commercialized and distributed, and mobile communication terminals such as mobile phones and personal portable terminals have become a necessity of modern man.

The mobile communication terminal is a terminal capable of performing voice calls and data communication while moving, and has been further miniaturized and reduced in weight for easy portability in order to maximize mobility.

In addition, such a small sized mobile communication terminal is convenient for users to carry and use, and is basically released with multimedia functions such as wireless Internet, a camera, music playback, video playback, and games.

On the other hand, the conventional mobile communication terminal is a bar (bar), slide type and most of the terminal is manufactured in the form of a folder. Such conventional terminals support multitasking functions. However, when a voice call is received while performing a multimedia function such as wireless internet, camera, music playback, video playback, or game, the terminal stops the multimedia function before making a voice call. After the voice call is terminated, the multimedia function is provided again.

However, the user has a disadvantage in that the display unit of the terminal cannot be viewed in order to use a multimedia function while performing a voice call. When using earphones provided by the terminal manufacturer, the terminal display unit can be viewed while performing a voice call, but the user has to carry the earphone at all times.

In order to solve the above problems, the present invention, the user using a mobile communication terminal multimedia functions other than voice calls (wireless Internet, camera, music playback, video playback, games, text message creation, DMB watching and notes, etc. In the case where the voice call is received when the call is received, the main purpose is to provide a separate mobile communication terminal capable of continuously using multimedia functions while receiving a voice call by separating the handsets which are fastened in the terminal body.

In order to achieve the above object, the present invention is a wireless communication function including a voice call or data communication, the terminal body having a handset fastener; A handset separated from the terminal body and fastened and fixed within the handset fastening portion; And an extension line for connecting the terminal body and the handset.

As described above, according to the present invention, a user can use a mobile communication terminal to perform multimedia functions other than voice calls (wireless internet, camera, music playback, video playback, game, text message creation, DMB viewing, memo, etc.) When the voice call is received when the call is received, the handset which is fastened in the body of the terminal is separated into stars and the voice call is received, and at the same time, the multimedia function can be continuously used.

In addition, according to the present invention, it is possible to simultaneously use the multimedia function by separating only the transmission in the voice call, there is an effect that the user's convenience and freedom is increased.

Hereinafter, some embodiments of the present invention will be described in detail through exemplary drawings. In adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are assigned to the same components as much as possible even though they are shown in different drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.
