In particular, the present invention relates to a m- A multimedia terminal having a VoIP communication function is detachable from a terminal detachable unit, a package body having a display unit having a size larger than a screen unit of the multimedia terminal, or a first processing unit provided inside the multimedia terminal, And a web surfing function. The package body and the terminal detachable unit are connected to each other And a first folding portion for foldably connecting one side of the package main body and one side of the terminal detachment portion so as to be folded and folded as shown in FIG. 1B. The two pairs of toothed wheels are engaged with each other around the four ends of the upper and lower sides of the H- And a second folding part formed to be folded or unfolded in any direction in the reverse direction and connected to one side of the expansion unit for expanding the function of the multimedia terminal and one side of the package body, M-VoIP communication method using serial bus wire communication in which the front surface of the display unit is folded so as to cover the display unit so that the display unit can be portable without using or using suspenders in the size of the display unit, The handler for portable package Will.

As is well known, the development of technology is the biggest characteristic that distinguishes it from general phone (feature phone). Openness that enables sharing of various applications (application programs) among general users based on universal operating system and open operating system, And tablet PCs, application developers are also provided with a standardized development environment, allowing them to freely develop mobile applications through an open operating system. As the performance of portable and smart devices including notebook PCs increases, and the spread of wireless Internet by the interlocking of mobile-IP network and wired IP network spreads, a larger display (display screen) and a keyboard (QWERTY keyboard) , The use of larger capacity batteries that can be used longer is increasing. In addition, a wireless Internet access device in the form of a dongle (a device connected to an input / output port of a computer / a port connected to a port) that enables a wireless Internet service supporting mobility to portable and smart devices is also introduced.

In accordance with the necessity, the conventional portable terminals having a display of about 2 to 3 inches are inclined to have a display of 5 inches or more, which is not enough to be used in portable and smart devices equipped with a display having a size of 6 inches and 9 inches Terminals are manufactured, and terminals equipped with a QWERTY keyboard are also introduced.

However, as the size of the display increases, the battery consumption increases. In order to provide a separate QWERTY keyboard or the like, the thickness of the multimedia terminal may be increased or the size of the display may be reduced. In addition, although the mobility is provided by a dongle-type wireless Internet access device, it is used in a notebook PC or a tablet-sized portable device. Therefore, a mobile VoIP call (here, a call includes not only a simple voice call but also a streaming of multimedia data ) Is inconvenient, the battery is exhausted quickly, and there is a difficulty in disconnection of a call such as a disconnection during a call. Here, mobile VoIP (m-VoIP) refers to a mobile voice over Internet Protocol (VoIP) using a mobile communication network supporting a Wi-Fi (Wi-Fi, wireless LAN) or a third generation (3G) Skype, viber, fring, tango, nimbuzz, and line are being downloaded to the handset.

In order to solve such a problem, a technique has been proposed in which a separate display can be extended and added. As a representative example thereof, Korean Patent Publication No. 10-2004-0107863 (entitled: Hereinafter referred to as "cited invention").

1 and 2, a main LCD panel 1 is coupled to a main body of a mobile communication terminal and includes a port 1a through which data can be transmitted to both sides of the main LCD panel 1; A first LCD panel (2) having a connector on one side to be fitted into one port (1a) of the main LCD panel (1); A second LCD panel (3) having a connector on one side to be fitted to the other port (1a) of the main LCD panel (1); And a port protection plate (1) sandwiched between both sides of the main LCD panel (1) in order to protect both side ports (1a) of the main LCD panel (1) while the first and second LCD panels The first and second LCD panels 2 and 3 are connected to both sides of the main LCD panel 1 according to need, and the display unit is extended to the side of the main LCD panel 1 It is possible to use a wider display unit as needed. However, since the LCD panel is divided into three LCD panels, complicated processing is needed to display the same as one LCD panel, and the first and second Not only the LCD panels 2 and 3 need to be separately provided but also the LCD panel and the panel connecting part are exposed with lines, which hinders the display of the display part.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a mobile communication system, a mobile communication system, and a mobile communication system, , a multimedia terminal having an m-VoIP call function is detachable from a terminal detachable unit, a package body having a display unit having a size larger than that of the multimedia terminal, or a first processing unit located inside the multimedia terminal, A first folding portion having a wireless web connection function for connecting to the Internet and a web surfing function and connecting one side of the package body and the terminal detachable portion in a folding manner so that the package body and the terminal detachable portion are connected and opened like a wing , Two pairs of toothed wheels around the four ends of the upper and lower sides of the H-shaped fixed hinge shaft And a second folding portion formed to be folded or unfolded to rotate in either a forward direction or a reverse direction by being engaged with one side of the extension portion extending the function of the multimedia terminal and the one side of the package body, M-VoIP communication method using a serial bus wire communication in which a front surface of a display unit is folded to cover a front surface of the display unit, thereby making it possible to carry out a selection in a notebook type or a tablet type while being portable in a display unit size. Package.

In order to achieve the above object, according to the present invention, there is provided a mobile terminal comprising: a first processor having a wireless web connection function and a web surfing function for connecting to a wireless Internet network using a mobile IP; A second processing unit provided in the multimedia terminal to enable m-VoIP communication through the function; (Hereinafter referred to as a " serial communication cable ") of communication signal lines according to the serial bus data transmission signal standard; And activating the wireless web connection function in the first processing unit and the m-VoIP calling function in the second processing unit to establish mutual data communication through the serial communication cable; And at least one selection menu for operating the m-VoIP call function to the multimedia terminal, and an m-VoIP call through the wireless Internet network is provided with a screen for displaying an operation status according to the selection menu Characterized in that the m-VoIP communication method using serial bus wired communication and the processing apparatus portable package according to the present invention are characterized by comprising:
