In general, DMB (digital multimedia broadcasting) is a broadcasting service that provides various multimedia signals such as voice and video to a fixed, portable, and vehicle receiver digitally. A compact disk (CD) is provided through a personal digital assistant (PDA) or a vehicle terminal while moving. ) And digital video disc (DVD) class high quality and high definition broadcasting, and there are three systems such as system A, Dh, and E. At this time, the system A follows the European Digital Broadcasting Standard (OFDM: Orthogonal Frequency Division Multiplexing) of digital satellite broadcasting and terrestrial digital multimedia broadcasting (DMB), and the system Dh is based on the terrestrial DMB, but accommodates the satellite DMB. The system E adopts a code division multiple access (CDM) which is almost the same as the code division multiple access (CDMA). In recent years, such a DBM is combined with a mobile communication terminal and has a state-of-the-art broadcasting environment that changes from a joint viewing to an individual viewing, from a fixed viewing to a mobile viewing, and from broadcasting to a personal casting. In particular, the above-mentioned DMB is divided into terrestrial and satellite waves. Among the satellite DMB, when the program is transmitted to the satellite from the broadcasting center, the satellite spreads it to the DMB terminals throughout the country, and the gap filler is used in the shadow areas such as the inner city where the reception rate is low. Install a repeater called Gap Filler to prevent dropping. On the other hand, the terrestrial DMB is a method of receiving DMB broadcasts using channels VHF 12 and 8 which are currently empty, and receiving a radio wave transmitted from a transmission tower through a terminal.

Then, referring to the mobile communication terminal equipped with the conventional DMB function as shown in FIG. 1, the TV broadcast signal transmitted from the satellite 70 or the transmission tower 71 is received and displayed on the LCD panel 72.

When the character input is completed through the above process, the user of the terminal 73 presses the keypad 76 to select a destination telephone number to be transmitted from the phonebook list stored therein and then presses the transmit button. Then, the terminal 73 transmits the text data input by the user in the SMS message to the base station 74. Accordingly, the SMS message signal of the terminal 73 is input to and stored in the SMS message center 77 via the base station 74 and the MSC 75. Then, the SMS message center 77 checks the destination phone number of the input SMS message and transmits it to the MSC 75. Then, the MSC 75 transmits the SMS message signal transmitted from the SMS message center 77 to the counterpart terminal 78. The counterpart terminal 78 analyzes the received SMS message signal and displays the signal on the display.

On the other hand, when the DMB function is set in the terminal 73 during the above process, the terminal 73 displays the DMB menu on the LCD panel 72. In this case, when the user of the terminal 73 sets a channel to be watched on the DMB menu screen displayed on the LCD panel 72, the terminal 73 transmits the TV channel signal selected by the user to the satellite DMB. In the case of the satellite 70 or terrestrial DMB received from the transmission tower 71 is displayed on the LCD panel 72, so that the terminal user watching TV on the go. Here, if an urgent situation occurs in the process, the base station 74 informs the SMS message of the emergency situation to the terminal 73 or transmits a WAP push message to the terminal 73 to the LCD panel of the terminal 73. (72).

However, the conventional mobile communication terminal equipped with the DMB function is a simple text-based information providing method of simply sending an SMS or WAP push message to the terminal when an emergency or disaster occurs during DMB reception. If the user is not interested in this information, the information cannot be confirmed. Accordingly, the information transferability of the terminal is deteriorated. In addition, there is a problem in that the terminal does not have an appropriate means for informing an emergency situation during a voice call.

Accordingly, the present invention has been invented to solve the above problems, DMB phone users are urgently recognized by the emergency broadcast through the emergency broadcasts to evacuate clearly, thereby maximizing the information delivery of the terminal emergency broadcasting An object of the present invention is to provide a DM terminal with an automatic viewing function and a control method thereof.

Another object of the present invention is to inform the terminal user that a WAP push message indicating the current emergency situation is received when a WAP push message is transmitted from the disaster management system while the terminal is executing voice and other data communication so that the user can take appropriate measures. Accordingly, the present invention provides a DM terminal equipped with an emergency broadcasting automatic viewing function which significantly improves the functionality of the terminal, and a control method thereof.
