The portable communication terminal generally does not completely shut off the power, and is usually in the reception standby mode. With this feature, in case of the integrated communication / broadcasting terminal, a very short signal (disaster occurrence notification signal) indicating only the occurrence of a disaster is transmitted through a wireless communication network that is difficult to deliver many messages at the same time. By turning on the power of the broadcast receiver to receive the disaster broadcast, it is possible to effectively reduce the power consumption according to the additional device for receiving the disaster broadcast in the standby mode of the broadcast terminal. This also overcomes the shortcomings of "wireless communication technology" and "broadcasting technology" in relation to disaster alerts, and makes use of their advantages.

Hereinafter, the present invention will be described in detail with reference to FIG. 1.

In FIG. 1, the disaster prevention center 100 collects and produces disaster information to provide disaster information to the integrated communication / broadcasting terminal device 130 using the broadcasting network 110 and the wireless communication network 120. In other words, the disaster prevention center 100 broadcasts disasters and at the same time, disaster broadcasts are started with very short messages using functions such as CBS (Cell Broadcasting Service) of the wireless communication network (that is, disasters are occurring). Informs the integrated communication / broadcasting terminal device. This enables immediate notification of disasters not only in large areas but also in narrow areas at the cell level without network congestion. In other words, it enables local disaster broadcasting, which is a problem in disaster alert using broadcast networks.

Here, the broadcasting network 110 refers to a broadcasting network such as a DAB network and a DMB network (T-DMB, satellite DMB network, etc.) capable of simultaneously delivering a large amount of multimedia disaster information to a plurality of integrated communication / broadcasting terminal devices 130. In addition, the wireless communication network 120 is a general wireless network in the present invention to deliver a short disaster information through this network.

Meanwhile, the integrated communication / broadcasting terminal device 130 for receiving a disaster broadcast according to the present invention receives a signal transmitted through the broadcasting network 110 and the wireless communication network 120 to show and hear disaster information to a user. And the like, and include a wireless communication transceiver 131, a broadcast reception / channel controller 132, a broadcast signal receiver 133, a disaster alert generator 134, a power supply 135, and a display 136. Here, the broadcast reception / channel control unit 132 is composed of a broadcast reception switch 1321 and a 'broadcast reception switching and channel control unit' 1322.

That is, the integrated communication / broadcasting terminal device 130 for receiving a disaster broadcast receives a very short signal (disaster occurrence notification signal) indicating only the occurrence of a disaster transmitted through a wireless communication network, and uses the signal to receive a broadcast signal receiver ( When the user is not receiving a broadcast, the power is turned on and the disaster broadcast channel is automatically selected so that the disaster broadcast can be received immediately after the disaster broadcast starts.

First, the wireless communication transceiver 131 has a general wireless communication transmission and reception function, in particular, receives a disaster occurrence notification signal transmitted through a wireless communication network, and also through the two-way communication with the disaster prevention center 100 disaster party information (disaster Additional information related to prevention, the current situation of the party affected by the disaster, etc.) to the disaster prevention center 100, or to receive disaster response information (available through a broadcasting network or a communication network) from the disaster prevention center 100; To perform. Here, the disaster occurrence notification signal is a communication signal including the disaster occurrence information means a very short signal indicating the presence of a disaster. This may include information on disaster broadcast channels that are being broadcast. If there is a dedicated channel for disaster broadcasting, it may not be included. The disaster notification signal may be transmitted through a wireless communication network according to a CBS function.

The broadcast signal receiving unit 133 has a general broadcast signal receiving function, and in particular, receives a disaster broadcast signal transmitted through the broadcast network 110, and also facilitates the disaster prevention center 100 through a communication network while the user receives the disaster broadcast. One-touch to connect additional information on disaster prevention and the current situation of the party in disaster to the disaster prevention center 100, or to receive a countermeasure (available through a broadcasting network or communication network) from the disaster prevention center 100 By providing an automatic connection point with the disaster prevention center 100 by. That is, the broadcast signal receiver 133 extracts connection information (which may include connection information to the disaster prevention center agent) included in the disaster broadcast signal and transmits it to the wireless communication transceiver 131. do. The wireless communication transceiver 131 performs the automatic connection to the disaster prevention center by using the disaster prevention center connection information received from the broadcast signal receiver 133, through which the user can receive the disaster broadcast conveniently and quickly. Disaster situation information can be sent to the disaster prevention center (100) and also can receive the response information about the disaster from the disaster prevention center (100).

In addition, the broadcast signal receiver 133 is cut off from the power supply unit 135 while the broadcast is not being received in order to minimize power consumption. When the wireless communication transceiver 131 receives the disaster occurrence notification signal, power is supplied. And drive. In more detail, this process is as follows.

The broadcast reception / channel control unit 132 controls the power supply and channel selection so that the broadcast signal receiver 133 receives the disaster broadcast signal when the disaster occurrence notification signal is received from the wireless communication transceiver 131. Perform. That is, the broadcast signal receiver 133 in the "OFF" state because the power is not supplied from the power supply 135 is connected to the power supply 135 under the control of the wireless communication transceiver 131 receiving the disaster occurrence notification signal. Drives to perform the broadcast receiving function. The broadcast reception / channel control unit 132 is composed of a broadcast reception switch 1321 and a 'broadcast reception switching and channel control unit' 1322, and the 'broadcast reception switching and channel control unit' 1322 is a wireless communication transceiver 131. Receives a disaster notification signal and controls the broadcast reception switch 1321 accordingly. As a result, the power of the power supply unit 135 is supplied to the broadcast signal receiver 133 to drive the broadcast signal receiver 133. In addition, when the broadcast reception switching and channel control unit 1322 includes the disaster broadcast channel information in the disaster occurrence notification signal, the broadcast signal receiving unit 133 controls the broadcast channel to be selected according to the information. If there is a certain 'dedicated' channel in relation to broadcasting and the disaster occurrence notification signal includes only information on the presence or absence of a disaster, channel control is performed so that a predetermined dedicated channel known in advance is selected. On the other hand, the broadcast receiving switch 1321 performs a function of opening and closing the connection between the broadcast signal receiving unit 133 and the power supply unit 135 under the control of the 'broadcast reception switching and channel control unit' 1322. The user may receive a desired broadcast at any time through the broadcast reception switch 1321. When there is no broadcast reception request of the user, the broadcast reception switch 1321 blocks the connection between the power supply unit 135 and the broadcast signal receiving unit 133. I'm doing it.

If the wireless communication transceiver 131 receives the disaster occurrence notification signal while the user is receiving the general broadcast through the broadcast signal receiver 133, the broadcast signal receiver 133 is already supplied with power. Only the channel control needs to be performed.

Meanwhile, the disaster alert generator 134 analyzes the disaster broadcast signal received by the broadcast signal receiver 133 and generates an alarm signal according to the disaster situation information. That is, the disaster alarm generation unit 134 uses an emergency situation information such as emergency level, type of disaster, disaster location, disaster time, disaster message, etc. For example, in an emergency situation, a large warning message may be sounded, and in a lesser case, the information may be collected and put into a message storage box.

Meanwhile, the display unit 136 displays information (for example, disaster response information, etc.) included in the disaster broadcast signal received from the broadcast signal receiver 133 or the communication signal received from the wireless communication transceiver 131. Perform the function. Here, the display unit is a concept including an image output, an audio output.

2 is a flowchart illustrating a method for receiving a disaster broadcast in a portable small communication / broadcast integrated terminal according to the present invention. Since it has already been described in detail in FIG. 1, the following description will focus on the overall process.
