Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 illustrates a system for providing a DMB broadcasting public relations service using a CBS according to an embodiment of the present invention. The broadcasting public relations service providing system according to the present invention includes a DMB broadcasting system 400, a DMB broadcasting public relations service server 200, a mobile DMB terminal 100, and a wireless data network system 300.

The DMB broadcasting system 400 uses a DMB broadcasting station 410, a terrestrial antenna, a satellite antenna, and the like to DMB broadcast signals by multiplexing video signals, audio signals, and data signals of a plurality of DMB broadcasting channels to generate a DMB broadcast signal. And a DMB broadcasting transmitting station 420 which transmits to the terminal.

The DMB broadcasting promotion server 200 connects to a wireless data network system through a communication network such as the Internet and performs a function of generating a DMB broadcasting promotion message (BP_MSG) for a broadcasting program of a DMB broadcasting channel to be promoted. The DMB broadcast promotion message (BP_MSG) is a DMB broadcast promotion service identifier (BP_ID) indicating that the data is for broadcast promotion, the name of the program to be promoted, and the DMB broadcast promotion including information such as the program broadcast time and program end time. Data BP_DATA and DMB broadcast channel information BP_CH specifying a DMB broadcast channel on which a program to be promoted is broadcasted.

The wireless data network system 300 exemplifies a CDMA mobile communication network, a GSM mobile communication network, which mediates communication of a mobile terminal through a base station 320, a broadband wireless Internet network, and a wireless LAN, which mediate communication of a mobile terminal through an access point. In this case, the wireless data network system 300 of the present invention includes a CBS (Cell Broadcasting System), so that a function for broadcasting the same message to a plurality of mobile terminals is required.

SMS transmission method has point to point individual transmission method by short message service, that is, service method by polling, which has advantages of near 100% information arrival rate and one-to-one marketing, but tens of thousands Simultaneous transmission of real-time broadcast information to more than one subscriber is limited, and there is a problem in that a communication cost is expensive due to the use of individual information because of individual transmission methods. In addition, overloading SMS messages can increase the load on the exchange and increase traffic on the paging channel, which can adversely affect basic services. However, CBS is able to deliver the same contents to multiple subscribers by sending a single message in a point-to-multi-point nature, minimizing network load and increasing traffic on the paging channel, which is advantageous for accommodating a large number of subscribers. Do. In addition, the exchange, control station, and base station database table may be managed to provide a location based service (LBS) provided only to mobile communication users in a specific area. CBS has a merit that almost all terminals in a base station can receive data at the same time, rather than a specific terminal, rather than SMS, which provides text information to each person.

2 shows an example of a wireless data communication network in which a CBS is implemented. The wireless data communication network 300 includes a router 313, a wireless data communication network broadcasting server 314, an automatic voice response system (ARS, 315), a cell broadcasting system 310, a hub 311, a cell broadcasting center ( CBC, 312, IGS 316, and exchange center (MSC, 317). The router 313 designates the most efficient path for receiving the DMB broadcast promotion message BP_MSG transmitted from the DMB broadcast promotion server 200, and the wireless data network broadcast server 314 receives the received message via the router 313. Among the messages, information in the form of voice and information in the form of text and image / video are separated and separated.

The automatic voice response system 315 stores information in a voice form separated from the wireless data network broadcasting server 314. The cell broadcasting system 310 stores advertisements in the form of text and images separated from the wireless data network broadcasting server 314.

The cell broadcasting center 312 receives and manages the DMB broadcast promotion message BP_MSG from the cell broadcasting system 310, and transmits the DMB broadcast promotion CBS message BPC_MSG to the exchange center 317. The exchange center 317 receives the DMB broadcast promotion CBS message (BPC_MSG) from the automatic voice response system 315 and the cell broadcasting center 312 in real time and simultaneously through a wireless network via a base station. 100).

Meanwhile, the DMB broadcasting promotion CBS message (BPC_MSG) broadcasted by the wireless data network system 300 may be divided into various channels through customer analysis. For example, gender (male / female) classification and age group (10s, 20's, 30's, 40's, 50's, etc.) or by registering the broadcast category specified by the viewer and assigning channels to each category to receive DMB broadcasting promotion CBS messages (BPC_MSG) By selectively transmitting, more detailed and centralized broadcasting promotion can be performed.

The header HEADER means header information added to the DMB broadcast promotion message BP_MSG received from the DMB broadcast promotion server 200 according to the CBS message format. The DMB broadcast PR service identifier BP_ID is identification information indicating that the received data packet is a data packet for the DMB broadcast PR service. The FLAG field is a data field for providing a more detailed broadcast promotion service. For example, in the case of a broadcast promotion service segmented for each channel, the flag FLAG indicates a corresponding channel or activates a vibration function. It can be used as a control code for controlling a specific function.

 The DMB broadcasting channel information (BP_CH) is code information allocated to a channel on which a broadcast program to be promoted is broadcasted. Similar to a call back telephone number of a conventional SMS message, the DMB broadcasting channel information (BPC_MSG) When the viewer wants to watch the broadcast channel according to the reception, it plays a role of receiving the broadcast channel immediately without a separate channel manipulation or channel search. The LENGTH field performs a function of dividing the DMB broadcast promotion data BP_DATA into several CBS messages when the DMB broadcast promotion data BP_DATA to be described later exceeds the amount of transmission data defined by the CBS. .

DMB broadcast promotion data (BP_DATA) is a field that contains the actual content of the broadcast promotion may include the content of the broadcast program name, broadcast start time, broadcast end time, broadcast plot summary, etc. In addition to text data, images, audio, Various data such as video can be accommodated.
