The present invention relates to a system and a method for providing DMB-based user request telematics content, and more particularly, to a structure of a message for requesting a desired content to a TSP and analysis of the message to provide the requested content. The present invention relates to a content providing system and a method for proposing a structure so that a user can request and receive desired content.

Recently, due to the remarkable development of mobile communication technology, the vehicle environment, which has been disconnected from the outside, can use various telematics services through WLAN and CDMA off-board wireless communication devices. In addition, telematics service users want to receive real-time information through a mobile communication network, rather than using information stored in a terminal in a typical telematics service route guidance service, location-based service and entertainment services. In addition, DMB broadcasting enables stable and high-quality digital video / audio / data services even in high-speed moving bodies such as vehicles, and the movement to fuse them with telematics is rapidly developing.

In the present invention, among the telematics contents provided through the existing CDMA communication network, traffic information, weather information, surveillance camera location information, POI, and the like, are targeted to contents that can be commonly used by unspecified users. When the telematics contents are provided through the existing CDMA communication network, personalized and only necessary information is received, so that the customized telematics service is possible.However, in order to provide such services, a communication for a telematics terminal is provided separately from a mobile phone carried by an individual. The problem is that the module must be purchased and maintained. In addition, due to frequent communication with the Telematics Service Center (TSP) and download of contents in order to receive telematics services, the burden on the communication fee of data is increasing.

Since conventional CDMA bidirectional communication basically assumes a TCP / IP connection, the traffic generated when multiple users are accessed at the same time should be considered. Thus, the telematics service center increases the cost of building and maintaining the system in the center. Therefore, for low-cost telematics service, it is necessary to diversify communication channels and select communication channels according to the characteristics of contents. For example, while personalized services use existing CDMA broadcasts, it is preferable to transmit contents through which the user is expected to use them in common, such as traffic information and weather information, through a broadcasting network. However, if the vehicle passes through the shaded area, two-way communication can be retransmitted after the interruption. However, since the DMB broadcasting network is based on communication, it is impossible to implement such a mechanism. Therefore, in the broadcasting network, the same data is retransmitted several times at regular intervals, but the reception rate is improved.

The existing telematics content providing system through the DMB simply plays the collected traffic information in the TPEG message and delivers it to the terminal. However, as telematics contents are diversified, there may be a problem of sharing a limited bandwidth among various services, and there is a need for providing differentiated services by allocating bandwidth for contents having a large number of user requests.

Therefore, this patent proposes a structure of TSP and DMB center to give priority to contents by analyzing the structure of the message for requesting the user's desired contents to the TSP and to provide the requested contents. It wants to be provided by requesting the desired content. In particular, in the case of the current content providing service through DMB broadcasting, there is a disadvantage in that the user does not receive the desired content, but by using the present invention, the bandwidth is efficiently used by transmitting the information requested by the individual in the margin of the existing broadcasting bandwidth. At the same time, it is possible to provide differentiated services by region and service.

When telematics contents such as traffic information, weather information, and POI are provided through the existing CDMA communication network, the burden of data communication charges is increasing due to frequent communication with the telematics service center (TSP) and download of contents. With the commercialization of satellite DMB broadcasting and terrestrial DMB broadcasting, stable and high-quality digital video / audio / data service is possible through DMB broadcasting in high-speed mobile vehicles such as vehicles, and the movement to converge with telematics is rapidly developing. . Therefore, among the telematics contents provided through the existing CDMA communication network, congestion information, notice information, safe driving information, news information, POI, etc., which are not personalized and can be commonly used by many unspecified users, use the data service channel of the DMB network. Efforts are being made to transmit the data, and the TPEG TTI specification for this purpose is standardized and commercialized.

 Therefore, the present invention, when transmitting telematics content such as congestion information, notice information, safe driving information, news information, POI, etc., which are defined in the TPEG specification through the DMB broadcasting network, make the best use of the limited broadcast bandwidth for broadcasting requested by users. The present invention proposes a technique for additionally transmitting telematics content.
