Description

Telematics middleware system and service providing method using the same {A system and a method for controlling telematics middleware}

The present invention relates to a telematics middleware system, and more particularly, a telematics middleware system for smoothly performing a service process between a telematics terminal of a vehicle and an information center by receiving multimedia data from a satellite or terrestrial digital multimedia broadcasting (DMB) transmitter. And it relates to a service providing method using the same.

Telematics is being provided to vehicles to provide intelligent computing environments based on mobile computing technology.

Telematics uses traffic positioning systems (e.g. Global Positioning System) and wireless networks to inform drivers and / or passengers of traffic information, emergency response, remote vehicle diagnostics, internet access (e.g., financial transactions, news). , A mail system, etc.), a telematics system includes a telematics provided in a vehicle, a content providing server for providing content to the telematics, and a wireless network connecting the telematics and content providing server. It is composed.

The telematics system includes a content providing server that provides contents to the telematics on a wireless network to which a telematics service for providing a telematics service to a driver's vehicle is provided, and requests information and / or data to a content server through a wireless network. In addition, the content server includes a problem in that there is only one-sided information and / or data flow for providing information and / or data corresponding to the request to the telematics provided in the vehicle through the wireless network.

Recently emerging telematics is a new concept of vehicle wireless internet service that combines automobile and wireless communication. It is a compound word of communication and information technology. It is also called 'automatic telematics' in that it uses an auto PC that can search for various kinds of information.

The driver can remotely diagnose the vehicle over the wireless network, use the auto PC equipped with a wireless modem to access traffic, living information, emergency rescue, etc., send phone messages to offices and friends, as well as voice e-mail. You can send and receive and download audio books.

Telematics has a tremendous impact on the off-line industry, from the mobile communications industry to the automotive industry, system integration (SI), content, handset industry, insurance, used cars, parts, car rental and vehicle maintenance.

As such, Telematics is a comprehensive service that provides various information required by users based on domestic high-speed Internet infrastructure (infra) using mobile communication terminal technology and various wireless access technologies. Therefore, existing Geographical Information System (GIS) / LBS The connection with various additional services such as Location-Based Service (ITS) / Intelligent Transprot System (ITS) is the most important.

To this end, the information collection network and the information distribution network must be configured using the wireless communication technology of the second generation mobile communication network. Second generation mobile communication technology that provides voice and low speed data services has evolved into the third generation and fourth generation, and advanced cellular mobile communication technology is being introduced to provide multimedia services. Therefore, in order to provide a telematics service, a high speed wireless network in a vehicle is really needed.

In the conventional telematics middleware system configuration, as shown in FIG. 1, when the terminal (mobile phone, PDA, etc.) 2 requests a road guidance service from the information center 6 side, the telematics middleware 4, that is, the data transmission program, the terminal. The request message of MO (Mobile Oriented) is transmitted to the communication server (7a) in the information center, and via the portal server (7b) to the road guidance server (7c).

The route guidance server 7c transmits a response message (MT) for the corresponding request message (MO) transmitted from the terminal 2 to the telematics middleware 4 via the portal server and the communication server, and the telematics middleware ( In 4), the response message MT is transmitted to the terminal 2. For reference, as shown in FIG. 1, the telematics middleware performs message request / response processing, session management, and communication server connection management.

However, due to the characteristics of telematics services in the conventional system, service may not be possible due to a network failure, service may not be possible due to a server failure in the information center, and after the request message is transmitted from the terminal to the information center, the response information may be processed by the information center. However, the terminal has a problem in that it takes a lot of time for data processing and transmission time according to the request when the terminal fails to receive the response message.

The problem to be solved by the present invention is to solve the problems of the prior art, an object of the present invention is to respond to the response message of the road guidance server in the telematics middleware to facilitate the service process between the telematics terminal and the information center while the vehicle is running It is to provide a telematics middleware system that can be used as a database (DB) to use the response message in the DB when the service re-request in the terminal.

In addition, the present invention enables simple and easy standard / universal protocol-based centralized control, monitoring, interworking between systems, and centralization to easily and flexibly develop and operate telematics services such as safety and security. Through advanced service control, messaging and security, and interworking of heterogeneous systems, another system only needs to send a message to the service bus, thereby providing a flexible and easy service.

In addition, the telematics middleware system of the present invention is a lightweight, easy, general-purpose, standard by configuring the ESB based on the REST, the service system can be integrated development and service in REST, by adding only the relevant filter when additional heterogeneous integration, filtering, and control It can be extended and modified, and serves as REST server and client, which are standard / universal protocols, so that development and debugging can be done even before the target system is developed. There is another purpose to make communication possible.

The response message is stored in the database unit DB, but the latest response message of the response message is also stored in the memory unit so that the response message can be read from the memory unit when a request message (MO) is requested from the terminal. The load on the system can be reduced.

After the response message (MT) is transmitted to the corresponding terminal, it is determined whether the terminal receives data (S60). That is, when data reception is normally performed in the terminal, data transmission and reception are completed (S70). If data reception is not normally performed, a message (MO) is re-requested (S80).

In step S80, when the message is re-requested from the terminal, the telematics middleware immediately calls the response message MT stored in the database unit and transmits the response message MT stored in the database unit to the corresponding terminal (S90).

In the present invention, when a message is requested from the terminal, a corresponding response message is transmitted. However, when a message is requested from the terminal and the message is requested again, the corresponding response message stored in the database or database of the telematics middleware is used. I would have to.
