SYSTEM AND METHOD FOR TELEMATICS SERVICE OF VEHICLE

The present invention relates to a telematics service system and method for a vehicle, and more particularly, to a telematics service system and method for a vehicle for reducing loads that may occur in a client and a server when a telematics service is processed by a synchronous communication method.

Telematics is a wireless data service that is provided while traveling within transportation equipment such as a vehicle, an airplane, and a ship. In particular, telematics services for automobiles combining mobile communication technology and position tracking technology (GPS) with automobiles are attracting attention.

In the case of a telematics service for a vehicle, a user can install and execute the application on a portable terminal, thereby enabling remote control of some functions of the vehicle regardless of time and place via a wireless network.

1 is a schematic view showing a general telematics service system for a vehicle.

As shown in FIG. 1, the conventional telematics service system for a vehicle includes a portable terminal (client) 10 connected to a vehicle through wired communication or Wi-Fi, a service requested by the portable terminal 10 And a server 20 for connecting a service request and a response between the portable terminal 10 and the vehicle telematics unit 30.

At this time, the server 20 is connected to the client 10 and the automotive telematics unit 30 by wire and wireless communication through a wireless communication base station 40 interconnected by wire communication.

When the service request is generated in the client 10, the server 20 transmits the service request to the vehicle telematics unit 30 to enable the telematics unit 30 to provide the service.

In the past, asynchronous (ASYNC) method was widely used for communication with a vehicle to utilize such a telematics service, but a synchronous (SYNC) method is preferred due to recent development of mobile communication technology and speed.

In the case of using the synchronous (SYNC) communication, the communication result between the vehicle telematics unit and the server (telematics service center) can be known without interruption.

Such a synchronous communication method may be suitable for communication between a client and a server having a high response speed. However, since the response time of a vehicle can not be fast as a server when applied to a telematics service for controlling a vehicle, It can be done inside or outside.

When the response time of the vehicle is delayed, the client waiting method shown in FIG. 2 may be applied, or a thread operating method of the server shown in FIG. 3 may be applied. In the client waiting method, CLIENT 11 waits until a final response is received or a server 22 connecting a service in the middle of a vehicle and a client creates and expands a thread by a thread operating method, Can not keep waiting.

Here, the thread is a kind of virtual memory for service processing. When the service is started, it is generated when the service is started. If the service is needed for processing, it exists in data format rather than reside in the memory of the system.

More specifically, as shown in FIG. 2, when a telematics service is provided by a synchronous communication method to which a client waiting system is applied, the client 11 requests a service to the vehicle telematics unit 31 through the server 21 And waits for a response from the telematics unit 31 afterwards.

As shown in FIG. 3, when the telematics service is provided by a synchronous communication method in which a thread operation method of a server is applied, when the client 12 transmits a service request signal, the server 22 transmits a service request Receives a final response signal of the vehicle telematics unit 32 as an answer to the service request signal sent to the automotive telematics unit 32 after transmitting the response signal to the client 12 to reply that the automobile telematics unit 32 has been completed .

At this time, the server 22 creates a thread before transmitting the service request signal to the vehicle telematics unit 32 and after receiving the final response signal from the vehicle telematics unit 32, Do not keep waiting.

However, both of the above methods load a client or a server. In the case of a thread management method of a commonly used server, when a large amount of services are simultaneously processed according to the performance of a thread management application, In the case of a method in which the client waits, another service may not be available or the service may be abnormally terminated depending on the performance of the client.

Such a situation that the service processing is impossible or abnormally terminated causes the quality of the telematics service to deteriorate and eventually leads to a customer complaint.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention.

[0001] The present invention relates to a telematics service system and method for a vehicle that implements a synchronous (SYNC) telematics service. More particularly, the present invention relates to a telematics service system for a vehicle, And minimizes the system load.

As shown in Fig. 4, the telematics service system according to the embodiment of the present invention can be composed of a client 1, a server 2, and a telematics unit 3 for a vehicle.

The client 1 is a portable terminal that requests a service to the vehicle telematics unit 3 through the server 2, and the user can request a service using the portable terminal.

For example, when the client 1 wants to remotely control some functions of the vehicle, the client 1 requests the service for the remote control to the telematics unit 3 for the vehicle. At this time, the client 1 first requests the server 2 to authenticate the service, It is requested to perform the actual service.

That is, as shown in FIG. 4, the client 1 transmits a primary authentication request to the telematics unit 3 in order to receive a service credential from the server 2 at the time of a service request, (first response) is normally received from the server 2, the user is notified of the normal service processing result (service authentication request success / approval).

At this time, the server 2 does not transmit the primary authentication request of the client 1 to the vehicle telematics unit 3.

The client 1 receiving the authentication (credential) transmits a secondary service request to the server 2 again in order to receive a final response (secondary response) from the vehicle telematics unit 3, at which time the vehicle telematics unit 3) to terminate the service request itself without waiting for a response (secondary response).

The telematics unit 3 that has received the secondary service request through the server 2 sends a final response (secondary response) for the request to the client 1, To the client (1).

At this time, the server 2 transmits the response of the vehicle telematics unit 3 to the client 1 by way of a short message service (SMS) or a push message.

The telematics unit 3 is a control unit mounted in the vehicle, and provides a final response as a result of a service request of the client 1, and communicates with the server 2 by synchronous communication at this time to exchange information , And controls some functions of the vehicle according to a service request received from the server (2).

The server 2 transmits information such as a service request and a response between the client 1 and the vehicle telematics unit 3, and can be configured as a telematics service center.

Here, the server 2 sends and receives the primary and secondary responses to the service requested by the client 1, and provides the result of the requested service through the secondary response.

In addition, the server 2 and the client 1 use HTTP (Hyper Text Transport Protocol) for mutual communication.

Until the first authentication request and the second service request, that is, the process of the primary authentication request, the primary response, and the secondary service request are performed only between the client 1 and the server 2, So that the client 1 can quickly provide the processing result of the service request.

In addition, since the primary authentication request and the secondary service request are separated into separate services on the server 2 side, a thread is not generated between the primary authentication request and the primary service request, .

In the case of the client 1, since there is no need to wait until a final response is received, the load on the client 1 also decreases compared to the conventional one.

The client 1 also receives a primary response from the server 2 (i.e., a process of informing the user of the success of the primary authentication request (approval), a process of transmitting the secondary service request to the server 2 And receiving the secondary response of the vehicle telematics unit 3 through the server 2) as background tasks, and other tasks can be performed in the meantime.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. Modified forms are also included within the scope of the present invention.
