BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention and the manner of achieving them will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Is provided to fully convey the scope of the invention to those skilled in the art, and the invention is defined by the scope of the claims.

It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. In the present specification, the singular form includes plural forms unless otherwise specified in the specification. As used herein, the terms " comprises, " and / or "comprising" refer to the presence or absence of one or more other components, steps, operations, and / Or additions. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Each vehicle is equipped with an OBE (On Board Equipment) that can use various services by exchanging information and service messages between the vehicle and the base station or between vehicles using the next generation ITS communication network. Each road is equipped with Road Side Equipment (RSE) that communicates with the OBE, and the RSE exchanges information with a management center that manages the road.

Each OBE has a service message that can be transmitted and received according to its own class. For example, an OBE mounted on a general vehicle can not transmit a message such as an emergency vehicle information message (siren) service, but a special vehicle such as a police car or an ambulance can be transmitted. In addition, cargo trucks can send and receive information for cargo tracking services.

The present invention enables the efficient use of the vehicle communication network by confirming and processing the service that can be transmitted and received through the authentication procedure between the OBE and the RSE based on the difference of the services that can be transmitted and received for each vehicle.

FIG. 1 is a flowchart illustrating a process of authenticating an OBE by a vehicle network authentication and message transmission / reception method according to an embodiment of the present invention.

When the OBE of the vehicle is driven (vehicle start, etc.), the OBE of the vehicle is connected to the RSE located around the vehicle to communicate with each other (S100), and the network entry and authentication procedure is performed through the corresponding RSE. RSE is linked to a management center that performs authentication and vehicle management.

In the process of confirming the validity of the identifier received from the OBE, if the OBE registers an identifier capable of identifying itself in the center via the RSE, the center determines the identifier of the OBE (S120) And so on. The OBE identifier is registered in the center in advance, or contains the necessary information in the identifier.

The center examines the OBE identifier to determine the validity of the OBE, and if the validity is recognized (S130), the center assigns the authentication information to the OBE (S140). The process of assigning the authentication information to the OBE can be performed through the RSE as well as the center. At this time, the RSE communicates with the center, verifies the validity of the OBE, and assigns the authentication information to the OBE when the validity of the OBE is confirmed.

 The authentication information allocated to the OBE includes terminal class (information on the type of vehicle - passenger / commercial, small / medium / large size, cargo truck, bus / minibus, special car, police car, ambulance, And associated requirements, service identifiers and related requirements that must be sent, class of receivable terminals, service identifiers and related requirements, terminal classes that must be received and processed, service identifiers, and related requirements.

Service related requirements include transmission power, transmission message length, transmission rate, transmission period, number of transmission repetitions, data elements to be stored (other than data elements can be assigned to fixed values and range values) And methods (eg, driver warning, direct vehicle control, etc.).

Based on this allocation information, the OBE uses allocated services among various implemented services.

If the validity of the identifier of the vehicle OBE is not confirmed by the above-described authentication process, the RSE transmits an unauthentication notification message to the OBE of the vehicle (S150). Upon receiving the unauthentication notification message, the OBE turns off the vehicle and stops the vehicle from running or periodically broadcasts a message informing that the vehicle is an unauthorized OBE. Unauthorized OBEs can not transmit regular service messages, but only receive them.

FIG. 2 is a flowchart illustrating a process of RSE processing a message received from an OBE of a vehicle by a vehicle network authentication and message transmission / reception method according to an embodiment of the present invention.

When the RSE receives a specific message from the OBE of the vehicle (S200), the RSE receives the authentication information for the OBE from the center (first time) and checks the authentication information to determine whether or not it is a message that the OBE can transmit (S210).

Whether the specific message is a message that can be transmitted by the corresponding OBE can be determined by checking whether the assigned authentication information matches the authentication information of the corresponding OBE (S220) and whether the corresponding message satisfies the service-related requirements (S230 ). If the OBE identifier is not valid, the OBE does not support the assigned terminal class, the OBE does not support services that must be sent / received, or the OBE does not satisfy the service-related requirements The OBE recognizes that it is a message that can not be transmitted by the OBE.

If it is determined that the OBE can transmit the message, the corresponding message is processed according to the contents of the service message (S240). If the authentication information does not match, the center notifies the center of the fact (S250) (S260). The center operator can cope with such situation by various methods according to the policy such as vehicle remote control and movement route tracking.

FIG. 3 and FIG. 4 are flowcharts illustrating a process of transmitting and receiving a message by OBE of a vehicle according to a vehicle network authentication and message transmission / reception method according to an embodiment of the present invention.

The OBE must transmit the relevant information according to the relevant requirements when an event related to the service to be transmitted occurs. In the case of the service that can be transmitted, the OBE must transmit the information according to whether the service is implemented, user setting, And method. In addition, if a service message to be received must be received, the corresponding message must be processed in accordance with the related requirements. In the case of a service message that can be received, whether or not to process the service message, user setting, and related requirements is determined.

FIG. 3 shows a process in which a vehicle OBE transmits a message. When a specific event is generated in the vehicle (S300), the OBE determines whether the information about the event is transmitted based on the assigned authentication information, system information, And method.

Since the transmission of the message can be performed only by the authenticated OBE, when the event occurs, the authentication information allocated to the OBE is checked (S320), and it is checked whether the corresponding event is included in the service class to be transmitted (S340) If it is included, a message for the event is transmitted (S380).

If the event is not included in the service class that must be transmitted (S340), it is checked whether the event is included in the service class that the OBE can transmit (S360). If the event is included in the service class that can be transmitted, (S380).

FIG. 4 shows a process of receiving a message from the OBE of the vehicle. When a specific service message is received in the vehicle (S400), the OBE determines whether the corresponding message is processed based on the assigned authentication information, system information, Determine the method.

When the OBE of the vehicle receives the message, the authentication information allocated to the OBE is checked (S420), and it is checked whether the message is included in the service class to be received (S440). If it is included in the service class to be received, (S480). ≪ / RTI >

If the message is not included in the service class that should be received (S440), it is checked whether the corresponding message is included in the service class that the OBE can receive (S460). If the message is included in the service class that can be received, The requirements are processed (S480).

As described above, according to the present invention, only messages that have undergone the authentication procedure are transmitted and received in the OBE of the vehicle, unnecessary resource waste can be prevented and the possibility of accident occurrence due to erroneous information transmission can be reduced.

The foregoing description is merely illustrative of the technical idea of the present invention and various changes and modifications may be made without departing from the essential characteristics of the present invention. Therefore, the embodiments described in the present invention are not intended to limit the scope of the present invention, but are intended to be illustrative, and the scope of the present invention is not limited by these embodiments. It is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents, which fall within the scope of the present invention as claimed.
