INTERNET ADDRESS GENERATION AND ACQUISITION METHOD OF VEHICLE NUMBER}

The present invention relates to a method for generating and obtaining an Internet address of a vehicle number.

Typically, IP (Internet Protocol) addresses currently in use are operated in 32 bit (Bit).

This means that the world's IP addresses are limited to 2 ^ 32, or 4 billion.

All future systems (mobile phones, washing machines, boilers, vehicles, etc.) are embedded systems, all moving forward with their own unique IP.

For reference, it is not possible to assign each IP to an individual embedded system.

An embedded system is a system that is designed with a microprocessor that acts as the brain of a mechanical or electronic device, allowing effective control.

In other words, the software (operating system) that operates the device does not read from disk like a computer, but rather a device embedded in a chip.

As described above, the IP address limited to the embedded system is difficult to handle, and a new IP operating system has been introduced.

Now is the transition from the old IP system (IPv4) to the new IP system (IPv6), and this process will create 2 ^ 128 usable IPs.

All mobile phones, washing machines, TVs, etc. are going out with unique IP systems, and in fact, they are already being applied to refrigerators and boilers.

Today's vehicles are not only a means of transportation for users, but in the future, telematics terminals are becoming a perfect Internet host through wireless Internet service, and Wireless Application Protocol (WAP) is a major means of providing wireless Internet service. ) Is transforming into an IP-based protocol.

In other words, telematics terminals are becoming more than just a service access tool but a perfect Internet host.

This will be even more important for the future Internet experience, and it is more valuable to map vehicle numbers to IP addresses.

An object of the present invention is to provide a method for generating and obtaining an Internet address of a vehicle number that can be controlled or communicated through the Internet by IPv6 Internet addressing a vehicle number of a license plate attached to a vehicle.

In order to achieve the above object, the present invention is equipped with a telematics terminal capable of automatically generating an IPv6 address in an IPv6-based Internet communication environment, and serves as a direct Internet host, and a vehicle through an Internet host using IPv6. CLAIMS 1. A method for generating numbers by IPv6 Internet addressing, the method comprising: reading a vehicle number of a telematics terminal by an IPv6 protocol engine; Converting the area codes constituting the vehicle number of the telematics terminal and each decimal number into a 4-bit binary format; Padding a specific bit in the converted binary bit string to generate an interface ID having a predetermined size; And combining the generated interface ID and prefix information to generate an IP address.

In addition, to achieve the above object, the present invention provides a method for obtaining an Internet address of a vehicle number, the method comprising: detecting an IP address request of the vehicle number name address; Recognizing a server address for managing a DNS of a corresponding country using a country identification number of the vehicle number name address; Accessing the recognized DNS server of the corresponding country and recognizing the address of the server managing the DNS of the corresponding area by using the area identification number of the vehicle number name address; And accessing the recognized DNS server of the corresponding region and recognizing the IP address of the corresponding subscriber vehicle using the subscriber vehicle number of the vehicle number name address.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. While many specific details, such as the following description and the annexed drawings, are shown to provide a more general understanding of the invention, these specific details are illustrated for the purpose of explanation of the invention and are not meant to limit the invention thereto. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

An embodiment of the present invention is a method for arbitrarily controlling or communicating a vehicle using the Internet so as to be suitable for an upcoming All-IP network by IPv6 Internet addressing a vehicle number of a license plate attached to a vehicle.

This paper describes how to automatically generate IPv6 unicast address in next generation Internet communication environment based on IPv6 and how to find 128-bit IPv6 address from DNS (Domain Name System) which is pre-assigned for name address consisting of vehicle number. will be.

Automatic address generation is about how an Internet host can create its own IP address for use as a sender of an IP packet, and a search from DNS refers to the process of finding the recipient's IP address.

An embodiment of the present invention relates to a method of automatically generating a sender's IP address based on a vehicle number and searching for a recipient's IP address using DNS, and a concept of mapping a vehicle number to DNS using IPv6. Suggest.

Embodiments of the present invention relate to a method of automatically generating an IP address for internet communication using a vehicle number and a method of obtaining an IP address from a DNS in which an IP address arbitrarily assigned by an address management system is stored and managed.

The 128-bit IPv6 address consists of a combination of 64-bit subnet prefix information and an interface ID, as shown in FIG.

The subnet prefix information is information allocated externally by the Internet communication network management regulation, and the interface ID is information automatically generated by using identifier information provided to the network interface card.

This method of automatically generating interface IDs is defined in the Internet standard RFC 2373 standard.

In order to give an IP address to a vehicle and act as a direct Internet host in a next generation Internet communication environment based on IPv6, the vehicle's telematics terminal should be able to automatically generate an IPv6 address like other Internet hosts.

2 is a data structure system diagram for a vehicle number.

The embodiment of the present invention has a view of mapping a vehicle number to an IP address because the telematics terminal of the vehicle is regarded as a small Internet host capable of accommodating various services on the Internet.

For reference, the vehicle number consists of a system of area code, application code, and serial number in Korea, and adjusts the number of bits allocated according to the number of each number component.

The area code is 2 digits for the vehicle, so allocate 8 bits.

32 bits are used (+ alpha (diplomacy, consul, quasi-diplomacy, national flag, agreement representative, etc.), so allocate 5 bits.

Since the serial number consists of four decimal numbers, 16 bits are allocated.

The vehicle number-based 64-bit interface ID is used to add unicast IPv6 addresses with prefix information.

Then, the 64-bit telephone number interface ID generated in the above procedure is combined with the prefix information assigned during the IPv6 protocol operation.

Once these steps are completed, the automatic generation of IPv6 unicast addresses for the telephone handsets is complete.

The Internet host can send IP packets using this address as a sender.

First, as a basic precondition,% is used as an identifier for identifying an address using a vehicle number.

For example, an address using a vehicle number can be represented as% 35M1234.

3 to 5, a method of automatically generating a sender's IP address based on a vehicle number and searching for a receiver's IP address from a DNS according to an embodiment of the present invention will be described.

Here, the automatic generation of the Internet address refers to the Internet host making itself an IP address to be used as a sender of the IP packet, and the automatic acquisition of the Internet refers to searching the recipient's IP address.

Currently, a method of finding an IP address based on a domain name address using DNS is used. However, a method of finding an address using a vehicle number has not been developed yet. It's much more convenient to find the IP address by car number rather than by finding it.

3 is a flowchart illustrating a method of automatically generating an IPv6 Internet address using a vehicle number according to an embodiment of the present invention.

Referring to FIG. 3, a vehicle equipped with a telematics terminal capable of automatically generating an IPv6 address in an IPv6-based Internet communication environment and serving as a direct Internet host, and IPv6 Internet addressing of a vehicle number through an Internet host using IPv6 It describes how to generate.

First, the IPv6 protocol engine reads the vehicle number of the telematics terminal (S310).

Subsequently, the area code (8 bits), application code (5 bits) and each decimal number constituting the vehicle number of the telematics terminal are converted into a full 29 bit binary format of 4 bits (4 bits * 4 digits = 16 bits). (S320).

In operation S330, an interface ID having a predetermined size is generated by padding a specific bit in the converted binary bit string.

For example, the padding operation adds zeros to the uppermost positions until it becomes 64 bits in the created bit string.

Subsequently, the generated interface ID and the prefix information are combined to generate an IP address (S340).

That is, the 64-bit telephone number interface ID is combined with the prefix information allocated during the IPv6 protocol operation.

According to the internet address generation method of the vehicle number, an IPv6 unicast address for the vehicle number is automatically generated (S350).

4 is a flowchart illustrating a method of obtaining an IP address using a vehicle number according to an embodiment of the present invention, and FIG. 5 is a diagram illustrating a method of obtaining an IP address from a domain name server (DNS) for a vehicle number according to an embodiment of the present invention. A diagram illustrating the process.

A method of obtaining an internet address of a vehicle number will be described with reference to FIGS. 4 and 5.

First, the IP address request of the vehicle number name address is detected, the region of the IP number to be accessed is identified using the vehicle number name address, and the server address managing the DNS of the corresponding country is recognized.

Next, access the DNS server of the recognized country, recognize the address of the server that manages the DNS of the region by using the region identification number of the vehicle number name address, and access the DNS server of the recognized region The IP address of the corresponding subscriber vehicle is recognized by using the subscriber vehicle number of the name address.

Here, the step of recognizing the IP address of the vehicle is as shown in FIGS. 4 and 5.

First, the client node allocates an IP address for address% 35MA1234 to DNS server A (S410).

The requested DNS server A determines that the vehicle is in the form of a name number in the form of a vehicle number through a% display, and determines whether the vehicle has a set vehicle identification number (S412, S414).

If the form having the set vehicle identification number, DNS server A requests the IP address for the address% 35 Ma1234 address to the root DNS server (S416).

The root DNS server informs DNS server A of DNS server A, which manages area codes such as Seoul, through area identification number 35 in response (S418).

DNS server A requests the local name DNS server B an IP address for address% 35MA1234 (S420).

DNS server B responds to DNS server A, DNS server C, which manages the symbol “e” through the symbol “e” (S422).

DNS server A requests DNS server C for an IP address for address% 35MA1234 (S424).

DNS server C searches the vehicle number database and responds to the assigned IP address (S426).

The DNS server A responds to the client node that requested the DNS service with the received IP address (S428).

On the other hand, if it is not the name address of the vehicle number format in the above (S412), DNS server A performs a conventional name address search process (S430).

As described above, the method for generating and obtaining an Internet address of a vehicle number according to the present invention can be arbitrarily controlled or communicated using the Internet by converting a vehicle number of a license plate attached to a vehicle into an IPv6 Internet address.

In addition, IPv6 unicast address is automatically generated in the IPv6-based internet communication environment, and the 128-bit IPv6 address, which is pre-assigned for the name address composed of the vehicle number, can be found from the DNS.
