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.

Concept of country information extraction

First, the concept of country information extraction of a user terminal according to the present invention will be described with reference to FIG.

Referring to FIG. 1, a concept of extracting country information of a user terminal according to an embodiment of the present invention will be described. In a user terminal 120 located in a first country (e.g., China) The user terminal 120 may communicate with the server 100 through the network switch 130 and at least one router 140a, 140b, 140c, 140d, And communicates with the server 100 via the communication network 110 of the path. When the user terminal 120 communicates with the server 100, the user terminal 120 may access the server 100 corresponding to the domain name of the server 100 (e.g., 'www.naver.com' in FIG. 1) Lt; RTI ID = 0.0 > 150 < / RTI >

In the present invention, in order to extract country information (for example, China) in which the user terminal 120 is located in the server 100, the network element 120, which is used when the user terminal 120 communicates with the server 100, (E.g., at least one router 140, DNS 150, and the like) from the country information of the corresponding network element, (120) is located.

That is, when the user terminal 120 communicates with the server 100, the user terminal 120 communicates with the user terminal 120 via the various routers 140, (100). For example, in FIG. 1, data transmitted from the user terminal 120 is transmitted through a network switch 130, a router 1 140a, a router 2 140b, a router 3 140c, and a router 4 140d to a communication network 110 to the server 100. Thus, the country where at least some of the routers 140 that initially pass through the user terminal 120 are located is the same country as the user terminal 120. In the case of the DNS 150 communicating with the user terminal 120, if the user terminal 120 is not set to use a specific DNS, the user terminal 120 may communicate with the DNS 150 closest to the user terminal 120 The country where the corresponding DNS 150 is located is likely to be the same country as the country where the user terminal 120 is located.

The country information corresponding to the IP of each router 140 or DNS 150 is stored and managed in a router's IP location DB 160 or other database. For example, by inquiring the IP address '111.191.136.5' of the router 1 140a through the information stored in the router location information database 160, the router 140a is located in 'CN', that is, China . Similarly, by inquiring each IP address of the router 2 140b, the router 3 140c and the router 4 140d through the information stored in the router location information database 160, the router 2 140b, the router 3 140c, The router 140c and the router 4 140d are located in China.

Accordingly, the user terminal 120 acquires the country information of the corresponding location from the IP information of each router 140 and / or the DNS 150, and the country identifier (Country Identifier) And identifies the country where the user terminal 120 is located through the information. In this case, when the country information acquired from the plurality of routers 140 is identical according to the embodiment of the present invention, it is preferable that the country information of the corresponding user terminal 120 is determined as corresponding information, If the country information obtained from the routers 140 of the user terminal 120 does not coincide with the country information of the user terminal 120, the country information of the user terminal 120 can be identified. For example, unlike the one shown in FIG. 1, three of the country information obtained from the four routers 140 passing through the server 100 in the user terminal 120 are identified as being located in China, It is preferable that the country location of the corresponding user terminal 120 is determined as China.

Meanwhile, according to another embodiment of the present invention, when the country information obtained from a plurality of routers is different, the reliability of the country decision can be increased by increasing or decreasing the number of target routers to be measured. For example, when three routers among the country information obtained from four routers 140 are identified as being located in China and one router is identified as located in Korea, the number of measured routers is reduced to three and then measured again . At this time, since the three routers can be information of three routers closer to the user terminal 120 among the information of the four routers (i.e., the router 1 to the router 4) acquired first, Lt; / RTI > On the other hand, by increasing the number of measured routers, more routers can be determined by referring to the information. Another possibility is that the first router (e.g., router 1 140a) in the user terminal 120 is most likely to be closest to the user terminal 120, 120) of the country.

The method for obtaining the information of the routers 140 on the communication path from the user terminal 120 to the server 100 may be variously implemented. For example, it may be acquired using an Internet Control Message Protocol (ICMP) according to an embodiment of the present invention.

The ICMP is a connectionless transmission method for handling a control message for processing errors and changing a transmission path occurring during communication in combination with an internet protocol (IP) in a TCP / IP based Internet communication service, , Which corresponds to the network layer of the OSI (Open Systems Interconnection) basic reference model.

The ICMP commands include 'Trace Router (Trace Router)' and 'Ping (Packet internet groper)'. In addition to the commands listed above, other commands using ICMP or ICMP And IP information of each network element according to the present invention can be obtained. All the above-mentioned schemes are collectively referred to as " ICMP-use "

Meanwhile, in the command using the ICMP, a time to live (TTL) value can be selectively set, and information of routers located in a specific hop can be obtained by adjusting the TTL value. The TTL is a value that is decremented every time a data packet transmitted from the user terminal 120 passes through one hop. If the TTL becomes '0', the corresponding router discards the received packet, Message to the originating host (i.e., user terminal 120) from which the packet was transmitted. For example, when the user terminal 120 sets the TTL to '3' and executes the 'Tracert' or 'ping' command, it returns the IP information about the first three routers to the user terminal 120.

For example, in FIG. 1, when the TTL value of the instruction using ICMP is set to 4, the network switch 130, the router 1 140a, the router 2 140b, and the router 3 140c The user terminal 120 can obtain the IP information for the user terminal 120, i.e., '209.85.241.166', '111.191.136.5', '210.107.53.17', and '211.233.55.86'. The user terminal 120 inquires the received IP information to the router location information database 160 and obtains country information corresponding to each IP. In FIG. 1, since the country information corresponding to the IP information of the three routers including the network switch indicates 'CN', it can be seen that the country where the user terminal 120 is located is China. As described above, the country information corresponding to the IP information for the DNS 150 set in the user terminal 120 is acquired through a database (not shown) mapped with the IP information of the DNS 150 and the country information .

Accordingly, in the user terminal 120, as described above, the ICMP message is transmitted by an application that is automatically activated upon connection to the server 100, and an IP address for at least one router among the routers passing through the ICMP message is acquired And extracts country information matched with the obtained router IP through the router location information database 160 to identify the country where the user terminal 120 is located. In addition, according to another embodiment, the country corresponding to the location of the corresponding user terminal 120 can be identified by extracting country information matching the IP of the DNS 150 accessing from the user terminal 120. Thus, the country information of the identified user terminal 120 is automatically transmitted to the server 100, and the server collects the country information of each user terminal 120 connected thereto. Thus, by obtaining the country information from the network information passed through each user terminal 120 through the method according to the embodiment of the present invention, regardless of whether the user terminal 120 is operated or accessed through an illegal method, Accurate country information of the terminal 120 can be obtained.

Hereinafter, a system and an apparatus according to an embodiment of the present invention will be described with reference to FIGS. 2 and 3. FIG.

Complete system configuration

2 is a diagram showing a configuration of a system according to the present invention. 2, a system according to the present invention includes a service server 200, a communications network 210, a user terminal 220, at least one router 230, a DNS 240, and a router location information database 250 And the like.

First, the service server 200 is a server for providing various information or providing online game services to at least one user terminal 220 connected thereto, and acquires the country information of each user terminal 220 according to the present invention , Restricts the service to a specific country according to the acquired country information or implements various service policies, and can use the acquired country information as advertisement or marketing information for a specific country. The service server 200 is not limited to a specific service purpose or target server but may be any server connected to the communication network 210 to which the user terminal 220 can access the service server 200 of the present invention. .

The communication network 210 may be configured without regard to its communication mode such as wired and wireless, and may be a personal area network (PAN), a local area network (LAN), a metropolitan area network ), A wide area network (WAN), and the like. The communication network 210 may be a known World Wide Web (WWW), and may include a wireless transmission technology used for short-range communication such as Infrared Data Association (IrDA) or Bluetooth Or partially used.

Meanwhile, when the user terminal 220 communicates with the service server 200 through the communication network 210, the user terminal 220 communicates through the at least one router 230 as described above. For example, as shown, the data packet transmitted from the user terminal 220 is transmitted to the service server 200 through the first router, the second router, ..., and the Nth router. At this time, the transmitted data packet is transmitted from the user terminal 220 to the service server 200 after passing the neighboring routers 230 first. Therefore, when the country information on the routers 230 adjacent to the user terminal 220 is acquired, the country where the user terminal 220 is located can be accurately identified even if the user terminal 220 manipulates the country information. If the user terminal 220 does not have a different setting, it communicates with the DNS 240 closest to the user terminal 220. In this case, when the country information of the connected DNS 240 is obtained, the corresponding user terminal 220 ) Of the country. The user terminal 220 obtains both the country information of the routers 230 adjacent to the user terminal 220 and the country information of the connected DNS 240, Can be identified.

A country information extraction application 221 may be installed in the user terminal 220 to identify the country information of the user terminal 220 according to the present invention. The country information extraction application 221 may be provided from the service server 200 and may be automatically installed depending on a specific service program provided to the user terminal 220 from the service server 200, Can be implemented. For example, when the user terminal 220 connects to the service server 200 and executes a specific program, the country information extraction application 221 is automatically executed to collect network information and extract country information.

That is, when the country information extracting application 221 is executed, it automatically executes commands using ICMP (e.g., 'Tracert (Trace Router)', 'ping (Packet internet groper)', etc.) Lt; / RTI > At this time, the destination address of the instruction using the ICMP is set to the service server 200, and a TTL value can be additionally set according to the embodiment of the present invention.

For example, if the user terminal 220 sets the TTL value to 3 and executes the command using ICMP, the 'Tracert' command can be set to 'tracert www.naver.com -h 3', and the 'ping' ping www.naver.com -r 3 '. Meanwhile, the present invention is not limited to the above-mentioned commands, and any command using ICMP is applicable to the present invention. In addition, the present invention is not limited to ICMP, and it is possible to implement using any protocol that can acquire information on the network path to which the user terminal 220 accesses.

In this manner, the country information extraction application 221 can acquire network information using the above-described method or the like, and the network information includes IP information or domain name information of the router 230. In addition, the user terminal 220 receives IP information of the routers 230 adjacent to the user terminal 220 according to the set TTL value. Referring to FIG. 2, when a TTL value is set to be smaller than N and an instruction using the ICMP is executed, the routers 230 corresponding to the information to be acquired belong to the same second country as the user terminal 220.

Next, the country information extraction application 221 inquires of the router location information database 250 to extract country information corresponding to the obtained IP information of each of the routers 230. Meanwhile, in the router location information database 250, IP information about each router and country information on which the router is located are mapped and stored. The router location information database 250 may be located in a separate location as shown in FIG. 2, or may be built in the service server 200. It may also be included in user terminal 220 in other ways.

Accordingly, when the country information for at least one router 230 is extracted according to the above procedure, the country where the user terminal 220 is located is identified. That is, as shown in FIG. 2, since the N-th routers sequentially connected to the first router closest to the user terminal 220 are located in the same country as the user terminal 220, the first router to the N-th router The extracted country information can be determined as the country where the user terminal 220 is located.

In addition, according to another embodiment of the present invention, since the DNS 240 connected to the user terminal 220 is located in the same country as the user terminal 220, the DNS 240 accesses the DNS 240 through the IP information of the DNS 240, 240 and obtain the country information of the obtained DNS 240 as the country where the user terminal 220 is located.

Finally, the country information extraction application 221 transmits the country information of the user terminal 220 determined above to the service server 200. The service server 200 collects information on a country where the corresponding user terminal 220 is located from each user terminal 220, and can use the collected information as advertisement or marketing information or apply the service policy to each country.

Country information extraction Application  function

FIG. 3 is a block diagram illustrating a detailed structure of functions performed by the country information extraction application according to an embodiment of the present invention, which can be installed and operated in the user terminal 220. 3, functions performed by the country information extraction application 221 according to the embodiment of the present invention include a network information request unit 310, a network information receiving unit 320, a country information transmitting unit 330, An inquiry unit 340, a country determination unit 350, and the like.

First, the network information request unit 310 transmits predetermined packet data to the service server 200, for example, by executing an instruction using ICMP. In accordance with the transmission, the network information receiving unit 320 receives IP information of at least one router located on the network information, that is, the path communicating with the service server 200 through the communication network 210. At this time, as described above, the TTL value can be set in the network information request unit 310, and the number of router IP information received by the network information receiving unit 320 can be changed according to the set TTL value.

The location information inquiry unit 340 extracts the country information corresponding to the IP information of the router by referring to the router location information database 250 with the IP information of the received router.

At this time, the corresponding router receiving the IP information according to the TTL setting is located in the same country as the user terminal 220. Therefore, the country determining unit 350 determines the country where the user terminal 220 is located based on the extracted country information of the router. Meanwhile, according to the embodiment of the present invention, the country determining unit 350 can determine the country of the user terminal 220 through various methods as described above.

For example, when the country information acquired from the plurality of routers 230 matches the set TTL, the country information of the user terminal 220 can be determined as the matching information. Also, when the country information acquired from the plurality of routers 230 does not match and there are more than two countries, a plurality of country information may be determined as the country of the corresponding user terminal 220. [

Meanwhile, according to another embodiment of the present invention, when the country information obtained from a plurality of routers is different, the reliability of the country decision can be increased by increasing or decreasing the number of target routers to be measured. That is, the country determining unit 250 may request the network information requesting unit 310 to increase or decrease the TTL value and retransmit the command using the ICMP.

When the country where the user terminal 220 is located is finally determined in the country determining unit 350, the country information transmitting unit 330 transmits the determined country information to the service server 200 through the communication network 210 do.

Meanwhile, according to another embodiment of the present invention, the location information inquiry unit 340 can acquire the country information of the DNS 240 through the IP information of the DNS 240 to which the user terminal 220 accesses. Accordingly, the country determining unit 350 determines the country information of the DNS 240 as the country of the user terminal 220 and transmits the determined country information to the service server 200 through the country information transmitting unit 330 Lt; / RTI >

Hereinafter, a procedure for extracting and transmitting country information by the country information extraction application will be described in detail with reference to FIGS. 4 to 6. FIG.

Country Information Extraction Procedure
