TR TR DESCRIPTION TECHNICAL FIELD The invention relates to a system that prevents the SLM card from being used in any device other than the device in which it is intended to be used. The invention is especially related to the lMSl-lMEl matching system, which matches the lMEl and lMSl code and thus prevents the SlM card from being used in any device other than the device for which it is intended to be used and for purposes other than its intended purpose. BACKGROUND ART Today, a mobile user can use his SLM card on any device he wants via the mobile operator infrastructure. In the current system, a line that is corporate and must work on a specific device can be used for purposes other than intended and individually by changing the device. As a result of the research in the literature, a Turkish patent application with application number "2018/05236" and the invention title "lMSl- MGB APN MATCHING SYSTEM" was found. The application in question is related to a matching system that eliminates the obligation to use MSlSDNs defined as MGB APN, by defining MGB APN in the lMSl code of the SLM card. However, in the application mentioned, there is no sign of the system that matches the lMEl and lMSl code and thus prevents the SlM card from being used for purposes other than the device on which it is intended to be used. As a result of the research in the literature, a Turkish patent application with application number "2018/06974" and the invention title "TAC-lMSl MATCHING SYSTEM AND METHOD" was found. The application in question enables the lMSl (lnternational Mobile Subscriber Identity) number of a SLM card that is desired to be used in a specific device and not wanted to be used in another device even if it is the same model, to be matched with the TAC (type approval code) code of the preferred device, thus ensuring that the SLM card's TAC It is about a system and method that prevents it from being used with any other device other than the device with which it is paired with its code. However, in the application mentioned, there is no sign of the system that matches the lMEl and lMSl code and thus prevents the SlM card from being used for purposes other than the device on which it is intended to be used. As a result, the problems mentioned above, which cannot be solved in the light of the current technique, necessitated an innovation in the relevant technical field. BRIEF DESCRIPTION OF THE INVENTION The present invention is related to the lMSl-lMEl matching system in order to eliminate the above-mentioned disadvantages and bring new advantages to the relevant technical field. The main purpose of the invention is to prevent the SLM card from being used in any other device other than the device for which it is intended to be used, by matching the lMEl and lMSl code. In order to realize all the purposes mentioned above and that will emerge from the detailed explanation below, the present invention is the lMSl-lMEl matching system, which prevents the SLM card from being used in any other device other than the device for which it is intended to be used and for purposes other than its intended purpose. The user device that sends a signal to the base station and receives the signal from the base station through the SLM card in it to connect to the internet network, the base station that sends a signal through the user device to enable it to connect to the internet network, the GGSN that gives the dynamic IP address to the user device in the internet APN, the device that goes to the base station within the service area. and SGSN, which receives radio packets and mobile network connection requests through signals and carries them to the GGSlee in order to distribute the data packets coming from the base station, performs the necessary signaling and verification from the step when the first connection request is sent through the user device to the lP assignment step, and incoming connection to approve or reject the connection. In its requests, the radius system obtains the authorization information of connection requests such as internet APN, MGB APN and static LP via GGSN by creating a query for MSlSDN from the radius database. HLR, which is the database where the location information and APN information is kept and where the location information and APN information is kept, is the lMSl-lMEl, which matches the lMEl number of the user device with the lMSl code of the SlM card in order to prevent the SlM card from being used on another device other than the device it is intended to be used with, through the software in the radius database and run within it. The matching application is SASN, which reduces the internet speed and performs the charging process for the internet APN in the mobile operator network in case it receives a command to reduce the internet speed from the radius system. CGN, which converts the private lP of the private number assigned to the subscriber in the internet APN to the public LP, assigns the real LP and forwards the connection request to the internet router. It includes a router that connects the user device to the internet via the mobile operator network through the connection request it receives from CGN. In order to best understand the structure of the present invention and its advantages with additional elements, it should be evaluated with the figures explained below. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a representative illustration of the lMSl-lMEl coupling system that is the subject of the invention. Drawings do not necessarily have to be scaled and details that are not necessary to understand the present invention may be omitted. Furthermore, elements that are at least substantially identical or have at least substantially identical functions are designated by the same number.

Router DETAILED DESCRIPTION OF THE INVENTION In this detailed description, the lMSl-lMEl pairing system, which is the subject of the invention, is only for a better understanding of the subject, without any limitations. It is explained with examples that will not create any impact. lMSl-lMEl pairing system, user device (1), base station (2), SGSN (3), HLR (4), GGSN (5), radius system (6), radius database (7), lMSl-lMEl pairing application (8), SASN (9), CGN (10), router (11). The user device (1) is the device that sends a signal to the base station (2) and receives a signal from the base station (2) through the SLM card inside it, in order to connect to the internet network. User devices (1) are electronic devices such as mobile phones and tablets. The base station (2) is the equipment that sends signals through the user device (1) to enable it to connect to the internet network. SGSN (Serving GPRS Support Node) (3) is the device that allows radio packets to be received and carried up to GGSlee (5). HLR (Home Location Register) (4) is a special number assigned to the subscriber by the operator for the identification and verification of the subscriber in MSlSDN (GSM or UMTS mobile networks - it may also be the SLM card phone number) where any person is queried, location information and It is the equipment where APN information is kept. GGSN (Gateway GPRS Support Node) (5) is the equipment that gives the dynamic IP address to the user equipment in the internet APN. The Radius system (6) carries out the required 2 (preferably Authentication Accounting) signaling processes, from the step when the first connection request is sent via the user device (1) to the step where the IP is received, and for incoming connection requests to approve or reject the connection, the radius database ( 7) It is the equipment that obtains the authorization information of connection requests such as internet APN, MGB APN and static lP by creating a query for MSlSDN. Radius database (7) is the database where lP addresses are kept for services such as MGB APN, static lP. lMSl-lMEl matching application (8) is the application that matches the lMEl number of the user device (1) with the lMSl code of the SlM card, in order to prevent the SlM card from being used on another device other than the device on which it is intended to be used, by means of the software running in the radius database (7). SASN (Service Aware Serving Node) (9) is the equipment that implements the decision such as reducing the internet speed and performs charging operations for the internet and WAP APN in the mobile operator network. CGN (Carrier Grade NAT) (10) is the equipment that assigns real IP by converting the private IP of MSlSDN to public IP in internet APN. Router (11) is the router device that extends the equipment connection from the mobile operator network to the internet. lMSl (International Mobile Subscriber Identity) is the number embedded on the SLM card chip and contains the international subscriber and network number in portable telephone technology. This number identifies the individual operator network, which is the network on which the SLM card operates, and allows the SLM card to communicate with the network provider. SlM (Subscriber Identity Module) card is an integrated circuit that allows securely storing the lMSl number and the relevant key. lMEl (International Mobile Equipment Identity Code) number is defined as an identification number that must be present on all mobile phones (devices). MSlSDN is a special number assigned to the subscriber by the operator for identification and verification of the subscriber in GSM or UMTS mobile networks. When the user turns on his phone and registers to the system using the lMSl number contained in the SLM card that identifies the subscriber, the system assigns the MSlSDN number determined in the operator database to this connection. SGSN (3) is responsible for the distribution of data packets to and from the mobile station within the service area. The tasks of SGSN (3) are functions such as packet routing and transfer, mobility management (connecting, detaching and location management), logical link management, authentication and upload functions. GPRS (General Packet Radio Services) is a new carrier service for GSM (Global System for Mobile Communications) that facilitates and strengthens wireless access to packet data networks. It uses the packet radio principle to transfer user data packets between external packet data networks and mobile stations. Packets are routed directly from GPRS mobile stations to packet-switched networks. Since it works with the packet transmission method, data transfer is faster and response times are much less. While the normal transfer rate in the GSM band is 14.4 Kbps (Kilobits Per Second), this figure can be 115 Kbps in GPRS. GGSN (5) acts as an intermediary between external packet data networks and the GPRS rib. It converts the GPRS packets coming from the SGSN (3) into the appropriate packet data protocol (PDP=Packet Data Protocol) (such as IP or X.25) and sends them to the packet data network. In the opposite direction, the PDP addresses of the incoming data packets are converted to the GSM address of the target user. Readdressed packets are sent to the responsible SGSN (3). For this purpose, GGSN (5) records the user's current SGSN (3) address and profile. GGSN (5) also undertakes authentication and upload functions. A GGSN (5) is an interface to external packet data networks for many SSGNs. SGSN (3) sends its packages to different networks via different GGSNs (5). HLR (4) is the database of all mobile numbers registered in a GSM network. HLR (4) keeps a record of subscribers' SlM card IDs (lMSl) and mobile phone numbers (MSlSDN). APN (Access Point Name) is the address that provides routing information within the GPRS network. The lMSl-lMEl pairing system will be used in mobile devices that use the telecommunication infrastructure by inserting an SlM card. With the improvements made, the serial number (lMEl: lnternational Mobile Equipment ldentity, "serial number of the device") of a SLM card that is intended to be used on a specific device and not to be used on any other device, even if it is the same model, is matched with the lMEll (lnternational Mobile Equipment ldentity, International mobile equipment identity) of the device. The relevant line cannot be used on any other device. In other words, if the SLM card is inserted into another device, it will not be able to connect to the Türk Telekom mobile network and will not be able to use it in this way. The lMSl-lMEl pairing system captures all connections that want to connect to the mobile operator (preferably Türk Telekom) network. By taking the lMSl and lMEl information of the captured connection, it is checked whether there is a correct match in the lMSl-lMEl matching table in the radius database (7). If the lMSl-lMEl pairing from the device making the connection request is correct, the connection will be allowed. If it is not correct, a rejection response will be returned to the connection. When the user device (1) creates a connection request to the mobile operator network, the traffic is transported to the SGSN (3) via the base station (2) and the SGSN (3) is transferred to the HLR (4) by the restriction of this line, APN (Access point network). It receives information such as information and transmits the data to the relevant internet GGSNline (5). For each connection request to the Internet, GGSN (5) receives connection authorization and approval from the radius system (6). For this connection request, the radius system (6) provides the query from its own database, the radius database (7). The lMSl-lMEl matching application in the Radius database (7) receives the lMEl and lMSl information coming with the connection during the connection query through the software run in the application (8). Checking whether this incoming information is the same as the lMEl-lMSl matching in the table is done from the table (7) in the internet radius database. To do this, it is sufficient to define the numbers in the radius database (7) with which the user devices (1) are to be matched, in the table where the lMEl-lMSl matching is kept. If there is no lMEl-lMSl information making the connection in the lMEl-lMSl definition table, the connection is rejected. If the lMEl-lMSl information that makes the connection in the lMEl-lMSl definition table is present in the definition table, the connection is directed to the SASN (9) equipment and transmitted to the CGN (10) equipment via SASN (9). After the CGN (10) equipment, the traffic is transmitted to the internet router (11) and access to the real internet is provided. TR TR

The radius system (6), which receives the authorization information of connection requests such as over GGSN (5), the mentioned radius database (7), in which IP addresses for MGB APN and static IP services are kept, communicates with the radius system (6) and is queried whether MSlSDN has any restrictions. HLR (4), which is the database in which the location information and APN information is kept, is used to prevent the SLM card from being used on another device other than the device that is intended to be used, by means of the software in the radius database (7) and the LMEl number of the user device (1) and the SLM card. lMSl-lMEl matching application (8), which matches the lMSl code, SASN (9), which reduces the internet speed in case it receives a command to reduce the internet speed from the radius system (6) and performs the charging process for the internet APN in the mobile operator network, 0, the special number assigned to the subscriber in the internet APN. It contains the CGN (10), which converts the lPl into a general lP, assigns the real lP and transmits the connection request to the internet router (11), and the router (11), which connects the user device (1) to the internet via the mobile operator network, through the connection request received from that CGN (10).
