TR TR TR TR DESCRIPTION System That Enables the SIM Card to Receive Signal from a Specific Location TECHNICAL FIELD The invention is related to the system that enables the SIM card to be used in a specific location by receiving service from a single base station. The invention is particularly related to the system that prevents possible base station service disruption by matching the LMSl information of the SLM card with the Cell lD information of a base station, ensuring that the SLM card receives service from only one base station, thus ensuring that the SLM card can be used in a specific location. BACKGROUND ART Today, all corporate/individual customers in the telecommunication network structure can receive service from base stations in Turkey. However, when using an SLM card that has been sold on a Location basis with a high speed commitment, or a modem that works with an SLM card, in a location other than the intended address, base station saturation may occur and this may lead to connection problems. This situation affects all individual/corporate customers who receive signals from base stations other than the planned base station. A Turkish patent application titled "Method of Temporarily Limiting Connection Requests to the Mobile Network of Deactivated SLM Cards Embedded in Devices" has been found. The application in question has been found to limit the connection requests to the mobile network of SLM cards that are permanently/temporarily deactivated or unreachable over time, used in M2M devices, with the application installed on the SLM cards during the production phase. However, in the mentioned application, there is no sign of a system that allows the SLM card to be used in a specific location by receiving service from a single base station. As a result of the research in the literature, a Turkish patent application with the application number "2017/21020" was found. The application in question is related to a system that allows contactless updating of the lMSl (International Mobile Subscriber Identity) information on the SLM (Subscriber Identity Module) card provided by mobile operators to their customers. The system subject to the invention; It consists of SLM card, card reader, SLM card management unit and database components. However, in the application mentioned, there is no indication of a system that allows the SLM card to be used in a specific location by receiving service from a single base station. 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 aims to eliminate the above-mentioned disadvantages and bring new advantages to the relevant technical field. The main purpose of the invention is to ensure that the SLM card receives a signal only from a certain location. In order to realize all the purposes mentioned above and that will emerge from the detailed explanation below, the present invention is a system that allows the SLM card to be used in a specific location by receiving a signal from a single base station, and its feature is; 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 said 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 base station within the service area. SGSN, which receives radio packets and mobile network connection requests through signals and carries them to the GGSlee in order to distribute outgoing and incoming data packets from the base station, radius system and SGSN, which perform the necessary signaling and verification from the step when the first connection request is sent through the user device to the lP assignment step. HLR, which is the database in which the location information and APN information is kept, in which the MSlSDNl is queried whether it has any restrictions by communicating with signals, is used to ensure that the user device receives a signal from only one base station, by means of the software contained in the HLR and the SLM card belonging to the relevant base station. Application that matches cell lD-lMSl, which matches the lMSl code and rejects the connection when a connection request other than the matched cell lD and lMSl is received, SASN, which reduces the internet speed in case it receives a command to reduce the internet speed from the radius system, by converting the private lPl of the private number assigned to the subscriber in the internet APNl to general lP. CGN, which assigns real IP and forwards the connection request to the internet router, includes a router that connects the user device to the internet via the mobile operator network through the connection request it receives from the 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 system that enables the SLM card, which is the subject of the invention, to receive a signal from a certain location.

CGN .Router DETAILED DESCRIPTION OF THE INVENTION In this detailed description, the system that enables the SlM card, which is the subject of the invention, to receive a signal from a certain location will only create a limiting effect for a better understanding of the subject. is explained with examples. The system that allows the SLM card to receive a signal from a certain location, user device (1), base station (2), SGSN (3), HLR (4), application that matches Cell LD-LMSl (5), GGSN (6), radius system (7). ), SASN (8), CGN (9), router (10). 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, 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 (6). 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. The application (5) that matches the Cell LD-LMSl is used to ensure that the user device (1) receives a signal from only one base station (2) by means of the software running within the HLR (4) and the cell LD and SLM card belonging to the relevant base station (2). It is an application that matches the lMSl code and rejects the connection when a connection request comes for a cell lD or lMSl that is different from the matched cell lD and lMSll. GGSN (Gateway GPRS Support Node) (6) is the equipment that gives the dynamic IP address to the user equipment in the internet APN. The Radius system (7) is the equipment that performs 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. SASN (Service Aware Serving Node) (8) is the equipment that implements the decision made, such as reducing the internet speed. CGN (Carrier Grade NAT) (9) is the equipment that assigns real IP by converting the private IP of MSlSDN to public IP in internet APN. Router (10) is the router device that extends the equipment connection from the mobile operator network to the internet. 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 (6) 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 (6) records the user's current SGSN (3) address and profile. GGSN (6) also undertakes authentication and upload functions. A GGSN 6 is an interface to external packet data networks for many SSGNs. SGSN (3) sends its packages to different networks via different GGSNs (6). 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. It has been created in order for the user device (1) to receive service only from the permitted high capacity base station (2) and to provide the customer with a high level of connection quality and speed. When the customer takes his SLM card modem and takes it to a different location, he will not be able to connect to the mobile operator network and thus will not be able to negatively affect the data speed of individual customers in the relevant region. Otherwise, both he and individual customers in the region will be affected by the network density. The system, which allows the SLM card to receive a signal from a certain location, captures all connections that want to connect to the mobile operator (preferably Türk Telekom) network. It takes the lMSl (International Mobile Subscriber Identity-SlM Card Serial Number) information of the captured connection and checks whether it is in the cell number (cell lD)-lMSl matching table. If the cell lD assigned to the connecting lMSl and the cell lD-lMSl match in the database are the same, the connection is allowed and the connection is continued. When a connection request is made to the mobile operator network from the User Equipment (1), the traffic is carried to the SGSN (3) via the base station (2) and the SGSN (3) transmits the connection to the HLR (4) and the application that matches the Cell lD-lMSl (5). ) thanks to SlM, it obtains the Cell lDl and lMSl information of the card and checks whether it exists in the cell lD-lMSl matching table in its database. For this, Cell 1D-lMSl matching must be done in the table where lMSls are kept in HLRl's own database (4). After defining the lMSl code in the table where lMSl-Cell lDls are kept, all connection requests sent from these lMSls are checked for cell lD matching and returned with an acceptance or rejection response for connections to the internet network. If the lMSl-Cell LD matching that makes the connection in the lMSl definition table is not correct, the connection is terminated by giving a rejection message. If the lMSl-Cell lD matching received is incompatible with the matching in the database, the connection is terminated by rejecting the connection. If the lMSl-Cell 1D pairing it receives is compatible with the matching in the database, the connection is given by the HLR (4) and forwards the connection to the GGSN (6). GGSN (6) assigns a dynamic IP to the incoming connection and obtains the network connection authority and approval for the connection from the radius system (7). The connection is then directed to the SASN (8) equipment and transmitted to the CGN (9) equipment via SASN (8). Static lP blocks are predefined in CGN (9) equipment. If the CGN (9) equipment covers the connection request received with the static IP address, it transmits the connection directly to the internet router (10) without taking any action. TR TR TR TR
