Abstract

PURPOSE: A method for classifying same ESN(Electronic Serial Number) and UIM-ID(User Identity Module-IDentifier) mobile communication network is provided to classify whether a hardware ID is the ESN or the UIM-ID without passing an authentication operation about a terminal. CONSTITUTION: An HLR(Home Location Register) performs an error check about parameters included in a received mobile communication service process request message(S12). If an error is not detected, the HLR judges whether a classifier parameter exists in the corresponding mobile communication service process request message(S14). If the classifier parameter does not exist in the corresponding mobile communication service process request message, the HLR judges a hardware ID included in the mobile communication service process request message as an ESN and confirms a corresponding MS(Mobile Station) as a unified terminal(S16). If the classifier parameter exists in the corresponding mobile communication service process request message, the HLR judges the hardware ID as a UIM-ID and confirms the corresponding MS as a terminal installing a UIM(S18). The HLR judges whether the hardware ID discriminated as the ESN or the UIM-ID is not duplicated(S20). If the hardware ID is not duplicated, the HLR judges whether the hardware ID and the MIN are paired(S24). If the hardware ID and the MIN are paired, the HLR performs an operation requested by a mobile subscriber using the MS(S28).

Description

Method of same ESN and UIM-ID distinction in mobile communication network

The present invention relates to a method for distinguishing the same ESN and UIM-ID in a mobile communication network, and in particular, a terminal capable of mounting a user identity module (hereinafter referred to as a UIM) and a terminal which cannot be equipped with a UIM coexist in the same mobile communication network. The user identity module identifier (hereinafter referred to as UIM-ID) transmitted by a terminal capable of mounting the UIM and the terminal serial number (Electronic Serial Number; If the ESN has the same value, the same ESN in the mobile communication network prevents collisions between two values that play the same role in the mobile communication system and separates them so as to accurately perform an operation requested by each terminal. And how to distinguish between UIM-IDs.

Conventionally, a terminal used in a mobile communication service includes all the standard information, hardware operation related information, call processing information, user's personal information, etc. inside the hardware and is used when the user uses the mobile communication service. The phone number of the other person entered by the user with the mobile identification number (hereinafter referred to as MIN) to identify the user, various parameter information required for call processing, roaming list for roaming, and values related to authentication. You can store all your numbers, messages, and personal schedule management information.

As described above, the standard information about the terminal includes a terminal serial number (ESN), terminal version information, power consumption specification, and the like, and information related to hardware operation includes information used for wireless connection such as CDMA channel information to be used in the terminal; Information on the size of various sounds used in the terminal is included.

In the conventional integrated terminal as described above, since all information is stored in one hardware, personal information or security-related information is easily exposed to those who are familiar with the terminal, those who are in charge of, or experienced, such as upgrading or repairing the terminal. There is a problem that can be changed. If the terminal is broken or needs to be upgraded, the user cannot use the mobile communication service until the terminal is repaired, and if the terminal is no longer available, the user must purchase a new terminal. When a provider provides a new function, if the user's terminal cannot provide it through a function upgrade, the user cannot use this function until a new terminal is purchased. If the user cannot use the current terminal when roaming to another region (roaming is impossible), the user stops using the current terminal and rents or purchases the terminal available in the region in advance. There is an uncomfortable problem of using a mobile communication service.

As described above, the conventional terminal has a problem in that the user can be provided with various risks such as burdens and inconveniences on the use of the mobile communication service and his personal information may be exposed.

Accordingly, the GSM (Global System for Mobile Communications) mobile communication service used in Europe where free transboundary movement and transnational mobile communication service companies exist has the above-mentioned problems. SIM is manufactured in the form of a card or chip and should not be disclosed to others, various personal information valid only for users, and various call processing information that can be changed when using a mobile communication service. In addition, the mobile terminal includes unique supplementary service processing information provided only by the mobile communication service company to which the user is subscribed.

The SIM as described above is mounted on a terminal capable of mounting the SIM to enable a user to use a mobile communication service. A terminal equipped with a SIM stores only hardware related information or a radio resource access method used by the terminal. Since a SIM can be easily attached and detached from the terminal, the terminal may be damaged or may be used. If a user moves to an area where there is no radio frequency band, for example, the radio frequency band is wrong, the user can continue to use the mobile communication service without any inconvenience by attaching it to another terminal that can be detached from the terminal. In addition, when a new additional service is provided, upgrading only the software of the SIM or a parameter to be used therein enables the corresponding service to be used without using a method of replacing the terminal.

Meanwhile, in North America using a mobile communication service using a code division multiple access (CDMA) scheme, the above-mentioned problem is solved by using a UIM. Like the SIM, the UIM includes user's personal information, information required for call processing, and mobile communication. Information on the service providing method is stored.

As described above, the UIM is attached to a terminal capable of accommodating the UIM so that the user can be provided with a mobile communication service. Since the UIM is portable and easy to move, the information stored therein must be safely protected. . Accordingly, the UIM does not allow any other access except for access to authorized users or designated mobile communication service operations, protected by passwords, access right restrictions, etc., for the safety of information.

On the other hand, since the UIM is a medium for storing information of a user using a mobile communication service and identifying each user, there is an identifier for distinguishing each UIM. The UIM-ID is a system of an existing mobile communication service. It is used to identify the terminal being used by the user together with the MIN in the same manner as the serial number (ESN) of the integrated terminal, which has been used so far to accommodate the user identification module terminal without changing. Therefore, the UIM-ID can accommodate up to 56 bits in the same way as the ESN, but the length to be used is proposed to be composed of a 32-bit serial number such as the currently used ESN.

As described above, in the mobile communication network in which the existing integrated terminal and the terminal using the UIM coexist, it is necessary to distinguish between two different parameters that can be transmitted in the same field. This is because the UIM-ID may be transmitted to the mobile communication network element by replacing the existing ESN value. Since the UIM-ID has the same length as the ESN, the UIM-ID may have the same value as the ESN used in other terminals.

Meanwhile, an authentication process is performed to distinguish between a terminal using an existing ESN and a terminal using a UIM, or to monitor whether the UIM is a legitimate move if the UIM is moved to another terminal for some reason. Since the procedure may reduce the quality of mobile communication service, it may be selectively provided by the mobile communication service provider or the network operator such as authenticating only at a specific service operation such as location registration or by user request. It cannot always be used to distinguish between the same ESN and UIM-ID. Therefore, if the ESN and UIM-ID values of existing terminals used by different users are the same in the service area provided by the mobile communication network element for which no authentication procedure occurs for any reason, the current mobile network element function or service operation procedure is performed. The terminal cannot determine whether the terminal uses a different number after being copied through an illegal method, and whether the two devices are legal and the types of terminals used are different. In addition, if the integrated terminal receives a service provided based on the ESN, there is a problem in which one of the two terminals needs to be provided using only the ESN and the UIM-ID.

The present invention has been made to solve the above-mentioned problem, and distinguishes whether the hardware identifier included in the message is ESN or UIM-ID based on the identifier inserted in the mobile communication service processing request message received from the terminal, By identifying whether the hardware identifier included in the mobile communication service processing request message received from the terminal is ESN or UIM-ID based on the subscriber information registered in the HLR, even if the terminal does not undergo authentication, the hardware identifier The purpose of the present invention is to provide a method for distinguishing between the same ESN and UIN-ID in a mobile communication network capable of distinguishing between ESN and UIM-ID.

Hereinafter, with reference to the accompanying drawings will be described in detail the same ESN and UIM-ID identification method in a mobile communication network according to an embodiment of the present invention.

1 is a road showing a mobile communication network configuration to which the same ESN and UIM-ID classification method is applied according to the present invention. The mobile communication network according to the present invention includes a mobile station (MS) 10 and a mobile switching center (MSC) 20. ), A VLR (Visitor Location Register) 30, and a HLR (Home Location Register) 40.

In such a configuration, the MS 10 moves to the MSC 20 at the subscriber's request, including the MIN, a hardware identifier (hereinafter referred to as a H / W-ID), an indicator, and the like. Sends a communication service processing request message to request mobile communication service processing such as location registration and call origination.

The MSC 20 performs a function of connecting a general wired telephone network and a mobile communication network, connects a call between a mobile subscriber and a wired telephone subscriber and a mobile subscriber, and switches a call channel and detects a mobile position when a cell is changed during a call. And performing a location registration function or the like, and transmitting the mobile communication service processing request message including the MIN, H / W-ID, identifier, etc. received from the MS 10 according to the mobile communication service processing request of the MS 10. Transfer to 30.

The VLR 30 temporarily registers subscriber information of the MS 10 according to the location registration procedure of the MS 10 when the MS 10 registered with the other MSC 20 has moved to its own jurisdiction. The MS 10 stores the database based on the MIN, H / W-ID, identifier, etc. transmitted from the MSC 20 according to the mobile communication service processing request of the MS 10 received from the MSC 20. The mobile communication service processing request message is transmitted to the registered HLR 40 to request the corresponding mobile communication service processing, and the mobile communication service processing result received from the HLR 40 is transmitted to the MS 10 through the MSC 20. send.

The HLR 40 is a database that stores all the permanent information of the MS 10 required to connect an incoming call to the MS 10 or provide other mobile communication services. The HLR 40 is received from the VLR 30. The mobile communication service is processed according to the mobile communication service processing request message, and the processing result is transmitted to the VLR 30.

First, a description will be given of a method for distinguishing the same ESN and UIM-ID in a mobile communication network according to an embodiment of the present invention.

2 is a flowchart illustrating a method for distinguishing between the same ESN and UIM-ID in a mobile communication network according to an embodiment of the present invention.

First, when a mobile subscriber wants to be provided with mobile communication services such as location registration and call origination using a terminal equipped with a UIM, the mobile subscriber uses the MS 10 and the HLR 40 through the MSC 20 and the VLR 30. Transmits a mobile communication service processing request message including a MIN, an H / W-ID, an indicator, and the like to request mobile communication service processing such as location registration and call origination (S10).

When the mobile communication service processing request message is transmitted to the HLR 40 in step S, the identifier parameter for distinguishing whether the H / W-ID included in the message is an ESN or a UIM-ID is inserted. For example, if the H / W-ID included in the message is an ESN, the separator parameter is not inserted in the message. If the H / W-ID included in the message is a UIM-ID, the separator parameter is inserted in the message. send.

As described above, the HLR 40 that has received the mobile communication service processing request message from the MS 10 through the MSC 20 and the VLR 30 may determine parameters included in the received mobile communication service processing request message. If an error is not detected by performing an error check, it is determined whether a delimiter parameter exists in the corresponding message (S12, S14).

If the discriminator parameter does not exist in the mobile communication service processing request message as a result of the determination of step S14, the MS 10 determines the H / W-ID included in the received mobile communication service processing request message as an ESN. Confirm that the integrated terminal (S16).

On the other hand, if there is a separator parameter in the mobile communication service processing request message as a result of the determination in step S14, the MS (H / W-ID included in the received mobile communication service processing request message is determined as the UIM-ID and the corresponding MS ( 10) confirms that the terminal is equipped with a UIM (S18).

Thereafter, it is determined whether the H / W-ID determined as the ESN or the UIM-ID is not duplicated through the processes S14 to S18 (S20).

As a result of the determination of step S20, if the H / W-ID is duplicated, an error is processed. If the H / W-ID is not duplicated, it is determined whether the H / W-ID and the MIN are paired (S22). , S24).

In the process S24, the determination of whether the H / W-ID and the MIN are paired is performed by referring to a database in which subscriber information of each subscriber is stored.

If the H / W-ID and MIN are not in pairs, an error process is performed. If the H / W-ID and MIN are in pairs, the MS 10 moves. Perform the operation requested by the subscriber (S26, S28).

As described above, the method for requesting the mobile communication service processing by inserting a delimiter parameter for distinguishing whether the H / W-ID is an ESN or a UIM-ID into the mobile communication service processing request message is performed by the terminal equipped with the UIM. Even when the ESN is used without using the UIM-ID as the W-ID, it is possible to distinguish whether the H / W-ID represents the ESN or the UIM-ID.

In addition, the H / W-ID is used as an ESN or as a UIM-ID without the help of the HLR 40, which stores permanent call-related data for a user in a mobile network element other than the HLR 40. Can be determined.

Hereinafter, a description will be given of a method for distinguishing between the same ESN and UIM-ID in a mobile communication network according to another embodiment of the present invention.

First, in order to implement the same ESN and UIM-ID classification method in a mobile communication network according to another embodiment of the present invention, when the subscriber information is registered in the HLR 40, the MS 10 of the user can mount the UIM. It should be stored whether the UIM acceptance field (field) to distinguish whether the integrated terminal, Figure 3 is an illustration showing a database configuration of the HLR 40 according to another embodiment of the present invention.

As shown in FIG. 3, the database of the HLR 40 according to another embodiment of the present invention includes an operation data unit a in which data necessary for operation is stored, and information on each mobile subscriber. Subscriber data portion (b) and other data portion (c).

The above-described subscriber data unit (b) stores information about each mobile subscriber, and the information on the mobile subscriber includes MIN, H / W-ID, UIM acceptance, and the like.

As described above, when storing the information on each mobile subscriber in the subscriber data unit (b), it also stores information about whether to accept the UIM, which stores information about whether to accept the UIM in the subscriber data unit (b) As a method, as shown in FIG. 4, one of the values (for example, the eighth bit) of the value of the 'Authentication Capabilities' parameter indicating the authentication capability among the various parameters indicating the terminal attribute is selected. When storing information about each mobile subscriber using the value to determine whether the UIM can be equipped with the UIM can be installed, set the value to a value that can know whether to accept the UIM, or In each subscriber information, a UIM acceptance field may be separately stored to indicate whether the UIM is accepted.

5 is a flowchart illustrating a method for distinguishing between the same ESN and UIM-ID in a mobile communication network according to another embodiment of the present invention.

In order to receive mobile communication services such as location registration and call origination, the mobile subscriber includes the MIN, H / W-ID, etc. to the HLR 40 through the MSC 20 and the VLR 30 using the MS 10. The mobile communication service processing request message is transmitted to request mobile communication service processing such as location registration and call origination (S30).

As described above, the HLR 40 that has received the mobile communication service processing request message from the MS 10 through the MSC 20 and the VLR 30 may determine parameters included in the received mobile communication service processing request message. If an error is not detected by performing an error check, the subscriber information is retrieved using the MIN included in the mobile communication service processing request message (S32, S34).

Thereafter, it is determined whether the MS 10 that has transmitted the mobile communication service processing request message is a terminal capable of receiving a UIM based on the information contained in the subscriber information retrieved in step S34 (S36).

As a result of the determination in step S36, if the MS 10 is not a terminal capable of accepting the UIM, the MS 10 determines the H / W-ID included in the received mobile communication service processing request message as an ESN. Confirm that the integrated terminal (S38).

On the other hand, when the MS 10 determines that the UIM is a terminal capable of accepting the UIM, the MS (H / W-ID included in the received mobile communication service processing request message is determined as the UIM-ID and the corresponding MS ( 10) confirms that the terminal is equipped with a UIM (S40).

Thereafter, it is determined whether the H / W-ID determined as the ESN or the UIM-ID is not duplicated through the processes S36 to S40 (S42).

As a result of the determination in step S42, if the H / W-ID is duplicated, error processing is performed. If the H / W-ID is not duplicated, it is determined whether the H / W-ID is paired with the MIN (S44). , S46).

As a result of the determination in step S46, if the H / W-ID and the MIN are not paired, an error is processed. If the H / W-ID and the MIN are paired, the MS 10 moves to the MS 10. Perform the operation requested by the subscriber (S48, S50).

As described above, when registering the subscriber information to the HLR 40, by storing the UIM acceptance field to distinguish whether the MS 10 of the user is equipped with a UIM terminal or an integrated terminal, HLR (40) When there is a request for processing a mobile communication service such as location registration or call origination, the user can determine whether the H / W-ID is an ESN or UIM-ID only by searching for information without using a method such as adding a parameter.

The same ESN and UIM-ID classification method in the mobile communication network of the present invention is not limited to the above-described embodiments and can be modified in various ways within the scope of the technical idea of the present invention.

As described above, according to the same ESN and UIM-ID classification method in the mobile communication network according to the present invention, the hardware identifier included in the message is based on the identifier inserted in the mobile communication service processing request message received from the terminal. Network load or network load by distinguishing whether it is ESN or UIM-ID or whether the hardware identifier included in the mobile communication service processing request message received from the terminal is ESN or UIM-ID based on subscriber information registered in the HLR. Due to the deterioration of service quality, it is possible to distinguish whether the hardware identifier is ESN or UIM-ID when the terminal performs the requested operation without going through the authentication operation.
