As shown in FIG. 2 (a), there are a smart card H / W such as a RAM, a ROM and a CPU, a smart card operating system for controlling and processing the smart card H / W, There is a smart card file system in which the data of the smart card is stored. Accordingly, when the terminal such as a smart phone requests the subscriber identification information, the input / output device existing on the smart card H / W receives the subscriber identification information, and then, in the smart card operating system, And a card information management module, accesses the corresponding information in the smart card file system using the smart card API, and provides the subscriber identification information requested by the terminal.

2 (b) illustrates a file structure in a USIM, which is one of representative smart cards. As shown in FIG. 2 (b), there is one master file (MF) in a conventional USIM file structure including one subscriber identification information, and a dedicated file , DF), and there exists an application dedicated file (ADF) in which subscriber identification information for real mobile communication network interworking exists. In particular, as shown in FIG. 2, an ADF usim file for managing USIM file information is linked to a directory element file (EF DIR ) accessed from a master file (MF).

In the ADF usim file, there are elementary files (EFs) necessary for connection to a mobile communication network. For example, an integrated circuit card ID number corresponding to a USIM serial number, keys for EF MSISDN, the network connection to the ICCID) EF ICCID, the information corresponding to the EF IMSI, phone number for user identification on the network International Mobile Subscriber Identity (IMSI) Mobile Station International ISDN number (MSISDN) for the A series of subscriber identification information required for subscriber authentication of the terminal 110, including EF Kc for Kc for managing information, and the like can be stored and managed.

3 (a) shows a flowchart of a terminal booting process in the terminal 110, such as a smartphone using a general user ID (USIM) having one subscriber identification information.

First, when power is applied to the terminal 110, the terminal 110 confirms the existence of the USIM and the state of the USIM through the ATR / PPS processing. If it is confirmed that the USIM exists in the terminal 110 and operates normally, the master file MF is selected in the USIM.

When a selection is made for the master file MF, the dedicated file DF and the element file EF existing under the master file MF are checked, and the presence or absence of the double directory element file EF DIR And information about it.

Then, when the directory component file (EF DIR) is present, it is accessible to the directory element file (EF DIR) and the link (Link) an idealistic application-specific file (ADF USIM) are interlocked. Then, files such as EF IMSI , EF ICCID , EF MSISDN , and EF Kc existing in the wicket application dedicated file (ADF USIM ) are read.

Through this series of processes, the terminal 110 can obtain subscriber identification information from the USIM and further can perform a subscriber authentication procedure for the communication network 130 using the subscriber identification information do.

3 (b), a flowchart of a terminal booting process in the terminal 110, such as a smart phone using a general user ID (USIM) having one subscriber identification information, is shown in FIG. 3 (a) .

3 (a) and 3 (b), the user removes the existing USIM from the terminal 110, mounts a USIM having new subscriber identification information, The subscriber authentication of the terminal 110 can be renewed by using the new subscriber identification information through a series of processes of FIGs. 3A and 3B by applying power to the terminal 110 and rebooting it .

Meanwhile, FIG. 4 illustrates a flowchart of a method for changing subscriber identification information in a terminal using a smart card including a plurality of subscriber identification information according to an embodiment of the present invention. 4, a method for changing subscriber identification information in a terminal using a smart card according to an exemplary embodiment of the present invention includes a user providing step S410, a smart card setting step S420, S430). In addition, the terminal 110 may further include a subscriber authentication step (not shown) for performing a subscriber authentication procedure for the first communication network 130 using the main subscriber identity information transmitted from the smart card .

In this regard, FIG. 5 illustrates a structure of a file system of a smart card including a plurality of subscriber identification information according to an embodiment of the present invention. As shown in FIG. 5, in a smart card according to an exemplary embodiment of the present invention, unlike a general smart card (USIM) having only one subscriber identification information, a plurality of A deactivated Deactive_MF1, Deactive_MF2, etc., as well as a master file, that is, an active default master file MF. At this time, each of the master files may include a lower file structure. The master file and the lower file structure for each master file may include a master file of a smart card including only one subscriber identification information, It is possible to maintain compatibility by having the same file structure as that of the lower file structure for each master file.

Accordingly, in the subscriber authentication step (not shown), as shown in FIG. 5, only the activated MF can be recognized as a default, and using the subscriber identification information stored in the MF sub- It is possible to perform the subscriber authentication procedure for the first communication network.

In step S410, the subscriber station 110 receives a part or all of the plurality of subscriber identification information from the smart card, displays each subscriber identification information in an active or inactive state, and provides the subscriber identification information to the user. 6, the terminal 110 sequentially activates a part or all of the plurality of master files by using an applet driven in the smart card, After receiving the stored subscriber identification information, the subscriber identification information is provided to the user. Subsequently, when the user selects one of the plurality of subscriber identification information, subscriber authentication for the first communication network can be updated using the selected subscriber identification information.

In this case, a series of processes of providing a plurality of subscriber identification information to the user and inputting subscriber identification information of the user may be implemented in the form of an app running on the terminal 110, such as a smart phone. Accordingly, the user can easily change the subscriber identification information by selecting the subscriber identification information using the application while the terminal 110 is operating.

In addition, the app running on the terminal 110 may include not only a general application program running on a smart phone, but also a SIM Toolkit program that can be used to manage information on USIM.

In addition, the terminal 110 does not necessarily have to use an app, and various methods of providing a part or all of the plurality of subscriber identification information to the user may be adopted.

Next, in the smart card setting step S420, the subscriber station 110 transmits a predetermined signal to the smart card to set the first subscriber identification information selected by the user as the main subscriber identification information, The subscriber identification information may be deactivated. 6, if the subscriber identification information selected by the user corresponds to Deactive_MF1 of FIG. 6, the terminal 110 transmits a predetermined signal The currently active MF is deactivated, and the deactivated Deactive_MF1 is activated, so that the subscriber identification information recognizable by the terminal 110 is changed.

Subsequently, in the subscriber authentication update step (S430), the subscriber terminal 110 updates subscriber authentication for the first communication network using the first subscriber identification information. At this time, in the subscriber authentication update step (S430), authentication through the active primary subscriber identity information is canceled without rebooting the terminal 110, and using the first subscriber identity information, The subscriber authentication process for the subscriber station 130 is performed.

Further, in an operating system driven by the subscriber station 110, a smart card including only a plurality of subscriber identification information is processed in the same process as the process of processing subscriber identification information with respect to a smart card including only one subscriber identification information, (E.g., an Android operating system) operating at the terminal, even if a smart card including a plurality of subscriber identification information is used by processing the main subscriber identification information with respect to the card, The processing procedure is not modified, thereby ensuring compatibility and stability of the terminal.

In addition, FIG. 7 illustrates a subscriber identification information change process using a smart card using another file structure as an embodiment of the present invention.

7, in addition to the ADF usim , which is an application specific file (ADF) that operates as a default in a subfolder structure of one master file (MF), a plurality of applications such as ADF usim1 and ADF usim2 Dedicated files (ADFs) can exist. At this time, the element files EF included in the conventional ADF usim exist in the same structure in the ADF usim1 , ADF usim2, and the like.

As shown in FIG. 7, the smart card has a wormhole application dedicated file (ADF usim ), and the wormhaft application specific file (ADF usim ) is linked to the directory element file (EF DIR ) It is possible to maintain compatibility with a conventional USIM having only one subscriber identification information.

Furthermore, subscriber identification information exists in the ADF usim1 , ADF usim2, and the like. For example, a first ADF usim1 may be subscriber identity information is stored, may also be usim2 ADF is stored and a second subscriber identity information management.

Hereinafter, the process of changing the subscriber identity information of FIG. 4 is reviewed once again in the case of having the file structure of FIG.

In the subscriber authentication step (not shown), the terminal 110 can perform the subscriber authentication procedure for the first communication network using the main subscriber identification information transmitted from the smart card including the plurality of subscriber identification information.

Accordingly, when the subscriber authentication process is performed while the subscriber station 110 is booting using the smart card having the file structure of FIG. 7, the smart card has compatibility with a general smart card including only one subscriber identification information The terminal 110 provides the subscriber identification information stored in the ADF usim , which is a default application specific file (ADF), to the subscriber terminal 110, The subscriber authentication process may be performed in a manner similar to the process in FIG.

In step S410, the terminal 110 receives a part or all of the plurality of subscriber identification information from the smart card, displays each subscriber identification information in an active or inactive state, To the user. For example, it is possible to provide a user with a part or all of the plurality of subscriber identification information stored in the smart card by using an application (app) driven in the terminal 110, such as a smart phone, The user can be informed of whether to renew the subscriber identity using the subscriber identity.

In step S420, the subscriber station 110 transmits a predetermined command to the smart card to set the first subscriber identification information selected by the user as main subscriber identification information and activate the smart card. The main subscriber identification information can be deactivated.

At this time, the terminal 110 transmits an ISO command or the like for driving the smart card to the smart card. In response to the received command, the smart card transmits an element file EF ) To an application specific file (ADF) including the first subscriber identification information selected by the user (for example, changing the link to ADF usim2 as shown in FIG. 6) (For example, copying the subscriber identification information of ADF usim2 to ADF usim in FIG. 6) with the element file EF corresponding to the identification information.

Further, even when the user reboots the terminal 110 later, the main subscriber identification information finally selected by the user is maintained in the smart card, so that the terminal 110 can perform the subscriber authentication procedure using the same.

Lastly, in the subscriber authentication update step (S430), the subscriber entity 110 updates subscriber authentication for the first communication network 130 using the main subscriber identity information. Accordingly, the terminal 110 accesses the first communication network 130 with new subscriber identification information, such as changing the telephone number of the terminal 110 according to the first subscriber identification information selected by the user .

At this time, in the subscriber authentication update step S430, the terminal 110 cancels the authentication for the first communication network 130 without rebooting the terminal 110, The subscriber identification information for the terminal 110 can be updated by performing the subscriber authentication procedure for the first communication network 130 again using the main subscriber identification information.

Further, in the subscriber authentication update step S430, the subscriber station 110 cancels the authentication for the first communication network, receives the main subscriber identity information from the smart card, The authentication procedure may also be performed.

By updating the subscriber identification information for the subscriber station 110 through the above-described series of steps, the user does not need to carry a smart card such as a USIM or a need for performing a cumbersome smart card replacement operation The subscriber identification information of the terminal can be updated quickly and easily.
