File 521 may be configured. The ADF usim file 521 managing USIM file information among the ADFs may be linked to an element file (EF) DIR 513 accessed by the MF 501.

Meanwhile, element files (EFs) 541, 542, 543, and 544 necessary for a mobile communication network are configured to each of the DFs 531 and 532 (DF GSM_ACCESS) and DF ISIM_ACCESS under the ADF usim file 521. EF ICCID 541 corresponding to the dual USIM serial number, user identification number EF IMSI 542 on the network, EF MSISDN 543 corresponding to the telephone number, and a key for accessing the network. Files such as EF Kc 544 that manages information can be constructed.

The terms used in the file structure described in the present invention are not used to limit the interpretation to a specific meaning, but are used as examples for better understanding of the description. Accordingly, the embodiments of the present invention may be equally applied even if the term is defined in different terms in various types of file structures for constructing a USIM file.

For example, the EF may mean a file of the final stage having actual data. In addition, the ADF does not have actual information, but may serve as an information folder including a plurality of EFs internally. According to various embodiments of the present disclosure, the ADF may be included in another ADF having a tree structure.

The DF may function the same as or similar to the ADF. According to various embodiments of the present disclosure, the DF does not have a file index indicating the file and the OS cannot directly access the file. However, the ADF is a file in which a file index representing the file exists.

The MF is a topmost ADF of a tree structure, and may have a plurality of EFs and ADFs internally. On the other hand, it cannot have any file at the same level as the top of the MF.

If only the main part shown in FIG. 5, it can be shown as shown in FIG. Referring to FIG. 6, an EF DIR 611 may be configured below the MF 601, and the EF DIR 611 may be linked with a specific ADF usim 621. A plurality of DFs 631 may be formed under each of the ADF usims 621, and a plurality of EFs 641, 642, 643, and 644 may be configured in each DF 631 as described above. have.

7 is a flowchart illustrating a booting procedure of an electronic device and a multi-subscriber information processing smart card according to an embodiment of the present disclosure. Referring to FIG. 7, a booting procedure between an electronic device and a multi-subscriber information processing smart card (eg, USIM) will be described in detail using the USIM structure.

First, when the power of the electronic device is turned on, the electronic device checks whether the USIM exists and the state of the USIM by requesting general information of the skat card (ATR / PPS processing) (step 704).

After confirming that the USIM operates normally after confirming the existence of the USIM, the multi-subscriber information processing smart card selects the MF file according to the profile information request of the electronic device (step 704).

If the selection of the MF file is successful (OK) (step 706), the DF and the EF existing below the MF file are checked (step 708), and the existence of the double EF DIR and the existence of information exist. If the EF DIR exists (step 710), the ADF USIM linked with the EF DIR is accessed. When accessing the ADF USIM using the link information, files such as EF IMSI, EF ICCID, EF MSISDN, EF Kc, etc. existing in the ADF USIM are read (steps 712 and 714).

In step 706, if the selection of the MF file fails, after resetting (step 716), it may be implemented to retry the selection of the MF file a predetermined number of times (step 704). If the retry fails a predetermined number of times, the processor may be terminated after indicating that an abnormal state has occurred.

8 is a signal flowchart illustrating a booting procedure between an electronic device and a multi-subscriber information processing smart card according to an embodiment of the present disclosure. Referring to FIG. 8, a booting procedure between an electronic device and a multi-subscriber information processing smart card (eg, USIM) will be described in detail using the USIM structure.

First, when the power of the electronic device 110 is turned on (step 802), the smart card general information (ATR / PPS, etc.) may be requested (step 804) from the multi-subscriber information processing smart card 120. The multi-subscriber information processing smart card 120 may check the ATR / PPS information (step 806) and respond to the electronic device 110 (step 808).

Upon receiving the ATR / PPS information, the electronic device 110 may request the subscriber profile information from the multi-subscriber information processing smart card 120 (step 810). In response to the request, the multi-subscriber information processing smart card 120 may select an MF (step 812) and transmit the selected MF to the electronic device 110 as a response. 8 illustrates an example in which one MF exists and one ADF file exists to assist in understanding the present invention. However, according to various embodiments of the present disclosure, a plurality of MFs exist and an ADF file exists. Modification can be applied when a plurality of these exist.

The electronic device 110 requests the directory link file information from the multi-subscriber information processing smart card 120 (step 816), and the multi-subscriber information processing smart card 120 selects the EF DIR according to the request (step 818). In operation 820, the ADF file may be transmitted to the electronic device 110 as a result of the response. Next, the electronic device 110 may request IMSI information from the multi-subscriber information processing smart card 120 (step 822), and the multi-subscriber information processing smart card 120 checks the EF IMSI according to the request ( In operation 824, the IMSI value may be transmitted to the electronic device 110 in operation 826.

The electronic device 110 may receive an IMSI value from the multi-subscriber information processing smart card 120 and perform processing logic according to the received IMSI value (step 828). According to the processing logic, the electronic device 110 may request MSISDN information from the multi-subscriber information processing smart card 120 (step 830), and the multi-subscriber information processing smart card 120 may request an EF according to the request. In operation 832, the MSISDN may be checked, and the MSISDN value may be transmitted to the electronic device 110 in response.

The electronic device 110 may perform processing logic based on the received MSISDN value (step 836).

Hereinafter, a method of changing multiple subscriber numbers by applying the aforementioned FIGS. 7 and 8 will be described.

9 is a diagram illustrating a file structure of a multi-subscriber information processing smart card according to an embodiment of the present invention. Referring to Figure 9, the structure of the USIM for multiple subscriber number support is shown. The USIM for multi-subscriber number support may be referred to as a 'multi-subscriber information processing USIM' or a 'multi-subscriber USIM' as a multi-subscriber information processing smart card. An EF DIR 911 may be configured under the MF 901, and a specific EF DIR 911 may be linked with a specific ADF usim 921. Each DF 911 (DF GSM_ACCESS) below the ADF usim 921 may be configured with element files (EFs) 941, 942, 943, and 944 necessary for accessing a mobile communication network, and a dual USIM serial number. EF ICCID (941) corresponding to the user identification number EF IMSI (942) on the network, EF MSISDN (943) corresponding to the telephone number, EF Kc (944) that manages key information for network access Files may be configured.

On the other hand, as shown, unlike the general USIM, there is no ADF usim 921, which is the default ADF for multi-number support, unlike ADF usim1 921a, ADF usim2 921b, unlike FIG. 5 described above. Data such as ADF usim3 921c and ADF usim4 921d may be stored, and ADF files may exist as a source data space for moving or copying information when selecting each data.

ADF usim1 (921a), ADF usim2 (921b), ADF usim3 (921c), ADF usim4 (921d), etc. may exist all the EF files required on the existing ADF usim (921).

Since the ADF usim file exists in the multi-subscriber USIM by default, and the corresponding ADF usim is configured to be linked to the EF DIR, there is no problem in compatibility with the general USIM. Each subscriber has information in ADF usim1 921a, ADF usim2 921b, ADF usim3 921c, ADF usim4 921d, and the like.

Four times to ADF usim1 (921a) for first opening, ADF usim2 (921b) for second subscriber / number opening, and ADF usim3 (921c) for third subscriber / number opening? When opening a subscriber / number, it may be stored and managed in the order of ADF usim4 (921d).

First, it is assumed that only two subscribers / numbers are opened to assist in understanding various embodiments of the present invention. The process described below is similarly handled even when there are two or more subscribers / numbers.

In the multi-subscriber USIM and the terminal booting process, the USIM procedure described above with reference to FIG. 7 may be applied. In addition, the USIM procedure described above with reference to FIG. 8 may be applied to the booting procedure in the electronic device.

Meanwhile, according to various embodiments of the present disclosure, a difference described later may occur in a process of moving a second number after opening the first number or moving between numbers.

For example, a user may apply for a new number, not an existing number, in which case it may be a new number of an existing nominee and / or the user, or a new number for a case where the nominal and the user are different.

The mobile service provider for which the user applies for a new number is set to ADF usim1 (921a) on the existing ADF usim 921 of the multi-subscriber USIM through online and offline interworking with the sales computer system. Change the link information to ADF usim2 (921b) or copy each file information from ADF usim (921) from the ADF usim1 (921a) file to the ADF usim2 (921b) file and use ADF usim (921) for ADF usim1 (921a) It is possible to open the subscriber information of ADF usim2 921b rather than the subscriber information.

In the carrier's sales computer system, the information of ADF usim2 (921b), rather than the existing ADF usim1 (921a), can be recognized as new USIM information that is not opened on the existing sales computer. Will have the same effect. As such, in the state changed to ADF usim2 921b, the same procedure as that of opening a new USIM to all existing processes may be applied.

In other words. As shown in FIGS. 11 and 12 to be described later through the above process, the link file linked to the ADF usim 1121 is changed from ADF usim1 1131 to ADF usim2 1132 or ADF usim ( According to the method of copying each EF file information on the ADF usim1 1231 from the information of the ADF usim1 1231 to the information of the ADF usim2 1232, a booting procedure of the electronic device may proceed. In the above process, the information on the ADF usim 1221 may be mapped to information of the ADF usim2 1232, and the opening process may be performed at the second number.

10 is a signal flow diagram illustrating a multi-subscriber management procedure between an electronic device and a multi-subscriber information processing smart card according to an embodiment of the present disclosure.

The current USIM is set to ADF usim1. For the case of changing the number to ADF usim2, the processing of the user smartphone app, the Android and iOS terminal logic, and the USIM may be processed as shown in FIG. 10.

For example, when the user wants to change the number from one number to another through the smartphone app, the smart card processing unit and the communication information processing unit of the smartphone OS may each perform a function.

The smartphone app means not only an application having a general user screen of Android and iOS, but also a SIM ToolKit program that manages and operates USIM information.

For example, when the multi-subscriber management application (smartphone app) executed in the electronic device 110 is executed and the inquiry about the existing number is requested, the card command is processed by the multi-subscriber information processing smart card 120 through the smartphone OS. Can be delivered (step 1002, step 1004). In the multi-subscriber information processing smart card 120, an existing subscriber number may be acquired (step 1006), and a response may be made (step 1008) to the smartphone OS. The smartphone OS may provide the acquired number to the smartphone app (step 1010), and the smartphone app may display the obtained number on the screen as shown in FIG. 14 (step 1012). When the user checks the plurality of subscriber numbers displayed on the screen and selects change to another subscriber number, the smartphone app sends a request including a number change card command to the smartphone OS (step 1014). The smartphone OS requests a number change card command from the multi-subscriber information processing smart card 120 (step 1016).

For example, when the user selects one number changed to another number, the smartphone app delivers the command function and the ISO command that executes the command to the smart card processing unit existing on the OS of the electronic device 110 to provide multiple subscribers. The information processing smart card 120 (eg, USIM) allows information to be changed.

That is, when the electronic device 110 requests the subscriber number change to the multi-subscriber information processing smart card 120 as described above, according to an embodiment of the present invention, the multi-subscriber information processing smart card 120 according to the above-described various methods ( For example, the subscriber number may be changed (steps 1018 and 1024) according to a method of changing link information of the ADF usim with information of ADF usim2 or copying and processing the corresponding information instead of ADF usim1 on the ADF usim.

According to the subscriber number change processing of the multi-subscriber information processing smart card 120, the processing result may be answered (steps 1020 and 1022) to the smartphone app through the smartphone OS. In addition, after the subscriber number change processing, the multi-subscriber information processing smart card 120 can know the refresh response (step 1026) to the smart phone OS, the smart card processing unit of the smart phone OS to the communication information processing unit USIM information change processing request (step 1028) can be made.

That is, when the ADF usim of the smart card is changed, in order to complete the processing of the change, the communication information processing unit of the smart phone OS should check the changed USIM information again and reconnect to the network.

The process of reacquiring USIM information by the communication information processor may include turning off and on the power of the electronic device 110 in response to a refresh request of the multi-subscriber information processing smart card 120 according to various embodiments of the present disclosure. A cold reset method for restarting through the device and a warm reset method for refreshing only USIM information without turning on / off power of the electronic device are possible. When applying the warm reset method, the user can change from one USIM information to another USIM information in a short time.

In addition, the cold reset method may be similar to a process between a general electronic device and a smart card processed from power-on, but the warm reset method does not reselect MF or ADF usim of the USIM like the cold reset method. Since Read EF IMSI or Read EF MSISDN is performed, all changed information must be moved on ADF USIM to process the function. Such processing can be performed as shown in Figs. 11 and 12.

As such, when the USIM change is completed, the smart card processing unit of the smart phone OS may request to disconnect the existing network to the communication information processing unit and reconnect to the network with the changed USIM (step 1028). In this case, a process of disconnecting an existing network and reconnecting to a network using a changed USIM may be displayed on the screen of the electronic device 110 (steps 1034 and 1054). When the above process is completed, the user's electronic device 110 may use the functions of the call and the wireless Internet with the changed USIM information instead of the existing USIM information. This allows a user to easily change and use multiple numbers with one electronic device (eg, a smartphone).

Referring back to FIG. 10, when the network suspension process is completed (step 1036), the communication information processing unit may acquire the USIM information from the multi-subscriber information processing smart card 120 through the smart card processing unit to reacquire USIM information (step 1038). Information may be requested (steps 1040 and 1042). The multi-subscriber information processing smart card 120 checks the USIM information (step 1044), and transmits the confirmed USIM information to the communication information processing unit (steps 1046 and 1048) through the smart card processing unit. The communication information processing unit registers the network with the changed USIM (step 1050), and transmits the network registration status to the smartphone app (step 1052), thereby displaying the network registration status on the screen (step 1054). . When the network registration process is completed (step 1056), the communication information processing unit completes the USIM change process (step 1058).

Files such as IMSI, EF MSISDN, information corresponding to a telephone number, and EF Kc, which manages key information for network access, may be configured.

On the other hand, as shown in the figure, unlike the general USIM, only the default ADF ADF usim (1121) for the multi-number support, data such as ADF usim1 (1131), ADF usim2 (1132) can be stored. have. Each subscriber has information in the ADF usim1 1131, the ADF usim2 1132, and the like. As described above, when the change of the subscriber number is requested from the electronic device, the link of the ADF usim 1121 to the information of the ADF usim2 1132 on the ADF usim 1121 instead of the ADF usim1 1131 on the ADF usim 1121. You can change the information.
