Erasable and Programmable ROM (17), and I / O (Input / Output) circuit 19. Here, the EEPROM 17 is divided into several adjacent areas. Each area, called a unit, a block, a sector, or the like, can be individually written, read, and erased. International Mobile Subscriber Identity (IMSI), information to provide mobile terminal mobility (e.g., Local Area ID), basic information about accessible services, and its own implementation to run various applications The program is stored, and various information of the mobile communication terminal, for example, communication network related information or subscriber specific information, is stored in the form of an elementary file (EF).

The file structure of the subscriber information storage device includes one master file (MF) corresponding to a root file and at least one dedicated file classified according to subscriber information storage services and applications. DF) and an element file (EF) for storing data, information, and the like for the subscriber information storage service. Therefore, when the subscriber information storage device storing the subscriber information is inserted into the mobile communication terminal, the mobile communication terminal accesses the element files via the master file and the dedicated file associated with the subscriber information in order to retrieve the subscriber information. For example, in the case of subscriber information regarding a phone book, after reading the phone book reference (PBR) file, which is an element file, the phone book data configuration of the subscriber information storage device currently inserted into the mobile communication terminal is determined, and then ADN (Abbreviated Dialing) Data, such as an email file, a secondary name entry (SNE) file, and an additional number (ANR) file, which are linked to an index administration phone book (IAP) file, are read via a number file. Here, the ADN file is a file for storing the names and phone numbers of people who simply want to save as phone book data, the SNE file is a file for storing the family name or nickname of people stored in the ADN file. The ANR file is a file for storing additional phone numbers other than the phone numbers stored in the ADN file. Such an element file follows the standard defined in 3GPP TS 31.102, and each element file may be configured to be connected to each other by a pointer and recognized as if it leads to one item to the user. For example, the standard of the ADN file is as shown in Fig. 2, and each of the other element files are connected to each other by respective pointers set in the ADN file, so that a number of related to when a user calls a telephone number The element files can be implemented to lead to one phone number entry.

The control section 24 has a similar function to the CPU 11 of FIG. 1, in addition, sets an indicator for identifying each of the plurality of numbers assigned to the mobile communication terminal, and sets the phone in the subscriber information storage section 22. When subscriber information such as book information, text message information transmitted or received, messages and file information transmitted or received through a mobile messenger is stored, an indicator corresponding to the currently used number is matched and stored together. In addition, the control unit 24 sets an indicator that does not identify each of the plurality of numbers so that they can be called in common in all of the plurality of numbers, and matches the set indicator with the subscriber information when the subscriber information is stored. It may be stored in the subscriber information storage 22. At this time, the controller 24 preferably generates and stores an independent number mode element file for distinguishing each number mode currently used by the indicator matching the subscriber information. Detailed description thereof will be described later.

In addition, when the subscriber information is called by the user of the mobile communication terminal, the controller 24 calls and displays the subscriber information corresponding to the currently used number on the screen based on the indicator stored in the subscriber information storage 22. .

The OS storage unit 26 corresponds to the ROM 13 of FIG. 1, and stores an operating system (OS) program for driving the control unit 24 as described above.

4 is a diagram schematically illustrating a mobile communication terminal according to the present invention. Referring to the drawings, the mobile communication terminal 30 includes a subscriber information storage device 32 and a control unit 34.

The subscriber information storage device 32 may be the subscriber information storage device 10 of FIG. 1 or the subscriber information storage device 20 of FIG. 2. The subscriber information storage device 32 may be detachably mounted on the mobile communication terminal 30 to store subscriber information. Save it. When the subscriber information storage device 32 is mounted in the mobile communication terminal 30, the controller 34 interworks with the CPU 11 of the subscriber information storage device 32.

The control unit 34 sets an indicator for identifying each of the plurality, and matches and stores an indicator corresponding to the number currently used when the subscriber information is stored in the subscriber information storage device 32. In addition, the controller 34 sets an indicator that does not identify each of the plurality of numbers so that the controller 34 can be called in common in all of the plurality of numbers, and matches the set indicator with the subscriber information when the subscriber information is stored. It may be stored in the subscriber information storage device (32). In this case, as in the case of FIG. 3, the control unit 34 preferably generates and stores an independent number mode element file that matches the indicator matched to the subscriber information. Detailed description thereof will be described later.

In addition, when the subscriber information is called by the user of the mobile communication terminal, the controller 34 calls and displays the subscriber information corresponding to the currently used number on the screen based on the indicator stored in the subscriber information storage device 32. .

Here, the mobile communication terminal 30 may further include an indicator storage unit 36 for storing a predetermined indicator at the time of manufacture of the mobile communication terminal 30 or subscription of a plurality of number services. In this case, the control unit 34 sets the indicators stored in the indicator storage unit 36 to correspond to the plurality of telephone numbers, respectively, and stores the subscriber information by matching the indicator corresponding to the number currently used when the subscriber information is stored. It may be implemented to store in the device (32).

FIG. 5 is a flowchart illustrating a method of managing subscriber information by the subscriber information storage device of FIG. 3 and the mobile communication terminal of FIG. 4.

When a plurality of telephone numbers are assigned to the mobile communication terminal equipped with the subscriber information storage devices 10, 20, and 30, the control section 24, 34 sets an indicator for identifying each of the plurality of assigned numbers ( S101). Here, the indicator is a flag for identifying each of the plurality of telephone numbers assigned to the mobile communication terminal. For example, assuming that the mobile communication terminal has been given two telephone numbers, the control unit 24 is A flag of 00000001 (0x01) can be set corresponding to the telephone number of the home mode, and a flag of 00010000 (0x10) can be set corresponding to the telephone number of the business mode.

In addition, the controllers 24 and 34 generate a number mode element file for storing an indicator for distinguishing the currently used number mode (S103), and the user of the mobile communication terminal stores or transmits new data in the phone book data. Or when new subscriber information is stored by storing the received text message or data or file transmitted or received via the mobile messenger (S105), the indicator corresponding to the telephone number currently used in the generated element file. It is stored (S107). At this time, the indicators stored in the number mode element file are matched with the stored subscriber information. In this case, since the ADN file includes names and phone numbers of people who want to store the phone book data, the indicator corresponding to the currently used phone number is preferably stored in match with the ADN file. Here, the reason why the control unit 24, 34 generates the indicator file separately from the other subscriber information and stores it separately is to avoid the range defined in the standard for use of the subscriber information storage device. That is, subscriber information is stored in various file formats such as SNE file, ANR file, ADN file, etc. defined in the standard. When tagging the standard file defined or changing the header value, the mobility of subscriber information storage device is changed. Because it can hurt. That is, when the subscriber information storage device is separated from one mobile communication terminal and mounted on another mobile communication terminal, the new mobile communication terminal should be used in the same way as the previous mobile communication terminal. In this case, the mobility of the subscriber information storage device may not be guaranteed.

6 is a diagram illustrating the structure of a number mode element file generated for storing an indicator. If the stored subscriber information is phone book data, the width book data should be able to be called and updated by the user of the mobile communication terminal. Therefore, the access condition is preferably set to a personal identification number (PIN). The usage and content of the card is protected by a PIN. If PIN1 is defined to control the general use of the phone, PIN2 can be used for other special functions (e.g. a list that restricts calls to international numbers). Is defined. In addition, since the activation and deactivation of such an element file is preferably set by an administrator, the access state is indicated as being set to ADM1 (Administration 1). However, the setting of such an access state is not limited to that shown, and may be changed to various states.

 According to the attribute information of the number mode element file, an indicator for identifying a current number of one byte is stored. At this time, the number of records of the number mode element file is preferably equal to the number of records of the linked element file, for example, when linked to the ADN file. In the figure, a case where a plurality of numbers are set to two is shown.

Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and the present invention is not limited to the specific embodiments of the present invention without departing from the spirit of the present invention as claimed in the claims. Anyone skilled in the art can make various modifications, as well as such modifications are within the scope of the claims.
