Description

METHOD FOR PROVIDING MULTI NUMBER SERVICE [0002]

An embodiment according to the concept of the present invention relates to a method of providing a multi-number service, and in particular, by storing a plurality of sets of subscriber identification information in a smart card, for example, a Universal Integrated Circuit Card (UICC) Numbered service providing method capable of managing a plurality of sets of subscriber identification information.

The Universal Integrated Circuit Card (UICC), which is referred to as a general purpose IC card, is a major component of a general-purpose mobile communication system, and is implemented as an extended SIM (Subscriber Identity Module) card.

The UICC can be inserted into the terminal and used as a module for user authentication, and the UICC can store personal information of a user and carrier information of a mobile communication carrier to which a user subscribes.

However, one UICC has a limitation that only one ICCID (Integrated Circuit Card ID), an International Mobile Subscriber Identity (IMSI), and an MSISDN (Mobile Station International ISDN Number) can be stored according to the standard.

SUMMARY OF THE INVENTION It is a technical object of the present invention to provide a method and apparatus for managing a plurality of sets of subscriber identification information by a single user terminal by storing a plurality of subscriber identification information sets in a smart card, for example, a Universal Integrated Circuit Card (UICC) To provide a multi-number service.

A method for providing a multi-number service using a smart card according to an exemplary embodiment of the present invention includes receiving a plurality of subscriber identification information (ID) stored in a file system of the smart card, Selecting one of the sets of subscriber identity information and setting a file path of the file system according to the selected set of subscriber identity information.

According to an embodiment, the step of setting the file path may set a file path so that a Universal Subscriber Identity Module (USIM) application can access a selected set of subscriber identity information.

According to an embodiment, the step of setting the file path may set a file path for master files corresponding to the selected set of subscriber identity information.

According to an embodiment, the smart card may be a Universal Integrated Circuit Card (UICC).

According to an embodiment, the plurality of subscriber identity set may include an Integrated Circuit Card ID (ICCID), an International Mobile Subscriber Identity (IMSI), a Mobile Station International ISDN Number (MSISDN), and a key for network connection have.

According to an embodiment, the step of setting the file path may be directly performed by the subscriber identity set management application.

According to an embodiment, the step of setting the file path may be performed through a Universal Subscriber Identity Module (USIM) application.

The method according to an embodiment of the present invention can store a plurality of sets of subscriber identification information in a smart card, for example, a Universal Integrated Circuit Card (UICC), so that a plurality of telephone numbers can be used as one user terminal .

In particular, each of the plurality of sets of subscriber identity information includes an ICCID, an International Mobile Subscriber Identity (IMSI), a Mobile Station International ISDN Number (MSISDN), and key information used for network connection . In this case, unlike managing only a plurality of phone numbers, one physical smart card can manage the user's name (e.g., IMSI) and key information for each of a plurality of smart card identification information (e.g., ICCID). That is, in addition to the service for providing a plurality of telephone numbers according to the present invention, a variety of services can be implemented, such as the use of personal names of corporation users and the use of prepaid plan names of postpaid plan users.

Also, according to the method according to the embodiment of the present invention, the user can manage a telephone number to be used by himself / herself by adding or deleting a plurality of sets of subscriber identity information stored in one UICC.

Also, according to the method of the present invention, the user terminal and the management server can provide a service specialized for a plurality of sets of subscriber identity information.

The USIM application 16 is operated to perform various functions required for network connection and subscriber authentication of the first terminal 100. [

The USIM application 16 may transmit a set of subscriber identification information stored in the UICC file system 12 outside the UICC 10 during network connection and subscriber authentication.

In accordance with the embodiment, the USIM application 16 may relay the SETTING2, which is performed between the subscriber identity set management application 14 and the UICC file system 12.

According to the embodiment, the first terminal 100 can manage the address book, the character receiving / receiving history, or the call receiving / receiving history corresponding to the subscriber identification information set. The first terminal 100 may activate an address book, a character receiving / receiving history, or a call reception / receipt corresponding to the set of activated subscriber identification information, according to the set of activated subscriber identification information. In particular, when a call is made to a telephone number included in an address book corresponding to a specific subscriber identification information set, the first terminal 100 transmits a command (CMD) for activating a subscriber identification information set corresponding to the address book to the UICC 10 ).

According to another embodiment, the first terminal 100 can manage an application group displayed on the background screen for each set of subscriber identity information. In this case, the first terminal 100 may display an application group corresponding to the activated subscriber identification information set on the background screen according to the set of activated subscriber identification information.

According to another embodiment, the first terminal 100 may provide an information protection service for each set of subscriber identity information. For example, an address book, a character acquisition / demodulation history, or a call reception / receipt corresponding to at least one subscriber identification information set requiring information protection among a plurality of subscriber identification information sets may be stored in the UICC 10, the first terminal 100, And may be stored in a separate server outside the first terminal 100. In this case, the address book, the character receiving / receiving history, or the call receiving / receiving details may be encrypted and stored. For example, the encryption may be encrypted using a cryptographic key in the UICC 10.

According to another embodiment, the first terminal 100 may manage contents (e.g., picture files, voice files, moving picture files, etc.) according to subscriber identity information sets. In this case, the first terminal 100 can set only the contents corresponding to the activated subscriber identification information set to be able to be checked according to the active subscriber identity set.

According to another embodiment, the first terminal 100 may provide a secret phone service for each set of subscriber identity information. In this case, when a character or a telephone is received by a specific subscriber identification information set, the first terminal 100 does not display it on the first terminal 100, and information on the received character or telephone is stored in the UICC 10 . Also, the first terminal 100 may transmit a text message or a voice message to notify the caller of the text or telephone that the current contact is difficult.

According to another embodiment, the first terminal 100 may set the usage right of the application for each set of subscriber identity information. In this case, the first terminal 100 may restrict the use of a specific application (e.g., a game application, etc.) when specific subscriber identification information is activated. Also, the usage right of the application for each subscriber identity information set of the first terminal 100 may be set by an external terminal (e.g., a terminal of the company security manager).

According to another embodiment, the first terminal 100 may manage a public certificate for each set of subscriber identity information. In this case, the first terminal 100 can set the authorized certificate corresponding to the set of activated subscriber identification information to be used as a default, according to the set of activated subscriber identification information.
