Method and Apparatus for Refreshing Changed Breakdown of System File to Mobile Station}

The present invention relates to a method and an apparatus for refreshing a change history of a system file to a mobile communication terminal. In particular, a management file which sets a refresh mode to a mobile communication terminal for an element file (EF) changed by an over-the-air (OTA) in a general purpose IC card is stored, and according to the refresh mode It relates to a method and device for refreshing system file change history by the mobile communication terminal.

In general, a universal IC card (UICC) for storing system-related files for a mobile subscriber to use a mobile communication service is inserted into a 3G mobile terminal.

The general purpose IC card consists of a microprocessor and a memory chip, and stores various kinds of information of the user.

Here, the universal IC card typically includes a Universal Subscriber Identification Module (USIM) card in addition to a Subscriber Identification Module (SIM) card for mobile service subscriber authentication.

In addition, the universal IC card is a smart card for applying a communication service capable of transmitting broadband packet-based text, digitized voice, video, multimedia data at high speed, regardless of where the mobile terminal or computer users are in the world. It is combined in the communication service terminal and can store user data along with authentication data.

1 is a diagram illustrating a system for providing an over-the-air (OTA) service to a general mobile communication terminal.

Referring to FIG. 1, the OTA server 110 transmits information related to a system to the mobile communication terminal 150 through the mobile communication network 130 using the OTA technology. Here, the information related to the system includes information values, applications, contents, and the like for controlling, and the mobile communication service subscriber can be provided with various services remotely without having to go directly to the store through the OTA technology.

As described above, when the mobile communication terminal 150 receives information related to an application or a system from the OTA server 110, the mobile communication terminal 150 stores the received information in a general purpose IC card coupled to the mobile communication terminal 150.

If there is a change in the information of a file stored in the universal IC card remotely by the OTA, the universal IC card recognizes the change made to the mobile communication terminal 150 by using a refresh command supported by the universal IC card.

Therefore, the process of resetting the mobile communication terminal 150 is necessary. That is, when the charging related file is changed while performing the mobile communication service using the charging related file in the mobile communication terminal 150, the mobile communication terminal 150 receives only the change history of the charging related file from the universal IC card. Since it is difficult to reflect the change history, a process of resetting the mobile communication terminal 150 is required.

Therefore, since the method of reflecting the change history to the mobile communication terminal 150 is different for each file whose information is changed by the OTA in the general purpose IC card, when the information of the file is changed by the OTA, the change history is displayed in the mobile communication terminal ( There is a need for an efficient method for reflection in 150).

An object of the present invention is to provide a method and apparatus for applying a change history to a mobile communication terminal when information of a file stored in a universal IC card is changed by OTA.

In order to achieve the above technical problem, the present invention provides a method for refreshing a change history of system file information from a universal IC card (UICC) to a mobile communication terminal, the method comprising: a) at least one system file; Generating and storing a refresh mode information file that stores information on which a refresh mode is set; b) determining whether an information change request of a system file is received; c) if it is determined that an information change request of the system file is received, changing the information of the system file stored in the general purpose IC card and confirming the refresh mode set in the corresponding system file through the refresh mode information file; And d) executing a command corresponding to the refresh mode set in the corresponding system file to recognize the change history according to the information change of the system file to the mobile communication terminal.

In addition, the present invention is a Universal IC Card (UICC) for refreshing the change history of the system file information to the mobile communication terminal, the refresh mode (Mode) for at least one system file and the system file A system file storage unit configured to store a refresh mode information file configured to store the set information; And when the information change request of the system file is received, changing the information of the system file to the mobile communication terminal by using a predefined command according to the refresh mode confirmed through the refresh mode information file stored in the system file storage unit. It includes a control unit for recognizing the details.

According to the present invention, a refresh method is defined for each system file changed by the OTA, and when the system file is changed by the OTA, it is automatically reflected to the mobile terminal according to the defined refresh method, so that a user of the mobile communication service separately operates. There is an effect of providing a convenience that can normally use a mobile communication service without.
