Description

Method and Apparatus for Saving Phonebook Data {Method and Apparatus for Saving Phonebook Data}

The present invention relates to an IC card, and more particularly, to a method and apparatus for storing telephone book data in an IC card connected to a portable terminal.

In general, a mobile communication terminal is provided with a phone book (ie, a phone book, phonebook) function. Therefore, the user may store data such as a necessary name, a corresponding telephone number (hereinafter, referred to as 'phone book data') in the phone book in advance, and later view and use it.

In particular, when the use of the IC card is determined as one of the basic specifications in the 3-generation mobile communication market, the phone book data is stored in the IC card, and the user using the 3G mobile communication service stores the IC card in which the phone book data is stored. The card can be inserted into the terminal and used. Accordingly, the user can avoid the hassle of having to upgrade the personal information such as phone book data by inserting the IC card used in the existing terminal in the new terminal when replacing the terminal.

Among the IC cards mainly used in mobile communication terminals, there are a subscriber identity module (SIM), a user identity module (UIM), and a universal subscriber identity module (USIM). .

The file structure of the IC card includes one master file (MF) corresponding to a root file, at least one dedicated file (DF) and an IC classified according to the service and application of the IC card. It is composed of an elementary file (EF) that stores data and information for service of a card. Thus, when the IC card storing the phone book data is inserted into the mobile communication terminal, the mobile communication terminal accesses the element files via a master file and a dedicated file associated with the phone book data in order to read the phone book data stored in the IC card. do.

That is, the mobile communication terminal reads a phone book reference (PBR) file, which is an element file, grasps the phone book data configuration of the IC card currently inserted in the mobile terminal, and then stores the phone book (ADN: Abbreviated dialing numbers) file. Element files (EF, Elementary) such as e-mail files, nicknames (SNE: second name entry) files, and additional phone book (ANR) files linked to the index administration phone book (IAP) file via Read the files. Of course, index files may not be used. If no index file is used, the nickname, additional phone book file can be mapped directly to the phone book file. At this time, each of the above-described element files may be stored in the EEPROM (Electrically Erasable and Programmable Read Only Memory) provided in the IC card.

Here, the phone book file is simply an element file for storing the names and phone numbers of people (hereinafter, referred to as 'subject') who want to save the phone book data, and the nickname file is the last name of the people stored in the phone book file. (family name) or nickname (Second Name) is an element file for storing, the additional phone number file is an element file for storing additional phone numbers other than the phone number stored in the phone book file.

However, according to the international standard (3GPP TS 31.102), a plurality of the same type of element files may be defined in the telephone book reference. For example, one or more additional phonebook files may be defined in the phonebook reference file. In addition, according to the international standard, when a plurality of element files of the same type are defined, the size and number of records allocated to each element file must be identical.

However, when users store a phone number in the phone book, it is common to store a basic phone number and one additional phone number for the same person. Therefore, when a plurality of additional phone book files are defined in the phone book reference file as described above, the storage space allocated to the second additional phone book file and / or the third additional phone book file is left as a surplus storage space. There is a problem.

For example, suppose a user creates two phone numbers by specifying two phone numbers for any one person. At this time, if two additional phone book files are defined in the phone book reference file, one phone number will be stored in the phone book file, and the other phone number will be stored in one additional phone book file. Therefore, there is a problem that the storage space allocated to the remaining additional phone book files is not used.

The present invention is to provide a method and apparatus that can efficiently utilize the storage space provided in the IC card.

In addition, the present invention is to provide a method and apparatus that can efficiently utilize the storage space provided in the IC card by varying the number of records allocated to a plurality of the same type of element files defined in the phone book file.

In this case, the controller 150 may control the portable terminal 100 to operate in the phonebook data input mode when a phonebook execution command is input. Here, the phone book data input mode is an operation for storing text data generated according to the user's input unit 110 in the storage unit 120 and / or the IC card 160 provided as the phone book data. May be a mode.

In addition, in the phone book data input mode, the input unit 110 generates a signal according to a user's operation and transmits the signal to the controller 150. Thereafter, the controller 150 may generate text data using the signal input from the input unit 110. In this case, the text data may include any one of name information (ie, text information about the subject's name), email information (ie, text information about the subject's email address), nickname information, basic phone number information, additional telephone number information, and the like. It may be abnormal.

In addition, in the phone book data input mode, the input unit 110 may generate a phone book storage command according to a user's operation and output the command to the controller 150. For example, when the input of the phone book data is completed, the user may operate a preset button or the like to store the input phone book data, and the input unit 110 generates a phone book storage command correspondingly to the controller ( 150).

Here, the input unit 110 may be a keypad or a touch pad or other various signal input devices.

The storage unit 120 may be a memory that stores data for controlling a general operation of the portable terminal 100 and / or data received through the IC card communication unit 130 (particularly, phone book data). Of course, the storage unit 120 may further store communication-related data for allowing a user to use a communication service. The storage unit 120 may be a semiconductor memory and may be a NAND memory.

The IC card communication unit 130 exchanges control signals and data with the IC card 160. For example, the IC card communication unit 130 receives an additional request signal for phonebook data from the control unit 150 to the IC card 160 and transmits the signal to the IC card 160 connected thereto. In addition, the IC card communication unit 130 receives the phone book data from the IC card 160 and transmits it to the control unit 150.

The display 140 may be activated or terminated by the control of the controller 150, and outputs the processed image data as visual information to the outside. For example, the phone book output image data received from the controller 150 is output as visual information that can be recognized by the user. The display unit 140 may include an LCD or a plasma display panel (PDP), and may further include components for functioning as a touch screen. However, since the configuration of the display unit 140 to perform the above-described function and additional configuration for functioning as a touch screen are obvious to those skilled in the art, a separate description will be omitted.

The controller 150 controls the overall operation of the portable terminal 100. For example, the controller 150 controls the operation of necessary components of the portable terminal 100 so that a function corresponding thereto is performed when various signals according to the manipulation of the input unit 110 of the user are input.

In particular, the controller 150 may control the generated text data to be stored in the IC card 160 when a phone book storage command is input from the input unit 120. In this case, the control unit 150 may transmit the generated text data to the IC card 160 through the IC card communication unit 130. Particularly, when a phone book storage command is input from the input unit 110, the controller 150 converts the text data inputted together with the phone book storage command into a file type according to an international standard (ie, an IC card 160). Storage space allocated for phonebook data storage).

Hereinafter, each functional unit of the IC card 160 connected through the IC card communication unit 130 will be described with reference to FIG. 1B.

1B is a configuration diagram of a functional unit of an IC card according to an embodiment of the present invention.

Referring to FIG. 1B, the IC card 160 includes a communication unit 170, an IC storage unit 180, and an IC control unit 190.

The communication unit 170 transmits and receives a control signal and data to and from the portable terminal 100 through the IC card communication unit 130. For example, the communication unit 170 receives an additional request signal of the phone book data and the phone book data from the IC card communication unit 130 and transmits it to the IC controller 190.

The controller 190 controls the overall operation of the IC card 100. For example, the IC controller 190 controls the operation of necessary components of the IC card 100 in order to perform a corresponding function when a control signal is input from the portable terminal 100 through the IC communication unit 170. do.

For example, when the IC controller 190 receives the phonebook data addition request signal and the phonebook data from the communication unit 170, the IC controller 190 transmits the phonebook data to the IC storage unit 180 and the IC storage unit 180. Control to add to the phonebook. The process of adding the phone book data to the phone book will be described in detail later with reference to FIG. 3.

The above-described IC card 160 uses a specific file structure to construct a phone book. The file structure is organized according to the international standard (3GPP TS 31.102). For better understanding of the present invention, the file structure of the UICC for storing phonebook data according to international standards will be described below with reference to FIG. 2.

2 is a diagram illustrating a file structure of a UICC for storing phonebook data according to an embodiment of the present invention.

Referring to FIG. 2, the logical file structure of the UICC is largely composed of one MF (Master File) and an essential element file.

In the file structure illustrated in FIG. 2, the MF 205 is the root directory of the UICC file structure, at least one dedicated file, where the dedicated file includes an application dedicated file and an element file. Can have For example, the MF 205 may include one ADF_USIM 210. ADF_USIM 220 is a kind of dedicated file that stores files related to USIM application, and forms a functional group, and may be composed of low-level dedicated files and element files. That is, the dedicated file may be formed of element files and group of element files of the same group for each application. For example, the ADF_USIM 220 of FIG. 2 may include a dedicated file DF_PHONEBOOK 230.

The EF_PBR 230 is a phone book reference file and includes file identifier (FID: File Identifier) information of the phone book related files defined in the DF_PHONEBOOK 230. EF_PBR 230 also includes one or more of a combination of three phonebook entries. The combination of the three phone book entries is as follows.

-Type 1 files: A file in which a reference file and a master file (phone book file) contain the same number of records and are linked based on record number.

Type 2 files: Files that are linked through pointers stored in the index administration file (EF_IAP) but fewer than the Master file.

Type 3 files: A file of type linked to a Record identifier that exists in the record.

At this time, the phone book entry combination according to an embodiment of the present invention includes a plurality of EF_ANR files as type 2 files.

For example, a plurality of additional telephone number files may be mapped to an EF_PBR 230 as additional telephone number related files through an index file. The above description briefly describes the file structure according to the international standard, which is obvious to those skilled in the art, and thus detailed description thereof will be omitted.

The IC card 160 constructs a phone book using the above-described file structure and stores the phone book data in the IC storage unit 180 according to the structure of the phone book. Hereinafter, a method of storing phonebook data according to an embodiment of the present invention will be described with reference to the file structure of FIG. 2 and FIG. 3. At this time, the controller 150 stores the name and basic phone number generated by the user's input unit 110 in the phone book file EF_ADN 250, and stores one or more additional phone numbers in the additional phone book file EF_ANR1. (270), EF_ANR2 (280) and Assume that the control is stored in the EF_ANR3 (290). It is also assumed that the portable terminal 100 reads the EF_PBR 240 file at boot time and grasps the phone book structure. In addition, the steps to be described below may be steps performed in each component included in the portable terminal 100 or the IC card 160 described with reference to FIG. 1, but for convenience of understanding and description, the portable terminal 100 ) Or collectively as is performed in the IC card 160.

3 is a flowchart illustrating a process of storing phonebook data according to an embodiment of the present invention.

Referring to FIG. 3, in step 305, the portable terminal 100 operates a phone book data (phonebook data) input mode according to a user's manipulation.

In operation 310, the portable terminal 100 generates additional telephone number information according to a user input.

In step 315, the portable terminal 100 accesses the MF 210 of the IC card 160 and selects the ADF_USIM 220 to store the generated basic telephone number and name as phonebook data.

In step 320 to step 325, the portable terminal 100 selects the DF_PHONEBOOK 230 when a normal response signal is received from the IC card 160 when the correct response signal for the ADF file selection is received.

In steps 330 to 335, when the portable terminal 100 receives a normal response signal from the IC card 160 for the DF_PHONEBOOK 230 file selection, the element file corresponding to the additional telephone number to be stored as the phonebook data. Select (EF). For example, the portable terminal 100 may select an EF_ANR1 270 file (additional phonebook file) to store the additional telephone number.

In steps 340 to 345, when the mobile terminal 100 receives a normal response signal from the IC card 160 with respect to the selection of the element file corresponding to the additional telephone number, the portable terminal 100 transmits an additional telephone number storage request signal to the selected element file. Transmit to 160.

In step 350, the IC card 160 stores the additional telephone number in an empty storage space of the selected element file and transmits a normal response signal to the portable terminal 100.

In step 355, the portable terminal 100 selects the EF_IAP 260.

In steps 360 to 365, when the mobile terminal 100 receives a normal response signal for storing the additional telephone number, the portable terminal 100 stores the EF_IAP in the IC card 160 to store the record number storing the additional telephone number in the EF_IAP 260. Send a signal.

In step 370 to step 375, when the IC card 160 receives the EF_IAP storage signal, the IC card 160 stores the record number storing the additional telephone number in the EF_IAP 260, and then transmits the normal response signal to the portable terminal 100. At this time, the record number of the EF_IAP 260 to store the record number storing the additional telephone number is the same as the record number of the EF_ADN 250 in which the basic telephone number for the same person is stored.

In the above-described process, a process for storing one additional phone number is illustrated, but EF_ANR1 (270), EF_ANR2 (280) and It is obvious that EF_ANR3 290 can be used to add two or more additional phone numbers for the same person.

Referring again to FIG. 1, the number of records of the element file stored in the IC card 160 is specified in advance in accordance with international standards. In particular, in a phone book entry combination (ie, type 2) of a type linked through a pointer stored in the EF_IAP 260, that is, the number of records of an element file of the same type included in the EF_PBR 240, as shown in FIG. And / or sizes are specified in international standards to be identical to each other.

However, since a user generally stores a basic telephone number and one additional telephone number for the same person, a file structure for storing three additional numbers as shown in FIG. 2 does not use the storage space efficiently. Therefore, the present invention sets the number of records of the element file of the same type differently so as to efficiently use the storage space. Hereinafter, a method of designating the number of records for efficient storage space use in the IC card 160 will be described.

4 is a diagram illustrating a file structure and a designated record according to an international standard, and FIG. 5 is a diagram illustrating a file structure and a designated record recognized by a portable terminal according to an embodiment of the present invention.

According to the international standard, when one EF_PBR 240 defines a plurality of element files of the same type, it is determined that each element file should have the same number and / or size of records. So EF_ANR1 (270), EF_ANR2 (280) and Since EF_ANR3 290 is an additional phonebook element file of the same type, EF_ANR1 270, as illustrated in FIG. EF_ANR2 (280) and EF_ANR3 290 should be set to include the same 200 records. Of course, in FIG. 4, it is assumed that 200 records are included in one EF_ANR. However, the number and / or size of records included in one EF_ANR may vary according to the manufacturer's setting of the IC card 160.

However, EF_ANR1 270 of FIG. 4, EF_ANR2 (280) and As described above, when the phone book is configured by using records corresponding to the EF_ANR3 290 (that is, 430, 440, and 450), waste of storage space may occur. That is, the user generally does not register a plurality of additional telephone numbers. Thus, EF_ANR2 280 and In general, all of the storage space allocated to EF_ANR3 290 is not used.

For example, an additional phone number is not registered among names stored in the EF_ADN 250 (that is, names (names, trade names, etc.) of persons (or corporations, businesses) that are subjects of various data stored in the phone book). Assume that there are 100 unnamed names, 50 additional names registered with 1 additional number, and 20 registered names with 2 additional numbers. At this time, if the number of records set in each EF_ANR is 200, EF_ANR1 (270), EF_ANR2 (280) and Of all the records set in the EF_ANR3 290 (that is, 430, 440, and 450 in FIG. 4), only the number of unused records is close to 550.

In order to solve this problem, in the present invention, in setting the number of records of each element file of the IC card 160, the element file is defined in each element file when defining a plurality of element files of the same type in the EF_PBR file, without being restricted by international standards. Allows you to set the corresponding number of records differently.

For example, referring to FIG. 5, the case where the number of records allocated to the EF_ANR2 280 is 100 and the number of records of the EF_ANR3 290 is 50 is illustrated. Accordingly, the controller 150 controls the IC card 160 to store the phone book data. Thus, the free memory corresponding to a record outside the range set according to the present invention can be used to generate a file of a kind other than the additional phonebook file. For example, you can increase the number of SMS messages stored from 20 to 100 by specifying the memory used as a record of the existing additional phonebook file as a record of the SM file (EF_SMS file).

Of course, the above description is limited to the additional phone book element file and the additional phone number, but it is obvious that the present invention can be applied to other element files without being limited thereto. For example, when a plurality of nickname (SNE) files are designated in one EF_PBR 240, different record numbers may be allocated to each nickname file as described above.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that the invention may be varied and varied without departing from the scope of the invention.
