BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a mobile terminal, wherein an overhead that occurs when a record area load of a subscriber identity module (SIM) card (hereinafter, referred to as a SIM card) is loaded. The present invention relates to a sim card record processing method capable of quickly loading a large amount of information stored in a sim card and a portable terminal using the same.

SIM card is a module in the form of a card that can be used in a mobile terminal is a chip that stores personal information to provide a variety of services, such as subscriber authentication, billing, security functions. These SIM cards can be dialed to their phone numbers in any region regardless of mobile communication technology standards such as Code Division Multiple Access (CDMA) or Global System for Mobile communication (GSM). It was developed to make mobile communication freely available.

Some of the SIM cards, which are made of a certain amount of subscriber identification module, have a function of reducing charges for each call and recharging them. The subscriber identity module for the Universal Mobile Telecommunications System (UMTS), which is the third generation mobile communication among SIM cards, is also called a Universal Subscriber Identity Module (USIM).

Currently, when booting a mobile terminal, first, a SIM card telephone book record and a short message service (SMS) record are loaded. This is because when a mobile terminal is booted and loads a lot of data stored in the SIM card after the application is driven, a booting time takes too much time. For example, loading 100 data stored on a SIM card can take as long as 20 seconds to as long as 1 minute. This time consuming increase in proportion to the amount of data stored in the SIM card, which causes a great inconvenience to the user.

In detail, the READ RECORD and WRITE RECORD commands for reading / writing the conventional SIM card could read only one specific record as shown in FIGS. 1 and 2.

Accordingly, since the conventional SIM card can read and write only a specific record, an overhead occurs when reading and writing several records. That is, since only one record can be read in the related art, as many command-response procedures as the number of records are required. For example, when 10 records are read, a total of 20 communications are performed, with 10 commands sent from the mobile terminal to the SIM card and 10 responses sent from the SIM card to the mobile terminal. Therefore, the overhead according to the Command-Response procedure by the number of records increases.

Therefore, the present invention was devised to solve the above-mentioned problems of the prior art, and an object of the present invention is to reduce the overhead that occurs when loading information from a SIM card at the time of booting of a mobile terminal. It is to provide a sim card record processing method for fast processing and a portable terminal using the same.

3 to 7, in the method of reading a SIM card record according to an embodiment of the present invention, the portable terminal controller transmits a READ RECORDS command to the SIM card (S301).

In step S301, when the SIM card is mounted in the portable terminal and the booting of the portable terminal is started, the portable terminal controller recognizes the SIM card mounted in the portable terminal and transmits a command to read record data stored in the SIM card. . Here, the SIM card may be any one of SIM, USIM, and RUIM. For simplicity, the SIM card will be described as a representative.

Next, the data corresponding to the record of the SIM card internal storage space is read (S303).

In step S303, the portable terminal controller reads record data of the SIM card. In this case, one command, READ RECORDS, may be transmitted for the entire record of the SIM card, but preferably, a predetermined amount of record data that can be accommodated by a buffer included in the controller of the mobile terminal for smooth data transmission and reception. Send one READ RECORDS command to the group.

In step S303, the SIM card checks whether an error occurs while reading data (S305), and if an error occurs, immediately transmits a response to the portable terminal controller (S307).

Further, in step S303, the prescribed size of the data responding to the read data is compared (S309). If the data is larger than the size of the buffer, the data can be divided into several times and transmitted (S311).

Next, when the SIM card reads the corresponding record data group, the SIM card may return to step S307 to send a response to the command.

Next, the portable terminal controller performs a process on a response (S313).

In step S313, when receiving a response, the portable terminal controller determines whether there is record data to be read further in the SIM card. At this time, if there is record data to be read further in the SIM card, a new read command, READ RECORDS, is transmitted to the SIM card, otherwise communication is completed.

Here, whether the record data to be read further to the SIM card may be indicated in a response transmitted by the SIM card, and the mobile terminal controller receiving the response determines whether to proceed according to the display. Can be.

Hereinafter, a method of writing a SIM card record will be described with reference to FIGS. 4, 6, and 7.

In the method of writing a SIM card record according to an embodiment of the present invention, first, the portable terminal controller transmits a WRITE RECORDS command, which is a SIM card write command, to the SIM card (S401).

Next, the SIM card writes data to the corresponding record as long as the record length corresponding to the data (S403).

Next, it is checked whether an error occurs during the data writing (S405). If an error does not occur in the above, the data writing is completed in the corresponding record, and then a response to the write command is transmitted to the portable terminal controller (S407).

In step S405, if an error occurs during data writing, a response is immediately transmitted to the portable terminal controller (S409).

Next, the portable terminal control performs a process for a response transmitted from the SIM card (S411).

Sim card record processing method of the present invention according to the above method, if you need to perform a large number of READ RECORD / WRITE RECORD command, can reduce the overhead caused by this, it can be expected to improve the boot speed .

For example, as shown in FIG. 7, when reading 10 records, in the best condition, a command transmitted from the mobile terminal to the SIM card is one time, and a response transmitted from the SIM card to the mobile terminal is one. One time, the overhead can be greatly reduced, and the record processing speed stored in the SIM card can be improved.

The sim card record processing method of the present invention can process a large number of records with only one READ RECORDS / WRITE RECORDS command even when a program is written, thereby making programming easier.

In the above it has been described with respect to the SIM card record processing method according to an embodiment of the present invention.
