Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms and words used in the present description and claims should not be construed as limited to ordinary or dictionary meanings, and the inventor should properly interpret the concepts of the terms in order to describe their invention in the best way. It should be interpreted in accordance with the meaning and concept consistent with the technical idea of the present invention based on the principle that it can be defined. Therefore, the embodiments described in this specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention, and not all of the technical ideas of the present invention are described. Therefore, It is to be understood that equivalents and modifications are possible.

The present invention provides a separate storage unit for storing communication information including authentication and registration information stored in the SIM card in the modem terminal, thereby shortening the boot time of the modem terminal and resuming quick communication. A SIM (Subscriber Identification Module) card that is installed in the modem terminal and stores communication information including unique number, subscriber information, and information for performing communication; An authentication registration unit for performing authentication and registration procedures with the base station using the communication information stored in the SIM card, and a storage unit for storing communication information stored in the SIM card when the authentication and registration procedure of the authentication registration unit is completed, When the modem terminal is reset or rebooted, And performs authentication and registration procedures with the base station using communication information stored in the storage unit rather than communication information stored in the SIM card.

FIG. 1 shows a configuration diagram of a modem terminal using a SIM card with a shortened boot time according to an embodiment of the present invention.

As shown in the figure, the modem terminal 100 of the present invention includes a SIM card 110, an authentication registration unit 120, and a storage unit 130. After the authentication procedure and registration procedure with the base station 200, The modem terminal can perform communication.

Here, the modem terminal 100 is a terminal for using a wireless service, and is configured in such a way as to use a communication network such as 2G, 3G, or 4G, and is used for a feature phone, a smart phone Phone, a data modem, a card settlement device, and so on.

Meanwhile, the SIM card 110 installed in the modem terminal is an IC (Integrated Circuit) card implementing a subscriber identification module and is an essential element of a GSM (Global System for Mobile communication) terminal. Generally, a slot is formed in the back of the terminal, and a method of inserting the slot is used, but various positions can be implemented.

The SIM card 110 has an IC card (Integrated Circuit Card ID) and an International Mobile Subscriber Identity (IMSI), which are unique numbers of the SIM card 110. The SIM card 110 also includes subscriber information, .

However, when the SIM card having such advantages is mounted on the terminal and used, the SIM card is activated every time the terminal is booted, the status is confirmed, the information stored in the SIM card is read, And the like.

This is because it takes a very long time to perform the sequence of steps in sequence at every boot. Therefore, the present invention further includes a separate storage unit 130 for shortening the boot time, and a description thereof will be given later.

The authentication registration unit 120 of the present invention performs an authentication and registration procedure with the base station 200 using the communication information stored in the SIM card.

The authentication and registration procedure is a series of procedures for using a communication network provided by a communication company, and allows a modem terminal to be connected to a communication network by communicating with a base station using user information and information for performing communication.

In addition, the present invention further includes a separate storage unit 130 in the modem terminal. The storage unit stores various information stored in the SIM card when the authentication and registration procedure of the authentication registration unit is completed. When the modem terminal is reset or rebooted, the authentication registration unit does not store the communication information stored in the SIM card And performs authentication and registration procedures with the base station using the communication information stored in the storage unit.

The storage unit 130 may include a flash memory or a flash memory only. The flash memory is a storage unit that does not erase the stored information even when the power supply is cut off. The storage unit 130 has a feature that the power consumption is small and information input / . There are two types of data storage type (NAND) with high storage capacity and code storage type (NOR) with high processing speed. The former can be highly integrated and can replace the hand disk, There is an advantage that it is widely used for storage.

By using the storage unit 130, it is possible to activate the SIM card, check the status of the SIM card, read the information stored in the SIM card, It is possible to simplify the authentication and registration procedure with the base station using only the information stored in the storage unit regardless of whether the card is in the state or not.

Of course, since the information in the SIM card can be changed, the present invention compares the communication information stored in the SIM card with the communication information stored in the storage unit after the authentication and registration procedure is successfully performed, And updating the communication information stored in the SIM card to be the same as the communication information stored in the SIM card.

This minimizes the time required for the SIM card every time the modem terminal is booted, thereby reducing the waiting time of the user and improving the usability and reliability.

FIG. 2 is a flowchart illustrating a method of shortening a boot time of a modem terminal using a SIM card according to an embodiment of the present invention.

First, the modem terminal is booted (S10). At this time, the information stored in the SIM card has not been read yet, and no information is stored in the storage part. Therefore, additional information is required to perform the authentication procedure and the registration procedure with the base station for connection of the communication network.

Thereafter, the SIM card is read (S20), and the SIM card stores communication information including a unique number, subscriber information, and information for performing communication. In order to read the SIM card, it is more preferable that the SIM card activation step and the SIM card status confirmation step are performed first.

Then, the authentication registration unit performs the authentication and registration procedure with the base station using the communication information (S30). This is a procedure for using a communication network of a communication company provided in 2G, 3G or 4G, and is an indispensable procedure for communication using a modem terminal.

Thereafter, the storage unit stores the communication information stored in the SIM card (S40). Since the storage unit includes the flash memory, the stored information is not lost even when power is not continuously supplied.

Then, the modem terminal is reset or rebooted (S50). The modem terminal may be reset or rebooted for various reasons such as intentional reboot of the user, reboot due to failure, reboot due to power supply change, and the reset or reboot may be performed to an appropriate degree even for updating the storage unit .

Then, the authentication registration unit re-performs the authentication and registration procedure with the base station using the communication information stored in the storage unit (S60). At this time, authentication and registration are performed only by the information of the storage unit regardless of the current state of the SIM card.

In this case, even if the SIM card is removed from the modem terminal, there is a risk that the authentication and registration procedure with the base station can be performed. However, there is a means for identifying the existence of a separate SIM card, The presence or absence of the SIM card can be grasped by means of comparing the presence or absence of the SIM card.

In addition, since the information stored in the SIM card can be changed, the communication information stored in the SIM card is compared with the communication information stored in the storage unit (S70). If there is a change, the communication information stored in the storage unit is transmitted to the SIM card And updates it to be the same as the communication information (S80). So that the storage unit can have the same information as the information stored in the SIM card.

Each of the above steps allows the modem terminal equipped with the SIM card to be connected to the communication network at a higher speed when the modem terminal is reset or rebooted.

As a result, the present invention is advantageous in that security is enhanced, convenience of the user is improved, and a more stable modem terminal is provided by using a SIM card attached to the modem terminal.

Further, the present invention provides a separate storage unit capable of storing communication information including authentication and registration information stored in the SIM card in the modem terminal, thereby shortening the boot time of the modem terminal required by the SIM card, There is an advantage to be able to resume.

While the present invention has been described with reference to the specific embodiments, it is to be understood that the invention is not limited thereto. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents. Various modifications and variations are possible.
