1 is an overall configuration diagram showing an entire system for backing up information stored in a smart card to a backup server according to the present invention.

The overall system shown in FIG. 1 shows an example in which information exchange between the smart card 100 and the communication terminal 150 is performed by a bearer independent protocol (BIP).

The entire system for backing up the information stored in the smart card to the backup server is composed of the smart card 100, the communication terminal 150 and the backup server 170.

The exchange of information between the smart card 100 and the communication terminal 150 according to an embodiment of the present invention may be performed by BIP or TCP / IP.

First, a case where information exchange is performed by BIP as shown in FIG. 1 will be described.

BIP uses the communication terminal 150 and a packet network (GPRS / UMTS packet bearer, Bluetooth, IrDA, etc.) supported by the network to perform data communication between the external node and the smart card 100 mounted on the communication terminal 150. This is a protocol to lose.

In order to perform data communication using the BIP, the communication terminal 150, the smart card 100, and the external node must all support the BIP.

Nodes supporting BIP should support CAT_TP (Card Application Toolkit_Transport Protocol) transport layer function, which includes connection management, reliable communication, flow control, and data segment management. (data segmentation management).

In order to perform packet communication using the BIP, a BIP channel is generated between the smart card 100 and the communication terminal 150, and a CAT_TP link is formed between the smart card 100 and the remote node. do.

An information backup request for backing up information stored in the smart card 100 according to an embodiment of the present invention is received from the communication terminal 150 and the information stored in the smart card 100 is transferred to the communication terminal 150. The process may be performed by the BIP. That is, the backup request from the communication terminal 150 to the smart card 100 may be performed by BIP commands, and information transfer from the smart card 100 to the communication terminal 150 may also be performed by BIP commands.

The communication terminal 150 only serves as a gateway for transmitting information stored in the smart card 100 to the backup server 170 located in the internet network.

In addition, since the input unit for receiving a command from the user does not exist in the smart card 100, the user may enter the smart card 100 from the user through an input unit (for example, a keypad or a touch pad) of the communication terminal 150. You can receive a backup request for the saved information.

The communication terminal 150 may be equipped with a smart card 100, the information can be exchanged by the smart card 100 and the BIP as described above. In addition, the communication terminal 150 may perform data communication with the backup server 170 located in the Internet network through TCP / IP.

In order to back up the information stored in the smart card 100 according to the present invention to the backup server 170 located in the Internet network, the communication terminal 150 may include a configuration that can be converted to transmit the protocol.

When the protocol for exchanging information between the communication terminal 150 and the smart card 100 is BIP, and the protocol for exchanging information with the backup server 170 located in the communication terminal 150 and the Internet network is TCP / IP, As shown in FIG. 1, the communication terminal 150 may include a BIP gateway and a TCP / IP protocol stack for exchanging information between the smart card 100 and the backup server 170.

This is to exchange information with the smart card 100 by the BIP and to change it in a TCP / IP manner so that it can communicate with the backup server 170.

Hereinafter, a case in which information exchange between the smart card 100 and the communication terminal 150 is performed by TCP / IP will be described.

In order for the smart card 100 to directly exchange information by TCP / IP, the TCP / IP protocol stack should be included in the smart card 100.

When performed by the BIP as shown in FIG. 1, the communication terminal 150 should include a configuration for protocol conversion for communication between the smart card 100 and the backup server 170, but the smart card 100 In case of direct exchange of information by TCP / IP, no protocol conversion is necessary.

In this case, the communication terminal 150 is located between the smart card 100 and the backup server 170 to perform only the role of the information transmitter.

The backup server 170 may be located in the Internet as a server that stores information stored in the smart card 100. If the backup server 170 is a device capable of directly communicating with the smart card 100 using the communication terminal 150 as a gateway, its type is irrelevant.

A process of storing the information stored in the smart card 100 in the backup server 170 via the communication terminal 150 will be described in more detail with reference to FIG. 3.

2 is a block diagram showing the configuration of a smart card equipped with a smart card web server (SCWS) according to an embodiment of the present invention.

2, the smart card 100 may include an interface unit 210, a storage unit 220, and a smart card web server (SCWS) 230.

The interface unit 210 receives the information backup request, and transmits the information stored in the smart card to the backup server 170 located in the Internet network.

An example of a method of transmitting information for backup to the backup server 170 may be transmitted via the communication terminal 150, and may be directly transmitted to the backup server 170.

First, a case in which the transmission is performed via the communication terminal 150 will be described.

According to an embodiment of the present invention, when the smart card web server 230 transmits information for backup to the backup server 170 via the communication terminal 150, the smart card web server 230 is a communication terminal ( 150) and a protocol, in which case the protocol to be set may be BIP.

Smart card web server 230 is a configuration located inside the smart card 100, a system that is responsible for the function to control the smart card 100 without the control of the communication terminal 150. The smart card web server 230 may be referred to as a kind of HTTP server implemented in the smart card 100.

The smart card web server 230 is a system capable of performing the role of a web server having a processor and a memory and may be utilized as a dual system capable of performing both a server and a client.

That is, the smart card web server 230 may serve as a server that actively performs work in response to a request of the communication terminal 150 in relation to the communication terminal 150, and may be a server located on the Internet network. In the present invention, the backup server 170 may serve as a client instructing the backup server to perform a specific task.

In addition, the smart card web server 230 receives a power supply from an external device such as the communication terminal 150, and is a device that actively performs a specific task, not a device that performs a dependent role in performing a specific task. Im already defined in the standard.

For example, the smart card web server 230 is a system in charge of smart card information, smart card life cycle, application protocol data unit (APDU) generation, subscriber management, and the like. Is a system that can request to open a BIP channel.

Hereinafter, a case in which the smart card web server 230 directly transmits backup information directly to the backup server 170 will be described.

The smart card web server 230 according to another embodiment of the present invention may control to directly communicate with the backup server 170 located in the Internet. For this purpose, the smart card web server 230 needs to set a protocol with the backup server 170. In this case, the protocol set is TCP / IP.

That is, the smart card web server 230 may be assigned an IP and exchange information with the backup server 170 through TCP / IP.

As such, the smart card web server 230 may establish a protocol with the communication terminal 150 or the backup server 170 in order to transmit the information read by the smart card web server 230 to the backup server 170.

The storage unit 220 performs a database function for storing information for backup. Due to the recent development of technology, it is possible to increase the capacity of a smart card, and as a result, the type of information that can be stored in the storage unit 220 is very diverse, and the amount that can be stored is also very large. An example of information that may be stored in the storage unit 220 of the smart card may be a still image, a video, a music file, or the like.

Information for backup according to an embodiment of the present invention may be phonebook information. If the phone book information is backed up, the user may download and use the phone book information backed up to the backup server even if the smart card 100 is lost later.

The information stored in the storage unit 220 may be variously changed in addition to the phone book information.

In FIG. 2, the smart card web server 230 and the interface unit 210 are illustrated as separate components, but it is obvious that the smart card web server 230 and the interface unit 210 may be implemented by one circuit. In addition, it is apparent that the smart card web server 230 may include volatile memory such as flash memory.

Also, although not shown in FIG. 2, when the smart card 100 exchanges information by TCP / IP, it is obvious that a TCP / IP protocol stack for this should be included in the smart card 100.

So far, the configuration of the smart card 100 according to the embodiment of the present invention has been described with reference to FIG. 2. Hereinafter, a process of backing up information stored in a smart card will be described with reference to FIG. 3.

3 is a flowchart illustrating a process of backing up information stored in a smart card to a backup server located in an internet network according to an embodiment of the present invention.

3 illustrates an example of receiving a backup request from the communication terminal 150, and it is apparent that a backup request may be received from a device other than the communication terminal 150.

First, the smart card web server 230 receives a request for backing up information stored in the smart card. The smart card web server 230 is a system having a function of controlling the configuration of the smart card 100 by itself without being controlled by the communication terminal 150 as described above.

However, since the smart card 100 does not have an input unit for receiving an input for performing a specific operation from the user, the smart card 100 receives a signal for performing a specific function from the user through the input unit of the communication terminal 150. In addition, the smart card web server 230 receives power from the communication terminal 150.

As described above, the information backup request from the communication terminal 150 may be performed by the BIP.

The smart card web server 230 receiving the information backup request controls to read the information stored in the smart card 100. The smart card web server 230 is implemented in the smart card and may read the information received from the storage unit from the storage 230.

For example, when the information received the backup request is phonebook information, the storage unit 220 may be a phonebook storage unit, and the storage unit 220 may be variously changed according to the type of information requested for backup. Self-explanatory

The smart card web server 230 may read the backup request information from the storage 220 and transmit the information to the backup server 170 or directly to the backup server 170 via the communication terminal 150.

In the present specification, via the communication terminal 150 means that information is not stored in a predetermined storage area (for example, a memory) of the communication terminal 150, and only the protocol is converted (when performed by BIP) to the Internet network. It is transmitted to the backup server 170 located.

The process of transferring the information read from the smart card web server 230 to the communication terminal 150 may be performed by any one protocol of BIP and TCP / IP, and the backup terminal located in the Internet network in the communication terminal 150. Information transmission to the server 170 may be performed via TCP / IP.

In particular, when information is transferred by the BIP between the communication terminal 150 and the smart card web server 230, the communication terminal 150 to communicate between the smart card web server 230 and the backup server 170. It just does the function of converting the protocol to do that. In this manner, the information received from the smart card web server 230 is transmitted to the backup server 170 through the Internet through the protocol conversion process in the communication terminal 150.

On the other hand, when information is transmitted by TCP / IP between the communication terminal 150 and the smart card web server 230, the communication terminal 150 transfers information between the smart card web server 230 and the backup server 170. It only serves as an intermediary bearer for exchange.

The backup server 170 may include a backup information receiver that receives information for backup through the Internet. The backup information receiver does not receive the information to be backed up from the communication terminal 150 but from the smart card web server 230.

The backup server 170 may include a database that stores information for backup.

In addition, the backup server 170 may include a transmitter that transmits a signal indicating that the backup is completed when the backup is completed. The transmitter of the backup server 170 may transmit a backup completion signal to the smart card web server 230.

The backup completion signal may also be transmitted to the smart card web server 230 via the communication terminal 150, where the backup completion signal passes through the communication terminal 150 in which the communication terminal 150 performs only one forwarder role. That is, the communication terminal 150 receiving the backup completion signal from the backup server 170 located in the Internet network means that only serves to deliver the received backup completion signal to the smart card web server 230. will be.

The backup information receiver and the transmitter of the backup server 170 may exchange data and signals with the communication terminal 150 through TCP / IP.

As such, when the information stored in the smart card is backed up by using the smart card in which the smart card web server is implemented, the memory of the communication terminal 150 is not used, thereby saving the memory of the communication terminal, and the communication terminal 150. In case of loss or change of), the information stored in the smart card can be easily backed up.

It will be described as performed in the smart card web server 230 in order to make it.

The smart card web server 230 receives a backup request (step S410). It is apparent that step S410 may be received from the communication terminal 150 and may be received from another device.

When a backup request is received from the communication terminal 150 according to an embodiment of the present invention, the reception of the backup request may be performed by any one of a protocol of BIP and TCP / IP, and when performed by the BIP, the communication terminal. The process of establishing a BIP channel between the 150 and the interface 210 of the smart card may be preceded.

Thereafter, the process proceeds to step S420 and the smart card web server 230 may control to read information corresponding to the backup request received in step S410.

The readable information according to an embodiment of the present invention may be phonebook information. In this case, the readable information may be read from a memory such as a phonebook storage unit in a smart card.

The smart card web server 230 performs a process of transferring the read information to the communication terminal (step S430). The delivery of the information read from the smart card web server 230 to the communication terminal is for delivery to the backup server 170 located in the internet network through the communication terminal 150.

That is, when the information read out from the smart card web server 230 directly to the backup server 170 located in the Internet network cannot be transmitted, the backup server after the protocol conversion (when performed by BIP) using the communication terminal 150 as a gateway 170).

Step S430 may be performed by any one of a protocol of BIP and TCP / IP, and when performed by BIP, the process of establishing a BIP channel between the communication terminal 150 and the interface 210 of the smart card may be performed in step S430. May be preceded previously.

When the smart card web server 230 directly transmits the read information to the backup server 170, the TCP / IP between the smart card web server 230 and the backup server 170 may be set as described above. .
