Description

  The present invention relates to a portable information storage medium, an information processing apparatus, and a program for establishing communication between the portable information storage medium and the information processing apparatus capable of performing communication using a plurality of different contactless communication methods. It relates to the establishment method.

The portable information storage medium receives a command (request) from an external terminal (information processing apparatus including a reader / writer) such as an ATM and transmits a response (response) to the command by contact-type or non-contact-type communication. Are communicating. A portable information storage medium is an IC card, a SIM card (Subscriber Identity Module), a UIM card (User Identity Module), an IC tag, a SIM card or a UIM card inserted into a mobile phone or a mobile holder, and an external device. A highly confidential portable information processing apparatus that includes a communication unit and an interface that mediate communication between a terminal and an IC, and that requires predetermined processing by an external terminal to access data inside the IC. . In order to perform communication between the portable information storage medium and the external terminal, it is assumed that it is determined which communication method is used for communication.
In the contact type, when an IC card is inserted into an external terminal, it is activated and sends an ATR (initial response). The ATR communication protocol is defined as T = 0 (protocol format) and 9600 bps (communication speed). Based on the capability of the IC card indicated by the ATR, the subsequent communication method is negotiated between the IC card and the external terminal. This is mainly determined from communication protocol options such as T = 0 / T = 1, 9600/19200/38400 bps, LSB / MSB (character bit arrangement order).

On the other hand, in the case of the non-contact type, the external terminal always emits radio waves, and only the IC card that has been able to receive radio waves above a certain level (with a certain level of power obtained from the antenna inside the card) is activated and is on standby It becomes a state. At that time, the external terminal also transmits a request request which is a communication target detection signal for detecting the communication target together with the radio wave. The IC card makes a response response to this request, thereby determining the communication method and establishing communication with the external terminal.
However, in the case of the non-contact type, in the Type-A method and Type-B method defined in ISO / IEC144443-3, REQA (Request Command, Type-A), REQB ( Request Command Type-B) is transmitted, however, since the radio wave propagation method is different, for example, as shown in FIG. 6, an IC card operating exclusively for the Type-A method cannot receive REQB. Therefore, the IC card operating exclusively for the Type-A method (Type-B method) receives REQA and returns ATQA (ATQB) as its initial response.
On the other hand, as an advanced IC card, an IC card compatible with both non-contact Type-A / B types, as shown in FIG. If reception is not possible correctly, it is necessary to try reception again or switch to Type-B to wait for reception, and there is a problem that a lot of time is spent on processing prior to establishment of communication such as trial.
Similarly, in an external terminal that performs non-contact communication corresponding to both systems, for example, as shown in FIG. 7B, by alternately transmitting radio waves of a system corresponding to Type-A and Type-B, An attempt is made to establish communication with an unknown contactless IC card (see, for example, Patent Document 1).
JP 2001-31699 A

  However, the Type-A method is an ASK (Amplitude Displacement Keying) 100% modified Miller (deformed mirror) method, whereas the Type-B method is an ASK 10% NRZ (Non-Return to Zero) method. Since the data received by the method that is not used cannot be obtained correctly, there is a problem that it takes time to establish a communication because the dark cloud has to wait for a request request.

FIG. 1 is a block diagram showing the configuration of a portable information storage medium according to the present invention, and the portable information storage medium in this embodiment is an IC card 10.
As shown in FIG. 1, the IC card 10 is guided to the external terminal 20 by being brought into the operating magnetic field of the external terminal 20 that is an information processing apparatus including a reader / writer that performs non-contact communication such as a gate terminal. It is a non-contact type IC card such as a proximity type or a proximity type that performs non-contact type communication by coupling. Further, the IC card 10 includes an IC chip 12 and an antenna 11 connected to the IC chip 12. The IC card 10 and the external terminal 20 are contactless with two types of communication methods, Type-A method and Type-B method. It is possible to perform communication.
The antenna 11 includes a resonance circuit having a winding coil and a tuning capacitor connected to both ends of the winding coil, and is connected to the interface 13 of the IC chip 12. The antenna 11 receives the electromagnetic wave transmitted from the external terminal 20 based on the electromagnetic induction method, converts the electromagnetic wave and the analog signal, such as converting the electromagnetic wave into an analog signal, and the electric power for the IC chip 12 to execute processing. It induces an electromotive force as energy and mediates communication between the external terminal 20 and the IC chip 12.

The IC chip 12 includes a CPU 14, an interface 13 connected to the CPU 14, a RAM 15, a ROM 16, and a nonvolatile memory 17.
The interface 13 includes a demodulation circuit that demodulates a modulation signal input from the antenna 11, a modulation circuit that modulates a signal output from the CPU 14, and the like, and is an interface that mediates input / output between the antenna 11 and the CPU 14. The interface 13 includes an A-type interface 131 and a B-type interface 132, a switching unit 133 connected to these interfaces, and the like. The A-type interface 131 and the B-type interface 132 are communication interfaces for communicating with the external terminal 20 by the Type-A method and the Type-B method, respectively, and perform modulation / demodulation, encoding, etc. according to the respective communication methods. A circuit serving as an interface corresponding to each communication method is provided. The switching unit 133 switches the connection between the A-type and B-type interfaces 131 and 132, the antenna 11, and the CPU 14 according to the control of the selection unit 141, and turns on one of the interfaces used for communication.

  The RAM 15 is a volatile memory and is used as a work area for the CPU 14 to perform processing. The ROM 16 is a nonvolatile read-only memory, and stores programs such as an operating system (OS) and an execution environment. The non-volatile memory 17 is a non-volatile rewritable memory such as an EEPROM, flash memory, or FRAM, and is normally used as a user work area, a program area, or the like. The nonvolatile memory 17 stores a communication method history. The communication method history was previously performed by the IC card 10 such as how many times the communication method of Type-A or Type-B was used previously, which communication method was used at the end of the previous communication, etc. This is information indicating a communication method history of communication.

The CPU 14 is a central processing unit that performs various operations, controls, and the like, and performs overall control of the IC card 10. The CPU 14 executes a program stored in a memory such as the ROM 16 and the nonvolatile memory 17, thereby executing the selection unit 141. The communication method determination unit 142 and the like are realized.
The selection unit 141 selects a communication method based on the communication method history stored in the nonvolatile memory 17. The communication method determination unit 142 determines whether or not the communication method selected by the selection unit 141 is appropriate. Details of the functions of the selection unit 141 and the communication method determination unit 142 will be described later with reference to FIG.

FIG. 2 is a flowchart showing the operation of the portable information storage medium according to the present invention, its program, and the communication establishment method. Hereinafter, the processing of the CPU 14 of the IC card 10 will be mainly described.
In step 110 (hereinafter, “step” is referred to as “S”), the IC card 10 enters the operating magnetic field region of the external terminal 20 such as being deceived by the external terminal 20 and supplies power from the external terminal 20. Receives and starts and starts processing. The selection unit 141 refers to the communication method history of the non-volatile memory 17 to acquire a frequently used communication method (Type-A method or Type-B method) (S120), and switches to the previous communication method by the switching unit 133. The corresponding interfaces 131 and 132 are switched on, and the IC card 10 is in a state of waiting for reception of a request request by a frequently used communication method (S130, S140, S160). The communication method determination unit 142 determines whether or not the communication method selected by the selection unit 141 is appropriate based on whether the request request is correctly received within a predetermined period (S150, S170). That is, when the communication method determination unit 142 has successfully received a request request within a predetermined period (when a REQA is received by the Type-A method, a REQB is received by the Type-B method), If it is determined to be affirmative and it cannot be received within a predetermined period, or if it cannot be demodulated or decoded even if received, it is determined as No. Note that the start of the predetermined period can be arbitrarily set, such as at the time of activation (S110).

When the communication method determination unit 142 determines NO (when the selected communication method is determined to be inappropriate), the selection unit 141 selects another communication method, that is, selects the Type-A method. If so, the Type-B method is selected. If the Type-B method is selected, the Type-A method is selected, the interfaces 131 and 132 are switched (S140, S160), and the request is normally made. The same processing is repeated until the request can be received or the power supply is cut off (S150, S170).
In S150 or S170, when the communication method determination unit 142 determines affirmative, the IC card 10 writes the communication method that has normally received the request request into the nonvolatile memory 17 as the communication method history (S180). The system enters a state of waiting for command reception, and the process for selecting the communication system is terminated (S190).

As described above, according to the present embodiment, the IC card 10 waits to receive a request request with a communication method that is frequently used, so that the probability that the external terminal 20 matches the communication method for transmitting the request request is improved. Thus, by reducing the number of trials, it is possible to efficiently establish communication with the external terminal 20 and increase the efficiency and speed of processing.
Further, the IC card 10 determines whether or not the selected communication method is appropriate, and selects another communication method when it is determined that the communication method is not appropriate. This makes it possible to increase the efficiency and speed of processing.

FIG. 3 is a block diagram showing the configuration of the information processing apparatus according to the present invention, and the information processing apparatus in this embodiment is the external terminal 20-2. In addition, the same code | symbol is attached | subjected to the part which fulfill | performs the same function as Example 1 mentioned above, and the overlapping description is abbreviate | omitted suitably.
The IC card 10-2 includes an IC chip and an antenna connected to the interface of the IC chip, and performs non-contact communication (Type-A method or Type-B method) with the external terminal 20-2. This is a typical non-contact IC card.
The external terminal 20-2 is an information processing apparatus such as a gate terminal that includes the R / W 21, the CPU 22, the storage unit 23, and the like, and processes information stored in the IC card 10-2. The R / W 21 is a reader / writer that realizes non-contact communication with the IC card 10-2, and performs non-contact communication using two types of communication methods, the Type-A method and the Type-B method. It is possible. The external terminal 20-2 uses one communication method to send a request request once and the other communication method to send a request request twice as one cycle. This cycle is repeatedly executed until it is detected (see FIG. 4 described later).

The R / W 21 includes a Type-A interface, a Type-B interface (not shown), a switching unit 211, and the like. The switching unit 211 has the same function as that of the switching unit 133 in the first embodiment, and switches interfaces corresponding to each communication method of the Type-A method and the Type-B method according to the control of the selection unit 221 of the CPU 22. It is a switching circuit to be performed.
The CPU 22 is a central processing unit that performs overall control of the external terminal 20-2, and implements a selection unit 221, a communication method determination unit 222, and the like by executing a program stored in the storage unit 23.
The selection unit 221 selects a communication method based on the communication method history stored in the storage unit 23. The communication method determination unit 222 determines whether or not the communication method selected by the selection unit 221 is appropriate. Details of the functions of the selection unit 221 and the communication method determination unit 222 will be described later with reference to FIG.

FIG. 4 is a flowchart illustrating an operation of an external terminal, a program thereof, and a communication probability method according to the present invention. Hereinafter, the processing of the CPU 22 of the external terminal 20-2 will be mainly described.
In S210, the selection unit 221 of the external terminal 20-2 refers to the communication method history in the storage unit 23, reads the communication method (Type-A method or Type-B method) in the previous communication, and the switching unit 211 uses the communication method history. The interface corresponding to the communication method is turned on, and the CPU 22 transmits a request request (REQA or REQB) and waits to receive a response (ATQA or ATQB) in this communication method (S220, S230, S290).
The communication method determination unit 222 determines whether or not the communication method selected by the selection unit 221 is appropriate based on whether or not a response is correctly received within a predetermined period. That is, the communication method determination unit 222 can normally receive a response (ATQA) while waiting to receive a response in the Type-A method within a predetermined period (when waiting for reception in the Type-B method). Is determined to be affirmative when ATQB is received. On the other hand, if the communication method determination unit 222 cannot receive a correct response within a predetermined period, for example, if it is not received, or if it cannot be demodulated or decoded because the communication method is different even if it is received, the communication method determining unit 222 (S240, S300).

When the communication method determination unit 222 determines NO in S240 or S300, the external terminal 20-2 repeats the same processing as S230 and S240 (or S290 and S300) (S250, S260 or S310 and S320). . In S260 or S310, when the communication method determination unit 222 determines again that the communication method determination unit 222 determines NO, the selection unit 221 selects another communication method, that is, if the Type-A method is selected, the Type- If the B method has been selected and the Type-B method has been selected, the Type-A method is selected, the interface is switched by the switching unit 211, the request request is transmitted, and a response reception wait state is established ( S270, S330).
The external terminal 20-2 repeats the same process until it receives a response normally (S280, S230, S340, S290).
In S240, S260, S280, S300, S320, or S340, when the communication method determination unit 222 determines positive, the external terminal 20-2 stores the communication method that has received the response normally as the communication method history. (S350), the processing for selecting the communication method is terminated (S360), and communication between the external terminal 20-2 and the IC card 10-2 detected as a communication target is established by this communication method.

As described above, according to the present embodiment, the external terminal 20-2 transmits a request request according to the previously used communication method at a higher rate than other communication methods. It is possible to increase the probability of matching with the communication method waiting for reception, efficiently detect the IC card 10-2 to be communicated, establish communication, and increase the efficiency and speed of processing. became.
In addition, the external terminal 20-2 determines whether or not the selected communication method is appropriate, and selects the communication method again when the external terminal 20-2 determines that the communication method is appropriate. 2, and it is possible to increase the efficiency and speed of processing.
