Description

  The present invention relates to a processing technique in an IC chip having a plurality of interfaces.

  IC cards are roughly classified into a type to which a UIM (User Identity Module) on which a contact type IC (Integrated Circuit) chip is mounted and a type to which a non-contact type IC chip is applied. An IC card to which a contact IC is applied is used for a credit card or a cash card, and is connected to an IC chip via a contact interface such as an IC card reader / writer device (an IC card is inserted into the device). Data is being read and written. The non-contact type IC card is used for some ID cards (for example, entry / exit management cards) and traffic cards (for example, SUICA (registered trademark)), and is a reader / writer device for non-contact type IC cards. The data is read from and written to the IC chip via.

  In recent years, in Japan, a non-contact communication coil (antenna) and a non-contact communication protocol or non-contact communication for communicating with a reader / writer device for a non-contact IC chip on a mobile phone equipped with a UIM. By incorporating a microcomputer for processing a contact application, various services using a non-contact interface are provided in addition to a UI (mobile phone service) of a contact interface. This mobile phone is equipped with a dedicated microcomputer for executing a contact application and a dedicated microcomputer for executing a non-contact application. Therefore, the mobile phone can simultaneously execute (function) a contact application and a non-contact application. Specifically, for example, the mobile phone simultaneously performs the incoming process to the mobile phone realized by executing the contact application and the gate passing process (entrance / exit management process) realized by executing the non-contact application. Is possible.

  On the other hand, mainly in Europe, the non-contact communication coil provided in mobile terminals equipped with UIM and the microcomputer mainly responsible for non-contact communication protocol processing are different from the existing contact interface provided in UIM. By connecting to an interface, a method for managing a contactless application in addition to a contact application within the UIM has been studied, and standardization of related technologies is being promoted. As one embodiment of this method, both the contact application and the non-contact application are stored in the UIM and share the hardware resources (CPU, storage device, various peripheral circuits) of the UIM. Are integrated and stored in a removable UIM, and there are advantages such as easy application management and migration (hereinafter referred to as NFC (Near Field Communication)).

  As mentioned earlier, the NFC method has advantages such as cost reduction effect and easy management and migration of applications by storing application for contact and non-contact in UIM. Because it is necessary to accept application processing requests asynchronously from contact / non-contact depending on the usage status of the user, etc., contention of processing requests cannot be avoided with 1 Chip.

  For such a situation, in Patent Document 1, in the case of an IC card having a plurality of interfaces, when command reception occurs at another interface during execution of a command received from one interface, command processing being executed is performed. A method has been proposed in which a command received asynchronously on a plurality of interfaces is received without being missed by interrupting and performing command reception processing.

  Patent Document 2 proposes a method in which a procedure composed of a plurality of commands is defined as a service, and priority processing is performed for each service. Furthermore, when service priority processing is started (when the first command processing that configures a service is started), after responding to the command processing result, the service is suspended by waiting for command reception for a certain period of time. There has also been proposed a method of giving priority to reception processing and command processing of the next command to reduce the switching overhead of service processing.

  By the way, when using a service that uses a non-contact interface, the user himself places the IC chip (IC card) on the reader (reader / writer device). It is desirable to complete the processing in a short time. In addition, in a traffic service to which a non-contact interface is applied, it is necessary to complete application processing within a certain short period of time in order for a user to pass an IC card to a reader when passing through a Gate (ticket gate or the like). There is. Reviewing Patent Document 1 in consideration of the characteristics of such a service using a non-contact interface, in order to efficiently receive a command sent to another interface during the received command processing. The effect of processing a service (for example, the entire clearing process by passing through the ticket gate) in a short time is limited. In other words, with the technique described in Patent Document 1, the entire service cannot be reliably processed in a short period of time.

  Moreover, in the technique described in Patent Document 2, in order to preferentially process a command constituting a service, the mobile terminal waits after a command response for a predetermined time. At this time, the portable terminal can communicate with the contactless reader. If you go out (you will no longer receive the next command), you may also be waiting as well, and if there is a waiting service due to low priority, you may not be able to quickly return to processing . In addition, in order to process the service as fast as possible, the method of performing the standby time management for receiving each command constituting the service for all commands was not efficient considering the time management overhead. .

[1. Overview of mobile terminal configuration and functions]
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The embodiment described below is an embodiment when the present invention is applied to a mobile terminal.

  First, with reference to FIG. 1, the configuration and functional overview of the mobile terminal according to the present embodiment will be described.

  FIG. 1 is a block diagram illustrating a schematic configuration example of a mobile terminal according to the present embodiment. As illustrated in FIG. 1, the mobile terminal 1 includes a controller 11, a CLF 12, a UIM 13, and the like that perform functions of the mobile terminal 1. Note that the mobile terminal 1 accesses a predetermined server by specifying, for example, operation keys, a display, a speaker, and a mobile communication unit (a general communication control function based on a W-CDMA or CDMA2000 communication method, URL). Mobile phone, PDA, and the like having a browser function for receiving predetermined information and a mailer function, etc.). In addition, since these functions in the terminal device 1 are well-known, detailed description is abbreviate | omitted.

  Although not shown, the controller 11 is a CPU (Central Processing Unit), a nonvolatile memory (such as a flash memory) that stores various programs and data, a RAM that temporarily stores data, and an I / O that serves as an interface with the UIM 13. It has a port. The controller 11 can communicate with the UIM 13 via an interface. And the controller 11 performs various processes according to the communication process (communication performed via a mobile communication network or the internet) of the portable terminal 1, and the operation instruction from the user of the portable terminal 1 via the operation key. In the course of such processing, the controller 11 performs, for example, communication processing (including incoming call processing) performed with the base station 3, services related to communication processing such as Web access and mail transmission / reception, other encryption processing and authentication. A command (signal) for executing a service such as processing (an example of a predetermined service of the present application) is transmitted to the UIM 13 via an interface (including a contact I / O port described later).

  In the present embodiment, a service (such as a service related to the communication process) that is executed based on command transmission / reception between the controller 11 and the UIM 13 is referred to as a contact service. A command for executing a contact service (for example, a data read command) is referred to as a contact command (see FIG. 1A). Note that transmission / reception of a contact command necessary for executing the contact service may be performed not only once but a plurality of times.

  The CLF 12 is a non-contact type IC chip that performs non-contact communication defined by the NFC standard (that is, adopts the NFC method), and although not shown, a CPU, a non-volatile memory that stores various programs and data, and data It includes a RAM for temporary storage, an I / O port (SWIO) that serves as an interface with the UIM 13, and the like. In CLF12 prescribed | regulated by this NFC specification, the communication system of FeliCa (trademark) is supported as Type-F in addition to the communication system of Type-A and Type-B. Such a CLF 12 is connected to an antenna 12a for transmitting and receiving various signals in accordance with the above communication method with the non-contact reader 2 in a non-contact field. When the user places the portable terminal 1 on the non-contact reader 2, the CLF 12 sends a command for executing a service (an example of a predetermined service of the present application) transmitted from the non-contact reader 2 to an interface (described later). (Including a non-contact I / O port).

  Examples of the services include prepaid cards and commuter passes for transportation facilities such as railways and buses, settlement services such as credit cards and electronic money, facility entrance / exit management, and the like.

  In the present embodiment, a service (such as the prepaid card described above) that is executed based on command transmission / reception between the CLF 12 and the contactless reader 2 is referred to as a contactless service. A command for executing the contactless service is referred to as a contactless command (see FIG. 1B). In addition, transmission / reception of the non-contact command necessary for executing the non-contact service may be performed not only once but a plurality of times.

  The UIM 13 is one of UICCs (Universal Integrated Circuit Cards), and is equipped with a contact IC chip whose functions are expanded based on a conventional SIM (Subscriber Identity Module). The UIM 13 includes a CPU (an example of a determination unit, a transition unit, and an end unit in the present embodiment), a nonvolatile memory that stores various programs and data (an example of a storage unit in the present embodiment), and a RAM that temporarily stores data. , Contact I / O ports responsible for the interface with the controller 11 (an example of a plurality of interfaces of the present application), non-contact I / O ports responsible for the interface with the CLF 12 (an example of the plurality of interfaces of the present application), etc. It has. Note that SWP (Single Wire Protocol) is applied to the interface between the CLF 12 and the UIM 13. Further, hereinafter, when the UIM 13 is simply described, it is assumed that the CPU of the UIM 13 is included.

  The program stored in the non-volatile memory of the UIM 13 includes an operating system (hereinafter referred to as “OS”) that controls the entire operation of the UIM 13 as well as a non-contact command received from the CLF 12. A contact interface application program (hereinafter referred to as “non-contact application”) and a contact interface application program (hereinafter referred to as “contact application”) for processing a contact command received from the controller 11 are implemented. In the mobile terminal 1 according to the present embodiment, the contactless service is executed by the control of the contactless app, and the contact service is executed by the control of the contact app.

  Furthermore, a start event table and a release event table are stored in the nonvolatile memory of the UIM 13.

  Here, the start event table and the release event table will be described with reference to FIG. FIG. 2 is a conceptual diagram showing a start event table and a release event table.

  As described above, since the UIM 13 executes the contact command and the non-contact command in the mobile terminal 1 according to the present embodiment, the UIM 13 may receive the contact command and the non-contact command asynchronously. In this case, as described above, when using the non-contact service, the user himself places the mobile terminal 1 (CLF 12) on the reader (non-contact reader 2). It is desirable that the processing related to the non-contact service be completed in as short a time as possible after being struck with the reader (that is, not interrupted or canceled).

  A specific case will be described as an example. For example, while a user makes a call using the mobile terminal 1 (during a call process as an example of a contact service), the user passes through a ticket gate of a transportation facility (an example of a non-contact service). The UIM 13 receives the non-contact command for executing the function of the commuter pass during the processing of the contact command for executing the call processing. In this case, if the UIM 13 ignores the process of the non-contact command newly received and continues the call process, the user cannot pass through the ticket gate, and the usability is significantly impaired.

  Therefore, in the present embodiment, in order to preferentially execute the service indicated by the received command, the start event table indicating the conditions for the UIM 13 to shift to the priority processing period for preferentially processing the command related to the service, A release event table, which is a condition for ending the priority processing period, is respectively defined and stored in the nonvolatile memory of the UIM 13. When the UIM 13 receives a command, the UIM 13 refers to the stored start event table to determine whether or not the stored start event is satisfied, and when it is determined that the command corresponds to the start event. The priority processing period is started, and when the condition corresponding to the release event table is detected during the priority processing period, the priority processing period is ended.

  Hereinafter, details of the start event table and the cancellation event table stored will be described.

  As shown in FIG. 2, in the start event table 131, as a start event, (a) UIM 13 recognizes a carrier wave for contactless communication (service priority using a contactless interface), (b) reception of a specific packet / frame. (Service priority using a specific protocol), (c) Command reception (service processing head command) constituting the service is stored.

  (A) UIM 13 explains the recognition of a carrier wave for non-contact communication. For example, when the portable terminal 1 enters the non-contact field, the UIM 13 receives a field-on signal from the non-contact reader 2 via the non-contact I / O port (SWP), and then the non-contact reader 2 A polling command signal (command for determining which communication method is used by UIM 13 among Type-A, Type-B, or FeliCa) is received. And UIM13 transmits the polling response signal which shows performing communication by Type-A, for example as a response with respect to a polling command signal. Then, the non-contact reader 2 transmits a command for executing the non-contact service to the UIM 13. When the UIM 13 in the present embodiment receives the field-on signal, the UIM 13 processes a command for executing a contactless service transmitted subsequently.

  (B) The specific packet / frame reception indicates, for example, a case where the UIM 13 detects that the communication protocol indicated by the carrier wave transmitted from the non-contact reader 2 is Type-A, Type-B, or FeliCa. In this case, the UIM 13 preferentially processes the non-contact command transmitted by the non-contact communication carrier wave.

  (C) Reception of a command constituting a service indicates a case where the UIM 13 receives a command for executing a specific service. In this case, the UIM 13 preferentially processes a command for executing a specific service transmitted by the non-contact communication carrier wave.

  In the cancellation event table 132, as the cancellation event, (d) the UIM 13 recognizes that the carrier wave for non-contact communication has been lost (goes out of the communicable distance), and (e) the predetermined number of commands is normal. (F) Normal termination of a predetermined command sequence, (g) Abnormal termination of a command response that constitutes a service, (h) A predetermined time T0 from the start of priority processing (period) by recognizing a carrier wave (I) A certain time T1 has elapsed since the priority processing was started by reception of a specific packet / frame, (j) a certain time T2 has elapsed since the priority processing was started by reception of a specific command, (k ) Reception of the explicit termination notification of service (application) session (ISO14443-4 DESELECT) is stored.

  (D) The UIM 13 recognizes that the carrier wave for non-contact communication has been lost indicates that the UIM 13 stops receiving the above-described field-on signal.

  (E) Normal termination of a predetermined number of commands will be described below. The above-described service is terminated when the UIM 13 processes a predetermined number of commands. The UIM 13 according to the present embodiment ends the priority processing period when all the commands necessary for ending the service are processed.

  (F) Normal end of a predetermined command sequence indicates that the UIM 13 ends the priority processing period when a plurality of predetermined command processing orders are normally executed.

  (G) Abnormal termination of a command response that constitutes a service indicates a case in which some abnormality has occurred and terminated while the UIM 13 is processing a command for executing the service. In this case, the UIM 13 ends the priority processing period.

  (H) The predetermined time T0 has elapsed since the priority processing was started by recognizing the carrier wave. For example, the UIM 13 receives the field-on signal and the priority processing period starts (the above (a)). When a predetermined time T0 (for example, 100 msec, etc.) has passed since the start of the priority processing period, it indicates that the priority processing period ends. As described above, when using the non-contact service, the user himself places the mobile terminal 1 on the non-contact reader 2 and moves the mobile terminal 1 away from the non-contact reader 2 when determining that the service has ended. However, depending on the user, it may be considered that the portable terminal 1 is left on the non-contact reader 2 (while it is placed). In this case, if the UIM 13 maintains the priority processing period in spite of the completion of the processing of the command for executing the service, the processing of the other command cannot be executed and the user usability is significantly impaired. It becomes. In order to solve such a problem, the UIM 13 ends the priority processing period when a predetermined time T0 has elapsed after the field-on signal is received and the priority processing period is started. Yes.

  (I) A certain time T1 has elapsed since the priority processing was started by receiving a specific packet / frame. For example, the communication protocol indicated by the carrier wave transmitted from the non-contact reader 2 by the UIM 13 is Type-A, After the UIM 13 detects that it is Type-B or FeliCa and shifts to the priority processing period (above (b)), when the predetermined time T1 has elapsed, it indicates that the priority processing period ends.

  (J) A certain time T2 has elapsed since the priority processing was started by receiving a specific command. For example, after the UIM 13 receives a command for executing a specific service and shifts to a priority processing period (see above). (C)) When the predetermined time T2 has elapsed, it indicates that the priority processing period is to end.

  (K) Reception of service session explicit end notification (ISO14443-4 DESELECT) means, for example, when UIM 13 receives an S (DESELECT) request as a service end notification transmitted from contactless reader 2. Indicates that the priority processing period ends.

  The values of T0, T1, and T2 can be arbitrarily set (for example, input from the outside). Further, the start event and the end event are not limited to the example described above, and can be set as appropriate.

[2. Operation of the mobile terminal 1 according to the first embodiment]
First, the operation of the mobile terminal 1 according to the first embodiment will be described with reference to FIG.

  FIG. 3 is a conceptual diagram illustrating the operation of the mobile terminal 1 according to the first embodiment.

  In the first embodiment, the user uses the mobile terminal 1 to make a call (during a call process as an example of a contact service) and pass through a ticket gate of a transportation facility (a commuter pass as an example of a non-contact service). This is a mode in which the UMI 13 receives a non-contact command during processing of a contact command. Further, in the first embodiment, when the UIM 13 receives a command for executing the function of the commuter pass as the service shown in the command reception of the c) service of the start event table 131, it shifts to the priority processing period. Is stored.

  In the example shown in FIG. 3, transmission of commands (including both non-contact commands and contact commands) from the contact IF (Interface, contact I / O port) and non-contact IF (non-contact I / O port) to the UIM 13 is performed. The response received from the S and UIM 13 to the contact IF and the non-contact IF is R. In addition, the period during which the command received by the UIM 13 under the control of the OS is crossed within the rectangular frame surrounded by the period during which the command received by the UIM 13 is controlled by the OS. In the range surrounded by the rectangular outer frame with the diagonal grid, the grid that intersects the period for processing the command received by the UIM 13 under the control of the non-contact application is represented by the range surrounded by the rectangular outer frame. The horizontal axis is the time axis. The priority processing period is T2.

  As shown in FIG. 3, when a contact command (command A) for executing the above-described call process is transmitted to the UIM 13 (S1), the UIM 13 performs a command reception process (S2), and then The contact command is processed under the control of the contact application (S3). In this case, the mobile terminal 1 is in communication with other mobile terminals.

  Next, when the user passes the ticket gate, a non-contact command (referred to as command B) is transmitted from the non-contact reader 2 to the portable terminal 1. Then, the UIM 13 receives a non-contact command (S4).

  The UIM 13 executes the command reception process so as not to lose the command (command A) transmitted on the non-contact IF regardless of whether or not the command process already received by the contact IF is performed (S5. Necessary). Whether or not the command A process that has been received and executed on the contact interface is interrupted) and the start event table 131 is referred to based on the received information on the command B to determine whether or not to shift to the priority processing period. Determine. Since the command B is a command for executing the function of the commuter pass, it corresponds to the condition (c) described above. Accordingly, the UIM 13 shifts to the priority processing period, interrupts the processing for the command A, and executes the processing for the command B (S6).

  If there is an interrupted command A process, the command A processing priority is compared with the received command B process priority. If the command A priority is high, the interrupted process is resumed and the command B If the priority of is high, the interruption may be maintained and the priority processing period (T2) of the service including the received command B may be started. The processing priority in this case can be arbitrarily set.

  And the process which transmits the process result of the command B is performed (S7), and a process result is transmitted to non-contact IF (S8). Further, the command B is transmitted to the UIM 13 to execute the function of the commuter pass (S9). The UIM 13 executes the command reception process (S10), executes the command process (S11), and transmits the processing result of the command B. The process is executed (S12), and the processing result is transmitted to the non-contact IF (S13).

  After that, when the commands constituting the service are processed correctly on the contactless IF, the user recognizes the end of the service processing by some action (opening the gate of the ticket gate, making a sound, etc.), and then the user The terminal 1 is moved out of the communicable distance of the non-contact reader 2. In this case, as a result of recognizing that the carrier terminal 1 has lost the carrier wave from the non-contact reader 2, the portable terminal 1 transmits a command notifying the UIM 13 that the CLF 12 has moved out of the communicable distance (S14).

  Then, the UIM 13 refers to the cancellation event table 132, detects the condition corresponding to (d) stored in the table, and ends the priority processing period.

  Then, the execution of the command A which has been interrupted is resumed (S15), the process of transmitting the process result of the command B is executed (S16), and the process result is transmitted to the non-contact IF (S17).

  In the IC card contact IF protocol, ISO 7816-03 (Part 3) standardizes a WTX (waiting time extension waiting time extension) response. This is because the UIM 13 always sends a WTX (waiting time extension) response when the command cannot be returned within a certain period of time after receiving a command from the IC card via the contact IF (controller 11). It is decided to return to. Specifically, when the UIM 13 receives the command, the UIM 13 starts a timer as part of the OS processing. After that, only when the UIM 13 continues command processing even after a certain period of time has elapsed, the OS interrupts command processing, and a specific character as the WTX is sent to the controller via the contact I / O. 11 is transmitted.

  This is used as an effective process for the terminal to detect a state in which the IC card interrupts the process for some reason and becomes unresponsive. That is, the terminal waits unconditionally for a certain period of time after transmitting the command. After that, when the request for extending the waiting time is not transmitted from the IC card, the terminal assumes that the IC card has runaway or stopped for some reason and cannot transmit a response.

  The UIM 13 in this embodiment (including the first example and the second example to be described later) conforms to the above-mentioned standard, and the UIM 13 may output a wait time extension request even within the priority processing period. it can. Therefore, the UIM 13 outputs a waiting time extension request while the UIM 13 shifts to the priority processing period, interrupts the processing for the contact command, and executes the processing for the non-contact command. The processing for the contact command can be suspended until the processing for the non-contact command is completed.

[3. Operation of the mobile terminal 1 according to the second embodiment]
Next, the operation of the mobile terminal 1 according to the second embodiment will be described with reference to FIG.

  FIG. 4 is a conceptual diagram illustrating the operation of the mobile terminal 1 according to the second embodiment.

  In the second embodiment, the mobile terminal 1 receives an incoming call (call processing as an example of a contact service) while passing through a ticket gate of a transportation facility (function of a commuter pass as an example of a contactless service). This is the form when there is a command). Further, in the second embodiment, when the UIM 13 receives a command for executing the function of the commuter pass as the service shown in the command reception of the c) service of the start event table 131, it shifts to the priority processing period. Is stored. Further, in the members and charts shown in FIG. 4, the same members and charts as those shown in FIG. 3 have at least the same functions and properties.

  As shown in FIG. 4, when the user passes the ticket gate, a non-contact command (referred to as command B) is transmitted from the non-contact reader 2 to the portable terminal 1. Then, the UIM 13 receives a non-contact command (S21).

  The UIM 13 executes command reception processing (S22), and refers to the start event table 131 based on the received information regarding the command B to determine whether or not to shift to the priority processing period. Since the command B is a command for executing the function of the commuter pass, it corresponds to the condition (c) described above. Accordingly, the UIM 13 shifts to the priority processing period, and executes the command B processing (S23).

  Next, when there is an incoming call to the mobile terminal 1 and a contact command is transmitted to the UIM 13 (S24), the UIM 13 executes command reception processing in order not to lose the command (command A) transmitted on the contact IF ( S25). Here, the start event table 131 does not include “the UIM 13 receives a contact command” as a condition for shifting to the priority processing period. Therefore, the UIM 13 continues the current priority processing period, and continues processing and transmission / reception of commands for executing call processing (S26 to S38).

  Then, when the UIM 13 receives a command for executing the function of the commuter pass and moves to the priority processing period and measures that a predetermined time T2 has elapsed, the UIM 13 refers to the cancellation event table 132 and stores it in the table. The condition corresponding to (j) is detected, and the priority processing period ends.

  Then, a command for executing the call process is processed (S39).

  In addition, when the command sequence of the service is variable, the command processing time constituting the service becomes considerably long in some situation (for example, reception status of the carrier wave), or some priority services exist and T2 By not setting the setting for each service, when T2 is the shortest constraint time, T2 with respect to the estimated processing time of the priority processing target service (the total processing time of all commands constituting the service) The setting time of may be short. In this case, since the non-contact command is transmitted again to the UIM 13, the UIM 13 shifts to the priority processing period to process the command and executes the processing (S40 to S44). ).

  When the command processing to be processed in the priority processing period is completed, the contact command processing is executed (S46), and the processing result is transmitted to the contact IF (S47, S48).

  In addition, embodiment described above does not limit the invention concerning a claim. And not all the combinations of the configurations described in the above embodiment are indispensable means for solving the problems of the invention.

  As described above, according to the present embodiment, when the UIM 13 receives a command, the UIM 13 refers to the start event table 131 to determine whether or not it corresponds to the start event, and is determined to correspond to the start event. In this case, since the priority processing period is terminated when the condition corresponding to the cancellation event table 132 is detected, the priority processing period is terminated. Can be processed.

  In the above embodiment, the case where the present application is applied to the UIM mounted on the mobile terminal 1 has been described as an example. However, it is possible to connect with other mobile terminals using a plurality of protocols (for example, USB) via the interface. The present invention can also be applied to other portable terminals that can perform communication.
