Description

  The present invention relates to a data processing method performed between a portable terminal having a short-range wireless communication interface and a reader / writer, and a portable terminal and reader / writer suitable for the data processing method, for example, music via a reader / writer connected to a network. The present invention relates to a technique effective for application to data processing such as distribution and ticket reservation.

  One of the short-range wireless communication interfaces is a short-range wireless communication standard called NFC (Near Field Communication), which is an international standard as ISO / IEC IS 18092. It uses 13.56MHz radio waves and enables two-way communication of 100 to 400kbps at a very short distance of about 10cm. It is a portable device such as a non-contact IC card, mobile phone, and PDA (Personal Data Assistant). Widely applied to terminals.

  The short-range wireless communication interface is used for payment for purchasing goods, automatic ticket gates for transportation, and the like. The former settlement process is completed with one reader / writer. In the latter automatic ticket gate, the bidding process is completed with one reader / writer, and the bidding process is completed with another reader / writer. In the billing process, information recorded on the mobile terminal in the bid process is used. When each of the settlement processing, bidding processing, and billing processing is performed, the mobile terminal must be within the communication range of the reader / writer, and if the mobile terminal goes out of service on the way, the processing is stopped and the processing can be restarted from the beginning. I need it. In any case, when data processing is performed by placing a mobile terminal within the communication range of one reader / writer, the owner does not operate the mobile terminal and participate in the data processing.

  As a data processing system using short-range wireless communication, for example, the one described in Patent Document 1 holds an IC card over an external reader / writer so that the IC card starts communicating with the reader / writer through a wireless interface. The IC card gives a change in its internal state to a host device or the like, and describes that the host device controls activation of a specific application or performs power supply control.

  When the inventor pays attention to one application in the data processing using the short-range wireless communication, after starting the processing by placing the mobile terminal in the communication area of the reader / writer (carrier on), We examined how to continue the process by turning the carrier on again without interrupting the process by putting it out of the communication range of the reader / writer (carrier off). For example, when downloading desired music using a reader / writer connected to a music distribution network, the menu program is stored in the mobile terminal by performing secure authentication such as user authentication with the music distribution company at the first carrier-on. After downloading, perform the menu operation with the carrier turned off, then turn on the carrier again, send the selected song etc. from the reader / writer to the music distribution company, download the desired song, and finally complete the settlement. It is a process like this. However, there has been no conventional technique represented by Patent Document 1 regarding a technique that takes such processing into consideration. According to the inventor's study, a method for completing one data processing by repeating such carrier-on multiple times is such that the reader / writer is separated from other portable terminals when the carrier is off during the processing. Therefore, it is necessary to consider this point in order to continue the interrupted processing. Furthermore, when the process is complicated, a mechanism is required to ensure consistency between the interrupted process and the continued process. If the interruption period is too long, one reader / writer must control many application processes, and the scale of computer resources increases undesirably.

  An object of the present invention is to perform a process of starting a process by turning on a mobile terminal and then continuing the process by turning on the carrier again without interrupting the process even if the mobile terminal is turned off. To provide a data processing method suitable for the above.

  A more specific object of the present invention is to start another process with another portable terminal when the carrier is turned off in the middle of processing when the carrier on is repeated a plurality of times to complete one data processing. It is an object of the present invention to provide a data processing method that can easily guarantee the continuation of the interrupted processing.

  Still another specific object of the present invention is to easily achieve consistency between a suspended process and a continued process when the process of completing one data process by repeating carrier-on multiple times is complicated. An object of the present invention is to provide a data processing method.

  Still another specific object of the present invention is to allow data to be interrupted in a case where one data processing is completed by repeating carrier-on multiple times so that the scale of computer resources is not undesirably increased. It is to provide a processing method.

  Still another specific object of the present invention is to prevent the possibility of data being tampered with in a portable terminal during a processing interruption period when one data processing is completed by repeating carrier-on multiple times. To provide a data processing method.

  Another object of the present invention is to provide a portable terminal suitable for the data processing method.

  Still another object of the present invention is to provide a reader / writer suitable for the data processing method.

  The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

  The following is a brief description of an outline of typical inventions disclosed in the present application.

  That is, in the data processing method according to the present invention, the reader / writer recognizes the terminal ID of the portable terminal within the communicable range by the short-range wireless communication interface, and the reader / writer requests the recognized portable terminal to request program processing. The reader / writer performs control for re-establishing communication with the portable terminal using a terminal ID collation match with the portable terminal once unable to communicate as a first condition. Since communication for resuming the interruption process is re-established on the condition that the terminal ID is matched, it is easy to guarantee the continuation of the interrupted process even if another portable terminal interrupts the reader / writer when the carrier is off. .

  The reader / writer manages the execution stage of the program processing by the portable terminal with the value of the processing state, and in the restart process, a value that matches the value of the processing state managed by the reader / writer is notified from the portable terminal. Control to re-establish communication on condition of. When the process of completing one data process by repeating the carrier-on multiple times is complicated, it is possible to easily achieve the consistency between the interrupted process and the continued process. Even if processing is not complicated, by managing the processing state, it is easy to distinguish whether it is the terminal ID of a mobile terminal that has entered the communication range for the first time or the terminal ID of a mobile terminal that has entered the communication range again during processing can do.

  When there is no response from the portable terminal having the terminal ID recognized by the reader / writer for a certain time, the reader / writer performs a timeout process for discarding the recognized terminal ID. Thereby, it is not necessary to unnecessarily increase the scale of computer resources, and it is possible to prevent the possibility of data being tampered with in the portable terminal during the carrier-off.

  The effects obtained by the representative ones of the inventions disclosed in the present application will be briefly described as follows.

<Outline of short-range wireless communication interface>
In data processing using short-range wireless communication between the reader / writer 2 and the portable terminal 1, focusing on one application, the processing is started by placing the portable terminal 1 within the communication range of the reader / writer 2 (carrier on). Then, even if the portable terminal 1 is once moved out of the communication range of the reader / writer 2 (carrier off), the processing can be continued by turning on the carrier again without interrupting the one application process. . For this purpose, the short-range wireless communication interface control includes a terminal ID management function, a processing state management function, a timeout processing function, and the like as features.

  With the terminal ID management function, when the reader / writer 2 first recognizes the terminal ID of the portable terminal 1 within the communicable range, the reader / writer 2 requests the recognized portable terminal 1 for program processing, and once communication is disabled ( The reader / writer 2 performs control to re-establish communication with the portable terminal 1 on the condition that the terminal ID collation coincides with the portable terminal 1 that has been temporarily suspended. is there. Since communication for resuming the interruption process is re-established on the condition that the terminal ID is matched, it is easy to guarantee the continuation of the interrupted process even if another portable terminal interrupts the reader / writer when the carrier is off. .

  The processing state management function means that the reader / writer 2 manages the value of the processing state corresponding to the execution stage of the program processing by the portable terminal 1 and is managed by the reader / writer 2 when the interrupted processing is resumed. The reader / writer 2 performs control for re-establishing communication with the portable terminal 1 under another condition that a value matching the value of the processing state is notified from the portable terminal 1. is there. Thereby, it is possible to easily achieve consistency between the interrupted process and the continued process when the process of completing one data process by repeating the carrier-on multiple times is complicated. Even if processing is not complicated, by managing the processing state, it is easy to determine whether it is the terminal ID of the mobile terminal 1 that has entered the communication range for the first time or the terminal ID of the mobile terminal 1 that has entered the communication range again during the processing. Can be distinguished.

  The time-out processing function is such that when there is no response from the portable terminal 1 of the terminal ID recognized by the reader / writer 2 for a certain time, the reader / writer 2 performs a timer counter process for discarding the recognized terminal ID. Thereby, it is not necessary to unnecessarily increase the scale of computer resources, and it is possible to prevent the possibility of data being tampered with in the portable terminal during the carrier-off.

As for the program processing by the portable terminal 1, the progress of the processing is managed by the processing state. The management is performed by both the portable terminal 1 and the reader / writer 2. Here, one application process is managed by process state 1 to process state N for convenience. N is an arbitrary number from 2 to N.

In the processing state 1, the program is downloaded from the reader / writer 2 to the portable terminal 1 and the downloaded program is stored in the ROM 311 or the RAM 313 in the communication area (P3). Thereafter, the processing result is communicated from the portable terminal 1 to the reader / writer 2, and the processing state number is updated to the next value (105). On the portable terminal 1 side, the processing state number is updated by performing processing for transmitting the processing result, and on the reader / writer side, the processing state number is updated by receiving the processing result. The process proceeds sequentially according to the update of the process state number. In the branch process (102) depending on the processing status, when the portable terminal 1 transitions to the area again (P2, P3), the processing state number given from the reader / writer 2 and the processing state number managed by the portable terminal 1 itself are The process proceeds to the process state number on the condition of the match.

  In processing state 2 and later, processing of command communication / command execution (107, 111) and result communication (109, 113) is performed in the same manner as described above. Although omitted in the processing state 1 to simplify the explanation, in the processing state 2 and later, even if the mobile terminal 1 goes out of service area after command communication / command execution (107, 111) or during command execution, application processing is performed. When the mobile terminal 1 enters the area again and is turned on (110, 114), the command execution result of the processing state can be transmitted from the mobile terminal 1 to the reader / writer 2, and the processing state number is also the next. (109, 113), and it is possible to continue processing in the subsequent processing state.

  Each time the processing of the processing state is completed, it is determined whether the processing of the last processing state number is completed (115). If the processing of the last processing state number is not completed, it is determined whether carrier-off has occurred (116). If the carrier is not off, the process returns to step 102. If the carrier is off, the process returns to step 101. If the process of the last process state number has been completed, the carrier is turned off by moving out of the service area (117), and the application process is terminated (118). The timer counter operation for timeout processing is started after command transmission of the command communication / command execution processing 107 and 111 in each processing state, for example, and at the end of the result communication processing state represented by 105, 109 and 114 It may be activated as the process. If the timer counter operation does not time out, the flow in FIG. 2 is continued until the last processing state. However, once the time-out occurs, the reader / writer 2 discards the terminal ID related to the time-out, thereby interrupting the application process. It becomes impossible to continue, and it is necessary to restart the application process from the beginning.

《Detailed processing procedure of data processing method》
4 associates the control of the reader / writer (RDWR) 2, the short-range wireless communication control chip (NFFCHP) 3, and the host device (HST) 4 in the processing of the processing state 1 (corresponding to FIGS. 110 and 105). FIG. 5 shows the control of the reader / writer (RDWR) 2, the short-range wireless communication control chip (NFFCHP) 3, and the host device (HST) 4 in the processing of the processing state N (corresponding to 107 to 114 in FIG. 1). Shown in association with each other. In each figure, processing steps by the reader / writer (RDWR) 2 are given reference numbers in the 200s, processing steps by the short-range wireless communication control chip (NFFCHP) 3 are given reference symbols in the 300s, and the host device ( The processing steps according to HST) 4 are given reference numerals in the 400s.

  In FIG. 4, the HST 4 supplies battery power (420), performs initial setting to NFCCHP3 (421), and transitions to reception waiting (422). The NFCCHP 3 is activated upon receiving battery power (330), and after initial setting, transitions to reception waiting (331). The RDEWR2 transmits a polling command at an appropriate timing (210, 211). If the mobile terminal 1 is in the communication range, the NFCCH3 receives the polling command (332), and the RDWR2 appropriately authenticates the user to the NFCCH3. A secure authentication process is performed (212, 333). This is because it is assumed that payment is made via a financial institution, copyright data is downloaded, confidential data is downloaded, and the like. After the authentication process (212), the RDWR 2 transitions to a reception waiting state (213). During this time, NFCCHP3 generates a chip ID as a terminal ID using unique data in ROM 311 and EEPROM 314, holds the generated chip ID in RAM 312 (334), and transmits the generated chip ID to RDWR2 ( 335), transition to the reception waiting state (336).

  The RDWR 2 that has received the chip ID collates with the chip ID already registered in the internal RAM (not shown) (214), and if it is a new ID, registers the chip ID in the internal RAM (not shown) ( 215), a storage area for storing and managing the processing state number of the new chip ID is secured in the internal RAM (not shown) (216), and the processing state number in the area is set to the initial value (217). . Then, the RDWR 2 transmits an application program for controlling the processing from the processing state 1 to the processing state N to the NFCCHP 3 (218), and transitions to reception waiting (219).

  The NFCCHP 3 receives the program transmitted at step 218 and stores it in the RAM 313 (337). Of the program stored in the RAM 313, the part executed by the HST4 is transmitted to the HST4 (338), and a storage area for storing and managing the process state number in the RAM 313 is secured (339), and the process state number in the area is stored. Is set to an initial value (340). At this stage, the RAM 313 of the NFCCH3 holds a generated chip ID, a processing state number, and a program that defines the application, as illustrated in FIG. The storage area of the processing state number may be allocated to the SYSREG 310. In addition, the ROM 311 and the EEPROM 314 hold chip specific values used for generating a chip ID.

  The HST 4 receives the program transmitted in step 338 and stores it in the RAM 402 or the like (423), notifies the NFCCHP 3 that the stored program is ready for execution (424), and transitions to reception waiting (425).

  When NFCCHP3 receives a notice of completion of program execution preparation from HST4 (341), it outputs a processing state 1 completion signal to RDWR2 (342), updates the processing state number on RAM 313 to +1 (343), and waits for reception. (344).

  When RDWR2 receives the processing state 1 completion signal (220), it updates the processing state number in the internal RAM (not shown) to +1 (221).

  Although not particularly limited, in FIG. 4 and FIG. 5, after processing state 1 in FIG. 4 ends, even if mobile terminal 1 goes out of the communication area of reader / writer 2 and then enters the service area, it enters processing state 2. It is supposed to be connected. In other words, in FIG. 5, the RDWR 2 transmits a polling command (230), and repeats an operation (231) for transitioning to waiting for reception at a required timing. If PDA1 is within the communication range of RDWR2, NFCCH3 receives the polling command (350), transmits the chip ID held in RAM 313 to RDWR2 (351), and transitions to reception waiting (352). When the RDWR2 receives the chip ID, the RDWR2 collates it with the chip ID held in its own internal RAM (232), and when the collation matches, acquires the processing state number corresponding to the chip ID from the internal RAM (233). The transmitted chip ID and command are transmitted to NFCCHP 3 (234), and timeout processing is performed (235). If the collation does not match in step 232, an error code is returned to NFCCHP3 although not shown.

  In the timeout process (235), the reader / writer 2 sets a predetermined time in the timer 201, and then waits for a response until a timeout occurs (236). The process 236 for waiting for a response is a process for performing a chip ID collation and a process state transmission when there is a response after transmitting a polling command, and is the same as the process from step 230 to step 234. If there is no response until time-out, for example, by time-out interrupt processing, the chip ID and processing state information targeted for the application related to time-out are discarded, and the application processing is stopped. When the RDWR 2 is performing the process 236, the NFCCHP 3 may go out of the communication range of the RDWR 2.

  When RDWR2 waits for a response in step 236, it receives the processing state information and command from RDWR2 (353). NFCCHP3 collates the processing state held in RAM 313 with the processing state received this time (354). A match or mismatch is determined (354). If they match, NFCCHP3 sends a command to HST4 (356). The HST 4 receives the command (430), executes the command if the received command is not a processing end command (432), transmits the command execution result to the NFCCHP 3 (433), and shifts to reception waiting (434). If it is determined in step 431 that the command is a process end command, the HST 4 discards the program of the application (435) and returns the result to the NFCCHP 3 (436, 365).

  When NFCCHP3 receives the command execution result from HST4 (357), processing 358 is performed in response to the processing of step 236 by the RDWR2. When performing the processing in step 358, NFCCHP3 only needs to be within the communication range of RDWR2. The process of step 358 is a process of transmitting a chip ID to the RDWR2, receiving a process state returned in response thereto, and determining whether or not the received process state matches the process state held in the RAM 313. Thru | or the process to step 355 is the same. When the processing state received in step 358 matches the processing state held in the RAM 313, the transmission result is returned to the RDWR2, and the processing state is updated by one (360), thereby completing the processing of all the processing states of the application. If not, a transition is made to waiting for reception, timeout processing is performed (362), and a polling command is transmitted from RDWR2 (350). The time-out process (362) by NFCCHP3 is a process in which the CPU 308 sets a predetermined time in the TMR 312 and starts a timer operation. If the time-out process occurs until the polling command is transmitted (350), the time-out process (362) The current chip ID and processing state information are discarded, the program of the application is discarded by the HST 4, and the processing of the application is stopped. Even when the determination in step 355 is not coincident, the chip ID and processing state information held in the RAM 313 are discarded, the program of the application is discarded in the HST 4, and the processing of the application is stopped.

  When RDWR2 receives the command execution result from NFCCHP3 (237), it determines the processing result (238), and if it is normal, it updates the processing state by +1 (239). The application-execution target chip ID being processed is discarded (242), and if it is not completed in step 240, the same timeout process (241) is performed so that processing for the next processing state can be continued. Is done. After this timeout process (241), RDWR2 enters the process of step 230. At this time, NFCCHP3 may be out of the communication range of RDWR2. As described above, if NFCCH3 enters the communication range of RRDWR2 before timeout, NFCCHP3 and RRDWR2 can continue processing in response to the polling command (350).

  In the data processing procedure described with reference to FIG. 5, the time-out by the TMR 312 is notified as an interrupt request to the INTC 306 by the signal TMOUT, whereby the CPU 308 is requested to interrupt by the signal INT, and the CPU 308 responds to the interrupt factor. The interrupt processing program is executed to perform the processing in the case of the time-out described above.

  In addition, the transition from the reception waiting transition state to the next control is performed by the CPU 308 executing the interrupt processing program corresponding to the interrupt factor by notifying the INTC 306 of the completion of communication by the signal COMCMP as an interrupt request. Is called.

  In the data processing procedure of FIGS. 4 and 5, the terminal ID management function is configured such that, for example, when the PDA 1 enters the area from outside the communication area of the RDWR 2, the chip between the RDWR 2 and the PDA 1 that previously recognizes the chip ID. This is realized by performing control for re-establishing communication with the PDA 1 under the condition that ID collation coincides as one condition (232, 234).

  In the data processing procedure of FIGS. 4 and 5, the processing state management function manages the value of the processing state corresponding to the execution stage of the program processing by the PDA 1, and the RDWR 2 manages when the interrupted processing is resumed. This is realized by controlling the RDWR 2 to re-establish communication with the PDA 1 (233, 234) on the condition that the value matching the value of the processing state is notified from the PDA 1.

  In the data processing procedure of FIGS. 4 and 5, the timeout processing function is for the reader / writer 2 to discard the recognized terminal ID when there is no response from the portable terminal 1 of the terminal ID recognized by the reader / writer 2 for a certain period of time. This is realized by the timer counter process (235). In FIG. 5, the PDA 1 also performs a timeout process (362).

Of course. At this time, in order to determine whether or not to permit the continuation of the processing, steps 230 to 234 in FIG. 5 are inserted after step 219 in FIG. 4, and steps 350 to 354 in FIG. 5 are inserted after step 341 in FIG. Is inserted, and if the comparison result of the inserted step 354 matches, the step 342 is made possible, and if they do not match, the chip ID, processing state number and program are discarded and the processing is stopped.
