  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a communication terminal and a communication control terminal, a program, and a communication method according to an embodiment of the invention will be described in detail with reference to the accompanying drawings.

(Embodiment 1)
FIG. 1 is a diagram showing an example of a configuration of a communication system configured by arranging communication terminals according to an embodiment of the present invention.

  The communication control station 40 functions as a communication control terminal that controls communication when communicating with the communication terminal 10. Here, the communication control station 40 and the communication terminal 10 have a plurality of (Near Field Communication: NFC) interfaces with each other (two in this embodiment), and perform data communication using these interfaces. . In some cases, the communication control station 40 supplies power to the communication terminal 10. This is performed using a proximity non-contact communication interface having a power feeding function by electromagnetic induction.

  FIG. 2 is a diagram illustrating an example of the configuration of the communication terminal 10 illustrated in FIG.

  The communication terminal 10 includes a control unit 11, a storage unit 12, a first communication unit 13, a second communication unit 14, a power management unit 15, and a power supply unit 16.

  The control unit 11 includes, for example, a CPU (Central Processing Unit) and the like, and performs overall control (for example, communication control) for the entire communication terminal 10. The storage unit 12 is composed of, for example, a memory and stores programs and data. The first communication unit 13 is a proximity non-contact communication interface that includes, for example, an RFID (Radio Frequency Identification) reader / writer and the like and has a power feeding function by electromagnetic induction. The second communication unit 14 is a proximity non-contact communication interface that adopts a communication method different from that of the first communication unit 13. The second communication unit 14 may be a communication interface having a higher communication capability than the first communication unit 13 (satisfying at least one of high-capacity data communication and high-speed data communication). For example, a communication method such as USB (Universal Serial Bus) may be used.

  The power management unit 15 also manages monitoring of the remaining amount of power and power output. The power supply unit 16 supplies power to each block through the power management unit 15. The power management unit 15 switches power between power from the power supply unit 16 and power supplied from another terminal (for example, a communication partner terminal) using the first communication unit 13 to supply power to each block. .

  The above is an explanation of an example of the configuration of the communication terminal 10, but the communication terminal 10 is not limited to the above-described configuration, and is configured by adding functions such as a storage device, an input device, and an output device as necessary. May be. In addition, although description is abbreviate | omitted in this embodiment, the communication control station 40 also takes the structure similar to the communication terminal 10 mentioned above.

  Here, the first communication unit 13 and the second communication unit 14 illustrated in FIG. 2 will be described with reference to FIG.

  Reference numerals 20 and 30 denote MACs (Medium Access Controllers) that manage the media access layer. Reference numerals 21 and 31 denote BBPs (Base Band Processors) having communication signal processing functions such as error correction coding, decoding, and modulation / demodulation. Reference numerals 22 and 32 denote RF (Radio Frequency) blocks for processing baseband signals in the carrier frequency band. Reference numerals 23 and 33 denote antennas for transmitting and receiving a modulated signal in a carrier frequency band in a wireless section.

  The first communication unit 13 operates with power supplied by electromagnetic induction from the outside (for example, the communication control station 40) or power supplied from its own device (power supply unit 16). Electromagnetic induction is performed using the antenna 23. Note that when operating with only power supplied by electromagnetic induction, a reduction in communication speed is expected, and in some cases, operation may be performed using power supplied from the device itself. Further, the first communication unit 13 has a power switch 24 whose power supply output is managed by the MAC 20. In the first communication unit 13, the prevention of reverse current is managed by a reverse current prevention circuit (not shown). This management is performed by a command received by the MAC 20 and the power switch 24.

  Next, an example of the operation in the communication terminal 10 shown in FIG. 1 will be described with reference to FIG. Here, a case where the communication terminal 10 communicates with the communication control station 40 (communication partner terminal) will be described.

  The first communication unit 13 of the communication terminal 10 is activated by power supply by electromagnetic induction from the communication control station 40. Then, the communication terminal 10 connects with the communication control station 40 using the 1st communication part 13 (S100). The communication terminal 10 exchanges communication data amounts with the communication control station 40 connected using the first communication unit 13 (S101). The exchange of the communication data amount is performed using the second communication unit 14. Whether the communication data is upstream or downstream to the communication control station 40 is arbitrary.

  The communication terminal 10 notifies the power management unit 15 of the communication data amount and the like in the control unit 11. Receiving this, the power management unit 15 calculates and predicts the amount of power required for communication based on the amount of communication data (S102). Then, the power management unit 15 sets the predicted power amount as a predetermined value, and compares the predetermined value with the remaining power of the power supply unit 16. As a result, the power management unit 15 determines whether or not the remaining power of the power supply unit 16 is sufficient (S103).

  As a result, if the remaining amount of power is sufficient (YES in S103), the control unit 11 performs data communication using the second communication unit 14 (S104). If the data communication is completed (YES in S109), the control unit 11 determines whether or not the power supply using the first communication unit 13 is received from the communication control station 40. If power supply is received (YES in S110), a power supply stop request is made. That is, the power supply stop is notified to the communication control station 40 via the first communication unit 13 (S111). Thereafter, this process is terminated. If the power supply is not received (NO in S110), this process is terminated as it is.

  On the other hand, if the remaining power is not sufficient as a result of the determination in S103 (NO in S103), the control unit 11 has already received power supply from the communication control station 40 using the first communication unit 13. Determine. If power supply has already been received (YES in S105), the control unit 11 requests the communication control station 40 to supply further power (S107). On the other hand, if power supply is not received (NO in S105), the control unit 11 requests the communication control station 40 to supply power using the first communication unit 13 (S106). In response to this request, the communication terminal 10 receives power supply from the communication control station 40 using the first communication unit 13 (S108). Thereafter, the communication terminal 10 returns to the process of S103 again.

  Here, an example of the flow of processing when the communication terminal 10 shown in FIG. 1 performs data communication with the communication control station 40 will be described with reference to FIG.

  The communication control station 40 first activates its first communication unit in order to communicate with the first communication unit 13 of the communication terminal 10 (S200). Thereby, electric power is supplied to the 1st communication part 13 of communication terminal 10 by electromagnetic induction (S201). At this time, the first communication unit 13 of the communication terminal 10 is activated as a storage (S202). The first communication unit 13 of the communication terminal 10 returns a response indicating that it has been activated as a storage to the communication control station 40, and establishes a connection with the communication control station 40 (S203).

  Here, the first communication unit 13 of the communication terminal 10 requests the second communication unit 14 to start up, and notifies the control unit 11 that it is starting up as a storage (S204). In response to this activation request, the second communication unit 14 in the communication terminal 10 is activated (S205). Subsequently, the communication control station 40 activates its own second communication unit (S206). Thereafter, the communication data amount is exchanged between the communication terminal 10 and the communication control station 40 (S207).

  Here, it is assumed that the communication terminal 10 does not have enough power to perform data communication corresponding to the exchanged communication data amount. In this case, the communication terminal 10 requests the communication control station 40 to supply power for performing data communication in the control unit 11 (S208). In response to this request, power supply to the communication terminal 10 via the first communication unit 13 is started. Then, the communication terminal 10 starts data communication with the communication control station 40 using the power (S209). When this data communication is completed, the communication terminal 10 requests the communication control station 40 to stop power supply (S210).

  Next, an example of the flow of power supply processing in S208 shown in FIG. 5 will be described with reference to FIG.

  In the power management unit 15, the communication terminal 10 determines whether or not the voltage level Vps of the power supply unit 16 is equal to or lower than the voltage level Vtf required for data communication (S300). As a result, if the voltage level Vps of the power supply unit 16 is equal to or lower than Vtf, the communication terminal 10 executes the power supply request sequence (S301). Thereby, electric power is supplied to each block of the communication terminal 10 from the communication control station 40 via the 1st communication part 13 (S302). The power supply by the power supply unit 16 is not performed unless the voltage level exceeds Vtf (S303). This is controlled in the reverse current prevention circuit.

  Next, an example of the processing flow of the power supply request sequence in S301 shown in FIG. 6 will be described with reference to FIG.

  The power management unit 15 notifies the control unit 11 of the determination result of S300. Receiving this, the control unit 11 transmits a power supply request to the communication control station 40 via the first communication unit 13 (S400).

  As described above, the communication terminal 10 requests the communication control station 40 to supply power by electromagnetic induction based on the relationship between the remaining amount of power and the power required for data communication. Therefore, for example, even when the remaining amount of power is low, an application for performing data communication can be newly activated. Further, for example, there is no shortage of remaining power during the execution of the application, and the process is not interrupted. Thereby, the certainty of data communication can be improved.

Note that the configurations of the communication system and the communication terminal according to the second embodiment are the same as those in FIGS. 1, 2, and 3 in which the first embodiment is described. Therefore, the description thereof is omitted here. However, the configuration of the power supply unit 16 in the communication terminal 10 is slightly different. The difference is that the power supply unit 16 according to the second embodiment has a power storage function as a secondary battery.

  An example of the flow of power supply processing in S208 (see FIG. 5) according to the second embodiment will be described with reference to FIG.

  In the power management unit 15, the communication terminal 10 determines whether or not the voltage level Vps of the power supply unit 16 is equal to or lower than the voltage level Vtf required for data communication (S500). As a result, if the voltage level Vps of the power supply unit 16 is equal to or lower than Vtf, the communication terminal 10 executes a power supply request sequence (S501). Thereby, electric power is supplied to each block of the communication terminal 10 from the communication control station 40 via the 1st communication part 13 (S502). At this time, the power supplied from the communication control station 40 is also supplied to the power supply unit 16, and the power supply unit 16 stores this power (S503).

  It is assumed that the voltage level Vps of the power supply unit 16 exceeds the voltage level Vtf required for data communication due to this power storage. Then, the control unit 11 of the communication terminal 10 notifies the communication control station 40 of the power supply stop via the first communication unit 13 (S505). Thereafter, the power supply unit 16 starts supplying power to each block of the communication terminal 10 (S506). And the communication terminal 10 performs the data communication by the 2nd communication part 14 with the supplied electric power.

  The power management unit 15 notifies the control unit 11 of the determination result of S300. Receiving this, the control unit 11 transmits a power supply request to the communication control station 40 via the first communication unit 13 (S600).

  Here, the communication control station 40 requests the communication terminal 10 for a charge corresponding to the amount of power to be supplied (S601). Receiving this, the control unit 11 of the communication terminal 10 performs settlement for the fee requested via the first communication unit 13 (S602). In this case, in the communication terminal 10, since it is necessary to pay a fee according to the amount of electric power to be supplied, monetary information corresponding to the payment amount already paid by the user is held. It should be noted that the charge request or charge settlement between the communication control station 40 and the communication terminal may be performed by a conventional charging process or settlement process, and the detailed description thereof is omitted.

(Embodiment 4)
Next, Embodiment 4 will be described. In the fourth embodiment, the configuration and operation of the communication control station 40 will be described. Note that the configuration of the communication system according to the fourth embodiment is the same as that of FIGS. 1, 2, and 3 in which the first embodiment is described, and therefore the description thereof is omitted here.
