<First embodiment>
FIG. 1 is a diagram illustrating an example of a system configuration of a payment system. In the settlement system, the server 30 and the base station are connected by an LTE network. Further, the base station and the communication device 20 are connected via radio. The settlement terminal 10 and the communication device 20 are connected via a wire.
The settlement terminal 10 reads and writes data from, for example, a transportation IC card (hereinafter, referred to as an IC card). The server 30 communicates with the settlement terminal 10 a plurality of times, and performs settlement processing based on data read by the settlement terminal 10 from an IC card or the like.
In the first embodiment, a process will be described in which the settlement terminal 10 transmits data for eliminating the non-communication state to the server 30, thereby eliminating the non-communication state and preventing a delay in the settlement process.

FIG. 2 is a diagram illustrating an example of a hardware configuration of the payment terminal 10. The payment terminal 10 includes a CPU 11, a storage unit 12, an LED unit 13, a display unit 14, an R / W unit 15, and a communication unit 16 as hardware configurations.
The CPU 11 controls the entire payment terminal 10. The storage unit 12 stores a program, data when the CPU 11 executes processing based on the program, and the like. The LED unit 13 emits light under the control of the CPU 11. The display unit 14 displays information based on the control of the CPU 11. The R / W unit 15 writes data to an IC card and reads data from the IC card under the control of the CPU 11. The communication unit 16 controls communication with an external device based on the control of the CPU 11.
The CPU 11 executes the processing based on the program stored in the storage unit 12, so that the function of the payment terminal 10 and the processing of the payment terminal 10 in FIGS. 4, 13, and 14 to be described later, FIGS. 9 and 11 are realized.

FIG. 3 is a diagram illustrating an example of a hardware configuration of the server 30. The server 30 includes a CPU 31, a storage unit 32, and a communication unit 33 as a hardware configuration.
The CPU 31 controls the entire server 30. The storage unit 32 stores a program, data when the CPU 31 executes processing based on the program, and the like. The communication unit 33 controls communication with an external device based on the control of the CPU 31.
The CPU 31 executes the processing based on the program stored in the storage unit 32, thereby the function of the server 30 and the processing of the server 30 shown in FIGS. 4, 13, and 14, which will be described later, and FIGS. 7, 10, and 12. Of the flowchart of FIG.

FIG. 4 is a diagram showing an example of a sales sequence of the thin client settlement. For simplification of the description, the description will be made using the settlement terminal 10 and the server 30 in the system configuration.
In the settlement, when the amount is input, the CPU 11 of the settlement terminal 10 (hereinafter, simply referred to as CPU 11) transmits a server call including the amount to the server 30 (SQ10).
Upon receiving the server call, the CPU 31 of the server 30 (hereinafter simply referred to as CPU 31) transmits the setting metadata to the settlement terminal 10 (SQ15).
Based on the received setting metadata, the CPU 11 that has made the setting transmits a business request such as a settlement to the server 30 using an IC card (SQ20).
Upon receiving the business request, the CPU 31 transmits a polling command (Polling command) to the settlement terminal 10 (SQ25).
Upon receiving the polling command, the CPU 11 causes the LED section 13 to emit light to indicate that the apparatus is in the polling state (Polling state). Then, the CPU 11 waits for the IC card to be held. Here, by waiting until the IC card is held, the non-communication state between the settlement terminal 10 and the server 30 becomes the longest in the sales sequence.
When the card is held up and the IC card is captured via the R / W unit 15, the CPU 11 transmits a polling command result (Polling command result) to the server 30 (SQ30). As described above, if the non-communication state is long, the transmission of the polling command result fails, and the CPU 11 has to perform the retransmission process of the polling command result, causing a delay in the settlement process. Therefore, as shown in FIG. 5, the CPU 11 transmits a ping command (ping command) to the server 30 from the reception of the polling command to the supplement of the IC card.

FIG. 5 is a flowchart illustrating an example of information processing of the payment terminal 10 according to the first embodiment.
In S100, the CPU 11 determines whether a polling command has been received. If a polling command has been received, the CPU 11 proceeds to S101. If a polling command has not been received, the CPU 11 repeats the processing of S100.
In S101, the CPU 11 transmits a ping command to the server 30.
In S102, the CPU 11 determines whether an IC card has been supplemented. The CPU 11 returns to the process of S100 when the IC card is supplemented, and returns to the process of S101 when the IC card is not supplemented. Returning to S101, the CPU 11 transmits a ping command to the server 30 again. In the present embodiment, the CPU 11 controls to transmit the ping command at an interval of 125 ms.
As shown in FIG. 5, the CPU 11 transmits a ping command to the server 30 from the reception of the polling command to the supplement of the IC card, thereby changing the non-communication state between the settlement terminal 10 and the server 30. Can be eliminated. As a result, retransmission and retransmission of polling command results can be reduced, and as a result, a delay in settlement processing can be prevented.

FIG. 6 is a diagram illustrating an example of an experimental result in which the CPU 11 transmits a ping command to the server 30 after receiving the polling command until the CPU 11 supplements the IC card.
As shown in FIG. 6, the CPU 11 transmits the ping command to the server 30 from the reception of the polling command to the supplement of the IC card, so that the retransmission of the polling command result becomes zero (0). Retransmissions are also decreasing.
When the non-communication state between the settlement terminal 10 and the server 30 continues for several seconds, it is estimated that the priority of packet communication is lowered compared to other sessions. As a result, retransmission and retransmission of the polling command result occur, and the settlement is delayed. Therefore, the CPU 11 transmits the ping command to the server 30 from the time when the polling command is received until the time when the IC card is supplemented. As a result, a non-communication state can be eliminated, the priority order is not lowered compared to other sessions, and a delay in settlement can be prevented.

Returning to the description of FIG.
Upon receiving the polling command result, the CPU 31 transmits a mutual authentication command to the settlement terminal 10 (SQ35).
Upon receiving the mutual authentication command, the CPU 11 authenticates the IC card and transmits a result of the mutual authentication to the server 30 (SQ40).
Upon receiving the mutual authentication result, the CPU 31 transmits a card information read command to the settlement terminal 10 (SQ45).
Upon receiving the card information read command, the CPU 11 reads information from the IC card and transmits the card information read result to the server 30 (SQ50).
Upon receiving the card information read result, the CPU 31 performs a payment process or the like based on the read result and the amount, and transmits a write command to the card to the payment terminal 10 (SQ55).
Upon receiving the write command to the card, the CPU 11 writes to the IC card, and transmits the write result to the server 30 (SQ60).
Hereinafter, the description of the payment processing is omitted because it is not involved in the processing for preventing the delay of the payment processing.
