Specifically, the plurality of LAN connection modes include a high-speed LAN connection mode, a medium-speed LAN connection mode, and a low-speed LAN connection mode. The high-speed LAN connection mode has a higher communication speed and consumes more power than the medium-speed LAN connection mode. The medium speed LAN connection mode has a higher communication speed and consumes more power than the low speed LAN connection mode. The difference in communication speed and power consumption is due to the size of the radio transmission output voltage and the frequency bandwidth used. The high-speed LAN connection mode is, for example, IEEE802.11ad. The medium speed LAN connection mode is, for example, IEEE802.11n. The low-speed LAN connection mode is, for example, IEEE802.11g.

The smartphone 22 is a specific example of an external terminal. As the external terminal, in addition to the smartphone 22, a TV, a recorder, a tablet personal computer, a laptop personal computer, and a desktop personal computer may be employed.

The relay traffic monitoring unit 13 outputs the relay traffic to the relay learning unit 14.

  The relay traffic monitoring unit 13 may be interposed between the wireless LAN communication unit 12 and the control unit 16 instead of being interposed between the wireless WAN communication unit 11 and the control unit 16.

Therefore, in this case, the relay traffic monitoring unit 13 separates and identifies both data communications based on the header information of the transmitted and received IP packets.

  FIG. 3 exemplifies a fluctuation pattern on the time axis of the relay communication amount. As shown in FIG. 3, the amount of relay communication has a property of regularly changing according to the day of the week and the time. Specifically, the amount of relay traffic at noon is considerably larger than the amount of relay traffic at Masako (around midnight). Further, the amount of relay communication gradually decreases from noon to the noon, and the amount of relay communication gradually increases from the noon to noon.

  Returning to FIG. 2, the relay learning unit 14 learns a daily fluctuation pattern of the relay traffic based on the relay traffic acquired by the relay traffic monitoring unit 13. Specifically, the relay learning unit 14 learns the daily fluctuation pattern of the relay traffic for each day of the week and for each time. FIG. 4 shows learning data of the relay learning unit 14. In the learning data shown in FIG. 4, the average amount of relay communication between 12:00 and 13:00 on Sunday was 50 MB. Similarly, the amount of relay traffic between 24:00 on Sunday and 1:00 on the next day averaged 1 MB. On average, the amount of relay communication between 12:00 and 13:00 on Monday was 30 MB. Similarly, the amount of relay communication from 24:00 on Monday to 1:00 on the next day averaged 5 MB.

  The mode determination unit 15 determines the WAN connection mode of the wireless WAN communication unit 11 based on the learning data of the relay learning unit 14. Specifically, the mode determination unit 15 is connected to the relay learning unit 14, refers to the learning data of the relay learning unit 14, and selects the WAN connection mode that is optimal at the present time according to the amount of relay traffic. decide. That is, the mode determination unit 15 refers to the learning data of the relay learning unit 14, selects a WAN connection mode with a higher communication speed in a time zone with a large amount of relay communication, and further increases a communication speed in a time zone with a small amount of relay communication. Select a lower WAN connection mode. For example, in a time zone in which the amount of relay communication per hour is greater than 10 MB (first relay communication amount), the WAN connection mode of the wireless WAN communication unit 11 is determined as the high-speed WAN connection mode. Also, for example, in a time zone where the relay traffic volume per hour is 10 MB (first relay traffic volume) or less and greater than 3 MB (second relay traffic volume), the WAN connection mode of the wireless WAN communication unit 11 is Is determined as the medium-speed WAN connection mode. Further, for example, in a time zone where the amount of relay communication per hour is 3 MB or less, the WAN connection mode of the wireless WAN communication unit 11 is determined as the low-speed WAN connection mode. Note that the first relay communication amount is larger than the second relay communication amount.

  In the example of FIG. 4, the mode determination unit 15 determines the WAN connection mode of the wireless WAN communication unit 11 as follows. That is, since the amount of relay communication between 12:00 and 13:00 on Sunday is 50 MB, the mode determination unit 15 performs the WAN connection mode of the wireless WAN communication unit 11 between 12:00 and 13:00 on Sunday. Is determined as a high-speed WAN connection mode. Further, since the amount of relay communication from 24:00 on Sunday to 1:00 on the next day is 1 MB, the mode determination unit 15 performs the WAN of the wireless WAN communication unit 11 between 24:00 on Sunday and 1:00 on the next day. The connection mode is determined as a low-speed WAN connection mode. Since the amount of relay communication between 12:00 and 13:00 on Monday is 30 MB, the mode determination unit 15 sets the WAN connection mode of the wireless WAN communication unit 11 between 12:00 and 13:00 on Monday at high speed. The WAN connection mode is determined. In addition, since the amount of relay communication from 24:00 on Monday to 1:00 on the next day is 5 MB, the mode determination unit 15 performs WAN of the wireless WAN communication unit 11 between 24:00 on Monday and 1:00 on the next day. The connection mode is determined as the medium speed WAN connection mode.

  The control unit 16 outputs a predetermined command to the wireless WAN communication unit 11 to switch the WAN connection mode of the wireless WAN communication unit 11 to the WAN connection mode determined by the mode determination unit 15. As a result, the wireless WAN communication unit 11 performs wireless communication with the wireless WAN base station 21 in the WAN connection mode determined by the mode determination unit 15.

  FIG. 5 shows a case where the WAN connection mode of the wireless WAN communication unit 11 is always set to the high-speed WAN connection mode regardless of the day of the week or the time zone. The broken line indicates the fluctuation pattern of the relay traffic, and the solid line indicates the WAN connection mode. In this case, although comfortable data communication is ensured at all times, since the constant high-speed WAN connection mode is used, the power consumption of the mobile router 10 is large, and the battery of the mobile router 10 is consumed greatly. In particular, the broken line and the solid line are greatly different depending on the time zone, and this difference means that there is room for suppressing power consumption.

  In contrast, FIG. 6 shows a case where the WAN connection mode of the wireless WAN communication unit 11 is changed based on learning data for each day of the week and for each time of day. The broken line indicates the fluctuation pattern of the relay traffic, and the solid line indicates the WAN connection mode. In this case, comfortable data communication is ensured by selecting the high-speed WAN connection mode at noon when the relay traffic volume is high, and consumption of the mobile router 10 is ensured by selecting the low-speed WAN connection mode when the relay traffic volume is low. The power is kept small. Since the WAN connection mode is automatically switched according to the learned variation pattern of the relay communication amount in this way, it is possible to achieve both a comfortable WAN communication environment and power consumption reduction without trouble.

(S130).

S170:
Next, the control unit 16 switches the WAN connection mode of the wireless WAN communication unit 11 to the WAN connection mode determined by the mode determination unit 15.
