(Embodiment 1)
The configuration of the communication system 1 according to the embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an example of the configuration of the communication system 1. As shown in FIG. 1, the communication system 1 includes a communication device 10 and a communication device 20. The communication system 1 is a system that communicates with public lines including the data communication network 100 and the voice line network 200. The communication device 20 functions as a relay device that performs communication between the communication device 10 and the data communication network 100 and communication between the communication device 10 and the voice line network 200 via the communication device 20. The communication device 10 has a function of performing data communication with another device via the data communication network 100 and a function of performing a call with another device via the voice line network 200.

  The communication device 10 includes a battery 13, a communication unit 15, a communication unit 16, and a control unit 17. The battery 13 supplies power to various functional units of the communication device 10. The communication unit 15 enables communication between the data communication network 100 and the communication device 10 and communication between the voice line network 200 and the communication device 10. Communication by the communication unit 15 is wireless communication having a relatively long communicable distance, and is performed without using the communication device 20. The communication methods supported by the communication unit 15 include, for example, LTE (Long Term Evolution), W-CDMA (Wideband Code Division Multiple Access), CDMA2000, PDC (Personal Digital Cellular), GSM (registered trademark) (Global Mobile). Communications), PHS (Personal Handy-phone System), etc., but are not limited to these.

  The communication unit 16 enables communication with the communication device 20. Communication by the communication unit 16 is short-range communication with a relatively short communicable distance, and is performed without going through another device. Examples of the communication method supported by the communication unit 16 include, but are not limited to, Bluetooth, Wi-Fi (registered trademark), visible light communication, infrared communication, and ZigBee. The control unit 17 executes various controls.

  The communication device 20 includes a battery 23, a communication unit 25, a communication unit 26, and a control unit 27. The battery 23 supplies power to various functional units of the communication device 20. The communication unit 25 enables communication between the data communication network 100 and the communication device 20 and communication between the voice line network 200 and the communication device 20. Communication by the communication unit 25 is wireless communication having a relatively long communicable distance. The communication method supported by the communication unit 25 includes the same communication method as the example of the communication method supported by the communication unit 15 described above, but the communication method supported by the communication unit 25 is the communication supported by the communication unit 15. It may be different from the system.

  The communication unit 26 enables communication with the communication device 10. Communication by the communication unit 26 is short-range communication with a relatively short communicable distance, and is performed without going through another device. The communication method supported by the communication unit 26 is a communication method corresponding to the communication method supported by the communication unit 16.

  Communication between the communication device 20 and the communication device 10 is executed via the first route PT1 or the second route PT2. The first route PT1 is a route for data communication. The second route PT2 is a route for a call. The first route PT1 and the second route PT2 may be realized by different communication methods. For example, the first route PT1 may be realized by Wi-Fi, and the second route PT2 may be realized by Bluetooth. For example, the first route PT1 may be realized by a Bluetooth data communication profile, and the second route PT2 may be realized by a Bluetooth call profile.

  When the first route PT1 and the second route PT2 are realized by different communication methods, the communication unit 16 and the communication unit 26 may include a communication unit for each route. For example, as shown in FIG. 2, the communication unit 16 includes a communication unit 16a for the first route PT1 and a communication unit 16b for the second route PT2, and the communication unit 26 is connected to the first route PT1. A communication unit 26a for the second path PT2 and a communication unit 26b for the second path PT2 may be provided. The communication unit 16a and the communication unit 26a support the same communication method. The communication unit 16b and the communication unit 26b support the same communication method.

  The first path PT1 may also serve as the second path PT2. That is, the first route PT1 may be used for both data communication and a telephone call. In this case, for example, it is determined whether a packet flowing through the first path PT1 is a data communication packet or a call packet by referring to the header.

  In the present embodiment, communication between the communication device 20 and the communication device 10 is further executed via the third path PT3. The third path PT3 is a path for the communication device 10 to acquire information regarding the remaining amount of the battery 23 of the communication device 20. Information regarding the remaining amount of the battery 23 is periodically transmitted from the communication device 20 to the communication device 10. It is preferable that the information regarding the remaining amount of the battery 23 is transmitted with a frequency and a data amount that hardly affect the power consumption of the communication device 20. The second path PT2 may also serve as the third path PT3. That is, the information regarding the remaining amount of the battery 23 may be transmitted from the communication device 20 to the communication device 10 via the second path PT2.

  Data communication by the communication device 10 is performed using either one of the two paths. One route is a route via the first route PT1 between the communication unit 16 and the communication unit 26 and the fourth route PT4 between the communication unit 25 and the data communication network 100. When data communication is performed through this path, the communication device 20 functions like a router or a modem. The other route is a route via the sixth route PT6 between the communication unit 15 and the data communication network 100. When data communication is performed through this route, the communication device 20 is not particularly involved in communication.

  Similarly, a call by the communication device 10 is performed using one of the two paths. One route is a route via the second route PT2 between the communication unit 16 and the communication unit 26 and the fifth route PT5 between the communication unit 25 and the voice line network 200. When a call is made through this route, the communication device 20 functions like a parent device in a parent-child phone. That is, the outgoing and incoming calls are performed using the telephone number of the communication device 20 instead of the telephone number of the communication device 10. The other route is a route via the seventh route PT7 between the communication unit 15 and the voice network 200. When a call is made through this route, the outgoing and incoming calls are made using the telephone number of the communication device 10.

  The control unit 17 of the communication device 10 controls a path used in data communication and a call based on the remaining amount of the battery 23 of the communication device 20. In the description of the present embodiment, in the data communication and the telephone call, the communication via the communication device 20 is more normally used than the communication not via the communication device 20 in some points such as quality, fee, and speed. Assume that it is advantageous. Furthermore, it is assumed that the communication device 20 is in a position where it can communicate with the communication device 10 via the first route PT1 and the second route PT2.

  The communication control by the communication device 10 will be described in more detail with reference to FIGS. FIG. 3 is a diagram illustrating an example of threshold values for communication control. As illustrated in FIG. 3, the communication device 10 sets two threshold values, a first threshold value and a second threshold value, for the remaining amount of the battery 23 of the communication device 20. The second threshold is set lower than the first threshold. The first threshold value and the second threshold value may be configured to be settable by the user.

  FIG. 4 is a diagram illustrating an example of normal control. In step S11 shown in FIG. 4, the remaining amount of the battery 23 is full, and the first function and the second function of the communication devices 10 and 20 are operating. The first function is a function for the communication device 20 to relay data communication of the communication device 10. The second function is a function for the communication device 20 to relay a call of the communication device 10.

  When the first function of the communication devices 10 and 20 is operating, data transmission from the communication device 10 is performed via the communication device 20. When the first function of the communication devices 10 and 20 is operating, data transmission to the communication device 10 is performed via the communication device 20 or the sixth path PT6 by the communication unit 15.

  When the second function of the communication devices 10 and 20 is operating, transmission of a call from the communication device 10 is normally performed via the communication device 20. When the second function of the communication devices 10 and 20 is operating, an incoming call to the communication device 10 is performed via the communication device 20 or the seventh path PT7 by the communication unit 15.

  In step S12, the communication device 20 consumes power, and the remaining amount of the battery 23 is lower than the first threshold value. When the communication device 10 detects that the remaining amount of the battery 23 has fallen below the first threshold, the communication device 10 stops the first function of the communication devices 10 and 20 while maintaining the second function. Specifically, the communication device 10 stops the first function of the communication device 10 itself, and further instructs the communication device 20 to stop the first function. Thereby, the first path PT1 is cut.

  The stop of the first function may be performed by software or may be performed by hardware. When the stop of the first function is performed by software, the communication devices 10 and 20 stop the software processing related to the first function. When the stop of the first function is performed by hardware, the communication devices 10 and 20 stop the circuit related to the first function. The stop of the first function may be performed simply by stopping the transmission of the radio signal for the first function.

  The communication device 10 receives a call specifying the telephone number of the communication device 10 as a calling party and a call specifying the telephone number of the communication device 20 as a calling party. Among these, a call that designates the telephone number of the communication device 20 as a caller is received by the communication device 10 via the communication device 20 by the second function. For this reason, when the remaining amount of the battery 23 is low and the communication device 20 cannot continue the operation, the communication device 10 cannot receive a call specifying the telephone number of the communication device 20 as a caller.

  When the remaining amount of the battery 23 falls below the first threshold, the first function is stopped without stopping the second function, thereby communicating a call specifying the telephone number of the communication device 20 as a caller. The period that the device 10 can receive can be extended. That is, the power consumption of the communication device 20 can be reduced by stopping the first function. Furthermore, by not stopping the second function, an incoming voice call via the communication device 20 can be received by the communication device 10. As a result, it is possible to reduce the possibility that a situation in which the user of the communication device 10 cannot receive an important call will occur.

  When stopping the first function, the communication device 20 may stop the function for communicating with the data communication network 100 and disconnect the fourth path PT4. The stop of the function for communicating with the data communication network 100 may be performed by software or may be performed by hardware. Thus, by stopping the function for communicating with the data communication network 100, the power consumption of the communication device 20 can be further reduced.

  In step S13, the communication device 20 further consumes power, and the remaining amount of the battery 23 is below the second threshold value. When the communication device 10 detects that the remaining amount of the battery 23 has fallen below the second threshold, the communication device 10 stops the second function of the communication devices 10 and 20. Specifically, the communication device 10 stops the second function of the communication device 10 itself, and further instructs the communication device 20 to stop the second function. Thereby, 2nd path | route PT2 is cut | disconnected.

  The stop of the second function may be performed by software or may be performed by hardware. When the stop of the second function is performed by software, the communication devices 10 and 20 stop the software processing related to the second function. When the stop of the second function is performed by hardware, the communication devices 10 and 20 stop the circuit related to the second function. The stop of the second function may be performed simply by stopping the transmission of the radio signal for the second function.

  Due to the stop of the second function, the communication device 10 cannot receive a call that designates the telephone number of the communication device 20 as a caller. However, since the power consumption of the communication device 20 can be reduced, it is possible to extend the period during which the communication device 20 can maintain the minimum functions such as display of telephone directory data and communication history data.

  When stopping the second function, the communication device 20 may stop the function for communicating with the voice line network 200 and disconnect the fifth path PT5. The stop of the function for communicating with the voice network 200 may be performed by software or hardware. Thus, by stopping the function for communicating with the voice network 200, the power consumption of the communication device 20 can be further reduced.

  FIG. 5 is a diagram illustrating an example of control during charging of the battery 23. In step S21 shown in FIG. 5, as in step S13 shown in FIG. 4, the remaining amount of the battery 23 is below the second threshold. For this reason, in step S21, the first function and the second function are stopped.

  In step S22, the remaining amount of the battery 23 exceeds the second threshold due to charging. When the communication device 10 detects that the remaining amount of the battery 23 exceeds the second threshold value, the communication device 10 activates the second function of the communication devices 10 and 20 while stopping the first function. Specifically, the communication device 10 activates the second function of the communication device 10 itself, and further instructs the communication device 20 to activate the second function. Thereby, the second path PT2 is established. At this time, if the function for communicating with the voice network 200 is stopped, the communication device 20 activates this function and establishes the fifth path PT5.

  When the remaining amount of the battery 23 exceeds the second threshold, the communication device 10 can receive a call specifying the telephone number of the communication device 20 as a caller by first activating the second function. To do. As a result, it is possible to reduce the possibility that a situation in which the user of the communication device 10 cannot receive an important call will occur. Furthermore, charging of the battery 23 can be accelerated by keeping the first function stopped.

  In step S23, the remaining amount of the battery 23 exceeds the first threshold due to charging. When the communication device 10 detects that the remaining amount of the battery 23 exceeds the first threshold, the communication device 10 activates the first functions of the communication devices 10 and 20. Specifically, the communication device 10 activates the first function of the communication device 10 itself, and further instructs the communication device 20 to activate the first function. Thereby, the first path PT1 is established. At this time, when the function for communicating with the data communication network 100 is stopped, the communication device 20 activates this function and establishes the fourth path PT4.

  By activating the first function when the remaining amount of the battery 23 exceeds the first threshold, the communication device 10 performs data communication through an advantageous route while ensuring sufficient operation time of the communication device 20. It can be carried out.

  The first threshold value and the second threshold value may be different between the normal time and the charging time. The first threshold value and the second threshold value may be set to the same value.

  The configuration of the communication device 10 will be described in more detail with reference to FIG. FIG. 6 is a block diagram illustrating a configuration of the communication device 10. As illustrated in FIG. 6, the communication device 10 includes a display unit 11, an operation unit 12, a battery 13, a battery control unit 14, a communication unit 15, a communication unit 16, a control unit 17, and a storage unit 18. And have.

  The display unit 11 displays information for the user. The display unit 11 has a display panel for displaying information. The operation unit 12 receives user operations. The operation unit 12 includes input devices such as buttons, switches, and touch sensors for receiving operations.

  The battery 13 supplies power to various functional units of the communication device 10. The battery control unit 14 controls the power supplied by the battery 13 according to the situation. Further, the battery control unit 14 monitors the remaining amount of the battery 13 and notifies the control unit 17 of the remaining amount.

  The communication unit 15 enables communication between the data communication network 100 and the communication device 10 and communication between the voice line network 200 and the communication device 10. The communication unit 16 enables communication with the communication device 20.

  The control unit 17 is an arithmetic processing device. The arithmetic processing unit includes, for example, a CPU (Central Processing Unit), an SoC (System-on-a-chip), an MCU (Micro Control Unit), an FPGA (Field-Programmable Gate Array), and the like. Not. The control unit 17 comprehensively controls the operation of the communication device 20 to realize various functions.

  Specifically, the control unit 17 executes instructions included in the program stored in the storage unit 18 while referring to the data stored in the storage unit 18 as necessary. And the control part 17 controls a function part according to data and a command, and implement | achieves various functions by it. Examples of the function unit include, but are not limited to, the display unit 11, the battery control unit 14, the communication unit 15, the communication unit 16, and the like. The control unit 17 may change the control according to the detection result of the detection unit. Examples of the detection unit include, but are not limited to, the operation unit 12, the battery control unit 14, the communication unit 15, and the communication unit 16.

  The storage unit 18 stores programs and data. The storage unit 18 is also used as a work area for temporarily storing the processing result of the control unit 17. The storage unit 18 may include any non-transitory storage medium such as a semiconductor storage medium and a magnetic storage medium. Non-transitory storage media include, for example, optical disks such as CD (registered trademark), DVD (registered trademark), and Blu-ray (registered trademark), magneto-optical disks, magnetic storage media, memory cards, and solid state storage. Although a medium etc. are included, it is not limited to these. The storage unit 18 may include a plurality of types of storage media. The storage unit 18 may include a combination of a portable storage medium such as a memory card, an optical disk, or a magneto-optical disk and a storage medium reader. The storage unit 18 may include a storage device that is used as a temporary storage area such as a RAM (Random Access Memory).

  The storage unit 18 stores a communication control program 18a and setting information 18b.

  The communication control program 18a provides functions related to various controls related to communication. The control related to communication includes control for data communication, control for call, control shown in FIGS.

  The setting information 18b holds various setting values related to the operation of the communication device 10. The setting values related to the operation of the communication device 10 include the first threshold value and the second threshold value shown in FIG.

  The operation of the communication device 10 will be described in more detail with reference to FIGS. FIG. 7 is a flowchart illustrating an example of communication control. FIG. 8 is a flowchart showing an example of an operation at the time of outgoing. The operations shown in FIGS. 7 and 8 are realized by the control unit 17 executing the communication control program 18a. The operation shown in FIG. 7 is repeatedly executed. The operation shown in FIG. 8 is executed at the time of data communication or outgoing call.

  As shown in FIG. 7, in the communication control, the control unit 17 acquires information related to the remaining amount of the battery 23 of the communication device 20 (router) (step S101). The acquired information is stored in the storage unit 18 as history information indicating a change in the remaining amount for a certain period (or a certain amount). Then, the control unit 17 determines whether or not the remaining amount of the battery 23 is decreasing based on the acquired information and the information stored in the storage unit 18 (step S102). That the remaining amount of the battery 23 tends to decrease means that the communication device 20 is in a normal state. On the other hand, the fact that the remaining amount of the battery 23 does not tend to decrease means that the communication device 20 is being charged.

  When the remaining amount of the battery 23 tends to decrease (step S102, Yes), the control unit 17 determines whether the remaining amount of the battery 23 is lower than the first threshold (step S103). When the remaining amount of the battery 23 is lower than the first threshold (step S103, Yes), the control unit 17 instructs the relay device to stop the first function (step S104). Furthermore, the control part 17 stops the 1st function of the communication apparatus 10 (step S105). Steps S104 and S105 are executed only when the first function is operating.

  Subsequently, the control unit 17 determines whether or not the remaining amount of the battery 23 is lower than the second threshold (step S106). When the remaining amount of the battery 23 is lower than the second threshold (step S106, Yes), the control unit 17 instructs the relay device to stop the second function (step S107). Furthermore, the control part 17 stops the 2nd function of the communication apparatus 10 (step S108). Steps S107 and S108 are executed only when the second function is operating.

  When the remaining amount of the battery 23 is not lower than the second threshold (No at Step S106), Step S107 and Step S108 are not executed. When the remaining amount of the battery 23 is not lower than the first threshold (No at Step S103), Steps S104 to S108 are not executed.

  When the remaining amount of the battery 23 does not tend to decrease (No at Step S102), the control unit 17 determines whether the remaining amount of the battery 23 is higher than the second threshold (Step S109). When the remaining amount of the battery 23 is higher than the second threshold value (step S109, Yes), the control unit 17 activates the second function of the communication device 10 (step S110). Furthermore, the control unit 17 instructs the relay device to start the second function (step S111). Steps S110 and S111 are executed only when the second function is stopped.

  Subsequently, the control unit 17 determines whether or not the remaining amount of the battery 23 is higher than the first threshold (step S112). When the remaining amount of the battery 23 is higher than the first threshold (step S112, Yes), the control unit 17 activates the first function of the communication device 10 (step S113). Further, the control unit 17 instructs the relay device to start the first function (step S114). Steps S113 and S114 are executed only when the first function is stopped.

  When the remaining amount of the battery 23 is not higher than the first threshold (No at Step S112), Step S113 and Step S114 are not executed. When the remaining amount of the battery 23 is not higher than the second threshold (No at Step S109), Steps S110 to S114 are not executed.

  As shown in FIG. 8, when detecting a call request (step S201), the control unit 17 determines whether the call request is for a call or data communication (step S202). .

  When the call request is for a call (step S202, Yes), the control unit 17 determines whether the call request is for an emergency call (step S203). An emergency call is a call to the police, a fire department, etc. performed in an emergency. Whether or not the transmission request is for emergency transmission is determined based on, for example, the telephone number of the transmission destination. When the call request is for emergency call (step S203, Yes), the control unit 17 performs a call using the communication unit 15 without using the communication device 20 (router) (step S204). . Thereby, a call with high urgency can be more reliably performed. The controller 17 may temporarily stop the second function of the intermediary device during a call with an emergency call. Thereby, the power consumption of the communication apparatus 20 can be reduced.

  When the call request is not for emergency call (step S203, No), the control unit 17 determines whether the call request is for free call (step S205). A free call is a call in which the call charge is not charged to the caller. Whether or not the call request is for a free call is determined based on, for example, the telephone number of the call destination. When the outgoing call request is for a free call (step S205, Yes), the control unit 17 executes the call using the communication unit 15 without going through the intermediary device (step S204). As a result, a call can be executed using a more advantageous route. The control unit 17 may temporarily stop the second function of the intermediary device during the free call. Thereby, the power consumption of the communication apparatus 20 can be reduced.

  If the call request is not for a free call (No at Step S205), the control unit 17 determines the state of the second function (Step S206). When the second function is stopped (step S207, Yes), the control unit 17 performs a call using the communication unit 15 without using a relay device (step S204). When the second function is not stopped (step S207, No), the control unit 17 requests the relay device to relay the call using the second function (step S208).

  If the call request is not for a call (No at Step S202), the control unit 17 determines the state of the first function (Step S209). When the first function is stopped (step S210, Yes), the control unit 17 performs data communication using the communication unit 15 without using a relay device (step S211). When the first function is not stopped (No at Step S210), the control unit 17 requests the relay device to relay data communication using the first function (Step S212).
