(Configuration of wireless communication system)
FIG. 1 is a diagram illustrating a configuration example of a wireless communication system that performs wireless power transfer (hereinafter referred to as “WPT”) according to the present embodiment. The wireless communication system in FIG. 1 wirelessly receives a wireless control station (control station 101) connected to a server that performs an information distribution service for performing music distribution and the like, and an information distribution service such as music distribution from the control station 101 wirelessly. And the wireless terminal 102 to be configured. Here, the control station 101 further has a function of supplying power to the WPT, and the wireless terminal 102 further has a function of receiving power by the WPT. A power receiving apparatus such as the wireless terminal 102 can receive power from the control station 101 with sufficient efficiency within the WPT power supply area 103 of the control station 101.

  In the present embodiment, during the communication by the first application related to the information distribution service between the control station 101 and the wireless terminal 102, the control station 101 corresponds to the second application related to the WPT. Determine. If the control station 101 determines that the wireless terminal 102 is compatible with the second application, the control station 101 notifies the wireless terminal 102 of information indicating that the control station 101 itself supports WPT. Then, for example, when the wireless terminal 102 determines the state of its own battery and the remaining battery level is equal to or less than a predetermined value, the wireless terminal 102 is currently controlled by the first application based on the notified information. A message indicating that power can be received from the station 101 by WPT is displayed.

  In the following, a case where information distribution is used as the first application and WPT is used as the second application will be described, but the present invention is not limited to this. That is, the first application and the second application can be arbitrary applications. Further, for example, during the communication related to the first application, the above-described determination and notification regarding the second application useful for the first application may be performed. Further, for example, the control station 101 that is an information distribution apparatus may provide communication by a second application related to a service such as a charging service only for the wireless terminal 102 that has received the information.

  In this way, the control station 101 notifies the wireless terminal 102 that another application is available while executing an application such as information distribution with the wireless terminal 102. The wireless terminal 102 is configured to notify the user that the application is available when its state is suitable for executing the application with respect to the notified available application. Display may be performed.

  Hereinafter, the configurations and operations of the control station 101 and the wireless terminal 102 will be described in detail.

(Configuration of control station)
FIG. 2 is a block diagram illustrating a configuration example of hardware and functions of the control station 101. The control station 101 includes, for example, a first communication unit 201, a power transmission unit 204, a processor 207, a memory 208, and a second communication unit 209 as its configuration. Note that the control station 101 may have a function as a communication device that performs general information distribution, but here, a description will be given mainly of functional units related to processing to be described later, and descriptions of other functions will be omitted. .

  The first communication unit 201 performs at least wireless communication for the first application related to information distribution such as music distribution and other communication services. The first communication unit 201 performs at least one of transmission and reception of a wireless signal to and from the wireless terminal 102 via the antenna 203, and a server that performs an information distribution service via the wired connection 202 Then, information about the first application is transmitted and received.

  The power transmission unit 204 is a functional unit for performing power transmission by WPT. The power transmission unit 204 is connected to a DC power line 205, and includes, for example, a constant voltage source 2041 that converts the DC voltage to an optimum voltage when changing to an AC voltage, and a constant voltage source 2041 for performing wireless power transmission. An AC conversion unit 2042 that converts the output DC voltage into AC voltage is included. The power output from the AC conversion unit 2042 is sent to another device such as the wireless terminal 102 via the antenna coil 206.

  The processor 207 is configured by, for example, a CPU, MPU, ASIC, and the like, and controls the entire apparatus by executing a program stored in a storage unit such as the memory 208. Note that the processor 207 may control the entire apparatus in cooperation with a program stored in a storage unit such as the memory 208 and an OS (Operating System). In addition, the processor 207 controls the WPT, and also controls the second communication unit 209 for WPT authentication and the first communication unit 201 for the first application.

  The memory 208 is configured by either or both of ROM and RAM, and stores, for example, a program for performing various operations described below executed by the processor 207, and various information such as communication and power supply status. . Instead of the memory 208, a storage medium such as a flexible disk, a hard disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape, a nonvolatile memory card, or a DVD may be used.

  The second communication unit 209 performs WPT authentication and control signal exchange. The second communication unit 209 establishes a wireless connection with the wireless terminal 102 via the antenna 210 and performs at least one of transmission and reception of a wireless signal. Here, when the first communication unit 201 and the second communication unit 209 use the same frequency band, the antenna 203 and the antenna 210 and the high-frequency circuit of the first communication unit 201 and the second communication unit 209 are common. Things may be used. Further, when the communication to be performed by the first communication unit 201 and the communication to be performed by the second communication unit 209 are performed using the same communication system, the first communication unit 201 and the second communication unit 209 themselves are shared. May be. In this case, the communication to be performed by the first communication unit 201 and the communication to be performed by the second communication unit 209 can be divided and multiplexed by some radio resource such as time, frequency, code, and space. Note that data corresponding to each of communication to be performed by the first communication unit 201 and communication to be performed by the second communication unit 209 may be included and transmitted in one signal using the same resource. The control station 101 may be a BLE scanner, an advertiser that transmits an advertisement signal, or may function as both. Here, BLE is an abbreviation for Bluetooth (registered trademark) Low Energy. The control station 101 can operate as at least one of a BLE master and a slave. When the wireless terminal 102 is an apparatus that receives iBeacon, the control station 101 can operate as a BLE scanner and master, for example.

(Operation of control station)
Next, the operation of the control station 101 will be described using the flowchart of FIG. In general, a radio control station that performs an information distribution service or the like often keeps the communication function on while the power of the apparatus itself is turned on. Also assume that the wireless function is turned on.

  For example, when a user of the wireless terminal enters a Wi-Fi spot or a shopping street where information is transmitted by Wi-Fi communication or the like, the wireless terminal is connected to a wireless station that is permitted by the user for service distribution. You can establish and download information. When a wireless station that transmits information, such as iBeacon, transmits information on advertisement as a broadcaster, the wireless terminal can detect information as a scanner. When the wireless terminal 102 detects a beacon or the like, a wireless connection is established between the control station 101 and the wireless terminal 102 through an application (first application) that can be specified from the detected beacon or the like (S301). That is, the control station 101 establishes a wireless connection for the first application related to the information transmission with the wireless terminal 102 that receives the information transmitted by itself. Here, the control station 101 is a communication device that has transmitted a beacon, a communication device that is selected by the user based on the beacon, a communication device that is automatically connected by ucode, a Wi-Fi spot access point, a BLE It can be a master or the like. When the control station 101 is compatible with a plurality of wireless communication systems, the wireless communication system supported by the wireless terminal 102 or, when the wireless communication system is BLE, the connectable profile is detected. Is done.

  The control station 101 detects whether the wireless terminal 102 has a WPT power receiving function (S302). In addition, this detection is performed by acquiring the information of the wireless terminal 102 via the 1st communication part 201 which concerns on a 1st application, for example. For example, when the BLE is used in the first communication unit 201 and the control station 101 is a master in BLE connection, the control station 101 acquires information on the BLE capability of the wireless terminal 102. The capability information acquired at this time can indicate the presence or absence of the power reception capability of the WPT. Note that the capability information including information indicating whether or not the WPT has power reception capability may be exchanged when WPT authentication is performed by BLE.

  If the control station 101 does not detect that the wireless terminal 102 has a WPT power receiving function (NO in S302), the control station 101 ends the process. On the other hand, when the control station 101 detects that the wireless terminal 102 has a WPT power reception function (YES in S302), the control station 101 notifies the wireless terminal 102 that the control station 101 has a WPT power transmission function (S303). ). In step S303, the control station 101 notifies the wireless terminal 102 of information on another application WPT (second application) through communication related to a music distribution application or the like (first application). .

  Thereafter, the control station 101 waits for the wireless terminal 102 to be placed in the vicinity of the control station 101 (for example, placed on the power transmission antenna coil 206 of the control station 101) (S304). At this time, after notifying the wireless terminal 102 that the control station 101 has the WPT power transmission function in S303, the control station 101 determines the position and location of the control station 101 by light emission, voice, buzzer, etc. You may inform the user. Thereby, the control station 101 can prompt the user to place the wireless terminal 102 on the control station 101, and can prevent erroneous placement on other power transmission devices.

  The user of the wireless terminal 102 brings the wireless terminal 102 close to the control station 101 when the wireless terminal 102 needs to be charged (for example, the wireless terminal 102 is placed on the antenna coil 206 for power transmission of the control station 101). . When the control station 101 detects that the wireless terminal 102 is placed on the power transmission antenna coil 206 (YES in S304), the control station 101 subsequently transmits authentication power via the power transmission antenna coil 206. (S305).

  Thereafter, the control station 101 waits for detection of a WPT authentication signal via the second communication unit 209 (S306). Here, when the control station 101 can simultaneously communicate in parallel between the first communication unit 201 and the second communication unit 209, communication for the second application (WPT) while performing communication for the first application. Authentication signal) can be performed. Note that the case where the first communication unit 201 and the second communication unit 209 can simultaneously communicate in parallel is not only the control station 101 but also the wireless terminal 102, the first communication unit 401 and the second communication. This is a case where the unit 409 has an ability to perform communication simultaneously in parallel. Further, when the first communication unit 201 and the second communication unit 209 cannot communicate simultaneously in parallel, for example, communication for the first application may be interrupted and communication for the second application may be performed. . Further, the communication of the first communication unit 201 and the communication of the second communication unit 209 may be multiplexed not by time but by resources such as frequency, code, and space.

  When the control station 101 receives the authentication signal from the wireless terminal 102 via the second communication unit 209 (YES in S306), the control station 101 transmits a response signal to the authentication signal to the wireless terminal 102 (S307). By transmitting this response signal, the control station 101 can establish a wireless connection related to the second application (WPT) in addition to the wireless connection related to the first application (S308). Thereafter, the control station 101 starts normal power transmission by WPT (S309). Here, the communication for the first application and the communication for the second application may be performed simultaneously in parallel as described above. For example, the communication for the second application is performed for the communication for the first application. It may be performed after interruption or termination. Note that, as described above, the first communication unit 201 and the second communication unit 209 may be one communication unit related to one wireless communication system. In this case, two signals are transmitted in one transmission. Information about the application may be included.

  Thereafter, the control station 101 disconnects the wireless connection for the second application (for WPT) in response to the end of normal power transmission (S310) (S311). The end of normal power transmission can be caused by, for example, completion of charging by the wireless terminal 102 (reception of power reception completion), removal of the wireless terminal 102 out of the power transmission possible range, an error such as detection of a foreign object, or the like.

(Configuration of wireless terminal)
FIG. 4 is a block diagram illustrating a configuration example of hardware and functions of the wireless terminal 102. The wireless terminal 102 has a power receiving function based on WPT. The wireless terminal 102 includes, for example, a first communication unit 401, an application circuit 403, a power reception unit 404, a processor 407, a memory 408, a second communication unit 409, a battery 411, a remaining battery level detection unit 412, and a display unit 413. . Note that the wireless terminal 102 can have a function as a general wireless terminal such as a function of accepting an operation from a user, but here, a description will be given mainly of functional units related to processing to be described later, and other functions. The description about is omitted.

  Similar to the first communication unit 201 of the control station 101 described above, the first communication unit 401 performs communication related to the first application. The first communication unit 401 performs at least one of transmission and reception of a radio signal with the control station 101 via the antenna 402. The first communication unit 401 is connected to the application circuit 403 and transmits / receives information on the first application to / from the application circuit 403.

  The power reception unit 404 is connected to the antenna coil 406 and receives AC power transmitted from the control station 101 by the WPT via the antenna coil 406. The power receiving unit 404 is further connected to the DC power supply line 405 and converts the AC power into DC, and converts the rectified DC voltage into a voltage suitable for use in the wireless terminal 102. A constant voltage source 4042 is included. The constant voltage source 4042 supplies power to, for example, the first communication unit 401, the application circuit 403, the second communication unit 409, and the battery 411. Note that power needs to be supplied to the processor 407 and the memory 408, but illustration is omitted here for the sake of simplicity. Note that power from the power receiving unit 404 is not supplied to the processor 407 and the memory 408, and power may be supplied in another arbitrary format. Note that power can be supplied to the first communication unit 401, the second communication unit 409, or the application circuit 403 from at least one of the power output from the power reception unit 404 and the battery 411.

  The processor 407 includes, for example, a CPU, MPU, ASIC, and the like, and controls the entire apparatus by executing a program stored in a storage unit such as the memory 408. The processor 407 may control the entire apparatus by cooperation between a program stored in a storage unit such as the memory 408 and an OS (Operating System). In addition, the processor 407 controls WPT authentication power detection, authentication signal transmission and other WPT initial settings, control during power reception, and transmission and reception of control signals related to those controls via the second communication unit 409. The WPT is controlled. Further, the processor 407 also controls the first communication unit 401 for the first application.

  The memory 408 is composed of either or both of ROM and RAM, and stores, for example, a program for performing various operations described later, and various information such as communication and power supply status, which are executed by the processor 407. . Instead of the memory 408, a storage medium such as a flexible disk, a hard disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape, a nonvolatile memory card, or a DVD may be used.

  The second communication unit 409 performs WPT authentication and control signal exchange. The second communication unit 409 establishes a wireless connection with the control station 101 via the antenna 410 and performs at least one of transmission and reception of a wireless signal. Here, when the first communication unit 401 and the second communication unit 409 use the same frequency band, the antenna 402 and the antenna 410 and the high-frequency circuit of the first communication unit 401 and the second communication unit 409 are common. Things may be used. Further, when the communication to be performed by the first communication unit 401 and the communication to be performed by the second communication unit 409 are performed using the same communication system, the first communication unit 401 and the second communication unit 409 themselves are shared. May be. In this case, the communication to be performed by the first communication unit 401 and the communication to be performed by the second communication unit 409 can be divided and multiplexed by some radio resource such as time, frequency, code, and space. Note that data corresponding to the communication to be performed by the first communication unit 401 and the communication to be performed by the second communication unit 409 may be included in one signal using the same resource and transmitted. The wireless terminal 102 may be a BLE scanner, an advertiser that transmits an advertisement signal, or may function as both. The wireless terminal 102 can operate as at least one of a BLE master and a slave. In the case where the wireless terminal 102 is an apparatus that receives iBeacon, for example, the wireless terminal 102 can operate as an advertiser and a slave that transmit authentication information as an advertisement signal.

  The battery 411 is, for example, a battery that can be charged by the power received by the power receiving unit 404, and the battery remaining amount detecting unit 412 detects the remaining amount of the battery 411 and transmits the result to the processor 407. The processor 407 can display the remaining amount of the battery 411 on the display unit 413. Note that the display unit 413 is an arbitrary functional unit that can present information to the user. For example, the display unit 413 is a display that presents information on a screen, a speaker that presents information by voice, lighting / flashing / color, and the like. It can be configured by an LED or the like that presents information. The display unit 413 may be configured by a vibrator or the like that presents information using vibration. The processor 407 may control the display unit 413 to display a warning message when the remaining amount of the battery 411 falls below a predetermined value.

(Wireless terminal operation)
Next, the flow of processing executed by the wireless terminal 102 will be described with reference to FIG. Since a user of a wireless terminal such as a smartphone often keeps the wireless function of the wireless terminal turned on, the wireless function of the wireless terminal 102 here is also turned on.

  The wireless terminal 102 establishes a wireless connection for the first application other than WPT via the first communication unit 401 with the control station 101 (S501). Then, the wireless terminal 102 transmits capability information including information indicating whether the wireless terminal 102 has a WPT power receiving function to the control station 101 (S502). For example, when the first communication unit 401 uses BLE, and the wireless terminal 102 is a slave in a BLE connection, the wireless terminal 102 sends information on the BLE capability of the wireless terminal 102 to the control station 101 that is the master. Can be sent. The capability information transmitted at this time can indicate the presence or absence of the power reception capability of the WPT. Note that the capability information including information indicating whether or not the WPT has power reception capability may be exchanged when WPT authentication is performed by BLE. In addition, when the wireless system is BLE and the wireless terminal 102 is a slave, the method of notifying the function of the WPT by the capability information exchange packet transmitted by the master has been described. Information on the presence or absence of capability may be exchanged. Note that the wireless terminal 102 may notify the control station 101 that it has a WPT power receiving function according to its own state, for example, only when power reception is required for charging or the like. .

  Thereafter, the wireless terminal 102 detects that the control station 101 that has detected that the wireless terminal 102 has a WPT power receiving function has received a notification that the control station 101 has a WPT power transmitting function (S503). By receiving this notification, the wireless terminal 102 can detect that the control station 101 has the WPT power transmission function.

  The wireless terminal 102 determines whether or not the remaining amount of the battery 411 is less than a predetermined value (S504). When the remaining amount is less than the predetermined value (YES in S504), the control station 101 notifies the user of the WPT. (S505). This notification may be performed regardless of the remaining amount of the battery 411. For example, if the wireless terminal 102 is notified that the control station 101 has a WPT power transmission function during communication for the first application, the wireless terminal 102 displays an icon notifying that the WPT can receive power from the control station 101. You may make it do. Even in this case, when the remaining amount of the battery 411 is less than the predetermined value, the wireless terminal 102 clearly indicates that it can receive power from the control station 101 through the WPT together with a message prompting the user to charge. You may make it do. In any case, the wireless terminal 102 can receive power from the control station 101 by the WPT, and can receive power by bringing the wireless terminal 102 closer to (mounted on) the control station 101. This can be notified to the user.

  Thereafter, it is assumed that the user places the wireless terminal 102 in a range in which the control station 101 can transmit power by WPT, such as mounting on the antenna coil 206 of the control station 101. When the wireless terminal 102 enters the power supply area 103 of the control station 101, the wireless terminal 102 can receive the authentication power from the control station 101 (YES in S506), and responds to the reception of the authentication power. The authentication signal is transmitted (S507). Note that the authentication signal here is transmitted via the second communication unit 409. Here, when the wireless terminal 102 can simultaneously communicate in parallel between the first communication unit 401 and the second communication unit 409, communication for the second application (WPT) while performing communication for the first application. Authentication signal) can be performed. Note that the case where the first communication unit 401 and the second communication unit 409 can simultaneously communicate in parallel is the case where not only the wireless terminal 102 but also the control station 101 has the first communication unit 201 and the second communication. This is a case where the unit 209 has the capability of performing simultaneous communication in parallel. In addition, when the first communication unit 401 and the second communication unit 409 cannot communicate simultaneously in parallel, for example, communication for the first application may be interrupted and communication for the second application may be performed. . Further, the communication of the first communication unit 401 and the communication of the second communication unit 409 may be multiplexed not by time but by resources such as frequency, code, and space.

  After transmitting the authentication signal, the wireless terminal 102 waits for a response signal to the authentication signal (S508). When receiving the response signal (YES in S508), the wireless terminal 102 establishes a wireless connection with the control station 101 in the second communication unit 409 related to the second application (WPT) (S509). Then, after establishing the wireless connection in the second communication unit 409, the wireless terminal 102 starts normal power reception by the WPT (S510), and starts charging the battery 411. Here, the communication for the first application and the communication for the second application may be performed simultaneously in parallel as described above. For example, the communication for the second application is performed for the communication for the first application. It may be performed after interruption or termination. Note that, as described above, the first communication unit 401 and the second communication unit 409 may be one communication unit related to one wireless communication system. In this case, two signals are transmitted in one transmission. Information about the application may be included.

  Thereafter, the wireless terminal 102 disconnects the wireless connection for the second application (for WPT) (S512) in response to the end of normal power reception (S511). Note that the end of normal power reception is due to, for example, completion of charging by the wireless terminal 102 (transmission of power reception completion notification to the control station 101), removal of the wireless terminal 102 out of the power transmission range, detection of foreign matter, etc. Can occur.

  As described above, the control station 101 determines whether the wireless terminal 102 that is the counterpart device that is executing communication for the information distribution application is compatible with WPT, and the wireless terminal 102 is compatible with WPT. To the control station 101. Thereby, for example, when the remaining charge amount is less than a predetermined value, the user of the wireless terminal 102 disconnects communication related to the first application or turns off the power to move to a chargeable place. Disappears. As a result, the convenience of the user of the wireless terminal 102 is improved, and the control station 101 can also complete the distribution of information to the wireless terminal 102 regardless of the remaining battery level of the wireless terminal 102. As described above, the application is not limited to information distribution and WPT. That is, the same processing can be executed by using the above-described information distribution and WPT as any two applications. For example, when there is a second application that can be used in connection with the first application, the control station 101 can correspond to the second application to the wireless terminal 102 that is executing communication related to the first application. You can be notified. For the communication device other than the wireless terminal 102 that is executing communication related to the first application, the control station 101 determines whether the communication device can support the second application, and the control station 101 supports It is possible to eliminate notification that it is possible. Thereby, the control station 101 can prevent notification of unnecessary information, and can provide a service such as power transmission by WPT, for example, limited to the information distribution destination device.

  In the above description, the wireless communication between the control station 101 and the wireless terminal 102 is based on BLE. However, this may be another wireless communication system such as a wireless LAN. Furthermore, the radio communication system used by the first communication unit related to the first application may be different from the radio communication system used by the second communication unit related to the second application. For example, the first communication unit may use a wireless LAN, and the second communication unit may use BLE. Further, since the control station 101 is a wireless communication device wired to the server, the control station 101 is a transmission side in the case of application download or the like, but is configured to receive information wirelessly from other devices. Also good. That is, the control station 101 may be a wireless communication device having a general wireless transmission / reception function. The control station 101 may have a wireless LAN access point function.

  In addition, when the control station 101 having the WPT function at the information transmission base or the like connects with the first application, software for the second application for notifying the user that it has the WPT function is automatically installed. The wireless terminal 102 may be downloaded.
