Description

  The present invention relates to a wireless communication method and program.

  In recent years, wireless communication devices that perform wireless communication based on Bluetooth (registered trademark), which is a short-range wireless communication standard, are becoming widespread.

  For example, patent document 1 is disclosing the terminal cooperation system provided with the terminal device and portable terminal device which are connected via near field communication. In this system, pairing for sharing a shared key is performed between the terminal device and the mobile terminal device. When re-connecting with a paired terminal device, the portable terminal device uses a shared key to log in to the OS (Operating System) of the terminal device to establish a connection with the terminal device.

JP 2013-214257 A

  Short-range wireless communication and pairing as in the terminal cooperation system of Patent Document 1 are also performed between wireless communication devices such as smartphones and electronic watches that are currently popular. “Pairing” means a process of performing mutual authentication between wireless communication apparatuses that establish a connection for the first time and registering information of a wireless communication apparatus that is a connection destination. When the wireless communication device reconnects with the wireless communication device that has been paired once, the wireless communication device is connected by omitting processing such as mutual authentication.

  Here, there is a wireless communication device that can perform pairing with only one wireless communication device as a wireless communication device that performs short-range wireless communication. For example, an electronic watch that can be paired with only one smartphone.

  When connecting such a wireless communication device to another wireless communication device that is not paired, the user must perform an operation for canceling the existing pairing before pairing with another wireless communication device. I cannot do the operation to make it ring.

  For example, in the case of the terminal cooperation system of Patent Document 1, the operation for canceling the pairing is an operation of deleting information on the shared key stored in the storage units of the terminal device and the mobile terminal device.

  In addition, in the case of an electronic watch that can be paired with only one smartphone, even if it becomes necessary to redo pairing due to a malfunction due to a smartphone OS update, the above erasing operation is performed to cancel the existing pairing. Is required.

  As described above, in the configuration of a conventional wireless communication device that performs short-range wireless communication, an operation for deleting information such as a shared key from the storage unit of each wireless communication device is required to cancel pairing. Operation is complicated. In addition, even when pairing is reestablished after cancellation of pairing, the operation becomes complicated.

  In particular, when sharing a shared key as pairing information as in Patent Document 1, when pairing information is deleted only in the storage unit of one of the wireless communication devices, a new pair is re-established when reconnecting thereafter. It is unclear whether ring information will be generated and re-paired, or whether the pairing information remaining in the storage unit of the other wireless communication device will be deleted. Such an unclear operation or control process may cause a malfunction.

  In such a configuration with complicated operations related to pairing and causes of troubles, user convenience is deteriorated. Even if the operation related to pairing is not a user operation but an automatic control process, the control process becomes complicated.

  Therefore, the present invention has been made in view of such circumstances, and an object thereof is to provide a wireless communication method and the like that improve the convenience of the user by simplifying the operation related to pairing.

In order to achieve the above object, a wireless communication method according to a first aspect of the present invention includes:
A notification step of notifying the application identification information of the own device and the OS identification information to another wireless communication device;
A storage step of storing device identification information of the other wireless communication device received from the other wireless communication device in the storage unit of the own device;
Obtaining the application identification information and the OS identification information stored in the storage unit of the other wireless communication device from the other wireless communication device when connecting to the other wireless communication device;
If the application identification information and OS identification information acquired from the other wireless communication device match the application identification information and OS identification information of the own device, the connection is maintained, and the application identification information and OS of the own device are maintained. A connection control step for disconnecting the connection if the identification information does not match;
It is characterized by including.

Function.

  The advertisement transmission control unit 121 transmits the advertisement to the central 200 via the wireless communication unit 110 and the antenna 111. The advertisement is transmitted at a regular timing according to the processing of the program or at a timing when a user operation occurs.

  Here, the advertisement is notification information for notifying the existence of itself and is information including device identification information. The device identification information is a device address or UUID (Universally Unique Identifier) of the peripheral 100.

  The connection establishment unit 122 establishes a connection with the central 200 by receiving a connection request from the central 200 via the antenna 111 and the wireless communication unit 110. By establishing this connection, data communication with the central 200 becomes possible.

  The connection disconnecting unit 123 receives a disconnection request for disconnecting the connection from the central 200 via the antenna 111 and the wireless communication unit 110, and disconnects the connection with the central 200.

  The application identification information acquisition unit 124 acquires application identification information from the central 200 via the antenna 111 and the wireless communication unit 110.

  Here, the application identification information is information for identifying an application (so-called application) held by the central 200. The application identification information is unique identification information generated using a random value generation API (Application Programming Interface) of the central 200 OS when an application is installed in the central 200. The application identification information is indicated by a hexadecimal number of 10 octets, for example. The application is an application for performing various communications with the peripheral 100 (that is, an electronic watch).

  The OS identification information acquisition unit 125 acquires OS identification information from the central 200 via the antenna 111 and the wireless communication unit 110.

  Here, the OS identification information is information for identifying the OS held by the central 200, and includes information indicating, for example, an android or iOS. Data transmitted / received between the peripheral 100 and the central 200 varies depending on the OS identification information. For example, the device identification information may be a device address or a UUID depending on the OS identification information. Therefore, the peripheral 100 communicates with the central 200 under communication conditions based on the acquired OS identification information.

  The application identification information acquired by the application identification information acquisition unit 124 and the OS identification information acquired by the OS identification information acquisition unit 125 are stored in the ROM 140 in association with each other.

  The identification information notification control unit 126 reads application identification information and OS identification information stored in the ROM 140. Then, the identification information notification control unit 126 transmits the application identification information and the OS identification information to the wireless communication unit 110 and notifies the central 200 thereof.

  The connection type notification control unit 127 transmits the connection type to the wireless communication unit 110 and notifies the central 200 of it.

  Here, the connection type is information indicating the purpose of the peripheral 100 connecting to the central 200. For example, when the pairing establishment process is performed, when data communication is performed by performing a normal connection, when automatic time adjustment is performed, or when time adjustment is caused by a user operation, the peripheral 100 searches the central 200. Different purposes depending on the case. The connection type is determined by the content of the user operation of the peripheral 100. For example, when the user presses the operation button of the peripheral 100 for a long time, the control unit 120 of the peripheral 100 determines the type for performing the pairing establishment process. When the user presses the operation button for a short time, the normal connection is made. Thus, the type of data communication is determined.

  The configuration of the peripheral 100 according to the present embodiment has been described above. Next, the configuration of the central 200 according to the present embodiment will be described.

  As shown in FIG. 3, the central 200 is connected to the bus line BL by a wireless communication unit 210, a control unit 220, a RAM 230, a ROM 240, an operation unit 250, a display unit 260, and a time measuring unit 270. And a clock signal generation unit 280.

  The wireless communication unit 210 includes, for example, an RF circuit, a BB circuit, an LSI, and the like. The wireless communication unit 210 performs wireless communication based on BLE with the peripheral 100, which is another wireless communication device, via the antenna 211.

  The control unit 220 is configured by a CPU, for example. The control unit 220 controls the overall operation of the central 200 by executing various programs stored in the ROM 240.

  The RAM 230 includes a volatile memory, and is used as a work area for temporarily storing data for the control unit 220 to perform various processes.

  The ROM 240 is configured by a nonvolatile memory such as a flash memory, and stores programs and data for the control unit 220 to control various functions.

  The operation unit 250 is configured by a touch panel or the like and is an interface that receives a user operation.

  The display unit 260 is configured by, for example, an LCD, an EL display, or the like, and displays an image according to the image data input from the control unit 220.

  The timer unit 270 is composed of a counter circuit that counts the number of pulses of the clock signal of its own device (central 200). The time measuring unit 270 measures time based on the number of pulses counted. In addition, the control unit 220 executes various controls at a timing based on the number of pulses counted by the time measuring unit 270.

  The clock signal generation unit 280 includes a crystal oscillator that generates a reference clock, a variable PLL that generates a clock signal having a desired frequency from the reference clock, and the like, and generates a clock signal of its own device (central 200). The frequency of this clock signal is controlled by changing the frequency division ratio of the variable PLL.

  Next, a functional configuration of the control unit 220 of the central 200 will be described. The control unit 220 includes an advertisement reception control unit 221, a connection request transmission control unit 222, a disconnection request transmission control unit 223, an identification information matching unit 224, an application identification information notification control unit 225, an OS identification information notification control unit 226, and a device identification. It functions as an information management unit 227 and a connection type determination unit 228.

  The advertisement reception control unit 221 causes the wireless communication unit 210 to receive an advertisement transmitted from the peripheral 100 based on the scan instruction. As a result, the central 200 recognizes the presence of the peripheral 100. As the user operation for the scan instruction, for example, activation of an application for using the service of the peripheral 100 can be considered. Further, the scan instruction is not limited to a user operation, and may be periodically performed after the application is activated.

  The connection request transmission control unit 222 causes the wireless communication unit 210 to transmit a signal indicating a connection request and requests the peripheral 100 to connect. The connection request is transmitted when connection is necessary after receiving the advertisement transmitted from the peripheral 100.

  The disconnection request transmission control unit 223 causes the wireless communication unit 210 to transmit a signal indicating a disconnection request, and issues a disconnection request to disconnect the connected peripheral 100. The disconnect request is transmitted, for example, when data communication with the connected peripheral 100 is completed or when a user disconnect operation is performed.

  The identification information matching unit 224 acquires application identification information and OS identification information notified from the peripheral 100 via the wireless communication unit 210 and the antenna 211. The identification information collating unit 224 collates whether the acquired application identification information and OS identification information match the application identification information and OS identification information of the own device (central 200) stored in the ROM 240.

  The application identification information notification control unit 225 reads out the application identification information of the application installed in the own device from the ROM 240. Then, the application identification information notification control unit 225 transmits the application identification information read from the ROM 240 to the wireless communication unit 210 and notifies the peripheral 100.

  The OS identification information notification control unit 226 reads the OS application identification information installed in the own apparatus from the ROM 240. Then, the OS identification information notification control unit 226 transmits the OS application identification information read from the ROM 240 to the wireless communication unit 210 and notifies the peripheral 100 of it.

  The device identification information management unit 227 manages device identification information of other wireless communication devices (peripherals 100) stored in the ROM 240.

  Specifically, the device identification information management unit 227 stores the device identification information included in the advertisement received from the peripheral 100 in the ROM 240. The device identification information management unit 227 also includes application identification information and OS identification information acquired from the peripheral 100 by the identification information matching unit 224, and application identification information and OS identification information of the own device (central 200) stored in the ROM 240. Is determined not to match, the device identification information of the peripheral 100 stored in the ROM 240 is deleted.

  The connection type determination unit 228 determines what purpose the connection type received from the peripheral 100 indicates. The control unit 220 executes subsequent control processing according to the determination result.

  Next, a pairing establishment process between the peripheral 100 and the central 200 will be described with reference to FIG.

  This process is executed when the user performs a predetermined operation. The predetermined operation is, for example, that the user turns on the communication function based on Bluetooth of the peripheral 100 with the operation unit 150, the user starts the application of the central 200 with the operation unit 250, and displays a new connection screen (pairing establishment) on the display unit 260. For example, an operation screen for performing processing).

  First, the control unit 120 of the peripheral 100 transmits an advertisement to the central 200 (step S101).

  The control unit 220 of the central 200 executes a scan (Step S201), and receives an advertisement transmitted from the peripheral 100 (Step S202). The control unit 220 of the central 200 stores the device identification information of the peripheral 100 included in the advertisement in the ROM 240.

  When the advertisement is received, the control unit 220 of the central 200 causes the display unit 260 to display an operation screen for accepting a user operation as to whether or not new registration is performed. Here, the control unit 220 of the central 200 determines whether or not the received user operation is a new registration (step S203).

  When the control unit 220 of the central 200 determines that the received user operation is not a new registration (step S203; No), the control unit 220 of the central 200 skips the subsequent processes (steps S204 to S208). Then, the pairing establishment process ends. In this case, since the control unit 220 of the central 200 does not transmit a connection request to the peripheral 100, the control unit 120 of the peripheral 100 also skips the subsequent processing (step S102 to step S105) and performs pairing establishment processing. finish.

  When the control unit 220 of the central 200 determines that the received user operation is a new registration (step S203; Yes), the control unit 220 of the central 200 transmits a connection request to the peripheral 100 (step S204). ).

  The control unit 120 of the peripheral 100 receives the connection request transmitted from the central 200 and establishes a connection (step S102).

  When the connection is established, the control unit 120 of the peripheral 100 and the control unit 220 of the central 200 perform service discovery (steps S103 and S205). As a result, subsequent processing can be executed.

  When the service discovery is finished, the control unit 120 of the peripheral 100 notifies the central 200 of the connection type (step S104). The connection type is a type determined based on the above-described predetermined operation content (for example, whether or not the operation button is pressed for a long time) that is an opportunity for the pairing establishment process.

  The control unit 220 of the central 200 receives the connection type notified from the peripheral 100 (step S206).

  Here, the control unit 220 of the central 200 determines whether or not the received connection type is a type for performing the pairing establishment process (step S207).

  When it is determined that the received connection type is not the type for performing the pairing establishment process (step S207; No), the control unit 220 of the central 200 skips the next process (step S208) and ends the pairing establishment process. . In this case, since the control unit 220 of the central 200 does not transmit application identification information and OS identification information to the peripheral 100, the control unit 120 of the peripheral 100 also skips the next process (step S105) and performs pairing. The establishment process is terminated.

  When it is determined that the received connection type is a type for performing pairing establishment processing (step S207; Yes), the control unit 220 of the central 200 notifies the peripheral 100 of application identification information and OS identification information (step S208). ).

  The control unit 120 of the peripheral 100 acquires the application identification information and OS identification information notified from the central 200 and stores them in the ROM 140 (step S105). Although the subsequent processing is omitted due to the limitation shown in the figure, the control unit 120 of the peripheral 100 notifies the central 200 that the application identification information and the OS identification information are stored, and the central 200 receives the notification. To do. Thereafter, control processing or communication corresponding to the connection type is performed between the central 100 and the peripheral 200. As a result, the pairing establishment process ends.

  Next, reconnection processing of the peripheral 100 and the central 200 described above will be described with reference to FIG. The reconnection process is a process for performing reconnection between the peripheral 100 and the central 200 after performing the pairing establishment process. This process is executed in response to a user operation or a periodic automatic control process.

  When the reconnection process is started, the control unit 220 of the central 200 periodically performs scanning (step S401). Here, when the control unit 120 of the peripheral 100 transmits the advertisement (step S301), the control unit 220 of the central 200 receives it by regular scanning (step S402).

  When receiving the advertisement, the control unit 220 of the central 200 transmits a connection request to the peripheral 100 (step S403). The control unit 120 of the peripheral 100 receives the connection request transmitted from the central 200 and establishes a connection (step S302).

  Thereafter, the control unit 120 of the peripheral 100 reads out the application identification information and the OS identification information stored in the ROM 140 and notifies the central 200 (step S303). The control unit 220 of the central 200 receives the application identification information and the OS identification information notified from the peripheral 100 (step S404).

  Here, the control unit 220 of the central 200 collates the application identification information and OS identification information acquired from the peripheral 100 with the application identification information of the application installed in its own device (central 200) and the OS identification information of the OS. Or not (step S405).

  When it is determined that the application identification information and the OS identification information match (step S405; Yes), the connection between the peripheral 100 and the central 200 is maintained. Then, the control unit 220 of the central 200 requests a connection type from the peripheral 100. The control unit 120 of the peripheral 100 that has received the connection type request notifies the central 200 of the connection type (step S304). The control unit 220 of the central 200 receives the connection type notified from the peripheral 100 (step S407). Thereafter, control processing or communication according to the connection type is performed between the central 100 and the peripheral 200 (steps S305 and S408).

  When it is determined that the application identification information and the OS identification information do not match (step S405; No), the control unit 220 of the central 200 transmits a disconnection request to the peripheral 100 to disconnect the peripheral 100 and store it in the ROM 240. The device identification information of the peripheral 100 being deleted is deleted (step S406).

  Thereafter, the control unit 120 of the peripheral 100 and 220 of the central 200 return to steps S301 and S401 and repeat the above-described reconnection processing.

  As described above, the control unit 220 of the central 200 notifies the peripheral 100 of the application identification information of its own device in step S208 of the pairing establishment process. Further, the control unit 220 of the central 200 stores the device identification information of the peripheral 100 received from the peripheral 100 in the ROM 240 in step S202 of the pairing establishment process.

  On the other hand, the control unit 120 of the peripheral 100 receives the application identification information of the central 200 from the central 200 and stores it in the ROM 140 in step S105 of the pairing establishment process.

  According to this configuration, in order to establish pairing between the peripheral 100 and the central 200, the peripheral 100 stores the application identification information and OS identification information of the central 200, and the central 200 stores the device identification information of the peripheral 100. Pairing is established. Therefore, it is not necessary to generate information such as a shared key in pairing establishment and share it between the peripheral 100 and the central 200.

  The control unit 120 of the peripheral 100 notifies the central 200 of the application identification information and the OS identification information stored in the ROM 140 in step S303 of the reconnection process for connecting to the central 200. If the identification information and the OS identification information do not match, the connection between the peripheral 100 and the central 200 is disconnected, and the central 200 deletes the device identification information of the peripheral 100 stored in the ROM 240.

  According to this configuration, for example, when the peripheral 100 establishes pairing with the central 200 and then establishes pairing with another central (not shown), the application identification information and OS identification information of the central 200 stored in the ROM 140 are stored. It is updated to the application identification information and OS identification information of the other central (not shown). When the peripheral 100 tries to reconnect to the central 200 again after that, the central 200 deletes the device identification information of the peripheral 100 stored in the ROM 240.

  Therefore, the user does not need to perform an operation for canceling the pairing of the peripheral 100 and the central 200. Further, the peripheral 100 can establish pairing with another central (not shown) without performing an operation for canceling the pairing between the peripheral 100 and the central 200.

  Further, according to this configuration, in the two wireless communication devices that share the shared key as pairing information, reconnection or pairing establishment is performed with the pairing information deleted only in the storage unit of one of the wireless communication devices. As in the case where it is performed, an unclear operation or control process is not required, and there is no cause for the occurrence of problems associated with the unclear operation or control process.

  Thus, according to the peripheral 100 and the central 200 of the present embodiment, it is possible to simplify the operation related to pairing and improve the convenience for the user.

  This is the end of the description of the embodiment. However, the above embodiment is merely an example. Therefore, the specific configurations and processing contents of the peripheral 100 and the central 200 are not limited to those described in the above embodiment. Hereinafter, modifications of the embodiment will be described.

(Modification)
In the above embodiment, the pairing establishment process and the reconnection process are executed by the control unit 120 of the peripheral 100 and the control unit 220 of the central 200. However, the peripheral 100 and the central 200 may each include a plurality of control units, and the plurality of control units may cooperate to execute the pairing establishment process and the reconnection process. That is, the advertisement transmission control unit 121, the connection establishment unit 122, the connection disconnection unit 123, the application identification information acquisition unit 124, the OS identification information acquisition unit 125, the identification information notification control unit 126, and the connection type notification control unit 127 The control unit may be a separate control unit, or each operation may be performed separately. Also, the advertisement reception control unit 221, the connection request transmission control unit 222, the disconnection request transmission control unit 223, the identification information collation unit 224, the application identification information notification control unit 225, the OS identification information notification control unit 226, and the device identification information management unit 227 and connection type determination unit 228 may be a single control unit, or each control unit may be provided separately to perform each operation.

  In the above embodiment, in step S105 of the pairing establishment process, the control unit 120 of the peripheral 100 stores the acquired OS identification information in the ROM 140. In step S303 of the reconnection process, the control unit 120 of the peripheral 100 notifies the OS identification information to the central 200, and the central 200 also determines whether or not the acquired OS identification information matches the OS identification information of the central 200. Judgment.

  However, the present invention is not limited to such a form. The peripheral 100 may be configured to store only application identification information and not OS identification information in the pairing establishment process. The central 200 may be configured to determine only whether the acquired application identification information matches the application identification information of the central 200 in the reconnection process. In other words, the notification of the OS identification information from the central 200 to the peripheral 100 is necessary for the subsequent communication, but it is arbitrary whether to notify the OS identification information for other purposes.

  In the above embodiment, the peripheral 100 and the central 200 store the acquired data in the ROM 140 and the ROM 240, respectively. However, the present invention is not limited to such a configuration. The peripheral 100 and the central 200 may be configured to store the acquired data in the RAM 130 or the RAM 230 instead of the ROM 140 and the ROM 240. That is, the storage destination may be anything as long as it is a storage unit such as RAM or ROM.

  In the above embodiment, the peripheral 100 and the central 200 are configured to execute the pairing establishment process when the user performs a predetermined operation. However, there is no need for such a user operation as a trigger. For example, when the central 200 receives an advertisement from the peripheral 100, the central 200 matches the device identification information of the peripheral 100 included in the advertisement with any of the device identification information stored in the ROM 240. It may be configured to determine whether or not the pairing establishment process is executed when there is no match.

  In the above-described embodiment, the peripheral 100 and the central 200 that perform wireless communication with each other based on BLE are illustrated as an example of a wireless communication device. However, the present invention is not limited to a wireless communication device that performs wireless communication based on BLE. For example, the present invention may be a wireless communication device that performs wireless communication based on Wi-Fi (registered trademark), ZigBee (registered trademark), or the like.

  Further, the peripheral 100 and the central 200 according to the present invention may realize the functions of the peripheral 100 and the central 200 by, for example, a computer executing a program regardless of the wireless communication apparatus. A program for realizing the functions of the peripheral 100 and the central 200 includes a USB (Universal Serial Bus) memory, a CD-ROM (Compact Disc-Read Only Memory), a DVD (Digital Versatile Disc), and an HDD (Hard Disc Drive). Or the like, or may be downloaded to a computer via a network.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to the specific embodiment which concerns, This invention includes the invention described in the claim, and its equivalent range It is. Hereinafter, the invention described in the scope of claims of the present application will be appended.
