  The headset 10, the mobile phone 30, and the wristwatch 50 are each configured to be connectable to the same communication network via short-range wireless communication. The configuration of the communication network is, for example, a configuration in which the mobile phone 30 serves as a gateway to the network, and the headset 10 and the wristwatch 50 are multi-connected to the communication network around the mobile phone 30. For example, in a Bluetooth (registered trademark) piconet connection, the mobile phone 30 is a master and the headset 10 and the watch 50 are slaves.

  In such a connection form, even if the headset 10 is turned off and the headset 10 is disconnected from the communication network, the mobile phone 30 and the wristwatch 50 form a communication network and data communication is possible between the two. It is said. Further, even when the wristwatch 50 is disconnected from the communication network, the mobile phone 30 and the headset 10 constitute a communication network so that voice data can be exchanged between the two. A state in which data communication is possible by connecting to such a communication network is called a state in which a communication link is established.

  In FIG. 2, the data block diagram showing a part of data stored in the memory | storage part of the wristwatch 50 is shown.

The storage unit (nonvolatile memory 58, RAM 51b provided in the microcomputer 51, etc.) provided in the wristwatch 50 stores the following data.
That is, in the data storage areas 58a and 58b of the nonvolatile memory 58, one or a plurality of headsets to be connected to the communication network (for example, the first headset “HS1”, the second headset “HS2”, etc.) Device identifiers (for example, device addresses uniquely added for each device) are stored, and whether or not the one or more headsets are connected to the communication network is stored in the data storage areas 51ba and 51bb of the RAM 51b. A connection flag indicating is stored.

  The device addresses stored in the storage areas 58a and 58b are, for example, set and input by the user through operation input of the operation unit 59 of the wristwatch 50, or data via short-range wireless communication from another computer or the mobile phone 30. The user inputs settings through communication. The connection flags for the storage areas 51ba and 51bb are set by the CPU of the microcomputer 51 as internal information.

  In addition, the storage unit of the wristwatch 50, the storage unit of the headset 10, and the storage unit of the mobile phone 30 are preliminarily set with information such as authentication information and encryption key for connecting to the communication network and performing data communication. .

  Next, three operation examples of the electronic system configured as described above will be described.

[First operation example]
FIG. 3 is a sequence diagram showing the flow of processing for establishing a communication link between the mobile phone 30 and the headset 10 by operating the wristwatch 50 and making a call.

  In the first operation example, first, a communication link between the mobile phone 30 and the wristwatch 50 is established (state S1), and a state in which the first headset (HS1) 10 is not joined to the communication network is an initial state. In such a state, the mobile phone 30 does not automatically execute a calling process for joining a new device to the communication network or a search process for a device that can participate in the communication network. Only when an execution request for these processes is made by an operation input or data communication via 43, the above-described calling process or search process is executed. With such a setting, power consumption is reduced.

  Here, when the user turns on the power switch 19 to join the headset 10 to the communication network (step J1), the microcomputer 11 of the headset 10 operates to communicate via short-range wireless communication. A process for searching for a call to the network is executed (step J2).

  In this state, the user can operate the mobile phone 30 to execute a calling process for causing the headset 10 to participate in the communication network. However, such operations may be difficult, for example, when the mobile phone 30 is hidden in a bag or the like, or when the mobile phone 30 is not in a state where it can be held in the hand. Therefore, in this embodiment, it is possible for the headset 10 to participate in the communication network simply by operating the wristwatch 50 without the user operating the mobile phone 30.

  That is, when it is difficult for the user to operate the mobile phone 30, the user operates the operation unit 59 of the wristwatch 50 to connect, for example, the first headset 10 registered in the wristwatch 50 in advance to the communication network. (Step J3). Then, the information P0 including the calling command and the identifier (for example, device address A) of the designated first headset 10 is transmitted from the wristwatch 50 to the mobile phone 30 via the short-range wireless communication. This processing constitutes a link request unit.

  When the mobile phone 30 receives the call command and the device address A information P0, the mobile phone 30 starts call processing for causing the device with the device address A to participate in the communication network based on these (step J4). The calling process is realized when the mobile phone 30 broadcasts, for example, by short-range wireless communication and makes a connection request to the device having the device address A.

  On the other hand, since the headset 10 is performing a search process for a call at this time, the headset 10 receives a connection request from the mobile phone 30 and performs a response process in response thereto. Then, a connection authentication process or the like is performed between the two, and the headset 10 is connected to the communication network (state S2). Even when the connection operation in step J3 is first performed and then the power on operation of the headset 10 in step J1 is performed thereafter, the connection processing is similarly performed between the mobile phone 30 and the headset 10, and the head The set 10 can be connected to a communication network.

  When the headset 10 is connected to the communication network, an HS1 connection notification P1 indicating that the first headset 10 (HS1) is connected from the mobile phone 30 to the wristwatch 50 is then transmitted. When the wristwatch 50 receives the HS1 connection notification P1, the microcomputer 51 of the wristwatch 50 performs a control operation based on the reception of the connection notification P1, and the notification unit 60 performs vibration, beep sound, light emission output, and the like. At the same time, the HS1 connection notification is displayed on the display unit 54 of the wristwatch 50 (step J5: link state notification means). The user can surely recognize that the headset 10 can be used by the notification operation and the connection notification display.

  At this time, the CPU in the microcomputer 51 sets an effective value as the connection flag information of HS1 in the data storage area 51ba of the RAM 51.

  In this state, for example, when the incoming call signal P2 is sent from the base station 70 to the mobile phone 30, an incoming call operation is performed on the mobile phone 30 and the incoming call alert information P3 is sent to the wristwatch 50 via short-range wireless communication. Sent. As a result, the wristwatch 50 performs an incoming call alerting operation by driving the alerting unit 60 and the display output (step J6). Here, when the user receives an incoming call notification operation and performs a receiving operation via the operation unit 59 (step J7), an incoming call command P4 is sent from the wristwatch 50 to the mobile phone 30. The microcomputer 31 executes incoming call response processing, and processing for receiving and calling is started (step J8).

  At this time, since the mobile phone 30 and the headset 10 are in a state where a communication link has been established, a voice bus is formed by short-range wireless communication (state S3), and call processing can be performed in the headset 10 (step S3). J9). Although illustration is omitted, after that, when the call of the mobile phone 30 is disconnected from the other party or the call is disconnected by the operation of the wristwatch 50, the call processing of the mobile phone 30 is ended. The configuration of the audio bus formed between the headset 10 and the mobile phone 30 is also released.

  Next, it is assumed that the user turns off the power switch 19 by determining that the headset 10 is not used for a while, for example (step J10). Then, the communication for connection confirmation performed at a predetermined cycle is interrupted between the mobile phone 30 and the headset 10, whereby the control operation of the microcomputer 31 of the mobile phone 30 is executed and the communication with the headset 10 is performed. The communication link is released (state S4). Further, at this time, the microcomputer 31 of the mobile phone 30 transmits an HS1 release notification P5 indicating that the connection of the first headset 10 is released to the wristwatch 50 via the communication network.

  When the HS1 release notification P5 is received by the wristwatch 50, the microcomputer 51 of the wristwatch 50 performs a control process to drive the notification unit 60 and to display the connection release information via the display unit 54. Is performed (step J11: link state notification means). As a result, the user can reliably recognize that the disconnection of the headset 10 has been completed. At this time, in the data storage area 51ba of the RAM 51 in the wristwatch 50, an invalid value is set as the connection flag information of the HS1, and the connection release information is stored.

[Second operation example]
FIG. 4 is a sequence diagram showing the flow of processing when a wristwatch 50 is later joined to the communication network between the mobile phone 30 and the headset 10.

  In the second operation example, the wristwatch 50 includes a state in which a communication link is established between the mobile phone 30 and the headset 10 (state S11), while the short-range wireless communication function of the wristwatch 50 is turned off. Is the initial state when not connected to the communication network. In this state, for example, in order to connect the watch 50 to the communication network, the user operates the operation unit 59 to turn on the short-range wireless communication function (step J12) and operates the mobile phone 30. Then, it is assumed that the calling process for causing the wristwatch 50 to participate in the communication network is started (step J14).

  When such an operation is performed, a calling process and a calling search process are executed between the mobile phone 30 and the wristwatch 50, and the wristwatch 50 responds to a connection request for the mobile phone 30 via short-range wireless communication. Then, a connection authentication process or the like is performed between the two, and the wristwatch 50 is connected to the communication network (state S12).

  In the mobile phone 30, processing steps for notifying the wristwatch 50 of the current connection status of the headset 10 when the wristwatch 50 newly joins the communication network are executed by a control program executed by the CPU of the microcomputer 31. It is like that. By this processing step, the microcomputer 31 of the mobile phone 30 transmits notification information P11 indicating the current connection status of the headset 10 to the wristwatch 50 when the wristwatch 50 newly joins the communication network as described above. . In the example of FIG. 4, since the first headset 10 is in a connected state, HS1 connection presence notification information P <b> 11 is transmitted to the wristwatch 50.

  Here, when no headset is connected, notification information indicating no connection is transmitted to the wristwatch 50, and the wristwatch 50 recognizes the state of no headset being connected. In addition, when no headset is connected, the wristwatch 50 may be configured to recognize the state of no headset connection by not transmitting any connection notification information.

  When the wristwatch 50 is notified of the headset connection status, the microcomputer 51 of the wristwatch 50 drives the notification section 60 to perform the notification operation, and the headset connection status notified to the display section 54 of the wristwatch 50. Is displayed (step J15). At this time, the CPU of the microcomputer 51 sets a flag value corresponding to the connection information of the headset in the data storage areas 51ba and 51bb of the RAM 51. In the example of FIG. 4, based on the HS1 connection presence notification information P11, a valid value is stored in the HS1 connection flag of the storage area 51ba, and an invalid value is stored in the HS2 connection flag of the storage area 51bb.

  Through the processing as described above, the mobile phone 30, the headset 10, and the wristwatch 50 are connected to the same communication network. Thereafter, for example, when the incoming call signal P2 is transmitted from the base station 70 to the mobile phone 30, processing similar to the processing after the transmission of the signal P2 in the processing sequence of FIG. 3 is realized.

[Third operation example]
FIG. 5 is a sequence diagram showing an example of the flow of processing when a mail is received by the mobile phone while the headset 10, the wristwatch 50, and the mobile phone are connected to the communication network. An example of an image diagram showing the state of the mail text displayed on the display unit 54 of the wristwatch 50 during this processing is shown.

  In the third operation example, for example, similarly to the first operation example shown in FIG. 3, the mobile phone 30 wristwatch 50 and the headset 10 are first processed by the processing in steps J1 to J5 and the transmission and reception of data P0 and P1. Shows a case where a mail is received from the base station 70 to the mobile phone 30 in a state where is connected to the communication network.

  When the mobile phone 30, the wristwatch 50, and the headset 10 are connected to the communication network, respectively, when mail arrives from the base station 70 to the mobile phone 30 and the mail data P 21 is transmitted to the mobile phone 30, first, The cellular phone 30 automatically receives the mail data P21 (step J21) and transfers the same mail data P22 as the received data to the wristwatch 50 (step J22: mail information transmitting means). The mail transfer process may be configured to be switched on / off according to the operation setting of the mobile phone 30, for example.

  When the mail data P22 is transmitted to the wristwatch 50, the microcomputer 51 of the wristwatch 50 performs a process of receiving the mail data P22. When the reception of the mail data P22 is completed, the notification unit 60 is activated to notify the user of the mail reception. A notification operation is performed. Further, the mail text is displayed and output on the display unit 54 based on the received mail data (step J23: mail display means). By such processing, the user can know the reception of the mail, and further, by looking at the display unit 54 of the wristwatch 50, a part of the mail text (sender, subject, mail main part) as shown in FIG. Display of the head of the). However, when the mail text is long, the mail text in the range 54B outside the display unit 54 of the wristwatch 50 cannot be confirmed immediately unless a complicated scroll operation is performed.

  When the user confirms a part of the mail text and wants to read the entire text of the mail, the user performs an operation of performing reading through the operation unit 59 of the wristwatch 50 (step J24). Then, the reading command P23 is transmitted from the wristwatch 50 to the mobile phone 30, and the microcomputer 31 of the mobile phone 30 executes the voice reading processing of the mail sentence transferred earlier based on the reading command P23 (step J25: E-mail reading means). That is, the mail sentence is divided into words, voice data for each word is created, and these are connected to synthesize voice data for reading a mail sentence. Then, this audio data output process is performed.

  If the communication link between the mobile phone 30 and the headset 10 is established at this time, an audio bus is formed by short-range wireless communication (state S3), and audio data is transferred to the headset 10 via this audio bus. Is done. As a result, voice output for reading out the mail text is performed in the headset 10 (step J26). The user can confirm the contents of the whole mail text by voice by listening to the voice reading voice through the headset 10 by the display on one screen of the display unit 54 of the wristwatch 50.

  As described above, according to the electronic system and the wristwatch 50 of this embodiment, the cellular phone 30 is operated by operating the wristwatch 50 and performing the connection operation with the headset 10 (step J3 in FIG. 3). The communication link between the mobile phone 30 and the headset 10 can be established without doing so. In addition, when the headset 10 joins the communication network, when the connection is released, or when the watch 50 joins the communication network, the notification unit 60 of the watch 50 operates and the display Since the connection status of the headset 10 is displayed on the unit 54, the user can reliably recognize the connection status of the headset 10 by these.

  Therefore, for example, even if the mobile phone 30 is in a bag or cannot be held, if the headset 10 and the wristwatch 50 are worn, the wristwatch 50 is operated to operate the mobile phone 30 and the headset. Even if the communication link with the mobile phone 10 is established to enable a call via the headset 10 or the power switch 19 of the headset 10 is frequently switched, the headset 10 and the mobile phone 30 are It is possible to check the state of the communication link of

  Further, even when an e-mail is received by the mobile phone 30, it is possible to confirm the mail reception and a part of the mail content by the operation of the wristwatch 50, and if necessary, without operating the mobile phone 30. It is also possible to listen to the contents of the mail text by voice through the headset 10. Therefore, even when the mobile phone 30 is in a bag and is not held in the hand, the e-mail received by the mobile phone 30 can be appropriately confirmed by voice.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, in the above embodiment, a connection request for the designated headset 10 is made by operating the wristwatch 50, but a connection request for an arbitrary headset may be made without designation. The form in which the wristwatch 50 notifies the user of the connection status of the headset can be changed as appropriate, for example, only the notification operation or only the display output.

  Moreover, in the said embodiment, although the wristwatch 50 was illustrated as an arm mounting | wearing type terminal, it is good also as a terminal without a clock function. In the above embodiment, Bluetooth communication is exemplified as short-range wireless communication. However, for example, Wibree (Wybree: a short-range wireless standard advocated by a Finnish company.) And ZigBee (ZigBee: short-range wireless communication for home appliances) Various power-saving short-range wireless communications such as (standard) can also be applied, and other short-distance wireless communications of the original standard and other wireless communications other than short-range wireless communications can also be applied. In addition, the details and the like shown in the above embodiment can be appropriately changed without departing from the spirit of the invention.
