With this short-range wireless communication function, when there is an incoming call or mail incoming to the mobile phone 10, incoming call data representing these incoming calls is transmitted from the mobile phone 10 to the wristwatch 40, thereby vibrating the wristwatch 40. Incoming call notification operations such as flashing of light emission and buzzer sound output are executed. Such an incoming call notification function is particularly useful when the mobile phone 10 is set in a silent mode and placed in a bag or the like.

  In addition, the mobile phone 10 according to the present embodiment has an offline mode that is a transmission / reception prohibition mode that prohibits transmission / reception of radio signals, as one of its operation modes, such as areas where use of radio waves is restricted. However, other additional functions of the mobile phone 10 that do not use radio waves without transmitting and receiving radio signals can be used. In addition, when the mobile phone 10 receives a radio wave restricted area signal indicating that the radio wave output area 60 has approached the use restricted area of the radio wave in cooperation with the radio wave restricted area signal generating device 60, It also has a function of automatically shifting to the offline mode. The radio wave restricted area signal generator 60 is installed at, for example, an entrance of a radio wave use restricted area such as a hospital.

  The mobile phone 10 is in wireless communication with a nearby base station at a predetermined cycle even in a standby state in which a telephone call or data communication via the mobile phone network is not performed. Thus, it is possible to recognize in which area the mobile phone 10 exists. As a result, when a call is made to the mobile phone 10 from another phone, a calling signal is transmitted to the mobile phone 10 from a nearby base station.

  In addition, the Bluetooth module 22 of the mobile phone 10 and the Bluetooth module 48 of the wristwatch 40 are both placed in a communicable range, and a connection request is issued to one of them, whereby authentication processing is executed by both of them, A communication link is established. When the communication link is established, it becomes possible to perform immediate data communication with each other. Also, in wireless communication via these Bluetooth modules 22 and 48, wireless signals are not transmitted / received only when data communication is performed, and even when data communication is not performed, every predetermined time interval. It is confirmed that the communication link is maintained by transmitting and receiving radio signals to each other.

  In the above-described offline mode of the mobile phone 10, not only transmission / reception of radio signals between the mobile phone 10 and the base station during a call or data communication, but also between the mobile phone 10 and the base station during no call or no communication. Wireless communication is also prohibited and cannot be executed. That is, when the mobile phone 10 is shifted to the offline mode, all the radio signal transmission / reception functions of the mobile phone 10 are stopped, while other additional functions that do not transmit / receive radio signals, The received email can be browsed.

And the wireless signal transmission / reception processing of the Bluetooth module 22 is prohibited. In addition, as described above, even when a radio signal indicating a radio wave restricted area is input from the outside while the mobile phone 10 is in the normal mode, the CPU 11 performs control based on the reception of the signal, and the operation of the mobile phone 10 is performed. The mode is automatically shifted to offline mode.

  The wristwatch 40 has a function of turning off the radio wave that completely stops transmission / reception of the wireless signal by the Bluetooth module 48 under the control of the CPU 41. When the radio wave off function is enabled, the communication link of the Bluetooth module 48 is released and the data communication is stopped, and a search packet for searching for a communication counterpart device is transmitted to the Bluetooth module 48 from the outside. However, it will not receive it or return a response to the search packet.

  Next, operations of the mobile phone 10 and the wristwatch 40 configured as described above will be described in detail based on flowcharts.

  FIG. 4 is a flowchart of the incoming call process executed by the CPU of the mobile phone.

  In mobile phone 10, in a normal mode for accepting incoming calls, when a call signal is received from the base station, CPU 11 starts the incoming call process of FIG. 4. When this process is started, first, the CPU 11 confirms the incoming call (step S1), and if the incoming call is confirmed, the incoming call is received by the short-range wireless communication via the Bluetooth modules 22 and 48 to the wristwatch 40. Data is transmitted (step S2).

  FIG. 5 is a flowchart of the offline mode on process executed by the CPU of the mobile phone.

  The CPU 11 of the mobile phone 10 starts the offline mode on process of FIG. 5 when the setting for switching to the offline mode is made based on the operation of the operation unit 14 by the user. When this process is started, first, the CPU 11 confirms the presence or absence of a communication link for short-range wireless communication between the wristwatch 40 and the mobile phone 10 (step S11). If the communication link is not established, the CPU 11 requests connection to the Bluetooth module 22. To establish a communication link for short-range wireless communication with the wristwatch 40 (step S12). Next, “radio wave off data” indicating a shift to the offline mode is transmitted to the wristwatch 40 by short-range wireless communication via the Bluetooth module 22 (step S13).

  After transmitting the radio wave off data, the communication link release command is sequentially issued to the Bluetooth module 22 to disconnect the short-range wireless communication with the wristwatch 40 (step S14), and the wristwatch 40 is set in the offline mode on the liquid crystal display unit 15. (Step S15), the RF transceiver circuit 20 and the Bluetooth module 22 are deactivated, and the input / output of radio signals is turned off (step S16). Thereby, the mobile phone 10 shifts to the offline mode.

  FIG. 6 is a flowchart of radio wave restricted area signal reception processing executed by the CPU of the mobile phone.

  When the CPU 11 of the mobile phone 10 receives a radio wave restricted area signal from the radio wave restricted area signal generating device 60 via the RF transmission / reception circuit 20 in the normal mode in which a telephone call can be received, the reception process of FIG. 6 is performed. Start. When this process is started, first, it is confirmed whether or not the radio wave restricted area signal has been received (step S21). If this signal reception cannot be confirmed, this process is terminated, but if this signal reception is confirmed, Processing for shifting to the offline mode in steps S22 to S27 is executed, and this reception processing is terminated. The processing in steps S22 to S27 is the same as the processing in steps S11 to S16 in FIG.

  FIG. 7 shows a flowchart of the reception process executed by the CPU of the wristwatch.

  In the wristwatch 40, the CPU 41 repeatedly executes the reception process of FIG. 7 at short time intervals. When this reception process is started, first, the CPU 41 determines whether or not incoming call data has been received from the mobile phone 10 by data communication via the Bluetooth module 48 (step S31). If the incoming call data has been received, the incoming call notification operation is performed by driving the vibration motor 50, the blinking drive of the light emitting diode 52, the buzzer output drive by the piezo element 54, and the like (step S32). On the other hand, if the incoming call data is not received, the process proceeds to the next step.

  Next, the CPU 41 of the wristwatch 40 determines whether or not “radio wave off data” indicating a shift to the offline mode is received from the mobile phone 10 by data communication via the Bluetooth module 48 (step S33). If “radio wave off data” has not been received, this reception process is terminated. If radio wave off data has been received, a communication link release command is issued to the Bluetooth module 48 and the mobile phone 10 is disconnected. Next, the short-range wireless communication is disconnected (step S34), and then the Bluetooth module 48 is deactivated so that wireless signals are not transmitted / received (step S35). Then, this reception process is terminated.

  When the mobile phone 10 receives a call or mail in the normal mode for accepting an incoming call by the control processing shown in the flowcharts of FIGS. 4 to 7, the incoming call data is received via the short-range wireless communication. It is sent from the mobile phone 10 to the wristwatch 40, whereby the incoming call notification operation is performed by the wristwatch 40.

  In addition, when the mobile phone 10 is shifted to the offline mode by operating the operation unit 14 of the mobile phone 10 or receiving a radio wave restricted area signal via the RF transmission / reception circuit 20 of the mobile phone 10, short-range wireless communication is performed. The radio wave off data is transmitted from the mobile phone 10 to the wristwatch 40 via the wireless phone, and thereafter, transmission / reception of a radio signal on the mobile phone 10 is prohibited. Transmission / reception is prohibited and is not executed. At this time, as shown in FIG. 8, a display indicating that the wristwatch 40 has shifted to the offline mode is displayed on the display unit of the mobile phone 10.

  As described above, according to the mobile phone system 1 of the embodiment of the present invention, when the mobile phone 10 shifts to the offline mode, the wristwatch 40 is automatically prohibited from using radio waves as in the offline mode. Therefore, there is an effect that the user does not have to operate the switch 44 of the wristwatch 40 each time to stop the function of using the radio wave.

  In addition, since the display indicating that the wristwatch 40 has shifted to the offline mode is displayed on the liquid crystal display unit 15 of the mobile phone 10, for example, when the user exits the radio wave use restricted area and cancels the offline mode of the mobile phone 10. In addition, the user can be alerted not to forget to cancel the offline mode of the wristwatch 40.
