  Here, in the fields 181 and 182, a telephone number and address information of the wired terminal 21 are registered in advance. In the field 183, the address information of the wireless terminal 22 is registered only when there is a wireless terminal 22 that has a parent-child relationship with the wired terminal 21. When a parent-child relationship is established between the wired terminal 21 and the wireless terminal 22, the wired terminal 21 becomes a parent device, and the wireless terminal 22 becomes a child device.

  And the main control part 19 controls each part 11-18 of the independent apparatus 1 centralizedly.

  Specifically, when the main control unit 19 receives call data from the external line network 5 via the external line IF unit 11, the communication control unit 13, the router unit 15, and the GW unit 14, the main control unit 19 refers to the parent-child information storage unit 18. Then, the address information of the wired terminal 21 to which the call data receiving number is assigned is acquired. Then, the call data and the acquired address information are passed to the call control unit 16. In response to this, the call control unit 16 performs incoming processing in cooperation with the main control unit 19, and establishes a voice path (call path) between the wired terminal 21 specified by the address information and the call data source.

  When the main control unit 19 receives call data from the wired terminal 21 via the extension IF unit 12, the communication control unit 13, the router unit 15, and the GW unit 14, it passes this call data to the call control unit 16. . In response to this, the call control unit 16 performs a calling process in cooperation with the main control unit 19 and sets a voice path between the wired terminal 21 and the destination of the call data.

  Further, as shown in the figure, the main control unit 19 includes a parent-child information registration unit 191, an address transmission unit 192, and a retry transmission unit 193. Using these units 191-193, the wired terminal 21 and the wireless terminal 22 are provided. Perform parent-child relationship setting process.

  FIG. 4 is a flowchart for explaining the parent-child relationship setting process of the main device 1.

  When the parent-child information registration unit 191 receives a parent-child setting request from the wired terminal 21 via the extension IF unit 12, the communication control unit 13, the router unit 15, and the GW unit 14 (YES in S101), the parent-child information registration unit 191 Time is acquired, and this is stored as an arrival time of the parent-child setting request in a memory or the like (not shown) in association with the address information of the wired terminal 21 (S102).

  When the parent-child information registration unit 191 receives a parent-child setting request from the wireless terminal 22 via the extension IF unit 12, the communication control unit 13, the router unit 15, and the GW unit 14 (YES in S103), the clock unit 17 The current time is acquired from this, and this is associated with the address information of the wireless terminal 22 and stored in a memory (not shown) or the like as the arrival time of the parent-child setting request (S104).

  Now, if the parent-child information registration unit 191 receives a parent-child setting request from both the wired terminal 21 and the wireless terminal 22 (YES in S105), the wired-terminal 21 and the wireless terminal 22 are referred to by referring to a memory or the like not shown. It is checked whether or not there is only one arrival time stored (S106).

  When there are a plurality of arrival times stored in a memory (not shown) for at least one of the wired terminal 21 and the wireless terminal 22 (NO in S106), the parent-child information registration unit 191 sends a retry request to the retry transmission unit 193. Instruct to send. In response to this, the retry transmission unit 193 sends a retry request for prompting the wired terminal 21 whose arrival time is registered in the memory or the like (not shown) to retransmit the parent-child setting request, The data is transmitted from the extension IF unit 12 via the router unit 15 and the communication control unit 13 (S107).

  Here, when the retry request is transmitted to the plurality of wired terminals 21, each wired terminal 21 is transmitted such that the retry request is transmitted to each wired terminal 21 at an interval from a predetermined time of S 108 described later. The transmission timing of the retry request for is shifted. Thereafter, the parent-child information registration unit 191 clears the correspondence information between the arrival time and the address information stored in a memory (not shown) and returns to the start.

  On the other hand, when the arrival time stored in a memory (not shown) is only one for each of the wired terminal 21 and the wireless terminal 22 (YES in S106), the parent-child information registration unit 191 The time difference between the arrival time of the wireless terminal 22 and the arrival time of the wireless terminal 22 is obtained, and it is checked whether or not the time difference is within a predetermined time (for example, 2 seconds) (S108).

  If it is not within the predetermined time (NO in S108), the parent-child information registration unit 191 instructs the retry transmission unit 193 to transmit a retry request.

  In response to this, the retry transmission unit 193 sends a retry request for prompting the wired terminal 21 to retransmit the parent-child setting request via the GW unit 14, the router unit 15, and the communication control unit 13. Transmission is performed from the IF unit 12 (S109). Thereafter, the parent-child information registration unit 191 clears the correspondence information between the arrival time and the address information stored in a memory (not shown) and returns to the start.

  On the other hand, if it is within the predetermined time (YES in S108), the process proceeds to S110.

  In S110, the parent-child information registration unit 191 searches the record 180 from the parent-child information storage unit 18 using the address information of the wired terminal 21 whose arrival time is stored in a memory (not shown) as a key. Then, it is checked whether or not the address information of the wireless terminal 22 is registered in the field 183 of the searched record 180.

  If not registered, that is, if the parent-child relationship is not set for the wired terminal 21 whose arrival time is stored in a memory (not shown) or the like (NO in S110), the parent-child information registration unit 191 stores the parent-child information storage. From the unit 18, the record 180 in which the address information of the wireless terminal 22 whose arrival time is stored in a memory (not shown) is registered in the field 183 is searched. If such a record 180 can be searched, the address information is deleted from the field 183 of the record 180. The parent-child information registration unit 191 registers the address information of the wireless terminal 22 in which the arrival time is stored in a memory or the like (not shown) in the field 183 of the record 180 searched in S110. Then, the parent-child information registration unit 191 instructs the address transmission unit 192 to transmit an address.

  In response to this, the address transmitting unit 192 includes the cordless terminal 21 in which the address information is registered in the field 182 of the record 180 searched in S110, and the slave unit including the address information registered in the field 183 of the record 180. In addition to transmitting the information, the base unit information including the address information registered in the field 182 of the record 180 is transmitted to the wireless terminal 22 in which the address information is registered in the field 183 of the record 180 (S111). Thereafter, the parent-child information registration unit 191 clears the correspondence information between the arrival time and the address information stored in a memory (not shown) and returns to the start.

  In S110, when the address information of the wireless terminal 22 is registered in the field 183 of the searched record 180, that is, the parent-child relationship has already been set for the wired terminal 21 whose arrival time is stored in a memory or the like (not shown). In some cases (YES in S110), the parent-child information registration unit 191 determines whether the combination of the wired terminal 21 and the wireless terminal 22 whose arrival time is stored in a memory (not shown) has appeared within a predetermined time. If it has been determined and has already appeared, the number of appearances of the combination held in a memory or the like (not shown) is incremented by one. Then, it is checked whether or not the number of appearances of this combination has reached a predetermined value (for example, 3 times) or more (S112).

  In S112, when the number of appearances exceeds the predetermined value (YES in S112), the parent-child information registration unit 191 stores the arrival time from the parent-child information storage unit 18 in a memory (not shown) or the like. The record 180 whose address information is registered in the field 183 is searched. If such a record 180 can be searched, the address information is deleted from the field 183 of the record 180. Further, the parent-child information registration unit 191 stores the address information of the wireless terminal 22 registered in the field 183 of the record 180 searched in S110, and the address of the wireless terminal 22 whose arrival time is stored in a memory (not shown). Update to information.

  As will be described later, the parent-child setting request is output from each of the wireless terminal 22 and the wired terminal 21 when the placement state of the wireless terminal 22 on the wired terminal 21 changes from “placed” to “not placed”. Is done. For this reason, even in a terminal where the parent-child relationship does not match, the parent-child relationship can be automatically set by the user repeating the mounting operation a predetermined number of times.

  Then, the parent-child information registration unit 191 instructs the address transmission unit 192 to transmit an address. In response to this, the address transmitting unit 192 includes the cordless terminal 21 in which the address information is registered in the field 182 of the record 180 searched in S110, and the slave unit including the address information registered in the field 183 of the record 180. In addition to transmitting the information, the base unit information including the address information registered in the field 182 of the record 180 is transmitted to the wireless terminal 22 in which the address information is registered in the field 183 of the record 180 (S114). . Thereafter, the parent-child information registration unit 191 clears the correspondence information between the arrival time and the address information and the number of appearances of the combination stored in a memory (not shown) and returns to the start.

  On the other hand, when the number of coincidence appearances is less than the predetermined value in S112 (NO in S112), the parent-child information registration unit 191 has a parent-child relationship with the wired terminal 21 whose arrival time is stored in a memory (not shown). An already-set notification for notifying that it has been set is transmitted from the extension IF unit 12 via the GW unit 14, the router unit 15, and the communication control unit 13 (S113). Thereafter, the parent-child information registration unit 191 clears the correspondence information between the arrival time and the address information stored in a memory (not shown) and returns to the start.

  First, the placement state detection unit 22111 monitors the placement state on the wired terminal 21 based on a signal from a sensor provided in the wired terminal IF unit 2208 (S2201). If it is detected that the placement state has changed from “placement” to “non-placement” (YES in S2201), the placement state detection unit 22111 sends a parent-child setting request to the parent-child setting request unit 22112. Instruct to send.

Alternatively, the address information registered in the parent device information storage unit 2210 is updated (S2204). Then return to the start.

  Next, an example of parent-child relationship setting processing by the parent-child telephone system to which this embodiment is applied will be described.

  FIG. 10 illustrates an example of a parent-child relationship setting process when the parent-child relationship of the wired terminal 21 is not set when one wired terminal 21 and one wireless terminal 22 transmit a parent-child setting request within a predetermined time. FIG.

  When the user raises and lowers the wireless terminal 22 from the wired terminal 21 and performs a placement operation (S501), the wired terminal 21 changes the placement state of the wireless terminal 22 from “placed” to “not placed”. ”Is detected (S502), and using this as a trigger, a parent-child setting request is transmitted to the main apparatus 1 (S504). Similarly, the wireless terminal 22 detects that the placement state of the terminal 22 on the wired terminal 21 has changed from “placed” to “non-placed” (S503). A parent-child setting request is transmitted to 1 (S505).

  When the main apparatus 1 receives a parent-child setting request from only one of the wired terminal 21 and the wireless terminal 22, the time difference between the arrival times of the parent-child setting requests from both terminals 21, 22 is within a predetermined time. Then, it is confirmed that the parent-child relationship of the wired terminal 21 is not set, and it is determined that the parent-child setting request for both the terminals 21, 22 is established, and the address information of the wireless terminal 22 is changed to only the address information of the wired terminal 21. Registration is performed so as to be associated (S506). Then, the slave unit information including the address information of the wireless terminal 22 is transmitted to the wired terminal 21 (S507), and the master unit information including the address information of the wired terminal 21 is transmitted to the wireless terminal 22 (S508).

  In response to this, the wired terminal 21 registers the address information included in the slave unit information received from the main device 1 as the address information of the wireless terminal (slave unit) 22 having a parent-child relationship with the own terminal 21 ( S509). Further, the wireless terminal 22 registers the address information included in the parent device information received from the main device 1 as the address information of the wired terminal (parent device) 21 having a parent-child relationship with the own terminal 22 (S510).

  FIG. 11 illustrates an example of a parent-child relationship setting process in a case where the parent-child relationship of each wired terminal 21 is not set when a plurality of wired terminals 21 and a plurality of wireless terminals 22 transmit a parent-child setting request within a predetermined time. FIG.

  When each user raises and lowers the wireless terminal 22 from the wired terminal 21 and performs a placement operation (S601), each wired terminal 21 changes the placement state of the wireless terminal 22 to the own terminal 21 from “placed”. It is detected that it has changed to “non-placed” (S602), and using this as a trigger, a parent-child setting request is transmitted to the main apparatus 1 (S604). Similarly, each wireless terminal 22 detects that the placement state of its own terminal 22 on the wired terminal 21 has changed from “placed” to “not placed” (S603). A parent-child setting request is transmitted to the device 1 (S605).

  Then, when receiving the parent-child setting request from the plurality of wired terminals 21 and the plurality of wireless terminals 22 within a predetermined time, the main device 1 determines that the parent-child setting request has not been established (S606). Then, the main device 1 transmits a retry request for prompting retransmission of the parent-child setting request to each wired terminal 21 at least at the predetermined time interval (S607).

  Upon receiving the retry request, each wired terminal 21 prompts the user to place the wireless terminal 22 on the terminal 21 (S608). In response to this, when each user raises and lowers the wireless terminal 22 from the wired terminal 21 and performs a placement operation (S609), each wired terminal 21 has the placement state of the wireless terminal 22 on its own terminal 21 " A change from “placed” to “non-placed” is detected (S610), and triggered by this, a parent-child setting request is transmitted to the main apparatus 1 (S612). Similarly, each wireless terminal 22 detects that the placement state of its own terminal 22 on the wired terminal 21 has changed from “placed” to “not placed” (S611). A parent-child setting request is transmitted to the device 1 (S613).

  When the main apparatus 1 receives a parent-child setting request from only one of the wired terminal 21 and the wireless terminal 22 within a predetermined time, the time difference between the parent-child setting request arrival times of both terminals 21 and 22 is within a predetermined time. And that the parent-child relationship of the wired terminal 21 is not set, it is determined that the parent-child setting request for both the terminals 21 and 22 is established, and the address information of the wireless terminal 22 is changed to only the address information of the wired terminal 21. Registration is performed so as to be associated with each other (S614). Then, the slave unit information including the address information of the wireless terminal 22 is transmitted to the wired terminal 21 (S615), and the master unit information including the address information of the wired terminal 21 is transmitted to the wireless terminal 22 (S616).

  Each wired terminal 21 registers the address information included in the slave unit information received from the main device 1 as the address information of the wireless terminal (slave unit) 22 having a parent-child relationship with the own terminal 21 (S617). Each wireless terminal 22 registers the address information included in the parent device information received from the main device 1 as the address information of the wired terminal (parent device) 21 having a parent-child relationship with the own terminal 22 (S618). .

  FIG. 12 illustrates an example of a parent-child relationship setting process when the parent-child relationship of the wired terminal 21 is already set when one wired terminal 21 and one wireless terminal 22 transmit a parent-child setting request within a predetermined time. FIG.

  When the user raises and lowers the wireless terminal 22 from the wired terminal 21 and performs a placement operation (S701), the wired terminal 21 changes the placement state of the wireless terminal 22 from “placed” to “not placed”. ”Is detected (S702), and using this as a trigger, a parent-child setting request is transmitted to the main apparatus 1 (S704). Similarly, the wireless terminal 22 detects that the placement state of the terminal 22 on the wired terminal 21 has changed from “placed” to “non-placed” (S703), and using this as a trigger, the main device A parent-child setting request is transmitted to 1 (S705).

  When main apparatus 1 receives the parent-child setting request from only one of each of wired terminal 21 and wireless terminal 22, whether the time difference between the arrival times of the parent-child setting requests from both terminals 21, 22 is within a predetermined time. Confirm whether or not. When the time difference between the arrival times of the parent-child setting requests from both terminals 21 and 22 is within a predetermined time, it is further confirmed whether or not the parent-child relationship of the wired terminal 21 is not set. Here, since the parent-child relationship of the wired terminal 21 has been set, it is determined that the parent-child setting request for both the terminals 21, 22 has not been established (S706). Then, the main device 1 transmits an already-set notification indicating that the parent-child relationship has been set to the wired terminal 21 (S707). In response to this, the wired terminal 21 uses the wireless terminal 22 to reset the parent-child relationship by the fact that the wireless terminal 22 is erroneously placed on the wired terminal 21 and the current combination of the wired terminal 21 and the wireless terminal 22. A message notifying that it is necessary to repeat the mounting operation is output (S708).

  In response to this, when the user raises and lowers the wireless terminal 22 from the wired terminal 21 and performs a placement operation (S709), the wired terminal 21 indicates that the placement state of the wireless terminal 22 on its own terminal 21 is “placement”. ”Is changed to“ non-placed ”(S710), and with this as a trigger, a parent-child setting request is transmitted to the main apparatus 1 (S712). Similarly, the wireless terminal 22 detects that the placement state of the terminal 22 on the wired terminal 21 has changed from “placed” to “non-placed” (S711). A parent-child setting request is transmitted to 1 (S713).

  When main apparatus 1 receives the parent-child setting request from only one of each of wired terminal 21 and wireless terminal 22, whether the time difference between the arrival times of the parent-child setting requests from both terminals 21, 22 is within a predetermined time. Confirm whether or not. When the time difference between the arrival times of the parent-child setting requests from both terminals 21 and 22 is within a predetermined time, it is further confirmed whether or not the parent-child relationship of the wired terminal 21 is not set. Here, since the parent-child relationship of the wired terminal 21 has already been set, it is determined that the parent-child setting request for both the terminals 21, 22 has not been established, and the processing of S706 to S713 is repeated.

  When the determination that the parent-child setting request is not established is repeated a predetermined number of times for the same combination of the wired terminal 21 and the wireless terminal 22, the main apparatus 1 determines that the parent-child setting request is established and updates the set parent-child relationship ( S714). Then, the slave unit information including the address information of the wireless terminal 22 is transmitted to the wired terminal 21 (S715), and the master unit information including the address information of the wired terminal 21 is transmitted to the wireless terminal 22 (S716).

  The wired terminal 21 registers the address information included in the slave device information received from the main device 1 as the address information of the wireless terminal (slave device) 22 having a parent-child relationship with the own terminal 21 (S717). Further, the wireless terminal 22 registers the address information included in the parent device information received from the main device 1 as the address information of the wired terminal (parent device) 21 having a parent-child relationship with the own terminal 22 (S718).

  As a result, as shown in FIG. 13B, the address information “192.168.10.13” is deleted from the field 183 of the record 180 in which the telephone number “14” is registered in the field 181. Further, the address information registered in the field 183 of the record 180 in which the telephone number “10” is registered in the field 181 is updated from “192.168.10.11” to “192.168.10.13”. .

  The embodiment of the present invention has been described above.

  In the present embodiment, each of the wired terminal 21 and the wireless terminal 22 transmits a parent-child setting request to the main apparatus 1 in response to a change in placement state. For this reason, when setting the parent-child relationship, there is no need to send and receive signals (signals) between the wired terminal 21 and the wireless terminal 22. Therefore, according to the present embodiment, it is possible to set and manage the parent-child relationship without providing a special interface for transmitting and receiving signals between the wired terminal 21 and the wireless terminal 22.

  In the present embodiment, when the main device 1 receives a parent-child setting request from a plurality of wired terminals 21 and a plurality of wireless terminals 22 within a predetermined time, each of the plurality of wired terminals 21 Send retry requests at different times. When the wired terminal 21 receives a retry request from the main device 1, the wired terminal 21 prompts the user to perform a placement operation. In this way, in this embodiment, even when a parent-child setting request is transmitted from a plurality of wired terminals 21 and a plurality of wireless terminals 22 within a predetermined time, the parent-child relationship of each wired terminal 21 is set.

  In the present embodiment, when the main apparatus 1 receives a parent-child setting request from one wired terminal 21 and one wireless terminal 22 within a predetermined time, the parent-child relationship of the wired terminal 21 is already set. In this case, an already set notification is transmitted to the wired terminal 21. Then, when the wired terminal 21 receives the already set notification from the main device 1, the wired terminal 21 notifies the user that it has been erroneously placed and that it is necessary to repeat the placement operation to change the parent-child relationship. When the situation of receiving the parent-child setting request within a predetermined time is repeated a predetermined number of times for the same combination of the wired terminal 21 and the wireless terminal 22, the main device 1 selects a child device having a parent-child relationship with the wired terminal 21. Update to this wireless terminal 22. By doing in this way, in this Embodiment, with respect to the wired terminal 21 in which the parent-child relationship has been set, this operation is performed by a simple operation of repeating the placement operation of the wireless terminal 22 that is not in a parent-child relationship with the wired terminal 21. The parent-child relationship of the wired terminal 21 can be updated.

  In addition, this invention is not limited to said embodiment, Many deformation | transformation are possible within the range of the summary. For example, each configuration of the main device 1, the wired terminal 21, the wireless terminal 22, and the wireless AP 3 is implemented by an integrated logic IC such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA). Alternatively, it may be executed by software by a computer such as a DSP (Digital Signal Processor) or a PC (Personal Computer).

  Further, in the present embodiment, in the wired terminal 21, an example in which the placement state detection unit 21111 detects the placement state of the wireless terminal 22 on the own terminal 21 by a sensor provided in the wireless terminal IF unit 2108 is taken as an example. Explained. However, the present invention is not limited to this. For example, the placement state detection unit 21111 may detect the placement state of the wireless terminal 22 on the terminal 21 by monitoring the amount of power supplied to the wireless terminal IF unit 2108 of the power supply control unit 2109.

  Similarly, in the present embodiment, in the wireless terminal 22, a case where the placement state detection unit 22111 detects the placement state of the terminal 22 on the wired terminal 21 by a sensor provided in the wired terminal IF unit 2208. Explained as an example. However, the present invention is not limited to this. For example, the placement state detection unit 22111 may detect the placement state of the terminal 22 on the wired terminal 21 by monitoring the power supply amount from the wired terminal IF unit 2208 of the power supply control unit 2209.

  FIG. 14 is a diagram for explaining a modification of the wireless terminal IF unit 2108 and the power supply control unit 2109 of the wired terminal 21 and the wired terminal IF unit 2208 and the power supply control unit 2209 of the wireless terminal 22.

  As illustrated, in the wired terminal 21, the wireless terminal IF unit 2108 has power supply terminals 21082 and 21083 for supplying power to the wireless terminal 22. In addition, the power control unit 2109 measures a power supply 21091 that supplies power to the power supply terminals 21082 and 21083, a resistor 21095 inserted in the power supply line of the power supply 21091, and a current value flowing through the power supply line of the power supply 21091. It has a current meter 21093, a voltage meter 21094 that measures the voltage value between the power supply terminals 21082 and 21083, and a power supply controller 21092 that adjusts the power supplied to the power supply 21091.

  In the configuration as described above, the power supply controller 21092 controls the supply power of the power supply 21091 based on the measured values of the current meter 21093 and the voltage meter 21094, and outputs these measured values to the placement information detection unit 21111. And the mounting information detection part 21111 detects the mounting state to the own terminal 21 of the radio | wireless terminal 22 based on these measured values. When the current value of the power supply line is equal to or less than a predetermined value, it is considered that the power supply terminals 21082 and 21083 are open. Further, when the voltage value between the power supply terminals 21082 and 21083 is less than or equal to a predetermined value, it is considered that some abnormality has occurred in the wireless terminal 22 and the power input terminals 22082 and 22083 of the wireless terminal 22 are short-circuited. In such a case, it is determined that the placement state is “non-placement”. Then, when the current value of the power supply line is within a predetermined range and the voltage value between the power supply terminals 21082 and 21083 is within the predetermined range, it is determined that the mounting state is “mounted”.

  In the wireless terminal 22, the wired terminal IF unit 2208 includes power input terminals 22082 and 22083 that are connected to the power supply terminals 21082 and 21803 of the wired terminal 21 and input power from the wired terminal 21. The power control unit 2209 includes a voltage meter 22092 that measures a voltage value between the power input terminals 22082 and 22083, a battery 22091 that stores power input to the power input terminals 22082 and 22083, a power input terminal 22082, and a battery. And a diode 22093 inserted between 22091.

  In the configuration as described above, the power control unit 2209 monitors the charge state of the terminal 22 based on the measurement value of the voltage meter 22092. Further, the measurement value is output to the placement information detection unit 22111. And the mounting information detection part 22111 detects the mounting state to the wired terminal 21 of the own terminal 22 based on this measured value. A change occurs in the measured value of the voltage meter 22092 between when the power input terminals 22082 and 22083 are opened and when a voltage is applied to the power input terminals 22082 and 22083. Therefore, the mounting state of the terminal 22 on the wired terminal 21 is detected based on the measured value of the voltage meter 22092.

  In the present embodiment, the main device 1 transmits a retry request to the wired terminal 21. However, the present invention is not limited to this.

The already set notification may be transmitted to at least one of the wired terminal 21 and the wireless terminal 22. Note that when the already-set notification is transmitted to the wireless terminal 22, the erroneous placement notification unit 21115 of the wired terminal 21 is provided in the wireless terminal 22 in the same manner. Further, when the already-set notification is not transmitted to the wired terminal 21, the erroneous placement notification unit 21115 may be omitted from the wired terminal 21.

  In the present embodiment, the placement state detection unit 21111 of the wired terminal 21 and the placement state detection unit 22111 of the wireless terminal 22 are configured so that the placement state of the wireless terminal 22 on the wired terminal 21 is “placement”. The change to “non-placement” is detected, and using this as an opportunity, the parent-child setting request units 21112 and 22112 are instructed to transmit a parent-child setting request. However, the present invention is not limited to this. The placement state detection unit 21111 of the wired terminal 21 and the placement state detection unit 22111 of the wireless terminal 22 have changed the placement state of the wireless terminal 22 on the wired terminal 21 from “non-placed” to “placed”. This may be detected, and using this as an opportunity, the parent-child setting request units 21112 and 22112 may be instructed to transmit a parent-child setting request.

  In the present embodiment, when the main device 1 receives a parent-child setting request from a plurality of wired terminals 21 and a plurality of wireless terminals 22 within a predetermined time, the main apparatus 1 is different from the plurality of wired terminals 21. Retry request is sent at the timing. However, the present invention is not limited to this.

Any device may be used as long as it transmits a retry request that can prompt the user to perform a placement operation at different timings.

  For example, the reminder timing is included in the retry request, and the reminder timing is made different for each wired terminal 21. Then, the main device 1 transmits a retry request to each wired terminal 21, and each wired terminal 21 performs a placement operation on the user based on the reminder timing included in the retry request received from the main device 1. Prompt. Alternatively, the main device 1 transmits a retry request to each wired terminal 21, and each wired terminal 21 that has received the retry request from the main device 1 arbitrarily adjusts the prompting timing for prompting the user to place the device. Good.

  In the present embodiment, the wireless terminal 22 is connected to the wired terminal 21 having a parent-child relationship with the wireless terminal 22 via the extension network 4 and the wireless AP 3. However, the present invention is not limited to this.
