  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).

  When the parent-child information registration unit 191 receives the parent-child setting request from both the wired terminal 21 and the wireless terminal 22 (YES in S105), the parent-child information registration unit 191 refers to the arrival time of a memory or the like (not shown) and wirelessly transmits from the wired terminal. The terminal arrival times are subtracted and the absolute value is obtained. Then, it is determined whether or not the difference value is received within a predetermined default value T1 seconds (for example, 0.5 seconds). (S106) All of the pair of wired terminals and wireless terminals received within T1 seconds are determined. The combination is temporarily stored in a memory not shown, and the number of times is incremented. Further, it is determined whether a predetermined N1 times (for example, twice) have been received from the same wired terminal and wireless terminal (S107). Further, it is determined whether there are a plurality of combinations of wired terminals and wireless terminals that have reached N1 times (S108).

  If there is a combination that has reached N1 times (YES 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 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 (S109).

  Here, when transmitting a retry request to the plurality of wired terminals 21, each wired terminal is configured such that the retry request is transmitted to each wired terminal 21 at least at a predetermined time T <b> 1 of S <b> 108 described later. The transmission timing of the retry request for 21 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, from the arrival time stored in the memory, both of which are not shown, if the combination of the wire terminal 21 and the radio terminal 22 reaches a predetermined N1 number was set (NO in S108), to S110 move on.

  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 that the combination of the wired terminal 21 and the wireless terminal 22 whose arrival time is stored in a memory (not shown) is a predetermined time T2 (> T1, for example, 6 seconds). ), The number of appearances of the combination held in a memory (not shown) or the like is incremented by one. Then, it is checked whether or not the number of appearances N2 of this combination has reached a predetermined value (for example, 3 times) or more (S112).

  In S112, when the appearance count N2 is equal to or greater than 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 in which the address information of 22 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 issued when the placement state of the wireless terminal 22 on the wired terminal 21 changes from “placed” to “not placed” or from “not placed” to “placed”. Are output from each of the wireless terminal 22 and the wired terminal 21. 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 placement operation a predetermined N2 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, in S112, when the number of coincidence appearance N2 is less than the predetermined value (NO in S112), the parent-child information registration unit 191 sends a parent-child to the wired terminal 21 whose arrival time is stored in a memory (not shown). An already-set notification for notifying that the relationship 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.

  In the present embodiment, the parent-child information registration unit 191 is illustrated if the parent-child setting request is received for a predetermined N1 times (for example, twice) from both the wired terminal 21 and the wireless terminal 22 within the predetermined time T1. When a pair of wired terminals and wireless terminals can be detected from the arrival times stored in all of the predetermined N1 times for each of the wired terminal 21 and the wireless terminal 22 with reference to a memory that is not connected, etc. The case where it is determined whether the setting request is established or not has been described as an example. However, the present invention is not limited to this. For example, the parent-child information registration unit 191 obtains a time difference between the arrival times of the plurality of wired terminals 21 and the arrival times of the plurality of wireless terminals 22 stored in a memory (not shown) or the like, and this time difference is the predetermined time T1. If it is within (for example, 0.5 seconds), the interval patterns of the arrival times from the wired terminal 21 and the wireless terminal 22 a predetermined N1 times (for example, 2 times) are compared, and the interval pattern is within a predetermined error range. The establishment / non-establishment of the parent-child setting request may be determined only when the combination of the wired terminal 21 and the wireless terminal 22 that match is a set of terminals.

The wired terminal IF unit 2208 includes a power input terminal for inputting power from the wired terminal 21 and a sensor for detecting a mounting state on the wired terminal 21.

  The power control unit 2209 controls the storage of electric power provided from the wired terminal 21 connected to the wired terminal IF unit 2208.

  The parent device information storage unit 2210 stores address information of the wired terminal 21 that has a parent-child relationship with the own terminal 22.

  The main control unit 2211 comprehensively controls each unit 2201 to 2210 of the own terminal 22.

  Specifically, when main controller 2211 receives a call instruction with a called number from the operator via operation panel 2204 and operation controller 2205, it passes this call instruction to call controller 2203. In response to this, the call control unit 2203 performs call processing in cooperation with the main control unit 2211, and communicates with the calling party specified by the called number via the wired terminal 21 having a parent-child relationship with the own terminal 22. Set the audio path.

  When the main control unit 2211 receives call data from the main apparatus 1 via the wireless IF unit 2201 and the communication control unit 2202 via the wired terminal 21 having a parent-child relationship with the own terminal 22, the main control unit 2211 receives the call data from the main device 1. 2203. In response to this, the call control unit 2203 performs incoming processing in cooperation with the main control unit 2211 and establishes a voice path between the call terminal and the call data source via the wired terminal 21 having a parent-child relationship. Set.

  When the main control unit 2211 receives a switching instruction from the operator via the operation panel 2204 and the operation control unit 2205, or via the wireless IF unit 2201 and the communication control unit 2202, When a switching instruction is received from the related wired terminal 21, data transmission / reception with the main apparatus 1 is started via the wired terminal 21.

  Further, as shown in the figure, the main control unit 2211 has a placement state detection unit 22111, a parent / child setting request unit 22112, and a parent device information registration unit 22113. Using these units 22111 to 22113, a parent / child setting request Process.

  FIG. 9 is a flowchart for explaining the parent-child setting request processing of the wireless terminal 22.

  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” or from “non-placement” to “placement” (YES in S2201), the placement state detection unit 22111. Instructs the parent-child setting request unit 22112 to transmit a parent-child setting request. In response to this, the parent-child setting request unit 22112 transmits a parent-child setting request including identification information indicating that the transmission source is a wireless terminal to the main apparatus 1 via the communication control unit 2202 and the extension IF unit 2201. (S2202) Then, the process returns to the start.

  Further, when the parent device information registration unit 22113 receives the parent device information from the main apparatus 1 via the wireless IF unit 2201 and the communication control unit 2202 (YES in S2203), the address information included in the parent device information Is registered in the parent device information storage unit 2210 as address information of the wired terminal 21 having a parent-child relationship with the own terminal 22. 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 shows a case where the parent-child relationship of the wired terminal 21 is not set when the situation where one wired terminal 21 and one wireless terminal 22 transmit the parent-child setting request within a predetermined time T1 is repeated N1 times. It is a sequence diagram for demonstrating the parent-child relationship setting process example in the case of being.

  When a plurality of users raise and lower the wireless terminals 22-1 and 22-2 from the wired terminals 21-1 and 21-2 and perform a placement operation (S501), the wired terminals 21-1 and 21-2. Detects that the placement state of the wireless terminals 22-1 and 22-2 on the own terminals 21-1 and 21-2 has changed from "placed" to "not placed" (S502, S503). In response to this, a parent-child setting request is transmitted to the main apparatus 1 (S504, S506). The main device 1 measures the parent device arrival time (S508). Similarly, in the wireless terminals 22-1 and 22-2, the placement state of the own terminals 22-1 and 22-2 on the wired terminals 21-1 and 21-2 is changed from “placed” to “not placed”. Each change is detected (S502, S503), and triggered by this, a parent-child setting request is transmitted to the main apparatus 1 (S505, S507). The main device 1 measures the arrival time of the child device (S508).

  Thereafter, the wired terminals 21-1 and 21-3 change the placement state of the wireless terminals 22-1 and 22-3 from their own terminals 21-1 and 21-3 from “non-placed” to “placed”, respectively. It is detected that they have changed almost simultaneously (S509, S510), and using this as a trigger, a parent-child setting request is transmitted to the main apparatus 1 (S511, S513). Main apparatus 1 measures the arrival time of the master unit (S515). Similarly, in the wireless terminals 22-1 and 22-3, the placement state of the own terminals 22-1 and 22-3 on the wired terminals 21-1 and 21-3 is changed from “non-placed” to “placed”. The change is detected (S509, S510), and triggered by this, a parent-child setting request is transmitted to the main apparatus 1 (S512, S514). The main device 1 measures the arrival time of the child device (S515).

  The main device 1 has a predetermined N1 times (for example, two times) when the main device 1 receives a parent-child setting request from each of the same wired terminal 21-1 and wireless terminal 22-1 within a predetermined time T1. When it is repeated, it is confirmed that the parent-child relationship of the wired terminal 21-1 is not set, it is determined that the parent-child setting request for both the terminals 21-1, 22-1 is established, and the address information of the wireless terminal 22-1 is obtained. Then, registration is performed so as to be associated only with the address information of the wired terminal 21-1 (S516). Then, the slave unit information including the address information of the wireless terminal 22-1 is transmitted to the wired terminal 21-1 (S517), and the master unit information including the address information of the wired terminal 21-1 is transmitted to the wireless terminal 22-1. Is transmitted (S518).

  In response to this, the wired terminal 21-1 receives the address information included in the slave device information received from the main device 1, and the wireless terminal (slave device) 22-1 having a parent-child relationship with the own terminal 21-1. Registration as address information (S519). Further, the wireless terminal 22-1 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 that has a parent-child relationship with the own terminal 22-1. (S520).

  FIG. 11 and FIG. 12 show the parent-child relationship of each wired terminal 21 when the situation in which the plurality of wired terminals 21 and the plurality of wireless terminals 22 transmit the parent-child setting request within a predetermined time T1 is repeated N1 times. It is a sequence diagram for demonstrating the example of a parent-child relationship setting process when is not set.

  When a plurality of users raise and lower the wireless terminals 22-1 and 22-2 from the wired terminals 21-1 and 21-2 and perform placement operations (S601), the wired terminals 21-1 and 21- 2 detects that the placement state of the wireless terminals 22-1 and 22-2 on the own terminals 21-1 and 21-2 has changed from “placement” to “non-placement” (S602, S603). In response to this, a parent-child setting request is transmitted to the main apparatus 1 (S604, S606). Similarly, in the wireless terminals 22-1 and 22-2, the placement state of the own terminals 22-1 and 22-2 on the wired terminals 21-1 and 21-2 is changed from “placed” to “not placed”. (S602, S603), and using this as a trigger, a parent-child setting request is transmitted to the main device 1 (S605, S607). The main device 1 measures the arrival time from the parent device and the child device. (S608).

  Thereafter, the placement status of the wireless terminals 22-1 and 22-2 on the own terminals 21-1 and 21-2 is changed from “not placed” to “placed”. It is detected that they have changed almost simultaneously (S609, S610), and using this as a trigger, a parent-child setting request is transmitted to the main apparatus 1 (S611, S613). Similarly, in the wireless terminals 22-1 and 22-2, the placement state of the own terminals 22-1 and 22-2 on the wired terminals 21-1 and 21-2 is changed from “not placed” to “placed”. (S609, S610), and using this as a trigger, a parent-child setting request is transmitted to the main device 1 (S612, S614). The main device 1 measures the arrival time from the parent device / child device. (S615).

  The main apparatus 1 receives a parent-child setting request from a plurality of sets of the same wired terminals 21-1 and 21-2 and a plurality of wireless terminals 22-1 and 22-2 within a predetermined time T1. Since there are a plurality of combinations of priority terminals and wireless terminals that have reached the number of times (for example, twice), it is determined that the parent-child setting request is not established (S616).

  The main apparatus 1 transmits to each of the wired terminals 21-1 and 21-2 a retry request that prompts retransmission of the parent-child setting request at least at the interval of the predetermined time T1 (S617, S619).

  Upon receiving the retry request, each of the wired terminals 21-1 and 21-2 prompts the user to place the wireless terminals 22-1 and 22-2 on the own terminals 21-1 and 21-2 (S618, S620). ). In response to this, when each user raises and lowers the wireless terminals 22-1 and 22-2 from the wired terminals 21-1 and 21-2 and performs a placement operation (S621), each wired terminal 21-1 and 21 is operated. -2 detects that the placement state of the wireless terminals 22-1 and 22-2 on the own terminals 21-1 and 21-2 has changed from "placed" to "not placed" (S622, S626). In response to this, a parent-child setting request is transmitted to the main apparatus 1 (S623, S627). Similarly, in the wireless terminals 22-1 and 22-2, the placement state of the own terminals 22-1 and 22-2 on the wired terminals 21-1 and 21-2 is changed from “placed” to “not placed”. (S622, S626), and using this as a trigger, a parent-child setting request is transmitted to the main apparatus 1 (S624, S628). The main device 1 measures the arrival time from the master / slave (S625, S629).

  Thereafter, the placement status of the wireless terminals 22-1 and 22-2 on the own terminals 21-1 and 21-2 is changed from “not placed” to “placed”. Each change is detected (S630, S639), and triggered by this, a parent-child setting request is transmitted to the main apparatus 1 (S631, S640). Similarly, in the wireless terminals 22-1 and 22-2, the placement state of the own terminals 22-1 and 22-2 on the wired terminals 21-1 and 21-2 is changed from “not placed” to “placed”. (S630, S639), and using this as a trigger, a parent-child setting request is transmitted to the main device 1 (S632, S641). The main device 1 determines the arrival time from the parent device / child device. Measure (S633, S642).

  Now, when the main apparatus 1 receives a parent-child setting request from only one of the wired terminal 21-1 and the wireless terminal 22-1 within a predetermined time T1, it is repeated a predetermined N1 times (for example, twice). After confirming that the parent-child relationship of the wired terminal 21-1 has not been set, it is determined that the parent-child setting request for both the terminals 21-1, 22-1 has been established, and the address information of the wireless terminal 22-1 is changed to the wired terminal 21. -1 so as to be associated only with the address information of -1 (S634). Then, the slave unit information including the address information of the wireless terminal 22-1 is transmitted to the wired terminal 21-1 (S635), and the master unit information including the address information of the wired terminal 21-1 is transmitted to the wireless terminal 22-1. (S636). Similarly, when a parent-child setting request is repeatedly received N1 times (for example, twice) from each one of the wired terminal 21-2 and the wireless terminal 22-2 within a predetermined time T1, the parent-child relationship of the wired terminal 21-2 Is determined to be unset, it is determined that the parent-child setting request for both the terminals 21-2 and 22-2 is established, and the address information of the wireless terminal 22-2 corresponds only to the address information of the wired terminal 21-2. Registration is made so that it is attached (S643). Then, the slave unit information including the address information of the wireless terminal 22-2 is transmitted to the wired terminal 21-2 (S644), and the master unit information including the address information of the wired terminal 21-2 is transmitted to the wireless terminal 22-2. (S645).

  Each of the wired terminals 21-1 and 21-2 uses the address information included in the slave unit information received from the main device 1 as a wireless terminal (slave unit) having a parent-child relationship with the own terminals 21-1 and 21-2. Registered as address information 22-1 and 22-2, respectively (S637, S646). Each of the wireless terminals 22-1 and 22-2 uses the address information included in the parent device information received from the main device 1 as a wired terminal (parent) having a parent-child relationship with the own terminals 22-1 and 22-2. Machine) 21-1 and 21-2 are registered as address information (S638, S647).

  FIG. 13 and FIG. 14 show the parent-child relationship of the wired terminal 21 when the situation where one wired terminal 21 and one wireless terminal 22 transmit a parent-child setting request within a predetermined time T1 is repeated N1 times. It is a sequence diagram for demonstrating the example of a parent-child relationship setting process when is already set.

  When a plurality of users raise and lower the wireless terminals 22-1 and 22-2 from the wired terminals 21-1 and 21-2 and perform a placement operation (S701), the wired terminals 21-1 and 21-2 are wirelessly connected. It is detected that the placement state of the terminals 22-1 and 22-2 on the own terminals 21-1 and 21-2 has changed from "placement" to "non-placement" (S702, S703). As a trigger, a parent-child setting request is transmitted to the main device 1 (S704, S706). Similarly, in the wireless terminals 22-1 and 22-2, the placement state of the own terminals 22-1 and 22-2 on the wired terminals 21-1 and 21-2 is changed from “placed” to “not placed”. Change is detected (S702, S703), and triggered by this, a parent-child setting request is transmitted to the main apparatus 1 (S705, S707). The main device 1 measures the arrival time from the master / slave (S708).

  Thereafter, the wired terminal 21-1 detects that the placement state of the wireless terminal 22-1 on the own terminal 21-1 has changed from “non-placed” to “placed” (S709). Then, a parent-child setting request is transmitted to the main apparatus 1 (S710). Similarly, the wireless terminal 22-1 detects that the placement state of the terminal 22-1 on the wired terminal 21-1 has changed from “non-placed” to “placed” (S709). As a trigger, a parent-child setting request is transmitted to the main device 1 (S711), and the main device 1 measures the arrival time from the parent device / child device (S712).

  Then, when the main device 1 receives a parent-child setting request from only one of the wired terminal 21-1 and the wireless terminal 22-1 within a predetermined time T1, it is repeated a predetermined N1 times (for example, twice). It is confirmed whether or not the parent-child relationship of the wired terminal 21-1 is not set. Here, since the parent-child relationship of the wired terminal 21-1 has been set, it is determined that the parent-child setting request for both the terminals 21-1, 22-1 has not been established (S713).

  The main apparatus 1 transmits an already-set notification indicating that the parent-child relationship has been set to the wired terminal 21-1 (S714). In response to this, the wired terminal 21-1 has a parent-child relationship based on the fact that the wireless terminal 22-1 is erroneously placed on the wired terminal 21-1, and the combination of the current wired terminal 21-1 and wireless terminal 22-1. Is reset, a message notifying that it is necessary to repeat the mounting operation of the wireless terminal 22-1 is output (S715).

  In response to this, when the user raises or lowers the wireless terminal 22-1 from the wired terminal 21-1 and performs a placement operation (S716), the wired terminal 21-1 is the own terminal 21- of the wireless terminal 22-1. 1 is detected to change from “placed” to “non-placed” (S717), and using this as a trigger, a parent-child setting request is transmitted to the main apparatus 1 (S718). Similarly, the wireless terminal 22-1 detects that the placement state of the own terminal 22-1 on the wired terminal 21-1 has changed from “placed” to “not placed” (S717). As a trigger, a parent-child setting request is transmitted to the main device 1 (S719), and the main device 1 measures the arrival time from the parent device / child device (S720).

  Thereafter, the wired terminal 21-1 detects that the placement state of the wireless terminal 22-1 on the own terminal 21-1 has changed from “non-placed” to “placed” (S721), and this is triggered. Then, a parent-child setting request is transmitted to the main apparatus 1 (S722). Similarly, the wireless terminal 22-1 detects that the placement state of the terminal 22-1 on the wired terminal 21-1 has changed from “non-placed” to “placed” (S721). As a trigger, a parent-child setting request is transmitted to the main device 1 (S723), and the main device 1 measures the arrival time from the parent device / child device (S724).

  Then, when the main device 1 receives a parent-child setting request from only one of the wired terminal 21-1 and the wireless terminal 22-1 within a predetermined time T1, it is repeated a predetermined N1 times (for example, twice). It is confirmed whether or not the parent-child relationship of the wired terminal 21-1 is not set. Here, since the parent-child relationship of the wired terminal 21-1 has been set, it is determined that the parent-child setting request for both the terminals 21-1, 22-1 has not been established, and the processing of S714 to S724 is repeated.

  The main apparatus 1 determines that the parent-child setting request is not established for a combination of the same wired terminal 21-1 and wireless terminal 22-1 within a predetermined time T2 (> T1, for example, 6 seconds). When the number of times is repeated, it is determined that the parent-child setting request is established, and the set parent-child relationship is updated (S725). Then, the slave unit information including the address information of the wireless terminal 22-1 is transmitted to the wired terminal 21-1 (S726), and the master unit information including the address information of the wired terminal 21-1 is transmitted to the wireless terminal 22-1. Is transmitted (S727).

  The wired terminal 21-1 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) 22-1 having a parent-child relationship with the own terminal 21-1. (S728). Further, the wireless terminal 22-1 uses 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) 21-1 having a parent-child relationship with the own terminal 22-1. Registration is performed (S729).

  Next, the transition of registered contents in the parent-child information storage unit 18 will be described. FIG. 15 is a diagram for explaining a transition example of registered contents in the parent-child information storage unit 18.

  In FIG. 15A, the wired terminal 21 (address: 192) assigned the telephone number “14” to the wired terminal 21 (address: 192.168.10.1) assigned the telephone number “10”. .168.10.4) is placed on the wireless terminal 22 (address: 192.168.10.13), the sequence shown in FIG. 12 is performed, and the telephone number “10” is The parent-child information of the assigned wired terminal 21 is updated.

  As a result, as shown in FIG. 15B, 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.

  Further, in the present embodiment, when the main apparatus 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 T1, it is repeated a predetermined plurality of N1 times. A retry request is transmitted to each of the plurality of wired terminals 21 at different timings. When each wired terminal 21 receives a retry request from the main device 1, the wired terminal 21 prompts the user to perform a placement operation. Thus, in the present embodiment, even when parent-child setting requests are transmitted from the plurality of wired terminals 21 and the plurality of wireless terminals 22 within the predetermined time T1, the parent-child relationship of each wired terminal 21 is set. be able to.

  Further, 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 T1, a predetermined number of times N1 are repeated. When the parent-child relationship of the wired terminal 21 has been set, 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 T2 (> T1) is repeated N2 times for the same combination of the wired terminal 21 and the wireless terminal 22, the main device 1 The child device in the parent-child relationship is updated 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, the parent-child setting request may be repeatedly received until it is detected that the parent-child setting request has been received from one wired terminal and one wireless terminal within the predetermined time T1. In this way, a set of wired terminals and wireless terminals that have made a parent-child setting request can be specified without fail, and thus a retry request can be completely eliminated. In addition, as long as the first parent-child setting request is not transmitted from a plurality of sets of wired terminals and wireless terminals, one set of wired terminals and wireless terminals can be identified for the first time. It may be determined whether or not it is established. In addition, when the first parent-child setting request is transmitted from a plurality of sets of wired terminals and wireless terminals, a retry request is sent to each of the plurality of wired terminals at different timings, but the wired terminal that has received the retry request is placed. By determining whether or not the parent-child setting request can be established in a single placement operation by causing the wired terminal and the wireless terminal to send the parent-child setting request again within a predetermined time T1 due to momentary interruption or interruption of the charging current to the wireless terminal. May be.

  Each configuration of the main device 1, the wired terminal 21, the wireless terminal 22, and the wireless AP 3 is executed in hardware by an integrated logic IC such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array). 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. 16 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.

  For example, the remind request is included in the retry request, and the prompt 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. By mounting a wireless interface on the wired terminal 21, the wireless terminal 22 may be directly connected to the wired terminal 21 having a parent-child relationship with the wireless terminal 22 via a wireless network. Alternatively, the wireless terminal 22 may be directly accommodated in the main apparatus 1 (connected without going through the wired terminal 21). That is, the main device 1 may switch the connection destination of the call path between the wired terminal 21 and the wireless terminal 22 having a parent-child relationship.

  In the present embodiment, the case where a wireless LAN is used for wireless communication of the wireless terminal 22 has been described. However, the present invention is not limited to this. A PHS or a mobile phone may be used for wireless communication of the wireless terminal 22.
