The presence or absence of a target connection may be detected.

Next, the operation of the telephone system according to the present embodiment will be described with reference to FIGS.
In the present embodiment, data corresponding to the key telephone handset 20 to which the wireless handset 40 determined to be erroneously placed is used as the redial data to be transmitted.

First, with reference to FIG. 4, the operation when a redial operation is performed by another parent in which the wireless slave unit is erroneously placed in the telephone system according to the present embodiment will be described. FIG. 4 is a sequence diagram showing the operation (separate parent redial) of the telephone system according to the present embodiment.
When the user places (misplaces) the wireless slave device 40A on the parent device (separate parent) 30B that is not set as a pair with this child device (step S100), the parent device control unit 39 of the separate parent 30B. Detects that an arbitrary wireless slave device has been placed based on the output from the placement detector 38, and starts charging the battery of the wireless slave device placed by the power feeding portion 37. The device 10 is notified (step S101). In response to the charging start notification from the separate parent 30B, the control unit 15 of the main device 10 starts a timer in order to identify the wireless slave device placed on the separate parent 30B (step S102).

When the wireless slave device control unit 49 of the wireless slave device 40A detects that the wireless slave device is placed on any parent device based on the output from the state detection unit 45, the wireless slave device control unit 49 is supplied from the parent device on which the charging unit 44 is placed. The battery 43 starts to be charged with power, and the wireless I / F unit 41 and the wireless I / F unit 32 of the parent device (former parent) 30A set as a pair with the wireless slave device 40A via the wireless line are wirelessly connected. By performing communication, the detection of being placed is regarded as on-hook and notified (step S103).
In response to the on-hook notification from the wireless slave unit 40A, the master unit control unit 39 of the former master unit 30A and the extension I / F unit 13 of the main apparatus 10 via the extension line 17 from the extension I / F unit 31 and data By communicating, the on-hook is notified to the main device 10 (step S104).

  When a predetermined time elapses after receiving the charging start notification from the separate parent 30B, the control unit 15 of the main device 10 selects any of the placed on the separate parent 30B based on the on-hook notification received within the predetermined time. Identify the wireless slave unit. Here, since the on-hook notification is received from the wireless slave device 40A within a predetermined time, the control unit 15 of the main device 10 specifies that the wireless slave device 40A is placed on the separate parent 30B (step S105). .

  When the user performs a redial operation using the key input unit 35 of the separate parent 30B in a state where the wireless slave unit 40A is erroneously placed on the separate parent 30B as described above (step S106), the master unit control unit of the separate parent 30B. 39 notifies the main device 10 of the redial operation (step S107).

  The control unit 15 of the main apparatus 10 has already detected in step S105 that the wireless slave device 40A is erroneously placed on the separate parent 30B. For this reason, when receiving the redial notification from the separate parent 30B, the control unit 15 of the main device 10 redials the original parent 30A in which the user who misplaces the wireless slave device 40A is set as a pair with the wireless slave device 40A. Therefore, it is determined that the redial operation is performed by the separate parent 30B, and the redial data of the original parent 30A is retrieved from the redial buffer 16A of the storage unit 16 of the main device 10 (step S108).

An example of the redial buffer 16A is shown in FIG. FIG. 5 is a schematic diagram of the redial buffer 16A.
The redial buffer 16A is composed of a set of a predetermined number of records in which at least redial data, that is, transmission history data and data indicating the operation source of the transmission operation are stored in association with each other. With this configuration, it is possible to identify whether each outgoing call history is from the parent device 30 or the child device 40. For example, in the redial buffer 16A shown in FIG. 5, "1234" is dialed by the former parent 30A as the latest outgoing call history, and "2345" is dialed by the slave unit 40A as the previous outgoing call history. . Such a redial buffer 16A is provided for each pair of the parent device 30 and the child device 40 set as a pair.
Further, when the handset 40A is off-hook after inputting the preset dial on the base unit 30A, the redial buffer 16A registers the same dial in the records of the original base 30A and the handset 40A. For example, in FIG. 5, since the same dial “7777” is registered in the records of the parent device 30 </ b> A and the child device 40 </ b> A, this means that the preset dial “7777” has been input.

  When the redial buffer 16A is searched and the latest outgoing history “1234” of the former parent 30A is detected, the control unit 15 of the main apparatus 10 captures the telephone line 11 by the external line I / F unit 12, and the detected dial is connected to the network. (Step S109).

  Thus, according to the present embodiment, when a redial operation is performed from another parent when the wireless slave unit is erroneously placed on another parent, the redial data of the original parent of the wireless slave unit is selected. Since the transmission is performed, it is possible to prevent a situation in which the user is confused, for example, an unintended destination dial is transmitted.

  In the present embodiment, the redial buffer 16A not only stores the redial data of the master unit 30 and the slave unit 40 as shown in FIG. 5 but also stores the redial data of the master unit 30 and the slave unit 40, for example. Various redial buffers can be freely applied as appropriate, including those that store data without distinction, those that store only one redial data, and those that store only one redial data of the master unit 30 and the slave unit 40. can do.

Next, with reference to FIG. 6, description will be given of an operation in the case where a redial operation is performed with a wireless slave device erroneously placed on another parent in the telephone system according to the present embodiment. FIG. 6 is a sequence diagram showing the operation (wireless handset redial) of the telephone system according to the present embodiment.
In FIG. 6, the wireless slave device 40A is erroneously placed on the separate parent 30B, and the erroneous placement detection method is the same as in the case of FIG. 4 described above (steps S100 to S105). Therefore, in the following description, the same placement detection method as that of FIG.

  In a state where the wireless slave device 40A is erroneously placed on the separate parent 30B, when the user picks up the wireless slave device 40A from the separate parent 30B in order to make a call on the wireless slave device 40A (step S200), Based on the output from the placement detection unit 38, the base unit control unit 39 detects that the placed wireless slave unit has been picked up, and notifies the main device 10 of this fact (step S201). Further, when the wireless slave device control unit 49 of the wireless slave device 40A detects that the wireless slave device is picked up from any parent device based on the output from the state detection unit 45, the wireless I / F unit 41 via the wireless line By performing wireless communication with the wireless I / F unit 32 of the former parent 30A, detection of being picked up is regarded as off-hook and notified (step S202). In response to the off-hook notification from the wireless slave unit 40A, the master unit control unit 39 of the former master unit 30A and the extension I / F unit 13 of the main apparatus 10 via the extension line 17 from the extension I / F unit 31 and data By communicating, the off-hook is notified to the main apparatus 10 (step S203).

When the user performs a redial operation using the key input unit 48 of the wireless slave device 40A (step S204), the wireless slave device control unit 49 of the wireless slave device 40A performs the redial operation via the original parent 30A. (Step S205, 206).
In this case, the control unit 15 of the main apparatus 10 retrieves the redial data of the wireless slave unit 40A from the redial buffer 16A of the storage unit 16 (step S207), and when the latest outgoing call history is detected, the outside line I / F unit 12 The telephone line 11 is captured and the detected dial is transmitted to the network (step S208).
Here, as the redial buffer 16A, not only the redial data of the parent device 30 and the child device 40 as shown in FIG. 5 but stored separately, for example, the redial data of the parent device 30 and the child device 40 is not distinguished. Various redial buffers can be applied as appropriate, such as those storing one, storing only one redial data, and storing only one redial data of the master unit 30 and the slave unit 40 without distinction.

  Thus, according to the present embodiment, when a redial operation is performed from a wireless slave unit when the wireless slave unit is erroneously placed on another parent, the redial data of the wireless slave unit is selected and transmitted. Therefore, it is possible to prevent a situation in which the user is confused, for example, an unintended destination dial is transmitted.

  In the present embodiment, the redial buffer 16A stores the transmission history of the original parent 30A and the transmission history of the wireless slave device 40A separately. For this reason, in this embodiment, even if the dial operation is performed on the original parent 30A while the wireless slave device 40A is erroneously placed on the separate parent 30B, the transmission history and the wireless slave before the erroneous placement is performed. By selecting the transmission history of the machine 40A, more accurate redial transmission can be performed. This case can be realized by storing data such as time and detection of erroneous placement in the redial buffer 16A.

  Moreover, in this Embodiment, the control part 15 of the main apparatus 10 makes the latest transmission history of the former parent 30A the latest transmission history of the other parent 30B when the wireless slave device 40A is erroneously placed on the different parent 30B. The redial buffer 16A may be controlled so as to replace with. In this case, if a redial operation is performed from the parent 30B when the wireless slave device 40A is erroneously placed on the parent 30B, the control unit 15 of the main device 10 uses the redial data of the parent 30B as it is. . Then, since the redial data of the former parent 30A is transmitted to the network, the user is not confused as a result. This method is preferably applied when the wireless slave device 40A is erroneously placed on the separate parent 30B and the call is disconnected.

  In the present embodiment, the method for detecting erroneous placement is not limited to the method described above, and various methods can be applied as appropriate.

  In the present embodiment, the redial data recorded in the redial buffer 16A may record not only the outside line number but also the extension number. When the extension number is selected as the redial data, the control unit 15 of the main apparatus 10 controls the extension I / F unit 13 and sends the button telephone slave unit 20 corresponding to the extension number via the extension transmission path 17. call.
