[Problems to be solved by the invention]
A wireless telephone used in such a telephone system is provided with a charging stand, that is, a mounting place for charging by placing a wireless slave unit on the base unit. Usually, the base unit is mounted when not in use. Although the wireless slave unit is placed at the location, since the wireless slave unit is wirelessly connected to the master unit, the wireless slave unit can be carried to a place some distance from the master unit as necessary.
Therefore, for example, when a user moves to another room according to the content of a call on the wireless slave unit, and the wireless slave unit is not placed on another master unit installed in the destination room Depending on the end of the call, the wireless slave device may be erroneously placed on the destination master device.
[0007]
In the conventional telephone system, when an erroneous placement of a wireless slave unit occurs, the main device of the telephone system is controlled on the assumption that each wireless slave unit is placed on a paired master unit. The following problems occur.
For example, in FIG. 7, a radio telephone A consisting of a master unit A and a radio slave unit A and a radio telephone B consisting of a master unit B and a radio slave unit B are connected to the main unit, and the radio slave unit A is a master unit. It is assumed that it is erroneously placed on the machine B (step 200).
In this state, when there is an individual incoming call from the network side to the wireless telephone B (step 201), the main unit notifies the incoming call to the base unit B corresponding to the wireless telephone B (step 202), and in response thereto, the base unit B Incoming call display is performed (step 203).
[0008]
Here, when the user picks up the handset of the parent device B, that is, the wireless slave device A erroneously placed on the parent device B in order to respond to the incoming call to the parent device B (step 210), The wireless slave device A detects an off-hook (step 211), and notifies the parent device A of the off-hook via a wireless line with the original parent device A (step 212).
In response to this, the main unit A notifies the main unit of the off-hook of the wireless sub unit A (step 213). In response to this notification, the main unit does not receive an incoming call to the radio telephone A. The off-hook at the machine A is determined as a call origination request, and one of the idle telephone lines is captured (step 214). When there is no available telephone line, or when there is one telephone line, a busy tone is notified from the main unit to the wireless slave unit A via the master unit A.
[0009]
Therefore, even if the user tries to respond to the incoming call to the main unit B and picks up the handset of the main unit B, that is, the wireless slave unit that is erroneously placed on the main unit B, the outside line transmission state or the busy state At the same time, there is a problem that the incoming call display on the main unit B is continued and the user cannot respond to the incoming call to the main unit B.
The present invention has been made to solve such problems, and an object of the present invention is to provide a telephone system capable of responding to an incoming call to a parent device by a wireless slave device erroneously mounted on the parent device. .

[0020]
The state detection unit 45 is realized as a known technique by a general switch such as a hook switch that operates mechanically by placing the wireless slave unit 40 on the base unit 30 or a photo interrupter that operates electrically. There is also an example, and the placement detection unit 38 may use the same switch.
Further, as the state detection unit 45, there is an example in which the electrical connection between the charging terminal 37A and the charging terminal 44A used for the charging operation is detected between the parent device 30 and the wireless slave device 40, and the placement detection unit 38 is also the same. The electrical connection may be detected.
[0021]
In this case, an amount of electricity that changes due to the electrical connection between the charging terminal 37A and the charging terminal 44A, for example, a current value or a voltage value is taken in from the power feeding unit 37 or the charging unit 44, and wirelessly connected to the parent device 30 according to the change.

When the battery 43 of the wireless slave device 40 is fully charged, the charging power from the master device 30 to the wireless slave device 40 becomes zero. Therefore, for example, by flowing a current of a predetermined value or more between the charging terminals 37A and 44A at all times, or by applying a predetermined potential, the electricity between the charging terminal 37A and the charging terminal 44A can be obtained even in a fully charged state. The presence or absence of a target connection may be detected.
[0022]
Next, the operation of the telephone system according to the present embodiment will be described with reference to FIG. 4 by taking, as an example, call processing to a parent device in an erroneous placement state. FIG. 4 is a sequence diagram showing the operation of the telephone system according to the present embodiment (call processing to the base unit in an erroneous placement state).
First, in a state where the user has mistakenly placed the wireless slave device 40A in the parent device 30B other than the parent device 30A set as a pair with the wireless slave device 40A in advance (step 100), the wireless telephone from the telephone line 11 is used. When there is an individual incoming call with 20B as the destination (step 101), the control unit 15 of the main apparatus 10 detects the individual incoming call based on a notification from the external line I / F unit 12. Then, the extension I / F unit 13 notifies the incoming call to the base unit 30B of the radio telephone 20B that is the destination via the extension transmission path 17 (step 102). Note that the fact that this base unit 30B is in an incoming call state is registered in the management information 16A of the storage unit 16.
[0023]
The base unit control unit 39 of the base unit 30B receives an incoming call notification from the main apparatus 10 via the extension I / F unit 31 and controls the voice processing unit 33 to output a ringing tone. The incoming call display is performed by controlling the LED and the LCD (step 103). In response to this, the user confirms the incoming call to the radio telephone 20B, and picks up the handset of the master unit 30B, in this case, the radio slave unit 40A (step 110). As a result, the wireless slave unit control unit 49 of the wireless slave unit 40A detects an off-hook state based on the output from the state detection unit 45 (step 111), and that effect is transmitted from the wireless I / F unit 41 via the wireless line. 30A is notified (step 112).
[0024]
The base unit control unit 39 of the base unit 30A receives the off-hook notification from the radio slave unit 40A via the radio I / F unit 32, and receives the main hook 10 from the extension I / F unit 31 via the extension transmission path 17. A handset off-hook is notified (step 113).
On the other hand, the base unit control unit 39 of the base unit 30B detects that any wireless slave unit 40 has been picked up by the placement detection unit 38 as no placement (step 114), and the extension I / F unit 31 extends the extension. The main device 10 is notified of the absence of the placement through the transmission line 17 (step 115).
[0025]
The control unit 15 of the main apparatus 10 receives a slave unit off-hook notification from the master unit 30A and a no-load detection notification from the master unit 30B via the extension I / F unit 13, and the slave unit off-hook notification is received. An operation determination is made as to whether the operation is a response to an incoming call (step 120).
In this case, the operation determination is performed by combining any one of the notifications and the other notification received within a predetermined time difference from the time when the one notification is received. That is, the slave unit off-hook notification and the no-load detection notification that are continuously received within a predetermined time difference are set as determination targets. Thereby, it can be distinguished from other notification sets. The predetermined time difference may be set for each telephone system as a value that allows the arrival time difference between the two notifications.
[0026]
In this operation determination, first, the notification source of each notification is determined based on the accommodation position in the extension I / F unit 13 of the extension transmission path 17 that has received these notifications. In this case, it is determined that the notification source of the no-load detection notification is the parent device 30B, and the notification source of the child device off-hook notification is determined to be the parent device 30A.
In order to determine the notification source of these notifications, identification information indicating the notification source may be stored in the notification.
[0027]
Then, referring to the management information 16A in the storage unit 16, the incoming call notified in step 102 is an incoming call to the notification origin base unit 30B of the no placement detection notification, and to the notification source base unit 30B of the no placement detection notification. Since the incoming call is being received, it is determined that the slave off-hook notification indicates a response operation in which the wireless slave unit 40A is taken up in a state where the wireless slave unit 40A is erroneously placed on the master unit 30B that is receiving an individual call. Then, the control unit 15 starts a call process for connecting an individual incoming call to the parent device 30B to the wireless child device 40A.
[0028]
First, the control unit 15 notifies the master unit 30B that the incoming call is stopped (step 121), and the master unit control unit 39 of the master unit 30B stops the incoming call display (step 122).
Further, the external line I / F unit 12 is controlled to respond to an individual incoming call from the telephone line 11 to the base unit 30B (step 123), and the switch 14 is controlled to control the call path of the telephone line 11 and the base unit 30A. The call path is connected and the line connection is notified to the parent device 30A paired with the wireless slave device 40A (step 124).
[0029]
In response to this, the base unit control unit 39 of the base unit 30A notifies the wireless slave unit 40A of line connection from the wireless I / F unit 32 (step 125), and communicates with the wireless slave unit 40A via the wireless line. Then, a call path is formed, and the call path is connected to a call path with the main apparatus 10.
As a result, the call path from the telephone line 11 corresponding to the incoming call to the radio telephone 20B to the radio handset 40A is connected, and the call between the individual incoming caller and the radio handset 40A is started (step 126). ).
[0030]
In response to the start of the notification, the control unit 15 of the main apparatus 10 notifies the master unit 30B of a call-in-progress display that displays information such as call partner information, call time, call charge, etc. (step 127). The base unit control unit 39 of the base unit 30B displays these pieces of information on the display unit 34 as a call display (step 128).
[0031]
In this way, the base unit is provided with a mounting detection unit that detects whether or not the wireless slave unit is mounted, and in response to the detection of no mounting by the mounting detection unit, the detection of no mounting is detected from the base unit. The master unit notifies the master unit, and the master unit determines the operation for the slave unit off-hook notification based on the no-set detection notification from the master unit and the slave unit off-hook notification of the wireless slave unit. If the incoming call is received, the handset off-hook notification is determined to indicate a response operation to the incoming call to the notification origin base unit of the no placement detection notification, and the arrival of the no placement detection notification to the notification origin base unit Is connected to a wireless slave device corresponding to the notification source master device of the slave device off-hook notification, so that an incoming call to the master device can be answered by a wireless slave device erroneously mounted on the master device.
[0032]
In addition, since the control unit of the main apparatus is configured to determine the no-loading detection notification and the slave unit off-hook notification received continuously within a predetermined time difference when performing the operation determination, the off-hook of the same wireless slave unit is determined. The no-load detection notification and the handset off-hook notification due to the operation can be easily distinguished from those of other wireless handset operations.
In the above description, the individual incoming call is described as an example of the incoming call to the base unit 30B. However, the present invention is not limited to this, and the normal incoming call and the extension incoming call that do not specify the incoming call destination are the same as described above. Can be applied, and similar effects can be obtained.
[0033]
Further, in the above description, when the operation determination is performed in the control unit 15 of the main apparatus 10, the master unit is used as a notification source of the no-loading detection notification received at almost the same time as the slave unit off-hook notification corresponding to the wireless slave unit 40A. The case where 30A is determined and the incoming call to the parent device 30A is determined as an incoming call to be connected to the wireless slave device 40A has been described as an example, but as an operation determination method for an off-hook operation in the wireless slave device 40A, It is not limited.
For example, in the above description, it is assumed that there are a plurality of telephone lines 11 and a plurality of incoming calls are generated at the same time. However, when there is one telephone line 11, only one incoming call is generated. In such a case, it can be determined that the off-hook operation at the wireless slave device 40A is a response operation to the incoming call. Therefore, in steps 114 and 115 in FIG. 4, the notification of no placement detection from the master unit 30 </ b> B to the main apparatus 10, and the placement detection unit 38 in the master unit 30 can be omitted.
[0034]
Further, the control unit 15 of the main apparatus 10 provides wireless slave device management information 16B as shown in FIG. 5 in the storage unit 16, and manages the parent device 30 on which each wireless slave device 40 is placed. Cases are also conceivable.
In such a case, in step 120, the wireless slave device 40A corresponding to the slave device off-hook notification is placed on the master device 30B by the control unit 15 of the main device 10 based on the wireless slave device management information 16B. I can understand that. Therefore, even in such a case, in steps 114 and 115 in FIG. 4, notification of no-loading detection from the master unit 30 </ b> B to the main apparatus 10, and further the placement detection unit 38 in the master unit 30 may be omitted. it can.
[0035]
FIG. 5 is an explanatory diagram of the wireless slave device management information 16B, FIG. 5 (a) is a configuration example of the wireless slave device management information, and FIG. 5 (b) is an erroneous placement example of the wireless slave device. .
The placement information indicating the placement state detected by the placement detection unit 38 of the base unit 30 is output to the base unit control unit 39 according to the change, and from here to the control unit 15 of the main apparatus 10 by data transmission. Be notified. The placement information indicated by the on-hook / off-hook state detected by the state detection unit 45 of the wireless slave unit 40 is output to the wireless slave unit control unit 49 according to the change, and from here, the base unit 30 is wirelessly communicated. Is notified to the main unit control unit 39 and the control unit 15 of the main apparatus 10 is notified in the same manner as described above.
[0036]
The control unit 15 of the main device 10 compares the placement information notification sources notified from the parent device 30 and the wireless slave device 40. Based on the combination of the parent device 30 and the wireless child device 40 that is the notification source, it is determined which parent device 30 the wireless child device 40 is mounted, and the corresponding relationship is determined by the wireless child device management information 16B. to manage.
At this time, since the placement information notified from the parent device 30 and the wireless slave device 40 is notified to the main device 10 according to the change in the placement state, the wireless slave device 40 is placed on the parent device 30. In this case, the messages arrive at the control unit 15 from the master device 30 and the wireless slave device 40 at substantially equal timing. Therefore, the control unit 15 compares any one piece of placement information with the other placement information that has arrived within a predetermined time difference from the time when the placement information has arrived. Thereby, it can be distinguished from other sets of placement states.
[0037]
Individual identification information is assigned in advance to each parent device 30 and the wireless child device 40. In the example of FIG. 5A, the parent device identification information is managed in association with each wireless child device identification information. ing.
For example, as shown in FIG. 5B, when the wireless slave device 40A is erroneously placed on a different master device 30B from the original master device 30A, the wireless slave device management information 16B in FIG. “30B” is registered as parent device identification information corresponding to the wireless child device 40A. In this example, since the wireless slave device 40B is not placed on any parent device 30, the device is left as registered parent device identification information corresponding to the wireless slave device 40B.
[0038]
Next, with reference to FIG. 6, when the operation of the telephone system according to the present embodiment responds to an incoming call to a different base unit with a wireless handset that has been placed incorrectly, the corresponding wireless handset An example of call processing when there is an individual incoming call to the wireless telephone of the machine will be described. FIG. 6 is a sequence diagram showing another operation of the telephone system according to the present embodiment (busy incoming call processing in an erroneous placement state). In the following, a case where there is one call path between the main apparatus and the radio telephone will be described as an example.
[0039]
First, based on the call processing of FIG. 4 described above, it is assumed that a call is made by responding to an individual incoming call to the radio telephone 20B by the radio slave unit 40A (step 130). In this state, when there is an individual incoming call with the radio telephone 20A as the destination (step 131), the control unit 15 of the main apparatus 10 detects the individual incoming call by a notification from the external line I / F unit 12. .
At this time, since there is only one call path with the radio telephone 20A that is the destination, the radio telephone 20A that is the destination is referred to by referring to the management information 16A stored in the storage unit 16. If the call is in progress, it is determined that the only call path is being used, and the busy incoming call is notified to the master unit 30A (step 132).
[0040]
In response to this, the parent device control unit 39 of the parent device 30A notifies the wireless slave device 40A of the incoming call during a call (step 133).
Thereby, the wireless slave unit control unit 49 of the wireless slave unit 40A controls the voice processing unit 42 to display the busy incoming call by adding the busy ringing tone to the received voice and outputting it (step 134). .
[0041]
Thereafter, when the user who is talking on the wireless slave device 40A notices the busy incoming call and responds to the busy incoming call, when the wireless slave device 40A is placed on the parent device 30B (step 140), the wireless slave device The wireless slave device controller 49 of 40A detects an on-hook according to the output from the state detector 45 (step 141), and notifies the fact to the master device 30A (step 142). In response to this, the parent device control unit 39 of the parent device 30A notifies the main device 10 of the on-hook as a child device on-hook (step 143).
On the other hand, the parent device control unit 39 of the parent device 30B detects the presence of any wireless slave device 40 based on the output from the placement detection unit 38 (step 144), and notifies the main device 10 to that effect (step 144). Step 145).
[0042]
The control unit 15 of the main apparatus 10 receives the slave unit on-hook notification from the master unit 30A and the placement detection notification from the master unit 30B via the extension I / F unit 13, respectively, and responds to the slave unit on-hook notification. Operation determination is performed (step 150).
In this case, the operation determination is performed by combining any one of the notifications and the other notification received within a predetermined time difference from the time when the one notification is received. That is, the slave unit on-hook notification and the placement detection notification received continuously within a predetermined time difference are set as the determination targets. Thereby, it can be distinguished from other notification sets. This predetermined time difference is selected as a value unique to the telephone system from the time difference between both notifications.
[0043]
In this operation determination, first, the notification source of each notification is determined based on the accommodation position in the extension I / F unit 13 of the extension transmission path 17 that has received these notifications. In this case, it is determined that the notification source of the placement presence notification is the parent device 30B, and it is determined that the notification source of the child device on-hook notification is the parent device 30A.
Then, referring to the management information 16A in the storage unit 16, it is determined that the wireless slave unit 40A of the notification source master unit 30A of the slave unit on-hook notification is erroneously placed in a different master unit 30B, and the master unit 30A makes a call Since it is in the state, it is determined that the on-hook operation of the wireless slave device 40A is an end-call operation for a call on the wireless telephone 20A.
[0044]
As a result, the control unit 15 disconnects the telephone line 11 corresponding to the call, and controls the switch 14 to disconnect the call path to the parent device 30A and perform the call termination process (step 151). In addition, the end of the call is notified to the base unit 30A (step 152) and the end of the call is notified to the base unit 30B (step 154).
In response to the end call notification, the base unit control unit 39 of the base unit 30A notifies the wireless slave unit 40A of line release (step 153), disconnects the call path with the wireless slave unit 40A, and Disconnect the call path.
In addition, the base unit control unit 39 of the base unit 30B displays that the call has been terminated in response to the call end notification from the main device 10 (step 155).
[0045]
Then, the control unit 15 notifies the normal incoming call instead of the busy incoming call to the main unit 30A because the call on the radio telephone 20A is terminated in response to the on-hook of the radio slave unit 40A (step 156). As a result, normal incoming call display is performed on base unit 40A (step 157).
[0046]
In this way, when an incoming call to a different base unit is connected to a wireless slave unit placed on the base unit, and there is an incoming call to the wireless handset of the wireless handset, a busy incoming call to that wireless phone Since there is only one call path between the main unit and the radio telephone, the radio handset responds to an incoming call to a different base unit and the only call path is used. Even when there is an incoming call, it is possible to know the incoming call to the original wireless telephone of the wireless handset as a busy incoming call and respond to the incoming call to the original wireless telephone according to the end of the call.
[0047]
The case where there is one call path between the main apparatus 10 and the radio telephone 20A has been described as an example. However, when there are a plurality of call paths and one of the call paths is available, the main apparatus 10 The control unit 15 may notify the base unit 30A, which is the destination, of a normal incoming call instead of the busy incoming call. As a result, it is possible to respond to the incoming call using the speakerphone function of the audio processing unit 33 of the base unit 30A, and even when the wireless handset 40A is responding to the incoming call to the other base unit 30B, A call can be made by responding to the incoming call by the main unit 30A.
[0048]
In the above description, the case where the radio telephones 20A to 20N are connected to the main apparatus 10 as extension telephones has been described as an example. However, in a telephone system in which a general extension telephone is connected in addition to these radio telephones, The present invention can be implemented in the same manner as described above.
Further, the telephone line 11 is not limited to an analog telephone line, and may be a telephone system in which a VoIP line is terminated and connected by an external line I / F unit 12 in addition to an ISDN line.
[0049]
