Description

  The present invention relates to a telephone system, and in particular, includes a main unit connected to a telephone line and a plurality of extension telephones connected to the main unit, and uses a radio telephone composed of a master unit and a wireless slave unit as the extension phone. It relates to the telephone system.

In a telephone system composed of a main unit connected to a telephone line and a plurality of extension telephones connected to the main unit, a radio telephone may be used as the extension telephone.
This wireless telephone is composed of a parent device and a wireless child device that make a pair, of which the parent device is connected to the main unit, and the wireless child device is connected to the parent device via a wireless line. This type of wireless telephone is called a curled cordless type cordless telephone because there is no curled cord for connecting the handset to the telephone body as compared with a general extension telephone. Usually, a master unit and a wireless slave unit that are paired as the same wireless telephone perform wireless communication using the same preset identification information, that is, a system ID, so that the master unit and the wireless slave unit of other wireless telephones can communicate with each other. It is the structure which avoids the interference of.

In a telephone system that connects such wireless telephones as extension telephones, a function that controls the operating state triggered by picking up a handset, that is, a wireless handset from the master unit, is proposed, similar to general extension telephones. Has been.
For example, if a wireless handset is picked up after entering the other party's dial number from the base while the wireless handset is placed, the outside line is captured using the pick-up as a trigger, and the partner input in advance at the base There is a function of making an outside line transmission using a dialed number, that is, a preset dial function (see, for example, Patent Document 1).

  In addition, as a general function, when the line is captured by using the on-hook call function such as the hands-free function of the master unit or the speaker receiving function, these functions are canceled when the wireless slave unit is picked up. Automatic call switching function for switching to a call on a wireless slave unit. When an incoming call is received while the wireless slave unit is mounted, a call is made on the wireless slave unit in response to the incoming call when the wireless slave unit is picked up. There is an incoming call automatic answering function to start, and a line automatic catching function for catching a line when the wireless slave is picked up from the master.

In such a conventional telephone system, since the wireless handset of each wireless telephone can be freely carried, it may be erroneously placed on the base of other wireless telephones. And the wireless slave device belong to different wireless telephones, the control of the master device and the wireless slave device by the main device is not linked, and the user may be confused.
For example, with the preset dial function, if a wrongly placed wireless slave unit is picked up after entering the other party's dial number on the master unit, the wireless unit is paired with the wireless slave unit as described above and the wireless The outside line is captured when the slave is picked up.

At this time, as in the case of normal placement, the dial is not transmitted even though the external line is captured according to the picking up of the wireless slave by the automatic line capturing function, and the user is confused.
In order to avoid such confusion, the operation state of the parent device paired with the picked-up wireless slave device is shifted to the operation state of the parent device that has been misplaced, and the parent state of the wireless child device that has taken up the operation state is changed. A method to continue by switching to a machine is conceivable. As a result, the operation is continued in the picked-up wireless slave device, and user confusion can be avoided.

The applicant has not yet found prior art documents related to the present invention by the time of filing other than the prior art documents specified by the prior art document information described in this specification.
JP-A-6-315045

However, when the operation switching control as described above is performed in the conventional telephone system, there is a problem that it can be abused to escape the application of the setting contents such as the outside line transmission restriction set for each base phone or radio telephone. is there.
For example, when an external line is transmitted from a master unit that is permitted to make outgoing calls using the preset dial function, and a wireless slave unit of another wireless telephone that is erroneously placed on the base unit is picked up, the operation transition function is simply used. When it is used, regardless of whether or not there is a restriction on outgoing line transmission to the parent unit of the picked-up wireless slave unit, the operation state is continued at the parent unit of the wireless slave unit, and an external call with the wireless slave unit becomes possible .

  The present invention is intended to solve such a problem, and provides a telephone system that can prevent abuse of operation switching control for continuing the operation of a parent device in which a wireless slave device is erroneously placed by the wireless slave device. The purpose is to do.

In order to achieve such an object, a telephone system according to the present invention includes a main device connected to a telephone line and a plurality of extension telephones connected to the main device, and a parent device connected to the main device. In a telephone system that uses a wireless telephone set as an extension telephone that is composed of a pair of wireless slave units connected to the master unit via a wireless line and in which the location of the wireless slave unit is provided in the master unit, Transition management means for determining whether or not to shift to a desired operation state for the parent device based on setting information set in advance corresponding to the parent device, and at least a transmission operation state, an incoming operation state, or a line of the parent device When a wireless slave device of a second master device different from the first master device is picked up from the first master device in one of the capturing states, the second master device is the first master device. Transition to the same operating status as the operating status of the base unit To determine ability or not the migration management unit, if it is determined that the change is possible, along with shifting the second master unit to the first in the same operating state and the operating state of the master unit, the first base unit And a call control means for canceling the operation state .

At this time, if it is determined by the transition management means that the transition is not possible, the call control means continues the operation state in the first master unit and shifts to the operation state for the first master unit or the wireless slave unit. It may be instructed to notify that it is impossible.
In addition, regarding the call origination operation, any of the operations performed from dial input or destination selection performed before line supplementation to calling of the destination may be used.

The present invention is provided with a transition management means for determining whether or not the master device can be shifted to a predetermined operation state based on setting information preset for the master device. When a wireless slave device of a second master device different from the first master device is picked up from the first master device in one of the operation states of the transmission operation state, the reception operation state, or the line capture state, The transition management means determines whether or not the second master unit can be shifted to the same operating state as the first master unit, and if it is determined that the transition is possible, the second master unit is changed to the second master unit. Since the operation state of the first parent device is shifted to the same operation state as that of the first parent device and the operation state of the first parent device is canceled, the wireless child device is erroneously placed on the parent device of a different wireless telephone. Even in this case, avoid user confusion caused by picking up the wireless slave unit With wear, it can prevent abuse of such operation switch control.

The key input unit 48 is a circuit unit that detects a key operation by a user.
The wireless slave unit control unit 49 has a microprocessor such as a CPU and its peripheral circuits, and reads and executes the program in the storage unit 46, whereby the hardware and the program cooperate with each other in the wireless slave unit 40. It is a functional part that controls each part.

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.

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. The presence / absence of the child device 40 may be detected.
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, when a current of a predetermined value or more is always passed between the charging terminal 37A and the charging terminal 44A, or a predetermined potential is applied, the charging terminal 37A and the charging terminal 44A are in a fully charged state. The presence / absence of electrical connection to may be detected.

FIG. 4 is an explanatory diagram of the placement management information 16B, FIG. 4 (a) is a configuration example of the placement management information, and FIG. 4 (b) is an erroneous placement example of the wireless slave unit.
Detection information indicating a change in the placement state detected by the placement detection unit 38 of the parent device 30 is notified to the control unit 15 of the main apparatus 10 by data transmission. Also, the detection information indicating the change in the mounting state detected by the state detection unit 45 of the wireless slave device 40 is notified to the parent device control unit 39 of the parent device 30 by wireless communication, and the main device 10 in the same manner as described above. The control unit 15 is notified.

In the control unit 15 of the main apparatus 10, the erroneous placement determination means 15B determines whether or not the time difference between the reception timings of the detection information notified from the parent device 30 and the wireless slave device 40 is within a predetermined allowable time difference, and these detections. Based on the combination of the parent device 30 and the wireless slave device 40 that is the information notification source, it is determined on which parent device 30 the wireless slave device 40 is placed, and the corresponding relationship is managed by the placement management information 16B. .
At this time, even if the master unit 30 and the radio slave unit 40 constitute different radio telephones 20, the same operation and control operations are common to the master unit 30 and the radio slave unit 40. Are received almost simultaneously. Therefore, the placement relationship between the parent device 30 and the wireless slave device 40 can be determined by comparing the reception timings of these detection information.

In the master unit 30 and the wireless slave unit 40, even if a common operation or control operation is detected, a processing delay occurs to some extent until the detection information is confirmed by the main device 10. For example, when the wired extension transmission path 17 is used for data transmission from the master unit 30 to the main apparatus 10, there is almost no processing delay required for the data transmission.
On the other hand, the data transmission from the wireless slave unit 40 to the main device 10 via the master unit 30 is caused by the wireless protocol because a radio line is interposed between the wireless slave unit 40 and the master unit 30. To some extent, and there is also some processing delay in the detection information transfer processing in the master unit 30. Therefore, a predetermined allowable time difference may be provided for the determination of the reception timing. The allowable time difference may be set for each telephone system as the sensitivity of determination.

  Further, in order to determine the notification source of the detection information, identification information indicating the notification source may be stored in the information. Further, each wireless telephone 20 is connected to the extension I / F unit 13 of the main apparatus 10 via the extension transmission path 17 in a one-to-one relationship, and the extension I / F unit that has received the detection information. Based on the 13 port positions, it may be determined from which radiotelephone 20 the detection information is from.

Individual identification information is assigned in advance to each parent device 30 and the wireless child device 40. In the example of FIG. 4A, the parent device identification information is managed in association with each wireless child device identification information. ing.
For example, as shown in FIG. 4B, when the wireless slave device 40A is erroneously placed on the master device 30B different from the original master device 30A, the placement management information 16B in FIG. “30B” is registered as parent device identification information corresponding to the wireless slave 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.

FIG. 5 is a configuration example of the setting information 16C. In this example, the setting information used for the determination process of the migration management means 15C includes the presence / absence of external line accommodation for each parent device, the tenant identification to which each parent device belongs, the type of external line assigned to each parent device, and each parent device Settings such as the presence / absence of outgoing call restrictions on are managed. These settings may be managed for each wireless telephone instead of the base unit.
In the transition management means 15C, when a certain parent device is shifted from the current operation state to another operation state, the setting information related to the parent device is checked in the setting information 16C to determine whether or not the operation state can be shifted.

  For example, when the external line transmission operation state of the first base unit is shifted to the second base unit during a preset dial operation or the like, the external line is accommodated in the second base unit as the transfer destination, and the tenant Same as the first master unit that is the migration source, the outside line assigned to the second master unit that is the migration destination is not dedicated to incoming calls, and the outgoing call restriction is set for the second master unit that is the migration destination Only when it is confirmed that it has not been made, it is determined that the transition to the outside line transmission operation state is possible, and if any one of these setting contents is not satisfied, the transition to the outside line transmission operation state is impossible. Judge.

Next, the operation of the telephone system according to the first embodiment of the present invention will be described with reference to FIG. FIG. 6 is a sequence diagram showing the operation of the telephone system according to the first embodiment of the present invention.
In the present embodiment, a preset dial function for transmitting to a destination selected by a preset operation on a base unit in which the wireless handset is erroneously placed in response to picking up the wireless handset will be described. In the following, it is assumed that the wireless slave device 40A constituting the wireless telephone 20A in a pair with the parent device 30A is erroneously placed on the parent device 30B of another wireless telephone 20B.

When a preset operation such as input of a destination dial number, redial selection, or destination selection in the phone book is performed on the base unit 30B while the wireless handset 40A is erroneously placed on the base unit 30B, The base unit control unit 39 of the base unit 30B detects this preset operation via the key input unit 35, and transmits it from the extension I / F unit 31 to the main apparatus 10 via the extension transmission path 17 (step 100). In response to this, the call control means 15A of the main apparatus 10 receives the preset operation via the extension I / F unit 13, and stores the fact that the master unit 30B is in the preset transmission operation state and its counterpart dial number. It is managed by 16 call control information 16A.
Thereafter, when the wireless slave device 40A is picked up from the master device 30B, the electrical connection between the charging terminal 37A of the master device 30B and the charging terminal 44A of the wireless slave device 40A is disconnected, and the charging operation is stopped (step 101). .

The base unit control unit 39 of the base unit 30B detects the picking up of the wireless slave unit 40 by the placement detection unit 38 based on the stop of the charging operation for the arbitrary radio slave unit 40 (40A) that has been placed (step S40). 102).
Then, the base unit control unit 39 transmits the pick-up of the wireless slave unit 40 detected by the placement detection unit 38, that is, the slave unit off-hook, from the extension I / F unit 31 to the main apparatus 10 via the extension transmission path 17 ( Step 103).

On the other hand, the wireless slave device control unit 49 of the wireless slave device 40A detects the pick-up from the arbitrary parent device 30 by the state detection unit 45 based on the stop of the charging operation of the arbitrary parent device 30 (30B) (step 104). .
Then, the wireless slave device control unit 49 transmits the pick-up from any parent device 30 detected by the state detection unit 45, that is, the slave device off-hook, from the wireless I / F unit 41 to the parent device 30A via the wireless line (step). 105).
The base unit control unit 39 of the base unit 30A receives the slave unit off-hook via the wireless I / F unit 32 and transmits it from the extension I / F unit 31 to the main apparatus 10 via the extension transmission path 17 (step 106). ).

  The call control means 15A of the main apparatus 10 receives these slave unit off-hooks via the extension I / F unit 13, refers to the placement management information 16B of the storage unit 16, and sets the master unit 30B and the radio slave unit 40A. The placement relationship is confirmed (step 110). Here, when it is confirmed that these are in an incorrect placement relationship (step 110: YES), the operation state of the parent device 30B is confirmed with reference to the call control information 16A in the storage unit 16, and the parent device 30B. In step 111, it is determined that it is necessary to switch the call control related to the preset dial operation at the base station 30A, and the base unit 30A paired with the picked-up wireless handset 40A is the switching destination of the call control.

Then, the transition management means 15C confirms the setting information 16C in the storage unit 16 (step 112), and whether or not the radio telephone 20A of the parent device 30A can be shifted to the operation state of the parent device 30B (here, the preset dial operation state). Is determined (step 113).
In this case, since it is determined whether or not the outside line transmission operation state can be changed during the preset dial operation, for example, the outside line is accommodated in the base unit 30A, and the tenant to which the base unit 30A belongs is the same as the base unit 30B. Only when it is confirmed that the external line assigned to the main unit 30A is not dedicated to incoming calls and no outgoing call restriction is set for the main unit 30A, it is determined that the transition to the external line outgoing operation state is possible. If any one of these setting contents is not satisfied, it is determined that the transition to the outside line transmission operation state is impossible.

  In this way, when it is determined that the migration management unit 15C can migrate (step 113: YES), the call control unit 15A controls the outside line I / F unit 12 to capture a free outside line from the telephone line 11, Call processing is performed to the destination specified by the preset operation from the master unit 30B (step 114), and the master unit 30B is instructed to cancel the preset dial operation state via the extension I / F unit 13 (step 115). .

Next, the call control means 15A controls the switch 14 to connect the outside line used for the preset dial operation and the call path of the master unit 30A, and to the master unit 30A via the extension I / F unit 13. An instruction to shift to a call state using the machine 40A is given (step 116).
As a result, the master unit 30A shifts to the operation state of the master unit 30B, and the external line used for transmitting the preset dial operation in the master unit 30B is switched and connected to the wireless slave unit 40A via the master unit 30A. Then, the call to the other party selected by the preset operation and the call are started by the wireless slave unit 40A (step 117).

On the other hand, when it is determined in step 113 that the transition is impossible (step 113: NO), the call control means 15A does not instruct the master unit 30A to shift to the operating state of the master unit 30B, and the master unit 30A, While maintaining the operating state of 30B, the master unit 30A is instructed to display busy in the slave unit via the extension I / F unit 13 (step 120).
Further, the call control unit 15A invalidates the off-hook of the wireless slave unit 40A for the base unit 30B and continues the preset dial operation in the on-hook state.

The base unit control unit 39 of the base unit 30A receives the slave unit busy display at the extension I / F unit 31 via the extension transmission path 17, and displays the slave unit busy display via the wireless I / F unit 32. It transmits to 40A (step 121).
The wireless slave device control unit 49 of the wireless slave device 40A receives the slave device G display by the wireless I / F unit 41 via the wireless line, controls the voice processing unit 42 and the display unit 47, and is in a busy state (call By displaying the audible / visible state in an inaudible state, the user is informed that the operation cannot be continued (step 122).

  As described above, when the wireless slave device 40A of the wireless telephone 20A different from the parent device 30B is picked up from the parent device 30B that is performing the outgoing operation, the incoming operation, or the line acquisition, the transition management unit 15C of the main device 10 Whether or not the base unit 30A of the wireless slave unit 40A can be shifted to the operation state of the base unit 30B is determined based on the setting information 16C. Only when it is determined that the transition is possible, the call control unit 15A and the base unit 30B And the operation is continued in the master unit 30A, so that the same operation as the case where the regular radio slave unit 40B is taken up from the master unit 30B can be realized in the radio slave unit 40A. Even if the device is misplaced on the base unit of a different wireless telephone, it is possible to avoid user confusion caused by picking up the wireless handset and to prevent such an operation switching control. It can be prevented.

Therefore, for example, since the call operation following the preset dial operation of the master unit 30B is continued in the master unit 30A of the radio slave unit 40A erroneously placed in the master unit 30B, the regular radio slave unit 40B is used in the preset dial operation. In the same manner as when picking up from the parent device 30B, the wireless slave device 40A can make a call with the other party that made a call by the preset dial operation of the parent device 30B, thereby avoiding confusion for the user.
In addition, when the outgoing information restriction is set in advance in the base unit 30A in the setting information 16C, for example, the transition management unit 15C determines that the transition to the preset dial operation state in the base unit 30A is impossible. The operation is not switched to the machine 30A, and appropriate call control based on the original setting information 16C is performed.

In the present embodiment, the case where the telephone line 11 accommodated in the main apparatus 10 is used to make a call to the network side has been described as an example. However, the present invention is not limited to this and the extension I of the main apparatus 10 is not limited thereto. The present invention can also be applied to a case where an extension is transmitted to another radio telephone 20 connected to the / F unit 13.
In addition, when a call is in progress, it means any state in the series of operations from when a call preparation operation such as line capture or partner selection operation is started until the other party answers after the actual dial transmission. Incoming call operation means that any state in the series of operations from the detection of an incoming call to the start of a call in response to the incoming call until the start of a call in response to the call. It points to being in. In addition, the term “line capturing” includes not only a call but also all states where an external line or an internal line is captured.

Next, the operation of the telephone system according to the second embodiment of the present invention will be described with reference to FIG. FIG. 7 is a sequence diagram showing the operation of the telephone system according to the second embodiment of the present invention.
In the first embodiment described above, the case where the preset dial function is used in the parent device in which the wireless slave device is erroneously mounted has been described as an example. However, in the present embodiment, the wireless slave device is erroneously mounted. The automatic call switching function for canceling the on-hook call state in the master unit and switching to the call in the wireless slave unit when the wireless slave unit is picked up will be described. In the following, it is assumed that the wireless slave device 40A constituting the wireless telephone 20A in a pair with the parent device 30A is erroneously placed on the parent device 30B of another wireless telephone 20B.

First, it is assumed that an external line on-hook call without using the wireless slave device 40A is performed on the master device 30B in which the wireless slave device 40A is erroneously mounted using a hands-free function, a speaker reception function, or the like (step 130). At this time, the main apparatus 10 manages that the base unit 30B is in an on-hook call state by using the call control information 16A in the storage unit 16.
In this operation state, when the wireless slave device 40A is picked up from the master device 30B (step 131), the master device control unit 39 of the master device 30B charges the arbitrary wireless slave device 40 (40A) that has been placed. Based on the stop of the operation, the placement detector 38 detects picking up of the wireless slave device 40 (step 132). Then, the base unit control unit 39 transmits the pick-up of the wireless slave unit 40 detected by the placement detection unit 38, that is, the slave unit off-hook, from the extension I / F unit 31 to the main apparatus 10 via the extension transmission path 17 ( Step 133).

On the other hand, the wireless slave device controller 49 of the wireless slave device 40A detects the stop of the charging operation of the arbitrary parent device 30 (30B) as an off-hook by the state detector 45 (step 134).
Then, the wireless slave device control unit 49 transmits the pick-up from any parent device 30 detected by the state detection unit 45, that is, the child device off-hook, from the wireless I / F unit 41 to the parent device 30A via the wireless line ( Step 135).
The base unit control unit 39 of the base unit 30A receives the slave unit off-hook via the wireless I / F unit 32 and transmits it from the extension I / F unit 31 to the main apparatus 10 via the extension transmission path 17 (step 136). ).

  The call control means 15A of the main apparatus 10 receives these slave unit off-hooks via the extension I / F unit 13, refers to the placement management information 16B of the storage unit 16, and sets the master unit 30B and the radio slave unit 40A. The placement relationship is confirmed (step 140). Here, when it is confirmed that these are in an incorrect placement relationship (step 140: YES), the operation state of the parent device 30B is confirmed with reference to the call control information 16A in the storage unit 16, and the parent device 30B. When it is determined that switching of the call control related to the external line call operation is necessary, the parent device 30A paired with the picked-up wireless slave device 40A is determined as the switching destination of the call control (step 141).

Then, the transition management means 15C confirms the setting information 16C in the storage unit 16 (step 142), and determines whether or not the parent device 30A can be shifted to the operation state of the parent device 30B, here the outside line call operation state (step 143). ).
In this case, since it is determined whether or not the outside line call operation state can be shifted, for example, it is confirmed that the main line 30A contains an external line and the tenant to which the main unit 30A belongs is the same as the main unit 30B. Only when it is determined that the transition to the outside line call operation state is possible, and when any one of these setting contents is not satisfied, it is determined that the transition to the outside line call operation state is impossible.

In this way, when it is determined that the transition management unit 15C can transition (step 143: YES), the call control unit 15A instructs the master unit 30B to cancel the on-hook call via the extension I / F unit 13. (Step 144).
Then, the master unit 30B is instructed to release the call path via the extension I / F unit 13 (step 145), and the master unit 30A is instructed to shift to the call state via the extension I / F unit 13 ( In step 146), the switch 14 is controlled to switch the external line used for the on-hook call by the base unit 30B from the call path of the base unit 30B to the call path of the base unit 30A (step 147).

  As a result, the outside line that has been on-hook on the base unit 30B is connected to the wireless slave unit 40A via the master unit 30A, and the telephone conversation with the partner is resumed on the wireless slave unit 40A. (Step 148).

On the other hand, if it is determined in step 142 that the transition is not possible (step 143: NO), the call control means 15A instructs the master unit 30A to display busy in the slave unit via the extension I / F unit 13 (step 143). 150).
Further, the call control unit 15A invalidates the off-hook of the wireless slave unit 40A for the base unit 30B and continues the call operation in the on-hook state.

The base unit control unit 39 of the base unit 30A receives the slave unit busy display at the extension I / F unit 31 via the extension transmission path 17, and displays the slave unit busy display via the wireless I / F unit 32. Transmit to 40A (step 151).
The wireless slave device control unit 49 of the wireless slave device 40A receives the slave device G display by the wireless I / F unit 41 via the wireless line, controls the voice processing unit 42 and the display unit 47, and is in a busy state (call By displaying the audible / visible display of the disabled state, the user is notified that the operation cannot be continued (step 152).

As described above, the automatic call switching operation in the parent device 30B is also continued in the parent device 30A of the wireless child device 40A erroneously placed in the parent device 30B. Similarly to the case where 40B is picked up from the parent device 30B, the wireless slave device 40A can make a call with the other party of the on-hook call of the parent device 30B.
Further, in the setting information 16C, for example, when the master unit 30A is previously set to not accommodate an outside line, the transition management unit 15C determines that the transition to the outside line call operation state in the master unit 30A is impossible. The operation is not switched to the machine 30A, and appropriate call control based on the original setting information 16C is performed.

Further, in the present embodiment, the case where an outside line call is made using the telephone line 11 accommodated in the main apparatus 10 has been described as an example, but the present invention is not limited to this, and the extension I of the main apparatus 10 The present invention can also be applied to a case where an extension call is made with another wireless telephone 20 connected to the / F unit 13.
In the present embodiment, the case where an on-hook call is being performed in base unit 30B has been described as an example. However, a state in which an external line that is not connected to the other party is captured, for example, a state in which an external line is only captured. Even in a state in which a dial signal is being sent to the captured outside line, a state in which the other party is being called, etc., the call can be switched in the same manner as described above. Therefore, the present embodiment can be applied in any state as long as it is in an on-hook line capture state, that is, in a state where an outside line or an extension line is captured in the on-hook state.

Next, the operation of the telephone system according to the third embodiment of the present invention will be described with reference to FIG. FIG. 8 is a sequence diagram showing the operation of the telephone system according to the third embodiment of the present invention.
In the first embodiment described above, the case where the preset dial function is used in the master unit in which the wireless slave device is erroneously mounted will be described as an example. In the second embodiment, the wireless slave device is erroneously described. The case where the automatic call switching function is used in the base unit installed has been described. In the present embodiment, an automatic incoming call response function for responding to an incoming call to the parent device by the wireless child device triggered by picking up the erroneously placed wireless child device will be described. In the following, it is assumed that the wireless slave device 40A constituting the wireless telephone 20A in a pair with the parent device 30A is erroneously placed on the parent device 30B of another wireless telephone 20B.

When an incoming call arrives from the telephone line 11 to the parent device 30B (wireless telephone 20B) while the wireless slave device 40A is erroneously placed on the parent device 30B, the call control means 15A of the main unit 10 Incoming call is notified to base unit 30B via F unit 13 (step 160). At this time, the main apparatus 10 manages that the base unit 30B is in an incoming state by the call control information 16A in the storage unit 16.
Base unit control unit 39 of base unit 30B receives the incoming call notification from main apparatus 10 via extension I / F unit 31 and controls voice processing unit 33 and display unit 34 to display the incoming call (step 161). ).

  In response to this incoming call display, when the wireless slave device 40A erroneously placed is picked up from the master device 30B (step 162), the master device control unit 39 of the master device 30B causes any wireless device that has been placed. Based on the suspension of the charging operation for the child device 40 (40A), the placement detector 38 detects the picking up of the wireless child device 40 (step 163). Then, the base unit control unit 39 transmits the pick-up of the wireless slave unit 40 detected by the placement detection unit 38, that is, the slave unit off-hook, from the extension I / F unit 31 to the main apparatus 10 via the extension transmission path 17 ( Step 164).

On the other hand, the wireless slave device control unit 49 of the wireless slave device 40A detects the stop of the charging operation of any parent device 30 (30B) as an off-hook by the state detection unit 45 (step 165).
Then, the wireless slave device control unit 49 transmits the pick-up from any parent device 30 detected by the state detection unit 45, that is, the child device off-hook, from the wireless I / F unit 41 to the parent device 30A via the wireless line ( Step 166).
The base unit control unit 39 of the base unit 30A receives the slave unit off-hook via the wireless I / F unit 32 and transmits it from the extension I / F unit 31 to the main device 10 via the extension transmission path 17 (step 167). ).

  The call control means 15A of the main apparatus 10 receives these slave unit off-hooks via the extension I / F unit 13, refers to the placement management information 16B of the storage unit 16, and sets the master unit 30B and the radio slave unit 40A. The placement relationship is confirmed (step 170). Here, when it is confirmed that these are in an incorrect placement relationship (step 170: YES), the operation state of the parent device 30B is confirmed with reference to the call control information 16A in the storage unit 16, and the parent device 30B. In step 171, it is determined that switching of call control related to the incoming call response operation is necessary, and the base unit 30 </ b> A paired with the picked-up wireless handset 40 </ b> A is determined as the switching destination of the call control.

Then, the transition management means 15C confirms the setting information 16C in the storage unit 16 (step 172), and determines whether or not the radio telephone 20A of the base unit 30A can shift to the operating state of the base unit 30B, here the incoming call operating state. (Step 173).
In this case, since it is determined whether or not the incoming call operation state can be changed, for example, when it is confirmed that an external line is accommodated in the parent device 30A and the tenant to which the parent device 30A belongs is the same as the parent device 30B. Only when it is determined that the transition to the incoming operation state is possible, and any one of these setting contents is not satisfied, it is determined that the transition to the incoming operation state is impossible.

In this way, when it is determined that the migration management unit 15C can migrate (step 173: YES), the call control unit 15A instructs the master unit 30B to stop displaying the incoming call via the extension I / F unit 13. (Step 174).
Then, the base station 30A is instructed to shift to the call state via the extension I / F unit 13 (step 175), and the outside line I / F unit 12 is controlled to respond to the telephone line 11 where the incoming call is detected. Then, the switch 14 is controlled to connect the telephone line 11 to the call path of the base unit 30A (step 176).

  As a result, call control for incoming calls to the parent device 30B (wireless telephone 20B) is switched to the wireless child device 40A via the parent device 30A, and a call with that partner is performed by the wireless child device 40A. (Step 177).

On the other hand, if it is determined in step 173 that the transition is not possible (step 173: NO), the call control means 15A instructs the master unit 30A to display busy on the slave unit via the extension I / F unit 13 (step 173). 180).
Further, the call control unit 15A invalidates the off-hook of the wireless slave unit 40A for the base unit 30B and continues the incoming operation in the on-hook state.

The base unit control unit 39 of the base unit 30A receives the slave unit busy display at the extension I / F unit 31 via the extension transmission path 17, and displays the slave unit busy display via the wireless I / F unit 32. Transmit to 40A (step 181).
The wireless slave device control unit 49 of the wireless slave device 40A receives the slave device G display by the wireless I / F unit 41 via the wireless line, controls the voice processing unit 42 and the display unit 47, and is in a busy state (call The user is informed that the operation cannot be continued by audibly / visiblely displaying (impossible state) (step 182).

As described above, since the incoming call automatic response operation in the parent device 30B is also continued in the parent device 30A of the wireless slave device 40A erroneously placed in the parent device 30B, the regular wireless slave device is used in the incoming call automatic response operation. Similarly to the case where 40B is picked up from the parent device 30B, the wireless slave device 40A can make a call with the destination of the incoming call to the parent device 30B, and the user's confusion can be avoided.
Further, in the setting information 16C, for example, when the master unit 30A is previously set to not accommodate an outside line, the transition management unit 15C determines that the transition to the outside line incoming operation state in the master unit 30A is impossible. The operation is not switched to the machine 30A, and appropriate call control based on the original setting information 16C is performed.

  In the present embodiment, an incoming call from the telephone line 11 accommodated in the main apparatus 10 has been described as an example. However, the present invention is not limited to this, and the extension I / F unit 13 of the main apparatus 10 is not limited to this. The present invention can also be applied to extension incoming calls from other connected wireless telephones 20.

Next, a specific example of erroneous placement determination will be described with reference to FIG. FIG. 9 is an explanatory diagram showing a specific example of erroneous placement determination. Here, a case where the wireless slave device 40A is erroneously placed on the master device 30B will be described as an example.
When the wireless slave device 40A is picked up from the master device 30B, as described above, the placement detection unit 38 of the master device 30B detects picking up of the wireless slave device 40 (40A), and the master device control unit 39 detects the main device. 10 is notified of the handset off-hook.
The control unit 15 of the main device 10 receives the off-hook notification at time T1, starts a monitoring timer that measures a predetermined allowable time difference tm at the reception timing (confirmation timing), and sets the wireless device corresponding to the off-hook notification. The time difference until the reception timing of the off-hook notification from the machine is determined.

On the other hand, the state detection unit 45 of the wireless slave device 40A also detects picking up from the master device 30 (30B), and the slave device control unit 49 of the wireless slave device 40A transmits the slave device to the main device 10 via the master device 30A. Off-hook is notified.
The control unit 15 of the main apparatus 10 receives the on-hook notification from the wireless slave device 40A at time T2. At this time, if the monitoring timer started in response to the off-hook notification from the master unit 30B is operating, and then the monitoring timer ends its operation at time T3, the erroneous placement determination unit 15B The placement relationship is determined based on the off-hook notification from any wireless slave unit received during the operation of the monitoring timer started in response to the off-hook notification from.

In the case of FIG. 9, since the off-hook notification is received from the wireless slave device 40A during the operation of the monitoring timer, the time difference between the reception timings of the off-hook notifications received from the master device 30B and the wireless slave device 40A is within the allowable time difference. It is determined that the detected information indicates an (identical) operation or control operation, and it is determined that the wireless slave device 40A is placed on the transmission source of these off-hook notifications, that is, the master device 30B. Then, this placement relationship is stored in the placement management information 16 </ b> B of the storage unit 16.
If an off-hook notification is received from the wireless slave device 40A after the monitoring timer has expired, the time difference between the reception timings of the off-hook notifications received from the master device 30B and the wireless slave device 40A is outside the allowable time difference, and the same operation is performed. Alternatively, it is determined that the notification is not an off-hook notification indicating a control operation, and it is determined that the transmission source of these off-hook notifications, that is, the parent device 30B and the wireless slave device 40A are not in a mounting relationship.

  In FIG. 9, the case where erroneous placement is determined based on the reception timing of the off-hook notification has been described as an example, but on-hook notification that is notified when the wireless slave device is placed on the parent device instead of the off-hook notification The erroneous placement may be determined based on the reception timing, and any other placement may be determined in the same manner as long as the notification indicates a common (same) operation or control operation for the master unit and the wireless slave unit.

  In addition, the erroneous placement determination by the erroneous placement determination means 15B is not limited to the method of determining based on the reception timing of these notifications. For example, a common (same) operation or The time information indicating the timing at which the control operation was performed is detected by the master unit and the wireless slave unit, respectively, and notified to the main unit, and the time difference of the timing indicated by these time information is compared with the allowable time difference, etc. Other determination methods may be applied.
