[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a telephone system, and more particularly to a telephone system having a wireless telephone composed of a parent device and a wireless child device as an extension telephone.
[0002]
[Prior art]
A key telephone device that consists of a main unit connected to a telephone line from the network and a plurality of extension telephones accommodated in the main unit, and that exchanges and connects calls between the telephone line and the extension telephone with the main unit. In such a telephone system, a wireless telephone may be used for some or all of the extension telephones (see, for example, Patent Document 1).
[0003]
This type of wireless telephone is composed of a parent device and a handset-type wireless child device placed on the parent device. In a general extension telephone, the extension telephone and the handset are connected with a cable by a cable, but in this type of wireless telephone, the wireless telephone set in advance is set between the master unit and the wireless slave unit. Are connected by a wireless line using a unique system ID. The master unit is connected to the main unit via a wired extension transmission line, and provides a telephone function similar to that of a general extension telephone by performing data communication with the main unit.
[0004]
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. 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 who is talking on a wireless slave unit moves to another room and the wireless slave unit is not placed in another master unit installed in the destination room, Accordingly, the wireless slave unit may be erroneously placed on the destination master unit.
[0005]
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. 14, 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).
[0006]
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 40A 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.
[0007]
Therefore, while the user tries to respond to the incoming call to the main unit B, the user enters the external line transmission state despite picking up the handset of the main unit B, that is, the wireless sub unit that is erroneously placed on the main unit B. Since the incoming call display on the base unit B is continued, the user cannot understand the situation and is confused.
In order to avoid such a situation, it is necessary to set the base unit and the wireless slave unit that are erroneously set to the same system ID, and to enable wireless communication between them.
[0008]
Conventionally, there has been proposed a method of setting a system ID of a parent device for the wireless slave device according to the placement of the wireless slave device with respect to the parent device (see, for example, Patent Document 2). As shown in FIG. 15, when the wireless slave unit is placed on the master unit and charging is started (step 300), the system ID is transmitted from the master unit to the wireless slave unit by wired communication (step 300). 301) The wireless slave unit compares the system ID from the master unit with the system ID of the wireless slave unit (step 302).
[0009]
If the two system IDs match (step 302: YES), an ID confirmation indicating that the system ID matches can be confirmed by wireless communication from the wireless slave unit to the parent unit (step 303). As a result, the parent device confirms that the system IDs match.
In addition, when the ID of the wireless slave unit is not confirmed (step 302: NO), the wireless slave unit does not notify the ID confirmation. As a result, the master unit is not notified of ID confirmation even after a predetermined time has elapsed since the system ID was sent, so it is determined that the system IDs do not match, and the wireless slave unit is instructed to set a new system ID (step 304). The parent machine also sets a new system ID (step 305). In response to this, the wireless slave unit sets the instructed new system ID (step 306), and both system IDs match to enable wireless communication.
[0010]
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.

[0012]
[Problems to be solved by the invention]
Such a system ID setting method confirms and sets the system ID in response to the start of charging from the parent device to the wireless child device when the wireless child device is placed on the parent device. Therefore, when the base unit is performing wireless communication with the original wireless slave unit using the system ID before the change, the wireless communication is not established according to the change of the system ID, and the original wireless slave unit is used. The wireless line inside is forcibly disconnected.
At this time, if the wireless telephone is installed alone, the user can easily confirm the unused state of the original wireless slave unit. Therefore, by changing the system ID in the unused state, wireless communication can be performed. Cutting should be avoided artificially.
[0013]
However, in a telephone system in which multiple wireless telephones are used as extension telephones and shared by multiple users in a relatively large area, the usage status of the original wireless slave unit cannot be easily confirmed, and wireless communication disconnection occurs. Therefore, there is a problem that the system ID setting method as described above cannot be applied to the telephone system.
The present invention is to solve such problems, and even when a plurality of wireless telephones are shared by a plurality of users as extension telephones, the wireless telephone being used is erroneously deleted without being forcibly disconnected. It is an object of the present invention to provide a telephone system that can change the system IDs of a parent device and a wireless slave device that have been placed so that the wireless slave device can be used as a wireless slave device of the parent device.

[0031]
Next, the operation of the telephone system according to the present embodiment will be described with reference to FIGS. 5 to 7 as an example of call processing to a parent device in an erroneous placement state. FIG. 5 is a sequence diagram showing the operation of the telephone system according to the present embodiment (system ID changing process according to erroneous placement). FIG. 6 shows an erroneous placement example of the wireless slave unit. FIG. 7 is a transition example of each ID management table in FIG.
[0032]
  First, when the user erroneously places the wireless slave device 40A in a 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 slave device 40A has a wireless slave device. The machine control unit 49 receives the output from the state detection unit 45.On hookIs detected (step 101), and notification to that effect is sent from the wireless I / F unit 41 to the base unit 30A via a wireless line (step 102).
  At this time, the wireless slave device control unit 49 notifies the master device 30A of the contents of its own master ID 80 and working ID 82 managed by the ID management table 46A. Here, “a” is notified as the master ID, and “a” is notified as the working ID.
[0033]
  The parent device control unit 39 of the parent device 30A is connected to the wireless child device 40A via the wireless I / F unit 32.On hookA notification of detection is received, and the slave unit is transmitted from the extension I / F unit 31 to the main apparatus 10 via the extension transmission path 17.On hookThe detection is notified (step 103). At this time, the master ID and the working ID from the wireless slave device 40A are also notified to the main apparatus 10.
  On the other hand, the base unit control unit 39 of the base unit 30B detects that an arbitrary wireless slave unit 40 has been placed by the placement detection unit 38 as being placed (step 104), and from the extension I / F unit 31 The main device 10 is notified of the detection of the placement via the extension line 17 (step 105). At this time, the parent device control unit 39 notifies the main device 10 of its own parent device ID 70 managed by the ID management table 36A. Here, “B” is notified as the parent device ID.
[0034]
  In the control unit 15 of the main apparatus 10, the slave unit from the master unit 30 </ b> A is connected via the extension I / F unit 13.On hookThe notification and the presence detection notification from the base unit 30B are received, and the presence / absence of erroneous placement is detected based on the match / mismatch of the notification source radio telephones (step 110: erroneous placement detection means).
  In this case, one of the notifications is compared with the other notification received within a predetermined time difference from the time when the one notification is received. In other words, the slave unit that was received continuously within the predetermined time differenceOn hookNotifications andThere is placementThe detection notification is to be compared. 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.
[0035]
In this example, the working ID included in the handset on-hook detection notification indicates a wireless handset belonging to the radiotelephone 20A, and the base unit ID included in the placement detection notification indicates a baseset belonging to the radiotelephone 20B. Therefore, the notification sources of both are inconsistent and erroneous placement is detected (step 110: YES).
The accommodation position in the extension I / F unit 13 of the extension transmission path 17 between each parent device 30 is individual for each parent device 30. Therefore, you may determine the notification origin of each notification based on the accommodation position which received each notification.
[0036]
Next, the control unit 15 refers to the management information 16B in the storage unit 16 and confirms the operation state of the wireless slave device 40B paired with the notification source master device 30B of the placement detection notification (step 111: state). Confirmation means). The management information 16B is sequentially updated when the control unit 15 controls each parent device 30 and the wireless child device 40 to different operating states.
Here, when it is confirmed that the operation state of the wireless slave device 40B is unused (step 111: YES), the wireless line is not currently used between the master device 30B and the wireless slave device 40B. First, even if the system ID of the base unit 30B is changed, it is determined that the wireless line is not disconnected.
[0037]
Next, the control unit 15 selects a new system ID used between the parent device 30B and the wireless slave device 40A (step 112: ID change instruction means). Here, referring to the ID management table 16A of the storage unit 16, the contents of the working ID 63 and the ID sharing 64 among the wireless handset IDs 62 that can be used by the wireless telephone 20B that is the notification source of the presence detection notification are considered. Then, a sub ID that is not currently used is selected as a new system ID in a predetermined priority order.
In the example of FIG. 4A, since only the master ID “b” is currently used, the younger number sub 1 “b1” of the sub IDs is selected as a new system ID. Note that sub 2 “b2” is selected only when sub 1 is used.
[0038]
Then, the extension I / F unit 13 is instructed through the extension transmission path 17 to the parent machine 30A to change the child machine ID so as to change the system ID of the wireless child machine 40B to the new system ID “b1” (step 113: ID change instruction means).
The base unit control unit 39 of the base unit 30A receives a slave unit ID change instruction from the main unit 10 via the extension I / F unit 31, and sends this instruction from the wireless I / F unit 32 via the radio line. It transmits to the radio | wireless subunit | mobile_unit 40A (step 114). At this time, the parent device control unit 39 does not change its own system ID so that wireless communication with the wireless slave device 40A can be recovered, and remains “a” here.
[0039]
The wireless slave unit control unit 49 of the wireless slave unit 40A receives the slave unit ID change instruction from the master unit 30A via the wireless I / F unit 41, and stores the new system ID included in this instruction in the storage unit 46. Is set to the sub ID 81 of the ID management table 46A, and the working ID 82 is set to “sub” (step 115).
As a result, the system ID of the wireless slave device 40A is changed from the original “a” to “b1” capable of wireless communication with the parent device 30B.
[0040]
Further, in parallel with the slave unit ID change instruction, the control unit 15 changes the system ID from the extension I / F unit 13 to the base unit 30B via the extension transmission path 17 and changes the system ID to the new system ID “b1”. Then, an instruction to change the master unit ID is given (step 116).
The base unit control unit 39 of the base unit 30B receives the base unit ID change instruction from the main apparatus 10 via the extension I / F unit 31, and is indicated by the working ID 73 in the ID management table 36A in the storage unit 36. Set the current system ID, in this case the master ID “b”, to the previous ID 74, then sets the instructed new system ID “b1” to the sub ID 71, and sets the current ID 73 to “sub” (step) 117).
[0041]
Thereby, the system ID of the parent device 30B is changed from the original “b” to the new system ID “b1”, and wireless communication is enabled between the parent device 30B and the wireless slave device 40A.
Thereafter, the control unit 15 of the main device 10 changes the working ID 63 of the base unit 30B of the radio telephone 20B in the ID management table 16A of the storage unit 16 to “sub 1: b1” indicating a new system ID, The system ID used in base unit 30B is updated (step 118).
[0042]
As described above, when an erroneous placement of a wireless slave unit with respect to a different master unit is detected in the main unit, the use state of the wireless slave unit paired with the erroneously placed master unit is confirmed, and Only when it is confirmed that the wireless slave device is not in use, the system ID of the wireless slave device and the master device is changed to a new system ID. Even when shared by users, the system ID of the base unit and the wireless slave unit that has been misplaced is changed without forcibly disconnecting the wireless line in use, and the wireless slave unit becomes the base unit. Can be used as a wireless handset.
[0043]
In addition, the wireless slave unit is provided with a state detection unit that detects the placement of the wireless slave unit on the master unit as an on-hook state, and detects whether the wireless slave unit is mounted on the master unit. A placement detection unit is provided, which notifies the main device of off-hook detection by the state detection unit and detection of placement by the placement detection unit. In response to the discrepancy of the notification source, the wrong placement of the wireless slave unit for different master units was detected. It is possible to easily detect erroneous placement with a relatively simple configuration without performing data communication.
[0044]
In step 111, if the wireless slave device 40A is in a busy state where the wireless line is used, such as during a call, communication, incoming call, or outgoing call (step 111: NO), the change of the system ID is stopped. Alternatively, it is possible to wait until the wireless slave device 40A becomes unused, and change the system ID when the unused state is confirmed.
[0045]
Next, with reference to FIGS. 8 to 10, a description will be given of a processing operation when the wireless slave unit after the change of the system ID is left as an operation of the telephone system according to the second embodiment of the present invention. FIG. 8 is a sequence diagram showing the operation of the telephone system according to the present embodiment (corresponding to leaving the wireless slave unit after changing the system ID). FIG. 9 shows an example of erroneous placement of the wireless slave unit. FIG. 10 is a transition example of each ID management table in FIG.
[0046]
First, as described above, the system IDs of the master unit 30B and the radio slave unit 40A are changed to “b1” in accordance with the erroneous placement of the radio slave unit 40A in the master unit 30B, and wireless communication is possible between them. It is assumed that it is in a state.
In this state, when an incoming call addressed to the radio telephone 20B from the telephone line 11 is detected by the external line I / F unit 12 of the main apparatus 10 (step 120), the extension unit I / F unit 13 and the extension transmission line from the control unit 15 are detected. 17, the incoming call is notified to base unit 30B (step 121). In response to this, the base unit control unit 39 of the base unit 30B controls the voice processing unit 33 to send out a ringtone, and controls the display unit 34 to display the incoming call on the LED or LCD (step 122). .
[0047]
When the user picks up the wireless slave device 40A mounted on the master device 30B in order to respond to an incoming call to the master device 30B, the wireless slave device controller 49 of the wireless slave device 40A has a state detection unit. In response to the output from 45, off-hook is detected (step 123), and off-hook detection is notified from the wireless I / F unit 41 to the base unit 30B via the wireless line (step 124).
The base unit control unit 39 of the base unit 30B receives the off-hook detection 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. Notification of the off-hook detection of the slave unit is sent (step 125).
[0048]
Since the control unit 15 of the main apparatus 10 is receiving an incoming call to the master unit 30B in response to the slave unit off-hook detection notification from the master unit 30B received via the extension I / F unit 13, the control unit 15 detects the slave unit off-hook. It is determined that the notification is a response operation for an incoming call. Then, the external line I / F unit 12 is controlled to respond to the incoming telephone line 11, and the switch 14 is controlled to connect the telephone line 11 and the base 30B. In step 126), the base unit 30B is instructed to connect to the line via the extension I / F unit 13 (step 127).
[0049]
In response to this, the base unit control unit 39 of the base unit 30A stops the incoming call display, notifies the wireless slave unit 40A of the line connection from the wireless I / F unit 32 (step 128), and via the wireless line A call path is formed with the wireless slave device 40 </ b> A, and the call path is connected to a call path with the main apparatus 10.
As a result, a 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 a call between the individual incoming caller and the radio handset 40A is started (step 129). ).
[0050]
Thereafter, when the communication with the other party is terminated and the user does not place the wireless slave device 40A on the master device 30B and performs a call termination operation using the button of the wireless slave device 40A, the wireless slave device 40A The machine control unit 49 detects on-hook based on the output from the key input unit 48 (step 130). Then, on-hook detection is notified from the wireless I / F unit 41 to the base unit 30B via the wireless line (step 131).
At this time, the wireless slave device control unit 49 notifies the master device 30A of its own master ID 80 and working ID 82 managed by the ID management table 46A. Here, “a” is notified as the master ID, and “b1” is notified as the working ID.
[0051]
  The parent device control unit 39 of the parent device 30A is connected to the wireless child device 40A via the wireless I / F unit 32.On hookA notification of detection is received, and the slave unit is transmitted from the extension I / F unit 31 to the main apparatus 10 via the extension transmission path 17.On hookThe detection is notified (step 132). At this time, the master ID and the working ID from the wireless slave device 40A are also notified to the main apparatus 10.
  In addition, in the main | base station 30B, since the radio | wireless subunit | mobile_unit 40A was not mounted, the output of the mounting detection part 38 remains without mounting. For this reason, the main unit control unit 39 does not notify the main device 10 of the detection of placement.
[0052]
The control unit 15 of the main device 10 disconnects the telephone line 11 corresponding to the call by controlling the external line I / F unit 12 in response to the slave unit on-hook detection notification from the master unit 30B, and switches the switch 14 Control is performed to disconnect the call path to the parent device 30A, and the call is terminated (step 133). Also, the line release is notified to the master unit 30A (step 134).
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 135), disconnects the call path with the wireless slave unit 40A, and Disconnect the call path.
[0053]
Further, the control unit 15 of the main apparatus 10 confirms whether or not a placement detection notification from the parent device 30B corresponding to the child device on-hook detection notification is received (step 140). Here, when the detection notification that there is a placement is not received within a predetermined time difference from the slave unit on-hook detection notification (step 140: NO), the radio slave unit 40A that is the slave unit on-hook detection notification source is any master unit. It is determined that it has not been placed on the camera 30 and is left unused (step 141).
In response to this, the control unit 15 refers to the ID management table 16A of the storage unit 16 and uses the master ID of the parent device 30B that has been paired with the wireless child device 40A and the child device on-hook detection notification. The master ID of the notified wireless slave device 40A is compared (step 142).
[0054]
If the master IDs do not match (step 142: NO), the master unit 30B is instructed to share the paired wireless slave unit before the master unit 30B makes a pair with the wireless slave unit 40A. (Step 143).
In response to this, the base unit control unit 39 of the base unit 30B sets the working ID 73 of the ID management table 36A to “shared” and sets the system ID “b1” for the wireless slave unit 40A set to the sub ID 72. The system ID “b” set in the immediately preceding ID 74 is used. Thereby, the main | base station 30B is utilized by both the radio | wireless subunit | mobile_unit 40A and the radio | wireless subunit | mobile_unit 40B.
[0055]
In this way, when a wireless slave is not placed on any parent device and left unused, a pair is formed immediately before the wireless slave device and the parent device paired with the wireless slave device. Since the system ID of the immediately preceding wireless slave device can be used by the master device, it can be avoided that the master device becomes unusable due to the wireless slave device being left unattended.
At this time, the system ID of the immediately preceding wireless slave unit is shared by the master unit together with the system ID of the neglected wireless slave unit, so that the master unit can be used even in the neglected wireless slave unit.
[0056]
Next, with reference to FIG. 11 to FIG. 13, the initialization operation of the changed system ID will be described as the operation of the telephone system according to the third embodiment of the present invention. FIG. 11 is a sequence diagram showing an operation (system ID initialization operation) of the telephone system according to the present embodiment. FIG. 12 shows an erroneous placement example of the wireless slave unit. FIG. 13 is a transition example of each ID management table in FIG.
[0057]
As in the second embodiment described above, when the original wireless slave device 40B is normally placed on the master device 30B in a state where it can be used by the master device 30B (step 150), In the base unit control unit 39, the placement detection unit 38 detects that any wireless slave unit 40 is placed (step 151), and notifies the main apparatus 10 (step 152).
On the other hand, the wireless slave unit control unit 49 of the wireless slave unit 40B detects that the state detection unit 45 is placed on any parent unit 40 and enters the on-hook state (step 153), and detects on-hook to the master unit 30B. (Step 154). At this time, the master ID and the working ID are also notified with reference to the ID management table 46A. Then, the base unit control unit 39 of the base unit 30B notifies the main device 10 of the on-hook detection notification as the slave unit on-hook detection (step 155).
[0058]
The control unit 15 of the main apparatus 10 refers to the ID management table 16A of the storage unit 16 in response to the detection notification of placement and the slave unit on-hook detection notification, and the master unit 30B is in a system ID sharing state. In addition, it is confirmed whether or not the master ID of the parent device 30B matches the master ID of the wireless slave device 40B notified by the notification of detection of the slave device on-hook (step 160).
Here, when the system ID is in a shared state and both master IDs match, it is determined that the regular wireless slave device 40B set as a pair in the system initial state has been returned to the master device 30B, and the control is performed. Unit 15 instructs master device 30B to reset the master ID (step 161: ID change instruction means).
[0059]
In response to this, the base unit control unit 39 of the base unit 30B sets the sub ID 72 and the immediately preceding ID 74 in the ID management table 36A of the storage unit 36 to “empty” and sets the working ID to “master”. Thus, its own system ID is initialized to the master ID (step 162).
Then, the control unit 15 of the main apparatus 10 sets the ID sharing 64 of the parent device 30B to “none” in the ID management table 16A, and sets the working ID 63 to “master” (step 163).
[0060]
As described above, when the master IDs of the master unit and the wireless slave unit match based on the placement detection notification and the slave unit on-hook detection notification according to the placement on the master unit in the shared state of the wireless slave unit Since the master unit is canceled and the system ID is changed to the master ID, the regular wireless slave unit 40B set as a pair in the system initial state returns to the master unit 30B. If it is, the system ID of the parent device can be automatically initialized to the original master ID. Therefore, even if the system ID of the parent device 30 changes, the system ID is initialized at the time when the regular wireless slave device is placed, and the complexity of system ID management can be suppressed.
[0061]
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.
