Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone set used in offices and the like, and more particularly to a telephone transfer apparatus for transferring an incoming call to an appropriate place when a calling party is absent.

[0002]

2. Description of the Related Art A telephone used in an office or the like is provided with a function for transferring a call received when the user is absent or for notifying that the user is absent. However, when using these functions, it is necessary for the user to explicitly set the transfer or to set the absence, and in practice, these functions are often not used effectively.

Conventionally, in order to solve such a problem, various techniques for automating telephone transfer have been proposed. For example, in Japanese Patent Application Laid-Open No. 1-246946, "Guest Location System", a user stores his / her own location in a switchboard by a special dial operation, and then transfers the telephone call to the registered telephone. A method is described. Japanese Unexamined Patent Publication No. 4-180495 “Private telephone system” includes an ID that an individual has for setting a transfer.
A method is described in which a card is used and an incoming call is transferred to the nearest telephone while the ID card is inserted in the nearest telephone.

[0004] Further, Japanese Patent Application Laid-Open No. Sho 6 (1994) discloses a method for realizing automatic telephone transfer without requiring a user to perform an explicit operation.
JP-A-3-87830, "Extension calling system",
02151, "Answering machine", JP-A-8-107
No. 453, “Telephone device”, Japanese Patent Application Laid-Open No. 8-26523O, “Absent call system” or 1996,
Those described in IEICE Spring Institute, D-186, "Study of a simple personal terminal environment using a wireless card" and the like are known.

The methods disclosed in these patent publications or references carry an apparatus for generating an identification signal of an individual by means such as a weak radio wave to each individual, and are incorporated in a telephone at a desk or in an office. Receivers located at various locations within the office detect whether the called party is near the telephone at their desk, and if not, detect where the called party is without the user's explicit setting operation. Diverts the telephone call to a telephone near where the caller is now,
Make sure the phone is connected to the other party.

[0006]

However, in the above-described automated telephone transfer system, for example, when the called party is moving, an inappropriate telephone transfer destination may be selected. That is, even if the called party is on the move,
A receiver near the travel route responds and the transfer setting to the telephone is set.In this case, even if the call arrives at the telephone, the called party has already passed the location and received the call. The disadvantage is that the caller cannot pick up the telephone.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is possible to select an appropriate transfer destination telephone and transfer a call even when the called party is moving. It is an object of the present invention to provide a telephone transfer device capable of performing the above.

By referring to the history information, the staying state determining means determines whether each individual has passed or stayed at the place, and sets an appropriate telephone number as a transfer destination.

[0013]

FIG. 1 is a block diagram showing a first embodiment of the present invention, in which a telephone network 10 and a telephone 11 connected thereto, and a signal carried by an individual and identifying the individual are shown. ID transmitting means 1 for transmitting the ID, ID transmitting means 1
The ID receiving and collating means 5 which receives the signal from the ID and performs collation with the ID registered in advance to determine whether or not the ID should be notified to another telephone transfer device, and is registered in the ID receiving and collating means 5. A registration ID table 6 for holding IDs, a data communication unit 7 for transmitting and receiving detected ID data, and an address of a transfer device of a transmission destination of the ID data detected by the data communication unit 7 by the ID reception matching unit 5 From the ID device address correspondence table 8 used to obtain the ID, the other telephone transfer device 9 with which the data communication unit 7 communicates, and the ID data information from the ID reception collation unit 5 and the data communication unit 7. A staying state history 4 that records the staying state of an individual at each location as a history, and a staying state determination unit 3 that uses this information to determine an appropriate transfer destination It is constituted by the transfer absence control unit 2 that performs control to return that is absent or transfer an incoming call to the phone in the other by the information from the staying state determining means 3.

Next, the operation of the first embodiment of the present invention will be described. Each individual always carries the ID transmitting means 1, and ID information for identifying each individual is transmitted from the ID transmitting means 1 using, for example, weak radio waves in a coded form. On the other hand, the ID receiving and collating means 5 is installed near a telephone used by each individual, and detects ID data from the ID transmitting means 1 within a radius of several meters.

The ID of the individual who normally uses the telephone 11 is registered in the ID reception collation means 5 in advance. The number of IDs to be registered may be plural. For example, if the telephone 10 is placed on a personal desk and is not normally used by another person, only one ID is registered. If the telephone 10 is shared, all the IDs of the individuals using the telephone are registered. Register. When receiving the signal from the ID transmitting means 1, the ID receiving / collating means 5 collates whether or not the ID belongs to an individual registered in advance by using the data of the registered ID table 6.

As a result of the collation, if the ID is a registered individual ID, the received time information, the ID, and the address information of the own telephone transfer apparatus are notified to the staying state judging means 3. If it is not a registered individual ID,
The data communication means 7 is notified of the ID information and the time information. The address information is used to identify each telephone transfer device, and is used to identify a place where the personal ID is detected at the time of data communication between the telephone transfer devices by the data communication means 7 and the stay state determination means 3. Used for

The above-mentioned information notification to the stay state determination means 3 and the ID communication means 7 of the ID reception collation means 5 is performed at a sampling interval of one second to several seconds, and is detected between the previous notification and the present notification. The information of the ID is notified at the same time. If no ID is detected, no notification is made. For example, ID1 and ID2 are registered ID table 6
It is assumed that a plurality of ID transmitting means 1 are approaching the ID receiving and collating means 5. At this time, if ID2 and ID3 are detected simultaneously during one sampling time,
The ID reception matching means 5 notifies the ID information ID2 and the time information to the staying state determination means 3, and notifies the data communication means 7 of the ID information ID3.

The data communication means 7 uses the ID device address correspondence table 8 to obtain the address information of the telephone transfer device in which the ID notified from the ID reception collation means 5 is registered, The ID information, the time information, and the own device address are transmitted to another expressed telephone transfer device 9. The means for data communication is not particularly limited, and data may be exchanged via a LAN in an office or via an exchange using a telephone network.
When using the telephone network, the telephone number of the telephone to which the telephone transfer device is connected is used as a means for expressing the device address. The data transmitted from the data communication means 7 to the other telephone transfer device 9 represented by the address is received by the data communication means in another telephone transfer device having the corresponding address, and the received data corresponds to the data. It is notified to the staying state determination means in the other telephone transfer device having the address.

In the above process, the staying state judging means 3 sends the data detected by the own telephone transfer device from the ID reception collating means 5 with respect to the ID registered in advance in its own telephone transfer device. From the data communication means 7, the data detected by the other telephone transfer devices is received as three sets of ID information, time information, and address information of the detected telephone transfer device, respectively.

The staying state judging means 3 classifies the received information for each ID registered in the registration ID table 6 and registers it in the staying state history 4. In the staying state history 4, the detected device address, detection start time, and number of detections are recorded for each registration ID. When registering in the history, if the ID information is detected continuously for a predetermined number of times, the device address and the detection start time are recorded in the history, and thereafter the number of times of detection is increased each time there is detection. . In addition, information of a device address for which detection information is not obtained for a certain period is deleted from the history. The reason for providing a delay from detection to registration and deletion is to deal with detection errors such as noise.

For example, suppose that the staying state judging means 3 receives data related to ID2 as shown in FIG. 2 from time t1 to present (t0). This data indicates that the person indicated by ID2 is 30
This indicates that the user has moved to a location near 96. If the data relating to ID2 recorded in the staying state history 4 at this time is shown as the state of the staying state history 4 at times t2, t5, and t0, they are as shown in FIGS. 3 to 5, respectively. Here, the number of detections before registration or deletion in the history is set to two each. Therefore, as shown in FIG.
At the stage, the history data registered at t3 is deleted, and no data is registered.

FIG. 6 shows a case where the same ID is detected by a plurality of telephone transfer devices at the same time.
This indicates that the person indicated by ID2 has moved from the vicinity of the telephone having the telephone number 3215 to a place near 3096. However, since the installation locations of both devices are close to each other, at time t5 and at time t6, both persons are located. The data shows how the ID is detected by the telephone transfer device. in this case,
The data on ID2 recorded in the staying state history 4 is
The states of the staying state history 4 at times t2, t6, and t0 are as shown in FIGS. 7 to 9, respectively. t
In FIG. 8 showing stage 6, data indicating detection from two telephone transfer devices is registered. In FIG. 9 showing the stage of t0, the data relating to the device address 3215 registered earlier has been deleted.

The staying state judging means 3 registers the history in the staying state history 4 as described above, and uses this data to determine the optimum place for the user to receive a call in FIG.
And the transfer / absence setting is notified to the transfer / absence control means 2. Hereinafter, the operation of the staying state determination means will be described with reference to the flowchart of FIG.

First, when there is no data registered in the staying state history 4, it is not possible to determine an appropriate transfer destination of the telephone call.
(Steps A1 and A9). Next, when the number of registered data is one, the data is set as target processing data (steps A2 and A3). When there are a plurality of registered data, the data most recently registered in the history is set as the target processing data (steps A2 and A2).
4).

Next, it is checked whether or not the count number of the target data exceeds a predetermined value (step A5). Based on this value, it is determined whether the user is staying at the place or passing through. This value is determined based on the sampling period of the ID receiving / collating means 5 and the range in which the signal of the ID transmitting means is detected.
For example, when the sampling period is 1 second and the detection range is 3 m, the counter passes the number of times equal to or less than 2 times, and more than 2 times is regarded as staying. This means that the average human walking speed is about 1.5 m / s
Is a value that can be determined from

When the count value is equal to or less than the predetermined value, it is determined that the called person is moving, and since there is no appropriate transfer destination of the call, the absence setting is notified to the transfer absence control means 2. (Steps A5 and A9). On the other hand, if the count value is larger than the predetermined value, it is determined whether the registered data is its own device address (step A6), and if it is detected by a telephone transfer device at another location, the corresponding device address (telephone address) No.) is notified to the transfer absence control means 2 (step A7). If it is the address of the own device, it is determined that the user is at his / her own seat, and the transfer and absence setting cancellation is notified to the transfer / absence control means 2 (step A8).

In the above, the I for one person is registered in the registration ID table 6.
In the case where only D is registered, if one user is sharing one phone and a plurality of IDs are registered in the registration ID table 6, even one person is detected in his or her seat. If you do not set the absence and forwarding, and only when no one is detected in your seat, you can set forwarding or absence, or determine the priority between each ID,
When a plurality of registration IDs are detected, a method of setting transfer according to the order can be adopted.

The transfer absence control means 2 sets the absence and transfer of the telephone set 11 based on the notification from the stay state determination means 3 described above. With the above-described configuration, even when the called user is moving, the call is not transferred to the telephone on the moving route, but is transferred to the telephone at the place where the user stays for a certain period of time. In this case, an appropriate telephone transfer destination is selected.

As a modification of the first embodiment, the ID transmitting means 1 does not always transmit a weak radio wave,
A format that receives a pilot signal from the reception collation unit 5 and returns a response to the pilot signal as ID information may be used. Thereby, the power consumption of the ID transmitting means 1 can be suppressed.

FIG. 11 is a block diagram showing a second embodiment of the present invention. In this embodiment, information from the telephone device 17 and a plurality of telephone devices 17 for detecting ID data attached to each telephone from the ID transmitting means and notifying the ID data to the telephone exchange device 16 are collected. It comprises a telephone exchange-side device 16 which manages and manages call forwarding, and the ID transmitting means 1.

The telephone device 17 further stores the ID
It comprises an ID receiving means 14 for detecting ID information from the transmitting means and the data communication means 7. Further, the telephone exchange device 16 stores the ID from the data communication means 7.
The information is received, and by referring to the ID telephone number correspondence table 13 which describes the correspondence between the telephone number of the telephone attached to each telephone side device 17 and the personal ID registered in the telephone side device, History registration means 12 for adding and outputting information of telephones with registered IDs, and a staying state history for retaining received ID information with registered telephone numbers for each telephone number and for each personal ID 4
And a stagnant state judging means 3 for deciding an appropriate transfer destination by using the information of the stagnating state history 4, and transferring an incoming call to the telephone to another or absent by the information from the stagnating state determining means 3. Transfer absence control means 2 for performing control for replying to the presence, and telephone exchange means 15 for controlling connection between telephones.
It is composed of

Next, the operation of the second embodiment will be described with reference to FIG. When detecting the ID data from the ID transmitting means 1, the ID receiving means 14 detects the detected ID data.
The data communication means 7 is notified of the data and time information and the telephone number registered in the telephone device. Here, the telephone number registered in the telephone device corresponds to the address of the telephone transfer device in the first embodiment, and uses the telephone number of the telephone attached to the telephone device. This notification is performed at a sampling period of one second to several seconds as in the first embodiment. The data communication unit 7 that has received the notification sends the data to the history registration unit 12.

The history registration unit 12 adds the information of the telephone number in which the ID included in the received data is registered, and notifies the stay state determination unit 3 of the information. At this time, the telephone to which the detected ID is registered is obtained by searching the ID telephone number correspondence table 13. The staying state judging means 3 classifies the received data for each telephone number and for each ID and registers it as the staying state history 4.

The contents of this data are the same as those described in the first embodiment. That is, it is registered in the same form as that shown in FIGS. 3 to 5 and FIGS. 7 to 9. Further, the subsequent processes in the staying state determination unit 3 and the transfer absence control unit 2 using the staying state history 4 are performed in the same manner as in the first embodiment. Finally, the telephone exchange means 15 receiving the instruction from the transfer absence control means 2 sets or cancels the actual transfer and absence.

In the second embodiment, similarly to the first embodiment, as a modified example, the ID transmitting means 1 does not always transmit a weak radio wave, and the ID transmitting means 1 Upon receiving the pilot signal, the response to the
A format returned as D information can be adopted.

According to the second embodiment of the present invention, the first
In addition to the effects of this embodiment, the registered ID table 6 and the ID device address correspondence table 8 managed by each telephone transfer device are collectively managed as the ID telephone number correspondence table 13 by the telephone exchange side device. Therefore, it is possible to easily maintain the consistency of data, and to simplify the configuration of a plurality of telephone-side devices, thereby reducing the realization cost.

And the process up to the notification to the destination estimating means 18 is as follows:
This is the same as the first embodiment of the present invention.

Upon receiving the three-piece ID information notified from the ID reception collating means 5 and the data communication means 7, the destination estimating means 18 classifies the information for each ID, and detects the ID. The time and the detected device address are registered in the movement history 19 in order of time.

For example, when the destination estimating means 18 receives information as shown in FIG. 13 from time t1 to the present time (t0), the moving history 19 includes ID2 as shown in FIG.
Is recorded. At the same time, this information is also notified to the staying state determination means 3, but no data is registered in the staying state history 4 because the staying time at each detection location is short. In this case, the stagnation state determining means 3 uses the state in FIG.
0, the process proceeds to step A9 of the flowchart shown in FIG. 0. In the case of the present embodiment, the destination estimating means is not requested to the transfer absence control means 2 as in the first embodiment. The processing is shifted to 18.

The destination estimating means 18 refers to the movement history 19 and the detection device layout information 20 to predict a place where the called person who will be traveling will pass after a few seconds, and sets the transfer to the telephone at that place. do. Detector layout information 2
In 0, the location of the device is described in two-dimensional coordinates, and information on the path between the locations is also described as adjacent information.

FIG. 15 shows an example of the detection device layout information 20. For predicting the transfer destination, the walking speed and the moving direction of the user are calculated from the device address information observed in the past from the movement history 19. For this, the coordinates of the arrangement location of each device described in the detection device layout information 20 are used. By calculating the walking speed and the moving direction, candidates for devices that will pass through in the future are obtained.

In the case of the history shown in FIG. 14, in the past, the direction from the device address 3214 to the direction of the device address 3213 is reached, and from the coordinate values shown in FIG.
Is expected to reach. At this time, when a plurality of candidates are obtained, the most appropriate device address candidate is obtained from the adjacent information from the last detected location and the elapsed time by using the adjacent information in FIG. Then, the obtained device address is notified to the transfer absence control means 2 as a transfer destination. When a suitable candidate cannot be obtained, for example, when a considerable time has passed since the last detection, the absence setting is notified to the transfer absence control means 2.

The above-described processing is repeatedly executed each time there is an information notification from the ID reception collation means 5 and the data communication means 7. In addition to the effect of the first embodiment, the absence of transfer Since the probability of setting is reduced, the chance that the caller of the telephone can talk to the other party can be increased.
