2. Description of the Related Art Conventionally, a device having a configuration shown in FIG. 18 is known as a device having this type of call transfer function. The system shown in FIG. 18 is called a business line business telephone system, and in FIG.
, and a general public network interface section 104.

[0004] Wired business telephone interface section 1
01 is connected to wired business telephones 105-111.

The control unit 102 includes a connection control unit 102A that connects the wired business telephone to the general public network 112 and between the wired business telephones, and a memory control unit 102B that controls the memory unit 103.

[0006] The memory unit 103 has a first area 103 that stores correspondence between wired business telephones and dial-in numbers.
A. A second area 103 that stores the correspondence between a wired business telephone and a forwarding destination wired business telephone set by the telephone.
B is provided.

[0007] The general public network interface section 104 is
It is connected to the general public network 112.

[0008] Now, the first area 103A of the memory section 103
Assume that the stored contents of are as shown in FIG.

[0009] Here, at point A, the wired business telephone 10
Let us assume that a person using 5 goes to point B for a meeting or the like. Generally, this type of wired business telephone (hereinafter referred to as "EKT") 105 is not portable, so the user of this EKT 105 sets call forwarding from the EKT 105 before moving. At this time, two cases are possible. In other words, case 1 where you set up call forwarding to the assistant's EKT106 and the EK closest to destination B.
This is case 2 in which incoming call transfer is set to T111. In this case, the stored contents of the second area 103B of the memory section 103 are as shown in FIGS. 20 and 21. Here, FIG. 20 shows the case 1, and FIG. 21 shows the case 2.

By the way, in case 1, all incoming calls are transferred to the assistant's EKT 106, and the assistant responds to the incoming calls. Also, when you are on the move, call the nearest E.
From KT, and after moving from EKT111.

[0011] In case 2, all incoming calls are EKT1.
11, and the user of EKT111 will contact you. At this point, you may not be able to receive calls while you are on the move, so you may not be able to receive calls. Also, calls can be made from the nearest EKT while moving, or from EKT1 after moving.
Start from 11.

[0012] In a device with such a configuration, in Case 1, there is no major problem since all incoming calls are answered by the assistant, but the person in question cannot directly answer incoming calls during free time, such as during breaks in a meeting. There is a problem. Furthermore, in Case 2, there is a problem in that the caller cannot keep up with incoming calls while the caller is on the move.

[0013] Also, a device having the configuration shown in FIG. 22 is conventionally known. This device is called a business cordless telephone system, and a wireless connection control device 200 (hereinafter referred to as "LCU") is a BS interface unit 201.
, a control section 202, a memory section 203, and a PBX interface section 204.

[0014] The BS interface unit 201
It is connected by wire to S205 to S207. Control unit 202
is a connection control unit 202A that connects the slave PS and the PBX 100 via the base BS, and connects the slave PS in zones of different base BSs via the respective base BS;
It is configured to include a memory control section 202B that controls the memory section 203.

[0015] The memory unit 203 includes a first area 203A that stores the correspondence between the handset PS and dial number,
It has a second area 203B that stores the zone of which base unit BS is located.

[0016] The PBX interface unit 204
PBX100 is connected to the general public network 112.
connected to. Furthermore, zone Z1 of the base unit BS205 includes slave units PS208-210, zone Z2 of the base unit BS206 includes slave units PS211-212, and the base unit BS20
Zone Z3 of No. 7 includes PS213 to PS214.

Assume now that the contents of the first area 203A of the storage section 203 are as shown in FIG.

[0018] The LCU 200 determines which base unit B each slave unit PS is connected to.
I am constantly checking to see if it is in the S zone. There are two types of methods. To briefly explain, in the first method, base units BS 205 to 207 send broadcast signals using a control channel (control CH) at different timings and at predetermined intervals according to instructions from LCU 200. is transmitted wirelessly, and each slave station PS sequentially receives the broadcast signals from base stations BS 205 to 207, compares the received electric field strengths, and stores the base station BS number corresponding to the maximum received electric field strength. Since each child device PS was able to recognize the parent device BS of the zone in which it exists, the memory unit 20 of the LCU 200
In this method, a registration request signal is wirelessly transmitted to the base unit BS at random intervals using a control CH until the base unit BS is registered in the second area 203B of No. 3.

[0019] In the second method, the user of each handset PS operates the location registration key to control the control C from the handset PS.
H is used to wirelessly transmit the notification signal and the base unit BS205~
207 receives the notification signal, measures the received electric field strength, and transmits the data to LCU 200. L
The CU 200 compares the data from the base units BS 205 to 207, and stores the base unit BS that transmitted the largest amount of data in the memory unit 20.
3 in the second area 203B as the base unit BS of the slave unit PS, and the master unit B to the slave unit PS via the base unit BS.
This is a method of wirelessly transmitting the S number.

By the above method, the second area 203 is now
It is assumed that the storage contents of B are as shown in FIG.

[0021] Here, a case will be explained assuming that a person using the slave PS 208 at point A goes to point B for a meeting or the like. In this configuration, the user of the handset PS208 can carry the handset PS208, so while the user is within the zone Z1 of the base unit BS205, the handset PS208 is connected to the base unit BS205.
You can make and receive calls via 5. While the slave unit PS208 is moving, it leaves the zone Z1 of the base unit BS205 and returns to the base unit BS20.
When entering zone Z2 of No. 6, the storage unit 203 of the LCU 200
The memory contents of the second area 203B of the base unit BS206 are as shown in FIG.
It is possible to make and receive calls via S206. When leaving zone Z2 of the base unit BS206 and entering zone Z3 of the base unit BS207 where point B is located, the second area 203B of the storage unit 203 of the LCU 200 becomes as shown in FIG.
You can make and receive calls via .

As described above, it is convenient to be able to make calls from anywhere, but on the other hand, there is a problem in that calls can be received no matter where you are. For example, when a call arrives during a meeting, the ring tone sounds, or the call must be answered.

[0023] Therefore, a configuration in which a so-called don't disturb function is added may be considered, but in the case of this configuration,
There is a problem in that incoming calls are canceled while the don't disturb mode is set.

[0024]Also, a configuration may be considered in which an answering function is added, but in this configuration, the OGM (Outgoing Message), ICM (Incoming Call Message) recording section, and playback section for the hardware are also considered. It is necessary to have these components in the slave PS, and such a configuration goes against the trend of making the slave PS smaller and lighter.In addition, if these configurations are included in the base unit BS or LCU, system control becomes complicated. become. Additionally, adding an answering function increases costs, and there is also the problem of not being able to respond to incoming calls in real time.

[0025] Therefore, it is necessary to consider a system in which calls are received on the person's PS during free time such as a break in a meeting at the destination, and when the person is unable to answer during a meeting, the calls can be transferred to the assistant's PS.

[0026]

[Problems to be Solved by the Invention] As mentioned above, in the conventional company-owned line business telephone system, when moving within the office for meetings etc., it is not possible to carry a wired business telephone with you, so it is difficult to receive calls before moving. Transfer settings will be made. In this case, if you set the forwarding destination to the assistant's wired business phone, there will be no major problem since all incoming calls will be answered by the assistant, but there is a problem that the person in question will not be able to answer incoming calls during free time, such as during a break in a meeting. be. Furthermore, if the forwarding destination is set to the wired business phone closest to the new location, there is the problem that incoming calls will not be picked up while the person in question is on the move.

[0027] In addition, with conventional office cordless telephone systems, you can carry a handset and make and receive calls no matter where you are in the zone of the base unit. When you have to answer an incoming call, the problem is that you can receive the call from anywhere.

[0028]The present invention eliminates these problems and enables the person carrying the handset (the person in question) to do so at the destination.
During free time, such as during a break in a meeting, the caller receives a call on his/her handset and is able to answer the call.Also, if there is an incoming call during a meeting and the call cannot be answered, the call will not be received on the person's handset and the assistant will be able to answer the call. To provide a mobile radio device equipped with a call transfer function capable of transferring an incoming call to a handset and having an assistant respond in real time.

[Configuration of the invention]

[0030]

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a plurality of base units that individually configure zones and establish wireless connections with a plurality of slave units within the zones;
a wireless connection control device that is connected by wire to the plurality of base units, and when the slave unit moves from the current zone to another zone, it is possible to make and receive calls in the zone after the movement; In a mobile radio device equipped with a call transfer function that transfers an incoming call to a handset to a preset forwarding destination handset, a call forwarding function setting means for setting the call forwarding function; between a first call reception control mode in which incoming calls to the handset are received by the transfer destination handset, and a second call reception control mode in which calls to the handset are directly received by the handset. The present invention is characterized by comprising a mode switching means for selectively switching the mode, and a call transfer function canceling means for canceling the call transfer function.

[0031]

[Function] When the call forwarding function is set by the call forwarding function setting means, the first incoming call control mode allows incoming calls to the handset to be transferred to the forwarding destination handset, and the incoming calls to the handset to be transferred to the handset. A second call reception control mode in which calls are directly received can be selectively switched by the switching means.

[0032] In other words, the person carrying the handset sets the forwarding destination handset (destination handset) to which incoming calls are to be forwarded from the handset he is carrying (main handset) before or while moving, and transfers the incoming calls to the handset. When the call forwarding function is set, this information is transmitted to the wireless connection control unit (LCU) via the base unit in the zone where the handset is located.
The person carrying this handset can selectively switch between a first call control mode in which the handset transfers incoming calls to the forwarding handset in the destination zone, and a second call control mode in which the handset directly receives and answers incoming calls. Even if the call forwarding function is set, the person carrying the handset can switch to the second incoming call control mode to receive incoming calls during free time, such as during breaks in a meeting. You can respond accordingly. Furthermore, when the person carrying the handset cannot respond to an incoming call due to a meeting or the like, the user switches to the first call control mode in which the incoming call to the handset is transferred to a preset forwarding destination handset. At this time, when there is an incoming call connection request to the main handset, the LCU does not send an incoming call signal to the main handset, but sends an incoming call signal to the transfer destination handset via the base device in the zone where the transfer destination handset is located. In this case, information indicating that the call is a forwarded call can also be sent at the same time, and this information causes the forwarding destination handset to sound a different ring tone than when the call is directly addressed to the caller's own machine. The assistant using the transfer destination handset receives this incoming call and responds.

[0071] At this time, from PBX100 to LCU200
When there is an incoming connection request to the dial-in number 1001, the connection control unit 202A of the control unit 202 of the LCU 200 refers to the first area 203A of the memory unit 203 and determines that the incoming call is an incoming call to the slave PS 208. identify with. Then, referring to the third area 203C of the memory unit 203, in this case, the handset PS208 is currently in the process of setting incoming call forwarding and is in the mode of forwarding incoming calls, so the forwarding destination handset PS209
Controls transfer of incoming calls to.

Here, the second area 20 of the memory section 203
3B, since the slave PS209 is within the zone Z1 of the base BS205, it transmits an incoming signal and information indicating that the incoming call is a forwarded call to the slave PS209 via the base BS205.

When the control unit 1 of the handset PS 209 identifies the data with the data reception identification unit 1E, the display control unit 1B controls the call LED 18 so that the call LED 18 blinks at a different cycle from when a call is directly addressed to the unit itself. At the same time, the notification sound control unit 1C controls the notification sound generation unit 21 to generate the notification sound generator 2 at a frequency different from that when the call is directly addressed to the device itself.
2. The ringtone sounds.

[0074] Thereby, the assistant using the handset PS209 operates the call key 14 to respond to the incoming call.

The control unit 202 of the LCU 200 adds one to the cumulative count value in the fourth area of the memory unit 203 each time the memory control unit 202B transfers this incoming call to the slave PS 209, and the connection control unit 202A adds the cumulative count value of the fourth area of the memory unit 203 by one. ,
Referring to the second area 203B of the memory unit 203, in this case, since the slave PS208 is in zone Z3 of the base BS207, the accumulated count value is transmitted to the slave PS208 via the base BS207.

[0076] When the control unit 1 of the slave unit PS 208 identifies the data by the data reception identification unit 1E, the control unit 1 of the slave unit PS 208
B holds the data and controls the LCD display 20 to update the display of the cumulative number of call transfers.

This operation will be explained with reference to the flowchart in FIG.

That is, the standby mode "0" shown in FIG.
Or in the state of standby mode "1" (step 34
1) When the LCU 200 transmits the cumulative number of transfers via the base unit BS 207 (step 342), this LCU
Every time the cumulative number of transfers is transmitted from BS 200 to base unit BS 207, the current display on LCD display 20 is updated (step 344), and the current display is set to standby mode "0" or standby mode "1".
become.

However, in step 342, the LCU 200
If it is determined that the cumulative number of transfers is not transmitted via the base unit BS 207, the standby mode "0" or the standby mode "1" continues (step 343).

Next, regarding the transfer mode switching operation when the user of the handset PS208 has free time such as a meeting break at a destination and switches from the mode of transferring incoming calls to the mode of receiving and answering incoming calls. , will be explained with reference to the flowchart of FIG.

In this case, first, the user of the slave PS 208 operates the transfer key 15 to set the switching. That is, the handset PS 208 checks the input of the transfer key 15 in the incoming call transfer mode "1" (step 351) (
Step 352), if the transfer key 15 is not input, the incoming call transfer mode "1" continues as it is, but the transfer key 15 is not input.
When there is an input, the transfer flag is set to "0" (step 354). In this case, the contents of the third area 13C of the memory unit 13 of the slave PS 208 are as shown in FIG.

Next, the controller 1 of the slave PS 208 controls the data generator 2 by the data controller 1H to generate information consisting of the slave PS number 208, the transfer destination PS number 209, and the transfer flag "0". Then, the frequency synthesizer section 12 is controlled by the transmission/reception control section 1G to set the frequencies of the wireless transmitting section 4 and the wireless receiving section 8 to the control CH, and the data of information B is processed in the same procedure as for information A. So, base unit B
Transmitted to LCU 200 via S207 (Step 3
55).

The control unit 202 of the LCU 200 uses the memory control unit 202B to control the third area 203 of the memory unit 203.
The contents of C are rewritten from information A to information B as shown in FIG.
A reception completion signal of information B is sent to 08.

When the slave PS 208 identifies the reception completion signal using the data reception identification section 1E of the control section 1 (step 356). The control unit 1 turns off the green lighting of the transfer mode display two-color LED 19 by the display control unit 1B and sends a PS to the user.
208 notifies that it is in the mode of receiving and responding to an incoming call (step 357), and becomes the incoming call transfer mode "0" (step 357).
step 358).

In this state, from the PBX100 to the LC
When there is an incoming connection request to dial-in number 1001 to U200, connection control unit 2 of control unit 202 of LCU 200
02A refers to the first area 203A of the memory unit 203 and identifies that the incoming call is an incoming call to the slave PS208. Then, with reference to the third area 203C of the memory unit 203, the slave PS208 is currently in the process of setting incoming call forwarding, but since it is in the mode of receiving and responding to incoming calls, the slave PS208 is controlled to receive calls. Here, referring to the second area 203B of the memory unit 203, the slave PS208 is connected to the base unit BS20.
Since the terminal is in zone Z3 of No. 7, it transmits an incoming signal to the slave PS208 via the base station BS207. Handset PS208
When the control unit 1 identifies the data by the data reception identification unit 1E, the display control unit 1B controls the call LED 18 to display an incoming call by blinking it at the cycle of incoming calls directly addressed to the device itself, and also outputs a notification sound. The control unit 1C controls the notification sound generation unit 2.
1, and the notification tone generator 22 sounds a ringtone at the frequency when a call is received directly to the own device. As a result, the handset PS20
The user 8 operates the call key 14 to respond to this incoming call. Here, since the memory control unit 202B of the control unit 202 of the LCU 200 does not change the cumulative count value in the fourth area of the memory unit 203, the LC of the slave PS 208
The display of the cumulative number of transferred calls on the D display 20 does not change.

[0086] When the conference starts again, the user of the handset PS 208 operates the transfer key 15 to change the incoming call from the mode for receiving and responding to incoming calls, that is, incoming call transfer mode "0", before starting the conference. Settings are made to switch to the transfer mode, that is, the incoming call transfer mode "1". That is,
In the state of call transfer mode "0" (step 358), the input of the transfer key 15 is checked (step 359). Here, if the transfer key 15 is not input, the incoming call transfer mode continues as "0", but if the transfer key 15 is input, the transfer flag is set to "1" (step 354). In this case, the contents of the third area 13C of the memory unit 13 of the slave PS 208 are as shown in FIG. 6 above.

Next, the control unit 1 of the slave PS 208 controls the data generation unit 2 by the data control unit 1H, and from this slave PS number 208, the transfer destination slave PS number 209, and the transfer flag "1". information A is generated, and the data of this information A is sent to L via the base unit BS 207 using the same procedure as for information B.
The information is transmitted to the CU 200 (step 362).

[0088] As a result, the control section 202 of the LCU 200
The memory control unit 202B converts the contents of the third area 203C of the memory unit 203 into information B as shown in FIG.
is rewritten to information A, and a reception completion signal of information A is transmitted to the slave PS 208 via the base BS 207.

When the slave PS 208 identifies this reception completion signal by the data reception identification unit 1E of the control unit 1 (step 363), the display control unit 1B lights up the transfer mode display two-color LED 19 in green, and the user Handset PS20
8 notifies that the mode is to transfer incoming calls, and the incoming call transfer mode becomes "1" (step 356).

In this state, from the PBX100 to the LC
When the U200 receives an incoming connection request to the dial-in number 1001, it transfers the incoming call to the slave unit PS209 as described above, and adds 1 to the cumulative count value in the fourth area of the memory unit 203 of the LCU 200. , and transmits the data to the slave PS 208 via the base BS 207. When the control unit 1 of the slave PS 208 identifies the data using the data reception identification unit 1E, the display control unit 1B holds the data and causes the LCD display 20 to display the cumulative number of incoming calls added by 1.

Next, the operation of canceling the call transfer mode when the user of the handset PS 208 finishes the conference at the destination and cancels the call transfer mode will be described with reference to the flowchart shown in FIG. This operation to cancel the call transfer mode can be performed in any zone, but here the handset 208 is the base unit BS.
Suppose that you return to zone Z1 of No. 205 and perform the operation at point A.

In the state of standby mode "0" or standby mode "1" shown in FIG. 15 (step 371), it is checked whether there is an input on the setting key 16 (step 372). If not, continue in standby mode “0” or standby mode “1” (step 3).
73).

[0093] In step 322, when it is determined that the setting key 16 has been input by the user of the PS 208, the slave PS 208 uses the control CH to transmit the call transfer mode cancellation signal generated by the data generation unit 2. is transmitted to the LCU 200 via the base unit BS 205 (step 374).

The control unit 202 of the LCU 200 uses the memory control unit 202B to control the third area 203 of the memory unit 203.
The contents regarding the slave PS208 of C are erased, and a reception completion signal of the cancellation signal is transmitted to the slave PS208 via the base unit BS205.

When the control unit 1 of the slave unit PS 208 identifies the reception completion signal by the data reception identification unit 1E (step 375), the memory control unit 1D causes the memory unit 1D to identify the reception completion signal in the third area of the memory unit 13, as shown in FIG. The transfer setting flag of 13C is rewritten to "0" (step 376), and when the transfer flag is "1", it is rewritten to "0" (step 3
77).

[0096] Then, the display control unit 1B of the control unit 1 displays the information that when the transfer mode display two-color LED 19 is lit in green, after it is turned off (
Step 378), this transfer mode display 2-color LED 19
is lit in red for several seconds, and the notification sound control unit 1C controls the notification sound generation unit 21, causing the notification sound generator 22 to generate a notification sound to notify the user that the call transfer mode has been canceled (step 379).

[0097] Here, if the user wishes to delete the transfer destination slave device PS number, he/she operates the setting key 16 once more.

That is, with the incoming call transfer mode canceled, it is checked whether there is any input from the setting key 16 (step 382), and if there is no input from the setting key 16, then
It remains in standby mode "1" (step 381).
, when the setting key 16 is input, the control unit 1 uses the memory control unit 1D to erase the transfer source PS number in the third area 13C of the memory unit 13, as shown in FIG. Rewrite the PS flag to "0".

[0099]

[Effects of the Invention] As explained above, the present invention allows the user (the person carrying the handset) to set the handset to call forwarding mode, so that even in the zone to which the handset is moving, the person carrying the handset can conduct a conference call with simple key operations according to the user's will. During free time, such as during breaks, there is a mode in which you can answer calls when the person's handset receives calls, and a mode in which you can answer calls when they are in a meeting, instead of letting the call come through to your handset. It has the advantage of being able to be used by switching between a mode in which the phone receives a call and the assistant responds in real time.

[0100]

As explained above, according to the present invention, in a state where the call transfer function is set by the call transfer function setting means, the first control unit that transfers an incoming call to the handset to the forwarding destination handset is configured. Since the configuration is configured such that the switching means can selectively switch between the incoming call control mode and the second incoming call control mode in which incoming calls to the handset are directly received by the handset, so even in the zone where the person is moving, With simple keystrokes, you can directly answer incoming calls to your own handset during free time, such as during breaks in a meeting, and if you are in a meeting and cannot answer an incoming call, the call will be sent to your own handset. The advantage is that you can have the assistant respond in real time by having the call arrive on the assistant's handset without having to wait.
