Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a telephone device having a transfer function.

[0002]

2. Description of the Related Art Generally, a PHS slave unit can be used as a cordless slave unit at home, and can also be used as a portable terminal outside a home. That is, when used at home, a self-operated base station is installed in the home as a base unit, and the PHS slave is used in a self-operated mode. In this case, the PHS handset performs a call or communication via a self-owned base station (master) in the home. When the PHS slave is used outside the home, it is used in the public mode. In this case, the PHS slave performs a call or communication via the nearest public base station.

By the way, some telephone devices such as PHS handsets accommodating wireless telephones and telephone devices such as wired telephones have a transfer function. These telephone devices
A call destination is specified in advance, and when an incoming call arrives, the call is answered once and then transferred to the transfer destination telephone, or
The telephone number of the transfer destination telephone is dialed using another line, and when the transfer destination telephone answers, the called line is answered and the destination line and the transfer destination telephone are connected.

[0004]

In a telephone device having such a transfer function, when a transfer destination is set to a terminal such as the PHS slave, an incoming call is received when the terminal is in the public mode. However, there is a problem that incoming calls cannot be transferred when the mobile phone is in the private mode. That is, if the terminal is set as a transfer destination in a home telephone device (parent device) accommodating the terminal and the user goes out of possession of the terminal, a public mode is set. The call is automatically answered once by the master unit, and is transferred to the corresponding terminal via the route of the master unit, the exchange, and the public base station. However, when the user who owns the terminal returns home, the terminal enters the self-employed mode.At this time, the base unit receives an incoming call, and even if the base unit tries to transfer the incoming call through the above route, the terminal is determined to be out of the range of the public base station And cannot forward calls.

[0005] Further, even if this terminal can cope with both the public mode and the self-operating mode, in the self-operating mode, there is a problem that the efficiency is low because the master unit once answers the incoming call and then transfers it to the terminal. there were. Therefore, an object of the present invention is to transfer an incoming call to a corresponding transfer destination terminal accurately and efficiently when a terminal designated as a transfer destination is in a private mode.

[0006]

SUMMARY OF THE INVENTION In order to solve such a problem, the present invention is capable of accommodating terminals operating in a public mode and a private mode, and in which an incoming call arriving at an accommodated outside line is designated. A telephone device for transferring a call to a transfer destination is provided with transfer means for transferring the call to the terminal based on the current mode of the terminal specified as the transfer destination when the arrival of the call to the outside line is detected. Further, in a telephone device capable of accommodating terminals operating in the public mode and the private mode, and performing a transfer process of transferring an incoming call arriving at the accommodated outside line to the terminal, setting a transfer state when an incoming call to the outside line arrives First determining means for determining whether or not the terminal designated as the transfer destination when the transfer state setting is determined by the first determining means is in the self-employment mode. And a calling means for stopping the transfer process when the second judging means judges that the mode is the self-employed mode and calling the terminal. Further, when the terminal does not respond to the call of the calling means even after the elapse of a predetermined time, an incoming call notifying means for notifying the connected terminal other than the terminal of the incoming call is provided. Also,
If the second determination means determines that the terminal is in the self-employment mode, a transfer means for stopping the transfer processing and calling all connected terminals is provided.

FIG. 2 is a block diagram showing the structure of the public base station 3. The public base station 3 includes a radio unit 31, a modem unit 32, a channel codec unit 33, and a memory 34A.
A line control unit 34 for controlling the line L, and a voice processing unit 39.
Is connected to the exchange 100. The public base station 3 is wirelessly connected to a later-described wireless terminal via the wireless unit 11 and the antenna AT.

FIG. 3 is a block diagram showing a configuration of the terminal 5 wirelessly connected to the base unit 1 shown in FIG. 1 and the public base station 3 shown in FIG. The terminal 5 is, as shown in FIG.
1, a modem unit 52, a channel codec unit 53, a control unit 54 including a memory 54A and a CPU, a voice processing unit 59, and the like. The master unit 1 and the public base station 3 are connected via a radio unit 51 and an antenna AT. Wirelessly. Here, the microphone 62 and the receiver 63 are connected to the audio processing unit 19. Further, the control unit 54 is connected with a display unit 55, an operation unit 56 such as a dial key, and a buzzer 57 that sounds a ring when an incoming call is received.

The terminal 5 detects the frame from the base unit 1 in the area (area) of the base unit 1 and enters the self-operating mode. When the terminal 5 moves to the area of the public base station 3, the terminal 5 detects the frame from the public base station 3. In the public mode, the switching between the private mode and the public mode is performed by the private / public switching section 54 of the control section 54.
B.

By the way, the base unit 1 shown in FIG. 1 has a call function and a transfer function as described above, and can designate the terminal 5 as a transfer destination terminal.
That is, when the user operates the operation unit 16 and inputs the telephone number of the terminal 5, this is stored in the memory 14 as the transfer destination number.
A is stored. Here, when the terminal 5 is within the range of the base unit 1, the terminal 5 operates in the self-owned mode. However, when the user goes out of the public base station 3 while holding the terminal 5, the terminal 5 becomes self-owned. From mode to public mode. When there is an incoming call at the base unit 1 at this time, the base unit 1 once answers the incoming call, causes the recording unit 20 to record a message on the calling side, and then re-acquires the line L to recall the memory 14A.
By dialing the transfer destination number (telephone number of the terminal 5). Then, a call is made from the public base station 3 to the terminal 5, and when the terminal 5 answers, the base unit 1 reproduces the calling side message of the recording unit 20 and transmits it to the terminal 5. In this way, the incoming call is transferred to the terminal 5.

On the other hand, when the user carrying terminal 5 returns home and returns to the area of base unit 1 with terminal 5 as the transfer destination, terminal 5 enters the self-employed mode. When an incoming call arrives at base unit 1 at this time, base unit 1 sets channel codec unit 13,
The terminal 5 which is the transfer destination terminal is called via the modem unit 12, the radio unit 11, and the antenna AT. When terminal 5 answers the call, base unit 1 connects the answering line to terminal 5 in response to the incoming call. This allows the incoming call to go to terminal 5
Transferred to

FIG. 4 is a flowchart showing the operation of the control unit 14 of the base unit 1 for performing such call transfer. The operation of the main part of the present invention will be described in detail according to this flowchart. In step S1, detection of the arrival of an incoming call from any of the lines via the line control unit 18 is determined. When an incoming call arrives, whether or not a transfer state has been set is determined in step S2 by detecting whether or not a transfer destination telephone number has been set in the memory 14B. Here, if the transfer destination telephone number has been set, “transfer state?” In step S2 is determined to be “Y”, and the process proceeds to step S3.

In step S3, a determination is made as to "is the transfer destination its own child device?" Here, the memory 14A of the control unit 14
The telephone number of the terminal 5 is set beforehand in addition to the transfer destination telephone number. In step S3, the telephone number is compared with the transfer destination telephone number, and if the preset telephone number matches the transfer destination telephone number, the determination of "is the transfer destination itself?" In step S3 is "Y". Becomes In this case, the control unit 14 subsequently determines in step S4 whether the terminal 5 is in the self-employment mode.

Here, when the terminal 5 is located within the service area of the base unit 1, the terminal 5 enters the self-operating mode as described above, and the base unit 1 registers the position of the terminal 5 and informs the memory 1
4A, the determination of “Self-employed mode?” In step S4 is “Y”. Then, the control unit 14
Displays the self-operating mode of the receiving terminal 5 on the display unit 15 in step S5, and displays the channel codec unit 13, the modulation / demodulation unit 12, and the radio unit 11 to the terminal 5 as the transfer destination handset in step S6. And a call via the antenna AT (that is, a call via a wireless line). When the terminal 5 responds to the call, the control unit 14
Controls the line control unit 18 to respond to the incoming line L. As a result, a call is started between the terminal 5 and the calling side. In this way, even a terminal in the self-employed mode can accurately transfer a call to the terminal. Further, at the time of this transfer, the terminal 5 responds to the incoming call of the line L only after responding to the call, so that the line usage fee associated with the transfer can be eliminated.

If the response of the terminal 5 cannot be detected even after the lapse of the predetermined time, all the telephones are called in step S7. That is, in this case, the base unit 1 capable of making a call
Buzzer 17 is ringed to allow incoming call to be answered by base unit 1, and when base unit 1 is connected to the main unit of the key telephone apparatus, line L (in this case, line L is (Which becomes a transmission line between the main unit) and the incoming data to the main unit, and all the key telephones connected to the main unit ring. Further, the call to the terminal 5 and the ringing of the incoming calls of all the other telephones may be performed simultaneously.
At this time, only a preset telephone among all telephones other than the terminal 5 may be set to ring.

Further, if the incoming call response of the telephone cannot be detected for a predetermined time, the control unit 14 of the base unit 1 controls the line control unit 18 to automatically respond to the incoming call, and the recording / reproducing control unit 21 May be transmitted from the recording unit 20 to the calling side, and then the recording unit 20 may record the message of the calling side.

By the way, when the incoming call arrives, the transfer state is not set and the judgment in step S2 in FIG.
In the case of, a normal incoming call process for ringing the buzzer 17 of the base unit 1 is performed in step S8. If the base unit 1 does not have a call function, the incoming data is sent to the terminal 5 to make the buzzer 57 of the terminal 5 ring. When the transfer state is set when a call arrives and the call is transferred to another transfer destination other than the terminal 5, the determination in step S3 is “N”.
In this case, the control unit 14 proceeds to step S9 and performs a transfer process. That is, dialing is performed to send the transfer destination telephone number set in the memory 14A to the line side, and a call is made to the transfer destination corresponding to the transfer destination telephone number. Also,
When the incoming call is forwarded to the terminal 5 when the incoming call arrives, the terminal 5 is not in the area of the base unit 1, so that the self-operating mode in step S4? Becomes "N", a transfer process is similarly performed in step S9. The terminal 5 is called by this transfer process.

Here, there are two methods for the transfer processing performed in step S9. The first transfer method is applied to a case where only one line is accommodated in base unit 1. In this case, control unit 14 controls line control unit 18 to respond to the incoming line, and Control the recording unit 20
Then, a message of the calling side via the line and the voice processing unit 19 is recorded. After the caller's message is thus recorded, the line is disconnected, and then the line controller 21 is controlled to recapture the line, dial the transfer destination telephone number stored in the memory 14A and dial the dial signal. Send to line. As a result, a call is made to the transfer destination. When a response to the call of the transfer destination is detected, the message of the recording unit 20 is reproduced and transmitted to the line via the voice processing unit 19. In this way, the incoming call from the calling side is transferred to the transfer destination, and the transfer destination can listen to the message from the calling side.

Next, the second transfer method is a method applied when a plurality of lines are accommodated in the base unit 1. In the second transfer method, first, when an incoming call arrives at a first line among a plurality of lines, a transfer destination is called using the second line. Then, when the transfer destination answers this call, the first line and the second line are connected. That is, if an incoming call arrives on the line L1 in FIG. 1, and a telephone number other than the own handset (terminal 5) is set as a transfer destination at that time (in the case of "N" in step S3 in FIG. 4), Alternatively, when the terminal 5 is set as the transfer destination and the terminal 5 is in the public mode (“N” in step S4 of FIG. 4), in the transfer process of step S9, the control unit 14 of the base unit 1 Part 18
To capture the vacant line L2 and dial the destination telephone number stored in the memory 14A to make a call to the line L2.
2 to output a dial signal.

The dial signal is transmitted to the exchange 100
The call to the transfer destination corresponding to the telephone number is performed by being transmitted to the telephone number. That is, when a telephone number other than the terminal 5 is set as the transfer destination, a call to the telephone according to the telephone number is performed. When the transfer destination is the terminal 5 in the public mode, a call is made from the public base station 3 to the terminal 5 via the exchange 100. And the control unit 14
When detecting the response of the telephone or the public mode terminal 5, the line control unit 18
1 and the line L1 and the line L2 that responded are connected. As a result, the calling side and the transfer destination are connected. In this way, the transfer processing of step S9 is performed. The present invention is not limited to the first and second transfer methods, but can be applied to other transfer methods.

When the terminal 5 designated as the transfer destination changes from the public mode to the private mode, the transfer state is automatically canceled, and when the terminal 5 designated as the transfer destination changes from the private mode to the public mode, the transfer mode is automatically reduced. The transfer state may be set as desired.

[0024]

As described above, according to the present invention, it is possible to accommodate terminals operating in the public mode and the private mode, and to transfer incoming calls arriving at the accommodated external line to a designated transfer destination. When the device detects an incoming call to an outside line, it transfers the incoming call to the terminal based on the current mode of the terminal specified as the transfer destination. In this case, the incoming call can be accurately and efficiently transferred to the corresponding transfer destination terminal. Also, when the incoming call to the outside line arrives, it is determined whether or not the transfer state is set, and when the transfer state is determined, it is determined whether or not the terminal designated as the transfer destination is in the self-employed mode. If it is determined that the call has been forwarded, the transfer process is stopped and the call to the corresponding terminal is performed, so that the incoming call can be transferred to the corresponding transfer destination terminal accurately and efficiently. Also, when the terminal does not respond to the call of the calling means even if the predetermined time has elapsed, the incoming call is notified to the other connected terminal. Therefore, even if the transfer destination is absent, the incoming response is received on the other connected terminal side. can do. Further, when it is determined that the terminal is in the self-employed mode, the transfer process is stopped and all the connected terminals are called, so that any one of the terminals can respond to the call.
