Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, the present invention will be described as a preferred embodiment of an external call forwarding apparatus and method for enabling direct connection with a call requester requesting a telephone call by enabling and disabling call forwarding using an external telephone. The technical spirit of the present invention is not limited thereto, but may be variously modified and modified by those skilled in the art.

Figure 1b is a view for explaining the overall configuration of the external call forwarding apparatus according to the present invention, Figure 2 is a block diagram showing an embodiment for explaining the detailed configuration of the external call forwarding apparatus according to the present invention .

First, as shown in FIG. 1B, a signal and a caller ID (for example, the number of the mobile phone 400) for identifying the call forwarding from the second telephone 102 for which the caller ID is to be set are called. After receiving the input to the device 500, and transmits the user authentication guide message from the external call forwarding device 500 to the second telephone (102).

Then, the external telephone call forwarding device 500 checks the user authentication by comparing the password inputted from the second phone 102 through the user authentication guide message with the previously stored user authentication password, and when the user authentication is confirmed, the exchanger The incoming call forwarding signal (for example, # 880183320000 *) is transmitted to 200.

On the other hand, when the switch 200 receives the call forwarding signal, the call requester requesting a phone call from the third phone 100 by changing the switching to the switch network (ie, the mobile phone 400 of the called number). }

Referring to Figure 2, the external call forwarding device 500 supports to enable and disable call forwarding using an external telephone (second telephone in the present embodiment).

First, the receiving unit 510 receives a ring signal from the external telephone (second telephone 102 in the following description) through the switch 200.

Then, the signal counter 515 counts the ring signal transmitted from the receiver 510.

The controller 520 determines whether the ring signal counted by the signal counter 515 exceeds a predetermined number (for example, seven times). If the predetermined number is not exceeded, the standby state is maintained, and if the predetermined number is exceeded, the voice addresser 540 is instructed to output the corresponding address.

The voice memory (EPROM) 541 outputs a digital signal corresponding to the first guide message stored at the corresponding address output from the voice address counter 540 to the voice synthesis LSI 542.

The speech synthesis LSI 542 synthesizes a digital signal corresponding to the first guide message output from the speech memory (EPROM) 541 into an electrical signal and transmits the digital signal to the filter 543.

The filter 543 filters the synthesized signal transmitted from the speech synthesis LSI 542 and transmits it to the second telephone 102 through the exchange 200. The filtered first guide message is, for example, "I'm out now. To leave a message, enter 1; to leave a phone number; enter 2; to enter a call; enter 0; It can be a prompt such as "Press."

Thereafter, the controller 520 determines whether a button signal is received from the second telephone 102 which is the external telephone. As a result of the determination, when no button signal is received from the second telephone 102, the controller waits for a predetermined time.

On the other hand, when the button signal is received from the second telephone 102, the control unit 520 is a key signal stored in the key signal memory (RAM) 535 and the button signal input through the second telephone 102 In comparison, if a button signal corresponding to a call forwarding request is input from the second phone 102, the second guide message is controlled to be transmitted. The second guide message may be, for example, "Enter the forwarding number to be forwarded and press the pound sign #".

Again, when the called party number is input from the second phone 102, the controller 520 enters a third guide message (for example, "Password" into the second phone 102, and the pound sign #). Press "), and enter the user authentication password and check the user authentication by comparing with the previously stored user authentication password.

The controller 520 generates a call forwarding signal using the called number input from the second phone 102 in which user authentication is confirmed, and outputs the generated call forwarding signal to the transmission unit 560. The call forwarding signal is a special code (for example, # 880183320000 *) including a call forwarding request phone number.

The transmitter 560 transmits a call forwarding signal output from the controller 520 to the switch 200.

The controller 520 may set and release the called number transmitted to the switch 200 through the transmitter 560 according to the operation of the second telephone 102 whose user authentication is confirmed.

Then, the third phone 100 requesting a phone call is connected to directly communicate with the user's mobile phone 400, which is a phone corresponding to the called number transmitted to the switch 200.

In addition, a signal (for example, well #) and a call designation number (for example, 88) for identifying a call forward from the second telephone 102 are inputted, and then the number to be forwarded (for example, 0183320000) and a call completion button signal {for example, an asterisk (*)}, a third guide message to the second telephone 102 ("Enter the password, press the pound sign #") Send it. However, in this case, it is more preferable to make it possible to recognize that the call forwarding is intended even if only the telephone number and the "#" button to be called from the second phone are pressed.

3A and 3B are flowcharts illustrating an external call forwarding method according to the present invention.

First, the receiver 510 receives a ring signal from the second telephone 102 to set a called number, and the signal counter 515 counts the received ring signal (S102).

The controller 520 determines whether the ring signal counted through the signal counter 515 exceeds a predetermined number of times (S104). As a result of the determination in S104, if the ring signal does not exceed the predetermined number of times, the standby state is maintained.

As a result of the determination of S104, when the ring signal exceeds a predetermined number of times, the controller 520 sends a message from the voice memory (EPROM) 541 to " now going out. &Quot; In order to forward call 2, enter 0, and press the well sperm (#) to transmit the first guide message, such as "," and transmit it to the second telephone 102 (S106).

The controller 520 determines whether a button signal is received from the second telephone 102 through the first guide message (S108). As a result of the determination in S108, when the button signal is not received from the second telephone 102, a predetermined time is delayed (S110).

As a result of the determination in S112, when the button signal "1" is input from the second telephone 102, the control unit 520 receives the button signal from the key signal memory (RAM) 535, and then, From the voice memory (EPROM) 541, a prompt message, such as "Enter a message when the beep sounds, press the well sperm (#)" corresponding to the button signal 1, is sent, and the sent message is sent. After transmitting to the second phone 102 through the same process as described above, the voice message is received from the second phone 102, the received voice message is stored in the voice memory 530 (S114) do.

As a result of the determination in S112, when the button signal "2" is input from the second telephone 102, the controller 520 receives the button signal 2 from the key signal memory (RAM) 535, From the voice memory (EPROM) 541, send a message such as "Enter the phone number to be contacted and press the pound sign (#)" corresponding to the button signal # 2, and the message sent from above After passing through the same process as described above to the second telephone 102, the telephone number is received from the second telephone 102, and the received telephone number is stored in the voice memory 530 (S116). .

As a result of the determination in S112, when the button signal "0" is input from the second telephone 102, the controller 520 receives the button signal 0 from the key signal memory (RAM) 535, From the voice memory (EPROM) 541, the second guide message corresponding to the button signal "0, enter the incoming call number and press the well sperm (#)" corresponding to the 0 button signal is sent. The message is transmitted to the second telephone 102 through the same process as described above (S118), and then the telephone number to be received from the second telephone 102 is stored in the voice memory 530 (S120).

When the request signal for identifying the completion of the incoming call number input is input from the second phone 102, the control unit 520 may perform a "Call Forwarding" operation to the second phone 102. After inputting the password, Press (#) "to transmit and transmit the third guide message from the voice memory (EPROM) 541 (S122).

Thereafter, the controller 520 receives a password from the second phone 102 according to the transmitted third guide message (S124), and then compares the received password with a previously stored password to determine whether the password matches the previously stored password (S124). S126).

As a result of the determination in S126, if the password inputted from the second telephone 102 does not match, the process proceeds to S122 where the controller 520 enters " now entered from the voice memory 530. " The message may be sent to the second telephone 102.

As a result of the determination in S126, when the password input from the second telephone 102 is matched, the controller 520 generates the call forwarding signal (for example, # 880183320000 *) (S128), and generates The incoming call transfer signal is output to the transmission unit 560.

The transmitter 560 transmits a call forwarding signal from the controller 520 to the switch 200 (S130).

The controller 520 transmits a call forwarding success beep to the second telephone 102 (S132).

Then, the third phone 100 requesting a phone call is connected to directly communicate with the own mobile phone 400 corresponding to the called number transmitted to the switch 200.

On the other hand, the controller 520 is recording a voice message from the third telephone 100, when a separate hook input signal from the personal telephone 300, the personal telephone 300 from the third telephone 100 You also need the ability to pass voicemails.

In addition, upon receiving the call forward release signal and the password from the second telephone 102, a function of transmitting a call forward release signal (for example, * 88 *) to the switch 200 is also required.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited to the drawing.
