The plurality of key phone telephones 20-22 connected to the key phone telephone controller 10 through an extension are user terminals, and the key phone 20-22 includes a key having a plurality of input keys including an outing key, a release key, and a bell key. Through the input unit 20b-22b, the user outputs a dial signal to the telephone exchange station 2 via the telephone line controller 10 to the trunk line and makes a voice call with the other party connected through the handset. In addition, the key phone telephone 20-22 converts the key signal of the key input unit 20b-22b into a dial tone signal and transmits it to the key phone telephone controller 10 or receives a ringing tone or control received from the key phone telephone controller 10. Control units 20a to 22a driven by signals are included.

In addition, the memory unit 14 configured in the key phone telephone controller 10 may be configured in the key phone telephone 20-22 so that the information can be stored and transmitted from the key phone telephone 20-22.

The key phone telephone system according to the present invention can be applied wherever a key phone telephone controller 10 and a key phone telephone 20-22, such as a general office or a public office or a hotel, are used.

A method of connecting a telephone in the absence of the key-phone telephone user of the present invention configured as described above will be described with reference to FIGS. 4A to 4C.

First, the user of the key phone 20-22 is a key phone to transfer the incoming call to the user's key phone 20-22 to the desired phone, mobile phone or pager 30 when out, on a business trip or while away The telephones 20-22 must be set up. In this case, by setting the ring tone to be connected after a predetermined number of times or by setting the call to the desired telephone or mobile phone or pager 30 immediately after the call transfer is made without the ring tone, the user selection function is provided.

For this call forwarding, the following steps (S200) to (S208) must be passed. That is, in step S200, the user inputs the outing key configured in the key input unit 20b-22b of the corresponding key phone telephone 20-22. At this time, the control unit 20a-22a of the key phone 20-22 determines whether there is an input of the outgoing key. If there is an input of the outgoing key, it is determined whether there is a bell key input after the outgoing key is input in step S201, and if there is an input of the bell key, a voice message regarding how many times a ring tone is generated is sent in step S202. Let's do it. For example, the voice message "Please enter the number of rings" is sent. At this time, the user sets about 3 to 10 times, and a preferable setting frequency is 5 times.

In step S203, the user inputs the desired number of rings to be set through the key input unit of the corresponding key-phone telephone 20-22, and sets in step S204 whether the input for the number of rings is generated. This determination is made by inputting a key (for example, # or * key) indicating that the input is completed after inputting a numerical value relating to the number of rings.

On the other hand, if there is no input of the bell key in step S201, the control unit 20a-22a in step S205 receives the voice message stored in the memory unit 14 of the key phone telephone controller 10 via an extension to the built-in speaker Output through At this time, the voice message is sent, for example, "Enter a phone number to contact", the user inputs the phone number of the telephone, mobile phone or pager 30 that can be received while out in step S206. In addition, in step S207, the user determines whether the input of the telephone number is completed, and the user must press a predetermined key configured in the key input units 20b-22b after completing the input of the telephone number. That is, for example, when the # key or the * key is pressed at the end of the input phone number, it is recognized that the input of the phone number is completed. This can be set at the time of manufacture of the key-phone telephone controller 10 or can be set arbitrarily by the user.

In step S208, the telephone number inputted to the key input unit 20b-22b of the key phone telephone 20-22 is stored in the memory unit 14 of the key phone telephone controller 10 via an extension. 14) is stored as a dial tone signal or converted to a predetermined digital signal and stored. At this time, the memory unit 14 also stores the information of the key-phone telephones 20-22 for inputting the current telephone number. That is, for example, if the user of the first key phone 20 enters a phone number to transfer the call while not in the absence, the memory unit 14 is absent from the user of the first key phone 20, and the first key phone 20 is not present. In order to be able to connect the incoming call to the key-phone telephone 20 to the stored phone number.

In this way, the setting for the call forwarding is completed so that the incoming call to the corresponding key phone phone 20-22 is connected to the desired phone or mobile phone or pager 30.

After the setting of the corresponding key phone telephone 20-22 is completed, it is determined in step S209 by the key phone control unit 12 of the key phone telephone controller 10 whether there is an incoming call from the telephone exchange station 2 via the trunk line. In this case, it is the same as the general telephone standby state of the key phone telephone controller 10.

If there is an incoming call from the trunk line, the corresponding phone phone 20-22 rings immediately to receive the ringing tone set in advance in the key-phone telephone controller 10. If the handset is in the on state after ringing the corresponding phone phone 20-22 in step S210, and it is in the on state, it is determined whether the extension switch key has been input in step S211. At this time, if the user who answers the call while the handset is on maintains a call with the called party and wants the other party to switch to the desired user, the user enters the extension key, but the extension key is input. In the non-state state, if the handset is in the off state after the telephone call is made with the user of the key ring telephone 20-22 ringing in step S212, the call is blocked and the call is terminated.

However, when the extension key is input in step S211, it is determined whether the keypad phone 20-22 connected to the input extension is set to missed, and the extension key matches the telephone key in the absence state. In this case, it is determined whether there is a setting of a bell key in step S215, and a set number of rings to be generated when there is a setting for the bell key in step S216.

On the other hand, if there is no setting of the bell key in step S215, and the corresponding key phone telephone 20-22 connected to the switched extension is set to missed, the phone number stored in the memory unit 14 is dialed in step S219. Will dial. At this time, in step S220, after transmitting a message to the other party during dialing, the melody sound is transmitted while being connected. That is, for example, the set melody sound is sent after the message “Please wait” and “Connecting” is sent. In addition, when the memory unit 14 is connected to the telephone number memorized in the step S221, it makes a connection with a waiter or receives a service operated by a corresponding communication service provider. For example, if the inputted phone number is a pager, a phone number or a message may be left by a service of a corresponding carrier, and in the case of a mobile phone, a direct call or a guide service may be received. This telephone connection is connected to the corresponding telephone or mobile phone or pager 30 by transmitting the telephone number stored in the memory unit 14 from the key phone control unit 12 of the key phone telephone controller 10 to the telephone exchange station 2 through the trunk line. Will let you.

In addition, when the corresponding telephone phone 20-22 is not set to the missed state after the extension key is input in step S213, a ring tone of the corresponding phone phone is generated in step S214. In addition, it is determined whether the handset is switched on in step S217 while the ring tone set in step S216 is generated. At this time, if the handset is turned on, the call is terminated by turning off the handset after the telephone call is made in step S218.

On the other hand, if there is no input of the outgoing key in the step (S200), it is determined whether there is an input of the release key in the step (S222), the input of the release key whether the user of the corresponding key phone phone to the input of the outgoing key After setting the phone number to be contacted by the user to enter the purpose of releasing the set phone number, if there is no input of the outgoing key and the release key to maintain the initial state.

Therefore, if there is an input of the release key in the step (S222), the information on the corresponding phone phone 20-22 and stored in the memory unit 14 of the phone key key phone telephone controller 10 in the step (S223) Will be judged. If there is a telephone number stored in the memory unit 14, the corresponding telephone number and information on the key-phone telephone 20-22 in step S224 are deleted and then, for example, "deleted" in step S225. Is displayed. In addition, when there is no stored phone number in the step S223, for example, the message "There is no stored phone number" is sent out.

As described above, according to the present invention, a user who uses a keyphone telephone, which is a terminal communication medium connected to the keyphone telephone controller in an office, a government office, a hotel, or the like by extension of an extension, is called a predetermined number of rings immediately or absent. To make a connection after the ringing, set the phone number of the telephone, mobile phone or pager to be received through the corresponding keyphone telephone in the memory of the keyphone telephone controller, and set up call forwarding from the keyphone telephone controller through the extension. When a call is connected to a keyphone phone, the user of the keyphone phone can be contacted by a desired phone, mobile phone or pager when the user is absent, so that the person who is calling the keyphone phone system is waiting for an unauthorized call waiting. I can solve it In the case of a long-distance call, an international call or a mobile phone, the call charge can be reduced by the waiting time, and the location of the user who wants to call can be grasped.
