Description

Description: TECHNICAL FIELD The present invention relates to a telephone exchange system, and more particularly to a telephone exchange system including a telephone and an exchange for switching and connecting the telephone and a terminal device.

[Prior Art] Conventionally, a private branch telephone and an exchange for connecting and exchanging the same are
It is widely used in the same company organization or the same building. Each telephone connected to such a private branch exchange has a peculiar incoming call number, a so-called extension number, and an incoming call is made to each private branch telephone using this number. One private telephone is used by one or more users, but in a conventional switching system, when a user wants to talk with a user, the private telephone at the place where the user is supposed to be is called. Was called by the method. But,
It is good if the user of the relevant local telephone is near the telephone, but depending on the business contents, etc., the user may be moving to another room. In some cases, it was necessary to repeat the connection exchange with the telephone at the place where the user is now. That is, in the conventional exchange system, instead of "calling to the person who wants to call", "connecting to the place where the user is likely to be" was used.

On the other hand, from the standpoint of the person receiving the call, if you move from the place where your phone is with a well-known pager, you make a call using the destination phone. It is possible to call the other party back. However, even if a conventional pager knew that a call had been made, it had to ask the successor who received the call to see who was calling. Therefore, the conventional method using the pager has a drawback in that the call receiving side is burdened with a great deal, and since the transferee is required, the personal use is impossible.

[Objective] The present invention solves the above-mentioned problems. Even when the user is moving to another place, the user can immediately answer the incoming call and, as in the conventional case, the agent can be called. It is an object of the present invention to provide a telephone exchange system including a terminal device that does not require any complicated operation.

According to the present invention, in order to achieve the above object, in a telephone exchange device accommodating a plurality of extension telephones, in any one of the plurality of extension telephones, a portable telephone paired with the extension telephone is provided. A detecting means for detecting that a mode for calling the calling terminal has been set, and when the calling side requests the calling of the extension telephone set with the mode, the portable calling terminal paired with the extension telephone is wirelessly set. When a calling means for calling by a signal and the corresponding portable calling terminal are called, and the extension telephone set with the mode is off-hook, the calling side is connected with this extension telephone, and the mode is set. The extension telephone set which is different from the extension telephone set to which the mode has been set or the call corresponding to the mobile calling terminal paired therewith is set. Adopting a structure having an input and off-hook is made of numbers and the calling party and connecting means for connecting the extension telephone.

[Examples] Hereinafter, the present invention will be described in detail based on examples shown in the drawings.

FIG. 1 shows an embodiment of a telephone according to the present invention.
FIG. 1 schematically shows the upper surface of a private telephone. First

A numeric keypad 4 is provided on the upper surface of the housing 5 as in the case of a conventional touch-tone telephone or the like, and a call origination and an input / change operation of an incoming call number described later are performed via the numeric keypad 4. Two keys denoted by reference numerals 1 and 2 are provided above the numeric keypad 4.
The bell key 1 is composed of a switch element having a built-in display element such as a lamp, and a "bell" character is engraved or printed on the switch surface as shown in the drawing. The incoming key 2 is also composed of a switch element incorporating the same display element.

On the other hand, FIG. 2 shows the construction of a private branch exchange 50 for connecting and exchanging the telephones of FIG. 1 in the private branch. The exchange comprises a communication path system indicated by reference numeral 20 and a control system indicated by reference numeral 30. Reference numeral 24 or 25 in FIG.
What is indicated by is the telephone shown in FIG. The telephones 24 to 25 are each provided with a switch circuit network 21 in a communication path system 20 via a line circuit 26 for performing level exchange, etc., which is known.
Connected to. The switch circuit network of the communication path system 20 is composed of a large number of switch elements as in a known exchange, and connects the telephones corresponding to a given called number or the connection between the input side relay circuit and each telephone. Do.
The exchange and the external outside line exchange are connected via a known line circuit indicated by reference numeral 30 '. A publicly known monitoring circuit 29 for monitoring the connection exchange operation is connected to the switch network 21.

The operation of the switch elements of the switch network 21 is performed by the central processing unit 23 via a known switch control circuit 22 for converting a signal of logic level into a signal level capable of driving the switch element. The central processing unit 23 is composed of a well-known microcomputer element and the like, and has a memory 27 for storing a control program and an incoming call number input in a later-described incoming call number input / change operation. The central processing unit 23 is connected to a signal circuit via a signal transmission / reception circuit 28 which is a well-known interface circuit, and this signal circuit is used for exchanging control signals with an external exchange.

Next, FIG. 3 shows the overall configuration of the exchange system embodying the present invention, which comprises the above telephone, exchange, and pager device.

In FIG. 3, reference numeral 34 designates a telephone capable of inputting and changing the called number shown in FIG. 1, and 35 designates an extension telephone similar to the known one, which is the same as the digital exchange shown in FIG. Connected. The exchange 31 is connected to the exchange of the central office 36 in a known manner.

The exchange 31 also has a pager transmitter 32. The pager transmitter 32 calls a specific pager 33 based on a command from the digital exchange 31 and makes a bell sound. That is, in the embodiment of the present invention, the pager 33 has a unique incoming call number, and by dialing the number from the external or extension telephone set 35, the call is transmitted to the exchange 31 and the exchange 31 calls it. Based on the pager transmitter 32, the pager 33 is configured to ring.

In the present invention, the pager 33 and the bell key 1 shown in FIG.
Incoming number variable telephone with 24 (24 in Fig. 2 and 3 in Fig. 3)
Use 4) in pairs and assign them the same unique called number.

If the pager call mode is set by pressing the bell key 1 of the variable dialed number telephone, the pager will ring if a call is made using the common dialed number of the variable dialed number telephone and pager. . When the pager calling mode is released, a call can be made to this telephone by making a call using the common called number of the telephone with variable number and the pager.

In the present invention, the variable called number of the telephone is
Allow users to carry a pager and leave a paired phone, allowing them to temporarily use a different phone for the incoming call than the one paired with their pager This is because.

To change the called number of a called number variable telephone that is not paired with a pager, the procedure shown in FIG. 4 is used.

When a call is made through the exchange of the central office 36 or from an extension telephone in step S1 of FIG.
The telephone number called as digital information is input to 31.

The exchange 31 subsequently determines in step S2 whether the number called is a unique registration number assigned to the pager 33. If this step is denied, the procedure moves to step S3, and the extension is connected to the telephone line 34 or 35 by a normal connection operation.

If step S2 is affirmed, that is, if the called number is the unique called number of the pager 33, the process proceeds to step S4, and the pager 33 of the number is called via the pager transmitter 32. Send a signal and ring the pager 33 bell.

Here, if the owner of pager 33 notices the bell sound and the called number variable telephone paired with his pager is not in the vicinity, the owner changes the nearest called number variable in steps S5 and S6. Change the called number of phone 34. That is, in step S5, the pager owner goes to the nearest telephone 34, and in step S6, the incoming key 2 of the telephone shown in FIG. Change temporarily.

The operation is performed by first pressing the incoming call key 2 and then using the ten-key pad 4 to enter the incoming call number of the pager. As a result, in step S6, the telephone number of the pager is input from the telephone set to the central processing unit 23 of the exchange through the line circuit 26 of FIG.

In step S7, the central processing unit 23 collates the called number of the pager called and the called number of the called number variable telephone temporarily changed as described above. If the numbers match, a line connection is made in step S9, and an external line or an extension telephone that has called is temporarily connected to a telephone whose called number has been changed to make a call. The temporarily changed called number of the telephone is automatically restored to the original telephone number as described later.

If the numbers do not match in step S7, the connection may not be performed, but as shown in step S8, the incoming call number of the telephone is changed to the number input to the telephone thereafter. Any processing may be performed.

On the other hand, the bell key 1 of the telephone shown in FIG. 1 is used as follows. As mentioned above, one pager and a variable dialed number telephone set are paired and the same unique dialed number is assigned. When the bell key 1 is not pressed, the telephone is operated in the same manner as a normal extension telephone, and when the bell key 1 is pressed, as shown in the flow chart of FIG. Set the pager ringing mode to send ringing signals to the bell.

Here, FIG. 5 shows an example of the inter-station sequence in the above configuration in detail in relation to the control of the exchange. In FIG. 5, reference numeral 50 is the private branch exchange shown in FIG. 2, 51 is an ordinary telephone such as an external public telephone, and 24 is the above-mentioned variable number telephone. Here, illustration of the exchange of the telephone office is omitted.

In the example of FIG. 5, the two sequences shown by the reference numerals 52 and 53 are roughly divided.

First, the sequence 52 is a control when the general telephone 51 makes a dial call to the telephone set 24, and at that time, the telephone set 24 is already responding to the registration operation of pager call designation.

In response to a dial call, when the signal 24 indicating that the pager call mode has been set by operating the bell key 1 from the telephone 24 is returned to the exchange, the exchange transmits the pager 33 corresponding to the registered number. Call via machine 32.

During this time, the ringback tone 55 indicating that the pager is ringing is returned to the ordinary telephone 51. And at this time,
If the landline is hooked on, as shown at 56, the pager call is aborted, but if it is not hooked on, sequence 53 is entered.

The sequence 53 ′ of the sequence 53 is the step S5 in FIG.
Since this is the control for temporarily changing the called number shown in S7 and S9, detailed description thereof is omitted here. After this, a call is made as indicated by reference numeral 57. Here, the reference numeral 24 'designates the nearest telephone to which the user of the telephone 24 moves.

Thereafter, recovery and line disconnection operations are performed in the sequence 53 ″, but this process is the same as the line hold and disconnection process in the publicly known constituent exchange, and therefore its explanation is omitted.

Further, after this restoration sequence 53 ″, the exchange 50 returns the called number of the telephone set 24 ′ to the original one.

Here, among the operations of the central processing unit 23 in the exchange, the operations at the time of circuit switching will be briefly shown in FIG.

If there is a hook-off from the ordinary telephone in step 61, the dial tone is returned in step 62 as usual, the dialed number is received in step 63, and the call is made in step 64.

Next, if it is assumed in step 65 that the other party at this time is a telephone with a variable called number and that the pager call button has been pressed, a signal is received accordingly and the process proceeds to step 66, and the pocket corresponding to that number is received. Instruct the originating station to ring the bell. In other cases, normal processing is performed.

Here, as shown in FIG. 4, when the person called by the pager turns to the nearest variable telephone number that is not paired with his / her pager and changes the called number, the step is performed. Proceeding from S67 to S68, the called number of the telephone is temporarily rewritten, and the telephone can respond (step S69). When the telephone paired with its own pager is taken off-hook, the telephone paired with its pager can answer directly at step S69.

As described above, if the bell key 1 is pressed and the pager device is carried and moved, the operator can carry out a troublesome call to himself by using the other variable number telephones by the above-mentioned operation. You can receive a call without performing any operation. According to the present embodiment, it is possible to operate and use the exchange system on an individual basis without requiring a takeover person for the pager as in the past.

In the above-mentioned embodiments, for simplification of the description, the embodiment relating to the premises telephone is shown, but the present invention can be applied to a general telephone exchange system. For example, it is conceivable to use the variable called number telephone of FIG. 1 for a public telephone or the like.

Even if the user is carrying a pager, it is possible that the phone will take a considerable amount of time to reach the phone.Therefore, when calling the pager, a special signal sound or voice signal is sent to the caller to express that effect. It may be returned as the ringback tone 55 in FIG. Even if the calling side hangs up, the pager calling may be continued until the called side outputs an incoming signal, and then the calling side may be called. This makes it possible to receive calls even when you are out, without the need for an answering machine. Other than the pager, a child phone of a parent-child phone may be used.

[Effect] As described above, according to the present invention, a mobile calling terminal paired with an extension telephone is used, and a mode for calling the paired mobile calling terminal is set for the extension telephone to make a call. When requested by the caller, the mobile calling terminal paired with this extension telephone is called by a radio signal, and when the extension telephone set to the calling mode of the mobile calling terminal is off-hook, the calling side and this extension telephone are connected. While connected, an extension telephone set different from the extension telephone set in the mode is issued when an incoming telephone number corresponding to the extension telephone set in the mode or a mobile calling terminal paired with the extension telephone is input and off-hook is performed. Since this extension telephone on the calling side is connected, when a user uses one extension telephone and one mobile calling terminal, the mobile calling terminal calls When you get out, you can easily answer by off-hooking your extension phone if you are near your seat, and if you are not near your seat, you can use another extension It is possible to provide an excellent telephone exchange device that can respond by inputting and off-hook, does not require a transfer person and troublesome operation, and can be easily operated.
