Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial application field) The present invention provides a method of calling a terminal for which transfer registration has been performed through an attendant console, depending on the situation. The present invention relates to a relay call control system that can be called by any terminal.

(Prior Art) As is well known, some key telephone systems call a target extension terminal through a relay console in response to a call from a central office line or the like.

Usually, a telephone with a DSS (extension direct selection) function is used as a relay console of this type of key telephone system.

This DSS function-equipped telephone has a DSS console provided with each DSS key corresponding to an extension terminal, and the extension terminal can be called by pressing the DSS key corresponding to the intended extension terminal.

In addition, this type of telephone with a DSS function generally has an attendant telephone attached to the above-mentioned DSS console, and the extension terminal is similarly called by dialing a number corresponding to the intended extension terminal. It is configured so that it can be put out.

Hereinafter, the former will be referred to as the DSS calling mode and the latter will be referred to as the dial calling mode for convenience.

On the other hand, some terminals accommodated in this type of key telephone system have a so-called transfer registration function for transferring a call to one's own terminal to another terminal registered in advance.

As is well known, the transfer registration function means that, for example, terminal A
Is a function to make a call to the terminal A from an extension or the like to the terminal B when the transfer registration to the terminal A is performed.
Is referred to as a transfer destination terminal.

In this type of conventional key telephone system, when a target terminal is called through a telephone with a DSS function (hereinafter, referred to as an attendant console) capable of selectively setting the DSS calling mode and the dial calling mode as described above, the sixth step is performed. Relay call control was performed by the method as shown in the figure.

For example, when a request to call a terminal occurs in response to an incoming call from another extension in the system (step 100),
The attendant console sets either the DSS calling mode or the dial calling mode described above,
A target terminal is called (step 101).

At this time, the control unit determines whether or not the target terminal (called terminal) has performed transfer registration (step 102). If the transfer registration has not been performed, the call is sent to the called terminal as it is. Incoming call is received (step 103). If transfer registration is performed, incoming call is made to the transfer destination terminal (transfer registration source terminal) (step 104).

As a result, the call receiving terminals for each call mode according to the presence / absence of transfer registration in the conventional relay call control method can be arranged as shown in FIG.

As is apparent from FIG. 7, in the conventional relay paging control method, regardless of whether the terminal paging process in step 101 is performed in the DSS paging mode or in the dial paging mode, the called terminal is transferred. During registration, the call always arrives at the transfer destination terminal.

For this reason, even if the operator performs transfer registration at a certain terminal, adds errands at the transfer destination terminal side, returns to the transfer registration source terminal side again, and the transfer registration source terminal can already answer the incoming call. Regardless, if you forget to cancel the transfer registration, the call from the attendant console to the transfer registration source terminal always arrives at the transfer destination terminal. became.

(Problems to be Solved by the Invention) As described above, in the above-described conventional relay call control method, a call from a relay console to a terminal for which transfer registration is performed always arrives at a transfer destination terminal. If the operator forgets to cancel the transfer registration, there is a problem in that the operator cannot answer the call forever, even though the operator is ready to receive a call at the transfer registration source terminal.

The present invention has been made in view of the above situation, and even when an operator who has performed transfer registration at a certain terminal returns to the terminal again and forgets to cancel the transfer registration, even if the operator has forgotten to cancel the transfer registration, the transfer from the relay console can be performed. An object of the present invention is to provide a relay paging control system that can reliably transfer a telephone call to the operator by paging control.

[Constitution of the Invention] (Means for Solving the Problems) The call control method of the present invention provides a direct call mode for calling the telephone terminal by a pressing operation of a one-touch key corresponding to the telephone terminal, and a telephone corresponding to the telephone terminal. Calling telephone terminal that can select a dialing mode for calling the telephone terminal by dialing based on the number, and transfer registration that can be registered and set for the telephone terminal to transfer the called telephone terminal to a third telephone terminal Means for judging whether or not the call is in the dial call mode when the calling telephone terminal calls the called telephone terminal for which transfer registration is set. If the result of the determination is that the call is in the dialing mode, the transfer source called terminal is called regardless of the transfer registration corresponding to the called terminal. And it is characterized in Succoth.

(Operation) According to the call control system of the present invention, if the call is in the dial call mode, the called telephone terminal of the transfer source is called without depending on the transfer registration corresponding to the called telephone terminal, and depending on the situation. The above object is achieved by making it possible to call either the transfer destination telephone terminal or the transfer registration source telephone terminal.

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

FIG. 1 is a block diagram showing one embodiment of a key telephone system according to the present invention, wherein 1a to 1n are terminals, 2 is a telephone with a DSS function, 3 is a main unit, and 4a to 4n are office lines.

A control circuit 30 is provided inside the main unit 3, and the terminals 1a to 1n, the DSS-equipped telephone 2, and the office lines 4a to 4n are provided via interface circuits 10a to 10n, 20, and 40a to 40n, respectively.
Is connected to

Further, the telephone 2 with the DSS function is provided with a called terminal (terminal
1a to 1n) function as a relay station when calling by relay, and have an outer shape as shown in FIG.

In FIG. 2, reference numeral 2A denotes a DSS console, which is composed of a function key 200 including an INT key for capturing an extension and a DSS key 201 provided for each of the terminals 1a to 1n.

On the other hand, 2B is an attendant telephone attached to the DSS console 2A, and an office line key 20 for capturing office lines 4a to 4n.
2. It has a keypad 203 for dial input and a handset 204 for telephone calls.

In the telephone with DSS function 2 having such a configuration, the office lines 4a to 4
When the intended called terminals 1a to 1n are called by relay in response to an incoming call from n, the DS corresponding to the called terminals 1a to 1n
By simply pressing the S key 201, the called terminals 1a to 1n can be called.

Separately from this method, the user picks up the handset 204, presses the INT key in the function key 200, captures the extension, and then dials the number corresponding to the called terminal 1a to 1n using the keypad 203. The called terminal 1a
11n can be similarly called.

FIG. 3 shows a dial number 3 in the telephone 2 with the DSS function.
This shows an example of a dial operation when calling the called terminals (1a to 1n) corresponding to the number 3.

The former of these paging modes corresponds to the DSS paging mode described in the section of the prior art, and the latter similarly corresponds to the dial paging mode.

The relay call control is performed by the control circuit 30 based on a signal corresponding to the operation content of the telephone 2 with the DSS function input through the interface circuit 20 in the main device 3 as described above.

In the conventional relay call control method, in any of the above-mentioned call modes, if the called terminals 1a to 1n perform transfer registration, the called terminals 1a to 1n from the relay console (telephone 2 with DSS function) are transferred. The call always arrived at the transfer destination terminal.

In this regard, in the relay call control system of the present invention, even if transfer registration has been made in any one of the above-mentioned call modes, the transfer registration is ignored and the call from the relay console is directly sent to the terminal of the transfer registration source. Things.

As an example, an example of operation control in a case where transfer registration is ignored in the dial call mode and a call from the attendant console is made to arrive at the transfer registration source terminal will be described in detail with reference to the flowchart of FIG.

When a terminal call request is generated in response to an incoming call from another terminal in the system (step 200), the telephone 2 with the DSS function (hereinafter, referred to as an attendant console) uses either the DSS call mode or the dial call mode described above. The called terminal (for example, 1a) is called in one calling mode (step 201).

At the time of this call control, the control circuit 30 determines whether or not the transfer registration has been made to the called terminal 1a (step 202). If the transfer registration has not been made, the call is directly received by the called terminal 1a. (Step 20
3).

On the other hand, if the transfer registration to, for example, the terminal 1n is made in the called terminal 1a, and the fact is determined in the judgment of step 202, the control circuit 30 sends the call to the called terminal 1a to the relay board (with the DSS function). It is determined whether or not the call is made from the telephone 2) (step 20).
Four).

In this determination, when it is determined that the calling terminal is a relay station, that is, when it is determined that the call is a relay call to the called terminal 1a, the control circuit 30 continues to receive the call based on the control content of step 201. Call terminal 1
It is determined whether the relay call for a is in the DSS call mode or the dial call mode (step 205).

When it is determined in this determination that the call is being made in the DSS call mode, the control circuit 30 causes the call to the called terminal 1a to arrive at the transfer destination terminal 1n according to the transfer registration contents ( Step 20
6).

On the other hand, if it is determined in step 205 that the call is being made in the dial call mode, the control circuit 30 ignores the transfer registration to the called terminal 1a and ignores the transfer registration. The incoming call is made to the called terminal 1a (step 203).

As a result, the paging terminals for each paging mode according to the presence / absence of transfer registration according to the relay paging control method of the present invention can be arranged as shown in FIG.

In the actual relay call control, the office lines 4a to 4n
The attendant console accompanying the incoming call from, for example, first performs a relay call of the called terminal in the DSS calling mode, and at this time, if the call is transferred to the transfer destination terminal, and the call cannot be realized due to the absence of the operator, Next, the processing corresponding to the above-mentioned steps 205 to 206 or steps 205 to 203 can be performed by calling the transfer registration source terminal via the dial call mode.

As described above, according to the relay call control method of the present invention, not only the transfer destination terminal but also the transfer registration source called terminal can be called according to the situation, even when the called terminal is performing transfer registration (fifth embodiment). It is possible to solve the problem that the telephone cannot be transferred because the transfer registration has not been canceled.

In the above embodiment, the processing method for ignoring the transfer registration when calling in the dial call mode for the called terminal in the procedure of the normal relay calling operation in the telephone 2 with the DSS function has been described. Conversely, the same effect can be obtained even if the transfer registration is ignored when calling in the DSS calling mode.

[Effects of the Invention] As described above, according to the call control method of the present invention, if the call is in the dial call mode, the called telephone terminal of the transfer source is called regardless of the transfer registration corresponding to the called telephone terminal. In this way, it is possible to call either the transfer destination telephone terminal or the transfer registration source telephone terminal depending on the situation, so that the transfer is performed even if the called party returns to the telephone terminal that is the transfer registration setting terminal. Even if you forget to cancel the registration setting, you can call the telephone terminal that is the transfer registration setting terminal, and it is possible to increase the possibility of making a telephone call with the called party Has excellent advantages.
