Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an improvement in the incoming call display method of a telephone with a display function connected to an exchange in a telephone exchange system.

[Technical background of the invention]

In recent years, telephones have been equipped with a display using a liquid crystal display (LCD) or a light emitting diode (LED), etc., and this display displays the telephone number of the incoming call, the telephone number of the calling party, the duration of the call, etc. A telephone switching system has been developed that displays the following:

The incoming call display on telephones with display functions in such conventional telephone switching systems is such that when a certain terminal is idle, the information of the calling party who made the first incoming call to that terminal is displayed first; If there is an incoming call from Kazuya, subsequent incoming calls will be in a display waiting state. Then, when the call for the first incoming call ends and the line is disconnected, and the other incoming calls continue, information about the calling party who made the other incoming calls for the first time will be displayed on the telephone display. It will be displayed.

[Problems with background technology]

However, such a conventional incoming call display method has the following problems.

(1) While making a call using the line corresponding to one phone number on a telephone with display function;
1 when an incoming call occurs to that phone number.
6. Yo (Yo, □9o. Yo 84. When there is an incoming call to □, the recipient can only see the information about the calling party that corresponds to the first incoming call.

(2) If multiple phone numbers are assigned to a single display phone and there are incoming calls to multiple phone numbers at the same time, the recipient must first receive the incoming call. In addition, it is not possible to determine which number among the plurality of telephone numbers assigned to this telephone the calling party is making an incoming call to.

[Purpose of the invention]

The present invention makes it possible to identify multiple calling parties when multiple incoming calls occur to a telephone with a display function, and furthermore, when multiple telephone numbers are assigned to this telephone, which telephone number is assigned to the telephone? An object of the present invention is to provide an incoming call display method for a telephone with a display function that allows confirmation of whether an incoming call has been made. ) [Summary of the Invention] The present invention provides a telephone exchange with a first storage means for storing information of a plurality of calling parties corresponding to a plurality of incoming calls that can be answered by a telephone with a display function. When a read operation is performed from the telephone, information on a plurality of calling parties stored in the first storage means is selectively displayed on the display of the telephone. Further, the present invention provides, when a plurality of telephone numbers are assigned to a telephone with a display function, a second storage means for storing the telephone number from which an incoming call was made, provided in the exchange together with the first storage means, The information of the calling party stored in the first storage means and the corresponding telephone number stored in the second storage means are selectively displayed by a read operation from a telephone with a display function. It is something.

[Embodiments of the invention]

FIG. 1 is a circuit block diagram of a telephone exchange system to which an incoming call display system is applied according to an embodiment of the present invention. E is an electronic exchange, which operates under the control of a central controller (CC) 1. FIG. A switch circuit (SW) 2 and a telephone T with a display function each serving as a terminal.

~Ill, are connected to line circuits Lc, , -Lc, trunk circuits TRK and TRK2 connected to office lines C101 and C102, respectively, transmission registers OR and OR, and tone ringer circuit (TR )
3, and a memory 4 that stores operating programs for the central controller 1, various control data, and the like.

In the memory 4, there is a memo 1JllviR1 that is not registered at the called party's end.
and an incoming telephone number registration memo 1JeviR2 are provided. In addition, telephones with display function T0 to T, G, handset 5 and normal push-button type dial keys 6
In addition to this, an extension key 7 to which an extension number has been assigned and a light indicating that the extension number assigned to that extension key 7 is calling or answering.

An indicator lamp 8 and a memory M which display by blinking, etc.
A display 9 for displaying the registered contents of and M is provided.

In this case, telephones T0 and T have four extension numbers "11", "12", "13" and "t4", respectively.
However, on telephone T2, (3 extension number ru).

It is assumed that two extension numbers ``12'' and ``13'' are assigned to telephone T, ``13'' and ``[4''. Also, the number of one station line C101 is r042, for example.
5-83-1111J.

Figure 2 (al) and (b) show the unregistered memory M of the called party's end.
1 shows a memory map of R,1 and incoming telephone number registration memory M2, each of which is provided corresponding to a terminal. 0FF
Data H indicates the initial state of the memory.

In the memory map of FIG. 2, since telephone T2 pressed its extension key "11" and dialed "13",
A state is shown in which there is an incoming call to the extension number "13" of each telephone, and an incoming call from the station aC101 to the extension number "12" of each telephone.

If the phone T. -T, is a telephone to which multiple telephone numbers are not assigned, it goes without saying that the incoming telephone number registration memo IJ M R2 is not required, but in this implementation, each telephone number T0 to T3 is A case will be explained in which multiple telephone numbers are assigned.

If there is an incoming call from the central office line C10l or ClO2, the central control unit 1 will proceed to the flowchart M--1 in FIG.
- Execute control using the procedure shown in .

That is, when there is an incoming call, the central control unit 1 first determines whether or not there is a call via the central office line C101 or ClO2 (step 1o1). If there is no call, this determination is repeated; if there is a call, Keys that can respond are determined according to a predetermined priority order (step 102). The priority order mentioned here is, for example, for the office line C101, "1
1” → “12” → “13” → “14”,
Regarding the central line ClO2, "14" → "13" → "12"
” → “11”. Next, it is determined whether there is a key that can respond (step 103), and if there is no key that can respond, a busy process is performed (step 104), and the process ends. If there is a responsive key, the telephone T has the responsive key (r12j in this case). -Tt, a calling operation (blinking of the lamp of key "12") is performed (step 105).

If this incoming call is via the central office line C101, the other party's unregistered memo IJMRI telephone T in FIG. 2(a).

-Telephone T that stores "C101" in the storage location corresponding to T2 and has incoming telephone number registration memo IJMR2 in FIG. 2(b). - Store "121" in the storage location corresponding to T2 (step 106). Next, it is determined whether there is a response or not (step 107). If there is no response, the determination is repeated, and if there is a response, there is no response. The lamp of the key "12" is turned on (step 108), the "C101" and "12" stored in the memos IJMRI and M-box 2 are cleared, respectively (step 1o9), and the process ends.

Next, control in the case of a call will be explained according to the flowchart shown in FIG. First, the phone T2 has the key "
11" is pressed and "13" is dialed, the central controller 1 determines whether there is an extension call or not. Step 3
01), then check whether it is busy or not in step 3.
02), if it is busy, a busy process is performed (step 303), and the process ends. If it is not busy, a ringing action (key "
13" lamp blinking) (step 304), and then press the key number "11" and the calling extension number "11" (step 304).
13'' are stored in the memories M1 and MB2, respectively (step 305). Next, it is determined whether there is a response or not (step 306), and if there is no response, this determination is repeated,
If there is a response, the lamp of the key "13" is lit (step 307), the numbers "11" and "13" stored in the memories MRI and M-box 2 are cleared (step 308), and the process ends.

Further, when making a call to an outside line from the telephone T0, for example, if the key "11" is pressed and the "pregnancy" key of the dial key 6 is pressed, the process proceeds from step 301 to step 30.
2, an idle line C101 or ClO2 is detected. Next, step 311 determines whether there is a vacant office line.
), if there is a vacant office line, it is connected to the vacant office line (step 312), and central office line origination processing is performed.

The above is the central line, /Q 1. ,, This is the processing flow when there is an incoming call or an outgoing call from the C102, and the memory M shown in FIGS.
几1゜As per the memory contents of MB2, the extension number is "11" at the beginning.
When a call is received from C101 to extension number "13" and then from extension number "12" from central office line C101, the numbers are displayed as follows.

For example, when there is a key operation (for example, pressing the key "#") to request display switching from the display function telephone T, the central control device 1 executes control as follows. FIG. 5 is a flowchart showing the control procedure.

That is, when a display request occurs, the central control device 1
First, it is determined whether or not this readout is the first readout (step 201). If it is the first readout, the readout counter is set to "O".
” (step 202), otherwise the counter is incremented by one (step 203).

Next, the other party's terminal storage memory is read out according to the read counter, and it is determined whether there is data to be displayed (step 204). If there is data to be displayed, the other party's terminal is read out from the other party's unregistered memo IJMRI according to the reading counter and displayed (step 205). Next, read out the incoming phone number and display it from the incoming phone number registration memo IJMR2 according to the counter.
Step 206). In this example, 1'
On the display 9 of telephone T, the first operation of the key "#" will display "11→13", and the second operation of the key "#" will display "0425-83-1111→12". will be displayed. Even if the key "#" is operated roughly, no data is displayed because there is no data to be displayed in the memory MRI. When the display process is completed in this manner, the process returns to the main flow (not shown) for executing various exchange processes.

Furthermore, when a telephone number assigned to all telephones connected to a telephone exchange is used to make or receive a call, when an incoming call is made from a central office line, information regarding that central office line is stored, Needless to say, a similar incoming call display can be performed.

〔Effect of the invention〕

As is clear from the above explanation, when there are multiple incoming calls on a telephone with a display function, all the information about the calling party can be checked by operating the telephone, so it is possible to check the information of the calling party who should answer. This has the advantage of allowing the user to use the switching system more smoothly since it is possible to select the response order and also to know whether there are incoming calls to multiple telephone numbers or telephone numbers.
