Abstract

PURPOSE:To reduce a trouble of a called party by registering an important talking party in advance and displaying the recognition of the party when the call comes from the party. CONSTITUTION:The user uses an input processing section 15 to register and store opposite party information such as plural caller numbers having the possibility of an incoming call in advance to an opposite party caller number management section 17 and enters a numeral or the like representing the rank of importance. When an incoming call is received during talking through a B1 channel, a call control processing section 14 extracts a caller number from the call setting information and sends the number to an opposite party caller number comparison section 16, the comparison section 16 compares and collates the opposite party caller number with the registered content of the management section 17 and displays the state of the display section 19 while revising it in response to the importance of the caller. Thus, the user replies an important party immediately without a trouble of consideration of the importance of the caller sequentially.

Problem to be Solved by the Invention By the way, when there is an incoming call during a call, the user (called party) either temporarily interrupts the call and answers the incoming call, or continues the call without answering the incoming call. You have to decide whether to do so. This judgment is ultimately made by the called party himself, taking into consideration the importance of the other party and the content of the call, and the importance of the other party identified from the calling party number displayed on the display. However, since there are a wide variety of people making calls, including people who want to discuss important matters such as business negotiations, simple friends, and immediate family members, it is difficult to tell who the caller is from the number displayed on the display. It is extremely troublesome to determine whether the caller is a high-priority person or not for each incoming call.

In view of these points, the present invention registers in advance the other party of high importance, and displays it in a recognizable state when there is an incoming call from that party, thereby saving the called party the trouble of making decisions. The aim is to reduce the

Means for Solving the Problems In order to achieve the above object, the present invention provides an ISDN telephone device that is connected to an ISDN digital communication network and is capable of receiving incoming call notification service during communication. a registration means for registering a number in advance; a comparison means for comparing the calling number of the incoming call with the calling number registered in the registration means when there is a communication call during communication; and a comparing means for comparing the calling number of the incoming call with the calling number registered in the registration means; It is characterized by comprising a display means for changing the display state according to the degree of importance, a channel switching means for selectively switching between two communication channels, and an operation means for switching the switching means.

Effect According to the above configuration, when a user is talking on one channel and there is an incoming call on the other channel, the calling number of the other party of the incoming call is extracted and the calling number is registered in the registration means. compare. The comparison result determines the importance of the caller, and the display status is changed accordingly, allowing the user to recognize the importance of the incoming call and, depending on this, either continue the current call or operate the operating means. You can also switch channels and talk to the caller who received the incoming call.

Embodiment FIG. 1 shows a block diagram of an ISDN telephone device in an embodiment of the present invention. In FIG. 1, 10 is a system control unit that controls the entire system, 11 is a communication control unit that controls a call control interface with the ISDN digital communication network, and 12 is a communication control unit that controls a call control interface with the ISDN digital communication network.
13 is a voice call processing unit including a handset; 14 is a call control processing unit that controls two calls; 15 is a call control processing unit that controls call control messages of the communication control unit; An input processing unit 16, which is operated when switching a call channel, extracts the calling party number information from the call control processing unit when an incoming call is received, compares it with the calling party number information in the calling party calling number management unit, detects a match, and when a match is found, displays the information on the display unit. a calling party number comparison unit which instructs to display the other party's calling number;
Reference numeral 7 denotes a destination calling number management unit that stores and manages a plurality of destination caller information input and set in advance by the user; 18 a switching control unit that switches between two channels whose connection is controlled via a communication control unit; 19 is a display section. This display section 19 is not limited to visual display, but also auditory display (
For example, it may be a buzzer, a voice sounding device, etc.). This display section 19 can be switched to at least two different display states. The first display state operates when the caller number is registered in the management unit 17,
The second display state operates when the caller number is not registered in the management unit 17. In the first display state, for example, the caller number is displayed on the LCD display screen, and a sounding body is driven so that the called party can hear the caller's number. On the other hand, the second display state is simply displayed on an LCD display screen, for example.

The operation of the ISDN telephone with the above configuration will be explained below. First, the user registers and stores in advance, through the input processing section 15, other party's caller information such as a plurality of caller numbers that may receive a call in the other party's calling number management section 17. FIG. 2 shows information stored in the management section 17.

As other information, for example, a numerical value indicating a rank of importance, etc. can be input.

Next, when the user receives an incoming call from the ISDN digital communication network 20 while using one channel of the digital communication network, the system operates according to the sequence shown in FIG. That is, when an incoming call is received during a call using the B1 channel, the call control message processing unit 12 receives call setting information and sends it to the call control processing unit 14, and also sends the calling information to the digital communication network 20. Send it back. The call control processing unit extracts the caller number from the call setting information and sends it to the other party's caller number comparison unit 16. The comparison unit 16 compares and checks the other party's calling number with the registered contents of the management unit 17, and if there is a matching calling number, the display unit 19 is set to the first display state, and if there is no matching number, the display unit 19 is set to the first display state. Change the display state to 2 and display.

When the display section 19 operates in the first display state, the called party recognizes the importance of the incoming call, and if the importance of the current call content is low, the called party operates the input processing section 15 to change the incoming call through the switching control section 18. Switch the call channel. by this,
Response information is sent to the digital communication network 20,
Response confirmation information is returned from the digital communication network 20, and a call can be made on the B2 channel.

FIG. 4 is a flowchart showing the above operation.

This flowchart is called every time there is an incoming call.

#1 is a step to determine whether the ISDN telephone device is in a call, and if it is not in a call, proceed to #2.
Perform normal response processing. If the call is in progress, proceed to #3 and extract the caller's calling number from the call setting information. This process is performed by the call control processing section 14. #4 and #5 are processes performed by the other party's calling number comparison unit 16, and #6 and #7 are operations performed by the display unit. Since these operations have already been explained, their explanation will be omitted. #8 is a step in which the user operates the input processing unit 15 to determine whether or not the channel has been switched, and the current call is continued until the channel switching operation is performed (#9). , when the channel is switched, the process proceeds to #lo to perform response processing and start a call on the new channel.

Incidentally, in the above embodiment, the destination calling number management section 17 stores a plurality of calling party numbers with the same importance, but the other information column in FIG. 2 can be used to give different weights. It can also be memorized. In that case, the number of the other party who is currently on the phone is also given importance weight, and this weight is compared with the weight of the caller who received the incoming call, and the relative number of the other party of the incoming call with respect to the number of the other party who is currently on the phone is determined. It is even more convenient to display the degree of importance.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, when there is an incoming call during a call, the display state is changed depending on the importance of the caller of the incoming call, so the user can make the call one by one. It is possible to immediately respond to an important person without the trouble of considering the importance of the other person, which has a great practical effect.
