Description

Call waiting service device for telephones

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a call waiting service device of a telephone, and more particularly, when a subscriber registered in a call waiting service receives a call from any subscriber during a telephone call with a specific subscriber. The present invention relates to a device for displaying a display.

When a subscriber registered in the conventional call waiting service receives a call from any subscriber while making a phone call with a specific subscriber, the exchange provides call waiting service to the subscriber registered in the call waiting service. That is, a subscriber registered in a call waiting service can selectively make a phone call with two subscribers who want to connect a call to him or her and wait for the remaining call.

However, in such a conventional technology, when a subscriber registered to a call waiting service receives a call from any subscriber while making a phone call with a specific subscriber, the subscriber's telephone number is not known. Sometimes it is not easy to determine whether to switch. In particular, if you can see that a more important call has been made during the current important phone call will be switched immediately, but if you receive a non-critical call, you do not need to receive the call immediately waiting for the incoming call. You can also refuse calls for calls you do not want to receive.

The present invention has been made to solve the above-mentioned shortcomings, and when a subscriber registered in a call waiting service receives a call from any subscriber while making a phone call with a specific subscriber, the telephone number of the subscriber waiting for call waiting service is registered. Call waiting service registration is provided on a display unit separately installed on the telephone used by the user to provide a call waiting service device of the telephone to allow the subscriber to view the displayed telephone number to maintain the current call or to transfer a call with any subscriber. There is a purpose.

In order to achieve the above object, the present invention provides a call waiting service apparatus for a telephone, comprising: a transceiver for providing a function of transmitting and receiving with an external telephone station; A user registered in a call waiting service receives and decodes a text signal according to the arbitrary subscriber provided from the telephone company on the basis of a call coming from any subscriber while talking to a specific subscriber through the transceiver. Micom; A handset for allowing the user to make a phone call with the other party through the transceiver; A key input unit for providing a specific key signal to the telephone station through the microcomputer and the transceiver to select whether to transfer the call to any subscriber; A text signal generator that generates a text signal to actually display the corresponding text based on the text signal decoded from the microcomputer; And a display unit for receiving the text signal from the text signal generator and displaying the text according to the text signal generator to allow the user to view the arbitrary subscriber information.

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

1 is a block diagram showing an embodiment of a call waiting service device of a telephone according to the present invention, including a transceiver 2, a ring signal detector 4, a microcomputer 6, a telephone ring output unit 8, and a handset unit ( 10), a key input unit 12, a character signal generation unit 14, and a display unit 16.

In the same figure, the ring signal detector 4 detects the ring signal provided from the telephone station via the transceiver 2 and provides it to the microcomputer 6. At this time, the ring signal is provided when a call is made to the user as is well known. In addition, the user referred to in the present invention is a user registered in the call waiting service.

When the microcomputer 6 receives the ring signal from the ring signal detector 4, the microcomputer 6 drives the telephone ring output unit 8 so that the telephone ring output unit 8 rings the telephone ring. In addition, the microcomputer 6 receives and decodes a text signal according to an arbitrary subscriber provided from a telephone station based on a case where a call is received from an arbitrary subscriber while the user is talking to a specific subscriber through the transceiver 2. The text signal generator 14 is provided.

The handset 10 allows the user to make a phone call with the other party through the transceiver 2.

The key input unit 12 selects whether to transfer a call to any subscriber by providing a specific key signal to the telephone station through the microcomputer 6 and the transceiver 2 by the user's key operation.

The text signal generation unit 14 generates a text signal for displaying the actual character based on the text signal decoded from the microcomputer 6 and provides the text signal to the display unit 16 so that the user can select any subscriber telephone through the display unit 16. Allows you to view information such as numbers. In this case, the display unit 16 may be configured as a display device such as a liquid crystal display (LCD).

FIG. 2 is a flowchart illustrating an exemplary operation of the call waiting service apparatus of the telephone according to FIG. 1.

First, the telephone station checks whether the user is talking to a specific subscriber (step 22).

In step 22, if the user is talking to a specific subscriber, it is checked whether the user is a call waiting service registered subscriber (step 24).

In step 24, if the user is a call waiting service registered subscriber, it is checked whether a call is received from any subscriber (step 26).

When a call is received from any subscriber in the step 26, a call waiting sound is transmitted to the user and transmitted to the display unit 16 through the transmission / reception unit 2, the microcomputer 6, and the text signal generation unit 14. Information such as subscriber's telephone number is displayed for the user to view (step 28).

It is checked whether the user selects any subscriber through the key input unit 12 (step 30).

When the user selects any subscriber through the key input unit 12 in step 30, a call waiting service is provided to connect the user call with any subscriber call (step 32).

On the other hand, in step 30, if the user does not select any subscriber through the key input unit 12, a busy tone is transmitted to any subscriber (step 34).

As such, in order for the apparatus according to the present invention to operate correctly, it is necessary to provide a service at the telephone station.

As described above, in the present invention, when a subscriber registered in call waiting service receives a call from any subscriber while making a phone call with a specific subscriber, the subscriber uses the telephone number of the subscriber in call waiting service registration. It is displayed on the display unit 16 separately installed so that the call waiting service registered subscriber can view the displayed telephone number and maintain the current call or switch the call with any subscriber. Therefore, the user can easily select and receive a call.
