Description

Voice service-enabled calling information display phone {The telephone for displaying and notifying caller ID with sound}

The present invention relates to a caller information display phone that displays caller information. In particular, a simple caller's telephone number or name can be searched for a database, as well as a predetermined caller's information. The present invention relates to a voice service capable call information display telephone.

The caller information display service was limitedly used by Korea Telecom only when there was a specific reason such as obscene or intimidating call. However, recently, all information is transferred to the telephone company, and the service is expanded so that anyone can apply for the service by simply signing up for the telephone company. I can do it.

The caller ID (hereinafter referred to as CID) may be a caller's phone number or a call date and time such as a reception time and date. Here, CID is used as a caller's phone number.

Fig. 1 is a block diagram showing a connection relationship between a calling information display telephone and a telephone station. The calling party information display service is shared between the calling station 11 and the called station 13 by the telephone subscriber-specific CID database 12. When the caller makes a call to the calling party's telephone 10, the receiving party's telephone 14 receives a signal including CID information from the called station 13 via the calling station 11.

The calling telephone 10 may be a cellular phone or a public telephone.

At this time, the CID is displayed only when the called party's phone 14 is a phone capable of displaying the calling information.

Therefore, the user must check the LCD screen with the eyes to know the caller, if there is a problem that is missed, even if the call is important even if not confirmed.

On the other hand, when forming complex relationships in social life, people come into contact with various people. Unless intimate relationships are formed, they often do not talk on the phone frequently and cannot remember what the caller is with the user. have.

Therefore, in addition to the caller's phone number, more specific information, for example, the name of the company or office as well as the caller's name, occupation, etc., must be displayed to select and call the caller.

However, the conventional dialing information display telephone cannot display such information, and thus, the telephone user has a problem that he misses it by mistake even though the telephone is sent to an important caller.

The present invention has been made to solve the above-mentioned problems, the object of the present invention is to display the caller information on the LCD screen and the voice at the same time, so that you do not have to directly check the LCD screen The present invention provides a voice service capable call information display telephone capable of accurately identifying a caller by making a database and searching specific information of a caller.
