METHODS FOR TRANSMITTING A RECEIVED INFORMATION IN ABSENCE TO EXTERNAL TERMINAL IN A LINE TELEPHONE WHICH TRANSMITS AND RECEIVES A SHORT MESSAGE}

The present invention relates to a wired telephone terminal for transmitting and receiving text messages, and more particularly, to a method for transmitting received information received from a public telephone network to an external terminal in a wired telephone terminal in the absence of a user.

Recently, our country has implemented a Calling Identification Display (CID) service to prevent mischief calls, obscene calls and violent calls or to check incoming calls while users are away. The caller information service refers to a service that informs the caller of the caller's phone number and name before the call is answered by the display device of the communication terminal. Caller information services are currently provided in public switched telephone networks (PSTNs) as well as mobile networks.

As shown in FIG. 1, caller information provided by a public telephone network is called from a transmitting wired telephone terminal (hereinafter referred to as a transmitting terminal) 2 to a receiving wireline telephone terminal (hereinafter referred to as a receiving terminal) 4. When the connection is requested, the local exchange 6 provides the receiving terminal 4. The local exchange 6 transmits caller information to the receiving terminal 4 between the first incoming ring signal and the second incoming ring signal. This sender information is transmitted to the receiving terminal 4 in a frequency shift keying (FSK). When the receiving terminal 4 is busy, the local exchange 6 first applies a CPE (Customer Premise Equipment (CPE) Alerting) signal to the receiving terminal 4, and then receives the receiving terminal 4. After receiving an ACK (ACKnowledgement: ACK) signal from the sender information is transmitted. The wired telephone terminal, i.e., the receiving terminal 4, provided with the display portion then displays the caller information including the caller's name, telephone number, and telephone time.

Mobile communication networks provide caller information services to users in a similar way.

Caller information services that provide caller information to users in the above manner include caller information display services, call waiting caller information display services, caller information display prevention services, and anonymous call rejection services.

Caller ID service is a service that displays caller's phone number and caller's name in On Hook state and Off Hook state. Call waiting caller information service is a new call that calls a called party in off hook state. It is a service that displays caller information of and provides inter-call switching function using flash.

In addition, caller information display prevention service refers to a service that provides a function that the caller does not display his or her information to the called party on a call and line basis, and an anonymous call rejection service is provided to the called party. Refers to a service that provides the caller with the ability not to connect a call.

Meanwhile, the number of users who send and receive text messages using a mobile communication terminal is increasing. Text messaging has gained considerable popularity, especially among students, because text messaging costs are much lower than voice calls.

Recently, however, wired telephone terminals capable of sending and receiving text messages have appeared. A wired telephone terminal capable of transmitting and receiving text messages is connected to a PSMSC (PSTN Short Message Service Center) connected to a local exchange of a public telephone network to transmit and receive a text message with another wired telephone terminal. PSMSC and wireline telephone terminals send and receive text messages in a frequency shifted manner.
