A control method and a computer-readable recording medium having recorded thereon a program for realizing the method.

As telephones become popular, they are used in various environments. However, the etiquette of the telephone tends to become more numb as compared to the rapid popularity of the telephone. In other words, any call, including bad calls such as prank calls, indecent calls, temptation calls, and intimidating calls, gives the called party severe mental pressure, stress, anxiety, etc., which is a major social problem. Moreover, such random call may cause severe pain to the called party.

Therefore, until now, various measures have been taken to prevent an arbitrary call. In terms of personal convenience and privacy protection, a caller ID (CID) service is currently implemented to inform the caller's telephone number in advance. Leave the other's information to get rid of frustration. This service frees you from phone stress caused by incoming calls, and prevents you from reading the phone number displayed on your device and avoiding it if you don't know or bother yourself.

By the way, CID service that is currently in service collects the calling number from the calling exchange through the inter-station signaling method for the incoming call and transmits the calling number through the subscriber line before answering the subscriber. If the display device of the terminal is displayed and the additional name service function of the source name is required, the data is requested and received from the business name display server to obtain the name data of the calling number collected by the destination exchange. The business name is transmitted to the display device of the called party's wired / wireless terminal through the subscriber line.

As such, recently, a CID service for displaying a calling party's telephone number on a called terminal in a telephone network has been provided, and information such as calling time, calling subscriber number, caller's name, etc. is received from a called exchange CID service device of a telephone network to a called terminal. A signal transmission interface for transmitting and displaying to the CID service device on the side is defined.

However, in the existing telephone network, a signal transmission method from an exchange side to a subscriber side is not possible through an analog telephone line, and thus services corresponding to multiple subscriber number services of an integrated service digital network (ISDN) are not provided. However, in the environment where multiple telephone lines are used by multiple users, a service is provided by a method of transmitting a different ring signal from an exchange for each subscriber number in consideration of demand for selective reception, but with a problem that a user must identify a ring signal. There is a problem in that a device such as a facsimile (FAX) or an answering machine that automatically responds to the ring signal cannot identify and operate the ring signal. In addition, in the case of receiving a CID service using a single phone number in a general home, caller information is displayed for incoming calls to all family members, and privacy between family members cannot be guaranteed, which is an obstacle to the distribution of CID services.

The present invention has been proposed to meet the above requirements, and provides a ringing ring signal to only a terminal corresponding to a specific subscriber number among a plurality of terminals connected to an analog subscriber line, thereby implementing a multiple subscriber number service. It is an object of the present invention to provide a subscriber end device, a method of controlling a reception thereof, and a computer-readable recording medium that records a program for realizing the method.
