Abstract: PURPOSE: A method for supplying a calling number identification presentation(CNIP) service using mobile terminal rings is provided to change the mobile terminal rings according to originators, so as to make a receiver identify the originators and to designate which terminal ring is generated when a call is made from an originator, and so as to designate which terminal ring is generated when other user picks up a self telephone. CONSTITUTION: If an originator transmits a call(202), an originating mobile switching center(MSC) transmits a location request invoke(LOCREQ) message to a home location register(HLR)(203), to request a subscriber location. If the HLR transmits a routing request invoke(ROUTREQ) message to a visitor location register(VLR) of the originating MSC(204) to request connection information, a terminating MSC returns a temporary local directory number(TLDN) to the HLR through a routing request return result(routreq)(205). The HLR returns the TLDN to the originating MSC through a location request return result(locreq)(206). If the originating MSC attempts a call connection to the terminating MSC(207), the terminating MSC informs a terminal of an incoming call. The terminating MSC transmits calling number identification presentation(CNIP) information to the terminal(208). The terminal having a telephone directory made out by a user retrieves whether an originating telephone number exists in the telephone directory(209). If so, a name of the retrieved originating telephone number is displayed on a screen(210). The terminal retrieves an originating telephone number table to check whether items corresponding to the received originating telephone number exist(211). If so, a corresponding terminal ring is read from a memory(212). If the items do not exist, a basic terminal ring is read from the memory(213). The read terminal ring is outputted through a speaker(214). The terminal continuously performs call processes(215). If a receiver responds to the call processes, a call is connected(216).
