METHOD FOR SUPPLYING ABSENT RESERVATION CALL SERVICE, PERIODIC RESERVATION CALL SERVICE, AND RECEIVER RESERVATION CALL SERVICE TO MOBILE COMMUNICATION TERMINAL AND SYSTEM THEREFOR

摘要

PURPOSE: A system for supplying a reservation call service to a mobile communication terminal is provided to supply a preset short message or an announcement if a call is made while a receiving terminal is set in absent mode, and to supply an absent reservation call service, a periodic reservation call service, and a receiver reservation call service, so that a receiver can confirm an absent reservation call and attempt a call connection. CONSTITUTION: A mobile communication terminal(210) is registered in a reservation call service for receiving a callback number message which informs of a reserved call at preset time. An MSC(240) transmits the callback number message to the mobile communication terminal(210) through an RAN(230). A reservation call service server(320) supplies the reservation call service for processing the registration of the reservation call service, managing subscribers, and directing the callback number message to be prepared and transmitted every preset time. A subscriber DB(330) adds, changes, and deletes subscriber information to store the subscriber information. An SMS server(270) receives a direction to prepare and transmit the callback number message, and prepares/transmits the callback number message to a target terminal(220).
