METHOD FOR INFORMING OF RECEIVER'S PAGING CONDITION TO CALLER

摘要

A method for notifying a sender of the fact that a receiver is being called is provided to be capable of delivering another ring back tone for notifying that a receiver is being called, when a receiving terminal substantially calls the receiver, thus a sender can know a time when the receiver is called. A ring back tone is delivered to a sending terminal(100) according to call processing for the sending terminal(100) which demands a call connection(S100-S125). An AWI(Alert With Information) message is transmitted to a receiver terminal(300) according to call processing for the receiving terminal(300)(S130-S160). If an ACK(Acknowledgement) signal to the AWI message is received from the receiving terminal(300), another ring back tone which notifies that a receiver is called is delivered to the sending terminal(100) instead of the first ring back tone(S165-S175).
