Title: Method of informing a sender the end of a call in a mobile communicator system
Inventor: KIM JU MYEONG
IPC: H04B7/26
Filed: 2002-07-25
Abstract: PURPOSE: A method for informing call end in a mobile communication terminal system is provided to sense a call end state of a termination terminal and notify the call end state to a caller when a caller fails in call connection with a callee by a busy state of the callee. CONSTITUTION: A switch confirms a busy state of a termination terminal according to the origination request of an origination terminal(S20). If the termination terminal is not in the busy state, the switch connects a call between the origination terminal and the termination terminal(S30). If the termination terminal is in the busy state, the switch transmits a busy guidance broadcasting to the origination terminal(S40). The switch transmits a selection guidance broadcasting of a call end informing service, a line occupation service and a termination-side message transmission service, and waits for the service selection of a caller(S50). If the switch senses the call end state of the termination terminal after the caller selects the call end informing service and notifies the call end state to an SMSC(Short Message Service Center), the SMSC transmits a short message to the origination terminal and connects the call between the origination terminal and the termination terminal(S60). If the switch senses the call end state of the termination terminal after the caller selects the line occupation service, requests the call to the termination terminal, occupies a line, and notifies the fact to the SMSC, the SMSC transmits a short message to the origination terminal and connects the call between the origination terminal and termination terminal(S70). If the caller selects the termination-side message transmission service and the switch the fact to the SMSC, the SMSC transmits a short message to the origination terminal for informing the call end of the termination terminal and transmits a number of the origination terminal and a short message in which the caller wants to talk with a callee to the termination terminal(S80).
