Abstract

PURPOSE: A method and a system for notifying of a calling number on an incomplete call are provided to extract a caller's telephone number if a call is not able to be received by a receiver's terminal, and to temporarily store the extracted number, then to deliver a short message to the receiver's terminal to inform of the call, so that the receiver can receive calling information on an incomplete call in real time. CONSTITUTION: If a receiver's terminal is powered off or the receiver is absent, a receiving incomplete call is generated(S100). An SSP(Service Switching Point) decides whether the receiver is registered in an incomplete call notify service(S110). If so, the SSP triggers a CID(Caller Identification) to an SCP(Service Control Point) through a common network to temporarily store the CID(S130). The SCP confirms whether the receiver is a normal subscriber(S140). If so, the SCP transmits the stored CID to an SMSC(Short Message Service Center) of a mobile communication network(S160). The SMSC delivers the CID to the receiver's terminal in short message type, so that the terminal can display the CID on a screen as a short message(S170).

Convert to form The SMSC 64 finds the phone number of the mobile communication terminal 70 to which the short message containing the CID of the incomplete calling terminal 20 is transmitted, and transmits the phone number to the MSC 66 having the corresponding station number. The MSC 66 transmits the short message to the corresponding mobile communication terminal 70 according to the telephone number attached to the short message. Therefore, the short message containing the CID of the incomplete calling terminal 20 is the mobile communication terminal of the incomplete landline telephone 25 user who has received the incomplete call through the base station controller 68 and the base station 69 that manage the area. Delivered to 70.

3 is a flowchart illustrating a method of reporting an incomplete call origination number according to the present invention, which will be described in detail with reference to FIGS. 1 and 2.

First, the calling terminal 20 makes a call request to the landline telephone 25 to the wired communication network (30). At this time, the incoming call completes on the incoming landline when the power of the incoming landline telephone 25 is off or missed calls. (S100) Here, the calling request signal is the calling party's calling number and calling attempt time. Caller information. Then, the incomplete call of the incoming wired telephone 25 for the transmission attempt of the calling terminal 20 is detected by the SSP 41 connected to the wired communication network 30. In addition, it is determined whether the incoming landline telephone 25 incomplete call is a phone subscribed to the intelligent network service. That is, the wired caller in the SSP 41 determines whether the subscriber of the incomplete call notification service (S110). If the wired caller is not a subscriber of the incomplete call notification service, the call is terminated (S120).

At this time, if the landline called party is a subscriber of the incomplete call notification service and the called landline telephone 25 is a phone subscribed to the intelligent network service, the SSP 41 uses the CID of the incomplete call originating terminal 20 as a common network ( 42) to trigger the SCP (43) to be temporarily stored (S130). Subsequently, SCP 43 of the intelligent network 40 checks with the HLR 62 of the mobile communication company to which the landline called party subscribes (S140). At this time, the SCP 43 of the intelligent network 40 registers in advance the mobile communication company and mobile phone number to which the landline called party subscribes. If the landline party is not a normal subscriber of the mobile communication, the call is terminated (S150).

At this time, if the wired called party is a normal subscriber of the mobile communication, SCP 43 transmits the CID of the temporarily stored incomplete call originating terminal 20 to the SMSC 64 of the mobile communication network 60 (S160). The SMSC 64 transmits the CID of the incomplete call originating terminal 20 received from the SCP 43 to the mobile communication terminal 70 of the incomplete call telephone user in the form of a short message, and sends the mobile communication terminal ( 70, the CID of the incomplete caller is displayed as the short message (S170). The user of the mobile communication terminal 70 can call the incomplete caller by checking the displayed caller's CID and pressing the call button.
