Abstract

The present invention relates to a method and apparatus for providing a calling number of an incomplete call, and in more detail, a method and apparatus for providing a calling number of an incomplete call for a receiving terminal when the incomplete call, which cannot receive a call, occurs. A calling number providing system provides the calling number of an incomplete call, wherein the system comprises a TCAP connector, a TCAP message receiver, a TCAP message analyzing unit, an incomplete call logging unit, a message informing unit, a controller, a message searching unit, a short message creator, a database broker, and SMCI/SMPP message constructing unit, a short message dispatching unit, and an SMCI/SMPP connector.

TCAP message analyzing unit for analyzing the incomplete call received by the TCAP message receiver;

message informing unit for transmitting incomplete call information, which is transmitted from an incoming MSC, to a controller;

message creator for creating a message comprising the calling information, which is extracted from the incomplete call information, and transmitting the message to the controller;

the controller for controlling the operation of the message creator and transmitting the message to a SMCI/SMPP message constructing unit;

message searching unit for searching data such as caller'"'"'s subscriber information of the incomplete call, when the message searching unit receives receivable state information of an incoming terminal;

the SMCI/SMPP message constructing unit for converting the format of the message into SMCI/SMPP format;

message dispatching unit for transmitting the message, which is transmitted from the SMCI/SMPP message constructing unit, to an SMCI/SMPP connector;

the SMCI/SMPP connector for connecting the calling information providing system with the message service center; and

short massage service center(SMSC) for receiving the message from the calling information providing system and for transmitting the message to the incoming terminal via incoming MSC.

2. The system of claim 1, wherein the incomplete call information providing apparatus is HLR(Home Location Register) or MSC(Mobile Switching Center).

3. The system of claim 1, wherein the calling information providing system comprises a database server, which stores the incomplete call information received from the incoming MSC, and a database broker, which connects the database server with the calling information providing system.

4. The system of claim 3, wherein the calling information providing system further comprises an incomplete call logging unit, which creates incomplete logging time and sets up the incomplete logging time by time information for telephone call and stores the analyzed incomplete call information on the database server through the database broker, and a message searching unit, which searches the incomplete call information corresponding to the incoming terminal after the incoming terminal has become ready for receiving.

5. The system of claim 3, wherein the calling information providing system further comprises a message dispatch logging unit for storing the message transmission particulars of the message dispatch logging unit on the database server through the database broker.

6. The system of claim 3, wherein the calling information providing system further comprises an IVR server, which comprises a searching unit of incomplete call information for searching incomplete call information stored on the database server, a TTS engine for converting searched incomplete call information into a voice signal, and a callback unit for connecting a call by a caller terminal corresponding to the caller information comprised in the incomplete call information.

7. The system of claim 3, wherein the calling information providing system further comprises a WAP server, which is a searching unit of incomplete call information for searching incomplete call information stored on the database server, and a callback unit for connecting a call by a caller terminal corresponding to the caller information comprised in the incomplete call information.

8. The system of claim 1, wherein the calling information providing system further comprises an advertisement creator for creating an advertisement phrase.

9. The system of claim 1, wherein the calling information providing system is equipped within a VMS apparatus or an RCS apparatus.

10. The system of claim 1, wherein the incomplete call information is classified into recognizable incomplete call information and unrecognizable incomplete call information, and comprises identification information for identifying the incomplete call information.

11. The system of claim 1, wherein the message includes at least caller'"'"'s number selected from caller'"'"'s number, incoming subscriber'"'"'s number, caller'"'"'s location information, advertisement phrase, and call time.

12. A method for providing a calling information (providing) of an incomplete call, comprising the steps of:

(a) receiving a call connection request comprising a caller'"'"'s number and an incoming subscriber'"'"'s number from a calling terminal;

(b) requesting location information corresponding to an incoming terminal from a HLR(home location register);

(c) extracting location information and incomplete call information of the incoming terminal, wherein the incomplete call information is recognizable incomplete call information or unrecognizable incomplete call information;

(d) transmitting request for message creating, which comprises the incomplete call information, to a calling information providing system;

(e) creating a message comprising a calling information providing;

(f) searching data such as the caller'"'"'s subscriber information, when message searching unit receives receivable state information of a incoming terminal;

(g) requesting message transmission for a message service center; and

(h) transmitting the message to the incoming terminal through an incoming MSC.

13. The method of claim 12, wherein if the incomplete call information is recognizable, then the method of step (f) further comprises the steps of:

storing the message;

receiving information regarding whether or not ready to be received;

receiving information regarding whether or not ready to be received from the incoming MSC through the HLR(home location register); and

extracting incomplete information corresponding to the incoming terminal.

14. The method of claim 12, wherein if the incomplete call information is unrecognizable, then the method of step (f) further comprises the steps of:

trying to connect a call to the incoming terminal;

creating the information of unrecognizable incomplete call when call connection fails; and

transmitting the information of unrecognizable incomplete call to the calling information providing system.

15. The method of claim 12, wherein the calling information providing system transmits the message by using a scheduling function periodically until the incoming terminal receives the message.

16. The method of claim 12, wherein the message comprises advertisement information or caller'"'"'s location information.

17. A method for providing a calling information of an incomplete call, comprising the steps of:

(a) receiving a call connection request comprising a caller'"'"'s number and an incoming subscriber'"'"'s number from a calling terminal;

(b) requesting routing information about an incoming MSC from an incoming MSC, to which an incoming terminal connects;

(c) receiving the routing information from the incoming MSC;

(d) requesting a call connection with the incoming MSC;

(e) extracting incomplete call information corresponding to the incoming terminal, wherein the incomplete call information is recognizable incomplete call information or unrecognizable incomplete call information;

21. The method of claim 17, wherein if the incomplete call information is unrecognizable, then the method of step (h) further comprises the steps of:

trying to connect the call to the incoming terminal;

creating the information of unrecognizable incomplete call when call connection fails; and

transmitting the information of unrecognizable incomplete call to the calling information providing system.
