5. The system of claim 1, wherein the calling information providing system further comprises a WAP server, which is a searching unit of incomplete call information that searches incomplete call information stored on the database server, and a callback unit that connects a call by a caller terminal corresponding to the caller information comprised in the incomplete call information.

6. The system of claim 1, wherein the calling information providing system further comprises an advertisement creator that creates an advertisement phrase.

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

8. 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 that identifies the incomplete call information.

9. 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.

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

(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 an incoming terminal;

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

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

wherein if the incomplete call information is unrecognizable, then the method of step (f) further comprises;

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.

11. The method of claim 10, wherein if the incomplete call information is recognizable, then the method of step (f) further comprises:

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.

12. The method of claim 10, wherein the calling information providing system transmits the message by using a scheduling function periodically until the incoming terminal receives the message.

13. The method of claim 10, wherein the message comprises advertisement information or caller'"'"'s location information.
