Summary:The present invention relates to a method in which an intelligent supplementary service providing system operated by at least one processor provides an intelligent supplementary service to a caller terminal and a receiver terminal through which a call is connected. According to the present invention, when the caller terminal receives an INVITE message transmitted to the receiver terminal from a session control device, information of the intelligent supplementary service subscribed by the caller terminal is checked based on identification information of the caller terminal included in the INVITE message. In addition, resources for providing the intelligent supplementary service subscribed by the caller terminal are allocated. When a call media packet is received from the caller terminal as the caller terminal and the receiver terminal are connected, a call media packet is transferred to an application server which provides the intelligent supplementary service using resources. Moreover, when received by the application server, the call media packet reflecting the intelligent supplementary service is transferred to the receiver terminal. Accordingly, convenience for users on the phone can be improved. 적어도 하나의 프로세서에 의해 동작하는 지능형 부가 서비스 제공 시스템이, 통화 호가 연결된 발신자 단말과 착신자 단말에 지능형 부가 서비스를 제공하는 방법으로서, 발신자 단말이 착신자 단말로 전송한 INVITE 메시지를 세션 제어 장치로부터 수신하면, INVITE 메시지에 포함된 발신자 단말의 식별 정보를 기초로 발신자 단말이 가입한 지능형 부가 서비스의 정보를 확인한다. 발신자 단말이 가입한 지능형 부가 서비스를 제공하기 위한 자원을 할당하고, 발신자 단말과 착신자 단말의 통화 호가 연결되어 발신자 단말로부터 통화 미디어 패킷을 수신하면, 자원을 이용하여 지능형 부가 서비스를 제공하는 어플리케이션 서버로 통화 미디어 패킷을 전달한다. 그리고 어플리케이션 서버에서 지능형 부가 서비스가 반영된 통화 미디어 패킷을 수신하면 착신자 단말로 전달한다.
