SESSION INFORMATION PROCESSING METHOD OF SESSION INITIATION PROTOCOL SYSTEM AND RECORDING MEDIUM THEREOF

摘要

PURPOSE: A session information processing method of an SIP(Session Initiation Protocol) system and a recording medium therefor are provided to easily control sessions by installing a session layer protocol between an SIP layer and UDP layer in an SIP stack. CONSTITUTION: An arbitrary message for requesting a call processing from a server is generated(S1). A session header including flag information and session identifier information are generated according to a type of the generated message(S2). The session header is added to the generated message(S3). A transmission layer header, a network layer header and a link layer header are sequentially added to the message(S4). The header-added message is transmitted to a server(S5). It is determined whether a header-added message is received from the server(S6). If a header-added message is received, the session header is parsed to extract the flag information and session identifier information from the session header(S7). A session is processed according to the extracted flag information and the session identifier information(S8).
