摘要： A terminal having a stream control transmission protocol (SCTP)-based handover function and a SCTP-based handover method are provided. The terminal includes a session management unit which initiates a SCTP session for communication with a second terminal through the Internet and terminates a SCTP session established between the terminal and the second terminal for terminating communication between the terminal and the second terminal; a link layer information collection unit which receives beacon signals from a plurality of base stations connected to a router which is connected to the Internet and stores the beacon signals in a link layer state information database; a signal intensity extraction unit which, if theterminal enters an overlapping area of a first communication area managed by a first base station and a second communication area managed by a second base station while the SCTP session is established between theterminal and the second terminal, extracts the intensity of a beacon signal transmitted by the second base station from the link layer state information database; and a handover unit which, if the extracted beacon signal intensity is greater than a first critical value, adds an IP address received from the second base station to the SCTP session established between the terminal and the other terminal, and if the extracted beacon signal intensity is greater than a second critical value, requests the second terminal to communicate with the terminal using the IP address received from the second base station. Accordingly, it is possible to reduce investment in network equipment and offer an efficient handover method by adding a SCTP stack to a mobile terminal.
