Abstract

Session Initiation Protocol (SIP) has been widely applied to telephony service. SIP is also adopted as the signal communication protocol of VoIP and 3GPP, so the development of SIP receiving much concern. Currently the research of SIP can be divided into four issues, including terminal mobility, session mobility, personal mobility, and service mobility. In this paper, we address the issue of session mobility. We want to solve the problem allowing a user to transfer, split, and retrieve a session over multiple devices by using SIP. In order to provide the service, three new agents have been introduced based on the definition of user agent proposed in RFC 3261. There are session manager, session user, and free node. Based on these agents, we propose a complete mechanism, to transfer and retrieve a session over multiple devices. According to our mechanism, the user will facility transfers, splits, and retrieves a session over multiple devices. Finally, we implement the mechanism by modifying the open source project of "Sip-Communicator".
