Summary:碩士 === 靜宜大學 === 資訊管理學系研究所 === 93 === Beginning of the 90s’, all connection way is wire telephones or wireless cell phones. It is contained in Public Switched Telephone Network (PSTN). People will pay more cost to transport his/her voice to destination. The Internet rises and develops, the datacom companies get more opportunities to design low cost and high performance transmission ways. This technology is called Voice Over Internet Protocol (VoIP). The better of all solutions is Session Initiation Protocol (SIP) SIP is promising for VoIP signaling to support personal mobility. In this paper, we introduce and compare single registration (SR) and multiple registration (MR) for personal mobility. The SR scheme can not support personal mobility without user’s assistance. In contrast, the MR scheme supports personal mobility inherently using sequential search or pure parallel search. Sequential search may suffer from long delay for call setup, while pure parallel search consumes network resource. To compromise the two schemes, we propose pipelined search for multiple registration.
