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.
