Dear all, we just submitted an update of the "Requirements for vertical handover of multimedia sessions using SIP" draft according to the comments received. Changes with respect to previous version: - Mentioned history of SIP mobility discussion in IETF - Introduced definition of Terminal Mobility and Session Mobility (extracted from the referenced paper "Application-Layer Mobility Using SIP" by Schulzrinne and Wedlund - Made references to 3GPP work on Voice Call Continuity and Multimedia Session Continuity - Clarified this draft addresses Terminal Mobility - Provided explanation about the relationship of this work with draft-shacham-sipping-session-mobility - Added references to two papers that compare mobility management approaches at different levels, from link layer to application layers We have also asked agenda time to shortly present at IETF 73 and ask the group what is the direction moving forward (maybe a design team?).
