Abstract:Nowadays, almost every person uses mobile devices to communicate with other people on a daily basis. Those mobile devices keep renewing rapidly following the latest developments in communication technologies supporting higher bandwidth and the newest services. The development of these technologies make new types of personalized context-aware services possible. A typical goal of a personalized context-aware service could be to optimize the use of capable device in the close proximity of the user in ongoing communication sessions. This would typically be useful when a user who is engaged in an audio/video conference enters a meeting room. Whilst Upon entering, all media session components until then running on the PDA are transferred from the PDA to the projector, hi-set and webcam all present in the meeting room. When the user leaves the room all media components are transferred back to the PDA. Moving parts of a multimedia session between different devices is here defined as partial session mobility. For SIP numerous methods exist to enable partial session mobility both refer- and invite-based. None of those methods does support the ability to initiate partial session mobility from within the network, and especially not in combination with partial session mobility initiated by the user. Because of a number of advantages in the invite-based method, this method is taken as basis for the developement a method that supports both network initiated partial session mobility and user initiated partial session mobility.
