Enabling Service Continuity on Future Mobile Services

To be able to access services in a seamless way across different physical access networks is compelling. The seamless handover features and availability of the mobile voice telephony service is by far the most important key to success in current mobile telecommunication services. As mobile devices are becoming multi-modal, i.e., supporting several physical network access technologies, there has been much focus on enabling network handover between these access technologies. Unfortunately, seamless handover is not sufficient to ensure service continuity because in many cases, due to mobility not only the connection link must be changed but also the components realizing a service. In this paper extensions to the 802.21 MIHF to provide adequate assistance to the dynamic composition of a service is proposed and described thoroughly.
