To fully benefit from the all IP convergence, it should be possible for a user not only to access services


ubiquitously and at any time, but also to automatically and seamlessly transfer ongoing communication


between different devices. This article investigates the problem space of supporting Session Mobility (SM)


with IMS and the associated issues such as when and how to support dynamic changes in the set of


devices through which the user accesses a session. It also investigates how the SM arrival calls should be


handled at the network level where they are not considered as ongoing sessions. Hence, we discuss the


design options and identify functional blocks needed to support SM. We propose applying priority-based


resource allocation approach to guarantee lower blocking probability for ongoing SM arrival calls


compared to new arrival calls. Numerical results show that this approach allows achieving such


performance for different call arrival rates.
