2 Page 2Version 1.0 IEEE 802 March 2011 workshop EEE 802 What is IEEE ? Media Independent Handover (MIH) Services A framework that helps improving the user experience of mobile device by facilitating handover between heterogeneous access networks Features A shim layer that enables the transparent service continuity Provide link layer intelligence to upper layers to optimize handovers with network discovery and handover command capabilities Does not define policies and inference engine required to optimize user experience during a handover
