Abstract:
1. Method for supporting handover mechanisms, in particular Media Independent Handover (MIH) mechanisms, wherein a user equipment (UE) attaches to an access network (AN) via points of attachment (PoAs), wherein signalling messages are exchanged between the entities participating in said handover process, in particular between said user equipment (UE) and said points of attachment (PoAs), and wherein said handover mechanism supports changing the network connection of said user equipment (UE) from one of said points of attachment (PoAs)—current point of attachment (PoA) —to another one of said points of attachment (PoAs)—target point of attachment (PoA)—while maintaining all ongoing communication of said user equipment (UE), said method comprising adding information about said user equipment's (UE) ongoing communication to said signalling messages exchanged in said handover process such that individual flow related information of said user equipment's (UE) ongoing flows is included in said signaling messages, and employing said information to treat individual traffic flows of said user equipment's (UE) ongoing communication selectively during said handover process, wherein said information added to said signalling messages includes information regarding each flow's priority and/or importance as absolute value or relative to other flows.
