Method for supporting handover mechanisms

Method for supporting handover mechanisms, in particular Media Independent Handover (MIH) mechanism according to the IEEE 802.21 standard,

• 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),
• characterized in that information about said user equipment's (UE) ongoing communication is added to said signalling messages exchanged in said handover process,
• wherein said information is employed to treat individual traffic flows of said user equipment's (UE) ongoing communication selectively during said handover process.
