Document Type and Number:
Japanese Patent JP5266387
Kind Code:
B2
Abstract:
A 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 the handover process, in particular between the user equipment and the points of attachment, and wherein the handover mechanism supports changing the network connection of the user equipment from one of the points of attachment—current point of attachment (PoA)—to another one of the points of attachment—target point of attachment—while maintaining all ongoing communication of the user equipment, is characterized in that information about the user equipment's ongoing communication is added to the signalling messages exchanged in the handover process, wherein the information is employed to treat individual traffic flows of the user equipment's ongoing communication selectively during the handover process.
