摘要
A method for supporting quality of service (QoS) mechanisms during a handover process or in preparation of a handover process, wherein a user equipment (UE) attaches to an access network (AN) via points of attachment (PoA), wherein said handover process supports changing connection of said UE from one of said points of attachment - current PoA - to another one of said points of attachment - target PoA - while maintaining all ongoing connections of said UE, wherein signalling messages are exchanged between said current PoA and a second PoA during or in preparation of said handover process, said second PoA comprising said target PoA or a candidate for said target PoA, and wherein said AN supports inner QoS mechanisms on a communication path within said AN, said communication path being used for communication between one of said PoA and a core network (CN) or between one of said PoA and a network entity within the AN, is characterized in that a triggering message is sent to said second PoA by said current PoA, said triggering message being received by an UE proxy located on said second PoA, wherein said UE proxy, in reaction to said triggering message, controls said inner QoS mechanisms to ensure QoS on said communication path.
