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