Abstract:
1. A method for adapting quality of service (QoS) mechanisms during, or in preparation of, a handover process for changing connection of a user equipment (UE) from a first point of attachment (PoA) of an access network (AN) to a target PoA of the AN, said AN capable of inner QoS mechanisms for maintaining quality of service (QoS) on a communication path within said AN for communication between said PoA and a network entity within said AN or a core network in connection with said AN, the method comprising: exchanging handover signalling messages between said first PoA and a second PoA during, or in preparation of, said handover process; sending, from said first PoA, a triggering message to said second PoA; receiving said triggering message at an UE proxy located on said second PoA, the UE proxy being configured to generate signals for controlling said inner QoS mechanisms; and at said UE proxy, in response to said triggering message, controlling said inner QoS mechanisms to ensure QoS on said communication path for said UE, wherein transmission of said generated signals for controlling said inner QoS mechanisms comprises excluding transmission of said generated signals to the UE such that said inner QoS mechanisms are unknown to said UE, and
