1. A method performed by a Radio Access Network, RAN, node for supporting a Quality-of-Service, QoS, update during a Handover, HO, procedure, comprising:
providing a ‘support for reception of additional QoS parameters’ field in a Path Switch Request message to a Core Network, CN, node, wherein the ‘support for reception of additional QoS parameters’ field is configured to indicate whether the RAN node can support a QoS update during the HO procedure; and
performing one or more actions related to the HO procedure in accordance with the ‘support for reception of additional QoS parameters’ field provided to the CN node.
