1. A method performed by a first Radio Access Network, RAN, node for handling Quality of Experience, QoE, measurement configuration and/or reporting during RAN overload, the method comprising:
performing one or more actions related to one or more aspects of QoE measurement configuration, QoE measurement reporting, or both QoE measurement configuration and QoE measurement reporting that mitigate an RAN overload condition;
wherein performing the one or more actions comprises performing one or more actions related to transfer of one or more aspects of QoE measurement configuration from the first RAN node to a second RAN node, transfer of one or more aspects of QoE measurement reporting from the first RAN node to the second RAN node, or both;
wherein performing one or more actions related to transfer of one or more aspects of QoE measurement configuration from the first RAN node to a second RAN node, transfer of one or more aspects of QoE measurement reporting from the first RAN node to the second RAN node, or both comprises:
performing one or more actions to transfer responsibility of sending QoE measurement configuration(s) for one or more UEs from the first RAN node to the second RAN node,
performing one or more actions to transfer responsibility of sending QoE measurement configuration update(s) for one or more UEs from the first RAN node to the second RAN node, or
performing both one or more actions to transfer responsibility of sending QoE measurement configuration(s) for one or more UEs from the first RAN node to the second RAN node and one or more actions to transfer responsibility of sending QoE measurement configuration update(s) for one or more UEs from the first RAN node to the second RAN node.
