    摘要： Systems and methods are disclosed herein for Quality of Experience (QoE) measurements handling at overload in a Radio Access Network (RAN) of a cellular communications system. In one embodiment, a method performed by a first RAN node for handling QoE measurement configuration and/or reporting during RAN overload comprises 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. In one embodiment, 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.

    摘要： A method performed by a first network node for assisting a second network node in resuming of a User Equipment, UE, in inactive state into connected state in a Radio Access Network, RAN. The first network node obtains (401) a Local RAN Node Identifier associated with a Public Land Mobile Network, PLMN, RAN Node ID, identifying the first network node. The first network node sends (402) the Local RAN node Identifier and associated PLMN RAN Node ID to be obtainable by the second network node. The first network node suspends (403) the UE from connected state into inactive state and sends an identifier to the UE. The identifier comprises a UE Context ID and the associated Local RAN Node Identifier. The UE Context ID identifies the UE context associated with the UE. The UE Context ID, Local RAN Node Identifier and associated PLMN RAN Node ID will assist the second network node to obtain the UE Context for the resuming of the UE into connected state, wherein a connection is to be provided by the second network node.

    摘要： Embodiments include methods, performed by a user equipment, UE, for reporting failures related to mobility operations by the UE to a network node in a radio access network, RAN. Such methods include logging (1210) information associated with a plurality of failures during conditional handover, CHO, operations related to a source cell and one or more first target cells. Such methods also include, after a successful mobility operation to a second target cell served by the network node, reporting (1240) the logged information, associated with the plurality of failures, to the network node. Other embodiments include complementary methods performed by a network node, as well as UEs and network nodes configured to perform such methods.
