Abstract: 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.

The handover report includes, for at least one detected cell exceeding the measurement threshold, a physical cell identifier for the detected cell and a frequency identifier for the detected cell.
