Abstract: An embodiment may comprise: transmitting, by a user device in a low activity state a type of the low activity state being according to an anchor access node, a random access message to a network node providing a target cell of a cell reselection. The method may also comprise, in response to receiving a random access response for the random access message from the network node providing the target cell, transmitting, to the network node providing the target cell, a radio connection reactivation request, the reactivation request comprising an indication of an anchor access node of the user device. The method may also comprise, in response to the radio connection reactivation request, receiving a radio connection reactivation message indicating a radio connection reactivation to the anchor access node as a logical link associated with a radio link provided by the target cell of the cell reselection or receiving an inactivation message.

Abstract: An apparatus comprising means for performing: receiving, while connected to a first cell, preparation information for preparing the apparatus for a conditional handover of the apparatus to at least one other cell; receiving, from the first cell, a message, wherein the message causes the apparatus to transition from a connected state to an inactive state; receiving, from the first cell, information of a release condition; when it is determined that the release condition is met, sending a release indication and releasing the preparation information from the apparatus.
