1. An apparatus comprising:
at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
obtain, at a target node, information indicating a cell clearance is to be carried out for secondary users under authorized shared access concept of at least one neighbor cell;
convey information to the at least one neighbor cell on resources allocable to traffic in relation to the cell clearance, wherein the information on resources comprises maximum number of user devices the target node is able to provide service for, maximum total or aggregated guaranteed bit rate for the traffic in relation to the cell clearance, and/or timing parameter specifying a period of time the resource information is valid;
obtain information on traffic transfers to be handed over from the at least one neighbor node to the target node for the cell clearance;
reserve, by the target node, temporal physical random access channel resources from a physical uplink shared channel for the traffic transfers, and
carry out handover procedures to the target node for the traffic transfers.
