Abstract

The embodiments herein relate to a method implemented in radio access node. The radio access node receives a list of prioritized Public Land Mobile Network (PLMN) Identities (IDs). The list of prioritized PLMN IDs comprises a PLMN ID of a serving PLMN and one or more PLMN IDs for one or more PLMNs of one or more shared networks. The radio access node instructs the wireless device to search for suitable cells for handover on at least one PLMN identified in the list of prioritized PLMN IDs and receives a list of suitable cells for handover. The radio access node determines a target PLMN ID and a target cell ID based on the list of suitable cells and the list of prioritized PLMN IDs. The radio access node initiates handover of the wireless device to a target cell identified by the target cell ID in the target PLMN.
