ption of the basic and additional set of PLMN IDs. The available core network operators must be the same for all cells of a TA in a shared NG-RAN network. The UE decodes the broadcast system information and takes the information concerning the avail- able PLMN IDs into account in the network and cell (re-)selection procedures. A UE that has a subscription to a participating operator in a network sharing scenario must be able to select this participating network operator while present within the cover- age area of the shared network and to receive subscribed services from the participating network operator. Each cell in the shared NG-RAN must include the PLMN-IDs corre- sponding to the available core network operators in the shared network in the broadcast 5G Network Architecture 111 system information. When a UE performs an initial access to a shared network, one of the available PLMNs is selected to serve the UE. The UE uses all received broadcast PLMN- IDs in its PLMN (re) selection processes and informs the NG-RAN of the selected PLMN SO that the NG-RAN can properly route its traffic. After initial access to the shared net- work, the UE does not switch to another available PLMN as long as the selected PLMN is available to serve the UE at its present location. The network does not move the UE to another available PLMN by handover as long as the selected PLMN is available to serve the UE. The NG-RAN uses the selected PLMN information, which is provided by the UE at RRC establishment or provided by the AMF/source NG-RAN at N2/Xn handover, to select target cells for future handovers and allocation of radio resources. In case of hand- over to a shared network, the NG-RAN selects a target PLMN based on either PLMN in use, preset configuration, or the equivalent PLMN list in the handover restriction list pro- vided by the AMF. For Xn-based handover procedure, the source NG-RAN indicates the selected PLMN ID to the target NG-RAN by using target cell ID. For N2-based hand- over procedure, the NG-RAN indicates the selec
