Section: 5.40.3 Disaster Condition Notification and Determination
Content: The NG-RAN in the PLMN that provides Disaster Roaming service, broadcasts an indication of accessibility for Disaster Roaming service, and optionally, a 'list of one or more PLMN(s) with Disaster Condition for which Disaster Roaming service is offered by the available PLMN' in the impacted area as described in TS 38.304[ NR; User Equipment (UE) procedures in Idle mode and in RRC Inactive state ]  [50] and TS 38.331[ NR; Radio Resource Control (RRC); Protocol specification ]  [28]. A UE determines the Disaster Condition based on the information broadcasted from the NG-RAN providing Disaster Roaming service, and performs the network selection and the access control for the Disaster Roaming as described in TS 23.122[ Non-Access-Stratum (NAS) functions related to Mobile Station (MS) in idle mode ]  [17] and TS 24.501[ Non-Access-Stratum (NAS) protocol for 5G System (5GS); Stage 3 ]  [47]. NOTE 1: How a PLMN is notified that another PLMN is a PLMN with Disaster Condition and how a PLMN is notified of the area where the associated Disaster Condition applies is managed by the government agencies or the authorities, and is out of scope of 3GPP. NOTE 2: The broadcast for Disaster Roaming service from the NG-RAN occurs only during the Disaster Condition.
