Section: 6.31.2.3 Disaster Roaming
Content: The 3GPP system shall be able to provide means to enable a UE to access PLMNs in a forbidden PLMN list if a Disaster condition applies and no other PLMN is available except for PLMNs in the forbidden PLMN list. The 3GPP system shall provide means to enable that a Disaster Condition applies to UEs of a specific PLMN. The 3GPP system shall be able to provide a resource efficient means for a PLMN to indicate to potential Disaster Inbound Roamers whether they can access the PLMN or not. Disaster Inbound Roamers shall perform network reselection when a Disaster Condition has ended. The 3GPP system shall minimize congestion caused by Disaster Roaming. The 5G system and EPS shall support a mechanism for the HPLMN to control whether a UE, with HPLMN subscription, should apply Disaster Roaming when a Disaster Condition arises (in the HPLMN or a VPLMN). 3GPP system shall be able to collect charging information for a Disaster Inbound Roamer with information about the applied disaster condition.
