Section: 6.31.2.2 Disaster Condition
Content: The 3GPP system shall enable UEs to obtain information that a Disaster Condition applies to a particular PLMN or PLMNs. NOTE: If a UE has no coverage of its HPLMN, then obtains information that a Disaster Condition applies to the UE's HPLMN, the UE can register with a PLMN offering Disaster Roaming service. The 3GPP system shall support means for a PLMN operator to be aware of the area where Disaster Condition applies. The 3GPP system shall be able to support provision of service to Disaster Inbound Roamer only within the specific region where Disaster Condition applies. The 3GPP system shall be able to provide efficient means for a network to inform Disaster Inbound roamers that a Disaster Condition is no longer applicable. Subject to regulatory requirements or operator’s policy, the 3GPP system shall support a PLMN operator to be made aware of the failure or recovery of other PLMN(s) in the same country when the Disaster Condition is applies, or when the Disaster Condition is not applicable.
