Methods and apparatus for determining plmn with disaster condition

An apparatus of an Access and Mobility Management Function, AMF, for determining a Public Land Mobile Network, PLMN, with disaster condition in a wireless network, comprising:

• a memory;
• and
• at least one processor coupled to the memory, wherein the processor is configured to:
• receive a registration request message from a user equipment, UE;
• identify that a Fifth Generation System, 5GS, registration type information element, IE, in the registration request message is set to a “disaster roaming initial registration” or a “disaster roaming mobility registration updating”;
• identify whether a PLMN with disaster condition IE is included in the registration request message based on identifying that the 5GS registration type IE in the registration request message is set to the “disaster roaming initial registration” or the “disaster roaming mobility registration updating”;
• and
• determine a PLMN with disaster condition in the PLMN with disaster condition IE based on identifying that the PLMN with disaster condition IE is included in the registration request message.

A non-transitory computer readable storage medium storing instructions which, when executed by at least one processor of an apparatus of an Access and Mobility Management Function, AMF, in a wireless network, cause the apparatus perform operations, the operations comprising:

• receiving a registration request message from a user equipment, UE;
• identifying that a Fifth Generation System, 5GS, registration type information element, IE, in the registration request message is set to a “disaster roaming initial registration” or a “disaster roaming mobility registration updating”;
• identifying whether a PLMN with disaster condition IE is included in the registration request message based on identifying that the 5GS registration type IE in the registration request message is set to the “disaster roaming initial registration” or the “disaster roaming mobility registration updating”;
• and
• determining a PLMN with disaster condition in the PLMN with disaster condition IE based on identifying that the PLMN with disaster condition IE is included in the registration request message.
