Methods, apparatus, and systems using closed access group (CAG) support in minimization of service interruptions (MINT)

A method implemented by a wireless transmit/receive unit (WTRU) using a first Public Land Mobile Network (PLMN) not affected by a disaster condition and a second PLMN affected by a disaster condition, the method comprising:

• receiving, by the WTRU from a Closed Access Group (CAG) cell of the first PLMN, broadcast information indicating that the CAG cell supports disaster roaming (DR) of WTRUs associated with the second PLMN;
• sending, by the WTRU to a network entity, a registration request message including information indicating a DR indication and an identifier of the second PLMN;
• receiving, by the WTRU, CAG information associated with the first PLMN, the CAG information indicating CAGs allowed for DR in the first PLMN;
• storing the received CAG information associated with the first PLMN which is indicated as reserved for DR;
• selecting, by the WTRU, the CAG cell of the first PLMN based on the broadcast information, wherein the broadcast information further indicates that the CAG Cell accepts CAG-supporting disaster roamers;
• initiating, by the WTRU, a cell selection procedure or a cell reselection procedure using the received CAG information associated with the first PLMN.
