No. US 2023/0269689) teaches a method for timer T adjustment due to disaster roaming occurrence, and an apparatus for supporting same. A user equipment (UE) determines that a disaster condition applies to a home public land mobile network (HPLMN). Upon selecting a disaster roaming PLMN, the UE performs a first registration procedure for disaster roaming services on the disaster roaming PLMN, and periodically attempts to obtain service on the HPLMN based on a timer T with a first value. Upon selecting a Visited PLMN (VPLMN), the UE performs a second registration procedure on the VPLMN, and periodically attempts to obtain service on the HPLMN based on a timer T with a second value. In some details, the method provides the most efficient way to prevent interruption of communication services in the event of a disaster is to use roaming. That is, if communication service cannot be received from the communication operator to which the user subscribed due to a disaster, interruption of communication service can be prevented by roaming to another nearby communication operator's network to receive communication service. More specifically, each communication operator may actively install a wireless network and a core network in an area (e.g., one country) for which it is licensed. Different communication operators may construct networks in different ways and/or install core network nodes in different buildings, so even if a disaster occurs, it may not affect all communication operators equally. That is, a problem that occurs in one communication operator may not be equally likely to occur in another communication operator. Starsinic (Pub. No. US 2024/0007878) teaches user equipment (UE) may detect a disaster condition, based on broadcast information, RRC messaging, NAS messaging, the ability to connect to an allowable PLMN, and indications from forbidden PLMNs. In a disaster condition, a UE may perform an enhanced PLMN selection procedure wherein, for example, the UE will not consider PLMNs that are in a disaster situation if the disaster situation applies to a current location of the UE, prioritize forbidden PLMNs for disaster roaming connection. For disaster roaming connection, the UE may be configured by an otherwise forbidden PLMN with information about what services the UE can access and what type of authentication procedure the network is able to perform with UE. Upon detecting that the disaster condition is over, the UE move back to an allowable PLMN.
