Publication number: 20230337167Abstract: A client device for efficient disaster handling based on a novel list of PLMNs for disaster conditions. The client device is provided with a list of PLMNs that is used by the client device in response to the serving PLMN of the client device going into a disaster condition. Upon determining that the serving PLMN is in a disaster condition, the client device registers at a visiting PLMN in the PLMN list. The novel list of PLMNs for disaster conditions enables the client device to roam into PLMNs which is forbidden during normal conditions.Type: ApplicationFiled: June 20, 2023Publication date: October 19, 2023Inventors: Vishnu PREMAN, Rama Kumar MOPIDEVI, Gong CHEN, Xibo SUN, Jianhai CUI, Linping YANG
