Abstract: 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.

Abstract: A network node for a communication system is associated with a serving public land mobile network (PLMN) for a first client device. The network node is configured to transmit a first control message to the first client device in response to determining that the serving PLMN for the first client device is in a disaster condition. The first control message indicates that the serving PLMN for the first client device is in the disaster condition.
