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: Embodiments of a network selection method and a related apparatus are provided. In the method, an apparatus receives a broadcast message from a non-forbidden public land mobile network (PLMN) and a broadcast message from a forbidden PLMN. The broadcast message of the forbidden PLMN includes a disaster occurrence indication, and the disaster occurrence indication indicates that a disaster has occurred on the non-forbidden PLMN. The apparatus requests, based on the disaster occurrence indication, to register with the forbidden PLMN, when the apparatus fails to register with the non-forbidden PLMN. According to the foregoing method, the apparatus can select a network that ensures a normal service, and a service interruption to the apparatus caused by the disaster that occurs on the non-forbidden PLMN can be effectively reduced.

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.

Abstract: The disclosure relates to early detection and indication of a Quality-of-Service (QoS) non-fulfillment in one or more radio links serving an application. A client device monitors for a QoS non-fulfillment in the one or more radio links based on a QoS monitoring configuration associated with the application. The QoS monitoring configuration may be received from a network node and/or derived based on a predefined rule. Upon detection of a QoS non-fulfillment of one or more QoS requirements obtained from the QoS monitoring configuration, the client device provides a QoS non-fulfillment indication to the application. The QoS non-fulfillment indication gives the application an early warning about QoS non-fulfillment on the one or more radio links. Thereby, allowing the application to take precautionary actions to counteract possible negative consequences of the QoS non-fulfillment. Furthermore, the disclosure also relates to corresponding methods and a computer program.
