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: The invention relates to detection and indication of non-fulfillment of latency requirements of uplink data packets associated with an application. A client device monitors transmissions of uplink data packets associated with the application, in a first layer, for non-fulfillment of latency requirements of the uplink data packets. The monitoring is based on a QoS monitoring configuration. Upon detection of a non-fulfillment of a latency requirement, the client device provides a first indication to a second layer. The first indication provides an early warning about non-fulfillment of latency requirements of uplink data packets. Thereby, allowing the client device to take precautionary actions to counteract possible negative consequences of the non-fulfillment of latency requirements. Furthermore, the invention also relates to corresponding methods and a computer program.

Abstract: Example methods and client devices and network access nodes for link failure recovery in connected-mode-discontinuous-reception (C-DRX) mode are described. In one example method, the client device performs beam/link monitoring according to a first link recovery procedure if the client device is in non-discontinuous-reception (non-DRX) mode operation with a network access node. The client device performs beam/link monitoring according to a second link recovery procedure if the client device is in C-DRX mode operation with the network access node.

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.

Abstract: The present disclosure relates to client devices and methods for link failure recovery in discontinuous reception (DRX) in connected mode (C-DRX). One example client device is configured to perform beam/link monitoring according to a link recovery procedure if the client device is in a C-DRX mode operation with a network access node, where a configured beam failure detection (BFD) timer of the link recovery procedure is a function of a periodicity of beam failure indications.
