摘要： According to an aspect, there is provided a method performed by a first core network, CN, node in a telecommunication network. The telecommunication network comprises a first radio access network, RAN, node that operates according to a first radio access technology, RAT. An update to a first security configuration between a wireless device and the first RAN node is required. The method comprises, after receiving a request from the wireless device for an emergency session so that the wireless device can establish an emergency call, initiating (901) an Emergency Service Fallback procedure to a second RAT.

摘要： A source network node and a target network node, as well as respective methods performed thereby, for providing mobility to wireless devices are provided. The source and target network nodes are operable in a wireless communication network. The method (100) performed by the source network node comprises, when an uplink received signal quality from the wireless device does not meet a quality threshold, transmitting (130) scheduling information related to an upcoming uplink transmission of the wireless device to one or more potential target network nodes. The method further comprises obtaining (140) respective uplink signal quality for the respective potential target network node(s); and triggering (150) handover to a target network node if a handover criterion is fulfilled based on the respective uplink signal quality.

摘要： A source network node and a target network node as well as respective methods performed thereby for handing over a wireless device from the source network node to the target network node are provided. The method (100) performed by the source network node comprises requesting (130) the wireless device to perform measurement(s) on possible target network node(s) and the source network node; and obtaining (140) a measurement report from the wireless device comprising performed measurement(s) on at least one possible target network node, the performed measurements indicating received signal strength for signal(s) received from the at least one possible target node. The method further comprises determining (150) a first normalised Signal to Interference and Noise Ratio, SINR, associated with the received signal strength as measured by the wireless device for signals received from the source network node; and providing (160), to at least one of the at least one possible target network node, the determined first normalised SINR associated with the received signal strength for the source network node and the received signal strength of the at least one of the at least one possible target network node as received in the measurement report from the wireless device.
