Abstract: Methods, devices, apparatuses, and computer readable medium for enhancements on service continuity. The method includes receiving, at a source network node and from a user equipment, UE, being served by the source network node for a service associated with a network slice, a message indicative of a target network node for a handover of the UE from the source network node to the target network node; transmitting a handover request to the target network node, the handover request indicating urgency of the handover for the UE, and the target network node being overloaded for the network slice; and receiving a handover request acknowledgement message from the target network node, the handover request acknowledgement message indicating if multi-carrier radio resource sharing is applicable for supporting the service.

Abstract: There is provided an apparatus for a terminal, the apparatus comprising means configured to perform: receiving a message from a serving cell, wherein the message comprises a configuration for a measurement event and a configuration for a conditional handover, the configuration for the measurement event comprising a leaving condition. The means are further configured to perform, in response to measuring the leaving condition of the measurement event being met, incrementing a counter, and when it is determined that the counter has reached a threshold value, deactivating the received configuration for the conditional handover and providing a measurement report to the serving cell, the measurement report indicating that the leaving condition of the measurement event has been met.

Abstract: The present disclosure relates to a technique for enabling secondary-cell (SCell) operation during dual active protocol stack handover (DAPS-HO). For this purpose, a command for the DAPS-HO is modified at a source network node such that it causes a UE to maintain, among an available set of source SCells configured by the source network node for the UE, at least one source SCell active during the DAPS-HO, as well as to activate, among an available set of target SCells configured by a target network node for the UE, at least one target SCell during the DAPS-HO. By using such a modified command for the DAPS-HO, the UE may use the SCells of the source and target network nodes during the DAPS-HO, thereby resulting in a higher user plane throughput compared to that provided by using the single PCell operation only.

Abstract: There is provided a method, computer program, and apparatus for causing an apparatus for a first access node to perform: establishing a connection towards a user equipment via a serving cell supported by the first access node; instructing the user equipment to obtain a first timing advance value for a target cell supported by a second access node, wherein the first timing advance value indicates a timing for transmitting uplink transmissions to the target cell; receiving, from the user equipment, an indication that the first timing advance value is or will soon be invalid; and determining whether to instruct the user equipment to obtain a second timing advance value for the target cell in dependence on the received indication, the second timing advance value being obtained later in time than the first timing advance value.
