Abstract: Where a UE moves between primary and/or secondary cells, the repeated reconfiguration of a UE at the network requires repeated signalling. Where non terrestrial networks nodes provide cells it may be possible to predict which cells a UE is likely to visit and when, based on the satellite movement. Embodiments make use of this ability to predict multiple future cells by transferring configuration information for a series of target cells in a single message, in some cases along with condition information indicating when the cell is likely to be providing radio coverage for that UE. Furthermore, to reduce signalling overhead some of the information is provided as a delta information, that is as an indication of how a previous configuration will change to provide the new configuration. A UE can apply the configuration information as the conditions become fulfilled.
