1. A method of operation by a network node of a wireless communication network comprising a Core Network (CN) and a satellite-based Radio Access Network (RAN) for communicatively coupling User Equipments (UEs) to the CN, the method comprising:
determining switch information regarding a forthcoming link change with respect to providing connectivity between a UE and the CN via the satellite-based RAN, the forthcoming link change being at least one of a service-link change or a feeder-link change arising from satellite movement, and the switch information indicating when the link change will occur;
sending the switch information to the UE, to control performance by the UE of Radio Resource Management (RRM) measurements with respect to the link change;
the UE having a current measurement configuration that is valid until the link change and governs the performance of RRM measurements by the UE in advance of the link change; and
sending a new measurement configuration one of in and in conjunction with the switch information, the new measurement configuration being valid after the link change and governing the performance of RRM measurements by the UE after the link change.
