Radio Access Network (RAN) - controlled inactive state. In some embodiments, a method of operation of a RAN node in a cellular Ir --- communications network comprises configuring a User Equipment (UE) with a timer value T for a periodic updating timer. In this 1-1 O manner, the RAN node is able to configure the UE with a time value T, e.g., for use by the UE for providing periodic update messages N while the UE is operating in an inactive state such as, e.g., a RAN-controlled inactive state.
