    Abstract: A user equipment starts a first timer in response to detecting a physical layer problem with a radio link between the user equipment and a node of a cellular network. Responsive to detecting a handover measurement event, the user equipment also starts a second timer and sends a measurement report to the node. The starting of the first and second timers causes the first and second timers to simultaneously elapse. Responsive to one of the simultaneously elapsing timers expiring, the user equipment sends a radio link failure report, to the node, indicating which of the simultaneously elapsing timers expired.
