A wireless telecommunication system, a node (e.g., eNodeB, BSC, RNC), a procedure latency monitor unit, and a method are described herein for measuring the latency of a procedure (e.g., radio network procedure, core network procedure) where the results of the measured latency may be used for admission control of user equipment (UE) sessions and to guarantee that admitted UEs are served according to their requested Quality of Service (QoS).
