A method in a telecom node for controlling a grace period associated with a licensed capacity usage in the telecom node is provided. The telecom node is comprised in a cellular telephone network. The licensed capacity usage is associated with a capacity license limit. The telecom node measures (201) over a specific amount of time, the capacity usage in the telecom node overshooting the capacity license limit. When the measured capacity usage exceeds a preset value of an allowed capacity usage overshoot, the telecom node triggers (202) a grace period of the licensed capacity usage at the expiry of the specific amount of time. During the grace period capacity usage overshoot is allowed. Upon expiry of said grace period the licensed capacity usage is enforced according to the capacity license limit unless the licensed capacity usage is increased.
