Claim 0:
1. A method, performed by a network unit, for enabling management of random access attempts in a wireless communication system by a plurality of devices having wireless communication capabilities, wherein the method comprises:
obtaining information representing load of random access attempts; and
determining, based on the information representing the load of random access attempts, control information for controlling a distribution of the random access attempts over time,
wherein the control information is represented by a delay indicator that represents a relative delay value informing each device to spread random access attempt of the corresponding device in a fraction of a predefined device-specific maximum delay value, and
wherein the distribution of the random access attempts comprises:
selecting a desired value for a random access delay indicator based on current load or historical load at a current time of a day; and
preparing a System Information Block that is to be updated according to the selected value of the random access delay indicator,

wherein the step of determining control information for controlling a distribution of the random access attempts over time comprises:
predicting a burst of random access attempts by the plurality of devices based on the information representing the load of random access attempts; and
determining, in response to a predicted burst of random access attempts, control information for enabling the plurality of devices to distribute the random access attempts over a period of time to at least partly prevent the burst of random access attempts.
