Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 4:
5. A network unit configured to enable management of random access attempts in a wireless communication system by a plurality of devices having wireless communication capabilities, the network unit comprising:
a processor; and
memory operatively coupled to the processor and storing program code for execution by the processor, whereby the network unit is configured to:
obtain information representing load of random access attempts;
determine, based on the information representing the load of random access attempts, control information for controlling a distribution of the random access attempts over time;
predict a burst of random access attempts by the plurality of devices based on the information representing the load of random access attempts; and
determine, in response to a predicted burst of random access attempts, the 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,
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.
