The invention relates to a method for address initialization in a communications system (1) comprising a control entity (10) and at least one network element (101, 102, 103, 110). The network element has an identifier (1012, 1022, Δt101, Δt102). The method comprises the sending of a message (210, 213, 410, 601, 604, 801, 804) from the network element to the control entity, the message being sent at a time (Τ101, Τ102) dependent on the identifier for the network element. The method further comprises the assignment of an address (1011, 1021, 1031) to the network element. The invention also relates to a communications system which is set up to execute the method, to a computer program comprising program code means for executing method steps and to a machine-readable storage medium comprising a computer program of this type.
