A method of operating a cellular telecommunications network to implement a self-organising network, SON, functionality is presented. A network manager, NM, SON function is implemented in a network manager, NM, and a plurality of network elements, NEs, each has a NE SON function implemented therein. Each NE SON function is associated with one or more network cells. The method comprises the NM SON function obtaining operational data relating to the network and evaluating a current network condition based on the operational data. Based on the current network condition, the NM SON function determines an allowable set of configuration parameters and conditional actions. The allowable set defines combinations of cell configuration parameters that a NE SON function is permitted to use when reconfiguring an associated cell. The NM SON function provides the allowable set in a NE configuration attribute sent to the NE SON function. The conditional actions are configured in the NE SON function and ensure the consistency and integrity of decisions taken at individual cells.
