According to a method of operating a cellular telecommunications network to implement self-organizing network (SON) functionality, a network manager (NM) SON function is implemented in a NM, and a plurality of network elements (NEs) each implement a NE SON function. Each NE SON function is associated with one or more network cells. The NM SON function obtains operational data relating to the network and evaluates a current network condition. Based on the current network condition, the NM SON function determines an allowable set of configuration parameters and conditional actions, which defines combinations of cell configuration parameters that a NE SON function is permitted to use when reconfiguring a 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 consistency and integrity of decisions taken at individual cells.
