A method of implementing a setup function for network automation functions, wherein the setup function is associated with a management domain of a network management system of a mobile communications network, wherein the management domain comprises one or more network automation functions , and wherein the management domain is associated with a specific level of a management domain hierarchy of the network management system, the method comprising: storing first information indicating descriptions and operational profiles of one or more first network automation functions of one or more first management domains of the network management system, wherein the first management domains are associated with a level L-1 of the management domain hierarchy; storing second information indicating management domain knowledge about one or more second management domains of the network management system, wherein the second management domains are associated with a level L of the management domain hierarchy higher than level L-1, and about the one or more first management domains; acquiring (S701) third information indicating a description of a third network automation function which is to be set up in a management domain of the first management domains associated with the level L-1; performing (S703) an evaluation of the third information against at least one of the first information and the second information; determining (S705) an operational profile of the third network automation function based on the evaluation; and setting up (S707) the third network automation function in the first management domain associated with the level L-1 by applying the operational profile to the third network automation function, wherein the management domain which the setup function is associated with is one of the second management domains associated with the level L, and wherein the method is performed by the setup function for network automation functions associated with the second management domain. storing first information indicating descriptions and operational profiles of one or more first network automation functions of one or more first management domains of the network management system, wherein the first management domains are associated with a level L-1 of the management domain hierarchy; storing second information indicating management domain knowledge about one or more second management domains of the network management system, wherein the second management domains are associated with a level L of the management domain hierarchy higher than level L-1, and about the one or more first management domains; acquiring (S701) third information indicating a description of a third network automation function which is to be set up in a management domain of the first management domains associated with the level L-1; performing (S703) an evaluation of the third information against at least one of the first information and the second information; determining (S705) an operational profile of the third network automation function based on the evaluation; and setting up (S707) the third network automation function in the first management domain associated with the level L-1 by applying the operational profile to the third network automation function, wherein the management domain which the setup function is associated with is one of the second management domains associated with the level L, and wherein the method is performed by the setup function for network automation functions associated with the second management domain. <EOS>
