The hybrid SON (H-SON) means the SON algorithm are executed at two or more of the following levels: NF layer, Domain layer or 3GPP Cross Domain layer. The hybrid SON concept has been defined for LTE in TS 32.500 [2].

The 3GPP management system (i.e. MnF(s) in Domain or 3GPP Cross Domain) and NFs work together, in a coordinated manner, to build up a complete SON algorithm. The decisions on SON actions may be made by 3GPP management system and/or NFs, depending on the specific cases.

Figure 4.1.4-1 shows that the C-SON component is monitoring and executes SON actions.
