NOTE 1: This requirement also include the condition when providing network elements or functions to an authorised 3rd party, the dynamic changes can be based on pre-configured policy (the time of changing energy states, which energy state map to which level of load, etc.)	PR 5.2.6-2
CPR 6.2-3	The 5G system shall support different charging mechanisms based on the different energy states of network elements and network functions.	PR 5.2.6-3	Charging aspect
