Section: 6.15a.4.2 Requirements
Content: Subject to operator's policy, the 5G network shall support energy consumption monitoring at per network slice and per subscriber granularity. NOTE 1: Energy consumption monitoring as described in the preceding requirement is done by means of averaging or applying a statistical model. The requirement does not imply that some form of 'real time' monitoring is required. The granularity of the subscription policies can either apply to the subscriber (all services), or to particular services. Subject to operator’s policy and agreement with 3rd party, the 5G system shall be able to monitor energy consumption for serving this 3rd party. NOTE 2: The granularity of energy consumption measurement could vary according to different situations, for example, when several services share a same network slice, etc. NOTE 3: The energy consumption information can be related to the network resources of network slice, NPNs, etc. Subject to operator policy and regulatory requirements, the 5G system shall be able to monitor the energy consumption for serving the 3rd party, together with the network performance statistic information for the services provided by that network, related to same time interval e.g. hourly or daily. NOTE 4: The network performance statistic information could be the data rate, packet delay and packet loss, etc.
