Section: 6.15a.2.1 Description
Content: Energy consumption can be monitored and considered through O&M as part of network operations [47], as well as a service criteria. For best-effort traffic, that is, without QoS criteria, policies can be defined to limit energy use for services. This is not in conflict with the principle that performance policies will not be traded off for energy efficiency, since best-effort service has no performance guarantees. Specifically, best-effort traffic can be subject to a policy that limits the maximum energy consumption over time, or further constrained by location (so that the energy consumption limit only applies when used in a specified service area.) Additionally, policies can be defined with a maximum energy credit limit, e.g. for best-effort services to limit the total amount of energy consumption according to an energy charging rate. These policies expand the options of subscription policies to control energy consumption in the 5G system.
