Section: 6.15a.2.2 Requirements
Content: Subject to operator’s policy, the 5G system shall support subscription policies that define a maximum energy credit limit for services without QoS criteria. Subject to operator’s policy, the 5G system shall support a means to associate energy consumption information with charging information based on subscription policies for services without QoS criteria. Subject to operator’s policy, the 5G system shall support a mechanism to perform energy consumption credit limit control for services without QoS criteria. NOTE 1: The result of the credit control is not specified by this requirement. NOTE 2: Credit control [49] compares against a credit control limit. It is assumed charging events are assigned a corresponding energy consumption and this is compared against a policy of energy credit limit. It is assumed there can be a new policy to limit energy consumption allowed. Subject to operator’s policy, the 5G system shall support a means to define subscription policies and means to enforce the policy that define a maximum energy consumption (i.e. quantity of energy for a specified period of time) for services without QoS criteria. NOTE 3: The granularity of the subscription policies can either apply to the subscriber (all services), or to particular services. The 5G system shall provide a mechanism to include Energy related information as part of charging information. Subject to operator policy and agreement with 3rd party, the 5G system shall provide a mechanism to support the selection of an application server based on energy related information associated with a set of application servers. Subject to user consent and operator policy, 5G system shall be able to provide means to modify a communication service based on energy related information criteria based on subscription policies. Subject to user consent, operator policy and regulatory requirements, the 5G system shall be able to provide means to operate part or the whole network according to energy consumption requirements, which may be based on subscription policies or requested by an authorized 3rd party.
