Quality of service (QoS) refer to the network measurement of the overall performance about a communication service for the user. This network performance statistic can be e.g, packet loss, data rate, transmission delay, jitter, etc. When provide the energy as a service or a network performance criteria, e.g. in clause 5.2, the industrial park customer can be provided different energy-related SLAs under different energy states of network by operator, it is reasonable that not only the energy consumption information of the network or network functions but also the associated network performance statistic information are collected and exposed together to the customers or authorized third parties which will help customers to achieve more visible network service under different energy states of network functions. The network performance statistic information can be pre-configured by the customer, authorized third parties or by Operator to be associated with the network functions energy consumption information. The network performance statistic information can be packet loss, data rate, transmission delay, jitter, etc. which can be collected and calculated the average value based on 5QI refer TS 28.554.

The network Operator deploys 5G NPN network in industrial park to provide energy as a service "GreenPark" for the industry park customer M. The "GreenPark" service can provide high data rate communication service and higher reliability service either. The industry customer M has subscribed the high data rate service with SLA "H". The network Operator also provides a replaceable SLA "E2H" which can be used during off-peak working time. This replaceable SLA can reduce energy consumption by changing the energy state of a cell, a network element and/or a network function belong to the 5G NPN (e.g. to "energy saving" state), and the action can be activated either by pre-configured policy or by notification from customer M.

1. Customer M asks the "GreenPark" Operator to provide the "GreenPark" energy consumption information and its communication services network performance statistic information (e.g. the data rate, packet delay and packet loss) per hour during the working time (e.g. from 9am to 5pm) in the industrial park.
2. The operator acquires the energy consumption information of the 5G NPN serving customer M every hour.
3. At the same time, operator collects the network performance statistic information (e.g. average data rate, average packet delay and average packet loss) from the 5G NPN serving customer M every hour.
4. The operator provides the energy consumption information of the 5G NPN serving the customer M and the network performance statistic information from the 5G NPN e.g. the average data rate, average packet delay and average packet loss during the working time in the industrial park.
5. According to the pre-configured policy with customer M, the Operator changes the energy state of the 5G network functions of the 5G NPN serving customer M for energy saving. The operator continues to acquire the energy consumption information and collects the network performance statistic information from the 5G NPN under new energy state and provides this information together to the customer M.

Customers M can get the not only the energy consumption information but also the average data rate, average packet delay and average packet loss from 5G NPN during the working time and off-peak working time.

The QoS monitoring requirements have been specified in clause 6.23 of TS 22.261. But it has not any consideration on energy consumption. Some related requirements are listed below: The 5G system shall be able to provide real time QoS parameters and events information to an authorized application/network entity. The 5G system shall support different levels of granularity for QoS monitoring (e.g. per flow or set of flows) The 5G system shall support an update/refresh rate for real time QoS monitoring with a specified value (e.g., at least one update per second) In TR 28.829, there are solutions of collect network information of energy utility via OA&M. In clause 4.6 of TR 28.913 the key issue is to add reliability KPI into the URLLC network slice energy efficiency formula. In this key issue, the energy efficiency is calculated in the 3GPP domain, the related information is not exposed together to external.
