Foreword This ETSI Standard (ES) has been produced by ETSI Technical Committee Environmental Engineering (EE). Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “
17、may not“, “need“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. Introducti
18、on Energy efficiency is an increasingly important requirement for all modern systems. Governments, communication service providers, vendors, etc. do all agree that energy efficiency is a critical “piece“ in the joint strive for a more sustainable society. With the present document, the industry gets
19、 a jointly agreed definition of metrics and measurement methods that - over time - can serve as a platform to excel, measure, and report energy efficiency of the core networks of telecommunication systems. The present document provides robust and reproducible measurements for products used in core t
20、elecom networks. The present document defines energy efficiency metrics and measurement methods for mobile core equipment. In later revisions Base Station Controller (BSC) and IMS core will be added. Energy efficiency is defined as useful output normalized to energy consumption, and the assumption i
21、s that an energy efficient system handles more calls, subscribers, etc., with less energy. The present document promotes energy saving features as the traffic profile is a representation of the expected behaviour of the equipment in operation, i.e. the power consumption is measured at different load
22、 levels when processing traffic mimicking a typical usage of the equipment. The defined metrics can be used for comparing energy efficiency of different implementations (HW and SW) of the same function only. Energy efficiency of co-located functions can however not be compared using the methodology
23、defined in the present document. ETSI ETSI ES 201 554 V1.2.1 (2014-07) 51 Scope The present document defines metrics and measurement methods applicable for the following systems and nodes defined in TS 123 002 i.3: Mobile core functions (GGSN, HLR, MGW, MME, MSC, SGSN and PGW/SGW).

44、he total power consumed by the device or shelf/shelves is/are measured and not different parts of the device or shelf/shelves. A “black box“ can be viewed solely in terms of its input, output and transfer characteristics without any knowledge of its internal workings. Figure 2: Measurement set-up of
45、 system under test 4.2 Site energy consumption Energy consumption at site includes also climate units, losses, auxiliary equipment, etc. These aspects are not observed in the present document. 4.3 Power consumption The defined traffic profile mimics the behaviour of a function in operation (i.e. wit
46、h load level variations) and the resulting performance indicators constitutes of a weighted average of multiple measurements. The load levels are defined as: Specification: TS- the maximum capacity according to the vendors specification of the specific implementation of the function High: TH= 1,0 TS
47、 Mid: TM= 0,7 TS Low : TL= 0,1 TSAs the present document defines metrics and measurements for a wide variety of implementations of functions - operating in control and/or user planes as well as circuit switched and/or packet switched domains - further details on the traffic models are specified per
48、function in annexes A to G. The power consumption levels associated with the above load levels are defined as: High: PH= average power consumption W measured at TH Mid: PM= average power consumption W measured at TM Low: PL= average power consumption W measured at TLETSI ETSI ES 201 554 V1.2.1 (2014
49、-07) 10The average power consumption is defined as: Pavg= PL+ PM+ PHW (1a) Where , , and are weight coefficients selected such as ( + + ) = 1. The inclusion of power consumption at TM, and TLhighlights the importance of Power saving features. See annexes A to G for further details. 4.4 Shaping of weight coefficients Although the functions included in the present document are heterogeneous in the sense that they operates in control and/or user planes as well in circuit switched and/or packet switched domain
