ITU-T L.1330 (03/2015) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, i

7、nformation and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a

8、 worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down

9、 in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication a

10、dministration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory

11、provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attenti

12、on to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others o

13、utside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation.

18、 Bibliography. 29 iv Rec. ITU-T L.1330 (03/2015) Introduction Recommendation ITU-T L.1330 provides a set of metrics for the assessment of energy efficiency (EE) of telecommunication (TLC) mobile networks, together with proper measurement methods. Such metrics are of extremely high importance to oper

19、ators, given that the optimization of the energy performance of a single piece of equipment does not guarantee the overall maximum energy efficiency of a complex network formed by several interconnected equipments. Hence, through the metrics reported in this Recommendation, a better comprehension of

20、 network energy efficiency will be gained, not only for “total“ networks, but also for “partial“ networks, definable through either geographic or demographic boundaries. This Recommendation was developed jointly by ETSI TC EE and ITU-T Study Group 5 and published respectively by ITU and ETSI as Reco

21、mmendation ITU-T L.1330 and ETSI Standard ETSI ES 203 228, which are technically equivalent. Rec. ITU-T L.1330 (03/2015) 1 Recommendation ITU-T L.1330 Energy efficiency measurement and metrics for telecommunication networks 1 Scope This Recommendation aims to define the topology and level of analysi

22、s necessary to assess the energy efficiency (EE) of mobile networks. Within the scope of this Recommendation are the radio access parts of the mobile network, namely: radio base stations, backhauling systems, radio controllers and other infrastructure radio site equipment. The technologies covered a

23、re: global system for mobile communications (GSM), universal mobile telecommunications communications (UMTS) and long-term evolution (LTE) (including LTE advanced (LTE-A). In particular, this Recommendation defines metrics for mobile network energy efficiency and methods for assessing (and measuring

24、) energy efficiency in operational networks. The purpose of this specification is to allow better comprehension of network energy efficiency. This Recommendation deals with both homogeneous and heterogeneous “networks“ and considers networks whose size and scale could be defined by topologic, geogra

25、phic or demographic boundaries. For networks defined by topologic boundaries, a possible example of a network consists of a control node (whenever applicable), its supported access nodes, as well as its related network elements. Networks could also be defined by geographic boundaries, such as citywi

26、de, national or continental networks or by demographic boundaries, such as urban or rural networks. This specification applies to the so-called “partial“ networks where energy efficiency is measured in a standardized way. This specification extends the measurements in partial networks to wider so-ca

27、lled “total“ network energy efficiency estimations (e.g., the network in a geographic area, the network in an entire country, the network of a mobile network operator (MNO). Terminal (end-user) equipment is outside the scope of this Recommendation and thus, is not considered in the energy efficiency

28、 measurement. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.
