35、 21.905 1 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905 1. Centralized ES: ES solution where ES algorithms are executed in the OAM system. Centralized ES has two variants: ETSI ETSI TS 132 551 V14.0.0 (2017

36、-04)63GPP TS 32.551 version 14.0.0 Release 14- NM-Centralized ES: ES solution where ES algorithms are executed at the Network Management level. - EM-Centralized ES: ES solution where ES algorithms are executed at the Element Management level. Distributed ES: ES solution where ES algorithms are execu

37、ted at the Network Element level. notEnergySaving state: the default state in peak-traffic situation, with no specific energy saving in progress. energySaving state: in an off-peak-traffic situation, some functions of a cell or a network element are powered-off or restricted in resource usage in oth

38、er ways, whereas the cell or network element is still controllable. ES Probing procedure : Upon being triggered by the Cell Activation Request message - of the Cell Activation procedure (see TS 36.300 10 section 20.2.2.15) - sent from a node owning a candidate cell, eNBs owning ES probing capable or

39、iginal cell(s) indicate its (their) presence to UEs for a period of time which last up to the Minimum Activation Time (see TS 36.300 10 section 22.4.4.2) . An ES probing cell prevents idle mode UEs from camping on the cell and prevents incoming handovers to the same cell. The results of these measur

40、ements are used to determine whether the cell has UEs within its reach and thus could take over load by going into the notEnergySaving state.g3g3compensatingForEnergySaving state: in an off-peak traffic situation, a network element is remaining powered on, e.g. taking over the coverage areas of neig

41、hbor base station in energySaving state. ES activation: the procedure to switch off a cell or network element or restrict the usage of physical resources for energy saving purposes. As a result, a specific network element transitions is in energySaving state. ES compensation: the procedure to change

42、 a cells or network elements configuration to remain powered on for compensating energy saving activation on other cells or network elements, e.g. by increasing a base stations coverage area. As a result, the network element is in compensatingForEnergySaving state. ES deactivation: the procedure to

43、switch on a cell ornetwork element or resume the usage of physical resources which had been ES activated before. As a result, a specific network element is in notEnergySaving state. Enable ES: ES (including ES activation/compensation/deactivation, related computations etc.) is allowed to be performe

44、d. Disable ES: ES is prohibited to be performed. When ES is disabled, subject cells or NEs are in notEnergySaving state. Candidate cell: candidate cell is a cell which can provide coverage when the original cell goes into energySaving state. 3.3 Abbreviations For the purposes of the present document

46、 version 14.0.0 Release 144 Concepts and Backgrounds 4.1.0 Introduction Protecting the environment and combating climate change are challenges that we face today. In the telecom environment, as energy prices increase, there is added incentive for Network Operators to look for means to reduce energy

47、costs. OAM of mobile networks can contribute to energy saving by allowing the operator to set policies to minimize consumption of energy, while maintaining coverage, capacity and quality of service. The permitted impact on coverage, capacity and quality of service is determined by operators policy.

48、When a cell is in energy savings state it may need neighbouring cells to pick up the load. However a cell in energySaving state cannot cause coverage holes or create undue load on the surrounding cells. All traffic on that cell is expected to be drained to other overlaid/umbrella cells before any ce

49、lls moves to energySaving state. A cell in energySaving state is not considered a cell outage or a fault condition. No alarms should be raised to the IRPManager for any condition that is a consequence of a NE moving into energySaving state In addition, the use of the renewable energy sources (e.g. wind, solar energy) should be encouraged in mobile networks. The following ESM concepts can apply to different RATs, e.g. UMTS and LTE. Nevertheless some of these ESM concepts may be limited to specific RATs and network elements, and s
