A term defined i
35、n 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 V13.0.0 (2016-02)63GPP TS 32.551 version 13.0.0 Release 13 NM-Ce
36、ntralized 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 executed at the Network Element level. notEnergySaving stat
37、e: 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 other ways, whereas the cell or network element is still
38、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 original cell(s) indicate its (their) presence to UEs fo
39、r 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 measurements are used to determine whether the cell has UEs
40、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 neighbor base station in energySaving state. ES activation
41、: 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 a cell“s or network element“s configuration to remain
42、 powered on for compensating energy saving activation on other cells or network elements, e.g. by increasing a base station“s coverage area. As a result, the network element is in compensatingForEnergySaving state. ES deactivation: the procedure to switch on a cell ornetwork element or resume the us
43、age 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 performed. Disable ES: ES is prohibited to be performed. Wh
44、en 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, the abbreviations given in TR 21.905 1 and the fo

46、s 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 costs. OAM of mobile networks can contribute to ene
47、rgy 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 operator“s policy. When a cell is in energy savings state it may need
48、 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 cells moves to energySaving state. A cell in energyS
49、aving 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 specific solutions may be required for them. 4.1.1 F
