Overview

2.1 Introduction To construct a network with a large capacity, wide coverage, and good performance, an operator needs to deploy a large number of BTS sites. Generally, the power consumption of BTS equipment and air-conditioning equipment takes more than 90% of the power consumption of the radio access network. In addition to paying a high cost for power, the operator needs to conform to the social responsibility of energy saving, emission reduction, and environment protection. By introducing the solution of intelligent power consumption decrease to the BSS equipment and adopting the advanced power control algorithm, Huawei can help the operator solve this problem. Intelligent power consumption decrease refers to the solution of decreasing power consumption of the BTS or even a coverage area through hardware or software without deteriorating network performance and BTS hardware performance. The BTS site power consumption includes BTS power consumption and air-conditioner power consumption, where, based on the BTS power consumption, the air conditioner is selected. Therefore, intelligent power consumption decrease aims to decrease the BTS power consumption. The BTS power consumption includes cabinet power consumption and TRX power consumption, as shown in Figure 2-1.

2 Overview

Figure 2-1 BTS3900 power consumption

NOTE

The power consumption of other BTSs is similar to the BTS3900 power consumption.

l

Cabinet power consumption The cabinet power consumption, a small part of the BTS power consumption, is generated by the TRX supporting system and basic site control and transmission equipment.

l

TRX power consumption The TRX power consumption constitutes a primary part of the BTS power consumption. The power consumption of TRXs is related to factors such as number of configured TRXs, traffic volume, output power, and working mode. The TRX power consumption includes: – Dynamic power consumption of the power amplifier: power consumed by the power amplifier for carrying services. – Static power consumption of the power amplifier: power consumed by the static current that ensures the normal operation of the power amplifier. Dynamic power consumption of the power amplifier and static power consumption of the power amplifier constitute the power consumption of the power amplifier. – Baseband power consumption: power consumed by Digital Signal Processor (DSP), Field Programmable Gate Array (FPGA), and Central Processing Unit (CPU). – Power consumption of the Radio Frequency RF signal: power consumed by the digital intermediate frequency (IF) circuit, Digital-to-Analog/Analog-to-Digital (DA/AD) circuit, and low-power RF signal circuit.

Through intelligent power consumption decrease, power consumption of the power amplifier, baseband power consumption, and power consumption of the RF signal are decreased. Therefore, the BTS power consumption is decreased. The technologies involved in the intelligent power consumption decrease are TRX power amplifier intelligent shutdown, TRX power amplifier intelligent shutdown on the timeslot level, intelligent combiner bypass, intelligent adjustment of TRX working voltage, channel allocation algorithms concerning power consumption decrease, Power Supply Unit (PSU) smart control, Discontinuous transmission (DTX), power control, power optimization based on channel type, enhanced BCCH power consumption optimization, active backup power control, and dynamic cell power off.

2 Overview

Intelligent power consumption decrease can save energy, reduce emission, and save capital expenditure (CAPEX) by decreasing the BTS power consumption. In the case of the BTSs with storage battery and other power backups, intelligent power consumption decrease can prolong the serving time of the storage battery and shorten the serving time of the generator. Intelligent power consumption decrease can also prolong the serving time of cells and reduce the number of storage batteries, saving CAPEX.

3 TRX Power Amplifier Intelligent Shutdown

TRX Power Amplifier Intelligent Shutdown The TRX power consumption is mainly generated by the power amplifier. When there is no traffic, only static power consumption of the power amplifier is generated, that is, the dynamic power consumption is zero. When there is traffic, dynamic power consumption is generated. The dynamic power consumption increases with the TRX output power. Generally, a cell is not always in the busy state. When the TRX Power Amplifier Intelligent Shutdown feature is enabled, only some TRXs carry the traffic in a cell, and the power amplifiers of the TRXs not carrying traffic are shut down. That is, the power amplifiers of the TRXs whose dynamic power consumption is zero are shut down. Therefore, the BTS power consumption is reduced. The TRX Power Amplifier Intelligent Shutdown feature has no adverse effect on network quality. If the MS is assigned with channels of TRXs whose power amplifiers are shut down, however, the MS takes a longer time to access the network, because switching on the power amplifiers of the TRXs is time consuming. To minimize the impact of TRX power amplifier intelligent shutdown on the network quality, the parameters StartTimeTACloseTrxPA(BSC6900,BSC6910) and EndTimeTACloseTrxPA (BSC6900,BSC6910) can be specified at the BSC. The traffic volume on weekends and holidays are higher than on weekdays, and the busy hours in weekends and holidays are more than weekdays. You can set StartMonthDSTPA(BSC6900,BSC6910) and StartDayDSTPA (BSC6900,BSC6910) at the BSC so that the BSC disables the TRX Power Amplifier Intelligent Shutdown feature from the specified date. You can also set EndMonthDSTPA (BSC6900,BSC6910) and EndDayDSTPA(BSC6900,BSC6910) so that the TRX Power Amplifier Intelligent Shutdown feature is enabled again from the specified date. The TRX whose power amplifiers can be shut down must meet the following conditions: l

The TRX works normally.

l

The maximum operation interval of the TRX is greater than ProtectTimeTrxPowerOn (BSC6900,BSC6910).

l

After the TRX is shut down, an idle standalone dedicated control channel (SDCCH) is still available for use in this cell.

l

There is no packet traffic channel on the TRX.

l

No channel under conversion exists on the TRX.

l

The TRX does not carry the broadcast control channel (BCCH).

Issue 02 (2014-06-30)

If the TRX Power Amplifier Intelligent Shutdown feature is enabled in a cell, the BSC predicts the number of channels that the cell requires in the next one minute based on the history channel usage when the TRX Power Amplifier Intelligent Shutdown feature is not prohibited. If the number of channels that the cell requires is smaller than that of the remaining channels after a TRX is shut down, and the number of the remaining channels is greater than the value of ReservedIdleCh(BSC6900,BSC6910), the BSC attempts to shut down a TRX having no PDCH and whose channel usage is the lowest. l

If no channels carried by the TRX are seized, the BSC shuts down the TRX.

l

If TCHs carried by the TRX are seized, the BSC hands over the services on the TRX to other TRXs, and then shuts down the TRX.

l

If SDCCHs carried by the TRX are seized, the BSC does not shut down the TRX until the SDCCHs are released.

The BSC preferentially allocates channels carried on operating TRXs to the MS. If there is no channel available carried by the operating TRX in the cell, the BSC allocates channels carried by the TRX that is shut down to the MS. The BSC notifies the BTS to switch on the power amplifier of the TRX, and then activates the channels carried on the TRX and allocates the channels carried by the TRX to the MS. To speed up channel assignment, the parameter ReservedIdleCh(BSC6900,BSC6910) is configured. When the number of idle TCHs is smaller than the value of this parameter, the BSC notifies the BTS to switch on a TRX that is shut down.

NOTICE It is recommended that ReservedIdleCh(BSC6900,BSC6910) be set to a value less than the number of available TCHs carried on the BCCH TRX. Baseband power consumption, RF signal power consumption, static TRX power consumption, and dynamic TRX power consumption constitute the power consumption of the TRX board. When the power amplifiers on a TRX board are all shut down, the BTS can shut down the lowpower RF signal circuit of the RF signals to further reduce the TRX power consumption. When any of the TRXs on the double-transceiver unit needs to be switched on, the BTS automatically switches on the RF signals. The TRX Power Amplifier Intelligent Shutdown feature is a prerequisite for TRX low-power signal intelligent shutdown. That is, the TRX lowpower signals are shut down only after the power amplifiers of the TRX are shut down. You are advised to enable the low-power signal intelligent shutdown feature when the traffic volume is low, for example, at night. The BSC can control TRX power amplifier intelligent shutdown only when the parameter BSCDynSwitchTrxPAAllow(BSC6900,BSC6910) on the BSC level, the parameter DYNOpenTrxPower(BSC6900,BSC6910) on the cell level, and the parameter CPS (BSC6900,BSC6910) on the TRX level are all set to YES(Yes). In a cell enabled with baseband FH or hybrid FH, if all the TRXs in a same baseband FH group meet the requirements for the TRX Power Amplifier Intelligent Shutdown feature, then all the TRXs in the baseband FH can be shut down. When the TRXs are powered on again, the TRXs in the same baseband FH group need to be powered on at the same time. l

Issue 02 (2014-06-30)

When the BCCH TRX participates in baseband FH, the TRXs in the cell cannot be shut down. Therefore, the TRX Power Amplifier Intelligent Shutdown feature cannot be used. Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

l


When the BCCH TRX does not participate in baseband FH and all the TRXs (excluding the BCCH TRX) in the cell are idle, the TRXs can be shut down.

Generally, the TRX Power Amplifier Intelligent Shutdown feature is used together with channel allocation optimization. The channels on the BCCH TRX are preferentially assigned so that the utilization of the non-BCCH TRX channels is decreased and the overall power consumption of the BTS is reduced. In addition, the BTS allocates channels based on the priorities of TRXs. Channels on the TRXs with high priorities are preferentially assigned to MSs. In this way, the BSC centralizes busy channels into a few TRXs so that as many idle TRXs as possible can be shut down.

GSM BSS Intelligent Power Consumption Decrease Feature Parameter 4 TRX Power Amplifier Intelligent Shutdown on Timeslot Level Description

4

TRX Power Amplifier Intelligent Shutdown on Timeslot Level The optimized double-transceiver unit supports separate control of two power amplifiers. Therefore, the TRX Power Amplifier Intelligent Shutdown on the Timeslot Level feature is supported and the power consumption of the power amplifier on the timeslot level is zero. There are eight timeslots in a TRX. If only one timeslot has traffic and the other seven timeslots are idle, the power amplifier is working only in the timeslot with the traffic, and is shut down in the other seven timeslots. The power amplifier on the double-transceiver unit is switched on or shut down during the time on the timeslot level. In this manner, when timeslots are idle, the power consumption generated by the power amplifier can be reduced during the fixture of offset voltage in the linear area. TRX power amplifier intelligent shutdown on the timeslot level does not affect channel assignment and traffic. Therefore, it has no adverse effect on network quality. The power supply of the power amplifier is controlled inside the BTS, and the power amplifier can be switched on or shut down during the normal traffic processing procedure. This is achieved by the Huawei technology of high-speed power supply control of power amplifier, where the power amplifier can be switched on or shut down in a very short time (close to 0s). The power amplifier is a field-effect transistor. One of the main factors that affect the life cycle of the field-effect transistor is the high temperature caused by high electrical current. When the power amplifier is shut down, there is no current and the accumulated heat is released. Therefore, when intelligent power amplifier shutdown on the timeslot level is enabled, the lifetime of the power amplifier is preserved. Compared with the TRX Power Amplifier Intelligent Shutdown feature, the TRX Power Amplifier Intelligent Shutdown on the Timeslot Level feature enables the switch on and shutdown of the power amplifier on the timeslot level. When there are idle timeslots, the TRX that cannot be shut down by using the TRX Power Amplifier Intelligent Shutdown feature can be shut down using the TRX Power Amplifier Intelligent Shut Down on the Timeslot Level feature. Therefore, the power consumption of power amplifier can be reduced to the greatest extent. The TRX Power Amplifier Intelligent Shutdown on the Timeslot Level feature is controlled by TSSHTDOWNEN(BSC6900,BSC6910), and can be applied to only the double-transceiver unit.

5 Intelligent Combiner Bypass


Intelligent Combiner Bypass (ICB) applies only to double-transceiver units. When the nonBCCH TRX is idle, the BCCH TRX is in ICB mode with a capacity of one TRX. The lowest voltage is used by power amplifier on the BCCH TRX, and the output power of a single power amplifier on the BCCH TRX is 15 W/10 W. After Power Burst Technology (PBT) is used on the BCCH TRX, the output power at the top of the cabinet of the BCCH TRX is the same as that of a single power amplifier, that is, 60 W/ 40 W. Take an S4 cell for example. To meet the coverage requirement of the cell, the output power on the TRX port must be 30 W. Generally, the output power of the TRX is 60 W. After the combination, the output power of both TRXs is 30 W so that the coverage requirement of the cell is met. When the traffic volume is lower than that in S2 cell, the output power of each TRX can be reduced to 15 W if the PBT mode is used, so that the combination output power remains 30 W, as shown in Figure 5-1. In this case, the cell capacity is reduced to S2. The TRX power, however, decreases from 60 W to 15 W. As a result, the power consumption of the TRX is greatly reduced and the power consumption of the BTS is lowered.

5 Intelligent Combiner Bypass

Figure 5-1 ICB principle

Intelligent combiner bypass is controlled by the ICBALLOW(BSC6900,BSC6910) parameter. If this parameter is set to Yes, the intelligent combiner bypass feature is enabled. Enabling the ICB feature saves energy only if either of the following conditions is met: l

The output power of the TRX is 60 W and the static power level is 0 or 1.

l

The output power of the TRX is 40 W and the static power level is 0.

To enable the intelligent combiner bypass feature, you should set the OPTL (BSC6900,BSC6910) of the TRX that is on the same double-transceiver unit as the BCCH TRX to a low level. This ensures that the BCCH TRX is selected preferentially to enter the ICB mode when the cell has spare capacity. In this manner, power consumption is decreased. NOTE

The OPTL(BSC6900,BSC6910) parameter is used together with TRXPRIALLOW (BSC6900,BSC6910). The channel can be assigned based on the TRX priority only when TRXPRIALLOW (BSC6900,BSC6910) is set to Yes.

6 Channel Allocation Algorithms Concerning Power Consumption Decrease

Channel Allocation Algorithms Concerning Power Consumption Decrease The BTS power consumption can be decreased through proper channel allocation. The channel allocation algorithms concerning intelligent power consumption decrease include preferential allocation of channels on the BCCH TRX and preferential allocation of channels on the TRX with a good power-saving performance.

Preferential Allocation of Channels on the BCCH TRX Regardless of whether channels on the BCCH TRX are seized, signals are transmitted with full power. When channels carried on the BCCH TRX are seized, normal bursts are transmitted; when channels carried on the BCCH TRX are idle, dummy bursts are transmitted. TRX power amplifier intelligent shutdown on the timeslot level, power control, and DTX cannot be applied to BCCH TRX. With the introduction of preferential allocation of channels on the BCCH TRX, the BSC preferentially allocates channels on the BCCH TRX to the MS to reduce the utilization rate of channels carried by non-BCCH TRXs so that intelligent power consumption decrease can be applied to the non-BCCH TRXs. Preferential allocation of channels on the BCCH TRX is controlled by OPTL (BSC6900,BSC6910). The higher the OPTL(BSC6900,BSC6910), the lower the priority of channel allocation. Therefore, preferential allocation of channels on the BCCH TRX can be achieved by raising OPTL(BSC6900,BSC6910) of the non-BCCH TRX.

Preferential Allocation of Channels on the TRX with a Good Power-Saving Performance With different power-saving performance of various chips, TRXs produced at different periods and of different types have different power-saving capabilities. When there are TRXs with different power-saving performance in a cell, you can preferentially use the TRXs with good power-saving performance and apply power-saving technology to the TRXs with poor powersaving performance to decrease the BTS power consumption. When a TRX is powered on, the TRX reports its power-saving performance to the BSC and then the BSC preferentially allocates the channels on the TRXs with good power-saving performance to the MS.

7 Power Optimization Based on Channel Type

Power Optimization Based on Channel Type This chapter describes the GBFD-111606 Power Optimization Based on Channel Type feature. Different channels use different modulation modes. After the Enhanced General Packet Radio Service (EGPRS) feature is introduced to the GSM network, the 8PSK modulation mode is added to the GMSK modulation mode. With the same output power, a higher voltage is required by the TRX power amplifiers in 8PSK modulation mode than in GMSK modulation mode. Power optimization based on channel type refers to the technology that the voltage is provided for TRX power amplifiers based on different modulation modes of channels so that the BTS power consumption can be decreased. If the channels on a TRX are all TCHs, the TRX works in GMSK modulation mode, and the TRX power amplifiers are provided with a voltage in accordance with the GMSK modulation mode; if there are static or dynamic PDCHs on the TRX, the TRX works in 8PSK modulation mode, and the TRX power amplifiers are provided with a voltage in accordance with the 8PSK modulation mode, as shown in Figure 7-1. Figure 7-1 Principle of power optimization based on channel type

7 Power Optimization Based on Channel Type

NOTE

When there are PDCHs on the TRX, regardless of whether they are static or dynamic, the TRX power amplifiers should be provided with a voltage in accordance with the 8PSK modulation mode. That is, the power optimization based on channel type is not on timeslot level.

Power optimization based on channel type is controlled by PDCHPWRSAVEN (BSC6900,BSC6910). Power optimization based on channel type is applicable to double-transceivers. NOTE

To enable power optimization based on channel type, ensure that the following conditions are met: l The power amplifiers on TRXs support working voltage adjustment. l BTSadjust(BSC6900,BSC6910) is set to YES(Yes).

8 Active Backup Power Control


8.1 Overview When the mains supply is cut off, the BTS uses the storage battery as a backup power supply source. To prolong the battery discharge time, the system reduces the BTS power consumption by shutting down some TRXs or reducing the maximum TRX output power. After the mains supply recovers, the system activates all the TRXs and restores the maximum transmit power of TRXs. The Active Backup Power Control feature applies to centralized power supply scenarios. In distributed power supply scenarios, if Active Backup Power Control is enabled and the power supply of an RRU is faulty, the BSC may reduce the power of all the RRUs in the cell. As a result, ongoing services are affected. Figure 8-1 shows the BTS3900 (–48 V DC) cabinet with centralized power supply. Figure 8-1 BTS3900 (–48 V DC) cabinet with centralized power supply

NOTE

l Centralized power supply: The power supply devices of main BTS equipment (BBU and RFU/RRU modules) are deployed together, and all the devices report power alarms when the mains supply becomes unavailable. l Distributed power supply: The power supply devices of main BTS equipment (BBU and RFU/RRU modules) are not deployed together, and some devices may not report power alarms when the mains supply becomes unavailable.

When the mains supply for the BTS is cut off, batteries are used to supply power for the BTS. After the period specified by PWROFFPROTECTSTARTTIME (BSC6900,BSC6910,eGBTS) expires, the system shuts down some TRXs based on the battery power reduction algorithm, and gradually reduces the transmit power of the remaining TRXs with a certain step until the entire BTS is powered off. This function is enabled with BAKPWRSAVMETHOD(BSC6900,BSC6910,eGBTS) set to BYPWR(Reduce Backup Power). Two critical actions are involved in battery power reduction: shutting down some TRXs and reducing transmit power of the remaining TRXs gradually. l

Shutting down some TRXs The system shuts down all the non-BCCH TRXs for which the SDFLAG (BSC6900,BSC6910) parameter is set to ENABLE(Enable) on the BTS. The system also shuts down the BCCH TRX when the BTSPOWEROFFLOCKBCCH (BSC6900,BSC6910) parameter is set to YES(Yes).

l

Reducing transmit power of the remaining TRXs gradually The system gradually reduces the maximum transmit power of all the working TRXs on the BTS. – For a GBTS, the system reduces the transmit power of all the working TRXs at an interval specified by DROPPWRINTERVAL(BSC6900,BSC6910). The DROPPWRSTEP(BSC6900,BSC6910) parameter specifies the amount of power reduced at a time. The MAXDROPPWRTHRESHOLD(BSC6900,BSC6910) parameter specifies the maximum power reduction amount. – For an eGBTS, the system reduces the transmit power of all the working TRXs at an interval specified by DROPPWRINTERVAL.

The Active Backup Power Control feature supports three battery power reduction policies based on the cell coverage, cell capacity, and backup power supply duration: BYCOVER(Cover Priority), BYCAP(Capability Priority), and BYSAVING(Saving Priority), which can be specified using the BAKPWRSAVPOLICY(BSC6900,BSC6910,eGBTS) parameter.

8.2 Battery Power Reduction Policies BYCOVER(Cover Priority) If BAKPWRSAVPOLICY(BSC6900,BSC6910,eGBTS) is set to BYCOVER(Cover Priority), the system shuts down some TRXs and then reduces the transmit power of the remaining TRXs gradually. The procedure is as follows: Issue 02 (2014-06-30)

1.

After the period specified by PWROFFPROTECTSTARTTIME (BSC6900,BSC6910,eGBTS) expires following the cutoff of the mains supply for the BTS, the system shuts down some TRXs.

2.

The system starts reducing the transmit power of the remaining TRXs after a certain period of time. This period is specified by DROPPWRSTARTTIME(BSC6900,BSC6910) for a GBTS or by SECPHRASESTARTTIME for an eGBTS.

BYCAP(Capability Priority) If BAKPWRSAVPOLICY(BSC6900,BSC6910,eGBTS) is set to BYCAP(Capability Priority), the system gradually reduces the transmit power of all TRXs and then shut down some of the TRXs. The procedure is as follows: 1.

After the period specified by PWROFFPROTECTSTARTTIME (BSC6900,BSC6910,eGBTS) expires following the cutoff of the mains supply for the BTS, the system gradually reduces the transmit power of all TRXs.

2.

The system shuts down some TRXs after a certain period of time. This period is specified by SHUTDOWNTRXSTARTTIME(BSC6900,BSC6910) for a GBTS or by SECPHRASESTARTTIME for an eGBTS.

BYSAVING(Saving Priority) If BAKPWRSAVPOLICY(BSC6900,BSC6910,eGBTS) is set to BYSAVING(Saving Priority), the system shuts down some TRXs and at the same time reduces the transmit power of the remaining TRXs gradually. The system performs these actions after the period specified by PWROFFPROTECTSTARTTIME(BSC6900,BSC6910,eGBTS) expires following the cutoff of the mains supply for the BTS.

9 GSM and UMTS Intelligent Shutdown Based on RAT Priority

GSM and UMTS Intelligent Shutdown Based on RAT Priority With the increasing GSM/UMTS network convergence, GSM TRXs, UMTS TRXs, and GSM +UMTS dual-mode TRXs are used in a site or even in a BTS cabinet (dual-mode in a BTS cabinet). Moreover, when a GSM+UMTS dual-mode TRX is used, the GSM network and UMTS network share a TRX (GSM+UMTS dual-mode in a TRX). This feature is applied to the scenario where GSM TRXs and UMTS TRXs, or GSM+UMTS dual-mode TRXs, are in the same BTS cabinet, and uses the same BBU and groups of storage batteries. If the mains power supply fails and therefore the base station is provided with power by storage batteries, operators can automatically shut down GSM TRXs (or UMTS TRXs) or stop providing GSM services (or UMTS services) by using the function of Active Backup Power Control according to the priorities of the GSM network and UMTS network. In this manner, the UMTS network (or GSM network) has more backup power, and therefore provides services for a longer time. By using this feature, operators can shut down TRXs or stop providing services according to the requirements for GSM/UMTS network coverage. (GBFD-511206 GSM and UMTS Intelligent Shutdown Based on RAT Priority) This feature is implemented by setting PWROFFPROTECTSTARTTIME (BSC6900,BSC6910) for both GSM and UMTS. If GSM services have a higher priority than the UMTS services when the mains power supply fails, PWROFFPROTECTSTARTTIME (BSC6900,BSC6910) concerning the UMTS network is set to a small value. In this manner, the UMTS TRXs can be powered off rapidly and therefore the lifespan of the GSM backup power is prolonged. Similarly, if UMTS services have a higher priority than the GSM services when the mains power supply fails, PWROFFPROTECTSTARTTIME (BSC6900,BSC6910) concerning the GSM network is set to a small value. In this manner, the GSM TRXs can be powered off rapidly and therefore the lifespan of the UMTS backup power is prolonged. The following GSM+UMTS dual-mode co-cabinet BTSs or BTS groups support this feature: l

10 Weather Adaptive Power Management


This chapter describes the GBFD-111613 Weather Adaptive Power Management feature.

Issue 02 (2014-06-30)


22



10.1 Overview As operators pay more attention to energy saving and power consumption reduction, regenerative energy such as solar energy, wind energy, and biological mass energy have been widely applied to the emerging wireless sites. To configure regenerative energy sources on site in an accurate and cost-effective manner, you must ensure that the generation capacity of the regenerative energy exactly matches the energy consumption on site. The quality of wireless services is primarily defined by the coverage of BTS and the downlink output power. The serving time of wireless services is represented by the duration of service provision and the probability of energy exhaustion on site. Weather adaptive power management is to balance the wireless service quality and the serving time. Based on the estimation of regenerative energy generation and the energy consumption on site, this feature dynamically determines the energy consumption behavior, serving time, and service quality on the site. This feature helps minimize the possibility of the site running out of power, increase the reliability of energy provision, prolong the serving time of the site, and reduce or optimize the configuration costs of regenerative energy, when ensuring the desirable service quality. Weather adaptive power management determines the proper volume of energy consumption based on the available energy sources (the electric power is generated by the solar battery, not by the algorithm or storage battery). The general principle is to keep balance between energy consumption and generation, to prevent power failures and energy wastes at the same time. If the ratio of energy consumption at a level higher than the average energy generation capacity increases, the ratio of energy consumption at a level lower than the average generation capacity increases either, or the probability of power failures increases. The algorithm allows customers to choose from the radical, balanced, and conservative energy consumption modes. Currently, weather adaptive power management is applicable to sites using combined energy of solar energy and battery. The feature will be applied to sites using regenerative energy such as wind energy and biological mass energy later.

10.2 Principles The weather adaptive management algorithm works cyclically. Its working principle is as follows: At a certain moment, the algorithm calculates the allowed power consumption of the BTS in an algorithm period based on the obtained remaining capacity of the storage battery, the calculated power generation capacity, and the local average power consumption value and power consumption trend. After the BTS runs for an algorithm period at the corresponding power level, the algorithm is called again to calculate the allowed power consumption of the BTS in the second period based on the obtained remaining capacity of the storage battery, the calculated power generation capacity, and the local average power consumption value and power consumption trend. The algorithm is called again and again at the interval to calculate and the power consumption of the BTS, and therefore the power consumption is controlled. Issue 02 (2014-06-30)

Figure 10-1 Working principles

Weather adaptive power management is composed of the following functional modules: l

Power generation capacity estimation module The module estimates the generation capacity of the solar panel based on the total radiation strength on the horizontal surface provided by the customer or the weather forecast (sunny, cloudy, or rainy).

l

Correction module for power generation capacity estimation The module corrects the errors of the total radiation strength on the horizontal surface provided by the customer or the weather forecast, and the error between the estimated and actual power generation capacity caused by environment changes.

l

BTS power consumption estimation module The module estimates the power consumption of the BTS based on the BTS type, configuration, and energy saving measures.

The module corrects the power consumption estimation based on the actual power consumption values that are specific according to different configurations and traffic loads. l

Power consumption control module The module calculates the planned output power of the BTS based on the currently available capacity of the storage battery, currently estimated power generation capacity, energy consumption trend, estimation period, current input power, and the high (medium or low) capacity threshold of the storage battery. The U2000 supports weather-adaptive energy conservation operations for a GBTS. The operations include creating, modifying, starting, deleting, and viewing a task. After a user creates and starts a weather-adaptive energy conservation task on the U2000, the U2000 estimates the amount of electricity that can be generated by the GBTS solar panels based on weather data. Then, the U2000 periodically generates the power levels available to the GBTS based on information such as the generated amount of electricity, remaining battery electricity, and GBTS power consumption.

11 Intelligent Power Measurement

Intelligent Power Measurement

With Intelligent Power Measurement, a BTS measures its power consumption and reports it to the U2000 so that operators can know the BTS power consumption. This feature enables a BTS to calculate its power consumption by means of direct measurement or accumulation. l

Direct Measurement Only a BTS configured with the PMU supports direct measurement. In direct measurement, the PMU measures the current and voltage, calculates the overall BTS power consumption, and reports the measurement results to the main control board. The main control board periodically reports the BTS power consumption to the U2000. Direct measurement results have an error margin of around 5%.

l

Accumulation Accumulation applies to all BTSs. In accumulation, the BTS searches a power consumption table for typical power consumption of each configured board. The BTS then adds up the power consumption values to obtain the overall BTS power consumption. The power consumption of an RF board equals the sum of the products of the current and voltage on all the power amplifiers of the RF unit. Accumulation results have an error margin of around 10%. In a multimode base station, each mode reports its own power consumption (including power consumed by non-RF boards and RF boards) to the U2000. The U2000 then adds up the power consumption reported from each mode to obtain the overall power consumption of the multimode base station.

For a GBTS, the SPRECM(BSC6900,BSC6910) parameter determines whether to enable Intelligent Power Measurement. For an eGBTS, no parameter determines whether to enable Intelligent Power Measurement. A BTS can report either AC or DC power consumption to the U2000. To determine whether a BTS reports AC or DC power consumption, operators can specify the ECMP (BSC6900,BSC6910) parameter for a GBTS or the MP parameter for an eGBTS. The power system of a BTS configured with a PMU converts the AC power supply into the DC power that the BTS can use. Because power loss occurs during power conversion, the value of AC power consumption is different from that of DC power consumption. To learn how much power consumption is lowered for a BTS, enable the BTS to report AC power consumption.

14.7.4 Activation Observation Observing the gains brought by Multi-Carrier Intelligent Voltage Regulation is difficult on live networks because traffic loads change in various ways at long intervals and the power consumption is likely to fluctuate. Therefore, select site models in several different areas, for example, heavily-populated areas, urban areas, suburbs, and countryside, to observe the feature gains in a laboratory. You can use either an external instrument or the intelligent power consumption detection function. You are advised to monitor the performance on 2 days with similar traffic volume. NOTE

l Ensure that batteries are fully charged because battery charging affects power consumption. l The power consumption measured by using the intelligent power consumption detection function is a little different from the actual power consumption. In addition, this function has special requirements for the power system. Therefore, use this function based on site conditions. For details about the intelligent power consumption detection function, see 11 Intelligent Power Measurement.

Using an External Instrument Step 1 Do as follows without enabling Multi-Carrier Intelligent Voltage Regulation: 1.

Issue 02 (2014-06-30)

Use a current measurement instrument and a voltage measurement instrument to continuously measure the current and voltage of a multi-carrier RF module, respectively. Measure the current and voltage for a 24-hour period at a fixed interval, such as every 5 minutes. Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

2.


Record the measured values. Use the average current and voltage measured in an hour as the current and voltage values for the hour, and then calculate the power consumption in each hour by multiplying the average current and voltage.

Step 2 Enable Multi-Carrier Intelligent Voltage Regulation and then repeat the preceding operations to obtain the power consumption in a day. Step 3 Compare the power consumption before and after this feature is activated. Expected result: The power consumption decreases after this feature is activated. ----End

Using the Intelligent Power Consumption Detection Function Step 1 On the BSC LMT, run the SET BTSOTHPARA command with Whether to Enable Energy Consumption Measurement set to YES(YES) and Energy Consumption Measurement Point set to DC(DC). Step 2 Subscribe to the counters listed in Table 14-21 on the U2000 to observe the traffic statistics in the week before and after Multi-Carrier Intelligent Voltage Regulation is activated.

14.8.3 Activation Observation Step 1 Perform the following steps before activating this feature: 1.

Cut off the mains supply for the GBTS on the local side. The GBTS generates ALM-25622 Mains Input Out of Range or the mains supply cutoff alarm, and starts power supply by the battery.

2.

Power off the GBTS after ALM-21807 OML Fault is generated.

3.

Calculate the interval from when the GBTS generates ALM-25622 Mains Input Out of Range or the mains supply cutoff alarm to when the GBTS generates ALM-21807 OML Fault.

Step 2 Perform the preceding steps in the same time period on different days after activating the feature. Step 3 Compare the interval calculated in 1.3 performed before and after activating the feature. Expected result: The interval calculated prolongs after the feature is activated. This indicates that the Active Backup Power Control feature has taken effect. ----End

14.8.4 Deactivation Using MML Commands On the BSC LMT, run the SET BTSBAKPWR command with Backup Power Saving Method set to BYTRX(Turn off TRX).

SET GCELLOTHE XT

GBFD-111602


Meaning:This parameter specifies the number of idle channels that should be reserved on a cell after the TRX is shut down. When the number of idle channels on a cell is less than or equal to this threshold, the BSC enables a TRX. This parameter is used to prevent the impact enabling or disabling delay on the efficiency of channel assignment on the cell that is enabled with the TRX Intelligent Shutdown feature. The value of this parameter represents the number of TCHFs and is used after being converted to the number of TCHHs. For example, if this parameter is set to 1, two idle TCHHs are reserved for the cell. GUI Value Range:0~16
