Description

一种电池控制方法、装置及设备
本申请要求于2021年09月29日提交中国国家知识产权局、申请号为202111155643.X、发明名称为“一种电池控制方法、装置及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种电池控制方法、装置及设备。
背景技术
基站(Base Station)是通信系统中的重要组成部分，可以用于将手机等终端设备接入网络。基站主要以市电作为电力来源。因此，当市电出现停电时，基站无法继续工作，也就无法为终端设备提供接入服务。
因此，为了保证基站在停电条件下的正常工作，可以在基站中设置备用电池。这样，当市电正常供电的情况下，基站采用市电作为电力来源。在市电出现停电的情况下，基站可以采用备用电池作为电力来源，从而保证基站的正常工作。
但是，目前基站的备用电池仅在市电停电的情况下被使用，而备用电池本身寿命有限，导致基站的运营成本较高。
发明内容
本申请提供了一种电池控制方法、装置及设备，旨在降低基站的运营成本。
第一方面，本申请提供了一种电池控制方法，该方法可以用于对基站的备用电池进行控制。在基站的运营过程中，可以先对基站在未来的第一预设时间内可能承载的业务量进行预测，得到第一业务量。在确定第一业务量之后，可以根据对应关系确定基站承载第一业务量的业务所需的第一目标电量。即，第一目标电量为停电状态下维持基站在未来的第一预设时间内正常工作所需要的电量的最小值。接着，如果备用电池的剩余电量大于第一目标电量，说明可以利用备用电池实现错峰用电，降低基站的用电成本。那么在备用电池的剩余电量大于第一目标电量，且电力特征值满足第一条件的情况下，可以将基站的供电电源从市电切换到备用电池，从而在当前时刻避免采用成本较高的市电进行供电。这样，由于错峰配电的过程中备用电池的剩余电量大于第一目标电量，即使市电停电，备用电池中所储备的电能仍然可以支持基站持续工作第一预设时间。如此，在保证基站的备电充足的基础上，实现了错峰供电，降低了基站的运营成本。
在一些可能的实现中，对应关系可以包括业务量和功耗之间的对应关系，第一目标电量可以是根据基站可能的功耗确定的。具体地，在确定第一目标电量的过程中，可先根据第一业务量和对应关系，确定基站在未来的第一预设时间内可能的功耗变化趋势。接着，可以根据基站在第一预设时间内的功耗变化趋势，并结合时间确定第一目标电量。如此，通过确定基站在第一预设时间内各个时间段可能的功耗，得到的第一目标电量更加准确。
在一些可能的实现中，还可以根据电量预留策略对第一业务量进行修正，使得根据第一业务量计算出的第一目标电量更加接近基站实际的用电情况。其中，电量预留策略体现基站在停电状态下对业务的支持情况，例如可以指示基站在市电停电状态下拒绝支持部分业务。具体地，在确定功耗变化趋势之前，可以先根据第一业务量和电量预留策略确定第 二业务量。其中，第二业务量为停电状态下仍然被基站支持的业务在第一预设时间内产生的业务量，即停电状态下基站实际需要支持的业务量。在得到第二业务量之后，可以根据第二业务量和对应关系确定基站在第一预设时间内的功耗变化趋势。
在一些可能的实现中，电量预留策略可以包括第一电量预留策略，第一电量预留策略可以用于支持基站在市电停电的状态下拒绝支持第一业务。那么在计算第二业务量的过程中，可以先根据第一电量预留策略确定在未来的第一预设时间内，第一业务可能产生的业务量，得到第三业务量。接着利用第一业务量减去第三业务量，得到的差即为基站在停电状态下支持的业务在第一预设时间内产生的业务量，即第二业务量。
在一些可能的实现中，第一业务量可以是根据基站的历史工作情况得到的。具体地，可以根据历史业务量数据和当前时间，对基站在未来第一预设时间内的业务量进行预测，得到第一业务量。其中，历史业务量数据包括基站在过去的多个时间段内对业务的承载情况。如此，结合基站历史的工作情况，可以较为准确地确定基站在未来第一预设时间内可能产生的业务量。
在一些可能的实现中，随着备用电池为基站进行供电，备用电池的剩余电量会不断减小。如果备用电池的剩余电量不大于第一目标电量，说明备用电池所储备的电能可能无法继续支持基站在市电停电状态下继续工作第一预设时间。那么，在备用电池的剩余电量小于第一目标电量时，可以将基站的电源从备用电池切换到市电。
在一些可能的实现中，还可以进一步利用市电为备用电池充电。具体地，可以检测市电的电力特征值是否满足第二条件。如果电力特征值满足第二条件，说明采用市电进行供电的成本较低，那么可以采用市电为备用电池充电，补充备用电池为基站供电时消耗的电能。
在一些可能的实现中，市电可能发生停电。那么在市电停电之后，可以控制备用电池为基站供电，使得基站在市电停电状态下的继续工作，进而保障通信系统的正常运行。
在一些可能的实现中，在市电停电状态下，可以控制基站拒绝支持部分业务，以减少基站的功耗，从而延长基站的运营时间。具体地，基站可以获取备用电池的剩余电量，并判断备用电池的剩余电量是否大于第二目标电量。如果备用电池的剩余电量不大于第二目标电量，可以根据剩余电量确定预设控制策略，并根据预设控制策略关闭基站的第二业务。其中，预设控制策略用于指示基站在市电停电的状态下关闭第二业务，第二业务可以包括基站支持的任意一种或多种业务。如此，在市电停电且备用电池中的剩余电量较少的情况下，可以关闭基站所承载的部分业务，降低基站的功耗，以延长基站的使用时间。
在一些可能的实现中，预设控制策略可以随着备用电池的剩余电量改变。具体地，如果检测到备用电池的剩余电量不大于第三目标电量，可以根据剩余电量调整预设控制策略，从而进一步减少基站所承载的业务，延长基站的使用时间。其中第三目标电量小于第二目标电量。
在一些可能的实现中，第二业务可以包括第五代移动通信技术新无线(5th Generation Mobile Communication Technology New Radio，5G NR)业务。

具体实施方式
下面结合附图对传统技术和本申请实施例提供的电池控制方法进行介绍。
参见图1，该图为本申请实施例提供的基站的一种应用场景的示意图。在图1所示应用场景中，基站10分别与备用电池20和市电电网30连接。在市电正常供电的情况下，基站10可以从市电电网30获取电能进行工作。而在市电出现故障的情况下，市电电网30无法向基站10提供足够的电能。基站10可以将供电电源由市电电网30切换到备用电池20，采用备用电池作为能源进行工作。如此，即使发生市电停电，基站10也能够采用备用电池20进行供电，保证用户能够正常使用通话和上网等移动通信业务。
对于基站的备用电池，其只有在市电停电的情况下才会得到应用。但是备用电池的寿命大多有限，即使基站使用备用电池的次数较少，基站的备用电池仍然需要定期更换，而更换备用电池产生的费用无疑会增加基站的运营成本。也就是说，由于传统技术对基站的备用电池的利用率较低，导致基站的运营成本较高。
为了解决上述问题，本申请发明人经研究发现，部分地区的电价可能随着时间的变化而变化。每天的不同时段的电价可能不同。例如，每日19时至22时可能是用电的高峰期，那么为了限制用电，这些时间段的电价可能相对较高。而每日22时至7时的用电人数可能较少，这些时间段的电价可能相对较低。因此，如果能够利用基站的备用电池实现错峰用 电，在电价较高时利用备用电池供电，在电价较低时为备用电池进行充电，可以有效地降低基站的运营成本。
为此，本申请实施例提供了一种电池控制方法，可以根据基站的业务量和对应关系确定需要为市电停电预留的第一目标电量，并在剩余电量大于第一目标电量且用电成本较高的情况下改用备用电池作为电池基站的电力来源。这样，在保证基站在停电状态下的正常工作的基础上，提高了备用电池的利用率，通过错峰用电降低了基站的运营成本。
本申请实施例提供的电池控制方法可以应用于图1所示应用场景中的基站10。其中，基站10可以包括计算机等具有数据处理功能的设备，本申请实施例提供的电池控制方法可以由该具有数据处理功能的设备执行。可选地，本申请实施例提供的电池控制方法也可以由独立的控制设备执行，用于对基站的供电系统进行控制。
参见图2，该图为本申请实施例提供的电池控制方法的一种流程示意图，本申请实施例提供的电池控制方法可以包括如下步骤：
S201：确定第一业务量。
为了确保基站的备用电池能够在市电停电的情况下支持基站保持工作状态，在控制采用备用电池为基站供电之前，可以先确定基站可能产生的第一业务量。其中，第一业务量为基站在未来第一预设时间内可能产生的业务量。即，在未来的第一预设时间内，若保证通信系统的正常工作，基站需要承载第一业务量的业务。那么为了使得通信系统可以在市电停电的状态下继续正常工作，可以在备用电池中预留第一业务量对应的电量。这样，即使出现市电停电，备用电池中剩余的电量仍然能够支持基站承载第一业务量的业务，使得通信系统可以正常运行。
在一些可能的实现方式中，基站的工作情况可能随时间变化。例如，每天不同时间段基站承载的业务量可能不同，且不同日期同一时间段基站承载的业务量可能较为接近。例如，对于居民区附近的基站，工作日工作时间(例如9:00至下午16:00)的业务量可能相对较少，而休息日对应时间的业务量可能相对较多。
因此，在本申请实施例中，可以根据基站的历史工作情况确定第一业务量。具体地，可以先获取历史业务量数据，历史业务量数据包括基站在过去多个时间段内业务量的承载情况。接着，可以根据历史业务量数据和当前时间，对基站在未来第一预设时间内的业务量进行预测，得到第一业务量。例如，可以将基站在上一周同一天的同一时间段所承载的业务量作为第一业务量。
在一些其他可能的实现中，第一业务量也可能是根据基站的最大负载得到的。例如，可以将基站在单位时间内能够负载的最大业务量与第一预设时间的长度相乘，得到的结果为基站在第一预设时间内能够承载的最大业务量。为了确保基站在市电停电状态下的正常工作，可以将该最大业务量作为第一业务量。
S202：根据第一业务量和对应关系，确定第一目标电量。
在得到第一业务量之后，可以根据第一业务量和对应关系确定第一目标电量。其中，第一目标电量为基站支持第一业务量的业务所需要的电量，对应关系可以体现业务量和耗电量之间的对应关系。
业务量在时间上的分布不同，基站承载对应业务所需的电量可能也不同。也就是说，如果第一业务量集中在较短的时间间隔内出现，基站消耗的电量可能较多；如果第一业务量平均分布在第一预设时间中，基站消耗的电量可能较少。因此，为了提高第一目标电量计算的准确率，在一些可能的实现方式中，第一业务量可以包括在第一预设时间内多个时间间隔中基站的业务量，例如可以包括基站在未来一小时内每分钟所需承载的业务量。相应地，对应关系可以包括业务量和功耗之间的对应关系，表示基站在单位时间内，承载对应业务量需要消耗的功率。
如果第一预设时间包括多个时间间隔，第一业务量包括基站在每个时间间隔内的业务量，那么在确定第一目标电量的过程中，可以先根据第一业务量和对应关系，确定基站在多个时间间隔中每个时间间隔内的功耗，得到基站在第一预设时间内的功耗变化趋势。接着，可以根据时间和功耗变化趋势，确定基站在第一预设时间内的总功耗，得到第一目标电量。可选地，功耗变化趋势可以是时间坐标系下的功耗变化曲线，可以通过对功耗变化曲线进行积分的方式计算得到第一目标电量。
在本申请实施例中，对应关系可以是根据基站的历史工作数据得到的。具体地，可以预先收集基站在运营过程中产生的业务量和承载对应业务量时基站的功耗，并对业务量和功耗进行分析，确定基站的功耗与所承载的业务量之间的对应关系。例如，在一些可能的实现方式中，可以以一个自然周为一个数据采集周期。在确定对应关系的过程中，可以将基站最近一个周期或多个周期的业务数据与功耗数据相关联，对其进行统计学习，确定基站的业务量和之间的对应关系。
在一些可能的实现方式中，为了确保基站在停电状态下的正常工作，可以为备用电池预留更多的电量。那么在计算得到第一目标电量之后，可以根据电量预留的策略增加第一目标电量。
随着通信技术的发展，一台基站可能支持多类业务，而基站为不同的业务提供服务的功耗可能不同。例如，一台基站可能同时支持第五代移动通信技术(5th generation Mobile Communication Technology，5G)类业务、第四代移动通信技术(4th generation mobile communication technology，4G)类业务和第二代手机通信技术(2nd generation wireless telephone technology)类业务三类业务。而其中5G类业务的功耗最高，2G类业务的功耗最低。在市电停电后，可以控制基站拒绝支持部分业务，以延长基站的工作时间。
由于基站在市电停电后会拒绝支持部分业务，第一业务量可能与基站在停电后实际承载的业务量之间存在一定的差异。因此，在一些可能的实现方式中，可以先根据电量预留策略对第一业务量进行修正，得到第二业务量，再根据第二业务量计算第一目标电量。其中，电量预留策略是根据基站在停电状态下支持的业务情况得到的，体现基站在停电状态下支持何种业务，以及拒绝支持何种业务。关于电量预留策略的详细介绍可以参见图3对应实施例的介绍，这里不再赘述。
根据前文介绍可知，第一目标电量可以是根据基站在第一预设时间内的功耗变化趋势得到的。那么在计算第一目标电量之前，可以先根据第一业务量和电量预留策略确定第二业务量，再根据第二业务量计算基站在第一预设时间内的功耗变化趋势。其中，第二业务 量为基站在停电状态下支持的业务在第一预设时间内产生的业务量。也就是说，在计算第一目标电量的过程中，可以先根据电量预留策略确定基站在市电停电状态下支持的业务，再确定这部分业务在第一预设时间内的业务量(即第二业务量)，最后再根据第二业务量计算功耗变化趋势，通过功耗变化趋势确定第一目标电量。
在一些可能的实现方式中，电量预留策略可能用于指示基站在市电停电的状态下拒绝支持部分业务。在本申请实施例中，基站在市电停电状态下拒绝支持的业务被称为第一业务。可选地，第一业务可以包括耗电量较高的5G类业务，例如拒绝支持5G NR业务。那么在确定第二业务量时，可以先根据电量预留策略确定第一业务，并确定第一业务在第一预设时间内产生的第三业务量，再将第一业务量与第三业务量做差，得到第二业务量。
S203：响应于备用电池的剩余电量大于第一目标电量，且电力特征值满足第一条件，控制基站从市电切换至备用电池进行供电。
在计算得到第一目标电量之后，可以比较备用电池的剩余电量和第一目标电量之间的大小。如果备用电池的剩余电量小于第一目标电量，说明备用电池当前所储备的电能无法支持基站在市电停电状态下工作第一预设时长。在这种情况下利用备用电池进行错峰供电可能无法保证基站的正常工作。因此，可以控制基站继续以市电作为电力来源，并根据电力特征值进一步判断是否需要对备用电池进行充电。其中，电力特征值可以用于表征基站采用市电供电的成本。可选地，电力特征值可以是基站消耗单位电能(例如千瓦时)产生的费用等参数，即市电的单位电价。
如果备用电池的剩余电量大于第一目标电量，说明备用电池当前所储备的电能能够支持基站在市电停电的状态下工作第一预设时长，即备用电池能够支持基站进行错峰用电，那么可以进一步判断电力特征值是否满足第一条件。其中，第一条件用于指示基站采用市电供电的成本高于第一阈值。可选地，第一条件可以指市电的单位电价处于电价循环周期内的最高值，也可以指市电的单位电价高于电价循环周期内的平均。
在本申请实施例中，可以在从市电的供电单位处查询得到电力特征值随时间的变化情况，并将电力特征值随时间的变化情况存储到基站中。这样，在基站的运营过程中，可以根据时间确定当前时刻的电力特征值。在一些其他可能的实现方式中，可以通过联网查询的方式获取市电的实时电力特征值。
也就是说，在电力特征值满足第一条件的情况下，基站采用市电进行供电的成本较高，如果基站继续采用市电作为电力来源，可能会增加基站的运营成本。因此，为了降低基站的运营成本，可以控制基站停止采用市电作为电源，转而利用备用电池为自身提供工作所需的电能，避免基站继续采用电力特征值较高的市电作为电源。
S204：响应于备用电池的剩余电量不大于第一目标电量，或电力特征值不满足第一条件，控制基站从备用电池切换至市电进行供电。
在控制基站从市电切换至备用电池进行供电之后，可以对备用电池的剩余电量和电力特征值进行监控。如果检测到备用电池的剩余电量不大于第一目标电量，或者市电的电力特征值不满足第一条件，可以控制基站将供电电源从备用电池切换至市电。
如果备用电池的剩余电量小于第一目标电量，说明备用电池所储备的电能无法供应基 站在市电停电状态下继续工作第一预设时长，如果发生市电停电，基站可能无法继续工作足够长的第一预设时间。如果备用电池的剩余电量等于第一目标电量，那么如果继续使用备用电池为基站供电，会导致备用电池的剩余电量继续下降，也会导致基站在市电停电状态下无法工作第一预设时间。因此，如果检测到备用电池的剩余电量小于或等于第一目标电量，可以控制基站采用市电作为电力来源，停止消耗备用电池中所储备的电能，确保基站在市电停电状态下具有足够的电能为终端设备提供接入服务。
如果市电的电力特征值不满足第一条件，说明采用市电为基站提供电能的成本较低。这样，出于减少备用电池的充放电时间，延长备用电池的使用寿命的考虑，采用市电为基站供电所产生的运营成本可能小于采用备用电池为基站进行用电所产生的运营成本。因此，即使备用电池的剩余电量大于第一目标电量，如果市电的电力特征是不满足第一条件，也可以控制基站从备用电池转为市电作为电能的来源。
S205：响应于所述电力特征值满足第二条件，通过所述市电为所述备用电池充电。
在步骤S204中，基站可以使用备用电池中所储备的电能作为电力来源。为了补充备用电池中储备的电能，在一些可能的实现方式中，可以在电力特征值满足第二条件的情况下，通过市电为备用电池充电。其中，第二条件用于指示基站采用市电供电的成本较低，例如第二条件可以办理市电的电力特征值小于或等于第二阈值。可选地，第二阈值和前述第一阈值可以相同，也可以低于第一阈值。
举例说明。在一些可能的实现方式中，一天内市电的单位电价可能包括单位电价A、单位电价B和单位电价C三种市电电价。其中单位电价A大于单位电价B，单位电价B大于单位电价C。假设第一阈值为单位电价A，第二阈值为单位电价C，那么在市电的单位电价为单位电价A的情况下，如果备用电池的剩余电量大于第一目标电量，可以控制基站采用备用电池代替市电作为电力来源。如果市电的单位电价从单位电价A变化为单位电价B或单位电价C，或者备用电池的剩余电量小于第一目标电量，那么可以控制基站采用市电代替备用电池作为电力来源，以确保备用电池所储备的电能足够基站在市电停电状态下使用。进一步地，如果市电的单位电价降低至单位电价C，可以采用市电为备用电池进行充电，以待下一次市电电价上升时使用。如此，通过备用电池所储备的电能作为缓冲，实现了不同市电电价下的错峰用电，在保证备电足够的情况下降低了基站的运营成本。
在一些可能的实现方式中，当基站使用备用电池作为电力来源时，备用电池的剩余电量可能降低至第一目标电量或以下，而市电的用电成本可能较高。为了确保基站在市电停电状态下的正常工作，即使电力特征值满足第一条件，或电力特征值不满足第二条件，仍然可以控制市电为备用电池充电，确保备用电池中所储备的电能保持在第一目标电量之上。
在本申请实施例中，可以在基站的运营过程中对基站在未来的第一预设时间内可能承载的业务量进行预测，得到第一业务量，并根据对应关系确定基站承载第一业务量的业务所需的第一目标电量。确定停电状态下，维持基站在未来的第一预设时间内正常工作所需要的电量的最小值。接着，如果备用电池的剩余电量大于第一目标电量，说明可以利用备用电池实现错峰用电，降低基站的用电成本。那么在备用电池的剩余电量大于第一目标电量，且电力特征值满足第一条件的情况下，可以将基站的供电电源从市电切换到备用电池， 从而在当前时刻避免采用成本较高的市电进行供电。这样，由于错峰配电的过程中备用电池的剩余电量大于第一目标电量，即使市电停电，备用电池中所储备的电能仍然可以支持基站持续工作第一预设时间。如此，在保证基站的备电充足的基础上，实现了错峰供电，降低了基站的运营成本。
在上文的介绍中，备用电池可以在市电的用电成本较低时从市电存储电能，并在市电的用电成本较高时为基站提供电力来源，实现错峰用电，降低基站的运营成本。在这个过程中，备用电池的电量始终大于第一目标电量。在市电发生停电之后，可以采用备用电池所储备的电能作为基站的电力来源。
但是，根据前文介绍可知，第一目标电量是根据基站在第一预设时间内可能需要承载的业务量进行预测得到的。在一些应用场景中，基站在市电停电状态下承载的业务量可能比正常供电状态下承载的业务量更多，而且市电停电的时间可能也大于第一预设时间，导致基站需要在停电状态下承载更多的业务量。也就是说，在市电停电状态下，备用电池内所储备的电能可能无法支持基站承载全部业务。因此，在一些可能的实现方式中，在市电停电的情况下，可以根据备用电池剩余的电量控制基站拒绝支持部分业务，从而延长基站在市电停电下的工作时间。
下面结合图3，对停电状态下备用电池以及基站的控制方法进行介绍。参见图3，该图为停电状态下，本申请实施例提供的电池控制方法的方法流程图，包括：
S301：响应于市电处于停电状态，控制备用电池为基站供电，并获取备用电池的剩余电量。
在确定市电停电之后，可以控制备用电池为基站进行供电，保证基站在停电状态下的正常工作。在控制备用电池为基站进行供电之后，可以获取备用电池的剩余电量，以便及时调整基站的工作情况。
根据S202中的介绍可知，在计算第一目标电量的过程中，可以根据电量预留策略对第一业务量进行修正。其中电量预留策略用于指示基站在市电停电状态下拒绝支持部分业务。相应地，在控制备用电池为基站进行供电之后，可以控制基站根据电量预留策略的指示拒绝支持部分业务。
在本申请实施例中，电量预留策略可以用于指示基站关闭一种或多种业务的部分业务通道，也可以用于指示基站关闭一种或多种业务。其中，一种业务可以包括一个或多个业务通道，每个业务通道可以对应一个或多个终端设备。可选地，一个业务通道可以对应基站中一块通信板卡。
举例说明。假设基站在正常情况下可以支持5G NR业务、长期演进(Long Term Evolution，LTE)业务和全球通(global system for mobile，GSM)业务三种业务，那么在正常情况下，基站的功耗随时间的变化趋势可以如图4-A所示。其中，区域401表示5G NR业务的功耗，区域402表示LTE业务的功耗，区域403表示G业务的功耗。在市电发生停电之后，基站可以根据电量预留策略关闭一种或多种业务，或关闭一种或多种业务的一个或多个业务通道。下面分别进行介绍。
在第一种可能的实现方式中，电量预留策略用于指示基站在市电停电后关闭5G NR业 务的部分业务通道。即，基站可以在市电停电之后拒绝支持部分5G NR业务，例如基站可以关闭部分5G NR业务对应的通信板卡。那么基站的功耗随时间的变化趋势可以如图4-B所示，其中，t1为发生市电停电的时刻，区域404表示市电停电后5G NR业务的功耗，剩余各个区域所表示的含义与图4-A中相同。从图4-B中可以看出，基站的5G NR业务的功耗在停电后降低，从而减少了基站的总功耗，延长了基站在市电停电状态下的工作时间。
在第二种可能的实现方式中，电量预留策略用于指示基站在市电停电后关闭5G NR业务的部分业务通道和LTE业务的部分业务通道。即，基站可以在市电停电之后拒绝支持部分5G NR业务和部分LTE业务。那么基站的功耗随时间的变化趋势可以如图4-C所示，其中，t1为发生市电停电的时刻，区域405表示市电停电后LTE业务的功耗，剩余各个区域所表示的含义与图4-B中相同。从图4-C中可以看出，基站的5G NR业务的功耗和LTE业务的功耗在停电后降低，从而减少了基站的总功耗，延长了基站在市电停电状态下的工作时间。另外，相较于第一种可能的实现方式，由于基站还关闭了LTE业务的部分业务通道，可以进一步降低基站的功耗，延长了基站在停电状态下的使用时间。
在第三种可能的实现方式中，电量预留策略可以用于指示基站在市电停电后关闭5G NR业务。其中，关闭5G NR业务可以指关闭5G NR业务对应的多个业务通道。另外，为了避免恢复供电后重新连接，可以在关闭5G NR业务的同时保留5G NR业务的呼吸连接。即，基站的功耗随时间的变化趋势可以如图4-D所示，其中t1为发生市电停电的时刻，区域404表示维持5G NR业务呼吸连接的功耗，区域406表示市电停电后5G NR业务的功耗，剩余各个区域所表示的含义与图4-A中相同。如此，相较于第一种实现方式，由于关闭了5G NR业务，仅保留5G NR业务的呼吸连接，进一步降低了基站的功耗，延长基站在停电状态下的使用时间。
在第四种可能的实现方式中，电量预留策略可以用于指示基站在市电停电后关闭5G NR业务和LTE业务。其中，关闭LTE业务可以指关闭LTE业务对应的多个业务通道。另外，为了避免恢复供电后重新连接，可以在关闭LTE业务的同时保留LTE业务的呼吸连接。那么基站的功耗随时间的变化趋势可以如图4-E所示，其中t1为发生市电停电的时刻，区域405表示维持LTE业务呼吸连接的功耗，区域407表示市电停电后LTE业务的功耗，剩余各个区域所表示的含义与图4-D中相同。如此，相较于前三种实现方式，由于关闭了更多的业务，进一步降低了基站的功耗，进一步延长基站在停电状态下的使用时间。
需要说明的是，上述四种可能的实现方式仅作为示例给出，并不代表全部可能的实现方式。在实际的应用场景中，可以根据基站的需求控制基站关闭任意业务或业务通道。
S302：响应于剩余电量不大于第二目标电量，根据剩余电量确定预设控制策略。
随着基站的运行，备用电池的剩余电量会不断减少。在这个过程中，可以多次获取备用电池的剩余电量，并比较剩余电量和第二目标电量的大小(第二目标电量小于第一目标电量)。如果备用电池的剩余电量降低至第二目标电量或以下，说明备用电池中储备的电能不足。如果基站继续维持当前业务，可能在恢复供电之前将备用电池中的电量耗尽，导致基站停止工作。因此，为了尽可能地延长基站的运营时间，可以在备用电池的剩余电量不大于第三目标电量的情况下，根据剩余电量确定预设控制策略。
其中，预设控制策略用于指示基站关闭第二业务，第二业务可以是基站在停电状态下支持的任意业务。也就是说，在市电停电的状态下，如果备用电池的剩余电量低至第二目标电量或以下，可以控制基站进一步关闭第二业务，以延长基站在停电状态下的运营时间。
在一些可能的实现方式中，备用电池的剩余电量不同，对应的预设控制策略也不同。可选地，备用电池的剩余电量越低，预设控制策略要求基站关闭的业务可能越多。例如，假设基站在正常情况下支持5G NR业务、LTE业务和G业务三种业务，那么预设控制策略可以以表1的形式表示。
表1
剩余电量(百分比) 预设控制策略
50％≤X<100％ -
25％≤X<50％ 关闭5G NR业务
10％≤X<25％ 关闭LTE业务
X<10％ 关闭G业务
其中，X表示备用电池的剩余电量占备用电池的总电量的占比。从表1中可以看出，备用电池的剩余电量越低，基站拒绝支持的业务也就越多。
那么，在基站运行的过程中，可以根据备用电池的剩余电量调整预设控制策略。例如，如果检测到备用电池的剩余电量低于第三目标电量(第三目标电量小于第二目标电量)，可以根据第三目标电量调整预设控制策略。
S303：根据预设控制策略控制基站关闭第二业务。
在确定预设控制策略之后，可以根据预设策略控制基站关闭第二业务，降低基站的负载，从而降低基站的耗电量。
举例说明。假设基站在正常情况下可以支持5G NR业务、LTE业务和G业务三种业务，那么在正常情况下，基站的功耗随时间的变化趋势可以如图4-A所示。在市电停电之后，基站采用备用电池作为电力来源，那么基站的功耗随时间的变化趋势可以如图5所示。
其中，t1为市电停电的时刻，t2为剩余电量达到第二目标电量的时刻，t3为剩余电量达到第三目标电量的时刻。其中，区域501为正常供电状态下5G NR业务的功耗，区域502为正常供电状态下LTE业务的功耗，区域503为正常供电状态下G业务的功耗。
在市电停电之后，可以控制基站关闭5G NR业务的部分业务通道，那么基站支持5G NR业务的功耗从区域501降低为区域504。在备用电池的剩余电量降低至第二目标电量时(即t2时刻)，基站可以拒绝继续支持5G NR业务，并关闭LTE业务的部分业务通道，仅保留5G NR业务的心跳连接。那么基站在5G NR业务上的功耗从区域504进一步降低至区域505，在LTE业务上的功耗从区域502降低至区域506。
在备用电池的剩余电量降低至第三目标电量时(即t3时刻)，基站可以拒绝继续支持LTE业务，仅保留LTE业务的心跳连接。那么基站在LTE业务上的功耗从区域506进一步降低至区域507。如此，通过设置多种电量预留策略，在延长基站运行时间的基础上，能够为终端设备提供更多的服务。
