一种载波关断方法、装置及设备 技术领域
本申请涉及通信技术领域，特别涉及一种载波关断方法、装置及设备。
背景技术
载波关断是在多个载波重叠覆盖的区域，在业务量低的时间段且网络资源存在冗余时，关断部分冗余载波，达到节省网络资源和能耗的目的。
目前，载波关断主要在夜间空载(欧洲电信标准协会(European Telecommunications Standards Institute，ETSI)模型10％以下负载)时间段开展，该空载时间段一般为0点至6点的6个小时。
但是，随着网络越来越厚，重覆盖层数越来越大，例如在中载(ETSI模型30％负载，6点至9点的3个小时和17点至24点时间的7个小时(共10个小时))情况下，该中载也可以考虑载波关断，可目前没有针对中载情况下进行载波关断的优化方案。
发明内容

载波关断是通信领域常用的节能方法，原则是在多个载波重叠覆盖的区域，在业务量低的时间段且网络资源存在冗余时，关断部分冗余载波，达到节省网络资源和能耗的目的。
目前，载波关断主要在夜间空载时间段开展，该空载时间段一般为0点至6点的6个小时。
但是，随着网络越来越厚，重覆盖层数越来越大，通过灵活、精准的业务调度，在中载情况下也可以主动创造载波关断机会，可目前没有针对中载情况下进行载波关断的优化方案。
在中载情况下，主动载波关断需要大量业务迁移，准确性不够会带来业务性能的影响，对业务迁移的准确性有较高的要求。尤其是异构等复杂覆盖网络的存在，给业务迁移和载波关断的准确性带来挑战。
因此，为了解决上述技术问题，本申请提供了一种载波关断方法、装置及设备，通过确定第一载波的每个覆盖子区域的负载，若每个覆盖子区域的其他载波能够承载该负载，则将该负载迁移到其他载波，并关断第一载波，提高了载波关断的准确性，节省了网络消耗。
本申请中的终端，可以是用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是指向用户提供语音和/或数据连通性的设备。例如，具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人 驾驶(self-driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
本申请中的网络设备，是指将终端接入到无线网络的无线接入网(radio access network，RAN)节点或RAN设备，又可以称为基站。目前，一些RAN节点的举例为：下一代节点(next generation Node B，gNB)、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，WiFi)接入点(access point，AP)等。
下面通过具体实施例进行说明。
图1是本申请实施例提供的一种载波关断方法的应用系统架构图。如图1所示，该应用系统架构图中包括网管、基站收发信站点(Base Transceiver Station，BTS)、小区C0、小区C1、…、小区Cn。其中，网管负责下发载波调度策略，比如：载波关断的时间段设置，关断载波的选择策略，载波的业务门限等；BTS负责关断载波的选择，载波关断条件预判，载波唤醒预判；小区负责业务迁移、业务切换等。
图2是本申请实施例提供的一种载波关断方法的实现场景示意图。如图2所示，MAE可以按照C0、C1、C2、C3、C4之间重覆盖资源的不同，将关断目标载波C0切分为多个子区域，即A2-1、A2-2、A3、A4，实时识别各个子区域中的实际业务量。其中，C0、C1、C2、C3、C4之间重覆盖资源可以包括重复盖载波和载波层数，具体如下述表1所示。
表1
子区域划分 各子区域业务量 重覆盖载波数 重覆盖载波和业务迁移对象
A2-1 L(A2-1) 1 C3
A2-2 L(A2-2) 1 C4
A3 L(A3) 2 C2、C3
A4 L(A4) 3 C1、C2、C3
MAE在判决业务迁移可行性时，按照每个子区域计算业务迁移量及迁移后的载波负载情况，具体如下述表2所示。
表2
Figure PCTCN2021087571-appb-000001
Figure PCTCN2021087571-appb-000002
MAE可以根据业务迁移后各个重覆盖小区(C1、C2、C3、C4)的业务量L(Cx)和业务门限MaxL(Cx)判断，若每个小区都满足设定条件，则可以进行业务迁移并关断小区(C0)。其中，设定条件为迁移后重覆盖小区的业务量L(Cx)小于该小区的业务门限MaxL(Cx)。
另外，当一个载波Cx(C1～C4中某一个)业务量抬升达到业务门限MaxL(Cx)时，同样按照重覆盖资源(不包括C0)的不同将载波Cx切分为多个子区域，计算按照均衡原则定向将业务迁移到重复盖资源，如果迁移后所有载波业务低于业务门限，迁移业务，不唤醒C0。如果计算迁移后有载波负载高于业务门限，唤醒载波C0。
可见，本申请中的载波关断可以实现：
(1)精准业务预估，即按照重覆盖小区的重复层数，将关断目标载波C0切分为多个区域，按照区域为维度，根据各区域的实时待迁移业务量和可接纳业务的载波负荷量，预估载波关断后的可接纳负载的各载波负荷量，精准预判关断可行性，避免误判对业务影响。
(2)区域级业务均衡切换，即当关断的目标载波C0或者区域内负荷高于一定门限的载波Cx的业务，“精准业务预估”后满足业务迁移条件后，合理的安排一个或者多个业务接受载波，做定向定量业务切换，使区域内的各载波负荷区域均匀。
通过以上描述可知，正由于业务的不均匀分布和异构覆盖，中载场景下载波业务迁移容易出错。通过精细化载波业务迁移预判，在不影响现网业务影响下，将业务精准集中，关断部分载波，实现中载下载波关断，节省了网络功耗。
本申请中的载波关断方法可以用于在四频以及以上的场景，ETSI中载业务时间段。其中，以4频段重覆盖站点为例，计算收益如下述表3所示。

从表3中可以看出每个扇区可节能94W，中载时间段为10小时/天，则每年节能1029kWh/站，这样不但实现了中载下载波关断，还节省了网络功耗。
接下来，请参阅图3和图4，图3是本申请实施例提供的一种载波关断方法的流程示意图，图4是本申请实施例提供的一种载波关断方法的实现场景示意图；该载波关断方法可以用于网络设备，比如：图1中的BTS。如图3所示，该载波关断方法可以包括以下步骤：
S301、确定第一载波的第一覆盖子区域的第一负载和第一载波的第二覆盖子区域的第二负载，第一载波对应第一小区，第一覆盖子区域是第一载波和第二载波的重覆盖区域，第二覆盖子区域是第一载波和第三载波的重覆盖区域。
具体地，如图4所示，第一载波为C0，第二载波为C3，第三载波为C4，第一覆盖子区域为覆盖子区域1(即C0和C3的重覆盖区域)，第二覆盖子区域为覆盖子区域2(即C0和C4的重覆盖区域)。
本申请实施例以图4中的C0包括两个覆盖子区域(即覆盖子区域1和覆盖子区域2)为例来描述载波关断的实现过程，至于C0包括三个覆盖子区域和三个以上覆盖子区域的情形，其与包括两个覆盖子区域的的实现过程类似，在这里不再赘述。
S302、当第二载波在第一覆盖子区域内能够承载第一负载，且第三载波在第二覆盖子区域内能够承载第二负载时，将第一负载迁移到第二载波，以及将第二负载迁移到第三载波，并关断第一载波。
具体地，如图4所示，若C3能够承载C0在覆盖子区域1的负载和C4能够承载C0在覆盖子区域2的负载，此时可以将C0在覆盖子区域1的负载迁移到C3，以及将C0在覆盖子区域2的负载迁移到C4，并关断C0，这样即使在中载场景下也可以关断部分载波，实现中载下载波关断，节省了网络功耗。
在一些实施例中，第二载波可以包括多个载波；第二载波在第一覆盖子区域内能够承载第一负载可以包括多个载波在第一覆盖子区域内能够承载第一负载；上述S302中在将第一负载迁移到第二载波时可以包括：根据多个载波当前承载的负载量将第一负载迁移到多个载波；或者，多个载波均分第一负载。
具体地，如图5所示，C1、C2和C3的重覆盖区域均为覆盖子区域1，若C1、C2和C3在覆盖子区域1能够承载C0在覆盖子区域1的负载，此时可以将C0在覆盖子区域1的负载迁移到C1、C2和C3。至于如何将C0在覆盖子区域1的负载迁移到C1、C2和C3，有很多种方式。比如：根据C1、C2和C3当前承载的负载量将C0在覆盖子区域1的负载迁移到C1、C2和C3。又比如：C1、C2和C3均分C0在覆盖子区域1的负载。
在一些实施例中，第三载波包括多个载波；第三载波在第二覆盖子区域内能够承载第二负载包括多个载波在第二覆盖子区域内能够承载第二负载；上述S302中在将第二负载迁移到第三载波时可以包括：根据多个载波当前承载的负载量将第二负载迁移到多个载波；或者，多个载波均分第二负载。
具体地，如图6所示，C4和C5的重覆盖区域均为覆盖子区域2，若C4和C5在覆盖子区域2能够承载C0在覆盖子区域2的负载，此时可以将C0在覆盖子区域2的负载迁移到C4和C5。至于如何将C0在覆盖子区域2的负载迁移到C4和C5，有很多种方式。比如：根据C4和C5当前承载的负载量将C0在覆盖子区域2的负载迁移到C4和C5。又比如：C4和C5均分C0在覆盖子区域2的负载。
在一些实施例中，上述执行S302之后，该载波关断方法还可以包括：当第二载波在第一覆盖子区域内不能承载第一负载和/或第三载波在第二覆盖子区域内不能承载第二负载时，唤醒第一载波。
具体地，如图4所示，为了避免载波关断所造成的业务性能影响，满足一些条件时，可以唤醒C0。其中，这些条件可以为C3不能承载C0在覆盖子区域1的负载；还可以为C4不能承载C0在覆盖子区域2的负载；也可以为C3不能承载C0在覆盖子区域1的负载且C4不能承载C0在覆盖子区域2的负载。
在一些实施例中，上述执行S302之后，该载波关断方法还可以包括：当第二载波在第一覆盖子区域内不能承载第一负载时，确定第二载波的第三覆盖子区域的第三负载，第三覆盖子区域是第二载波和第四载波的重覆盖区域；当第四载波在第三覆盖子区域内能够承载第三负载时，将第三负载迁移到第四载波。
具体地，如图7所示，在C3不能承载C0在覆盖子区域1的负载时可以确定C3在覆盖子区域3的负载，覆盖子区域3是C3和C6的重覆盖区域，当C6在覆盖子区域3能够承载C3在覆盖子区域3的负载时，此时将C3在覆盖子区域3的负载迁移到C6。
在一些实施例中，第四载波包括多个载波；第四载波在第三覆盖子区域内能够承载第三负载包括多个载波在第三覆盖子区域内能够承载第三负载；将第三负载迁移到第四载波，包括：根据多个载波当前承载的负载量将第三负载迁移到多个载波；或者，多个载波均分第三负载。
具体地，如图8所示，C6和C7的重覆盖区域均为覆盖子区域3，若C6和C7在覆盖子区域3能够承载C3在覆盖子区域3的负载，此时可以将C3在覆盖子区域3的负载迁移到C6和C7。至于如何将C3在覆盖子区域3的负载迁移到C6和C7，有很多种方式。比如：根据C6和C7当前承载的负载量将C3在覆盖子区域3的负载迁移到C6和C7。又比如：C6和C7均分C3在覆盖子区域3的负载。
在一些实施例中，当第四载波在第三覆盖子区域内不能承载第三负载时，唤醒第一载波。
具体地，如图7所示，当C6在覆盖子区域3不能承载C3在覆盖子区域3的负载时，此时仍然需要唤醒C0，从而保证了通信质量。
在一些实施例中，上述执行S302之后，该载波关断方法还可以包括：第三载波在第二覆盖子区域内不能承载第二负载时，确定第三载波的第四覆盖子区域的第四负载， 第四覆盖子区域是第三载波和第五载波的重覆盖区域；当第五载波在第四覆盖子区域内能够承载第四负载时，将第四负载迁移到第五载波。
具体地，如图9所示，在C4不能承载C0在覆盖子区域2的负载时可以确定C4在覆盖子区域4的负载，覆盖子区域4是C4和C8的重覆盖区域，当C8在覆盖子区域4能够承载C4在覆盖子区域4的负载时，此时可以将C4在覆盖子区域4的负载迁移到C8。
在一些实施例中，第五载波包括多个载波；第五载波在第四覆盖子区域内能够承载第四负载包括多个载波在第四覆盖子区域内能够承载第四负载；将第四负载迁移到第五载波，包括：根据多个载波当前承载的负载量将第四负载迁移到多个载波；或者，多个载波均分第四负载。
具体地，如图10所示，C8和C9的重覆盖区域均为覆盖子区域3，若，C8和C9在覆盖子区域4能够承载C4在覆盖子区域4的负载，此时可以将C4在覆盖子区域4的负载迁移到C8和C9。至于如何将C4在覆盖子区域4的负载迁移到C8和C9有很多种方式。比如：根据C8和C9当前承载的负载量将C4在覆盖子区域4的负载迁移到C8和C9。又比如：C8和C9均分C4在覆盖子区域4的负载。
在一些实施例中，当第五载波在第四覆盖子区域内不能承载第四负载时，唤醒第一载波。
具体地，如图9所示，当C8在覆盖子区域4不能承载C4在覆盖子区域4的负载时，此时仍然需要唤醒C0，从而保证了通信质量。
