一种无线参数调整方法和装置 技术领域
本申请涉及无线通信技术领域，尤其涉及一种无线参数调整方法和装置。
背景技术
无线参数调整方案中，一般以特定的关键性能指标(key performance indicator，KPI)作为目标，来设计不同的无线参数调整的性能优化方案。例如现有技术中的导频功率调整方案、切换参数优化方案、语音参数优化方案、长期演进语音承载(voice over long-term evolution，VOLTE)优化参数方案、节能方案等。但是，上述几种无线参数调整方案仅能保障无线网络中特定的KPI。
在第三代合作伙伴计划(3 rd generation partnership project，3GPP)协议中引入了网络数据分析(network data analytics，NWDA)网元，对无线网络中的参数分析相关策略进行了定义。但是，当前3GPP协议中并没有保障无线网络中KPI的相关方法。

本申请实施例中，信息(information)，信号(signal)，消息(message)，信道(channel)有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。“的(of)”，“相应的(corresponding，relevant)”和“对应的(corresponding)”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请实施例既可以应用在传统的典型网络中，也可以应用在未来的以UE为中心(UE-centric)的网络中。UE-centric网络引入无小区(Non-cell)的网络架构，即在某个特定的区域内部署大量小站，构成一个超级小区(Hyper cell)，每个小站为Hyper cell的一个传输点(Transmission Point,TP)或传输接收点(Transmission and Reception Point,TRP)，并与一个集中控制器(controller)相连。当UE在Hyper cell内移动时，网络侧设备时时为UE选择新的sub-cluster(子簇)为其服务，从而避免真正的小区切换，实现UE业务的连续性。其中，网络侧设备包括无线网络设备。或者是，在以UE为中心的网络中，多个网络侧设备，如小站，可以有独立的控制器，如分布式控制器，各小站能够独立调度用户，小站之间在长期上存在交互信息，使得在为UE提供协作服务时，也能够有一定的灵活性。

为便于理解本申请实施例，首先以图1中示出的通信***为例详细说明适用于本申请实施例的通信***。图1示出了适用于本申请实施例的通信方法的通信***的示意图。如图1所示，该通信***100包括网络设备102和终端设备106，网络设备102可配置有多个天线，终端设备也可配置有多个天线。可选地，该通信***还可包括网络设备104，网络设备104也可配置有多个天线。
应理解，网络设备102或网络设备104还可包括与信号发送和接收相关的多个部件(例如，处理器、调制器、复用器、解调器或解复用器等)。
其中，网络设备为具有无线收发功能的设备或可设置于该设备的芯片，该设备包括但 不限于：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(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WIFI)***中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission and reception point，TRP或者transmission point，TP)等，还可以为5G，如，NR，***中的gNB，或，传输点(TRP或TP)，5G***中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(DU，distributed unit)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括射频单元(radio unit，RU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)和物理(physical，PHY)层的功能。由于RRC层的信息最终会转变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PDCP层信令，也可以认为是由DU发送的，或者，由DU+CU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网RAN中的网络设备，也可以将CU划分为核心网CN中的网络设备，在此不做限制。
RAN设备可以由一个节点实现RRC、PDCP、RLC和MAC等协议层的功能；或者可以由多个节点实现这些协议层的功能；例如，在一种演进结构中，RAN设备可以包括CU和DU，多个DU可以由一个CU集中控制。CU和DU可以根据无线网络的协议层划分，例如PDCP层及以上协议层的功能设置在CU，PDCP以下的协议层，例如RLC层和MAC层等的功能设置在DU。
这种协议层的划分仅仅是一种举例，还可以在其它协议层划分，例如在RLC层划分，将RLC层及以上协议层的功能设置在CU，RLC层以下协议层的功能设置在DU；或者，在某个协议层中划分，例如将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。此外，也可以按其它方式划分，例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。
此外，射频装置可以拉远，不放在DU中，也可以集成在DU中，或者部分拉远部分集成在DU中，在此不作任何限制。
参考图2所示的网络架构，还可以将CU的控制面(CP)和用户面(UP)分离，分成不同实体来实现，分别为控制面CU实体(CU-CP实体)和用户面CU实体(CU-UP实体)。
在以上网络架构中，CU产生的信令可以通过DU发送给终端设备，或者终端设备产生的信令可以通过DU发送给CU。DU可以不对该信令进行解析而直接通过协议层封装而透传给终端设备或CU。以下实施例中如果涉及这种信令在DU和终端设备之间的传输，此时，DU对信令的发送或接收包括这种场景。例如，RRC或PDCP层的信令最终会处理为PHY层的信令发送给终端设备，或者，由接收到的PHY层的信令转变而来。在这种架构下，该RRC或PDCP层的信令，即也可以认为是由DU发送的，或者，由DU和射频 装载发送的。
在以上实施例中可以将CU划分为RAN侧的网络设备，此外，也可以将CU划分为CN侧的网络设备，在此不做限制。
本申请以下实施例中的装置，根据其实现的功能，可以位于终端设备或网络设备。当采用以上CU-DU的结构时，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的RAN设备。
终端设备也可以称为用户设备(user equipment，UE)、接入终端设备、用户单元、用户站、移动站、移动台、远方站、远程终端设备、移动设备、用户终端设备、终端设备、无线通信设备、用户代理或用户装置。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self driving)中的无线终端设备、远程医疗(remote medical)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本申请的实施例对应用场景不做限定。本申请中将具有无线收发功能的终端设备及可设置于前述终端设备的芯片统称为终端设备。
在该通信***100中，网络设备102和网络设备104均可以与多个终端设备(例如图中示出的终端设备106)通信。网络设备102和网络设备104可以与类似于终端设备106的一个或多个终端设备通信。但应理解，与网络设备102通信的终端设备和与网络设备104通信的终端设备可以是相同的，也可以是不同的。图1中示出的终端设备106可同时与网络设备102和网络设备104通信，但这仅示出了一种可能的场景，在某些场景中，终端设备可能仅与网络设备102或网络设备104通信，本申请对此不做限定。
应理解，图1仅为便于理解而示例的简化示意图，该通信***中还可以包括其他网络设备或者还可以包括其他终端设备，图1中未予以画出。
在无线网络环境中，在优化网络KPI的过程时，需要不断的调整小区的无线参数以得到最佳的无线网络性能。本申请实施例中将增强学习应用于无线网络参数调整方案。增强学习是智能体(agent)在环境中采取一系列的行为，从而获得最大的累积回报。由于增强学习没有直接的指导信息，智能体要不断与环境进行交互，通过多种尝试的方式来获得最佳策略。通过增强学习，一个智能体可以知道在什么状态下应该采取什么行为。下面对增强学习过程进行详细说明。
一个增强学习过程通常包括以下三个元组：
S：表示状态集(state)，有s i∈S，s i表示第i步的状态；
A：表示一组动作(action)，有a i∈A，a i表示第i步的动作；
R：S×A→R，R是回报函数(reward function)。如果一组(s 1,a 1)转移到了下一个状态s 2，那么回报函数可以记为r(s 2|s 1,a 1)。如果(s 1,a 1)对应的下一个状态s 2是唯一的，那么回报函数也可以记为r(s 1,a 1)。
增强学习的过程可以表示成一个马尔科夫决策过程：一个智能体的初始状态为s 0，然后从A中挑选一个动作a 0执行，执行后环境(environment)转移到了下一个s 1状态，然后再执行一个动作a 1，环境转移到了s 2，以此类推。
无线资源管理(radio resource management，RRM)中有很多参数，且不少是默认和固 定的，而默认的参数设置对每个小区而言并不是最优的，不能最大化无线网络效率。例如，用户的移动和流量模式的变化也要求无线参数变化。因此，可以将前面提到的增强学习用于无线参数的调整，寻找最优的无线参数。例如，可以将增强学习应用于导频调整、天线倾角和方位角调整等多个无线的功能中。
可以在设计阶段将无线网络需要的状态集、动作和回报函数预先定义，并将定义好的算法用于无线参数调整。但是，这种做法不够灵活，无法修改和调整算法，不能给出最合适***的状态集、动作和回报函数。另一方面，无线网络对KPI要求严格，要求参数调整过程中KPI不能有较大下降。因此，往往还需要引入KPI保证策略。现有技术中，一般以特定的KPI作为目标，来设计不同的无线参数调整的性能优化方案。但是，这种无线参数调整方案仅能在特定的方案中保障无线网络中特定的KPI。另外，在3GPP协议中对无线网络中的参数分析相关策略进行了定义。但是，当前3GPP协议中并没有保障无线网络中KPI的相关方法。
因此，在需要一种保障无线网络中KPI的无线参数调整方法，可以在无线参数调整的时候有效对无线网络的总KPI进行保障，同时提升无线网络性能。
基于上述需求，本申请实施例提供一种无线参数调整方法。图3是从设备交互的角度示出的本申请实施例提供的无线参数调整方法的示例性流程图。如图3所示，该方法可以包括以下步骤：
步骤301：网络数据分析单元NWDA从网络管理***NMS获取KPI和所述KPI的数据。需要说明的是，对于没有定义NWDA的***，具有针对无线数据进行分析的模块就可以看做是NWDA网元。
这里的KPI是网络运维人员关心的无线网络指标。可以但不限于包括无线接通率，无线接通率用于反映UE接入网络的成功率。或者，KPI还可以包括切换成功率，切换是移动通信***的一个非常重要的功能，切换成功率用于标识UE在不同小区切换时保持连续通话的成功率。或者，KPI还可以包括无线掉话率，无线掉话率用于表示UE被异常释放的比例。
在一个可能的实现方式中，无线网络环境中的CU和DU等网元将各个小区的无线参数和参数值等信息上报到NMS，以使NMS根据无线参数和参数值等信息确定无线网络环境中的KPI。其中，针对一个小区，无线参数可以包括导频功率、导频配比、天线下倾角、天线方位角、本小区和邻区负载、用户数、和参考信号接收功率(reference signal received power，RSRP)等及对应的参数值。
步骤302：所述网络数据分析单元NWDA根据所述KPI和所述KPI的数据，确定KPI数据信息。这里的KPI数据信息可以包含需要保障的第一KPI以及所述第一KPI对应的门限。
在一种可能的实现方式中，NWDA可以根据获取到的KPI确定当前的网络场景。并根据预设的网络场景与KPI数据信息的对应关系，确定当前网络场景对应的KPI数据信息。
在不同的网络场景下，可以根据经验值预先设置不同的KPI保障信息。这里的网络场景可以是不同的地理位置，如城区、郊区等。例如，城区的KPI保障信息可以包括无线接通率的门限为98％、切换成功率的门限为98％；郊区的KPI保障信息可以包括无线接通率的门限为90％、切换成功率的门限为90％等。或者，网络场景也可以是不同的网络规模，如接入UE很多，接入UE较少等。其中，接入UE的多少可以通过预设的阈值确定，例 如接入的UE大于等于阈值可以确定为接入UE很多，接入的UE小于阈值可以确定为接入UE很少。例如，在接入的UE大于等于阈值时，KPI保障信息可以包括无线接通率的门限为98％、切换成功率的门限为98％，和无线掉话率的门限为0.1％；在接入的UE小于阈值时，KPI保障信息可以包括无线接通率的门限为95％、切换成功率的门限为96％，和无线掉话率的门限为0.2％。又或者，网络场景还可以是不同业务体验需求，如UE是通话需求，或者UE是数据连接需求等。
在另一示例中，不同的网络场景还可以预先设置相同的KPI保障信息，或者不同的网络场景可以预先设置部分相同的KPI保障信息。
另一种可能的实现方式中，NWDA还可以获取预设的KPI数据信息。其中，KPI数据信息根据经验值预先确定，本申请不做具体限定。
步骤303：所述网络数据分析单元NWDA将所述KPI数据信息发送给集中式单元CU。
步骤304：所述集中式单元CU获取无线网络中至少一个小区中每一个小区分别对应的第一KPI。
在一种可能的实现方式中，CU可以向NMS发送KPI数据请求。其中，KPI请求包含至少一个小区中每一个小区的标识，以及需要获取的第一KPI指示信息。NMS可以根据第一KPI指示信息，获取所述至少一个小区中每一个小区的第一KPI，并将获取到的第一KPI发送给CU。
另一可能的实现方式中，KPI请求还包括数据时间长度和数据时间间隔。其中，数据时间长度可以是某一时间长度的KPI，例如10s内小区的KPI。数据时间间隔可以是特定间隔周期下的KPI，如可以是每秒钟的KPI，每分钟的KPI，每小时的KPI等。
举例来说，CU向NMS发送的KPI数据请求中包含cell1、cell2，以及第一KPI指示信息为无线接通率和切换成功率、数据时间长度为5s、数据时间间隔为1s。则NMS获取cell1和cell2的5s前的无线接通率和切换成功率。其中，无线接通率和切换成功率均是每秒钟的。
步骤305：所述集中式单元CU将所述每一个小区的第一KPI分别与所述门限进行比较，得到需要进行无线参数调整的目标小区。
在一种可能的实现方式中，CU将每一个小区的第一KPI分别于门限进行比较，将第一KPI不满足所述门限的每一个小区作为目标小区。一示例中，CU可以将全部第一KPI均不满足所述门限的每一个小区作为需要进行无线参数调整的目标小区。另一示例中，CU可以将部分第一KPI不满足所述门限的每一个小区作为需要进行无线参数调整的目标小区。
举例来说，CU获取到的KPI数据信息包括无线接通率的门限为98％，以及获取到cell1的无线接通率为95％，cell2的无线接通率为98％，cell3的无线接通率为98.5％。则CU确定需要进行无线参数调整的目标小区为cell1。又例如，CU获取到的KPI数据信息包括无线接通率的门限为97％、切换成功率为98％，以及获取到cell1的无线接通率为98％、切换成功率为97％，cell2的无线接通率为98％、切换成功率为98.5％，cell3的无线接通率为96％、切换成功率为96％，则CU可以确定cell1和cell2为需要进行无线参数调整的目标小区。
另一种可能的实现方式中，若至少一个小区中存在至少两个小区能够组合为一个组合小区，则CU根据第一KPI的门限确定组合小区的第一KPI是否满足所述门限。若所述组合小区的第一KPI不满足所述门限，则CU确定所述组合小区中每一个小区的第一KPI是 否满足所述门限。CU将不满足所述门限的每一个小区作为目标小区。
这里的组合小区可以是预先存储于CU中的，也可以CU从NWDA获取的。
需要说明的是，组合小区的第一KPI可以是根据组合小区中每一个小区的第一KPI得到的。例如，组合小区的第一KPI可以是组合小区中每一个小区的第一KPI的平均数。
一示例中，CU可以在组合小区的全部第一KPI均不满足所述门限时，确定组合小区中每一个小区的第一KPI是否满足所述门限。另一示例中，CU可以在组合小区的部分第一KPI不满足所述门限时，确定组合小区中每一个小区的第一KPI是否满足所述门限。
举例来说，cell1和cell2、cell3为组合小区a，cell4和cell5为组合小区b。CU获取到的KPI数据信息包括无线接通率的门限为98％，切换成功率为97％。CU获取cell1的无线接通率为98.3％、切换成功率为97％，cell2的无线接通率为99％、切换成功率为96％,cell3的无线接通率为98.7％、切换成功率为95％，cell4的无线接通率为97.4％、切换成功率为99％，cell5的无线接通率为99.2％、切换成功率为97％。CU确定组合小区a的无线接通率为98.6％、切换成功率为96％，组合小区b的无线接通率为98.3％、切换成功率为98％。由于组合小区a的第一KPI不满足所述门限，CU将组合小区a中每一个小区的第一KPI与所述门限进行比较。CU可以确定cell2和cell3为需要进行无线参数调整的目标小区。
步骤306：所述集中式单元CU将所述目标小区的标识发送给分布式单元DU。
在一示例中，CU可以将目标小区的标识发送给DU，DU调整目标小区的无线参数。在另一示例中，CU可以将目标小区的标识、以及目标小区的第一KPI中不满足所述门限的第一KPI发送给DU。
步骤307：所述分布式单元DU调整所述目标小区的无线参数。
在一种可能的实现方式中，在将增强学习应用于无线参数调整方案时，CU可以将目标小区的无线参数执行回退操作或者前进操作。其中，回退操作可以是回退预设步骤，例如可以回退一步、或者可以回退两步等。同样的，前进操作也可以是前进预设步骤，例如可以前进一步、或者前进两步等。
例如，在调整无线参数时，智能体执行a 2动作，CU获取无线网络中的目标小区为cell2，并将cell2发送给DU。此时，DU可以使得智能体执行a 2动作的前一动作，例如可以使得智能体执行a 1动作，或者使得智能体执行a 0动作。
本申请实施例中DU在对目标小区的无线参数进行调整后，可以将目标小区的调整结果发送给CU。其中，调整结果可以包含无线网络中调整的无线参数以及调整后的参数值。
在一种可能的实现方式中，CU可以将调整结果发送给NWDA。NWDA根据调整结果中的无线参数以及参数值，重新确定KPI数据信息。其中，NWDA可以根据无线网络中的无线参数以及参数值，确定当前网络场景。并可以根据网络场景，重新确定KPI数据信息。
另一种可能的实现方式中，CU可以将调整结果发送给NMS。NMS可以根据无线网络中的无线参数和参数值，更新第一KPI。例如，无线网络中的第一KPI中无线接通率为97％，在接收到调整结果后根据无线网络中的无线参数和参数值，更新后的无线接通率为97.5％。
