Description

无线链路信息获取、分析、指示方法、设备及介质
本申请要求于2020年06月24日提交中国专利局、申请号为202010588811.3、发明名称为“ 无线链路信息获取、分析、指示方法、设备及介质”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，尤其涉及一种无线链路信息获取、分析、指示方法、设备及介质。
背景技术
终端，例如用户设备(user equipment,UE)，在执行小区间的切换时，不合适的切换参数引起的无线链路失败对用户体验及网络资源都有影响，对此，引入了移动性鲁棒性优化(mobility robust optimization，MRO)，MRO的目的是通过对系统间切换进行监测、识别、统计，然后确定对相关系统间切换参数进行调整以改变系统间切换的难易程度，以达到最小化系统间切换的异常，尽可能减少系统间切换性能的降低。
在5G新空口系统(new radio，NR)下，也引入了MRO优化，除了继承了长期演进(long term evolution，LTE)的MRO优化场景例如切换过早、切换过晚以及切换到错误小区三种场景之外，还引入了两种新的场景。一种新的MRO场景是应用在多链接的数据传输(multi-radio dual connectivity，MR-DC)架构下，辅基站更换过早、过晚以及更换至错误辅基站三种场景，通过收集辅基站的无线链路失败报告来解决所述三种场景；另一种新的MRO场景是在切换成功的前提下解决可能出现的“接近无线链路失败(near-RLF)”的场景。
MRO需要获取到采集网元上的数据，例如基站之间接口的信令，基站与核心网之间接口的信令等，才能确定对相关系统间切换参数进行调整，这些网元数据的采集通过无线链路信息跟踪服务(trace)根据第二网络管理节点(例如网络管理节点，核心网)等订阅需要，采集网元上的数据，并分发给第二网络管理节点。
现有技术中，trace无法获取到MR-DC和near-RLF的相关数据，也就无法供其他第二网络管理节点分析所述场景的相关问题。
因此，现有技术中存在的上述问题还有待于改进。

结合上述第二方面及第二方面任意一种可能的实现方式，在第三种可能的实现方式中，该第一消息为该第一网络管理节点从第五网络管理节点获取到的，该第五网络管理节点可以是NMS、EMS、Mns生产者(Mns Producer)、Mns消费者(Mns Consumer)或者MAE。

本申请第三方面提供一种无线链路信息分析方法，包括：第三网络管理节点从第二网络管理节点获取第一无线链路信息和/或第二无线链路信息，其中，该第一无线链路信息及该第二无线链路信息分别为第一接入设备根据第一网络管理节点发送的工作类型获取到的信息，该第一无线链路信息为终端成功进行切换时的无线链路信息；该第二无线链路信息为多链接场景下，终端与第二接入设备连接失败时的无线链路信息，在该多链接场景下，该第一接入设备与该第二接入设备对该终端构成多链接的数据传输；该第三网络管理节点对该第一无线链路信息和/或该第二无线链路信息进行分析以得到分析结果，该分析结果包括覆盖问题或移动性问题中的至少一种；可选地，第一接入设备可以为基站，第一网络管理节点可以为无线自动化的引擎(MBB automation engine，MAE)、网络管理系统(network management system，NMS)或者网元管理系统(element management system，EMS)，该工作类型可以承载在激活消息中，激活消息可以是trace session activation消息，或者也可以是新定义的消息，该第二网络管理节点可以是跟踪收集实体(trace collection entity，TCE)，该第三网络管理节点可以是MDAS Producer。

本实施例中，RLM计时器的状态用于识别下行覆盖问题，例如RLM计时器为“T310expire”，即当T310计时器期间，服务小区的信号变差时，终端可能需要切换，但由于服务小区的信号很差，导致终端收到切换命令延迟，从而导致T310超时，继而发生了RLF。因此第三网络节点可以通过该计时器超时来识别下行覆盖问题。

本实施例中，RLC重传次数可以用于识别上行覆盖问题，例如，当下行信号质量好，上行覆盖受限的时候，终端会出现上行传输问题，即上行RLC重传次数会高，从而第三网络管理节点通过分析切换成功报告中的RLC重传次数，判断上行覆盖是否发生了near-RLF问题。

本实施例中，第一接入设备将所获取到的第二无线链路信息以辅基站连接失败报告的方式发送给第二网络管理节点，并由第二网络管理节点发送给第三网络管理节点，以使得第三网络管理节点基于辅基站连接失败报告对终端与第二接入设备之间的连接失败问题进行分析。

结合上述第三方面第一或第六种可能的实现方式，在第七种可能的实现方式中，该方法还包括：该第三网络管理节点将该分析结果发送给第四网络管理节点，以使得该第四网 络管理节点根据该分析结果调整网络参数。可选地，该第四网络管理节点为MDAS Consumer。
本实施例中，第三网络管理节点用于根据第一无线链路上信息或第二无线链路信息进行分析以得到分析结果，第三网络管理节点将所得到的分析结果发送给第四网络管理节点，以使得第四网络管理节点根据该分析结果对网络参数进行调整。
结合上述第三方面第七种可能的实现方式，在第八种可能的实现方式中，该第三网络管理节点将该分析结果发送给第四网络管理节点，包括：该第三网络管理节点从该第四网络管理节点获取订阅信息，该订阅信息用于请求订阅以下信息中的至少一种：该切换成功包括或该辅基站连接失败报告中的至少一种、目标周期以及目标事件；当该订阅消息包括该切换成功报告或该连接失败报告中的至少一种时，该第三网络管理节点根据该订阅信息向该第四网络管理节点发送对该切换成功报告的分析结果，和/或，对该连接失败报告的分析结果；当该订阅消息包括该目标周期时，该第三网络管理节点每间隔该目标周期向该第四网络管理节点发送该分析结果；当该订阅消息包括该目标事件时，该第三网络管理节点在该目标事件触发时向该第四网络管理节点发送该分析结果。
本实施例中，第三网络管理节点通过订阅消息中的消息范围，知晓第四网络管理节点所期望获得的分析结果，从而第三往管理节点可以向第四网络管理节点发送切换成功报告或该辅基站连接失败报告中的至少一种。进一步地，根据目标周期和目标事件，第三网络管理节点知晓发送分析结果的时机，只通过一次订阅消息的收发，第三网络管理节点就能够向第四网络管理节点周期性地发送分析结果，从而节省了信令交互。

本实施例中，RLM计时器的状态用于识别下行覆盖问题，例如RLM计时器为“T310expire”，即当T310计时器期间，服务小区的信号变差时，终端可能需要切换，但由于服务小区的信号很差，导致终端收到切换命令延迟，从而导致T310超时，继而发生了RLF。因此可以通过该计时器超时来识别下行覆盖问题。

具体实施方式
本发明实施例提供一种无线链路信息获取、分析、指示方法、设备及介质，能够通过发送工作类型信元，解决网络管理节点无法获取指定类型数据的问题。
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本申请保护的范围。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
终端，例如用户设备(user equipment,UE)在执行小区间的切换时，不合适的切换参数引起的无线链路失败对用户体验及网络资源都有影响，对此，引入了移动性鲁棒性优化(mobility robust optimization，MRO)，MRO的目的是通过对系统间切换进行监测、识别、统计，然后确定对相关系统间切换参数进行调整以改变系统间切换的难易程度，以达到最小化系统间切换的异常，尽可能减少系统间切换性能的降低。
在5G新空口系统(new radio，NR)下，也引入了MRO优化，除了继承了长期演进(long term evolution，LTE)的MRO优化场景例如切换过早、切换过晚以及切换到错误小区三种场景之外，还引入了两种新的场景。一种新的MRO场景是应用在多链接的数据传输(multi-radio dual connectivity，MR-DC)架构下，辅基站更换过早、过晚以及更换至错误辅基站三种场景，通过收集辅基站的无线链路失败报告来解决所述三种场景；另一种新的MRO场景是在切换成功的前提下解决可能出现的“接近无线链路失败(near-RLF)”的场景。
MRO需要获取到采集网元上的数据，例如基站之间接口的信令，基站与核心网之间接口的信令等，才能确定对相关系统间切换参数进行调整，这些网元数据的采集通过无线链路信息跟踪服务(trace)根据网络管理节点(或核心网)等订阅需要，采集网元上的数据，并发送给网络管理节点。
可选地，该网络管理节点可以是一个管理数据分析的服务(management data analytics service，MDAS)，如图1所示，管理数据分析的服务MDAS包括数据分析模块analytics101，该analytics就是MDAS Producer，即MDA功能的提供者，用于根据trace所采集到的数据对无线链路情况进行分析；MDAS Consumer图中没有显示，MDAS Consumer为MDAS功能的消费者，与analytics相连接，用于根据MDAS Producer的分析结果对网元的网络参数进行调整；intelligence就是数据决策单元102，data是数据103，可以是任何数据，data collection是数据收集的功能实体104，例如跟踪收集实体(trace collection entity，TCE)，用于对基站所上报的数据进行收集，orchestration&control是执行单元105，即最终负责执行 优化的实体。
当前，trace无法获取到MR-DC和near-RLF的相关数据，也就无法供给网络管理节点分析所述场景的相关问题。
为了解决上述问题，本申请实施例提供一种无线链路信息获取、分析、指示方法、设备及介质，可用于5G空口无线网络系统(5G NG radio access network，5G NG-RAN)中，用于解决网络管理节点无法获取指定类型数据的问题。
首先，对本申请实施例所应用的系统架构场景进行说明，本申请实施例所提供的方法用于5G NG-RAN系统，还可以用于多链接数据传输架构，例如4G核心网络的多链接数据传输架构(MR-DC with EPC)，即演进型通用陆地无线接入之间的双链接(Intra-E-UTRA dual connectivity，EN-DC)架构，以及5G核心网络的多链接数据传输架构(MR-DC with 5GC)，即NG无线网络架构下的E-UTRA-NR双链接(NG-RAN E-UTRA-NR dual connectivity，NGEN-DC)架构，NR-E-UTRA双链接(NG-RAN E-UTRA-NR dual connectivity，NE-DC)架构，NR-NR双链接(NR-NR dual connectivity，NR-DC)架构等，对此本申请实施例并不进行限定。作为一种举例，请参阅图2，图1以EN-DC为例对本申请实施例所提供方法的应用场景进行介绍。
如图2所示，移动性管理实体(mobility management entity，MME)或服务网关(serving gateway，S-GW)组成了系统的核心网(evolved packet core，EPC)，en-gNB为与核心网对接的5G基站，eNB为4G基站，en-gNB和eNB组成了系统的演进型通用陆地无线接入(evolved universal terrestrial radio access，E-UTRA)。
本申请实施例的第一个应用场景为，终端向基站所在小区切换成功时，由于信号强度是波动的，有可能会发生接近无线链路失败(near radio link failure，near-RLF)。对于这种near-RLF情况，网络管理节点也需要获取到相应的无线链路数据，从而进行相应的调整。
本申请实施例的第二个应用场景为多链接的场景，eNB为主基站，en-gNB为辅基站，主基站和辅基站与终端构成多链接的数据传输(multi-radio dual connectivity，MR-DC)，当终端发生小区切换时，终端在主基站的指示下更换辅基站，此时，终端与辅基站之前可能会发生连接失败的情况，例如过早、过晚地切换辅基站，或者终端切换到了错误的辅基站。对于这些错误情况，网络管理节点需要获取到MR-DC场景下的无线链路数据，从而进行相应的调整。
本申请实施例所提供的方法用于跟踪管理架构，跟踪管理架构是用于采集终端的测量数据，跟踪管理架构中包括跟踪管理实体(TCE，Trace collection entity)，主要用于采集终端的测量数据，数据采集可以由网络管理实体触发，也可以是由管理服务提供者或者管理服务消费者触发数据的采集。
本申请实施例所提供的方法用于标准服务化管理架构，管理服务化架构包括管理服务(Management Service，MnS)和管理功能(Management Function，MnF)这两个主要概念。其中管理服务提供管理能力。管理服务消费者通过由单独指定的管理服务组件组成的标准化服务接口访问这些管理能力。管理功能是一个管理实体，其外部可见的行为和接口被标准规定为管理服务。管理服务的使用者(例如：运营商)为管理服务的消费者提供功能和 内容，以便于管理服务的消费者根据场景来决定如何使用。这里管理服务的使用者可以称之为MnS Producer，管理服务的消费者可以称之为MnS Consumer。
本申请实施例所提供的方法用于管理数据分析服务(MDAS，management data analytics management service)架构，管理数据分析服务架构是一个管理闭环，包括分析(analytics)、决策(decision)、执行(Execution)以及观测(Observation)，其中，这个管理闭环是通过采集的数据来执行的。所述管理闭环能够对外提供分析能力。其中该分析能力可以理解为MDAS Producer，即MDA功能的提供者，使用该分析结果的消费者可以理解为是MDAS Consumer。
为此，本申请实施例提供一种无线链路信息获取方法，网络管理节点通过发送工作类型指定获取数据的类型，从而解决网络管理节点无法获取指定类型数据的问题，具体应用于以下两个场景：一、终端向基站切换成功场景下的near-RLF问题。二、MR-DC场景下终端与辅基站连接失败的问题。为便于理解，以下结合说明书附图，对本申请实施例所提供的方法进行详细说明。
一、终端向基站切换成功场景下的near-RLF问题。
本实施例中，终端向基站切换成功后，由于信号强度是波动的，有可能会发生接近无线链路失败near-RLF问题，而当前网络管理节点无法获取到这个场景下网元的无线链路数据，对此，本申请实施例提供的如下技术方案，请参阅图3，如图3所示，本申请实施例所提供的无线链路信息获取方法的实施例一包括以下步骤。

该第一消息中包括工作类型job type，工作类型为切换成功报告上报，即用于指示切换成功报告的上报，也即终端成功进行切换时的测量信息的上报。例如job type为successful handover reporting或者successful handover reporting only。需要说明的是，所述Job type切换成功报告上报也可以定义为其他名称，旨在指示终端成功进行切换时的测量信息的上报，本发明在此不做限定。

本实施例中，第一消息中的全部或部分内容由第五网络管理节点生成并发送给第一网络管理节点，以使得第一网络管理节点能够获取到第一消息并发送给第一接入设备。
作为一种示例性的实施方式，为了激活一个跟踪任务(trace job)，MnS消费者在MnS生产者上创建Trace Job的对象。其中的trace job type中可以指示RLF报告、SCG failure报告上报、successful HO报告上报中的一种或多种。所述创建Trace Job的对象可以通过现有的createMOI创建操作来执行或者新定义的操作，例如，第五网络管理节点向第一网络管理节点发送create trace job，操作消息中携带trace job的相关配置，如job type等，所述配置可以在资源模型(network resource model，NRM)中定义。本发明在此不限定，相应的，对于查看、修改、删除Trace Job对象或者部分该对象中的部分属性可以通过现有的getMOIAttributes、modifyMOIAttributes、deleteMOI操作来执行，或者通过新定义的操作，本发明在此不限定。
作为另一种示例性的实施方式，在该第五网络管理节点的资源模型NRM中定义了该跟踪任务(trace job)，其中的job type可以指示RLF报告上报、SCG failure报告上报、successful HO报告上报中的一种或多种。可选的，该NRM中还可以定义上述第一消息中包括的其它信息的一种或多种，本发明在此不做限定。
302、第一接入设备收到工作类型后获取第一无线链路信息。
本实施例中，该工作类型为切换成功报告上报，第一接入设备根据所述工作类型获取切换成功报告，也即是获取第一无线链路信息。
该第一无线链路信息为终端成功进行切换时的测量信息，也即切换成功报告(successful handover report)。

从而使得第二网络管理节点获取到了终端向第一接入设备切换成功场景下的第一无线链路信息，第三网络管理节点可以根据该第一无线链路信息分析哪些位置/区域有near-RLF的问题，或者，根据终端的时间信息确定在哪个时间或者时间段上出现了near-RLF的问题，进一步地，第三网络管理节点所输出的分析结果可以进一步的给其他实体来应用。分析结果可以具体到移动性问题还是覆盖问题，还可以是具体调整的参数的建议。
需要说明的是，所述第二网络管理节点和第三网络管理节点可以是同一个节点，或者也可以是不同的节点，本发明在此不做限定。
本实施例中，第一网络管理节点向第一接入设备发送工作类型，该工作类型用于指示切换成功报告的上报，从而使得第一接入设备向第二网络管理节点发送第一无线链路信息。通过此种方式，第一接入设备将所获取到的第一无线链路信息发送给第二网络管理节点，由第二网络管理节点转发给第三网络管理节点，使得第三网络管理节点能够获取到终端成功进行小区切换时的无线链路信息。
需要说明的是，在终端成功进行切换时，切换成功报告可以包括不同的切换阶段的测量数据，例如切换触发阶段、切换执行阶段和切换执行完成阶段，其中，切换触发阶段可以是在终端收到切换命令后收集的数据，切换执行阶段可以是终端向第一接入设备发起随 机接入过程产生的相关数据，切换执行完成阶段可以是终端向第一接入设备发送切换完成消息后产生的相关数据，对此本申请实施例并不进行限定。
需要说明的是，终端虽然切换成功了，但在上述阶段中，均有可能发生濒临无线链路失败(例如near-RLF)问题。因此，第三网络管理节点需要对上述阶段的第一无线链路信息进行分析，从而判断不同阶段的near-RLF问题。第三网络管理节点为了进一步细化地定位near-RLF的产生原因，需要获取更细粒度的切换成功报告。对此，本申请实施例提供了一种更优选地实施方式，以解决此问题。为便于理解，以下结合附图进行详细说明。

503、第一接入设备向第二网络管理节点发送第二无线链路信息。

需要说明的是，所述第二网络管理节点和第三网络管理节点可以是同一个节点，或者也可以是不同的节点，本发明在此不做限定。
本实施例中，第一网络管理节点向第一接入设备发送工作类型，该工作类型用于指示辅基站连接失败报告的上报，从而使得第一接入设备向第二网络管理节点发送第二无线链路信息。通过此种方式，第一接入设备将所获取到的第二无线链路信息发送给第二网络管理节点，由第二网络管理节点转发给第三网络管理节点，使得第三网络管理节点能够获取到终端与辅基站连接失败时的无线链路信息。
进一步地，当第三网络管理节点按照上述方法获取到无线链路数据后，需要对所获取到的数据进行分析，具体地，在上述第一种应用场景下分析终端与基站之间的near-RLF问题，在第二种应用场景下分析终端与第二接入设备之间的连接失败问题。对于第三网络节点所得到的分析结果，可以进一步发送给第四网络节点，以使得第四网络管理节点可以根据分析结果，对网络参数进行调整，以使得通讯系统可以正常的工作。对此，本申请实施例提供一种无线链路信息分析方法，分别针对上述第一种应用场景：终端向基站切换成功场景下的near-RLF问题，以及上述第二种应用场景：MR-DC场景下终端与辅基站连接失败的问题。为便于理解，以下结合附图，分别对这两种应用场景下的分析方法进行详细说明。
一、终端向基站切换成功场景下的near-RLF问题分析方法。
本实施例中，在终端向基站切换成功场景下发生near-RLF问题时，按照上述方法，第 三网络管理节点获取到了第一无线链路信息，并对其进行分析，将得到的分析结果发送给第四网络管理节点，进一步地，由第四网络管理节点来对终端和基站的网络参数进行调整。为便于理解，以下结合附图对此种情况进行详细说明，请参阅图6，如图6所示，本申请的实施例四包括以下步骤。
601、第三网络管理节点从第二网络管理节点获取第一无线链路信息。
本实施例中，第三网络管理节点从第二网络管理节点获取切换成功报告，切换成功报告中包括第一无线链路信息，或者，该切换成功报告就是第一无线链路信息。第一无线链路信息为成功进行小区切换时的信息。该第一无线链路信息的具体信息可参阅上述步骤302中的相关记载，此处不再赘述。第三网络管理节点获取第一无线链路信息的具体实现方式可以参照上述实施例一或实施例二中的任意一种，此处不再赘述。
602、第三网络管理节点根据第一无线链路信息获取分析结果。
本实施例中，例如，第三网络管理节点可以是MDAS Producer，第三网络管理节点对获取到的第一无线链路信息进行分析，从而了解第一接入设备对终端的覆盖问题和/或移动性问题。
可选地，第一无线链路信息被记录在切换成功报告中，第三网络管理节点获取第二网络管理节点发送的切换成功报告，并对切换成功报告进行分析从而得到分析结果。
可选地，切换成功报告中记录有至少一种测量信息，这些测量信息用于记录终端与第一接入设备之间的连接情况，其中，测量信息可以包括无线链路监控信息(radio link monitoring,RLM)及无线链路控制(radio link control，RLC)重传次数中的至少一种。以下针对这两种数据的具体分析方法进行详细说明。
1、切换成功报告中包括RLM信息。
第三网络管理节点对于切换成功报告中记录的RLM信息进行分析，包括以下步骤。
1)、第三网络管理节点获取RLM中的计时器记录的终端向第一接入设备的切换时间。
2)、第三网络管理节点判断该切换时间是否大于预设值，其中，该预设值可以由本领域技术人员根据实际情况进行预设，对此本申请实施例并不进行限定。
3)、当该切换时间对于预设值时，第三网络管理节点判断第一接入设备与终端之间发生接近无线链路失败near-RLF，下行覆盖异常。
本实施例中，RLM计时器的状态用于识别下行覆盖问题，例如RLM计时器为“T310expire”，即当T310计时器期间，服务小区的信号变差时，终端可能需要切换，但由于服务小区的信号很差，导致终端收到切换命令延迟，从而导致T310超时，继而发生了RLF。因此该计时器超时可以用来识别下行覆盖问题。
2、切换成功报告中包括RLC重传次数。
第三网络管理节点对于切换成功报告中记录的RLC重传次数进行分析，包括以下步骤。
1)、第三网络管理节点从切换成功报告中获取RLC重传次数。
2)、第三网络管理节点判断该RLC重传次数是否大于预设值，其中，该RLC重传次数可以由本领域技术人员根据实际情况进行预设，对此本申请实施例并不进行限定。
3)、当该RLC重传次数大于预设值时，第三网络管理节点判断第一接入设备与终端之间发生上行覆盖受限。
本实施例中，RLC重传次数可以用于识别上行覆盖问题，例如，当下行信号质量好，上行覆盖受限的时候，终端会出现上行传输问题，即上行RLC重传次数会高，从而第三网络管理节点通过分析切换成功报告中的RLC重传次数，判断上行覆盖是否发生了near-RLF问题。
进一步地，切换成功报告中的测量信息还可以包括波束失败检测信息BFD、参考信号接收质量信息RSRQ、小区或波束测量信息及终端获取切换成功报告时所对应的时间信息和位置信息中的至少一种，第三网络管理节点根据这些数据对near-RLF问题进行分析的方法属于现有技术，对此本申请实施例不再赘述，同时，切换成功报告中还可以包括其他类型的无线链路信息，对此本申请实施例并不进行限定。
更进一步地，如上述实施例二所述，切换成功报告中还可以包括目标阶段，这些目标阶段为终端向第一接入设备的切换触发阶段、切换执行阶段或切换执行完成阶段中的至少一个数据阶段，此时，上述测量信息，就是这些目标阶段中所获取到的测量信息。则第三网络管理节点可以更加细化地分析不同数据阶段的near-RLF问题，例如第三网络管理节点根据终端向第一接入设备切换触发阶段的RLM信息，分析切换触发阶段的下行覆盖是否发生了near-RLF问题，或者，第三网络管理节点根据终端向第一接入设备切换执行阶段的RLC重传次数，分析切换执行阶段的上行覆盖是否发生了near-RLF问题，从而细化了问题分析的粒度，能够精确地判别near-RLF问题发生在哪个数据阶段。
可选地，上述数据阶段中所包括的目标阶段，还可以根据实际需求，以其他的粒度进行区分，例如不同的粒度，或者更细化的粒度，对此本申请实施例并不进行限定。
本实施例中，由于第一无线链路信息是通过本申请实施例一或实施例二所提供的方法获取到的，从而第三网络管理节点能够根据所获取到的第一无线链路信息，对终端与接入设备之间的near-RLF问题进行分析，从而使得第二网络管理节点能够判断终端与第一接入设备之间是否发生了near-RLF问题。
603、第三网络管理节点将分析结果发送给第四网络管理节点。
本实施例中，第四网络管理节点可以是无线自动化的引擎(MBB automation engine，MAE)、网络管理系统(network management system，NMS)、网元管理系统(element management system，EMS)、Mns生产者(Mns Producer)、Mns消费者(Mns Consumer)、MDAS生产者(MDAS Producer)或者MDAS消费者(MDAS Consumer)，对此，本申请实施例并不进行限定。为便于理解，本实施例中以第四网络管理节点为MDAS Consumer对方案进行说明，但是并不构成对本申请实施例的限定，如上所述，第三网络管理节点为MDAS Producer，MDAS Consumer用于根据MDAS Producer的分析结果调整网络参数，从而修复终端与第一接入设备之间的near-RLF问题。
可选地，第三网络管理节点向第四网络管理节点发送分析结果的方式，可以分为两种不同的方式，1、第三网络管理节点根据第四网络管理节点发送的订阅信息主动向第四网络管理节点发送分析结果。2、第三网络管理节点根据第四网络管理节点发送的请求消息向第四网络管理节点发送分析结果。为便于理解，以下分别结合附图，对此两种情况进行详细的说明。
1、第三网络管理节点根据第四网络管理节点发送的订阅消息向第四网络管理节点发送 分析结果。
本实施例中，第四网络管理节点向第三网络管理节点发送订阅消息，例如，通过现有的subscribe操作消息，或者新定义的操作消息，本发明在此不做限定。订阅消息可以包括：1)、消息范围、2)、目标周期以及3)、目标事件中的至少一种，以使得第三网络管理节点每间隔目标周期和/或目标事件触发时，向第四网络管理节点发送其所订阅的全部或部分第一无线链路信息。以下分别结合附图对此三种情况进行详细说明。
1)、订阅消息中包括消息范围。
本实施例中，订阅信息的消息范围用于指定第四网络管理节点所期望获得的消息，例如，订阅消息用于订阅以下消息中的一种或多种。
a、终端切换成功的场景下，对于near-RLF问题的分析结果(对于切换成功报告的分析结果)。可选地，当切换成功报告中包括多个不同的数据阶段时，订阅消息还可以请求订阅其中一个或多个数据阶段中对于near-RLF问题的分析结果。
b、多链接场景下，终端与第二接入设备(例如，辅基站)连接失败时的分析结果(对于辅基站连接失败报告的分析结果)。
c、无线链路失败时的分析结果(对无线链路失败报告RLF report的分析结果，需要说明的是，RLF report为现有技术中的报告类型，用于记录终端与第一接入设备之间的连接状态，例如，用于识别终端的切换过早、过晚、切换到错误小区等场景；以及，识别基站的覆盖情况，弱覆盖、覆盖漏洞、越区覆盖等)。
需要说明的是，上述b情况适用于多链接场景下，终端与辅基站(或辅小区组secondary cellgroup，SCG)之间的连接失败报告SCG failure report；而上述c情况用于终端与基站之间的无线链路失败(radio link failure，RLF)的连接失败报告RLF report，是一种通用的场景，因此两种连接失败报告并不相同。现有技术中的方案，第二网络管理节点能够获取到连接失败报告RLF report，而第二网络管理节点必须依靠本申请实施例所提供的无线链路信息获取方法，才能获取到辅基站连接失败报告SCG failure report。
请参阅图7，如图7所示，此种情况具体包括如下步骤。
701、第四网络管理节点向第三网络管理节点发送第一订阅信息。
本实施例中，第一订阅信息用于请求订阅第三网络管理节点的部分分析结果或全部分析结果，其中，部分分析结果为第一订阅信息指定部分的分析结果，例如可以是上述a、b及c所述分析结果中的至少一种。
702、第三网络管理节点根据第一订阅信息向第四网络管理节点发送部分分析结果或全部分析结果。
本实施例中，第三网络管理节点根据第一订阅信息的指示，向第四网络管理节点发送其所期望的信息。
本实施例中，第四网络管理节点通过第一订阅消息，使得第三网络管理节点知晓需要发送哪些分析结果，从而第四网络管理节点可以获取到自身所期望的分析结果。
2)、订阅信息中包括目标周期。
本实施例中，可选的，第四网络管理节点向第三网络管理节点发送目标周期，以使得第三网络管理节点根据目标周期向第四网络管理节点发送分析结果。请参阅图8，如图8所 示，具体包括以下步骤。
801、第四网络管理节点向第三网络管理节点发送第二订阅信息。
本实施例中，第二订阅信息包括目标周期，该目标周期可以是由标准定义的，也可以是由第四网络管理节点指定的，对此本申请实施例并不进行限定。通过该第二订阅信息中携带的目标周期，第三网络管理节点可以知晓向第四网络管理节点发送分析结果的周期。
802、第三网络管理节点每间隔目标周期向第四网络管理节点发送分析结果。
本实施例中，第三网络管理节点根据第四网络管理节点所订阅的目标周期，向其发送分析结果，可选地，第三网络管理节点所发送的分析结果可以是第三网络管理节点中的全部分析结果，也可以按照图7中所示的步骤，发送部分分析结果，对此本申请实施例并不进行限定，第四网络管理节点向第三网络管理节点指示部分分析结果的具体步骤可参阅上述图7所示的步骤，此处不再赘述。
本实施例中，由于终端和基站之间的连接情况是动态变化的，第三网络管理节点需要实时地对覆盖情况和移动情况进行分析，之后按照第四网络管理节点所指示的目标周期，周期性地向第四网络管理节点发送分析结果，只通过一次订阅消息的收发，第三网络管理节点就能够向第四网络管理节点周期性地发送分析结果，从而节省了信令交互，当第三网络管理节点需要对目标周期进行调整时，可以重复上述图8所示的步骤，更新目标周期。
3)、订阅信息中包括目标事件。
本实施例中，第三网络管理节点根据第四网络管理节点所订阅的目标事件，在目标事件触发时向第四网络管理节点发送目标事件。请参阅图9，如图9所示，此种情况包括以下步骤。
901、第四网络管理节点向第三网络管理节点发送第三订阅信息。
本实施例中，第三订阅信息包括目标事件，以使得第三网络管理节点在满足目标事件时向第四网络管理节点发送分析结果，所述目标事件可以是通过设置阈值来实现，例如，分析结果覆盖问题超出百分之X就需要上报分析结果，X可以由本领域技术人员根据实际需要设定，本发明在此不限定。
902、当目标事件触发时，第三网络管理节点向第四网络管理节点发送分析结果。
本实施例中，根据第四网络管理节点发送的目标事件，当目标事件触发时，第三网络管理节点向第四网络管理节点发送分析结果，可选地，第三网络管理节点所发送的分析结果可以是第三网络管理节点中的全部分析结果，也可以按照图7中所示的步骤，发送部分分析结果，对此本申请实施例并不进行限定，第四网络管理节点向第三网络管理节点指示部分分析结果的具体步骤可参阅上述图7所示的步骤，此处不再赘述。
本实施例中，根据第四网络管理节点所订阅的目标事件，当目标事件触发时，第三网络管理节点向第四网络管理节点发送分析结果。从而进一步减少了两个网络管理节点之间的信令交互，提升了分析结果的发送效率。
可选地，第四网络管理节点通过订阅消息向第三网络管理节点订阅分析结果之后，第四网络管理节点还可以向第三网络管理节点发送取消订阅消息，从而取消第四网络管理节点对第三网络管理节点的消息订阅。
2、第三网络管理节点根据第四网络管理节点发送的请求消息向第四网络管理节点发送 分析结果。
本实施例中，当第四网络管理节点需要从第三网络管理节点获取分析结果时，向第三网络管理节点发送请求消息，以使得第三网络管理节点根据请求消息向第四网络管理节点发送分析结果，这种基于请求上报分析结果的方式，使得第四网络管理节点能够随时根据请求消息获取到第三网络管理节点的分析结果，具有更好的机动性。为便于理解，以下结合附图对此种情况进行详细说明。
请参阅图10，如图10所示，此种情况包括以下步骤。
1001、第四网络管理节点向第三网络管理节点发送请求消息。
本实施例中，请求消息用于请求第三网络管理节点的分析结果，可选地，该请求消息中也可以携带有指示信息，指示第三网络管理节点中的部分分析结果，例如near-RLF场景下的切换成功报告，多链接场景下的辅基站连接失败报告以及无线链路失败报告，对此本申请实施例并不进行限定。
1002、第三网络管理节点根据请求消息向第四网络管理节点发送分析结果。
本实施例中，第三网络管理节点根据请求消息的请求，向第四网络管理节点发送分析结果，从而实现了基于请求消息的发送。
本实施例中，相较于通过订阅消息订阅分析结果的方式，第四网络管理节点在需要获取分析结果时直接向第三网络管理节点发送请求消息，即可实时获取到第三网络管理节点的分析结果。
