本申请涉及无线通信技术领域，具体而言，本申请涉及无线通信方法、用户设备、电子设备及存储介质。
背景技术
移动健壮性优化(Mobility Robustness Optimisation，MRO)技术通过分析无线链路失败(Radio Link Failur，RLF)报告优化切换参数配置，解决切换过程中发生的RLF或者切换失败。
第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)在R16版本中增加了接入共享频谱网络的功能，在R17版本中增加了对接入共享频谱网络进行MRO(移动健壮性优化)的特性。由于传统网络和共享频谱网络的差异，特别是共享频谱网络可能发生LBT失败。
现有的MRO技术主要针对非共享频谱网络进行参数优化，但是在共享频段网络场景下，根据RLF报告中记载的内容无法准确定位导致无线链路失败的原因，进而影响参数优化结果，甚至导致参数优化发生错误。

具体实施方式
下面详细描述本申请的实施例，实施例的示例在附图中示出，其中自始至终相同 或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能解释为对本申请的限制。
本技术领域技术人员可以理解，除非特意声明，这里使用的单数形式“一”、“一个”和“该”也可包括复数形式。应该进一步理解的是，本申请的说明书中使用的措辞“包括”是指存在特征、整数、步骤、操作、元件和/或组件，但是并不排除存在或添加一个或多个其他特征、整数、步骤、操作、元件、组件和/或它们的组。应该理解，当我们称元件被“连接”或“耦接”到另一元件时，它可以直接连接或耦接到其他元件，或者也可以存在中间元件。此外，这里使用的“连接”或“耦接”可以包括无线连接或无线耦接。这里使用的措辞“和/或”包括一个或更多个相关联的列出项的全部或任一单元和全部组合。
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
首先对本申请涉及的几个名词进行介绍和解释：
(1)共享频谱网络，与传统网络中多个小区分别使用专用频谱不同，在共享频谱网络中，频谱信息被多个网络的不同小区使用。也就是说，共享频谱可能被多个网络共同使用，因此基站和UE在共享频谱网络中进行数据传输之前，可能需要进行先听后说(listen before talk，LBT)过程，用来确认共享频谱是否被其他小区占用了，只有信道空闲时，才可以使用。
(2)用户设备(User Equipment，UE)进行LBT是以带宽部分(Bandwidth Part，BWP)为基础。如果网络给UE在一个小区内配置了多个BWP的随机接入资源，当UE在特殊小区(special Cell，SpCell)上连续进行LBT失败，UE将切换到其他的BWP上继续进行LBT。SpCell小区包括主小区(Primary Cell，PCell)与主辅小区(Primary Secondary Cell，PSCell)。
(3)接收信号强度指示(Received Signal Strength Indicator，RSSI)常常被高层用来评估共享频率的目标小区是否被其他网络占用，在切换触发阶段网络会参考目标小区的RSSI测量结果，选择空闲的目标小区进行接入。
(4)RLF报告
RLF报告是UE侧记录的一种报告，主要涵盖两种记录场景：切换失败及无线链路失败，一次RLF报告只能表示一种场景的记录。
RLF报告包含如下至少一项内容：UE上一个服务小区的测量结果；UE确认切换失败或无线链路失败后邻小区测量结果；UE位置信息；UE失败小区标识信息，如全球小区标识码(Cell Global Identity，CGI)或者物理小区标识(Physical Cell Identity，PCI)与频点；UE重建立小区标识信息；UE上报定时器：UE上一次确认接收切换发起消息到连接失败经历的时长；连接失败原因：切换失败或者无线链路失败；UE连接失败时使用的小区无线网络临时标识(Cell-RadioNetworkTemporaryIdentifier，C- RNTI)；无线链路失败子原因，T310超时或随机接入问题或者无线链路控制子层结构(RadioLinkControlstructure，RLC)层达到最大重传或者波束恢复失败(Beam Failure Recovery Failure，BFRF)；UE确认连接失败后到UE上报该RLF报告经历的时长；连接失败小区的跟踪区域标识(Tracking Area Code，TAC)；蓝牙(Blue Tooth，BT)相关记录结果；无线局域网(Wireless Local Area Network，WLAN)。
UE记录了RLF报告后，通过在无线资源控制层(Radio Resource Control，RRC)连接建立完成，RRC连接重配置完成，RRC连接重建立完成或者RRC恢复完成消息中通知网络侧获取。网络侧发送UE信息请求消息给UE，UE通过UE信息响应消息发送RLF报告给网络。
(5)MRO
主要解决UE移动性过程中的失败问题，辅助网络优化。UE在发生切换失败或者RLF的情况下，会记录RLF报告。UE在切换失败后进行小区选择，再通过RRC连接重建立或者RRC连接建立重新接入网络，并通知网络在UE侧保留了RLF报告，网络侧在需要时向UE获取，用于网络侧的网络优化。
MRO特性主要用于发现和解决移动性过程中参数配置问题，并定义了3种失败类型：切换过早，切换过迟，切换到错误小区。
切换过迟：UE在源小区稳定驻留一段时间后，发生了无线链路失败，UE通过RRC连接重建立试图接入一个不同的小区。
切换过早：在切换过程中UE接入目标小区失败，或者接入目标小区成功但是很快发生了无线链路失败，UE发生RRC连接重建立试图接入源小区。
切换到错误小区：在切换过程中UE接入目标小区失败，或者接入目标小区成功但是很快发生了无线链路失败，UE发生RRC连接重建立试图接入不同于切换目标小区和源小区的其他小区。
在切换完成后，UE是否可以稳定驻留在目标小区是上述失败类型判断的关键。如果稳定驻留，再发生失败就和前一次切换没有关系，如果没有稳定驻留，可能为前一次切换导致，例如目标小区选择不合理等。
终端是否稳定驻留的判断，使用RLF报告中的UE上报定时器判断，如果为该值比较小，说明没有稳定驻留，如果比较大，说明切换后稳定驻留了。如果为0，说明没有切换发生。
(6)随机接入报告
现有的随机接入报告只包含成功随机接入的相关信息。
(7)切换成功报告
切换成功报告为UE记录的在切换过程中的信息，虽然切换成功了，但在切换过程中可能存在一些临界成功或者临界失败的信息，UE记录在切换成功报告后辅助网络进行切换参数的优化。
UE记录了随机接入报告或者切换成功报告后，通过在RRC连接建立完成，RRC连接重配置完成，RRC连接重建立完成或者RRC恢复完成消息中通知网络侧获取。网络侧发送UE信息请求消息给UE，UE通过UE信息响应消息发送随机接入报告和/或者切换成功报告给网络。
MRO通过分析RLF报告优化切换参数配置，解决切换过程中发生的RLF或者切换失败，但是在共享频段网络中，由于新接入一个共享频段网络需要先进行LBT过程，LBT失败的信息当前没有记录到RLF报告中，导致在进行参数优化分析时，无法区分失败是由于切换参数配置不合适导致还是LBT失败导致，将导致错误的参数优化结果。
本申请提供的无线通信方法、装置、电子设备和计算机可读存储介质，至少解决现有技术的如上技术问题。
下面以具体实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本申请的实施例进行描述。

在一个实施例中，UE向源小区的基站(也称之为源基站)发送测量报告信息，源基站根据测量报告信息判断UE是否启动切换操作，即由源小区切换至共享频谱网络中的第一目标小区，若判断启动切换操作，则向UE发送目标指令，UE根据目标指令，确定执行由源小区切换至共享频谱网络中的第一目标小区。
在一个实施例中，本申请实施例的第一目标小区为PCell小区。
在一个实施例中，UE在切换至共享频谱网络的过程需要进行LBT。
UE由源小区切换至第一目标小区的切换结果可能是切换失败，也可能是切换成功。当切换失败时，可能意味UE在所有BWP上连续进行LBT失败，当切换成功时，也可能出现在切换过程中，UE在至少一个BWP上连续进行连续LBT失败。
应当理解的是，本申请的连续LBT失败是指连续预设次数发生LBT失败，本申请对于预设次数不作具体的限定，例如可以为3次。在本申请实施例，只要UE在BWP上发生LBT失败，都会在无线链路失败RLF报告、随机接入报告以及切换成功报告中的至少一种报告中记录LBT失败的信息。
在一个实施例中，当切换失败时，本申请实施例可以在RLF报告和/或随机接入报告中记录LBT失败的信息，当切换成功时，本申请实施例可以在RLF报告、随机接入报告以及切换成功报告中的至少一种报告中记录LBT失败的信息。
在本申请实施例中，LBT失败的信息，可以是指示因连续LBT失败导致切换失败的信息和在BWP上连续LBT失败的随机接入信息等等。
在现有技术中，UE并不会在RLF报告、随机接入报告或者切换成功报告中记录LBT失败信息，因此基站没有相关的途径从UE处获得这些信息，导致基站在判决导致失败的原因时并不准确。然而，在本申请实施例中，通过在RLF报告、随机接入报告以及切换成功报告等基站可获取到的报告中增加LBT失败信息，辅助基站判决导致失败的原因是切换配置不合适还是LBT失败，并分析出切换失败或RLF的确切原因，从而获得准确的参数优化结果，实现共享频谱网络的MRO功能。
图3示例性地示出了相关技术的UE切换至错误小区的场景下的交互过程的示意图。如图3所示，该过程可以包括：
步骤S30：UE向源基站上报测量报告，源基站根据测量报告触发UE执行基站切换；
步骤S31：UE确定执行从源基站到共享频谱网络的目标基站(即目标小区对应的基站)的切换；
步骤S32：由于目标小区为共享频谱网络，UE在接入目标小区过程中需要执行LBT，但出现连续LBT失败；
步骤S33：由于连续LBT失败，UE切换随机接入失败；
步骤S34：UE记录RLF报告，该RLF报告中没有记录LBT失败的信息；
步骤S35：UE重建立到其他基站，其他基站获取到UE记录的RLF报告；
步骤S36：其他基站将RLF报告发送给源基站进行切换失败分析；
步骤S37，源基站直接优化切换参数配置，降低其他小区的切换触发门限。
图3所示的交互场景即为典型的切换至错误小区的失败类型，即在切换过程中终端接入目标小区失败，终端发生RRC连接重建立试图接入不同于切换目标小区和源小区的其他小区。
在相关技术中，由于RLF报告中并未记录因连续LBT失败导致的结果信息，因此源基站通常直接优化切换参数配置，降低其他小区的切换触发门限(例如：降低触发信号电平等)，提高当前目标小区的切换触发门限，以使UE更容易切换到其他小区。但实际上，当目标小区为共享频谱网络时，并且由于连续LBT失败而导致切换失败，根本原因可能是共享频谱被其他小区占用，这就使得相关技术中的基站提高当前目标小区的切换触发门限的实际效果可能并不理想。
在本申请实施例中，当切换结果为切换失败时，在RLF报告中记录第一结果信息，该第一结果信息为因在所有BWP上连续LBT失败导致切换失败，使得源基站在获取UE的RLF报告后，根据第一结果信息分析出共享频谱被其他小区占用，不需要调整切换触发门限，并确定出更合理的处理方式。
在上述各实施例的基础上，作为一种可选实施例，第一结果信息通过第一指定标识信息的方式记录在所述RLF报告中。
在本申请实施例中，可以在RLF报告中新增一个标识位，以第一指定标识信息的方式记录表示因UE在所有BWP上连续LBT失败导致切换失败的标识信息，使得基站可以根据该标识位获知出切换失败的真实原因，进而给出更准确合理的处理方式，例如关注是否被其他网络占用，以及根据本申请实施例新增的服务小区和邻小区测量结果中的占用标识，判断选择合适的切换目标小区。
图4示例性地示出了本申请实施例的UE切换至错误小区的场景下的交互过程的示意图。如图4所示，该过程可以包括：
步骤S40：UE向源基站上报测量报告，源基站根据测量报告触发UE执行基站切换；
步骤S41：UE确定执行从源基站到共享频谱网络的目标基站(即目标小区对应的基站)的切换；
步骤S42：由于目标小区为共享频谱网络，UE在接入目标小区过程中需要执行LBT，但出现连续LBT失败；
步骤S43：由于UE在所有BWP上都连续LBT失败，UE切换随机接入失败；
步骤S44：UE记录RLF报告，该RLF报告记录用于表示因UE在所有BWP上连续LBT失败导致切换失败的标识信息；
步骤S45：UE重建立到其他基站，其他基站获取到UE记录的RLF报告；
步骤S46：其他基站将RLF报告发送给源基站进行切换失败分析；
步骤S47，源基站根据RLF报告中记录的上述标识信息，获得准确的参数优化结果。
在本申请实施例中，除了以第一指定标识信息的方式记录切换失败是由于在所有BWP上连续LBT失败的信息，还可以在RLF报告的随机接入信息记录内容中增加UE在所有BWP上LBT失败的随机接入信息，源基站根据UE采集的在所有BWP上LBT失败的随机接入过程中的信息，能够更准确地优化切换参数配置。
具体的，在本申请实施例中，在记录随机接入信息时可以采用列表结构，列表结构中的一个节点为一次随机接入信息，本申请实施例的随机接入信息可以包括以下至少一种：每次随机接入过程中使用的随机接入信道RACH频率资源；每次随机接入过程中涉及的同步信号块SSB、下行参考信号索引CSI-RS index及在所述SSB、CSI-RS index发送的随机接入尝试Preambles次数信息中的至少一种；每次随机接入过程的各随机接入尝试过程中的小区信号质量是否高于SSB阈值的指示信息及所述各随机接入尝试过程中是否检测到竞争随机接入过程的指示信息；两步2-step随机接入每次尝试是否回退到四步4-step随机接入的指示信息；进行2-step随机接入过程之前测量的小区信号质量；每次随机接入前进行LBT过程，是否发生了连续LBT失败的标识信息。
在接入目标小区过程中，多次随机接入尝试中发生了LBT失败的次数，可以包括以下至少一种：每个波束下发生的LBT失败的次数；全部波束下发生的LBT失败的总次数。
当记录每个波束下发生的LBT失败的次数时，可以以序列的方式进行记录，即，序列中的每个元素用于表征相应波束下发生的LBT失败的次数。当记录全部波束下发送的LBT失败的总次数时，该总次数是对所有波束下发生的LBT失败的次数的汇总后的结果。
若共享频谱被其他小区占用导致无法接入，还需要进一步确定适合接入的目标小区。一般地，可以考虑邻小区测量结果，判断邻小区是否有小区信号质量满足预设的要求，还可以考虑切换源小区是否适合继续为UE服务，但目前的源小区和邻小区的测量结果并不能准确分析出共享频谱是否空闲。
因此，为了解决该技术问题，作为一种可选实施例，在本申请实施例中，在RLF报告、随机接入报告以及切换成功报告中的至少一种报告中记录以下至少一种信息：源小区和邻小区的RSSI测量结果，单位为分贝毫瓦(decibel relative to one milliwatt，dbm)；源小区和邻小区的用于记录信道是否被占用的标识信息。
通过在报告中增加记录信道是否被占用的标识信息，能够快速判断共享频谱是否空闲，提高分析效率。
图5示例性地示出了相关技术的UE切换临界失败场景下的交互过程的示意图。 如图5所示，该过程可以包括：
步骤S50：UE向源基站上报测量报告，源基站根据测量报告触发UE执行基站切换；
步骤S51：UE确定执行从源基站到共享频谱网络的目标基站的切换；
步骤S52：UE在接入目标小区过程中发生了LBT失败；
步骤S53：UE在进行多次随机接入尝试后，若LBT成功，随机接入成功；
步骤S54：UE记录随机接入报告，该报告中包括LBT成功的随机接入信息；
步骤S55：基站侧获取随机接入报告，但因仅包括LBT成功的随机接入信息，在下次进行BWP分配时可能还会选择到LBT失败的BWP。
UE在共享频段的随机接入过程中，若在一个BWP连续LBT失败后，可以更换BWP后继续进行LBT，但是现有随机接入报告只能记录成功的随机接入信息，也就是说，随机接入报告不能记录曾经发生过的在某些BWP上的连续的LBT失败。基站侧在分析随机接入报告时无法得知某些BWP上可能存在和其他网络冲突的情况，在下次进行资源分配时可能还会选择到这些资源，可能导致切换时延增加，切换失败率增加。
为了解决上述问题，在本申请实施例中，在无线链路失败RLF报告、随机接入报告以及切换成功报告中的至少一种报告中记录LBT失败信息，包括：若切换结果为切换成功，则在所述RLF报告、随机接入报告以及切换成功报告中的至少一种报告中记录第二结果信息，所述第二结果信息为在切换成功前的至少一个BWP上LBT失败的随机接入信息。
图6示例性地示出了本申请实施例的切换临界失败场景下的交互过程的示意图。如图6所示，该过程可以包括：
步骤S60：UE向源基站上报测量报告，源基站根据测量报告触发UE执行基站切换；
步骤S61：UE确定执行从源基站到共享频谱网络的目标基站的切换；
步骤S62：UE接入目标小区过程中发生了LBT失败；
步骤S63：UE进行多次随机接入尝试后，若LBT成功，随机接入成功；
步骤S64：UE记录随机接入报告，该报告中包括在切换成功前的至少一个BWP上连续LBT失败的随机接入信息；
步骤S65：基站侧获取随机接入报告，根据连续LBT失败的随机接入信息，在下次进行BWP分配时规避连续LBT失败的BWP。
在上述各实施例的基础上，在本申请实施例中，在记录UE在至少一个BWP上LBT失败的随机接入信息时，可以使用列表结构，列表中的一个节点即为依次随机接入的信息，可以包括：
每次随机接入过程中使用的随机接入信道RACH频率资源；
每次随机接入过程中涉及的同步信号块SSB、下行参考信号索引CSI-RS index及在SSB、CSI-RS index发送的随机接入尝试Preambles次数信息中的至少一种；
每次随机接入过程的各随机接入尝试过程中的小区信号质量是否高于SSB阈值的指示信息及所述各随机接入尝试过程中是否检测到竞争随机接入过程的指示信息；
2-step随机接入每次尝试是否回退到4-step随机接入的指示信息；
进行2-step随机接入过程之前测量的小区信号质量；
每次随机接入前进行LBT的过程中，是否发生了连续LBT失败的标识信息；
在接入目标小区过程中，进行多次随机接入尝试发生LBT失败的次数。
若切换结果为切换成功，则在所述RLF报告、随机接入报告以及切换成功报告中的至少一种报告中记录第二结果信息，所述第二结果信息为在切换成功前的至少一个BWP上LBT失败的随机接入信息。
在上述各实施例的基础上，作为一种可选实施例，在切换临界失败的情况下，也可以在RLF报告、随机接入报告以及切换成功报告中的至少一种报告中记录源小区和邻小区的RSSI测量结果、源小区和邻小区的用于记录信道是否被占用的标识信息，从而辅助基站选择更合适的切换目标小区。
图7示例性地示出了相关技术的过早切换场景下的交互过程的示意图。如图7所示，该过程可以包括：
步骤S70：UE向源基站上报测量报告，源基站根据测量报告触发UE执行基站切换；
步骤S71：UE确定执行从源基站到共享频谱网络的目标基站的切换；
步骤S72：UE切换失败；
步骤S73：UE记录RLF报告，未记录LBT失败的信息，例如因UE在所有BWP上连续LBT失败导致切换失败的标识信息；
步骤S74：UE尝试重建立到源基站，在RLF报告中未记录表示未发出无线资源控制RRC连接重建立请求的信息；
步骤S75：UE在其他基站重新接入网络，其他基站获取到UE记录的RLF报告；
步骤S76：其他基站将RLF报告发送给源基站进行切换失败分析；
步骤S77：源基站在进行MRO统计时出现漏统计或者重复统计。
上述流程为典型的切换过早失败的场景，也就是在切换过程中终端接入目标小区失败，终端发生RRC连接重建立试图接入源小区。在相关技术中，RLF报告中包括终端重建立小区标识信息，用于记录UE在切换失败后发生重建立试图接入源基站小区的标识信息。
但是如果发生RRC连接重建立的小区为共享频谱网络，有可能由于在所有的BWP上连续LBT失败，导致UE无法将RRC连接重建立请求发送给基站。之所以无法将请求发送至基站，是由于共享频谱被其他小区占用，UE没有机会发送RRC连接 重建立请求消息，应该在RLF报告中进行记录，避免基站在进行MRO统计时出现漏统计或者重复统计。
因此，在上述各实施例的基础上，作为一种可选实施例，在RLF报告中记录第一结果信息之后，无线通信方法还可以包括：触发无线资源控制RRC连接重建立至共享频谱网络中的第二目标小区，进行LBT；当UE切换至第一目标小区失败后，即可触发RRC重连接至其他小区，在RRC重连接至第二目标小区的随机过程中，由于其他小区属于共享频谱网络，因此在RRC连接重建立的过程中，首先需要进行LBT，若LBT成功，则可进一步向第二目标小区发送RRC连接重建立请求，在所有BWP上连续LBT失败，则意味着无法发送RRC连接重建立请求。
若确定在所有带宽部分BWP上进行连续LBT失败，则在所述RLF报告中记录第三结果信息，所述第三结果信息为因在所有BWP上连续LBT失败导致未发送RRC连接重建立请求。第二目标小区为源小区、第一目标小区或除源小区和第一目标小区外的小区。
在本申请实施例中，通过在RLF报告中增加UE因在所有BWP上连续LBT失败导致没有机会发送RRC连接重建立请求的消息，能够避免基站在进行MRO统计时出现漏统计或者重复统计。
图8示例性地示出了本申请实施例的过早切换场景下的交互过程的示意图。如图8所示，该过程可以包括：
步骤S80：UE向源基站上报测量报告，源基站根据测量报告触发UE执行基站切换；
步骤S81：UE确定执行从源基站到共享频谱网络的目标基站的切换；
步骤S82：UE切换失败；
步骤S83：UE记录RLF报告；
步骤S84：UE尝试重建立到源基站，在RLF报告中记录表示因在所有BWP上连续LBT失败导致未发送RRC连接重建立请求的第三结果信息；
步骤S85：UE在其他基站重新接入网络，其他基站获取到UE记录的RLF报告；
步骤S86：其他基站将RLF报告发送给源基站进行切换失败分析；
步骤S87：源基站在进行MRO统计时不再漏统计或者重复统计。
在上述各实施例的基础上，作为一种可选实施例，用于表示因在所有BWP上连续LBT失败导致未发送RRC连接重建立请求的第三结果信息包括：(a)通过第二指定标识信息的方式记录在RLF报告中，且终端重建立小区标识信息在第二指定标识信息中被设置为空值；(b)终端重建立小区标识信息在第二指定标识信息中被设置为空值。
由于RLF报告中重建立小区标识位可选字段，在本申请实施例中，将该字段设置为空，当基站接收到RLF报告，根据该字段设置为空值，获知因所有BWP上连续 LBT失败导致UE未能发送RRC连接重建立请求。
在上述各实施例的基础上，本申请实施例还适用于多无线电双连接(Multi-Radio Dual Connectivity，MR-DC)场景下新增主辅小区或者主辅小区变换中发生LBT失败导致接入目标主辅小区失败的情况。
首先对MR-DC涉及的几个名称进行介绍和解释：
1)UE可能连接至一个主节点(Master Node，MN)，以及连接至一到多个辅节点(Secondary Node，SN)，并与这些网络节点进行信令和/或数据交互。MN与SN节点均可以为LTE/e-LTE/NR节点。当UE与有一个MN节点以及一个SN节点连接时，可称为双连接(Dual connection，DC)。
当UE处于连接态时，可以连接到一至多个网络侧节点，网络节点可以处于一个或者多个无线电接入技术(Radio Acess Technology，RAT)。例如，当MN为LTE节点而SN为NR节点时，为(NG)EN-DC双连接；当MN为NR节点而SN为LTE节点时，为NE-DC双连接；当MN与SN均为NR节点时，为NR-NR-DC。
2)SCG(Secondary Cell Group)是在MR-DC下，SN节点下的服务小区组，包括一个主辅小区(Primary Secondary cell，PSCell)和可能存在的一个或多个辅助小区(Secondary cell，Scells)。
RLF分为主小区组(Master Cell Group，MCG)和SCG两种，如果MCG发生了无线链路失败，UE触发RRC连接重建立过程，如果SCG发生了失败，UE向MN节点发送SCG失败消息(SCG failure information)。
SCG失败消息的作用为通知MN节点关于UE在SN节点发生的无线链路失败，同步重配置失败，无线信令承载(Signalling Radio Bearer，SRB)3上的SCG配置失败和SCG完整性校验失败信息。
SCG失败消息的消息内容主要包括发生失败的PSCell小区的ID，发生PSCell小区变换的源PSCell小区ID，从发生PSCell小区变换到SCG失败的时间长度，随机接入失败时记录随机接入相关信息，SCG失败类型，UE测量结果等。
3)主辅小区变换PSCell change和主辅小区新增PSCell新增流程
PSCell change(也称之为辅助节点变换Secondary Node Change)流程可以由MN或SN触发，以跨SN节点的主辅小区变换流程为例，从源SN(S-SN)到目标SN(T-SN)传递UE的上下文，同时在UE侧从源SN到目标SN改变SCG配置。在EN-DC场景下，由MN触发的主辅小区变换流程包括：
MN触发主辅小区变换流程，发送SgNB添加消息到目标SN请求分配资源；
MN触发SgNB删除消息到源SN，请求源SN停止继续向UE发送数据；
MN配置UE执行新的配置；
MN通知目标SN配置完成；
UE在目标主辅小区进行随机接入，如果目标主辅小区为共享网络小区，可能在随机 接入过程中可能发生LBT失败，导致接入目标主辅小区失败；
MN释放源SN配置；
主辅小区新增由MN触发，UE新增的目标主辅小区进行随机接入过程中可能发生LBT失败，导致随机接入失败。
当主辅小区变换或者新增主辅小区发生失败时，网络收到SCG失败消息后，将根据消息记录的内容优化网络参数配置，但是现有信息中没有LBT失败信息，将导致网络错误的优化网络参数配置。例如：当主辅小区接入失败时，传统上，网络将优化参数提升UE接入该主辅小区的门限，使UE在信号更好时再接入该主辅小区，但是实际上的随机接入失败不是信号质量差导致，而是共享网络被占用，和信号质量无关，不应该优化网络参数配置。
在上述各实施例的基础上，作为一种可选实施例，当目标指令用于指示UE进行主辅小区变换，所述方法还包括：若在随机接入目标主辅小区过程中发生LBT失败，则根据主辅小区变换结果，在SCG失败消息中的至少一种报告中记录LBT失败信息。
为了使网络知道随机接入失败是由于LBT失败导致，需要在SCG失败消息中增加LBT失败信息，具体为下列至少一项：
1.增加LBT失败指示信息，标识主辅小区变换失败或者主辅小区新增失败是由于LBT导致；
2.在SCG失败消息的随机接入信息中增加记录如下至少一项：
1)用于表示每次随机接入尝试前进行LBT的过程中，是否发生了连续LBT失败的标识信息。
2)在接入目标小区过程中，多次随机接入尝试中发生了LBT失败的次数。在一些实施例中，该次数可以为每个波束下发生的LBT失败的次数，也可以为全部波束下发生的LBT失败的总次数。
在上述各实施例的基础上，MR-DC场景下还可能出现主辅小区新增或者主辅小区变换过程成功但是生成了成功的主辅小区变换报告的情况：在主辅小区新增或者主辅小区变换过程中，如果UE在目标主辅小区接入成功，但是接入过程中随机接入目标主辅小区时间太长，将触发UE生成成功的主辅小区变换报告。
网络使用成功的主辅小区变换报告进行参数优化，减少随机接入目标主辅小区的时间，因为接入时间太长，虽然没有接入失败，但是临界失败了，网络还是需要参数优化调整。
例如，调整主辅小区新增或者主辅小区变换的触发门限，使下次接入目标主辅小区时可以信号更高，质量更好。但是如果是在接入目标主辅小区过程中发送了LBT失败，也将导致随机接入目标主辅小区时间长，但是原因为主辅小区共享小区被其他网络占用，导致本次随机接入尝试失败，不是信号质量问题。
为了避免网络错误优化网络参数，需要在成功的PSCell变换报告中增加LBT失败信 息，具体为在成功的主辅小区变换报告中的随机接入信息中增加记录如下至少一项：
1)每次随机接入尝试前进行LBT过程，是否发生了连续LBT失败的标识信息。
2)在接入目标小区过程中，多次随机接入尝试中发生了LBT失败的次数，可以为以下至少一种：
每个波束下发生的LBT失败的次数；
全部波束下发生的LBT失败的总次数。
当记录每个波束下发生的LBT失败的次数时，可以以序列的方式进行记录，即，序列中的每个元素用于表征相应波束下发生的LBT失败的次数。当记录全部波束下发送的LBT失败的总次数时，该总次数是对所有波束下发生的LBT失败的次数的汇总后的结果。
