在本说明书中，下述用于描述本公开原理的各种实施例只是说明，不应该以任何方式解释为限制公开的范围。参照附图的下述描述用于帮助全面理解由权利要求及其等同物限定的本公开的示例性实施例。下述描述包括多种具体细节来帮助理解，但这些细节应认为仅仅是示例性的。因此，本领域普通技术人员应认识到，在不背离本公开的范围和精神的情况下，可以对本文中描述的实施例进行多种改变和修改。此外，为了清楚和简洁起见，省略了公知功能和结构的描述。此外，贯穿附图，相同参考数字用于相似功能和操作。
下文以长期演进系统(Long Term Evolution，LTE)/NR移动通信系统及其后续的演进版本作为示例应用环境，具体描述了根据本公开的多个实施方式。然而，需要指出的是，本公开不限于以下实施方式，而是可适用于更多其它的无线通信系统。若无特殊说明，在本公开中， 小区和基站的概念可以互相替换；LTE系统也用于指代5G及其之后的LTE系统(如称为eLTE系统，或者可以连接到5G核心网的LTE系统)，同时LTE可以用演进的通用陆地无线接入(Evolved Universal Terrestrial Radio Access，E-UTRA)或演进的通用陆地无线接入网E-UTRAN来替换。在本公开中，PSCell变更指的是网络侧发起的主辅小区的变更，包含小区间的主辅小区变更也包含小区内的主辅小区变更，即UE的PSCell从源PSCell变更为目标PSCell，其中源PSCell和目标PSCell可以是同一个小区也可以是不同的小区。在此过程中，用于接入层安全的秘钥或安全算法也可随之更新或不更新。所述安全包括加密解密和完整性保护。源PSCell也可称为源辅基站、源辅小区组(Secondary Cell Group，SCG)、称源光束(beam)、源传输点(Transmission point，TRP)或源小区；目标PSCell也可称为目标辅基站、目标光束、目标传输点、目标辅小区组SCG或目标小区。本公开所述PSCell变更命令用于触发UE执行PSCell变更，在NR系统中是包含同步重配置(Reconfigurationwithsync)信息元素的RRC重配置消息，更进一步地，是包含用于SCG的同步重配置(Reconfigurationwithsync)信息元素的RRC重配置消息。此时，PSCell变更也可称为SCG的同步重配置或PSCell的同步重配置。其中，所述同步重配置信息元素可以包含目标小区的配置信息，例如目标小区标识、目标小区频率、目标小区的公共配置如系统信息、UE接入到目标小区所使用的随机接入配置、UE在目标小区的安全参数配置、UE在目标小区的无线承载配置等。为便于描述，本公开中小区变更命令和包含小区变更命令的RRC消息等同，指触发UE执行小区变更的RRC消息或RRC消息中的配置。小区变更配置指小区变更命令中的全部或部分配置。取消、释放、删除、清空和清除等可以替换。执行、使用和应用可替换。配置和重配置可以替换。监测(monitor)和检测(detect)可替换，如无特殊说明，小区变更指的是PSCell变更。
下列描述了本公开涉及的现有技术中的过程或概念。
NR系统中的小区变更配置：
在NR系统中，用于小区变更命令的RRC重配置消息承载着来自目标基站的RRC配置，包含但不限于下述RRC配置(具体请参见3GPP技术标准协议38.331中的6.2.2章节)：
-测量配置：用于配置UE所执行的频率内、频率间和无线接入技术间的测量。如测量对象配置、测量上报配置、测量空隙(gap)配置等。
-小区组配置(cellGroupConfig信息元素)，用于配置辅小区组。包括数据无线承载/信令无线承载对应的无线链路控制(Radio Link Control，RLC)承载配置(rlc-bearerToAddModList信息元素和rlc-bearerToreleaselist信息元素)、媒介接入控制(Medium Access Control，MAC)配置(MAC-cellgroupconfig信息元素)、物理层配置、辅小区添加/修改/释放配置、特殊小区(Special cell，SpCell)配置等。其中，SpCell配置中包含小区索引号、小区变更信息(reconfigurationWithSync信息元素)、无线链路失败相关定时器及常数配置、无线链路检测(Radio Link Monitoring，RLM)配置、特殊小区专用配置等。其中reconfigurationwithsync信息元素包含小区变更相关信息如服务小区配置公共信息、UE在目标小区的小区无线网络临时标识C-RNTI、小区变更过程监控定时器T304配置、用于向目标小区随机接入过程的随机接入专用配置等。
-无线承载配置(radiobearerConfig信息元素)，用于配置数据无线承载(Data Radio Bearer，DRB)和/或信令无线承载(Signaling Radio Bearer，SRB)的服务数据应用协议层(Service Data Application Protocol，SDAP)和包数据汇聚协议层(Packet Data Convergence Protocol，PDCP)。
-密钥更新配置。
双连接(Dual Connectivity)：
为了提高UE的数据传输效率，UE同时与两个基站建立链路，也就是UE所使用的无线资源由位于两个基站的不同调度器提供。这两个基站与UE之间的无线接入可以是相同或不同的制式(Radio Access  Technology，RAT)，如都是NR，或一个是NR，一个是LTE也称演进的通用陆地无线接入(Evolved Universal Terrestrial Radio Access，E-UTRA)。在这两个基站中，一个称为主基站(Master Node，MN)或MgNB、MeNB，主基站下的服务小区组称为主小区组(Master Cell Group，MCG)；另一个称为辅基站(Secondary Node，SN)或SgNB、SeNB，辅基站下的服务小区组称为辅小区组(Secondary Cell Group，SCG)。当主基站是LTE，辅基站是NR时的DC称为EN-DC(使用4G核心网)或NGEN-DC(使用5G核心网)；当主基站和辅基站都是NR时的DC称为NR-DC。MCG包含一个主小区(Primary Cell，PCell)和可选的一个或多个辅小区(Secondary Cell，SCell)。PCell工作在主频率上，UE通过主频率执行初始连接建立过程或连接重建立过程。SCG包含一个主SCG小区(Primary SCG Cell，PSCell)和可选的一个或多个SCell。PSCell是指UE在执行SCG的同步重配置过程时执行随机接入的SCG小区。PCell和PSCell也统称为特殊小区SpCell。在配置了DC时，支持对UE的DRB和SRB配置为分裂承载(split bearer)。在未配置为split SRB时，SRB1和SRB2是通过MCG路径传输的。此外，在配置了DC时，也可以为SN建立SRB3，用于传输SN和UE之间与SCG关联的配置等。SRB3的建立和释放都是由SN来决定的。
NR系统中的PSCell变更过程：
PSCell的变更可以由MN发起，也可以由SN发起。MN或SN可以基于UE上报的对源PSCell或邻小区的测量结果或邻小区的负载等因素，来发起PSCell的变更。在有MN参与的PSCell变更过程中(无论是MN发起还是SN发起的)，用于PSCell的小区变更命令包含在SRB1的RRC重配置消息中发给UE。PSCell变更命令是对于SCG的RRC重配置消息。当通过MCG链路发送给UE时，一般包含在mrdc-SecondaryCellGroupConfig信息元素或nr-SecondaryCellGroupConfig信息元素中并嵌套在SRB1的RRC重配置消息中。若PSCell的变更无需MN参与，如intra-SN的PSCell变 更场景，此时SN可以自主生成PSCell变更命令的RRC重配置消息并通过SCG链路的SRB3发送给UE。
收到PSCell变更命令的UE立即应用该小区变更命令的配置执行PSCell变更，包含到PSCell的随机接入过程。UE通过一个定时器T304来检测小区变更过程，当小区变更过程发起时，UE开启T304定时器；当小区变更过程完成(随机接入过程成功完成)时，UE停止定时器T304；当T304超时，UE认为PSCell变更失败或同步重配置失败。
成功切换报告：
版本17的NR系统中引入成功切换时的切换信息报告。此处切换指的是PCell变更或PCell的同步重配置。切换命令指的是包含用于MCG的同步重配置信息元素的RRC重配置消息。成功切换时的切换信息报告也简称成功切换报告(Successful Handover Report，SHR)。这是因为，在NR系统中单靠已有机制中的无线链路失败RLF报告来执行网络优化可能会使得数据收集过程变得漫长，而在切换成功时切换信息报告使得网络侧能更快获得移动性过程中的足够样本数。其次，即使是对于成功的切换场景，其移动性参数还是有进一步优化的空间的。对于SHR的内容，可以包含下述一种或多种：切换的源小区标识；切换的目标小区标识；切换的源小区或目标小区的测量结果；邻居小区测量结果；指示SHR被触发的原因(即哪一个触发条件被满足)等。所述切换成功包括用于向目标基站响应切换命令RRC重配置消息的RRC重配置完成消息成功发送或者MAC层成功完成到目标基站的随机接入过程。网络侧需要向UE配置成功切换报告的触发条件(如T310、T312、T304对应的门限值)，只有当配置的一个或多个触发条件满足(如收到切换命令时源小区的T310或T312的运行值超过所配置的对应的门限值，切换成功完成时的T304的运行值超过了所配置的对应的门限值)时，UE才会记录所述成功切换的切换信息。其中，与源小区相关的触发条件如T310门限值或T312门限值由源小区配置给UE，与目标小区相关的触发条件如T304门限值由目标小区配置给UE。UE可以通过RRC消息告知网络侧其上有可用的成功切换报告(如 successHO-InfoAvailable信息元素来指示)。网络侧在收到所述指示后，可以通过RRC消息(如UEInformationRequest消息中的successHO-ReportReq指示)来请求UE上报其保存的成功切换信息报告。UE会在响应RRC消息中将所保存的无线链路失败报告(UEInformationResponse消息中的successHO-Report)上报给网络侧。UE上保存的成功切换报告最多可以保存48小时。
如上所述，版本17的NR系统中标准化了对PCell切换时SHR机制以进一步对切换场景下的移动鲁棒性进行优化。而版本18中一个研究目标是引入对PSCell变更场景下的PSCell变更报告(Successful PSCell Change Report，SPCR)，通过向网络侧上报成功的PSCell变更过程的信息，使得网络侧能对PSCell变更的参数进行优化和调整，以提高PSCell的移动鲁棒性。在本公开中，假定SPCR的上报过程与SHR类似，即在成功执行了PSCell变更过程的UE若确定要生成一个SPCR，则UE在对应的UE变量中保存所生成的SPCR的内容，并通过RRC消息向网络侧指示其上有保存的SPCR；在收到网络侧的指示其上报SPCR的请求后，UE将所保存的SPCR包含在RRC消息中上报给网络侧。与切换场景不同的是，在PSCell变更场景下，除了源PSCell和目标PSCell的参与，在MN触发的SN修改过程或MN触发的SN变更过程中，除了源PSCell和目标PSCell的参与，MN也参与到了该过程中。那么在成功PSCell变更报告对应的网络优化过程中，是否要考虑将SPCR递送给MN以使得MN参与到PSCell的移动鲁棒性优化过程中成为本公开所关注的问题。更进一步地，在考虑MN参与PSCell的移动鲁棒性优化问题时，如何实现所述SPCR可以递送给MN，以及UE如何确定SPCR是否需要递送给MN是本公开中所关注的问题。这是因为，生成SPCR的UE在执行PSCell变更时，若PSCell变更命令是通过SRB1上接收到的，那么UE是无法知道该PSCell变更过程是MN发起的还是SN发起的。
下述各实施例基于上述问题给出解决方法，如无特殊说明，实施 例之间并不是互斥的，实施例之间可以结合，或者一些概念或定义在各实施例之间是可以通用的。
实施例1
该实施例给出了一种在UE上执行的信息报告方法。通过该实施例所述方法，UE可以基于从网络侧收到的指示信息或SPCR配置来确定是否在成功PSCell变更报告SPCR中携带PCell信息上报给网络侧。UE在SPCR中包含的PCell信息，使得从UE上取回SPCR的基站可以根据SPCR中携带的PCell信息，将该SPCR递送给相对应的PCell基站(即前述MN)。所述MN可以基于所收到的SPCR中的信息来进行PSCell变更参数的调整和优化。此外，UE基于从网络侧收到的指示信息或SPCR配置来确定是否在成功PSCell变更报告SPCR中携带PCell信息上报给网络侧，也可以避免UE总是在SPCR中携带PCell信息而带来的不必要的信令开销。
以下，对本公开的实施例1进行详细说明，图1是表示本公开的实施例1中的信息报告方法的示意流程图。如图1所示，本公开的实施例1中的信息报告方法可以包含如下步骤。
步骤101：在成功完成一个PSCell变更过程后，UE触发了SPCR的记录，即UE确定在对应的UE变量中保存该PSCell变更过程对应的SPCR信息。
所述成功完成一个PSCell变更过程，通常指的是用于PSCell/SCG的同步重配置过程中所触发随机接入过程成功完成，或者用于响应PSCell变更命令即包含SCG的同步重配置的RRC重配置消息的响应消息即RRC重配置完成消息已发送。
可选地，UE触发了SPCR的记录，类似于版本17中的SHR机制，UE在所配置的SPCR触发条件满足时触发SPCR的记录。即UE根据SPCR配置中的触发条件是否满足来确定是否保存该过程对应的SPCR信息。所述触发条件可以是用于PSCell的T310门限值、用于PSCell的T312门限值，或者用于SCG的T304门限值。在一种方式 中，所述门限值是一个百分比例门限值。例如，当UE收到PSCell变更命令时执行PSCell的同步重配置前的源PSCell的T310的运行值与T310的配置值的比率超过了所配置的门限值时，UE确定保存该过程对应的SPCR信息。
步骤102：UE在所保存的SPCR信息中，包含其PCell信息。
所述PCell指的是UE在收到PSCell变更命令时执行PSCell的同步重配置前所关联的主小区。优选地，所述PCell信息，是所述PCell对应的小区标识，如物理小区标识(Physical Cell Identity，PCI)、小区载波频率(Absolute Radio Frequency Channel Number，ARFCN)、全局小区标识(Global Cell Identity，GCI)、跟踪区域码(Tracking Area Code，TAC)的一种或多种。备选地，所述PCell信息还包括PCell的测量结果，即用于表征PCell下行链路信号质量的信息。可选地，所述测量结果是UE在收到PSCell变更命令时执行PSCell的同步重配置前所获得的最新的测量结果。
可选地，在一种实现方式1中，当所述PSCell变更命令是通过SRB1接收时，UE在所保存的SPCR信息中包含其PCell信息。可选地，所述PSCell变更命令是通过SRB1接收，指的是所述用于PSCell的同步重配置的RRC重配置消息是包含在mrdc-SecondaryCellGroup中通过SRB1接收的。在该实现方式中，当所述PSCell变更命令是通过SRB3接收时，UE不在所保存的SPCR信息中包含其PCell信息。
可选地，在一种实现方式2中，当UE判断所述PSCell变更过程是由MN发起时，UE在所保存的SPCR信息中包含对应的PCell信息。UE基于从网络侧接收到的第一信息来确定所述PSCell变更过程是否由MN发起。所述第一信息指示了该PSCell变更过程是否是由MN发起的。例如，若所述第一信息设置为MN，则UE认为所述PSCell变更过程是由MN发起的。所述第一信息可以包含在对应的PSCell变更命令中，也可以包含在PSCell变更命令的外层RRC重配置消息中，即由MN设置该第一信息并包含在RRC重配置消息中。
可选地，在一种实现方式3中，UE基于网络侧的第二信息来确 定是否在所保存的SPCR信息中包含对应的PCell信息。也就是说，UE从网络侧接收第二信息，所述第二信息显式地使能/指示了UE将PCell信息包含在对应的SPCR信息中。所述第二信息可以包含在对应的PSCell变更命令中配置给UE，也可以包含在PSCell变更命令的外层RRC重配置消息中，即由MN设置该第一信息并包含在RRC重配置消息中。
可选地，在一种实现方式4中，UE基于对应的SPCR配置来确定是否在所保存的SPCR信息中包含对应的PCell信息。在该实现方式中，MN和SN都可以配置UE的SPCR配置。可选地，若只有MN或SN其中的一方对UE配置了SPCR配置，那么UE在生成SPCR时，判断若所对应的SPCR配置是由MN配置的，则UE在SPCR中包含对应的PCell信息；否则若所对应的SPCR配置是由SN配置的，则UE在SPCR中不包含对应的PCell信息。可选地，UE在生成SPCR时，判断若触发SPCR的触发原因对应的SPCR配置是由MN配置的，则UE在SPCR中包含对应的PCell信息。这主要是考虑到MN和SN都同时对UE配置了SPCR配置的情况。例如配置了不同的T310门限值(由MN配置的TH1和和由SN配置的TH2)，那么若UE确定记录SPCR的触发是由于T310的运行值和其配置值的比率超过了门限值TH1，因为TH1是由MN配置的，则UE在SPCR中包含对应的PCell信息。可选地，UE在SPCR消息中还包括了用于指示所述SPCR的触发原因及所述触发原因对应的触发条件/SPCR配置是由MN配置的还是由SN配置的信息。
可选地，上述外层RRC消息也可以是RRC恢复消息。
可选地，上述第一信息和第二信息也可以不和PSCell变更命令一起发送给UE，即可以在PSCell变更命令之前的其他RRC消息中发送给UE。
显然地，在步骤101之前还包括UE从网络侧接收PSCell变更命令，并应用该命令执行到PSCell的同步重配置。
可选地，该实施例也可适用于PSCell添加的情况，也就是说所述 PSCell变更也可以是PSCell添加。
可选地，该实施例也可适用于条件PSCell变更(Conditional PSCell Change，CPC)的情况，也称用于SCG的条件重配置。
实施例2
该实施例给出了一种在UE上执行的PSCell变更信息报告方法。通过该实施例所述方法，则UE可以在SPCR中将相关信息上报给基站，以向网络侧提供更精确的PSCell变更信息。该实施例给出了UE通过RRC过程上报实施例1中所述信息报告时的信令流程的方法。
以下，对本公开的实施例2进行详细说明，图2是表示本公开的实施例2中的信息报告方法的示意流程图。如图2所示，本公开的实施例2中的信息报告方法可以包含如下步骤。
步骤201：UE收到来自网络侧的UEInformationRequest消息，其中携带了用于请求UE上报所保存的SPCR的指示/请求。
步骤202：UE将所保存的SPCR中的内容包含在UEInformationResponse消息中，向网络侧发送UEInformationResponse消息。所述UEInformationResponse消息中包含的SPCR报告中包含前述实施例1中的PCell相关信息。
