具体实施方式
根据结合附图对本公开示例性实施例的以下详细描述，本公开的其它方面、优势和突出特征对于本领域技术人员将变得显而易见。
在本公开中，术语“包括”和“含有”及其派生词意为包括而非限制；术语“或”是包含性的，意为和/或。
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***(Long Term Evolution，LTE)/NR移动通信***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***。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***也用于指代5G及其之后的LTE***(如称为eLTE***，或者可以连接到5G核心网的LTE***)，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。本公开中，RRC inactive状态也可对应于LTE***中的RRC连接被挂起的RRC空闲状态。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。链路和连接可以替换。监测(monitor)和检测(detect)可替换。
下述先简要描述本公开实施例所涉及到的在先技术。
DC下的辅小区组SCG和PSCell
DC场景下，UE可以同时通过两个基站获取无线资源。其中一个是主基站(Master Node，MN)，是UE维持RRC连接的基站，通过初始接入过程或切换过程而接入的基站；另外一个称为辅基站(Secondary Node，SN)，可以为UE提供额外的无线资源。对于一个UE，MN可以包含一个或多个服务小区，称为主小区组(Master Cell Group，MCG)，其中包含一个主小区(PCell)；SN也可包含一个或 多个服务小区，称为辅小区组(Secondary Cell Group，SCG)，其中包含一个主辅小区组小区/或主辅小区PSCell。PCell和PSCell又可统称为特殊小区spCell。本公开中，SN和SCG可以替换，MN和MCG可以替换。SN添加/变更/释放、SCG添加/变更/释放、MR-DC添加/变更/释放、PSCell添加/变更/释放在一定程度上可以替换。
RRC恢复过程中的SCG配置处理
在当前的NR/LTE***中，UE在进入RRC inactive状态时，若其被配置了SCG，则在UE的非激活态接入层上下文中保存所述SCG配置(如mrdc-SecondaryCellGroup配置)。在后续的用于恢复RRC连接的RRC连接恢复过程中，UE向网络侧发送RRCResumerequest消息请求恢复RRC连接，在收到的响应消息RRCResume消息中，若没有包含用于指示恢复所保存的SCG配置的restoreSCG指示信息，则UE从所保存的UE非激活态接入层上下文中释放对应的多无线双连接(Multi-Radio Dual Connectivity，MR-DC)相关的配置即SCG配置；否则，UE会从UE非激活态接入层上下文中恢复所保存的SCG配置。同时在该RRCresume消息中还可包含一个mrdc-SecondaryCellGroup配置，该SCG配置中可以执行PSCell的变更，即包含一个reconfigurationWithSync信息元素，且其中的小区标识不同于当前的PSCell的小区标识。当然所述SCG配置也可以是对当前的PSCell的重配置，即不包含PSCell的变更。
也就是说，在RRC恢复过程中，根据网络侧的配置，UE所保存的PSCell可以发生三种情况：1：释放整个SCG配置包含PSCell的配置；2：重配置SCG且PSCell变更；3：重配置SCG且PSCell不变更。
现有机制中的移动信息报告机制：
当前的LTE***和版本16的NR***中，UE会记录移动历史信息(Mobility History Information，MHI)，在本公开中，也简称作移动信息。所述MHI记录了UE所经历的服务小区/主小区(Primary Cell，PCell))的变更信息。在RRC空闲态和RRC连接态下的UE当发生 服务小区/主小区变更时，在UE变量VarMobilityHistoryReport中增加一个条目(entry)，在visitedCellId信息元素中记录之前的服务小区/PCell的小区标识(全局小区标识global cell identity或物理小区标识physical cell identity和小区的载波频率)，还包括在该小区所停留的时间(以timeSpent信息元素标识)。在LTE***中，当UE进入E-UTRA时若之前处于out of service状态或者使用的是其他接入技术(Radio Access Technology，RAT)，UE也会在变量VarMobilityHistoryReport中增加一个条目，在其中的timeSpent信息元素中记录UE处于E-UTRA之外的之间。这里的E-UTRA之外即包括out of service状态或使用其他RAT。在NR***中，当UE进入正常驻留状态(camped normally state)或E-UTRA时，若之前处于LTE或NR的“any cell selection”或“camped on any cell”状态，则UE在变量VarMobilityHistoryReport中增加一个条目，并设置其他中timeSpent元素为处于LTE或NR的“any cell selection”或“camped on any cell”状态所经历的时间。3GPP协议中定义了UE所保存的MHI的条目的最大数，比如16，当UE在执行上述增加一个新条目的操作时，若所保存的条目数量已达到最大值，则UE在增加新条目之前，删除所保存的MHI条目中最旧的条目。
当UE通过RRC连接建立或RRC连接恢复过程进入RRC连接状态时，若UE支持保存MHI且VarMobilityHistoryReport变量中有可用的MHI，则UE在RRC连接建立完成消息或RRC连接恢复完成消息中包含一个用于告知基站其有保存的MHI的指示(mobilityHistoryAvail信息元素)，设置该信息元素的值为TRUE。UE在随后的UE information过程中将所保存的MHI上报给基站。具体地，基站通过在UEInformationRequest消息中携带置为TRUE的mobilityHistoryReportReq信息元素来请求UE上报所保存的MHI，UE则在响应的UEInformationResponse消息中将所保存的MHI的条目包含在mobilityHistoryReport信息元素中上报给基站。此外，UE还会在mobilityHistoryReport信息元素中包含一个条目用来记录当前的小区 信息，即设置该条目的visitedCellId信息元素为当前小区的全局小区标识和设置timeSpent信息元素为在当前小区所经历的时间。
上述机制中，网络侧通过获取UE的MHI，可以获知UE的移动轨迹并在一定程度上确定UE的移动速度。网络侧在决定该UE的移动性操作如切换参数的配置、切换目标小区的选择时可以结合所获取的信息进行更优化的配置，从而确保UE的移动性能。
现有机制中所述小区信息是对于空闲态或RRC inactive非活动态的服务小区或RRC连接态的PCell而言的。在LTE/NR***中的DC场景下，除了PCell的移动性，UE同时执行PSCell的移动性。对于PSCell的变更，辅基站(Secondary Node，SN)可以自行发起PSCell的变更，而无需主基站(Master Node，MN)参与。首先，现有MHI机制中，SN无法获取PCell/服务小区的MHI；其次，考虑到MN和SN的网络部署情况的不同(比如在EN-DC的场景下，MN和SN为不同的RAT)，即使SN可以从MN获取PCell/服务小区的MHI，因为SN缺乏对相关PCell/服务小区的网络部署信息，如小区范围大小等，SN可能无法从MHI中获取有帮助的信息。考虑到上述原因，一种可行的方法是，对MHI进行增强，所述增强包括UE记录对于SCG PSCell的MHI，该MHI可以上报给SN，也可以上报给MN，以用于MN触发的PSCell添加/变更时以及SN触发的PSCell变更时的参数优化。为了便于描述，本公开中，将现有机制中的MHI称为M-MHI，而将基于PSCell变更而记录的MHI称为S-MHI。
本公开就如何在UE侧实现S-MHI的记录问题提出了解决方法。
与PCell不同的是，UE的PSCell是可选的，不是必须存在的。在一些情况下，比如处于RRC连接态的UE的业务量较小时，网络侧可以选择释放UE的SCG或者不配置SCG，使得UE处于单连接状态，此时UE没有配置的PSCell。此外，如前所述，当UE进入RRC inactive状态时，UE会将其SCG配置保存在UE非激活态接入层上下文中。但处于RRC inactive态的UE并不执行PSCell的移动性，而在RRC连接恢复时，网络侧可以决定是否保留或变更该PSCell。上述两种情 况导致UE在PSCell的经历是断断续续的。在这些情况下的S-MHI的记录无法直接采用现有的MHI机制。
下述是本公开中基于上述问题在UE上执行的若干实施例。
实施例1
该实施例提出了一种UE进入RRC inactive状态的S-MHI记录方法。
图1是表示本发明的实施例1中的移动信息报告方法的流程图。在实施例1中，如图1所示，在步骤S101中，UE执行从RRC连接态进入RRC非激活态的操作。
在UE执行从RRC连接态进入RRC非激活态的操作的情况下，在步骤S102中，UE对S-MHI进行记录、保存，以使得S-MHI可以包含当前的PSCell的小区标识以及在该PSCell中所经历的时间。
作为一例，例如，当UE执行进入RRC inactive状态的操作时，若UE支持保存S-MHI且UE被配置了SCG，则UE在用于保存S-MHI的UE变量中增加一个条目，所述条目用于记录UE当前的PSCell移动信息。所述条目中包括当前的PSCell的小区标识以及在该PSCell中所经历的时间。可选地，所述条目中还可以包括UE在被配置了该PSCell时所对应的PCell的小区标识。考虑到PCell切换时UE的PSCell可以不变更的场景，所述PSCell所对应的PCell可以是多于一个的。所述小区标识可以是全局小区标识或物理小区标识。
所述UE执行进入RRC inactive状态的操作时，可以发生在UE执行RRC释放时，如当UE收到用于挂起RRC连接的RRC释放消息时而执行的RRC释放操作。优选地，所述UE被配置了SCG指的是UE有配置的secondaryCellGroup配置或mrdc-secondarycellGroupConfig配置。
实施例2
该实施例提出了一种UE从RRC inactive通过RRC连接恢复过程 进入RRC连接态的S-MHI记录方法。值得指出的是，该方法也适用于UE从RRC空闲态通过RRC连接建立过程进入RRC连接态的S-MHI记录方法。通过该实施例，UE将在RRC inactive状态或RRC空闲态所经历的时间也记录在S-MHI中，从而向基站提供更多的用于移动性评估的信息。
图2是表示本发明的实施例2中的移动信息报告方法的流程图。在实施例2中，如图2所示，在步骤S201中，UE从RRC非激活态通过RRC连接恢复过程进入RRC连接态、或者从RRC空闲态通过RRC连接建立过程进入RRC连接态。
此外，在步骤202中，UE保存S-MHI(即，基于主辅小区PSCell的移动历史信息)，S-MHI可以包含UE在进入RRC连接态之前在RRC非激活态或者RRC空闲态所经历的时间。
作为一例，例如，当UE进入RRC连接态时，若UE支持保存S-MHI，则UE在用于保存S-MHI的UE变量中增加一个条目，所述条目用于记录UE在进入RRC连接态之前在RRC inactive状态所经历的时间(即未使用SCG的时间)。所述条目中包括UE在从上一次RRC连接被释放到此次进入RRC连接态之间处于RRC inactive状态所经历的时间。可选地所述条目中还可以包括UE在这期间所对应的一个或多个PCell的小区标识。所述小区标识可以是全局小区标识或物理小区标识。因为上述RRC inactive状态的时间内，UE并未使用SCG，所以即使UE此时有保存的SCG/PSCell配置，所述条目中并不包含任何PSCell标识。
可选地，对于RRC inactive的UE，上述操作仅在当UE在进入RRC连接态之前被配置了SCG时或有保存的SCG配置时执行。
所述UE进入RRC连接态，可以指的是UE在RRC恢复过程中接收到了RRC恢复消息。可选地，指的是成功接收并应用了所接收到的RRC恢复消息，也可指UE将RRC恢复完成消息递送给下层发送。
当上述方法适用于RRC空闲态时，上述RRC inactive状态可替换为RRC空闲态。所述UE进入RRC连接态，可以指的是UE在RRC 建立过程中接收到了RRC建立消息。可选地，指的是成功接收并应用了所接收到的RRC建立消息，也可指UE将RRC建立完成消息递送给下层发送。
实施例3
该实施例提出了一种UE从RRC inactive通过RRC连接恢复过程进入RRC连接态的S-MHI记录方法。
该实施例适可以用于当UE在RRC恢复过程中接收到了包含restoreSCG信息元素的RRC恢复消息，且RRC恢复消息中指示了一个PSCell变更的情况。
作为一例，例如，当发生PSCell成功变更时，若UE支持保存S-MHI，则UE在用于保存S-MHI的UE变量中增加一个条目，所述条目用于记录UE前一个PSCell(即PSCell变更时的源PSCell)的移动信息。UE执行上述操作时，排除所述PSCell的变更发生在RRC恢复过程中的情况，即PSCell的变更命令是包含在RRC恢复消息中的情况。所述条目中包括前一个PSCell的小区标识以及在该PSCell中所经历的时间。可选地，所述条目中还可以包括UE在被配置了该PSCell时所对应的PCell的小区标识。考虑到PCell切换时UE的PSCell可以不变更的场景，所述PSCell所对应的PCell可以是多于一个的。所述小区标识可以是全局小区标识或物理小区标识。
所述PSCell变更指的是执行了用于SCG的同步重配置(reconfigurationWithSync)，优选地，还包括PSCell不是同一个(同步重配置中的PSCell标识不同于之前的PSCell标识)。所述PSCell变更命令指的是包含了用于SCG的同步重配置的RRC消息。所述PSCell成功变更指的是当用于SCG的同步重配置信息元素包含在所述RRC消息中且MAC层成功完成了由此触发的随机接入过程。
实施例4
该实施例提出了一种UE从RRC inactive通过RRC连接恢复过程 进入RRC连接态的S-MHI记录方法。
该实施例可以适用于当UE在RRC恢复过程中接收到了不包含restoreSCG信息元素的RRC恢复消息的情况。
作为一例，例如，当UE接收到RRC恢复消息时，若该消息中不包含restoreSCG信息元素，UE执行MR-DC相关配置的释放，释放MR-DC或SCG，在释放MR-DC或SCG时UE并不执行S-MHI的更新。
换句话说，当执行MR-DC或SCG的释放时若UE支持保存S-MHI，则UE在用于保存S-MHI的UE变量中增加一个条目，所述条目用于记录UE前一个PSCell的移动信息。UE执行上述操作时，排除所述MR-DC或SCG的释放是发生在RRC恢复过程中的情况，即restoreSCG信息元素不包含在RRC恢复消息中的情况。
所述条目中包括前一个PSCell的小区标识以及在该PSCell中所经历的时间。可选地，所述条目中还可以包括UE在被配置了该PSCell时所对应的PCell的小区标识。考虑到PCell切换时UE的PSCell可以不变更的场景，所述PSCell所对应的PCell可以是多于一个的。所述小区标识可以是全局小区标识或物理小区标识。
实施例5
该实施例提出了一种UE从RRC inactive进入RRC连接态后发生的第一个PSCell变更时的S-MHI记录方法。
该实施例可以适用于UE在RRC恢复过程中执行了MR-DC/SCG的恢复但并没有变更PSCell，在后续接收到了包含在RRC重配置消息中的PSCell变更命令的情况。即当UE在RRC恢复过程中接收到了包含restoreSCG信息元素的RRC恢复消息，但RRC恢复消息中并不包含用于SCG的同步重配置，而是在后续接收到了RRC重配置消息中包含了用于SCG的同步重配置。
作为一例，例如，当发生PSCell成功变更时，若UE支持保存S-MHI，则UE在用于保存S-MHI的UE变量中增加一个条目，所述 条目用于记录UE前一个PSCell(即PSCell变更时的源PSCell)的移动信息。所述条目中包括前一个PSCell的小区标识和在该PSCell中所经历的时间。当所述PSCell的变更是UE通过RRC恢复过程进入RRC连接状态以来的第一次PSCell变更，则所述时间是从UE的RRC连接被恢复以来在前一个PSCell所经历的时间。所述RRC连接被恢复以来也可表述为所述UE进入到RRC连接态以来。所述UE进入RRC连接状态以来的第一次PSCell变更也可表述为从UE接收到RRC恢复消息之后所接收到的第一个用于SCG的同步重配置，优选地，所述同步重配置中包含了新的PSCell标识(指示了PSCell的变更)。
可选地，所述条目中还可以包括UE在被配置了该PSCell时所对应的PCell的小区标识。考虑到PCell切换时UE的PSCell可以不变更的场景，所述PSCell所对应的PCell可以是多于一个的。所述小区标识可以是全局小区标识或物理小区标识。
所述PSCell变更指的是执行了用于SCG的同步重配置(reconfigurationWithSync)，优选地，还包括PSCell不是同一个(同步重配置中的PSCell标识不同于之前的PSCell)。所述PSCell变更命令指的是包含了用于SCG的同步重配置的RRC消息。所述PSCell成功变更指的是当用于SCG的同步重配置信息元素包含在所述RRC消息中且MAC层成功完成了由此触发的随机接入过程。
实施例6
该实施例给出了一种PSCell添加时的S-MHI记录方法。
作为一例，例如，当UE执行PSCell的添加成功时，若UE支持保存S-MHI，则UE在用于保存S-MHI的UE变量中增加一个条目，所述条目用于记录UE在PSCell添加前处于无SCG/PSCell配置状态所经历的时间。
优选地，当所述PSCell的添加是UE通过RRC恢复/建立过程进入RRC连接状态以来的第一次PSCell添加，则所述时间是从UE的RRC连接被恢复/建立以来到所述第一次PSCell的添加所经历的时间。 所述RRC连接被恢复/建立以来也可表述为所述UE进入到RRC连接态以来。所述UE进入RRC连接状态以来的第一次PSCell添加也可表述为从UE接收到RRC恢复/建立消息之后所接收到的第一个用于SCG的同步重配置。当所述PSCell的添加不是UE进入连接态以来第一次PSCell添加，也就是说UE在此次RRC连接过程中此次PSCell添加之前执行过MR-DC/SCG/PSCell释放或被配置过SCG/PSCell，则所述时间是从前一次MR-DC/SCG/PSCell释放以来到所述此次PSCell添加所经历的时间。可选地，所述当所述PSCell的添加不是UE进入连接态以来第一次PSCell添加，也可以表述为当UE上有保存的S-MHI。
所述PSCell添加也可表述为SCG添加。
优选地，所述PSCell的添加指的是执行用于SCG的同步重配置(reconfigurationWithSync)且UE上此时没有被配置SCG。所述PSCell添加命令指的是包含了用于SCG的同步重配置的RRC消息且此时UE上没有被配置SCG。所述PSCell成功添加指的是当UE上之前未配置SCG时，当接收到并执行了包含在RRC消息中的用于SCG的同步重配置信息元素且MAC层成功完成了由此触发的随机接入过程。
可选地所述条目中还可以包括UE在所述时间内所对应的一个或多个PCell的小区标识。所述小区标识可以是全局小区标识或物理小区标识。
在上述实施例中，当UE执行在S-MHI中增加一个条目时，还可包括移除用于保存S-MHI的UE变量中最旧的条目。
实施例7
该实施例给出了一种UE离开RRC连接状态时的S-MHI处理方法。
作为一例，例如UE离开RRC连接状态时，若UE有保存的S-MHI，则丢弃所保存的S-MHI。
所述离开RRC连接状态可以是UE进入RRC空闲态。也可以是 UE进入RRC inactive状态，比如因为接收到用于挂起RRC连接的RRC释放消息。
实施例8
该实施例提出了一种UE释放SCG时的S-MHI记录方法。
作为一例，例如，当执行MR-DC或SCG的释放时若UE支持保存S-MHI，则UE在用于保存S-MHI的UE变量中增加一个条目，所述条目用于记录UE前一个PSCell的移动信息。所述条目中包括前一个PSCell的小区标识以及在该PSCell中所经历的时间。可选地，所述条目中还可以包括UE在被配置了该PSCell时所对应的PCell的小区标识。考虑到PCell切换时UE的PSCell可以不变更的场景，所述PSCell所对应的PCell可以是多于一个的。所述小区标识可以是全局小区标识或物理小区标识。
实施例9
该实施例提出了一种UE从RRC inactive通过RRC连接恢复过程进入RRC连接态的S-MHI记录方法。
该实施例可以适用于当UE在RRC恢复过程中接收到了包含restoreSCG信息元素的RRC恢复消息，且RRC恢复消息中指示了一个PSCell变更的情况。
作为一例，例如，当发生PSCell成功变更时，若UE支持保存S-MHI，则UE在用于保存S-MHI的UE变量中增加一个条目，所述条目用于记录UE前一个PSCell(即PSCell变更时的源PSCell)的移动信息。所述条目中包括前一个PSCell的小区标识以及在该PSCell中所经历的时间。所述在PSCell中所经历的时间是从该PSCell被添加到此次PSCell变更的时间，包括UE处于RRC inactive状态时所保存的UE非激活态接入层上下文中的PSCell为该PSCell的时间。可选地，所述条目中还可以包括UE在被配置了该PSCell时所对应的PCell的小区标识。考虑到PCell切换时UE的PSCell可以不变更的场景， 所述PSCell所对应的PCell可以是多于一个的。所述小区标识可以是全局小区标识或物理小区标识。
所述PSCell变更指的是执行了用于SCG的同步重配置(reconfigurationWithSync)，优选地，还包括PSCell不是同一个(同步重配置中的PSCell标识不同于之前的PSCell标识)。所述PSCell变更命令指的是包含了用于SCG的同步重配置的RRC消息。所述PSCell成功变更指的是当用于SCG的同步重配置信息元素包含在所述RRC消息中且MAC层成功完成了由此触发的随机接入过程。
实施例10
该实施例提出了一种UE从RRC inactive通过RRC连接恢复过程进入RRC连接态的S-MHI记录方法。
该实施例可以适用于当UE在RRC恢复过程中接收到了不包含restoreSCG信息元素的RRC恢复消息的情况。
作为一例，例如，当接收到RRC恢复消息时，若该消息中不包含restoreSCG信息元素，UE执行MR-DC相关配置的释放，释放MR-DC或SCG。当执行MR-DC或SCG的释放时若UE支持保存S-MHI，则UE在用于保存S-MHI的UE变量中增加一个条目，所述条目用于记录UE前一个PSCell的移动信息。所述条目中包括前一个PSCell的小区标识以及在该PSCell中所经历的时间。所述在PSCell中所经历的时间是从该PSCell被添加到此次PSCell被释放所经历的时间，包括UE处于RRC inactive状态时所保存的UE非激活态接入层上下文中的PSCell为该PSCell的时间。可选地，所述条目中还可以包括UE在被配置了该PSCell时所对应的PCell的小区标识。考虑到PCell切换时UE的PSCell可以不变更的场景，所述PSCell所对应的PCell可以是多于一个的。所述小区标识可以是全局小区标识或物理小区标识。
实施例11
该实施例提出了一种UE从RRC inactive进入RRC连接态后发生 的第一个PSCell变更时的S-MHI记录方法。
该实施例可以适用于UE在RRC恢复过程中执行了MR-DC/SCG的恢复但并没有变更PSCell，在后续接收到了包含在RRC重配置消息中的PSCell变更命令的情况。即当UE在RRC恢复过程中接收到了包含restoreSCG信息元素的RRC恢复消息，但RRC恢复消息中并不包含用于SCG的同步重配置，而是在后续接收到了RRC重配置消息中包含了用于SCG的同步重配置。
作为一例，例如，当发生PSCell成功变更时，若UE支持保存S-MHI，则UE在用于保存S-MHI的UE变量中增加一个条目，所述条目用于记录UE前一个PSCell(即PSCell变更时的源PSCell)的移动信息。所述条目中包括前一个PSCell的小区标识和在该PSCell中所经历的时间。当所述PSCell的变更是UE通过RRC恢复过程进入RRC连接状态以来的第一次PSCell变更，所述在PSCell中所经历的时间是从该PSCell被添加到此次PSCell变更的时间，包括UE处于RRC inactive状态时所保存的UE非激活态接入层上下文中的PSCell为该PSCell的时间。所述RRC连接被恢复以来电可表述为所述UE进入到RRC连接态以来。所述UE进入RRC连接状态以来的第一次PSCell变更也可表述为从UE接收到RRC恢复消息之后所接收到的第一个用于SCG的同步重配置，优选地，所述同步重配置中包含了新的PSCell标识(指示了PSCell的变更)。
可选地，所述条目中还可以包括UE在被配置了该PSCell时所对应的PCell的小区标识。考虑到PCell切换时UE的PSCell可以不变更的场景，所述PSCell所对应的PCell可以是多于一个的。所述小区标识可以是全局小区标识或物理小区标识。
所述PSCell变更指的是执行了用于SCG的同步重配置(reconfigurationWithSync)，优选地，还包括PSCell不是同一个(同步重配置中的PSCell标识不同于之前的PSCell)。所述PSCell变更命令指的是包含了用于SCG的同步重配置的RRC消息。所述PSCell成功变更指的是当用于SCG的同步重配置信息元素包含在所述RRC消 息中且MAC层成功完成了由此触发的随机接入过程。
实施例12
该实施例给出了一种S-MHI上报时的S-MHI记录方法。
当UE执行S-MHI的上报时，若UE此时没有被配置DC/SCG/PSCell，UE在用于保存S-MHI的UE变量中或所述用于上报S-MHI的消息中增加一个条目，所述条目用于记录UE上报S-MHI前处于无SCG/PSCell配置状态所经历的时间。
所述UE执行S-MHI上报时指的时UE通过RRC消息向网络侧上报所记录的S-MHI信息。一般，所述RRC消息是UEInformationresponse消息。UE在收到网络侧的S-MHI上报请求后向网络侧上报所述信息，所述请求为在用于请求S-MHI上报的RRC消息如UEInformationRequest消息中包含一个请求指示信息来实现。
在上述实施例中，当UE执行在S-MHI中增加一个条目时，还可包括移除用于保存S-MHI的UE变量中最旧的条目。
实施例13
该实施例提出了一种S-MHI记录方法。
在该实施例中，当发生PSCell添加/变更/释放时，UE记录所发生事件的绝对时间。例如UE在T1时刻被配置添加PSCell，则T2时刻被配置执行PSCell变更为PSCell2，在T3时刻被配置释放PSCell2及SCG。UE在S-MHI中记录PSCell1的时间信息为T1和T2，PSCell2的时间信息为T2和T3。即对于一个PSCell，前一个时间标识该小区被添加的时间，后一个时间标识该小区被释放或变更的时间或者UE执行S-MHI上报的时间。
考虑到UE处于RRC inactive状态的场景，例如UE在T1时刻被配置添加PSCell，则T2时刻被配置进入RRC inactive状态并保存了SCG配置，在随后的RRC连接恢复过程中，在T3时刻接收到了RRC连接恢复消息，对于不同的RRC恢复时的配置，(1)在T3时刻执行 SCG恢复且PSCell变更为PSCell2；(2)在T3时刻被配置释放PSCell2及SCG；(3)在T3时刻被配置恢复SCG配置但PSCell未变更，在之后T4时刻执行了PSCell1的变更或释放。UE在S-MHI中记录PSCell1的时间信息为T1，T2，T3，T4。即对于一个PSCell1，前一个时刻T1标识该小区被添加的时间，其中一个时刻T2标识该小区被保存/挂起进入RRC inactive的时间，其中一个时间T3标识该小区RRC被恢复进入RRC连接的时间；后一个时间T4标识该小区被释放或变更的时间。T3和T4可以是相同的，可选地，此时T4/T3可以不存在。
