In NR, N takes the value 1 or 2.
  • Target SCG configuration parameters In order to change the service PSCell to Cell A, the UE needs to apply the package Configuration parameters of the SCG containing the target PSCell (i.e. Cell A).

  • the trigger condition for applying SCG reconfiguration parameters is generally: the signal quality of the target PSCell is greater than the specified threshold and reaches the preconfigured time. Because the UE has not served PSCell at this time, the signal quality of the target PSCell cannot be compared with The signal quality of the serving PSCell is compared.
  • CPC can also use the same trigger condition as CPA, that is, the signal quality of the target PSCell is greater than the specified threshold for a preconfigured time. At this time, when changing the PSCell, the signal quality of the serving PSCell is no longer considered, but only the signal quality of the target PSCell is considered.
  • This evaluation condition is generally used when the serving cell is heavily loaded; at this time, even if the signal quality of the serving PSCell is very good, the NW hopes to change the UE's PSCell to reduce the service load of the serving PSCell.

CG配置：此消息用于传输SgNB或SeNB生成的SCG无线电配置。CU还可以使用它来请求DU执行某些操作，例如请求DU执行新的低层配置。(CG-Config:This message is used to transfer the SCG radio configuration as generated by the SgNB or SeNB.It can also be used by a CU to request a DU to perform certain actions，e.g.to request the DU to perform a new lower layer configuration.)

2、条件主辅小区组添加或变更过程(Conditional PSCell Addition or Change，CPAC)；
(1)条件主辅小区添加(Conditional PSCell Addition，CPA)
条件主辅小区添加是UE评估执行条件并在执行条件满足后执行的主辅小区添加。
CPA配置包含CPA候选小区的配置和执行条件。执行条件可能包含一个到两个触发条件。一旦成功完成主辅小区添加过程，UE释放所有存储的CPA配置。
(2)条件主辅小区变更(Conditional PSCell Change，CPC)
条件主辅小区变更是UE评估执行条件并在执行条件满足后执行的主辅小区变更。UE接收到CPC配置后开始评估执行条件。UE在主辅小区变更触发后停止评估执行条件。
CPC配置包含CPC候选小区的配置和执行条件。执行条件可能包含一个到两个触发条件。一旦成功完成主辅小区变更过程，UE释放所有存储的CPC配置。
CPC包括多种场景，如：
辅节点内主辅小区条件变更(Intra-SN CPC)
主节点发起的辅节点间主辅小区条件变更(MN initiated Inter-SN CPC)；
辅节点发起的辅节点间主辅小区条件变更(SN initiated Inter-SN CPC)；
3、条件主辅小区变更(Conditional PSCell Change，CPC)的配置
NW(NetWork)给双连接UE预配置CPC配置，由UE评估执行条件是否满足。一旦执行条件满足，UE将应用预配置的目标SCG(Secondary Cell Group，辅小区组)配置，进行PSCell变更。
CPC配置包括：
a.执行条件：即PSCell变更的执行条件，由N个测量标识(Measurement id)组成。每一个测量标识对应一个测量事件，当UE对候选小区Cell A的测量结果满足预设条件，则触发测量事件。当一个执行条件所包含的N个Measurement id对应的测量事件均被触发，则UE将服务PSCell变更为Cell A，简称CPC被触发。在NR中，N取值为1或2。
b.目标SCG的配置参数：为了将服务PSCell变更为Cell A，UE所需要应用的包 含目标PSCell(即Cell A)的SCG的配置参数。在新空口(New Radio，NR)中，目标SCG的重配置参数由包含同步重配指示(ReconfigurationWithSync IE)的RRC重配消息承载。该配置中包括目标PSCell的标识，部分配置可以通过delta config(即仅提供与服务SCG不同的参数)的方式提供。
c.CPC配置ID：一个执行条件和一组目标SCG的配置参数合起来可以用于针对一个候选PSCell的CPC过程。如果有N个候选小区，可以配置N个执行条件和N组目标SCG的配置参数，供UE同时进行评估。根据评估结果，确定最终的目标PSCell。针对一个PSCell的一个执行条件和一组目标SCG的配置参数通过CPC配置标识来关联；即关联到同一个CPC配置标识的一个执行条件和一组目标SCG的配置参数是针对一个候选PSCell的。
以NR中的参数为例：
condReconfigId指示CPC配置ID；condExecutionCond用于配置PSCell变更的执行条件，condRRCReconfig用于配置目标SCG的配置参数。三个参数组成一组CPC配置，用于针对一个候选PSCell的条件重配/条件主辅小区变更。
在CPC的配置中，应用到的measurement id，是通过测量配置参数通知给UE的。测量配置包括如下参数：
a.测量对象(Measurement Object，MO)：即待测量的频点；
b.上报配置(ReportConfig)：包含测量事件的触发条件，即指示当目标PSCell的信号质量满足何种预设条件(由测量事件的类型和门限参数决定)时，对应测量事件被触发。例如：候选PSCell的RSRP比当前服务PSCell的RSRP高3dB，且持续达到100ms时，被触发。(候选小区质量高于服务小区为上报配置中指示应用A3事件，3dB和100ms是上报配置中指示的门限参数)；
c.Measurement id(measId)：测量标识，用于关联一个MO和一个事件触发条件。
在NR中，三者通过如下方式关联在一起：
在相关技术的CPC过程中，流程如下：
(1)DC UE接收和保存NW侧下发的测量和CPC配置，并开始CPC评估；
(2)一旦至少一个执行触发条件被满足，UE执行对应的PSCell变更过程；
(3)一旦UE成功接入目标PSCell(在目标PSCell成功完成RACH)，UE删除保存的所有CPC配置。
以下提供一个具体的例子帮助理解现有的CPC过程：
(1)UE接收NW侧提供的测量和CPC相关配置，包括以下两组CPC配置：
(2)UE进行测量评估，根据第一组配置，UE对F2频点上的CellA进行测量；根据第二组配置，UE对F1频点上的CellB进行测量；
(3)一旦至少一个执行触发条件被满足，UE执行对应的PSCell切换过程；
假设关联到CPC配置ID为1的执行触发条件先被触发，即UE测量到工作在F2频点上的CellA的RSRP比serving PSCell的RSRP高3dB，且持续达到100ms；也就是说，UE对CellA的测量结果满足CPC执行触发条件；则UE应用关联到CPC配置ID为1的目标SCG的配置参数，即应用CellA作为PSCell的SCG的配置，接入到目标PSCell，即CellA；
(4)一旦UE成功接入CellA(在目标PSCell/CellA成功完成RACH)，UE删除保存的CPC配置，即第一和第二组CPC配置。
可选的，NW(目标服务基站)给UE重新配置CPC参数，新配置的CPC参数可以与被删除的CPC参数相同或不同。
4、条件主辅小区添加(Conditional PSCell Addition，CPA)的配置
CPA和CPC的配置方法和执行过程类似，区别之处在于，在进行CPA评估时，应用SCG重配置参数的触发条件一般是：目标PSCell的信号质量大于指定门限达到预配置时间。因为此时UE还没有serving PSCell，因此目标PSCell的信号质量无法与 serving PSCell的信号质量进行比较。
需要指出的是，CPC也可以使用与CPA相同的触发条件，即目标PSCell的信号质量大于指定门限达到预配置时间。此时，进行PSCell变更不再考虑服务(serving)PSCell的信号质量情况，仅考虑目标PSCell的信号质量。这种评估条件一般用在服务小区高负荷的情况；此时，即使服务PSCell的信号质量很好，NW也希望变更UE的PSCell，以降低服务PSCell的业务负荷。
如果发生无线链路失败(Radio Link Failure，RLF)或切换(如同步重配)失败(HandOver Failure，HOF)，或进行小区切换，UE可以通过重建或条件切换(UE在RLF或HOF之后，进行小区选择，如果所选到的小区恰好是条件切换(Conditional Handover，CHO)的候选PCell/MCG SpCell时)，与NW建立单连接，UE无法与NW建立双连接，导致数据速率降低。
因此，本申请实施例提供一种连接恢复方法、小区切换方法、及装置。

在一个实施例中，UE被配置了CHO配置1(对应主节点特殊小区为Cell1)和CHO配置2(对应主节点特殊小区为Cell2)；CPA配置1(对应辅节点特殊小区为Cell3)和CPA配置2(对应辅节点特殊小区为Cell4)。其中Cell1和Cell3可以被同时配置给UE进行DC传输，Cell1和Cell4不可以同时配置给UE进行DC传输(例如：Cell1和4所在的基站没有Xn接口)；则可以理解为：CHO配置1和CPA配置1相互关联；CHO配置1和CPA配置2不相互关联，在UE接收到上述CHO配置1、CHO配置2、CPA配置1、和CPA配置2以后：

可选地，只要存在一组第一目标CPAC配置所包括的执行条件满足，就可以切换为DC；反之(所有组)第一目标CPAC配置均不满足条件，就切换为单连接。
在一个实施例中，UE被配置了CHO配置1(对应主节点特殊小区为Cell1)和CHO配置2(对应主节点特殊小区为Cell2)；CPA配置1(对应辅节点特殊小区为Cell3)和CPA配置2(对应辅节点特殊小区为Cell4)。其中Cell1和Cell3可以被同时配置给UE进行DC传输，Cell1和Cell4不可以同时配置给UE进行DC传输(例如：Cell1和4所在的基站没有Xn接口)；则可以理解为：CHO配置1和CPA配置1相互关联；CHO配置1和CPA配置2不相互关联，在UE接收到上述CHO配置1、CHO配置2、CPA配置1、和CPA配置2以后：

可选地，在终端基于接收到的所述CHO配置包括的执行条件进行评估的情况下，进行小区选择过程，如果选择的小区为所述至少一组CHO配置中的第一目标CHO配置所配置的第一主节点特殊小区，则可以进一步再对与第一目标CHO配置相关联的第一目标CPAC配置包括的执行条件进行评估，若确定第一目标CPAC配置包括的执行条件满足，则可以应用第一目标CHO配置包含的主节点重配参数和第一目标CPAC配置包含的辅节点重配参数执行切换，切换成功(如在第一主节点特殊小区和第一辅 节点特殊小区均成功完成随机接入)后，终端以DC方式同时通过第一主节点特殊小区和第一辅节点特殊小区与网络通信。
在一个实施例中，UE被配置了CHO配置1(对应主节点特殊小区为Cell1)和CHO配置2(对应主节点特殊小区为Cell2)；CPA配置1(对应辅节点特殊小区为Cell3)和CPA配置2(对应辅节点特殊小区为Cell4)。其中Cell1和Cell3可以被同时配置给UE进行DC传输，Cell1和Cell4不可以同时配置给UE进行DC传输(例如：Cell1和4所在的基站没有Xn接口)；则可以理解为：CHO配置1和CPA配置1相互关联；CHO配置1和CPA配置2不相互关联，在UE接收到上述CHO配置1、CHO配置2、CPA配置1、和CPA配置2以后：
1.UE保存接收到的配置，并开始进行CHO评估；
2.UE发生RLF或HOF(例如：UE在切换目标主节点特殊小区随机接入失败或未成功完成)，UE进行小区选择过程，选择了Cell 1(对应CHO配置1)；UE开始对CHO配置1关联的CPA配置1包括的执行条件进行CPA评估，如果与CHO配置1关联的CPA配置1所配置的特殊小区Cell 3满足CPA触发条件(即执行条件)，则UE应用CHO配置1/Cell 1对应的主节点重配参数的取值和CPA配置1/Cell 3对应的辅节点重配参数的取值执行切换。
3.切换成功(如在第一主节点特殊小区Cell 1和第一辅节点特殊小区Cell 3均成功完成随机接入)后，UE以DC方式同时通过Cell1，Cell 3与网络通信。
在一个实施例中，UE被配置了CHO配置1(对应主节点特殊小区为Cell1)和CHO配置2(对应主节点特殊小区为Cell2)；CPC配置1(对应辅节点特殊小区为Cell5)和CPC配置2(对应辅节点特殊小区为Cell5)。其中Cell1和Cell5可以被同时配置给UE进行DC传输，Cell1和Cell6不可以同时配置给UE进行DC传输(例如：Cell1和6所在的基站没有Xn接口)；则可以理解为：CHO配置1和CPC配置1相互关联；CHO配置1和CPC配置2不相互关联，在UE接收到上述CHO配置1、CHO配置2、CPC配置1、和CPC配置2以后：

3.切换成功(如在第一主节点特殊小区Cell 1和第一辅节点特殊小区Cell 5均成功完成随机接入)后，UE以DC方式同时通过Cell1，Cell 5与网络通信。
本申请实施例中，UE在CHO的触发条件满足后，才进行CHO对应的CPAC评 估，降低了进行CPAC的数量。
例如，如果NW为UE配置2组CHO参数，每组CHO对应1组CPAC参数。UE确定了满足的CHO之后，才开始对应的CPAC评估，因此，需要评估的CPAC触发条件只有1组。因此UE所需进行的触发条件评估数量大大减少，降低了UE的复杂度。

在本申请中，通过仅评估已满足执行条件的CHO配置所关联的CPAC配置的执行条件，来达到降低待评估的CPAC执行条件梳理的目的，且对CPAC配置所包括的执行条件进行单次评估，克服相关技术中CPAC评估次数过多带来的计算复杂度较大，能耗较大的缺陷，可以进一步减小计算复杂度，节省能耗。
