为详细说明本申请实施例提供的CPAC的评估方法，以下将结合几个具体的实施例进行说明。
实施例一
该实施例包括如下步骤：
步骤1：MN给UE配置了CPA配置和CPC配置，并指示UE可以在CPA后继续进行CPC的评估。
该指示可以在条件重配置(ConditionalReconfiguration)中，如放在CondReconfigToAddMod-r18中。
其中CPA配置包括了多个候选PSCell以及对应的测量事件和门限等。
CPC配置包括了多个候选PSCell以及对应的测量事件和门限等，并且关联了PSCell标识，该标识指当前PSCell为具体哪一个。
步骤2：UE发现CPA候选PSCell 1满足条件，执行CPA，添加了PSCell 1。此时，UE释放CPA配置，并基于关联了PSCell 1的CPC配置，继续评估CPC。
步骤3：UE发现CPC候选PSCell 2满足条件，执行CPC，PSCell由PSCell 1变更为PSCell 2。
实施例二
该实施例包括如下步骤：
步骤1：MN给UE配置了CPC配置。
CPC配置包括了多个候选PSCell以及对应的测量事件和门限等，其中PSCell 1关联的事件为A3，PSCell 2关联的事件为A4或B1，PSCell 3关联的事件为A5。
步骤2：UE发现CPC候选PSCell 1满足条件，执行CPC，由当前PSCell变更到PSCell 1。此时，UE释放关联事件为A5的PSCell 3相关的CPC配置，并基于关联的事件为A4的PSCell 2的配置，继续评估CPC。
步骤3：UE发现CPC候选PSCell 2满足条件，执行CPC，PSCell由PSCell 1变更为PSCell 2。
实施例三
该实施例主要介绍执行条件的配置方法，以下分情况1和情况2进行介绍。
情况1：网络侧给UE的CPAC配置中，包括测量门限1，测量门限2，测量门限3。
当UE未执行CPAC时，使用测量门限1判断UE何时执行CPAC。每执行一次CPAC，后续的CPAC评估则使用新的测量门限来评估。
情况2：网络侧给UE的CPAC配置中，PSCell 1配置关联了事件A3+A4，PSCell 2配置关联了事件A5。则对于PSCell 1，既可以作为CPA的候选小区也可以作为CPC的候选小区，进行连续的CPAC评估；而对于PSCell 2，只能作为CPC的候选小区，且在UE执行完CPAC后，需要释放该配置。
图3是本申请实施例的CPAC配置的处理方法实现流程示意图，可以应用在终端。如图3所示，该方法300包括如下步骤。
