应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
为便于理解本申请实施例的技术方案，以下对本申请实施例相关的技术方案进行说明。
随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性，为此第三代合作伙伴计划(3 rd Generation Partnership Project，3GPP)国际标准组织开始研发5G。5G的主要应用场景为：增强移动超宽带(enhanced Mobile Broadband，eMBB)、低时延高可靠通信(Ultra-Reliable Low-Latency Communications，URLLC)、大规模机器类通信(massive Machine-Type Communications，mMTC)。
一方面，eMBB仍然以用户获得多媒体内容、服务和数据为目标，其需求增长十分迅速。另一方面，由于eMBB可能部署在不同的场景中，例如室内，市区，农村等，其能力和需求的差别也比较大，所以不能一概而论，必须结合具体的部署场景详细分析。URLLC的典型应用包括：工业自动化，电力自动化，远程医疗操作(手术)，交通安全保障等。mMTC的典型特点包括：高连接密度，小数据量，时延不敏感业务，模块的低成本和长使用寿命等。
在NR早期部署时，完整的NR覆盖很难获取，所以典型的网络覆盖是广域的LTE覆盖和NR的孤岛覆盖模式。而且大量的LTE部署在6GHz以下，可用于5G的6GHz以下频谱很少。所以NR必须研究6GHz以上的频谱应用，而高频段覆盖有限、信号衰落快。同时为了保护移动运营商前期在LTE投资，提出了LTE和NR之间紧耦合(tight interworking)的工作模式。
为了能够尽快实现5G网络部署和商业应用，3GPP首先完成第一个5G版本，即EN-DC(LTE-NR Dual Connectivity)。在R15后期，将支持其他DC模式，即NE-DC，5GC-EN-DC，NR DC。在EN-DC中，LTE基站作为主节点(Master Node，MN)，NR基站作为辅节点(Secondary Node，SN)，LTE基站和NR基站连接EPC核心网。在NE-DC中，NR基站作为MN，LTE基站作为SN，NR基站和LTE基站连接5GC核心网。在5GC-EN-DC中，LTE基站作为MN，NR基站作为SN，LTE基站和NR基站连接5GC核心网。在NR DC中，一个NR基站作为MN，另一个NR基站作为SN，两个NR基站连接5GC核心网。
在R16中，引入了网络侧基于终端设备上报的测量结果配置切换条件以及待切换的目标小区，来使得终端设备根据自己的测量结果内部判断是否满足网络侧配置的切换条件，如果满足则终端设备自主切换到预先配置的目标小区，避免了终端设备由于切换命令发不下来或者测量报告发不上去而导致的切换失败问题。
同时R16还支持基于网络侧配置的条件配置以及目标主辅小区(Primary Secondary Cell，PSCell)配置，来实现基于条件的PSCell变更，但是此时的PSCell变更是不影响MN的。其中，条件配置和目标PSCell配置由SN产生并配置给终端设备。
对于SN内(intra-SN)的PSCell变更(简称为intra-SN PSCell变更)，存在不影响MN和影响MN两种场景，另一方面，同时还存在MN初始(MN initiated)和SN初始(SN initiated)两种场景。图2-1为MN初始的SN调整流程(SN Modification procedure)，图2-2为SN初始的且影响MN的SN调整流程(SN Modification procedure)，图2-3为SN初始的且不影响MN的SN调整流程(SN Modification procedure)。需要说明的是，SN调整流程具体是指intra-SN PSCell变更流程。
对于SN间(inter-SN)的PSCell变更(简称为inter-SN PSCell变更)，存在MN初始和SN初始两种场景。图3-1为MN初始的SN变更流程(SN change procedure)，图3-2为SN初始的SN变更流程(SN change procedure)。需要说明的是，SN变更流程具体是指inter-SN PSCell变更流程。
目前，NR并不支持基于条件的影响MN的intra-SN PSCell变更，也不支持基于条件的inter-SN PSCell变更(也可以称为基于条件的inter-SN SN变更)，也不支持基于条件的SN添加。为此，提出了本申请实施例的以下技术方案，本申请实施例的技术方案能够通过MN和SN之间的协商来使得标准中支持上述场景。
