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的相关技术进行说明，以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。
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之间紧密合作(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在2017年12底前首先完成第一个5G版本，即E-UTRA和NR双连接(E-UTRA-NR Dual Connectivity，EN-DC)。在EN-DC中，LTE基站(eNB)作为主节点(Master Node，MN)，NR基站(gNB或en-gNB)作为辅节点(Secondary Node，SN)。其中MN主要负责RRC控制功能以及通向核心网的控制面；SN可以配置辅助的信令，例如SRB3，主要提供数据传输功能。
在R15后期，将支持其他双连接(Dual Connectivity，DC)模式，即NR和E-UTRA双连接(NR-E-UTRA Dual Connectivity，NE-DC)，5GC-EN-DC，NR DC。对于EN-DC，接入网络连接的核心网是演进型分组核心网(Evolved Packet Core network，EPC)，而其他DC模式连接的核心网是5G核心网(5G Core Network，5GC)。
在多RAT双连接(Multi-RAT Dual Connectivity，MR-DC)中，通过SCG配置信息对SCG进行配置之后，SCG默认处于激活状态，此时SCG配置信息中包含同步重配置(ReconfigurationWithSync)，用于触发终端设备向PSCell发起随机接入过程。同步重配置的内容可以参照以下表1所示。

表1
SCG也可以处于去激活状态或者激活状态，SCG被去激活后进入去激活状态，SCG被激活后进入激活状态。SCG处于去激活状态相比较SCG处于激活状态来说，终端设备更加节能。
SCG处于去激活状态后，一方面，终端设备在PSCell上的行为并不清楚。另一方面，在SCG去激活过程中，终端设备和PSCell之间可能会失去上行同步关系，例如控制上行同步的定时器如果超时，则表明终端设备和PSCell之间失去上行同步关系。如果终端设备时刻保持上行同步，需要频繁的进行随机接入过程来恢复上行同步，以及获取和网络之间好的波束之间的同步。这样做的坏处就是费电，但是如果不执行随机接入过程，就会导致终端设备和PSCell之间一直处于不同步的状态，进而导致SCG激活的时延增加。
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，明确了SCG去激活的场景下如何约束终端设备的行为。
本申请实施例的技术方案可以应用于双连接(DC)架构或者多连接(MC)架构。在DC架构中，有一个MCG和一个SCG。在MC架构中，有一个MCG和多个SCG。其中，MN侧的小区组称为MCG，SN侧的小区组称为SCG。本申请实施例对DC的类型不做限制，例如可以是MR-DC、EN-DC、NE-DC、NR-DC等等。本申请实施例对MC的类型也不做限制。
需要说明的是，本申请实施例中对于“MCG侧”的描述也可以称为“MN侧”，对于“SCG侧”的描述也可以称为“SN侧”。
