具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
本申请实施例描述的网络架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
请参考图1，其示出了本申请一个实施例提供的通信***的网络架构的示意图。该网络架构可以包括：终端10和基站20。
终端10的数量通常为多个，每一个基站20所管理的小区内可以分布一个或多个终端10。终端10可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端设备(terminal device)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端。
基站20是一种部署在接入网中用以为终端10提供无线通信功能的装置。基站20可以包括各种形式的卫星基站、宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的***中，具备基站功能的设备的名称可能会有所不同，例如在第5代移动通信(5th-Generation，5G)新空口(New Radio，NR)***中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称可能会变化。为方便描述，本申请实施例中，上述为终端20提供无线通信功能的装置统称为基站。
可选的，图1中未示出的是，上述网络架构还包括其它网络设备，比如：中心控制节点(Central Network Control，CNC)、接入和移动性管理功能(Access and Mobility Management Function，AMF)设备、会话管理功能(Session Management Function，SMF)或者用户面功能(User Plane Function，UPF)设备等等。
本公开实施例中的“5G NR***”也可以称为5G***或者NR***，但本领域技术人员可以理解其含义。本公开实施例描述的技术方案可以适用于5G NR***，也可以适用于5G NR***后续的演进***。
在介绍本申请后续各个实施例所示的方案之前，首先对本申请涉及的几个名词概念进行介绍。
双连接(Dual-Connectivity，DC)是第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)组织引入的重要技术。通过双连接技术，长期演进(Long Term Evolution，LTE)宏站和小站可以利用非理想回传(non-ideal backhaul)X2接口来实现载波聚合，从而为用户提供更高的速率，以及利用宏/微组网提高频谱效率和负载平衡。支持双连接的终端设备可以同时连接两个基站，增加单用户的吞吐量。
在5G网络的部署过程中，5G小区既可以作为宏覆盖独立组网，也可以作为小站对现有 的LTE网络进行覆盖和容量增强。无论采用哪种组网方式，双连接技术都可以用来实现LTE-5G***的互连，从而提高整个移动网络***的无线资源利用率，降低***切换的时延，提高用户和***性能。3GPP组织在LTE双连接技术基础上，定义了LTE和5G的双连接技术。LTE-5G双连接是运营商实现LTE和5G融合组网、灵活部署场景的关键技术。在5G早期可以基于现有的LTE核心网实现快速部署，后期可以通过LTE和5G的联合组网来实现全面的网络覆盖，提高整个网络***的无线资源利用率、降低***切换时延以及提高用户和***性能。
当前，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 Communication，URLLC)、大规模机器类通信(Massive Machine Type Communication，mMTC)。
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，便如室内，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EN-DC(LTE-NR Dual Connectivity，LTE-NR双连接)。这里LTE作为MN(主节点，Master Node)，NR作为SN(辅节点，Secondary Node)。
其中MN节点主要的无线资源控制(Radio Resource Control，RRC)控制功能以及通向核心网(Core Network，CN)的控制面，SN节点可以配置辅助的信令，例如信令无线承载(Signaling Radio Bearer，SRB)3，主要提供数据传输功能。
在R15后期，将支持其他DC模式，即NR和演进的通用无线接入(Evolved Universal Terrestrial Radio Access，E-UTRA)双连接(NR-E-UTRA Dual Connectivity，NE-DC)，5G核心网(5G Core Network，5GC)E-UTRA和NR双连接(5GC-EN-DC)，和NR DC。对于EN-DC，接入网络连接的核心网是EPC，而其他DC模式连接的核心网是5GC。
从终端角度，MR-DC场景下用户面协议栈结构如图2和图3所示。其中，图2示出了EN-DC场景下终端侧协议栈架构，核心网为演进型分组核心网(Evolved Packet Core network，EPC)；图3示出了下一代E-UTRA和NR双连接(NG-RAN E-UTRA-NR Dual Connectivity，NGEN-DC)、NE-DC或者NR-DC场景下终端侧协议栈架构，核心网为5GC。
处于MR-DC下的终端存在三种类型的无线承载(Radio Bearer)，分别为主小区组(Master Cell Group，MCG)承载(MCG bearer)，辅小区组(Secondary Cell Group，SCG)承载(SCG bearer)和***承载(split bearer)。当一个无线承载的RLC，介质访问控制(Media Access Control，MAC)，物理层(Physical，PHY)协议栈位于MN的时候，这样的无线承载称为MCG bearer，反之称为SCG bearer。Split bearer在MN和SN上都有无线链路，但是只有一个PDCP协议栈，可能在MN侧，也可能在SN侧。Split bearer的目的是为了提高无线接口的流量。当PDCP层允许对PDCP数据包在不同链路之间进行重发的时候，split bearer还可以提高无线承载的可靠性。
