技术领域
本发明涉及移动通信技术领域，尤其涉及一种无线链路管理的方法及装置、系统、计算机存储介质。
背景技术
对于任何一种蜂窝移动系统，无论其背后具体的无线接入技术(RAT，Radio Access Technology)是什么，它通常都是由蜂窝网基本网元节点(如核心网CN、网关Gateway、集中控制器CU、基站BS、分布式节点DU)，终端UE，和提供移动通信无线链路服务的最基本覆盖单元服务小区Cell或者服务波束Beam所组成。图1是某蜂窝移动系统中，由宏微基站(对应着宏微小区)构成的蜂窝网络示意图，Cell下行覆盖反映了：基站节点(比如：eNB，gNB，TRP等)可实现下行传输效果可控下的有效传输范围；Cell下行负荷反映了：基站节点当前下行空口无线资源被使用和占用的程度；Cell上行覆盖反映了：终端可实现上行传输效果可控下的有效传输范围，和下行覆盖可能不同；Cell上行负荷反映了：基站节点当前空口上行无线资源被使用和占用的程度，和下行负荷可能不同。随着日益增加的蜂窝移动用户数目和大量的各类数据业务的接入传输需求，运营商们常常通过低功率节点(LPN，Low Power Node)或称为微小区(Small Cell)来组 网进行热点区域覆盖；LPN又称为微小区或者小小区，LPN的覆盖范围远远小于宏小区，通常被异频部署的宏小区伞状重叠覆盖着。
下面将以4G长期演进(LTE，Long Term Evolution)蜂窝移动系统为例，它包括演进的通用陆地无线接入网(E-UTRAN，Evolved Universal Terrestrial Radio Access Network)以及核心网CN(比如移动管理实体(MME，Mobility Management Entity)、服务网关(SGW，Serving Gateway)。E-UTRAN包括众多的演进基站(eNB，evolved Node B)，它和CN之间通过S1接口连接，eNB之间可通过X2接口连接。单个eNB可以管理一个或多个服务小区，通过空中接口Uu为终端UE提供上下行数据传输服务，LTE的系统架构和接口如图2所示。MME和eNB为终端UE提供各类通信业务，分配相关的无线资源，配置对应的数据无线承载(DRB，Data Radio Bearer)。主控锚点基站eNB为终端UE建立唯一一条无线资源控制层(RRC，Radio Resource Control)信令无线承载(SRB，Signaling Radio Bearer)，对UE进行无线管理和配置等。为了在UE移动过程中，实现维持各条DRB相关联的业务服务质量(QOS，Quality of Service)保持连续性，为了实现eNB间上下行无线资源的均衡化/合理化被使用，eNB通过特定的移动切换流程，来实现对终端UE在同质或者异质宏微服务小区间的移动性或无线资源聚合控制。
目前，LTE技术已经能够支持终端UE同时与宏小区和微小区建立无线链路，同时进行上下行数据的传输，称为LTE双连接(DC，Dual Connectivity)技术；LTE DC技术的工作原理如图3所示，处于LTE DC双连接数据传输模式下的UE，能够同时与主控锚点基站(MeNB，Master eNodeB)和分流辅基站(SeNB，Secondary eNodeB)进行上下行的双工通信；其中MeNB是UE无线链路(RL，Radio Link)管理控制方面的主控锚点eNB，建立有RRC，负责UE的移动性和配置管理等，具有同时连接上游核心网节点和下 游UE的功能；SeNB在逻辑上必须通过X2接口挂靠在MeNB下，为UE提供用户业务数据包分流传输相关的功能，用于聚合SeNB侧无线资源，增强用户数据传输率，提升系统容量和上下行的业务负荷分布等。可以简单地理解为：UE与LTE核心网的移动管理实体MME之间的非接入层控制信令(NAS，Non Access Stratum)交互只能通过MeNB实现，UE与LTE接入网的接入层控制信令(AS，Access Stratum)交互也只能通过MeNB实现；UE与LTE核心网和接入网的用户业务数据包的传输交互既可以通过MeNB侧MCG RL实现，也可以同时通过SeNB侧的SCG RL实现；而SeNB与核心网MME或者UE进行RRC控制信令AS交互之时，必须通过主控锚点MeNB的中转处理来实现，而不能直接通过SCG RL实现。LTE DC技术支持三种基本的数据无线承载类型(DRB Type)，如图4所示：其中图4左为：LTE DC无线主承载MCG Bearer(相当于单连接数据传输模式下的无线承载)，通过聚合MeNB侧的服务小区组(MCG，Master Cell Group)来实现用户业务数据包的上下行传输；图4中为：LTE DC无线分割承载Split Bearer，通过聚合MeNB和SeNB两侧的MCG和SCG同时实现用户业务数据包的上下行传输；图4右为：LTE DC无线辅承载SCG Bearer，通过聚合SeNB侧的服务小区组(SCG，Secondary Cell Group)来实现用户业务数据包的上下行传输。
4G LTE蜂窝网络运营数年之后，随着各行各业不同种类的用户业务数据包传输需求的爆发式增长和拓展衍生，5G New RAN(包括基于LTE演进的eLTE系统和革命全新的NR(New Radio)系统)系统正在研究设计和标准制定中。和传统的3G UMTS与4G LTE移动蜂窝通信系统相比，5G蜂窝系统面向的应用场景差异性非常大。在未来5G移动网络中，不仅仅需要提供人与人之间的通信，还要为各式各样的物联网海量设备提供各式各样的服务。利用5G移动网络，虚拟现实、高清视频等有超高数据传输速率 需求的业务，或者车联网无人驾驶，远程医疗手术等有着低延时超可靠传输服务需求的业务，以及在小型物联网终端的密集度方面，与现有移动网络相比，在传输速率、单用户上下行速率、端到端的时延、以及每平方米能够接入的终端UE数量等方面都会有巨大的提升。
为了更好地协同利用好4G LTE和5G New RAN(后续5G相关无线节点将用NR gNB简单说明表示)两张相对独立的蜂窝移动网资源，运营商未来将会在4G/5G/WLAN异构系统网络混合部署的场景环境下(即不同频点或不同区域部署着不同的LTE eNB，eLTE eNB和NR gNB，WLAN AP宏微基站)，通过类似LTE DC紧耦合双连接的方式，把两个或者更多的同构/异构基站节点的无线资源聚合连接在一起使用，这样UE可以同时和两个或者更多的同构/异构基站节点建立维护无线连接(后续简称为：多连接数据传输模式)，共同承担着用户业务数据包的上下行传输。类比上述图3中的LTE DC技术工作原理，多连接数据传输模式原理可以如图5所示。相比图3，图5中核心网节点更换为5G的NGC(Next Generation Core)，仍然分离为控制面实体NGC-C(类比MME)和用户面实体NGC-U(类比SGW)，另外核心网网元和无线接入网元gNB/eNB之间的接口更换为NG，做多连接数据传输紧耦合的基站节点个数从2个拓展为多个(即大于2个)，但其中仍然有一个主控锚点Master node(可以由eNB或者gNB担当)，有多个辅节点Secondary nodes(可以由eNB或者gNB或者WLAN AP担当)，基站节点间的接口更换为Xn(类比X2)，空口Uu仍然分离为传输RRC控制信令的Uu-C(对应着SRB承载)和传输用户业务数据包的Uu-U(对应着DRB承载)。
过去和现在，无论4G时代的LTE DC技术还是5G时代的NR异构多连接数据传输技术，其工作原理的核心点为：只有1个Master node主控锚点基站去聚合控制管理1个或者多个Secondary node分流辅基站的分流节 点，因此所有Secondary node分流节点上的无线链路配置和资源分配状况都需要经过Master node主控锚点基站的控制和管理确认，比如需要检查确认某Secondary node分流辅基站给出的无线链路配置和资源状况是否和Master node主控锚点基站侧的策略相冲突；是否主辅基站聚合在一起的总配置冲突超出了UE的总硬软件能力范围；Secondary node分流辅基站在移动管理(切换)方面，通常只有被动的响应能力，不具备独立自主的控制选择权。
除此之外，当前多连接数据传输模式存在下列多种运行约束限制：
1：在Master node主控锚点基站侧的无线链路(MCG RL)发生移动改变(切换)的过程中，Secondary node分流辅基站侧的所有无线链路(SCG RLs)都会受到被动的影响，不仅MCG Bearers上正在承载的上下行数据传输中断(待MCG RL成功切换后才能恢复数据传输)，所有SCG RLs即使没发生移动改变(切换)，所有SCG Bearers上承载的上下行数据传输也必须都被迫中断(待MCG RL成功切换后，SCG Bearers配置得到相应的重置才能恢复数据传输)，这个切换过程中，UE和网络侧的上下行数据传输彻底中断，需要一段时间来重建恢复，很大程度降低了用户通讯体验。
2：当Master node主控锚点基站侧的无线链路(MCG RL)发生移动切换失败的时候，Secondary node分流辅基站侧所有的SCG RLs相关的资源和配置也要自动被迫释放掉，之后再待Master node主控锚点基站尝试RRC连接重建和多连接传输模式的恢复，上述过程不仅需要消耗一定的空口和地面接口信令资源，还会带来更大的数据传输中断延时，更大程度降低了用户通讯体验。
3：当Master node主控锚点基站侧的无线链路(MCG RL)发生本地链路失败(MCG RLF)的时候，Secondary node分流辅基站侧的所有无线链路(SCG RLs)都会受到被动影响，不仅MCG Bearers上正在承载的上下 行数据传输中断(待MCG RL成功恢复建立后才能恢复数据传输)，所有SCG RLs即使没发生本地链路失败(SCG RLF)，所有SCG Bearers上承载的上下行数据传输也必须都被迫中断(待MCG RL成功恢复建立，SCG Bearers配置得到相应的重置后才能恢复数据传输)，此时UE和网络的数据传输彻底中断，需要一段时间来重建恢复，很大程度降低了用户体验。
上述机制原理的设计是面向同构同RAT系统内基站节点之间的，比如4G eNB基站之间，或者NR gNB基站之间。上述所有Secondary Node分流辅基站侧的SCG RLs都要受到Master Node主控锚点基站侧MCG RL状况的约束和影响，这在异构系统基站环境下，缺点和局限性被进一步放大，因为异构(不同RAT)基站之间的彼此独立性更大。

本发明实施例中，所述方法还包括：
旧的主控锚点基站从UE的多连接配置中释放掉；

增强的主控锚点基站和辅控锚点基站辅控的UE异构多连接数据传输模式，可以使得异构多连接数据传输的控制管理更加地在不同RAT域之间分离和加强彼此的独立性鲁棒性，减少不必要的网络节点失败被删除后再重建而产生的地面接口和空中接口的信令开销，减轻用户通讯连接中断的体验，这对那些需要高可靠通讯连接的用户业务类型URLLC更有意义。

下面结合具体应用对本发明实施例的无线链路管理的方法做进一步详细描述。
本发明增强的多连接数据传输模式的原理如图6所示。相比于图5，本发发明实施例的技术方案的主要区别在于：
图5中只有一个Master Node1作为异构多连接数据传输的主控锚点基站，而图6中可以从和Master Node1不同RAT制式的异构Secondary node集合中，选择出一个特殊的Secondary node，进行附加配置后充当为辅控锚点Primary Secondary node2的角色。该辅控锚点相对于Master Node1仍然为Secondary node的逻辑关联角色， 因此Master Node1可以按照传统方式对Primary Secondary node2进行Secondary node相关的逻辑操作(比如添加/重配/删除等)。同时该辅控锚点Primary Secondary node2相对于其他普通的Secondary node，可以针对和Primary Secondary node2自己同构同RAT类型的Secondary nodes去实施类似Master Node1的逻辑控制角色， 因此Primary Secondary node2可以按照增强的方式，面向同构同RAT类型的Secondary nodes，分担原本Master Node1需要做的相关逻辑控制管理操作(比如添加/重配/删除等)。
Master Node1通过本地RRM算法，基于RRM测量结果/无线负荷等因素，从异构基站集合中选择出哪个Secondary node适合做Primary Secondarynode2，再通过基站节点间的接口Xn接口信令对Primary Secondary node2进行相关的增强配置，即Primary Secondary node2一方面需要和Secondarynode逻辑角色一样，完成原来必要的分流辅基站分流节点的相关配置， 同时还要承担附加的辅控锚点的增强角色，完成必要的辅控锚点基站的相关附加配置。
在完成Primary Secondary node2的配置过程中，Master Node1需要通过Uu空中接口RRC信令对UE进行Primary Secondary node2相关的增强配置，即UE需要和Primary Secondary node2一方面建立普通Secondary node的逻辑关联，完成原来必要的分流辅基站分流无线链路的相关配置， 同时还要 和辅控锚点建立增强的逻辑关联，完成必要的辅控锚点基站无线链路的相关附加配置。
Primary Secondary node2类似Master Node1，它和核心网网元NGC有独立的控制面连接NG-C2和用户面连接NG-U2(Primary Secondary)，在主控锚点基站控制面NG-C1正常工作状态下，NG-C2也可以处于激活的正常工作状态，NG-C2可以用来传输核心网相关的NG接口信令；NG-U2(Primary Secondary)可以和其他普通的NG-U(Secondary)一样处于激活的正常工作状态，用来传输来去核心网的上下行用户面业务数据包。
Primary Secondary node2类似Master Node1，它和UE有独立的Uu-C2空中接口的RRC连接和用户面Uu-U2(Primary Secondary)的无线链接，同时Uu-C2可以和Uu-C1一样处于激活的正常工作状态，同时用来传输Master Node1和Primary Secondary node2各自相关的RRC信令；Uu-U2(Primary Secondary)可以和其他普通的Uu-U(Secondary)一样处于激活的正常工作状态，同时传输来去空中接口Uu的上下行用户业务数据包。
当Master Node1确定且配置了特定目标Secondary node做为Primary Secondary node2之后，需要通过Uu-C1空中接口RRC信令对UE进行和Primary Secondary node2相关的附加配置。UE一方面需要把Primary Secondary node2视为普通的Secondary node逻辑角色，完成必要的SCG RL相关配置和资源预留协同，同时还要把Primary Secondary node2视为辅控锚点基站的逻辑角色，完成附加的Primary SCG RL相关配置和资源预留协同。
当Master Node1确定且配置了特定目标Secondary node作为Primary Secondary node2之后，Master Node1可以仅仅维护控制管理和自己同构同RAT的普通Secondary nodes；而让Primary Secondary node2独立去维护控制管理和它同构同RAT的普通Secondary nodes；此时所有做多连接的异构基站被划分到不同的RAT域中，被各自RAT域内的控制锚点所控制管理， 实现控制管理的分离。
Primary Secondary node2作为辅控锚点基站，也可以对属于同构同RAT域中的普通的Secondary node和SCG RL施加类似Master Node1的相关控制管理操作，比如普通Secondary node和SCG RL的添加、删减、重配，UE服务小区集合的改变，无线链路资源重配等。当Primary Secondary node2成功完成某次控制管理操作后，需要通过Xn-C接口向Master Node1报告控制管理操作的结果，以和Master Node1实现相关配置信息的同步更新。
当Master Node1侧发生MCG RL本地失败或者移动切换失败的时候，Master Node1可以根据RRM算法或者特定需要，让Primary Secondary node2升级成为新的主控锚点基站的角色，逻辑上成为新的Master Node1，让NG-C2承担原来NG-C1的角色任务，且保持原来激活且正常工作的Uu-C2，并让其承担原来Uu-C1的角色任务。原来旧的Master Node1节点可以从UE多连接配置中被释放删除掉，也可以继续被维护为普通的Secondary node，或者被维护为新的Primary Secondary node2，后续继续控制管理同构同RAT域中的普通的Secondary node(因为旧的Primary Secondary node2已经被升级为了新的Master Node1)。
如果旧的Master Node1节点被从UE的多连接配置中释放删除掉，则旧的NG-C1/U1(Master)和旧的Uu-C1/U1(Master)也必须全部被删除释放掉，UE删除掉和旧的Master Node1所有相关联的配置和资源预留协同；如果旧的Master Node1被维护为普通的Secondary node，则旧的NG-C1和旧的Uu-C1可以被删除释放掉，而旧的NG-U1(Master)被重配为普通的NG-U(Secondary)，而旧的Uu-U1(Master)被重配为Uu-U(Secondary)，UE重配且保持和旧的Master Node1所有用户面的相关配置和资源预留协同，但是删除释放掉和旧的Master Node1所有控制面的相关配置和资源预留协同；如果旧的Master Node1被维护为新的Primary Secondary node2，则 旧的NG-C1被重配为NG-C2，而旧的NG-U1(Master)被重配为NG-U2(Primary Secondary)，同时旧的Uu-U1(Master)被重配为Uu-U2(Primary Secondary)，而旧的Uu-C1被重配为Uu-C2，UE重配且保持和旧的Master Node1所有用户面和控制面的相关配置和资源预留协同。
实施例1
如图7系列中所示：在NR/eLTE异构系统中(gNB和eLTE eNB异构混合组网)，有1个gNB基站，2个eLTE eNB基站连接到同一个NGC核心网网元，UE1某时同时处于这三个基站的无线信号覆盖之下，具备做异构多连接数据传输的基本条件。宏基站gNB1的信号覆盖最大，适合做主控锚点基站Master gNB(MgNB1)；微基站eNB2和eNB3覆盖相对较小，适合做分流辅基站Secondary eNB(SeNB2/3)。所有gNB和eLTE基站和UE1都具备本发明的“增强的Master主控+Primary Secondary辅控的异构多连接数据传输模式”能力。
步骤101：主控锚点基站MgNB1通过增强的异构紧耦合多连接数据传输建立流程(具体可参考TS 38.300中紧耦合多连接操作建立流程)，为UE1建立单MgNB1主控下的紧耦合多连接数据传输模式，如图7a所示。在Xn地面接口涉及到XnAP协议下的Secondary Node Addition建立流程(MgNB1和SeNB2/3的双向资源配置的协商确认)，在Uu空口涉及到RRC Connection Reconfiguration流程对UE1进行相关三连接的配置和资源预留协同。三连接操作建立完成后，UE1和作为主控锚点基站的MgNB1有唯一的Uu-C1接口上的RRC控制面连接，核心网NGC和MgNB1有唯一的NG-C1接口上的NGAP控制面连接，上述控制面连接负责UE1的多连接数据传输的控制管理。同时，UE1和作为分流辅基站的SeNB2和SeNB3有各自的Uu-U2/3接口上的用户面连接，为Uu-U1用户面连接进行用户业务数据包的分流传输；NGC和SeNB2和SeNB3也有各自的NG-U2/3接口上的用户面连接(比 如SCG Bearers)，为NG-U1用户面连接进行用户业务数据包的分流传输。在此模式下，UE1和SeNB2和SeNB3都受到唯一的MgNB1主控锚点的控制管理。
步骤102：之后某时刻，主控锚点基站MgNB1通过UE1的RRM测量报告(Measurement Report)和SeNB2的状态资源报告(eNB Status Report)，以及本地的资源状态统计分析，决定为UE1建立MgNB1主控+SeNB2辅控的增强异构多连接数据传输模式，如图7b所示。于是在Xn地面接口涉及到XnAP协议下的Primary Secondary Node Addition建立流程(该流程使得SeNB2升级成为Primary SeNB2，MgNB1需要做附加的配置和资源预留协同，未来让Primary SeNB2独立管理同构同RAT域内的SeNB3)，在Uu空口涉及到RRC Connection Reconfiguration流程对UE1进行相关的配置和资源预留协同。建立完成后，UE1除了和作为主控锚点基站的MgNB1有Uu-C1接口上的RRC控制面连接之外，还和作为辅控锚点基站的Primary SeNB2有Uu-C2接口上的RRC控制面连接(都处于激活的正常工作状态)。核心网NGC除了和MgNB1有NG-C1接口上的NGAP控制面连接之外，还和Primary SeNB2有NG-C2接口上的NGAP控制面连接(也处于激活的正常工作状态)，上述控制面连接负责UE1的增强异构紧耦合多连接数据传输的控制管理。同时，UE1和作为分流辅基站的Primary SeNB2和SeNB3有各自的Uu-U2/3接口用户面连接，为Uu-U1用户面连接进行用户业务数据包的分流传输；NGC和Primary SeNB2和SeNB3也有各自的NG-U2/3接口上的用户面连接(比如SCG Bearers)，为NG-U1用户面连接进行用户业务数据包的分流传输。在此增强模式下，UE1和Primary SeNB2都受到MgNB1主控锚点基站的控制管理，此外UE1和SeNB3还受到Primary SeNB2的辅控锚点的控制管理，MgNB1不再对SeNB3直接控制管理。
步骤103：之后某时刻，主控锚点基站MgNB1通过UE1的主服务小区 集合无线链路失败MCG RLF的上报，得知Uu-U1(MgNB1)用户面链路发生了链路失败(无法继续正常传输UE的专有信令和用户数据)，决定为UE1迅速切换成Primary SgNB1辅控+MeNB2主控的增强异构多连接数据传输模式，如图7c所示。在Xn地面接口涉及到XnAP协议下的Master Node Change建立流程(让Primary SeNB2迅速升级为MeNB2，成为新的主控锚点基站)和Primary Secondary Node Addition建立流程(让MgNB1蜕变为Primary SgNB1，成为新的辅控锚点基站)，在Uu空口涉及到RRC Connection Reconfiguration流程对UE1进行相关配置和资源预留协同。建立完成后，UE1除了和作为新主控锚点基站的MeNB2有Uu-C2接口上的RRC控制面连接之外，还和作为新的辅控锚点基站的Primary SgNB1有Uu-C1接口上的RRC控制面连接(Uu-C1接口上需要进行RRC重建，之后才能处于激活的正常工作状态)。核心网NGC除了和MeNB2有NG-C2接口上的NGAP控制面连接之外，还和Primary SgNB1有NG-C1接口上的NGAP控制面连接(也处于激活的正常工作状态)，上述控制面连接负责UE1的增强异构多连接数据传输的控制管理。同时，UE1和作为分流辅基站的Primary SgNB1和SeNB3有各自的Uu-U1/3接口上的用户面连接，为Uu-U2用户面连接进行用户业务数据包的分流传输；NGC和Primary SgNB1和SeNB3也有各自的NG-U1/3接口上的用户面连接，为NG-U2用户面连接进行用户业务数据包的分流传输(比如SCG Bearers)。在此增强模式下，UE1和Primary SgNB1和SeNB3都受到MeNB2主控锚点基站的控制管理，UE1还受到Primary SgNB1辅控锚点基站的控制管理，Primary SgNB1由于和SeNB3是异构异RAT的，因此不能对其进行管控。
实施例2
如图8系列中所示：在NR/eLTE异构系统中(gNB和eLTE eNB异构混合组网)，有2个gNB基站，1个eLTE eNB基站连接到同一个NGC核 心网网元，UE2某时同时处于这三个基站的无线信号覆盖之下，具备做异构紧耦合多连接数据传输的基本条件。宏基站gNB1的信号覆盖最大，适合做主控锚点基站Master gNB(MgNB1)；微基站eNB2和gNB3覆盖相对较小，适合做分流辅基站SeNB2和SgNB3。所有NR和eLTE基站和UE2都具备本发明的“增强的Master主控+Primary Secondary辅控的异构多连接数据传输模式”能力。
步骤201：主控锚点基站MgNB1通过NR的异构紧耦合多连接数据传输建立流程(具体可参考TS 38.300中NR异构紧耦合多连接操作建立流程)，为UE2建立单MgNB1主控下的异构多连接数据传输模式，如图8a所示。在Xn地面接口涉及到XnAP协议下的Secondary Node Addition建立流程(MgNB1和SeNB2，SgNB3的双向资源配置的协商确认)，在Uu空口涉及到RRC Connection Reconfiguration流程对UE2进行相关三连接的配置和资源预留协同。三连接操作建立完成后，UE2和作为主控锚点基站的MgNB1有唯一的Uu-C1接口上的RRC控制面连接，核心网NGC和MgNB1有唯一的NG-C1接口上的NGAP控制面连接，上述控制面连接负责UE2的异构多连接数据传输的控制管理。同时，UE2和作为分流辅基站的SeNB2和SgNB3有各自的Uu-U2/3接口上的用户面连接，为Uu-U1用户面连接进行用户业务数据包的分流传输；NGC和SeNB2和SgNB3也有各自的NG-U2/3接口上的用户面连接(比如SCG Bearers)，为NG-U1用户面连接进行用户业务数据包的分流传输。在此传统模式下，UE2和SeNB2和SgNB3都受到唯一的MgNB1主控锚点的控制管理。
步骤202：之后某时刻，主控锚点基站MgNB1通过UE2的RRM测量报告(Measurement Report)和SeNB2的状态资源报告(eNB Status Report)，以及本地的资源状态统计分析，决定为UE2建立MgNB1主控+SeNB2辅控的增强异构多连接数据传输模式，如图8b所示。于是在Xn地面接口涉及 到XnAP协议下的Primary Secondary Node Addition建立流程(该流程使得SeNB2升级成为Primary SeNB2，MgNB1需要做附加的配置和资源预留协同)，在Uu空口涉及到RRC Connection Reconfiguration流程对UE2进行相关的配置和资源预留协同。建立完成后，UE2除了和作为主控锚点基站的MgNB1有Uu-C1接口上的RRC控制面连接之外，还和作为辅控锚点基站的Primary SeNB2有Uu-C2接口上的RRC控制面连接(都处于激活的正常工作状态)。核心网NGC除了和MgNB1有NG-C1接口上的NGAP控制面连接之外，还和Primary SeNB2有NG-C2接口上的NGAP控制面连接(处于激活的正常工作状态)，上述控制面连接负责UE2的增强异构多连接数据传输的控制管理。同时，UE2和作为分流辅基站的Primary SeNB2和SgNB3有各自的Uu-U2/3接口用户面连接，为Uu-U1用户面连接进行用户业务数据包的分流传输；NGC和Primary SeNB2和SgNB3也有各自的NG-U2/3接口上的用户面连接(比如SCG Bearers)，为NG-U1用户面连接进行用户业务数据包的分流传输。在此增强模式下，UE2和Primary SeNB2和SgNB3都受到MgNB1主控锚点基站的控制管理，此外UE2还受到Primary SeNB2的辅控锚点的控制管理，Primary SeNB2由于和SgNB3是异构异RAT的，因此不能对其进行管控。
步骤203：之后某时刻，主控锚点基站MgNB1基于UE2的RRM测量上报，预备为UE2做移动切换，比如目标基站为gNB4，在这个切换过程中，Uu-U1(MgNB1)用户面链路必须中断一段时间(无法继续正常传输UE的专有信令和用户数据)，从而决定为UE2迅速切换成临时的仅有Primary SeNB2辅控的增强异构多连接数据传输模式，如图8c所示。在Xn地面接口涉及到XnAP协议下的Master Node Suspend悬挂暂停流程(让Primary SeNB2在没有MgNB1主控的情况下，独立作为辅控锚点控制UE2的多连接操作)和Master Node Handover切换流程(让gNB4成为新的主控 锚点基站Target MgNB4)，在Uu空口涉及到RRC Connection Reconfiguration流程对UE2进行相关配置和资源预留协同。在UE2切换的过程中，UE2和作为辅控锚点基站的Primary SeNB2有Uu-C2接口上的RRC控制面连接；核心网NGC和Primary SeNB2有NG-C2接口上的NGAP控制面连接(处于激活的正常工作状态)，上述控制面连接负责UE2的增强多连接数据传输的控制管理。同时，UE2和作为分流辅基站的Primary SeNB2有Uu-U2接口上的用户面连接，为Uu-U1用户面连接进行用户业务数据包的分流传输；NGC和Primary SeNB2有NG-U2接口上的用户面连接，为NG-U1用户面连接进行用户业务数据包的分流传输(比如SCG Bearers)。此切换过程中SgNB3由于和MgNB1属于同构同RAT域，不受到Primary SeNB2的管控，因此也被悬挂暂停，不能进行用户面数据的分流传输，直到成功切换到MgNB4。在此增强模式下，MgNB1暂时处于切换状态，不能控制管理UE2和Primary SeNB2和SgNB3，直到成功切换到MgNB4成为新的主控锚点基站；UE2临时仅仅受到Primary SeNB2的辅控锚点的控制管理。
实施例3
如图9系列中所示：在NR gNB和eLTE eNB紧耦合系统中(5G框架下的新RAT和eLTE制式的紧耦合联合工作)，有1个NR gNB基站和2个eLTE eNB基站连接到同一个NGC核心网网元，UE3某时同时处于这三个基站的无线信号覆盖之下，具备做NR-eLTE紧耦合异构多连接数据传输的基本条件。宏基站gNB1的信号覆盖最大，适合做主控锚点基站Master gNB(MgNB1)；微基站eNB2和eNB3覆盖相对较小，适合做分流辅基站Secondary eNB(SeNB2/3)。所有NR基站和eLTE基站和UE3都具备本发明的“增强的Master主控+Primary Secondary辅控的异构多连接数据传输模式”能力。
步骤301：主控锚点基站MgNB1通过NR的紧耦合异构多连接数据传 输建立流程(具体可参考TS 38.300中NR紧耦合多连接操作建立流程)，为UE3建立单MgNB1主控下的紧耦合多连接数据传输模式，如图9a所示。在Xn地面接口涉及到XnAP协议下的Secondary Node Addition建立流程(MgNB1和SeNB2/3的双向资源配置的协商确认)，在Uu空口涉及到RRC Connection Reconfiguration流程对UE3进行相关紧耦合三连接的配置和资源预留协同。紧耦合三连接操作建立完成后，UE3和作为主控锚点基站的MgNB1有唯一的Uu-C1接口上的RRC控制面连接，核心网NGC和MgNB1有唯一的NG-C1接口上的NGAP控制面连接，上述控制面连接负责UE3的紧耦合异构多连接数据传输的控制管理。同时，UE3和作为分流辅基站的SeNB2和SeNB3有各自的Uu-U2/3接口上的用户面连接，为Uu-U1用户面连接进行用户业务数据包的分流传输；NGC和SeNB2和SeNB3也有各自的NG-U2/3接口上的用户面连接(比如SCG Bearers)，为NG-U1用户面连接进行用户业务数据包的分流传输。在此传统模式下，UE3和SeNB2和SeNB3都受到唯一的MgNB1主控锚点的控制管理。
步骤302：之后某时刻，主控锚点基站MgNB1通过UE3的RRM测量报告(Measurement Report)和SeNB2的状态资源报告(eNB Status Report)，以及本地的资源状态统计分析，决定为UE3建立MgNB1主控+SeNB2辅控的增强异构多连接数据传输模式，如图9b所示。于是在Xn地面接口涉及到XnAP协议下的Primary Secondary Node Addition建立流程(该流程使得SeNB2升级成为Primary SeNB2，MgNB1需要做附加的配置和资源预留协同，未来让Primary SeNB2独立管理同构同RAT域内的SeNB3)，在Uu空口涉及到RRC Connection Reconfiguration流程对UE3进行相关的配置和资源预留协同。建立完成后，UE3除了和作为主控锚点基站的MgNB1有Uu-C1接口上的RRC控制面连接之外，还和作为辅控锚点基站的Primary SeNB2有Uu-C2接口上的RRC控制面连接(都处于激活的正常工作状态)。 核心网NGC除了和MgNB1有NG-C1接口上的NGAP控制面连接之外，还和Primary SeNB2有NG-C2接口上的NGAP控制面连接(处于激活的正常工作状态)，上述控制面连接负责UE3的增强紧耦合异构多连接数据传输的控制管理。同时，UE3和作为分流辅基站的Primary SeNB2和SeNB3有各自的Uu-U2/3接口用户面连接，为Uu-U1用户面连接进行用户业务数据包的分流传输；NGC和Primary SeNB2和SeNB3也有各自的NG-U2/3接口上的用户面连接(比如SCG Bearers)，为NG-U1用户面连接进行用户业务数据包的分流传输。在此增强模式下，UE3和Primary SeNB2都受到MgNB1主控锚点基站的控制管理，此外UE3和SeNB3还受到Primary SeNB2的辅控锚点的控制管理，MgNB1不再对SeNB3直接控制管理。
步骤303：之后某时刻，主控锚点基站MgNB1和UE3之间发生了MCG RLF，此时Uu-U1(MgNB1)用户面链路必须中断(无法继续正常传输UE的专有信令和用户数据)；MgNB1基于之前UE3的RRM测量上报和Primary SeNB2的状态资源报告(eNB Status Report)，预备为UE3做移动切换，目标基站为Primary SeNB2，从而决定为UE3迅速切换成临时的仅有Primary SeNB2辅控的增强异构多连接数据传输模式，如图9c所示。在Xn地面接口涉及到XnAP协议下的Master Node Suspend悬挂暂停流程(让Primary SeNB2在没有MgNB1主控的情况下，独立作为辅控锚点控制UE3的紧耦合异构多连接操作)和Master Node Handover切换流程(让Primary SeNB2成为新的主控锚点基站Target MeNB2)，在Uu空口涉及到RRC Connection Reconfiguration流程对UE3进行相关配置和资源预留协同。在UE3切换的过程中，UE3和作为辅控锚点基站的Primary SeNB2有Uu-C2接口上的RRC控制面连接；核心网NGC和Primary SeNB2有NG-C2接口上的NGAP控制面连接(处于激活的正常工作状态)，上述控制面连接负责UE3的增强紧耦合异构多连接数据传输的控制管理。同时，UE3和作为分流辅基站的 Primary SeNB2和SeNB3有各自的Uu-U2/3接口上的用户面连接，为Uu-U1用户面连接进行用户业务数据包的分流传输；NGC和Primary SeNB2和SeNB3也有各自的NG-U2/3接口上的用户面连接，为NG-U1用户面连接进行用户业务数据包的分流传输(比如SCG Bearers)。此切换过程中SeNB3由于和Primary SeNB2属于同构同RAT域，因此受到Primary SeNB2的管控，可以继续进行用户面数据的分流传输。在此增强模式下，MgNB1暂时处于切换状态，不能控制管理UE3和Primary SeNB2和SeNB3，直到成功切换到MeNB2成为新的主控锚点基站；UE3和SeNB3临时仅仅受到Primary SeNB2的辅控锚点的控制管理。
步骤304：之后某时刻，源主控锚点基站MgNB1成功完成向目标基站Primary SeNB2的切换，从而Primary SeNB2升级为新的主控锚点基站MeNB2，UE3迅速切换成仅有MeNB2主控的增强异构多连接数据传输模式，如图9d所示。在Xn地面接口涉及到XnAP协议下的Master Node Resume主控恢复流程(让Primary SeNB2升级为新的主控锚点基站MeNB2，独立主控UE3的紧耦合异构多连接操作)，在Uu空口涉及到RRC Connection Reconfiguration流程对UE3进行相关配置和资源预留协同。在UE3切换完成之后，UE3和作为主控锚点基站的MeNB2有Uu-C2接口上的RRC控制面连接；核心网NGC和MeNB2有NG-C2接口上的NGAP控制面连接(处于激活的正常工作状态)，上述控制面连接负责UE3的增强紧耦合多连接数据传输的控制管理。同时，UE3和作为分流辅基站的SeNB3有Uu-U3接口上的用户面连接，为Uu-U2用户面连接进行用户业务数据包的分流传输；NGC和MeNB2和SeNB3也有各自的NG-U2/3接口上的用户面连接，为NG-U2用户面连接进行用户业务数据包的分流传输(比如SCG Bearers)。在此增强模式下，MgNB1及其相关的接口连接资源被释放删除掉；UE3和SeNB3仅仅受到MeNB2的主控锚点的控制管理。

工业实用性
本发明实施例的技术方案，在和主控锚点基站异构异RAT域中，配置增加一个辅控锚点基站，使得原来和单主控锚点基站主控锚点基站做UE异构多连接配置操作相关的控制管理负担被辅控锚点基站部分的分担掉，空间均衡掉主控锚点基站内部控制管理资源和空口信令资源的消耗。辅控锚点基站可以对和自己同构同RAT域中的普通分流辅基站具有独立的控制管理权，而主控锚点基站也只需要对和自己同构同RAT域中的普通分流辅基站进行控制管理，负担相对减轻。
