具体实施方式
为了便于理解，首先介绍本申请实施例中提及的相关术语。
1、MR-DC(Multi-Radio Dual Connectivity，多无线接入技术双连接)
MR-DC是一种泛化的Intra-E-UTRA(Intra-Evolved-UMTS(Universal Moblle Telecommunications System，通用移动通信系统)Terrestrial Radio Access，内部演进的UMTS陆地无线接入)双连接。其中，终端设备可以采用两个不 同的调度提供的无线电资源，上述调度位于两个不同的NG-RAN(5G无线接入网)节点上，通过非理想回程连接。其中一个节点提供NR访问，另一个节点提供E-UTRA或NR访问，且一个节点作为MN(Master Node，主节点)，另一个节点作为SN(Secondary Node，辅节点)。MN和SN通过网络接口连接，且至少有MN连接到核心网络。
2、采用EPC(Evolved Packet Core，演进分组核心网)的MR-DC
E-UTRAN(Evolved-UMTS Terrestrial Radio Access Network，演进的UMTS陆地无线接入网)通过E-UTRA-NR DC(Evolved-UMTS Terrestrial Radio Access-New Radio Dual Connectivity，简称EN-DC，演进的UMTS陆地无线接入-新空口双连接)支持MR-DC。其中，终端设备连接到一个充当MN的eNB(evolved NodeB，演进后的节点B，4G基站)和一个充当SN的en-gNB(en-next generation NodeB，改造后的5G基站)。
3、采用5GC(5G core，5G核心网)的MR-DC
(1)E-UTRA-NR Dual Connectivity NGEN-DC(NG-RAN E-UTRA-NR Dual Connectivity，5G无线接入网演进的UMTS陆地无线接入-新空口双连接)
NG-RAN支持NGEN-DC，其中，终端设备连接到一个充当MN的ng-eNB(next generation evolved NodeB，下一代演进的基站)和一个充当SN的gNB(next generation NodeB，下一代基站)。其中，ng-eNB连接到5GC，gNB通过Xn接口连接到ng-eNB。
(2)NR-E-UTRA Dual Connectivity(简称NE-DC)
NG-RAN支持NE-DC，其中，终端设备连接到一个充当MN的gNB和一个充当SN的ng-eNB。其中，gNB连接到5GC，ng-eNB通过Xn接口连接到gNB。
(3)NR-NR Dual Connectivity(简称NR-DC)
NG-RAN支持NR-DC，其中，终端设备连接到一个充当MN的gNB和一个充当SN的gNB。主gNB通过NG接口连接到5GC，辅gNB通过NG-U接口连接到5GC，且gNB之间通过Xn接口连接。此外，NR-DC也可以用于终端设备接入单个gNB，此时，终端设备接入的gNB可以同时作为MN和SN，同时配置MCG和SCG。
为了更好的理解本申请实施例公开的一种传输控制方法，下面首先对本申请实施例适用的通信系统进行描述。
在5G通信系统中可以采用双连接(Dual Connectivity，DC)架构。在这种架构下，终端设备可以接入两个小区组，如图1所示，分别为主小区组(MasterCell group，MCG)和辅小区组(Secondary Cell group，SCG)其中，MCG和SCG分别对应网络设备侧的MN和SN。MCG中可能包括多个小区(Cell)，上述多个小区中用于发起初始接入的小区称为PCell，顾名思义，PCell为MCG中最“主要”的小区。如图1所示，MCG中除了可以包括PCell之外，还可以包括SCell，其中，PCell和SCell通过载波聚合(Carrier Aggregation，CA)联合在一起。SCG中可以包括主辅小区(PrimarySecondary Cell，PSCell)和SCell。由于很多信令只在PCell和PSCell上发送，为了描述方便，协议中也定义了一个概念：特定小区(special Cell，SpCell)，如图1所示，PCell和PSCell可以统称为SpCell。
也就是说，MCG包括SpCell(PCell)和一个或多个SCell，MCG是指在MR-DC中，与MN相关的一组服务小区。其中，MN是指在MR-DC中，提供到核心网络的控制平面连接的无线接入节点。MN可以是主eNB(在EN-DC中)、主ng-eNB(在NGEN-DC中)或主gNB(在NR-DC和NE-DC中)。SCG包括SpCell(PSCell)和一个或多个SCell，SCG是指在MR-DC中，与SN关联的一组服务小区。其中，SN是指在MR-DC中，无线接入节点，可以没有到核心网络的控制平面连接，为终端设备提供了额外的资源。SN可以是en-gNB(在EN-DC中)、辅ng-eNB(在NE-DC中)或辅gNB(在NR-DC和NGEN-DC中)。
网络侧设备可以为终端设备提供预配置的小区或小区组。例如可以为终端设备提供预配置的至少两个主小区或至少两个主小区组，类似地，网络侧设备也可以为终端设备提供预配置的至少两个辅小区或至少两个辅小区组。终端设备可以基于网络侧设备的指示，激活预配置的小区或小区组，或者去激活预配置的小区或小区组，进而接入激活的小区或小区组对应的接入网设备，从而实现从去激活的源小区或源小区组对应的接入网设备，切换至激活的目标小区或目标小区组对应的接入网设备。
终端设备基于网络侧设备的指示去激活预配置的小区或小区组的过程中，由于去激活的小区或小区组对应的接入网设备并未获知终端设备已对其去激活，或者并未获知终端设备待对其去激活，因此会继续与终端设备之间的传输，导致传输可能会出现失败，占用了不必要的传输资源，造成资源的浪费。
为了解决以上问题，终端设备已去激活的小区或小区组对应的接入网设备可以停止与终端设备之间的传输，或者，终端设备待去激活的小区或小区组对应的接入网设备可以停止与该终端设备之间的传输，从而避免占用了不必要的传输资源，造成资源的浪费。
为了更好的理解本申请实施例公开的一种传输控制方法，下面首先对本申请实施例适用的通信系统进行描述。
请参见图2，图2为本申请实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个接入网设备和一个终端设备，图2所示的设备数量和形态仅用于举例并不构成对本申请实施例的限定，实际应用中可以包括两个或两个以上的接入网设备，两个或两个以上的终端设备。图2所示的通信系统以包括一个第一接入网设备101、一个第二接入网设备102和一个终端设备103为例。
需要说明的是，本申请实施例的技术方案可以应用于各种通信系统。例如：长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、5G新空口(new radio，NR)系统，或者其他未来的新型移动通信系统等。还需要说明的是，本申请实施例中的侧链路还可以称为侧行链路或直通链路。
本申请实施例中的第一接入网设备101和第二接入网设备102是网络侧的一种用于发射或接收信号的实体。例如，接入网设备101可以为演进型基站(evolved NodeB，eNB)、传输接收点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本申请的实施例对接入网设备所采用的具体技术和具体设备形态不做限定。本申请实施例提供的接入网设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU 也可以称为控制单元(control unit)，采用CU-DU的结构可以将接入网设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本申请实施例中的终端设备103是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
可以理解的是，本申请实施例描述的通信系统是为了更加清楚的说明本申请实施例的技术方案，并不构成对于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，随着系统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。

为了说明前述第一指示消息发送的时机，本实施例提供了几种可能的实现方式，本领域技术人员知晓，实际实现方案并不限定于此。
作为第一种可能的实现方式，第二接入网设备向终端设备发送第二指示消息，指示终端设备对第一接入网设备对应的小区或小区组去激活之前，可以向第一接入网设发送第一指示消息，从而停止第一接入网设备与终端设备之间的传输。也就是说，第二接入网设备基于第一指示消息触发发送第二指示消息。
作为第二种可能的实现方式，第二接入网设备向终端设备发送第二指示消息，指示终端设备对第一接入网设备对应的小区或小区组去激活之后，可以向第一接入网设备发送第一指示消息，从而停止第一接入网设备与终端设备之间的传输。也就是说，第二接入网设备基于第二指示消息触发发送第一指示消息：可选地，第二接入网设备接收第一确认反馈消息，其中，所述第一确认反馈消息，表征所述终端设备接收到所述第二指示消息；或者，可选地，第二接入网设备接收第二确认反馈消息，其中，第二确认反馈消息，表征终端设备接入第三接入网设备。
例如在一种可能场景下，执行前述第一种或第二种可能的实现方式，终端设备当前的服务SCG对应的SN发送第二指示消息给终端设备，以使终端设备将当前终端设备的服务MCG从MCG-1变更为MCG-2，该SN也发送第一指示消息给MCG-1对应的MN。SN发送第二指示消息可以在发送第一指示消息之前，也可以是SN发送第二指示消息在发送第一指示消息之后，还可以是，SN同步发送第二指示消息和第一指示消息，本实施例中对此不作限定。
作为第三种可能的实现方式，第二接入网设备接收到第四接入网设备或终端设备发送的通知消息，通知消息是所述第四接入网设备向所述终端设备发送第二指示消息之后发送的，第二接入网设备基于通知消息触发向第一接入网设备发送第一指示消息，从而停止第一接入网设备与终端设备之间的传输。可选地，通知消息用于表征下列中的至少一种：所述第四接入网设备发送所述第二指示消息；所述第四接入网设备接收第一确认反馈消息，所述第一确认反馈消息表征所述终端设备接收到所述第二指示消息；所述第四接入网设备接收第二确认反馈消息，所述第二确认反馈消息表征所述终端设备接入所述第三接入网设备；所述终端设备接入所述第三接入网设备。

第一接入网设备在接收到第一指示消息之前从核心网或者其他接入网设备接收到了该终端设备的下行数据。第一接入网设备在接收到第一指示消息之时，可能还存在未传输给终端设备的下行数据。针对未传输给终端设备的下行数据，作为一种可能的实现方式，第一接入网设备可以丢弃第一接入网设备与终端设备之间未传输的下行数据，从而停止与终端设备之间的传输，以避免终端设备已对第一接入网设备对应的小区或小区组去激活的情况下，第一接入网设备继续向终端设备发送下行数据。
通过实施本申请实施例，第一接入网设备在接收第二接入网设备发送的第一指示消息之后，丢弃第一接入网设备与终端设备之间未传输的下行数据，从而停止与终端设备之间的下行传输，以避免终端设备已对第一接入网设备对应的小区或小区组去激活的情况下，第一接入网设备继续向终端设备发送下行数据，避免占用了不必要的传输资源，造成资源的浪费。
