具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)网络协议架构：如图1所示，网络协议栈包括应用(application，APP)层、业务数据适配协议(service data adaptation protocol，SDAP)、分组数据汇聚层协议(packet data convergence protocol，PDCP)、无线链路控制(radio link control，RLC)层，媒体接入控制(media access control，MAC)层和物理(physical，PHY)层，其中，APP层在SDAP层之上，SDAP层在PDCP层之上，PDCP层位于RLC层之上，RLC层位于MAC之上，MAC层位于PHY层以上。核心网设备的协议栈包括：通用分组无线业务(general packet radio service，GPRS)用户面隧道协议(GPRS tunnelling protocol for the user plane，GTP-U)层、用户数据报协议(user datagram protocol，UDP)层、互联网协议(internet protocol， IP)层、数据链路层(data link layer，DLL)、PHY层，其中，GTP-U层在UDP层之上，UDP层在IP层之上，IP层在data link layer之上，data link layer在physical layer之上。服务器(server)包括APP层。APP层生成的包可以是传输控制协议(transmission control protocol，TCP)/IP包，也可以是以太网(Ethernet)协议里的MAC包，也可以为其他包，在这里并不限制。应理解，上述列举的协议层仅是一种示例，并不对网络协议栈包括的协议层进行具体限定。
2)多播技术：多播是指接入网设备在一份资源发送数据，多个终端设备共同接收的一项技术。接入网设备一般会通过广播或者单播的方式通知终端设备：接入网设备支持的多播业务，通知的内容可以包括一个临时移动组标识(temporary mobile group identity，TMGI)TMGI和一个组无线网络临时标识符(group radio network temporary identifier，G-RNTI)，以及检测G-RNTI的配置信息，例如检测时频位置，检测周期等。应理解，上述通知的内容仅是一种示例，并不对接入网设备通知终端设备的具体内容进行限定。
3)缓冲区状态报告(buffer status report，BSR)技术：目前，无线通信系统中，终端设备与接入网设备之间的数据通信，是依靠接入网设备为终端设备进行资源调度实现的。例如，当终端设备的某个逻辑信道有新数据或者有更高优先级的数据到达的时候，会触发BSR，如果没有直接可用的上行资源，终端设备先发送上行调度请求(scheduling request，SR)向接入网设备请求资源，接入网设备收到SR会为终端设备分配一定大小的资源用于终端设备上报BSR，终端设备在分配的资源上发送BSR来指示自己有多少数据需要发送，以便接入网设备进一步根据BSR决定给终端设备分配多大资源用来传输数据。
BSR组装：当有可用的上行资源的时候，终端设备需要组装BSR，具体的，将终端设备中逻辑信道组中所有待发送数据的数据量(buffer size，BS)信息封装到BSR MAC控制元素(control element，CE)中在上行资源上进行发送。BSR上报可以是基于逻辑信道组进行上报的，体现逻辑信道组中所有逻辑信道一共有多少数据量。示例性的，BSR可以上报一个索引值，该索引值对应一个数据大小的范围，而不是一个精确的上行数据量。
本申请实施例中“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，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的情况，其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a,b,或c中的至少一项(个)，可以表示：a,b,c,a-b,a-c,b-c,或a-b-c，其中a,b,c可以是单个，也可以是多个。
以及，除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的大小、内容、顺序、时序、优先级或者重要程度等。例如，第一信息和第二信息，只是为了区分不同的信息，而并不是表示这两个信息的内容、优先级或者重要程度等的不同。
前文介绍了本申请实施例所涉及到的一些名词概念，下面介绍本申请实施例涉及的技术特征。
NR系统中引入了海量机器连接的应用场景，这种应用将实现大量、快速的数据传输，进而实现对万物实时的遥感、遥测和管理。例如，工业场景、智能监控场景、器件的缺陷检测场景等等，在这些应用场景中对业务的可靠性要求比较高，然而现有的终端设备由于成本的原因，硬件和软件的可靠性不能达到相关业务的要求，如何保证在终端故障时，不 影响业务传输是一个亟待解决的问题。一种可能的解决方案为：如图2所示，物联网设备(例如工业场景中控制各种类型的机械或生产过程的设备(如可编程逻辑控制器(programmable logic control，PLC))、智能监控场景中的监控设备(如摄像头等)、器件的缺陷检测场景中的检测设备等)可以将数据包分别发送到两个终端设备，两个终端设备将相同的数据包发送到接入网和核心网，通过核心网到达数据目的端，也就是物联网的服务器(例如工业场景中用于管理各种类型的机械或生产过程的服务器等)。类似的，下行数据可以通过核心网和接入网分别到达两个终端设备，由两个终端设备发送到物联网设备，物联网设备处理相关数据。通过上述方式，即使一个终端设备发生故障，业务也不会受到影响。但是，上述方式中同一份数据需要从终端设备到接入网到核心网被传输两遍，因此需要消耗双倍空口资源、传输资源、站点的处理资源以及UE的功率资源等。而终端设备的故障是偶发的，为了偶发的事情，长时间消耗大量资源，会降低系统的效率。
另外，在机器连接的应用场景中对数据的传输速率要求较高，例如，工业场景中有大量高清摄像头业务需要回传的控制单元，以便于实时监测工业生产，而高清摄像头的产生高清视频的回传需要非常高的传输带宽，单个终端设备由于功率，硬件能力受限，无法保证大速率的视频业务的回传，因此，如何解决大速率传输也是一个亟待解决的问题。
基于此，本申请实施例提供两种通信方法及装置。本申请实施例中接入网设备可以根据业务的传输模式(或者传输需求或者终端设备的空口质量等)指示多个终端设备的数据传输规则，例如，若业务的传输模式为高可靠传输(或者业务的传输需求为高可靠)，接入网设备可以指示多个终端设备为该业务传输相同的数据包，从而可以保证该业务的可靠性。若业务的传输模式为高速率传输(或者业务的传输需求为高速率)，接入网设备可以指示多个终端设备为该业务传输不同的数据包，从而提高传输速率。通过上述方式，接入网设备可以灵活控制多个终端设备的传输方式，从而根据业务需求(或者终端设备的空口质量)可以实现备份或者分流，进而可以实现业务的高可靠传输和高速率传输。
本申请提供的通信方法可以应用于各类通信系统中，例如，可以是物联网(internet of things，IoT)、窄带物联网(narrow band internet of things，NB-IoT)、长期演进(long term evolution，LTE)，也可以是第五代(5th generation,5G)通信系统，还可以是LTE与5G混合架构，也可以是6G或者未来通信发展中出现的新的通信系统等。通信系统还可以是机器到机器(machine to machine，M2M)网络、机器类通信(machine type communication，MTC)或者其他网络。
示例性的，本申请实施例提供的通信方法可应用于如图3所示的通信系统，该通信系统包括：核心网设备(如核心网设备1和核心网设备2)、接入网设备、交换机/路由器/集线器、终端设备(如UE1～UE3)以及工业设备(如工业设备1～工业设备3)。在该通信系统中，工业设备1和工业设备2通过交换机/路由器/集线器连接到UE1，工业设备3连接到UE2。UE1，UE2，UE3通过无线链路和接入网设备连接，接入网设备与核心网设备1以及核心网设备2相连。应理解，图3仅是通信系统的一种示例性架构，并不对通信系统中包括的通信设备的类型、形态、数量、连接关系等进行具体限定。
本申请实施例也可用于其他通信系统，只要该通信系统中数据发送端需要通过终端设备、接入网设备以及核心网设备将数据传输到数据接收端。
以上所示终端设备，可以为用户侧的一种用于接收或发射信号的实体，也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、 远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置。本申请实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、视频监控中的无线终端以及可穿戴终端设备、客户终端设备(customer-premises equipment，CPE)等。
本申请实施例中，用于实现终端设备的功能的装置可以是终端设备，也可以是能够支持终端设备实现该功能的装置，例如芯片系统，该装置可以被安装在终端设备中。本申请实施例中，芯片系统可以由芯片构成，也可以包括芯片和其他分立器件。本申请实施例提供的技术方案中，以用于实现终端的功能的装置是终端设备为例，描述本申请实施例提供的技术方案。
接入网设备可以是网络侧的一种用于发射或接收信号的实体，例如接入网中在空口通过一个或多个小区与无线终端设备通信的设备。接入网设备可以是NR系统中的下一代基站(next Generation node B，gNB)，可以是LTE系统中的演进型基站(evolutional node B，eNB)等。本申请实施例中，用于实现接入网设备的功能的装置可以是接入网设备，也可以是能够支持接入网设备实现该功能的装置，例如芯片系统，该装置可以被安装在接入网设备中。在本申请实施例提供的技术方案中，以用于实现接入网设备的功能的装置是接入网设备为例，描述本申请实施例提供的技术方案。
核心网设备可以是网络侧用于管理用户、数据传输以及接入网设备配置的多种功能实体的统称，包括访问和移动管理功能(access and mobility management function，AMF)，用户面功能(user plane function，UPF)，会话管理功能(session management function，SMF)等。
工业设备可以是工业场景使用的设备，负责一些控制数据的产生和处理，比如PLC或者摄像头。
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。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。该方法可以应用于数据发送端通过终端设备和接入网设备和核心网设备将数据发送到数据接收端的场景中，例如，工业场景。
参见图4，为本申请提供的一种通信方法的流程示意图。该方法包括：
S401，接入网设备确定第一信息。
其中，第一信息可以用于配置第一业务的数据传输规则，进一步的，第一信息还可以指示第一业务的传输模式。其中，数据传输规则可以理解为分流规则，用于指示多个终端设备如何传输第一业务，具体的数据传输规则、传输模式、第一信息的内容以及接入网设备确定第一信息的方式将在下文详细描述。
示例性的，第一业务的呈现形式可以为但不限于：PDU会话，服务质量流(Qos flow)等。
第一信息可以通过高层信令来承载，高层信令可以为无线资源控制(radio resource control，RRC)消息如RRC重配，或者MAC控制元素(media access control control element， MAC CE)。具体的第一信息也可以在数据无线承载(data radio bearer，DRB)的配置中。
S402，接入网设备向N个终端设备中的至少一个终端设备(下面以其中的第一终端设备为例进行说明)发送第一信息，N个终端设备与第一业务相关，N为大于1的整数。相应的，第一终端设备接收第一信息。应理解，N个终端设备与第一业务相关可以理解为该N个终端设备参与第一业务的传输，其中，在同一时间，该N个终端设备可以都传输第一业务，也可以只有部分终端设备传输第一业务，其他终端设备可以作为备用设备在需要时传输第一业务。或者，N个终端设备与第一业务相关也可以理解为第一设备通过该N个终端设备传输第一业务，第一设备为上行传输中产生第一业务的数据的设备，例如，工业场景中控制各种类型的机械或生产过程的设备(如PLC)、智能监控场景中的监控设备(如摄像头等)、器件的缺陷检测场景中的检测设备等。具体的，第一设备可以通过该N个终端设备中的全部终端设备传输第一业务或者也可以通过该N个终端设备中的部分终端设备传输第一业务。
需要说明的是，该N个终端设备可以在同一个接入网设备下，或者，也可以在不同的接入网设备下，例如，该N个终端设备中至少两个终端设备接入的接入网设备不同。其中，接入同一个接入网设备的多个终端设备可以在同一个小区，也可以在不同的小区，例如，至少两个终端设备所在的小区不同。
可选的，接入网设备可以通过如下方式确定N个终端设备与第一业务相关：第一核心网设备(例如AMF网元)可以向接入网设备发送配置信息，该配置信息可以指示N个终端设备与第一业务相关。
一个实施例中，该配置信息还可以用于配置第一业务在接入网设备与核心网设备之间的传输通道。例如，配置信息还可以包括如下至少一项：接入网与核心网之间传输通道的相关信息，其中，相关信息可以包括如下至少一项：第一业务相关会话ID，服务质量流标识(Qos flow ID，QFI)；隧道(tunnel)地址；业务组标识，用于指示N个终端设备的一个会话(例如第一业务对应的会话)是一个组会话。
配置信息的一种可能的形式为：第一核心网设备向接入网设备发送的配置信息可以包括N个终端设备的配置信息，其中，每个终端设备的配置信息均可以包括第一业务的标识信息。
配置信息的另一种可能的形式为：第一核心网设备向接入网设备发送的配置信息可以包括一个配置信息，其中，该配置信息可以携带上述N个终端设备的标识信息。
S403，第一终端设备根据数据传输规则确定待发送数据包，待发送数据包为第一业务的数据包中第一终端设备需要发送的至少一个数据包。“待发送数据包”可以理解为一个集合。
一种可能的实施方式中，第一终端设备在根据数据传输规则确定待发送数据包之前，可以从应用层或者上层接收第一业务的M个数据包，其中，从应用层或者上层接收到的数据包可以是工业以太协议包，具体的，可以是Ethernet/IP协议包，工业以太网(PROFINET)包，动力联合(POWERLINK)协议包，工业总线协议(EtherCAT)协议包，第三代串行实时通信协议(Sercosserial real time communication specification)接口(SERCOSIII)协议包中的一种，其中，M为大于0的整数。从而，第一终端设备在根据数据传输规则确定待发送数据包时，可以确定上述M个数据包中第一终端设备需要发送的数据包(即待发送数据包)。
可选的，第一终端设备在向接入网设备发送所述待发送数据包之前，可以有根据M个数据包的接收顺序或M个数据包中携带的上层序号为待发送数据包进行编号。
例如，第一终端设备接收到来自应用层或者上层的第一个数据包，将该数据包编号为PDCP SN＝0(也可以是SDAP SN等等)，接收到来自应用层或者上层的第二个数据包，将该数据包编号为PDCP SN＝1，以此类推。
又例如，第一终端设备接收到来自应用层或者上层的上层序号为0的数据包，将该数据包编号为PDCP SN＝0(也可以是SDAP SN等等)，接收到来自应用层或者上层的上层序号为1的数据包，将该数据包编号为PDCP SN＝1，若上层序号为2的数据包丢失，则可以将上层序号为2的数据包对应的PDCP SN号跳过，直接加1，接收到来自应用层或者上层的上层序号为3的数据包，将该数据包编号为PDCP SN＝3。以此类推。
S404，第一终端设备向接入网设备发送待发送数据包。
相应的，接入网设备可以对接收到的数据包进行整理后向第二核心网设备(例如UPF网元)进行发送。以上述至少一个终端设备包括第一终端设备和第二终端设备为例，一种具体的实现方式中，接入网设备在接收到来自第一终端设备的第一业务的数据包和第二终端设备的第一业务的数据包之后，可以将接收到的数据包进行去重和重排序后向第二核心网设备发送。
其中，接入网设备将接收的数据包进行去重，具体可以为：将接收到的数据包中重复的数据包去掉。
接入网设备将接收的数据包进行重排序，具体可以为：根据数据传输规则将接收到的数据包进行排序。举例说明，以UE1和UE2为例，根据数据传输规则，UE1发送第一业务的数据包中序列号为偶数的数据包，UE2发送第一业务的数据包中序列号为奇数的数据包，接入网设备接收到UE1的PDCP序列号(sequence number，SN)为0、2、4、6的数据包，以及UE2的PDCP SN为1、3、5的数据包，接入网设备将来自UE1的数据包和来自UE2的数据包进行重排序，重排序后数据包的顺序为：PDCP SN为0的数据包(来自UE1)、PDCP SN为1的数据包(来自UE2)、PDCP SN为2的数据包(来自UE1)、PDCP SN为3的数据包(来自UE2)、PDCP SN为4的数据包(来自UE1)、PDCP SN为5的数据包(来自UE2)、PDCP SN为6的数据包(来自UE1)，如图5所示。
应理解，这里仅以第一终端设备为例进行说明，而不是N个终端设备只有第一终端设备与接入网设备执行本申请所述的方法，其他终端设备也可以执行本申请实施例中第一终端设备执行的方法与接入网设备进行通信。
本申请实施例中基于接入网侧的控制，使得第一业务的数据可以按照配置的数据传输规则在N个终端设备上进行传输，并且接入网设备可以灵活配置数据传输规则，从而可以配置满足第一业务的高可靠性、高速率等需求的数据传输规则，提高第一业务的传输性能。
第一信息用于配置第一业务的数据传输规则，终端设备根据第一信息确定待传输的数据包，下面介绍第一信息的几种可能的示例。应理解，第一信息也可以为其他指示内容，这里仅是举例说明，并不限定第一信息的具体内容。
示例一，第一信息包括第一终端设备对应的第一值m、门限值中至少一个，第一值、门限值用于确定第一终端设备传输的数据包，其中，第一值m为取余运算中的除数，用于对数据包的序列号进行取余运算。
相应的，第一终端设备可以根据数据包的SN、第一值m和门限值确定是否需要发送 该数据包，也就是该数据包是否包括在待发送数据包中。具体的，第一终端设备可以根据Mod(SN，m)的结果与门限值的比较确定是否该数据包，其中，Mod(SN，m)表示SN除以M得到的余数。进一步的，第一信息还可以指示待发送数据包的Mod(SN，m)的结果与门限值的大小关系，例如，待发送数据包的Mod(SN，m)的结果大于门限值，也就是第一终端设备需要发送满足Mod(SN，m)＞门限值的数据包。
其中，门限值可以包括一个或多个值，具体的，门限值可以与终端设备的数量有关，例如，针对两个终端设备，门限值可以包括1个值，针对三个终端设备，门限值可以包括2个值，针对N个终端设备，门限值可以包括N-1个值。
一种举例说明中，以两个终端设备，即UE1和UE2为例，门限值包括一个值n。接入网设备向UE1发送的第一信息可以包括第一值m和门限值n，并指示发送序列号SN满足Mod(SN，m)的结果＞n的数据包，向UE2发送的第一信息可以包括第一值m和门限值n，并指示发送序列号SN满足Mod(SN，m)的结果≤n的数据包。从而，UE1在接收到对应的第一信息后可以确定发送序列号SN满足Mod(SN，m)＞n的数据包。UE2在接收到对应的第一信息后可以确定发送序列号SN满足Mod(SN，m)≤n的数据包。
另一种举例说明中，以三个终端设备，即UE1、UE2和UE3为例，门限值包括2个值n，即n1和n2，其中，n1＞n2。接入网设备向UE1发送的第一信息可以包括第一值m以及门限值n1，并指示发送序列号SN满足Mod(SN，m)的结果＞n1的数据包；向UE2发送的第一信息可以包括第一值m和门限值n1和n2，并指示发送序列号SN满足n2≤Mod(SN，m)的结果≤n1的数据包；向UE3发送的第一信息可以包括第一值m和门限值n2，并指示发送序列号SN满足Mod(SN，m)的结果＜n2的数据包。从而，UE1在接收到对应的第一信息后可以确定发送序列号SN满足Mod(SN，m)＞n1的数据包。UE2在接收到对应的第一信息后可以确定发送序列号SN满足n2≤Mod(SN，m)≤n1的数据包。UE3在接收到对应的第一信息后可以确定发送序列号SN满足Mod(SN，m)＜n2的数据包。
基于该示例一，接入网设备可以通过第一值为m＝1，门限值为0且指示发送的数据包满足：Mod(SN，m)与门限值的大小关系为相等的方式，指示终端设备发送第一业务的全部数据。进一步的，接入网设备向多个终端设备发送上述内容的第一信息，可以指示该多个终端设备均发送第一业务的全部数据，从而可以实现第一业务的备份传输。
接入网设备可以通过第一值为m＝1，门限值为0且Mod(SN，m)与指示发送的数据包满足：门限值的大小关系为不相等的方式，指示终端设备不发送第一业务的数据。
在上述示例一中，第一值m(或者门限值n)可以是预先设置的，或者，通过其他信令(如高层信令)预先配置的，或者，也可以协议规定的。
需要说明的是，本申请实施例所述SN号可以为PDCP SN号或RLC SN号或者SDAP序号或者上层SN号或者其他序列号。
示例二，第一信息可以指示第一终端设备不发送第一业务的数据包，或者，发送第一业务的数据包。
进一步的，若第一信息指示第一终端设备发送第一业务的数据包，接入网设备还可以向第一终端设备发送PDCP状态报告或者第一序列号，其中，PDCP状态报告指示成功接收的数据包和/或未成功接收的数据包，第一序列号为第一终端设备需要发送的第一个数据包的序列号或者为第一终端设备需要发送的数据包对应的序列号。从而，第一终端设备可以根据PDCP状态报告或者第一序列号确定待发送数据包。
可选的，第一信息可以承载在RRC消息或者MAC CE或者下行控制信息(downlink control information，DCI)中。
示例三，第一信息可以指示第一终端设备发送序列号为奇数或者偶数的数据包。
示例四，第一信息可以指示第一终端设备的分流比例，分流比例用于指示在k个数据包(可以视为一个数据包分组)中第一终端设备需要发送的数据包的数量与k的比例。其中，k可以为设置的数据包的数量，也可以为一段时间或者一个传输窗内包括的数据包的数量。
一种实现方式中，该分流比例可以为在k个数据包中第一终端设备需要发送的数据包的数量与k的比例大小。例如，第一信息指示第一终端设备发送k个数据包的1/2、1/3、3/7或者10％、23％、40％等等。进一步的，第一信息还可以包括如下至少一项：数据包的位置、k的取值，其中，数据包的位置用于指示第一终端设备需要发送的数据包在k个数据包中的位置。如果分流比例和k值在计算后不是整数，可以进行取整。
举例说明，接入网设备向UE1发送的第一信息可以包括：k＝10(即以10个数据包为单位进行划分)、分流比例(30％)、数据包的位置为10个数据包的前面(即每10个数据包的前3个数据包)。接入网设备向UE2发送的第一信息可以包括：k＝10(即以10个数据包为单位进行划分)、分流比例(70％)、数据包的位置为10个数据包的后面(即每10个数据包的后7个数据包)。
需要说明的是，数据包的位置可以预先设置的，也可以是接入网设备通过其他信令(如高层信令)预先配置的，也可以是协议规定的。
另一种实现方式中，分流比例可以为在k个数据包中第一终端设备需要发送的数据包相对于该k个数据包的区间。例如，第一信息指示前30％的数据包、(30％，60％)的数据包、(60％，100％)的数据包等等，应注意，该比例划分仅是举例说明。进一步的，第一信息还可以指示k的取值。如果分流比例和k值在计算后不是整数，可以进行取整。例如可以向上取整或者向下取整，或者根据余数大小取整，比如round函数，round函数用于按指定的位数对数值进行四舍五入。
举例说明，接入网设备向UE1发送的第一信息可以包括：k＝10(即以10个数据包为单位进行划分)、分流比例(前30％)。接入网设备向UE2发送的第一信息可以包括：k＝10(即以10个数据包为单位进行划分)、分流比例(30％～70％)。接入网设备向UE3发送的第一信息可以包括：k＝10(即以10个数据包为单位进行划分)、分流比例(70％～100％)。相应的，UE1可以发送每10个数据包的前3个数据包，UE2可以发送每10个数据包的第4～7个数据包，UE3可以发送每10个数据包的最后3个数据包。
需要说明的是，k的取值可以预先设置的，也可以是接入网设备通过其他信令(如高层信令)预先配置的，也可以是协议规定的。分流比例可以是针对每个数据包分组的，也可以是针对每个数据包分组分别指示分流比例。在具体实施方式中，分流比例可以进行更新。
可选的，接入网设备可以动态修改数据传输规则，例如，接入网设备在发送第一信息之后，还可以更新数据传输规则。具体的，接入网设备可以通过MAC CE，或者RRC消息等动态修改数据传输规则。
示例五，第一信息也可以指示第一终端设备需要发送的数据包的序列号的范围。
具体的上述数据传输规则可以只对至少一个终端设备(例如第一终端设备、第二终端 设备或者N个终端设备中的其他终端设备等)进行发送，该至少一个终端设备可以基于数据传输规则确定要发送的数据包后，可以通过终端设备之间的接口，将其余数据包发送给其他终端设备，其中，传输到其他终端设备的数据包可以PDCP数据包、RLC数据、MAC数据包、SDAP数据包等。终端设备之间的接口可以是有线的也可以是无线的。具体的，终端设备可以在接入网设备的指示下，确定不同终端设备发送哪些数据包，并通过终端设备之间接口将该数据包传输给其他终端设备。在这种场景下不要求应用层架构与多个终端相连接，与至少一个终端连接即可。由连接应用层的终端设备将数据分流至其他终端设备。
通过上述方式使得多个终端设备可以共同完成上行传输任务。实现高可靠传输或者大上行速率。
可选的，本申请实施例中，数据传输规则可以根据第一业务的传输模式或者第一业务的业务需求或者根据空口质量确定。下面对第一业务的传输模式进行示例性说明。
第一业务的传输模式可以为第一模式，在第一模式中，N个终端设备中只需要部分终端设备传输第一业务。进一步的，N个终端设备可以分为两类，一类为主终端设备，另一类为备份终端设备，也就是，N个终端设备可以包括至少一个主终端设备和至少一个备份终端设备。其中，主终端设备可以优先传输第一业务，备份终端设备可以用于在主终端设备故障时再传输第一业务。该模式也可以称为备份模式。其中，备份终端设备传输第一业务的启动条件可以是主终端设备全部故障，也可以是存在主终端设备故障(发生故障的主终端设备的数量不限)。可选的，备份终端设备可以在接入网设备的指示下开始传输第一业务。
以N等于2为例，N个终端设备包括一个主终端设备和一个备份终端设备，该备份终端设备用于在该主终端设备故障时传输第一业务。
在上述第一模式中，当传输第一业务的主终端设备故障时可以通过备份终端设备继续传输第一业务，从而可以保证第一业务的可靠性，并且，在第一模式中，备份终端设备在主终端设备故障时开始传输第一业务，相比于图2所示的备份方式，可以节省资源，提高系统的效率。
或者，第一业务的传输模式也可以为第二模式，在第二模式中，N个终端设备均传输第一业务，且N个终端设备传输的数据包相同。该模式也可以称为高可靠模式。
在上述第二模式中，通过多个终端设备传输第一业务相同的数据，可以保证第一业务的可靠性。
或者，第一业务的传输模式还可以为第三模式，在第三模式中，N个终端设备均传输第一业务，且N个终端设备传输的数据包不同。该模式也可以称为高速率模式。
在上述第三模式中，通过多个终端设备传输第一业务不同的数据，可以保证第一业务的传输速率。
或者，第一业务的传输模式还可以为第四模式，在第四模式中，N个终端设备均传输第一业务，且第一终端设备传输的数据包与N个终端设备中的第二终端设备传输的数据包相比存在相同的数据包和不同的数据包。该模式也可以称为混合模式。比如数据传输规则针对不同的终端设备指示的需要发送的数据包可以有重复的地方，比如根据数据传输规则，一个终端设备发送前50％的数据包，另一个终端设备发送后60％的数据包，则这两个终端设备有10％的数据包的重合。
一种可能的实施方式中，第一业务的传输模式可以是接入网设备确定的。例如，接入 网设备可以根据如下至少一项确定第一业务的传输模式：与N个终端设备中至少一个终端设备之间的信道质量(也就是终端设备和接入网设备之间的空口质量)、N个终端设备中至少一个终端设备的工作状态(例如是否故障、是否正常工作、负载情况等)、第一业务的服务质量(quality of service，Qos)需求。
举例说明，接入网设备可以根据终端设备的空口质量确定为第一模式，具体的，当某个终端设备的空口质量比较好时，则可以只需要该终端设备传输第一业务，若检测到该终端设备工作状态出现问题(例如故障、负载太大等)，则接入网设备可以指示另一个终端接管上述终端设备的第一业务。
再比如，接入网设备可以根据终端设备的空口质量、工作状态、第一业务的Qos需求等情况确定为第三模式，进一步的，可以根据终端设备的空口质量、负载等确定第一业务的分流比例。例如，一个终端设备的空口质量好，另一个终端设备的空口质量差，则接入网设备可以指示空口质量好的终端设备发送更多的数据包，另外一个终端设备发送较少的数据包。负载情况也类似，接入网设备可以指示负载小的终端设备发送的数据包可以比负载大的终端设备发送的数据包多。
其中，接入网设备确定与终端设备之间的信道质量的方式可以为：通过该终端设备上报的信道质量信息(channel quality information，CQI)确定、通过该终端设备上报的测量报告确定、接入网设备通过上行测量确定等。
接入网设备确定终端设备的工作状态的方式可以为：其他终端设备向接入网设备上报上述终端设备正常工作或出现故障、上述终端设备上报自己的负载情况和/或干扰情况。一种具体的实施方式中，UE1和UE2在工作时，若UE1判断UE2发送故障，UE1向接入网设备发送指示信息，比如MAC CE或者RRC消息，用于指示UE2故障。其中，UE1可以通过终端设备之间的心跳包或者终端设备之间的其他接口判断UE2处于故障状态或者非正常工作状态。
接入网设备确定终端设备的工作状态的方式还可以为：接入网设备可以根据终端设备上行的数据传输情况以及应答消息(acknowledgement，ACK)反馈情况或者参考信号来判断终端设备的链路或者设备出现故障。
另一种可能的实施方式中，第一业务的传输模式也可以是第一核心网设备指示的。例如，第一核心网设备向接入网设备发送第一指示信息，第一指示信息指示第一业务对应的传输模式。示例性的，第一指示信息可以是显示的指示信息，也可以是根据QoS信息或者会话相关信息隐式确定的。
另一种可能的实施方式中，接入网设备确定第一业务的传输模式后，可以向终端设备发送指示信息，指示信息用于第一业务模式的切换，比如从第一模式切换至第二模式。
可选的，除了通过上述第一信息配置数据传输规则以外，接入网设备还可以配置上述至少一个终端设备的DRB，例如，可以向上述至少一个终端设备发送第二信息，第二信息用于配置第一业务的DRB。示例性的，第二信息可以承载在RRC连接重配置消息中。相应的，上述至少一个终端设备可以基于第二信息配置第一业务的数据无线承载。
示例性的，第二信息配置的DRB可以为专用DRB，该专用DRB可以用于某一种或某几种传输模式的数据传输。具体的，可以在第二信息配置DRB的字段中包含模式传输指示信息，该模式指示信息用于指示该DRB对应的传输模式，或者，模式指示信息用于指示被激活(或者使能)的传输模式。具体的，接入网设备可以通过两种方式中任一种方式 指示该DRB对应的传输方式：
方式一：接入网设备可以发送RRC连接重配置消息，该RRC连接重配置消息的DRB配置(即第二信息)中可以包含DRB ID、模式指示信息等信息，其中，DRB ID用于标识对应的DRB。
方式二：接入网设备可以发送RRC连接重配置消息，该RRC连接重配置消息包括DRB配置(即第二信息)以及DRB对应的PDCP配置或者RLC配置或者MAC配置，其中，DRB对应的PDCP配置或者RLC配置或者MAC配置可以指示该DRB对应的传输模式，或者，指示被激活(或者使能)的传输模式。
需要说明的是，该第一业务的数据传输规则(即第一信息)与DRB配置(即第二信息)可以通过不同消息指示，也可以是通过同一个消息指示给终端设备。进一步的，若第一信息和第二信息通过同一个消息指示给终端设备，如RRC连接重配置消息的DRB配置(即第二信息)中包括第一信息，则也可以通过第一信息指示DRB对应的传输模式，也就是第一信息可以作为上述模式指示信息来指示DRB对应的传输模式。
为了便于理解本申请实施例提供的方案，下面以第一核心网设备为AMF网元，第二核心网设备为UPF网元为例，结合图6所示场景对第一业务的数据传输过程进行示例性描述。图6所示场景中，PLC1连接到UE1，UE1负责发送和接收PLC1相关的业务数据；PLC3连接到UE1和UE2，PLC3的上行业务数据通过自己或者通过其他设备发送到UE1和UE2，下行业务通过UE1和/或UE2发送到PLC3。PLC2连接到UE2，UE2负责发送和接收PLC2相关的业务数据。以PLC3的第一业务为例进行说明。
参考图7的示例性说明，第一业务的数据传输过程可以包括：
S701，AMF网元向接入网设备发送第一业务的配置信息。
其中，第一业务的配置信息用于配置第一业务在接入网与核心网之间的传输通道。具体的，第一业务的配置信息可以包括如下至少一项：UE1和UE2与第一业务相关；接入网与核心网之间传输通道的相关信息，其中，相关信息可以包括如下至少一项：第一业务相关会话ID，QFI；tunnel地址；业务组标识，用于指示UE1和UE2的某个会话是一个组会话。
一种具体的实现方式中，AMF向接入网设备发送的UE1的配置信息和UE2的配置信息，且每个终端设备的配置信息均可以包括第一业务的标识信息。
另一种具体的实现方式中，AMF向接入网设备发送一个配置信息，其中，该配置信息可以携带UE1的标识信息和UE2的标识信息。
需要说明的是，步骤S701可以是一个可选的步骤。
S702，接入网设备对UE1和UE2进行配置。
具体的，接入网设备可以根据UE1和UE2与第一业务的绑定关系(或者关联关系或者相关关系)以及第一业务的传输模式对UE1和UE2进行配置，其中，第一业务的传输模式可以参阅上文的相关描述。
第一业务的传输模式可以AMF网元通过第一业务的配置信息指示给接入网设备的，也可以是接入网设备自己确定的，具体确定方法参阅前文，这里不再重复赘述。
一种实施方式中，接入网设备可以对UE1和UE2的DRB进行配置。例如，接入网设备可以向UE1和UE2配置专用DRB，所述DRB可以用于一种或多种传输模式的数据传输。
可选的，接入网设备对UE1和UE2进行配置时，向UE1和UE2发送RRC连接重配置消息。其中，RRC连接重配置消息的DRB配置中可以包含对DRB ID，模式指示信息等至少一个信息，其中DRB ID用于标识对应的DRB，模式指示信息用于指示该DRB对应的传输模式，或者，指示该DRB被激活(或者使能)的传输模式。或者，RRC连接重配置消息的DRB对应的PDCP配置，或者RLC配置，或者MAC配置也可以指示该DRB对应的传输模式，或者，指示该DRB被激活(或者使能)的传输模式。
接入网设备对UE1和UE2进行配置时，还可以对UE1和UE2的数据传输规则进行配置。数据传输规则可以参阅前文描述，这里不再赘述。
S703，UE1和UE2基于数据传输规则传输第一业务的数据。
具体的，UE1(或UE2)可以根据数据传输规则确定第一业务的数据包中需要自己发送的数据包并发送给接入网设备，其中，第一业务的数据包来自应用层或上层。以上述示例三所述数据传输规则为例，UE1可以发送第一业务的数据包中序列号为奇数的数据包，UE2可以发送第一业务的数据包中序列号为偶数的数据包。
S704，接入网设备将来自UE1和UE2的数据包进行去重和重排序。
其中，接入网设备进行去重和重排序的过程可以参阅前文所述，这里不再赘述。
S705，接入网设备将去重和重排序后的数据包发送给UPF。
下面结合终端设备的协议栈对UE1和UE2传输第一业务的过程进行示例性描述。在下面的示例性描述中，QoS flow 1代表PLC1的业务；QoS flow 2代表PLC2的业务，QoS flow 3代表PLC3的业务(如第一业务)。
第一种示例，UE1和UE2可以基于如图8所示的协议栈进行数据传输。在图8所示协议架构中，UE侧PDCP层具有根据上层数据包的上层序号来生成PDCP包的编号的能力。接入网侧PDCP层具有处理两套安全参数(即UE1的安全参数和UE2的安全参数)的能力，进而具有处理来自两个UE的PDCP包的能力，其中，接入网设备通过一个PDCP层实体处理来自两个UE的PDCP包。
以上行传输为例进行说明。
UE1和UE2基于图8所示的协议栈进行上行传输过程包括：UE1和UE2的应用层实体接收第一业务的数据包，需要说明的是，UE1和UE2接收到的是相同的数据包。UE1和UE2基于第一业务的数据包的接收顺序或第一业务的数据包中携带的序号进行编号。
具体的，UE1的PDCP层实体根据QoS flow 3传输的数据包的顺序或者数据包中的序列号为数据包进行PDCP层编号，示例性的，QoS flow 3传输的数据包为工业以太协议包，具体的，可以是Ethernet/IP，PROFINET，POWERLINK，EtherCAT，SERCOSIII中的一种。其中，当上层(如应用层实体)出现丢包时，PDCP层实体进行编号时可以相应的进行跳号，例如，QoS flow 3传输的数据包2号丢失，则PDCP层实体可以将2号数据包对应的PDCP SN号跳过，直接加1。类似的，UE2的PDCP层实体也可以采用上述方式进行PDCP层编号。
在进行PDCP层编号之后，UE1和UE2可以基于数据传输规则传输第一业务。例如，UE1和UE2接收到上述示例一的数据传输规则，且第一值m＝3，门限值n＝0，UE1发送PDCP SN Mod 3＝0(即Mod(SN，3)＝0)的数据包，UE2发送PDCP SN Mod 3不为0(即Mod(SN，3)≠0)的数据包。
其中，UE1(或UE2)对于不需要发送的数据包可以进行缓存，缓存时间可以是接入 网设备向UE指示的，也可以默认时长，也可以是预先设置的。可选的，若缓存时间超时则可以丢弃相应的数据包。或者，UE1(或UE2)对于不需要发送的数据包也可以进行丢弃。
或者，UE1(或UE2)也可以只缓存需要发送的数据包，不需要发送的数据包可以丢弃。具体的，缓存的数据包可以基于底层传输指示丢弃，也可以基于定时器丢弃。
或者，接入网设备也可以指示UE1(或UE2)是否需要缓存不需要发送的数据包。例如，接入网设备可以指示UE1和UE2缓存不需要发送的数据包，从而当其中一个终端设备(例如UE1)出现故障，接入网设备可以指示另一个终端设备(例如UE2)传输第一业务的所有数据包。进一步的，当UE1故障时，接入网设备可以向UE2发送指示信息，指示信息中包含PDCP SN序号，用于指示UE2从该SN号开始，传输所有的数据包。
此外，本申请实施例也可以基于上述架构，不做PDCP的增强(即终端设备侧不支持根据上层数据包的上层序号进行PDCP层编号，仅根据数据包到达顺序进行编号)。默认每个UE PDCP层的SN号编排都是可靠的，多个UE对统一业务数据包编排是一致的。
相应的，接入网设备基于图8所示的协议栈进行上行处理的过程包括：接入网设备为UE1和UE2建立一个PDCP层实体，该PDCP层实体用于将UE1和UE2发送的数据包根据包携带的编号(SN)，进行PDCP层数据包的去重和重排序，并将数据包按序递交到一个UE1和UE2为QoS flow 3建立的公共tunnel上，传输到UPF。其中，接入网设备进行去重和重排序的过程可以参阅前文的相关描述，这里不再重复赘述。
以下行传输为例进行说明。
接入网设备基于图8所示的协议栈进行下行传输过程包括：接入网设备的PDCP层实体(即接入网设备为UE1和UE2建立的PDCP层实体)对来自UPF的对应QoS flow 3的数据包进行编号，并将数据包传输到RLC层实体1，或者，传输到RLC层实体2，或者传输到RLC层实体1和RLC层实体2，其中，RLC层实体1为接入网设备中对应UE1的Qos flow3的RLC层实体，RLC层实体2为接入网设备中对应UE2的Qos flow3的RLC层实体。其中，下行传输中接入网设备的PDCP层可以支持两个终端设备使用相同的安全参数，也可以支持两个终端设备使用不同的安全参数。
具体的，RLC层实体1和RLC层实体2的数据包分配情况，可以是接入网设备基于UE1和UE2的信道质量(也可以参考其他因素，例如数据传输规则、UE状态等)确定的，也可以是AMF(或者UPF或者其他核心网设备)指示的。
进一步的，若接入网设备向UE1和UE2分别发送一部分数据包，接入网设备在进行PDCP层编号时可以针对不同UE独立编号。通过上述方式，使得UE1和UE2可以使用现有机制接收数据包并递交到应用层，如PLC3。或者，接入网设备在进行PDCP层编号时也可以将数据包统一进行编号，在该方式中，UE1和UE2需要具有支持PDCP层数据包乱序递交的能力。
一种具体的实施方式中，接入网设备进行下行传输时可以采用组播的方式，也就是对UE1和UE2使用相同的G-RNTI加扰，采用相同的安全加密数据进行加密，并统一进行数据编号。通过上述方式，接入网设备可以只发一份数据，而UE1和UE2可以在相同的资源上接收数据，并递交给应用层，从而可以节省传输资源。
上述示例中，通过增强PDCP层，使得终端设备侧的PDCP层支持根据上层数据包的上层序号为数据包编排序号，从而可以实现应用层到接入层数据的统一数据编排序号。接 入网设备侧的PDCP层支持重排序和去重功能，可以使得接入网设备到核心网设备之间只发送一份数据，而没有重复和乱序等情况。
第二种示例，UE1和UE2可以基于如图9所示的协议栈进行数据传输。在图9所示协议架构中，可以在UE侧和接入网设备侧各增加一个适配层，该适配层可以位于终端设备中，例如，在SDAP层之上，或者，终端设备侧的适配层也可以是位于终端设备和工业设备(或者第一业务的数据发送端)之间的中间件，比如交换机、路由器、集线器等。接入网设备侧的适配层可以位于接入网设备中，例如，在SDAP层之上，或者，也可以是位于终端设备和接入网设备之间的中间件。
UE侧适配层具有根据上层数据包的上层序号进行编号的能力。接入网侧适配层可以处理来自两个UE的适配层包的能力，其中，接入网设备通过一个适配层实体处理来自两个UE的适配层包。
第二种示例中，UE1和UE2与接入网设备进行上下行传输的过程与第一种示例中UE1和UE2与接入网设备进行上下行传输的过程类似，区别在于，第一种示例中通过PDCP层实体实现根据上层数据包的序号来进行编号等功能，而在第二种示例中通过适配层实体根据上层数据包的序号来进行编号等功能，重复之处不再赘述。
上述示例中，通过在应用层和接入层之间引入新的一层叫适配层，使得终端设备侧可以支持根据上层数据包的上层序号为数据包编排序号，从而可以实现应用层到接入层数据的统一数据编排序号。接入网设备侧可以支持重排序和去重功能，可以使得接入网设备到核心网设备之间只发送一份数据，而没有重复和乱序等情况。
第三种示例，UE1和UE2可以基于如图10所示的协议栈进行数据传输。在图10所示协议架构中，UE侧SDAP层具有根据上层数据包的上层序号进行编号的能力。接入网侧SDAP层可以处理来自两个UE的SDAP包的能力，其中，接入网设备通过一个SDAP层实体处理来自两个UE的SDAP包。
第三种示例中，UE1和UE2与接入网设备进行上下行传输的过程与第一种示例中UE1和UE2与接入网设备进行上下行传输的过程类似，区别在于，第一种示例中通过PDCP层实体实现根据上层数据包的序号来进行编号等功能，而在第二种示例中通过SDAP层实体根据上层数据包的序号来进行编号等功能，重复之处不再赘述。
上述实现方式中，通过增强SDAP层，使得终端设备侧的SDAP层支持根据上层数据包的上层序号为数据包编排序号，从而可以实现应用层到接入层数据的统一数据编排序号。接入网设备侧的SDAP层支持重排序和去重功能，可以使得接入网设备到核心网设备之间只发送一份数据，而没有重复和乱序等情况。
以上结合图6所示场景介绍了第一业务的数据传输过程。而在第一业务的数据传输中，难免会出现丢包的情况。例如，在上行传输过程中，终端设备未成功向接入网设备发送某个数据包。例如，如图11所示，UE1需要传输序列号为1/3/5的数据包，UE2需要传输序列号为2/4/6的数据包，但是UE1未将序列号为3的数据包传输到接入网设备，导致序列号为3的数据包丢包。下面以UE1丢包为例，介绍处理上行传输过程中丢包的方法以及处理下行传输过程中丢包的方法。
针对上行传输过程中丢包的情况，一种可能的实施方式中，接入网设备确定UE1发送第一数据包失败，可以指示UE2发送该第一数据包，其中，第一数据包为UE1根据数据传输规则确定的需要发送的数据包(例如图11中的序列号为3的数据包)。
一种实现方式中，接入网设备指示UE2发送该第一数据包的方式为：向UE2发送第一数据包的序列号，以指示UE发送该第一数据包。UE2在接收到该序列号后，向接入网设备发送该序列号对应的数据包。所述第一数据包的序列号可以包含在PDCP包(如PDCP控制PDU)中。可选的，接入网设备还可以发送DRB的标识。UE可以发送该DRB的该序列号对应的数据包。
另一种实现方式中，接入网设备指示UE2发送该第一数据包的方式为：向UE2发送PDCP状态报告，该PDCP状态报告指示成功接收的数据包的序列号和/或未成功接收的数据包的序列号。UE2在接收到该PDCP状态报告后向接入网设备发送该接入网设备未成功接收的数据包。
可选的，接入网设备可以通过如下方式确定UE1发送第一数据包失败：接收到来自UE1的第二指示信息，第二指示信息指示第一数据包丢包。具体的，第二指示信息可以指示UE1未接收到或者未成功发送第一数据包。其中，“未成功发送”也可以理解为UE1未从应用层接收到第一数据包，导致不能向接入网设备发送第一数据包。可选的，UE1可以根据从应用层接收到的数据包的情况(例如根据数据包的序列号)确定第一数据包丢包。
或者，接入网设备也可以通过如下方式确定UE1发送第一数据包失败：接入网设备根据数据包的接收情况(例如根据数据包的序列号)确定第一数据包丢包，比如接收到序列号为1和3的数据包，未接收到序列号为2的数据包，则可以确定序列号为2的数据包丢失。
通过上述实施方式，当UE1需要发送的数据包出现丢包时，UE2可以在发送自己需要发送的数据包之外还可发送UE1丢包的数据包，从而可以提高业务的可靠性。
应理解，本申请实施例仅以UE1和UE2分流传输为例进行说明，并不限定为UE2传输UE1的第一数据包，如果有其他UE与第一业务相关，也可以通过其他UE传输第一数据包，该其他UE根据数据传输规则可以传输第一业务的全部数据或者部分数据，也可以在当前时间节点没有传输第一业务的数据，这里不做具体限定。
此外，接入网设备指示终端设备发送不是自己的待发送数据包的实施方案并不限于丢包的场景中，在其他场景中也可以实施上述方案。
针对下行传输过程中丢包的情况，UE1确定下行数据包未正常收到，可以向接入网设备指示该数据包序列号。接入网设备可以将该序列号对应的数据包向UE2发送，也可以同时向UE1发送。
以上介绍的数据传输过程基于接入网设备通过第一信息指示的数据传输规则进行的，而在传输第一业务的过程中，数据传输规则可以改变，例如，在UE1和UE2与接入网设备进行数据传输过程中，接入网设备也可以更新数据传输规则。应理解，在更新数据传输规则，数据传输过程与更新前的数据传输过程类似，区别在于采用的数据传输规则不同，重复之处不再赘述。
具体的，在更新数据传输规则时可以只更新部分参数，另一部分参数可以维持不变。接入网设备也可以在两个UE之间进行业务切换，例如，将第一业务的数据包中需要UE的发送的数据包切换到UE2，由UE2发送UE1需要发送的数据包。接入网设备还可以指示两个UE中的一个UE接管另一个UE的业务，例如，可以指示UE2接管UE1的第一业务，也就是，UE2除了发送需要自己发送的数据包之后，还发送需要UE1发送的数据包，UE1可以停止发送第一业务的数据包。
进一步的，在上述三种场景中(即接入网设备更新数据传输规则、将UE1的第一业务切换到UE2、指示UE2接管UE1的第一业务)，接入网设备可以指示UE1上报PDCP数据状态报告，该PDCP数据状态报告可以指示UE1未成功接收的下行数据包或已经成功接收的下行数据包，接入网设备可以从UE1未正常接收的数据包开始向UE2发送下行数据包。
在第一业务的数据传输中，终端设备与接入网设备之间的数据通信，是基于接入网设备为终端设备进行资源调度实现的。以上行传输为例，终端设备基于BSR上报机制触发接入网设备为该终端设备分配上行资源。目前，终端设备的BSR上报机制为：当终端设备的某个逻辑信道有新数据或者有更高优先级的数据到达的时候，会触发BSR上报，且上报的BSR体现终端设备一共有多少数据量。而基于申请实施例提供的数据传输方法，接入网设备基于终端设备上报的BSR分配的上行资源可能与终端设备需要上报的数据量不匹配，例如，终端设备在接收到第一业务的数据包后将其中的一部分数据包向接入网设备发送(例如根据上述示例3所述的数据传输规则发送数据包)，而接入网设备基于BSR上报的数据量为终端设备分配上行资源可能会导致资源浪费。基于此，本申请实施例还提供三种BSR上报方法。应理解，本申请实施例提供的BSR上报方法也可以不依赖于上述数据传输过程，单独实施。
下面以h个终端设备为例介绍三种BSR上报方法，其中，h为大于0的整数，h个终端设备为上述N个终端设备中全部终端设备或部分终端设备。
方法一，h个终端设备将接收到的第一业务的数据包全部进行缓存，h个终端设备中的全部终端设备或部分终端设备触发并上报BSR，该BSR指示终端设备缓存的数据量。接入网设备根据接收到的BSR以及数据传输规则为该h个终端设备分配上行资源，具体的，接入网设备可以根据数据传输规则和BSR确定h个终端设备各自需要发送的数据包的数量，并针对每个终端设备，根据该终端设备需要发送的数据包的数量为该终端设备分配上行资源。
进一步的，h个终端设备中进行BSR上报的终端设备可以是接入网设备指示的，例如，接入网设备可以指示该h个终端设备中的一个或多个终端设备上报BSR，指示剩余的终端设备不上报BSR。其中，接入网设备具体的指示方式，这里不做具体限定。例如，接入网设备可以通过第三指示信息指示发送BSR，通过第四指示信息指示不发送BSR。又例如，接入网设备也可以通过第三指示信息指示发送BSR，通过不发送第三指示信息的方式隐式指示不发送BSR。又例如，接入网设备也可以通过第四指示信息指示不发送BSR，通过不发送第四指示信息的方式隐式指示发送BSR。
一种具体的实现方式中，第四指示信息可以用于指示对于某些特定的逻辑信道组(该逻辑信道组用于传输第一业务)，如果有新数据到达或者有更高优先级的数据到达时，无需触发BSR。如果是其他逻辑信道组中的逻辑信道触发的BSR，在上报的时候也无需上报上述特定的逻辑信道组的数据量。进一步的，第四指示信息还可以指示出哪些逻辑信道或者逻辑信道组无需触发BSR，例如可以通过在第四指示信息中携带相应的逻辑信道号或者逻辑信道组号码指示是否需要触发BSR。
可选的，第四指示信息可以通过MAC CE发送。或者，第四指示信息也可以通过RRC重配消息发送，例如，可以携带在RRC重配消息的配置逻辑信道或逻辑信道组配置中，用于指示是否需要触发BSR，或者携带在其他配置信息中。
第三指示信息可以指示正常触发BSR。对于正常上报BSR的终端设备来说，可以上报全部数据的数据量(即包括不需要该终端设备发送的数据包)，也可以仅上报需要该终端设备传输的数据量。所述第三指示信息可以是通过MAC CE发送的或者RRC消息发送的。
上述方法一中，由于接入网设备已经向终端设备下发了数据传输规则，而且该h个终端设备接收到第一业务的数据包相同，所以接入网设备根据任意一个终端设备上报的BSR可以推断出该h个终端设备对应的数据量，然后可以根据对应的数据量为每个终端设备分配上行资源，从而可以提升资源分配的准确性，从而可以降低多次上报BSR导致的信令开销。
方法二，h个终端设备将接收到的第一业务的数据包全部进行缓存，且该h个终端设备根据数据传输规则确定接收到的第一业务的数据包中需要自己发送的数据包(即待发送数据包)的数量。该h个终端设备分别向接入网设备上报BSR，且每个终端设备发送的BSR指示该终端设备的待发送数据包的数量而不是缓存的数据包总量。
例如，UE1和UE2均接收到第一业务的编号为1～4的数据包并缓存，而接入网设备指示数据包1和3由UE1发送，数据包2和4由UE2发送，则UE1上报的BSR的数据量为数据包1加数据包3的大小之和，UE2上报的BSR的数据量为数据包2加数据包4的大小之和。
上述方法二中，终端设备可以根据数据传输规则确定自己的数据量，从而可以BSR上报时指示自己需要发送的数据量，也就是在BSR组装过程中计算逻辑信道组数据量的时候，无需将接收到的第一业务的所有数据包都计算进去，而是只计算根据数据传输规则需要本终端设备需要传输的数据包对应的数据量，使得接入网设备可以根据终端设备需要传输的数据包对应的数据量为该终端设备分配上行资源，从而可以提升资源分配的准确性，减少不必要的上报，进而可以避免资源浪费。
方法三，h个终端设备根据数据传输规则确定接收到的第一业务的数据包中需要自己发送的数据包，并将需要自己发送的数据包进行缓存。该h个终端设备分别向接入网设备上报BSR，且一个终端设备发送的BSR指示该终端设备的待发送数据包的数量。
例如，UE1和UE2均接收到第一业务的编号为1～4的数据包，而接入网设备指示数据包1和3由UE1发送，数据包2和4由UE2发送，则UE1缓存数据包1和3，并向接入网设备上报BSR，上报的BSR的数据量为数据包1加数据包3的大小之和。UE2缓存数据包2和4，并向接入网设备上报BSR，上报的BSR的数据量为数据包2加数据包4的大小之和。
上述方法三中，终端设备可以根据数据传输规则确定自己的数据量，并且只缓存需要自己发送的数据包，从而可以BSR上报时指示自己需要发送的数据量，也就是在BSR组装过程中计算逻辑信道组数据量的时候，无需将接收到的第一业务的所有数据包都计算进去，而是只计算根据数据传输规则需要本终端设备需要传输的数据包对应的数据量，使得接入网设备可以根据终端设备需要传输的数据包对应的数据量为该终端设备分配上行资源，从而可以提升资源分配的准确性，并且可以提升终端设备存储资源的利用率，从而可以降低资源浪费。
可选的，上述方法一～方法三中，该h个终端设备缓存了第一业务的数据包后，可以 在PDCP层为每一个数据包启动一个相关联的丢弃定时器，当丢弃定时器超时以后，才将相应的数据包丢弃，而在丢弃定时器超时之前，缓存中的数据包可以根据接入网设备的指示进行初传或者重传。
一种具体实施方式中，终端设备采用方法二还是方法三进行BSR上报可以依赖于接入网设备的指示，例如，终端设备可以默认将接收到数据包都进行缓存(即默认为方法二)，若接入网设备指示仅缓存需要发送的数据包(即指示方法三)时，终端设备可以将不需要发送的数据包都丢弃掉。示例性的，接入网设备可以通过MAC CE指示终端设备采用方法二或者方法三。
本申请实施例中基于接入网侧的控制，使得第一业务的数据可以按照配置的数据传输规则在N个终端设备上进行传输，并且接入网设备可以灵活配置数据传输规则，例如接入网设备可以根据第一业务的业务需求、终端设备的空口质量、终端设备的工作状态等确定数据传输规则，使得N个终端设备可以根据业务需求或者空口质量实现备份或者分流的功能，从而可以配置满足第一业务的高可靠性、高速率等需求的数据传输规则，提高第一业务的传输性能。
并且，通过增强PDCP层，使得终端设备侧的PDCP层支持根据上层数据包的上层序号为数据包编排序号，或者，通过在应用层和接入层之间引入新的一层叫适配层，使得终端设备侧可以支持根据上层数据包的上层序号为数据包编排序号，或者，通过增强SDAP层，使得终端设备侧的SDAP层支持根据上层数据包的上层序号为数据包编排序号，从而可以实现应用层到接入层数据的统一数据编排序号。
相应的，接入网设备侧的PDCP层支持重排序和去重功能，或者，接入网设备侧的适配层可以支持重排序和去重功能，或者，接入网设备侧的SDAP层支持重排序和去重功能，可以使得接入网设备到核心网设备之间只发送一份数据，而没有重复和乱序等情况。
此外，本申请实施例中当终端设备需要发送的数据包出现丢包时，其他终端设备可以在发送自己需要发送的数据包之外还可发送上述丢包的数据包，从而可以提高业务的可靠性。
此外，本申请实施例中在BSR上报机制中，接入网设备可以根据终端设备需要发送的数据包的数据量分配上行资源，从而可以避免为终端设备分配过多或过少的传输资源，进而可以提高资源分配的合理性，提升资源利用率。
如图12A所示，为本申请提供的另一种通信方法的流程示意图，该方法包括：
S1201，核心网设备向接入网设备发送第一信息，第一信息指示第一业务的QoS需求。
示例性的，第一信息可以包括但不限于：5G QoS指示符(5G QoS identifier，5QI)信息、分配保持优先级(allocation and retention priority，ARP)、保证比特速率(guaranteed bit rate，GBR)、聚合最大比特速率(aggregate maximum bit rate，AMBR)。其中，5QI信息可以包括动态5QI信息和非动态5QI信息中的至少一种，动态5QI信息可以理解为非标准化或者没有预配置的5QI，包括：优先级、数据包延迟预算、包错误率、5QI、延迟临界等参数，非动态5QI信息可以理解为标准化的或者预配置的5QI，包括：5QI、优先级等参数。当然，第一信息也可以包括其他QoS流信息，这里不做具体限定。
一种实现方式中，接入网设备与核心网设备在建立会话时可以接收上述第一信息。
示例性的，第一业务的呈现形式可以为但不限于：PDU会话，QoS flow等。
第一信息可以通过接入网设备与核心网设备之间的接口消息来传递，如NGAP消息， 如PDU会话资源建立请求消息，也可以通过高层信令来承载，高层信令可以为RRC消息如RRC重配，或者MAC CE。具体的第一信息也可以在DRB的配置中。
S1202，接入网设备确定N个终端设备中的至少一个终端设备(下面以其中的第一终端设备为例进行说明)实际对应的QoS需求。
其中，第一终端设备的QoS比第一业务的QoS需求低，例如该第一终端设备的优先级(如5QI信息中的优先级、ARP等)比第一业务的优先级低、该第一终端设备的速率(如GBR、AMBR等)比第一业务的速率低、或者该第一终端设备的5QI信息中的参数比第一业务的5QI信息中的参数低，N个终端设备与第一业务相关，N为大于1的整数。第一终端设备的QoS比第一业务的QoS需求低，可以理解为第一终端设备在传输时使用的参数配置低于第一业务本身QoS需求对应的参数配置。
可以理解，由于有N个终端设备与第一业务相关，通过降低N个终端设备中部分终端设备或全部终端设备的QoS，可以使得N个终端设备的平均QoS低于第一业务的QoS需求，从而N个终端设备可以以较少的资源传输第一业务，减少资源消耗。
对于“N个终端设备与第一业务相关”的说明、对于“N个终端设备”的说明、以及接入网设备确定N个终端设备与第一业务相关的方式可以参阅上述S402中的相关描述，这里不再重复赘述。
需要说明的是，本申请实施例中“终端设备的QoS”可以理解为终端设备传输第一业务的QoS。
步骤S1202中，接入网设备通过降低第一终端设备的QoS，可以降低第一终端设备传输第一业务的资源，从而可以降低资源消耗。
需要说明的是，步骤S1202可以是一个可选的步骤。
S1203，接入网设备根据第一终端设备实际对应的QoS需求配置第一终端设备的传输参数。
示例性的，传输参数可以包括：用于传输第一业务的第一MCS、用于传输第一业务的时频资源的数量、用于传输第一业务的重复传输次数、PDCP复制传输指示等等。其中，PDCP复制传输指示用于指示传输第一业务时是否开启PDCP复制传输，PDCP复制传输可以理解为将一个PDCP包传输给两个RLC实体，两个RLC实体独自处理接收到的PDCP包并传输给MAC层。传输参数可以满足如下至少一项：
第一MCS可以高于第二MCS，其中，第一MCS为第一终端设备用于传输第一业务的MCS，第二MCS可以满足第一业务的QoS需求。可以理解的，MCS越低，需要更多的资源进行传输，上述方式通过为第一终端设备配置更高的MCS，可以减少资源消耗，提升资源利用率；
第一终端设备用于传输第一业务的时频资源的数量可以小于第一值，其中，数量为第一值的时频资源满足第一业务的QoS需求。可以理解的，数据传输速率越高，需要更多的资源进行传输，上述方式通过为第一终端设备配置更少的时频资源，从而可以减少资源消耗，提升资源利用率；
第一终端设备用于传输第一业务的重复传输次数的值可以小于第二值，其中，取值为第二值的重复传输次数可以满足第一业务的QoS需求。可以理解的，重复传输次数越高，需要更多的资源进行传输，上述方式通过为第一终端设备配置更低的重复传输次数，可以减少资源消耗，提升资源利用率；
PDCP复制传输指示用于指示不使用PDCP复制传输。上述方式不需要多份数据同时传输，可以减少资源消耗。
S1204，第一终端设备根据接入网设备配置的传输参数传输第一业务。
相比于图2所示的传输方式中N个终端设备传输第一业务需要消耗N倍空口资源、传输资源、站点的处理资源以及UE的功率资源等，本申请中，通过降低第一终端设备的QoS，可以降低第一终端设备传输第一业务的资源(如空口资源等)消耗，从而降低N个终端设备传输第一业务需要消耗的资源数量。并且，本申请中通过多个终端设备传输第一业务，可以获取分级增益，从而实现第一业务的可靠性。
一种可能的实施方式中，若第一终端设备成功发送第一业务的第一数据包，其他终端设备在传输第一数据包失败时可以不对该第一数据包进行重传。一种实现方式中，接入网设备接收到来自第一终端设备的第一数据包，若第二终端设备发送第一数据包失败，接入网设备可以向该第二终端设备发送指示信息，该指示信息可以指示第二终端设备不重传第一数据包。另一种实现方式中，接入网设备接收到来自第一终端设备的第一数据包，若第二终端设备发送第一数据包失败，接入网设备向该第二终端设备发送的PDCP状态报告中第一数据包的状态可以为成功发送。通过上述方式，可以进一步降低资源消耗。另一种实现方式中，接入网设备接收到来自第一终端设备的第一数据包，若第二终端设备发送第一数据包失败，接入网设备可以向该第二终端设备发送ACK指示或者不发送重传指示，可以实现第二终端设备不重传第一数据包，以减少资源消耗。
接入网设备在接收到N个终端设备的数据包后可以向核心网设备进行发送。具体的，接入网设备可以将来自N个终端设备的数据包进行去重和重排序后发送给核心网设备。通过上述方式，可以使得接入网设备到核心网设备之间只发送一份数据，且没有重复和乱序等情况。
或者，接入网设备也可以将来自N个终端设备的数据包分别独立的发送给核心网设备。进一步的，核心网设备可以将来自N个终端设备的数据包进行去重和重排序后发送给服务器，通过上述方式，可以使得核心网设备到服务器之间只发送一份数据，且没有重复和乱序等情况。或者，核心网设备也可以将来自N个终端设备的数据包分别独立的发送给服务器，服务器在接收到来自N个终端设备的数据包后进行去重和重排序。
其中，本申请中去重和重排序的过程(如接入网设备进行去重和重排序的过程、核心网设备进行去重和重排序的过程、服务器进行去重和重排序的过程)可以参阅上述步骤S404中进行去重和重排序的过程，这里不再重复赘述。
上文以第一终端设备为例介绍了N个终端设备传输第一业务的方式。N个终端设备基于上述方式传输第一业务的过程中，可能会出现部分终端设备的工作状态异常(例如终端设备故障、负载过大等)，针对这种情况，本申请中提供一种可能的解决方式，下面以第一终端设备工作异常为例进行说明。
接入网设备在确定第一终端设备工作异常时可以提升至少一个未发生工作异常的终端设备的QoS。一种具体的实现方式中，若未发生工作异常的终端设备的数量大于1，可以维持未发生工作异常的终端设备的QoS不变，或者，提升未发生工作异常的终端设备中全部终端设备或者部分终端设备的QoS但经过提升后的未发生工作异常的终端设备的平均QoS仍然低于第一业务的QoS需求。若未发生工作异常的终端设备的数量等于1，可以提升该终端设备的QoS，使得该终端设备的QoS满足第一业务的QoS需求。
其中，接入网设备确定终端设备的工作状态的方式可以为：其他终端设备向接入网设备上报上述终端设备正常工作或出现故障、上述终端设备上报自己的负载情况和/或干扰情况。其中，其他终端设备可以通过终端设备之间的心跳包或者终端设备之间的其他接口判断上述终端设备处于故障状态或者非正常工作状态。
接入网设备确定终端设备的工作状态的方式还可以为：接入网设备可以根据终端设备上行的数据传输情况，参考信号传输情况以及ACK反馈情况或者参考信号来判断终端设备的链路或者设备出现故障。
一种实现方式中，接入网设备可以通过如下四种方式中至少一种方式提升终端设备的QoS：
方式一，接入网设备降低终端设备用于传输第一业务的MCS。
方式二，接入网设备增加终端设备用于传输第一业务的时频资源。
方式三，接入网设备提升终端设备用于传输第一业务的重复传输次数。
方式四，接入网设备配置终端设备使用PDCP复制方式传输第一业务。
在图12A所述通信方法中，与图4～图11所述方法相关的参数定义和步骤可以参阅图4～图11中的相关描述，重复之处不再赘述。
本申请中，通过降低N个终端设备的QoS，使得N个终端设备传输第一业务时消耗的资源小于一个终端设备针对第一业务消耗的资源的N倍，从而可以降低资源消耗。并且，当出现终端设备故障时，通过提升剩余终端设备的QoS，可以在一定程度上保证第一业务的可靠性。
