Description

一种通信方法及相关设备
本申请要求于2019年06月06日提交中国专利局、申请号为201910492216.7、申请名称为“一种通信方法及相关设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，并且更具体地，涉及一种通信方法及相关设备。
背景技术
现有机制中，终端设备在与无线接入网设备传输数据之前，终端设备需要与无线接入网设备建立无线资源控制(radio resource control，RRC)连接，之后无线接入网设备通过RRC重配置消息给终端设备发送数据无线承载(data radio bearer，DRB)的配置信息，终端设备和无线接入网设备根据所述DRB的配置信息分别建立用于二者进行通信的DRB，从而使得终端设备可以使用所建立的DRB与该无线接入网设备进行数据传输，进而使得终端设备能够通过该无线接入网设备与核心网设备进行数据传输。在现有机制中，根据终端设备是否与无线接入网设备建立RRC连接，终端设备的状态包括：RRC连接态、RRC空闲态和第三态。其中，RRC连接态指终端设备已经与接入网建立RRC连接；RRC空闲态指终端设备未与无线接入网设备建立RRC连接；第三态介于RRC连接态和RRC空闲态之间，此时终端设备与无线接入网设备未建立RRC连接，但是无线接入网设备和核心网设备针对该终端设备的通道仍然保留。其中，所述第三态在新无线(new radio，NR)通信系统中又可被称为非激活态(inactive)。当UE处于RRC连接态时，UE和基站之间有RRC连接，基站和核心网之间有专用的控制面连接和用户面隧道。当UE处于RRC非激活态时，UE和基站之间没有RRC连接，但源基站和核心网之间有专用的控制面连接和用户面隧道。当UE处于空闲(idle)态时，UE和基站之间没有RRC连接，基站和核心网之间也没有专用的控制面连接和用户面隧道。
为了减少终端设备在与无线接入网设备通信前，等待终端设备与无线接入网设备建立RRC连接的时间，第三代合作伙伴计划(third generation partnership project，3GPP)的技术规范在LTE通信系统中定义了数据早传(early data transmission，EDT)技术。具体地，EDT技术支持用户面(user plane，UP)数传方案和控制面(control plane，CP)数传方案。其中，UP方案允许RRC非激活态的终端设备在向无线接入网设备发送RRC连接恢复请求或者随机接入前导码时携带加密的通信数据，无线接入网设备获取终端设备的上下文(UE context)并对通信数据进行解密后，从而根据终端设备的上下文，通过无线接入网设备与核心网设备之间专用的用户面隧道，将通信数据发送至核心网。CP方案允许RRC空闲态或RRC非激活态终端设备将通信数据携带在非接入层(non-access stratum，NAS)消息中，使得终端设备可以通过无线接入网设备将携带通信数据的NAS消息发送至核心网。EDT技术能够使得通信系统中处于RRC空闲态或RRC非激活态的终端设备，在没有与无线接入网设备建立RRC连接的情况下，向无线接入网设备发送通信数据。

虽然，EDT技术中的UP面方案，在无线接入网设备保存有终端设备的上下文的情况下，无线接入网设备在收到终端设备发送的通信数据后，就可以直接将终端设备的通信数据发送给核心网，但是，对于无线接入网设备没有保存终端设备的上下文的情况，该无线接入网设 备在接收端终端设备的通信数据后，在将该通信数据发送给核心网之前，无线接入网设备还需要通过例如源无线接入网设备获取终端设备的上下文，并通过向核心网设备发送路径改变(path switch)消息，以便无线接入网设备和核心网设备之间建立用户面隧道。当无线接入网设备与核心网设备之间建立用户面隧道后，无线接入网设备才能通过所建立的用户面隧道将通信数据发送至核心网设备，这就造成了RRC空闲态或RRC非激活态的终端设备在基于EDT技术与无线接入网设备通信过程中，终端设备向核心网设备发送通信数据时，仍然存在由于等待无线接入网设备获取该终端设备的上下文，和/或，建立该终端设备对应的无线接入网设备和核心网设备之间的用户面隧道而存在的端到端时延。对于EDT技术中的CP面方案，虽然CP面方案不需要通过基站和核心网之间的专用用户面隧道传输数据，即基站收到携带用户面数据的NAS消息后直接通过控制面将NAS消息送到核心网，不存在UP面提到的由于path switch以及建立专用用户面隧道带来的时延。但是CP面方案无法实现对不同slice的用户面数据进行区分和不同优先级处理。
因此，本申请提出网络切片对应的(slice specific)或者业务对应的(service specific)的数据无线承载(data radio bearer，DRB)的技术。无线接入网设备针对不同的网络切片或者服务，发送与网络切片或服务对应的DRB的配置信息，使得所有工作在相同网络切片的终端设备在不经过RRC连接建立以及RRC重配置流程的情况下，均可以使用该网络切片对应的DRB进行与无线接入网设备之间的数据传输。因此可以将网络切片对应的DRB称为预配置DRB。同时假设无线接入网设备与核心网之间已经建立了该网络切片对应的用户面隧道，即无线接入网设备可根据DRB对应的用户面隧道将用户面数据发送至核心网，以使得未处于RRC连接态的终端设备在进行数据传输时，终端设备和核心网之间端到端时延大大减少的目的。因此DRB也可以被称为预配置DRB，为了简明起见，后文将网络切片或服务对应的DRB统一称为网络切片对应的DRB。对于连接态UE，也可以基于接入网设备提供的网络切片对应的DRB直接和接入网设备进行数据传输。

同时，还会针对每个网络切片建立核心网设备110与无线接入网设备120之间的用户面隧道。其中，针对网络切片1、2和3，无线接入网设备120与核心网设备110之间建立隧道0、隧道1、隧道2，从而使得终端设备130在使用网络切片对应的DRB进行数据传输时，当无线接入网设备120接收到终端设备130发送的用户面数据后，即可根据该网络切片对应的DRB识别对应的网络切片，从而找到网络切片对应的用户面隧道将终端设备130的用户面数据发送至核心网。例如：终端设备130在数据传输时使用网络切片1对应的DRB1将上行通信数据发送至无线接入网设备120后，无线接入网设备即可根据该DRB1识别对应的网络切片1，通过无线接入网设备120与核心网设备110之间的与网络切片1对应的用户面隧道1将终端设备130的上行通信数据发送至核心网设备110，从而减少了终端设备在进行数据传输时等待无线接入网设备120获取该终端设备的上下文，和/或，建立该终端设备对应的用户面隧道而存在的端到端(end to end，E2E)时延。
图2A为本申请所提出的网络切片对应的DRB技术的示意图，如图2A所示，对于处于无线接入网设备100的网络覆盖下的终端设备A、B、C、D和E，其中终端设备A为连接态用户，无线接入网设备侧为终端设备A建立对应的DRB0。其中终端设备B、C、D和E为非连接态用户，无线接入网设备100为终端设备B、C、D和E建立网络切片对应的DRB，该网络切片对应的DRB可以指的是在无线接入网设备侧，针对工作在相同网络切片的终端设备B、C、D和E的DRB是“通用”的，例如，在无线接入网设备侧，工作在网络切片1的终端设备E可以通过无线接入网设备侧针对终端设备B、C或D的网络切片1对应的DRB与无线接入网设备100通信，也可以说，该终端设备E、B、C和D针对相同网络切片的无线接入网设备侧的网络切片对应的DRB是共享的。
可选的，如图2B所示的一种示例性的实施例A，无线接入网设备100在无线接入网设备侧为终端设备E、B、C和D生成共享网络切片对应的DRB，可以是“统一DRB”。示例性的，无线接入网设备100在无线接入网设备侧生成了网络切片对应的DRB之后，，后续其他终端设备B、C和D如果想工作在该网络切片对应的DRB上，由于之前无线接入网设备100在无线接入网设备侧该网络切片对应的DRB可以被其他终端设备B、C和D共享，所以其他终端设备B、C和D可以直接使用该无线接入网设备侧网络切片对应的DRB与该无线接入网设备通信。
可选的，如图2B所示的一种示例性的实施例B，无线接入网设备100为终端设备E、B、C和D生成网络切片对应的DRB，可以是“UE专有DRB”，示例性的，无线接入网设备100在无线接入网设备侧为该终端设备E生成了网络切片对应的DRB，后续其他终端设备B、C和D如果想工作在网络切片对应的DRB上，同样需要无线接入网设备100在无线接入网设备侧生成对应其他终端设备B、C和D的该网络切片对应的DRB。其中，无线接入网设备100为该终端设备E和其他终端设备B、C和D配置网络切片对应的DRB所使用的DRB配置信息可以是相同的，例如，终端设备E和其他终端设备B、C和D的该网络切片对应的DRB配置信息中针对相同网络切片的服务质量QoS需求、控制资源集、物理上行控制信道资源、物理上行共享信道资源、随机接入前导码、传输优先级、逻辑信道标识，数据无线承载的标识，数据无线承载的各协议层的配置信息中的一个或多个可以是相同的。其中，该数据无线承载的各协议层的配置信息可以包括以下一种或多种：PDCP层配置、RLC层配置、MAC层配置、PHY配置。其中，服务质量QoS需求可以包括QoS模板(QoS profile)，QoS profile里面可以包含服务质量流标识(quality of service flow identifier，QFI)以及对应的QoS参数。
图3为本申请所应用的基于网络切片对应的DRB的共享区域方法的示意图，如图3所示， 终端设备300从第一无线接入网设备100的服务小区A移动至第二无线接入网设备200的服务小区B。其中，第一无线接入网设备100、第二无线接入网设备200、小区A和小区B在同一个共享区域C内。第一无线接入网设备100为终端设备300分配网络切片对应的DRB配置信息，并为终端设备300分配该网络切片对应的共享区域C的标识，当在一个共享区域C内的基站或者小区之间，终端设备发生基站或者小区的切换或者重选，不用重新获取并建立共享网络切片对应的DRB，示例性的，该终端设备300在服务小区A使用该第一无线接入网设备100配置的网络切片对应的DRB和第一无线接入网设备100通信，当该终端设备300移动到服务小区B，该终端设备仍然可以使用该第一无线接入网设备100配置的网络切片对应的DRB在服务小区B与第二无线接入网设备200通信。
下面将结合以下各实施例，对本申请进行更加详细说明。
图4是本申请提供的一种通信方法的流程示意图，下面将结合图4，对本申请实施例的技术方案进行具体的描述。示例性的，图4所对应的通信方法100可以包括：
操作101：无线接入网设备向终端设备发送第一消息。
该无线接入网设备向该终端设备发送第一消息，该第一消息可以包括：网络切片标识，该网络切片标识对应的数据无线承载DRB的配置信息。
可选的，如果网络切片和DRB不是一一对应的，例如所有网络切片都对应同一个DRB，则该第一消息可以不包括网络切片标识，或者说该第一消息包括与所有网络切片对应的数据无线承载DRB的配置信息。例如无线接入网设备在广播消息中广播DRBConfigforSlicing，其中DRBConfigforSlcing包含DRB的配置信息。即所有网络切片的数据都可以通过公共的预配置DRB进行传输。为了让基站侧识别是哪个网络切片的数据，UE可以在上行数据中携带网络切片标识，例如在MAC子头中增加网络切片标识。反之，无线接入网设备在给UE发送下行数据的时候，也可以携带网络切片标识。再例如，无线接入网设备在广播消息中广播DRBConfigforSlicing以及SlicingList。其中SlicingList中包含适用于所述DRBConfigforSlicing的所有网络切片标识列表。即只有出现在SlicingList中的网络切片标识对应的数据，才可以使用预配置的DRB发送给无线接入网设备。
除了广播消息之外，对于连接态终端设备，无线接入网设备也可以通过RRC消息，例如RRC重配置消息，给连接态终端设备发送所述网络切片标识和对应的DRB配置信息。
一种可能的情况是，连接态终端设备先向无线接入网设备发送第一请求消息，第一请求消息可以包含网络切片标识。第一请求消息用于请求无线接入网设备发送所述网络切片标识对应的DRB配置信息。另一种可能的情况是，连接态终端设备先向无线接入网设备发送网络切片标识和第一指示，其中第一指示用于指示无线接入网设备发送所述网络切片标识对应的DRB配置信息。无线接入网设备收到连接态终端设备的上述请求或指示后，给所述终端设备发送网络切片标识对应的DRB配置信息。
示例性的，该数据无线承载配置信息可以包括以下一种或多种：该网络切片的专用逻辑信道标识(logical channel Identifier，LCID)，该数据无线承载的标识，该数据无线承载的各协议层的配置信息，该网络切片的服务质量(quality of service，QoS)需求，该网络切片的控制资源集(control resource set，CORESET)，该网络切片的物理上行控制信道(physical uplink control channel，PUCCH)资源，该网络切片的物理上行共享信道(physical uplink shared channel，PUSCH)资源，该网络切片的随机接入(random access)前导码(preamble)，该网络切片的传输优先级(priority)。其中，该DRB的各协议层的配置信息包括以下一种或多种：PDCP层配置、RLC层配置、媒体接入控制层(media access control，MAC)层配置、 物理(physical，PHY)层。
例如无线接入网设备可能将LCID为1，2，3分别对应网络切片1，2，3，后续无线接入网设备识别数据携带的LCID可以判断对应的网络切片标识。例如接入网设备首先判断所述终端设备是否建立了RRC连接，若终端设备在没有和基站建立RRC连接的情况下，发送了携带逻辑信道标识为1,2,3的上行数据，则无线接入网设备可以根据所述逻辑信道标识识别对应的网络切片标识。对于连接态终端设备，假设无线接入网设备预留了LCID＝1,2,3为网络切片1,2,3使用，那么给连接态终端设备专有的DRB对应的LCID就从编号4开始，因此无线接入网设备也可以通过上行数据携带的逻辑信道标识识别对应的网络切片标识。
由于上行载波可以包括常规的上行(Uplink，UL)载波和补充上行(supplementary uplink，SUL)载波，本申请中的数据无线承载配置信息可以包括上行载波的数据无线承载配置信息，和/或，补充上行载波(supplementary uplink carrier，SUL)上的数据无线承载配置信息。
由于终端设备与网络设备之间的通信可以是单播通信，也可以是多播通信，或者是广播通信，本申请中的数据无线承载配置信息可以包括单播通信的数据无线承载配置信息，和/或，多播通信的数据无线承载配置信息，相应的，本申请中的网络切片对应的数据无线承载可以包括单播通信对应的网络切片数据无线承载，和/或，多播通信对应的网络切片对应的数据无线承载。
可选的，该DRB配置信息还可以包括网络切片共享标识，该网络切片共享标识用于：该无线接入网设备使用该数据无线承载与多个该终端设备进行组播通信时，在该共享区域内标识该多个终端设备。例如，该网络切片共享标识可以用于对小区范围或者共享区域范围的下行网络切片对应的组播业务进行加扰。
可选的，该DRB配置信息还包括该共享区域内的小区或无线接入网设备集合。该小区或无线接入网设备集合可以为发送相同的共享区域标识的小区或基站集合。
可选的，该第一消息不是一直周期性发送的，例如，只有终端设备请求(on demand)才会发送。
可选的，终端设备每移动到一个新的无线接入网设备覆盖范围下，终端设备可能会请求网络切片对应的DRB配置信息。示例性的，该无线接入网设备可以向该终端设备发送第二消息，该第二消息包括：第一指示信息；其中，该第一指示信息可以用于指示该第一消息是否发送；如果该第一指示信息指示该第一消息未发送，则该终端设备可以向无线接入网设备发送请求信息，该请求信息用于请求该无线接入网设备发送该第一消息。
可选的，终端设备每移动到一个新的无线接入网设备覆盖范围下，只有满足一定条件下，终端设备才会请求网络切片对应的DRB配置信息，该条件可以如下所述：
示例性的，该无线接入网设备还向该终端设备发送第三消息，该第三消息可以包括共享区域的标识；如表1的广播消息形式1所示，该共享区域可以与所有网络切片对应，即该共享区域内每个小区只广播该共享区域的同一个标识，该共享区域标识与所有网络切片标识对应；示例性的，在该共享区域，相同的网络切片具有相同的DRB配置信息。或者如表1的广播消息形式2所示，该共享区域可以与特定网络切片标识对应，即每个小区会广播的一个或多个该共享区域标识，分别与一个或多个网络切片标识对应，不同的网络切片标识可以对应同一个共享区域标识，也可以对应不同的共享区域标识。示例性的，与同一个共享区域标识对应的所有的网络切片标识对应的网络切片具有相同的DRB配置。
表1：
Figure PCTCN2020094798-appb-000001
表1仅仅示出了几种可能的情况，其中，网络切片标识的一种形式为：单网络切片选择辅助信息S-NSSAI(Single Network Slice Selection Assistance Information)。上述广播消息的形式不限于表1所示的情况，例如其中的共享区域的标识也可以为共享区域的标识列表，在此不再赘述。
可选的，该第三消息也可以包括共享区域的标识和网络切片的标识，当共享区域与所有网络切片标识对应的时，该第三消息也可以只包括共享区域的标识。当终端设备接收到该第三消息后可以将该网络切片对应的共享区域与之前在别的小区内接收并存储的网络切片对应的共享区域对比，如果一样，则不用请求第一消息，如果不一样，则要请求第一消息，以获取当前共享区域内的与该网络切片对应的数据无线承载的配置信息。
可选的，该无线接入网设备向终端设备发送第四消息，该第四消息包括第二指示信息；该第二指示信息用于指示该网络切片对应的DRB是否为该共享区域内的数据无线承载。例如对于网络切片1对应的DRB1的配置信息，网络切片2对应的DRB2的配置信息。网络切片1对应第二指示，网络切片2没有对应的第二指示；或者网络切片1对应的第二指示为true，网络切片2对应的第二指示为false。即表示网络切片1对应的DRB1的配置信息在共享区域内相同，网络切片2对应的DRB2的配置信息仅在小区范围内适用。如果该第一指示信息指示该第一消息未发送，且当该第二指示信息指示该DRB不是该共享区域内的数据无线承载时(例如该DRB配置仅在小区范围内适用)，该终端设备向无线接入网设备发送请求信息，该请求信息用于请求该无线接入网设备发送该第一消息。如果该第一指示信息指示该第一消息未发送，且当该第二指示信息指示该数据无线承载是该共享区域内的数据无线承载时，该共享区域与所有网络切片标识对应或者与该网络切片标识对应，当该终端设备之前存储的与所有网络切片标识对应或者与该网络切片标识对应的共享区域的标识和第三消息中的共享区域的标识不同时，该终端设备向无线接入网设备发送请求信息，该请求信息用于请求该无线接入网设备发送该第一消息。其中，对于首次没有存储与该网络切片标识对应的共享区域的标识的情况，可以设置为不需要进行该终端设备存储的与所有网络切片标识对应或者与该网络切片标识对应的共享区域的标识和第三消息中的共享区域的标识的比较，就可以向无线接入网设备发送请求信息，该请求信息用于请求该无线接入网设备发送该第一消息。其中，该共享区域与所有网络切片标识对应还是与该网络切片标识对应，可以是协议或者标准规定的，也可以是通过信令预配置的，在此不再赘述。
可选的，该无线接入网设备向终端设备发送第四消息，该第四消息包括第二指示信息；该第二指示信息用于指示该网络切片对应的DRB为共享区域范围内适用数据无线承载还是小区范围内适用数据无线承载。例如对于网络切片1对应的DRB1的配置信息，网络切片2对应的DRB2的配置信息。网络切片1对应第二指示为指示该网络切片对应的DRB是共享区域范围内适用数据无线承载，网络切片2对应第二指示为指示该网络切片对应的DRB是小区范围内适用数据无线承载；或者网络切片1对应的第二指示为true，网络切片2对应的第二 指示为false。即表示网络切片1对应的DRB1的配置信息在共享区域内适用，网络切片2对应的DRB2的配置信息在小区范围内适用。如果该第一指示信息指示该第一消息未发送，且当该第二指示信息指示该网络切片对应的DRB是小区范围内适用数据无线承载，该终端设备向无线接入网设备发送请求信息，该请求信息用于请求该无线接入网设备发送该第一消息。如果该第一指示信息指示该第一消息未发送，且当该第二指示信息指示该网络切片对应的DRB是共享区域范围内适用数据无线承载，该共享区域与所有网络切片标识对应或者与该网络切片标识对应，则当终端设备接收到该第三消息后可以将该网络切片对应的共享区域与之前在别的小区内接收并存储的网络切片对应的共享区域对比，如果一样，则不用请求第一消息，如果不一样，则要请求第一消息，以获取当前共享区域内的与该网络切片对应的数据无线承载的配置信息。其中，对于首次没有存储与该网络切片标识对应的共享区域的标识的情况，可以设置为不需要进行该终端设备存储的与所有网络切片标识对应或者与该网络切片标识对应的共享区域的标识和第三消息中的共享区域的标识的比较，就可以向无线接入网设备发送请求信息，该请求信息用于请求该无线接入网设备发送该第一消息。其中，该共享区域与所有网络切片标识对应还是与该网络切片标识对应，可以是协议或者标准规定的，也可以是通过信令预配置的，在此不再赘述。
本申请中的“第一消息”，“第二消息”等，可以是广播消息，也可以是专有信令，例如可以是层1消息、层2消息、层3消息。示例性的，层1消息一般指的是PHY层消息，层2消息一般指的是MAC层，RLC层，或者PDCP层的信令，例如MAC层控制元素(media access control element，MAC CE)消息，层3消息一般指的是RRC层，或者非接入层(non-access stratum，NAS)层的信令，例如RRC消息或NAS消息。本申请中的“第一消息”，“第二消息”可以是包括在别的消息中的一部分信元(information element，IE)。
示例性的，该第一消息、第二消息可以为系统信息广播(system information block，SIB)消息。示例性的，该第二消息可以为SIB1消息，该SIB1消息包括的信息可以属于该无线接入网设备服务的小区的最小系统信息(minimum SI)，该第一消息可以属于该无线接入网设备服务的小区的其余系统信息(other SI)。
可选的，如果第一消息被配置为一直进行广播，则无线接入网设备可以不需要向终端设备发送第二消息。示例性的，该第一消息属于该无线接入网设备服务的小区的minimum SI。则此时，也可以等效理解为，对于该第一指示信息指示该第一消息未发送且该终端设备不向该无线接入网设备请求的上述前提情况，在上述前提情况下，即使该第一指示信息指示该第一消息发送，终端也可以选择忽略或者不解析该第一消息。
操作102：终端设备向无线接入网设备发送数据。
该终端设备可以根据该数据所属的或者所对应的网络切片确定对应的数据无线承载，再通过该无线承载的逻辑信道标识对应的逻辑信道向该无线接入网设备发送该数据，相应的，该无线接入网设备可以通过该逻辑信道标识对应的逻辑信道接收来自该终端设备的数据。
例如，在发送该数据时，终端设备根据该数据对应的网络切片，以及无线接入网设备发送的网络切片标识和DRB配置的映射关系，确定该网络切片对应的DRB的逻辑信道标识，然后终端设备会在封装该数据的协议层头中包含该数据无线承载对应的逻辑信道标识，例如在MAC头(或MAC子头)中包含所述逻辑信道标识。相应的，无线接入网设备可以在封装该数据的MAC头中获取所述数据所对应的逻辑信道标识，该无线接入网设备可以根据该数据包含的该逻辑信道标识找到对应的RLC实体和PDCP实体进行数据接收和处理。
操作103：无线接入网设备获取数据对应的网络切片标识，并在该切片标识对应的无线接 入网设备和核心网设备之间的用户面隧道上传输数据。
由于网络切片标识，LCID，DRB标识三者之间存在对应关系，因此无线接入网设备可以根据其中任一标识找到无线接入网设备和核心网设备之间的该网络切片对应的用户面隧道，后续在无线接入网设备和核心网之间与该网络切片对应的用户面隧道上传输该数据。
可选的，该无线接入网设备根据该数据无线承载或者数据无线承载标识获取该网络切片标识，再获取该无线接入网设备和核心网设备之间的该网络切片对应的用户面隧道；

可选的，该无线接入网设备根据接收到的数据中携带的网络切片标识获取对应的无线接入网设备和核心网设备之间的该网络切片对应的用户面隧道。
示例性的，如果网络切片和DRB是一一对应的，则无线接入网设备根据用于接收该数据的LCID或者DRB ID，获取该LCID或者DRB ID对应的网络切片，在该网络切片标识对应的无线接入网设备和核心网设备之间的用户面隧道上传输该数据。
示例性的，如果网络切片和DRB不是一一对应的，则终端设备上传的数据中需要携带网络切片标识，这样无线接入网设备通过该数据携带的网络切片的标识，可以在该网络切片标识对应的无线接入网设备和核心网设备之间的用户面隧道上传输该数据。

该第一GTP-U隧道地址信息和该第二GTP-U隧道地址信息用于标识该第一网络设备与该第二网络设备之间的该网络切片标识对应(或者该数据无线承载标识对应)的用户面隧道。
如果该第一网络设备与该第二网络设备之间的该网络切片标识对应(或者该数据无线承载标识对应)的用户面隧道同时用于单播和组播的数据传输，则第二网络设备需要在下行数据包的GTP-U头中增加是否多播的指示。例如如果没有多播指示(或者多播指示为false)，则对应的数据为单播；如果包含多播的指示(或者多播指示为true)，则对应的数据未多播。如果第一网络设备收到多播指示后，在多播通信对应的网络切片对应的数据无线承载上进行多播传输，如果第一网络设备收到单播指示后，在单播通信对应的网络切片对应的数据无线承载上进行单播传输。
