Description

通信方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
当前，终端设备和接入网设备之间以数据无线承载(data radio bearer，DRB)为粒度对传输的业务数据进行服务质量(quality of service，QoS)控制。接入网设备和用户面功能(user plane function，UPF)之间以QoS流(QoS flow)为粒度对传输的业务数据进行QoS控制。QoS流和DRB与该业务对应的QoS参数集合相关联。通信装置可以根据为业务预先配置的QoS参数，确定与该QoS参数集合关联的QoS流和DRB，并根据该QoS流和DRB对业务数据进行控制。
当业务的业务状态发生变化之后，业务的QoS需求也可能随之发生变化，此时为该业务预先配置的QoS参数将与业务的QoS需求不匹配，这将会影响通信网络的传输性能。

以上，对本申请的应用场景进行了简单介绍。
为了便于理解本申请实施例提供的技术方案，首先对本申请实施例中的部分用语进行解释说明。
1、PDU会话
参见图2，PDU会话是终端设备和DN之间的连接，用于提供PDU连接服务。其中，PDU会话类型可以是IP连接、以太网连接或者非结构数据连接等。5G系统的核心网支持的PDU连接服务，是指提供终端设备和由数据网络名称(data network name，DNN)确定的DN之间PDU交换的服务。终端设备可以发起建立一个或多个PDU会话，来连接到相同的DN或者不同的DN。例如，图2中，终端设备发起建立PDU会话1和PDU会话2，来连接到相同的DN。
2、QoS流
QoS流是PDU会话中最精细的QoS区分粒度，一个QoS流标识(QoS flow identity，QFI)用于标识一个QoS流。一个PDU会话可以包括多个QoS流，每个QoS流可以承载多个业务。
在当前的通信系统中，在接入网设备和核心网设备之间，接入网设备和核心网设备以QoS流为粒度对传输的业务数据进行QoS控制。
具体来说，在下行传输过程中，UPF根据目标业务的QoS需求，确定目标业务对应的QoS流。UPF将目标业务的下行数据映射到该目标业务对应的QoS流上，向接入网设备发送目标业务的下行数据。
在上行传输过程中，接入网设备根据接收来的来自终端设备的目标业务的上行数据，确定目标业务对应的QoS流。接入网设备将目标业务的上行数据映射到该目标业务对应的QoS流上，向UPF发送目标业务的上行数据。
3、DRB
在当前的通信系统中，在终端设备和接入网设备之间，终端设备和接入网设备以DRB为粒度对传输的业务数据进行QoS控制。
具体来说，在下行传输过程中，接入网设备接收到来自UPF的目标业务的下行数据之后，根据该目标业务的下行数据对应的QoS流，确定该QoS流对应的DRB。接入网设备在该QoS流对应的DRB上，向终端设备发送目标业务的下行数据。
在上行传输过程中，终端设备根据目标业务的QoS需求，确定目标业务对应的QoS流，并根据目标业务的上行数据对应的QoS流，确定该QoS流对应的DRB。终端设备在该QoS流对应的DRB上，向接入网设备发送目标业务的上行数据。
4、QoS流与DRB之间的对应关系
目前，一个QoS流对应一个QoS参数，一个QoS参数对应一个DRB，因此，一 个QoS流对应一个DRB。此外，一个DRB可以对应一个或多个QoS参数，因此。一个DRB对应一个或多个QoS流。
需要指出的是，QoS流与DRB之间的对应关系可以由接入网设备配置，在接入网设备配置完成该对应关系之后，接入网存储该对应关系，并向终端设备发送该对应关系。接入网设备和终端设备可以根据该对应关系，将QoS流上的数据映射到DRB上，根据该DRB传输数据。其中，一个QoS流对应一个DRB，一个DRB对应一个或多个QoS流。
5、QoS参数集合
QoS参数集合包括一下至少一项：5G QoS标识(5G QoS Identifier，5QI)、分配与预留优先级、反射QoS属性、保证流比特率、最大流比特率、通知控制和最大丢包率。
在上述参数中，5QI是一个整数，每个整数取值对应一个QoS特征(QoS characteristic)，其内容包括资源类型、优先级、数据包时延预算、数据包错误率、平均窗口、最大突发数据量等。
6、数据包过滤器集合
一个数据包过滤器集合包括一个或多个数据包过滤器。数据包过滤器包括一个或多个数据包过滤规则。数据包过滤器用于对数据进行过滤，符合数据包过滤器规则的数据能够通过该数据包过滤器，不符合数据包过滤器规则的数据不能够通过该数据包过滤器。对于数据包过滤器集合来说，符合数据包过滤器集合中的任一个数据包过滤器中的数据包过滤规则的数据包，均能够通过该数据包过滤器集合。
一个数据包过滤器集合对应一个QoS流。一个QoS流对应一个或多个数据包过滤器集合。
数据包过滤器集合能够将通过该数据包过滤器集合的数据包，映射到该数据包过滤器集合对应的QoS流上。通过该数据包过滤器集合的数据包将承载在该数据包过滤器集合对应的QoS流上进行传输。
举例来说，用于过滤IP数据包的数据包过滤器的参数包括以下至少一项：源/目的IP地址，源/目的端口号，协议标识，服务类型，流标签，安全参数索引。与数据包过滤器的参数一致的数据包能够通过该数据包过滤器。
在IP数据包达到通信装置之后，通信装置调用多个数据包过滤器集合对该IP数据包进行过滤，确定该IP数据包能够通过的数据包过滤器。通信装置将该IP数据包映射到该过滤器所属的数据包过滤器集合对应的QoS流上。通信装置在该QoS流上传输该IP数据包。
需要指出的是数据包过滤器包括上行数据包过滤器和下行数据包过滤器。数据包过滤器集合包括上行数据包过滤器集合和下行数据包过滤器集合。上行数据包过滤器和上行数据包过滤器集合用于过滤上行数据；下行数据包过滤器和下行数据包过滤器集合用于过滤下行数据；其具体实现过程可以参照上述描述，本申请对此不在赘述。
以上是对本申请涉及到的部分内容以及概念所作的简单介绍。
目前，为了解决业务的QoS需求发生变化后，预先为该业务配置的QoS参数与业 务的QoS需求不匹配的问题，提供了一种QoS重配置的方法。具体为，控制面网元SMF对通信装置中与该业务对应的QoS配置信息进行重新配置，将为该业务配置的QoS参数调整为与该业务变化后的QoS需求相匹配的QoS参数。SMF重新配置与该QoS参数关联的QoS流以及DRB。在配置完成之后，通信装置根据重新配置的QoS配置信息对该业务的业务数据进行QoS控制。
上述方法虽然能根据业务的QoS需求调整QoS参数，但是该方法需要从控制面重新配置QoS配置信息，配置过程耗时较长，无法适用于QoS需求随时间快速变化的业务。
为了保证这些QoS需求随时间快速变化的业务的QoS需求，SMF将该业务的QoS参数配置为与该业务的最高QoS需求相匹配的QoS参数，并以该QoS参数关联的DRB和QoS流对该业务的业务数据进行控制。
该方法虽然能保证业务的QoS需求，但是在业务处于较低的QoS需求时，通信网络为该业务提供的QoS将会大于业务的QoS需求，造成了通信网络的网络资源的浪费。
为了解决上述技术问题，本申请实施例提供了一种通信方法及装置，当目标业务在不同业务状态下的QoS需求不同的情况下，SMF根据目标业务不同的QoS需求，分别为各个QoS需求配置相应的QoS参数，并将该多个QoS参数关联到一个QoS流上。
在上行传输过程中，终端设备在根据目标业务当前的业务状态，确定目标业务对应的QoS参数集合，终端设备在该QoS参数集合对应的DRB上，向接入网设备发送上行数据。
这样，终端设备可以实时的根据目标业务的QoS需求(对应于业务状态)的变化，确定目标业务相应的QoS参数集合，并在该QoS参数集合对应的DRB上，向接入网设备发送目标业务的上行数据。在目标业务的QoS需求变化较快的情况下，终端设备可以实时的根据目标业务的QoS需求调整目标业务的QoS参数，提高了QoS参数与业务的QoS需求的匹配度，并且在满足目标业务的QoS需求的情况下，避免通信网络的网络资源浪费。
在下行传输过程中，UPF根据目标业务当前的业务状态，确定目标业务对应的QoS参数集合，UPF在该QoS参数集合对应的QoS流上，向接入网设备发送下行数据。
这样，UPF可以实时的根据目标业务的QoS需求的变化，确定目标业务相应的QoS参数集合，并在该QoS参数集合对应的QoS流上，向接入网设备发送目标业务的下行数据。在目标业务的QoS需求变化较快的情况下，UPF可以实时的根据目标业务的QoS需求调整目标业务的QoS参数，提高了QoS参数与业务的QoS需求的匹配度，并且在满足目标业务的QoS需求的情况下，避免通信网络的网络资源浪费。
以下，对本申请提供的通信方法进行详细描述。在不同传输场景下，本申请提供的通信方法的实现过程不同，以下分别进行描述。其中，传输场景包括上行传输场景(记为场景1)和下行传输场景(记为场景2)。
场景1、上行传输场景
在该场景下，如图3所示，本申请实施例提供的通信方法包括：
S301、终端设备在第一QoS参数集合对应的DRB上，向接入网设备发送目标业 务的第一上行数据。相应的，接入网设备接收来自终端设备的第一上行数据。
其中，第一QoS参数集合为第一QoS流对应的多个QoS参数集合中，与第一上行数据的QoS需求对应的QoS参数集合；第一QoS流为用于传输目标业务的上行数据的QoS流。第一上行数据为终端设备确定的目标业务当前的上行数据。
下面，对目标业务的QoS需求，QoS参数集合，第一QoS流，以及DRB之间的对应关系进行说明：
目标业务具有多个QoS需求，且目标业务被配置有多个QoS参数集合，一个QoS需求对应一个QoS参数集合。目标业务在不同QoS需求下，可以对应不同的QoS参数集合。
目标业务对应的第一QoS流包括上述为目标业务配置的多个QoS参数集合，且第一QoS流在同一个时间点上对应该多个QoS参数集合中的一个QoS参数集合。第一QoS流在不同的时间点上对应的QoS参数集合可以不同。
一个QoS参数集合对应一个DRB，一个DRB可以对应一个或多个QoS参数集合。
基于上述对应关系，一种可能的实现方式中，终端设备确定目标业务当前的QoS需求，并根据目标业务当前的QoS需求，确定目标业务当前对应的QoS参数集合(记为第一QoS参数集合)。终端设备在第一QoS参数集合所对应的DRB上，向接入网设备发送目标业务的第一上行数据。
S302、接入网设备在第一QoS流上根据第一QoS参数集合，向UPF发送第一上行数据。相应的，UPF接收来自接入网设备的第一上行数据。
一种可能的实现方式中，在接入网设备接收到来自终端设备的第一上行数据之后，接入网设备确定该第一上行数据对应的第一QoS参数集合。接入网设备确定第一QoS参数集合所属的第一QoS流。接入网设备在第一QoS参数集合所属的第一QoS流上，根据第一QoS参数集合向UPF发送第一上行数据。
基于上述技术方案，在本申请实施例提供的通信方法中，当目标业务在不同业务状态下的QoS需求不同的情况下，SMF根据目标业务不同的QoS需求，分别为各个QoS需求配置相应的QoS参数，并将该多个QoS参数关联到一个QoS流上。
在上行传输过程中，终端设备在根据目标业务当前的业务状态，确定目标业务对应的QoS参数集合，终端设备在该QoS参数集合对应的DRB上，向接入网设备发送上行数据。
这样，终端设备可以实时的根据目标业务的QoS需求(对应于业务状态)的变化，确定目标业务相应的QoS参数集合，并在该QoS参数集合对应的DRB上，向接入网设备发送目标业务的上行数据。接入网设备在该QoS参数集合所属的QoS流上根据该QoS参数集合向UPF发送目标业务的上行数据。在目标业务的QoS需求变化较快的情况下，终端设备可以实时的根据目标业务的QoS需求调整目标业务的QoS参数，提高了QoS参数与业务的QoS需求的匹配度，并且在满足目标业务的QoS需求的情况下，避免通信网络的网络资源浪费。
场景2、下行传输场景
在该场景下，如图4所示，本申请实施例提供的通信方法包括：
S401、UPF在第一QoS流上根据第一QoS参数集合，向接入网设备发送第一下 行数据。相应的，接入网设备接收来自UPF的第一下行数据。
其中，第一QoS流为用于传输目标业务的下行数据的QoS流；第一QoS参数集合为第一QoS流对应的多个QoS参数集合中，与第一下行数据的QoS需求对应的QoS参数集合。
一种可能的的实现方式中，UPF确定目标业务当前的QoS需求，并根据目标业务当前的QoS需求，确定目标业务的当前对应的QoS参数集合(记为第一QoS参数集合)。UPF在第一QoS参数集合所属的第一QoS流上根据第一QoS参数集合，向接入网设备发送第一下行数据。
S402、接入网设备在第一QoS参数集合对应的DRB上，向终端设备发送第一下行数据。
其中，目标业务的QoS需求，QoS参数集合，第一QoS流，以及DRB之间的对应关系可以参照上述S301中的说明，此处不再赘述。
基于上述技术方案，在本申请实施例提供的通信方法中，当目标业务在不同业务状态下的QoS需求不同的情况下，SMF根据目标业务不同的QoS需求，分别为各个QoS需求配置相应的QoS参数，并将该多个QoS参数关联到一个QoS流上。
在下行传输过程中，UPF根据目标业务当前的业务状态，确定目标业务对应的QoS参数集合，UPF在该QoS参数集合对应的QoS流上，向接入网设备发送下行数据。
这样，UPF可以实时的根据目标业务的QoS需求的变化，确定目标业务相应的QoS参数集合，并在该QoS参数集合对应的QoS流上，向接入网设备发送目标业务的下行数据。接入网设备根据在该QoS参数集合对应的DRB上向终端设备发送目标业务的下行数据。在目标业务的QoS需求变化较快的情况下，UPF可以实时的根据目标业务的QoS需求调整目标业务的QoS参数，提高了QoS参数与业务的QoS需求的匹配度，并且在满足目标业务的QoS需求的情况下，避免通信网络的网络资源浪费。
一种可能的实现方式中，本申请实施例所记载的第一QoS流的特征包括以下至少一项：特征1、第一QoS流对应多个QoS参数集合；特征2、第一QoS流对应两个标识；特征3、第一QoS流对应一个或多个DRB。上述特征适用于场景1和场景2中的任一个场景。下面，对第一QoS流的上述3个特征分别进行说明：
特征1、第一QoS流对应多个QoS参数集合。
具体来说，在QoS配置阶段，网络侧控制面为第一QoS流配置多个QoS参数集合。第一QoS流在同一个时间点上对应该多个QoS参数集合中的一个QoS参数集合。第一QoS流在不同的时间点上对应的QoS参数集合可以不同。第一QoS流具体对应多个QoS参数集合中的哪一个QoS参数集合，可以根据目标业务的QoS需求确定。
示例性的，如图5所示，第一QoS流共对应3组QoS参数集合，第一QoS流在第一时间段(t1和t2之间)对应的QoS参数集合为第1组QoS参数集合，第一QoS流在第二时间段(t2和t3之间)对应的QoS参数集合为第3组QoS参数集合，第一QoS流在第三时间段(t3和t4之间)对应的QoS参数集合为第2组QoS参数集合，第一QoS流在第四时间段(t4和t5之间)对应的QoS参数集合为第3组QoS参数集合。
基于上述特征1，本申请实施例提供的第一QoS流对应多个QoS参数集合，在目 标业务的QoS需求变化时，第一QoS流相应的调整为变化后的QoS需求对应的QoS参数集合。可以提高第一QoS流的QoS参数集合与目标业务的QoS需求的匹配度。
特征2、第一QoS流对应两个标识。
其中，该两个标识分别为第一标识QoS参数标识(QoS Parameter Identifier，QPI)，以及第二标识QFI。也即是说，第一QoS流的标识为(QFI，QPI)。
第一标识QPI用于表征第一QoS流对应的QoS参数集合。第一QoS流的QPI与第一QoS流对应的QoS参数集合一一对应。第一QoS流的QPI为可变标识，当第一QoS流对应的QoS参数集合发生变化时，第一QoS流的QPI相应的调整为变化后的QoS参数集合对应的QPI。
第二标识QFI与现有技术中QoS流标识QFI相同，关于第二标识QFI的理解可以参照现有技术，本申请对此不在赘述。
举例来说，结合图5的示例，第一QoS流的QFI为20，第一QoS流对应的3组QoS参数集合的QPI分别为1，2，3。
在第一时间段内，第一QoS流的标识为(QFI＝20，QPI＝1)。
在第二时间段内，第一QoS流的标识为(QFI＝20，QPI＝3)。
在第三时间段内，第一QoS流的标识为(QFI＝20，QPI＝2)。
在第四时间段内，第一QoS流的标识为(QFI＝20，QPI＝3)。
基于上述特征2，第一QoS流通过设置第一标识指示第一QoS流对应的QoS参数集合，可以使通信系统中的各个网元根据第一标识准确的确定第一QoS流对应的QoS参数集合。
特征3、第一QoS流与一个或多个DRB对应。
具体来说，第一QoS流对应的多个QoS参数集合中，每个QoS参数集合对应一个DRB，一个DRB对应一个或多个QoS参数集合。因此，该多个QoS参数集合可以对应一个或多个DRB。相应的，第一QoS流同样对应该多个QoS参数集合对应的一个或多个DRB。
例如，结合上述图5中的示例，第一QoS流中的第1组QoS参数集合和第2组QoS参数集合对应DRB#1，第3组QoS参数集合对应DRB#2。基于此，第一QoS流对应DRB#1和DRB#2。
基于上述特征3，终端设备和接入网设备可以根据目标业务对应的QoS参数集合，确定承载目标业务的DRB。
一种可能的实现方式中，目标业务的QoS需求，与目标业务的业务状态有关。
目标业务的业务状态指的是终端设备在根据目标业务进行通信时，目标业务的应用状态。
一种示例，当终端设备正在进行工业通信(也即目标业务为工业通信)时，目标业务的业务状态为该工业通信对应的工业应用的状态。此时终端设备可以为工业传感器或者工业控制器等。
例如，工业应用为工业控制时，该工业通信对应的业务状态可以为误差控制状态；误差控制状态包括以下任一项：高误差控制状态、中误差控制状态、低误差控制状态。
或者，目标业务的业务状态为控制系统稳定状态；控制系统稳定状态包括以下任 一项：稳定状态、非稳定状态。
又一种示例，当终端设备正在进行AR/VR通信(也即目标业务为AR/VR通信)时，目标业务的业务状态为该AR/VR通信对应的AR/VR应用的应用状态。此时，终端设备可以为AR/VR设备。
AR/VR通信的业务状态可以为以下任一项：新数据帧即将开始，数据帧突发数据量已经过去。
在本申请实施例中，终端设备，或者应用服务器用于感知目标业务的业务状态。在终端设备和应用服务器感知到目标业务的业务状态之后，可以采用枚举类型指示目标业务的业务状态。例如，用稳定和不稳定两种状态来指示工业应用的控制系统处于稳定状态或非稳定状态。
或者，终端设备和应用服务器也可以采用整数类型来指示目标业务的业务状态。例如，采用整数类型“0”指示工业应用的控制系统处于稳定状态，采用整数类型“1”指示工业应用的控制系统处于非稳定状态。
一种可能的实现方式中，在终端设备、接入网设备和UPF采用第一QoS流传输数据之前，本申请实施例提供的方法还包括预配置过程，用于在终端设备、接入网设备和UPF配置确定第一QoS流，以及第一QoS参数集合的规则。
其中，预配置过程可以通过以下方式1至方式4中的任意一种或多种方式实现：

其中，业务状态索引规则用于指示目标业务的业务状态与各个业务状态索引(index)之间的对应关系。本申请实施例所记载的业务状态索引也可以称为业务状态编号。
QoS规则用于指示QoS流在不同QoS参数集合下对应的上行数据包过滤器集合，以及各个上行数据包过滤器集合对应的业务状态索引。一个QoS规则对应一个QoS流。
在SMF向终端设备配置完成上述业务状态索引，以及一个或多个QoS规则之后，终端设备可以根据感知到的目标业务当前的业务状态，确定目标业务当前的业务状态索引。终端设备根据目标业务当前的业务状态索引，以及一个或多个QoS规则，确定目标业务当前对应的上行数据包过滤器集合。在此之后，终端设备确定该上行数据包过滤器集合对应的QoS参数集合，为目标业务当前对应的QoS参数集合。终端设备确定该QoS参数集合所属的QoS流为目标业务当前对应的QoS流。
一种具体的实现方式中，如图6所示，SMF可以通过以下S601和S602为终端设备配置业务状态索引规则，以及一个或多个QoS规则。以下进行详细说明：
S601、SMF向终端设备发送第二指示信息。
其中，第二指示信息用于指示多个业务状态索引，与多个QoS参数集合之间的对应关系。
需要指出的是，在S601中，第二指示信息可以直接指示各个业务状态索引与QoS参数集合之间的对应关系，或者第二指示信息也可以指示业务状态索引与上行数据包过滤器集合之间的对应关系，根据上行数据包过滤器集合与QoS参数集合之间的对应关系，间接指示业务状态索引与QoS参数集合之间的对应关系，本申请对此不做限定。

一种可能的实现方式中，在S601之前，还包括：SMF可以多个业务状态索引与多个QoS参数集合之间的对应关系，生成第二指示信息。
S602、SMF向终端设备发送第三指示信息。
第三指示信息用于指示业务状态索引规则。业务状态索引规则用于指示目标业务的多个业务状态索引，与目标业务的多个业务状态的对应关系。
一种可能的实现方式中，业务状态为枚举类型，业务状态索引为整数类型。
例如，工业通信的工业应用的状态的枚举类型为{“稳定”，“不稳定”}，业务状态索引为整数类型{“0”，“1”}，则业务状态索引规则为将业务状态“稳定”映射为业务状态索引“0”，将业务状态索引规则为将业务状态“不稳定”映射为业务状态索引“1”。
又例如，工业通信的工业应用的状态的整数类型{“0”，“1”}，业务状态索引为整数类型{“0”，“1”}，则业务状态索引规则为将业务状态“0”映射为业务状态索引“0”，将业务状态索引规则为将业务状态“1”映射为业务状态索引“1”。

也即是说，该第四指示信息中包括上述一个或多个QoS配置文件。在接入网设备接收到第四指示信息之后，接入网设备可以根据第四指示信息，确定一个或多个QoS配置文件，进而确定第一QoS流的各个QoS参数集合的QoS参数。
一种可能的实现方式中，在S603之前，还包括：SMF根据多个QoS参数集合中， 各个QoS参数集合的QoS参数，生成第四指示信息。

S604、SMF向UPF发送第五指示信息。
第五指示信息用于指示多个业务状态索引，与多个QoS参数集合之间的对应关系。

方式4、接入网设备确定QoS参数集合与DRB的对应关系，并向终端设备配置该对应关系。
其中，一个QoS参数集合对应一个DRB，一个DRB对应一个或多个QoS参数集合。
接入网设备和终端设备可以根据该对应关系，以及目标业务当前的QoS参数集合，确定承载目标业务当前的上行数据的DRB，并在该DRB上传输目标业务当前的上行数据。
一种具体的实现方式中，如图6所示，接入网设备可以通过以下S605确定QoS参数集合与DRB的对应关系，接入网设备可以通过以下S606和S607向终端设备配置QoS参数集合与DRB的对应关系。

在本申请实施例的一种实现方式中，终端设备和UPF需要根据目标业务的业务状态索引，确定目标业务的QoS需求。目标业务的业务状态索引可以通过终端设备确定(记为情况1)，或者可以通过应用服务器确定(记为情况2)。以下分别进行说明：
情况1、终端设备确定目标业务的业务状态索引。
在情况1中，终端设备通过应用层感知目标业务的业务状态。在此之后，终端设备将目标业务的业务状态发送给终端设备的通信层，由终端设备的通信层向UPF发送目标业务的业务状态。

需要指出的是，终端设备通过上行数据的数据包首部发送第一业务状态索引时，终端设备可以在每个上行数据的数据包首部均封装第一业务状态索引，从而使接入网设备可以准确确定每个数据包对应的第一业务状态索引。
或者，终端设备可以仅在目标业务的业务状态发生变化时传输的一个或多个上行数据的数据包首部中封装第一业务状态索引，从而降低第一业务状态索引占用的通信资源。本申请对此不做限定。

需要说明的是，上述UL NG PDU中，可以携带目标业务的上行数据，此时，UL NG PDU称为G-PDU消息，UL NG PDU中，也可以不携带目标业务的上行数据，此时，UL NG PDU称为GTP-U信令消息。

一种可能的实现方式中，应用服务器通过用户面向UPF发送第二业务状态索引。
具体来说，应用服务器将第一业务状态索引封装到应用服务器向UPF发送数据包首部(header)中，将第一业务状态索引与该数据包同步发送给UPF。
一种示例，应用服务器将第二业务状态索引封装在应用服务器向UPF发送的IP数据包首部中。也即是说，应用服务器向UPF发送的IP数据包中包括第二业务状态索引。
S804、UPF向接入网设备发送第二业务状态索引。
其中，S804的具体实现方式与上述S704类似，只需将UL NG PDU相应的替换为下行链路(DownLink，DL)NG PDU即可，本申请对此不再赘述。
S805、接入网设备向终端设备发送第二业务状态索引。
其中，S805的具体实现方式与上述S703类似，本申请对此不再赘述。
需要指出的是，结合上述情况1和情况2，若本申请实施例中仅由应用服务器感知业务状态生成业务状态索引，终端设备无需感知业务状态生成业务状态索引，则SMF 可以不执行上述方式1中所记载的S602，也即是说，SMF无需向终端设备配置业务状态索引规则。
此时，可以由NEF为应用服务器配置业务状态索引规则，应用服务器感知目标业务当前的业务状态之后，根据业务状态索引规则确定目标业务当前的业务状态索引，并分别向终端设备和UPF发送业务状态索引。
一种可能的实现方式中，在上述情况1或情况2之后，终端设备和UPF可以根据目标业务当前的业务状态索引，为目标业务选择相应的DRB和QoS流传输目标业务当前的数据，以下分别结合上述场景1(即上行传输场景)，和场景2(即下行传输场景)进行详细说明：
