需要说明的是,图1和图2中的各个网元之间的接口名称只是一个示例,具体实现时接口的名称可能为其它名称,本申请实施例对此不作限定。图1和图2中包括的各个网元(如SMF、PCF、UPF等)的名称也仅是一个示例,对网元本身的功能不构成限定,在5G以及未来其它的网络中,上述各个网元也可以是其它名称,本申请实施例对此也不作限定。示例性地,在6G网络中,上述各个网元中的部分或全部可以沿用5G中的术语,也可能采用其他名称。此外,应理解,上述各个网元之间的所传输的消息(或信令)的名称也仅仅是一个示例,对消息本身的功能不构成任何限定。
在一个示例中,5G网络通过PDU(Protocol Data Unit,协议数据单元)会话提供终端设备到外部数据网络之间的数据传输服务,并可以根据业务的不同,对同一个PDU会话中传输的不同业务数据流提供差异化的QoS(Quality of Service)保障。
请参考图3,其示出了本申请一个实施例提供的QoS模型的示意图。图3所示的QoS模型基于QoS流粒度进行QoS控制。可选地,终端设备通过Uu接口接入5G网络后,在SMF的控制下建立QoS流进行数据传输;SMF向接入网网元提供每个QoS流的QoS流配置信息,包括5QI(5G QoS Identifier,5G QoS标识)、ARP(Allocation and Retention Priority,分配和保留优先权)、以及码率要求等信息。其中,5QI是一个可以对应到例如时延、误码率要求等QoS特征的索引值,例如,5QI的值为66时,对应的时延为100ms(毫秒),对应的误码率为1e-2;ARP为QoS流分配或者保持资源的优先级。对于每个QoS流,接入网网元根据从SMF收到的QoS流配置信息调度无线资源,以对QoS流的QoS要求进行保障。
请参考图4,其示出了本申请一个实施例提供的用户面协议栈的示意图。基于图4所示的用户面协议栈,核心网中的UPF可以解析到数据包的PDU层(PDU layer),例如,对于IP数据包,可以解析到IP数据头(包括源IP地址、目标IP地址、源端口号、目标端口号等信息)。从而,UPF基于解析出的信息确定QoS流,并将业务数据流通过相应的QoS流进行传输,以获得相应的QoS保障。
在一些示例中,终端设备与应用服务器或者对端终端设备之间交互的应用层数据,通常经过特定的编码和压缩等处理,如AR(Augmented Reality,增强现实技术)、VR(Virtual Reality,虚拟现实)、云游戏(Cloud Gaming)等数据。可选地,编码和压缩包括基于H.264等视频编解码技术标准进行的编码和压缩。H.264等视频编解码技术标准通过网络抽象层(Network Abstraction Layer,NAL)格式化数据,并提供应用层数据的头信息。在编码的过程中,部分视频帧序列被压缩成为I帧,部分视频帧序列被压缩成P帧,还有部分视频帧序列被压缩成B帧。其中,I帧是关键帧,属于帧内压缩,解码时只需要本帧数据就可以完成;而P帧和B帧没有完整画面数据,只有与相邻帧的画面差别的数据,解码时需要相邻帧的画面叠加上本帧定义的差别以生成最终画面。
然而,结合图4所示的用户面协议栈,对于经过如压缩编码等处理的视频类业务数据流,网络无法解析应用层数据的数据头,也就无法区分压缩编码后的数据属于I帧还是P帧、B帧,而只能将这些数据视为同一个业务数据流,并进行相同的QoS保障。这样,将无法精确地进行关键帧的重点传输,从而可能导致丢失关键帧的数据,对业务体验有较大影响。
基于此,本申请实施例提供了一种传输方法,能够解决上述技术问题,实现对数据进行应用数据单元级别的控制。如图5所示,为实现本申请提供的传输方法,核心网中的UPF(用户面网元)需要能解析到数据包的应用层(Application layer),例如,需要能读取通过H.264等视频编解码技术进行编码和压缩的NAL格式化的数据。下面,结合几个实施例对本申请提供的传输方法进行介绍说明。
请参考图6,其示出了本申请一个实施例提供的传输方法的流程图。该方法可以应用于上述图1和图2所示的系统架构中,并且,该方法可以上述图3所示的QoS模型和图5所示的用户面协议栈为基础。该方法可以包括如下步骤中的至少部分步骤。

本申请实施例中,策略控制网元在接收到来自于应用功能的第一识别信息之后,可以向会话管理网元发送第一识别信息和第一控制信息。有关第一识别信息的内容和发送方式的介绍说明,请参见上述实施例和下述实施例,此处不多赘述。其中,第一控制信息用于指示应用数据单元的控制参数,也就是说,第一控制信息与业务数据流中的应用数据单元对应。可选地,第一控制信息包括但不限于以下至少一项:第二等级信息、第二参数信息等。第二等级信息用于指示应用数据单元的等级,可选地,第二等级信息包括但不限于以下任意一项:应用数据单元在应用层的重要性等级、应用数据单元是否允许跳过或丢弃等。第二参数信息用于指示应用数据单元的QoS参数,可选地,第二参数信息包括但不限于以下至少一项:QoS等级标识、传输层优先级、误码率、传输时延、码率要求等。
需要说明的一点是,第一控制信息是指策略控制网元所确定的应用数据单元的控制参数,而上述第一需求信息是指应用功能所需求的应用数据单元的控制需求。在应用功能向策略控制网元发送第一需求信息的情况下,策略控制网元可以结合第一需求信息确定第一控制信息,也可以在第一控制信息的确定过程中忽视第一需求信息,本申请实施例对此不作限定。以策略控制网元结合第一需求信息确定第一控制信息为例,假设第一需求信息包括第一等级信息和第一参数信息、第一控制信息包括第二等级信息和第二参数信息,策略控制网元可以直接将第一等级信息作为第二等级信息,和/或,将第一参数信息作为第二参数信息;或者,策略控制网元可以结合第一参数信息重新确定第二参数信息,例如,第一参数信息包括应用功能需求的误码率,策略控制网元可以将第二参数信息中的误码率,设置为小于第一参数信息中的误码率。

步骤650,会话管理网元向接入网网元发送第三控制信息。
会话管理网元在接收到来自于策略控制网元的第一控制信息之后,可以向接入网网元发送第三控制信息。由于接入网网元无法识别到业务数据流粒度,因而会话管理网元可以确定业务数据流对应的QoS流,并确定QoS流中的应用数据单元的控制参数,进而,会话管理网元向接入网网元发送的是第三控制信息,该第三控制信息即用于指示QoS流中的应用数据单元的控制参数,也就是说,第三控制信息与QoS流中的应用数据单元对应。可选地,第三控制信息包括但不限于以下至少一项:第三等级信息、第三参数信息等。第三等级信息用于指示应用数据单元的等级,可选地,第三等级信息包括但不限于以下任意一项:应用数据单元在应用层的重要性等级、应用数据单元是否允许跳过或丢弃等。第三参数信息用于指示应用数据单元的QoS参数,可选地,第三参数信息包括但不限于以下至少一项:QoS等级标识、传输层优先级、误码率、传输时延、码率要求等。有关第三控制信息的确定过程等其它介绍说明,请参见下述方法实施例,此处不多赘述。

下面,针对第一识别信息在业务数据流过滤器中的情况下,图6实施例中各个步骤的执行主体所执行的操作等进行介绍说明。
请参考图7,其示出了本申请一个实施例提供的传输方法的流程图。该方法可以应用于上述图1和图2所示的系统架构中,并且,该方法可以上述图3所示的QoS模型和图5所示的用户面协议栈为基础。该方法可以包括如下步骤中的至少部分步骤。

步骤631,会话管理网元基于第一控制信息,确定传输业务数据流的QoS流和第三控制信息,第三控制信息用于指示QoS流中的应用数据单元的控制参数。
由于在图7实施例中,业务数据流过滤器仅能匹配业务数据流中的应用数据单元,从而对于业务数据流的QoS保障,也仅需考虑应用数据单元的控制参数即可。基于此,会话管理网元在接收到来自于策略控制网元的第一控制信息之后,基于第一控制信息确定传输业务数据流的QoS流,例如,对于具有不同控制参数的应用数据单元所在的业务数据流,采用不同的QoS流传输。
此外,会话管理网元还需要结合第一控制信息确定第三控制信息,以便于后续向接入网网元指示QoS流中的应用数据单元的控制参数。可选地,在第一控制信息包括第二等级信息和第二参数信息、第三控制信息包括第三等级信息和第三参数信息的情况下,会话管理网元可以直接将第二等级信息作为第三等级信息,且结合第二参数信息确定第三参数信息,例如,第三参数信息中的误码率为至少一个第二参数信息中的误码率之和,第三参数信息中的码率为至少一个第二参数信息中的码率之和,等等。其中,至少一个第二参数信息用于指示:聚合到同一个QoS流的业务数据流中的应用数据单元的控制参数。

步骤652,会话管理网元向接入网网元发送第三控制信息。
会话管理网元在接收到来自于策略控制网元的第一控制信息之后,还可以向接入网网元发送步骤631中,会话管理网元基于第一控制信息确定的第三控制信息。其中,第三控制信息与QoS流中的应用数据单元对应。在一个示例中,如图7所示,上述步骤652还包括:会话管理网元向接入网网元发送QoS流标识,该QoS流标识用于标识传输业务数据流的QoS流。
综上所述,本申请实施例提供的技术方案,通过将用于识别应用数据单元的识别信息添加在业务数据流过滤器中,使得业务数据流过滤器能够匹配应用数据单元中的数据包,从而,本申请实施例提供的应用数据单元级别的传输控制,能够兼容业务数据流级别的传输控制的消息设计等。
下面,针对第一识别信息在业务数据流过滤器外的情况下,图6实施例中各个步骤的执行主体所执行的操作等进行介绍说明。
请参考图8,其示出了本申请一个实施例提供的传输方法的流程图。该方法可以应用于上述图1和图2所示的系统架构中,并且,该方法可以上述图3所示的QoS模型和图5所示的用户面协议栈为基础。该方法可以包括如下步骤中的至少部分步骤。
在图8实施例中,上述步骤610实现为下述步骤614、上述步骤620实现为下述步骤624、上述步骤630之前还包括下述步骤633、上述步骤630实现为下述步骤634、上述步骤640实现为下述步骤644、上述步骤650实现为下述步骤654。
步骤614,应用功能向策略控制网元发送第一识别信息和业务数据流过滤器。
第一识别信息可以独立于业务数据流过滤器,从而,业务数据流所包括的数据包中,不仅应用数据单元中的数据包能够与业务数据流过滤器匹配,还有不属于任何应用数据单元的数据包也能够与业务数据流过滤器相匹配,也就是说,业务数据流过滤器用于匹配业务数据流(包括业务数据流中的应用数据单元中的数据包,也包括业务数据流中不属于任何应用数据单元的数据包)。
基于此,应用功能向策略控制网元发送第一识别信息和业务数据流过滤器。在一个示例中,如图8所示,上述步骤614还包括:应用功能向策略控制网元发送第一需求信息,该第一需求信息用于指示应用数据单元的控制需求。在一个示例中,如图8所示,上述步骤614还包括:应用功能向策略控制网元发送第二需求信息,该第二需求信息用于指示应用功能针对业务数据流的QoS需求。其中,第二需求信息与业务数据流对应,第一需求信息与业务数据流中的应用数据单元对应。有关步骤614中未详细地介绍说明的内容,如第一识别信息的内容、第一需求信息的内容、业务数据流过滤器的内容等,请参见上述步骤610中的介绍说明,此处不多赘述。

由于在图8实施例中,业务数据流过滤器不仅能匹配业务数据流中的应用数据单元中的数据包,还能匹配到业务数据流中不属于任何应用数据单元的数据包,从而对于业务数据流的QoS保障,不仅需考虑应用数据单元的控制参数,还需要考虑业务数据流的QoS参数。基于此,会话管理网元在接收到来自于策略控制网元的第一控制信息和第二控制信息之后,基于第二控制信息确定传输业务数据流的QoS流,例如,对于具有不同控制参数的业务数据流采用不同的QoS流传输、对于具有相同控制参数的业务数据流采用相同的QoS流传输。应理解,图8实施例中,会话管理网元在确定传输业务数据流的QoS流的过程中,无需考虑数据包是否属于应用数据单元。
此外,会话管理网元还需要结合第二控制信息确定第四控制信息,以便于后续向接入网网元指示QoS流的QoS参数。例如,会话管理网元将第二控制信息中的码率之和作为第四控制信息中的码率,将第二控制信息中的误码率之和作为第四控制信息中的误码率,等等。并且,会话管理网元还需要结合第一控制信息确定第三控制信息,以便于后续向接入网网元指示QoS流中的应用数据单元的控制参数。
有关步骤631中未详细地介绍说明的内容,如第三控制信息的内容、第三控制信息的确定方式等,请参见上述步骤650和上述步骤631中的介绍说明,此处不多赘述。

步骤654,会话管理网元向接入网网元发送第四控制信息和第三控制信息。
会话管理网元在接收到来自于策略控制网元的第一控制信息和第二控制信息之后,还可以向接入网网元发送步骤633中,会话管理网元基于第二控制信息确定的第四控制信息,以及基于第一控制信息确定的第三控制信息。其中,第四控制信息与QoS流对应,第三控制信息与QoS流中的应用数据单元对应。在一个示例中,如图8所示,上述步骤654还包括:会话管理网元向接入网网元发送QoS流标识,该QoS流标识用于标识传输业务数据流的QoS流。为了使得接入网网元能够识别应用数据单元,以实现对应用数据单元中的数据包进行不同于业务数据流中的其它数据包的QoS保障,在一个示例中,如图8所示,上述步骤654还包括:会话管理网元向接入网网元发送第一识别信息。
综上所述,本申请实施例提供的技术方案,通过将用于识别应用数据单元的识别信息作为独立于业务数据流过滤器的信息,使得业务数据流过滤器不仅能够匹配应用数据单元中的数据包,还能够匹配业务数据流中不属于任何应用数据单元的数据包,实现了在对业务数据流进行整体的QoS保障的基础上,对业务数据流中的应用数据单元进行针对性的QoS保障。
在上述图8实施例的基础上,会话管理网元在上述步骤633中还可以基于第一识别信息确定应用数据 单元的编号。下面,对这一方式进行介绍说明。
请参考图9,其示出了本申请一个实施例提供的传输方法的流程图。该方法可以应用于上述图1和图2所示的系统架构中,并且,该方法可以上述图3所示的QoS模型和图5所示的用户面协议栈为基础。该方法可以包括如下步骤中的至少部分步骤。

在图9实施例中,会话管理网元对应用数据单元重新进行了编号,会话管理网元结合第一识别信息和/或业务数据流过滤器,确定应用数据单元的编号。示例性地,会话管理网元将业务数据流过滤器A中标识为1的应用数据单元,重新编号为A1(也即这些应用数据单元的编号为A1);将业务数据流过滤器B中标识为1的应用数据单元,重新编号为B1(也即这些应用数据单元的编号为B1)。有关步骤635中未详细地介绍说明的内容,如第四控制信息的确定过程、第三控制信息的确定过程等的介绍说明,请参见上述图8实施例中步骤633的介绍说明,此处不多赘述。
步骤636,会话管理网元向终端设备发送应用数据单元的编号。
会话管理网元在重新确定了应用数据单元的编号之后,可以向终端设备发送应用数据单元的编号。在一个示例中,如图9所示,上述步骤636还包括:会话管理网元向终端设备发送第一识别信息、业务数据流过滤器和QoS流标识。
