请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于移动通信技术的通信系统，该无线通信系统可以包括：若干个用户设备110(或称为终端设备110、终端110)以及若干个基站120(或称为接入网设备120)。
其中，用户设备110可以是指向用户提供语音和/或数据连通性的设备。用户设备110可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，用户设备110可以是物联网用户设备，如传感器设备、移动电话和具有物联网用户设备的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程用户设备(remote terminal)、接入用户设备(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment)。或者，用户设备110也可以是无人飞行器的设备。或者，用户设备110也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线用户设备。或者，用户设备110也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站120可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。
其中，基站120可以是4G系统中采用的演进型基站(eNB)。或者，基站120也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站120的具体实现方式不加以限定。
基站120和用户设备110之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，用户设备110之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
这里，上述用户设备可认为是下面实施例的终端设备。
在一些实施例中，上述无线通信系统还可以包含网络管理设备130。
若干个基站120分别与网络管理设备130相连。其中，网络管理设备130可以是无线通信系统中的核心网设备，例如，5G网络的核心网设备，需要说明的是，不同的核心网设备也可以对应不同的网络功能。对于网络管理设备130的实现形态，本公开实施例不做限定。
为了便于本领域内技术人员理解，本公开实施例列举了多个实施方式以对本公开实施例的技术方案进行清晰地说明。当然，本领域内技术人员可以理解，本公开实施例提供的多个实施例，可以被单独执行，也可以与本公开实施例中其他实施例的方法结合后一起被执行，还可以单独或结合后与其他相关技术中的一些方法一起被执行；本公开实施例并不对此作出限定。
为了更好地理解本公开任一个实施例所描述的技术方案，首先，对相关技术中的应用场景进行说明：
移动媒体类服务、云增强现实(AR，Augmented Reality)或者虚拟现实(VR，Virtual Reality)等扩展现实(XR，Extended Reality)业务、云游戏、基于视频的机器或无人机远程控制等业务，预计将为5G网络贡献越来越高的流量。
除了音视频流外，XR业务还涉及多模态数据流，例如，生物触觉感知的数据流。这些多模态数据，是描述同一业务或应用的从同一个设备或不同设备(包括传感器)输入的数据，这些数据可能会输出到一个或多个目的设备终端。多模态数据中的各数据流往往具有一定甚至很强的相关性，例如，音频和视频流的同步，触觉和视觉的同步等。这类媒体业务的数据流本身，各数据流之间，以及这些业务数据流对网络传输的需求，都存在一些共性特征，这些特性的有效识别和利用将更有助于网络和业务的传输、控制，也更有助于业务保障和用户体验。
但是，5G系统采用的是通用QoS机制，处理包括XR业务在内的各类数据服务，没充分考虑到XR媒体业务特性，无法有效地支持差异化的上下行需求，例如，上行数据可靠性和下行数据带宽的非 对称需求。同时，XR媒体数据流具有高带宽、低时延和高可靠性需求的特点，需要进一步匹配数据流内的数据单元和数据集的QoS需求(例如，数据集中数据单元之间的依赖关系、数据集之间的依赖关系、数据集中数据单元的重要性(优先级)和数据集的重要性(优先级)等)，以有效提升用户体验。
同时，高带宽低时延需求的扩展现实和媒体业务(XRM，Extended Reality and Media)业务特性，对无线接入网空口的数据调度和传输提出了新的挑战。5G系统在研究如何基于数据集中数据单元之间的依赖关系和重要性优先级等信息，优化无线接入网空口的数据调度。但当发生网络拥塞时，数据流调度机制依然无法快速缓解拥塞，拥塞过程中数据单元超出QoS时延阈值被丢弃等方式，直接导致业务QoS无法满足，体验质量(QoE，Quality of Experience)降低。相关技术中，5G系统尚不支持XR业务数据流，尤其下行数据流的网络侧调度增强。
如图2所示，本实施例中提供一种数据流的处理方法，其中，所述方法由终端执行，所述方法包括：
步骤21、向第一网络功能发送能力指示信息；
其中，所述能力指示信息用于指示：所述终端支持或者不支持第二网络功能基于预测结果对预定业务的数据流执行预定操作；所述预定操作包括以下至少之一：优化调度；以及流量控制。
这里，本公开所涉及的终端可以是但不限于是手机、可穿戴设备、车载终端、路侧单元(RSU，Road Side Unit)、智能家居终端、工业用传感设备和/或医疗设备等。在一些实施例中，该终端可以是Redcap终端或者预定版本的新空口NR终端(例如，R17的NR终端)。
本公开中涉及的接入网设备可以是基站，所述基站可以为各种类型的基站，例如，第三代移动通信(3G)网络的基站、第四代移动通信(4G)网络的基站、第五代移动通信(5G)网络的基站或其它演进型基站。
本公开中涉及的网络功能可以为核心网中的设备，例如，第一网络功能为会话管理功能(SMF，Session Management Function)或者策略控制功能(PCF，Policy Control Function)；第二网络功能为用户面功能(UPF，User Plane Function)；第三网络功能可以是接入与移动性管理功能(AMF，Access and Mobility Management Function)。当然，所述网络功能也可以是其他演进型网络功能，在此不做限定。
在一个实施例中，所述预定业务为扩展现实和媒体业务XRM或者多模态业务。
在一个实施例中，预测结果可以是预测的在预定时段内需要传输或者是待传输的数据量的大小的结果。需要说明的是，在预测的所述数据量的大小大于设置阈值时，需要执行优化调度和/或流量控制以提升数据流的传输效率，缓解拥塞。当然，在预测的所述数据量的大小小于设置阈值时，也可以不执行优化调度和/或流量控制。
在一个实施例中，所述预测结果可以是网络数据分析功能(NWDAF，Network Data Analytics Function)的预测分析结果。或者，所述预测结果也可以是无线接入网上报的事件通知结果。
在一个实施例中，优化调度可以是优先调度重要等级大于等级阈值的数据流，例如，数据流包括第一数据流和第二数据流，所述第一数据流的重要等级大于所述第二数据流的重要等级，则在网络出现拥塞时，可以优先调度所述第一数据流。当然优化调度也可以包括其他方式，例如，丢弃不重要的数据包和增加传输资源等，在此不做限定。
在一个实施例中，流量控制可以是在网络出现拥塞时控制数据流的流量。示例性地，当拥塞程度大于程度阈值时，减少传输数据流的流量；当拥塞程度小于程度阈值时，增加传输数据流的流量。当然流量控制方式还可以包括其他方式，例如，在拥塞发生时，可以触发主动丢包的操作。
