这些高带宽的交互型业务不仅对传输的时效性要求很高，而且随着分辨率、帧率和自由度等指标的提高，应用层产生的数据量极大增长，因此这种业务的应用层生成的数据包内容，需要以很低的时延，切割成大量数据包分段传输，而在分段传输时，如何能够保证数据包得到高效的处理是亟待解决的技术问题。

具体实施方式
现在参考附图以更全面的方式描述示例实施方式。然而，示例的实施方式能够以各种形式实施，且不应被理解为仅限于这些范例；相反，提供这些实施方式的目的是使得本申请更加全面和完整，并将示例实施方式的构思全面地传达给本领域的技术人员。
此外，本申请所描述的特征、结构或特性可以以任何合适的方式结合在一个或更多实施例中。在下面的描述中，有许多具体细节从而可以充分理解本申请的实施例。然而，本领域技术人员应意识到，在实施本申请的技术方案时可以不需用到实施例中的所有细节特征，可以省略一个或更多特定细节，或者可以采用其它的方法、元件、装置、步骤等。
附图中所示的方框图仅仅是功能实体，不一定必须与物理上独立的实体相对应。即，可以采用软件形式来实现这些功能实体，或在一个或多个硬件模块或集成电路中实现这些功能实体，或在不同网络和/或处理器装置和/或微控制器装置中实现这些功能实体。
附图中所示的流程图仅是示例性说明，不是必须包括所有的内容和操作/步骤，也不是必须按所描述的顺序执行。例如，有的操作/步骤还可以分解，而有的操作/步骤可以合并或部分合并，因此实际执行的顺序有可能根据实际情况改变。
需要说明的是：在本文中提及的“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这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
随着5G(5th-Generation，第五代移动通信技术)的发展，使得许多要求多数据量、短时延的多媒体业务得到应用。比如云游戏业务、VR、AR、MR、XR、CR等交互业务。
比如，在图1所示的云游戏场景中，云端服务器101用于运行云游戏，云端服务器101可以对游戏画面进行渲染，并将音频信号及渲染后的图像进行编码处理，最后将编码处理得到的编码数据通过网络传输至各个游戏客户端。游戏客户端可以是具有基本的流媒体播放能力、人机交互能力以及通信能力等的用户设备(User Equipment，用户设备)，例如，智能手机、平板电脑、笔记本电脑、台式计算机、智能电视、智能家居、车载终端、飞行器等；或者该游戏客户端可以是运行于终端设备中的应用程序。具体的，游戏客户端可以将云端服务器101传输的编码数据进行解码，得到模拟音视频信号，并进行播放。
应理解的是，图1中只是示例性的表征云游戏系统的系统架构，并不对云游戏系统的具体架构进行限定；例如在其它实施例中，云游戏系统中还可包括用于调度的后台服务器等等。并且云端服务器101可以是独立的物理服务器，也可以是多个物理服务器构成的服务器集群或者分布式系统，还可以是提供云服务、云数据库、云计算、云函数、云存储、网络服务、云通信、中间件服务、域名服务、安全服务、CDN(Content Delivery Network，内容分发网络)、以及大数据和人工智能平台等基础云计算服务的云服务器。游戏客户端以及云端服务器101可以通过有线或无线通信方式进行直接或间接地连接，本申请在此不做限制。
在上述的各种基于多媒体的交互业务应用场景中，由于多媒体数据包巨大，因此在传输时需要拆分为多个数据包进行传输。具体而言，如图2所示，在5G系统中，用户面主要包括应用服务器、UPF(User Plane Function，用户面功能)、基站(next generation nodeB，简称gNB)和UE(User Equipment，用户设备)。多媒体数据包的传输对于一些典型业务场景主要在下行方向，比如从应用服务器到UPF，然后再通过gNB发送给UE。在进行传输时，多媒体数据包(在图2中以XR数据包为例)在应用服务器的应用层进行拆分，拆分后的数据包作为IP包从应用服务器到达UPF后，5G系统通过PDU(Protocol Data Unit，协议数据单元)会话把子数据包传输到UE端，在UE端从协议栈逐级向上递交并进行重组恢复出该多媒体数据包。
其中，在图2所示的系统中，L1层是指物理层，其用于确保原始的数据可在各种物理媒体上传输；L2层指的是数据链路层，数据链路层在物理层提供的服务的基础上向网络层提供服务；IP(Internet Protocol，网际互联协议)层即为网络层，用于实现两个端系统之间的数据传送；UDP即为User Datagram Protocol，中文名为用户数据报协议；GTP-U即为GPRS(General packet radio service，通用分组无线业务)Tunneling Protocol，中文名为通用分组无线业务隧道协议用户面；PHY即为Physical的简称，中文名为物理层；MAC即为Media Access Control，中文名为媒体访问控制；RLC即为Radio Link Control，中文名为无线链路控制层协议；PDCP即为Packet Data Convergence Protocol，中文名是分组数据汇聚协议；SDAP即为Service Data Adaptation Protocol，中文名是服务数据适配协议。
如前所述，对多媒体业务来说，把一帧多媒体数据包分成多个数据包传输是很常见的情况，但是当这些数据包在网络中进行传输时，网络并不区分这些数据包之间的关联关系，当网络发生拥塞进行丢包时也无法参考这种关联关系。同时，这些数据包是否具备同等重要性，以及部分数据包丢失以后可否恢复等都无法获知，而缺乏这些信息将导致网络侧对 接收到的数据包的处理存在盲目性。正是基于目前所存在的这些问题，本申请的实施例提出了一种新的数据处理方案，使得AF(Application Function，应用功能)可以与核心网网元交互PDU set(即相关联的业务数据包集合)处理相关的参数，直接或者间接影响核心网中相应的策略规则的生成及参数的配置，使得业务数据包能够适应网络资源状态并进行高效的处理。
以下对本申请实施例的技术方案的实现细节进行详细阐述：
图3示出了根据本申请的一个实施例的数据处理方法的流程图，该数据处理方法可以由应用侧网元来执行，应用侧网元即为处于应用层的网元，比如可以是AF。参照图3所示，该数据处理方法可以包括S310至S330，详细介绍如下：
在S310中，检测业务流中的业务数据包之间的关系。
在本申请的实施例中，业务数据包之间的关系用于表示业务流中是否存在具有关联关系的业务数据包，比如一个大数据包切分得到的若干个相关联的子数据包，或者针对同一个业务的多个数据包等。
在一些可选的实施例中，可以根据业务流中的业务数据包所采用的编解码算法来检测业务流中的业务数据包之间的关系，比如一个业务数据包在进行编码或解码时需要依赖于另一个业务数据包，那么说明这两个业务数据包之间存在关联关系。或者一组业务数据包在进行编码时会被添加关联标识，那么说明这组业务数据包具有关联关系，也即是这个业务数据包集合具有关联性，该关联性可以称为数据包关联性。
在一些可选的实施例中，可以根据业务流所对应的业务特性来检测业务流中的业务数据包之间的关系，比如一个业务流对应于一个强交互型业务，那么说明该业务流中可能包含有同一个大数据包切分得到的多个子数据包所形成的业务数据包集合，即该业务数据包集合中的业务数据包存在关联关系。
在一些可选的实施例中，也可以根据业务流中的业务数据包所采用的编解码算法以及业务流所对应的业务特性来检测业务流中的业务数据包之间的关系，比如一个业务流对应于一个强交互型业务(例如经过压缩的图像数据流)，且该业务流中的业务数据包在进行编码或解码时需要依赖于其它业务数据包，那么说明这些业务数据包之间存在关联关系。
在S320中，若检测到业务流中存在具有关联性的业务数据包集合，则生成针对业务数据包集合的指示信息，该指示信息用于指示业务数据包集合所包含的业务数据包的特性。
在一些可选的实施例中，针对业务数据包集合的指示信息用于指示业务数据包集合内的业务数据包具有关联关系，也即是，业务数据包集合具有关联性，并且还可以指示以下至少一种信息：业务数据包集合内的业务数据包是否具有同等重要性、业务数据包集合内的部分业务数据包丢失后是否能够恢复业务数据包集合所对应的内容。
可选地，业务数据包集合内的业务数据包是否具有同等重要性用于表示业务数据包集合内的业务数据包之间的重要性程度。比如，如果业务数据包集合内的业务数据包具有相同的重要性，那么说明这些业务数据包在传输时都不能丢包，如果丢包可能会导致无法恢复出业务数据包集合所对应的内容；如果业务数据包集合内包含的业务数据包的重要性不相同，那么说明这些业务数据包中有些业务数据包是不能丢包的，但是有些业务数据包如果丢包可能也不影响整个业务数据包集合的恢复，进而可以在网络发生拥塞时，丢弃重要性程度较低的业务数据包。
可选地，业务数据包集合内的部分业务数据包丢失后是否能够恢复业务数据包集合所对应的内容用于表示业务数据包集合中哪些数据包是可以在网络发生拥塞时丢弃的业务数据包。
在一些可选的实施例中，针对业务数据包集合的指示信息可以用于指示业务数据包集合内的业务数据包具有关联关系、且业务数据包集合内的业务数据包具有同等重要性。在这种情况下，业务数据包集合内的各个业务数据包在传输时都不能丢包，如果有部分业务 数据包丢包，那么该业务数据包集合内的所有业务数据包都需要丢弃。
在一些可选的实施例中，针对业务数据包集合的指示信息可以用于指示业务数据包集合内的业务数据包具有关联关系、且业务数据包集合内的业务数据包的重要性不相同，并指示业务数据包集合内的部分业务数据包丢失后能够恢复业务数据包集合所对应的内容。在这种情况下，业务数据包集合内的各个业务数据包在传输时，发送端可以识别出各个业务数据包的重要性，并且可以在网络拥塞时丢弃不影响业务数据包集合恢复的部分业务数据包。
在一些可选的实施例中，针对业务数据包集合的指示信息可以用于指示业务数据包集合内的业务数据包具有关联关系、且业务数据包集合内的业务数据包的重要性不相同，并指示业务数据包集合内的部分业务数据包丢失后能够恢复业务数据包集合所对应的内容，并且指示信息还可以指示业务数据包集合的丢包策略，该丢包策略用于指示在网络拥塞时放弃对业务数据包集合内的指定业务数据包的传输。在这种情况下，业务数据包集合内的各个业务数据包在传输时，如果网络发生拥塞，则可以根据丢包策略丢弃业务数据包集合中的指定业务数据包，进而可以在不影响业务数据包集合恢复的前提下，降低网络拥塞带来的影响。
在一些可选的实施例中，也可以通过用户面报头信息来指示业务数据包是否为可丢弃数据包，具体而言，业务数据包集合内的业务数据包还具有用户面报头信息，该用户面报头信息用于指示业务数据包是否为可丢弃数据包。在这种情况下，业务数据包集合内的各个业务数据包在传输时，如果网络发生拥塞，则可以根据业务数据包的用户面报头信息丢弃相应的业务数据包，进而可以在不影响业务数据包集合恢复的前提下，降低网络拥塞带来的影响。
在S330中，将针对业务数据包集合的指示信息发送至核心网网元，以指示核心网网元根据业务数据包的特性对业务数据包集合内的业务数据包进行处理。
在一些可选的实施例中，核心网网元可以是PCF(Policy Control Function，策略控制功能)，应用侧网元(如AF)向PCF发送指示信息时，一种处理方式是应用侧网元直接向PCF发送指示信息，另一种方式是应用侧网元向NEF(Network Exposure Function，网络开放功能)发送指示信息，然后由NEF转发给PCF。
在一些可选的实施例中，如果指示信息指示业务数据包集合内的业务数据包具有关联关系、且业务数据包集合内的业务数据包具有同等重要性，那么核心网网元可以生成对业务数据包集合内的业务数据包进行一体处理的策略信息。比如，若丢弃了业务数据包集合中的一个业务数据包，那么所有的业务数据包都需要丢弃。
在一些可选的实施例中，如果指示信息指示业务数据包集合内的业务数据包具有关联关系、且业务数据包集合内的业务数据包的重要性不相同，那么核心网网元可以生成对业务数据包集合内的业务数据包进行重要性识别及区分处理的策略信息。比如，若网络发生拥塞，那么可以丢弃重要性较低的业务数据包，以在不影响业务数据包集合恢复的前提下，降低网络拥塞带来的影响。
在一些可选的实施例中，还可以对业务数据包集合所包含的业务数据包添加用户面报头信息，该用户面报头信息用于指示业务数据包集合中所包含的各个业务数据包之间的关系，然后将添加了用户面报头信息的业务数据包发送给数据接收端。该实施例的技术方案使得可以通过用户面报头信息来指示业务数据包之间的关系，比如在具有关联性的业务数据包集合中的各个业务数据包中添加关联标识，来表示业务数据包之间的关系。该关联标识比如可以是同一个设定的标识信息，以指示这些业务数据包是相关的，或者该关联标识也可以是业务数据包的序号信息，以指示这些业务数据包之间的顺序关系等。
以上从应用侧网元的角度对本申请实施例的技术方案进行了说明，以下从核心网网元(即PCF)的角度对本申请实施例的技术方案的实现细节作进一步说明：
图4示出了根据本申请的一个实施例的数据处理方法的流程图，该数据处理方法可以由核心网网元来执行，比如可以由PCF来执行。参照图4所示，该数据处理方法可以包括S410至S430，详细介绍如下：
在S410中，接收应用侧网元发送的用于指示业务数据包集合所包含的业务数据包特性的指示信息，该指示信息是应用侧网元在检测到业务流中存在具有关联性的业务数据包集合后发送的。
在一些可选的实施例中，指示业务数据包集合所包含的业务数据包特性的指示信息可以用于指示业务数据包集合内的业务数据包具有关联关系，并且还可以指示以下至少一种信息：业务数据包集合内的业务数据包是否具有同等重要性、业务数据包集合内的部分业务数据包丢失后是否能够恢复业务数据包集合所对应的内容。具体可以参照前述实施例的技术方案，不再赘述。
在S420中，根据指示信息生成针对业务数据包集合的处理策略信息。
在一些可选的实施例中，如果指示信息指示业务数据包集合内的业务数据包具有关联关系、且业务数据包集合内的业务数据包具有同等重要性，那么核心网网元可以生成对业务数据包集合内的业务数据包进行一体处理的策略信息。比如，若丢弃了业务数据包集合中的一个业务数据包，那么集合内所有的业务数据包都需要丢弃。
在一些可选的实施例中，如果指示信息指示业务数据包集合内的业务数据包具有关联关系、且业务数据包集合内的业务数据包的重要性不相同，那么核心网网元可以生成对业务数据包集合内的业务数据包进行重要性识别及区分处理的策略信息。比如，若网络发生拥塞，那么可以丢弃重要性较低的业务数据包，以在不影响业务数据包集合恢复的前提下，降低网络拥塞带来的影响。
在S430中，将处理策略信息发送给会话管理功能实体，以使会话管理功能实体向其它网元配置对业务数据包集合的处理策略。
在一些可选的实施例中，会话管理功能实体SMF(Session Management Function)可以根据接收到的策略信息生成用于反映业务数据包集合内的业务数据包特性的N4规则和无线接入网侧(如NG-RAN，NG-Radio Access Network，新一代无线接入网)的UE上下文，然后将N4规则配置给UPF，将UE上下文配置给基站。可选地，SMF也可以生成用于反映业务数据包集合内的业务数据包特性的UE侧规则，然后将UE侧规则配置给UE。
以上分别从应用侧网元和核心网网元的角度对本申请实施例的技术方案进行了阐述，具体地，本申请实施例的技术方案使得应用侧网元与核心网网元之间可以通过交互实现对具有关联性的业务数据包集合的处理，进而可以保证对业务数据包集合的处理能够适应于网络资源状态，有利于提高业务数据包的处理效率。以下以具体的实施例对本申请实施例的技术方案的实现细节进行再次说明：
在本申请的一个实施例中，应用侧网元可以根据编解码算法及业务特性中的至少一个，得出某个业务流中是否存在数据包关联性，也即是，是否存在具有关联性的业务数据包集合。
比如，一个业务数据包在进行编码或解码时需要依赖于另一个业务数据包，那么说明这两个业务数据包之间存在关联关系。或者一组业务数据包在进行编码时会被添加关联标识，那么说明这组业务数据包具有关联性。再如，一个业务流对应于一个强交互型业务(即业务特性是强交互型业务)，那么说明该业务流中可能包含有同一个大数据包切分得到的多个子数据包所形成的业务数据包集合，即该业务数据包集合中的业务数据包存在关联关系。
如果某个业务流中不存在数据包关联性，也即是，不存在具有关联性的业务数据包集合，那么可以不启动基于关联数据包PDU set的数据包处理机制。
如果某个业务流中存在数据包关联性，也即是，存在具有关联性的业务数据包集合， 则可以指示给5GC控制面网元(如PCF)，5GC控制面网元根据所指示的信息，生成相应的策略和规则，并且配置到各个网元。
可选地，应用侧网元可以包括AF，那么应用侧网元与核心网之间的交互可以通过AF与5GC的控制面交互(针对PDU会话及QoS(Quality of Service，服务质量)流)来实现。在此基础上，应用侧网元还可以包括AS，进而可以通过AS(Application Server，应用服务器)与UPF之间的用户面(针对用户面传输的每个数据包)来实现交互。
可选地，应用侧网元与核心网之间的控制面交互内容包括但不限于：关联数据包PDU set是否存在；如果关联数据包PDU set存在，PDU set内的业务数据包是否具备同等重要性；如果关联数据包PDU set存在，PDU set中的部分业务数据包丢失以后可否恢复PDU set所对应的内容。
基于前述实施例的技术方案，如图5所示，根据本申请的一个实施例的数据处理方法，包括：
S501，应用侧网元指示PDU set特性：PDU set成立、数据包具有同等重要性，即不能部分丢包。
具体地，应用侧网元可以包括AF，AF可以在控制面向PCF提供指示信息(既可以直接将指示信息传递给PCF，也可以先发送给NEF，然后由NEF转发给PCF)。并且应用侧网元也可以包括AS，AS可以提供用户面报头信息来支持PDU set识别，比如用户面报头信息中添加了相应的参数来指示业务数据包集合中所包含的各个业务数据包之间的关系。这种情况下，PDU set内部的数据包都一样重要，如果一个丢弃或者超时，PDU set内部的其余数据包都需要丢弃。
S502，PCF生成相应的策略来支持PDU set处理，如PDU set内的数据包具有同等重要性。
具体地，PCF可以进行映射并生成相应的策略，包括PDU set的识别，PDU set内部数据包的一体化处理策略等。
S503，PCF将生成的策略传递给SMF，生成会话管理策略。
具体地，SMF可以把PCF生成的策略规则进一步处理成给UPF的N4规则，给NG-RAN及UE的SM(Session Management，会话管理)规则，规则中包含了PDU set的识别、PDU set内部数据包的一体化处理策略等。
S504，SMF向UPF配置N4规则，反映PDU set处理。
具体地，SMF与UPF进行交互，把N4规则通过N4接口配置给UPF，该步骤之后，UPF可以和用户面接口上的数据包报头结合来进行PDU set识别及数据包处理。比如根据数据包报头确定数据包是否具有关联性。
S505，配置NG-RAN UE上下文，反映PDU set处理。即SMF配置参数通过AMF传输到NG-RAN，使得基站获取到包括PDU set的识别、PDU set内部数据包的一体化处理策略等。
S506，配置UE侧规则，反映PDU set处理。即SMF配置参数通过AMF传输到UE，使得UE获取到包括PDU set的识别、PDU set内部数据包的一体化处理策略等。
在图5所示的实施例中，AF指示的是PDU Set关联度成立，且数据包具有相同重要性的处理方案。以下结合图6介绍AF指示PDU Set关联度成立，且数据包具有不同重要性的处理方案：
S601，应用侧网元指示PDU set特性：PDU set成立、PDU set内的业务数据包的重要性不同，可以部分丢包，并形成丢包规则。
具体地，应用侧网元可以包括AF，AF可以在控制面向PCF提供指示信息(既可以直接将指示信息传递给PCF，也可以先发送给NEF，然后由NEF转发给PCF)。并且应用侧网元也可以包括AS，AS可以提供用户面报头信息来支持PDU set识别，比如用户面报头 信息中添加了相应的参数来指示业务数据包集合中所包含的各个业务数据包之间的关系。这种情况下，PDU set内部的数据包的重要性不同，丢弃部分业务数据包，不影响PDU set的恢复。
S602，PCF生成相应的策略来支持PDU set处理，如PDU set内的数据包的重要性不同，可以部分丢包，并形成丢包规则。
具体地，PCF可以进行映射并生成相应的策略，包括PDU set的识别、PDU set内部数据包重要性的识别和处理策略。
S603，PCF将生成的策略传递给SMF，生成会话管理策略。
具体地，SMF可以把PCF生成的策略规则进一步处理成给UPF的N4规则，给NG-RAN及UE的SM(Session Management，会话管理)规则，规则中包含了PDU set的识别、PDU set内部数据包重要性的识别和处理策略(如丢包规则)。
S604，SMF向UPF配置N4规则，反映PDU set处理。
具体地，SMF与UPF进行交互，把N4规则通过N4接口配置给UPF，该步骤之后，UPF可以和用户面接口上的数据包报头结合来进行PDU set识别及数据包处理。比如根据数据包报头确定数据包是否具有关联性，并且可以确定哪些数据包是可丢弃数据包。
S605，配置NG-RAN UE上下文，反映PDU set处理。即SMF配置参数通过AMF传输到NG-RAN，使得基站获取到包括PDU set的识别、PDU set内部数据包重要性的识别和处理策略(如丢包规则)等。
S606，配置UE侧规则，反映PDU set处理。即SMF配置参数通过AMF传输到UE，使得UE获取到包括PDU set的识别、PDU set内部数据包重要性的识别和处理策略(如丢包规则)等。同时，也可以反向配置UE上行方向上的传输策略，比如在上行传输方向上的PDU set的识别、PDU set内部数据包重要性的识别和处理策略(如丢包规则)等。
