5G系统可以采用通用服务质量(Quality of Service，QoS)机制，处理包括XR业务在内的各 类数据服务。5G QoS机制支持有优先级(Priority level)，Priority level用于指示QoS流(flow)间资源分配的优先级。
另外，5G研究引入了分组数据单元集合(Packet Data Unit Set，PDU Set)的QoS处理场景和机制，同时引入了PDU集合重要性(PDU Set Importance)，PDU Set Importance用于指示PDU Set的重要性。
目前，5G系统中存在Priority level和PDU Set Importance两类参数，针对特定业务，例如XR业务的数据流或数据包的资源调度、分配等，由于Priority level针对的是整个QoS流，PDU Set Importance针对的是PDU集合。
本公开提供了一种数据处理方法、装置及存储介质，可以针对不同场景或业务需求的数据丢弃优先级机制进行统一，数据流间与数据流内的优先级机制能够匹配具体需求协同调度。针对特定场景或特定业务，尤其是XR业务的数据传送服务质量QoS和用户体验质量均可以很好地得到支持和保障，完善了QoS流和数据包的资源优先级调度机制，从而可以更好的匹配业务场景，确保业务数据传输的QoS。

其中，第一核心网节点11、第二核心网节点12、控制面节点13、数据面节点14均属于核心网侧功能性节点，相应地，核心网设备10可以包括本公开的第一核心网节点11、第二核心网节点12、控制面节点13、数据面节点14。
核心网设备10可以是一个独立部署的设备，也可以是多个设备组成的设备群，当然，图1仅为示例性说明，实际应用中，核心网设备10还包括其他功能性节点，在此不再一一列举。
图1中还提供了AF节点30，需要说明的是AF节点30不属于核心网节点，AF节点30可以是运营商部署的提供应用服务的功能节点，也可以是来自第三方的提供应用服务的功能节点，本公开对此不作限定。AF节点30一般独立与核心网设备10进行部署。
在本公开实施例中，AF节点30可以将优先级指示信息发送给核心网设备10所包括的第一核心网节点11。
在本公开实施例中，第一核心网节点11可以基于AF节点30提供的信息和/或本地配置信息，确定优先级指示信息后，发送给第二核心网节点12，第二核心网节点12可以通过控制面节点13或数据面节点14将优先级指示信息发送给RAN设备20，RAN设备20可以根据优先级指示信息，执行数据处理，例如执行分组数据单元PDU丢弃。其中，优先级指示信息用于指示PDU丢弃时多类参数的优先级。
还需要说明的是，本公开中的节点可以是实体节点，例如将实体设备作为本公开中的节点，或者本公开中的节点也可以是部署在某个设备上的虚拟节点，本公开对此不作限定。
上述实施例中，可以在网络中存在多类参数的情况下，通过优先级指示信息指示PDU丢弃时多类参数的优先级，第一核心网节点将优先级指示信息发送到RAN设备侧，RAN设备可以根据该优先级指示信息，对应执行PDU丢弃，完善了QoS流和数据包的资源优先级调度机制，从而可以更好的匹配业务场景，确保业务数据传输的QoS。
下面先从第一核心网节点侧介绍一下本公开提供的数据处理方法。
本公开实施例提供了一种数据处理方法，参照图2所示，图2是根据一实施例示出的一种数据处理方法流程图，可以由第一核心网节点执行，第一核心网节点可以包括但不限于PCF节点，该方法可以包括以下步骤：
在步骤201中，确定优先级指示信息。
在本公开实施例中，优先级指示信息用于指示分组数据单元PDU丢弃时多类参数的优先级。
在一个可能的实现方式中，多类参数可以包括但不限于5G系统中执行数据处理时可选的参数。
在一个示例中，多类参数至少可以包括QoS优先级参数和PDU集合重要性参数。
在一个可能的实现方式中，优先级指示信息用于指示在网络拥塞场景下执行PDU丢弃时，多类参数的优先级。
可以理解的是，考虑到不同运营商对网络拥塞场景的条件限定可能不同，该优先级指示信息可以不限于适用于网络拥塞场景，即在非拥塞场景下，第一核心网节点也可以确定优先级指示信息，并发送给RAN设备，由RAN设备基于该优先级指示信息执行PDU丢弃。
还可以理解的是，本公开中将该指示信息称作“优先级指示信息”，由核心网节点向RAN设备提供其他名称的指示信息，以便RAN设备执行数据处理，例如PDU丢弃的方案均应属于本公开的保护范围。
在一个可能的实现方式中，优先级指示信息可以用于指示以下至少一项：PDU丢弃时多类参数的第一优先级顺序；在不同条件下执行PDU丢弃时所述多类参数的第二优先级顺序；PDU丢弃时一类参数所包括的部分参数值相对于其他类参数的第三优先级顺序；每类参数独立适用于流间(cross flows)或流内(inner flow)的PDU丢弃。
在本公开中，优先级指示信息可以用于指示多种优先级顺序，和/或优先级指示信息可以用于指示每类参数独立适用于流间或流内的PDU丢弃，第一核心网节点可以不同的业务配置相应优先级指示信息，配置方式灵活，可用性高。
在一个示例中，当多类参数至少包括QoS优先级参数和PDU集合重要性参数时，该优先级指示信息可以用于指示PDU丢弃时QoS优先级参数和PDU集合重要性参数的第一优先级顺序。
在本公开中，多类参数包括但不限于服务质量QoS优先级参数和PDU集合重要性参数中的至少一项，基于优先级指示信息可以指示QoS优先级参数和PDU集合重要性参数的优先级，完善了QoS流和数据包的资源优先级调度机制，从而可以更好的匹配业务场景，确保业务数据传输的QoS。
示例性地，第一优先级顺序可以为PDU丢弃时QoS优先级参数的优先级高于PDU集合重要性参数的优先级。
即RAN设备在执行PDU丢弃时，优先基于QoS优先级参数执行PDU丢弃。在按照QoS优先级参数执行PDU丢弃后，如果仍不满足停止丢弃PDU的停止丢弃条件，RAN设备可以再基于PDU集合重要性参数执行PDU丢弃。
其中，停止丢弃条件可以包括但不限于以下至少一项：RAN本地决策停止丢弃PDU；网络拥塞程度下降到停止丢弃PDU的预设程度；继续执行PDU丢弃会造成业务无法进行。
RAN设备在执行PDU丢弃过程中只要满足停止丢弃条件中的至少一项，就可以停止执行PDU丢弃。
示例性地，第一优先级顺序可以为PDU丢弃时PDU集合重要性参数的优先级高于QoS优先级参数的优先级。
即RAN侧在执行PDU丢弃时，优先基于PDU集合重要性参数执行PDU丢弃。在按照PDU集合重要性参数执行PDU丢弃后，如果仍不满足停止丢弃PDU的停止丢弃条件，RAN设备可以再基于QoS优先级参数执行PDU丢弃。

例如，当网络拥塞程度为低时，RAN设备在执行PDU丢弃时，优先基于PDU集合重要性参 数执行PDU丢弃。在按照PDU集合重要性参数执行PDU丢弃后，如果仍不满足停止丢弃PDU的停止丢弃条件，RAN设备可以再基于QoS优先级参数执行PDU丢弃。
进一步地，如果按照上述方式执行PDU丢弃后，网络拥塞程度反而上升，例如网络拥塞程度提高到中或者高，则RAN设备切换到优先基于QoS优先级参数执行PDU丢弃。在按照QoS优先级参数执行PDU丢弃后，如果仍不满足停止丢弃PDU的停止丢弃条件，RAN设备可以再基于PDU集合重要性参数执行PDU丢弃。
需要说明的是，以上的条件仅为示例性说明，优先级指示信息用于指示在不同条件下执行PDU丢弃时所述多类参数的不同的第二优先级顺序的方案均应属于本公开的保护范围。
在一个示例中，当多类参数至少包括QoS优先级参数和PDU集合重要性参数时，该优先级指示信息可以用于指示PDU丢弃时，QoS优先级参数和PDU集合重要性参数中的一类参数所包括的部分参数值相对于另一类参数的第三优先级顺序。

或者，第三优先级顺序可以为执行PDU丢弃时，PDU集合重要性参数所包括的部分可选重要性参数值的优先级高于QoS优先级参数的优先级。
例如，QoS优先级参数中包括6个可选QoS优先级参数值，分别为level#1至level#6，第三优先级顺序可以为执行PDU丢弃时，level#5至level#6的优先级高于PDU集合重要性参数的优先级。
即RAN侧在执行PDU丢弃时，优先丢弃对应QoS优先级参数值level#6、level#5的PDU，如果丢弃上述PDU后，仍不满足停止丢弃PDU的停止丢弃条件，RAN设备可以再基于PDU集合重要性参数执行PDU丢弃。如果基于PDU集合重要性参数执行PDU丢弃后，仍然不满足停止丢弃PDU的停止丢弃条件，则RAN设备可以继续丢弃对应QoS优先级参数值level#4、level#3……的PDU。
再例如，PDU集合重要性参数中包括4个可选重要性参数值，分别为1至4，第三优先级顺序可以为执行PDU丢弃时，可选重要性参数值4的优先级高于QoS优先级参数的优先级。

示例性地，当执行流内的PDU丢弃时，RAN设备可以基于所述PDU集合重要性参数确定需要丢弃的PDU集合，且按照PDU集合的重要性由低到高的顺序丢弃对应的PDU集合。
本公开对PDU集合重要性参数的取值大小与重要性高低的关联关系不作限定，即PDU集合重要性取值最小时对应的PDU集合的重要性最高，或者PDU集合重要性取值最大时对应的PDU集合的重要性最高。
例如，当PDU集合重要性取值最小为重要性最高时，RAN设备优先丢弃重要性参数值最大的PDU集合。
假设PDU集合重要性取值为1时指示该PDU集合的重要性最高，取值越大指示该PDU集合的重要性越低，则RAN设备在执行流内的PDU丢弃时，可以最先丢弃重要性参数值最大的PDU集合。

在一个示例中，可以由协议约定优先级指示信息的信息内容与其他关联信息的信息内容之间的对应关系，这里的关联信息可以是第一核心网节点按照协议约定需要发送给RAN设备的信息，RAN设备无需单独接收优先级指示信息，就可以根据上述对应关系和来自第一核心网节点的关联信息的信息内容，确定优先级指示信息的信息内容。
在另一个示例中，第一核心网节点响应于确定所述优先级指示信息用于指示每类参数独立适用于流间或流内的PDU丢弃，可以不发送优先级指示信息给RAN设备。
RAN设备如果未接收到来自第一核心网节点的优先级指示信息，则确定优先级指示信息用于指示每类参数独立适用于流间或流内的PDU丢弃。

在一个可能的实现方式中，优先级指示信息用于指示在网络拥塞场景下执行PDU丢弃时，多类参数的优先级。
可以理解的是，考虑到不同运营商对网络拥塞场景的条件限定可能不同，该优先级指示信息可以不限于适用于网络拥塞场景，即在非拥塞场景下，第一核心网节点也可以确定优先级指示信 息，并发送给RAN设备，由RAN设备基于该优先级指示信息执行PDU丢弃。
还可以理解的是，本公开中将该指示信息称作“优先级指示信息”，由核心网节点向RAN设备提供其他名称的指示信息，以便RAN设备执行数据处理，例如PDU丢弃的方案均应属于本公开的保护范围。
在一个可能的实现方式中，优先级指示信息可以用于指示以下至少一项：PDU丢弃时多类参数的第一优先级顺序；在不同条件下执行PDU丢弃时所述多类参数的第二优先级顺序；PDU丢弃时一类参数所包括的部分参数值相对于其他类参数的第三优先级顺序；每类参数独立适用于流间或流内的PDU丢弃。
在一个示例中，当多类参数至少包括QoS优先级参数和PDU集合重要性参数时，该优先级指示信息可以用于指示PDU丢弃时QoS优先级参数和PDU集合重要性参数的第一优先级顺序。

进一步地，如果按照上述方式执行PDU丢弃后，网络拥塞程度反而上升，例如网络拥塞程度提高到中或者高，则RAN设备切换到优先基于QoS优先级参数执行PDU丢弃。在按照QoS优先级参数执行PDU丢弃后，如果仍不满足停止丢弃PDU的停止丢弃条件，RAN设备可以再基于PDU集合重要性参数执行PDU丢弃。丢弃PDU的实现方式与RAN设备按照第一优先级顺序指定PDU丢弃的过程类似，在此不再赘述。
需要说明的是，以上的条件仅为示例性说明，优先级指示信息用于指示在不同条件下执行PDU丢弃时所述多类参数的不同的第二优先级顺序的方案均应属于本公开的保护范围。
在一个示例中，当多类参数至少包括QoS优先级参数和PDU集合重要性参数时，该优先级指示信息可以用于指示PDU丢弃时，QoS优先级参数和PDU集合重要性参数中的一类参数所包括的部分参数值相对于另一类参数的第三优先级顺序。
相应地，RAN设备可以按照所述第三优先级顺序，依次确定第一参数值，进而依次丢弃与每个所述第一参数值对应的PDU。
示例性地，第三优先级顺序可以为执行PDU丢弃时，QoS优先级参数所包括的部分可选QoS优先级参数值的优先级高于PDU集合重要性参数的优先级。
或者，第三优先级顺序可以为执行PDU丢弃时，PDU集合重要性参数所包括的部分可选重要性参数值的优先级高于QoS优先级参数的优先级。
例如，QoS优先级参数中包括6个可选QoS优先级参数值，分别为level#1至level#6，第三优先级顺序可以为执行PDU丢弃时，level#5至level#6的优先级高于PDU集合重要性参数的优先级。
即RAN侧在执行PDU丢弃时，依次可以将level#6、level#5作为第一参数值，从而优先丢弃对应QoS优先级参数值level#6、level#5的PDU，如果丢弃上述PDU后，仍不满足停止丢弃PDU的停止丢弃条件，RAN设备可以将PDU集合重要性参数所包括的参数值依次确定为第一参数值，执行与第一为参数值对应的PDU丢弃。如果基于PDU集合重要性参数执行PDU丢弃后，仍然不满足停止丢弃PDU的停止丢弃条件，则RAN设备可以继续将QoS优先级参数值level#4、level#3……确定为第一参数值，从而丢弃对应的PDU。
再例如，PDU集合重要性参数中包括4个可选重要性参数值，分别为1至4，第三优先级顺序可以为执行PDU丢弃时，可选重要性参数值4的优先级高于QoS优先级参数的优先级。
即RAN侧在执行PDU丢弃时，先将重要性参数值4确定为第一参数值，进而丢弃重要性参数值4对应的PDU集合，如果丢弃上述PDU集合后，仍不满足停止丢弃条件，RAN设备可以再将QoS优先级参数所包括的参数值确定为第一参数值，执行对应的PDU丢弃。如果基于QoS优先级参数执行PDU丢弃后，仍然不满足停止丢弃条件，则RAN设备可以继续将其他重要性参数值确定为第一参数值，丢弃对应的PDU集合。

本公开对PDU集合重要性参数的取值大小与重要性高低的关联关系不作限定，即PDU集合重要性取值最小时对应的PDU集合的重要性最高，或者PDU集合重要性取值最大时对应的PDU集合的重要性最高。
例如，当PDU集合重要性取值最小为重要性最高时，RAN设备优先丢弃重要性参数值最大的PDU集合。
假设PDU集合重要性取值为1时指示该PDU集合的重要性最高，取值越大指示该PDU集合的重要性越低，则RAN设备在执行流内的PDU丢弃时，可以最先丢弃重要性参数值最大的PDU集合。
即RAN设备按照PDU集合重要性参数值为N、N-1、N-2……的顺序，来丢弃对应的PDU集合。其中，N为大于1的正整数。
再例如，当PDU集合重要性取值最大为重要性最高时，RAN设备优先丢弃重要性参数值最小的PDU集合。
假设PDU集合重要性取值为1时指示该PDU集合的重要性最低，取值越大指示该PDU集合的重要性越高，则RAN设备在执行流内的PDU丢弃时，可以最先丢弃重要性参数值最小的PDU集合。
即RAN设备按照PDU集合重要性参数值为1，2，……N的顺序，来丢弃对应的PDU集合。

如果步骤503和步骤504均执行，则步骤505和步骤506均可以执行。
在步骤507中，RAN设备20基于优先级指示信息，执行分组数据单元PDU丢弃。
步骤507的实现方式与上述步骤401类似，在此不再赘述。
在不矛盾的情况下，本实施方式或实施例中的各步骤及其可选例可以任意组合、任意交换顺序，且本实施方式或实施例及其可选例可以与其他实施方式或实施例及其可选例任意组合。
上述实施例中，可以由第一核心网节点确定优先级指示信息并发送给RAN设备，RAN设备可以基于优先级指示信息，执行分组数据单元PDU丢弃。完善了QoS流和数据包的资源优先级调度机制，从而可以更好的匹配业务场景，确保业务数据传输的QoS。
在一些可选实施例中，本公开提供了优先级指示信息，该优先级指示信息用于指示分组数据单元PDU丢弃时多类参数的优先级，当多类参数至少包括服务质量QoS优先级参数和PDU集合重要性参数时，优先级指示信息用于指示执行PDU丢弃时QoS优先级参数和PDU集合重要性参数的优先级或偏好。
示例性地，优先级指示信息可以由AF提供给第一核心网节点。可选地，AF可以在AF QoS请求过程中将优先级指示信息发送给第一核心网节点。
示例性地，优先级指示信息可以由PCF基于本地配置信息、用户订阅信息、运营商策略等确定。
示例性地，优先级指示信息优先基于AF提供的信息确定。
示例性地，优先级指示信息可以由PCF基于AF提供的信息和PCF本地配置信息共同确定。
即PCF基于AF提供的信息和/或本地配置信息确定优先级指示信息。
优先级指示可以向RAN设备发送(此外，优先级指示包括在要向NG-RAN发送的QoS配置文件中)，以便RAN设备将其用于网络拥塞场景下。
一种方式为，第一核心网节点通过第二核心网节点、控制面节点，在PDU会话修改过程中发送给RAN设备。
另一种方式为，第一核心网节点通过第二核心网节点、数据面节点，发送给RAN设备，其中， 数据面节点可以通过PDU中的用户面报文头将优先级指示信息发送给RAN设备。
在一个可能的实现方式中，优先级指示信息可以用于指示以下至少一项：
PDU丢弃时，PDU集合重要性参数的优先级高于QoS优先级参数的优先级；
PDU丢弃时，QoS优先级参数的优先级高于PDU集合重要性参数的优先级；
在不同条件下执行PDU丢弃时QoS优先级参数、QoS优先级参数的优先级；
PDU丢弃时，PDU集合重要性参数所包括的部分参数值高于QoS优先级参数的优先级；
PDU丢弃时，QoS优先级参数所包括的部分参数PDU集合重要性参数的优先级；
QoS优先级参数独立用于流间的PDU丢弃，PDU集合重要性参数独立用于流内的PDU丢弃。
对于第二核心网节点而言，优先级指示信息可以作为PCC规则的一部分发送到第二核心网节点，第二核心网节点可以将其作为QoS配置文件的一部分发送给RAN设备。
对于RAN设备而言，如果接收到优先级指示信息，可以将其应用于PDU丢弃过程。
当优先级指示信息指示PDU集合重要性参数的优先级高于QoS优先级参数的优先级时，在网络拥塞的情况下，RAN设备可以优先使用PDU集合重要性参数来丢弃对应的PDU集合，在不满足停止丢弃条件时，可以继续使用优先级QoS参数来丢弃QoS流。
当优先级指示信息指示QoS优先级参数的优先级高于PDU集合重要性参数的优先级时，在网络拥塞的情况下，RAN设备可以优先丢弃QoS流，在不满足停止丢弃条件时，可以继续使用PDU集合重要性参数来丢弃对应的PDU集合。
当优先级指示信息指示PDU集合重要性参数基于不同条件(例如网络拥塞程度)优先于QoS优先级参数时，在网络拥塞的情况下，RAN设备可以基于第一条件改变优先级顺序。例如，当网络拥塞程度较低时，使用PDU集合重要性参数丢弃对应的PDU分组，而当拥塞级别为中、高时，切换到使用优先级QoS参数来丢弃QoS流。
当优先级指示信息指示QoS优先级参数独立地用于流间的PDU丢弃，PDU集合重要性参数独立地用于流内的PDU丢弃时，RAN设备将其独立用于以下丢弃：
当一个或多个QoS流不能满足QoS要求时，应使用PDU集合重要性参数来选择对QoS流内的具体PDU集合进行丢弃，从而满足QoS要求。示例性地，当PDU集合重要性参数的最小参数值对应该PDU集合的重要性最高时，PDU集合重要性参数值为N的PDU集合的重要性高于N+1、N+2的PDU集合。
在网络拥塞的情况下，当一个或多个QoS流不能满足所有QoS要求时，应使用QoS优先级参数来选择优先丢弃哪个QoS流。
示例性地，当QoS优先级参数的最小参数值对应该QoS流的重要性最高时，QoS优先级参数值为N的QoS流的优先级高于N+1、N+2的QoS流。RAN设备在执行PDU丢弃时，需要优先丢弃QoS优先级低的QoS流。
此外，RAN设备的调度模块可以基于其他参数(例如资源类型、无线条件)对QoS流进行优先级排序，以优化应用性能和网络容量。
在本公开实施例中，优先级指示信息可以采用显式方式发送给RAN设备，或者采用隐式方式告知RAN设备，例如，当第一核心网节点未向RAN设备发送优先级指示信息时，RAN设备确定优先级指示信息用于指示每类参数独立适用于流间或流内的PDU丢弃。
上述实施例中，完善了QoS流和数据包的资源优先级调度机制，从而可以更好的匹配业务场景，确保业务数据传输的QoS。

步骤602，PCF生成适当的PCC规则信息，其中可以包括与PDU集合相关的QoS参数。PCF向SMF发送PCC规则信息。

其中，PDU集合相关的QoS参数可以为核心网节点中基于PDU集合进行QoS处理的新的QoS参数，还可能包括以下参数：
