Description

相关申请的交叉引用
本公开基于申请号为202211216114.0、申请日为2022年09月30日的中国专利申请提出,并要求该中国专利申请的优先权,该中国专利申请的全部内容在此以引入方式并入本公开。
技术领域
本公开涉及通信技术领域,具体涉及一种数据处理方法、装置、通信设备和存储介质。
背景技术
为了解决在5G网络中识别扩展现实(XR,Extended Reality)数据包的问题,引入了协议数据单元(PDU,Protocol Data Unit)集合(set)的概念。一个数据流可以分成多个PDU set,每个PDU set由多个PDU组成。目前对PDU集合采用一致性处理方式,即如果一个PDU set中的某个数据包丢失,则整个PDU set都应该被丢弃。
这种一致性处理方式具有一些不合理性,首先根据PDU set的定义以及音视频应用的特点,当有些PDU丢失时应用层仍可以恢复全部或部分信息单元,如视频传输中B帧或P帧丢失,应用层仍然可以根据I帧信息进行分析解析,还原视频画面。此外,这种处理还存在着资源浪费的问题,当整个PDU set因为某个PDU的丢失而被丢弃时,该PDU set内已经传输成功的PDU也同时被丢弃,这也是对资源的浪费。因此,网络如何更好的处理PDU集合,目前尚无有效解决方案。

本公开实施例提供了一种数据处理方法。图1为本公开实施例的数据处理方法的流程示意图一;如图1所示,所述方法包括:
步骤101:第一功能在第一PDU集合延迟预算内接收第一PDU集合的PDU。
在一些可选实施例中,所述第一功能是RAN,和/或,用户面功能(UPF,User Plane Function)。其中,RAN也可称为网络设备、通信设备、接入网设备等等。示例性的,RAN可以是通信系统中的基站。
本实施例中,PDU集合(如第一PDU集合,也可记为PDU set)中包括一个或多个PDU。在本公开各实施例中,PDU集合(如第一PDU集合)中的所有PDU的优先级相同。
常规技术方案中,针对PDU通常具有对应的分组时延预算(PDB,Packet Delay Budget),表示分组包可以在UE和UPF之间被延迟的时间的上限。而本申请中,针对PDU集合具有对应的PDU集合延迟预算,可以表示PDU集合(PDU set)可以在UE和UPF之间被延迟的时间的上限。则本实施例中,第一功能在第一PDU集合延迟预算(PDU Set Delay Budget)内接收第一PDU集合的PDU。
本实施例中,第一功能接收的第一PDU集合可以是来自AF的PDU集合。示例性的,PDU集合由AF发出,经过其他核心网网元到达UPF,再由UPF发送至RAN。
在一些可选实施例中,所述PDU包括数据突发包(data burst)和/或数据包(data packet)。对于这里的data packet,为了简化描述,也可以称为data或packet。
在本公开的一些可选实施例中,所述方法还包括:所述第一功能根据在所述第一PDU集合延迟预算内接收到所述第一PDU集合的所有PDU和/或接收携带结束标记的PDU,确定所述第一PDU集合成功传输。
本实施例中,作为一种示例,一个PDU集合的最后一个或多个PDU中会添加结束标记(end marker),第一功能从开始接收第一PDU集合中的 PDU,直到接收到携带结束标记的PDU时,可确定所述第一PDU集合成功传输。作为另一种示例,第一功能也可根据第一PDU集合内的PDU数量,在所述第一PDU集合延迟预算内接收到所述第一PDU集合的所有PDU的情况下,确定所述第一PDU集合成功传输。作为又一种示例,第一功能也可根据第一PDU集合内的PDU数量,在所述第一PDU集合延迟预算内接收到所述第一PDU集合的所有PDU的情况下,也即第一功能接收到携带结束标记的PDU,确定所述第一PDU集合成功传输。
在本公开的另一些可选实施例中,所述方法还包括:所述第一功能根据在所述第一PDU集合延迟预算内接收到的所述第一PDU集合的PDU、第一数值、第二数值、以及接收携带结束标记的PDU中的至少一项信息,确定所述第一PDU集合未成功传输。
可选地,所述第一数值是PDU集合的最大丢失率/数量(Maximum PDU Set Loss Rate/Number),和/或,所述第二数值是PDU集合的内容比率(content ratio)。
本实施例中,第一功能预先获得或确定第一数值和/或第二数值,所述第一数值表示PDU集合的最大丢失率/数量,所述第二数值表示PDU集合的内容比率,进而基于在第一PDU集合延迟预算内已接收到的所述第一PDU集合的PDU和第一数值可确定所述第一PDU集合未成功传输,和/或,基于在第一PDU集合延迟预算内已接收到的所述第一PDU集合的PDU和第二数值,可确定所述第一PDU集合未成功传输,又或者,第一功能可基于第一PDU集合延迟预算内未接收到携带结束标记的PDU可确定所述第一PDU集合未成功传输。
在一些可选实施例中,所述第一功能根据在所述第一PDU集合延迟预算内接收到的所述第一PDU集合的PDU、第一数值、第二数值、以及接收到的携带结束标记的PDU中的至少一项信息,确定所述第一PDU集合未 成功传输,包括以下情况之一:
所述第一功能在所述第一PDU集合延迟预算内丢失的所述第一PDU集合的PDU的数量大于所述第一数值,和/或,未接收到收携带结束标记的PDU,确定所述第一PDU集合未成功传输;
所述第一功能在所述第一PDU集合延迟预算内已接收到的所述第一PDU集合的PDU的数量小于所述第二数值,和/或,未接收到收携带结束标记的PDU,确定所述第一PDU集合未成功传输。
示例性的,作为一种示例,第一功能可以对第一PDU集合延迟预算内已接收到的所述第一PDU集合的PDU的数量和第一数值进行比较,根据比较结果确定第一PDU集合是否成功传输。作为另一种示例,第一功能可以对第一PDU集合延迟预算内已接收到的所述第一PDU集合的PDU的数量和第二数值进行比较,根据比较结果确定第一PDU集合是否成功传输。作为又一种示例,第一功能也可根据第一PDU集合延迟预算内是否接收到携带结束标记的PDU,确定第一PDU集合是否成功传输。其中,接收到携带结束标记的PDU,可确定第一PDU集合成功传输;相应的,未接收到携带结束标记的PDU,可确定第一PDU集合未成功传输。
本实施例中,针对每个PDU集合(如第一PDU集合),该PDU集合下的每个PDU均携带有PDU集合的标识。则第一功能从接收到第一个携带有第一PDU集合的标识的PDU开始统计,统计对应于所述第一PDU集合的、已接收到的PDU的数量。在此过程中可能会出现PDU丢失的情况。则作为一种示例,第一功能对已接收到的所述第一PDU集合的PDU的数量进行统计,确定接收到的PDU数量,从而可确定丢失的PDU数量,进而将丢失的PDU数量与表示最大丢失数量的第一数值进行比较,或者将丢失的PDU数量与第一PDU集合中的PDU的数量进行比较,确定第一PDU集合中的PDU的丢失率,进而将丢失率与表示最大丢失率的第一数值进行 比较;若丢失的PDU数量大于第一数值,或者丢失率大于第一数值,则可表明丢失的PDU较多,确定第一PDU集合未成功传输;若丢失的PDU数量小于或等于第一数值,或者丢失率小于或等于第一数值,则可表明丢失的PDU较少,也可确定第一PDU集合成功传输。作为另一种示例,第一功能对已接收到的所述第一PDU集合的PDU的数量进行统计,确定接收到的PDU数量,进而将PDU数量与第二数值进行比较;若接收到的PDU数量小于第二数值,则可确定第一PDU集合未成功传输;若接收到的PDU数量大于或等于第二数值,也可确定第一PDU集合成功传输。
在本公开的一些可选实施例中,所述方法还包括:所述第一功能确定所述第一PDU集合未成功传输后,执行以下情况中的一种或几种:
所述第一功能丢弃所述第一PDU集合;
所述第一功能丢弃与第一PDU集合有依赖关系(dependency)的其他PDU集合;
所述第一功能根据所述第一PDU集合计算PDU集合误码率(PSER)。
本实施例中,PDU可以是与视频有关的数据包。视频图像通过压缩后,一帧图像或一组图像可压缩为I帧、B帧和P帧,其中,I帧为关键帧,P帧表示的是这一帧跟之前的一个关键帧(或P帧)的差别,B帧是双向差别帧。一个PDU集合中的所有PDU的优先级相同,因此可认为一个PDU集合对应的帧类型是相同的,例如所述第一PDU集合中的所有PDU可以都是I帧数据、B帧数据或P帧数据。以第一PDU集合对应于I帧数据为例,则必然存在其他PDU集合是对应于B帧数据和P帧数据,因此其他PDU集合是与所述第一PDU集合有依赖关系的PDU集合。
本实施例中,PDU集合的依赖关系可以体现在PDU集合组上。例如:PDU可以是与视频有关的数据包,如视频片(slice),此时PDU集合可以是由PDU构成的一个帧,可以是I帧、B帧或P帧。此时,有依赖关系的 几个PDU集合将组成一个PDU集合组,从而构成一个画面组(GOP,Group of Pictures),一般情况下一个GOP为IBBPBBP组成,GOP中的B帧和P帧都对I帧有依赖关系,一个GOP中的B帧和P帧之间也有依赖关系,此时这个PDU集合组中的所有PDU集合之间都有依赖关系,且该PDU集合组中最重要的PDU集合即为I帧,因为其他PDU集合也即该GOP组中的其他B帧P帧都依赖于I帧,这里的I帧也即本公开以下实施例(如权利要求39)中PDU集合组中最重要的PDU集合、即为本实施例中所述的第一PDU集合,若该PDU集合未成功传输或者被丢弃,则该PDU集合组中的其他PDU集合即与第一PDU集合有依赖关系的其他PDU集合也被丢掉。
同理,又例如,当PDU是更小粒度的数据包如视频块(tile)时,此时PDU集合是I-slice或B-slice或P-slice时,PDU集合组是帧,一个PDU集合组内的所有PDU集合都为该帧的视频片,彼此之间也有依赖关系,I slice最为重要,这里的I-slice也即本公开以下实施例(如权利要求39)中PDU集合组中最重要的PDU集合、即为本实施例中所述的第一PDU集合,若该PDU集合未成功传输或者被丢弃,则该PDU集合组中的其他PDU集合即与第一PDU集合有依赖关系的其他PDU集合也被丢掉。
本实施例中,所述第一功能根据所述第一PDU集合计算PSER,从而呈现网络状态。
本公开实施例还提供了一种数据处理方法。图2为本公开实施例的数据处理方法的流程示意图二;如图2所示,所述方法包括:
步骤201:第二功能在一个PDU集合的最后一个或多个PDU中添加结束标记。

本公开实施例还提供了一种数据处理方法。图3为本公开实施例的数据处理方法的流程示意图三;如图3所示,所述方法包括:
步骤301:第一功能接收SMF发送的第一信息。
在一些可选实施例中,所述第一信息是针对PDU集合所在流的所有PDU集合的信息的描述信息,或者简单的说,第一信息为PDU集合的参数(parameter)或PDU集合的特征(PDU set characteristics)。也就是说,所述第一信息包括PDU集合相关的任何信息。
在一些可选实施例中,所述第一功能是RAN,和/或,UPF。
本实施例中,第一功能从核心网(如SMF)接收第一信息。其中,可选地,若第一功能是RAN,则RAN可通过AMF接收SMF发送的第一信息;若第一功能是UPF,则UPF可直接接收SMF发送的第一信息。
在一些可选实施例中,所述第一信息包括以下的至少一项:PDU集合的大小(size)、PDU集合的标识、PDU集合的PDU数量、PDU集合的最大丢失率/数量、PDU集合的延迟预算、PDU集合的内容比率、N3抖动、N9抖动、抖动/抖动范围。
在一些可选实施例中,当PDU集合的标识不同时,所述第一信息中对应所述PDU集合的PDU集合的大小、PDU集合的PDU数量、PDU集合的最大丢失率/数量、PDU集合的延迟预算、PDU集合的内容比率、N3抖动、N9抖动、抖动/抖动范围中的至少一项也不同。
本实施例中,不同的PDU集合,对应的第一信息的内容(除PDU集合的标识以外的其他内容)可相同,也可部分相同部分不同,也可完全不同。
在本公开的一些可选实施例中,所述方法还包括:所述第一功能接收到一个或多个PDU集合的延迟预算;当所述第一功能接收到多个PDU集 合的延迟预算时,所述第一功能根据PDU集合的标识和/或PDU集合的PDU的报文信息(例如,packet相关的信息、或packet中包括的信息、或packet的类型等)选择不同的PDU集合的延迟预算。
在本公开的一些可选实施例中,所述方法还包括:所述第一功能接收到PDU集合的标识时,将为所有携带所述PDU集合的标识的PDU作为整体进行统一处理(例如PDU Set integrated packet handling、或PDU Set integrated packet scheduling、或packets in such a PDU Set are decoded/handled as a whole)。
本实施例中,针对相同PDU集合的标识的PDU,第一功能将采用统一或一致的处理方式。
可选地,所有携带相同PDU集合的标识的PDU具有统一的优先级。或者,携带相同PDU集合的标识的PDU具有相同的优先级。

其中,示例性的,所述针对PDU集合的QoS要求例如可包括针对PDU集合中的所有PDU的时延要求、带宽要求、针对PDU集合的丢包率要求等等。
本实施例中,AF向PCF发送第三信息,所述第三信息为与PDU集合相关的信息,或者也可称为PDU集合信息;PCF基于所述第三信息生成第 二信息,发送所述第二信息至SMF。其中,所述第二信息可包括第三信息中的至少部分内容。

在一些可选实施例中,所述第一信息还包括PDU集合的处理规则。
本实施例中,所述PDU集合的处理规则可以包括以PDU集合为粒度的QoS配置(可记为QoS Profile),即第一功能可对各PDU集合中的所有PDU按照该处理规则(或QoS Profile)进行处理。
本公开实施例还提供了一种数据处理方法。图5为本公开实施例的数据处理方法的流程示意图五;如图5所示,所述方法包括:
步骤501:AF向PCF发送第三信息,所述第三信息包括以下至少一项:PDU集合的标识、PDU集合的大小、PDU集合的PDU数量、PDU集合的最大丢失率/数量、PDU集合的最大丢包率、PDU集合的内容比率、PDU集合的延迟预算、抖动/抖动范围、N6传输抖动、RAN对PDU集合的处理规则、PDU集合处理指示、PDU集合QoS参数、突发周期性、PDU集合头信息、PDU集合依赖信息、PDU集合重要性、PDU集合的QoS要求。

可选地,所述PCF可根据第三信息生成策略信息。示例性的,所述策略信息可以是PCC规则(PCC Rule)。
本公开实施例还提供了一种数据处理方法。图7为本公开实施例的数据处理方法的流程示意图七;如图7所示,所述方法包括:
步骤701:AF从网络功能接收链路MTU数值或数量或大小;
步骤702:AF基于链路MTU数值或数量或大小进行第一处理。
本实施例中,所述网络功能可以是5G系统或5G网络中的网络功能(NF);所述网络功能包括以下其中一种:NEF、UPF、NWDAF、PCF、UDM、UDR、SMF、AMF。
在一些可选实施例中,所述第一处理包括对数据包分片处理,处理后的数据包的大小不超过链路MTU的数值或数量或大小。
本实施例中,AF在对数据或数据包传输之前,基于链路MTU的数值或数量或大小对待传输的数据或数据包进行分片处理,使数据包的大小不超过链路MTU的数值或数量或大小,这样以保证在移动网络中不再对数据或数据包进行分片,提高传输效率,同时对PDU集合的延迟预算以及PDU集合的丢包率都有影响。链路MTU的数值是网络规定的UE和网络每个数 据包中负载payload能传输数据的字节长度,然而应用层面并不遵循该数值来生成数据包,该数值低于应用生成数据包的自己长度,因此如果网络不将链路MTU的数值或数量或大小发送给AF,AF会自己生成数据包,数据包中的字节数会超过该数值。例如链路MTU的数值或数量或大小为1424octets,而AF发送的数据包也即packet也即PDU中相对应的MTU数值为1500octets,AF发送了一个包含20个数据包(PDU)的PDU集合,且规定PDU集合延迟预算为5ms,PDU集合丢包率为10%,那么到网络中由于链路MTU的数值或数量或大小的限制,这20个数据包会被拆分成40个,数量分别为1424,76,1424,76……..1424,76。此时PDU集合的PDU数量翻倍,因此PDU集合传输时延会超出规定的PDU集合延迟预算,同时也会导致PDU集合丢包率变大。而AF如果在传输数据之前知道链路MTU的大小,就会在源头处杜绝此类问题,就会按照1424长度进行发包,不会出现数据传到网络时,被重新分包。因此AF基于链路MTU的数值或数量或大小对待传输的数据或数据包进行分片处理可以有效的减少PDU集合延迟预算,减少第一PDU集合传输不成功的情况,进而降低PDU集合被丢弃的情况,降低PDU集合的丢包率。
需要说明的是,上述属于AF的不同实施例可任意组合。例如AF向PCF发送第三信息后,AF基于链路MTU数值或数量或大小进行第一处理,或者AF向PCF发送第三信息时,AF基于链路MTU数值或数量或大小进行第一处理,或者AF向PCF发送第三信息前,AF基于链路MTU数值或数量或大小进行第一处理,上述示例仅想体现AF的不同实施例的组合,并不限定执行的先后顺序。
本公开实施例还提供了一种数据处理方法。图8为本公开实施例的数据处理方法的流程示意图八;如图8所示,所述方法包括:
步骤801:AF为网络功能提供PDU集合组的第四信息;所述第四信息 包括:属于一个PDU集合的PDU的指示,和/或,属于一个PDU集合组PDU的指示。

本实施例中,所述网络功能可以是5G系统或5G网络中的网络功能 (NF);所述网络功能包括以下其中一种:NEF、UPF、NWDAF、PCF、UDM、UDR、SMF、AMF、AF。
本公开实施例还提供了一种数据处理方法。图10为本公开实施例的数据处理方法的流程示意图十;如图10所示,所述方法包括:

本实施例中,所述网络功能可以是5G系统或5G网络中的网络功能(NF);所述网络功能包括以下其中一种:NEF、UPF、NWDAF、PCF、UDM、UDR、SMF、AMF、AF。
在本公开的一些可选实施例中,所述方法包括:当RAN接收到的PDU集合组中最重要的PDU集合丢失或丢弃时,所述RAN丢弃所述PDU集合组中的其他PDU集合。此处PDU集合组中最重要的PDU集合也即前述实施例中的第一PDU集合,当第一PDU集合未成功传输时,RAN会丢弃所述PDU集合组中的其他PDU集合也即与第一PDU集合有依赖关系的其他PDU集合。
本实施例中,PDU可以是与视频有关的数据包。视频图像通过压缩后,一帧图像或一组图像可压缩为I帧、B帧和P帧,其中,I帧为关键帧,P帧表示的是这一帧跟之前的一个关键帧(或P帧)的差别,B帧是双向差别帧。则一个PDU集合组中可包括与一帧图像或一组图像对应的I帧、B帧和P帧对应的PDU集合。其中,I帧可认为是最重要的帧,也即I帧对应的PDU集合可称为最重要的PDU集合。或者也可认为,所述最重要的PDU集合,是对其他PDU集合来说有依赖关系的PDU集合。则本实施例中,RAN接收到的PDU集合组中最重要的PDU集合丢失或丢弃时,则丢弃PDU集合组中的其他PDU集合。
本实施例中,PDU集合的依赖关系可以体现在PDU集合组上。例如:PDU可以是与视频有关的数据包,如视频片(slice),此时PDU集合可以 是由PDU构成的一个帧,可以是I帧、B帧或P帧。此时,有依赖关系的几个PDU集合将组成一个PDU集合组,从而构成一个画面组GOP,一般情况下一个GOP为IBBPBBP(I表示I帧,B表示B帧,P表示P帧)组成,GOP中的B帧和P帧都对I帧有依赖关系,一个GOP中的B帧和P帧之间也有依赖关系,此时这个PDU集合组中的所有PDU集合之间都有依赖关系,且该PDU集合组中最重要的PDU集合即为I帧,因为其他PDU集合也即该GOP组中的其他B帧P帧都依赖于I帧,这里的I帧也即本公开实施例(如权利要求39中)PDU集合组中最重要的PDU集合即为权利要求1-6中所述的第一PDU集合,若该PDU集合未成功传输或者被丢弃,则该PDU集合组中的其他PDU集合即与第一PDU集合有依赖关系的其他PDU集合也被丢掉。
同理,又例如,当PDU是更小粒度的数据包如视频块(tile)时,此时PDU集合是I-slice或B-slice或P-slice时,PDU集合组是帧,一个PDU集合组内的所有PDU集合都为该帧的视频片,彼此之间也有依赖关系,I slice最为重要,这里的I-slice也即本公开实施例(如权利要求39)中PDU集合组中最重要的PDU集合即为本公开上述实施例(如权利要求1-6)中所述的第一PDU集合,若该PDU集合未成功传输或者被丢弃,则该PDU集合组中的其他PDU集合即与第一PDU集合有依赖关系的其他PDU集合也被丢掉。

在一些可选实施例中,所述第五信息和/或DNN与第一特点的对应关系在UE的签约信息中。
在一些可选实施例中,所述第一功能是RAN和/或UPF,所述第一功能为前文中所述的第一功能,用于在第一PDU集合延迟预算内接收第一PDU集合的PDU。

在一些可选实施例中,所述第一功能是RAN和/或UPF,所述第一功能为前文中所述的第一功能,用于在第一PDU集合延迟预算内接收第一PDU集合的PDU。N3的传输抖动和/或N9的传输抖动可以包含在上述第一信息中。N6传输抖动可以包含在上述第三信息中。
在一些可选实施例中,所述第二功能是以下中的一种:PCF,SMF,AMF,UPF,NWDAF。
