具体实施方式
下文中将结合附图对本申请的实施例进行说明。以下结合实施例附图对本申请进行描述，所举实例仅用于解释本申请，并非用于限定本申请的范围。
如何识别用户面数据包(IP packets)与应用层数据包的关联关系，应用层数据包之间的关联关系，以及映射到同一QoS Flow的应用层数据包之间的不同优先级，是一个亟待解决的问题。
在NR网络中，业务的QoS参数是核心网通过控制面信令向基站配置的，是按照PDU Session--->QoS flow级别配置的。一个用户设备(User Equipment，UE)可以最多建立256个PDU Session，一个PDU Session可以最多包含64个QoS flow，而QoS参数是按QoS flow进行配置的。QoS参数包括：用户优先级信息(分配保留优先级(Allocation and Retention Priority，ARP))、保证比特速率(Guaranteed Bit Rate，GBR)信息(GBR QoS flow information)、第5代移动通信技术业务服务质量标识(5th Generation Mobile Communication Technology Quality of Service Identifier，5QI)描述信息(业务类型对应的5QI索引、业务优先级Priority、业务最大延迟(Packet Delay Budget，PDB)等)。
对于下行业务，每个用户面的PDU在对应的PDU通道(通用分组无线服务技术通道协议用户面通道(General Packet Radio Service Tunnelling Protocol–User Tunnel，GTP-U Tunnel))上传输，且在PDU的扩展头(extension header，也就是新空口无线接入网容器(New Radio Radio Access Network Container，NR RAN Container)或PDU Session Container)中携带服务质量流标识(Quality of Service Flow Identifier，QFI)指示，从而将PDU与QoS参数相关联，做到了 QoS Flow级别的PDU调度优先级区分。
对于上行业务，用户面的PDU与QoS Flow关联，基站可以将不同Qos flow映射到不同数据无线承载(Data Radio Bearer，DRB)上，不同DRB对应不同的LCG。UE在BSR请求中携带逻辑信道组标识(Logical Channel Group Identifier，LCG ID)，基站基于BSR信息分配上行调度资源，从而实现了QoS Flow级别的PDU调度优先级区分。
一个QoS flow只有一个QoS优先级，且不同QoS Flow的数据包之间没有关联关系。但是在XR等业务中，不同PDU可能优先级不同，但PDU之间有依赖关系，比如一个视频序列有多个I-frame，P-frame和B-frame，其中P-frame和B-frame的解码依赖于I-famre；而每个frame又由多个IP packets(PDU)组成。图1是一实施例提供的一种应用层数据单元、应用层数据包和IP包之间的配置关系图。如图1所示，一个应用层数据单元(视频编码单元)由12个视频帧(即应用层数据包/应用层数据帧)构成，12个视频帧包括I 1B 2B 3P 4B 5B 6P 7B 8B 9P 10B 11B 12(I帧(I 13)出现表示一个新的应用层数据单元开始)，每个视频帧又由多个IP包(即用户面数据包或PDU)构成(I 1帧由n个IP包I 11I 12...I 1n组成；B 2由m个IP包B 21B 22...B 2m组成...)。其中，IP数据包也可以是用户数据包协议(User Datagram Protocol，UDP)数据包或者以太网数据包。
图2是一实施例提供的一种PDU会话的帧格式的配置示意图。在实施例中，核心网向基站发送如图2所示的PDU会话的帧格式，PDU SESSION的帧格式是携带在GTP-U PDU的扩展头(extension header，也就是NR RAN Container或PDU Session Container)里，放在GTP-U Tunnel上传输的。
基站从该PDU SESSION的帧格式可以看出：PDU对应的QoS Flow Identifier和下行链路业务服务质量流标识序号(Down Link Quality of Service Flow Identifier Sequence Number，DL QFI Sequence Number)；基站基于S1应用协议(S1 Application Protocol，S1AP)接口的信令和NG应用协议(NG Application Protocol，NGAP)接口的信令可以知道QoS Flow Identifier对应的Priority Level。
但是基站无法识别IP packets(即用户面数据包)与应用层数据包(也可以称为应用层数据帧)的关联关系、应用层数据帧之间的关联关系，以及映射到同一QoS Flow的应用层数据帧之间的不同优先级。因此，如何对PDU SESSION的帧格式进行增强，是一个亟待解决的问题。
在一实施例中，图3是本申请实施例提供的一种参数配置方法的流程图。本实施例可以由第一通信节点执行。其中，第一通信节点为基站。如图3所示， 本实施例包括：S310-S320。

在实施例中，QoS流的子流标识指的是QoS流中所包含的每个QoS子流的标识；QoS流的子优先级指的是QoS流中所包含的每个QoS子流的优先级。在一实施例中，QoS流的子流标识和QoS流的子优先级可以采用QoS流子优先级表示，即QoS流子优先级中既包含QoS子流的标识，也包含QoS子流的优先级。
S320、根据PDU会话的帧格式确定同一QoS流中不同用户面数据包的调度优先级或资源分配权重。
在实施例中，第二通信节点通过用户面向第一通信节点发送PDU会话的帧格式，并且在PDU会话的帧格式中包含应用层数据包识别信息，ADU识别信息，QoS流的子流标识以及QoS流的子优先级中的至少之一，以使第一通信节点根据PDU会话的帧格式识别用户面数据包与应用层数据包的关联关系、不同应用层数据包之间的关联关系，以及映射到同一QoS流的应用层数据包之间的不同优先级，从而第一通信节点可以按照该PDU会话的帧格式确定同一QoS流中不同用户面数据包的调度优先级或资源分配权重，从而可以按照调度优先级和分配的调度资源进行BSR的上报。

在一实施例中，不同优先级的应用层数据包映射到同一个QoS流；PDU会话的帧格式至少包括：ADU识别信息。在实施例中，在不同优先级的应用层数据包映射到同一个QoS流中时，可以在PDU会话的帧格式中携带ADU识别信息，以指示每个应用层数据包所对应的应用层数据单元的开始传输指示和结束传输指示，进而可以确定应用层数据单元内每个应用层数据包的优先级。其中，ADU识别信息隐含指示每个ADU内应用层数据包越靠前优先级越高。在一实施例中，ADU识别信息的指示位可以为一个比特(bit)，也可以为两个bit。
在一实施例中，采用ADU识别信息指示至少两个级别的应用层数据单元。在实施例中，可以对ADU识别信息中所携带的参数进行组合、复用和多级包含，以指示多个级别的应用层数据单元。示例性地，假设采用ADU识别信息指示两个级别的应用层数据单元，一级应用层数据单元可以为一个视频流，二级应用 层数据单元可以为一个视频帧。
在一实施例中，ADU识别信息至少包括下述之一：应用层数据单元的开始传输指示；应用层数据单元的结束传输指示。在实施例中，应用层数据单元的开始传输指示，用于指示同一个应用层数据单元中的第一个应用层数据包所在的位置；应用层数据单元的结束传输指示，用于指示同一个应用层数据单元中的最后一个应用层数据包所在的位置。

在一实施例中，不同QoS优先级的应用层数据包映射到不同的QoS流；PDU会话的帧格式包括下述之一：关联的QoS流标识QFI和关联的下行QFI序号。
所述关联的QoS流标识QFI和关联的下行QFI序号用于表征本PDU会话帧与所述关联的QoS流标识QFI和关联的下行QFI序号之间存在关联关系、依赖关系、补充关系、主辅关系、从属关系或者时序关系。
在一实施例中，PDU会话的帧格式包括下述之一：应用层数据单元中可容忍的最大丢包总数；应用层数据单元中可容忍的最大连续丢包总数。所述丢包总数为丢失的用户面数据包总数或丢失的应用层数据包总数。在实施例中，第二通信节点可以通过用户面向第一通信节点发送PDU会话的帧格式，并在PDU会话的帧格式中携带应用层数据单元中可容忍的最大丢包总数，或者应用层数据单元中可容忍的最大连续丢包总数。所述丢包总数为丢失的用户面数据包总数或丢失的应用层数据包总数。
在一实施例中，PDU会话的帧格式还包括：应用层数据单元的开始传输指示；应用层数据单元所包含的用户面数据包总数量。在实施例中，应用层数据单元所包含的用户面数据包总数量指的是一个应用层数据单元中一共所包含的用户面数据包数量，即IP包数量，也可以称为PDU数量。
在一实施例中，应用层数据包识别信息中也可以包括：应用层数据包序号、 应用层数据包的开始传输指示、应用层数据包的结束传输指示、应用层数据包所包含的用户面数据包总数量中的至少两个。对应用层数据包识别信息中的每个参数的解释同ADU识别信息中对应参数的解释，只是将应用层数据单元更换为应用层数据包。
在一实施例中，不同优先级的应用层数据包映射到同一QoS流；将同一QoS流中不同的子流标识或子优先级映射到不同专用无线承载DRB标识、不同逻辑信道(Logical Channel，LC)标识、或不同的逻辑信道组LCG标识上。在实施例中，第一通信节点将同一QoS流中不同的子流标识或子优先级映射到不同LC标识上，再将不同LC标识映射到不同LCG标识上，进而可以实现将同一QoS流中具有不同优先级的QoS子流或子优先级映射到不同LCG标识上。在实施例中，在不同优先级的应用层数据包映射到同一QoS流的情况下，第一通信节点可以将同一QoS流中不同的子流标识或子优先级映射到不同DRB标识、不同LC标识、或不同的LCG标识上，以使第三通信节点按照不同的子流标识或子优先级进行BSR上报。
在一实施例中，将同一QoS流中不同的子流标识或子优先级映射到不同DRB标识、不同LC标识、或不同的LCG标识上，包括：QoS流的子流标识或QoS流的子优先级包含在发送给第三通信节点的以下至少之一的配置信息中：服务数据适配协议SDAP配置信息，无线承载配置信息，逻辑信道配置信息、无线链路控制配置信息。

在一实施例中，QoS流的子流标识或QoS流的子优先级用于将同一QoS流的用户面数据包映射到不同的逻辑信道上。在实施例中，第一通信节点将同一QoS流中不同的子流标识或子优先级映射到不同LC标识上，再将不同LC标识 映射到不同LCG标识上，进而可以实现将同一QoS流中具有不同优先级的QoS子流或子优先级映射到不同LCG标识上。第三通信节点基于LCG标识进行BSR请求时，第一通信节点可以对同一QoS流中具有不同优先级的QoS子流或子优先级进行BSR区分。
在此需要说明的是，应用于第三通信节点的参数配置方法中对每个参数的解释，可参见上述实施例中应用于第一通信节点的参数配置方法中对应参数的描述，在此不再一一赘述。
在一实施例中，图5是本申请实施例提供的又一种参数配置方法的流程图。本实施例可以由第二通信节点执行。其中，第二通信节点为核心网。如图5所示，本实施例包括：S510。

在一实施例中，不同优先级的应用层数据包映射到同一个QoS流；PDU会话的帧格式至少包括下述之一：ADU识别信息。
在一实施例中，采用ADU识别信息指示至少两个级别的应用层数据单元。
在一实施例中，ADU识别信息至少包括下述之一：应用层数据单元的开始传输指示；应用层数据单元的结束传输指示。

所述关联的QoS流标识QFI和关联的下行QFI序号用于表征本PDU会话帧与所述关联的QoS流标识QFI和关联的下行QFI序号之间存在存在关联关系、依赖关系、补充关系、主辅关系、从属关系或者时序关系。

QoS流的子流标识或QoS流的子优先级用于将同一QoS流的用户面数据包映射到不同的逻辑信道上。
在此需要说明的是，应用于第二通信节点的参数配置方法中对每个参数的解释，可参见上述实施例中应用于第一通信节点的参数配置方法中对应参数的描述，在此不再一一赘述。
在一实施例中，不同优先级的应用层数据包映射到同一QoS Flow，在PDU会话的帧格式内引入应用层数据包识别信息或优先级指示。其中，应用层数据识别信息为应用层数据包类型(Application packet Type)。以第一通信节点为基站为例，图6是本申请实施例提供的另一种PDU会话的帧格式的配置示意图。如图6所示，PDU SESSION的帧格式中携带如下至少之一：应用层数据包类型、应用层数据包的子优先级(Application packet sub-Priority)、应用层数据包的子流标识(Application packet sub-Flow ID)。其中，应用层数据包类型(Application packet Type)或应用层数据包的优先级(Application packet Priority)用于基站识别PDU(即上述实施例中的用户面数据包，或IP Packets)在传输过程中的重要 程度，从而识别出同一QoS flow下不同PDU的调度优先级或资源分配的权重。
基于应用层数据包类型，基站可以判断PDU对应的应用层数据包类型，从而决定该PDU的调度优先级、可靠性要求高低或资源分配的权重；应用层数据包类型可以指示该IP包对应的应用层数据包类型，比如：指示视频流里I帧数据包、B帧数据包、以及P帧数据包；或者指示数据包是主包还是次包，用于基站识别数据包的主要程度。
基于应用层数据包的子优先级或应用层数据包的子流信息，基站可以判断PDU对应的应用层数据包的优先级，从而决定该PDU的调度优先级、可靠性要求或资源分配的权重。
核心网到基站的S1AP/NGAP信令里的QoS flow里包含的应用层数据包的子优先级(Application packet sub-Priority)和/或应用层数据包的子流标识(Application packet sub-Flow ID)用于基站为同一QoS flow下不同sub-Priority的数据包配置不同优先级的资源。图7是本申请实施例提供的一种QoS流中增加QoS子流的配置示意图；图8是本申请实施例提供的另一种QoS流中增加QoS子流的配置示意图。如图7所示，每个QoS Flow下包含多个QoS sub-flow，每个QoS sub-Flow包含：QoS流的子流标识(QoS sub-flow ID)和QoS流的子优先级(QoS sub-flow Priority)；或者，每个QoS sub-Flow包含QoS流子优先级(QoS sub-Priority)。QoS Flow里的QoS sub-flow也可以不体现，只体现：QoS flow下包含多个QoS sub-Priority，如图8所示，PDU会话的帧格式中也只包含QoS sub-Priority(即图6中)；如果QoS Flow里体现了QoS sub-flow，则PDU Format里也包含QoS sub-flow ID和QoS sub-flow Priority；或者，PDU Format里包含QoS sub-Priority。
QoS sub-flow相关的QoS参数可以基于QoS Flow的QoS参数差分定义，比如：QoS sub-flow相关的QOS参数中只包含与QoS Flow的QoS参数里取值不同的参数。
对于QoS优先级：基站基于QoS flow的优先级和QoS sub-flow的优先级映射逻辑信道优先级。比如QoS的绝对优先级＝QoS flow的优先级+QoS sub-flow的优先级。
在一实施例中，不同优先级的应用层数据包映射到同一QoS Flow，PDU会话的帧格式内引入ADU识别信息，ADU识别信息用于隐含指示ADU内数据包越靠前优先级越高。
图9是本申请实施例提供的另一种PDU会话的帧格式的配置示意图。PDU 会话的帧格式中携带如下至少之一：应用层数据单元的开始传输指示(Application Data Unit start mark)、结束传输指示(Application Data Unit end mark)。其中，ADU识别信息的指示位可占用2bit，指示位的四个取值分别表示如下至少之一：指示位不存在、一个应用层数据单元传输开始、一个应用层数据单元传输结束、一个应用层数据单元只有一个PDU。比如：当2bit为’00’时，表示指示位不存在(不指示应用层数据单元的开始与结束)，无法判断出应用层数据单元的开始与结束，或默认一个应用层数据单元对应一个PDU。
当2bit为’01’时，表示一个应用层数据单元的传输开始；当2bit为’10’时，表示一个应用层数据单元的传输结束；当2bit为’11’时，表示一个应用层数据单元只有一个PDU。
在实施例中，从一个应用层数据单元传输开始指示所在比特的DL QFI Sequence Number 1，到一个应用层数据单元传输结束指示所在比特的DL QFI Sequence Number 2，同一QoS flow下DL QFI Sequence Number在[DL QFI Sequence Number 1，DL QFI Sequence Number 2]区间内的所有PDU对应同一应用层数据单元。ADU识别信息可以隐含：同一应用层数据单元内的数据帧或PDU，序号越靠前越重要(调度优先级越高，可靠性要求越强)。
在一实施例中，ADU识别信息的指示位可占用1bit。在该bit为1的情况下，表示同一QoS flow下的应用层数据单元传输开始指示(start mark)或结束传输指示(end mark)(其中，新的开始传输指示就是旧的结束传输指示)。
在一实施例中，图10是本申请实施例提供的一种基于开始传输指示，指示同一ADU对应的PDU的配置示意图。在实施例中，1bit取值为1，表示一个应用层数据单元开始传输指示(start mark)，直到同一QoS flow下1bit再次为1之前，所有PDU对应一个应用层数据单元。
如图10所示，在PDU1里出现一次StartMark＝1,后续最近一次出现StartMark＝1的是PDU m+1，则PDU1，PDU2，...，PDU m对应同一应用层数据单元。
在一实施例中，图11是本申请实施例提供的一种基于结束传输指示，指示同一ADU对应的PDU的配置示意图。在实施例中，1bit取值为1，表示一个应用层数据单元结束传输指示(End mark)；该End mark对应的PDU及之前同一QoS flow下End mark＝0的连续PDU对应一个应用层数据单元。
如图11所示，在PDU m+1里出现一次EndMark＝1,该PDU及之前End mark＝0的连续PDU(PDU2，...，PDU m，PDU m+1)对应一个应用层数据单元。
在一实施例中，图12是本申请实施例提供的又一种PDU会话的帧格式的配置示意图。如图12所示，PDU会话的帧格式中携带如下至少之一：应用层数据单元序号(Application Data Unit Sequence Number)和应用层数据单元的结束传输指示(End mark)。其中，应用层数据单元序号用于基站识别PDU是否对应于同一应用层数据单元，同一QoS flow下相同应用层数据单元序号的PDU对应同一应用层数据单元；不同应用层数据单元序号的PDU对应不同应用层数据单元。应用层数据单元的结束传输指示用于指示同一应用层数据单元对应的最后一个PDU。
基于应用层数据单元序号，基站可以判断是否一个新的应用层数据单元的PDU开始传输以及不同PDU是否对应同一应用层数据单元；基于应用层数据单元的结束指示，基站可以判断一个应用层数据单元的PDU传输是否结束。例如图12中的End mark取值为1表示一个应用层数据单元的PDU传输结束。
从一个新的应用层数据单元的PDU开始传输，到一个应用层数据单元的PDU传输结束，同一QoS flow下相同应用层数据单元序号的PDU对应一个完整的应用层数据单元。
在一实施例中，也可以用当前PDU的应用层数据单元序号与后一个PDU的序号是否相同来识别当前PDU对应的应用层数据单元是否结束。如果一个新的应用层数据单元开始传输，隐含表示上一个应用层数据单元传输结束。此时不需要应用层数据单元的结束指示。
在一实施例中，图13是本申请实施例提供的再一种PDU会话的帧格式的配置示意图。如图13所示，在PDU会话的帧格式中携带如下至少之一：应用层数据单元开始传输指示(Start mark)、应用层数据单元的所包含的用户面数据包总数量(Packet Total Number in one Application Data Unit)。其中，从包含应用层数据单元开始标识的数据包开始，连续应用层数据单元的包含的用户面数据包总数量的数据包属于同一应用层数据单元。
在一实施例中，图14是本申请实施例提供的再一种PDU会话的帧格式的配置示意图。本实施例可以对图9、12和13进行组合、复用、多级包含来表示多级的应用层数据单元，比如：一级应用层数据单元为一个视频流(即应用层数据单元)，二级应用层数据单元为一个视频帧(即应用层数据帧/应用层数据包)，采用图12的配置方法进行二级包含，结果为图14所示(其中：Fist Level 和Second Level所在比特位置只是示例，实际占用比特数和占用比特位置可能会有差异，比如Fist Level和Second Level相关参数都放在PDU的扩展比特位置，或者引入新的PDU格式)。
如图14所示，对二级的应用层数据单元进行示例说明：第一级应用层数据单元表征视频流；第二级应用层数据单元表征视频帧。对应图1中的信息，可以填写为如下结构：
第一IP包：
First level End mark：0
First level Application Data Unit Sequence Number：1
Second level End mark：0
Second level Application Data Unit Sequence Number：1(I1帧开始)

First level Application Data Unit Sequence Number：1

Second level Application Data Unit Sequence Number：2
...
第n+m个IP包：
First level End mark：0
First level Application Data Unit Sequence Number：1
Second level End mark：1(B2帧结束)
Second level Application Data Unit Sequence Number：2
第n+m+1个IP包：
First level End mark：0
First level Application Data Unit Sequence Number：1
Second level End mark：0
Second level Application Data Unit Sequence Number：3(B3帧结束)
在一实施例中，不同QoS Flow的应用层数包帧映射到不同QoS flow，PDU会话的帧格式内引入QoS flow及PDU序号的依赖关系。
图15是本申请实施例提供的再一种PDU会话的帧格式的配置示意图。如图15所示，关联的QoS流标识QFI(Associated QoS Flow Identifier)和关联的下行QFI序号(Associated DL QFI Sequence Number)用于表征该PDU或该PDU对应应用层数据单元的解码与QoS Flow Associated QoS Flow Identifier和Associated DL QFI Sequence Number对应的PDU或对应PDU的应用层数据单元有关联关系、依赖关系、补充关系、主辅关系、从属关系或者时序关系；和/或用于表征该PDU与关联的PDU属于同一应用层消息，属于同一应用层数据单元或者属于同一类型的数据包。
比如只有解出QoS Flow Associated QoS Flow Identifier以及Associated DL QFI Sequence Number对应的PDU或对应PDU的应用层数据单元，才可以解出该PDU或该PDU对应应用层数据单元。
在一实施例中，图16是本申请实施例提供的再一种PDU会话的帧格式的 配置示意图。在PDU会话的帧格式中携带应用层数据单元中解码可容忍的丢包数。其中，应用层数据单元中解码可容忍的丢包数包括：应用层数据单元解码可容忍的最大丢包总数或最大连续丢包总数。所述丢包总数为丢失的用户面数据包总数或丢失的应用层数据包总数。如图16所示，PDU会话的帧格式中携带下述之一：应用层数据单元中可容忍的最大丢包总数以及应用层数据单元中可容忍的最大连续丢包总数。PDU会话的帧格式中还可以包括：应用层数据单元的开始传输指示以及应用层数据单元所包含的用户面数据包总数量。所述丢包总数为丢失的用户面数据包总数或丢失的应用层数据包总数。
在实施例中，应用层数据单元中解码可容忍的丢包数可通过核心网到基站的S1AP/NGAP信令的QoS flow包含的可容忍的丢包数指示，或者通过PDU格式里包含的可容忍的丢包数指示。
本实施例中，图16中的Maximal Lost packets tolerable可以指示ADU中可容忍的丢包总数量或可容忍的连续丢包总数量，如果丢包数大于Maximal Lost packets tolerable，则不满足应用层需求(比如导致应用层解码失败)。如果从StartMark标识的数据包开始，在Packet Total Number in one Application Data Unit的数据包内，丢失的数据包数目快要达到Maximal Lost packets tolerable时，则提高后续数据包传输的可靠性(比如激活PDCP Duplication或提高发射功率)；如果从Start Mark标识的数据包开始，在Packet Total Number in one Application Data Unit的数据包内，丢失的数据包数目达到了Maximal Lost packets tolerable时，则丢弃Packet Total Number in one Application Data Unit的数据包内未传输的数据包。
Maximal Lost packets tolerable可以基于应用层数据单元定义(比如图14中的第一级应用层数据单元)，也可以基于数据包类型进行定义(比如图14中的第二级应用层数据单元)。
在一实施例中，图17是本申请实施例提供的一种应用层数据单元中解码可容忍的丢包数的指示示意图；图18是本申请实施例提供的另一种应用层数据单元中解码可容忍的丢包数的指示示意图。核心网到基站的S1AP或NGAP信令的QoS流中所包含的应用层数据单元中解码容忍的丢包数，如图17所示，QoS子流中包含每个应用层数据单元中可容忍的最大丢包总数或最大连续丢包总数；如图18所示，QoS流中包含每个应用层数据单元中可容忍的最大丢包总数或最大连续丢包总数。
在一实施例中，应用层数据包识别信息中也可以包括：应用层数据包序号、应用层数据包的开始传输指示、应用层数据包的结束传输指示以及应用层数据 包所包含的用户面数据包总数量中的至少两个。在此需要说明的是，上述实施例中，对应用层数据包识别信息中的每个参数的解释同ADU识别信息中对应参数的描述，只是将应用层数据单元更换为应用层数据包。并且，上述实施例中对ADU识别信息的附图也适用于应用层数据包识别信息，在此不再一一赘述。
在一实施例中，图19是本申请实施例提供的一种LCG标识与QoS子流标识之间的配置关系图。本实施例以第一通信节点为基站，第三通信节点为UE为例，对不同优先级的数据帧映射到同一QoS Flow时，BSR优先级的区分进行说明。如图19所示，基站将同一QoS Flow里具有不同priority的QoS Sub-flow ID或sub-priority映射到不同LC ID上，再将不同LC ID映射到不同LCG ID，进而可以实现将同一QoS Flow里具有不同priority的QoS Sub-flow ID或sub-priority映射到不同LCG ID上。
在QoS映射时，SDAP映射时考虑了QoS Sub-Flow ID、SDAP与无线链路控制承载配置(Radio Link Control-BearerConfig，RLC-BearerConfig)同时与DRB相关联，所以QoS Sub-Flow ID也映射到RLC-BearerConfig上；而每个RLC-BearerConfig关联到一个LCG。
UE基于LCG ID进行BSR请求的情况下，可以对同一QoS Flow里具有不同priority的QoS Sub-flow ID或sub-priority进行BSR区分。
在一实施例中，BSR请求中不仅体现了QoS flow的优先级，也可以体现QoS sub-flow的优先级。
在一实施例中，不同priority的QoS Sub-flow ID或sub-priority也可以是图6所示的应用层数据包类型，BSR中还可以体现应用层数据包类型。
