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。

首先,对本公开涉及的应用场景进行说明:
扩展现实和媒体业务(XRM,Extended Reality and Media)业务包括移动媒体类服务、增强现实(AR,Augmented Reality)和/或虚拟现实(VR,Virtual Reality)等。XRM业务、云游戏、基于视频的机器和/或无人机远程控制等业务,预计将为无线通信网络贡献越来越高的流量,例如,音视频流的流量。
XR业务包括多模态数据流。例如,除了上述的音视频流外,还涉及生物触觉感知等数据流。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相关性,例如,音频流和视频流的同步,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,都存在一些业务特征,有效识别和利用这些业务特征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,在无线通信网络采用的是通用QoS机制处理包括XR业务在内的各类数据服务时,没考虑到XR业务的业务特性,无法有效地支持这些业务差异化的上下行需求。例如,上行数据可靠性和下行数据高带宽的非对称需求。同时,包括XR业务在内的数据流具有高带宽、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单元集的QoS需求。(例如,Qos需求需要匹配数据单元集中数据单元之间的依赖关系、数据单元集之间的依赖关系、数据单元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单元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。目前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丢包处理方法,其中,所述方法由接入网节点执行,所述方法包括:
步骤21、向第一网络功能发送指示信息;
其中,所述指示信息用于指示以下至少之一:基于分组数据单元(Packet Data Unit,PDU)集的服务质量QoS流处理的丢包事件信息;以及基于PDU集的QoS流处理的丢包指示信息。
本公开中涉及的接入网节点可以是基站,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。在一个示例中,本公开中涉及的接入网节点可以为上述图1所述的基站120。
本公开中涉及的网络功能可以为核心网中的设备,如图1中的核心网设备,例如,第一网络功能为用户面功能(UPF,User Plane Function);第二网络功能为网络暴露功能(NEF,Network Exposure Function);第三网络功能为策略控制功能(PCF,Policy Control Function);第四网络功能为会话管理功能(SMF,Session 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。

为了更好地理解本公开实施例,以下通过一个示例性实施例对本公开技术方案进行进一步说明:
示例1:
请参见图19,提供一种丢包处理方法,其中,所述方法包括:
步骤191、事件被触发。
在一个示例中,网络拥塞事件被触发。
步骤192、当基于PDU集的QoS处理丢包事件(例如,拥塞情况)发生时,NG RAN在上行UL数据的报头中指示该事件和/或指示(对应本公开中指示信息)。如果没有UL数据,NG RAN会创建一些UL虚拟数据包进行报告;
步骤193、UPF向NEF发送Nupf_EventExposure_Notify消息(该Nupf_EventExposure_Notify消息中包括测量报告、事件和指示信息的至少之一);
步骤194、如果AF订阅了通知,NEF向AF发送Nnef_Nnef_EventExposure_Notify(该Nupf_EventExposure_Notify消息中包括测量报告、事件和指示信息的至少之一)消息;
步骤195、NEF将通知信息存储在UDR中;
步骤196、如果UE注册到网络,并且PCF通过调用Nudr_DM_Subscribe对UDR中的数据订阅了数据更新通知,则UDR发送PDU的Nudr_DM_Notify通知基于设置的QoS处理数据包丢弃事件信息到PCF;其中,Nudr_DM_Subscribe可以包括基于PDU集的QoS处理丢包事件信息和注册用户永久识别码(SUPI,Subscription Permanent Identifier)信息。
步骤197、PCF根据收到的事件和/或指示,确定是否对相应基于PDU集QoS处理数据流执行主动 丢包。需要说明的是,若PCF未部署,则SMF执行相应会话修改和规则更新。
PCF发起PDU会话修改流程,通知或者授权SMF对相应业务数据流、数据单元集和/或数据包执行主动丢包。SMF基于更新后的规则配置UPF,UPF对相应业务数据流、数据单元集和/或数据包执行主动丢包;
具体可结合PDU集参数和丢包策略执行丢包。例如,基于PDU集的时延或重要程度,整体或部分丢弃PDU集的数据包;基于丢包窗口执行丢包,基于不同数据流的优先级,对特定时延或重要程度的数据流执行丢包(例如,音视频电话中,保留音频,选择性丢弃视频流数据包)。
在本公开实施例中,NG RAN向PDU发送指示信息;其中,所述指示信息用于指示以下至少之一:基于分组数据单元PDU集的服务质量QoS流处理的丢包事件信息;基于PDU集的QoS流处理的丢包指示信息。这里,由于NG RAN向PDU发送了基于分组数据单元PDU集的服务质量QoS流处理的丢包事件信息和/或基于PDU集的QoS流处理的丢包指示信息,所述PDU在接收到所述丢包事件信息和/或丢包指示信息后,网络就可以基于所述丢包事件信息和/或丢包指示信息执行丢包处理,相较于不发送所述指示信息的方式,网络可以基于所述指示信息执行丢包操作,在出现拥塞时,提升业务数据流的传输效率,提升QoS,给用户带来好的体验。
示例2:
请参见图20,提供一种丢包处理方法。
基于PDU集的策略和计费控制可以发生在PDU会话建立或修改流程期间。本公开实施例由通信设备执行,通信设备包括:UE、RAN功能节点、AMF、SMF、PCF、UPF以及AF;信息处理方法包括以下步骤:
步骤201:执行现有的PDU会话建立流程的步骤1-7a;
步骤202:AF可以通过Nnef_AFsessionWithQoS_Create请求向PCF发送信息;
这里,该信息可以是QoS流中每个PDU集的QoS参数和/或关于帧标识的参数。AF也可以在PDU会话建立之前向5GS提供该信息。其中,
QoS流中每个PDU集的QoS参数,包括以下至少之一:
PDU集处理指示,其中,PDU集处理指示用于指示基于PDU集的处理是否被激活到数据流;
指示应用层的PDU集使用是否需要所有的PDU的参数;
PDU集延迟预算(PSDB);
PDU集错误率。
其中,帧标识的参数,包括突发周期。
步骤203:PCF生成PCC规则信息;并将PCC规则信息发送给SMF;
这里,PCC规则信息可包括QoS参数。PC和/或SMF生成规则信息,对下行XRM数据流执行调度优化或选择性流控(例如拥塞等事件触发的主动丢包);其中,UPF调度的预测结果,可以为NWDAF的网络分析结果(网络拥塞),或者RAN功能节点上报的事件通知结果(例如网络拥塞),PCF决策时考虑该预测结果生成PCC规则信息。
其中,PDU集相关QoS参数为用于5GS中PDU集的QoS处理新QoS参数;QoS参数包括以下指 示之一:
PDU集延迟预算(PSDB);
PDU集错误率;
指示应用层的PDU集使用是否需要所有的PDU的参数;
在超过PSDB的情况下是否丢弃PDU集的参数;
PDU集的优先级或者PDU的优先级。“PDU集优先级”对于所有PDU集是相同的(即,与现有QoS流优先级相同),或者对于每个PDU集是不同的(即,与“PDU集重要性”相同)。
该步骤在PDU会话建立流程中的步骤7b中完成,或者在PDU会话修改流程中的步骤1b中完成。(PDU会话建立流程,PDU会话修改流程)
如果该步骤由步骤1b触发,则PCF考虑由AF提供的信息来生成PCC规则信息。
步骤204:SMF配置RAN功能节点和UPF;
SMF基于来自PCF的PCC规则信息生成QoS配置文件和N4规则信息。SMF将N4规则信息发送到UPF,并且经由AMF将QoS配置文件发送到RAN功能节点。
这里,步骤通过PDU会话建立流程中的步骤8-15或者PDU会话修改流程中的步骤2-7来完成。
步骤205:执行PDU会话建立流程或者会话修改流程的剩余步骤;
步骤206:基于N4规则信息和/或UPF上的本地配置,UPF识别相关信息;并根据N4规则执行基于PDU集的QoS处理;
这里,UPF识别的相关信息包括以下至少之一的信息:
UPF基于此前安装的PCF和/或SMF生成并下发的规则信息;执行对下行XRM数据执行优化调度和/或选择性丢包(例如,拥塞等事件触发的主动选择性丢包);优化粒度可以为:数据流、PDU集或者数据包;和/或优化条件可以为:预定时间窗口、预定流量阈值或者预定丢包比例(丢包率阈值)。
UPF识别属于一个PDU集的PDU以及每个PDU集的以下至少之一的信息:
PDU集序列号(SN)(使用QoS流标识信息来标识QoS流,并且使用PDU集SN来标识QoS流内的每个PDU集。每个QoS流可用于传递一个或多个PDU集);
PDU集的开始或者结束PDU
PDU集中的PDU SN
PDU集中PDU的数量。
PDU集间处理的信息,包括以下至少之一信息:
PDU集重要性关系;
PDU集依赖关系。
这里,UPF通过以下方法/机制识别相关信息:

选项2:新的RTP扩展报头;
选项3:通过由N6封装报头中的AS提供的信息,例如GTP-U;
选项4:通过基于流量特征的检测;
选项5:通过非标准化机制UPF实施。
步骤S207:UPF发送PDU集通知给RAN功能节点;
这里,UPF将上述PDU集相关信息(在步骤S1205的相关信息中列出)提供给RAN功能节点。
对于PDU集的重要性关系,可以选择以下至少之一:
选型1:UPF基于PDU集重要性关系将下行(DL)业务分类为不同的QoS流;
选项2:UPF基于PDU集重要性关系将下行业务分类为不同的子QoS流
选项3:UPF将PDU集重要性关系添加到GTP-U报头中,
对于步骤5中的其他PDU集的相关信息,UPF将它们添加到GTP-U报头中。
步骤208:RAN功能节点执行PDU集的QoS处理。
这里,基于步骤S1206接收的PDU集的相关信息,执行PDU集的QoS处理。
若为RAN功能节点执行预测条件的监控和上报,则RAN功能节点执行PDU集的服务质量QoS处理(PDU set based QoS handling)流程中,当检测到丢包的触发事件(例如,拥塞程度大于阈值,丢包率大于阈值,时延大于阈值,UE的状态相关需求等),则上报PDU集的服务质量QoS处理数据包的丢包事件信息和/后丢包指示信息给核心网(CN)。
CN-CP功能根据收到的PDU集的QoS处理数据包的丢包事件信息和/或丢包指示信息,确定是否对PDU集的QoS处理数据包(PDU Set based QoS handling packets)执行丢包操作(例如主动丢包)。
例如,PDU集的QoS处理数据包的丢包事件信息,用于指示下行XRM业务数据流符合条件的触发条件(trigger/conditions of XRM service downlink traffic eligible dropping),该触发条件包括网络拥塞(网络拥塞程度拥塞参数大于拥塞阈值)、丢包率大于丢包率阈值、时延大于时延阈值以及UE状态相关需求。其中,UE状态相关需求包括过热、电池、电源模式状态和/或GPU负载平衡的状态需求。
例如,PDU集的QoS处理数据包的丢包指示信息,用于指示是否需要执行符合条件的丢弃下行XRM业务数据流;或者用于指示是否允许执行符合条件的丢弃下行XRM业务数据流。
