传统的以太网络的转发过程中,当大量的数据包在一瞬间抵达转发端口,会造成转发时延大或者丢包的问题,因此传统以太网不能提供高可靠性以及传输时延有保障的服务,无法满足汽车控制、工业互联网等领域的需求。电气电子工程师学会(institute of electrical and electronic,IEEE)针对可靠时延传输的需求,定义了相关的TSN标准,该标准基于二层交换来提供可靠时延传输服务,保障时延敏感业务数据传输的可靠性,以及可预测的端到端传输时延。
IEEE 802.1cc中为TSN定义了3种配置模型,其中一种为全集中式TSN系统架构。如图2B所示,为全集中式TSN系统架构示意图,包括TSN终端(TSN End Station)、TSN交换节点(TSN Bridge)、集中式用户配置(Centralized User Configuration,CUC)网元和集中式网络配置(Centralized Network Configuration,CNC)网元,以下简称为CUC和CNC。其中,CUC和CNC属于控制面的网元。
其中:
1)、TSN终端为数据流的发送端或接收端;
2)、TSN交换节点按照TSN的定义为数据流预留资源,并对数据报文进行调度和转发;
3)、CNC管理TSN用户面的拓扑以及TSN交换节点的能力信息(例如TSN交换节点的传输时延(指从当前TSN交换节点的端口发送TSN流,到TSN流到达下一跳交换节点的端口之间经过的时间)、TSN交换节点的端口间的内部处理时延(TSN流从当前TSN交换节点的入端口进入,到从该TSN交换节点的出端口发出之间经过的时间))。
4)CNC根据CUC提供的流创建请求消息,创建TSN流转发规则以便生成数据流的转发路径,生成TSN终端和各TSN交换节点上的调度策略或调度规则(包括收发TSN流或聚合了一个或多个TSN流的TSN业务类别(traffic class)对应的报文的端口(入端口(也称为接收端口)和出端口(也称为发送端口))、在入端口的接收时间窗口(可选)、在出端口的发送时间窗口、发送周期等),之后将TSN交换节点上的调度策略或调度规则下发到对应的TSN交换节点;所述各TSN交换节点上的调度策略或调度规则是CNC根据网络拓扑信息以及各TSN交换节点上报的能力信息确定的。
CNC在创建TSN流转发规则后,可通过向TSN交换节点下发静态表(Static filtering entries)的方式确定TSN交换节点上流的转发路径。静态表的信息包含TSN流的目的媒体接入控制(medium access control,MAC)地址、该TSN流在TSN交换节点上的接收端口的标识和发送端口的标识,可选的,静态表的信息还包含虚拟本地区域网络(Virtual Local Area Network,VLAN)标识(ID)。
需要说明的是,上述提到的CNC发送给交换节点的调度策略或调度规则的表现形式不同,取决于TSN系统定义的不同的调度算法。本发明以IEEE802.1Qbv定义的调度算法为例,CNC给交换节点发送IEEE802.1Qbv定义的调度参数,包括TSN交换节点端口的门控信息,该门控信息可以包括所述端口的门控操作周期开始执行的时间(即IEEE802.1Qbv中的AdminBaseTime),队列的门控状态(即IEEE802.1Qbv中的GateStateValue)和门控状态的持续时间(即IEEE802.1Qbv中的TimeIntervalValue)。交换节点根据所述调度参数确定出端口的发送时间窗口,发送周期,可选的,还可以确定入端口的接收时间窗口。
5)、CUC用于收集TSN终端的流创建请求,如接收TSN发送终端(Talker)和TSN接收终端(Listener)的注册,接收流的信息,交换配置参数等,在匹配TSN发送终端和TSN接收终端的请求后,向CNC请求创建数据流,并对CNC生成的调度策略进行确认。
如图3A所示,为5G系统与TSN互通系统架构示意图。即将图2A所示的5G架构和图2B所示的TSN架构相结合,将5G系统和TSN转换器(TSN Translator)整体作为一个逻辑上的TSN交换节点(称为5G系统交换节点),实现TSN中交换节点的功能的假设。TSN转换器指的是将5G网络的特征和信息转换和适配成TSN要求的信息,提供给TSN系统,或将TSN系统要求的信息转换成针对5G网络的特征或信息,提供给5G系统。其中,图3A中仅示出了5G架构中的部分网元(即AMF网元、SMF网元、PCF网元、RAN、UE、AF网元、UPF网元)。
1)、在控制面,5G系统通过控制面的TSN转换器(即5G的AF网元),与TSN系统中的节点交换信息,所交换的信息包括:5G系统交换节点的能力信息、TSN配置信息(包括TSN输入输出端口的时间调度信息)等。
其中,AF网元将5G系统交换节点的能力信息提供给TSN系统中的CNC,CNC根据5G系统交换节点的能力信息,以及其它TSN交换节点的能力信息为TSN业务确定5G系统交换节点的TSN配置信息。AF网元将CNC确定的针对5G系统交换节点的TSN配置信息提供给5G系统交换节点。

作为一个示例,本申请中的终端设备,可以是具有图3A所示的UE的功能的设备,该终端设备中可以集成有TSN转换器,或者是该TSN转换器独立于终端设备部署,为方便说明,本申请以TSN转换器集成于终端设备为例进行说明。为方便说明,本申请后续描述中将该终端设备称为UE。
针对图3A所示的网络架构,CNC根据5G系统交换节点以及其它TSN交换节点上报的信息给每个交换节点(包括5G系统交换节点和其它TSN交换节点)配置针对TSN业务的调度策略或调度规则,5G系统交换节点以及其它TSN交换节点可以根据所述调度策略或调度规则中包括的门控信息,确定端口对应的调度参数,包括:端口对不同TSN业务报文的发送时间窗口(用于限定交换节点的出端口在时间窗口内发送TSN业务报文)、接收时间窗口(可选,用于限定交换节点的入端口在时间窗口内接收TSN业务报文)、业务周期等,以根据CNC的配置在确定的时间窗口内发送和/或接收TSN业务报文,去除时延抖动,保证TSN业务的确定性传输。作为又一种实现方式,CNC还可以直接向每个交换节点下发上述调度参数。对于5G系统交换节点,其端口包括UE或UE侧的TSN转换器的端口以及UPF或UPF侧的TSN转换器的端口。
以下行为例,CNC通过AF向PCF发送TSN业务的调度参数,PCF再将调度参数作为策略信息中QoS参数的一部分提供给SMF,SMF再下发给UE,UE侧的TSN转换器根据调度参数中定义的门控信息在相应的出端口对TSN流进行发送处理。
为了优化RAN对空口资源的调度保证5G系统交换节点对TSN业务确定性传输的支持,还可以向RAN提供TSN业务的调度参数,RAN根据所述调度参数调度空口资源和执行准入控制,如提前准备好空口资源,或者在发现TSN业务报文实际到达时间晚于调度参数所定义的时间窗口时直接丢弃下行TSN业务报文或者是指UE丢弃上行业务报文以节省空口资源,保证UE或UPF可以及时接收到TSN业务报文。
在目前的现有技术中,5G系统支持5G系统的时钟域和多个TSN时钟域,一个TSN终端支持一个TSN时钟域。由于5G系统交换节点是以5G系统的时钟为参考基准进行时钟同步的,因此存在5G系统交换节点与TSN终端之间时钟域不同,而导致时钟偏差的问题。下面结合一个示例进行说明。
如图3B所示,为5G网络与TSN互通系统的一个具体示例。其中,5G系统交换节点支持5G时钟域、TSN时钟域1、TSN时钟域2,TSN终端1和TSN终端2支持TSN时钟 域1,TSN终端3和TSN终端4支持TSN时钟域2。
由于TSN终端1和TSN终端2支持TSN时钟域1,因此,TSN终端1和TSN终端2上的应用的TSN业务的调度参数是以TSN时钟域1的时钟为参考设置的。类似的,TSN终端3和TSN终端4上的应用的TSN业务的调度参数是以TSN时钟域2的时钟为参考设置的。
比如,当TSN终端1向TSN终端2发送TSN流时,CNC会将TSN业务的调度参数(该调度参数是以TSN时钟域1的时钟为参考设置的)发送至5G系统交换节点,并且5G系统交换节点是按照5G时钟域来理解该调度参数的,因而导致出现时钟偏差的问题。
此外,需要说明的是,如前所述,CNC给各个TSN交换节点下发的调度策略或调度规则是CNC根据网络拓扑信息以及各个TSN交换节点上报的能力信息确定的,而TSN交换节点的能力信息包括TSN交换节点的传输时延、TSN交换节点的端口间的内部处理时延等时间相关的信息。
也就是说,5G系统交换节点作为一种具有TSN交换节点使能功能的虚拟交换节点,也要将其能力信息提供给CNC,以便于CNC根据5G系统交换节点的能力信息,以及其它TSN交换节点的能力信息为TSN业务确定5G系统交换节点的TSN配置信息。
5G系统交换节点的能力信息可以包括5G系统交换节点的传输时延和5G系统交换节点的内部处理时延,而5G系统交换节点的内部处理时延是以5G时钟域的时钟源的时间为参考的,CNC直接根据该时延信息确定TSN配置信息,也会出现时钟偏差的问题,从而影响确定性传输的实现。
比如,5G系统上报的5G系统交换节点的内部处理时延为5ms,如果考虑5G时钟和TSN终端对应的时钟域的时间之间的频率偏差,以TSN时钟域的时钟为参考该内部处理时延为5.01ms。
因此SMF或AF应该对5G系统上报的交换节点能力信息中包括的时延信息进行转换处理,将其转换为TSN时钟对应的时延信息,再上报给CNC,以便于CNC根据以TSN时钟域的时钟为参考的5G系统交换节点的时延信息确定调度策略和调度规则,保证TSN业务的确定性传输。具体的,可以是SMF或AF获取5G时钟和TSN时钟域的时钟之间的时钟偏差,再根据时钟偏差将收集的基于5G时钟的5G系统交换节点的时延信息转换为基于TSN时钟域的时钟为参考的5G系统交换节点的时延信息。

为解决背景技术的问题,本申请提供一种TSN业务的处理方法,如图4所示,该方法包括以下步骤:
步骤401,第一设备获取TSN业务的第一调度参数和TSN业务对应的TSN时钟域信息。
作为一种实现方法,第一设备可以在会话修改流程中,从SMF获取TSN业务的第一调度参数和TSN时钟域信息。比如,第二设备(如PCF),可以从UDR、PCF、或AF获取TSN业务对应的TSN时钟域信息,以及从AF获取TSN业务的第一调度参数,然后在会话修改流程中,将TSN业务的第一调度参数和TSN业务对应的TSN时钟域信息发送给SMF,由SMF再发送给第一设备。再比如,在会话修改流程中,第二设备(如SMF),可以从数据库或SMF获取TSN业务对应的TSN时钟域信息,以及从PCF获取TSN业务的第一调度参数,然后SMF将TSN业务的第一调度参数和TSN业务对应的TSN时钟域信息发送给第一设备。

作为又一种实现方法,在上述步骤401之后也可以不执行步骤402和步骤403,而是通过以下方法传输TSN业务的报文:第一设备上配置有5G系统的时钟和至少一个TSN时钟域的时钟,第一设备在接收到第一调度参数和TSN业务对应的TSN时钟域信息之后,则基于该接收到的TSN业务对应的TSN时钟域的时钟来理解该第一调度参数,因此第一设备可以直接基于该TSN业务对应的TSN时钟域信息,根据该第一调度参数传输TSN业务的报文。
为解决背景技术的问题,本申请提供又一种TSN业务的处理方法,如图5所示,该方法包括以下步骤:
步骤501,第二设备获取TSN业务的第二调度参数。
第二设备获取TSN业务的第二调度参数的具体方式为:第二设备确定TSN业务对应的TSN时钟域的时钟与5G系统的时钟的时钟偏差,以及获取TSN业务的第一调度参数,然后根据第一调度参数和该时钟偏差确定第二调度参数。其中,若第二设备是AF,则AF获取第一调度参数的方法比如可以是:从CNC获取该第一调度参数。若第二设备是SMF,则SMF获取第一调度参数的方法比如可以是:从PCF或AF获取该第一调度参数,而PCF可以是从AF获取第一调度参数的,AF则可以是从CNC获取第一调度参数的。
需要说明的是,本申请对第二设备获取时钟偏差的方式不做限定,比如可以是:第二设备同时与5G系统的时钟和TSN时钟域的时钟同步,第二设备从而确定5G系统的时钟和TSN时钟域的时钟偏差;也可以是:当第二设备从UE或UPF获取5G时钟域和TSN时钟域的时钟偏差;也可以是:当第二设备是AF时,SMF从UE或UPF获取5G时钟域和TSN时钟域的时钟偏差,然后AF再从SMF获取所述时钟偏差。SMF从UE或UPF获取5G时钟域和TSN时钟域的时钟偏差的方式,本发明也不做限定,可以是UE或UPF根据预配置方式向SMF上报5G时钟和各TSN时钟域的时钟偏差,也可以是SMF向UE或UPF发送时钟偏差获取请求,UE或UPF根据请求中携带的TSN时钟域信息(如时钟域ID)上报5G时钟和各TSN时钟域的时钟偏差。
作为一种可替代的实现方式,当第二设备为SMF时,SMF也可以直接从AF获取第二调度参数,而AF获取第二调度参数的方法,可以AF根据第一调度参数和时钟偏差确定,具体实现过程可以参考前述描述。
步骤502,第二设备根据第二调度参数,确定第三调度参数。

步骤505,第二设备向第一设备发送第二调度参数。相应地,第一设备可以接收到该第二调度参数。
步骤506,第一设备根据第二调度参数,传输该TSN业务的报文。
需要说明的是,若不执行上述步骤505-步骤506,则第一设备可以通过图4实施例的方法获取到第一调度参数,然后第一设备根据第一调度参数确定第二调度参数,并根据第二调度参数,传输该TSN业务的报文。
需要说明的是,第二设备向RAN发送第三调度参数和向第二设备发送第二调度参数的方式,本发明不做限定,例如,当第二设备为AF时,AF可以通过SMF向RAN发送第三调度参数,以及AF向第一设备发送第二调度参数;AF也可以先向PCF发送第三调度参数和第二调度参数,PCF再将第三调度参数和第二调度参数发送给SMF,然后SMF发送第三调度参数给RAN,以及发送第二调度参数给第一设备;AF也可以直接向第一设备发送第二调度参数。
基于上述实施例,第二设备可以获取到TSN业务的第二调度参数,该第二调度参数是基于5G系统的时钟进行设置的,第二设备根据第二调度参数确定第三调度参数,并将第三调度参数发送至RAN,从而RAN可以根据第三调度参数传输TSN业务的报文,进一步的,第二设备还可以向第一设备发送第二调度参数,从而第一设备可以根据第二调度参数传输TSN业务的报文,实现了接入网对TSN业务的报文的正确传输,有助于提升通信质量。
下面给出两个具体实施例(图6实施例和图7实施例),对图4所示的实施例进行介绍说明。
如图6所示,为本申请提供的又一种TSN业务的处理方法流程示意图。该方法包括以下步骤:
步骤601,CNC基于TSN终端的TSN业务的QoS需求,确定传输路径和对TSN交换节点的调度传输要求,通过AF向5G系统交换节点发送TSN业务的QoS需求,CNC还向5G系统交换节点的AF发送TSN业务的第一调度参数。
作为一种实现方法,CNC向AF发送调度规则,该调度规则包括第一调度参数。该TSN业务调度规则用于指示TSN交换节点传输TSN业务的报文的时间信息,比如在什么发送时间窗口发送报文,再比如在什么接收时间窗口接收报文等。
作为一种具体实现方法,CNC可以向AF发送交换节点配置请求(Bridge configuration Request)消息,该请求消息中携带TSN QoS需求(QoS requirement)、TSN业务的第一调度参数。
步骤602,AF向PCF发送TSN业务的QoS需求和TSN业务的第一调度参数。
作为一种具体实现方法,AF可以向PCF发送TSN流请求(TSN Stream Request)消息,该请求消息中携带TSN业务的第一调度参数和TSN业务的QoS需求,进一步地还可以携带应用的标识(APP ID)或业务模板(traffic filtering)信息。其中,业务模板信息包括五元组信息,用于过滤报文。
应用的标识和业务模板均可以用于标识应用。
该TSN业务指的是该应用的标识或业务模板所指示的应用的业务。
步骤603,PCF从UDR获取应用的标识对应的TSN时钟域信息。
其中,UDR中存储有应用的标识与TSN时钟域信息之间的对应关系。因此,PCF可以基于应用的标识,向UDR请求获取与该应用的标识对应的TSN时钟域信息。
作为该步骤603的一种可替代实现方式,PCF可以在PCF上存储有应用的标识与TSN时钟域信息之间的对应关系,或者存储有业务模板与TSN时钟域信息之间的对应关系,则PCF可以从PCF获取应用的标识(或业务模板)对应的TSN时钟域信息。
作为该步骤603的又一种可替代实现方式,PCF还可以从AF获取应用的标识(或业务模板)对应的TSN时钟域信息。比如,在上述步骤602中,AF除了向PCF发送TSN业务的第一调度参数,还向PCF发送应用的标识(或业务模板)对应的TSN时钟域信息。
其中,应用的标识对应的TSN时钟域信息,即为该应用的TSN业务对应的TSN时钟域信息。
步骤604,PCF根据TSN业务的QoS需求,确定策略和计费控制(Policy and Charging Control,PCC)规则。
该步骤为现有技术,可参考现有技术相关描述。
步骤605,PCF向SMF发送策略更新通知请求消息,相应地,SMF可以接收到该策略更新通知请求消息。
该策略更新通知请求消息中携带TSN业务的第一调度参数和TSN业务对应的TSN时钟域信息。该步骤中,该策略更新通知请求消息通知SMF更新PDU会话的策略信息,以触发PDU会话修改流程。其中,策略信息中包括TSN业务的第一调度参数和TSN时钟域信息。
作为一种实现方式,该策略更新通知请求可以是Npcf_SMPolicyControl_updateNotify request。
步骤606,SMF向PCF发送策略更新通知响应消息。相应地,PCF可以接收到该策略更新通知响应消息。
该步骤为可选步骤。作为一种具体实现方式,该策略更新通知响应消息比如可以是Npcf_SMPolicyControl_updateNotify response。
步骤607,SMF发起会话修改流程,根据PCF发送的策略信息建立一个新的QoS流(QoS Flow)或更新一个现有的QoS流。
该步骤为现有技术,可参考现有技术相关描述。
步骤608,SMF向UE/UPF发送TSN业务的第一调度参数和该TSN业务对应的TSN时钟域信息。
作为该一种具体实现方式,SMF可以向UE发送QoS规则(QoS rule),在QoS rule中携带TSN业务的第一调度参数和该TSN业务对应的TSN时钟域信息。
作为一种具体实现方式,SMF可以向UPF发送N6业务路由信息(N6 Traffic routing Info),在N6 Traffic routing Info中携带TSN业务的第一调度参数和该TSN业务对应的TSN时钟域信息。
需要说明的是,该步骤中,SMF可以向UE或UPF发送TSN业务的第一调度参数和该TSN业务对应的TSN时钟域信息,也可以是向UE和UPF均发送TSN业务的第一调度参数和该TSN业务对应的TSN时钟域信息,本申请对此不作限定。
步骤609、UE/UPF根据TSN业务的第一调度参数和该TSN业务的时钟域信息,传输该TSN业务的报文。
该步骤的具体实现方法可以参考图4所示的实施例的步骤402的相关描述,这里不再赘述。
基于该实施例,UE/UPF分别根据第一调度参数和TSN时钟域的时钟处理TSN业务的报文,实现了对TSN业务的报文的正确传输,有助于提升通信质量。
如图7所示,为本申请提供的又一种TSN业务的处理方法流程示意图。该方法包括以下步骤:
在会话建立流程中(包括以下步骤701-步骤703):
701,SMF接收UE发送的会话建立请求消息。
该会话建立请求消息用于请求建立会话。
在具体实现中,该会话建立请求消息可以是PDU会话建立请求(PDU Session Establishment Request)消息,该请求消息中可以携带单网络切片选择辅助信息(single network slice selection assistance information,S-NSSAI)和数据网名称(Data Network Name,DNN)。
步骤702,SMF从UDR获取TSN时钟域信息。
其中,UDR中存储有会话信息(如S-NSSAI和/或DNN)与TSN时钟域信息之间的对应关系。因此,SMF可以基于会话信息,向UDR请求获取与该会话信息对应的TSN时钟域信息。
作为该步骤702的一种可替代实现方式,SMF可以在SMF上存储有会话信息与TSN时钟域信息之间的对应关系,则SMF可以从SMF获取会话信息对应的TSN时钟域信息。
需要说明的是,一个会话信息可以对应一个TSN业务,因此这里的会话信息对应的TSN时钟域信息,也可以理解为TSN业务对应的TSN时钟域信息。
步骤703,SMF向UE和/或UPF发送会话信息对应的TSN时钟域信息。
