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2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。其中，CUC网元和CNC网元属于控制面的网元。
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交换节点的发送时延、TSN交换节点的端口间的内部处理时延)，并根据CUC提供的流创建请求，生成数据流的转发路径以及终端和各TSN交换节点上的处理策略(例如流标识、收发报文的端口、接收时间窗口、发送时间窗口、发送周期等)，之后将TSN交换节点上的处理策略下发到对应的TSN交换节点；
4)、CUC网元用于收集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网元请求创建数据流，并对CNC网元生成的处理策略进行确认。
CNC网元在创建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)。
如图3所示，为3GPP网络与TSN互通系统架构示意图。即将图1所示的5G架构和图2所示的TSN架构相结合，将3GPP 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)。其中，图3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)。
其中：
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系统的交换能力信息、TSN配置信息、TSN输入输出端口的时间调度信息、时间同步信息等。

为解决背景技术中提到的问题，本申请提供一种通信方法，如图5所示，该方法包括以下步骤：
步骤501，AF获取端口的处理策略信息。
比如，由CNC确定端口的处理策略信息，然后发送给AF。该处理策略信息包括端口的标识和数据流的处理策略。
作为一种实现方式，该处理策略信息可以是数据流的处理策略信息。比如该处理策略信息中还可以包括数据流的优先级列表，此时处理策略信息中的数据流的处理策略与数据流的优先级具有对应关系。或者理解为，一个数据流的优先级对应一种数据流的处理策略。比如，该数据流的优先级列表包括业务类型(Traffic class)，一个业务类型对应一种优先级，数据流的优先级对应的数据流的处理策略可以是门控信息列表(也可以称为时间片或调度时间片)。
作为又一种实现方式，处理策略信息中的数据流的处理策略可以是端口的配置策略，比如配置策略可以是发送端口的使能配置、VLAN配置等。
步骤502，AF根据端口的标识，确定UE的会话的标识。
AF接收到处理策略信息后，从处理策略信息中获取端口的标识，进而可以根据该端口的标识确定UE的会话的标识(比如可以UE的MAC地址等)。
其中，AF根据端口的标识确定UE的会话的标识的方式，比如可以是：
1)、在端口的标识为UE的端口的标识的情况下，AF根据端口的标识，确定端口的标识对应的UE的会话的标识。
2)、在端口的标识为UPF的端口的标识的情况下，AF根据端口的标识确定UE的端口的标识，然后确定UE的端口的标识对应的UE的会话的标识。
比如，AF根据UPF的端口的标识和UE的端口的标识之间的对应关系，确定UPF的端口的标识对应的UE的端口的标识，然后根据UE的端口的标识，确定UE的端口的标识对应的UE的会话的标识。
作为又一种实现方法，在端口的标识为UPF的端口的标识的情况下，AF从AF上保存的5G系统交换节点的UE的端口的标识中选择一个UE的端口的标识，然后根据UE的端口的标识，确定UE的端口的标识对应的UE的会话的标识。
步骤503，AF向第二设备发送端口的处理策略信息和UE的会话的标识。相应地，第二设备可以接收到该端口的处理策略信息和UE的会话的标识。
这里的第二设备可以是PCF、或SMF、或UPF。
比如，当第二设备是PCF时，则AF可以直接向PCF发送端口的处理策略信息和UE的会话的标识，也可以通过NEF向PCF发送端口的处理策略信息和UE的会话的标识。
比如，当第二设备是SMF时，则AF可以通过PCF向SMF发送端口的处理策略信息和UE的会话的标识。
再比如，当第二设备是UPF时，则AF可以通过PCF和SMF向UPF发送端口的处理策略信息和UE的会话的标识，或者通过SMF向UPF发送端口的处理策略信息和UE的会话的标识，或者直接向UPF发送端口的处理策略信息和UE的会话的标识。
作为一种实现方式，AF还可以向第二设备发送第一指示信息，用于指示处理策略信息对应的第一设备的类型，该类型可以是UE或UPF。或者理解为，该第一指示信息用于指示处理策略信息中的端口的标识指示的端口是UE的端口还是UPF的端口。或者还可以理解为，该第一指示信息用于指示该处理策略信息是UPF的端口的处理策略信息还是UE的端口的处理策略信息。从而第二设备可以根据第一指示信息，确定第一设备的类型，即确定该处理策略信息需要发给UE还是UPF。
作为又一种实现方法，若AF不向第二设备发送上述第一指示信息，则第二设备可以通过解析接收到的处理策略信息，从中获取到端口的标识，并识别出该端口的标识对应的端口是UE的端口还是UPF的端口，从而确定该处理策略信息需要发给UE还是UPF。
步骤504，第二设备根据UE的会话的标识，确定第一设备。
该第一设备可以是UE或UPF。比如，若第二设备确定第一设备的类型是UE，即确定处理策略信息是需要发送UE的，则该步骤中，第二设备根据UE的会话的标识，确定一个UE。再比如，若第二设备确定第一设备的类型是UPF，即确定处理策略信息是需要发送UPF的，则该步骤中，第二设备根据UE的会话的标识，确定一个UPF。
步骤505，第二设备向第一设备发送端口的处理策略信息。相应地，第一设备可以接收到端口的处理策略信息。
比如，第二设备是PCF，则PCF可以通过SMF，向会话对应的UE或UPF发送处理 策略信息。
比如，第二设备是SMF，第一设备是UPF，则SMF可以通过UE的N4会话或通过SMF与UPF之间的设备粒度的接口，向会话对应的UPF发送处理策略信息。
再比如，第二设备是SMF，第一设备是UE，则SMF可以通过NAS消息或通过UPF，向会话对应的UE发送处理策略信息。
可选的，第二设备还可以向第一设备发送一个第二指示信息，用于指示处理策略信息是端口的策略信息。
第一设备接收到上述处理策略信息之后，可以将根据该处理策略信息，配置相应的端口(即处理策略信息的端口的标识对应的端口)，或者还可以将处理策略信息发送至TSN转换器，由TSN转换器配置端口。
该实施例，基于现有5G管理和转发架构，实现TSN管理系统对5G系统交换节点的端口的处理策略的配置，从而使能5G系统交换节点支持TSN协议定义的端口的处理策略。
下面结合具体实施例，对上述向UE和/或UPF发送数据流的处理策略的具体实现过程进行说明。
需要说明的是，以下实施例是以处理策略信息为数据流处理策略信息(也可以称为端口数据流处理策略信息、或称为端口的数据流处理策略信息)为例进行说明的，但本申请对处理策略信息的具体实现方法进行限定。
以下图6-图8所示的实施例中，AF从TSN控制面接收5G系统交换节点的端口粒度的数据流处理策略信息。端口粒度的数据流处理策略信息是指端口在对数据流进行处理时依据的策略信息，例如，按照分配的时间片对数据流进行调度。端口粒度可以是物理端口(如物理网口或虚拟端口)，也可以逻辑端口(如PDU会话粒度端口或内部端口等)。AF将端口粒度的数据流处理策略信息发送到PCF/SMF/UPF，进而在UPF上创建端口粒度的数据流处理策略，可选的，AF还将UE侧端口粒度的数据流处理策略信息发送到UE，用于确定UE对TSN流的数据流处理策略。
需要说明的是，本申请中数据流处理策略发送至UPF，指的是发送到UPF的端口或UPF对应的TSN转换器的端口，该TSN转换器可以与UPF合一设置，也可以单独设置。本申请中数据流处理策略发送至UE，指的是发送到UE的端口或UE对应的TSN转换器的端口，该TSN转换器可以与UE合一设置，也可以单独设置。
如图6所示，为本申请提供的又一种通信方法流程示意图。该实施例中，TSN控制面将5G系统交换节点端口粒度的数据流处理策略下发到5G系统交换节点的控制面网元AF，AF接收到上述数据流处理策略后，将上述数据流处理策略发送到PCF，触发PCF进行QoS流创建或更新过程，在上述流程中将端口粒度的数据流处理策略配置到5G系统交换节点的端口，这里的端口可以是网络侧的端口，例如UPF侧端口或TSN转换器端口，也可以是UE侧端口，例如UE侧端口或TSN转换器端口。从而实现5G系统用户面对端口粒度的数据流处理策略的创建。
该方法包括以下步骤：
步骤601，CNC向AF发送5G系统交换节点上的数据流处理策略信息。相应的，AF可以接收到5G系统交换节点上的数据流处理策略信息。
该数据流处理策略信息的具体实现方式可以参考图5实施例的相关描述，这里不再赘 述。
比如，若该数据流处理策略信息是针对UE的端口的数据流处理策略信息，则该数据流处理策略信息中包含的端口的标识是UE的端口的标识或UE对应的TSN转换器的端口的标识。
再比如，若该数据流处理策略信息是针对UPF的端口的数据流处理策略信息，则该数据流处理策略信息中包含的端口的标识是UPF的端口的标识或UPF对应的TSN转换器的端口的标识。
步骤602，AF向PCF发送5G系统交换节点上的UE的会话的标识和数据流处理策略信息。相应的，PCF可以接收到5G系统交换节点上的UE的会话的标识和数据流处理策略信息。
AF从CNC接收到5G系统交换节点上的数据流处理策略信息后，获取到数据流处理策略信息中的端口的标识，进而可以根据该端口的标识确定UE的会话的标识(比如可以UE的MAC地址等)，然后向PCF发送UE的会话的标识和数据流处理策略信息。
其中，AF根据端口的标识确定UE的会话的标识的具体方式，可以参考图5实施例的相关描述，这里不再赘述。
作为一种实现方式，在该步骤602中，AF还可以向PCF发送一个第一指示信息，该第一指示信息的作用可以参考图5实施例中对第一指示信息的作用的描述，这里不再赘述。
综上所述，在实际在应用中，AF向PCF发送数据流处理策略信息的方法至少有以下两种：
方法一，AF向PCF发送5G系统交换节点上的UE的会话的标识和数据流处理策略信息。
基于该实现方法，PCF可以解析数据流处理策略信息，获取其中的端口的标识，进而确定该端口的标识对应的端口是UE的端口还是UPF的端口。
方法二，AF向PCF发送5G系统交换节点上的UE的会话的标识、数据流处理策略信息以及第一指示信息。
其中，数据流处理策略信息被AF封装成一个透明容器，PCF不能解析数据流处理策略信息，或者PCF能够解析数据流处理策略信息但不能识别数据流处理策略信息中的端口是UE的端口还是UPF的端口，则PCF可以根据第一指示信息，确定该数据流处理策略信息是UE的数据流处理策略信息还是UPF的数据流处理策略信息。
该步骤，AF可以直接发送UE的会话的标识和数据流处理策略信息到PCF，也可以是通过NEF发送UE的会话的标识和数据流处理策略信息到PCF。
步骤603，PCF发起QoS流创建/修改流程，通过QoS流创建/修改请求消息发送数据流处理策略信息到SMF。
PCF在接收到UE的会话的标识和数据流处理策略信息后，根据其中的UE的会话的标识，发起QoS流创建/修改流程，然后通过QoS流创建/修改请求消息，将数据流处理策略信息发送到SMF。
若端口的标识指示的端口是UPF的端口，则执行以下步骤604-步骤605；若端口的标识指示的端口是UE的端口，则执行以下步骤606-步骤607。
步骤604，SMF通过N4会话创建/修改请求消息发送数据流处理策略信息到UPF。
可选的，SMF还向UPF发送一个第二指示信息，用于指示该数据流处理策略信息应 用于UPF的本地端口，而不是应用于UE的会话。或者理解为，该指示信息用于指示数据流处理策略信息是端口的策略信息。
步骤605，UPF根据数据流处理策略信息，处理TSN流。
也即，UPF接收到数据流处理策略信息后，将数据流处理策略信息中的处理策略配置给端口，或者将数据流处理策略信息发送到TSN转换器，由TSN转换器配置给端口。
比如，数据流处理策略信息中包含端口的标识、数据流的优先级列表、数据流优先级对应的处理策略(例如门控信息列表)。因此，该数据流处理策略信息指示的端口按照数据流优先级对应的处理策略，来处理TSN流，例如在数据流优先级对应的时间片上发送TSN流。
步骤606，SMF发送数据流处理策略信息到UE。
比如，SMF向UE发送PDU会话修改请求消息，其中携带数据流处理策略信息，即SMF可以通过UPF向UE发送数据流处理策略信息，或者，SMF还可以通过非接入层(non access stratum，NAS)消息，向UE发送数据流处理策略信息。
可选的，SMF还向UE发送一个第二指示信息，用于指示该数据流处理策略信息应用于UE的本地端口，而不是应用于UE的会话。或者理解为，该指示信息用于指示数据流处理策略信息是端口的策略信息。
步骤607，UE根据数据流处理策略信息，处理TSN流。
也即，UE接收到数据流处理策略信息后，将数据流处理策略信息中的处理策略配置给端口，或者将数据流处理策略信息发送到TSN转换器，由TSN转换器配置给端口。
比如，数据流处理策略信息中包含端口的标识、数据流的优先级列表、数据流优先级对应的处理策略(例如门控信息列表)。因此，该数据流处理策略信息指示的端口按照数据流优先级对应的处理策略，来处理TSN流，例如在数据流优先级对应的时间片上发送TSN流。
需要说明的是，作为又一种实现方法，若AF从CNC接收到的数据流处理策略信息既包括针对UPF的端口的数据流处理策略信息，又包括针对UE的端口的数据流处理策略信息，则后续SMF可以通过类似上述步骤604-步骤605，将针对UPF的端口的数据流处理策略信息发送至UPF，以及通过上述步骤606-步骤607，将针对UE的端口的数据流处理策略信息发送至UE。
该实施例，基于现有5G管理和转发架构，实现TSN管理系统对5G系统交换节点的端口粒度的数据流处理策略的配置，从而使能5G系统交换节点支持TSN协议定义的端口粒度的数据流处理策略。
如图7所示，为本申请提供的又一种通信方法流程示意图。该实施例中，TSN控制面将5G系统交换节点端口粒度的数据流处理策略下发到5G系统交换节点的控制面网元AF，AF接收到上述数据流处理策略后，将上述数据流处理策略发送到SMF，进而SMF触发QoS流创建/修改流程，在该流程中将端口粒度的数据流处理策略配置到5G系统交换节点的端口，或者是由SMF直接向5G系统交换节点创建端口粒度的数据流处理策略。这里的端口可以是UPF的端口或TSN转换器端口，也可以是UE的端口或TSN转换器端口。从而实现5G系统用户面对端口粒度的数据流处理策略的创建。
该方法包括以下步骤：
步骤701，同图6实施例的步骤601，可参考前述描述。
步骤702，AF向SMF发送5G系统交换节点上的UE的会话的标识和数据流处理策略信息。相应的，SMF可以接收到5G系统交换节点上的UE的会话的标识和数据流处理策略信息。
该步骤中，AF可以通过用户会话向SMF发送UE的会话的标识和数据流处理策略信息。
这里的数据流处理策略信息与图6实施例的步骤602中描述的数据流处理策略信息相同，可参考前述描述。
作为一种实现方式，在该步骤702中，AF还可以向SMF发送第一指示信息，该第一指示信息的作用可以参考图5实施例中对于第一指示信息的作用的描述，这里不再赘述。
步骤703，SMF发送5G系统交换节点的UE的会话的标识和数据流处理策略信息到PCF，用于触发QoS流创建/修改流程。
该步骤中，SMF可直接将从AF接收到的携带会话的标识和数据流处理策略信息的消息转发给PCF，或者通过SMF和PCF之间定义的信元发送会话的标识和数据流处理策略信息。
可选的，若SMF在步骤702中接收到第一指示信息，则该步骤中SMF还向PCF发送该第一指示信息。
步骤704-步骤708，同图6实施例的步骤603-步骤607，可参考前述描述。
需要说明的是，上述步骤703-步骤704为可选步骤。即当执行步骤703-步骤704时，则是由SMF触发PCF发起QoS流创建/修改流程，进而实现5G系统端口粒度的数据流处理策略的创建。当不执行步骤703-步骤704时，则是由SMF直接创建5G系统端口粒度的数据流处理策略。
需要说明的是，若不执行步骤703-步骤704，则在实际在应用中，上述步骤702中，AF向SMF发送数据流处理策略信息的方法至少有以下两种：
方法一，AF向SMF发送5G系统交换节点上的UE的会话的标识和数据流处理策略信息。
基于该实现方法，SMF可以解析数据流处理策略信息，获取其中的端口的标识，进而确定该端口的标识对应的端口是UE的端口还是UPF的端口。
方法二，AF向SMF发送5G系统交换节点上的UE的会话的标识、数据流处理策略信息以及第一指示信息。
其中，数据流处理策略信息可以被AF封装成一个透明容器，SMF不能解析数据流处理策略信息，或者SMF能够解析数据流处理策略信息但不能识别数据流处理策略信息中的端口是UE的端口还是UPF的端口，则SMF可以根据第一指示信息，确定该数据流处理策略信息是UE的数据流处理策略信息还是UPF的数据流处理策略信息。进而根据UE的会话的标识，确定UE或确定UPF。
需要说明的是，作为又一种实现方法，若AF从CNC接收到的数据流处理策略信息既包括针对UPF的端口的数据流处理策略信息，又包括针对UE的端口的数据流处理策略信息，则后续SMF可以通过类似上述步骤705-步骤706，将针对UPF的端口的数据流处理策略信息发送至UPF，以及通过类似上述步骤707-步骤708，将针对UE的端口的数据流处理策略信息发送至UE。
作为一种可替代的实现方案，若步骤701的数据流处理策略信息是针对UPF的端口的数据流处理策略信息，则上述步骤702中，AF也可以不通过会话的方式向SMF发送UE的会话的标识和数据流处理策略信息。比如，AF可以根据5G系统交换节点与SMF的对应关系(或UPF与SMF的对应关系)，或者根据端口的标识与SMF的对应关系，确定SMF，然后直接向该SMF发送数据流处理策略信息，此时不需要执行上述步骤703、步骤704，然后SMF直接将该数据流处理策略信息发送给与该SMF对应的UPF(比如可以通过设备粒度的接口向UPF发送数据流处理策略信息)，该UPF然后执行步骤706。此时步骤707和步骤708也不需要执行。
该实施例，基于现有5G管理和转发架构，实现TSN管理系统对5G系统交换节点的端口粒度的数据流处理策略的配置，从而使能5G系统交换节点支持TSN协议定义的端口粒度的数据流处理策略。
如图8所示，为本申请提供的又一种通信方法流程示意图。该实施例中，TSN控制面将5G系统交换节点端口粒度的数据流处理策略下发到5G系统交换节点的控制面网元AF，AF接收到上述数据流处理策略后，将上述数据流处理策略发送到UPF，若该数据流处理策略是针对UPF的端口的数据流处理策略，则UPF直接创建端口粒度的数据流处理策略(对应步骤803)；若该数据流处理策略是针对UE的端口的数据流处理策略，则UPF通过用户面发送针对UE的端口的数据流处理策略，从而UE创建端口粒度的数据流处理策略(对应步骤804-步骤805)。从而实现5G系统对端口粒度的数据流处理策略的创建。
该方法包括以下步骤：
步骤801，同图7实施例的步骤701。
步骤802，AF发送5G系统交换节点的数据流处理策略信息到UPF。
这里的数据流处理策略信息可以是针对UPF的端口的数据流处理策略信息，也可以是针对UE的端口的数据流处理策略信息。
UPF接收到数据流处理策略信息后，可以解析该数据流处理策略信息，获取其中的端口的标识，并识别该端口是UE的端口还是UPF的端口。若该端口是UPF的端口，则执行步骤803，若该端口是UE的端口，则执行步骤804-步骤805。
步骤803，同图7实施例的步骤706，可参考前述描述。
步骤804-步骤805，同图7实施例的步骤707-步骤708，可参考前述描述。
需要说明的是，作为又一种实现方法，若AF从CNC接收到的数据流处理策略信息既包括针对UPF的端口的数据流处理策略信息，又包括针对UE的端口的数据流处理策略信息，则后续UPF可以通过类似上述步骤803的方式配置数据流处理策略，以及通过类似上述步骤804-步骤805的方式，配置UE的数据流处理策略。
需要说明的是，若上述数据流处理策略信息是针对UE的端口的数据流处理策略信息，则上述步骤802中，AF也可以向UPF发送UE的会话的标识和数据流处理策略信息，其中AF生成UE的会话的标识的具体方式可以参考图6实施例的相关描述。从而，UPF在接收到UE的会话的标识和数据流处理策略信息后，可以根据UE的会话的标识确定UE，然后向该UE直接发送数据流处理策略信息，此时UPF无需解析数据流处理策略信息。或者是，UPF在接收到UE的会话的标识和数据流处理策略信息后，将UE的会话的标识和数据流处理策略信息发送至SMF，然后SMF可以按照图7所示的实施例的方法，将数据 流处理策略信息配置到UE，比如SMF通过NAS消息数据流处理策略信息配置到UE。
该实施例，基于现有5G管理和转发架构，实现TSN管理系统对5G系统交换节点的端口粒度的数据流处理策略的配置，从而使能5G系统交换节点支持TSN协议定义的端口粒度的数据流处理策略。
