具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
为了便于理解本申请提供的方案，下面对于本申请涉及的一些技术用于进行介绍。
1、业务控制器：在内部存储执行逻辑运算、顺序控制、定时、计数和算术运算等操作的指令，通过数字式或模拟式的输入输出来控制各种类型的机械设备或生产过程。例如，接收来自业务控制器的远控台的业务控制报文，并根据该业务报文控制机械设备(例如机械臂)或生产过程。例如，业务控制器可以是PLC，或者也可以是其他具备类似功能的设备。其中，PLC为一种专门为在工业环境下应用而设计的数字运算操作电子系统。它采用一种可编程的存储器，在内部存储上述操作的指令。
2、业务控制器的远控台：业务控制器的远控台通过网络向业务控制器的发送业务控制报文，通过该业务控制报文指示该业务控制器对机械设备或生成过程进行控制。相应地，业务控制器通过网络向业务控制器的远控台进行状态上报。从而，实现业务控制器的远控台对业务控制器的远程控制。例如，业务控制器为PLC，业务控制器的远控台为PLC的远控台。
3、用户驻地设备(customer premises equipment，CPE)：一种接收移动信号(如5G信号)并通过有线端口(例如以太网接口或通用串行总线端口等)转发出去的移动信号接入设备。
4、工业交换机：工业交换机主要用于在复杂的工业环境中的实现实时以太网数据传输。工业交换机采用存储转换交换方式，同时提高以太网通信速度，并且内置智能报警设计监控网络运行状况，使得在恶劣危险的工业环境中保证以太网可靠稳定的运行。
5、控制室交换机：用于PLC远控台与通信网络之间的信息交互。
6、核心网：主要用于提供用户连接、对用户的管理以及对业务完成承载，作为承载网络提供到外部网络的接口。以5G核心网为例，其包括控制面设备和用户面设备。其中，控制面设备包括接入和移动性管理功能实体、会话管理功能实体、网络能力开放实体、网络数据分析实体等。用户面设备例如可以是用户面功能实体。本申请涉及用户面功能实体(user plane function，UPF)，负责用户的数据转发、计费统计等。
7、PROFINET：是由PROFIBUS国际组织(PROFIBUS International，PI)推出的新一代基于工业以太网技术的自动化总线标准。PROFINET为自动化通信领域提供了一个完整的网络解决方案，囊括了诸如实时以太网、运动控制、分布式自动化、第一故障安全以及网络安全等当前自动化领域的热点话题，并且，作为跨供应商的技术，可以完全兼容工业以太网和现有的现场总线(如过程现场总线(process field bus，PROFIBUS))技术，保护现有投资。
目前，5G已经融入千行百业，为千行百业创造新价值。为了满足很多5G ToB的场景对报文(例如业务报文)传输的高可靠性的要求，会对需要传输的报文进行复制后通过双链路传输。
图1是本申请实施例提供的传输系统的交互流程图，其中，UPF1和CPE1构成A链路，UPF2和CPE2构成B链路。
如图1中的(a)所示，PLC向PLC远控台发送上行报文时，上行报文经双发选收设备复制转发后，分别接入CPE1和CPE2，随后CPE1通过空口通信将上行报文传输到UPF1，并且UPF1将上行报文传输到UPF2，CPE2通过空口通信将上行报文传输到UPF2，并且UPF2将上行报文传输到UPF1，随后由UPF1将上行报文发送给交换机，到达远控台。
如图1中的(b)所示，PLC远控台发送的下行报文经交换机后发送给UPF1，UPF1将下行报文复制后，分别发送给CPE1和UPF2，UPE2将下行报文转发给CPE2，CPE1和CPE2将下行报文经双发选收设备处理后发送给PLC。
其中，双发选收设备可以在传输上行报文时对上行报文进行复制转发实现双发功能，在传输下行报文时对来自CPE1和CPE2的下行报文进行去重处理，实现选发功能，示例性地，双发选收设备可以是AR交换机、工业交换机或工业网关。
上述方案中，UPF1被称为主UPF，UPF2被称为从UPF或辅UPF。在传输上行报文时，UPF1接收来自UPF2和CPE1的上行报文，经过去重操作后发送给交换机，起到选发的作用；在传输下行报文时，UPF1对来自交换机的下行报文进行复制，并分别转发给UPF2和CPE1，起到双发的作用。
在本申请实施例中，UPF1和UPF2可以基于业务进行自动同步，UPF1、UPF2之间同步静态配置数据，保持双发选收协议定时器时长的一致性。在执行双发功能时，双发端维持一个序号counter，并在给A、B两路的复制报文添加冗余控制标签(redundancy control tag，RCT)时保持每一路报文序号的连续性。在执行选收功能时，选收端正常发送先到的正常顺序报文并丢弃后续重复报文；若出现缺失报文，则对 先到的报文进行缓存排序，等其他链路相同序号的报文到达后按照顺序发送报文，因此需要使用缓冲区保存已收到报文的序号、乱序到达的报文。进一步地，UPF2在接收到来自UPF1的报文后，保存该报文中的序号和时间戳，用于实现基于业务流的自动同步。
具体地，上行传输场景下，如果A路先到达UPF1，则UPF1将去掉RCT的A路报文转发给交换机，将携带有RCT和到达时间戳的A路报文转发给UPF2；UPF1记录A路报文序号，后续收到B路该序号的报文直接丢弃，UPF2记录A路报文序号和时间戳，后续收到B路该序号报文，在正常场景下仍然给UPF1转发。上行传输场景下，交换机发送报文到UPF1，UPF1复制为A、B两路，UPF1通过B路向UPF2发送带RCT序号的报文，UPF2记录B路报文序号。
两个UPF在正常情况下1主1从协同工作，因此UPF1、UPF2都需要在设备启动后，初始化各自的主/从角色。以双发选收设备为工业网关为例，具体地，上行首包在端侧工业网关复制为A路、B路，A/B路信息在RCT中携带，UPF解析RCT，收到A路报文的UPF为主UPF，收到B路为从UPF；下行首包未知单播报文不双发，各UPF按原方式发送(泛洪或丢弃)，因此下行首包不需要区分主/从，下行后续报文根据上行首包确定的主/从UPF处理。
基于上述方案，在端到端的报文传输过程中，主UPF承担了一端的双发选收功能，可以避免在两端都额外布置双发选收设备，减少了线路部署和人工调配的成本，也降低了对设备部署和网络配置的依赖。
上述方案描述的是未发生第一故障时报文传输的流程，图2是本申请实施例提供的报文传输方法200的流程示意图，其中，方法200用于在发生第一故障后，实现报文的正常传输。
S201，第二通信模块确定报文传输系统发生第一故障，其中，第二通信模块与第一通信模块属于同一报文传输系统，第一通信模块可以接收来自报文发送端的报文并分别转发给第二通信模块和报文接收端，第一故障指的是与第一通信模块相关的故障。
在一种可能的实现方式中，第一通信模块和第二通信模块分别是两个用户面功能UPF设备，或者，第一通信模块和第二通信模块分别是一个UPF设备中的两个内部通信模块，示例性地，第一通信模块是上述图1中的UPF1，第二通信模块是上述图1中的UPF2。
其中，第一通信模块和第二通信模块之间存在通信链路，该通信链路用于两个通信模块之间相互转发业务报文。第一通信模块和第二通信模块还可以通过以太网聚合Eth-Trunk进行链路捆绑，从而增强第一通信模块和第二通信模块之间通信链路的可靠性。
在一种可能的实现方式中，第二通信模块接收来自第一通信模块的报文后，保存该报文中携带的序号和时间戳。
本申请实施例中，第二通信模块可以确定报文传输系统是否发生第一故障，本申请实施例中报文传输系统的第一故障包括：第一通信模块发生第一故障、第一通信模块与报文发送端之间的链路发生第一故障、第一通信模块与第二通信模块之间的链路发生第一故障和第一通信模块与报文接收端之间的链路发生第一故障。
在一种可能的实现方式中，第二通信模块接收来自检测系统的第一指示信息，第一指示信息用于指示报文传输系统发生第一故障，检测系统用于检测报文传输系统是否发生故障。
示例性地，检测系统可以通过双向转发检测(bidirectional forwarding detection，BFD)检测机制检测报文传输系统中各个链路是否发生第一故障。
BFD是一种用于链路故障检测的协议。BFD与相邻系统建立会话后，在它们之间的通道上周期性地发送BFD包，如果某个系统在协商的检测时间内没有接收到BFD包，则认为这条双向通道的某个部分出了故障。上层协议通过BFD感知到链路故障后可以及时采取措施，进行故障恢复。
在一种可能的实现方式中，第二通信模块在接收到来自第一通信模块的报文后启动定时器，若在第一时间段内未收到下一个来自第一通信模块的报文，则确定报文传输系统发生第一故障。
其中，第一时间段是预先设定的时间段，具体地，第一时间段大于报文的周期，小于业务容忍时间(survival time)。
上述方案中的报文是周期性报文，由于正常传输报文时，第一通信模块会在接收到来自报文发送端的报文后转发给第二通信模块，因此当第二通信模块无法在第一时间段内接收下一个周期的报文时，可以判定报文传输系统发生了第一故障。特别地，若第一故障原因是第一通信模块与报文接收端之间的链路发生故障，则在一种可能的实现方式中，第一通信模块识别出第一故障后主动停止向第二通信模块转发报文，从而使得第二通信模块确定报文传输系统发生第一故障；在另一种可能的实现方式中，第一通 信模块识别出第一故障后向第二通信模块发送指示信息，该指示信息用于指示报文传输系统发生第一故障。
进一步地，可以通过检测乒乓切换，检测到之后利用多个终端、多个业务流的故障检测结果，综合判断，避免单业务流易受空口随机性的影响。
S202，第二通信模块获取来自报文发送端的第一报文。
对于上行传输报文，由于报文发送端会向第二通信模块发送上行传输报文，因此第二通信模块直接获取第一报文。
对于下行传输报文，第二通信模块向报文发送端发送第一请求信息，第一请求信息用于请求接收报文，基于第一请求信息，第二通信模块接收来自报文发送端的第一报文。
在一种可能的实现方式中，第一请求信息包括以下至少一项：第一上行报文、第一路由信息和包含第一地址信息的地址解析协议ARP报文，其中，第一上行报文是第二通信模块接收到的上行报文或构造的上行报文，第一路由信息是第一终端设备的路由信息，第一终端设备是所述报文接收端服务的终端设备，第一地址信息用于指示第一终端设备的地址。
示例性地，若业务是5G LAN业务，则第一地址信息是第一终端设备的MAC地址，若业务不是5G LAN业务，则第一路由信息是第一终端设备的IP路由。
S203，第二通信模块向报文接收端发送第一报文。
第一报文包括第一序号，第一序号用于表示报文发送顺序，示例性地，第一序号是双发报文时维持的序号counter，在给A、B两路的复制报文添加RCT时保持每一路报文序号的连续性，A路指的是第一通信模块所在的链路，B路是指的是第二通信模块所在的链路。
第一报文的第一序号大于第二报文的序号，第二报文是报文传输系统第一故障前第二通信模块接收的来自第一通信模块的报文，从而避免向报文接收端发送重复报文。
在一种可能的实现方式中，第二通信模块接收到来自第一通信模块的报文后，保存该报文中携带的第一序号和/或时间戳。
具体地，在发生第一故障后，若第二通信模块收到序号与已保存的第一序号相同的报文，则直接丢弃。
本申请实施例中，在报文传输系统发生第一故障时，由第二通信模块继续转发报文，确保第一故障时报文的转发，实现报文的高可靠性传输。
应理解，上述方案描述的是图1中报文传输系统出现第一故障时的报文传输方法，若第一故障恢复，则UPF2需要和UPF1进行缓存同步，然后按报文传输系统第一故障前的模式继续传输报文。若上述报文传输系统未发生第一故障，则在传输上行报文时，第二通信模块向第一通信模块发送来自报文发送端的第三报文，第二通信模块接收来自第一通信模块的第四报文，第三报文是第四报文的备份，第四报文是报文发送端发送给第一通信模块的报文；在传输下行报文时，第二通信模块接收来自第一通信模块发送的第五报文并转发给报文接收端，第五报文是第六报文的备份，第六报文是报文发送端发送给第一通信模块的报文。
上述方案中的缓存同步可以是一次性全量同步双发选收缓存或周期性同步UPF1和UPF2的缓冲区数据，使用一次性全量同步双发选收缓存可以避免超过容忍时间。
本申请实施例中，若UPF2检测到UPF之间链路长时间中断，则周期性查询第三方，确认UPF1的状态，直到UPF间链路恢复结束，如果UPF1状态正常，则UPF2不再继续转发上行报文到报文接收端。通过该方法避免报文接收端接收到完全相同的重复报文，提高性能和处理效率。
需要说明的是，本申请实施例中报文接收端和报文发送端是功能性的描述，示例性地，在上行过程中，报文发送端指的是工业网关，报文接收端指的是交换机；在下行过程中，报文发送端指的是交换机，报文接收端指的是工业网关。此外，报文接收端和报文发送端通过CPE与第一通信模块和第二通信模块传输报文。
下面结合图3和图4，以第一通信模块为UPF1，第二通信模块为UPF2为例，分别介绍第二通信模块在报文传输系统发生第一故障后如何保证正常传输上行报文和下行报文，为便于描述，将通过第一通信模块传输报文的链路称为A路，将通过第二通信模块传输报文的链路称为B路。
图3是本申请实施例提供的报文传输的方法300的示意性流程，该方法300传输的是上行报文。
S301，接收B路报文，B路报文是PLC发送给工业网关、工业网关复制后通过CPE2发送给UPF2的报 文。
S302，判断报文传输系统是否发生第一故障，若发生第一故障，则执行S303；若未发生第一故障，则执行S305。具体地，如何判断报文传输系统是否发生第一故障参见本申请实施例方法200中的步骤S201，在此不做赘述。
S303，接收来自UPF1的A路报文并向UPF1转发B路报文。
S304，判断B路报文是否为PLC报文，若是，则执行S305；若不是，则结束。
示例性地，UPF2可以根据B路报文的协议包头和内容中的至少一个进行上述判断。例如，B路报文的协议包头可以包括以太网报文类型的字段、协议类型的字段或VLAN ID的字段等。例如，这里的协议类型的字段可以是用于指示使用PROFINET的字段；再例如，这里的VLAN ID根据ID的不同可以对应于不同的场景。比如，当B路报文的以太网报文类型的字段为0x8892时，可以确定B路报文为PLC业务报文，当B路报文的以太网报文类型的字段不是0x8892时，可以确定B路报文不是PLC业务报文。再比如，当B路报文的VLAN ID为10时，可以确定B路报文为PLC业务报文，当B路报文的VLAN ID为01时，可以确定B路报文不是PLC业务报文。又比如，当B路报文的内容为机械臂的翻转或喷漆业务时，可以确定B路报文为PLC业务报文，否则，则不是PLC业务报文。
示例性地，UPF2可以预配置与PLC业务报文对应的配置信息，该配置信息中可以包括与业务报文的协议包头和内容相关的字段，当UPF2确定B路报文的协议包头和内容相关的字段与配置信息对应时，可以确定B路报文为PLC业务报文。
S305，向交换机发送B路报文。
上述方案，通过UPF2在报文传输系统发生第一故障时，代替UPF1向交换机发送上行报文，避免造成业务中断，实现报文的高可靠性传输。
图4是本申请实施例提供的报文传输方法400的示意性流程，该方法400传输的是上行报文。
S401，判断报文传输系统是否发生第一故障，若发生第一故障，则执行S402；若未发生第一故障，则执行S403。具体地，如何判断报文传输系统是否发生第一故障参见本申请实施例方法200中的步骤S201，在此不做赘述。
S402，接收来自UPF1的B路报文，B路报文是UPF1将PLC远控台通过交换机发送的下行报文复制得到的。
S403，向交换机请求B路报文，具体地请求方式参见本申请实施例方法200中的步骤S202，在此不做赘述。
S404，接收来自交换机的B路报文。
S405，判断B路报文是否为PLC报文，具体判断方法参见方法300中步骤S304。若是PLC报文，则执行步骤S406；若不是PLC报文，则流程结束。
S406，向CPE2发送B路报文，CPE2将B路转发给工业网关，工业网关转发给PLC。
上述方案，通过UPF2在报文传输系统发生第一故障时请求下行报文并代替UPF1向发送下行报文，避免造成业务中断，实现报文的高可靠性传输。
