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、无线接入网(radio access network，RAN)是指具备无线接入网的功能网元，主要负责无线接入控制，无线资源分配等功能。其中，无线网络的网元可以只包括gNB、也可以包括集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，还可以包括集中单元控制面(centralized unit-control plane，CU-CP)、集中单元用户面(centralized unit-user plane，CU-UP)。
8、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、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。一种实现方式是在端到端设备之间部署交换机，并依赖交换机对报文进行复制和去重。下面以PLC和PLC远控台之间进行业务报文的端到端交互为例，介绍该实现方式。
图1中的(a)和(b)示出了PLC和PLC远控台之间进行报文的交互的流程。如图1中的(a)所示，PLC向PLC远控台发送上行报文时，上行报文经交换机复制转发后，分别接入CPE1和CPE2，随后CPE1和CPE2分别通过空口通信将上行报文传输到5G核心网，随后由UPF将上行报文发送给控制室交换机，到达远控台。如图1中的(b)所示，PLC远控台发送的报文经控制室交换机和4G核心网之后，通过空口向CPE1和CPE2发送，再经工业交换机处理后发送给PLC。
上述实现方式要实现报文的双链路传输，需要依赖于端到端之间的设备的部署以及网络的配置，例如需要配置由工业交换机、需要考虑到网线的布置等，使得部署成本高，不利于5G ToB领域的业务快速部署。
下面结合图2至图7介绍本申请提供的报文传输的方法。
应理解，本申请中的第一终端通信模块和第二终端通信模块可以是对报文传输有高可靠性需求的两个模块；第一终端通信模块和第二终端通信模块可以是两个不同的设备(如用户驻地设备)，也可以是一个设备中的两个内部通信模块(例如芯片)。第一终端通信模块和第二终端通信模块可以是具备完全相同的能力的两个设备或两个内部通信模块，或者说，第二终端通信模块也具备本申请中第一终端通信模块具备的能力，只是在本申请提供的报文传输的方法中，第二终端通信模块可以不激活相关功能。在具体实现中，例如，有通信模块1和通信模块2互联，且通信模块1和通信模块2与第一终端通信模块具备相同的能力。该两个通信模块中的通信模块1与业务控制器互联，且激活了该通信模块1的相关功能，没有激活通信模块2的功能，那么就可以将该通信模块1作为第一终端通信模块，该通信模块2作为第二终端通信模块。

S123，当第二报文和第三报文重复时，第一终端通信模块通过第一有线连接向第一设备发送第二报文和第三报文中的一个，相应地，第一设备通过第一有线连接接收来自第一终端通信模块的第二报文和第三报文中的一个。
示例性地，当第二报文和第三报文重复时，第一终端通信模块通过第一有线连接向第一设备发送第二报文和第三报文中更早接收到的一个；以及，丢弃第二报文和第三报文中更晚接收到的一个。
结合S121-S123，可以理解的是，第一终端通信模块还用于为第一设备提供无线选收功能，第二终端通信模块将从第一设备的对端设备接收的第三报文发送给第一终端通信模块，由第一终端通信模块对第二报文或第三报文进行去重，如果第二报文和第三报文重复，则将第二报文和第三报文中的一个报文发送给第一设备的对端设备。

本申请实施例，能够减少依赖交换机实现端到端设备之间报文的双发选收，降低对设备部署和网络配置的依赖，降低成本，有利于快速的业务部署。
以上，介绍了本申请提供的报文传输的方法110和120，下文结合图3至图7，以PLC和PLC远控台之间的端到端交互为例，介绍本申请提供的报文传输的方法。
下面结合图3，以上述第一设备和第一设备的对端设备分别为PLC和PLC远控台为例、以第一终端通信模块和第二终端通信模块分别为两个CPE(CPE1和CPE2)为例介绍方法200。
图3示出了本申请提供的报文传输的方法200的示意性交互图。方法200中，上行报文经单网口接入CPE1，在CPE1内进行报文识别和复制。CPE1将复制后的报文转发给 CPE2后，分别在两个CPE内进行正常的5G局域网(local area network，LAN)转发即可，实现双发选收。CPE2通过空口接收下行报文后，转发给CPE1，由CPE1进行去重处理。
如图3中的(a)所示，PLC向PLC远控台实现上行报文的双发。PLC向CPE1发送上行报文，CPE1一方面识别并复制该报文，将复制后的报文发送给CPE2，另一方面通过空口将该报文发送给RAN。CPE2从CPE1接收到该报文后，通过空口将该报文发送给RAN。该报文经5G核心网传输后通过UPF发送给控制室交换机，再由控制室交换机发送给PLC远控台。
如图3中的(b)所示，PLC远控台向PLC通过双链路发送下行报文。PLC远控台向控制室交换机发送下行报文，控制室交换机将该报文发送给UPF，后经5G核心网传输，该报文由RAN通过空口向CPE1和CPE2发送。如果CPE2接收到该报文，会将该报文发送给CPE1。CPE1可能从RAN和/或CPE2接收到该报文。如果CPE1接收到两份该报文，会进行去重处理。随后CPE1将该报文发送给PLC。
需要说明的是，方法200以PLC和PLC远控台为例进行介绍并不对第一设备和对端设备的保护范围造成限定，以CPE1和CPE2为例进行介绍也不对第一终端通信模块或第二终端通信模块的保护范围造成限定。再具体实现中，CPE1和CPE2执行相应功能也可以由一个设备的两个芯片分别执行。
应理解，方法200通过CPE1实现报文的复制和去重，可以减少依赖工业交换机实现PLC与PLC远控台之间的报文的双发选收，或者说，方法200可以在没有配置工业交换机(或者具有类似功能的设备)的场景下实现报文的双发选收，降低了对设备部署和网络配置(或者，场景)的依赖和部署成本。
还应理解，一方面，由于PLC可以减少依赖工业交换机对报文进行复制和去重，而是由CPE提供相应的功能，减少了工业交换机的线路部署和人工调配的成本。另一方面，方法200中的网络部署可以通过CPE灵活地为多个PLC提供无线服务，进一步降低了重新部署线路和人工调配的成本。
本申请实施例，可以在高可靠性地传输报文的同时，降低对设备部署的依赖和部署成本，以便于业务的快速部署。
以上，介绍了本申请提供的报文传输的方法200，下面结合图4以上述第一设备和对端设备分别为PLC和PLC远控台为例，以第一终端通信模块和第二终端通信模块分别为CPE1和CPE2，以及第一终端通信模块分别为CPE3和CPE4为例介绍方法300。
图4示出了本申请提供的报文传输的方法300的示意性交互图。方法300在方法200的基础上，进一步减少了对设备部署的依赖，从而更加灵活地适用于不同的场景。
下面结合图4以双端无线场景为例进行说明。在该场景中，PLC和PLC远控台都减少依赖交换机进行报文传输。PLC和PLC远控台的之间的双向交互业务报文分别在各自接入的用户设备组(user equipment group，UEG)内完成上行复制和下行去重，从而提升空口可靠性。如图所示，PLC侧的UEG为CPE1和CPE2，PLC远控台侧的UEG为CPE3和CPE4。其中，UEG的物理形态可以是单设备双芯片模式，或者双设备互联模式。
如图4中的(a)所示，PLC向PLC远控台实现上行报文的双发。PLC向CPE1发送上行报文，CPE1一方面识别并复制该报文，将复制后的报文发送给CPE2，另一方面通过空口将该报文发送给RAN。CPE2从CPE1接收到该报文后，通过空口将该报文发送给 RAN1。该报文经5G核心网传输后，由RAN2通过空口发送给CPE3和CPE4。如果CPE4接收到该报文，会将该报文发送给CPE3。CPE3可能从RAN和/或CPE4接收到该报文。如果CPE1接收到两份该报文，会进行去重处理。随后CPE1将该报文发送给PLC远控台。
如图4中的(b)所示，PLC远控台向PLC通过双链路发送下行报文。PLC远控台向CPE3发送下行报文，CPE3一方面识别并复制该报文，将复制后的报文发送给CPE4，另一方面通过空口将该报文发送给RAN2。后经5G核心网传输，该报文由RAN1通过空口向CPE1和CPE2发送。如果CPE2接收到该报文，会将该报文发送给CPE1。CPE1可能从RAN1和/或CPE2接收到该报文。如果CPE1接收到两份该报文，会进行去重处理。随后CPE1将该报文发送给PLC。
需要说明的是，方法300以PLC和PLC远控台为例进行介绍并不对第一设备和对端设备的保护范围造成限定，以CPE1和CPE2、CPE3和CPE4为例进行介绍也不对第一终端通信模块或第二终端通信模块的保护范围造成限定。再具体实现中，CPE1和CPE2执行相应功能也可以由一个设备的两个芯片分别执行，CPE3和CPE4执行相应功能也可以由一个设备的两个芯片分别执行。
应理解，方法300通过CPE1实现报文的复制和去重，可以减少依赖工业交换机和控制室交换机实现PLC与PLC远控台之间的报文的双发选收，或者说，方法200可以在没有配置工业交换机和/或控制室交换机(或者具有类似功能的设备)的场景下实现报文的双发选收，降低了对设备部署(或者，场景)的依赖和部署成本。
还应理解，一方面，由于PLC可以减少依赖工业交换机和控制室交换机对报文进行复制和去重，而是由CPE提供相应的功能，减少了工业交换机的线路部署和人工调配的成本。另一方面，方法300中的网络部署可以通过CPE灵活地为多个PLC提供无线服务，以及通过CPE灵活地为多个PLC远控台提供无线服务，进一步降低了重新部署线路和人工调配的成本。
本申请实施例，可以在高可靠性地传输报文的同时，降低对设备部署的依赖和部署成本，以便于业务的快速部署。
以上介绍了本申请提供的报文传输的方法300。下面结合图5分别介绍本申请提供的第一终端通信模块和第二终端通信模块在图3或图4所示的应用场景中的实现方式。其中，以第一终端通信模块为CPE1，第二终端通信模块为CPE2为例进行介绍，但该示例对本申请的第一终端通信模块和第二终端通信模块的保护范围并不造成限定，例如第一终端通信模块和第二终端通信模块的物理形态还可以是单设备双芯片。类似的，CPE3也可以实现与CPE1类似的功能，CPE4也可以实现与CPE2类似的功能，本申请对此不多赘述。
图5示出了本申请提供的第一终端通信模块和第二终端通信模块的实现方式。CPE1与CPE2之间通过互联端口进行报文的传输，该互联端口可以是GMAC端口、高速串行计算机扩展总线标准(peripheral component interconnect express，PCI-Express)端口或者USB端口，或者还可以是能够用于CPE1与CPE2之间传输报文其他端口，本申请对此不做限定。
为了便于理解本申请提供的方案，可以将图5中的(a)与图3中的(a)或图4中的(a)来理解第一终端通信模块和第二终端通信模块的实现方式；可以将图5中的(b)与图3中的(b)或图4中的(b)来理解第一终端通信模块和第二终端通信模块的实现方式。
如图5中的(a)所示，PLC通过GMAC端口向CPE1发送报文(例如业务报文)，CPE1从GMAC端口接收报文后，将该报文上送至转发模块。转发模块将该报文转发至5G协议栈。5G协议栈通过空口将该报文转发出去。转发模块对该报文进行复制，并将复制后的报文通过互联端口发送给CPE2。CPE2通过互联端口接收到该报文，将该报文上送至转发模块。转发模块将该报文转发至5G协议栈。5G协议栈通过空口将该报文转发出去。
如图5中的(b)所示，CPE1可以从空口和/或互联端口接收到报文。其中，CPE1通过5G协议栈从空口接收报文，并将该报文上送到转发模块；CPE1通过互联端口接收来自CPE2的报文。如果CPE1从空口和互联端口接收到该报文，将会进行去重处理，将去重处理后的报文通过GMAC端口发送给PLC；如果CPE1从空口或互联端口接收到该报文，将接收到的报文通过GMAC端口发送给PLC。如果CPE1从互联端口接收到该报文，相应地，CPE2从空口接收到该报文，5G协议栈将该报文发送至转发模块，该转发模块通过互联端口将该报文发送给CPE1。
需要说明的是，CPE1的转发模块可以通过硬件或软件的方式实现，例如该转发模块可以是具备复制和去重功能的硬件以太网转发模块。
需要说明的是，CPE1和CPE2具备的能力可以是相同的，也可以是不同的。例如，CPE1和CPE2具备的能力相同的情况下，CPE1和CPE2的端口数量和类型一致，即CPE2具备互联端口外，至少还具备一个GMAC端口，但该GMAC端口未从PLC接收报文；CPE1和CPE2的转发模块都具备对报文进行复制和去重的能力，但CPE2的转发模块未激活相关功能(例如，CPE2可以根据未与PLC连接确定不激活转发模块的对报文进行复制和去重的功能)。
本申请实施例，通过增加CPE1和CPE2之间的互联端口，实现CPE1和CPE2之间的报文传输，通过增强CPE对报文进行复制和去重的能力，实现PLC与PLC远控台之间的报文传输的双发选收，提高空口传输的可靠性。并且，可以在高可靠性地传输报文的同时，降低对设备部署的依赖和部署成本，以便于业务的快速部署。
以上，介绍了本申请提供的第一终端通信模块和第二终端通信模块的实现方式。下面结合图6和图7，以第一终端通信模块为CPE1，第二终端通信模块为CPE2为例，分别介绍第一终端通信模块如何对报文进行复制和去重。

示例性地，转发模块可以根据该业务报文的协议包头和内容中的至少一个进行上述判断。例如，该业务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，当该业务报文的以太网报文类型的字段为0x8892时，可以确定该业务报文为PLC业务报文，当该业务报文的以太网报文类型的字段不是0x8892时，可以确定该业务报文不是PLC业务报文。再比如，当该业务报文的VLAN ID为10时，可以确定该业务报文为PLC业务报文，当该业务报文的VLAN ID为01时，可以确定该业务报文不是PLC业务报文。又比如，当该业务报文的内容为机械臂的翻转或喷漆业务时，可以确定该业务报文为PLC业务报文，否则，则不是PLC业务报文。
示例性地，转发模块可以预配置与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，当转发模块确定该业务报文的协议包头和内容相关的字段与配置信息对应时，可以确定该业务报文为PLC业务报文。

示例性地，转发模块可以根据该业务报文的协议包头和内容中的至少一个进行上述判断。该业务报文的协议包头可以包括以太网包头的报文类型字段、协议类型字段和VLAN ID的字段等。比如，当该业务报文的VLAN ID为10时，可以确定该业务报文需要被复制，当该业务报文的VLAN ID为01时，可以确定该业务报文不需要被复制。
示例性地，转发模块可以预配置用于确定是否复制该业务报文的配置信息，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，当转发模块确定该业务报文的协议包头和内容相关的字段与配置信息对应时，可以确定复制该业务报文。
S405，转发模块复制该业务报文。
S406，CPE1通过互联端口向CPE2发送该业务报文，相应地，CPE2从互联端口接收该业务报文。
上述方案，通过CPE1将从PLC接收的报文转发至空口，以及对该报文进行复制并转发给CPE2，再由CPE2转发至空口，使得CPE1和CPE2可以为PLC提供无线双发功能，实现该报文的备份发送，提高业务报文传输的高可靠性。其中，通过在两个CPE之间设置互联端口，实现该两个CPE之间的报文传输，从而报文的备份发送，相对于使用工业交换机提供类似的功能，可以降低PLC与PLC远控台的端到端传输对设备部署的依赖和网络部署成本，以便于系统的灵活、快速部署。

S508，向GMAC端口转发该业务报文，或者，通过GMAC端口向PLC转发该业务报文。
S504，转发模块判断是否对该业务报文进行去重。如果判断结果为否，则执行S508；如果判断结果为是，则进行步骤S505。
示例性地，转发模块可以根据该业务报文的协议包头和内容中的至少一个进行上述判断。例如，该业务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，当该业务报文的以太网报文类型的字段为0x8892时，可以确定需要对该业务报文进行去重处理，当该业务报文的以太网报文类型的字段不是0x8892时，可以确定不需要对该业务报文进行去重处理。再比如，当该业务报文的VLAN ID为10时，可以确定需要对该业务报文进行去重处理，当该业务报文的VLAN ID为01时，可以确定不需要对该业务报文进行去重处理。又比如，当该业务报文的内容为机械臂的翻转或喷漆业务时，可以确定需要对该业务报文进行去重处理，否则，则不需要。
示例性地，转发模块可以预配置用于确定是否对该业务报文进行去重的配置信息，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，当转发模块确定该业务报文的协议包头和内容相关的字段与配置信息对应时，可以确定对该业务报文进行去重。
下面对S505进行介绍，S508参考上述描述。
S505，转发模块判断定时器窗口内，是否已收到PLC业务报文。如果判断结果为否，则执行S507，随后执行S508；如果判断结果为是，则进行步骤S506。
或者，S505也可以理解为，转发模块判断该业务报文是否是定时器窗口内接收到的第一个PLC业务报文，或者，转发模块判断在接收到该业务报文之前，是否已经接收到与该业务报文重复的PLC业务报文。示例性地，这里的“重复”可以参照方法120中“第二报文和第三报文重复”对应的描述，在此不多赘述。
下面给出具体示例，用于说明S505中转发模块如何进行判断、对应的S506和S507如何执行。
作为一个示例，S505，定时器窗口内，转发模块可以根据本地记录的信息判断是否已收到PLC业务报文。例如，该本地记录的信息可以是一个状态位，当该状态位为0时，表示定时器窗口内未收到PLC业务报文，那么后续执行S507；当该状态位为1时，表示定时器窗口内已收到PLC业务报文，那么后续执行S506。
S506，丢弃该业务报文。
S507，记录已收到PLC业务报文。示例性地，与S505的示例对应，S507这里可以是将状态为设为1。
作为另一个示例，S505’，转发模块可以根据接收到的报文本身的序列号判断是否已收到PLC业务报文。例如，转发模块根据本地是否记录着与接收到的报文的序列号相同的序列号进行判断。如果本地记录着与接收到的报文的序列号相同的序列号，那么执行S506；如果本地没有记录与接收到的报文的序列号相同的序列号，那么执行S507，随后再执行S508。
S506’，丢弃该业务报文。
S507’，转发模块记录已收到的PLC业务报文的序列号。
可选地，S505’中转发模块还可以在定时器窗口内判断是否已收到PLC业务报文。 示例性地，这里的定时器窗口的时长可以根据业务场景在初始化时配置。定时器到期后，需要先清除PLC业务报文的序列号，再重启定时器。
示例性地，这里的定时器窗口的时长可以根据业务场景在初始化时配置。定时器到期后，需要先清除PLC业务报文接收标记(例如将上述状态位归为0)，再重启定时器。
本申请实施例，通过CPE1和CPE2分别从PLC远控台接收PLC业务报文，使得CPE1和CPE2可以为PLC提供无线双收功能，随后CPE2将接收到的PLC业务报文发送给CPE1，由CPE1对接收到的PLC业务报文进行去重处理后发送给PLC，可以实现PLC对报文的选收，提高报文传输的高可靠性。其中，通过在CPE1和CPE2之间设置互联端口，实现PLC对业务报文的选收，相对于使用工业交换机提供类似的功能，可以降低PLC与PLC远控台的端到端传输对设备部署的依赖和网络部署成本，以便于系统的灵活、快速部署。
