AN设备可以为采用不同的无线接入技术。目前的无线接入技术有两种类型:3GPP接入技术(例如,第三代(3rd generation,3G)、第四代(4th generation,4G)或5G系统中采用的无线接入技术)和非3GPP(non-3GPP)接入技术。3GPP接入技术是指符合3GPP标准规范的接入技术,例如,5G系统中的接入网设备称为下一代基站节点(next generation Node Base station,gNB)或者RAN设备。非3GPP接入技术可以包括以无线保真(wireless fidelity,WiFi)中的接入点(access point,AP)为代表的空口技术、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)、码分多址(code division multiple access,CDMA)等。AN设备可以允许终端设备和3GPP核心网之间采用非3GPP技术互连互通。
AN设备能够负责空口侧的无线资源管理、服务质量(quality of service,QoS)管理、数据压缩和加密等功能。AN设备为终端设备提供接入服务,进而完成控制信号和用户数据在终端设备和核心网之间的转发。
AN设备例如可以包括但不限于:宏基站、微基站(也称为小站)、无线网络控制器(radio network controller,RNC)、节点B(Node B,NB)、基站控制器(base station controller,BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如,home evolved NodeB,或home Node B,HNB)、基带单元(baseband unit,BBU),WiFi系统中的AP、WiMAX中的(base station,BS)、无线中继节点、无线回传节点、传输点(transmission point,TP)或者发送接收点(transmission and reception point,TRP)等,还可以为5G(如,NR)系统中的gNB或传输点(TRP或TP),5G系统中的基站的一个或一组(包括多个天线面板)天线面板,或者,还可以为构成gNB或传输点的网络节点,如分布式单元(distributed unit,DU),或者下一代通信6G系统中的基站等。
本申请实施例对AN设备所采用的具体技术和具体设备形态不做限定。
3、UPF
作为和数据网络的接口,UPF主要负责完成用户面数据转发、基于会话/流级的计费统计,带宽限制等功能。例如,UPF可以从DN接收用户面数据,并通过AN设备将用户面数据发送给终端设备。UPF还可以通过AN设备从终端设备接收用户面数据,并转发到DN。
4、DN
DN主要用于为UE提供数据服务的运营商网络。例如,因特网(Internet)、第三方的业务网络、互联网协议多媒体服务业务(Internet protocol multi-media service,IMS)网络等。应用服务器(application server,AS)可以属于DN网络的一部分。

8、AF
AF主要传递应用侧对网络侧的需求,例如,QoS需求或用户状态事件订阅等。AF可以是第三方功能实体,也可以是运营商部署的应用服务,如IMS语音呼叫业务。对于第三方应用的应用功能实体,其与核心网进行交互时还可经由NEF进行授权处理,例如第三方应用功能直接向NEF发送请求消息,NEF判断该AF是否被允许发送该请求消息,若验证通过,则将转发该请求消息至对应PCF或UDM。
9、NEF
NEF主要用于安全地向外部开放由3GPP网络功能提供的业务和能力等。
10、UDM
UDM主要负责管理签约数据、用户接入授权等功能。
11、UDR

在图1所示的网络架构中,各网元之间可以接口通信。各网元之间的接口可以是点对点接口,也可以是服务化接口,本申请不予限制。
应理解,上述所示的网络架构仅是示例性说明,适用本申请实施例的网络架构并不局限于此,任何能够实现上述各个网元的功能的网络架构都适用于本申请实施例。
还应理解,图1中所示的AMF、SMF、UPF、PCF、UDM、UDR、NEF、AF等功能或者网元,可以理解为用于实现不同功能的网元,例如可以按需组合成网络切片。这些网元可以各自独立的设备,也可以集成于同一设备中实现不同的功能,或者可以是硬件设备中的网络元件,也可以是在专用硬件上运行的软件功能,或者是平台(例如,云平台)上实例化的虚拟化功能,本申请对于上述网元的具体形态不作限定。
还应理解,上述命名仅为便于区分不同的功能而定义,不应对本申请构成任何限定。本申请并不排除在6G网络以及未来其它的网络中采用其他命名的可能。例如,在6G网络中,上述各个网元中的部分或全部可以沿用5G中的术语,也可能采用其他名称等。
随着通信技术的发展,以5G通信系统为代表的无线通信系统逐渐成为工业通信系统的连接介质,工业现场的工业设备可以接入无线通信系统,并通过无线通信系统与其他工业设备进行通信。一种可能的方式,工业现场的工业设备例如可编程逻辑控制器(programmable logic controller,PLC)以及输入输出(input output,IO)设备等可以通过CPE实现无线接入。这样为工业设备提供了更加灵活的组网方式,可以更好地支持需要移动性和灵活组网兼顾的新型工业设备,例如,自动引导车(automated guided vehicle,AGV)等。
图2是工业设备接入无线通信系统的一种示意图。图2中涉及的无线通信系统可以是如图1所示的通信系统,但不限定。
如图2所示,工业设备可以通过CPE接入无线通信网络。例如,PLC#1可以通过CPE#1与RAN建立连接,IO设备#1可以通过CPE#2与RAN建立连接,IO设备#2和IO设备#3可以通过CPE#3与RAN建立连接。需要说明的是,一个CPE可以对应一个或多个工业设备,例如,CPE#1对应于PLC#1,CPE#3对应于IO设备#2和IO设备#3。还需要说明的是,工业设备可以通过有线方式或无线方式与CPE连接,本申请不予限制。还需要说明的是,当工业设备本身可以具备无线接入能力时,工业设备也可以直接接入无线通信网络,而不需要通过CPE。工业设备也可以通过交换机(switch,SW)与UPF建立连接。例如,PLC#2可以通过SW与UPF建立连接。工业设备可以通过有线方式与SW连接。
工业设备之间可以通过无线通信系统进行通信。一种可能的实现方式,发送端的工业设备通过CPE与无线通信系统建立连接,然后通过CPE、RAN将数据或信号发送至UPF,UPF将接收到的数据或信号发送至接收端的工业设备接入的RAN,进而发送至接收端的工业设备。以PLC#1与IO设备#1之间的通信为例,PLC#1将数据或信号发送至CPE#1,CPE#1将数据或信号发送至CPE#1接入的RAN,该RAN将数据发送至UPF;UPF将接收到的数据发送至IO设备#1通过CPE#2接入的RAN,该RAN将接收到的数据或信号通过CPE#2发送至IO设备#1。更详细的描述可以参见3GPP 23.501 4.4.6的相关内容,在此不再详述。
相比于采用有线连接介质,无线通信系统的网络状态是不断在变化的。无线通信系统 不断变化的网络状态会对业务产生影响。
针对上述情况,本申请提供了一种通信方法和通信装置,能够实现工业通信系统中的装置向无线通信系统输出信息,使得无线通信系统可以根据该信息对工业通信系统的装置进行更合理的调度,从而降低无线通信系统的网络状态会对业务产生影响。
为便于理解本申请实施例,在介绍本申请实施例之前,先做出以下几点说明。
第一,在本申请中,对于通信装置是归属于无线通信系统,还是归属于工业通信系统,不做严格的划分。工业通信系统以无线通信系统为连接介质,无线通信系统可以看做工业通信系统的一部分,换个角度,工业通信系统可以看做无线通信系统的一部分,本申请不予限制。例如,下文涉及的第二装置既可以作为工业通信网络中的IO设备,又可以作为无线通信息中的网元,从而可以以第二装置为接口,实现工业通信系统与无线通信系统之间的通信。
第二,在本申请中,工业通信系统也可以称为工业通信网络、工业现场网络、工业以太网、工业通信网络系统等,为了描述方便,下文统一称为工业通信系统。无线通信系统也可以称为无线通信系统网络、无线通信网络、3GPP网络、无线网络等,为了描述方便,下文统一称为无线通信系统。
其中,本申请对于工业通信网络采用的通信协议不作具体限定。例如,工业通信网络采用高速以太网(high speed ethernet,HSE)、Modbus、Profinet、Profibus、Ethernet/IP、和EtherCAT等。
第三,在本申请中,“用于指示”或“指示”可以包括用于直接指示和用于间接指示,或者说“用于指示”或“指示”可以显式地和/或隐式地指示。例如,当描述某一信息用于指示信息I时,可以包括该信息直接指示I或间接指示I,而并不代表该信息中一定携带有I。又例如,隐式指示可以基于用于传输的位置和/或资源;显式指示可以基于一个或多个参数,和/或一个或多个索引,和/或一个或多个它所表示的位模式。
第四,本申请对很多特性所列出的定义仅用于以举例方式来解释该特性的功能,其详细内容可以参考现有技术。

第六,“预先定义”可以通过在设备(例如,包括网络设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现,本申请对于其具体的实现方式不做限定。其中,“保存”可以是指,保存在一个或者多个存储器中。所述一个或者多个存储器可以是单独的设置,也可以是集成在编码器或者译码器,处理器、或通信装置中。所述一个或者多个存储器也可以是一部分单独设置,一部分集成在译码器、处理器、或通信装置中。存储器的类型可以是任意形式的存储介质,本申请并不对此限定。

下文将结合附图详细说明本申请提供的通信方法。本申请提供的实施例可以应用于上述图2所示的网络架构中,但不作限定。
图3是本申请提供的通信方法的示意性流程图。
图3所示的方法300应用于工业通信系统,该工业通信系统中的第一装置可以通过无线通信系统与工业通信系统中的其他装置进行通信。方法300可以由工业通信系统中的第一装置和第二装置执行,也可以由应用于第一装置和第二装置的模块或单元执行,下文统一描述为第一装置和第二装置。
图3所示的方法300可以包括以下内容的至少部分内容。
步骤301,第一装置确定第一信息。
其中,第一信息用于第一装置的无线通信调度。
一种可能的实现方式,第一信息包括工业通信系统的组态信息、第一请求信息和/或第一装置的业务状态信息。
其中,工业通信系统的组态信息可以包括以下信息中的至少一个:工业通信系统中每个IO设备对应流的PNIO(profinet IO)消息的长度、每个IO设备对应的通信周期、看门狗时间/因子、以及PLC与每个IO设备间的通信关系等。第一请求信息用于请求无线通信系统调整第一装置的调度信息。第一装置的业务状态信息可以包括端到端(end-to-end,E2E)的丢包状态信息、IO状态信息等。其中,IO状态信息可以指示IO状态为正常或故障,E2E丢包状态信息和IO状态信息是针对一路IO的E2E丢包状态信息和IO状态信息。
这里的第一装置可以为工业通信系统中的PLC或IO设备。
步骤302,第一装置向无线通信网络中的网络开放功能网元发送第一信息。
相应地,网络开放功能网元接收来自第一装置的第一信息。
一种可能的实现方式,第一装置向网络开放功能网元发送第一信息的方式可以如图3所示,即第一装置通过第二装置向无线通信网络中的NEF发送第一信息,其中,第二装置支持与无线通信网络中的网络开放功能网元通信。
这里的第二装置既可以作为工业通信系统中的IO设备,又可以作为无线通信系统的设备。网络开放功能网元可以是图1所示的NEF,也可以是其他具备与NEF功能相同或类似功能的网元,例如业务能力开放功能(service capability exposure function,SCEF)等。
作为一个示例,第二装置为在第一AF上建立的功能实例,该功能实例具备IO设备的功能,使得该功能实例具备与工业通信系统中的工业设备(例如IO设备或PLC等)通信的能力;该功能实例建立在第一AF上,因此该功能实例可以通过第一AF与无线通信系统中的网元通信,例如,第一AF可以通过网络开放功能网元与无线通信系统中的其他网元进行通信,这样该功能实例又具备与无线通信系统中的网元通信的能力。第二装置的设计和组态的具体实现方式将结合下文的图8以举例的方式进行描述。
“第二装置支持与无线通信网络中的网络开放功能网元通信”可以是第二装置具备直接与无线通信网络中的网络开放功能网元通信的能力,也可以是第二装置间接地与无线通 信网络中的网络开放功能网元通信。例如,若第二装置为建立在第一AF上的功能实例,则第二装置可以通过第一AF向网络开放功能网元发送第一信息。
另一种可能的实现方式,若第一装置具备与无线通信网络中的网络开放功能网元直接通信的能力,则第一装置也可以不通过第二装置向无线通信网络中的NEF发送第一信息。
这样,在方法300中,无线通信系统中的网络开放功能网元可以从第一装置获取用于第一装置的无线通信调度的信息。换句话说,工业通信系统中的装置可以向无线通信系统输出信息,使得无线通信系统可以根据该信息对工业通信系统的装置进行调度。这样有助于无线通信系统对工业通信系统的装置进行更合理的调度,从而降低无线通信系统的网络状态会对业务产生影响。
基于以上内容,工业通信系统的第一装置可以向无线通信系统输出用于第一装置的无线通信调度的信息。在另一些实施例中,无线通信系统也可以向工业通信息系统输出用于控制业务的信息。下面对无线通信系统向工业通信息系统输出用于控制业务的信息的方式进行描述。
图4是本申请提供的另一通信方法的示意性流程图。
图4所示的方法400应用于工业通信系统,该工业通信系统中的第一装置可以通过无线通信系统与工业通信系统中的其他装置进行通信。方法400可以由工业通信系统中的第一装置和第二装置执行,也可以由应用于第一装置和第二装置的模块或单元执行,下文统一描述为第一装置和第二装置。
图4所示的方法400可以包括以下内容的至少部分内容。
步骤401,第一装置从无线通信系统的网络开放功能网元获取第二信息。
其中,第二信息包括无线通信系统的网络状态信息。第二信息可以用于控制第一业务。这里的第一业务可以为工业通信系统或第一装置执行的业务。
一种可能的实现方式,网络状态信息包括以下信息的至少一个:第一装置的无线网络状态信息、无线通信系统的空口容量信息、以及无线通信系统的网络连接关系。
其中,第一装置的无线网络状态信息可以包括以下信息中的至少一个:通信服务可用性(communication service availability)、通信服务可靠性(communication service reliability)、端到端时延(end-to-end latency)、服务比特率(service bit rate)、和误包率(packet error ratio)等。无线通信系统的空口容量信息可以包括以下信息中的至少一个:无线通信系统的剩余空口容量、无线通信系统的已使用的空口容量、无线通信系统的空口拥塞状态、和无线通信系统的空口信道质量等。无线通信系统的网络连接关系可以包括第一装置在无线通信系统的连接关系,换句话说,第一装置与无线通信系统中为第一装置提供服务的网络设备的连接关系,例如第一装置接入的RAN、以及采用的UPF等。
这里的第一装置可以为工业通信系统中的PLC或IO设备,也可以是第一AF,第一AF为工业生产相关的网元。网络开放功能网元可以是图1所示的NEF,也可以是其他具备与NEF功能相同或类似功能的网元,例如SCEF等。
一种可能的实现方式,第一装置从网络开放功能网元获取第二信息的方式可以如图4所示,即第一装置可以通过第二装置从网络开放功能网元获取第二信息。第二装置的描述可以参考图3中的相关描述,在此不再赘述。
另一种可能的实现方式,若第一装置具备与无线通信网络中的NEF直接通信的能力, 则第一装置也可以不通过第二装置,直接从网络开放功能网元获取第二信息。例如,第一装置为第一AF,则第一装置可以直接从网络开放功能网元获取第二信息。又例如,第一装置为具备与网络开放功能网元直接通信的能力的PLC,则第一装置可以直接从网络开放功能网元获取第二信息。
步骤402,第一装置根据第二信息,控制第一业务。
一种可能的实现方式,在工业通信系统发生故障和/或无线通信系统发生故障时,第一装置根据第二信息,对第一业务执行业务降级。相比于接收到故障信号直接停机,可以降低故障对于第一业务的影响。
例如,第一装置接收到工业通信系统的故障信号,并且根据第二信息确定无线通信系统的网络状态波动较大,在此情况下,第一装置接收到的报警信号可能是由于无线通信系统的网络状态较差导致的,因此第一装置可以先对第一业务执行业务降级,待无线通信系统的网络状态恢复,再正常执行第一业务。
另一种可能的实现方式,在工业通信系统发生故障和/或无线通信网络发生故障时,第一装置根据第二信息,确定等待预设时长;若在预设时长内,在第一装置和/或无线通信系统的故障未消除,则第一装置终止第一业务。相比于接收到故障信号直接停机,可以降低故障对于第一业务的影响。

图9和图10是工业通信系统运行态的一个示意图。
如图9所示,虚拟Profinet IO设备在加入(例如通过图8所示的方式)到工业通信系统后,虚拟Profinet IO设备可以作为PLC与3GPP网络的通信的中介,换句话说,3GPP网络在工业通信系统中可以看作是一个IO设备。工业通信系统(例如工业通信系统中的PLC)可以通过与虚拟Profinet IO设备通信,实现获取3GPP网络的网络状态信息和/或实现对3GPP网络的控制。具体地,虚拟Profinet IO设备通过IFES、NEF获取3GPP网络的网络状态信息,以及通过IFES、NEF将向3GPP网络提供工业通信网络的信息。工业通信系统(例如工业通信系统中的PLC)可以向虚拟Profinet IO设备提供用于调度工业通信系统中的PLC或IO设备的无线调度的信息,以便虚拟Profinet IO设备将相应地信息发送至3GPP网络或者对3GPP网络进行控制。
工业通信系统的具体工作流程可以如图10所示。
1)工业通信系统获取3GPP网络的网络状态信息的流程
步骤1001,IFES通过与NEF之间的接口从NEF获取3GPP网络的网络状态信息。
步骤1002,IFES通过内部接口将3GPP网络的网络状态信息同步至虚拟Profinet IO设备。
步骤1003,PLC通过UPF获取虚拟Profinet IO设备上保存的3GPP网络的网络状态信息。
需要说明的是,步骤1003为可选步骤。例如,当由虚拟Profinet IO设备执行对3GPP网络的控制时,PLC可以不用获取3GPP网络的网络状态信息。
2)工业通信系统控制3GPP网络的流程
步骤1004,IFES通过RAN和UPF从工业设备获取Profinet IO报文。
例如,当工业设备为IO设备时,IFES通过RAN1和UPF从IO设备获取Profinet IO报文,Profinet IO报文可以包括E2E丢包状态信息、IO状态信息等。
又例如,当工业设备为PLC时,IFES通过RAN2和UPF从PLC获取Profinet IO报文,Profinet IO报文可以包括以下信息中的至少一个:针对3GPP网络的控制信息、针对每个IO设备的控制信息、每个IO设备的通信状态信息、以及组态信息。
步骤1005,IFES通过内部接口将获取到的Profinet IO报文同步至虚拟Profinet IO设备。
步骤1006,虚拟Profinet IO设备通过IFES调用NEF的接口,实现对3GPP网络和/或IO设备的控制。
其中,对3GPP网络的控制可以包括配置IO设备的优先级、请求3GPP网络为特定业务预留资源、或请求3GPP网络释放为某个业务资源等,本申请不予限制。
需要说明的是,PLC除了可以通过UPF、IFES、虚拟Profinet IO设备和RAN1向IO设备发送Profinet IO报文,也可以通过RAN2、UPF、RAN1向IO设备发送Profinet IO报文。
需要说明的是,上述流程1)和2)可以单独实施,也可以以恰当的方式结合在一起实施,本申请不予限制。上述流程1)和/或2)可以按照一定周期不断执行,也可以在一些特殊情况下执行,例如,在IO设备发生故障、更新生产任务或初始化生产任务时执行。
图9和图10中涉及的各信息的详细描述可以参考图8中的描述,在此不再赘述。
图11是工业通信系统故障态的一个示意图。
在本申请中,当IO设备发生故障时,相比于直接向IO设备发送停机指令等待工作人员检修,本申请的PLC可以结合3GPP网络的网络状态信息,判断是否满足停机条件,若不满足停机条件,PLC可以控制IO设备实现业务降级或继续等待若干循环周期。
在执行图8的步骤6时,可以编写中断程序,以便对工业现场网络的IO故障进行处理。例如,可以定义中断OB,该中断OB用于检测工业通信系统中是否出现IO故障。
作为一个示例,IO设备发生故障。当工业通信系统中出现IO故障时,PLC可以结合3GPP网络的网络状态信息,对该IO故障进行处理。一种可能的实现方式,PLC根据3GPP网络的网络状态信息,判断是否满足停机条件,若不满足停机条件,PLC可以控制IO设备实现业务降级或继续等待若干循环周期。例如,如图11所示,在循环周期T1,IFES获知IO设备发生故障;IFES通过虚拟Profinet IO设备向PLC发送报警信息,触发PLC的OB86中断,以便向PLC通知IO设备发生故障;PLC在获知IO设备发生故障后,根 据3GPP网络的网络状态信息,确定针对该IO设备继续等待几个循环周期(例如,2个);若在该循环周期内,仍未接收来自该IO设备的报文,PLC下发停机指令。
作为另外一个示例,3GPP网络的网络质量下降,或者可以理解为,3GPP网络发生故障。当3GPP网络的网络质量下降时,PLC可以结合当前3GPP网络的网络状态信息,判断是否满足停机条件,若不满足停机条件,PLC可以控制IO设备实现业务降级,例如,PLC可以向IO设备发送控制指令以便控制IO设备实现业务降级。
