Description

一种传输信息的方法和装置
本申请要求于2018年1月22日提交中国专利局、申请号为201810060201.9、申请名称为“一种传输信息的方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，更具体地，涉及通信领域中一种传输信息的方法和装置。
背景技术
现有的5G定义了基于服务质量(quality of service,QoS)流(flow)的框架。即，在一个会话中，可以基于QoS流为报文提供不同的传输需求。也就是说，属于同一个QoS流的报文可以获得相同的传输服务。
现有的5G移动网络通过区分服务(differentiated services，DiffServ)来实现QoS流的传输需求。例如，在上行传输时，基站可以在报文中添加区分服务代码点(differentiated services code point，DSCP)字段，其中，DSCP字段中的DSCP值是基于QoS流的参数确定的。这样，可以通过DSCP值区分不同的QoS服务。网络中的交换机可以根据报文中的DSCP字段为报文分配不同的优先级的传输队列，从而为不同的报文提供不同的传输服务。
该现有技术的报文转发机制是一种尽力而为的转发机制，即，交换机对报文中优先级较高的报文进行优先转发。当大量的报文在一瞬间达到端口并且相同优先级的报文较多时，基于交换机的端口的缓存能力以及队列的长度等原因，并不能保证所有相同优先级的报文都能在有效的时延范围内被转发，即，无法对不同的报文提供确定性的传输性能。尤其是对于低时延高可靠通信(ultra-reliable and low latency communications，URLLC)的业务而言，现有技术更是不能满足其传输性能。
因而，亟需提供一种技术，有助于满足针对移动网络中报文的传输性能的需求。

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。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(global system of mobile communication，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、通用分组无线业务(general packet radio service，GPRS)系统、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)系统、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、未来的第五代(5th generation，5G)系统或新无线(new radio，NR)通信系统等。
随着下一代通信系统研究的全面开展并逐渐深入，5G将支持各种类型的网络部署和应用类型。其中包括：更高速率体验和更大带宽的接入能力，例如增强型移动宽带(enhanced mobile broadband,eMBB)；更大规模、更低成本的机器类设备的接入和管理，例如大规模机器类通信(massive machine type communication,mMTC)；更低时延和高可靠的信息交互，例如超高可靠与低延迟通信(ultra reliable and low latency communication,URLLC)等。为了满足上述需求，5G定义了基于服务质量(quality of service,QoS)流(flow)的框架。其可以支持保障流速率的QoS流或不保障流速率的QoS流。
现有的5G网络通过区分服务(differentiated services，DiffServ)来实现QoS流的传输需求。例如，在上行传输时，基站可以在报文中添加区分服务代码点(differentiated services code point，DSCP)字段，其中，DSCP字段中的DSCP值是基于QoS流的参数确定的，网络中的交换机可以根据报文中的DSCP字段为报文分配不同优先级的传输队列，从而为不同的报文提供不同的传输服务。
但是，该现有技术的报文转发机制是一种尽力而为的转发机制。当大量的报文在一瞬间达到端口后，交换机只能对报文中优先级较高的报文进行优先转发。但是，当相同优先级的报文较多时，基于交换机的端口的缓存能力以及队列的长度等原因，并不能保证所有相同优先级的报文都能在有效的时延范围内被转发。因此，现有技术中的传输网络是一种尽力而为的网络。对于任何优先级传输性能的报文，该现有技术都无法对不同的报文提供确定性的传输性能。尤其是对于URLLC业务而言，现有的尽力而为的传输网络更是不能满足其传输性能，大大影响了数据传输效率。
因而，本申请实施例提供了一种传输信息的方法，有助于满足针对移动网络中报文的传输性能的需求。
下面，结合图1至图6对本申请实施例进行详细说明。
首先，对本申请实施例的网络架构进行简单说明。图1所示为本申请实施例的一种可能的网络架构100的示意图。如图1所示，该网络架构100包括控制设备110、终端设备 120、接入网设备130、用户面功能(user plane function，UPF)网元140和应用服务器150。下面，对每个设备进行简单描述：
控制设备110：主要用于向与该控制设备通信连接的设备(例如，该终端设备120、接入网设备130、用户面功能网元140和应用服务器150中的任一个)发送用于发送报文的各种信息。例如，下文中的第一标识信息、第一指示信息等。
可选地，该控制设备110可以为会话管理功能(session management function，SMF)网元。SMF网元主要用于会话管理、针对终端设备的IP地址分配和管理、UPF网元的选择和控制。SMF网元还可用于控制UPF网元转发流量的目的地、控制方面的策略执行以及QoS管理。
终端设备120：可以包括用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
接入网设备130：用于为特定区域的授权用户提供入网功能，并能够根据用户业务的需求等使用不同质量的传输隧道。接入网设备130能够管理无线资源，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，接入网设备也可以理解为传统网络中的基站。
本申请实施例中的接入网设备可以是GSM系统或CDMA中的基站(base transceiver station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(evolutional nodeB，eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，还可以是gNB(gNodeB)，或者该接入网设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。
UPF网元140：用于分组数据的路由和转发，以及用户面数据的QoS处理等。
应用服务器150：表示终端设备需要通过移动网络访问的服务端设备，用于为终端设备提供业务服务，可以理解为业务逻辑的实现部分。
应理解，上述网络架构100中包括的各个设备仅为示意性说明，该网络架构100中还包括其他设备，只是图1中未示出而已。例如，该网络架构100包括数据网元，例如，该数据网元可以是统一数据管理(unified data management，UDM)网元，主要用于鉴权凭据处理、用户标识处理、接入授权和订阅管理等。此外，在本申请实施例中，数据网元还可以用于维护网络中关于传输通道的信息。再例如，该网络架构100还包括接入和移动管理功能(access and mobility management function，AMF)网元，主要用于移动性管理和接入管理等。AMF网元可以用于实现移动性管理实体(mobility management entity，MME)功能中除会话管理之外的其它功能，例如合法监听以及接入授权\鉴权等功能。
在图1中，接入网设备130与UPF140之间的网络为传输网络#A，UPF140与应用服 务器150之间的网络为传输网络#B。其中，该终端设备120与该接入网设备130之间通过空口传输报文。每个传输网络至少包括报文的发送端、报文的接收端以及用于报文转发的交换机或路由器(图中仅示出传输网络中的发送端和接收端，未示出传输网络中的交换机或路由器)。对于传输网络#A而言，在上行传输时，发送端为接入网设备130，接收端为UPF网元140，在下行传输时，发送端为UPF网元140，接收端为接入网设备130。对于传输网络#B而言，在上行传输时，发送端为UPF网元140，接收端为应用服务器150，在下行传输时，发送端为应用服务器150，接收端为UPF网元140。
在每个传输网络中，系统中都预配置有至少一条用于传输报文的传输通道，这里，传输通道可以理解为用于传输报文的传输资源，任意两条传输通道的传输资源不同。在本申请实施例中，一个传输通道包括多种参数。需要说明的是，图1中还可以包括多个UPF网元(例如，下文方法500中的目标UPF网元和锚点UPF网元)，相邻的两个UPF网元之间的传输网络也可以预配置有至少一条传输通道。
下面，以一条传输通道为例，对传输通道的各种参数进行说明。
传输通道第一类标识：该传输通道第一类标识用于标识该传输通道。其中，该传输通道第一类标识是针对于一个传输网络的标识，即，在不同的传输网络中，不同传输通道的传输通道第一类标识可能相同，但是，在同一个传输网络中，不同传输通道的传输通道第一类标识不同。
传输通道第二类标识：该传输通道第二类标识用于唯一标识该传输通道。其中，该传输通道第二类标识针对包括至少一个传输网络的整个移动网络中的标识，即，在整个移动网络范围内，不同传输通道的传输通道第二类标识都不同。
发送端标识：用于在整个移动网络范围内唯一标识报文的发送端，例如，针对于传输网络#A中报文的上行传输，发送端标识用于标识接入网设备130。
接收端标识：用于在整个移动网络范围内唯一标识报文的接收端，例如，针对于传输网络#A中报文的上行传输，接收端标识用于标识UPF网元140。
传输通道的传输性能：表示传输通道能够为报文传输过程中提供的确定性传输服务的性能，其中，该确定性传输服务的性能包括：报文传输的最大时延、报文传输的最大的时延抖动，报文传输服务的可靠性中的至少一项。
在本申请实施例中，在同一个传输网络中，一条传输通道可以对应至少一个报文流，即，一个传输通道用于传输属于该至少一个报文流的报文。其中，每个报文流至少包括如下参数：
报文流的传输性能：报文流所需要的确定性服务传输的性能，其中，该确定性传输服务的性能包括：报文传输的最大时延、报文传输的最大的时延抖动、报文传输服务的可靠性中的至少一项。
报文流的报文发送频率：报文流所需要的最大的报文发送频率。
上述报文流的相关参数可以预配置在系统，例如，可以预配置于任一个具有数据维护功能的网元，例如，UDM网元。
在本申请实施例中，报文流可以理解为满足预设条件的一组报文的总称。该预设条件可以有多种。例如，该预设条件可以是报文流中的报文的目标IP地址相同，或者，该预设条件可以是报文流中的报文的端口号相同，或者，该预设条件可以是报文流中报文的 QoS相同。
当然，该预设条件也可以是上述多个预设条件的任意组合，本申请实施例不做任何限定。例如，若多个报文的源IP、目的IP、协议、端口号相同，可以将上述4个参数相同的报文归为一个报文流。
应理解，上述列举的报文流的预设条件仅为示意性说明，任何能够区分报文流的预设条件都在本申请实施例的保护范围内。
图2所示为根据本申请实施例的传输信息的方法的示意性交互图。
在本申请实施例中，为了便于区分与理解，将该接入网设备与该UPF网元之间的传输网络记为传输网络#A，将该UPF网元与该应用服务器之间的传输网络记为传输网络#B，将该第一网络设备记为网络设备#A，将第二网络设备记为网络设备#B。
该网络设备#A为一个传输网络中的发送端，该网络设备#B是一个传输网络中的接收端，并且，在一个传输网络中还包括用于转发报文的交换机。其中，该网络设备#A可以是接入网设备、UPF网元或应用服务器中的任一个。
例如，在传输网络#A中，在上行传输中，该网络设备#A为该接入网设备，该网络设备#B为UPF网元，在下行传输中，该网络设备#A为UPF网元，该网络设备#B为接入网设备。在传输网络#B中，在上行传输中，该网络设备#A为UPF网元，该网络设备#B为应用服务器，在下行传输中，该网络设备#A为应用服务器，网络设备#B为UPF网元。
在步骤S211中，控制设备从配置于网络设备#A与网络设备#B之间的至少一条传输通道中确定第一传输通道(为了便于区分与理解，记为传输通道#1)，该传输通道#1用于传输属于至少一个报文流的报文。该传输通道#1当前所支持的报文发送频率大于或等于该至少一个报文流的报文发送频率的总和，该传输通道#1的传输性能满足该至少一个报文流的传输性能。
可选地，该控制设备为SMF网元。
例如，在该网络设备#A与该网络设备B之间的传输网络中预配置有该至少一条传输通道，该控制设备可以基于终端设备的会话获取与该会话对应的报文流，从而为与该会话对应的报文流确定满足条件的传输通道，其中，基于该会话的报文流确定的传输通道可以是一条传输通道，也可以是多条传输通道，只要满足条件即可，本申请实施例并不限于此。
下面，以基于该会话的报文流确定的传输通道中的传输通道#1为例进行说明。该传输通道#1与该至少一个报文流对应，即，该传输通道#1用于传输属于该至少一个报文流的报文，或者说，该传输通道#1传输的报文所属的报文流属于该至少一个报文流，其中，该至少一个报文流属于对应于该会话的报文流。
其中，该控制设备至少基于两种参数确定该传输通道#1，即报文发送频率和传输性能。
可选地，该控制设备从配置于第一网络设备和第二网络设备之间的至少一条传输通道中确定第一传输通道，包括：
该控制设备根据该至少一个报文流中每个报文流的传输性能和该至少一条传输通道中传输通道的传输性能，并且，根据该至少一条报文流中每个报文流的报文发送频率和该至少一条传输通道中传输通道当前所支持的报文发送频率，从该至少一条传输通道中确定该第一传输通道。
例如，该控制设备获得该至少一个报文流的参数。其中，一个报文流的参数至少包括 一个报文流的传输性能和报文发送频率，并且，该控制设备获取该至少一条传输通道中传输通道的至少两个参数，即传输通道的传输性能和传输通道当前所支持的报文发送频率，这样，该控制设备分别基于报文流的报文发送频率和传输通道当前所支持的报文发送频率，以及，报文流的传输性能和传输通道的传输性能，从该至少一条传输通道中确定该传输通道#1。
其中，该控制设备分别基于报文流的报文发送频率和传输通道当前所支持的报文发送频率，以及，报文流的传输性能和传输通道的传输性能，从该至少一条传输通道中确定与该至少一个报文流对应的传输通道(即，该传输通道#1)，应该至少满足两个条件：
条件#1：传输通道当前所支持的报文发送频率大于或等于该至少一个报文流的报文发送频率的总和；
条件#2：传输通道的传输性能满足该至少一个报文流的传输性能。
举例来说，在条件#1中，若该至少一个报文流的报文发送频率的和小于或等于100次/秒，那么，基于该至少一个报文流确定的传输通道当前所支持的报文发送频率大于或等于100次/秒。在条件#2中，传输通道的性能需要满足该至少一个报文流中每个报文流的传输性能，例如，若该至少一个报文流中最小的时延为2s，那么，基于该至少一个报文流确定的传输通道的时延小于或等于2s。
这样，该控制设备基于上述条件#1和条件#2，从该至少一个传输通道中确定满足条件的该传输通道#1。
应理解，本申请实施例中所说的传输通道当前所支持的报文发送频率指的是该传输通道剩余的报文发送频率。
在本申请实施例中，该控制设备获取该至少一个报文流的参数的方式有多种方式，本申请实施例不做任何限定：
例如，在会话建立过程中，该控制设备可以接收来自应用服务器发送的至少一个报文流的参数。
再例如，该控制设备可以配置有系统能够支持的报文流的参数，在会话建立过程中，该控制设备获取用于指示会话的至少一个报文流的信息，从而可以基于该信息从配置的报文流的参数中确定该至少一个报文流的参数。
再例如，其他网元(例如，UDM网元)可以配置有系统能够支持的报文流的参数，在会话建立过程中，该控制设备获取会话的至少一个报文流，从而可以基于会话的至少一个报文流，与该其他网元通过相关信令交互获取该至少一个报文流的参数。
同理，该控制设备获取该至少一条传输通道中传输通道的参数的方式也可以有多种方式，本申请实施例不做任何限定：
例如，该控制设备可以配置有该至少一条传输通道的参数。
再例如，其他网元(例如，UDM网元)中可以配置有该至少一条传输通道的参数，该控制设备可以从其他网元处获取该至少一条传输通道的参数。
应理解，上述虽然以确定传输通道#1的过程为例进行说明，但不应对本申请实施例构成限定。在具体实现过程中，基于该会话的报文流中的其他报文流确定其他传输通道的过程与基于该至少一个报文流确定该传输通道#1的过程相同，为了简洁，此处不再赘述。
在步骤S212中，该控制设备向该网络设备#A发送用于标识该传输通道#1的标识信 息#1。
这样，该网络设备#A可以基于该标识信息#1，确定发送报文时可以使用的传输通道。当然，该传输通道#1能够传输的报文所属的报文流属于该至少一个报文流。
其中，如上文所述，传输通道有两种标识，即传输通道第一类标识和传输通道第二类标识，这里，该标识信息#1可以是用于指示传输通道第一类标识的标识信息，或者，也可以是用于指示传输通道第二类标识的标识信息。
需要说明的是，当基于该会话的报文流确定有多条传输通道时，每个标识信息用于标识一个传输通道，用于标识多条传输通道的多个标识信息都可以承载于一个消息中，该控制设备通过一个消息将该多条标识信息发送给该网络设备#A；或者，用于标识多条传输通道的多个标识信息分别承载于不同信息中，该控制设备通过发送不同信息将该多条标识信息发送给该网络设备#A。
下面，对该网络设备#A在该传输通道#1上发送报文的过程进行详细说明。
在步骤S213中，该网络设备#A获取第一报文(为了便于区分与理解，记为报文#1)，确定该报文#1所属的报文流属于哪些报文流，若该报文#1所属的报文流属于该至少一个报文流，则表示该网络设备#A可以使用该传输通道#1发送基于报文#1生成的第二报文(为了便于区分与理解，记为报文#2)，并且，在步骤S214中，该网络设备#A按照该传输通道#1的报文发送频率，使用该传输通道#1发送该报文#2。
这里，首先对该网络设备#A获取报文#1的方式进行说明：
在上行传输时，当该网络设备#A为接入网设备时，该网络设备#A接收终端设备发送的报文#1，当该网络设备#A为UPF网元时，该网络设备#A接收接入网设备发送的报文#1；
在下行传输时，当该网络设备#A为应用服务器时，该网络设备#A生成报文#1，当该网络设备#A为UPF网元时，该网络设备#A接收应用服务器发送的报文#1。
在本申请实施例中，该网络设备#A中配置有与该至少一个传输通道中传输通道对应的用于发送报文的转发信息，以传输通道#1为例，该传输通道#1的转发信息至少包括该传输通道#1的报文发送频率、在报文中添加的用于标识该传输通道#1的标签、为报文转发分配的队列和对应于队列的时间片。其中，时间片是分配给一个队列中用于传输报文的时间。此外，该用于标识该传输通道#1的标签可以与该标识信息#1的内容相同，也可以不同，只要能够标识该传输通道#1即可。
并且，用于在该网络设备#A与该网络设备#B之间转发报文的交换机也配置有该至少一个传输通道的转发信息。
例如，该网络设备#A确定该报文#1所属的报文流属于该至少一个报文流，也就确定了使用该传输通道#1发送基于该报文#1生成的该报文#2，那么，该网络设备#A基于该标识信息#1，从至少一个传输通道的转发信息中确定该传输通道#1的转发信息，并且，在该传输通道#1的转发信息中确定该传输通道#1的报文发送频率和用于标识该传输通道#1的标签。进而，网络设备#A将该用于标识该传输通道#1的标签添加至待发送报文，以生成该报文#2，按照该传输通道#1的报文发送频率发送该报文#2。用于在该网络设备#A与该网络设备#B之间转发报文的交换机在接收到该报文#2后，可以基于该传输通道#1的标签确定该传输通道#1的转发信息，并且，确定与该传输通道#1对应的队列以及用于队列 转发的时间片，进而，通过与该传输通道#1对应的队列以及用于队列转发的时间片向该网络设备#B转发该报文#2。
需要说明的是，该网络设备#A获取该报文#1后，需要进行协议栈的解封装和封装过程，生成报文#2。也就是说，该报文#1与该报文#2的原始数据相同，由于两个报文的发送端与接收端的不同，使得报文中添加的其他信息不同，该其他信息可以是通用分组无线服务隧道协议(general packet radio service tunneling protocol，GTP)报文头、用户数据报协议(user datagram protocol，UDP)报文头、IP报文头。
在移动网络中，由于移动性的存在，使得在不同时段内移动网络中传输的业务可能不同，从而导致在不同时段内移动网络中的带宽不同。因此，在系统为由第一网络设备和第二网络设备构成的传输网络中预配置至少一条传输通道的情况下，该控制设备需要基于当前会话生成的报文流，从该至少一条传输通道中确定能够传输属于报文流的报文的传输通道(例如，第一传输通道)，并且将用于标识传输通道的标识信息发送给该第一网络设备，使得该第一网络设备可以确定用于传输报文的传输通道。
在本申请实施例中，控制设备从该至少一个传输通道中确定的传输通道(例如，第一传输通道)的报文发送频率大于或等于该至少一个报文流的报文发送频率，以及，该第一传输通道的传输性能满足该至少一个报文流的传输性能。这样，该第一网络设备在确定报文所属的报文流属于该至少一个报文流时，基于该第一传输通道的报文发送频率使用该第一传输通道发送报文。由于在该第一网络设备和该第二网络设备之间的交换机中用于转发报文的时间片以及为报文转发分配的队列都是基于传输通道的频率配置的，在该第一网络设备使用对应于报文的第一传输通道发送报文时，用于转发报文的时间片是确定的，并且，为报文转发分配的队列的长度是有限制的，使得报文的传输时延可以控制在一定范围内，能够满足移动网络中不同报文的传输需求。
因此，本申请实施例的传输信息的方法，控制设备从配置于第一网络设备和第二网络设备之间的至少一个传输通道中确定用于传输属于至少一个报文流的报文的第一传输通道，且通过用于标识该第一传输通道的标识信息使得第一网络设备可以确定能够使用该第一传输通道传输属于该至少一个报文流的报文。其中，该第一传输通道的报文发送频率大于或等于该至少一个报文流的报文发送频率，且，该第一传输通道的传输性能满足该至少一个报文流的传输性能。进而，该第一网络设备在发送属于该至少一个报文流的报文时，按照该第一传输通道的报文发送频率使用该第一传输通道发送报文，能够有效地减少报文的传输时延，进而满足针对移动网络中报文的传输性能的需求。
在步骤213中，在该网络设备#A发送报文之前，需要确定待发送的第一报文所属的报文流是否属于该至少一个报文流，下面，对步骤213中的确定过程做详细说明。
可选地，该方法还包括：
该控制设备向该第一网络设备发送第一指示信息，该第一指示信息用于指示该至少一个报文流。
对应地，该第一网络设备接收该第一指示信息，且根据该第一指示信息和该第一报文中的字段，确定该第一报文所属的报文流属于该至少一个报文流，其中，该第一报文的字段用于指示该至少一个报文流。
其中，该报文#1的字段包括该报文#1中的至少一个字段，该至少一个字段是该报文 #1中的部分字段，当该报文#1的字段为多个字段时，该多个字段共同用于指示该至少一个报文流。
例如，该网络设备#A将接收到的该第一指示信息的内容与该报文#1中的字段进行匹配，若该第一指示信息能够与该报文#1中的字段匹配成功，则表示该报文#1所属的报文流属于该至少一个报文流，若该第一指示信息与该报文#1中的字段不能匹配成功，则表示该报文#1所属的报文不属于该至少一个报文流。
应理解，这里所说的匹配是否成功表示的是该第一指示信息与该报文#1中的至少一个字段匹配是否成功。
下面，对该指示信息的生成与该报文#1的关系进行说明。
发送端(例如，网络设备或终端设备)在发送报文前，会按照网络协议在报文中规定位置上添加对应的信息(例如，发送端设备按照网络协议在报文中规定的目的IP地址位置上添加应用服务器的IP地址)，从而正确传输报文，控制设备可以基于报文中规定位置添加的信息生成第一指示信息，即，将信息中指示不同内容的多个字段组合形成为第一指示信息。
例如，报文中规定位置上添加的信息中可以包括三个字段，第一字段用于指示报文的目的地址、第二字段用于指示端口号、第三字段用于标识报文所属的报文流的报文流标识，那么，该控制设备可以分别将上述三个字段作为该第一指示信息的内容，即，该第一指示信息包括该第一字段、第二字段或第三字段中的任一个；或者，该控制设备可以将该上述三个字段的两两组合的内容作为该第一指示信息的内容，例如，该第一指示信息包括该第一字段和该第二字段，该第一字段和该第二字段共同用于指示该至少一个报文流；再或者，该控制设备可以将上述三个字段作为该第一指示信息的内容，即，该第一指示信息包括该第一字段、第二字段和该第三字段，三个字段共同用于指示该至少一个报文流。此外，当多个字段共同用于指示该至少一个报文流，多个字段可以通过逻辑表达式来指示该至少一个报文流，例如，(not(字段1＝a))and(字段2＝b or字段3＝c)。
需要说明的是，当该控制设备基于会话的报文流确定包括该第一传输通道在内的多条传输通道时，该控制设备在向该网络设备#A发送用于标识该多个传输通道的多个标识信息时，也可以向该网络设备#A发送多个指示信息。该多个标识信息与该多个指示信息对应。每个标识信息所标识的传输通道对应的报文流即为对应的指示信息所指示的报文流。这样，该网络设备#A通过其中一个指示信息(例如，第一指示信息)确定待发送报文所属的报文流属于该第一指示信息所指示的报文流，可以使用对应该第一指示信息的标识信息所标识的传输通道发送报文。
作为示例而非限定，该网络设备#A不仅可以基于接收到的该第一指示信息和该报文#1的字段确定该报文#1所属的报文流属于该至少一个报文流，也可以采用其他方式确定该报文#1所属的报文流属于该至少一个报文流。例如，系统可以基于报文流的组合方式预配置多个指示信息，每个指示信息用于指示一个报文流组，其中，一个报文流组中包括至少一个报文流，且将该多个指示信息存储于该网络设备#A中，这样，该网络设备#A在发送报文之前，将报文与所有指示信息挨个进行匹配，若与其中一个指示信息(例如，第一指示信息)匹配成功，则表示报文所属的报文流属于该第一指示信息所指示的至少一个报文流，进而使用对应的传输通道发送报文。
在本申请实施例中，终端设备与网络设备之间不存在传输通道，终端设备与网络设备之间通过空口传输报文，且终端设备需要按照报文所属的报文流的报文发送频率发送报文，若该终端设备未按照报文所属的报文流的报文发送频率发送报文，可能会影响其他报文流对于传输性能的需求。
因此，本申请实施例还提供了一种可选的方式，继续如图2所示：
在步骤S221中，该控制设备向终端设备发送第一报文流频率信息(为了便于区分与理解，记为报文流频率信息#1)，该报文流频率信息#1用于指示该至少一个报文流中每个报文流的报文发送频率，进而，该终端设备接收该报文流频率信息#1。
在步骤S222中，该终端设备根据待发送的报文所属的报文流，从该报文流频率信息#1中确定该报文所属的报文流的报文发送频率，其中，该报文流属于该至少一个报文流。
在步骤S223中，该终端设备按照该报文所属的报文流的报文发送频率发送该报文。
例如，该控制设备可以通过上文所述方式获取该至少一个报文流的报文发送频率，向该终端设备发送用于指示该至少一个报文流中每个报文流的报文发送频率的报文流频率信息#1，可以使得终端设备使用报文所属的报文流的报文发送频率发送该报文。
应理解，当该网络设备#A为接入网设备时，该接入网设备获取的报文#1即为该终端设备发送的报文。
因此，本申请实施例提供的传输信息的方法，控制设备通过向终端设备发送用于指示至少一个报文流中每个报文流的报文发送频率的第一报文流频率信息，可以使得该终端设备可以使用报文所属的报文流对应的报文发送频率发送报文，有效地避免了由于该终端设备未按照报文流的报文发送频率发送报文而影响了其他报文流的报文的传输性能。
作为示例而非限定，针对该终端设备确定该报文所属的报文流的报文发送频率的方式，上述该终端设备基于该第一报文流频率信息确定报文流的报文发送频率的方式仅为示意性说明，本申请时候实施例并不限于此。例如，在该终端设备侧配置报文流的报文发送频率，该终端设备在发送报文之前，基于报文所属的报文流从该终端设备中配置的报文流的报文发送频率中确定该报文所属的报文流的报文发送频率。
在移动网络中，由于移动性的存在，每条传输通道在不同时段所支持的报文发送频率可能都不一样，因此，需要网络设备时时更新每条传输通道的报文发送频率，鉴于此，本申请实施例还提供了两种可选的实现方式，在一种可选的实现方式中，第三网络设备更新传输通道的报文发送频率，在另一种可选的实现方式中，该控制设备更新传输通道的报文发送频率。下面，分别对两种可选的实现方式分别进行说明。
方式A(第三网络设备更新传输通道的报文发送频率)
在步骤S231中，该控制设备向第三网络设备(为了便于区分与理解，记为网络设备#C)发送第二标识信息(为了便于区分与理解，记为标识信息#2)和第二报文流频率信息(为了便于区分与理解，记为报文流频率信息#2)，其中，该标识信息#2用于标识该传输通道#1，该报文流频率信息#2用于指示该至少一个报文流中每个报文流的报文发送频率，或，该报文流频率信息#2用于指示该至少一个报文流的报文发送频率的总和，并且，该网络设备#C接收该标识信息#2和该报文流频率信息#2。
其中，该标识信息#2为用于唯一标识该传输通道#1的标识信息，即，上文所述的传输通道第一类标识。
可选地，该网络设备#C为UDM网元。
在步骤S232中，该网络设备#C根据该标识信息#2，确定第一传输通道频率信息(为了便于区分与理解，记为传输通道频率信息#1)，该传输通道频率信息#1用于指示该传输通道#1当前所支持的报文发送频率。
例如，该网络设备#C中配置有整个移动网络中每个传输网络中配置的传输通道的传输通道信息，其中，每个传输通道的传输通道信息包括用于指示传输通道的报文发送频率的传输通道频率信息，那么，该网络设备#C根据该标识信息#2从传输通道信息中确定该传输通道#1的传输通道信息，进而，再从该传输通道#1的传输通道信息中确定该传输通道频率信息#1。
在步骤S233中，该网络设备#C根据该传输通道频率信息#1和该报文流频率信息#2，生成更新的传输通道频率信息#1。
其中，该网络设备#C可以分别根据两种情况更新传输通道频率信息#1，具体如下描述。
情况1(为该至少一个报文流预留报文发送频率)
在该情况1中，该网络设备#C需要从该传输通道#1的报文发送频率中为该至少一个报文流预留该至少一个报文流的报文发送频率。
例如，该控制设备在为该至少一个报文流选择该传输通道#1后，为了保证该至少一个报文流的报文以及后续其他报文流的报文的正确传输，该网络设备#C将该传输通道#1中被该至少一个报文流占用的报文发送频率减去，剩下的传输通道#1的报文发送频率用于其他报文流选择传输通道，即，在该控制设备基于更新的传输通道频率信息#1中的报文发送频率确定其他报文流是否可以使用该传输通道#1发送报文。
其中，该网络设备#C分别基于两种方式更新传输通道频率信息#1：
方式A1
当该报文流频率信息#2用于指示该至少一个报文流中每个报文流的报文发送频率时，该网络设备#C从该传输通道#1当前所支持的报文发送频率中减去该每个报文流的报文发送频率，生成该更新的传输通道频率信息#1。
方式A2
当该报文流频率信息#2用于指示该至少一个报文流的报文发送频率的总和时，该控制设备从该传输通道#1当前所支持的报文发送频率中减去该至少一个报文流的报文发送频率的总和，生成更新的传输通道频率信息。
其中，方式A2与方式A1不同之处在于，在方式A2中，该报文流频率信息#2表示的该至少一个报文流中所有报文流的报文发送频率的总和，可以使得该网络设备#C直接从该传输通道#1当前所支持的报文发送频率中减去该至少一个报文流中所有报文流的报文发送频率的总和，而在方式A1中，该报文流频率信息#2表示的是该至少一个报文流中每个报文流的报文发送频率，该网络设备#C需要从该传输通道#1当前所支持的报文发送频率中减去每个报文流的发送频率，或，减去该网络设备#C基于该至少一个报文流中的每个报文流的报文发送频率生成的报文发送频率的总和。
这里，该网络设备#C可以根据接收到的信息的类型确定情况1，即该网络设备#C是否需要为该至少一个报文流预留报文发送频率。例如，在会话过程中，该报文流频率信息 #2和该标识信息#2可以承载在传输通道请求信息中，这样，该网络设备#C可以基于该传输通道请求信息的信息类型就可以确定需要为该至少一个报文流预留资源，具体内容可以参考下文关于方法300中的步骤308的描述。
情况2(释放该至少一个报文流的报文发送频率)
在该情况2中，该网络设备#C需要在该传输通道#1的报文发送频率中加上该至少一个报文流中每个报文流的报文发送频率，这样，该控制设备基于更新的传输通道频率信息#1中的报文发送频率确定其他报文流是否可以使用该传输通道#1发送报文。
需要说明的是，在这种情况下，基于该标识信息#1确定的传输通道频率信息#1中的报文发送频率是在情况1中已经更新后的传输通道的报文发送频率。
同理，该网络设备#C分别基于两种方式更新传输通道频率信息#1：
方式A3
当该报文流频率信息#2用于指示该至少一个报文流中每个报文流的报文发送频率时，该网络设备#C从该传输通道#1当前所支持的报文发送频率中加上该每个报文流的报文发送频率，生成该更新的传输通道频率信息#1。
方式A4
当该报文流频率信息#2用于指示该至少一个报文流的报文发送频率的总和时，该控制设备从该传输通道#1当前所支持的报文发送频率中加上该至少一个报文流的报文发送频率的总和，生成更新的传输通道频率信息#1。
同理，该网络设备#C可以基于接收到的信息的类型来确定是否需要释放该至少一个报文流的报文发送频率。例如，在会话结束过程中，该报文流频率信息#2和该标识信息#2可以承载在传输通道释放信息，这样，该网络设备#C可以基于该传输通道释放信息的信息类型就可以确定需要释放该至少一个报文流的报文发送频率。
这样，后续控制设备需要基于所有传输通道的信息为其他会话的报文流确定对应的传输通道时，该网络设备#C可以将传输通道信息中更新的传输通道频率信息发送给该控制设备，为其他会话的报文流选择传输通道提供真实有效的数据。
方式B(控制设备也可以更新传输通道频率信息)
在另一种可选的实现方式中，该控制设备也可以更新传输通道频率信息。
可选地，该方法还包括：
该控制设备根据该第一传输通道，确定第一传输通道频率信息，该第一传输通道频率信息用于指示该第一传输通道当前所支持的报文发送频率；
该控制设备获取第二报文流频率信息，该第二报文流频率信息用于指示该至少一个报文流中每个报文流的报文发送频率，或，该第二报文流频率信息用于指示该至少一个报文流的报文发送频率的总和；
该控制设备根据该第一传输通道频率信息和该第二报文流频率信息，生成更新的第一传输通道频率信息。
可选地，该控制设备根据该第一传输通道频率信息和该第二报文流频率信息，生成更新的第一传输通道频率信息，包括：
当该第二报文流频率信息用于指示该至少一个报文流中每个报文流的报文发送频率时，该控制设备从该第一传输通道当前所支持的报文发送频率中减去该每个报文流的报文 发送频率，生成该更新的第一传输通道频率信息；或，
当该第二报文流频率信息用于指示该至少一个报文流中每个报文流的报文发送频率时，该控制设备从该第一传输通道当前所支持的报文发送频率中加上该每个报文流对应的报文发送频率，生成该更新的第一传输通道频率信息；或，
当该第二报文流频率信息用于指示该至少一个报文流的报文发送频率的总和时，该控制设备从该第一传输通道当前所支持的报文发送频率中减去该至少一个报文流的报文发送频率的总和，生成该更新的第一传输通道频率信息；或，
当该第二报文流频率信息用于指示该至少一个报文流的报文发送频率的总和时，该控制设备从该第一传输通道当前所支持的报文发送频率中加上该至少一个报文流的报文发送频率的总和，生成该更新的第一传输通道频率信息。其中，该控制设备更新该传输通道频率信息#1的具体过程与上文中该网络设备#C更新该传输通道频率信息#1的具体过程相同，此处不再赘述。
这里需要说明的是，控制设备可以根据当前步骤的具体内容确定是为该至少一个报文流预留报文发送频率还是释放该至少一个报文流的报文发送频率。例如，在会话过程中，该控制设备在为网络设备#A确定好传输通道后，就可以为该至少一个报文流预留报文发送频率。再例如，在会话结束后，该控制设备与UDM网元进行会话释放的流程，在此种情况下，该控制设备确定网络设备#A已经完成了会话，那么，该控制设备可以在会话释放的流程的过程中或会话释放的流程之后释放该至少一个报文流的报文发送频率。
因此，本申请实施例的传输信息的方法，控制设备通过向第三网络设备发送第二标识信息和第二报文流频率信息，可以使得该第三网络设备可以基于该第二标识信息和该第二报文流频率信息时时更新第一传输通道的报文发送频率，以能够真实反映该第一传输通道当前能够支持的报文发送频率，为其他报文流选择传输通道提供真实有效的数据，从而尽可能保证所有报文流的报文的正常传输。
需要说明的是，在本申请实施例中，上述仅以一条传输通道为例说明传输信息的方法，但这不应对本申请实施例构成任何限定。控制设备针对多条传输通道中每条传输通道有关的信息(例如，第一标识信息、第一指示信息、第二标识信息等)的生成以及传输过程可以与第一传输通道的有关的信息的生成以及传输过程的相同。并且，与多条传输通道有关的信息可以承载于同一个消息中，也可以分别承载于多个消息中。
以上，结合图2，从该控制设备与网络设备#A、终端设备和网络设备#C之间交互的角度对本申请实施例进行了详细说明。下面，分别结合图3至图6对本申请实施例在具体场景中的具体流程做一详细说明。
图3是根据本申请一实施例的传输信息的方法300的示意性流程图。在该方法300中，以SMF网元作为该控制设备，接入网设备、UPF网元或应用服务器中任一个作为该网络设备#A，UDM网元为该网络设备#C为例，描述了在会话建立的场景中，各个网元之间传输信息的过程。
此外，在该方法300中，该网络架构中还包括AMF网元、策略控制功能(policy control function，PCF)网元以及UDM网元。其中，将该接入网设备与该UPF网元之间的传输网络记为传输网络#A，将该UPF网元与该应用服务器之间的传输网络记为传输网络#B。

其中，传输通道信息中包括每个传输通道的相关参数，具体针对每条传输通道的参数的描述可以参考上文描述，此处不再赘述。
作为示例而非限定，在步骤S304中，该签约数据中也可以包括该传输通道信息，即，该SMF网元也可以从包括签约数据中获取该传输通道信，本申请实施例不做任何限定。
S306，该SMF网元为该会话的报文流，从传输网络#A中预配置的所有传输通道中确定对应于该会话的报文流的至少一条传输通道(为了便于区分与理解，记为传输通道组#A)，从传输网络#B中预配置的所有传输通道中确定对应于该会话的报文流的至少一条传输通道(为了便于区分与理解，记为传输通道组#B)。
其中，该SMF网元基于该会话的报文流在每个传输网络中确定对应的传输通道的过程可以参考上文关于基于至少一个报文流确定传输通道#1的过程，此处不再赘述。
例如，该会话的报文流包括3个报文流，报文流#1和报文流#2为上行报文流，报文流#3为下行报文流，在不同的传输网络中，分别为报文流#1和报文流#2确定用于上行传输的传输通道，为报文流#3确定用于下行传输的传输通道。在传输网络#A中，为3个报文流确定了两条传输通道，将这两条传输通道分别记为上行传输通道#A1和下行传输通道#A2，其中，该上行传输通道#A1用于传输属于报文流#1和报文流#2的报文，该下行传输通道#A2用于传输属于报文流#3的报文；在传输网络#B中，为3个报文流也确定了两条传输通道，将这两条传输通道分别记为上行传输通道#B1和下行传输通道#B2，其中，该上行传输通道#B1用于传输属于报文流#1和报文流#2的报文，该下行传输通道#B2用于传输属于报文流#3的报文。
S307，该SMF网元向该UDM网元发送传输通道请求消息。
其中，该传输通道请求消息中包括在每个传输网络中该会话的报文流中每个报文流的报文发送频率以及对应于每个报文流的传输通道的标识。

S309，该SMF网元向该应用服务器发送用于标识在传输网络#B中传输通道的至少一个标识信息和对应的至少一个指示信息。
其中，每个指示信息用于指示对应的传输通道传输的报文所属的报文流所属的至少一个报文流，具体针对标识信息和对应的指示信息的描述可以参考上文针对第一标识信息和第一指示信息的描述，此处不再赘述。
继续以上述例子为例进行说明，在传输网络#B中，应用服务器是下行传输的发送端，因此，该至少一个标识信息仅包括用于标识下行传输通道#B2的标识信息(为了便于区分与理解，记为下行传输通道标识信息#B2)，对应地，该至少一个指示信息包括对应于该下行传输通道标识信息#B2的指示信息(为了便于区分与理解，记为指示信息#B2)。
因此，该应用服务器可以基于该下行传输通道标识信息#B2和该指示信息#B2发送报文。具体发送报文的过程，可以参考上文针对网络设备#A发送基于第一指示信息和第一标识信息发送报文的过程，此处不再赘述。
S310，该应用服务器向该SMF网元发送确认消息，该确认消息表示该应用服务器成功接收SMF网元在步骤S309中发送的至少一个标识信息和对应的至少一个指示信息。
S311，该SMF网元向该UPF网元发送用于标识传输网络#A和传输网络#B中传输通道的至少一个标识信息和对应的至少一个指示信息。
例如，该SMF网元可以发送N4会话建立/修改请求(N4 session establishment/modification request)消息，该消息中包括用于标识传输网络#A和传输网络#B中传输通道的至少一个标识信息和对应的至少一个指示信息。
其中，每个指示信息用于指示对应的传输通道传输的报文所属的报文流所属的至少一个报文流，具体针对标识信息和对应的指示信息的描述可以参考上文针对第一标识信息和第一指示信息的描述，此处不再赘述。
继续以上述例子进行说明，在传输网络#A中，该UPF网元是下行传输的发送端，在传输网络#B中，该UPF网元是上行传输的发送端，因此，针对该UPF网元，该至少一个标识信息即包括用于标识下行传输通道#A2的标识信息(为了便于区分与理解，记为下行传输通道标识信息#A2)和用于标识上行传输通道#B1的标识信息(为了便于区分与理解，记为上行传输通道标识信息#B1)，对应地，该至少一个指示信息包括对应于该下行传输通道标识信息#A2的指示信息(为了便于区分与理解，记为指示信息#A2)和对应于该上行传输通道标识信息#B1的指示信息(为了便于区分与理解，记为指示信息#B1)。
S312，该UPF网元向该SMF网元发送确认消息，该确认消息表示该UPF网元成功接收该SMF网元在步骤S311中发送的至少一个标识信息和对应的至少一个指示信息。
例如，当步骤S311中用于标识传输网络#A和传输网络#B中传输通道的至少一个标识信息和对应的至少一个指示信息承载于N4 session establishment/modification request消息时，该确认消息可以是N4会话建立/修改响应(N4 session establishment/modification response)消息。
