本申请提供的通信方法在上述任意通信系统的场景下，可以适用于任一回传系统，尤其适用于无线回传系统。
图1是本申请的实施例应用的无线回传系统100的架构示意图。如图1所示，以车辆中设备与网络设备进行通信的场景为例，该无线回传系统100包括车地回传子系统110、车载接入子系统120和核心网子系统130。其中，车地回传子系统110分别与车载接入子系统120和核心网子系统130通过无线的方式连接，实现将车载接入系统120接入网络进行上下数据回传。
结合图1所示，车地回传子系统110包括接入设备111和回传基站112。其中，接入设备111可以包括一个或者多个车载接入单元(Train Access Unit，TAU)，如图1中的TAU 111-1和TAU 111-2。可选的，回传基站112可以包括基带处理单元(base band unit，BBU)1121和有源天线处理单元(active antenna unit，AAU)1122，AAU 1122的数量可以是多个，如图1中的1122-1和1122-2，且多个AAU 1122可以均匀分布。例如，当车辆运行于隧道内时，AAU可以沿车辆行驶方向间隔性的均匀部署于隧道壁上。
可选的，多个AAU 1122可以划分为多个AAU组，AAU组中的多个AAU可以与车辆中部署的多个TAU一一对应。结合图1所示，AAU 1122-1和1122-2为一个AAU组，当车辆在图1中由左至右行驶时，AAU 1122-1与车尾处的TAU 111-1进行通信，AAU 1122-2可以与车头处的TAU 111-2通信。
结合图1所示，车载接入子系统120包括车载回传路由器121、车载基站122和 终端设备123。其中，车载基站122为车辆中的设备提供网络服务，车载回传路由器121可以为上行数据传输选择不同的接入设备(例如上述TAU 111-1或TAU 111-2)。

其中，可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
此外，终端设备123还可以是物联网(Internet of things，IoT)系统中的终端设备。IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。IoT技术可以通过例如窄带(narrow band，NB)技术，做到海量连接，深度覆盖，终端省电。
此外，终端设备123还可以包括智能打印机、车辆探测器等传感器，主要功能包括收集数据(部分终端设备)、接收网络设备的控制信息与下行数据，并发送电磁波，向网络设备传输上行数据。等等。

回传核心网路由器131可以将下行数据在车载基站核心网133以及回传核心网132之间透传，并为下行数据选择不同接入设备(例如TAU 131)进行数据回传。
回传核心网132与接入设备111(例如上述TAU 111-1和/或TAU 111-1)建立连接、对接入设备111进行管理以及对业务完成承载建立，作为承载网络提供到外部网络的接口。
车载基站核心网133提供与上述终端设备123的连接，对终端设备123进行管理以及对业务完成承载建立。
应理解，上述无线回传系统100仅为一种示例，无线回传系统100可以包括比图1中更多或者更少的部件。
还应理解的是，上述无线回传系统100中的车辆也可以是火车、汽车、无人驾驶车辆等，或者车辆也可以替换为飞机、船舶、智能机器人等任意可移动的设备。
还应理解的是，上述无线回传系统100中车辆在隧道内行驶仅为一种示例，但不应对本申请构成任何限定，例如车辆还可以行驶于地面上，当车辆替换为飞机时可以行驶于空中，当车辆替换为船舶时可以行驶与水面，相应的，上述AAU 1122也可以 部署于陆地上、空中、水面等，本申请对此不作限定。
网络设备(如图1中的任一基站、路由设备、网关等)和终端设备之间以及终端设备和终端设备之间可以通过授权频谱(licensed sPectrum)进行通信，也可以通过免授权频谱(unlicensed sPectrum)进行通信，也可以同时通过授权频谱和免授权频谱进行通信。网络设备和终端设备之间以及终端设备和终端设备之间可以通过6G以下的频谱进行通信，也可以通过6G以上的频谱进行通信，还可以同时使用6G以下的频谱和6G以上的频谱进行通信。本申请的实施例对网络设备和终端设备之间所使用的频谱资源不做限定。
应理解，本申请对于网络设备和终端设备的具体形式均不作限定。
在上述图1所示的无线回传系统100中，一方面，车辆在行驶过程中，TAU(如TAU 111-1或111-2)与回传基站112之间的回传链路的信道是实时变化的，在小区切换过程中，回传能力存在突变，当这种突变发生时，终端设备与网络设备之间的传输无法满足业务需求，导致终端设备的通信质量较差。
另一方面，结合图2所示，目前TAU1和TAU2的回传链路独立，各TAU分别连接各自的BBU，那么速率波动容易导致回传链路中传输的数据超出链路承载能力。
针对上述问题，本申请实施例中路由设备与各接入设备连接，通过接入设备向路由设备上报回传链路的吞吐率，使路由设备根据每个接入设备上报的吞吐率确定数据传输采用的接入设备，合理利用多个接入设备对应的回传链路的传输资源，例如图2中的TAU1和TAU2的速率波动互相弥补，避免部分TAU承载的传输数据不饱和而另一部分TAU承载的传输数据超出承载能力，也即实现可动态调整回传链路路由，进而提高了回传链路的可靠性。
其中，路由设备根据各接入设备上报的吞吐率确定接入设备，也可以表述为路由设备根据各接入设备上报的吞吐率选择一个接入设备进行数据传输，下文中“确定”与“选择”交替使用，二者所表达的含义相同。
下面将结合附图对本申请实施例提供的通信方法进行说明。
应理解，下文仅为便于理解和说明，以接入设备与路由设备(包括第一路由设备和或第二路由设备)之间的交互为例详细说明本申请实施例所提供的方法。该接入设备例如可以是图1中的接入设备111(如可以是TAU111-1和TAU111-2)，第一路由设备例如可以是图1中的车载路由器121，第二路由设备例如可以是图1中的回传核心网路由器131。
但应理解，这不应对本申请提供的方法的执行主体构成任何限定。只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法，便可以作为本申请实施例提供的方法的执行主体。例如，下文实施例所示的接入设备也可以替换为该接入设备中的部件，比如芯片、芯片系统或其他能够调用程序并执行程序的功能模块。路由设备也可以替换为该路由设备中的部件，比如芯片、芯片系统或其他能够调用程序并执行程序的功能模块等。
还应理解的是，第一路由设备可以集成于接入设备，换言之，接入设备可以集成于第一路由设备。
图3是本申请实施例提供的通信方法200的示意性流程图。如图2所示，该方法 200可以包括S210至S230-1。下面对方法200中的各步骤做详细说明。
S210，接入设备确定回传链路在第一时刻的第一吞吐率，该第一吞吐率包括上行吞吐率和/或下行吞吐率，该上行吞吐率用于确定终端设备上行传输采用的接入设备，该下行吞吐率用于确定终端设备下行传输采用的接入设备；

上行吞吐率可以反映回传链路的上行回传速率能力，下行吞吐率可以反映回传链路的下行回传速率能力。可选的，第一时刻可以是当前时刻，也可以晚于当前时刻，当第一时刻晚于当前时刻时，第一吞吐率可以是基于当前测量值的预测结果。
本申请实施例中接入设备和第一路由设备均为了实现终端设备与网络设备之间的通信，或者终端设备通过网络与其他终端设备之间的通信，换言之，终端设备在接入设备与第一路由设备的辅助下，能够向网络设备发送上行数据(也即上行传输)，或者接收网络设备发送的下行数据(也即下行传输)。
在S210的一种实现方式中，接入设备可以根据回传链路在第一时刻的参考信号接收功率，确定第一吞吐率。需要说明的是，参考信号接收功率可以是接入设备在第一时刻测量得到的，该参考信号接收功率通常可以用SSB RSRP表示，即同步信号块(synchronization signal block，SSB)上测量到的参考信号接收功率(reference signal receiving power，RSRP)。
下面针对第一时刻为当前时刻或者第一时刻晚于当前时刻分别进行说明：
方式一、第一时刻为当前时刻时，上述S210包括以下部分或者全部过程：
S211，接入设备可以根据参考信号接收功率确定调制阶数；
S212，接入设备根据调制阶数、调制阶数对应的码率以及接入设备被配置的资源粒子(Resource element，RE)，确定第一吞吐率。
在上述S211的一种实现方式中，接入设备可以根据参考信号接收功率和第一对应关系，确定与参考信号接收功率对应的调制阶数，该第一对应关系为参考信号接收功率和调制阶数的对应关系。可选的，第一对应关系可以是预设的、网络设备配置的，或者第一对应关系可以是接入设备根据历史数据生成的。示例性的，该历史数据可以是接入设备自身存储的，历史数据中包括多个历史时刻下通信时的SSB RSRP和调制阶数，参见表1所示，每个SSB RSRP的值对应一个调制和编码机制(modulation and coding scheme，MCS)索引(Inndex)I MCS，每个MCS索引在MCS映射关系中具有唯一对应的调制阶数(Modulation Order)Q m。
表1
SSB RSRP MCS索引
-80 27
-83 25
-87 22
MCS映射关系可以参见如下表2所示：
表2
Figure PCTCN2022121897-appb-000001
可以理解的是，MCS映射关系可以包括比上述表2更多或者更少的项(列)，例如还可以包括目标码率、频谱利用率等。
如表2所示，在MCS对应关系中，MCS索引不仅与调制阶数一一对应，MCS索引还与码率一一对应，调制阶数与码率一一对应。那么，接入设备可以根据第一对应关系确定与回传链路在第一时刻的参考信号接收功率对应的调制阶数和码率。
进一步地，在上述S212中，接入设备可以根据S211中确定调制阶数、该调制阶数对应的码率和接入设备被配置的RE，确定第一吞吐率。
例如，接入设备可以对第一RE数、数据流数、该调制阶数和该调制阶数对应的码率进行求积，再将乘积与时间单元的时长求商，得到上行吞吐率。通过公式表述如下：
上行吞吐率＝第一RE数*数据流数*码率*调制阶数/时间单元的时长。
再例如，接入设备可以对第二RE数、数据流数、该调制阶数和该调制阶数对应的码率进行求积，再将乘积与时间单元的时长求商，得到上行吞吐率。通过公式表述如下：
下行吞吐率＝第二RE数*数据流数*码率*调制阶数/时间单元的时长。
需要说明的是，第一RE数和第二RE数均可以根据接入设备被配置的RE确定。例如，第一RE数为接入设备被配置的RE数与上行开销RE数之差，第二RE数为所述接入设备被配置的RE数与下行开销RE数之差。上行开销RE数例如可以包括用于上行传输的公共信道、导频信号开销，下行开销RE数例如可以包括用于下行传输的公共信道、导频信号开销。可选的，上行开销RE数可以为第一预设值，例如预设为被配置的RE数的25％，类似的，下行开销RE数可以为第二预设值，例如预设为被配置的RE数的20％。
数据流数，也可以称作秩(RANK)数，可以是根据信道条件测量值确定的。可选的，该数据流数可以是预设数据流数，例如数据流数为2。
时间单元可以是时隙、子帧、无线帧等的时长。本实施例中时间单元可以是时隙，时间单元的时长也即每个时隙的时长，例如可以是0.125ms。
接入设备被配置的RE数可以根据配置信息确定，例如RE数＝每个时隙符号数*每载波资源块(Resource Block，RB)数*每个RB子载波数*载波数。每个时隙符号数例如为14个，每载波RB数例如为66个，每个RB子载波数例如为12个，载波数例如可配置1个，2个，4个或者8个。
方式二、第一时刻晚于当前时刻时，上述S210包括以下部分或者全部过程：
S213，接入设备根据当前时刻测量的参考信号接收功率和路径损耗函数，确定第一时刻的参考信号接收功率；
S211，接入设备可以根据参考信号接收功率确定调制阶数；
S212，接入设备根据调制阶数、调制阶数对应的码率以及接入设备被配置的RE，确定第一吞吐率。
在上述S213中，接入设备需要基于当前时刻的参考信号接收功率预测第一时刻的参考信号接收功率。
结合图4所示，假设接入设备按照预设的周期获取参考信号接收功率，当前时刻 为t2时刻，第一时刻即为t3时刻，那么第一时刻的参考信号接收功率F(t3)满足以下公式：
F(t3)＝F(t2)+Pathloss[(t3-t2)*v]
其中，F(t2)为当前时刻的参考信号接收功率，v表示车辆行驶速度，Pathloss为车辆行驶无线链路的路径损耗函数，以地铁隧道场景为例，校正后的隧道场景函数Pathloss＝32.4+20*log10(f)+19*log10(d)，其中f表示接入设备和网络设备所处的工作频点，单位为GHz，d表示距离，d＝(t3-t2)*v。
在一些实施例中，接入设备可以根据历史时刻的参考信号接收功率确定F(t)函数为单调递增函数或者单调递减函数，根据F(t)函数为递增或者递减，基于不同的公式预测第一时刻的参考信号接收功率。例如图4中t1时刻的参考信号接收功率F(t1)小于F(t2)，则F(t)函数为单调递增函数，第一时刻的参考信号接收功率F(t3)满足以下公式：F(t3)＝F(t2)+Pathloss[(t3-t2)*v]；若t1时刻的参考信号接收功率F(t1)大于F(t2)，则F(t)函数为单调递减函数，第一时刻的参考信号接收功率F(t3)满足以下公式：F(t3)＝F(t2)-Pathloss[(t3-t2)*v]
应理解的是，Pathloss函数的系数可以根据不同的环境条件调整。
进一步的，接入设备根据预测得到的第一时刻的参考信号接收功率，确定对应的调制阶数，进而确定第一吞吐率。
本申请实施例中S211和S212与上述方式一中的S211和S212以及各实现方式相同，此处不再赘述。
针对上述S220需要说明的是，接入设备与路由设备第一路由设备可以通过有线的方式连接，接入设备将所述第一吞吐率，以有线传输的方式发送给所述路由设备。
示例性的，接入设备按照链路发现协议(link layer discovery protocol，LLDP)中的标签长度值(tag length value，TLV)格式生成第一信息，该第一信息包括第一指示信息，第一指示信息用于指示第一信息是否包含上行吞吐率和/或下行吞吐率，在第一指示信息指示第一信息包含上行吞吐率的信息时，第一信息还包括上行吞吐率的信息，在第一指示信息指示包含下行吞吐率时，第一信息还包括下行吞吐率的信息；进一步地，接入设备将该第一信息发送给所述第一路由设备。
接入设备可以按照LLDP新增TLV信源(例如系统功能(System Capabilities)字段)中写入上行吞吐率的信息和/或下行吞吐率的信息。例如，在TLV中的保留位
(Reserved)中增加序号9，用于表示上行吞吐率和/或下行吞吐率。参见如下表3。
表3
Figure PCTCN2022121897-appb-000002
可选的，接入设备可以按照LLDP的发送间隔发送第一信息，或者可以按照预设间隔发送第一信息，例如预设发送间隔可以为1s。
需要说明的是，接入设备按照LLDP向路由设备发送吞吐率仅为一种示例，并不对本申请构成任何限定，接入设备还可以采用其他协议或者自定义传输写进行信息传输，本申请对此不作限定。
应理解，本申请实施例以接入设备与第一路由设备之间通过有线的方式为例进行说明，但并不对本申请构成任何限定。例如本申请实施例中接入设备和第一路由设备之间仍然可以通过无线的方式连接。
针对上述S230-1需要说明的是，第一路由设备可以获取多个接入设备各自发送的上行吞吐率，例如图1中第一路由设备可以接收TAU 111-1和TAU 111-2分别上报的上行吞吐率，并选择其中上行吞吐率较高的TAU作为终端设备上行传输采用的接入设备；或者，第一路由设备可以将各接入设备发送的上行吞吐率作为接入设备选择的一个判断因子，与其他维度的判断因子一起，综合确定终端设备上行传输采用的接入设备。
本申请实施例中，接入设备确定回传链路在第一时刻的第一吞吐率，并向第一路由设备发送该第一吞吐率，使第一路由设备根据该回传链路在第一时刻的上行吞吐率，确定上行传输采用的接入设备，实现了对回传链路路由的动态调整，减少了无线回传速率的波动，提升了回传链路的可靠性。
图5是本申请实施例提供的通信方法300的示意性流程图。如图5所示，该方法300可以包括S210至S240。下面对方法300中的各步骤做详细说明。
S210，接入设备确定回传链路在第一时刻的第一吞吐率，该第一吞吐率包括上行吞吐率和/或下行吞吐率，该上行吞吐率用于确定终端设备上行传输采用的接入设备，该下行吞吐率用于确定终端设备下行传输采用的接入设备；
S220，接入设备将该第一吞吐率发送给第一路由设备。
相应的，第一路由设备获取回传链路在第一时刻的第一吞吐率；
S230-2，第一路由设备将该第一吞吐率中的下行吞吐率发送至第二路由设备。
相应的，第二路由设备获取回传链路在第一时刻的下行吞吐率；
S240，第二路由设备根据该下行吞吐率，确定终端设备下行传输采用的接入设备。
上述S210和S220与图3所示的S210和S220相同，并且具有与图3中S210和S220各相同的实现方式，此处不再赘述。
在S230-2中，作为一种示例，第一路由设备按照路由封装协议进行数据封装，得到第一数据包，该第一数据包的包头包括下行吞吐率的信息，并将第一数据包发送至第二路由设备。
第一路由设备与第二路由设备之间以无线方式连接。第一路由设备例如可以通过通用路由封装(generic routing encapsulation，GRE)协议将下行吞吐率传输给第二路由设备。
例如，第一路由设备可以使用GRE头的Reserved1字段传递下行吞吐率。第一路由设备收到接入设备发送的第一吞吐率后，将下行吞吐率封装进上行数据包(即第一数据包)的GRE头中的Reserved1字段。第二路由设备从接收报文的GRE头中提取 下行吞吐率。
可选的，Reserved1字段为16bit。
第一路由设备可以将第一吞吐率中的上行吞吐率和下行吞吐率一同发送给第二路由设备，其封装以及传输过程与上述封装以及传输过程类似，此处不再赘述。
结合图6所示，无线回传系统中，下行业务数据流的传输可以包括如下部分或者全部过程：
Step1：车载基站核心网提供按照通用分组无线业务隧道协议用户面(general packet radio service tunneling protocol userplain，GTP-U)格式进行封装，封装后的数据包包含传输地址以及端口号。
Step2：第二路由器在GTP-U数据包上封装GRE协议包头。
Step3：回传核心网将GRE数据包作为有效载荷(payload)，再次进行GTP-U数据包封装。
Step4：回传基站收到GTP-U数据，并解包后，通过无线信道发给接入设备(例如TAU)，接入设备再透传给第一路由设备。
Step5：第一路由设备解析GRE的数据包头后，将数据转发给车载基站。
Step6：车载基站解析GTP-U包头，将数据发送给终端设备。
在上述S240中，第二路由器根据下行吞吐率进行非等价负载分担，换言之，第二路由设备根据每个接入设备的下行吞吐率，将待传输的业务数据分别选择相同或者不同的接入设备传输给终端设备。
第二路由设备可以根据多个接入设备各自发送的下行吞吐率，例如图1中第二路由设备可以接收由第一路由设备转发的TAU 111-1和TAU 111-2分别上报的下行吞吐率，并选择其中下行吞吐率较高的TAU作为下行传输采用的接入设备；或者，第二路由设备可以将各接入设备发送的下行吞吐率作为接入设备选择的一个判断因子，与其他维度的判断因子一起，综合确定下行传输采用的接入设备；或者，第二路由设备可以根据待传输的下行数据的业务类型和接入设备上报的下行吞吐率，选择对应的接入设备，例如第二路由设备在待传输的下行数据为视频时选择下行吞吐率较高的接入设备，在待传输的下行数据为文件时选择下行吞吐率较低的接入设备。
本申请实施例中，接入设备确定回传链路在第一时刻的第一吞吐率，并向第一路由设备发送该第一吞吐率，第一路由设备将第一吞吐率或者第一吞吐率中的下行吞吐率发送给第二路由设备，使第二路由设备根据该回传链路在第一时刻的下行吞吐率，确定下行传输采用的接入设备，实现了对回传链路路由的动态调整，减少了无线回传速率的波动，提升了回传链路的可靠性。
在上述任一实施例的基础上，为了防止传输过程中出现丢包，第二路由设备可以在下行数据传输的过程中，对待传输的多个下行数据包增加序号，例如在GRE封装过程中，通过GRE包头的封包序号(Sequence Number)字段指示每个下行数据包的序号，第一路由设备接收到该多个下行数据包后，可以按照各下行数据包的序号进行重排。
可选的，为了提高处理效率，第二路由设备可以根据待传输的下行数据包的业务优先级确定是否对其添加序号，例如第二路由设备可以针对服务质量(quality of service， QoS)要求高的业务对应的数据包添加序号。示例性的，大文件下载、网页浏览等业务，允许丢包，QoS要求较低，即业务优先级较低，而语音、游戏等业务对丢包的容忍度较低，QoS要求较高，也即业务优先级较高。
与下行传输类似的，第一路由设备可以在上行数据传输的过程中，对待传输的多个上行数据包增加序号，例如在数据包的封装过程中，通过GRE包头的Sequence Number字段指示每个上行数据包的序号，第二路由设备接收到该多个上行数据包后，可以按照上行数据包的序号进行重排。
与下行传输类似的，第一路由设备可以针对QoS要求高的业务，也即业务优先级为高优先级的上行数据包添加序号。
