下面结合附图对本发明作进一步详细描述。
为了便于理解，在介绍本发明之前，首先介绍现有技术的互联网架构。现有技术的互联网络包括：终端11以及多个转发设备12。
上述终端11与互联网中的其中一个转发设备12连接，转发设备12通过另一种方式(即与无线方式不同的连接方式)与接入互联网，上述无线方式包括但不限于：蓝牙、WIFI等方式，上述另一种方式可以为，LTE/LTE-A或有线方式。图1中以无线方式LTE为示例。
由于终端11只通过一个转发设备12接入到互联网中，如果该转发设备12出现了问题，则终端11的无法通过转发设备12发送与互联网进行通信。
为了解决上述问题，本发明对现有技术的互联网架构进行了改进。如图2所示，该互联网包括：终端10、第一转发设备20以及第二转发设备30。上述终端10通过无线方式分别与第一转发设备20以及第二转发设备30连接，第一转发设备20以及第二转发设备30通过另一种方式(即与无线方式不同的连 接方式)与接入物联网，上述无线方式包括但不限于：蓝牙、WIFI等方式，上述另一种方式可以为，LTE或有线方式。
物联网是利用局部网络或互联网等通信技术把传感器、控制器、机器、人员和物等通过新的方式联在一起，形成人与物、物与物相联，实现信息化、远程管理控制和智能化的网络。物联网是互联网的延伸，它包括互联网及互联网上所有的资源，兼容互联网所有的应用，但物联网中所有的元素(所有的设备、资源及通信等)都是个性化和私有化。
上述终端根据不同的情况可以具有不同的表现形式，终端11(例如，蜂窝电话或者智能电话)可以利用无线通信系统来发射和接收数据以用于双路通信。终端11可以包括用于数据发射的发射机以及用于数据接收的接收机。对于数据发射，发射机可以利用数据对发射本地振荡器(LO)信号进行调制以获得经调制的射频(RF)信号，对经调制的RF信号进行放大以获得具有恰当发射功率级别的输出RF信号，并且经由天线将输出RF信号发射给基站。对于数据接收，接收机可以经由天线来获得所接收的RF信号，放大并利用接收LO信号将所接收的RF信号下变频，并且处理经下变频的信号以恢复由基站发送的数据。终端11可以支持与不同无线电接入技术(RAT)的多个无线系统的通信(例如LTE/TE-A和NR)。每个无线系统可能具有某些特性和要求，能够高效地支持利用不同RAT的无线系统的同时通信。无线用户设备还可以被称为用户设备(UE)、移动台、终端、接入终端、订户单元、站点，等等。无线用户设备可以是蜂窝电话、智能电话、平板计算机、无线调制解调器、个人数字助理(PDA)、手持式设备、膝上型计算机、智能本、上网本、无绳电话、无线本地回路(WLL)站点、蓝牙设备，等等。在智能家居以及可穿戴设备高速发展的今天，终端11还可以是其也可以包含带有联网功能的其他设备，例如，智能电灯、智能电视、智能清扫设备、智能睡眠设备，智能监控设 备等，其表现的形式可以为多种多样，例如对于智能电灯，该智能电灯包括但不限于：智能台灯，智能吸顶灯，智能壁灯等设备，例如对于智能电视来说，其可以为三星牌智能电视，当然其也可以为夏普牌智能电视，例如对于智能清扫设备来说，其可以为，智能扫地机器人，当然其还可以包括智能吸尘器、智能垃圾处理器等设备，例如对于智能睡眠设备来说，其可以为：智能床垫、智能沙发等设备，例如对智能监控设备来说或，其可以为，智能血压计，智能温度计等，本发明对上述终端的具体形式以及数量或种类并不限定。终端11可以能够与无线系统进行通信，还可以能够从广播站、一个或多个全球导航卫星系统(GNSS)中的卫星等接收信号。终端11可以支持用于无线通信的一个或多个RAT，诸如GSM、WCDMA、cdma2000、LTE/LTE-A、802.11，等等。术语“无线电接入技术”、“RAT”、“无线电技术”、“空中接口”和“标准”经常可互换地被使用。
上述第一转发设备以及第二转发设备可以是路由器、交互机、中继站，或其他的具有无线连接以及数据转发功能的网络设备，本发明具体实施方式并不局限上述转发设备的具体表现形式。其中，交互机可以是二层交换机，也可以是三层交换机。可以理解的是，第一转发设备和第二转发设备可以是相同类型的设备，也可以是不同类型的设备。例如，第一转发设备和第二转发设备可以都是路由器，或者，第一转发设备是路由器，第二转发设备是中继器等等。
需要说明的是，终端11可以通过下行链路和上行链路与转发设备12进行通信。下行链路(或前向链路)是指从转发设备12到终端11的通信链路，而上行链路(或反向链路)是指从终端11到转发设备的通信链路。在LTE/LTE-A方式中，上/下行载波分别采用SC-FDMA(Single-carrier Frequency-Division Multiple Access，单载波频分多址)/OFDM(Orthogonal Frequency Division Multiple Access正交频分多址)以及CP(Cyclic Prefix循环前缀)。在5G标准中， 示例性的，可以对上下行载波进行统一，即上行链路与下行链路均采用OFDM以及CP。
为了解决第一转发设备在负载比较重，或者在发生故障时，会导致整个终端都无法正常进行数据传输的问题，本发明基于图2所示的互联网结构，提出了一种转发设备切换方法，如图3所示，本发明实施例的转发设备切换方法包括如下步骤：
310：第一转发设备检测第一转发设备与终端之间的数据在物联网的网络传输速率，其中，终端连接到第一转发设备。
终端和第一转发设备之间的数据的网络传输速率取决于终端和第一转发设备之间的上行网络传输速率以及下行网络传输速率的总和。其中，上行网络传输速率通常是指终端向第一转发设备发送的数据的传输速率，下行网络传输速率通常是指第一转发设备向终端发送的数据的传输速率。当然，在其他的实施例中，上行网络传输速率和下行网络传输速率也可以是相反的定义。第一转发设备分别检测第一转发设备与终端之间的数据的上行网络传输速率以及下行网络传输速度，并根据第一转发设备与终端之间的数据的上行网络传输速率以及下行网络传输速度确定第一转发设备与终端之间的数据的网络传输速率。如果第一转发设备与终端之间的数据的网络传输速率大于或者等于预设速度，说明第一转发设备正常工作，保持第一转发设备正常工作即可；如果第一转发设备与终端之间的数据的网络传输速率小于预设速度，说明第一转发设备可能出现了故障，进入步骤320。
可以理解的是，终端和第一转发设备之间的无线连接方式包括但不限于：蓝牙、WIFI等方式，此外，终端和第一转发设备之间的无线连接方式还可以是2G、3G、4G甚至未来的5G方式或有线方式。
320：第一转发设备自动恢复出厂设置。
在本发明实施例中，第一转发设备恢复出厂设置的方式可以包括硬件复位以及软件复位。其中，出厂设置即第一转发设备出厂时的默认状态，如开始界面，待机方式，操作快捷键，定时提醒等功能在出厂时的默认状态，但不会删除存储的数据。硬件复位是指将所有第一转发设备中的硬件参数恢复到初始值，软件复位是指将软件程序指向第一转发设备中运行的软件的第一条指令，本发明并不限制上述恢复出厂设置的具体表现形式。通过将第一转发设备自动恢复出厂设置，就有可能解决部分故障问题。
330：第一转发设备判断自动恢复出厂设置是否失败。如果第一转发设备判断自动恢复出厂设置成功，则第一转发设备的故障可以被修复，则终端可以继续通过第一转发设备接入到互联网中；如果第一转发设备判断自动恢复出厂设置失败，则第一转发设备的故障依然存在，终端无法通过第一转发设备接入到互联网中，进入步骤340。
340：第一转发设备向终端发送切换命令。
在本发明实施例中，第一转发设备在下行控制信令中携带切换命令。在一具体实施例子，第一转发设备在最近的一个下行控制信令中携带切换命令。在另一个具体的实施例中，为了避免切换命令丢失而没有被终端所接收，第一转发设备可以在多个下行控制信令中重复发送切换命令，以确保切换命令能被终端所接收，也即是说，所述第一转发设备可以通过重复发送所述切换命令来确保所述终端能够成功接收到所述切换命令，最终成功进行切换。
350：第一转发设备将终端切换至第二转发设备。
在本发明实施例中，如果第一转发设备通过自动恢复出厂设置也未能修复故障，则第一转发设备可以向终端发送切换命令，以使得终端基于切换命令切换至第二转发设备，其中，第二转发设备是第一转发设备的备用转发设备。
第二转发设备是第一转发设备的备用转发设备可以理解为：(1)第二转发设备平时不任何承载转发业务，第二转发设备只作为第一转发设备的备用，当第一转发设备出现故障时，将第一转发设备承载的转发业务转移到第二转发设备中，第二转发设备只承担第一转发设备转移的转发业务。(2)第二转发设备平时还承载其他的转发业务，当第一转发设备出现故障时，将第一转发设备承载的转发业务转移到第二转发设备中，第二转发设备同时承担第一转发设备转移的转发业务和其他的转发业务。
当终端通过有线的方式连接第一转发设备以及第二转发设备时，终端将会通过不同的端口分别连接第一转发设备以及第二转发设备。例如，终端通过第一端口连接第一转发设备，终端通过第二端口连接第二转发设备。第一转发设备向终端发送切换指令，终端接收到切换指令后，基于切换命令将通过第一端口与第一转发设备传输数据切换为通过第二端口与第二转发设备传输数据。
当终端通过无线的方式连接第一转发设备以及第二转发设备时，如果第一转发设备的备用转发设备的数量不止一个，则第一转发设备向终端发送的切换命令中包括第二转发设备的标识，终端接收切换命令后，从切换命令中获取得到第二转发设备的标识，并基于第二转发设备的标识切换至第二转发设备。本发明实施例中，所述第二转发设备的标识可以是第二转发设备的无线网络临时标识(Radio Network Temporary Identity，RNTI)，也可以是第二转发设备的MAC地址，还可以是其他能够使辨识出第二转发设备的标识信息，这里不做限制。
可以理解的是，第一转发设备的备用转发设备的数量可以是一个，也可以是多个。当第一转发设备的备用转发设备的数量为多个时，终端可以从多个转发设备中任意选择一个备用转发设备作为第二转发设备。当然，终端也可以根据对备用转发设备的测量结果，从多个备用转发设备中选择最优或者较优的一 个备用转发设备作为第二转发设备。
在一些可能的实现方式中，所述候选中继设备的测量结果可包括：所述备用转发设备与终端之间的信号强度、备用转发设备的负载能力(例如数据缓冲能力、剩余电量等)、备用转发设备的当前负载量、信息安全处理(加解密)能力等等。实际应用中，基站可以根据该测量结果为所述终端选取出最优或较优的备用转发设备，将选取出的备用转发设备作为终端的第二转发设备。
