图3为本公开一实施例所提供的无线通信模块在IoT模式的通信过程示意图；以及
图4为本公开一实施例所提供的通信装置的结构示意图。
详述
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
请参考图1，图1为本公开一实施例所提供的通信方法的流程图，该方法包括：
S101：判断在预设定时器时间内是否接收到通信状态指示消息主机侧下发的通信状态指示消息；
S102：若在所述预设定时器时间内接收到所述通信状态指示消息，确认所述终端设备处于正常工作状态，基于所述通信状态指示消息和第一SIM卡建立所述无线通信模块与云服务器的无线通信；以及
S103：若在所述预设定时器时间内未接收到所述通信状态指示消息，确认所述终端设备处于离线工作状态，利用第二SIM卡建立所述 无线通信模块与所述云服务器的无线通信。
本公开实施例可以应用于包含无线通信模块的终端设备，该通信状态指示消息可以用于指示当前终端设备的通信状态或者所处的通信状态。在此对于该通信状态指示消息的具体类型和内容不作限定。在某些实施方案中，可以采用MBIM消息，MBIM信息指Mobile Broadband Interface Model(移动宽带接口模型)消息，可以用来反馈移动通信状态。步骤S101可以在任意时刻执行，从而对终端设备进行检测，以调整终端设备的工作状态。
在此对于预设定时器时间不作限定，其可以由本领域技术人员设定，例如为1分钟、3分钟等等。当然，步骤S101默认在执行步骤S101前可由本领域技术人员对该预设定时器时间进行设置。
在步骤S101中，需要对预设定时器时间对判断是否接收到的通信状态指示消息主机侧下发的通信状态指示消息，该过程的执行主体可以为终端设备中与通信方式相关的模块，例如无线通信模块，或者通信模块的控制模块等等。
在步骤S102中，若在所述预设定时器时间内接收到所述通信状态指示消息，即确定终端设备处于移动宽带连接过程中，则终端设备处于正常工作状态，此时可以直接根据通信状态指示消息建立无线通信。
在建立无线通信的过程中，可以包括注网过程和拨号连接等过程。
在某些实施方案中，一种可行的执行方式如下：
S102A：若在所述预设定时器时间内接收到所述通信状态指示消息，发送***在线事件；
S102B：根据所述***在线事件确认所述终端设备处于正常工作状态；
S102C：利用协议栈基于所述通信状态指示消息进行网络注册；
S102D：在网络注册成功后，将所述无线通信模块作为MQTT客户端，并基于MQTT协议向云服务器发起拨号连接；
S102E：在所述拨号连接成功后，建立所述无线通信模块与云服务器的无线通信。
上述过程中，以无线通信模块为执行主体为例，在终端设备上电 启动后，若在预设定时器时间内若接收到通信状态指示消息，可以得到包含注网Register，拨号连接等控制消息，将这些控制信息发送至协议栈以实现无线网络连接。
此时无线通信模块可以发送***在线事件至终端设备中配置为执行设备模式管理的设备模式管理子功能，设备模式管理子功能接收到***在线事件后，确认无线通信模块处于在线状态，可以采用移动宽带模式运行。
协议栈接收到控制信息后，需要执行注网，并执行拨号连接，在注网成功后，会接收到注网成功消息。此时，可以将无线通信模块作为MQTT客户端，以便采用MQTT协议发起至云服务器的拨号连接，在拨号连接建立后，无线通信模块将与云服务器建立无线通信连接。MQTT客户端是应用MQTT协议的通信端，MQTT协议为Message Queuing Telemetry Transport，即消息队列遥测传输，是一种基于客户端-服务器的消息发布/订阅传输协议。
当然，在实际执行无线通信模块与云服务器的无线通信时，本领域技术人员还可以参考上述过程采用其他协议，在此不一一举例限定。
一旦在预设定时器时间内未接收到通信状态指示消息，表明此时终端设备未执行移动宽带连接，则终端设备处于离线工作状态。需要注意的是，该离线工作状态指在预设定时器时间内未接收到通信状态指示消息时所视为的终端设备的运行状态，并不代表终端设备当前真实的运行状态。通常该离线工作状态为终端设备进行休眠或者关机状态，此时终端设备的硬件处于断电状态，则相应的无线通信模块也处于断电状态，此时诊断设备处于离线工作状态。
在步骤S103中，在终端设备处于离线工作状态时，利用第二SIM卡建立无线通信模块与云服务器的无线通信。在此对于第二SIM卡不作具体限定，其余第一SIM卡为在不同通信模式中应用的SIM卡。一种优选的执行方式中，该第二SIM卡可以为内置eSIM卡。在利用第二SIM卡建立与云服务器的无线通信时，可以应用各种IoT协议。需要说明的是，在任意时刻仅能有一张SIM卡处于工作状态。
在某些实施方案中，以Windows操作***为例说明，Windows操 作***的无线网络连接基于DSSA(Dual SIM Single Active，双卡单激活)方式，无线通信模块同样基于DSSA方式，即Windows OS和无线通信模块都是基于双卡单待方式工作，此时双卡可以采用终端设备外置的USIM卡和无线通信模块内置的eSIM卡。
若执行步骤S103之前，还可以先通过集成在终端设备主机侧上的嵌入式控制器为无线通信模块供电，并将终端设备的当前运行模式由移动宽带模式切换至IoT模式，并将当前应用的SIM卡由第一SIM卡切换至第二SIM卡。
此外，也可以通过事件确认无线通信模块的状态。在某些实施方案中，可以生成***离线事件，一旦接收到***离线事件，则可以确定无线通信模块处于离线状态。从而可以切换终端设备的运行模式，并切换应用的SIM卡。
此后可以激活所述第二SIM卡的预置文件，利用预置文件执行网络注册流程，并在网络注册成功后建立网络连接。
在此对于如何利用预置文件执行网络注册流程不作限定，其可以包括如下步骤：
基于预置文件向协议栈发送网络注册请求；
在协议栈注网成功后，接收到注册成功消息；以及
根据注册成功消息将无线通信模块通过预设无线通信协议连接至云服务器。
由上述过程可以看出，同样可以借助协议栈进行注网，同时在注网成功后，将无线通信模块作为MQTT客户端并基于MQTT协议发起至云服务器的拨号连接，以实现终端设备的IoT应用。
为了便于终端设备使用，可以将终端设备的移动宽带模式设为默认运行模式。如此在终端设备正常运行时，默认采用移动宽带模式，一旦检测到预设定时器时间内未接收到通信状态指示消息，可以切换至离线工作状态，进入IoT模式。
本公开实施例可以通过检测预设定时器时间内是否接收到通信状态指示消息主机侧下发的通信状态指示消息判断终端设备的当前工作状态，并根据终端设备的当前工作状态采用不同的连接方式建立与云 服务器的连接，确保终端设备在任何工作状态均保持云端连接，能够满足用户使用需求，确保终端设备的高可用性。
请参见图2，图2为本公开一实施例所提供的终端设备在MBB模式的通信过程示意图，该过程为在MBB模式下的通信过程，以通信过程中涉及的子功能和具体的组件对具体的通信过程进行描述，可以包括：
终端设备上电启动后，无线通信模块将会接收到通信状态指示消息主机侧下发的通信状态指示消息，包括注网Register，拨号Connect等控制消息，无线通信模块的通信状态指示消息处理(MBIM Message Handler)子功能将控制消息发送给协议栈(Cellular Protocol Stack)以建立无线网络连接；
通信状态指示消息处理子功能接收到通信状态指示消息，将给设备模式管理(Device Mode Manager)子功能发送***在线事件；
终端设备启动后，设备模式管理子功能默认为MBB模式，接收到***在线事件，确认无线通信模块处于在线状态，保持默认的MBB模式；
协议栈基于通信状态指示消息的控制流程注网成功后，拨号连接管理(Connection Manager)子功能会接收到注网成功的消息；
拨号连接管理子功能接收到注网成功的消息，将无线通信模块作为MQTT客户端(MQTT Client)，利用第一SIM卡基于MQTT协议发起到云服务器(Cloud Server)的拨号连接；以及
拨号连接建立后，无线通信模块与云服务器建立无线通信连接。
请参见图3，图3为本公开一实施例所提供的终端设备在IoT模式的通信过程示意图，该过程为在IoT模式下的通信过程，以通信过程中涉及的子功能和具体的组件对具体的通信过程进行描述，可以包括：
无线通信模块上电启动后，通信状态指示消息处理(MBIM Message Handler)子功能定时器超时仍未接收到任何通信状态指示消息，将确认当前终端设备处于休眠/关机状态，所以发送***离线事件给设备模式管理(Device Mode Manager)子功能；
无线通信模块模块启动，设备模式管理默认为MBB模式，接收到***离线事件，判断无线通信模块处于***离线状态，将自动切换到IoT模式，包括提供业务的SIM由第一SIM卡切换为第二SIM卡，并激活第二SIM卡的预置文件；例如可以从USIM切换至内置eSIM卡，并激活eSIM卡内容的预置文件；
激活第二SIM卡的预置文件后，将使用该预置文件发起注网流程，设备模式管理子功能将给协议栈(Cellular Protocol Stack)发送注网请求消息；
协议栈注网成功后，拨号连接管理(Connection Manager)子功能会接收到注网成功的消息；
拨号连接管理子功能接收到注网成功的消息，将无线通信模块作为(MQTT Client)，利用第二SIM卡基于MQTT协议发起到云服务器(Cloud Server)的拨号连接；以及
