为了更清楚地说明本发明的技术方案，下面将对本发明的描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发明作进一步详细的说明。显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
参照图1，示出了本发明一实施例提供的一种终端设备与终端设备通信的方法的步骤流程图，该方法可以应用于第二终端设备。
其中，第二终端设备为基于远距离无线电广域网的终端设备，其具体可以为基于远距离无线电广域网中设备到设备模式的终端设备。
具体的，可以包括如下步骤：
步骤101，所述第二终端设备接收第一终端设备发送的一个或多个唤醒帧中任一个唤醒帧；其中，每个唤醒帧至少携带有第一接收端设备地址集合；
其中，第一终端设备为基于远距离无线电广域网的终端设备，其具体可以为基于远距离无线电广域网中设备到设备模式的终端设备，即第一终端设备和第二终端设备为采用远距离无线电广域网中设备到设备模式进行通信。
如图2a和图2b，唤醒帧可以包括前导码部分和数据部分，第一接收端设备地址集合可以包含于唤醒帧的数据部分，第一接收端设备地址集合可以包含一个或多个终端设 备的设备地址，该一个或多个终端设备的设备地址为第一终端设备需要对其发送消息的终端设备的设备地址，其可以由第一终端设备根据实际需求来进行设置。
在第一终端设备需要向一个或多个终端设备发送消息时，第一终端设备可以先发送唤醒帧，其可以发送一个唤醒帧，也可以发送多个唤醒帧，使得远距离无线电广域网中设备到设备模式下可以支持多个唤醒帧。
如图2a为第一终端设备发送一个唤醒帧的情况，在发送一个唤醒帧的情况下，其处理方式较为简单、唤醒率高，但存在前导码数据量很大的情况，导致接收唤醒帧的终端设备耗能较大。
如图2b为第一终端设备发送多个唤醒帧的情况，在发送多个唤醒帧的情况下，其前导码数据量较小，终端设备只要接收到任一个唤醒帧，进而可以进入休眠状态，降低能耗，但其处理较为复杂，唤醒率略低。
在接收到第一终端设备发送的唤醒帧后，接收到的唤醒帧可以为第一终端设备发送的唯一一个唤醒帧，也可以为第一终端设备发送的多个唤醒帧中的任一个唤醒帧。
步骤102，所述第二终端设备在检测到所述第一接收端设备地址集合中包含所述第二终端设备的设备地址的情况下，接收所述第一终端设备发送的一个或多个普通帧。
其中，普通帧可以包括前导码部分和数据部分，唤醒帧的前导码部分中前导码和普通帧的前导码部分中前导码可以不同，使得远距离无线电广域网中设备到设备模式下可以支持多个前导码。
在一示例中，普通帧的数据部分可以包含第二接收端设备地址集合，第二接收端设备地址集合可以包含一个或多个终端设备的设备地址，该一个或多个终端设备的设备地址为第一终端设备需要对其发送消息的终端设备的设备地址，第一终端设备需要对其发送消息的其可以由第一终端设备根据实际需求来进行设置。当然，普通帧的数据部分还包含具体内容部分，如具体内容部分可以包括参数设置命令。
在从唤醒帧的数据部分中读取第一接收端设备地址集合后，第二终端设备可以判断其自身的设备地址是否包含在第一接收端设备地址集合中，在第一接收端设备地址集合中仅存在一个设备地址的情况下，可以直接判断该设备地址是否与自身的设备地址相同。
如果自身的设备地址未包含在第一接收端设备地址集合中，表征第一终端设备不需要向第二终端设备发送消息，则在第一终端设备继续发送普通帧时，第二终端设备可以直接忽略，不进行接收。
如果自身的设备地址包含在第一接收端设备地址集合中，表征第一终端设备需要向第二终端设备发送消息，则在第一终端设备继续发送普通帧时，第二终端设备可以进一步从第一终端设备接收后续的普通帧。
具体的，如图2a和图2b，当通信包数据量较小时，第一终端设备可以发送一个普通帧，当通信包数据量较大时，也可以发送多个普通帧，使得远距离无线电广域网中设 备到设备模式下可以支持多个普通帧。
实际上，通过设置第一接收端设备地址集，第一终端设备在发送一个消息后，其他终端设备可以获知其是否为需要接收消息的终端设备，在其不为需要接收消息的终端设备的情况下则进行忽略，在其为需要接收消息的终端设备的情况下则可以进一步接收消息，进而可以实现一个消息发送多个终端设备，例如，终端设备A要向100个终端设备发送参数设置消息，原来需要按照终端设备逐个地发送100条消息，现在只需要发送1条消息，即可以让100个终端设备收到。
在本发明实施例中，第二终端设备通过接收第一终端设备发送的一个或多个唤醒帧中任一个唤醒帧，每个唤醒帧至少携带有第一接收端设备地址集合，在检测到第一接收端设备地址集合中包含第二终端设备的设备地址的情况下，接收第一终端设备发送的一个或多个普通帧，实现了发送端设备通过一条消息与多个接收端设备进行通信，支持多个接收端设备、多个唤醒帧、多个普通帧的情况，提升了通信效率，减少了资源消耗。
参照图3，示出了本发明一实施例提供的另一种终端设备与终端设备通信的方法的步骤流程图，该方法可以应用于第二终端设备。
具体的，可以包括如下步骤：
步骤301，第二终端设备接收第一终端设备发送的一个或多个唤醒帧中任一个唤醒帧；其中，每个唤醒帧至少携带有第一接收端设备地址集合和第一下一帧时间间隔信息。
其中，第一下一帧时间间隔信息可以包含于唤醒帧的数据部分，该第一下一帧时间间隔信息可以用于确定在该唤醒帧之后接收第一个普通帧的时间信息，即第一下一帧时间间隔信息可以为唤醒帧和普通帧之间的时间间隔信息，如第一下一帧时间间隔可以为第一终端设备发送唤醒帧的时间和第一终端设备发送第一个普通帧的时间间隔。
需要说明的是，在第一终端设备向第二终端设备发送多个唤醒帧的情况下，每个唤醒帧都携带有第一下一帧时间间隔信息，且每个唤醒帧携带的第一下一帧时间间隔信息不相同，如第一个唤醒帧写1.08秒、第二个唤醒帧写1.03秒，依次类推。在第一终端设备向第二终端设备发送一个唤醒帧的情况下，该唤醒帧可以携带第一下一帧时间间隔信息，也可以不携带第一下一帧时间间隔信息，而直接采用预先约定的下一帧时间间隔信息。
在第一终端设备需要向一个或多个终端设备发送消息时，第一终端设备可以先发送唤醒帧，其可以发送一个唤醒帧，也可以发送多个唤醒帧，使得远距离无线电广域网中设备到设备模式下可以支持多个唤醒帧。
在接收到第一终端设备发送的唤醒帧后，接收到的唤醒帧可以为第一终端设备发送的唯一一个唤醒帧，也可以为第一终端设备发送的多个唤醒帧中的任一个唤醒帧。
步骤302，第二终端设备在检测到第一接收端设备地址集合中包含第二终端设备的设备地址的情况下，按照接到的唤醒帧中携带的第一下一帧时间间隔信息，接收第一终 端设备发送的第一个普通帧。在从唤醒帧的数据部分中读取第一接收端设备地址集合后，第二终端设备可以判断其自身的设备地址是否包含在第一接收端设备地址集合中，在第一接收端设备地址集合中仅存在一个设备地址的情况下，可以直接判断该设备地址是否与自身的设备地址相同。
如果自身的设备地址未包含在第一接收端设备地址集合中，表征第一终端设备不需要向第二终端设备发送消息，则在第一终端设备继续发送普通帧时，第二终端设备可以直接忽略，不进行接收。
如果自身的设备地址包含在第一接收端设备地址集合中，表征第一终端设备需要向第二终端设备发送消息，第二终端设备可以进一步从唤醒帧的数据部分中获取第一下一帧时间间隔信息。
由于第一下一帧时间间隔信息中指示了发送第一个普通帧的时间间隔，则第二终端设备可以按照第一下一帧时间间隔信息来接收第一终端设备发送的第一个普通帧，且在第一下一帧时间间隔信息对应的间隔时间内，第二终端设备可以进行休眠等操作，节省能耗。
需要说明的是，在第一终端设备仅发送一个普通帧的情况下，这里所指的第一个普通帧即为该普通帧，则不存在后续的不同帧。在第一终端设备发送多个普通帧的情况下，则在第一个普通帧后还有其他的普通帧。
参照图4，示出了本发明一实施例提供的另一种终端设备与终端设备通信的方法的步骤流程图，该方法可以应用于第二终端设备。
具体的，可以包括如下步骤：
步骤401，第二终端设备接收第一终端设备发送的一个或多个唤醒帧中任一个唤醒帧；其中，每个唤醒帧至少携带有第一接收端设备地址集合和第一下一帧时间间隔信息。
步骤402，第二终端设备在检测到第一接收端设备地址集合中包含第二终端设备的设备地址的情况下，按照接到的唤醒帧中携带的第一下一帧时间间隔信息，接收第一终端设备发送的第一个普通帧。
步骤403，第二终端设备在接收到第一终端设备发送的第N个普通帧的情况下，按照第N个普通帧携带的第二下一帧时间间隔信息，接收第一终端设备发送的第N+1个普通帧；其中，在存在多个普通帧的情况下，第N个普通帧携带有第二下一帧时间间隔信息，N为大于或等于1的正整数。
对于存在多个普通帧的情况下，除了最后一个普通帧之外的其他普通帧(包括第一个普通帧)都可以携带有第二下一帧时间间隔信息，第二下一帧时间间隔信息可以包含于普通帧的数据部分，其可以用于确定接收下一个普通帧的时间。
具体的，第二下一帧时间间隔信息可以为相邻两个普通帧之间的时间间隔信息，其可以设置为与第一下一帧时间间隔信息相同，如第N个普通帧中携带的第二下一帧时间 间隔可以为第一终端设备发送第N个普通帧的时间和发送第N+1个普通帧的时间间隔。
第一终端设备可以第一终端设备在发送的第N个普通帧后，按照第N个普通帧携带的第二下一帧时间间隔信息，发送第N+1个普通帧，保证相邻两个普通帧之间存在第二下一帧时间间隔信息对应的时间间隔，
第二终端设备在接收到第一终端设备发送的第N个普通帧的情况下，可以按照第N个普通帧携带的第二下一帧时间间隔信息，接收第一终端设备发送的第N+1个普通帧，且在第二下一帧时间间隔信息对应的间隔时间内，第二终端设备可以进行休眠等操作，节省能耗。
需要说明的是，在第一终端设备向第二终端设备发送一个普通帧的情况下，该普通帧可以携带第二下一帧时间间隔信息，也可以不携带第二下一帧时间间隔信息，而直接采用预先约定的下一帧时间间隔信息。在第一终端设备向第二终端设备发送多个普通帧的情况下，除最后一个普通帧之外的其他普通帧可以携带第二下一帧时间间隔信息，也可以不携带第二下一帧时间间隔信息，而直接采用预先约定的下一帧时间间隔信息。

其中，第二终端设备为基于远距离无线电广域网的终端设备，其具体可以为基于远距离无线电广域网中设备到设备模式的终端设备，即第一终端设备和第二终端设备为采用远距离无线电广域网中设备到设备模式进行通信。
如图2a和图2b，唤醒帧可以包括前导码部分和数据部分，第一接收端设备地址集合可以包含于唤醒帧的数据部分，第一接收端设备地址集合可以包含一个或多个终端设备的设备地址，该一个或多个终端设备的设备地址为第一终端设备需要对其发送消息的终端设备的设备地址，其可以由第一终端设备根据实际需求来进行设置。
在第一终端设备需要向一个或多个终端设备发送消息时，第一终端设备可以先发送唤醒帧，其可以发送一个唤醒帧，也可以发送多个唤醒帧，使得远距离无线电广域网中设备到设备模式下可以支持多个唤醒帧。
如图2a为第一终端设备发送一个唤醒帧的情况，在发送一个唤醒帧的情况下，其处理方式较为简单、唤醒率高，但存在前导码数据量很大的情况，导致接收唤醒帧的终端设备耗能较大。

在本发明一实施例中，在存在多个普通帧的情况下，第N个普通帧携带有第二下一帧时间间隔信息，N为大于或等于1的正整数，步骤502还可以包括：
第一终端设备在已发送第N个普通帧的情况下，按照第N个普通帧携带的第二下一帧时间间隔信息，发送第N+1个普通帧，以使第二终端设备在接收到第一终端设备发送的第N个普通帧的情况下，按照第N个普通帧携带的第二下一帧时间间隔信息，接收第一终端设备发送的第N+1个普通帧。
对于存在多个普通帧的情况下，除了最后一个普通帧之外的其他普通帧(包括第一个普通帧)都可以携带有第二下一帧时间间隔信息，第二下一帧时间间隔信息可以包含于普通帧的数据部分，其可以用于确定接收下一个普通帧的时间。
具体的，第二下一帧时间间隔信息可以为相邻两个普通帧之间的时间间隔信息，其可以设置为与第一下一帧时间间隔信息相同，如第N个普通帧中携带的第二下一帧时间间隔可以为第一终端设备发送第N个普通帧的时间和发送第N+1个普通帧的时间间隔。
第一终端设备可以第一终端设备在发送的第N个普通帧后，按照第N个普通帧携带的第二下一帧时间间隔信息，发送第N+1个普通帧，保证相邻两个普通帧之间存在第二下一帧时间间隔信息对应的时间间隔，
第二终端设备在接收到第一终端设备发送的第N个普通帧的情况下，可以按照第N个普通帧携带的第二下一帧时间间隔信息，接收第一终端设备发送的第N+1个普通帧，且在第二下一帧时间间隔信息对应的间隔时间内，第二终端设备可以进行休眠等操作，节省能耗。
需要说明的是，在第一终端设备向第二终端设备发送一个普通帧的情况下，该普通帧可以携带第二下一帧时间间隔信息，也可以不携带第二下一帧时间间隔信息，而直接采用预先约定的下一帧时间间隔信息。在第一终端设备向第二终端设备发送多个普通帧的情况下，除最后一个普通帧之外的其他普通帧可以携带第二下一帧时间间隔信息，也可以不携带第二下一帧时间间隔信息，而直接采用预先约定的下一帧时间间隔信息。
在本发明实施例中，第一终端设备通过发送一个或多个唤醒帧，以使一个或多个第二终端设备接收到一个或多个唤醒帧中任一个唤醒帧，每个唤醒帧至少携带有第一接收端设备地址集合，然后发送一个或多个普通帧，第二终端设备可以在检测到第一接收端设备地址集合中包含第二终端设备的设备地址的情况下，接收第一终端设备发送的一个或多个普通帧，实现了发送端设备通过一条消息与多个接收端设备进行通信，支持多个接收端设备、多个唤醒帧、多个普通帧的情况，提升了通信效率，减少了资源消耗。
