Description

消息收发方法及设备
交叉引用
本申请要求在2022年07月04日提交的申请号为202210780063.8的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请属于信息处理技术领域，具体涉及一种消息收发方法及设备。
背景技术
在消息收发过程中，接收端的无源设备要求有足够的接收信号功率，当信号的接收电平较小时，需要较长的时间进行储能，储能不足将导致无法接收信号或者信号接收效果较差。以无源设备为标签机为例，假设读取器需要从标签机内获取数据，标签机的电路设计要求有足够的接收信号功率，在标签机接收读取器发送的消息时，通过整流器和稳压器后输出给数字信号处理单元，该阶段需要一直有稳压器的输出电流供给数字信号处理单元，这对于标签机的供电有一定的要求。当信号的接收电平较小时，标签机通过一定时间的能量累计可以达到一定的输出电压和输出电流，以驱动数字信号单元进行信号的开关调制。但是，如果标签机在发送消息阶段时间持续较长，则会对前期能量的累计要求比较高，从而影响信号收发效果。
发明内容
本申请实施例提供一种消息收发方法及设备，能够解决无源设备在储能不足时消息收发效果较差的问题。
第一方面，提供了一种消息收发方法，应用于第一设备，该方法包括：接收第二设备发送的第一消息；所述第一消息包括对目标数据的获取请求；向所述第二设备发送用于响应所述第一消息的第二消息；向所述第二设备发送第四消息；所述第四消息包括所述目标数据。
第二方面，提供了一种消息收发设备，该设备包括：第一接收模块，用于接收第二设 备发送的第一消息；所述第一消息包括对目标数据的获取请求；第一发送模块，用于向所述第二设备发送用于响应所述第一消息的第二消息；第二发送模块，用于向所述第二设备发送第四消息；所述第四消息包括所述目标数据。
第三方面，提供了一种消息收发方法，应用于第二设备，该方法包括：向第一设备发送第一消息；所述第一消息包括对目标数据的获取请求；接收来自所述第一设备的、用于响应所述第一消息的第二消息；接收来自所述第二设备的第四消息；所述第四消息包括所述目标数据。
第四方面，提供了一种消息收发设备，该设备包括：第三发送模块，用于向第一设备发送第一消息；所述第一消息包括对目标数据的获取请求；第三接收模块，用于接收来自所述第一设备的、用于响应所述第一消息的第二消息；第四接收模块，用于接收来自所述第二设备的第四消息；所述第四消息包括所述目标数据。
第五方面，提供了一种终端，该终端包括处理器和存储器，所述存储器存储可在所述处理器上运行的程序或指令，所述程序或指令被所述处理器执行时实现如第一方面所述的消息收发方法的步骤，或者，所述程序或指令被所述处理器执行时实现如第三方面所述的消息收发方法的步骤。
第六方面，提供了一种网络侧设备，该网络侧设备包括处理器和存储器，所述存储器存储可在所述处理器上运行的程序或指令，所述程序或指令被所述处理器执行时实现如第一方面所述的消息收发方法的步骤，或者，所述程序或指令被所述处理器执行时实现如第三方面所述的消息收发方法的步骤。
第七方面，提供了一种消息收发系统，包括：终端及网络侧设备，所述终端可用于执行如第一方面所述的消息收发方法的步骤，所述网络侧设备可用于执行如第三方面所述的消息收发方法的步骤。
第八方面，提供了一种消息收发系统，包括：终端及网络侧设备，所述终端可用于执行如第三方面所述的消息收发方法的步骤，所述网络侧设备可用于执行如第一方面所述的消息收发方法的步骤。
第九方面，提供了一种可读存储介质，所述可读存储介质上存储程序或指令，所述程序或指令被处理器执行时实现如第一方面所述的方法的步骤，或者实现如第三方面所述的方法的步骤。
第十方面，提供了一种芯片，所述芯片包括处理器和通信接口，所述通信接口和所述处理器耦合，所述处理器用于运行程序或指令，实现如第一方面所述的方法，或者实现如第三方面所述的方法。
第十一方面，提供了一种计算机程序/程序产品，所述计算机程序/程序产品被存储在存储介质中，所述计算机程序/程序产品被至少一个处理器执行以实现如第一方面所述的方法，或者实现如第三方面所述的方法。
在本申请实施例中，第一设备接收第二设备发送的第一消息，该第一消息包括对目标数据的获取请求，向第二设备发送用于响应第一消息的第二消息。之后，向第二设备发送第四消息，第四消息包括目标数据。可见，在第二设备需要获取第一设备中的目标数据并发出第一消息后，第一设备并非是立即将目标数据发送至第二设备，而是先产生第一消息的响应消息(即第二消息)，将该响应信息发送给第二设备，然后才会将目标数据发送给第二设备。由于第二消息属于中间响应消息，即不携带真实的目标数据，因此设备双方通过第二消息的交互，能够避免第一设备将目标数据发送至其他设备(非第二设备)的情况，从而确保了消息收发的准确性。并且，相较于现有技术的消息收发流程，比如第一设备接收到来自第二设备的第一消息后、直接将目标数据发送给第二设备而言，本申请提供的消息收发流程更加完善。此外，在设备盘点模式(如第二设备从第一设备中获取数据进行盘点)下，设备双方通过中间响应消息的交互，不仅能确保数据传输的准确性，还能使第一设备(如无源设备)有更多的时间进行储能，从而在储能充足的情况下收发消息，确保消息收发效果以及目标数据传输的成功率。

下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的消息收发方法进行详细地说明。
图2是根据本申请一实施例的一种消息收发方法的示意性流程图，本实施例中，消息收发方法应用于第一设备，第一设备可以是如图1所示的终端11或者网络侧设备12。如图2所述，该方法包括：
S202，接收第二设备发送的第一消息；第一消息包括对目标数据的获取请求。
其中，目标数据可存储于第一设备中，也可存储于与第一设备相关联的其他设备或者存储器中。
S204，向第二设备发送用于响应第一消息的第二消息。
S206，向第二设备发送第四消息；第四消息包括目标数据。
其中，若目标数据存储于第一设备中，则第一设备从本地获取目标数据携带于第四消息中发送给第二设备。若目标数据存储于与第一设备相关联的其他设备或者存储器中，则第一设备从其他设备或者存储器中获取目标数据，然后再将目标数据携带于第四消息中发送至第二设备。
在本申请实施例中，第一设备接收第二设备发送的第一消息，该第一消息包括对目标数据的获取请求，向第二设备发送用于响应第一消息的第二消息。之后，向第二设备发送第四消息，第四消息包括目标数据。可见，在第二设备需要获取第一设备中的目标数据并发出第一消息后，第一设备并非是立即将目标数据发送至第二设备，而是先产生第一消息的响应消息(即第二消息)，将该响应信息发送给第二设备，并在第二设备再次响应之后，第一设备才会将目标数据发送给第二设备。由于第二消息属于中间响应消息，即不携带真实的目标数据，因此设备双方通过第二消息的交互，能够避免第一设备将目标数据发送至其他设备(非第二设备)的情况，从而确保了消息收发的准确性。并且，相较于现有技术 的消息收发流程，比如第一设备接收到来自第二设备的第一消息后、直接将目标数据发送给第二设备而言，本申请提供的消息收发流程更加完善。此外，在设备盘点模式(如第二设备从第一设备中获取数据进行盘点)下，设备双方通过中间响应消息的交互，不仅能确保数据传输的准确性，还能使第一设备(如无源设备)有更多的时间进行储能，从而在储能充足的情况下收发消息，确保消息收发效果以及目标数据传输的成功率。
在一个实施例中，第一设备向第二设备发送第四消息之前，可接收来自第二设备的、用于响应第二消息的第三消息，并在成功接收到第三消息之后，再向第二设备发送第四消息。由于第三消息属于中间响应消息，即不携带真实的目标数据，因此设备双方通过第三消息的交互，能够使消息收发效果更佳，这在多个设备之间同时交互的场景中体现更加突出。例如，若多个第二设备同时向第一设备发送第一消息，以获取目标数据。如果第一设备向每个第二设备发送第二消息之后，接着向每个第二设备发送第四消息，就会导致第一设备同时向多个第二设备发送数据的情况，从而造成数据传输拥堵现象，影响数据传输的成功率。而如果第一设备先等待第二设备发送第三消息，并在成功接收到第三消息之后、再向发送该第三消息的第二设备发送第四消息，就能够避免同时向多个第二设备发送数据的情况，从而避免数据传输拥堵现象，提升数据传输的成功率。
图3是根据本申请一实施例的一种消息收发方法的示意性时序图。如图3所示，图中以竖线排列的序列表示时间轴线，时间轴线上从左到右依次表示时间先后顺序。若无特别说明，本申请其他实施例所对应的附图中，均以竖线排列的序列表示时间轴线。第二设备首先向第一设备发送第一消息，第一设备在接收到第一消息的时间t之后，向第一设备发送第二消息，其中，时间t表示第一设备对第一消息的处理时间，包括解析第一消息。然后，第一设备接收来自第二设备的第三消息，T1表示第一设备发送第二消息和接收第三消息之间的时间间隔，T1可大于或等于0。然后，第一设备向第二设备发送包括目标数据的第四消息，T2表示第一设备接收第三消息和发送第四消息之间的时间间隔，T2可大于或等于0。
本实施例中，第二消息可以由第一设备生成，比如生成一个16比特的随机字符，作为第二消息发送给第二设备。由于第三消息是为了响应第二消息，因此第三消息至少包括由第一设备发送的16比特的随机字符，例如，第三消息为ACK(Acknowledgement，确认字符)指令的形式，则第二设备通过ACK指令将16比特的随机字符反馈给第一设备，以触发第一设备向第二设备发送目标数据。
以第一设备为标签机、第二设备为读取器为例，假设在盘点模式下，读取器需从标签机中查询目标数据，则读取器首先向标签机发送查询指令(Query)，该查询指令即为第一 消息。然后，标签机接收到查询指令后，生成一个16比特的随机字符(即RN16)，将RN16发送给读取器。然后，读取器通过ACK指令的形式将RN16反馈给标签机，以触发标签机向读取器发送目标数据。
在一个实施例中，第一设备接收来自第二设备的第三消息时，可以在发送第二消息之后立即接收第三消息，此时图3中所示的T1为0。也可在发送第二消息之后等待一段时间后接收第三消息，即延时接收第三消息，此时图3中所示的T1大于0。可选地，在第一时刻接收第三消息，其中，第一时刻基于以下至少一项确定：第一时间信息、第一设备的设备状态信息、第三消息的信息长度、第一设备能够接收的消息的长度。
其中，第一时间信息可包括以下至少一项：第一时刻、第一设备发送第二消息与接收第三消息之间的第一时间间隔。第一时刻为第一设备发送第二消息之后的某个时刻。若第一时间信息包括第一时刻，即第一设备能够直接获知在哪个时刻接收第三消息。比如，第一设备在10:00:00点(即10点整)发送了第二消息，第一时刻为10:00:10点(即10点0分10秒)，则第一设备在10:00:10点接收第三消息。若第一时间信息包括第一时间间隔，则第一设备能够获知发送第二消息之后需等待的时间间隔。比如，第一设备在10:00:00点(即10点整)发送了第二消息，第一时间间隔为1秒，则第一设备在发送第二消息之后，等待1秒后接收第三消息。
第一设备的设备状态信息可包括以下至少一项：不延时收发消息的第一状态信息、延时收发消息的第二状态信息、第一设备的储能信息。其中，储能信息用于表征第一设备不延时收发消息、或者延时收发消息。比如，储能信息包括具体的储备能量，或者储备能量是否需要延时收发消息。
第一时间信息、第一设备的设备状态信息、第三消息的信息长度以及第一设备能够接收的消息的长度，这几种信息的携带方式有多种，以下详细说明。
在一个实施例中，第一消息或者第二消息包括第一时间信息。在第一消息包括第一时间信息的情况下，第一时间信息由第二设备确定并发送给第一设备。第一设备接收到第一消息后，可根据第一消息携带的第一时间信息，确定第一时刻，进而在第一时刻接收来自第二设备的第三消息。
其中，第二设备在确定第一时间信息时，可以根据第一设备和第二设备预先约定或配置好的信息来确定，比如，第一设备和第二设备预先约定或配置了第一时间信息。或者，第二设备可根据第一设备的设备状态信息来确定第一时间信息。基于此，第一设备可预先向第二设备发送设备状态信息，以使第二设备在发送第一消息之前，即可根据第一设备发送的设备状态信息确定第一时间信息，进而将第一时间信息携带在第一消息中一并发送给 第一设备。
在第二消息包括第一时间信息的情况下，第一时间信息由第一设备确定并发送给第二设备。第二设备接收到第二消息后，可根据第二消息携带的第一时间信息，确定第一时刻，进而在第一时刻向第一设备发送第三消息。
其中，第一设备在确定第一时间信息时，可根据第一设备和第二设备预先约定或配置好的信息来确定，比如，第一设备和第二设备预先约定或配置了第一时间信息。或者，第一设备可根据自身的设备状态信息来确定第一时间信息。第一设备在接收第三消息之前(比如在接收到第一消息之后、或者发送第二消息之后)，先根据自身的设备状态信息确定第一时间信息，然后将第一时间信息携带在第二消息中一并发送给第二设备，以使第二设备根据第一时间信息确定第一时刻，并在第一时刻向第一设备发送第三消息。
在一个实施例中，第一消息包括第三消息的信息长度。在第一消息包括第三消息的信息长度的情况下，第三消息的信息长度由第二设备确定并发送给第一设备。第一设备接收到第一消息后，可根据第一消息携带的第三消息的信息长度，确定第一时刻，进而在第一时刻接收来自第二设备的第三消息。
可选地，第一设备和第二设备可以预先约定或配置好消息收发过程中各个消息的信息长度，包括第三消息的信息长度。这样，第二设备可根据预先约定或配置好的信息，确定第三消息的信息长度，进而将第三消息的信息长度携带在第一消息中一并发送给第一设备。
在一个实施例中，第二消息包括第一设备能够接收的消息的信息长度，第一设备能够接收的消息的信息长度由第一设备确定并发送给第二设备。可选地，第一设备可根据自身的设备状态信息确定能够接收消息的信息长度，比如，确定当前的储能信息能够收发的消息的信息长度是多少。第二设备接收到第二消息后，可根据第二消息携带的第一设备能够接收的消息的信息长度，确定第一时刻，进而在第一时刻向第一设备发送第三消息，此时，第二设备发送的第三消息的长度应和第一设备能够接收的消息的信息长度相匹配，比如，第三消息的长度小于或等于第一设备能够接收的消息的信息长度。
可选地，由于第二消息是由第一设备生成的随机字符，第三消息是针对第二消息的响应消息，因此，第一设备可以根据所生成的第二消息来确定第三消息的信息长度，进而将第三消息的信息长度确定为第一设备能够接收的消息的信息长度。比如，第一设备生成的第二消息的信息长度为16比特，则第三消息的信息长度可以是16比特，或者，在第三消息中需要携带其他信息的情况下，第三消息的信息长度可以大于16比特，比如32比特。
可选地，第一设备也可根据和第二设备预先约定或配置好的信息，确定第一设备能够 接收的消息的信息长度，进而将第一设备能够接收的消息的信息长度携带在第二消息中一并发送给第二设备。
在一个实施例中，第二消息包括设备状态信息，也即，第一设备的设备状态信息由第一设备通过第二消息发送给第二设备。设备状态信息包括以下其中一项：不延时收发消息的第一状态信息、延时收发消息的第二状态信息、第一设备的储能信息，其中，储能信息用于表征第一设备不延时收发消息、或者延时收发消息。可选地，第一设备可根据自身的储能信息来确定设备状态信息是第一状态信息或者第二状态信息。第二设备接收到第二消息后，根据第二消息携带的设备状态信息确定第一时刻，进而在第一时刻向第一设备发送第三消息。
在一个实施例中，执行S206时，即发送第四消息时，可以在接收第三消息之后立即发送第四消息，此时图3中所示的T2为0。也可在接收第三消息之后等待一段时间后发送第四消息，即延时发送第四消息，此时图3中所示的T2大于0。可选地，第一设备在第二时刻向第二设备发送第四消息，其中，第二时刻基于以下至少一项确定：第二时间信息、第一设备的设备状态信息、第四消息的信息长度、第二设备能够接收的消息的长度。
其中，第二时间信息可包括以下至少一项：第二时刻、第一设备发送第二消息与发送第四消息之间的第二时间间隔、第一设备接收第三消息与发送第四消息之间的第三时间间隔、接收第一消息与发送第四消息之间的第四时间间隔。第二时刻为第一设备接收第三消息之后的某个时刻。若第二时间信息包括第二时刻，即第二设备能够直接获知在哪个时刻发送第四消息。比如，第一设备在10:00:00点(即10点整)接收了第三消息，第二时刻为10:00:10点(即10点0分10秒)，则第一设备在10:00:10点发送第四消息。若第二时间信息包括第二时间间隔，则第一设备能够获知发送第二消息之后需等待的时间间隔。比如，第一设备在10:00:00点(即10点整)发送了第二消息，第二时间间隔为1秒，则第一设备在发送第二消息之后，等待1秒后发送第四消息。需要说明的是，由于第一设备在发送第四消息之后需接收第三消息，因此第二时间间隔应大于发送第二消息和接收第三消息之间的时间间隔。若第二时间信息包括第三时间间隔，则第一设备能够获知接收第三消息之后需等待的时间间隔。比如，第一设备在10:00:00点(即10点整)接收了第三消息，第三时间间隔为1秒，则第一设备在接收第三消息之后，等待1秒后发送第四消息。
第一设备的设备状态信息可包括以下至少一项：不延时收发消息的第一状态信息、延时收发消息的第二状态信息、第一设备的储能信息。其中，储能信息用于表征第一设备不延时收发消息、或者延时收发消息。
第二时间信息、第一设备的设备状态信息、第四消息的信息长度以及第二设备能够接 收的消息的长度，这几种信息的携带方式有多种，以下详细说明。
在一个实施例中，第二消息或者第三消息包括第二时间信息。
在第二消息包括第二时间信息的情况下，第二时间信息由第一设备确定并发送给第二设备。第二设备接收到第二消息后，可根据第二消息携带的第二时间信息，确定第二时刻，进而在第二时刻接收第一设备发送的第四消息。
其中，第一设备在确定第二时间信息时，可以根据第一设备和第二设备预先约定或配置好的信息来确定，比如，第一设备和第二设备预先约定或配置了第二时间信息。或者，第一设备可根据自身的设备状态信息来确定第二时间信息。第一设备在发送第四消息之前，先根据自身的设备状态信息确定第二时间信息，然后将第二时间信息携带在第二消息中一并发送给第二设备。第一设备在第二时刻向第二设备发送第四消息，同时，第二设备根据第二消息中携带的第二时间信息确定第二时刻，并在第二时刻接收第一设备发送的第四消息。
在第三消息包括第二时间信息的情况下，第二时间信息由第二设备确定并发送给第一设备。第一设备接收到第三消息后，可根据第三消息携带的第二时间信息，确定第二时刻，进而在第二时刻向第二设备发送第四消息。
其中，第二设备在确定第二时间信息时，可根据第一设备和第二设备预先约定或配置好的信息来确定，比如，第一设备和第二设备预先约定或配置了第二时间信息。或者，第二设备可根据第一设备的设备状态信息来确定第二时间信息。基于此，第一设备可预先向第二设备发送设备状态信息，以使第二设备在第一设备发送第四消息之前，即可根据第一设备发送的设备状态信息确定第二时间信息，进而将第二时间信息携带在第三消息中一并发送给第一设备。
在一个实施例中，第二消息包括第四消息的信息长度。在第二消息包括第四消息的信息长度的情况下，第四消息的信息长度由第一设备确定并发送给第二设备。第二设备接收到第二消息后，可根据第二消息携带的第四消息的信息长度，确定第二时刻，进而在第二时刻接收第一设备发送的第四消息。
其中，第一设备和第二设备可以预先约定或配置好消息收发过程中各个消息的信息长度，包括第四消息的信息长度。这样，第一设备可根据预先约定或配置好的信息，确定第四消息的信息长度，进而将第四消息的信息长度携带在第二消息中一并发送给第二设备。
或者，由于目标数据存储于第一设备中，因此，第一设备可以根据目标数据来确定第四消息的信息长度。比如，目标数据的数据长度为32比特，则第四消息的信息长度可以是32比特，即目标数据的数据长度，或者，在第四消息中需要携带其他信息的情况下， 第四消息的信息长度可以大于32比特，比如48比特。
在一个实施例中，第三消息包括第二设备能够接收的消息的信息长度。第二设备能够接收的消息的信息长度由第二设备确定并发送给第一设备。第一设备接收到第三消息后，可根据第三消息携带的第二设备能够接收的消息的信息长度确定第二时刻，进而在第二时刻向第二设备发送第四消息。
可选地，第二设备可根据和第一设备预先约定或配置好的信息，确定第二设备能够接收的消息的信息长度，进而将第二设备能够接收的消息的信息长度携带在第三消息中一并发送给第一设备。可选地，第二设备可根据待获取的目标数据，预估第二设备能够接收的消息的信息长度。
在一个实施例中，第二消息包括设备状态信息，也即，第一设备的设备状态信息由第一设备通过第二消息发送给第二设备。设备状态信息包括以下其中一项：不延时收发消息的第一状态信息、延时收发消息的第二状态信息、第一设备的储能信息，其中，储能信息用于表征第一设备不延时收发消息、或者延时收发消息。可选地，第一设备可根据自身的储能信息来确定设备状态信息是第一状态信息或者第二状态信息。第二设备接收到第二消息后，根据第二消息携带的设备状态信息确定第二时刻，进而在第二时刻接收第一设备发送的第四消息。
由上述实施例可看出，在第二设备需要获取第一设备中的目标数据并发出第一消息后，第一设备并非是立即将目标数据发送至第二设备，而是能够基于时间信息(包括第一时间信息和/或第二时间信息)、第一设备的设备状态信息和/或待收发消息的信息长度来确定收发消息的时刻，包括接收第三消息的第一时刻、以及发送第四消息的第二时刻，因此，第一设备在消息收发过程中能够有更多的时间来累积能量，从而在第一设备能量充足(如具有足够的收发信号功率)的情况下进行消息收发，避免因设备能量不足而影响消息收发效果或者无法收发消息的情况。因此，第一设备在消息收发过程中能够有更多的时间来累积能量，从而在第一设备能量充足(如具有足够的收发信号功率)的情况下进行消息收发，避免因设备能量不足而影响消息收发效果或者无法收发消息的情况。
在一个实施例中，第一设备接收来自第二设备的第三消息之前，可确定自身的储能信息与第一时刻和/或第二时刻是否匹配。若不匹配，则向第二设备发送供能时间因子，该供能时间因子用于第二设备调整第一时刻和/或第二时刻。其中，第一设备的储能信息与第一时刻和/或第二时刻匹配，说明第一设备的储能信息足以按照第一时刻和/或第二时刻收发消息，此时不需要向第二设备发送供能时间因子。第一设备的储能信息与第一时刻和/或第二时刻不匹配，说明第一设备的储能信息不足以按照第一时刻和/或第二时刻收发消 息，此时需要增大第一时刻和/或第二时刻，从而使第一设备有更多的时间储备能量，确保第一设备的储能信息足以按照第一时刻和/或第二时刻收发消息。
储能信息可包括具体的储备能量和/或储备能量是否满足当前的调度时间需求。若储能信息包括储备能量，则第一设备可根据储备能量的值，确定出当前的储备能量是否满足调度时间需求。若储备能量满足调度时间需求，则说明第一设备的储能信息与第一时刻和/或第二时刻匹配；若储备能量不满足调度时间需求，则说明第一设备的储能信息与第一时刻和/或第二时刻不匹配。
可选地，第二消息包括供能时间因子，即，供能时间因子可携带于第二消息中发送至第二设备，第二设备根据供能时间因子调整第一时刻和/或第二时刻。
第一设备可根据第一设备的设备状态信息确定供能时间因子。设备状态信息可包括以下至少一项：不延时收发消息的第一状态信息、延时收发消息的第二状态信息、第一设备的储能信息。可选地，若设备状态信息为第一状态信息，则说明第一设备的储备能量较多，可确定第一设备的储能信息与第一时刻和/或第二时刻匹配。若设备状态信息为第二状态信息，则说明第一设备的储备能量较少，此时可进一步根据储备能量的值确定储能信息与第一时刻和/或第二时刻匹配。
本实施例中，第一设备可根据自身的设备状态信息确定供能时间因子，由于该供能时间因子可作用于第一时刻和/或第二时刻，因此使得消息收发的延时时间是动态可调整的，从而能够灵活地根据第一设备的设备状态信息动态调整第一设备和第二设备之间收发消息的时间，避免因设备能量不足而影响消息收发效果或者无法收发消息的情况。
图4是根据本申请另一实施例的一种消息收发方法的示意性流程图，本实施例中，消息收发方法应用于第二设备，第二设备可以是如图1所示的终端11或者网络侧设备12。如图4所述，该方法包括：
S402，向第一设备发送第一消息；第一消息包括对获取请求。
其中，目标数据可存储于第一设备中，也可存储于与第一设备相关联的其他设备或者存储器中。
S404，接收来自第一设备的、用于响应第一消息的第二消息。
S408，接收来自第一设备的第四消息；第四消息包括目标数据。
本实施例中，第二消息可以由第一设备生成，比如生成一个16比特的随机字符，作为第二消息发送给第二设备。由于第三消息是为了响应第二消息，因此第三消息至少包括由第一设备发送的16比特的随机字符，例如，第三消息为ACK(Acknowledgement，确认字符)指令的形式，则第二设备通过ACK指令将16比特的随机字符反馈给第一设备， 以触发第一设备向第二设备发送目标数据。第一设备和第二设备之间的消息收发机制，与图3所示实施例相同，此处不再赘述。
本申请实施例中，第二设备向第一设备发送第一消息，该第一消息包括对目标数据的获取请求，接收第一设备发送的用于响应第一消息的第二消息。之后，接收来自第一设备的第四消息，第四消息包括目标数据。可见，在第二设备需要获取第一设备中的目标数据并发出第一消息后，第一设备并非是立即将目标数据发送至第二设备，而是先产生第一消息的响应消息(即第二消息)，将该响应信息发送给第二设备，并在第二设备再次响应之后，第一设备才会将目标数据发送给第二设备。由于第二消息属于中间响应消息，即不携带真实的目标数据，因此设备双方通过第二消息的交互，能够避免第一设备将目标数据发送至其他设备(非第二设备)的情况，从而确保了消息收发的准确性。并且，相较于现有技术的消息收发流程，比如第一设备接收到来自第二设备的第一消息后、直接将目标数据发送给第二设备而言，本申请提供的消息收发流程更加完善。此外，在设备盘点模式(如第二设备从第一设备中获取数据进行盘点)下，设备双方通过中间响应消息的交互，不仅能确保数据传输的准确性，还能使第一设备(如无源设备)有更多的时间进行储能，从而在储能充足的情况下收发消息，确保消息收发效果以及目标数据传输的成功率。
在一个实施例中，第二设备接收来自第一设备的第四消息之前，可先向第一设备发送用于响应第二消息的第三消息，然后再接收来自第一设备的第四消息。由于第三消息属于中间响应消息，即不携带真实的目标数据，因此设备双方通过第三消息的交互，能够使消息收发效果更佳，这在多个设备之间同时交互的场景中体现更加突出。例如，若多个第二设备同时向第一设备发送第一消息，以获取目标数据。如果第一设备向每个第二设备发送第二消息之后，接着向每个第二设备发送第四消息，就会导致第一设备同时向多个第二设备发送数据的情况，从而造成数据传输拥堵现象，影响数据传输的成功率。而如果第一设备先等待第二设备发送第三消息，并在成功接收到第三消息之后、再向发送该第三消息的第二设备发送第四消息，就能够避免同时向多个第二设备发送数据的情况，从而避免数据传输拥堵现象，提升数据传输的成功率。
在一个实施例中，第二设备向第一设备发送第三消息时，可以在接收到第二消息之后立即发送第三消息，此时图3中所示的T1为0。也可在接收到第二消息之后等待一段时间后发送第三消息，即延时发送第三消息，此时图3中所示的T1大于0。可选地，在第一时刻发送第三消息，其中，第一时刻基于以下至少一项确定：第一时间信息、第一设备的设备状态信息、第三消息的信息长度、所述第一设备能够接收的消息的长度。
其中，第一时间信息可包括以下至少一项：第一时刻、第一设备发送第二消息与接收 第三消息之间的第一时间间隔。第一时刻为第一设备发送第二消息之后的某个时刻。
第一设备的设备状态信息可包括以下至少一项：不延时收发消息的第一状态信息、延时收发消息的第二状态信息、第一设备的储能信息。其中，储能信息用于表征第一设备不延时收发消息、或者延时收发消息。比如，储能信息包括具体的储备能量，或者储备能量是否需要延时收发消息。
第一时间信息、第一设备的设备状态信息、第三消息的信息长度以及第一设备能够接收的消息的长度，这几种信息的携带方式和上述实施例中相同，此处不再赘述。
在一个实施例中，执行S406时，即接收第四消息时，可以在发送第三消息之后立即接收第四消息，此时图3中所示的T2为0。也可在发送第三消息之后等待一段时间后接收第四消息，即延时接收第四消息，此时图3中所示的T2大于0。可选地，第二设备在第二时刻接收第四消息，其中，第二时刻基于以下至少一项确定：第二时间信息、第一设备的设备状态信息、第四消息的信息长度。
其中，第二时间信息可包括以下至少一项：第二时刻、第一设备发送第二消息与发送第四消息之间的第二时间间隔、第一设备接收第三消息与发送第四消息之间的第三时间间隔、第一设备接收第一消息与发送第四消息之间的第四时间间隔。第二时刻为第一设备接收第三消息之后的某个时刻。
第一设备的设备状态信息可包括以下至少一项：不延时收发消息的第一状态信息、延时收发消息的第二状态信息、第一设备的储能信息。其中，储能信息用于表征第一设备不延时收发消息、或者延时收发消息。
在一个实施例中，若设备状态信息包括第一状态信息，这说明第一设备在后续时刻已准备好收发消息。
若设备状态信息包括第二状态信息，这说明第一设备在后续时刻尚未准备好收发消息。因此，第二设备向第一设备发送用于响应第二消息的第三消息之后，若在预设时长内未接收到第一设备对第三消息的响应消息，则可按照预设时间间隔再次向第一设备发送第三消息，直至第三消息满足停止发送条件。其中，停止发送条件包括：第一设备对第三消息的接收到响应消息；和/或，第三消息的发送次数达到预设次数。
例如，当第一设备的设备状态信息为延时收发消息的第二状态信息时，说明第一设备需要延时收发后续消息，比如延时接收ACK。此时，第二设备可以多次尝试发送ACK，若在预设时长(比如10毫秒)内接收到第一设备对ACK的响应消息，则停止发送ACK。若在预设时长(比如10毫秒)内未接收到第一设备对ACK的响应消息，则在预设时间间隔后(比如20毫秒)后再次发送ACK，直至接收到第一设备对ACK的响应消息，或者 达到预设的发送次数。
第二时间信息、第一设备的设备状态信息、第四消息的信息长度以及第二设备能够接收的消息的长度，这几种信息的携带方式和上述实施例中相同，此处不再赘述。
由上述实施例可看出，在第二设备获取第一设备中的目标数据并发出第一消息后，第一设备并非是立即将目标数据发送至第二设备，而是能够基于时间信息(包括第一时间信息和/或第二时间信息)、第一设备的设备状态信息和/或待收发消息的信息长度来确定收发消息的时刻，包括发送第三消息的第一时刻、以及接收第四消息的第二时刻，因此，第一设备在消息收发过程中能够有更多的时间来累积能量，从而在第一设备能量充足(如具有足够的收发信号功率)的情况下进行消息收发，避免因设备能量不足而影响消息收发效果或者无法收发消息的情况。因此，第一设备在消息收发过程中能够有更多的时间来累积能量，从而在第一设备能量充足(如具有足够的收发信号功率)的情况下进行消息收发，避免因设备能量不足而影响消息收发效果或者无法收发消息的情况。
在一个实施例中，第二设备接收第一设备发送的供能时间因子，根据供能时间因子调整第一时刻和/或第二时刻。
可选地，第二消息包括供能时间因子，即，供能时间因子可携带于第二消息中由第一设备发送至第二设备，第二设备根据供能时间因子调整第一时刻和/或第二时刻。
下面以第一设备为标签机、第二设备为读取器为例，示例性地说明本申请提供的消息收发方法。
在一个实施例中，如图5所示，读取器需从标签机中查询目标数据，则读取器首先向标签机发送查询指令(Query)，该查询指令即为第一消息。然后，标签机接收到查询指令后，生成一个16比特的随机字符(即RN16)，将RN16发送给读取器。然后，读取器通过ACK指令的形式将RN16反馈给标签机，以触发标签机向读取器发送目标数据。
在实际应用中，标签机的电路设计要求有足够的接收信号功率，在标签机接收读取器发送的消息时，通过整流器和稳压器后输出给数字信号处理单元，该阶段需要一直有稳压器的输出电流供给数字信号处理单元，这对于标签机的供电有一定的要求。当信号的接收电平较小时，标签机通过一定时间的能量累计也可以达到一定的输出电压和输出电流，以驱动数字信号单元进行信号的开关调制。但是，如果标签机在发送消息阶段时间持续较长，则会对前期能量的累计要求比较高，从而影响信号接收效果。因此，需要有一定的延时收发消息机制来确保消息收发效果。
可选地，标签机向读取器发送RN16(即第二消息)时，可在RN16中携带第一时间信息，如图5所示的T1，该T1表示标签机发送RN16和接收ACK指令之间的时间间隔。 其中，标签机可根据自身的设备状态信息(包括是否延时收发信息、储能信息等)确定当前的储能信息是否与第一时刻相匹配，若不匹配，则可以将T1值调整至更大的值，比如增加10毫秒，并按照调整后的T1接收ACK指令。或者，标签机可以向读取器反馈供能时间因子，以使读取器根据供能时间因子将T1调整至更大的值。在T1这段时间内，标签机可以储备更多的能量。
可选地，标签机向读取器发送RN16时，也可在RN16中携带可收发的信息长度，比如ACK指令的信息长度、目标数据的数据长度等中的至少一项。读取器接收到RN16后，可根据RN16中携带的信息长度，确定发送ACK指令的第一时刻(对应图5中的T1)和/或接收目标数据的第二时刻(对应图5中的T2)，从而使标签机有更多的时间储能能量。
可选地，标签机发送RN16时，还可在RN16中携带自身的设备状态信息，该设备状态信息包括是否延时收发信息、储能信息等。读取器接收到RN16后，可根据RN16中携带的设备状态信息，确定是否按照T1和T2收发消息。若设备状态信息为标签机不延时收发消息，则T1、T2为0；若设备状态信息为第一设备延时收发消息，则读取器可根据其他信息(如标签机上报的储能信息、预先约定或配置好的T1和T2)确定出T1和T2的值，进而按照T1和T2与标签机收发消息。
在一个实施例中，如图6所示，读取器需从标签机中查询目标数据，则读取器首先向标签机发送查询指令(Query)，该查询指令即为第一消息。然后，标签机接收到查询指令后，生成一个16比特的随机字符(即RN16)，将RN16发送给读取器。然后，读取器通过ACK指令的形式将RN16反馈给标签机，以触发标签机向读取器发送目标数据。
可选地，标签机向读取器发送RN16时，可在RN16中携带第二时间信息，如图6所示的T3，该T3表示标签机发送RN16和发送目标数据之间的时间间隔。
可选地，标签机向读取器发送RN16时，可在RN16中携带如图6所示的T4，该T4表示标签机接收ACK和发送目标数据之间的时间间隔。
可选地，标签机向读取器发送RN16时，可在RN16中携带供能时间因子，以使读取器根据供能时间因子调整T3和T4的值。比如，若标签机当前的储能信息和调度时间需求(即T3和T4的值)不匹配，则可以向读取器上报供能时间因子，以使读取器调整大T3和T4的值，从而延后读取器发送ACK指令的时间，以及延后标签机发送目标数据的时间。
由上述实施例可看出，在读取器获取标签机中的目标数据并发出查询指令(Query)后，标签机并非是立即将目标数据发送至读取器，而是能够基于时间信息(比如图5-6所示的T1、T2、T3和T4)、标签机的设备状态信息和/或待收发消息的信息长度来确定收发 消息的时刻，因此，标签机在消息收发过程中能够有更多的时间来累积能量，从而在标签机能量充足(如具有足够的收发信号功率)的情况下进行消息收发，避免因标签机能量不足而影响消息收发效果或者无法收发消息的情况。因此，标签机在消息收发过程中能够有更多的时间来累积能量，从而在标签机能量充足(如具有足够的收发信号功率)的情况下进行消息收发，避免因设备能量不足而影响消息收发效果或者无法收发消息的情况。
