技术领域

背景技术
在现有的射频识别(Radio Frequency Identification，RFID)的盘点流程中，读取器(Reader)在同一个时刻通常只能接收一个标签(Tag)的反向散射信号。例如，在Reader发送控制命令开启盘点流程时，会指示一个数值Q。Tag在本地产生一个{0，…，2^Q-1}的数值中，随机选一个数值q。当前随机数值为0的Tag会响应Reader的控制命令，进行反向散射；然而，当前的随机数值不为0的Tag则不进行反向散射，而是等待下一次盘点，直到满足随机数值为0的条件才能进行反向散射。由于该随机因素的存在，导致Tag响应查询控制命令的效率变低，从而影响后续盘点流程的进行，最后导致通信效率不高。

为了方便理解，以下对本申请实施例涉及的一些内容进行说明：
一、反向散射通信(Backscatter Communication，BSC)，或，无源物联网(passive Internet of Things，passive IoT)通信
反向散射通信是指反向散射通信设备利用其它设备或者环境中的射频信号进行信号调制来传输自己信息。
反向散射通信设备，可以是：
(1)传统射频识别(Radio Frequency Identification，RFID)中的反向散射通信设备，一般是一个标签(Tag)，属于无源IoT设备(Passive-IoT)；
(2)半无源(semi-passive)的Tag，这类Tag的下行接收或者上行反射具备一定的放大能力；
(3)具备主动发送能力的Tag(active Tag)，这类终端可以不依赖对入射信号的反射向基站(gNB)或读取器(Reader)发送信息。
一种简单的实现方式为，Tag需要发送“1”时，Tag对入射载波信号进行反射，Tag需 要发送“0”时不进行反射。
反向散射通信设备通过调节其内部阻抗来控制电路的反射系数Γ，从而改变入射信号的幅度、频率、相位等，实现信号的调制。其中信号的反射系数可表征为：
其中，Z0为天线特性阻抗，Z1是负载阻抗。假设入射信号为Sin(t)，则输出信号为因此，通过合理的控制反射系数可实现对应的幅度调制、频率调制或相位调制。
可选地，本申请实施例中所述标签设备为上述反向散射通信设备。
可选地，本申请实施例中，第一传输可以是反向散射通信中的相关传输。
本实施例中，反向散射通信包括以下内容的传输：
(1)激励载波(Carrier Wave，CW)传输，也就是载波信号的传输；一种实施例中，该激励载波可以是由网络侧设备发送给标签(Tag)的，还可以是由终端发送给标签的。
(2)控制命令(command)的传输，例如：选取命令、查询命令、重复查询命令、答复命令、读取命令、写入命令、随机请求命令等；一种实施例中，该控制命令可以是由网络侧设备发送给标签(Tag)的，还可以是由终端发送给标签的。
可选地，所述控制命令可以包括以下至少一项：选择类型命令，查询类型命令，接入命令；其中，所述选择类型命令包括以下至少一项：选择命令(一个具体的选择命令)，盘点命令，排序命令；所述查询类型命令包括以下至少一项：查询命令(一个具体的查询命令)，调节查询命令，重复查询命令；所述接入命令包括以下至少一项：随机请求命令，读取命令，写入命令，销毁命令，锁定命令，访问命令，安全相关接入命令，文件管理相关接入命令。
选择类型(Select)命令是必备的，由于标签有多种属性，基于用户设定的标准和策略，使用选择类型命令，改变某些属性和标志就人为选择或圈定了一个特定的标签群，可以只对它们进行盘点识别或存取操作，这样有利于减少冲突和重复识别，加快识别速度。
盘点阶段的命令用于开始一次盘点。例如，查询命令用于启动一轮盘点，并决定哪些标记参与该轮盘点；调节查询命令用于将标签原来接收时刻(Slot)的数目进行调整；重复查询命令用于减少标签Slot的数字。
接入命令(Access)中，随机请求(Req_RN)命令要求标签产生一个随机数；读取命令用于从标签的存储中的某个位置读取资料；写入命令用于写入资料到标签的存储中；销毁命令可以隐私的泄漏，标签无法再使用；锁定命令用于标签不能再进行写入的动作，防止资料被任意的篡改；访问命令用于当标签拥有密码时候让标签从开启(Open)的状态转成保护(Secure)状态；安全相关接入命令用于保障标签安全；文件管理相关接入命令可以用于对标签内文件进行管理。
(3)反馈信息传输，在反向散射通信中，也可以理解为反向散射信息的传输，包括，例如：Tag标识信息(如查询过程中的临时代表Tag身份的16-bit随机数)、电子产品代码 信息、Tag状态信息等)。一种实施例中，该反向散射信道或信号可以是标签通过反向散射发送给终端的，还可以是标签通过反向散射发送给网络侧设备的。
二、控制命令
控制传输中包括如下至少一项操作，而每项操作中包括一个或多个相关的控制命令：
a、选择(Select)操作
读取器为后续盘点选择标签群或对标签群进行加密以进行后续认证的过程。选择包括选择命令；
b、盘点(Inventory)操作
读取器识别标签的过程。读取器通过在四个会话中的一个会话中发送查询命令来开始盘点循环。一个或多个标签可能回复。读取器检测单个标签应答，并请求协议控制(Protocol Control，PC)，可选的请求扩展协议控制(Extended Protocol Control，XPC)字、电子产品代码(Electronic Product Code，EPC)和循环冗余校验码-16(Cyclic Redundancy Check-16，CRC-16)。盘点中包含多个命令。其中，非常重要的命令为质询命令。具体参见下表2。
c、接入(Access)操作
读取器与单个标签进行交易(读取、写入、鉴权或以其他方式参与)的过程，在接入之前，读取器对标签进行单独识别，接入包括多个命令。
读取器(Reader)操作的指令如表1所示，操作类型如表2所示。
表1
具体地，控制命令可以包括如表2(控制命令及功用介绍对照表)所示的指令。
表2



Tag标签的状态如表3所示。
表3

现在超高频射频识别(Ultra High Frequency RFID，UHF RFID)的协议设计中，在盘点模式下，要求读取器发送查询指令(Query)后标签(Tag)响应回应(Reply)，即产生一个16-bit的随机数给读取器。然后读取器将该序列通过ACK指令发给Tag后，Tag将相关的数据发送给读取器。
具体的，获取Tag的编码信息(PC或EPC)流程如图2所示：
基站(gNB)向Tag发送控制命令(例如，Query)，以及CW。Tag接收Query后向gNB反馈RN16。gNB接收RN16后，进一步向Tag发送ACK，以及CW。Tag响应于ACK，上报PC或EPC。
三、Backscatter通信应用场景
Backscatter通信的应用场景包括：
1)网络侧设备发送CW和信令并接收Tag的反射信号。
2)终端发送CW和信令并接收Tag的反射信号。
3)网络侧设备发送CW和信令给Tag；终端接收Tag发送的反向散射信息。
4)终端发送CW和信令给Tag；网络侧设备接收Tag的反向散射信息。
该实施例中，网络侧设备，例如基站的类型包括但不限于：基站的类型包括集成接入与回传(Integrated Access and Backhaul，IAB)节点(IAB node)，中继器(repeater)如网络控制中继器(network controlled repeater)、杆站(pole station)。
四、反向散射通信系统的竞争性通信过程
在现有的反向散射通信系统中，Reader在同一个时刻通常只能接收一个Tag的反向散射信号。例如在RFID的盘点流程中，Reader发送控制命令(例如，query)开启盘点流程时，会指示一个数值Q。Tag在本地产生一个{0，…，2^Q-1}的数值中，随机选一个数值q。当前随机数值为0的Tag会响应Reader的控制命令，进行反向散射信号的传输。当前的随机数值不为0的Tag暂不进行反向散射信号的传输。Reader在完成和随机数值为0的Tag的通信之后，可以继续发送控制命令(例如，queryRep)，例如，指示Tag对生成的随机数减1，随机数值减为0的Tag响应该控制命令，进行反向散射传输。
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盘点处理方法、装置及设备进行详细地说明。
如图3所示，本申请实施例的一种盘点处理方法，包括：
步骤301，第一设备接收第一命令，所述第一命令用于盘点以及获取目标设备的编码信息。
这里，第一命令的功能包括两类，即一方面用于盘点，另一方面用于获取目标设备的编码信息。
步骤302，所述第一设备根据所述第一命令，确定是否反馈自身的编码信息。
本步骤中，第一设备根据步骤301接收到的第一命令，确定是否反馈自身的编码信息。其中，确定是否反馈自身的编码信息，也可以理解为确定自身是否为目标设备。
如此，按照上述步骤，第一命令同时用于盘点和获取目标设备的编码信息。由此，第一设备能够在接收到第一命令后，根据第一命令确定其是否为目标设备，从而确定是否反馈自身的编码信息。这实现了通过第一命令对反射散射设备进行盘点并获取目标设备编码信息，简化了盘点流程的时延与复杂度，有利于提高通信传输效率。
一种实施例中，第一设备为标签设备Tag；编码信息包括：协议控制(Protocol Control，PC)、电子产品代码(Electronic Product Code，EPC)等。
可选地，第一设备接收第二设备发送的第一命令，或者，接收经第三设备转发的第二设备发送的第一命令。这里，第二设备(Reader)为网络侧设备或终端设备，第三设备(即中继设备)为网络侧设备，终端，或IAB设备等。
可选地，该实施例中，第一设备确定反馈自身的编码信息后，反馈自身的编码信息。进一步地，向第二设备或第三设备反馈自身的编码信息。
可选地，该实施例中，所述第一命令指示以下至少一项：
所述目标设备的身份信息；
盘点相关指示信息。
一种实施例中，所述第一命令指示目标设备的身份信息，该身份信息可以是目标设备的16位身份信息(RN16)。
一种实施例中，盘点相关指示信息包括：选择命令、查询命令或重复查询命令中至少一项命令所包含的指示信息。例如，盘点相关信息还包括Q值的指示。又例如，盘点相关指示信息用于确定哪些第一设备参与本次盘点。
可选地，该实施例中，在所述第一设备接收第一命令之前，所述方法还包括：
所述第一设备接收第二命令，所述第二命令用于指示盘点模式；
其中，所述盘点模式包括两步盘点模式和四步盘点模式。
这里，四步盘点模式包括：1)所述第一设备接收质询相关命令；2)在所述第一设备的时隙计数器等于第一值(例如，0)的情况下，反馈RN16；3)所述第一设备接收编码获取命令(例如ACK)；4)所述第一设备反馈编码信息(例如，PC，EPC)。例如，如图2所示的步骤1-4。
两步盘点模式包括：1)所述第一设备接收第一命令；2)在所述第一设备为目标设备的情况下，反馈其编码信息。
作为一种实施方式，第二命令可以是选择命令或盘点命令。
可选地，该实施例中，所述第一设备接收第一命令，包括：
在所述第二命令指示盘点模式为两步盘点模式的情况下，所述第一设备接收所述第一命令。
也就是说，第一命令的发端设备(即第二设备)会在发送第一命令之前，会发送指示两步盘点模式的第二命令，此时，第一设备需要在接收到第二命令，且该第二命令指示两步盘点模式的情况下，接收第一命令，从而执行后续处理。当然，若第一设备接收到的第二命令指示四步盘点模式，第一设备会如图2所示流程进行处理，在此不再赘述。
此外，若预先约定第一命令的发端设备在第一命令发送前无需发送第二命令，即默认第一设备执行两步盘点流程。
可选地，该实施例中，所述第一设备根据所述第一命令，确定是否反馈自身的编码信息，包括：
在所述第一命令包括所述目标设备的身份信息的情况下，所述第一设备判断所述第一设备的身份信息是否与所述目标设备的身份信息相匹配；
在所述第一设备的身份信息与所述目标设备的身份信息相匹配的情况下，所述第一设备反馈自身的编码信息。
如此，第一设备能够在接收到第一命令后，根据第一命令确定是否反馈自身的编码信息，也就是该第一设备是否为目标设备，以保证仅有第一命令对应的目标设备反馈编码信息，避免多个第一设备同时进行编码信息的反馈。
即，第一设备会针对第一命令的目标设备的身份信息，通过第一设备的身份信息是否与所述目标设备的身份信息相匹配，来确定是否反馈自身的编码信息。具体的，在第一设备的身份信息与所述目标设备的身份信息相匹配的情况下，该第一设备反馈自身的编码信息。
当然，第一命令包括目标设备的身份信息，表明获取该目标设备的编码信息，此时，若第一设备为目标设备，其时隙计数器的取值可以忽略，也就是说其时隙计数器的取值不限。
可选地，该实施例中，在所述第一命令包括所述目标设备的身份信息的情况下，所述第一设备判断所述第一设备的身份信息是否与所述目标设备的身份信息相匹配，包括：
所述第一设备忽略所述盘点相关指示信息，并判断所述第一设备的身份信息是否与所述目标设备的身份信息相匹配
也就是，第一设备接收到第一命令，该第一命令包括目标设备的身份信息的情况下，如果所述第一设备确认为目标设备，则第一设备不受盘点相关指示信息的限制；该第一设备可以属于所述盘点相关指示确认的参与盘点的第一设备，也可以不属于参与本次盘点的第一设备。
另一实施例中，在所述第一设备的身份信息与所述目标设备的身份信息相匹配的情况 下，所述第一设备也必须遵循所述第一命令中的盘点相关指示信息的指示。
可选地，所述目标设备属于所述第一命令所确定的参与盘点的第一设备。
可选地，该实施例中，所述方法还包括：
在所述第一设备的身份信息与所述目标设备的身份信息不匹配的情况下，包括以下至少一项：
所述第一设备不反馈自身的编码信息；
所述第一设备的时隙计数器不进行递减；
所述第一设备的时隙计数器重置。
即，第一设备针对第一命令的目标设备的身份信息，通过第一设备的身份信息是否与所述目标设备的身份信息相匹配，在第一设备的身份信息与所述目标设备的身份信息不匹配的情况下，包括以下至少一项：该第一设备不反馈自身的编码信息；该第一设备的时隙计数器不进行递减；该第一设备的时隙计数器重置。
例如，第一设备接收到所述第一命令，且该第一设备的时隙计数器满足等于0，但只要该第一设备的身份信息与第一命令中目标设备的身份信息不匹配，该第一设备仍不能进行其编码信息的反馈。
例如，在所述第一设备的身份信息与所述目标设备的身份信息不匹配的情况下，所述第一设备的时隙计数器不进行递减。指的是，在第一命令指示了目标设备的身份信息的情况下，只有目标设备才会反馈编码信息，而其他非目标设备但参与本次盘点的第一设备将不会递减其时隙计数器。这相当于本轮盘点的是第一命令指定的目标设备，而非其他参与盘点的第一设备，则其他参与盘点的第一设备的状态以及计时器不需要变化(也就是保持现有状态)。
其中，时隙计数器重置指的是根据Q值重新生成随机数并加载到时隙计数器内。
可选地，该实施例中，在所述第一设备的身份信息与所述目标设备的身份信息未匹配的情况下，所述第一设备保持当前状态或转换到仲裁(arbitrate)状态。
这里，在第一设备的身份信息与所述目标设备的身份信息未匹配的情况下，第一设备的当前状态为reply状态或arbitrate状态。
可选地，所述第一设备根据所述第一命令，确定是否反馈自身的编码信息，包括：
在所述第一命令未包括所述目标设备的身份信息，且所述第一设备的时隙计数器等于第一值的情况下，所述第一设备反馈自身的编码信息。
这里，第一值可以是预先约定的，可以是第一命令指示的(如盘点相关指示信息中携带)。对于第一命令不包括目标设备的身份信息的情况，第一设备可以按照其时隙计数器的取值，在时隙计数器(取值)等于第一值时反馈自身的编码信息。
可以理解的是，在本实施例中，目标设备是接收到第一命令且确认反馈自身的编码信息的第一设备。具体地，目标设备有两种可能，1)在第一命令指示目标设备的身份信息的情况下，所述目标设备由第一命令所指定；2)在第一命令未指示目标设备的身份信息 的情况下，所述目标设备是满足时隙计数器等于第一值的第一设备。可选地，所述第一设备被第一命令确定参与本次盘点。
可选地，所述方法还包括：
所述第一设备转换到确认(acknowledged)状态。
也就是说，在确定第一设备反馈编码信息的情况下，该第一设备转换到确认状态。
可选地，该实施例中，第一设备还根据第一命令确定或递减自己的时隙计数器取值。例如，第一设备并非目标设备，第一设备也能够根据盘点相关指示信息，执行：确定是否参与本次盘点，确定是否递减自己的时隙计数器取值中的至少一项。
可选地，第一设备接收到第一命令所触发的反馈信息为编码信息。例如，PC，EPC。一种实施例中，第一设备接收到第一命令所触发的反馈信息不为RN16。
可选地，该实施例中，所述第一设备反馈自身的编码信息，包括：
所述第一设备基于连续波的接收来反馈自身的编码信息。
需要说明的是，第二设备在发送第一命令起的特定时间间隔内发送连续波(Continuous Wave)，供给第一设备进行编码信息的反馈。则第一设备基于该连续波的接收来反馈自身的编码信息。
另外，考虑到由于第一设备反馈的编码信息长度不固定，第二设备不确定该发送多长时间的连续波供给第一设备进行反馈。
作为一种实施方式，一方面，第二设备按照第二值来发送连续波供给第一设备进行反馈，其中，第二值是按照最长的编码信息长度确定的时长值。进一步，第二设备在检测不到反馈信息的情况下，停止发送连续波。另一方面，第二设备在接收到第一设备的结束符或结束序列之后，停止发送连续波，实现适应性的发送可变长度连续波，避免不必要的资源及能耗。其中，第一设备可以在发送完编码信息后附加发送该结束符或结束序列。该结束符或结束序列可以是预定义的，也可以是由第二设备配置的。
可选地，该实施例中，第二设备若未成功接收(包括接收失败以及接收到但未成功解码)目标设备的编码信息的情况下，第二设备会发送指示四步盘点模式的第二命令以及第三命令中的至少一项。
下面，说明本申请实施例的方法的具体应用：
示例一：
步骤1，第一设备(如标签设备)接收所述第一命令；
步骤2，所述标签设备根据接收到的上述第一命令，确定是否反馈所述标签设备的编码信息。在确定反馈的情况下，反馈所述标签设备的编码信息，例如PC、EPC。在确定不反馈的情况下，不反馈编码信息。
示例二：
步骤0，第一设备(如标签设备)接收所述第二命令；
步骤1，在所述第二命令指示盘点模式为两步盘点模式的情况下，所述标签设备接收 所述第一命令；
步骤2，所述标签设备根据接收到的上述第一命令，确定是否反馈所述标签设备的编码信息。在确定反馈的情况下，反馈所述标签设备的编码信息，例如PC、EPC。在确定不反馈的情况下，不反馈编码信息。
在上述示例中，确定反馈的情况包括以下任一项：
1)所述标签设备的身份信息与所述第一命令指示的目标设备的身份信息相匹配(例如，标签设备的RN16与第一命令中目标设备对应的RN16一致)；
2)所述第一命令未包括目标设备的身份信息，且所述标签设备的时隙计数器取值等于第一值(例如，第一值为0)。
在上述示例中，确定不反馈的情况包括以下任一项：
1)所述标签设备的身份信息与所述第一命令中目标设备的身份信息不匹配；
2)所述第一命令未包括目标设备的身份信息，且所述标签设备的时隙计数器取值不等于第一值(例如，第一值为0)。
需要说明的是，即使在接收到所述第一命令的情况下，所述标签设备的时隙计数器取值等于第一值，只要所述标签设备的身份信息与所述第一命令指示的目标设备的身份信息不匹配，所述标签设备仍不能进行其编码信息的反馈。
此外，所述标签设备在确定不反馈的情况下，包括不反馈编码信息、不进行时隙计数器的递减、以及重置时隙计数器中的至少一项。
另外，该实施例中，第一设备的身份标识与第一命令中所述目标标签的身份信息不匹配，或第一命令中未包括所述目标标签的身份标识，但该第一设备的时隙计数器取值不等于第一值的情况下，第一设备仍然可以根据第一命令指示的盘点相关指示信息确定是否参与本次盘点，若确定参与本次盘点，该第一设备能够在时隙计数器取值递减至第一值时，再反馈编码信息。
例如，上述示例二所述标签设备在确定不反馈的情况下，所述标签设备仍然可以根据第一命令指示的盘点相关指示信息确定是否参与本次盘点。
可选地，所述标签设备基于所述盘点相关指示信息确定参与本次盘点，且所述标签设备的时隙计数器取值等于第一值的情况下，所述标签设备仍不反馈其身份信息(如RN16)。也就是说，第一命令的Tag反馈信息只能是编码信息。
该实施例中，若第一设备和第二设备之间通信经由第三设备中继，本申请实施例方法的应用，例如如图4所示，第一设备对应Tag，第二设备对应网络侧设备gNB，第三设备对应终端UE。第一命令为Query(盘点相关指示信息)+ACK(目标设备的身份信息)，其中，ACK如果携带RN16(目标设备的16位身份信息)，可以理解为指示了目标设备，也就是触发目标设备进行编码信息(如PC/EPC1)的反馈。如果ACK不携带RN16，则目标设备为时隙计数器取值等于第一值(第一值为0，即Slot＝0，)的第一设备，由其进行PC/EPC1的反馈。这里，gNB发送的第一命令经由UE转发至Tag；而Tag确定反馈自身 的编码信息，其反馈的编码信息经由UE转发至gNB。
该实施例中，若第一设备和第二设备之间直接通信，本申请实施例方法的应用，例如如图5所示，第一设备对应Tag，第二设备对应网络侧设备gNB。同样的，第一命令为Query(盘点相关指示信息)+ACK(目标设备的身份信息)，其中，ACK如果携带RN16(目标设备的16位身份信息)，可以理解为指示了目标设备，也就是触发目标设备进行编码信息(如PC/EPC1)的反馈。如果ACK不携带RN16，则目标设备为时隙计数器取值等于第一值(第一值为0，即Slot＝0，)的第一设备，由其进行PC/EPC1的反馈。这里，gNB直接发送第一命令至Tag；而Tag确定反馈自身的编码信息，其直接反馈编码信息至gNB。
可选地，该实施例中，第一命令触发的第一设备的反馈(Tag reply)的格式与四步盘点流程中编码获取命令(ACK)触发的Tag reply的格式相同，在此不再赘述。
综上，本申请实施例的盘点处理方法，能够通过第一命令，实现两步查询目标设备的编码信息，该目标设备可以是与第一命令指示的身份信息对应的第一设备，也可以是第一命令未指示设备身份信息时，时隙计数器取值等于第一值的第一设备。从而，减少通信的时延与流程复杂度，有利于提高通信传输效率。
如图6所示，本申请实施例一种盘点处理方法，包括：
步骤601，第二设备发送第一命令，所述第一命令用于盘点以及获取目标设备的编码信息。
如此，第二设备通过发送第一命令，能够使第一设备在接收到第一命令后，根据第一命令确定是否反馈自身的编码信息，也就是该第一设备是否为目标设备，以保证仅有第一命令对应的目标设备反馈编码信息，避免多个第一设备同时进行编码信息的反馈，减少通信的时延与流程复杂度，有利于提高通信传输效率。
可选地，所述第一命令包括以下至少一项：
所述目标设备的身份信息；
盘点相关指示信息。
可选地，在所述第二设备发送第一命令之后，所述方法还包括：
所述第二设备接收目标设备反馈的编码信息。
这里，目标设备可以是与第一命令指示的身份信息对应的第一设备，也可以是第一命令未指示设备身份信息时，时隙计数器取值等于第一值的第一设备。
可选地，在所述第二设备发送第一命令之前，还包括：
所述第二设备发送第二命令，所述第二命令用于指示盘点模式。
可选地，所述方法还包括：
在所述第二设备未成功接收所述目标设备的编码信息的情况下，所述第二设备发送以下至少一项：
第二命令，所述第二命令用于指示盘点模式且指示的盘点模式为四步盘点模式；
第三命令，所述第三命令为选择命令或查询命令。
可选地，所述方法还包括：
所述第二设备在发送第一命令起的特定时间间隔内发送连续波。
需要说明的是，该实施例的方法与上述第一设备执行的方法配合实现，上述方法实施例的实现方式适用于该方法，也能达到相同的技术效果。
如图7所示，本申请实施例的一种盘点处理方法，包括：
步骤701，第三设备接收目标设备反馈的编码信息，所述目标设备为接收到第一命令，且确认反馈自身的编码信息的第一设备；其中，所述第一命令用于盘点以及获取目标设备的编码信息。
即，第三设备作为第一设备和第二设备之间通信的中继，会通过接收目标设备反馈的编码信息，该目标设备是接收到第一命令且确认反馈自身的编码信息的第一设备，以便告知第二设备。
可选地，在所述第三设备接收目标设备反馈的编码信息之前，所述方法还包括：
第三设备接收第二设备发送的第一命令；
所述第三设备向第一设备发送所述第一命令。
