下行通信模块 11 , 与下行家庭局域网 （ Home area network, HAN )的终端 设备连接， 用于与终端设备通信。
可以理解， 当上行通信模块 10接收到上行数据后， 电力网关需要先对下行 数据进行解封装， 然后再确定解封装后的下行数据是否为终端设备的信息， 而 电力网关对下行数据的解封装可以由上行通信模块 10或控制单元 12来执行。则 在具体地实施例中：
( 1 ) 当对下行数据的解封装由上行通信模块 10来执行， 则： 上行通信模 块 10用于接收上行网元发送的下行数据，并将该下行数据解封装后传送给控制 单元 12,控制单元 12具体用于根据解封装后的下行数据确定是否为获取终端设 备的信息；

进一步地，上述电力网关中的控制单元 12确定下行数据为获取终端设备的 信息时，如果电力网关中储存终端设备的信息， 则电力网关需要将终端设备的 信息发送给上行网元， 而可以不需要向终端设备去获取， 具体地， 需要先将该 终端设备的信息使用上行通信模块 10与上行网元之间的通信协议进行封装，然 后将封装后的终端设备的信息发送给上行网元。而电力网关对终端设备的信息 进行的封装可以由上行通信模块 10或控制单元 12来执行。 则在具体地实施例 中：

更进一步地，上述电力网关中的控制单元 12确定下行数据为获取终端设备 的信息时， 如果电力网关中未储存终端设备的信息， 则电力网关需要将获取终 端设备的信息发送给终端设备来获取， 具体地， 需要先将该获取终端设备的信 息使用下行通信模块 11与终端设备之间的通信协议进行封装，然后将封装后的 获取终端设备的信息发送给终端设备。而电力网关对获取终端设备的信息进行 的封装可以由下行通信模块 11或控制单元 12来执行。 则在具体地实施例中：
( 1 ) 当封装操作由下行通信模块 11来执行， 则： 控制单元 12用于当电 力网关中未储存终端设备的信息时，将获取终端设备的信息传送给下行通信模 块 11 , 下行通信模块 11封装获取终端设备的信息， 并将封装后的获取终端设 备的信息发送给终端设备；
( 2 )如果下行通信模块 11的处理能力有限， 则封装操作可以由控制模块 12来执行， 则： 控制单元 12用于当电力网关中未储存终端设备的信息， 将获 取终端设备的信息进行封装后， 传送给下行通信模块 11 , 由下行通信模块 11 将封装后的获取终端设备的信息发送给终端设备。 可见， 本发明实施例的电力网关中， 连接下行通信模块 11和上行通信模块 10的控制单元 12可以根据上行网元发送给终端设备的下行数据的具体内容进 行处理后， 并将处理结果比如上述终端设备的信息返回给上行网元， 可以节省 传输到终端设备的数据流量，使得该电力网关可以通过控制单元 12对下行数据 进行控制， 从而可以控制终端设备与上行网元之间的数据传输。
进一步地， 在上述电力网关中， 当控制单元 12确定下行数据为对终端设 备的控制信息， 将该控制信息传送给下行通信模块 11以发送给终端设备； 当 控制单元 12确定下行数据为对该电力网关的配置信息， 才艮据配置信息对电力 网关进行配置。其中对终端设备的控制信息可以指示对终端设备的操作进行的 控制， 比如要求终端设备以一定的周期发送状态信息， 或要求终端设备发送当 前状态信息等； 而对电力网关的配置信息可以是指电力网关传输数据等参数， 比如电力网关接入的流量信息或终端设备数量或电力网关上传数据的流量信 息等， 这样可以对接入到上行网络的流量进行限制。
需要说明的是， 本实施例中， 电力网关在发送上述的控制信息给终端设备 时， 需要先对控制信息使用下行通信模块 11与终端设备之间的通信协议进行 封装， 并将封装后的控制信息发送给终端设备， 则具体地对控制信息的封装可 以由控制单元 12或下行通信模块 11来执行。
在另一个具体的实施例中， 电力网关中的下行通信模块 11还用于接收终 端设备发送的上行数据， 当控制单元 12确定上行数据为对下行数据的响应信 息， 将该响应信息传送给上行通信模块 10; 当控制单元 12确定终端设备发送 的上行数据为终端设备上报的状态信息或组网信息，则控制存储模块储存状态 信息或组网信息。
其中，对下行数据的响应信息可以为对上行网元发送的读取命令或控制信 息等的响应， 比如接收到读取命令的响应消息等； 终端设备上报的状态信息可 以指终端设备的电量或走字状态等；组网信息可以指终端设备在网络中的参数 比如是否在网的信息等， 控制单元 12可以控制存储模块对终端设备上报的状 态信息或组网信息进行储存，这样可以在需要的时候才将该状态信息或组网信 息发送给上行网元， 緩减了终端设备与上行网元之间的数据传输。
需要说明的是， 电力网关在接收到终端设备的上行数据并进行处理时， 需 要先对上行数据进行解封装，具体地对上行数据的解封装可以由下行通行模块
11来执行， 但是如果下行通信模块 11的处理能力有限时， 对上行数据的解封 装可以由控制单元 12或上行通信模块 10来执行；如果上行数据为下行数据的 响应信息， 则在发送该响应信息给上行网元时， 需要由上行通信模块 10或控 制单元 12使用上行通信模块 10与上行网元之间的通信协议对响应信息进行封 装后发送。
可以理解， 在上述的电力网关中还可以包括存储模块 13 , 比如可以为存储 据， 比如上述的对电力网关的配置信息、终端设备上报的组网信息或状态信息 等，且在另一个具体的实施例中该存储模块 13可以不用包括在电力网关中， 而 是外挂到电力网关上， 这样可以节省电力网关的体积及功耗。
需要说明的是， 上述控制单元 12可以是微控制单元（ Micro Control Unit, MCU ); 上行通信模块 10可以包括但不限于通用分组无线服务技术（General Packet Radio Service, GPRS )通信模块，长期演进（ Long Term Evolution, LTE ) 通信模块， 码分多址（Code Division Multiple Access, CDMA )通信模块， 演 进数据 ( Evolution Data Only, EVDO )通信模块， 时分同步码分多址接入（ TD - SCDMA )通信模块，宽带码分多址（ Wideband Code Division Multiple Access, WCDMA )通信模块，或全球移动通信（ Global System of Mobile communication, GSM )等其他无线通信模块，具体的，上行通信模块可以包括射频单元、 MCU 和存储单元等，其中射频单元主要是用来发送上行数据和接收下行数据； MCU 用来控制射频单元和存储单元， 比如进行启动的控制等， 且 MCU还可以用来 对上行数据封装和对下行数据解封装等操作； 上述的下行通信模块 11可以是 短距离通信模块，比如无线保真（ Wireless Fidelity, Wi-Fi )通信模块或 Zigbee 通信模块等， 其中， Zigbee通信模块可以包括射频单元、 MCU和存储单元等， 其中射频单元主要是用来接收上行数据和发送下行数据； MCU用来控制射频 单元和存储单元，还可以用于对上行数据解封装和对下行数据封装等。 一般来 说，上行通信模块 10中所包括的 MCU会比下行通信模块 11中所包括的 MCU 在一个具体的应用例中：当电力网关的上行通信模块 10接收到上行网元发 送的下行数据， 对该下行数据进行解封装后传送给控制单元 12; 控制单元 12 根据该下行数据的内容确定需要读取电表当前的走字参数，则将该解封装后的 下行数据进行封装后传送给下行通信模块 11 ;下行通信模块 11将封装后发送给 电表。
当电力网关的下行通信模块 11接收到电表发送的上行数据，将该上行数据 传送给控制单元 12; 控制单元 12对上行数据进行解封装后，根据该上行数据的 内容确定为电表上报的组网信息如是否在网等信息，则控制存储模块 13储存该 组网信息。
本发明实施例还提供另一种电力网关， 可以将至少一个终端设备（比如电 表或气表等）接入到上行网络中，来控制终端设备与上行网元之间的数据传输， 本实施例的电力网关中， 将根据数据的具体内容进行的处理（例如， 确定下行 数据是对电力网关的配置还是对终端设备的控制等 )集成到上行通信模块 20, 或集成到上行通信模块 20和下行通信模块 21中， 其结构示意图如图 2所示， 该电力网关， 包括：
上行通信模块 20连接与终端设备通信的下行通信模块 21 (例如： 上行通 信模块 20可以与下行通信模块 21通信 ),用于接收上行网元发送的下行数据， 终端设备的信息， 将该终端设备的信息发送出去； 若电力网关中未储存该终端 设备的信息， 将所述获取该终端设备的信息传送给下行通信模块 21。
其中， 上行通信模块 20可以先对下行数据进行解封装， 然后根据解封装 后的下行数据确定是否为获取终端设备的信息， 而上行通信模块 20在将终端 设备的信息发送出去时， 需要先对终端设备的信息进行封装， 然后将封装后的 终端设备信息发送给上行网元。
可以理解， 如果电力网关中未储存该终端设备的信息， 需要将该下行数据 即获取终端设备的信息发送给终端设备来获取，即先对获取终端设备的信息进 行封装然后再发送，具体地这里的封装操作可以由上行通信模块 20或下行通信 模块 21来执行， 则在具体的实施例中：
( 1 )如果封装操作由下行通信模块 21来执行， 则上行通信模块 20用于 若电力网关中未储存终端设备的信息，将获取终端设备的信息传送给下行通信 模块 21 , 下行通信模 21封装该获取终端设备的信息， 并发送给终端设备；
( 2 )如果封装操作由上行通信模块 20来操作， 则上行通信模块 20用于 若电力网关中未储存终端设备的信息， 将获取终端设备的信息封装后，传送给 下行通信模块 21， 通过下行通过模块 21发送给终端设备。
需要说明的是， 上述实施例中的封装可以由上行通信模块 20执行， 也可 以由下行通信模块 21执行， 优选的由上行通信模块 20执行封装操作。 另， 如 果下行通信模块 21的能力有限， 可以由上行通信模块 20执行封装操作。
在一个具体的实施例中， 当上行通信模块 20确定下行数据为对终端设备 的控制信息， 将该控制信息传送给下行通信模块 21 , 则下行通信模块将该控 制信息发送给终端设备； 当上行通信模块 20确定下行数据为对电力网关的配 置信息， 根据该配置信息对电力网关进行配置。
进一步地， 上述电力网关中的下行通信模块 21还用于接收终端设备发送 的上行数据， 当上行通信模块 20确定上行数据为对下行数据的响应信息， 将 响应信息发送出去， 即对该响应信息进行封装后发送给上行网元； 当上行通信 模块 20确定上行数据为终端设备上报的状态信息或组网信息， 储存状态信息 或组网信息。 其中上行通信模块 20对响应信息进行的封装是按照上行通信模 块 20与上行网元之间的通信协议进行封装； 另， 电力网关在接收到上行数据 时， 需要先对上行数据进行解封装， 具体解封装的操作可以由下行通信模块 21或上行通信模块 20来执行。
在具体实现时，可以将根据上行数据和下行数据的具体内容进行的处理的 功能集成到上行通信模块 20所包括的控制模块比如 MCU中， 这样上行通信 模块 20中所包括的 MCU不仅可以对下行数据进行解封装操作及对上行数据 进行封装，还可以根据下行数据和上行数据中的具体进行的处理比如根据下行 数据确定该下行数据具体是什么对电力网关的配置还是获取终端设备的信息 等， 从而可以充分地利用上行通信模块 20的资源空间。
其中， 上行通信模块 20在储存上述的组网信息或状态信息时， 可以直接 储存到上行通信模块 20中所包括的存储单元中， 可以不需要另外外挂的数据 存储单元。且本发明实施例中终端设备上报的组网信息或状态信息， 获取终端 设备的信息，对电力网关的配置信息， 下行数据的响应信息和对终端设备的控 制信息如图 1对应实施例中所述， 在此不进行赞述。
具体地， 上述上行通信模块 20可以是无线通信模块 (包括但不限 GPRS通 信模块， LTE通信模块， CDMA通信模块， EVDO通信模块， TD - SCDMA通 信模块， WCDMA通信模块， 或 GSM通信模块等）， 下行通信模块 21可以是短 距离通信模块， 比如 Wi-Fi通信模块或 Zigbee通信模块等。
在一个具体的应用例中， 终端设备可以为电表， 电力网关包括无线通信模 块， Zigbee通信模块， 无线通信模块与 Zigbee通信模块连接。 当电力网关的无 线通信模块接收到上行网元发送的下行数据，对该下行数据进行解封装后，根 据该下行数据的内容确定为需要读取电表当前的走字参数（例如电表的读数）， 则将该解封装后的下行数据传送给 Zigbee通信模块； Zigbee通信模块将该解封 装后的下行数据进行封装后发送给电表； 当电力网关的 Zigbee通信模块接收到 电表发送的上行数据， Zigbee通信模块将该上行数据传送给无线通信模块， 无 线通信模块将该上行数据进行解封装后 ,根据该上行数据的内容确定为电表上 报的组网信息如是否在网等信息， 则储存该组网信息。
在另一个具体的应用例中：当电力网关的上行通信模块 20接收到上行网元 发送的下行数据，对该下行数据进行解封装后，根据该下行数据的内容确定为 对电力网关的配置信息， 包括接入电力网关的终端数量等信息， 则上行通信模 块 20对下行通信模块 21中所包括的 MCU进行配置， 使其控制下行通信模块 21 接收终端设备的上行数据的情况， 具体地， 可以配置该 MCU在与下行通信模 块 21通信的终端设备的数据超过上述配置信息中终端数量时，控制下行通信模 块 21中的射频单元停止接收其它终端设备发送的上行数据， 另， 上行通信模块 20可以储存该配置信息；当电力网关的下行通信模块 21接收到电表发送的上行 数据，将上行数据传送给上行通信模块 20, 由上行通信模块 20对该上行数据进 行解封装后 ,并根据该解封装后的上行数据的内容确定为对上行网元的响应信 息，则将该响应信息使用上行通信模块 20与上行网元之间的通信协议封装后发 送给上行网元。
可见， 在本发明实施例的电力网关中， 上行通信模块 20和下行通信模块 21 可以直接通信， 不需要控制单元处理， 而是将根据下行数据和上行数据的 具体内容进行的处理功能集成到上行通信模块 20中， 这样可以充分地利用了 上行通信模块的资源，且节省了通信设备的体积， 且由于节省了多余的控制单 元的运行， 从而减少了电力网关的功耗。
上述实施例的电力网关中，将根据下行数据和上行数据的具体内容进行的 处理功能集成到上行通信模块 20中， 在其它具体的实施例中， 将根据数据的 具体内容进行的处理功能在上行通信模块 20和下行通信模块 21中的集成还可 以有以下的几种情况：
( 1 )将部分处理功能集成到上行通信模块 20中，将另一个部分处理功能 集成到下行通信模块 21中：
一种具体的实现包括：将根据上行数据的具体内容进行的处理集成到下行 通信模块 21 中， 将根据下行数据的具体内容进行的处理集成到上行通信模块 21中。则本实施例中，下行通信模块 21除了可以将上述获取终端设备的信息， 或对终端设备的控制信息发送给终端设备，还用于接收终端设备发送的上行数 据，对上行数据解封装后， 当确定解封装后的上行数据为对下行数据的响应信 息， 将该响应信息传送给上行通信模块 20; 当下行通信模块 21确定解封装后 的上行数据为终端设备上报的状态信息或组网信息，储存该状态信息或组网信 息。 而上行通信模块 20除了用于根据下行数据的具体内容进行处理之外， 还 用于将接收到的响应信息发送给上行网元。其中电力网关将响应信息发送给上 行网元时， 需要先对响应信息进行封装然后再发送， 而该封装的操作可以由上 行通信模块 20或下行通信模块 21来执行。
这样上行通信模块 20负责根据下行数据的具体内容进行处理， 而下行通 信模块 21 负责根据上行数据的具体内容进行处理， 且两个通信模块具体的处 理不相同。这样相对于将根据下行数据和上行数据的具体内容进行的处理功能 都集成到上行通信模块 20的技术方案来说，可以平衡上行通信模块 20和下行 通信模块 21的资源利用率， 适当地分担了上行通信模块 20的处理负担。
( 2 )将所有处理功能分别都集成到上行通信模块 20和下行通信模块 21 中， 这种情况下， 可以按照上行通信模块 20和下行通信模块 21的实际运行情 况来进行处理， 具体地， 在本实施例中：
上行通信模块 20, 用于在接收到下行数据后， 如果上行通信模块 10当前 的资源占用率大于预置的值控制下行通信模块 21对下行数据进行包括对获取 终端设备的信息、 对电力网关的配置信息和对终端设备的控制信息等处理。 进一步地， 当下行通信模块 21接收到终端设备的上行数据后， 如果下行 通信模块 21当前的资源占用率大于预置的值，则控制上行通信模块 20对上行 数据进行包括对终端设备上报的组网信息或状态信息，和对下行数据的响应信 息的处理等。
其中上行通信模块 20在确定当前的资源占用率是否大于预置的值时， 具 体是确定在上行通信模块 20中所包括的控制模块运行时占用的资源， 同样， 下行通信模块 21需要确定下行通信模块 21中所包括的控制模块运行时占用的 资源。
在一个具体的实现过程中， 上述的上行通信模块 20可以通过如下的结构 来实现， 结构示意图如图 3所示， 包括：

其中， 第一封装 /解封装单元 220 可以先把获取终端设备的信息封装后， 传送给下行通信模块 21。
则上述第一射频单元 210, 还用于将封装后的所述终端设备的信息发送给 所述上行网元。
上行通信模块 20中还可以包括： 第一配置处理单元 240, 用于当确定解 封装后的下行数据为对电力网关的配置信息，才艮据所述配置信息对所述电力网 关进行配置； 第一控制处理单元 250, 用于当确定解封装后的下行数据为对终 端设备的控制信息， 将控制信息传送给下行通信模块 21。
这样在上行通信模块 20中可以集成根据下行数据的具体内容进行处理的 单元， 即第一获取处理单元 230、 第一配置处理单元 240和第一控制处理单元 250, 且这些单元可以与第一封装 /解封装单元 220集成到一个硬件上比如都集 成到 MCU上。 在这种情况下， 可以由下行通信模块 21对解封装后的上行数 据根据上行数据的具体内容进行处理，具体可以包括对终端设备上报的组网信 息或状态信息， 及对下行数据的响应信息的处理。
进一步地， 参考图 4所示， 在上行通信模块 20中还可以集成根据上行数 据的具体内容进行处理的单元，包括第一响应处理单元 260和第一上^艮处理单 元 270, 其中： 第一响应处理单元 260用于当确定解封装后的上行数据为对下 行数据的响应信息， 控制第一封装 /解封装单元 220将响应信息进行封装， 并 由第一射频单元 210将封装后的响应信息发送给上行网元；第一上报处理单元 270用于当确定解封装后的上行数据为终端设备上报的状态信息或组网信息， 控制存储单元储存状态信息或组网信息。
需要说明的是， 上行通信模块 20中还可以包括其他的单元， 比如内部的 flash,存储单元和资源确定单元等， 该存储单元可以储存上述的终端设备上报 的组网信息或状态信息， 及对电力网关的配置信息； 资源确定单元可以在第一 射频单元 210接收到下行数据后， 确定上行通信模块 20的资源占用率， 如果 资源占用率大于预置的值， 第一封装 /解封装单元 220将下行数据进行解封装 后传送给下行通信模块 21 , 以根据解封装后的下行数据的具体内容进行处理， 如果资源占用率小于或等于预置的值， 则由上行通信模块 20进行处理。
在另一个具体的实施例中， 上述的下行通信模块 21可以通过如下的结构 来实现， 结构示意图如图 5所示， 包括：
第二射频单元 211 , 用于接收终端设备发送的上行数据； 该第二射频单元 211 是用来发送或接收数据， 该第二射频单元 211 可以包括天线和集成芯片 ( IC )等。
第二封装 /解封装单元 221 , 用于对上行数据进行解封装.
第二响应处理单元 231 , 用于当确定解封装后的上行数据为对下行数据的 响应信息， 将响应信息传送给上行通信模块 20。
第二上报处理单元 241 , 用于当确定解封装后的上行数据为终端设备上报 的状态信息或组网信息， 控制存储单元储存该状态信息或组网信息。
这样在下行通信模块 21中可以集成根据下行数据的具体内容进行处理的 单元即第二响应处理单元 231和第二上 ^艮处理单元 241 , 且这些处理的单元可 以与第二封装 /解封装单元 221集成到一个硬件上比如都集成到 MCU上；在这 种情况下， 可以由如图 3所示的上行通信模块 20根据解封装后的下行数据的 具体内容进行处理。 在其它情况下， 在下行通信模块 21中也可以集成其它的 处理单元， 比如根据上行数据的具体内容进行处理的单元等。
需要说明的是， 下行通信模块 21 中还可以包括其他的单元， 比如内部的 息或状态信息等。
本发明实施例还提供另一种电力网关， 可以将至少一个终端设备（比如电 表或气表等）接入到上行网络中，来控制终端设备与上行网元之间的数据传输， 本实施例的电力网关中，将根据数据的具体内容进行的处理功能可以集成到下 行通信模块 21 , 或集成到上行通信模块 20和下行通信模块 21 中， 其结构示 意图可以如图 2所示， 包括：
上行通信模块 20, 连接下行通信模块 21 (例如： 上行通信模块 20与下行 通信模块 21通信）， 用于与上行网元通信。

其中， 具体地， 上行通信模块 20可以接收上行网元发送的下行数据， 将 该下行数据传送给下行通信模块 21 , 而下行通信模块 21需要先对下行数据解 封装， 然后再确定解封装后的下行数据是否为获取终端设备的信息； 或上行通 信模块 20将该下行数据解封装后发送给下行通信模块 21进行处理。而下行通 信模块 21在传送终端设备的信息给上行通信模块 20时，可以先使用上行通信 模块 20与上行网元之间的通信协议进行封装后传送给上行通信模块 20。
在一个具体的实施例中， 当下行通信模块 21确定下行数据为对终端设备 的控制信息， 将该控制信息封装后发送给终端设备； 当下行通信模块 21确定 下行数据为对电力网关的配置信息， 根据配置信息对电力网关进行配置。
进一步地， 下行通信模块 21还用于接收终端设备发送的上行数据， 对上 行数据解封装后，并根据解封装后的上行数据的具体内容进行处理，具体包括： 当确定解封装后的上行数据为对下行数据的响应信息，将该响应信息传送给上 行通信模块 20, 当下行通信模块 21确定解封装后的上行数据为终端设备上报 的状态信息或组网信息， 储存状态信息或组网信息。
需要说明的是， 在具体实现时， 上述上行通信模块 20可以是 GPRS等无 线通信模块， 下行通信模块 21可以是短距离通信模块， 比如 Wi-Fi通信模块 或 Zigbee通信模块等； 另， 下行通信模块 21可以将根据解封装后的上行数据 和下行数据的具体内容进行处理过程中的数据直接储存到下行通信模块 21中 所包括的存储单元， 而不需要另外外挂的数据存储单元。
在一个具体的应用例中：当电力网关的上行通信模块 20接收到上行网元发 送的下行数据，对该下行数据进行解封装后传送给下行通信模块 21 ; 下行通信 模块 21根据该下行数据的内容确定为对电表的控制信息，包括电表上报状态信 息的周期等信息，则下行通信模块 21会将该控制信息使用下行通信模块 21与电 表之间的通信协议封装后发送给电表。
当电力网关的下行通信模块 21接收到电表发送的上行数据，对该上行数据 进行解封装后，根据该上行数据的内容确定为上报的状态信息， 比如当前的电 量信息等， 则将该状态信息传送给上行通信模块 20; 上行通信模块 20将该状态 信息使用上行通信模块 20与上行网元之间的通信协议封装后发送给上行网元。
可见， 在本发明实施例的电力网关中， 上行通信模块 20和下行通信模块 21 可以直接通信， 将根据下行数据和上行数据的具体内容进行的处理功能集 成到下行通信模块 21中， 这样可以充分地利用了下行通信模块 21的资源，且 节省了通信设备的体积， 且由于节省了多余的控制模块的运行，从而减少了电 力网关的功耗。

这样上行通信模块 20可以负责根据上行数据的具体内容进行的处理， 而 下行通信模块 21可以负责根据下行数据的具体内容进行的处理， 且两个通信 模块具体的处理可以不相同。这样相对于将根据下行数据和上行数据的具体内 容进行处理功能都集成到下行通信模块 21的技术方案来说， 可以平衡上行通 信模块 20和下行通信模块 21的资源利用率， 适当地分担了下行通信模块 21 的处理负担。

本发明实施例还提供一种电力网关的通信方法，主要是如图 1到图 8任一 个图所示的电力网关所执行的方法， 流程图如图 9所示， 包括：
步骤 101 , 电力网关接收上行网元发送的下行数据， 当确定下行数据为获 取终端设备的信息时， 电力网关可以执行步骤 102或步骤 103。
可以理解， 电力网关需要先对下行数据进行解封装， 然后再确定该解封装 后的下行数据是否为获取终端设备的信息。
步骤 102, 若电力网关中储存该终端设备的信息， 将该终端设备的信息发 送给上行网元， 具体地， 可以使用电力网关与上行网元之间的通信协议对将该 终端设备的信息进行封装后发送给上行网元。
