根据天线接口标准组织(antenna interface standards group，AISG)协议规定，基站与ALD之间的控制信号可以通过RS485线缆或者通过同轴线缆连接并传输。在实际应用中，ALD控制信号可以由单独的线缆传输；也可以将控制信号与射频信号合路在射频线缆中传输，信号接收端需将控制信号分离出来，技术上较为复杂。如图1所示，现有技术中，基站通过远端射频单元(remote radio unit，RRU)与ALD通过线缆进行连接，一个ALD与至少一个RRU连接，当存在多个ALD时，ALD之间可以通过线缆级联。

具体实施方式
本申请实施例提供了一种天线设备ALD与基站远端射频单元RRU连接的方法，用于传输ALD控制信号，避免施工人员连接电缆耗时费力，降低施工难度。
请参阅图2，为本申请实施例中ALD与基站连接方式示意图。
ALD包括电调控制器、TMA、升压器、驻波比测量单元和其他塔顶设备，一般随天线一起安装塔上，基站需要对有源的ALD进行管理，例如调节电调天线的角度，调节查询天线的倾角，或查询天线姿态等。基站可以是分布式基站，即射频处理单元和传统宏基站基带处理单元(base band unit，BBU)分离的基站，也可以是RRU与BBU集中的基站，例如宏基站、微基站等，具体此处不做限定。在本申请实施例中，以基站通过RRU与ALD进行连接为例进行说明，基站可以包括一个RRU或者多个RRU，基站中RRU的数量具体不做限定。RRU是基站的远端射频单元，可以用于对信号进行处理，基站通过RRU与ALD进行通信，可以根据遵循AISG协议规范与ALD通信，也可以根据需要由基站厂商和天线厂商协商自定义命令与ALD通信。
本申请实施例中，ALD配置了无线通信模块，该无线通信模块可以是蓝牙模块、无线保真(wireless fidelity，WIFI)模块、紫蜂(ZigBee)模块或物联网(internet of things，IOT)模块，其中，IOT模块包括低功耗广域网络模块(low-power wide-area network，LPWAN)，例如可以是工作于授权频段的窄带物联网(narrow band internet of things，NBIOT)模块、基于LTE演进的物联网(LTE-machine-to-machine，LTE-M)模块；也可以是工作于非授权频段的Sigfox模块和LoRa模块等，此处对于无线通信模块的具体类型不做限定。该无线通信模块可以集成在ALD内部，例如可以集成在TMA中或者远程控制单元(remote control unit，RCU)中；或者与ALD通过接头连接，例如可以是通过ALSG-RS485或AISG-OOK接头与ALD连接。此处对于无线通信模块与ALD连接的具体形式不做限定。一个基站配备的ALD可以有一个或者多个，本申请实施例中，对于ALD的数量不做限定，一个ALD至少与一个RRU进行连接。
RRU也配置了无线通信模块，该无线通信模块可以是蓝牙模块、WIFI模块、ZigBee模块或IOT模块。其中，IOT模块包括LPWAN模块，例如可以是NBIOT模块、LTE-M模块、Sigfox 模块或LoRa模块等，此处对于无线通信模块的具体类型不做限定。需要说明的是，RRU无线通信模块与ALD无线通信模块应为同类型的无线通信模块，可以相互匹配进行连接。该无线通信模块可以集成在RRU内部；或者与RRU通过外部接头连接，例如可以是ALSG-RS485和AISG-OOK接头。此处对于无线通信模块与RRU连接的具体形式不做限定。
如图2所示，ALD与基站通过无线通信模块建立无线通信链路并传递控制信号，本申请实施例中，基站通过RRU与ALD连接，当存在多个RRU需要与ALD连接时，例如存在RRU1和RRU2，ALD的无线通信模块可以与RRU1的无线通信模块之间建立无线通信链路，ALD的无线通信模块还可以与RRU2的无线通信模块之间建立另一条无线通信链路；当存在多个ALD时，例如存在ALD1、ALD2和ALD3，ALD1的无线通信模块可以与RRU的无线通信模块之间建立无线通信链路，ALD2的无线通信模块也可以与RRU的无线通信模块之间建立另一条无线通信链路，此外，ALD3可以通过无线通信模块与ALD2级联，通过ALD3与ALD2之间的无线通信链路以及ALD2与RRU之间的无线通信链路实现RRU与ALD3之间的控制信号传输。
本申请实施例提供了ALD与基站接口的无线连接方式，在层1,2和层7三层协议模型中，对层1物理层中通过线缆连接的方式扩充了无线连接方式，而对于层2数据链路层和层7应用层则未进行改变。
在通信网络中，基站负责接收、处理与发送无线信号，以及无线信号与易于传输的光电有限传输信号之间的转换。其中，基站的一个重要功能是需要对ALD进行相应控制以满足工作需要，例如调节电调天线的角度，调节查询天线的倾角，或查询天线姿态等。
在图2所示的ALD与基站连接方式示意图的基础上，请参阅图3，本申请实施例中ALD与基站的连接方法的一个实施例示意图。
301、ALD与基站建立无线通信链路；
由于本申请实施例中ALD包含无线通信模块，基站也包含无线通信模块，无线通信模块可以是蓝牙模块、WIFI模块、ZigBee模块或IOT模块，IOT模块包括LPWAN模块，例如可以是NBIOT模块、LTE-M模块、Sigfox模块或LoRa模块等此处对于ALD无线通信模块和基站无线通信模块的具体类型不做限定，但需要说明的是ALD的无线通信模块与基站的无线通信模块应为相同类型的无线通信模块，可以进行无线连接。首先，ALD与基站之间需要建立无线通信链路。例如，ALD的无线通信模块与基站的无线通信模块与均为蓝牙模块，则ALD与基站可以根据蓝牙协议建立蓝牙连接。ALD与基站建立无线连接的过程可以按照具体类型的无线通信协议进行，此处不做限定。
302、ALD通过该无线通信链路与基站传输数据；
ALD通过无线通信模块与基站建立无线通信链路后，可以通过该无线通信链路传输数据，可以根据遵循AISG协议规范与ALD通信，例如：RRU可以向ALD发送ALD控制信号后，ALD可以通过该无线通信链路发送确认消息；也可以根据需要由基站厂商和天线厂商协商自定义命令与ALD通信，具体此处不做限定。传输数据的速率范围可以根据该无线通信链路的具体类型和相关协议规定确定，例如，若通过WIFI传输数据，可以根据IEEE 802.11协议的规定进行数据传输，传输速率可达数百兆。
本申请实施例中，由于ALD可以通过新增的无线通信模块与基站建立无线通信链路，并通过该无线通信链路向基站发送数据。相较现有技术中，数据传输需要通过有线线缆，本方 案不需要将线缆连接到ALD和基站的过程，因此，可以避免施工人员连接电缆耗时费力，降低施工难度。
在图2所示的ALD与基站连接方式示意图的基础上，请参阅图4，本申请实施例中ALD与基站连接的方法的另一个实施例示意图。
401、RRU与ALD建立无线通信链路；
本申请实施例中，基站通过RRU与ALD连接，基站的RRU包含无线通信模块，ALD也包含无线通信模块，无线通信模块可以是蓝牙模块、WIFI模块、ZigBee模块或IOT模块，IOT模块包括LPWAN模块，例如可以是NBIOT模块、LTE-M模块、Sigfox模块或LoRa模块等。此处对于无线通信模块的具体类型不做限定，但需要说明的是RRU的无线通信模块与ALD的无线通信模块应为相同类型的无线通信模块，可以进行无线连接。RRU与ALD之间建立无线通信链路。例如，RRU的无线通信模块与ALD的无线通信模块均为WIFI模块，则RRU与ALD可以根据IEEE 802.11协议建立WIFI连接。其他情况下，RRU与ALD建立无线连接的过程可以按照具体类型的无线通信协议进行，此处不做限定。
402、RRU通过该无线通信链路与ALD传输数据；
RRU与ALD通过无线通信模块建立无线通信链路后，可以通过该无线通信链路传输数据，例如RRU可以向ALD发送ALD控制信号。传输数据的速率范围可以根据该无线通信链路的具体类型和相关协议规定确定，例如，若通过WIFI传输数据，可以根据IEEE 802.11协议进行数据传输，传输速率可达数百兆。
本申请实施例提供的ALD与基站连接的方法，由于基站的RRU可以通过新增的无线通信模块与ALD建立无线通信链路，并通过该无线通信链路向ALD发送数据。相较现有技术中，数据传输需要通过有线线缆，本方案不需要将线缆连接到ALD和RRU的过程，因此，可以避免施工人员连接电缆耗时费力，降低施工难度。
下面，请参阅图5，本申请实施例中ALD与基站的连接方式示意图。
本实施例中，存在3个ALD，分别是ALD1、ALD2和ALD3，每个ALD内部均配置了一个ZigBee模块；基站中存在两个RRU需要与ALD进行连接，图中可见RRU1和RRU2，每个RRU均配置了一个外接的ZigBee适配模块，可以是通过AISG-RS485接头连接，此处对于接头类型不做具体限定。其中，RRU1分别与ALD2和ALD3通过ZigBee网络连接，RRU2分别与ALD2和ALD3通过ZigBee网络连接，此外，ALD1与ALD2通过ZigBee网络级联，ALD2与ALD3也通过ZigBee网络连接。
需要说明的是，本实施例中，ALD1与RRU1没有直接相连，而是与ALD2级联，原因可以是人为配置，也可以是由于物理位置的限制，RRU1和ALD1不能收到对方的信号，而ALD2的位置可能恰好与ALD1和RRU1都能连接。
在上述网络架构中，3个ALD与两个RRU可以进行通信，例如传输ALD控制信息；3个ALD之间也可以通过ZigBee网络传输数据，例如传输ALD的位置信息，可以用于确定3个ALD之间的相对位置。
在图5提供的RRU与ALD的ZigBee网络架构基础上，请参阅图6，本申请实施例中RRU与ALD的连接的交互实施例示意图。
由于RRU和ALD均配置了ZigBee无线通信模块，首先需要建立ZigBee网络。ZigBee模 块具有自组网功能，此外，还可以通过基站中央处理器等对组网过程进行控制。在本实施例中，以ALD2的ZigBee模块为网络协调器进行自组网为例进行说明，首先ALD2的ZigBee模块进行网络初始化，包括判断节点附近区域是否存在ZigBee网络，若不存在，则进行信道扫描选择信道号并设置网络ID，等待其他节点加入，成为该ZigBee网络的协调器，负责网络的建立及网络地址的分配。
步骤1、ALD1与ALD2连接，加入ZigBee网络；
ALD1可以通过主动扫描或者是协调器的被动扫描获取网络信息，然后向协调器发送连接请求，通过两个节点相互确认，获取网络内ALD设备类型以及ALD序列号，ALD设备类型可以是TMA或者RET等，ALD序列号为ALD的身份标识(ID)。ALD1可以加入该ZigBee网络，协调器将为ALD1分配网络短地址通过这个地址进行数据的收发，网络拓扑关系和地址会保存在闪存中。
步骤2、ALD3与ALD2连接，加入ZigBee网络；
步骤3、RRU1与ALD2连接，加入ZigBee网络；
步骤4、RRU2与ALD2连接，加入ZigBee网络；
步骤2至步骤4中各节点加入ZigBee网络的过程与步骤1类似，此处不再赘述。
需要说明的是，步骤1至步骤4的执行顺序不做限定。
步骤5、RRU1与ALD3连接；
RRU1可以向ZigBee网络内所有结点发送AISG扫描帧，获取网络内ALD设备类型以及ALD序列号等信息，RRU1可与ALD3相互确认并建立连接，其中ALD3作为ZigBee网络路由器节点，还可以负责转送资料包。
步骤6、RRU2与ALD3连接，连接过程与步骤5类似，此处不再赘述。
需要说明的是，步骤5和步骤6的执行顺序不做限定，可以先执行步骤5再执行步骤6，或者先执行步骤6，再执行步骤5。
通过步骤1至步骤6，本申请实施例中的ZigBee网络拓扑形成，可以进行数据的传输，ZigBee网络中数据传输的速率可以是250千比特每秒(kbit/s)、20kbit/s或40kbit/s等，具体传输速率可以根据使用需求设定，此处不做限定。
由于节点数量较多，下面，以RRU1与ALD1之间的数据传输，和RRU2与ALD3之间的数据传输为例进行说明，请参考步骤7至步骤10，以及步骤11和步骤12。收发消息的各个步骤中，都可以根据需要对消息进行加密和验证，下面不再一一赘述。
步骤7，RRU1向ALD2发送消息；
当RRU1需要向ALD1传递信息，例如对ALD1的控制信息时，虽然RRU1未与ALD1直接相连，但是RRU1可以通过ZigBee网络向ALD2发送消息，并请求ALD2将消息转发给ALD1。
步骤8，ALD2向ALD1发送消息；
ALD2接收到RRU1发送给ALD1的消息后，可以根据网络短地址，将消息转发给ALD1。
步骤9，ALD1向ALD2返回消息；
ALD1接收到ALD2转发的RRU1发送的消息后，将回复确认消息，并将该消息返回给ALD2。
步骤10，ALD2向RRU1返回消息；
ALD2接收到ALD1返回的消息后，可以根据地址标识，将该消息返回给RRU1。
这样，由步骤7至步骤10可以实现ALD1与RRU1之间的数据传输。
步骤11、RRU2向ALD3发送消息；
RRU2可以通过ZigBee网络直接向ALD3发送消息，该消息可以是对ALD3的控制消息。
步骤12、ALD3向RRU2返回消息；
ALD3收到消息后，可以向RRU2返回确认消息。
这样，步骤11和步骤12可以实现ALD3与RRU2之间的数据传输。
本申请实施例提供的RRU与ALD连接的方法，由于RRU与ALD可以通过新增的ZigBee模块建立ZigBee网络，并通过该ZigBee网络传输数据。相较现有技术，数据传输需要通过有线线缆，在本方案中，存在多个ALD和多个RRU的场景下，不仅可以节省多条线缆的成本，还可以避免多条线缆的连接工作，降低施工难度。
下面，请参阅图7，本申请实施例中RRU与ALD的另一个连接方式示意图。
本实施例中，存在3个ALD，分别是ALD1、ALD2和ALD3，每个ALD内部均配置了一个蓝牙模块；还存在两个基站，基站通过RRU与ALD连接，图中可见RRU1和RRU2，RRU1配置了一个外接的蓝牙适配模块，可以是通过AISG-OOK接口连接，此处对于接头类型不做具体限定，RRU2内置了一个蓝牙模块。
其中，RRU1和RRU2分别与ALD2通过蓝牙网络连接，此外，ALD1与ALD2通过蓝牙网络级联，ALD2与ALD3也通过蓝牙网络级联。
在上述网络架构中，ALD2可以与两个RRU进行通信，ALD1和ALD3则通过ALD2与两个RRU通信。
在图7提供的RRU与ALD的蓝牙网络架构基础上，请参阅图8，本申请实施例中RRU与ALD的连接的交互实施例示意图。
由于RRU和ALD均配置了蓝牙无线通信模块，首先需要建立蓝牙网络。根据蓝牙协议，一个主设备可以同时与7个从设备建立连接，在本实施例中，以ALD2为主设备为例进行说明，ALD2作为主设备将主动扫描周围的蓝牙设备，并发起连接，此外，还可以通过自定义协议鉴权，识别其连接的节点是不是用于RRU、ALD传输数据的无线通信模块，如果是则保持连接，如果不是则断开连接。然后，可以对各个蓝牙节点进行节点配置，这一步骤通过配置状态设置各节点的类型，还可以对个节点订阅地址进行保存。这一操作可以由终端，例如具有蓝牙模块的手机或PC进行控制，或者由ALD或基站的中央处理器通过软件进行控制，此处具体不做限定。
步骤1、RRU1与ALD2连接；
RRU1的蓝牙适配模块通过查询ALD2的地址，可以进行寻呼，与ALD2通过蓝牙网络进行连接，此外，还可以通过自定义协议鉴权，识别其连接的节点是不是用于RRU、ALD传输数据的无线通信模块，如果是则保持连接，如果不是则断开连接。在建立蓝牙连接的过程中都可以进行鉴权步骤，本申请实施例中将不再赘述。
步骤2、ALD3与ALD2连接；
步骤3、ALD1与ALD2连接；
步骤4、RRU2与ALD2连接；
步骤2至步骤4进行蓝牙连接的过程与步骤1类似，此处不再赘述。
需要说明的是，步骤1至步骤4的执行顺序不做限定。
通过步骤1至步骤4，本实施例中的3个ALD和2个RRU实现了蓝牙组网，可以进行数据传输，由于节点数量较多，下面，以RRU1与ALD2之间的数据传输，和RRU2与ALD1之间的数据传输为例进行说明，请参考步骤5和步骤6，以及步骤7至步骤10。
步骤5、RRU1向ALD2发送消息；
当RRU1需要向ALD2发送控制信号时，可以通过外接的蓝牙适配模块向ALD2发送消息，消息传输的速率可以根据蓝牙协议确定，例如可以是1兆位每秒(million bits per second，Mbps)。
步骤6、ALD2向RRU1返回消息；
ALD2接收到RRU1发送的消息后，可以通过ALD2内置的蓝牙模块向RRU1返回消息。
这样，步骤5和步骤6可以实现ALD2与RRU1之间的数据传输。
步骤7、RRU2向ALD2发送消息；
当RRU2需要向ALD1发送ALD1的控制信号时，虽然RRU1与ALD1并未直接建立蓝牙连接，但可以通过ALD2进行路由转发。RRU2向ALD2发送消息，消息中携带了ALD1的地址信息。
步骤8、ALD2向ALD1发送消息；
ALD2接收到RRU2向ALD1发送的消息后，可以对消息进行转发，即将接收的消息发送给ALD1。
步骤9、ALD1向ALD2返回消息；
ALD1接收到ALD2转发的RRU2发送的信息后，可以根据控制信号进行相应操作，并返回确认消息，同样地，该消息需要经ALD2转发，因此，ALD1向ALD2返回消息，该消息中携带RRU2的地址信息。
步骤10、ALD2向RRU2返回消息；
ALD接收ALD1发送的返回消息后，将该消息转发给RRU2。
这样，步骤7至步骤10可以实现ALD1与RRU2之间的数据传输。
本申请实施例提供的RRU与ALD连接的方法，由于RRU与ALD可以通过新增的蓝牙模块或蓝牙适配模块建立蓝牙网络，并通过该蓝牙网络传输数据。相较现有技术，数据传输需要通过有线线缆，在本方案中，存在多个ALD和多个RRU的场景下，不仅可以节省多条线缆的成本，还可以避免多条线缆的连接工作，降低施工难度。
上面对ALD与基站的连接方法进行了介绍，下面将介绍实现该方法的ALD和基站。
