ALD controller可以是基站， 调试工具、 分组控制单元 （Packet Control Unit, PCU )等， 以上列举的作为 ALD controller的设备仅为示例性说明， 本发明并不限定于此， 其他能够进行 ALD控制的设备均落入本发明的保护 范围内。
图 1示出了根据本发明发现 ALD的方法 100的示意性流程图。 如图 1 所示， 该方法 100包括：
S110, ALD controller向 ALD发送上报命令， 该上 4艮命令用于指示该 ALD向天馈控制设备 ALD controller上报唯一标识码 Unique ID; SI 20,该 ALD controller接收和记录该 ALD上艮的 Unique ID,该 Unique
ID 由该 ALD 根据冲突检测和冲突退避的发送机制通过高级数据链路控制 HDLC总线发送。
在本发明实施例中，通过向 ALD发送上报命令， ALD收到上报命令后， 由 ALD向 ALD controller上报 Unique ID， 相比通过按位扫描的方式， 节省 了发现 ALD的时间， 可用极快的速度获取 ALD的 Unique ID; 并且不会因 为 ALD之间的 Unique ID差异性低而增加漏扫情况发生的概率。
在 S110中， ALD controller 向 ALD发送上报命令， ALD数量为多个， ALD controller与该多个 ALD通过总线连接， 每个 ALD可有两个串口， A 串口和 B串口， A串口和 B串口和高级数据链路控制（High Level Data Link Control, HDLC)总线连接， 其中 A串口用于和 HDLC总线进行通信， B串 口用于 HDLC总线上的冲突侦听检测。
ALD controller通过 HDLC总线与每个 ALD进通信， 该通信包括 ALD controller 向各 ALD 设备发送各种命令或消息， 以及接收各 ALD发送的 Unique ID信息。
ALD controller的通信地址为固定， 且该地址为所有 ALD所知。
ALD controller以广播的方式在 HDLC总线上发送上报命令，通知 HDLC 总线上的所有 ALD开始上报 Unique ID。
各 ALD接收到该上报命令后， 向 ALD controller上报 Unique ID。 该 Unique ID为 ALD设备的全球唯一标识码， 又称之为序列号； ALD进行上 报时， 每秒可完成上报的 ALD数量是有限和确定的， 该上报时间的长短可 根据 ALD的数量来确定。
在 S 120中，该 ALD controller接收和记录该 ALD上报的 Unique ID,该 Unique ID由该 ALD根据冲突检测和冲突退让的发送机制通过高级数据链路 控制 HDLC总线发送。
具体的， 该冲突检测退让机制为： ALD的两个串口， A 串口用于正常的 485通讯， B串口用于观察检测 HDLC总线上的数据是否产生冲突,在 HDLC 总线上， 有多于一个 ALD上报 Unique ID , 即视为产生了沖突,一旦 Β串口 检测到冲突产生， 则立即停止发送， 随机延时一段时间后再次发送， 再次发 送时更新地址， 直到发送成功为止。
该冲突检测机制以及冲突后的退让机制， 使得可以在更短的时间内完成 上报 Unique ID， 减少冲突的发生。
可选的， ALD收到上报命令后向 ALD controller上报 Unique ID后， 进 行分配地址：
起始地址为 ALD controller默认认地址加 1 ,首次成功上报 Unique ID的 ALD的地址为起始地址；
下次成功上报 Unique ID的 ALD的地址为上次成功上报 Unique ID的 ALD的地址加 1。
该默认地址为 ALD control的地址。 具体的， 当前未上 4艮 Unique ID的 ALD, 观察 HDLC 总线， 在未检测到冲突的情况下， 有 ALD 成功上报了 Unique ID时， 记录此 Unique ID对应的地址， 下次抢到发送机会时， 自身的 地址为此地址加 1。

( 2 ) ALD Controller 接收到的 ALDUnique ID 数量大于等于 ALD Controller支持的最大数量。
以上条件任意一条满足， 即认为满足退出条件， ALD controller退出观 察状态。
可选的， 当上报时间未到但满足退出条件， ALD controller退出该观察 状态， 意味着所有 ALD都已经完成了 Unique ID上^ =艮和对应的通信地址协 商， 在此情况下， ALD Controller检查是否存在地址冲突， 如果存在地址冲 突， 则在 HDLC总线上广播命令通知地址冲突的 ALD更新地址， 地址冲突 的 ALD的接收器 610接收到地址更新命令后， 处理器 630根据命令中携带 的信息判断自己的地址是否需要更新， 如果需要更新， 则处理器 630更新为 ALD Controller指定的地址 ， 否则不更新。 此过程完成后， 流程终止。
在本发明实施例中， ALD接收到 ALD controller发送的上报命令后， 由 ALD向 ALD controller上报 Unique ID, 相比通过按位扫描的方式， 节省了 扫描时间， 可用极快的速度获取所有 ALD的 Unique ID, 并且减少了漏扫情 况的发生， 此外， 在 ALD的扫描过程中， 同时完成了各 ALD的通信地址分 配， 免去了在扫描完成后专门分配地址的过程， 减少了 ALD Controller与 ALD间的交互消息， 使得 ALD Controller可以更快速的完成 ALD配置。 应理解， 在本发明的各种实施例中， 上述各过程的序号的大小并不意味 着执行顺序的先后， 各过程的执行顺序应以其功能和内在逻辑确定， 而不应 对本发明实施例的实施过程构成任何限定。
