附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的技术方案，可以应用于各种通信系统，例如：GSM，码分多址(CDMA，Code Division Multiple Access)系统，宽带码分多址(WCDMA，Wideband Code Division Multiple Access Wireless)，通用分组无线业务(GPRS，General Packet Radio Service)，长期演进(LTE，Long Term Evolution)等。
基站，可以是GSM或CDMA中的基站(BTS，Base Transceiver Station)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(eNB或e-NodeB，evolutional Node B)，本发明并不限定，但为描述方便，下述实施例以Node B为例进行说明。
在现有技术中，REC与RE通过CPRI通信线路级联的方式进行连接，即如图1所示的连接方式，在这种方式下，一旦任一节点通信故障，则可以 导致REC与此故障点之后的任一RE无法通信。由此，本发明实施例提供了一种基站、REC、RE以及信息传输方法，为了便于理解，以下将结合图2至图16进行详细说明。
图2是根据本发明实施例中的基站100的示意性框图。如图2所示，该基站100包括REC110与至少一个RE120(图2中以RE为4个为例，当并不限于此)；其中，
REC110与至少一个RE120中的每一个RE120通过主线路进行通信；
在REC110与至少一个RE120中的任一RE120进行通信的主线路故障时，REC110确定与主线路故障的该任一RE120进行通信的备用线路；
REC110通过备用线路与该主线路故障的任一RE120进行通信。
因此，在本发明实施例中，在REC确定与任一RE的通信的主线路故障时，可以确定与该主线路故障的RE进行通信的备用线路，并通过备用线路与该主线路故障的RE进行通信，由此在主线路故障时不需要人工下站处理，减少了维护成本，并降低了业务中断时间，从而提升用户体验。
应理解，虽然图1中，REC110与各个RE120直接相连，这只是示意性说明REC110与RE120可以通信；并不意味着REC110与RE120必须直接相连，例如，REC110可以通过一个RE120与另一个RE120相连。
在本发明实施例中，REC还可以称作为基带处理单元(Base Band Unit，BBU)，RE还可以称作为射频拉远单元(Radio Remote Unit，RRU)。
在本发明实施例中，主线路可以是CPRI通信线路；备用线路可以是电力线线路，或者为电力线加CPRI通信线路。当然，主线路可以是电力线线路或为电力线加CPRI通信线路，备用线路为CPRI通信线路，或者为其他方式，具体可以根据应用场景而定，本发明实施例并不对此进行限定。但是本发明实施例以主线路为CPRI通信线路，备用线路为电力线线路或者为电力线加CPRI通信线路为主进行说明。
由于REC和RE天然具有电力线网络供电，本发明实施例在REC与RE的CPRI通信线路出现故障时，借用REC和RE的电力线网络实现REC与RE的通信。
在本发明实施例中，CPRI通信线路是指支持CPRI协议的线路；CPRI通信线路可以包括光纤、同轴电缆和以太网线中的至少一种。
在本发明实施例中，REC通过备用线路与该主线路故障的任一RE进行 通信，可以包括：
REC通过备用线路对主线路故障的RE进行复位或升级以恢复该主线路故障的RE的主线路。
例如，在某一RE的主线路故障的原因是该RE的光口参数不合适，则可以通过备用线路发送指示信息修改该RE的光口参数，由此可以恢复主线路。
再例如，RE的硬件发生问题，导致RE无法正常启动，需要进行一下上下电才能恢复，因为此时RE已经出现问题，所以无法通过CPRI通信线路再与其成功通信。则REC可以确定备用线路，该备用线路可以包括电力线，REC可以通过备用线路向RE发指示信息，指示RE进行上下电。
在本发明实施例中，REC可以实时(例如，周期性或者初始化阶段等)扫描控制的所有RE，并确定所有RE中主线路故障的RE，并确定主线路故障的RE的备用线路；REC也可以通过与某一RE互发心跳消息确定与该RE进行通信的主线路故障之后，确定与该RE进行通信的备用线路。为了便于理解，以下将分别结合实施例A和实施例B对这两种情况进行详细说明。
实施例A
在该种实施例下，REC可以实时扫描控制的所有RE，并确定所有RE中主线路故障的RE，并确定主线路故障的RE的备用线路。
可选地，REC通过CPRI端口或通过电力线端口和CPRI端口，发送针对控制的所有RE的寻址请求消息；每一个RE在通过第一端口接收到寻址请求消息后，通过第一端口发送寻址响应消息，第一端口为上联CPRI端口或电力线端口；REC根据每一个RE发送的寻址响应消息的路径是否包括主线路，确定主线路故障的RE；REC根据主线路故障的RE发送的至少一条寻址响应消息的路径，确定与主线路故障的RE进行通信的备用线路。
可选地，在每一个RE在接收到寻址请求消息后，在第一端口为上联CPRI端口时，通过下联CPRI端口和电力线端口转发寻址请求消息。
在本发明实施例中，RE的CPRI端口包括上联CPRI端口和下联CPRI端口，其中，上联CPRI端口是指靠近REC的CPRI端口，下联CPRI端口是指远离REC的CPRI端口，具体可参考见图3中的标识，该解释适用于本发明的所有实施例。
可选地，REC中的每一个RE通过下联CPRI端口或通过电力线端口接收到其他RE发送的寻址响应消息时，通过上联CPRI端口转发其他RE发送的寻址响应消息。
可选地，在每一个RE在通过下联CPRI端口和电力线端口转发寻址请求消息时，将转发路径信息携带在寻址请求消息中，以便寻址请求消息对应的寻址响应消息按照寻址请求消息的反向路径返回至REC。
可选地，所有RE中存在与REC属于相同电力线网络的RE时，REC通过CPRI端口和电力线端口，发送针对所有RE的寻址请求消息；在所有REC中不存在与REC属于相同电力线网络的RE时，REC通过CPRI端口或通过CPRI端口和电力线端口，发送针对所有RE的寻址请求消息。
可选地，REC将首次收到的来自主线路故障的RE的寻址响应消息的路径确定为与主线路故障的RE进行通信的备用线路。
为了便于理解，以下结合图3至图5对于实施例A中如何确定主线路故障的RE，并确定与主线路故障的RE进行通信的备用线路进行详细说明。
在图3中，REC、RE1、RE2、RE3、RE4和RE5属于同一个电力线网络；并假设RE4至RE5的CPRI通信线路故障，例如RE5的硬件故障或RE5的光口参数不合适导致的RE4至RE5的CPRI通信线路故障。
REC通过电力线端口和CPRI端口发送寻址请求消息，该寻址请求消息针对所有的RE。REC发送的寻址请求消息可以通过CPRI通信线路到达RE1，并通过电力线分别到达RE1、RE2、RE3、RE4和RE5。
对于各个RE，寻址请求消息的处理可以满足以下原则：若在上联CPRI端口收到寻址请求消息，则通过电力线端口和下联CPRI端口转发，并向上联CPRI端口回寻址响应消息；若在电力线端口收到寻址请求消息，则在电力线端口回寻址响应响应消息，不再转发。
例如，对于RE1而言，通过上联CPRI端口接收到寻址请求消息，则可以通过上联CPRI端口向REC回寻址响应消息，并通过下联CPRI端口和电力线端口转发寻址请求消息；通过电力线端口收到寻址请求消息，则可以通过电力线端口发送寻址响应消息，但不进行转发。
例如，对于RE2而言，通过上联CPRI端口接收到经RE1转发的寻址请求消息，则可以通过上联CPRI端口向REC回寻址响应消息，并通过下联 CPRI端口和电力线端口转发寻址请求消息；通过电力线端口收到寻址请求消息，则可以通过电力线端口向REC回寻址响应消息，而不进行转发。
例如，对于RE3而言，通过上联CPRI端口收到经RE2转发的寻址请求消息，则可以通过上联CPRI端口回寻址响应消息，并通过下联CPRI端口和电力线端口转发寻址请求消息；通过电力线端口收到寻址请求消息，则可以通过电力线端口向REC回寻址响应消息，而不进行转发。
例如，对于RE4而言，通过上联CPRI端口接收经RE3转发的寻址请求消息，则可以通过上联CPRI端口向REC回寻址响应消息，并通过下联CPRI端口和电力线端口转发寻址请求消息；通过电力线端口收到寻址请求消息，则可以通过电力线端口向REC回寻址响应消息，而不进行转发。
例如，对于RE5而言，因为RE4和RE5之间的CPRI线路故障，则RE5只通过电力线端口收到直接来自REC的以及经RE1、RE2、RE3和RE4通过电力线转发的寻址请求消息，并分别通过电力线端口分别发送针对各个寻址请求消息的寻址响应消息。
而对于寻址响应消息的返回路径，可以按照以下两种方式实现：
在第一种方式中，各个RE在转发寻址请求消息时，可以将寻址请求消息在自身的转发路径信息(例如，接收端口和发送端口的信息)携带在该寻址请求消息中，由此寻址请求消息可以携带各个转发节点处的转发路径信息。在RE在针对寻址请求消息发送寻址响应消息时，可以将寻址请求消息中的转发路径信息携带在寻址响应消息中，以便该寻址响应消息按照对应的寻址请求消息的反向路径返回至REC。
第二种方式中，对于各个RE，在电力线端口或下联CPRI端口收到寻址响应消息，向上联CPRI端口转发寻址响应消息。
例如，RE4在电力线端口收到RE5的寻址响应消息后，则可以将该寻址响应消息封装为CPRI协议的消息，并通过上联CPRI端口转发该寻址响应消息，该寻址响应消息经过RE3、RE2和RE1的透传到达REC；RE3在电力线端口收到RE5的寻址响应消息后，则可以将该寻址响应消息封装为CPRI协议的消息，并通过上联CPRI端口转发该寻址响应消息，该寻址响应消息经过RE2和RE1的透传到达REC；RE1和RE2通过电力线端口收到RE5寻址响应消息所做的处理与RE3和RE4类似；REC也可以收到未经任何RE转发的来自RE5的寻址响应消息。REC在收到各个RE转发的寻址响 应消息，确定寻址响应消息的路径不包括主线路，则判断与RE5通信的主线路故障，则可以从各个RE转发的寻址响应消息中的路径中，选择与RE5进行通信的备用线路；例如，将首次收到的来自RE5的响应消息的路径确定为备用线路，例如，该首次收到的寻址响应消息为在RE4处进行CPRI协议封装处理的消息，则REC通过该首次收到的寻址响应消息中封装的RE4的信息，确定与RE5进行通信的备用线路的路径为通过CPRI线路到达RE4，再由RE4通过电力线发送到RE5。
例如，RE3在电力线端口和下联CPRI端口收到RE4的寻址响应消息之后，并通过上联CPRI端口分别转发该寻址响应消息，并通过RE2和RE1的透传到达REC；REC确定RE4的寻址响应消息的中包括通过主线路到达REC的响应消息，则确定与RE4通信的主线路未故障，并通过主线路该RE4正常通信。其中，对于RE2、RE3和RE1主线路是否故障的判断与RE4类似，在此不再赘述。
在图4中，RE1、RE2、RE3、RE4和RE5属于同一个电力线网络，而REC属于另一个电力线网络；并假设RE4至RE5的CPRI通信线路故障，例如RE5的硬件故障或RE5的光口参数不合适导致的RE4至RE5的CPRI通信线路故障。
REC通过CPRI端口或通过电力线端口和CPRI端口发送寻址请求消息，该寻址请求消息针对所有的RE。在图4中，由于不存在与REC属于相同电力线网络的RE，则REC可以只通过CPRI端口发送寻址请求消息。可选地，REC可以不对是否存在与自身属于相同电力线网络的RE进行判断，直接根据其所属的CPRI端口和电力线端口发送寻址请求消息。REC发送的寻址请求消息可以通过CPRI端口到达RE1。
对于各个RE，寻址请求消息的处理可以满足以下原则：若在上联CPRI端口收到寻址请求消息，则向电力线端口和下联CPRI端口转发，并向上联CPRI端口回寻址响应消息；若在电力线端口收到寻址请求消息，则在电力线端口回寻址响应响应消息，不再转发。
例如，对于RE1而言，通过上联CPRI端口接收到寻址请求消息，则可以通过上联CPRI端口向REC回寻址响应消息，并通过下联CPRI端口和电力线端口转发寻址请求消息。
例如，对于RE2而言，通过上联CPRI端口接收到经RE1转发的寻址请求消息，则可以通过上联CPRI端口向REC回寻址响应消息，并通过下联CPRI端口和电力线端口转发寻址请求消息；通过电力线端口收到寻址请求消息，则可以通过电力线端口向REC回寻址响应消息，而不进行转发。
例如，对于RE3而言，通过上联CPRI端口收到经RE2转发的寻址请求消息，则可以通过上联CPRI端口回寻址响应消息，并通过下联CPRI端口和电力线端口转发寻址请求消息；通过电力线端口收到寻址请求消息，则可以通过电力线端口向REC回寻址响应消息，而不进行转发。
例如，对于RE4而言，通过上联CPRI端口接收经RE3转发的寻址请求消息，则可以通过上联CPRI端口向REC回寻址响应消息，并通过下联CPRI端口和电力线端口转发寻址请求消息；通过电力线端口收到寻址请求消息，则可以通过电力线端口向REC回寻址响应消息，而不进行转发。
例如，对于RE5而言，RE5通过电力线端口收到经RE1、RE2、RE3和RE4通过电力线转发的寻址请求消息，并分别通过电力线端口分别发送针对各个RE转发的寻址请求消息的寻址响应消息；因为RE4和RE5之间的CPRI线路故障，则RE5无法收到RE4通过下联转发的寻址请求消息。
而对于寻址响应消息的返回路径，可以按照以下两种方式实现：
在第一种方式中，各个RE在转发寻址请求消息时，可以将寻址请求消息在自身的转发路径信息(例如，接收端口和发送端口的信息)携带在该寻址请求消息中，由此寻址请求消息可以携带各个转发节点处的转发路径信息。在RE在针对寻址请求消息发送寻址响应消息时，可以将寻址请求消息中的转发路径信息携带在寻址响应消息中，以便该寻址响应消息按照对应的寻址请求消息的反向路径返回至REC。
第二种方式中，对于各个RE，在电力线端口或下联CPRI端口收到寻址响应消息后，向上联CPRI端口转发寻址响应消息。
例如，RE4在电力线端口收到RE5的寻址响应消息后，则可以将该寻址请求消息封装为CPRI协议的消息，并通过上联CPRI端口转发该寻址响应消息，该寻址响应消息经过RE3、RE2和RE1的透传到达REC；RE3在电力线端口收到RE5的寻址响应消息后，则可以将该寻址请求消息封装为CPRI协议的消息，并通过上联CPRI端口转发该寻址响应消息，该寻址响应消息经过RE2和RE1的透传到达REC；RE1和RE2通过电力线端口收到 RE5寻址响应消息所做的处理与RE3和RE4类似。REC在收到各个RE转发的来自RE5寻址响应消息后，确定寻址响应消息的路径不包括主线路，则判断与RE5通信的主线路故障，并可以从各个RE转发的寻址响应消息中的路径中，选择与RE5进行通信的备用线路；例如，将首次收到的来自RE5的响应消息的路径确定为备用线路，例如，该首次收到的寻址响应消息为在RE4处进行CPRI协议封装处理的消息，则REC通过该首次收到的寻址响应消息中封装的RE1的信息，确定与RE5进行通信的备用线路的路径为待发消息通过CPRI线路到达RE4，再由RE4通过电力线发送到RE5。
例如，RE3在电力线端口和下联CPRI端口收到RE4的寻址响应消息之后，并通过上联CPRI端口分别转发来自电力线端口和下联CPRI端口的寻址响应消息，并通过RE2和RE1的透传到达REC；RE2和RE1收到RE4的寻址响应消息处理类似；REC确定RE4的寻址响应消息的中包括通过主线路到达REC的响应消息，则确定与RE4通信的主线路未故障，并通过主线路与该RE正常通信。其中，对于RE2、RE3和RE1主线路是否故障的判断与RE4类似，在此不再赘述。
在图5中，REC与RE1和RE2属于同一电力线网络，RE3、RE4和RE5属于另外一个电力线网络；并假设RE4至RE5的CPRI通信线路故障，例如RE5的硬件故障或RE5的光口参数不合适导致的RE4至RE5的CPRI通信线路故障。
REC通过电力线端口和CPRI端口发送寻址请求消息，该寻址请求消息针对所有的RE。在图5中，由于REC存在与REC属于相同电力线网络的RE，即RE1和RE2，则REC需通过电力线端口和CPRI端口发送寻址请求消息。可选地，REC可以不对是否存在与自身属于相同电力线网络的RE进行判断，直接根据其所属的CPRI端口和电力线端口发送寻址请求消息。REC发送的寻址请求消息可以通过电力线直接到达RE1和RE2，并通过CPRI通信线路到达RE1。
对于各个RE，寻址请求消息的处理可以满足以下原则：若在上联CPRI端口收到寻址请求消息，则向电力线端口和下联CPRI端口转发，并向上联CPRI端口回寻址响应消息；若在电力线端口收到寻址请求消息，则在电力线端口回寻址响应响应消息，不再转发。
例如，对于RE1而言，通过上联CPRI端口接收到寻址请求消息，则可以通过上联CPRI端口向REC回寻址响应消息，并通过下联CPRI端口和电力线端口转发寻址请求消息；通过电力线端口收到寻址请求消息，则可以通过电力线端口向REC回寻址响应消息，而不进行转发。
例如，对于RE2而言，通过上联CPRI端口接收到经RE1转发的寻址请求消息，则可以通过上联CPRI端口向REC回寻址响应消息，并通过下联CPRI端口和电力线端口转发寻址请求消息；通过电力线端口收到寻址请求消息，则可以通过电力线端口向REC回寻址响应消息，而不进行转发。
例如，对于RE3而言，通过上联CPRI端口收到经RE2转发的寻址请求消息，则可以通过上联CPRI端口回寻址响应消息，并通过下联CPRI端口和电力线端口转发寻址请求消息。
例如，对于RE4而言，通过上联CPRI端口接收经RE3转发的寻址请求消息，则可以通过上联CPRI端口向REC回寻址响应消息，并通过下联CPRI端口和电力线端口转发寻址请求消息，通过电力线端口收到寻址请求消息，则可以通过电力线端口向REC回寻址响应消息，而不进行转发。
例如，对于RE5而言，RE5通过电力线端口收到经RE3和RE4通过电力线转发的寻址请求消息，分别通过电力线端口发送针对各个寻址请求消息的寻址响应消息；因为RE4和RE5之间的CPRI线路故障，则RE5无法收到RE4通过下联CPRI端口转发的寻址请求消息。
而对于寻址响应消息的返回路径，可以按照以下两种方式实现：
在第一种方式中，各个RE在转发寻址请求消息时，可以将寻址请求消息在自身的转发路径信息(例如，接收端口和发送端口的信息)携带在该寻址请求消息，由此寻址请求消息可以携带各个转发节点处的转发路径信息。在RE在针对寻址请求消息发送寻址响应消息时，可以将寻址请求消息中的转发路径信息携带在寻址响应消息中，以便该寻址响应消息按照对应的寻址请求消息的反向路径返回至REC。
第二种方式中，对于各个RE，在电力线端口或下联CPRI端口收到寻址响应消息，向上联CPRI端口转发寻址响应消息。
例如，RE4在电力线端口收到RE5的寻址响应消息后，则可以将该寻址请求消息封装为CPRI协议的消息，并通过上联CPRI端口转发该寻址响应消息，该寻址响应消息经过RE3、RE2和RE1的透传到达REC；RE3在 电力线端口收到RE5的寻址响应消息后，则可以将该寻址响应消息封装为CPRI协议的消息，并通过上联CPRI端口转发该寻址响应消息，该寻址响应消息经过RE2和RE1的透传到达REC。REC在收到多条寻址响应消息后，确定多条寻址响应消息的路径不包括主线路，则判断与RE5通信的主线路故障，则可以从该多条寻址响应消息中的路径中，选择与RE5进行通信的备用线路；例如，将首次收到的来自RE5的响应消息的路径确定为备用线路，例如，该首次收到的寻址响应消息为在RE3处进行CPRI协议封装处理的消息，则REC通过该首次收到的寻址响应消息中封装的RE3的信息，则确定与RE5进行通信的备用线路的路径为待发消息通过CPRI线路经由RE1和RE2的透传到达RE3，再由RE3通过电力线发送到RE5。
例如，RE3在电力线端口和下联CPRI端口收到RE4的寻址响应消息之后，并通过上联CPRI端口分别转发该寻址响应消息，并通过RE2和RE1的透传到达REC；REC确定RE4的寻址响应消息的中包括通过主线路到达REC的响应消息，则确定与RE4通信的主线路未故障，并通过主线路与该RE正常通信。其中，对于RE2、RE3和RE1主线路是否故障的判断与RE4类似，在此不再赘述。
因此，在本发明实施例中，REC可以针对所有RE发送寻址请求消息，根据各个RE回复的寻址响应消息的路径判断主线路故障的RE，并确定与该主线路故障的RE进行通信的备用线路，并利用备用线路与该主线路故障的RE进行通信，由此在主线路故障时不需要人工下站处理，减少了维护成本，并降低了业务中断时间，从而提升用户体验。
实施例B
在该种实施例下，REC可以通过和RE之间的心跳判断REC与RE进行通信的主线路是否故障。具体地，REC和RE之间通过主线路相互发心跳消息，如果REC连续预定次数没有收到RE发送的心跳消息，则确定REC与RE进行通信的主线路故障。
可选地，REC在确定与第一RE进行通信的主线路故障时，REC通过电力线端口和CPRI端口中的至少一个发送针对第一RE的寻址请求消息；
可选地，第一RE通过第一端口接收寻址请求消息，通过第一端口发送寻址响应消息，第一端口为上联CPRI端口或电力线端口；
REC根据第一RE发送的至少一个寻址响应消息的路径，确定与第一RE进行通信的备用线路。
可选地，在第一RE通过第一端口接收寻址请求消息之前，第一RE的上游RE通过上联CPRI端口接收到寻址请求消息时，通过下联CPRI端口和电力线端口转发寻址请求消息。
可选地，在第一RE的上游RE通过下联CPRI端口和电力线端口转发寻址请求消息之前，将上游RE处的转发路径消息承载在寻址请求消息中；第一RE在通过第一端口发送寻址响应消息之前，将转发路径消息承载在寻址响应消息中；第一RE的上游RE在接收到寻址响应消息之后，按照寻址响应消息中的转发路径消息转发寻址响应消息，以便寻址响应消息按照对应的寻址请求消息的反向路径返回至REC。
可选地，第一RE的上游RE通过下联CPRI端口或电力线端口接收寻址响应消息，并通过上联CPRI端口转发寻址响应消息。
可选地，第一RE的上游RE在通过电力线端口接收到寻址请求消息时，丢弃寻址请求消息。
可选地，在REC与第一RE属于同一电力线网络时，REC通过电力线端口或通过CPRI端口和电力线端口，发送针对第一RE的寻址请求消息；
在REC与第一RE不属于同一电力线网络时，REC通过CPRI端口或通过CPRI端口和电力线端口，发送针对第一RE的寻址请求消息。
为了便于理解，以下结合图3至图5对于实施例B中如何确定与主线路故障的RE进行通信的备用线路进行详细说明。
在图3中，REC、RE1、RE2、RE3、RE4和RE5属于同一个电力线网络；并假设RE4至RE5的CPRI通信线路故障，例如RE5的硬件故障或RE5的光口参数不合适导致的RE4至RE5的CPRI通信线路故障。在判断与RE5进行通信的主线路故障之后，REC通过电力线端口和CPRI端口发送针对RE5的寻址请求消息。
REC发送的针对RE5的寻址请求消息，可以携带RE5的标识信息。该标识信息可以为该RE5在电力线网络中的地址信息，例如，该RE5在电力线网络中的MAC地址或IP地址。
REC发送的寻址请求消息可以通过电力线直接到达RE1、RE2、RE3、RE4和RE5，并通过CPRI通信线路到达RE1。
对于各个非目标RE，寻址请求消息的处理可以满足以下原则：若在上联CPRI端口收到寻址请求消息，则向电力线端口和下联CPRI端口转发；若在电力线端口收到寻址请求消息，则丢弃该寻址请求消息。
对于目标RE，寻址请求消息的处理可以满足以下原则：在电力线端口收到寻址请求消息，在电力线端口回寻址响应消息。
例如，对于RE1而言，通过上联CPRI端口接收到寻址请求消息，则可以通过下联CPRI端口和电力线端口转发寻址请求消息；通过电力线端口收到寻址请求消息，则可以丢弃该寻址请求消息。
例如，对于RE2而言，通过上联CPRI端口接收到经RE1转发的寻址请求消息，则可以通过下联CPRI端口和电力线端口转发寻址请求消息；通过电力线端口收到寻址请求消息，则可以丢弃该寻址请求消息。
例如，对于RE3而言，通过上联CPRI端口收到经RE2转发的寻址请求消息，则可以通过下联CPRI端口和电力线端口转发寻址请求消息；通过电力线端口收到寻址请求消息，则可以丢弃该寻址请求消息。
例如，对于RE4而言，通过上联CPRI端口接收经RE3转发的寻址请求消息，通过下联CPRI端口和电力线端口转发寻址请求消息，通过电力线端口收到寻址请求消息，则可以丢弃该寻址请求消息。
例如，对于RE5而言，RE5通过电力线端口收到直接来自REC以及经RE1、RE2、RE3和RE4通过电力线转发的寻址请求消息，并分别通过电力线端口发送各个路径的寻址请求消息对应的寻址响应消息。因为RE4至RE5的CPRI线路故障，则RE4通过下联CPRI端口发送的寻址请求消息无法到达RE5。
对于寻址响应消息的返回路径，可以按照以下两种方式实现：
在第一种方式中，各个RE在转发寻址请求消息时，可以将寻址请求消息在自身的转发路径信息(例如，接收端口和发送端口的信息)携带在该寻址请求消息中，由此寻址请求消息可以携带各个转发节点处的转发路径信息。在目标RE在针对寻址请求消息发送寻址响应消息时，可以将寻址请求消息中的转发路径信息携带在寻址响应消息中，以便该寻址响应消息按照对应的寻址请求消息的反向路径返回至REC。
第二种方式中，对于各个RE，在电力线端口或下联CPRI端口收到寻址响应消息，向上联CPRI端口转发寻址响应消息。
例如，RE4在电力线端口收到RE5的寻址响应消息后，则可以将该寻址请求消息封装为CPRI协议的消息，并通过上联CPRI端口转发该寻址响应消息，该寻址响应消息经过RE3、RE2和RE1的透传到达REC；RE3在电力线端口收到RE5的寻址响应消息后，则可以将该寻址请求消息封装为CPRI协议的消息，并通过上联CPRI端口转发该寻址响应消息，该寻址响应消息经过RE2和RE1的透传到达REC。RE2和RE1通过电力线收到RE5的寻址响应消息的处理与RE1和RE2类似。REC可以从多条寻址响应消息的路径中，选择与RE5进行通信的备用线路；例如，将首次收到的来自RE5的响应消息的路径确定为备用线路，例如，该首次收到的寻址响应消息为在RE3处进行CPRI协议封装处理的消息，则REC通过该首次收到的寻址响应消息中封装的RE3的信息，则确定与RE5进行通信的备用线路的路径为待发消息通过CPRI线路经由RE1和RE2的透传到达RE3，再由RE3通过电力线发送到RE5。
在图4中，RE1、RE2、RE3、RE4和RE5属于同一个电力线网络，而REC属于另一个电力线网络；并假设RE4至RE5的CPRI通信线路故障，例如RE5的硬件故障或RE5的光口参数不合适导致的RE4至RE5的CPRI通信线路故障。在判断与RE5进行通信的主线路故障之后，REC通过电力线端口和CPRI端口发送针对RE5寻址请求消息。在图4中，由于REC与RE5不属于相同的电力线网络，则REC可通过电力线端口和CPRI端口，或通过CPRI端口发送寻址请求消息。可选地，REC可以不对是否与RE5属于相同的电力线网络进行判断，直接根据其所属的CPRI端口和电力线端口发送寻址请求消息。REC发送的寻址请求消息可以通过电力线直接到达RE1和RE2，并通过CPRI通信线路到达RE1。
对于各个非目标RE，寻址请求消息的处理可以满足以下原则：若在上联CPRI端口收到寻址请求消息，则向电力线端口和下联CPRI端口转发；若在电力线端口收到寻址请求消息，则丢弃该寻址请求消息。
对于目标RE，寻址请求消息的处理可以满足以下原则：在电力线端口收到寻址请求消息，在电力线端口回寻址响应消息。
例如，对于RE1而言，通过上联CPRI端口接收到寻址请求消息，则可以通过下联CPRI端口和电力线端口转发寻址请求消息；通过电力线端口收到寻址请求消息，则可以丢弃该寻址请求消息。
例如，对于RE2而言，通过上联CPRI端口接收到经RE1转发的寻址请求消息，则可以通过下联CPRI端口和电力线端口转发寻址请求消息；通过电力线端口收到寻址请求消息，则可以丢弃该寻址请求消息。
例如，对于RE3而言，通过上联CPRI端口收到经RE2转发的寻址请求消息，则可以通过下联CPRI端口和电力线端口转发寻址请求消息；通过电力线端口收到寻址请求消息，则可以丢弃该寻址请求消息。
例如，对于RE4而言，通过上联CPRI端口接收经RE3转发的寻址请求消息，通过下联CPRI端口和电力线端口转发寻址请求消息；通过电力线端口收到寻址请求消息，则可以丢弃该寻址请求消息。
例如，对于RE5而言，RE5通过电力线端口收到各个RE通过电力线转发的寻址请求消息，并分别通过电力线端口发送各个RE转发的寻址请求消息对应的寻址响应消息。因为RE4至RE5的CPRI线路故障，则RE5无法收到RE4通过下联CPRI端口转发的寻址请求消息。
而对于寻址响应消息的返回路径，可以按照以下两种方式实现：
在第一种方式中，各个RE在转发寻址请求消息时，可以将寻址请求消息在自身的转发路径信息(例如，接收端口和发送端口的信息)携带在该寻址请求消息中，由此寻址请求消息可以携带各个转发节点处的转发路径信息。在目标RE在针对寻址请求消息发送寻址响应消息时，可以将寻址请求消息中的转发路径信息携带在寻址响应消息中，以便该寻址响应消息按照对应的寻址请求消息的反向路径返回至REC。
第二种方式中，对于各个RE，在电力线端口或下联CPRI端口收到寻址响应消息，向上联CPRI端口转发寻址响应消息。
例如，RE4在电力线端口收到RE5的寻址响应消息后，则可以将该寻址请求消息封装为CPRI协议的消息，并通过上联CPRI端口转发该寻址响应消息，该寻址响应消息经过RE3、RE2和RE1的透传到达REC；RE3在电力线端口收到RE5的寻址响应消息后，则可以将该寻址响应消息封装为CPRI协议的消息，并通过上联CPRI端口转发该寻址响应消息，该寻址响应消息经过RE2和RE1的透传到达REC。RE2和RE1通过电力线收到RE5 的寻址响应消息的处理与RE3和RE4类似。REC可以从多条寻址响应消息的路径中，选择与RE5进行通信的备用线路；例如，将首次收到的来自RE5的响应消息的路径确定为备用线路，例如，该首次收到的寻址响应消息为在RE3处进行CPRI协议封装处理的消息，则REC通过该首次收到的寻址响应消息中封装的RE3的信息，则确定与RE5进行通信的备用线路的路径为待发消息通过CPRI线路经由RE1和RE2的透传到达RE3，再由RE3通过电力线发送到RE5。
在图5中，REC与RE1和RE2属于同一电力线网络，RE3、RE4和RE5属于另外一个电力线网络；并假设RE4至RE5的CPRI通信线路故障，例如RE5的硬件故障或RE5的光口参数不合适导致的RE4至RE5的CPRI通信线路故障。在判断与RE5进行通信的主线路故障之后，REC通过电力线端口和CPRI端口发送针对RE5寻址请求消息。在图5中，由于REC与RE5不属于相同的电力线网络，则REC可通过电力线端口和CPRI端口，或通过CPRI端口发送寻址请求消息。可选地，REC可以不对是否与RE5属于相同的电力线网络进行判断，直接根据其所属的CPRI端口和电力线端口发送寻址请求消息。REC发送的寻址请求消息可以通过电力线直接到达RE1和RE2，并通过CPRI通信线路到达RE1。
对于各个非目标RE，寻址请求消息的处理可以满足以下原则：若在上联CPRI端口收到寻址请求消息，则向电力线端口和下联CPRI端口转发；若在电力线端口收到寻址请求消息，则丢弃该寻址请求消息；对于目标RE，寻址请求消息的处理可以满足以下原则：在电力线端口收到寻址请求消息，在电力线端口回寻址响应消息。
例如，对于RE1而言，通过上联CPRI端口接收到寻址请求消息，则可以通过下联CPRI端口和电力线端口转发寻址请求消息；通过电力线端口收到寻址请求消息，则可以丢弃该寻址请求消息。
例如，对于RE2而言，通过上联CPRI端口接收到经RE1转发的寻址请求消息，则可以通过下联CPRI端口和电力线端口转发寻址请求消息；通过电力线端口收到寻址请求消息，则可以丢弃该寻址请求消息。
例如，对于RE3而言，通过上联CPRI端口收到经RE2转发的寻址请求消息，则可以通过下联CPRI端口和电力线端口转发寻址请求消息。
例如，对于RE4而言，通过上联CPRI端口接收经RE3转发的寻址请求消息，通过下联CPRI端口和电力线端口转发寻址请求消息；通过电力线端口收到寻址请求消息，则可以丢弃该寻址请求消息。
例如，对于RE5而言，RE5通过电力线端口收到经RE3和RE4通过电力线转发的寻址请求消息，并分别通过电力线端口发送针对RE3和RE4转发的寻址请求消息的寻址响应消息。因为RE4至RE5的CPRI线路故障，则RE5无法收到RE4通过下联CPRI端口转发的寻址请求消息。
而对于寻址响应消息的返回路径，可以按照以下两种方式实现：
在第一种方式中，各个RE在转发寻址请求消息时，可以将寻址请求消息在自身的转发路径信息(例如，接收端口和发送端口的信息)携带在该寻址请求消息中，由此寻址请求消息可以携带各个转发节点处的转发路径信息。在目标RE在针对寻址请求消息发送寻址响应消息时，可以将寻址请求消息中的转发路径信息携带在寻址响应消息中，以便该寻址响应消息按照对应的寻址请求消息的反向路径返回至REC。
第二种方式中，对于各个RE，在电力线端口或下联CPRI端口收到寻址响应消息，向上联CPRI端口转发寻址响应消息。
例如，RE4在电力线端口收到RE5的寻址响应消息后，则可以将该寻址请求消息封装为CPRI协议的消息，并通过上联CPRI端口转发该寻址响应消息，该寻址响应消息经过RE3、RE2和RE1的透传到达REC；RE3在电力线端口收到RE5的寻址响应消息后，则可以将该寻址响应消息封装为CPRI协议的消息，并通过上联CPRI端口转发该寻址响应消息，该寻址响应消息经过RE2和RE1的透传到达REC.REC可以从多条寻址响应消息中的路径中，选择与RE5进行通信的备用线路；例如，将首次收到的来自RE5的响应消息的路径确定为备用线路，例如，该首次收到的寻址响应消息为在RE3处进行CPRI协议封装处理的消息，则REC通过该首次收到的寻址响应消息中封装的RE3的信息，则确定与RE5进行通信的备用线路的路径为待发消息通过CPRI线路经由RE1和RE2的透传到达RE3，再由RE3通过电力线发送到RE5。
因此，在本发明实施例中，在REC确定与某一RE进行通信的主线路故障后，REC可以针对该RE发送寻址请求消息，根据该RE回复的寻址响应消息的路径判断确定与该主线路故障的RE进行通信的备用线路，由此在主 线路故障时不需要人工下站处理，减少了维护成本，并降低了业务中断时间，从而提升用户体验。
应理解，在本发明实施例中，两者之间属于同一电力线网络，意味着两者之间可以只通过电力线进行通信。两者之间不属于相同的电力线网络，意味着两者之前无法只通过电力线进行通信。
因此，在本发明实施例中，在REC确定与任一RE的通信的主线路故障时，可以确定与该主线路故障的RE进行通信的备用线路，并通过备用线路与该主线路故障的RE进行通信，由此在主线路故障时不需要人工下站处理，减少了维护成本，并降低了业务中断时间，从而提升用户体验。
图6是根据本发明实施例的REC200的示意性框图。如图6所示，该REC200包括：
第一确定单元210，用于确定REC200与第一RE进行通信的主线路故障；
第二确定单元220，用于确定REC200与第一RE进行通信的备用线路；
通信单元230，用于通过备用线路与第一RE进行通信。
因此，在本发明实施例中，在第一确定单元确定REC200与任一RE的通信的主线路故障时，第二确定单元220可以确定REC200与该主线路故障的RE进行通信的备用线路，通信单元230通过备用线路与该主线路故障的RE进行通信，由此在主线路故障时不需要人工下站处理，减少了维护成本，并降低了业务中断时间，从而提升用户体验。
在本发明实施例中，REC200还可以称作为BBU，RE还可以称作为RRU。
在本发明实施例中，主线路可以是CPRI通信线路；备用线路可以是电力线线路，或者为电力线加CPRI通信线路。当然，主线路可以是电力线线路或为电力线加CPRI通信线路，备用线路为CPRI通信线路，或者为其他方式，具体可以根据应用场景而定，本发明实施例并不对此进行限定。但是本发明实施例以主线路为CPRI通信线路，备用线路为电力线线路或者为电力线加CPRI通信线路为主进行说明。
由于REC和RE天然具有电力线网络供电，本发明实施例在REC与RE的CPRI通信线路出现故障时，借用REC和RE的电力线网络实现REC与RE的通信。
在本发明实施例中，CPRI通信线路是指支持CPRI协议的线路；CPRI通信线路可以包括光纤、同轴电缆和以太网线中的至少一种。
在本发明实施例中，通信单元230具体用于：
通过备用线路对第一RE进行复位或升级以恢复REC与该第一RE进行通信的主线路。
例如，在第一RE的主线路故障的原因是该RE的光口参数不合适，则可以通过备用线路修改该RE的光口参数，由此可以恢复主线路。
再例如，RE的硬件发生问题，导致RE无法正常启动，需要进行一下上下电才能恢复，因为此时RE已经出现问题，所以无法通过CPRI通信线路再与其成功通信。则第二确定单元220可以确定备用线路，该备用线路可以包括电力线，通信单元230可以通过备用线路向RE发指示信息，指示RE进行上下电。
在本发明实施例中，REC200可以实时(例如周期性或初始化阶段)扫描控制的所有RE中主线路故障的RE，并确定主线路故障的RE的备用线路；REC200也可以通过与某一RE互发心跳消息，确定与该RE进行通信的主线路故障，并确定与该RE进行通信的备用线路。为了便于理解，以下将结合实施例C和实施例D对这两种情况进行详细说明。
实施例C

因此，在本发明实施例中，REC可以针对所有RE发送寻址请求消息，根据各个RE回复的寻址响应消息的路径判断主线路故障的RE，并确定与该主线路故障的RE进行通信的备用线路，由此在主线路故障时不需要人工下站处理，减少了维护成本，并降低了业务中断时间，从而提升用户体验。
实施例D
在该种实施例中，REC200可以通过REC200和RE之间的心跳判断REC200与RE进行通信的主线路是否故障。具体地，REC200和RE之间通过主线路相互发心跳消息，如果REC200连续预定次数没有收到RE发送的心跳信息，则确定REC与RE进行通信的主线路故障。
可选地，如图8所示，第二确定单元220包括：第二发送子单元221，用于在第一确定单元210确定REC200与第一RE进行通信的主线路故障之后，通过电力线端口和CPRI端口中的至少一种发送针对第一RE的寻址请求消息；第二接收子单元222，用于接收来自第一RE的至少一个寻址响应消息；第二确定子单元223，用于根据第二接收子单元222接收的至少一个寻址响应消息的路径，确定与第一RE进行通信的备用线路。

应理解，实施例D中的REC200可以对应于实施例B中的REC，并且REC200可以具有实施例B中REC的相应功能，为了简洁，在此不再赘述。
因此，在本发明实施例中，在REC确定与某一RE进行通信的主线路故障后，REC可以针对该RE发送寻址请求消息，根据该RE回复的寻址响应消息的路径判断确定与该主线路故障的RE进行通信的备用线路，由此在主线路故障时不需要人工下站处理，减少了维护成本，并降低了业务中断时间，从而提升用户体验。
应理解，在本发明实施例中，两者之间属于同一电力线网络，意味着两者之间可以只通过电力线进行通信。两者之间不属于相同的电力线网络，意味着两者之前无法只通过电力线进行通信。
因此，在本发明实施例中，在REC确定与任一RE的通信的主线路故障时，可以确定与该主线路故障的RE进行通信的备用线路，并通过备用线路与该主线路故障的RE进行通信，由此在主线路故障时不需要人工下站处理，减少了维护成本，并降低了业务中断时间，从而提升用户体验。

应理解，在本发明实施例中，RE300可以为寻址请求消息中唯一的针对对象，则此时，RE300可以对应于实施例B中的RE5，并且可以实现RE5中的相应功能。
因此，在本发明实施例中，在REC确定与某一RE进行通信的主线路故障后，REC可以针对该RE发送寻址请求消息，RE根据REC发送的寻址请求消息回复寻址响应消息，从而REC可以根据该RE回复的寻址响应消息的路径判断确定与该主线路故障的RE进行通信的备用线路，由此在主线路故障时不需要人工下站处理，减少了维护成本，并降低了业务中断时间，从而提升用户体验。
还应理解，在本发明实施例中，寻址请求消息的针对对象还可以包括除RE300之外的其他RE。为了便于理解，以下结合实施例E对这种情况进行详细说明。

在实现过程中，上述方法的各步骤可以通过处理器712中的硬件的集成逻辑电路或者软件形式的指令完成。结合本发明实施例所公开的方法的步骤可以直接体现为硬件处理器执行完成，或者用处理器中的硬件及软件模块组合执行完成。软件模块可以位于随机存储器，闪存、只读存储器，可编程只读存储器或者电可擦写可编程存储器、寄存器等本领域成熟的存储介质中。该存储介质位于存储器711，处理器712读取存储器711中的信息，结合其硬件完成上述方法的步骤。为避免重复，这里不再详细描述。
可选地，在本发明实施例中，处理器712可以包括两个子处理器，其中，一个子处理器用于通过电力线与BBU或其他RE进行通信，另一个子处理器用于通过CPRI线路与BBU或其他RE进行通信，这两个子处理器分别相互独立，则两个子处理器同时发生故障的可能性较小，所以能大幅度提高系统的性能。
可选地，RE700可以对应于实施例B中的RE1、RE2、RE3和RE4中的任一RE，并且可以实现该任一RE的功能，为了简洁，在此不再赘述。
因此，在本发明实施例中，在REC确定与某一RE进行通信的主线路故障后，REC可以针对该某一RE发送寻址请求消息，非目标RE在收到该寻址请求消息时，转发该寻址请求消息，目标RE在收到该寻址请求消息时，根据REC发送的寻址请求消息回复寻址响应消息，从而REC可以根据该目标RE回复的寻址响应消息的路径判断确定与该主线路故障的目标RE进行通信的备用线路，由此在主线路故障时不需要人工下站处理，减少了维护成本，并降低了业务中断时间，从而提升用户体验。
图14是根据本发明实施例的信息传输方法800的示意性流程图。如图13所示，该方法800包括：
S810，REC确定与第一RE进行通信的主线路故障；
S820，所述REC确定与所述第一RE进行通信的备用线路；
S830，所述REC通过所述备用线路与所述第一RE进行通信。
因此，在本发明实施例中，REC在与任一RE的通信的主线路故障时，可以确定与该主线路故障的RE进行通信的备用线路，通过备用线路与该主线路故障的RE进行通信，由此在主线路故障时不需要人工下站处理，减少了维护成本，并降低了业务中断时间，从而提升用户体验。
在本发明实施例中，REC还可以称作为BBU，RE还可以称作为RRU。
在本发明实施例中，主线路可以是CPRI通信线路；备用线路可以是电力线线路，或者为电力线加CPRI通信线路。当然，主线路可以是电力线线路或为电力线加CPRI通信线路，备用线路为CPRI通信线路，或者为其他方式，具体可以根据应用场景而定，本发明实施例并不对此进行限定。但是本发明实施例以主线路为CPRI通信线路，备用线路为电力线线路或者为电力线加CPRI通信线路为主进行说明。
由于REC和RE天然具有电力线网络供电，本发明实施例在REC与RE的CPRI通信线路出现故障时，借用REC和RE的电力线网络实现REC与RE的通信。
在本发明实施例中，CPRI通信线路是指支持CPRI协议的线路；CPRI通信线路可以包括光纤、同轴电缆和以太网线中的至少一种。
在本发明实施例中，S830中，REC通过备用线路与该主线路故障的第一RE进行通信，可以包括：
REC通过备用线路发送指示信息，以对第一RE进行复位或升级以恢复REC与该第一RE进行通信的主线路。
例如，在第一RE的主线路故障的原因是该RE的光口参数不合适，则可以通过备用线路修改该RE的光口参数，由此可以恢复主线路。
再例如，RE的硬件发生问题，导致RE无法正常启动，需要进行一下上下电才能恢复，因为此时RE已经出现问题，所以无法通过CPRI通信线路再与其成功通信。可以确定备用线路，该备用线路可以包括电力线，通信单元230可以通过备用线路向RE发指示信息，指示RE进行上下电。
在本发明实施例中，REC可以实时(例如周期性或初始化阶段)扫描控制的所有RE，并确定所有RE中主线路故障的RE，并确定主线路故障的RE的备用线路；REC也可以通过与某一RE互发心跳消息，确定与该RE进行通信的主线路故障，并确定与该RE进行通信的备用线路。为了便于理解，以下将结合实施例I和实施例K对这两种情况进行详细说明。
实施例I
REC可以实时(例如周期性或初始化阶段)扫描控制的所有RE，并确定所有RE中主线路故障的RE(第一RE)，并确定主线路故障的RE的备用线路。
可选地，S810中，所述REC确定与第一RE进行通信的主线路故障，包括：所述REC通过CPRI端口或通过电力线端口和CPRI端口，发送针对控制的所有RE的寻址请求消息；所述REC接收来自至少一个RE的寻址响应消息，其中，所述至少一个RE包括所述第一RE；在来自所述第一RE的至少一个寻址响应消息的路径不包括主线路时，所述REC确定通过与所述第一RE进行通信的主线路故障；S820中，所述REC确定与所述第一RE进行通信的备用线路，包括：在来自所述第一RE的至少一个寻址响应消息的路径不包括主线路时，所述REC根据所述至少一个寻址响应消息的路径，确定与所述第一RE进行通信的备用线路。
可选地，所述REC通过CPRI端口或通过电力线端口和CPRI端口，发送针对控制的所有RE的寻址请求消息，包括：在所述所有RE中存在与所述REC属于相同电力线网络的RE时，所述REC通过CPRI端口和电力线端口，发送针对所述所有RE的寻址请求消息；在所述所有RE中不存在与所述REC属于相同电力线网络的RE时，所述REC通过CPRI端口或通过CPRI端口和电力线端口，发送针对所述所有RE的寻址请求消息。
可选地，S820中，所述REC确定与所述第一RE进行通信的备用线路，包括：
所述REC将首次收到的来自所述第一RE的寻址响应消息的路径确定为与所述第一RE进行通信的备用线路。
应理解，实施例I中的方法可以由实施例A中的REC实现，并且实施例A中的REC所实现的动作可以属于实施例I的可选实施例，为了简洁， 在此不再赘述。
因此，在本发明实施例中，REC可以针对所有RE发送寻址请求消息，根据各个RE回复的寻址响应消息的路径判断主线路故障的RE，并确定与该主线路故障的RE进行通信的备用线路，由此在主线路故障时不需要人工下站处理，减少了维护成本，并降低了业务中断时间，从而提升用户体验。
实施例K
在该种实施例中，在REC通过与第一RE互发心跳消息确定确定与该RE进行通信的主线路故障之后，确定与该RE进行通信的备用线路，通过备用线路与该第一RE进行通信。
可选地，S820中，所述REC确定与所述第一RE进行通信的备用线路，包括：在所述REC确定通过与所述第一RE进行通信的主线路故障之后，所述REC通过电力线端口和CPRI端口中的至少一种发送针对所述第一RE的寻址请求消息；所述REC接收来自所述第一RE的至少一个寻址响应消息；所述REC根据所述至少一个寻址响应消息的路径，确定与所述第一RE进行通信的备用线路。
可选地，所述REC通过电力线端口和CPRI端口中的至少一种发送针对所述第一RE的寻址请求消息，包括：在所述REC与所述第一RE属于同一电力线网络时，所述REC通过电力线端口或通过CPRI端口和电力线端口，发送针对所述第一RE的寻址请求消息；在所述REC与所述第一RE不属于同一电力线网络时，所述REC通过CPRI端口或通过CPRI端口和电力线端口，发送针对所述第一RE的寻址请求消息。
可选地，S830中，所述REC确定与所述第一RE进行通信的备用线路，包括：所述REC将首次收到的来自所述第一RE的寻址响应消息的路径确定为与所述第一RE进行通信的备用线路。
应理解，实施例K中的方法可以由实施例B中的REC实现，并且实施例B中的REC所实现的动作可以属于实施例K的可选实施例，为了简洁，在此不再赘述。
因此，在本发明实施例中，在REC确定与某一RE进行通信的主线路故障后，REC可以针对该RE发送寻址请求消息，根据该RE回复的寻址响应消息的路径判断确定与该主线路故障的RE进行通信的备用线路，由此在主 线路故障时不需要人工下站处理，减少了维护成本，并降低了业务中断时间，从而提升用户体验。
应理解，在本发明实施例中，两者之间属于同一电力线网络，意味着两者之间可以只通过电力线进行通信。两者之间不属于相同的电力线网络，意味着两者之前无法只通过电力线进行通信。
因此，在本发明实施例中，在REC确定与任一RE的通信的主线路故障时，可以确定与该主线路故障的RE进行通信的备用线路，并通过备用线路与该主线路故障的RE进行通信，由此在主线路故障时不需要人工下站处理，减少了维护成本，并降低了业务中断时间，从而提升用户体验。
图15是根据本发明实施例的信息传输方法900的示意性流程图。如图15所示，该方法900包括：
S910，第一RE通过第一端口接收REC发送的寻址请求消息，所述第一端口为上联CPRI端口或电力线端口；
S920，根据所述寻址请求消息，所述第一RE确定所述寻址请求消息针对对象包括所述第一RE；
S930，所述第一RE通过所述第一端口向所述REC发送第一寻址响应消息。
可选地，所述寻址请求消息中携带从所述REC到所述第一RE的转发路径信息；在所述通过第一端口向所述REC发送第一寻址响应消息之前，所述方法900还包括：所述第一RE在所述第一寻址响应消息中携带从所述REC到所述第一RE的转发路径信息，以便所述第一寻址响应消息按照所述寻址请求消息的反向路径返回至所述REC。
应理解，在本发明实施例中，第一RE可以为寻址请求消息中唯一的针对对象，则此时方法900可以由实施例B中的RE5实现，即方法900中的第一RE对应于实施例B中的RE5，并且实施例B中的RE5所实现的动作可以属于该方法900的可选实施例，为了简洁，在此不再赘述。
因此，在本发明实施例中，在基站确定与某一RE进行通信的主线路故障后，REC可以针对该RE发送寻址请求消息，根据该RE回复的寻址响应消息的路径判断确定与该主线路故障的RE进行通信的备用线路，由此在主线路故障时不需要人工下站处理，减少了维护成本，并降低了业务中断时间，从而提升用户体验。

因此，在本发明实施例中，REC可以针对所有RE发送寻址请求消息，根据各个RE回复的寻址响应消息的路径判断主线路故障的RE，并确定与该主线路故障的RE进行通信的备用线路，由此在主线路故障时不需要人工 下站处理，减少了维护成本，并降低了业务中断时间，从而提升用户体验。
