具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本公开一示例性实施例提供了一种无线链路失败的处理方法，该方法的执行主体可以为终端，该终端可以是手机、平板电脑等移动终端。该终端为5G终端，可以接入NR通信系统，或者，也可以同时接入NR通信系统和LTE(Long Term Evolution，长期演进)通信系统。
本发明实施例的系统架构中，终端可以分别与多个网络设备建立有通信连接，多个网络设备可以包括一个或多个DU，还可以包括LTE基站，也就是说终端不但可以接入多个DU，还可以同时接入LTE基站，相应的网络架构可以如图1所示。在终端与网络侧的DU、LTE基站之间的通信连接中，可以包括至少一个承载信令的通信连接，用于传输控制信息， 还可以包括至少一个承载数据的通信连接，用于传输数据信息。终端的主基站可以为LTE基站，也可以为某个DU。
终端可以包括处理器、存储器、收发器等部件。处理器，可以为CPU(Central Processing Unit，中央处理单元)等，可以用于检测通信连接是否出现RLF、判定是否存在承载信令的通信连接、进行连接重建，等处理。存储器，可以为RAM(Random Access Memory，随机存取存储器)，Flash(闪存)等，可以用于存储接收到的数据、处理过程所需的数据、处理过程中生成的数据等。收发器，可以用于与DU或LTE基站进行数据传输，例如，发送通知消息等，可以包括天线、匹配电路、调制解调器等。终端还可以包括输入部件、显示部件、音频输出部件等。输入部件可以是触摸屏、键盘、鼠标等。音频输出部件可以是音箱、耳机等。
如图2所示，该方法的处理流程可以包括如下的步骤。
在步骤210中，检测到终端与上述多个网络设备中的第一网络设备之间的第一通信连接出现RLF。
在实施中，终端在接入通信网络后，在正常工作的过程中，会实时检测它的每一个通信连接是否出现RLF。终端通过某个通信连接向网络设备发送数据时，如果数据发送失败，会重新发送，当该通信连接的连续重发失败次数达到预设阈值时，则可以判定该通信连接出现RLF。此时，出现RLF的第一通信连接可以是承载信令的通信连接，也可以是承载数据的通信连接。
在步骤220中，如果终端的其它通信连接中存在承载信令的第二通信连接，则通过第二通信连接，向第二网络设备发送第一通信连接出现RLF的通知消息，如果终端的其它通信连接中不存在承载信令的通信连接，则对第一通信连接，进行连接重建。
在实施中，终端在与DU或LTE基站建立通信连接时，网络侧会为其配置相应的通信连接用于承载信令或承载数据，并通知终端。这样，终端可以记录它的通信连接中哪些是承载信令的通信连接，哪些是承载数据的通信连接。
当终端检测到第一通信连接出现RLF时，可以确认其它正常工作的通信连接中是否存在承载信令的通信连接。如果不存在承载信令的通信连接，则说明当前终端已经无法与网络侧传输控制信息，此时需要重建第一通信连接，以保证终端的正常通信。如果存在承载信令的通信连接(即第二通信连接)，则当前可以通过此承载信令的通信连接，传输控制信息，为了防止终端的通信中断，可以不对第一通信连接进行重建，此时，只需通过第二通信连接向对应的网络设备(即第二网络设备)发送通知消息，以通知网络侧第一通信连接出现RLF。如果此时有多个承载信令的通信连接，终端可以通过其中的一个通信连接发送通知消息，这样可以减少资源占用，或者，也可以通过多个通信连接分别发送通知消息，这样可以提高通知消息发送的可靠性。该通知消息可以是RRC(Radio Resource Control，是指无线资源控制)消息。第二网络设备接收到通知消息后，可以通知第一网络设备删除关于第一通信连接的配置信息。
本发明实施例中，在CU和DU组成的网络架构下，终端接入网络的方式多种多样，下面对不同的情况进行详细的介绍。
情况一，终端接入的多个网络设备中除了包括DU还包括LTE基站，LTE基站为终端的主基站，第一网络设备为LTE基站，即终端与LTE基站之间的通信连接出现RLF。相应的，步骤220的处理可以如下：如果终端与DU之间的通信连接中存在承载信令的第二通信连接，则通过第二通信连接，向对应的DU发送第一通信连接出现RLF的通知消息，如果终端与DU之间的通信连接中不存在承载信令的通信连接，则对第一通信连接，进行连接重建。
在实施中，网络架构图可以如图3a所示，这种情况下，终端与主基站之间的通信连接出现RLF。此时终端可以检测NR侧的各通信连接中是否存在承载信令的通信连接。如果NR侧存在承载信令的第二通信连接，则可以向第二通信连接所连接的DU发送RRC通知信息，以通知该DU第一通信连接出现RLF，该DU则可以通知LTE基站删除关于第一通信连接的配置信息。如果NR侧不存在承载信令的第二通信连接，终端则可以对第一通信连接，进行连接重建。
情况二，终端接入的多个网络设备中除了包括DU还包括LTE基站，LTE基站为终端的主基站，第一网络设备为第一DU，第一DU可以是终端连接的任一DU，即终端与某一DU之间的通信连接出现RLF。相应的，步骤220的处理可以如下：向LTE基站发送第一通信连接出现RLF的通知消息。
在实施中，网络架构图可以如图3b所示，这种情况下，终端与某个DU之间的通信连接出现RLF，而此时与主基站之间的通信连接没有问题，也就是说此时终端还存在可以使用的承载信令的通信连接。此时，终端可以向主基站发送第一通信连接出现RLF的RRC通知消息。主基站可以通知第一DU删除关于第一通信连接的配置数据。
情况三，终端接入的多个网络设备中除了包括DU还包括LTE基站，终端的主基站在NR侧，且主基站对应的DU为第二DU，即第二DU与CU共同作为终端的主基站，第一网络设备为LTE基站，即终端与LTE基站之间的通信连接出现RLF。相应的，步骤220的处理可以如下：向第二DU发送第一通信连接出现RLF的通知消息。
在实施中，网络架构图可以如图3c所示，这种情况下，终端与LTE基站之间的通信连接出现RLF，LTE基站为辅基站，此时终端与主基站之间的通信连接没有问题，也就是说此时终端还存在可以使用的承载信令的通信连接。此时，终端可以向第二DU发送第一通信连接出现RLF的RRC通知消息。第二DU可以通知LTE基站删除关于第一通信连接的配置数据。
情况四，终端接入的多个网络设备中除了包括DU还包括LTE基站，终端的主基站在NR侧，第一网络设备为第一DU，即终端与某一DU之间的通信连接出现RLF。相应的，步骤220的处理可以如下：如果终端与第一DU之外的其它DU之间的通信连接中存在承载信令的第二通信连接，则通过第二通信连接，向对应的DU发送第一通信连接出现RLF 的通知消息；如果终端与第一DU之外的其他DU之间的通信连接中不存在承载信令的通信连接，且终端与LTE基站之间的第三通信连接是承载信令的通信连接，则通过第三通信连接，向LTE基站发送第一通信连接出现RLF的通知消息；如果终端与其他DU之间的通信连接中不存在承载信令的通信连接，且终端与LTE基站之间的第三通信连接不是承载信令的通信连接，则对第一通信连接，进行连接重建。
在实施中，网络架构图可以如图3d所示。当终端与第一DU之间的通信连接出现RLF时，如果NR侧有可用的承载信令的通信连接，则可以优先使用该通信连接，发送第一通信连接出现RLF的通知消息。如果NR侧没有可用的承载信令的通信连接，但LTE侧有承载信令的第三通信连接，则可以使用此第三通信连接，发送通知消息。如果NR侧没有可用的承载信令的通信连接，且LTE侧也没有可用的承载信令的通信连接，则对第一通信连接，进行连接重建。
情况五，终端接入的多个网络设备中只包括DU，第一网络设备为第一DU，即终端与某一DU之间的通信连接出现RLF。网络架构图可以如图3e所示，相应的，步骤220的处理可以如下：如果终端的其它DU之间的通信连接中存在承载信令的第二通信连接，则通过第二通信连接，向对应的DU发送第一通信连接出现RLF的通知消息，如果终端的其它DU之间的通信连接中不存在承载信令的通信连接，则对第一通信连接，进行连接重建。
下面，对重建第一通信连接的处理方式进行详细说明。
如果第一网络设备为第一DU，且终端与第一DU之外的其它DU之间存在承载数据的第四通信连接，则通过第四通信连接对应的链路，对第一通信连接，进行连接重建；如果第一网络设备为第一DU，且终端与第一DU之外的其它DU之间不存在承载数据的通信连接，则通过第一通信连接对应的链路，对第一通信连接，进行连接重建；如果多个网络设备中还包括LTE基站，且第一网络设备为LTE基站，则通过第一通信连接对应的链路，对第一通信连接，进行连接重建。
在实施中，在判定需要进行链路重建时，说明终端当前没有可用的承载信令的通信连接，然而这时终端可能还有可用的承载数据的通信连接，这些承载数据的通信连接没有发生RLF，说明建立通信连接的链路的信号质量较高，可以考虑使用相应的链路重建第一通信连接。如果出现RLF的第一通信连接在NR侧，则可以通过NR侧的承载数据的通信连接所在的链路，重建第一通信连接。此时，如果NR侧存在可用的承载数据的通信连接，则可以使用此通信连接(即第四通信连接)对应的链路，对第一通信连接，进行连接重建。如果NR侧不存在承载数据的通信连接，则仍然使用第一通信连接原属的链路，对第一通信连接，进行连接重建。另外，如果出现RLF的第一通信连接在LTE侧，则仍然使用第一通信连接原属的链路，对第一通信连接，进行连接重建。
本公开实施例中，检测到终端与第一网络设备之间的第一通信连接出现RLF，如果终端的其它通信连接中存在承载信令的第二通信连接，则通过第二通信连接，向第二网络设 备发送第一通信连接出现RLF的通知消息，如果终端的其它通信连接中不存在承载信令的通信连接，则对第一通信连接，进行连接重建。这样，可以实现在5G网络架构下的RLF处理。
