技术领域
本公开涉及通信技术领域，尤其涉及一种信息处理方法及装置。
背景技术
未来的移动通信系统将支持更大的传输带宽和更高的传输速率，带宽将达到GHz级别，传输速率达到10Gbps级别。为了应对这样的场景，大量高频小站密集部署将是一个很普遍的部署场景。为了使小站之间更好的协作和高效工作，有一个集中节点统一管理和作为数据锚点，无论是对系统效率还是用户体验，都是较好的一种解决方式。
在相关的通信系统中，UE(User Equipment，用户设备)和eNB(evolved Node B，演进型基站)之间的数据传输，通常经过PDCP(Packet Data Convergence Protocol，分组数据汇聚协议)，RLC(Radio Link Control，无线链路层控制协议)，MAC(Media Access Control，介质访问控制)和PHY(Physical Layer，物理层)的传输。针对主基站小区与从属基站小区重叠覆盖且使用相同或不同的频率，或者只存在从属基站小区覆盖小区之间的回传链路非理想的场景，引入了双连接技术。双连接指的是，用户设备由多个回传链路不理想的网络节点提供无线资源。也就是说，用户设备同时与MeNB(Master eNB，主基站)和SeNB(Secondary eNB，从属基站)存在空口连接，这意味着MeNB与SeNB可以同时为UE提供服务。
在双连接的架构中，用户数据可以在不同eNB之间进行分流处理，从RLC及以下进行两个eNB的分别处理。在这种架构下，通过X2接口的信令过程，将SeNB和MeNB之间进行流量控制，以及X2接口传输失败的反馈。

具体实施方式
下面将结合附图和实施例，对本公开的具体实施方式作进一步详细描述。以下实施例用于说明本公开，但不用来限制本公开的范围。
图1为相关移动通信系统中的用户面协议栈。如图1所示，每一层完成不同的数据处理。PDCP(Packet Data Convergence Protocol，分组数据汇聚协 议)主要是进行安全操作和头压缩解压缩处理，例如加密和完整性保护；ROHC(Robust Header Compression，健壮性包头压缩)压缩和解压缩等；RLC(Radio Link Control，无线链路层控制协议)主要完成数据的分段级联和按序递交及ARQ(Automatic Repeat ReQuest，自动重传请求)数据传输保障；MAC(Media Access Control，介质访问控制)主要完成调度和不同逻辑信道的级联处理及HARQ(Hybrid Automatic Repeat reQuest，混合自动重传请求)操作；物理层完成传输块成包和空口发送。
在相关技术中，X2接口的流量控制机制重点是对MeNB(Master eNB，主基站)和SeNB(Secondary eNB，从属基站)之间的流量进行控制，并且对X2接口的传输结果进行反馈。但相关的机制并不足够，例如当一条链路是高频率传输，由于发生闪断等情况而在一段时间之内不能够正确传输时，利用相关的X2接口的流量控制机制无法应对，从而将造成该链路的持续恶化，分配到该链路的数据无法正常传输。
本公开实施例的核心思想如下：在多连接或者承载分离的场景下，当辅节点的其中一条链路满足一定的恶化条件时，辅节点可以将链路恶化指示发送给主控节点，并且可选的，将链路的数据发送情况反馈给主控节点，以利于主控节点正确的安排所有未传输或者未传输成功的数据包进行快速的重传。在等待链路达到恢复的条件之后，辅节点将链路恢复的指示发送给主控节点，以使主控节点可以继续安排数据在该路径上的传输。
基于上述核心思想的两个节点之间传输状态反馈的方法，可以使节点之间及时的交互链路情况和数据传输状态。当一条链路发生异常时，可以及时的在其它链路进行接续传输，并对恶化链路进行应对，积极处理了异常情况，避免了用户数据体验的中断，降低了恢复处理的复杂度，提升了层二对数据包的处理效率，将更适用于未来5G CU/DU或者多连接等部署场景。
一般来说，主控节点是数据的主要集中式锚点。在双连接或者多连接的架构中主控节点指的是MeNB，辅节点指的是SeNB；在CU/DU架构中，主控节点指的是CU(Central Unit，中央单元)节点，辅节点指的是DU(Distributed Unit，分布式单元)。
图2为本公开实施例的信息处理方法的流程图。图2所示的信息处理方 法应用于辅节点。所述辅节点包括但不限于为SeNB，DU等。该信息处理方法包括步骤101-103。
步骤101、获取目标链路的链路状态信息。
在具体应用中，辅节点可对其连接的各个链路的状态进行监控，以获得各个链路的链路状态信息。其中，任意一条链路都可作为在此的目标链路。
其中，所述链路状态信息包括但不限于为：所述目标链路的质量监测结果，所述目标链路的数据传输的平均成功率；或者是RLC(Radio Link Control，无线链路层控制协议)的重传次数等。
步骤102、根据所述链路状态信息确定所述目标链路是否发生链路异常。
在此步骤中，确定所述链路状态信息是否满足预设的链路恶化条件。若所述链路状态信息满足预设的链路恶化条件，确定所述目标链路发生异常。
其中，所述链路恶化条件可通过RRC(Radio Resource Control，无线资源控制)信令进行配置。
例如，为避免虚警，当所述目标链路的质量监测结果不符合预定链路质量要求的持续时间达到第一预设值，或当所述目标链路的数据传输的平均成功率不符合预定成功率要求的持续时间达到第二预设值时，可认为目标链路发生异常。其中，该第一预设值和第二预设值可任意设置。或者发生了辅节点自身无法处理的情况，例如当RLC的重传次数达到最大值时，确定所述目标链路发生链路异常。
步骤103、当确定所述目标链路发生链路异常时，向主控节点发送链路异常指示信息，所述链路异常指示信息用于向所述主控节点指示所述目标链路发生链路异常。
在本公开实施例中，链路异常指示信息包括链路质量恶化指示信息或者数据传输状态信息。或者，为了使得主控节点进行相应的处理，链路异常指示信息还可同时链路质量恶化指示信息和数据传输状态信息。其中，链路质量恶化指示信息用于向主控节点指示目标链路发生了链路异常，而数据传输状态信息则可向主控节点详细的指示目标链路的数据传输情况，以便主控节点进行相应的处理。
由上可以看出，在本公开实施例中，当目标链路发生链路异常时，辅节 点可向主控节点发送链路异常指示信息，由主控节点根据该信息选择替代链路，并处理目标链路对应的数据。因此，利用本公开实施例的方案当目标链路发生异常时，可及时的在替代链路处理目标链路的数据，从而保证了数据传输的正常进行。
在图2所示的实施例的基础上，该信息处理方法还可包括如下步骤104-106。
步骤104、当所述目标链路的链路状态信息满足预设的链路恢复条件时，辅节点向所述主控节点发送链路质量恢复指示信息。
当辅节点的目标链路状况满足了某些预配置的恢复条件时，向主节点上报链路质量恢复指示信息，通知主基站该链路可以进行正常传输。其中预配置的恢复条件，可以由RRC信令配置。例如可以是链路质量监测的结果满足一定的门限。并且为了避免误报，可以为链路质量监测的结果满足一定的门限且维持了一定的时间或者次数，则判断链路恢复。
步骤105、辅节点停止所述目标链路上数据的传输。
其中，步骤104和105并无严格的先后关系。
在实际应用中，辅节点在上报了链路异常指示信息后，可直接停止在目标链路上数据的传输。或者，主控节点可向辅节点发送状态上报确认消息，以确认收到了链路异常指示信息。此时，步骤105也可在收到了主控节点发送的状态上报确认消息后执行，也即辅节点根据所述状态上报确认消息停止所述目标链路上数据的传输。
步骤106、辅节点接收所述主控节点发送的链路恢复确认消息。
在上述过程中，为了提高资源利用率，在步骤105辅节点停止了目标链路上的数据传输后，还可将所述目标链路复位，利用复位后的所述目标链路进行数据传输。或者，在步骤106之后，辅节点还可将所述目标链路复位，利用复位后的所述目标链路进行数据传输。或者，在步骤106之后，辅节点还在收到链路恢复确认消息后，将所述目标链路复位，利用复位后的所述目标链路进行数据传输。
也就是说，在本公开实施例中，辅节点停止所述目标链路上数据的传输可以是辅节点在上报了链路异常指示信息后即停止在目标链路上数据的传输， 也可以是在收到了主控节点发送的状态上报确认消息之后停止。
而辅节点将所述目标链路复位，利用复位后的所述目标链路进行数据传输这一操作，是发生在辅节点停止所述目标链路上数据的传输之后的。这一操作可在辅节点停止所述目标链路上数据的传输、辅节点向所述主控节点发送链路质量恢复指示信息之后进行，也可在辅节点停止所述目标链路上数据的传输、向所述主控节点发送链路质量恢复指示信息且收到了主控节点发送的链路恢复确认消息之后进行。
图3为本公开实施例的信息处理方法的流程图。图3所示的信息处理方法，应用于主控节点。所述主控节点包括但不限于为MeNB，CU等。该方法包括步骤201-202。
步骤201、接收辅节点发送的链路异常指示信息，所述链路异常指示用于指示目标链路发生链路异常。
其中，该链路异常指示信息包括：链路质量恶化指示信息；或者包括链路质量恶化指示信息和数据传输状态信息。
步骤202、根据所述链路异常指示信息为所述目标链路选择替代链路，在所述替代链路上处理所述目标链路对应的数据。
不同类型的主控节点在选择替代链路时的方式不同。例如，主基站具有自己的传输链路，当某条辅基站上报链路异常之后，主基站可以安排相关的数据在自己的链路上进行传输或者重传，也可以安排在其他辅基站的链路上进行传输或者重传。对于CU节点来说，它仅仅是一个控制节点，并不一定存在真正的传输链路，当一条DU的链路发生异常时，此时CU节点只能安排在其他DU链路进行传输和重传。主控节点在选择替代链路时，主要是考虑替代链路的链路质量，缓存能力，负荷大小等因素。当存在多条可选的替代链路时，从中选择链路质量好、负荷小、缓存能力强的链路作为在此的替代链路。
由上可以看出，在本公开实施例中，当目标链路发生链路异常时，辅节点可向主控节点发送链路异常指示信息，由主控节点根据该信息选择替代链路，并处理目标链路对应的数据。因此，利用本公开实施例的方案当目标链路发生异常时，可及时的在替代链路处理目标链路的数据，从而保证了数据 传输的正常进行。
本公开实施例的方案可应用于多种通信架构中，例如双/多连接承载分离架构、CU-DU PDCP-RLC split(分叉)架构、CU-DU Higher(更高)RLC-Lower RLC split(分叉)架构等。以下，结合不同的实施例详细描述一下本公开实施例的信息处理方法的实现过程。
图4为本公开实施例的信息处理方法的流程图。在图4所示的实施例中，以双/多连接承载分离架构为应用场景进行描述。在类似LTE(Long Term Evolution，长期演进)双连接3C架构中，同一个无线承载被分割到两条甚至多条链路上去传输，此时PDCP协议位于主基站节点(主控节点)，作为集中处理协议层，而RLC及以下的其他协议层分布在各个辅基站节点(辅节点)，进行数据包的分别处理。对于同一个逻辑信道的下行数据，先在主基站节点的PDCP层进行处理，之后被分配到不同的辅基站节点的路径上进行传输。
主基站节点和各个参与传输的辅基站节点之间建立接口，用于传输数据和状态信息等。传输的数据包内容是PDCP PDU(Protocol Data Unit，协议数据单元)。
图4所示的信息处理方法包括步骤301至步骤309。
步骤301、辅节点对自身的链路进行监测，获取目标链路的链路状态信息。
步骤302、辅节点根据所述链路状态信息确定所述目标链路是否发生链路异常。
步骤301和302的描述可以参照图1所示实施例中的步骤101和102。
步骤303、当确定所述目标链路发生链路异常时，辅节点向主控节点发送链路异常指示信息。
相应的，主控节点接收辅节点发送的链路异常指示信息。其中，所述链路异常指示信息用于向所述主控节点指示所述目标链路发生链路异常。在本公开实施例中，所述链路异常指示信息包括链路质量恶化指示信息和数据传输状态信息。这两个信息可以同时发送给主控节点，也可以分别发送给主控节点。
在本公开实施例，所述数据传输状态信息可以有不同的形式。
(1)第一种形式
数据传输状态信息包括：第一类数据包内容的序列号，第二类数据包内容的序列号，第三类数据包内容的序列号。
其中，第一类数据包内容包括：进行了空口传输且获得了对端ACK确认的PDCP PDU(Protocol Data Unit)；所述第二类数据包内容包括：进行了空口传输但未获得对端ACK(ACKnowledgement)确认的PDCP PDU；所述第三类数据包内容包括：未进行空口传输的PDCP PDU。
也就是说，在这种形式上，基于以上三类传输状态或者类型的PDCP PDU所对应的SN进行反馈，即分别以三个不同的列表，罗列三种状态下的PDCP PDU对应的SN。
主控节点收到了这种形式的数据传输状态信息后，可认为将所述第二类数据包内容和所述第三类数据包内容作为待处理数据。其中，第二类数据包内容需要重传，而第三类数据包内容是需要传输的。
(2)第二种形式
数据传输状态信息包括：第一类数据包内容对应的最大序列号、第二类数据包内容对应的最大序列号。
其中，所述第一类数据包内容对应的最大序列号小于或等于所述第二类数据包内容对应的最大序列号。所述第一类数据包内容包括：连续进行了空口传输且获得了对端ACK确认的PDCP PDU，所述第二类数据包内容包括：进行了空口传输的PDCP PDU。
也就是说，在这种形式中，如图5所示，辅节点上报已经进行空口传输并且获得对端ACK确认的PDCP PDU所对应的最大序列号SN1，进行了空口传输但未获得对端ACK确认的PDCP PDU所对应的最大序列号SN2。
一般来说，SN1小于或等于后者SN2，并且两者都小于或等于主控节点分配给该辅节点的数据内容包所对应的最大序列号SN3，即SN3≥SN2≥SN1。其中，该SN3的值可以由辅节点发送给主控节点。
当主控节点收到了这种形式的数据传输状态信息后，对于序列号小于SN1的所有PDCP PDU，主控节点可以认为全部进行了空口传输且收到了对端的ACK，因此这部分数据无需再次传输。
序列号位于SN1和SN2之间的PDCP PDU，其实是处于乱序被接收的状态，即其中仍旧可能有个别PDCP PDU被正确接收。但由于不是连续的，因此只能均算作进行了空口传输但未收到对端ACK的状态。主控节点需要将这部分PDCP PDU重传。或者，辅节点还可将序列号位于SN1和SN2之间的PDCP PDU中，进行了空口传输且收到了对端的ACK的PDCP PDU标识出来。在此，将其作为第四类数据包内容。然后，在数据传输状态信息中，还包括第四类数据包内容的序列号。此时，主控节点如果收到了四类数据包内容的序列号，可无需重传第四类数据包内容。
而对于序列号大于SN2的PDCP PDU，属于发送给该辅节点但还未被空口传输的PDCP PDU，因此主控节点需要传输这类PDCP PDU。
(3)第三种形式
数据传输状态信息包括：第五类数据包内容对应的最大序列号、第二类数据包内容的序列号。
所述第五类数据包内容包括：进行了空口传输的PDCP PDU(包括进行了空口传输且获得对端ACK确认的PDCP PDU，以及进行了空口传输但未获得对端ACK确认的PDCP PDU)。对于第五类数据包中的内容，再选择其中的一部分组成第二类数据包内容，包括：进行了空口传输但未获得对端ACK确认的PDCP PDU，所述第二类数据包内容的序列号小于所述第五类数据包内容对应的最大序列号。
也就是说，在这种形式下，辅节点向主控节点上报进行了空口传输的PDCP PDU对应的最大序列号，以及进行了空口传输但未获得对端ACK确认的PDCP PDU的序列号。
如图6所示，其中ACK_SN为进行了空口传输的PDCP PDU的最大序列号SN。对于序列号小于ACK_SN的PDCP PDU，如果没有收到对端的ACK确认，则将其序列号罗列在NACK_SN列表中。相当于辅节点发送给主控节点的数据传输状态信息包含两个信息，一个是ACK_SN，另一个是NACK_SN列表。
对于主控节点接收到该数据传输状态信息，对于序列号小于ACK_SN的所有PDU，除了显示罗列在NACK_SN列表中的数据包内容之外的所有PDCP  PDU，均认为传输成功，无需重传；而对于NACK_SN列表中的PDCP PDU，需要安排在其它路径的重传；在主控节点分配给辅节点的所有数据包内容中，序列号大于ACK_SN的所有PDCP PDU，认为均未传输，也需要安排在其它路径的传输。
一般来说，以上三种形式的数据传输状态信息一般适用于AM(确认模式)模式，ACK反馈也是指RLC层的状态报告中携带的显式确认。如果是UM(非确认模式)模式，则可以只反馈哪些数据包已经发送，哪些数据包没有发送，即下面的第四种形式。
(4)第四种形式
数据传输状态信息包括：进行了空口传输的数据包内容的序列号和/或未进行空口传输的数据包内容的序列号。
此时，主控节点可根据数据传输状态信息和分配给辅节点的数据包内容的信息，确定未进行空口传输的PDCP PDU，并传输这些未进行空口传输的PDCP PDU。
需要说明的是，这里所说的SN，既可以是PDCP PDU本身的SN，也可以是接口传输协议所对应的SN，例如GTP-U(User plane ofGPRS Tunneling Protocol，GPRS隧道协议用户面)协议的SN。无论采取哪种形式的SN，只要主控节点和辅节点之前约定好即可。
步骤304、主控节点根据所述数据传输状态信息确定待处理数据。
其中，待处理数据包括需要重传的数据包内容即重传数据包内容，以及需要传输的数据包内容即传输数据包内容。其中，需重传的数据包内容指的是辅节点进行了空口传输但未收到对端ACK确认的数据包内容；而需要传输的数据包内容，指的是未进行空口传输的数据包内容。
步骤305、主控节点根据所述链路异常指示信息为所述目标链路选择替代链路，在所述替代链路上处理所述目标链路对应的数据。
在此实施例中，主控节点具有自己的传输链路，当某条辅基站链路上报异常之后，主控节点可以安排相关的数据在自己的链路上进行传输或者重传，也可以安排在其他辅基站的链路上进行传输或者重传。
对于上述第一种形式，主控节点收到了这种形式的数据传输状态信息后， 可认为将所述第二类数据包内容和所述第三类数据包内容作为待处理数据。其中，第二类数据包内容需要重传，而第三类数据包内容是需要传输的。
对于上述第二种形式，主控节点将序列号位于SN1和SN2之间的PDCP PDU作为重传数据包内容，将列号大于SN2的PDCP PDU作为传输数据包内容。如果数据传输状态信息中还包括第四类数据包内容的序列号，那么重传数据包内容为除所述第四类数据包之外的数据包内容。
对于上述第三种形式，主控节点将NACK_SN列表中的PDCP PDU作为重传数据包内容；在主控节点分配给辅节点的所有数据包内容中，将序列号大于ACK_SN的所有PDCP PDU，作为所述传输数据包内容。
对于上述第四种形式，主控节点将未进行空口传输的数据包内容作为传输数据包内容。
步骤306、主控节点向所述辅节点发送状态上报确认消息。
步骤307、辅节点根据所述状态上报确认消息停止所述目标链路上数据的传输。
步骤308、当所述目标链路的链路状态信息满足预设的链路恢复条件时，辅节点向主控节点发送链路质量恢复指示信息。
当辅节点的目标链路状况满足了某些预配置的恢复条件，则向主节点上报链路质量恢复指示信息，通知主基站该链路可以进行正常传输。其中预配置的恢复条件，可以由RRC信令配置。例如可以是链路质量监测的结果满足一定的门限。并且为了避免误报，可以为链路质量监测的结果满足一定的门限且维持了一定的时间或者次数，则判断链路恢复。
相应的，主控节点接收辅节点发送的链路质量恢复指示信息。
步骤309、主控节点向所述辅节点发送链路恢复确认消息。
之后，主控节点恢复在目标链路传输数据。
在本公开实施例中，辅节点在上报了链路异常指示信息后，可以对目标链路进行复位。其中，复位可以发生在步骤307之后。也即，在停止数据传输的同时或者之后。或者，复位还可发生在步骤309之后。辅节点复位相关的状态信息，例如RLC/MAC/PHY所有状态复位，即将所述目标链路复位，利用复位后的所述目标链路进行数据传输。也即，从目标链路的初始状态开 始传输数据。
在上述过程中，根据对目标链路的监测结果，如果目标链路的链路状态满足重复上报条件时，再次向所述主控节点发送链路异常指示信息。例如，当目标链路进一步恶化，或者超过一定的条件还没有恢复时，可以由辅节点再次上报主控节点，之后主基站可以将该链路删除。当然，这也可以由主基站自行判断目标链路的链路状态是否进一步恶化或者超过一定的条件还未恢复，并将该链路删除。
由上面可以看出，在本公开实施例中，当目标链路发生链路异常时，辅节点可向主控节点发送链路异常指示信息，由主控节点根据该信息选择替代链路，并处理目标链路对应的数据。因此，利用本公开实施例的方案当目标链路发生异常时，可及时的在替代链路处理目标链路的数据，从而保证了数据传输的正常进行。
本公开的另一实施例应用于CU-DU架构中，且CU-DU之间的协议栈分离方式采取的是PDCP-RLC分离的架构，即PDCP作为集中协议栈，位于CU实体，RLC层及以下的协议栈分别位于各个DU。
在该架构中，CU-DU存在接口，用于传输用户数据和交互信息。CU进行集中控制，也是数据的集中锚点，UE的数据均需要通过CU节点与核心网或者外部网络进行交互。对于单个UE来说，可以与多个DU建立连接并通过其传输数据，数据最终会汇总于CU。在本架构中，CU-DU之间接口传递的数据内容也是PDCP PDU，也会有传输协议，例如GTP-U(GPRS Tunnelling Protocol-U)或者GRE(Generic Routing Encapsulation，通用路由封装)等。
在本实施例中，单个的传输链路，例如某个DU也会发生链路恶化的情况，例如高频段的遮挡或者闪断情况，造成某个DU的链路在一定时间内无法正常的传输，因此需要将该情况告知CU，以确保该UE的数据能够继续接续的传输，不会造成用户体验的暂时中断。过段时间之后，链路可能恢复，CU恢复在该DU的数据传输，或者CU判断该DU不再适合为UE服务，从而删除该链路。
在本实施例中，CU-DU交互的方式与图4所示的实施例中的主控节点-辅节点的方式类似。在本实施例中，主控该节点是CU实体，辅节点是DU 实体。
不同的是，在此实施例中，主控节点选择替代链路的方式不同。主基站具有自己的传输链路，当某条辅基站链路上报异常之后，主基站可以安排相关的数据在自己的链路上进行传输或者重传，也可以安排在其他辅基站的链路上进行传输或者重传。而对于CU节点来说，它仅仅是一个控制节点，并不一定存在真正的传输链路。当一条DU链路发生异常中断上报时，此时CU节点只能安排在其他DU链路进行传输和重传。另外，由于CU-DU之间存在一定的控制关系，因此CU对各个DU的链路情况可能有更好的掌握，便于选择最优路径完成传输和重传。
由上可以看出，在本公开实施例中，当目标链路发生链路异常时，辅节点可向主控节点发送链路异常指示信息，由主控节点根据该信息选择替代链路，并处理目标链路对应的数据。因此，利用本公开实施例的方案当目标链路发生异常时，可及时的在替代链路处理目标链路的数据，从而保证了数据传输的正常进行。
在本公开的再一实施例中，给出另一种CU-DU架构中的处理方式，即CU-DU之间的协议栈分离方式采取的是Higher RLC-Lower RLC分离的架构，即PDCP和Higher RLC作为集中协议栈，位于CU实体，Lower RLC层及以下的协议栈分别位于各个DU。其中Higher RLC完成RLC PDU和PDCP PDU的一一映射，并分配RLC SN，而lower RLC根据实时地MAC层提供的传输资源的大小，将适合尺寸的RLC PDU及RLC PDU分段顺序的发送到MAC层进行组包并传输。
在这种架构中，CU-DU接口传输的数据包内容为携带RLC SN的RLC PDU。并且这个接口也可以具有传输层协议，例如GTP-U或者GRE。
在本公开实施例中，CU-DU交互的方式与图4所示的实施例中的主控节点-辅节点的方式类似。在本实施例中，主控该节点是CU实体，辅节点是DU实体。在这种架构中，由于RLC的主要ARQ(Automatic Repeat reQuest，自动重传请求)功能位于CU，因此DU无法对数据包进行精准的ACK确认，只能基于HARQ的反馈判断是否传输成功。如果基于HARQ的最大传输是否成功进行ACK状态的确认，在本公开实施例中数据传输状态信息的形式与图 4所示的实施例中的四种形式相同。只是在本公开实施例中，数据内容包为RLC PDU。
在图4所示的实施例的数据传输状态信息的四种形式的基础上，在本公开实施例中，还可增加一种形式的数据传输状态信息。即，数据传输状态信息包括：进行了空口传输的数据包内容所对应的最大序列号，所述进行了空口传输的数据包内容包括：进行了空口传输的RLC PDU。该SN可以是RLC SN，或者PDCP SN，或者传输网络层GTP-U或者GRE协议的SN。
由上面可以看出，在本公开实施例中，当目标链路发生链路异常时，辅节点可向主控节点发送链路异常指示信息，由主控节点根据该信息选择替代链路，并处理目标链路对应的数据。因此，利用本公开实施例的方案当目标链路发生异常时，可及时的在替代链路处理目标链路的数据，从而保证了数据传输的正常进行。
