具体实施方式
下面结合附图和实施例对本申请做进一步说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
移动通信系统的架构如图1所示，包括核心网(Core Network，CN)、基站子系统(Base Station Subsystem，BSS)、用户终端(User Equipment，UE)组成，其中基站子系统包括控制器(BSC/RNC)和基站(BTS/NodeB)。控制器和基站是一对多的关系，即一个控制器负责多个基站的工作。基站包括射频和基带部分，当前多采用射频分离的组网方式，基带和射频通过光纤方式进行通信，使得通信网络的组网方式更加的灵活。
现在以CDMA(Code Division Multiple Access，码分多址)无线通信系统为例对通讯系统进行详细的说明。请参考图2。
这样的通信系统可以使用不同的空中接口和/或物理层。例如，由通信系统使用的空中接口包括例如频分多址(DMA)、时分多址(TDMA)、码分多址(CDMA)和通用移动通信系统(UMTS)(如长期演进(LTE))、全球移动通信系统(GSM)等等。作为非限制性示例，下面的描述涉及CDMA通信系统，但是这样的教导同样适用于其它类型的系统。
参考图2，CDMA无线通信系统可以包括多个移动终端100、多个基站(BS)270、基站控制器(BSC)275和移动交换中心(MSC)280。MSC280被构造为与公共电话交换网络(PSTN)290形成接口。MSC280还被构造为与可以经由回程线路耦接到基站270的BSC275形成接口。回程线路可以根据若干己知的接口中的任一种来构造，所述接口包括例如E1/T1、ATM，IP、PPP、帧中继、HDSL(High-speed Digital Subscriber Line，高速率数字用户线路)、ADSL(Asymmetric Digital Subscriber Line，非对称数字用户线路)或xDSL(Digital Subscriber Line，数字用户线路)。将理解的是，如图3中所示的系统可以包括多个BSC2750。
每个BS270可以服务一个或多个分区(或区域)，由多向天线或指向特定方向的天线覆盖的每个分区放射状地远离BS270。或者，每个分区可以由用 于分集接收的两个或更多天线覆盖。每个BS270可以被构造为支持多个频率分配，并且每个频率分配具有特定频谱(例如，1.25MHz,5MHz等)。
分区与频率分配的交叉可以被称为CDMA信道。BS270也可以被称为基站收发器子系统(BTS)或者其它等效术语。在这样的情况下，术语"基站"可以用于笼统地表示单个BSC275和至少一个BS270。基站也可以被称为"蜂窝站"。或者，特定BS270的每个分区可以被称为多个蜂窝站。
如图2中所示，广播发射器(BT)295将广播信号发送给在系统内操作的移动终端100。如图1中所示的广播接收模块111被设置在移动终端100处以接收由BT295发送的广播信号。在图2中，示出了几个全球定位系统(GPS)卫星300。卫星300帮助定位多个移动终端100中的至少一个。
在图2中，描绘了多个卫星300，但是理解的是，可以利用任何数目的卫星获得有用的定位信息。如图1中所示的GPS模块115通常被构造为与卫星300配合以获得想要的定位信息。替代GPS跟踪技术或者在GPS跟踪技术之外，可以使用可以跟踪移动终端的位置的其它技术。另外，至少一个GPS卫星300可以选择性地或者额外地处理卫星DMB传输。
作为无线通信系统的一个典型操作，BS270接收来自多种移动终端100的反向链路信号。移动终端100通常参与通话、消息收发和其它类型的通信。特定基站270接收的每个反向链路信号被在特定BS270内进行处理。获得的数据被转发给相关的BSC275。BSC提供通话资源分配和包括BS270之间的软切换过程的协调的移动管理功能。BSC275还将接收到的数据路由到MSC280，其提供用于与PSTN290形成接口的额外的路由服务。类似地，PSTN290与MSC280形成接口，MSC与BSC275形成接口，并且BSC275相应地控制BS270以将正向链路信号发送到移动终端100。
基于上述通信系统，提出本申请的实施例。
实施例一
本发明实施例提出一种通讯容灾的方法。请参阅图3，方法包括：
步骤S310、实时监测本基站与上级网元的链路状态的翻转；
步骤S320、当监测到本基站与上级网元的链路状态从通路翻转为断路时，将本基站的射频单元的工作模式切换为移动终端模式；
步骤S330、获取中转基站的基站信息；
步骤S340、采用该移动终端模式与该中转基站建立通讯链接，由该中转基站对本基站与该上级网元之间的通讯消息进行转发。
具体的，本实施例的上级网元包括基站控制器。
在一个可选的方案中，对于步骤S310、实时监测本基站与该上级网元的链路状态，由于链路的状态是实时性的，因此，从通讯系统开始运行的时候即开始检查链路的运行情况。
具体的，本实施例中对于链路状态监测则是指检查链路状态翻转的情况，比如从通路变成断路或从断路变成通路。只有链路状态发生从通路翻转为断路的时候才执行步骤S320。
实际应用中，链路状态监测可以采取防抖机制，降低偶发的链路通断翻转导致的流程反复切换。比如，可以设置一定的阈值，当连续N次的检测中有P次链路翻转，则认为链路翻转；其中，N为大于0的正整数，P为大于0的正整数，N大于或等于P。
在一个可选的方案中，步骤S320、该将本基站的射频单元(RRU/RU)的工作模式切换为移动终端模式，包括：
将该射频单元的工作频点调整到移动终端的工作带宽，并以移动终端的方式进行工作，即把与中转站点进行通信的RRU/RU的工作频点设置与中转站点的使用的频点一致：
1、将与中转站点进行通信的本站点的RRU/RU的下行频点设置为中转站点使用下行频点所对应的上行频点；
2、将与中转站点进行通信的本站点的RRU/RU的上行频点设置为中转站点使用的下行频点。
在一个可选的方案中，步骤S330、获取中转基站的基站信息，包括：
步骤S331、判断是否有预存中转基站；
步骤S332、若有所述预存中转基站，在该预存中转基站中选择至少一个中转基站，并获取被选中的中转基站的基站信息；
步骤S333、若无所述预存中转基站，检测并判断相邻的且与本基站具有重叠覆盖区域的基站是否能够与本基站建立通讯链接；
步骤S334、若相邻的且与本基站具有重叠覆盖区域的基站能够与本基站建立通讯链接，则将能够与本基站建立通讯链接的基站作为备选中转基站并存储对应的基站信息；
步骤S335、在该备选中转基站中选择至少一个中转基站并获取被选择的中转基站的基站信息。
具体的，步骤S332，该在该预存中转基站中转基站中选择至少一个中转基站，并获取被选择的中转基站的基站信息时，可以根据所述预存的中转基站的质量和电平、业务量和业务能力、所述预存的中转基站中每个基站与上级网元的链路状态，选择至少一个中转基站并获取该中转基站的基站信息。比如：测量预存中转基站的电平和质量，挑选状态好基站作为中转站点；或者根据本基站的话务模型，选择多个中转基站；或者同时选择多个中转基站进行中转传输，以进行负荷分担；或者选择链路状态为直接同上级网元进行链接的中转基站等。
步骤S335，在所述备选中转基站中选择至少一个中转基站，并获取被选择的中转基站的基站信息时，可以根据所述备选的中转基站的质量和电平、业务量和业务能力、所述备选的中转基站中各基站与上级网元的链路状态，选择至少一个中转基站，并获取所述中转基站的基站信息。
具体的，在执行步骤S332时，可从预存中转基站中进行部分定点检测，检测本基站和预存中转基站之间的关系，比如和预存中转基站进行通信，检查其是否可作为中转基站。可选的，进行站点检测的时候，可部分开启RRU/RU进行检测，缩短检测时间，快速恢复系统业务。
具体的，在一个可选的方案中，可通过如下的方式获取并存储预存中转基站及对应的基站信息：
在该实时监测本基站与该上级网元的链路状态之前，预先存储该预存中转基站及对应的基站信息；和/或，
在该实时监测本基站与该上级网元的链路状态时，检测并判断相邻的基站与本基站具有重叠覆盖区域的基站是否能够与本基站建立通讯链接；将能够与本基站建立通讯链接的基站作为该预存中转基站并存储对应的基站信息。
实际应用中，可以选择在话务的较空闲时段进行检测。比如在夜间时，用户较少，此时，可以启动检测机制扫描可用于中转传输的站点。
在一个可选的方案中，步骤S340中采用该移动终端模式(即UE工作模式)与该中转基站建立通讯链接，是指本基站的RRU/RU采用移动终端模式，并非使用真正的移动终端进行工作，而是携带协商的协议进行通讯。
实际应用中直接和中转基站通信的RRU/RU可以同时启用UE工作模式和普通工作模式，即部分载频按照UE工作模式，部分载频按照普通的射频工作模式继续接收本基站覆盖的小区的话务。
在一个可选的方案中，该方法还包括：
接收其他基站发送的中转请求；
根据当前本基站与该上级网元的链路状态和/或预先设置的中转条件确定是否接受该中转请求；
若接受该中转请求则与发送该中转请求的基站建立通讯链接并为其分配中转资源。
在一个可选的方案中，该方法还包括：
当监测到本基站与该上层网元之间的链路状态从断路翻转为通路时，将本基站的射频单元的工作模式切换为正常模式；
采用该正常模式与该上级网元建立通讯链接。
本实施例的通讯容灾的方法，在基站与其上级网元(控制器/核心网)链路中断的时候，通过将其中部分射频的工作状态调整为移动终端的工作带宽，和邻近基站建立无线通讯连接，将由于传输不通而陷入瘫痪的基站和上级网 元重新建立连接，从而保证重要的基站能够正常工作。
实施例二
本发明实施例提供一种通讯容灾的方法。请参阅图4，方法流程包括：
步骤S410、通过配置的方式为每个基站配置预存中转基站，将预存中转基站使用的频点等基站信息存储在各基站的存储装置中；
需要说明的，实际应用中该步骤不是必须的。
步骤S420、实时监测本基站和上级网元的链路状态是否发生翻转，当监测到本基站与上级网元的链路状态从通路翻转为断路时，执行步骤S430，当监测到本基站与上级网元的链路状态从断路翻转为通路时，执行步骤S440；
步骤S430、判断从存储装置存储的预存中转基站中是否可以选择出可用的中转基站，如果无法从存储装置中获取到可用的中转基站，则执行步骤S431，如果可以从存储装置中获取到可用的中转基站，则执行步骤S432；
具体的，选择进行中转基站时可考虑如下因素：
1、选择质量和电平；
2、中转基站的业务量和业务能力；
3、有多个中转基站可选时根据本基站及多个中转基站的话务量确定是否需要同时选择多个中转基站进行中转传输，以进行负荷分担；
4、考虑中转基站本身的链路状态为直接同上级网元进行链接，而不是通过其他中转基站和上级网元链接。
步骤S431、在邻区的基站中检测可用的中转基站，将可用的中转基站及对应的基站信息存储到存储装置中。
实际应用中，也可以在本基站业务较少的时候自动检测可用的中转基站。
步骤S432、将本基站中部分RU的工作频点设置为与可用的中转基站使用的频点一致，并与可用的中转基站建立通讯链接，执行步骤S433。
具体的该步骤包括：
将与中转基站进行通信的RU的下行频点设置为中转基站使用的下行频 点所对应的上行频点，
将与中转基站进行通信的本站点的RU的上行频点设置为中转基站使用下行频点。
可选的，负责与中转站点进行通信的RU，可设置部分载频与中转基站通信，其他载频的RU正常吸收本小区的话务。
步骤S433、将本基站接收的上行信息发送给已建立链接的可用的中转基站，由中转基站传输到BSC；
步骤S434、接收中转基站转发的由BSC下行信息。
步骤S440、将RU的工作模式切换为正常工作模式，与BSC建立通讯链接。
具体的，本基站与BSC建立通讯链接之后，本基站接收的业务，都可以直接通过本基站的物理传输发送到BSC。
本实施例的通讯容灾的方法，在基站与其上级网元(控制器\核心网)链路中断的时候，通过将其中部分射频的工作状态调整为移动终端的工作带宽，和邻近基站建立无线通讯连接，将由于传输不通而陷入瘫痪的基站和上级网元重新建立连接，从而保证重要的基站能够正常工作。
实施例三

步骤S530、判断是否接受该中转请求，如果接受该中转请求，则执行步骤S540，如果不接受该中转请求，则执行步骤S550。
实际应用中本基站也可以将自身的链路状态通知请求站点，由请求站点 判断是否与本基站进行级联传输。
可选的：本基站在收到中转请求后，也可以与本基站的中转基站协商是否允许为请求站点进行级联传输。
S540、为发送中转请求的基站分配中转资源，并与其建立通讯链接。
可选的：本基站在分配中转资源的时候可以根据本基站的业务量以及本基站的中转基站分配给本基站的中转资源。
可选的：本基站可以同时接收多个请求站点的中转请求并分别为其分配资源进行中转传输。
实际应用中，如果本基站与多个中转基站建立了通讯链接，那么在为请求站点分配中转资源的时候可以将一个请求站点的中转资源分配到不同的中转基站上，以保证请求站点的业务不会因为出现单点故障导致失败。
S541：本站点将接收的业务信息，通过中转基站发送给上级网元，并处理中转基站传送的本站点的业务。
实际应用中，对于请求站点的业务信息，本基站可以根据分配资源的传输路径直接做转发处理，降低本基站的业务负荷。
具体的，实现容灾后的通讯链路示意图请参阅图6。
S550、向请求站点反馈拒绝中转请求的消息。
本实施例的通讯容灾的方法，在基站与其上级网元(控制器\核心网)链路中断的时候，通过将其中部分射频的工作状态调整为移动终端的工作带宽，和邻近基站建立无线通讯连接，将由于传输不通而陷入瘫痪的基站和上级网元重新建立连接，同时，在本实施例中即使本基站与上级网元的链路中断，仍可以作为其他基站的中转基站，从而保证重要的基站能够正常工作。

通讯单元40，设置为在该射频单元的工作模式切换为移动终端模式之后，采用该移动终端模式与该中转基站建立通讯链接。

具体的，本实施例中对于链路状态监测则是指检查链路状态翻转的情况，比如从通路变成断路或从断路变成通路。
具体的，监测单元10可以采取防抖机制对链路状态监测，降低偶发的链路通断翻转导致的流程反复切换。比如，可以设置一定的阈值，当连续N次的检测中有P次链路翻转，则认为链路翻转。

在本实施例中，选择模块，是设置为在根据该备选的中转基站的质量和电平、业务量和业务能力、该备选的中转基站中每个基站与上级网元的链路状态选择至少一个中转基站并获取该中转基站的基站信息；根据所述预存的中转基站的质量和电平、业务量和业务能力、所述预存的中转基站中各基站与上级网元的链路状态，选择至少一个中转基站并获取所述中转基站的基站信息。
具体的，选择模块在选择中转基站时，可从预存中转基站中进行部分定点检测，检测本基站和预存中转基站之间的关系，比如和预存中转基站进行通信，检查其是否可作为中转基站。可选的，进行站点检测的时候，可部分开启RRU/RU进行检测，缩短检测时间，快速恢复系统业务。
在一个可选的方案中，所述装置还包括：
存储单元60，设置为在监测单元10实时监测本基站与该上级网元的链路状态之前，预先存储该预存中转基站及对应的基站信息；和/或，
检测单元50，设置为在监测单元10监测本基站与该上级网元的链路状态时，检测并判断相邻的基站与本基站具有重叠覆盖区域的基站是否能够与本基站建立通讯链接；将能够与本基站建立通讯链接的基站作为该预存中转基站并存储对应的基站信息。
实际应用中，可以选择在话务的较空闲时段进行检测。比如在夜间时，用户较少，此时，可以启动检测机制扫描可用于中转传输的站点。
实际应用中，控制单元30将本基站的射频单元的工作模式切换为移动终端模式，是指本基站的RRU/RU采用移动终端模式，并非使用真正的移动终端进行工作，而是携带协商的协议进行通讯。
实际应用中直接和中转基站通信的RRU/RU可以同时启用UE工作模式和普通工作模式，即部分载频按照UE工作模式，部分载频按照普通的射频工作模式继续接收本基站覆盖的小区的话务。
在一个可选的方案中，如图8所示，该装置还包括：
接收单元70，设置为接收其他基站发送的中转请求；
该控制单元30，还设置为根据当前本基站与该上级网元的链路状态和/或预先设置的中转条件确定是否接受该中转请求，并在接受该中转请求时为发送该中转请求的基站分配中转资源；
该通讯单元40，还设置为该控制单元接受该中转请求时于与该发送中转请求的基站建立通讯链接。
在一个可选的方案中，该控制单元30，还设置为在监测到本基站与该上层网元之间的链路状态从断路翻转为通路时，将本基站的射频单元的工作模式切换为正常模式；
该通讯单元40，还设置为在射频单元的工作模式切换为正常模式之后，采用该正常模式与该上级网元建立通讯链接。
本实施例的通讯容灾的装置，在基站与其上级网元(控制器/核心网)链路中断的时候，通过将其中部分射频的工作状态调整为移动终端的工作带宽，和邻近基站建立无线通讯连接，将由于传输不通而陷入瘫痪的基站和上级网元重新建立连接，从而保证重要的基站能够正常工作。
