- the physical link (ie, the first communication link) between the base station controller and the base station controller, and since there is no need to install a wireless maintenance terminal on the base station, the cost is saved. Since there may be multiple neighboring cells, there may be multiple normal base stations corresponding to neighboring cells. If the RNC receives all the information reported by the normal base station and sends instructions to all normal base stations, it will inevitably increase unnecessary resource waste. Therefore, in a preferred implementation, the RNC selects a normal base station according to a predetermined rule and processes the fault information reported from the selected normal base station; the RNC sends an instruction to establish the second communication link to the faulty base station through the selected normal base station. . In this way, the processing efficiency can be effectively improved.

Therefore, after the normal base station reports the fault information to the RNC, the following processing procedure may also be included: If the normal base station does not receive the command within the first predetermined time period, the fault information is re-reported. In this way, the above problems can be effectively solved.

- the RNC after the RNC sends an instruction to establish a second communication link to the faulty base station through the selected normal base station, it may also The following processing procedure is included: when the RNC does not receive the access result information of the selected normal base station feedback within the second predetermined time period, the RNC resends the instruction to establish the second communication link.
- the RNC In order to enable the RNC to effectively identify the fault information reported by different base stations, so that the RNC selects one base station as the reference base station, that is, the normal base station in the second communication link (such as the normal base station 32 in FIG. 3), the subsequent processing is completed, and therefore, Before the normal base station reports the fault information to the RNC, the identifier of the normal base station under the RNC may also be added to the fault message.
- the foregoing instructions include but are not limited to: an access command of a user equipment (User Equipment, UE for short). In this way, the manner in which the faulty base station accesses the normal base station may adopt an access mode including, but not limited to, analog user equipment UE access.
- the foregoing fault information may include the following information: a keyword that identifies a broadcast abnormality information type, an identifier of the faulty base station under the RNC, and an alarm information of the faulty base station.
- the foregoing embodiment may include the following steps in a specific application: (1) the base station detects that the communication link between itself and the RNC is abnormal; (2) the base station wirelessly broadcasts the fault information to the neighboring cell through the radio frequency module; (3) RNC The other normal base stations under the jurisdiction receive the broadcast fault information; (4) the other normal base station reports the message to the RNC; (5) the RNC parses the broadcast information to report the base station fault alarm in the background, and delivers the faulty base station through the base station reporting the broadcast information.

- the other normal base station reports the message to the RNC. Before reporting, the base station receiving the broadcast message adds the identity of the base station under the RNC to the message body, and starts a timer waiting to receive the analog UE access instruction. 5. The RNC parses the broadcast information to report the base station failure alarm in the background, and sends the faulty base station to simulate the UE access instruction by the base station that reports the broadcast information.
- the RNC may send a stop report message to all normal base stations under its jurisdiction. For example, the RNC only receives the information sent by the normal base station received for the first time. And use it as a reference base station. Then, the RNC parses the report information, reports the faulty base station information contained in the message to the background, and reports the alarm to the base station as the remote maintenance reference base station, and sends an analog UE access command to the base station to start waiting for the base station to report the access result timer. 6.

图 1为根据本发明实施例的基站的远程维护方法流程图。 如图 1所示， 该方法包 括： 步骤 S102, 故障基站检测到自身与 RNC之间的第一通信链路异常时， 向邻近小 区广播故障信息； 步骤 S104， RNC所辖的与邻近小区对应的正常基站接收故障信息并将故障信息 上报给 RNC; 步骤 S106, 正常基站接收来自于 RNC的建立第二通信链路的指令， 并将该指令 发送给故障基站； 步骤 S108, 故障基站根据接收的来自于正常基站的上述指令接入正常基站， 与 RNC建立第二通信链路。 上述实施例， 由于在上述第一通信链路异常时， 建立了第二通信链路， 从而完成 对故障基站的维护， 达到了在上述第一通信链路异常时， 对基站维护不依赖于基站与 基站控制器之间的物理链路 （即第一通信链路） 目的， 并且由于不需要在基站上加装 无线维护终端， 节省了成本。 由于与上述邻近小区可能有多个， 与邻近小区对应的正常基站也可能有多个， 如 果 RNC接收所有正常基站上报的信息并向所有正常基站发送指令的话，势必会增加不 必要的资源浪费， 因此， 在优选实施过程中， RNC按预定规则选定一个正常基站并处 理来自于选定的正常基站上报的故障信息； RNC通过选定的正常基站向故障基站发送 建立第二通信链路的指令。 这样， 可以有效提高处理效率。 为实现上述目的， 在具体 应用时， 上述处理过程可以设置在步骤 S106之前， 即故障基站接收来自于 RNC的建 立第二通信链路的指令之前。 在具体应用过程中，可能会出现 RNC没有接收到或没有正常处理上述正常基站上 报的故障信息的情况， 正常基站无法得知上报故障信息是否成功。 因此， 在正常基站 将故障信息上报给 RNC之后，还可以包括以下处理过程： 正常基站在第一预定时间段 内未接收到指令， 则重新上报故障信息。 这样， 可以有效解决上述问题。 在具体应用过程中， 当故障基站接入正常基站异常时， 例如正常基站或故障基站 没有接收到指令或指令信息丢失等， RNC无法得知接入情况。为了有效避免上述问题， 在 RNC通过选定的正常基站向故障基站发送建立第二通信链路的指令之后，还可以包
括以下处理过程： RNC在第二预定时间段内未接收到选定的正常基站反馈的接入结果 信息时， 则重新发送建立第二通信链路的指令。 为了使 RNC有效识别不同基站上报的故障信息， 以便 RNC选定一个基站作为基 准基站， 即第二通信链路中的正常基站 （如图 3 中的正常基站 32)， 完成后续处理， 因此，在正常基站将故障信息上报给 RNC之前，还可以在故障消息中添加正常基站在 RNC下的标识。 在具体实施过程中， 上述指令包括但不限于： 模拟用户设备（User Equipment, 简 称为 UE)接入指令。这样， 故障基站接入正常基站的方式则可以采用包括但不限于模 拟用户设备 UE接入的接入方式。 在具体应用过程中， 上述故障信息可以包括以下信息： 标识广播异常信息类型的 关键字、 故障基站在 RNC下的标识、 故障基站的告警信息等。 上述实施例在具体应用时， 可以包括以下步骤： （1 )基站检测到自身与 RNC之间 通信链路异常； （2)基站以无线方式通过射频模块向邻近小区广播故障信息； (3 ) RNC 所辖的其他正常基站接收到广播的故障信息； （4) 其他正常基站将消息上报给 RNC; ( 5 ) RNC 解析广播信息给后台上报基站故障告警， 并通过上报广播信息的基站下发 故障基站模拟 UE接入指令； （6)故障基站收到模拟 UE接入指令， 以模拟 UE的方式 接入下发指令的基站， 以建立用于远程维护的第二通道。 为了更好地理解上述实施例， 以下结合具体实例和相关附图详细说明。 实例 1 本实例中， 在当前外场实际组网， 邻近小区相互覆盖， 为基站互相通信提供了前 提，相关技术中远程维护基站对基站的远程维护完全依赖基站与 RNC之间正常的通信 链路。当基站与 RNC之间通信链路发生故障时，故障基站向临近小区广播基站故障信 息， 临近小区的基站收到广播信息后上报 RNC， 通过 RNC下发指令， 故障基站模拟 UE接入正常基站所辖小区，这样后台维护经由正常基站可以实现对故障基站的远程维 护本实例以时分 -同步码分多址系统为背景阐述。对故障基站建立第二维护通道实施远 程维护的方法， 具体可以包括以下步骤： 一、 基站对自身与无线链路控制器 RNC之间通信链路状况检测。 对基站来说， 当检测到自身与 RNC之间接口异常时， 基站认定当前与 RNC之间 通信链路异常。
二、 基站通过射频天线向邻近小区广播故障信息。 基站通过射频天线广播基站异常信息， 该信息包含但不限于： 标识广播异常消息 类型的关键字、 该基站在 RNC下的唯一标识、 基站当前主要告警等。 三、 RNC所辖的其他正常基站接收到广播的故障信息。 正常工作的基站收到故障广播信息后， 解析消息， 判断消息类型是否是基站故障 广播消息， 如果属于， 按照建立第二通道的流程准备上报； 否则， 按照其他正常流程 进行处理。 四、 其他正常基站将消息上报给 RNC。 在上报之前，接收到广播消息的基站在消息体中添加基站在 RNC下的标识，并启 动等待接收模拟 UE接入指令的定时器。 五、 RNC解析广播信息给后台上报基站故障告警， 并通过上报广播信息的基站下 发故障基站模拟 UE接入指令。
RNC收到上报消息后， 为了减少 RNC与基站之间的无用通信， RNC可以向其所 辖的所有正常基站下发停止上报信息指令，例如 RNC只接收首次接收到的正常基站发 过来的信息， 并将其作为基准基站。然后 RNC解析上报信息， 将消息中包含的故障基 站信息向后台上报告警、记录上报基站作为远程维护基准基站， 向该基站下发模拟 UE 接入命令， 启动等待基站上报接入结果定时器。 六、 正常工作的基站对 RNC下发的模拟 UE命令处理。 远程维护基准基站收到该命令后， 关闭等待接收模拟 UE接入指令的定时器， 通 过射频天线下发该指令。 七、 故障基站收到该指令， 模拟 UE接入下发指令的基站， 建立用于远程维护基 站的第二通道。 故障基站收到模拟 UE接入命令后， 进入模拟 UE处理流程， 解析指令信息， 根 据指令信息接入指定的基站所辖小区。 当远程维护基准基站检测到模拟 UE接入后， 将接入结果上报 RNC， RNC收到后 结束等待基站上报接入结果定时器， 并对接入结果判断： 如果上报的接入结果为失败，
则再次下发模拟 UE接入指令， 设定等待基站上报接入结果定时器； 否则通知后台当 前故障基站已经接入可以远程维护。 八、 异常情况下的处理。 本实例中所指的异常情况指上述流程中定时器超时情况， 包括： 等待接收模拟 UE接入指令的定时器超时， 说明远程维护基准基站（即 RNC按预 定规则选定的基站，例如 RNC可以按接收的先后顺序确定基准基站，可以将首次接收 到故障信息所对应的正常基站作为基准基站)在规定时间内没有收到 RNC下发的模拟 UE接入命令，此时远程维护基准基站重新上报广播消息并重新设定接收模拟 UE接入 指令的定时器。 等待基站上报接入结果定时器超时，说明 RNC在规定时间内没有收到远程维护基 准基站上报的模拟 UE接入检测结果， 此时 RNC重新向远程维护基准基站下发模拟 UE接入指令并重新设定等待基站上报接入结果定时器。 实例 2 本实例以 TD网络为例进行说明。 图 2为根据本发明实例的基站的远程维护方法 流程示意图。 如图 2所示， 该方法包括： 步骤 S202, 故障基站 NodeB2检测到与 RNC之间链路异常时， 向邻近小区广播 基站 NodeB2的故障信息； 步骤 S204， RNC所辖的其他正常基站如 NodeBl接收到广播的故障信息， 并上报 所述故障信息给 RNC， 同时启动等待接收模拟 UE接入指令的定时器； 步骤 S206， RNC接收上述故障信息并解析广播信息， 向后台上报基站故障告警; 步骤 S208， RNC下发故障基站模拟 UE接入指令， 并启动等待基站上报接入结果 定时器； 步骤 S210， NodeBl接收上述指令， 并关闭等待接收模拟 UE接入指令的定时器， 同时下发模拟 UE接入指令给 NodeB2; 步骤 S212， NodeB2通过模拟 UE接入方式接入 NodeBl ; 步骤 S214， NodeBl向 RNC上报接入结果；
步骤 S216， RNC接收上述接入结果， 并关闭等待基站上报接入结果定时器， 同 时通知后台第二通道 （即第二通信链路） 建立， 最终实现基站的远程维护。 图 3为根据本发明实施例的基站的远程维护系统结构框图。 如图 3所示， 该系统 包括： 故障基站 30、 正常基站 32和 RNC 34。 其中， 故障基站 30， 通过正常基站 32与 RNC 34相连， 设置为在检测到自身与 RNC 34 之间的第一通信链路异常时， 向邻近小区广播故障信息； 以及根据接收的来自于正常 基站 32的建立第二通信链路的指令接入正常基站 32， 与 RNC建立第二通信链路； 正常基站 32，与邻近小区对应，设置为接收故障信息并将故障信息上报给 RNC 34； 以及接收来自于 RNC34 的所述建立第二通信链路的指令， 并将指令发送给故障基站 30。 在具体实施过程中， 如图 4所示， 故障基站 30可以包括： 检测模块 302，设置为检测故障基站 30与 RNC 34之间的第一通信链路是否异常; 广播模块 304， 与上述检测模块 302相连， 设置为在上述检测模块 302输出结果 为是的情况下， 向邻近小区广播故障信息； 第一接收模块 306， 设置为接收来自于正常基站 32发送过来的建立第二通信链路 的指令； 接入模块 308， 设置为根据指令接入正常基站 32， 与 RNC建立第二通信链路； 正常基站 32包括： 第二接收模块 322，设置为接收故障信息， 以及接收 RNC 34发送的建立第二通信 链路的指令； 第一发送模块 324， 与第二接收模块 322相连， 设置为将接收的故障信息上报给 RNC34以及将建立第二通信链路的指令发送给故障基站 30。 在优选实施过程中， 如图 4所示， RNC 34, 可以包括： 选择模块 342， 设置为按预定规则选定一个正常基站 32并处理来自于选定的正常 基站上报的故障信息；
