本发明的基本思想是： 首先， 将当前告警的告警检测点转换成路由点， 再根据预先保存的业务和路由点之间的对应关系， 找到所述路由点对应的 业务， 定位出当前告警的业务对象。
本发明的一种告警定位方法， 如图 1所示， 主要包括以下步骤： 步骤 101 : 接收携带有告警检测点的告警；
这里， 告警一般由通讯设备发出。 例如， 该通讯设备可以是 PTN网络 中的一个 PTN网元。
步骤 102: 将所接收告警中的告警检测点转换为路由点；
步骤 103: 根据已保存的路由点与业务的对应关系， 定位转换得到的路 由点对应的业务， 完成当前告警的定位。
这里， 将告警检测点转换为路由点， 具体可以是： 根据预先设定的映 射规则， 将所接收告警中的告警检测点转换为路由点。
其中， 所述方法还包括： 在当前业务路由信息发生变更时， 对所述告 警进行重定位。
具体地， 获取到当前业务的路由变更信息后， 对所保存的路由点与业 务的对应关系进行刷新； 之后， 根据刷新后的路由点与业务的对应关系， 对所述告警重新进行定位。
其中， 在对所述告警进行定位之前， 所述方法还可以包括： 获取当前 业务的路由信息， 生成路由点， 建立所生成路由点与业务的对应关系并保 存。 这里， 生成路由点后， 还可以从所生成的路由点中选取部分或全部的 路由点， 建立所选取路由点与业务的对应关系并保存。
相应地， 本发明还提供了一种告警定位装置， 主要包括： 告警管理模 块、 检测点转换模块、 告警定位模块， 其中， 告警管理模块， 用于在接收 到携带有告警检测点的告警时， 调用所述检测点转换模块； 在接收所述检 测点转换模块返回的转换结果时， 调用所述告警定位模块； 检测点转换模 块， 用于将所述告警检测点转换为路由点， 并将转换结果返回给所述告警 管理模块； 告警定位模块， 用于根据已保存的路由点与业务的对应关系， 定位所述转换结果中路由点对应的业务。
这里， 所述的告警检测点用于表示当前告警的位置地址， 例如， 分组 传送网（ PTN, Packet Transport Network )中的一个维护实体组终端点（ MEP, Maintenance Entity Group End Point ) , 路由点表示业务路由过程中的节点地 址，可以根据业务的路由信息直接生成。例如， T-MPLS隧道（ TMP, Transport MPLS Path )上的一个路由点， 即一个 T-MPLS隧道连接终端点（ TMPCTP, TMP Connection Termination Point )。
其中， 所述检测点转换模块， 可以根据预先设定的映射规则将所述告 警检测点转换为路由点。 这里， 所述检测点转换模块可以为一个或多个。
具体地， 预先设定的映射规则， 根据发出告警的通讯设备的特性确定。 映射规则对于特定的通信网络是固定的， 并因通信网络所釆用的通信技术 而异。 例如， 在 PTN中， TMPCTP就与基于其建立的 MEP具有对应关系， 作为告警检测点的 MEP可以按照这种对应关系转换为所基于的、作为路由 点的 TMPCTP。 具体的映射规则是本领域常用技术手段， 本发明不再赘述。
实际应用中， 会根据通讯设备的类型， 对应的映射规则不同， 会对应 不同类型的通讯设备， 设置不同的检测点转换模块。
其中， 所述告警管理模块在自身已保存的通讯设备类型与检测点转换 模块地址的对应关系中， 查找发起所述告警的通讯设备的类型所对应的检 测点转换模块地址， 根据查找到的检测点转换模块地址， 调用对应的检测 点转换模块。 这里， 所述通讯设备的类型包含在发送到告警管理模块的告 其中， 所述装置还可以包括： 对应关系模块， 用于保存所述路由点与 业务的对应关系。 具体地， 对应关系模块获取当前业务的路由信息， 生成 路由点， 建立所生成路由点与业务之间的对应关系并保存。 这里， 对应关 系模块还可以在所生成的路由点中选取部分或全部的路由点， 建立所选取 路由点与业务的对应关系并保存。
其中， 所述告警定位模块， 向所述对应关系模块查询所述路由点所对 应业务的信息， 并将查询到的业务信息返回给所述告警管理模块。
这里， 告警定位模块还用于在获取到当前业务的路由变更信息后， 调 用对应关系模块， 对所保存的路由点与业务的对应关系进行刷新； 之后， 告警定位模块通知所述告警管理模块， 对所述告警重新进行定位。
这里， 告警管理模块还用于接收所述告警定位模块返回的业务信息， 并显示给用户。
其中， 所述告警定位装置还可以包括： 对应关系模块， 用于保存路由 点与业务的对应关系。
所述告警定位模块， 具体用于， 从所述对应关系模块中查询到所述转 换结果中的路由点对应的业务。
这里， 所述告警定位模块， 还用于将包含有所查询到业务的定位结果 返回给所述告警管理模块。 所述告警管理模块， 还用于接收所述告警定位 模块返回的定位结果并显示。
实施例一
本发明告警定位装置的一种优选实施例， 如图 2所示， 包括四个模块： 告警管理模块、 告警定位模块、 对应关系模块和检测点转换模块。
其中， 告警管理模块为总调度模块， 负责在告警定位流程中调度其他 各模块。
告警定位模块， 向所述告警管理模块提供定位接口， 用于完成路由点 到端到端业务的定位； 此外， 还用于实时获取业务的路由变更信息， 在获 取到业务的路由变更信息后， 调用对应关系模块， 刷新路由点与业务的对 应关系表。
这里， 告警定位模块通过监听网管系统内用于配置业务信息的功能模 块广播的包含有业务当前路由变更信息的变更通知， 来实时获取业务的路 由变更信息。 其中， 业务的路由变更信息可以包含业务本身的标识信息如
ID、 友好名称等， 以及所述业务变更后的全部路由信息或者所述业务路由 信息中发生变更的路由信息。
对应关系模块， 在网管系统启动时， 负责读取全网端到端业务的路由 信息， 根据读取的路由信息， 生成路由点， 建立所生成路由点与业务之间 的对应关系表并保存； 向告警定位模块提供查询接口。 这里， 对应关系模 块还可以对生成的路由点筛选后， 再建立筛选后的路由点与业务之间的对 应关系表。
检测点转换模块， 向告警管理模块提供转换接口， 负责根据发出告警 的通讯设备的特性， 将告警中的告警检测点转换为业务的路由点。 由于检 测点转换模块与发起告警的通讯设备相关， 具有设备相关性， 因此， 可以 根据网管所管理的网络中通讯设备的类型设置多个， 每个检测点转换模块 负责某一类或多类通讯设备的告警检测点转换。
其中， 告警管理模块会在自身告警处理过程中调用检测点转换模块和 告警定位模块的相关接口， 告警定位模块会在定位过程中调用对应关系模 块的相关接口。 这里， 告警管理模块中可以保存检测点转换模块的地址与 通讯设备类型之间的对应关系表， 告警定位过程中， 告警管理模块根据发 起告警的通讯设备的类型， 调用对应的检测点转换模块。
在实际网管系统的部署中， 可以将告警定位模块和对应关系模块部署 在上层网管或网管系统中的上层子系统， 同时将检测点转换模块部署在下 层网管或网管系统中的下层子系统。 这样， 与设备相关性较强的检测点转 换模块就被下压到整个网管系统中比较靠下的位置， 从而保证了网管系统 上层的设备无关性， 有利于网管系统上层的稳定和版本升级。
告警管理模块由于涉及告警的整体处理流程， 因此在上层和下层中都 有部署。 实际应用中， 告警管理模块可以分为两部分， 分别部署在上层网 管或网管系统的上层子系统、 和下层网管或同一网管系统的下层子系统， 其中， 这两部分功能可以是完全相同的。 这两部分功能还可以是不同的。 例如， 部署在下层网管或网管系统的下层子系统中的告警管理模块， 用于 调用所述检测点转换模块； 部署在上层网管或网管系统的上层子系统中的 告警管理模块， 用于调用所述告警定位模块， 告警管理模块的两部分可以 共享信息。 或者， 部署在下层网管或网管系统的下层子系统中的告警管理 模块、 以及部署在上层网管或网管系统的上层子系统中的告警管理模块， 均可以用于调用所述检测点转换模块和告警定位模块。
实施例二
本实施例是本发明告警定位方法的一种优选实施例。
参照图 3所示， 本实施例中告警定位的过程， 通过图 2所示的告警定 位装置实现， 具体流程如下：
步骤 300: 对应关系模块生成路由点， 建立路由点与业务之间的对应关 系表， 并保存；
具体地， 网管系统启动时， 对应关系模块读取全网端到端业务的路由 信息， 根据所读取的路由信息， 生成路由点， 并选取其中的部分或全部路 由点， 在内存中建立所选取的路由点与业务的对应关系表。
这里， 所述对应关系表中包含有所选取的路由点、 以及业务的标识信 息， 如业务的 ID、 友好名称、 或者其他信息。
这里，选取路由点时， 可以根据实际告警的需要来进行。例如，在 PTN 中， 不会基于以太网的网络侧流点上报告警， 那么在选取路由点时， 就没 必要选取以太网的网络侧流点， 从而节省对内存空间的占用。
步骤 301 : 通讯设备将携带有告警检测点的告警上报到告警管理模块； 步骤 302: 告警管理模块接收所述告警， 调用检测点转换模块； 具体地， 告警管理模块部署在下层的部分接收到通讯设备上报的告警， 并调用所述通讯设备对应的检测点转换模块。
这里， 所述告警管理模块保存有通讯设备的标识信息与检测点转换模 块标识信息的对应关系， 例如， 通讯设备的类型与检测点转换模块地址的 对应关系， 所述告警中可以包含有发起告警的通讯设备的类型信息， 告警 管理模块查找到对应于所述告警中通讯设备类型的检测点转换模块的地 址， 并根据查找到的地址， 调用对应的检测点转换模块。
步骤 303: 检测点转换模块对所述告警检测点进行转换处理，得到对应 业务的路由点， 并将转换结果返回给所述告警管理模块；
具体地， 对应所述通讯设备的检测点转换模块对告警检测点进行转换 处理， 将告警检测点转换成业务的路由点， 并将转换得到的路由点添加在 告警事件中， 作为转换结果返回给所述告警管理模块。
步骤 304: 告警管理模块接收所述检测点转换模块返回的转换结果， 并 根据所述转换结果， 调用告警定位模块进行定位；
具体地， 告警管理模块部署在上层的部分读取步骤 303 中添加到告警 事件的路由点， 并根据所读取的路由点， 调用告警定位模块的定位接口， 向告警定位模块发送携带有所读取路由点的定位请求。
步骤 305~307：告警定位模块向对应关系模块查询所述路由点对应的业 务， 对应关系模块向告警定位模块返回查询结果， 告警定位模块接收所述 查询结果， 并向告警管理模块返回定位结果。
具体地， 告警定位模块接收到告警管理模块发送的定位请求后， 向对 应关系模块发送查询请求， 该查询请求中携带所述路由点； 对应关系模块 接收到所述查询请求后， 在自身保存的路由点与业务的对应关系表中， 查 找到对应于所述路由点的业务的信息， 并将包含有所查找到业务信息的查 询结果返回给告警定位模块， 告警定位模块接收所述查询结果， 向告警管 理模块返回包含有所查询到业务信息的定位结果。
步骤 308: 告警管理模块接收所述定位结果， 向用户显示所定位到的业 务的信息。
此外， 在业务的路由信息发生变更时， 本实施例的告警定位还可以包 括以下的告警重定位流程， 参照图 4所示， 具体包括以下步骤：
步骤 401~402： 告警定位模块在获取到业务的路由变更信息时，调用应 关系模块， 对应关系模块刷新自身保存的路由点与业务的对应关系表； 这里， 网管系统中用于配置业务信息的功能模块在业务的路由信息发 生变更时， 会向网管系统内所有模块广播业务变更通知， 该变更通知中包 含有业务的路由变更信息。 告警定位模块实时监听所述变更通知， 在监听 到变更通知后， 调用对应关系模块， 向对应关系模块发送刷新请求， 该刷 新请求中包含所述变更通知中包含的业务的路由变更信息， 对应关系模块 接收所述刷新请求， 并刷新路由点与业务的对应关系表。
这里， 对应关系模块刷新路由点与业务的对应关系表， 可以包括： 对 应关系模块根据所述刷新请求中包含的业务的路由变更信息， 删除无用的 路由点及该路由点与业务的对应关系信息， 和 /或， 增加路由点并添加该路 由点与业务的对应关系信息。
步骤 403~404： 对应关系模块向告警定位模块返回刷新成功消息，告警 定位模块接收所述刷新成功消息， 通知告警管理模块进行相关告警的重定 位。
这里， 对应关系模块在完成所述路由点与业务的对应关系表的刷新后， 向告警定位模块返回刷新成功消息， 该刷新成功消息可以是用于表示刷新 成功的指示消息。
告警定位模块接收到所述刷新成功消息后， 向告警管理模块发送告警 重定位通知， 通知告警管理模块进行告警重定位。 其中， 所述告警重定位 通知中可以包含有告警定位模块获取到的业务的路由变更信息、 或发生路 由变更的业务的标识信息，如发生业务变更的业务的 ID、友好名称等信息。
步骤 405~411： 告警管理模块调用检测点转换模块， 并重复执行步骤
303-308的告警定位过程， 进行相关告警的告警重定位。
具体地， 告警管理模块接收到告警定位模块发送的告警重定位通知后， 重新发起相关告警的定位， 定位过程与步骤 303~308完全相同， 这里的相 关告警可以包括告警管理模块中当前未定位的所有告警、 以及当前已定位、 与发生路由变更的业务相对应的告警。
实施例三
如图 5 所示， 某网管系统中的告警定位装置部署如下： 告警管理模块 分别两部分， 分别部署在网管系统的上层服务器中、 以及网管系统的下层 适配器中， 每个适配器中都会部署告警管理模块； 检测点转换模块部署在 下层的适配器中， 每个适配器中都会部署检测点转换模块； 告警定位模块 和对应关系模块都部署在上层的服务器中。其中，服务器与各适配器通过 F 接口连接。
某网管系统告警定位实施如下， 网管系统初启动时， 对应关系模块查 询全网业务的路由信息， 建立 hash表， 以业务的路由点为 key, 业务名称 为 value。
告警上报时， 首先告警管理模块调用各适配器中的检测点转换模块对 告警中的告警检测点进行转换， 检测点转换模块转换得到路由点， 并将转 换结果填写在告警事件中， 返回给告警管理模块； 然后， 告警管理模块调 用告警定位模块进行告警定位， 告警定位模块通过调用对应关系模块查询 所述 hash表， 得到路由点所对应业务的信息， 并将查询到的业务信息返回 给告警管理模块， 告警管理模块在交互界面向用户显示定位到的业务信息。
当业务的路由信息发生变更时， 告警定位模块监听到该变更， 令对应 关系模块发起路由点与业务之间对应关系表的刷新， 完成刷新后， 告警定 位模块通知告警管理模块进行告警重定位， 之后， 告警管理模块发起相关 告警的重新定位， 重新定位的具体过程与上述过程完全相同。 这里的相关 告警可以是与发生路由信息变更的业务相关的告警。
以上所述， 仅为本发明的较佳实施例而已， 并非用于限定本发明的保 护范围， 凡在本发明的精神和原则之内所作的任何修改、 等同替换和改进 等， 均应包含在本发明的保护范围之内。
