网络管理系统(NMS )与网元管理系统(EMS )之间的接口称为北向接 口 (Itf-N ) 。 EMS主要完成国际电信联盟电信管理网 (ITU TMN )中的网元 管理层(EML )功能, 即完成一个或多个移动通信设备的管理功能, 通常不 同设备供应商之间的 EMS无法通用。 NMS主要完成 ITU TMN中的网络管 理层(NML )功能, 负责一个被管网络内所有网元的管理。对于被管网络(称 为子网) 内存在多个设备供应商的情况, 可以通过各自的 EMS 管理达到管 理整个子网的目的。
当移动通信设备发生故障时, 将产生相应的告警信息。 若 NMS订购了 相关的告警, 则当故障发生时, 告警信息将由 EMS 通过北向接口上报到 NMS。 而根据目前的告警处理方式, 当设备发生故障时, 产生的告警数量很 大, 需要通过北向接口传送的告警通知消息的数量很大, 对系统造成了很大 的负担。 同时, 目前上报给 NMS 的告警信息, 大多也不能提供明确的故障 根源信息和故障修复的操作指导, 不能给管理人员的故障定位和解决问题提 供快速、 准确的帮助, 所以需要一种方法, 以提高告警的效率, 在减少告警 数量的同时, 提供准确的故障定位。

以下通过实例更详细地描述本发明实施例所述的告警处理方法。
图 3 是一个逻辑功能模块上的一个可能生成并上报的告警相关的告警 路径的示意图。 如图 3所示,假设有一个逻辑功能模块 U1 , 其可能会产生事 件 E11 , 而 E11的产生, 可能因另两个逻辑功能模块 U2的事件 E21、 U3的 事件 E31的影响; 所以这里 U1在检测到 E11时可以生成并上 ^艮告警 Al l , 此告警为相关告警。 假设 U2在检测到事件 E21时可能上报的告警为 A21, U3在检测到事件 E31时可能上报的告警为 A31,且在 U3下面还有逻辑功能 模块 U4, 其在事件 E41时可能上报的告警为 A41, 则告警 All为如下告警 路径上的节点:
告警路径 1 (API) : A21->A11
告警路径 2 (AP2) : A41->A31->A11
所以, 对于逻辑功能模块 U1 来说, 其在告警关联信息存储模块中有对 应的一条信息, 用于预设该逻辑功能模块 U1, 在检测到事件 E11 时, 可能 生成并上报的告警是 All, 而 All是相关告警, 同时属于告警路径 1和 2, 在这两个告警路径上的层次分别是层次 2和层次 3。
这样, 当系统(网元)运行时, 如果逻辑功能模块 U1检测到事件 E11, 其告警处理过程如下:
当逻辑功能模块检测 U1到一个事件 Ell, U1向告警生成模块发送告警 生成请求,请求中包含逻辑功能模块的标识(U1 )、检测到的事件的标识(E11 ) 等参数;
告警生成模块根据收到的告警生成请求, 从告警关联信息存储模块获取 将生成的告警的类型信息, 预生成告警数据。 预生成的告警数据包括告警类 型 (All) 、 告警相关类型 (相关告警) 、 所属告警路径及层次( (1,2) , (2,3) )等;
告警生成模块根据预生成的告警的相关类型信息(相关告警)进行判断, 因该告警是相关告警, 则告警生成模块根据告警的所属告警路径及层次信息 ( (1,2) , (2,3) )查询告警存储模块, 看是否以及存在告警路径是 1、 告 警层次是 1, 或者告警路径是 2、 告警层次是 1或 2的告警, 如果有, 则不生 成和上报本告警; 如果没有, 则生成并上报本告警。
为了增加系统的灵活性, 便于运营商对不同厂商的设备的告警进行高效 管理, 网络管理系统可以通过北向接口对每个逻辑功能模块可上报的告警的 告警类型、 所属的告警路径及在告警路径上的层级等属性进行设置, 具体包 括: 网络管理系统通过北向接口给网元管理系统下发告警设置命令 , 命令至 少包括如下参数之一:
网元标识, 设置为选择一个或多个要进行设置的网元;
逻辑功能模块标识, 设置为选择要进行设置的逻辑功能模块; 告警类型, 设置为表示需要进行设置的告警类型;
告警相关类型, 设置为表示要设置的告警相关类型的值;
所属的告警路径及在此告警路径上的层级, 设置为表示被设置的告警类 型所属的告警路径及在此告警路径上的层级;
网元管理系统收到命令后, 将设置命令及参数分布下发给各个选中的网 元, 每个网元根据命令内容对相关告警类型进行设置;
完成设置后, 具体设置内容可以存放于一个告警类型信息列表, 该列表 根据告警分层处理的层次不同, 可以存放于逻辑功能模块、 网元、 网元管理 系统、 网络管理系统的一个或多个。
以上所述实施例仅为本发明的较佳实施例, 并非用于限定本发明实施例 的保护范围, 本领域的技术人员可以刻意对本发明实施例进行各种修改和变 型而不偏离本发明实施例的精神和范围。 这样, 倘若本发明实施例的这些修 改和变型属于本发明实施例权利要求及其等同技术的范围之内, 则本发明实 施例也意图包含这些修改和变型在内。
工业实用性
本发明实施例由于釆取以上所述的技术方案, 其包括以下优点: 减少了 上报告警的数量, 能够保证上报的告警是一个事件可能触发的所有告警中处 于最底层的告警, 有利于快速定位故障根源。
