本实施例中, 如果多个属性均被设置, 即设置了多个属性的取值, 则 订阅条件为各属性对应的订阅条件的交集。 为使得本发明实施例提供的方 法更加清楚, 下面将以两种不同场景作为举例。
场景 1: 当 IRPManager发现某个区域(包括小区 Cdll、 Cell2和 Cdl3) 在 2010年 6月 5 日到 6月 7日之间发生了大量的"小区不可用"告警, 则可 以订阅小区 Cdll、 Cell2和 Cdl3在 2010年 6月 5 日到 6月 7 日之间的 5 分钟内发生频度超过 1000次的 RLF报告,用以辅助进行无线网络故障根源 分析。例如:可以将 RLF报告的订阅条件设置为:(AreaScope=Cdll or Cell2 or Cell3) and (TimeDuration is in between {00:00:00, 2010-06-05 } and
{23:59:59, 2010-06-07 }) and (OccurrenceFrequency = { 5 minutes, 1000})。 可以 理解的, 这里" = "的含义为"取值为", 后文不再赘述。
场景 2: IRPManager选择 Cdll和 Cell2创建周期性上报的立即
(Immediate) MDT任务后,希望同时获取整个立即 MDT过程中发生的 RLF 的 RLF报告, 用以进行 MDT报告和 RLF报告的后台关联处理。 例如: 可 以将 RLF报告的订阅条件设置为: (AreaScope=Cdll and Cell2) and
(TraceReference=TRl) ,其中 TR1为立即 MDT任务分配到的任务标识信息。 可选的, 本实施例中的 IRPManager可以通过多种方式向 IRPAgent设 置 RLF报告的订阅条件。
例如: 首先, IRPManager可以向 IRPAgent调用 CreateMO (创建管理 对象)操作, 用以请求 IRPAgent创建子网类或基站功能类的 RLF报告订阅 ( RLFReportingSubscription ) 子类; 然后, IRPManager则可以向 IRPAgent 调用设置管理对象属性 (SetMOAttributes) 操作, 用以请求 IRPAgent将创 建的 RLF报告订阅子类的属性设置为上述订阅条件对应的属性的取值。
再例如: IRPManager还可以向 IRPAgent调用订阅日志 (SubscribeLog) 操作,用以向 IRPAgent订阅上述 RLF报告,并将上述订阅日志操作的过滤 (Filter) 条件设置为上述订阅条件。 例如: 在订阅日志操作中的通知类別 ( NotificationCategories ) 参数, 增加一类反映 RLF事件的通知。
再例如: IRPManager还可以向 IRPAgent从信令跟踪任务集成参考点 (Trace IRP) 调用激活信令跟踪任务 (activateTraceJob) 操作, 用于向 IRPAgent请求生成信令跟踪任务, 该信令跟踪任务的任务类型 (Job Type) 为仅进行 RLF报告(RLF reporting only) , 上述激活信令跟踪任务操作的输 入参数为上述订阅条件对应的属性的取值。 其中, 上述 IRPManager调用的 操作具体为信令跟踪任务的激活信令跟踪任务操作, 该信令跟踪任务是 IRPManager的一个管理对象。可以理解的是: 与现有的信令跟踪任务类似, IRPAgent还可以进一步给上述生成的信令跟踪任务分配一个跟踪参考值 (Trace Reference) 和跟踪记录会话参考值 (Trace Recording Session

102、上述 IRPManager获得上述 IRPAgent发送的满足上述订阅条件的 RLF报告。 可选的, IRPManager可以通过多种方式获得上述 IRPAgent发送的满足 上述订阅条件的 RLF报告。
例如: IRPManager可以通过文件传输(File Transfer)方式获得 IRPAgent 发送的满足上述订阅条件的 RLF报告。 可选的, 具体过程为: IRPManager 可以接收 IRPAgent使用文件传输集成参考点的"通知文件准备好"功能提供 的通知, 并从指定的地址读取订阅结果文件, 该文件保存有满足上述订阅 条件的 RLF报告。
再例如: IRPManager可以通过通知日志方式获得 IRPAgent发送的满足 上述订阅条件的 RLF _¾告。 可选的, 具体过程为: IRPManager可以向 IRPAgent调用输出日志记录 (ExportLogRecords) 操作或获得日志记录
(GetLogRecords) 操作, 获得一个通知日志, 该通知日志保存有满足上述 订阅条件的 RLF报告;
再例如: IRPManager还可以通过信令跟踪任务跟踪结果 "¾告方式或 MDT任务跟踪结果 ^¾告方式获得 IRPAgent发送的满足上述订阅条件的 RLF报告。 在这种情况下, IRPManager可以将获得的 RLF报告存储在 IRPManager的跟踪采集实体 ( Trace Collection Entity , 筒称 TCE) 中。
本实施例中,通过 IRPManager向 IRPAgent设置 RLF ^良告的订阅条件, 使得 IRPManager能够获得 IRPAgent发送的满足上述订阅条件的 RLF报告, 能够避免现有技术中基站将从 UE获得的 RLF报告采用尽力而为的方式通 过 IRPAgent发送给 IRPManager, 从而减少 IRPManager和 IRPAgent之间 的信息传递负荷。 并且, 由于面向特定的管理应用订阅 RLF 报告, IRPManager无需处理冗余无用的 RLF报告, 降低了 IRPManager的处理负 担。 可选的, 本实施例中的 IRPAgent可以在 102之前获得满足上述订阅条 件的 RLF报告, 可参见图 2所示的实施例中的步骤 202及其举例, 此处不 再赘述。

再例如: IRPAgent还可以根据 IRPManager调用的订阅日志操作, 为 IRPManager订阅 RLF报告,并将订阅日志操作的过滤条件设置为上述订阅 条件。 例如: 在订阅日志操作中的通知类別参数, 增加一类反映 RLF事件 的通知 o
再例如: IRPAgent还可以根据 IRPManager调用的激活信令跟踪任务 (activateTraceJob) 操作, 为 IRPManager生成信令跟踪任务, 该信令跟踪 任务的任务类型 (Job Type) 为仅进行 1 1^ _¾告 (RLF reporting only) , 并 将上述订阅条件对应的属性的取值设置为上述激活信令跟踪任务操作的输 入参数。 其中, 可以理解的是: 与现有的信令跟踪任务类似, IRPAgent还 可以进一步给上述生成的信令跟踪任务分配一个跟踪参考值 (Trace
Reference) 和跟踪记录会话参考值 (Trace Recording Session Reference) , 其 中, 跟踪记录会话参考值可以缺省不进行设置。
202、上述 IRPAgent根据上述订阅条件,获得满足上述订阅条件的 RLF 报告。
可选的, IRPAgent根据上述订阅条件, 可以通过多种方式获得满足上 述订阅条件的 RLF报告。

203、上述 IRPAgent向上述 IRPManager发送满足上述订阅条件的 RLF 报告。
可选的, IRPAgent可以通过多种方式向 IRPManager发送满足上述订阅 条件的 RLF报告。
例如: IRPAgent可以通过文件传输方式向 IRPManager发送满足上述订 阅条件的 RLF报告。 也即, IRPAgent通过文件传输集成参考点将满足上述 订阅条件的 1 1^ _¾告发送给 IRPManager。 可选的, 具体过程为: IRPAgent 获得满足上述订阅条件的 RLF报告之后, 可以将上述满足上述订阅条件的 RLF报告保存在一个文件中,使用文件传输集成参考点的"通知文件准备好" 功能通知 IRPManager , IRPManager从指定的地址读取订阅结果文件。
再例如: IRPAgent可以通过通知日志方式向 IRPManager发送满足上述 订阅条件的 RLF报告。 也即, IRPAgent使用通知日志集成参考点的功能将 满足上述订阅条件的 RLF报告发送给 IRPManager。 可选的, 具体过程为: IRPAgent获得满足上述订阅条件的 RLF报告之后, 可以将上述满足上述订 阅条件的 RLF报告保存在一个通知日志中, 根据 IRPManager调用的输出 日志记录 (ExportLogRecords) 操作或获得日志记录 (GetLogRecords) 操 作, 将该通知日志发送给 IRPManager。 再例如: IRPAgent还可以通过信令跟踪任务跟踪结果良告方式或 MDT 任务跟踪结果报告方式向 IRPManager发送满足上述订阅条件的 RLF报告。 在这种情况下, IRPManager进一步将获得的 RLF ^¾告存储在 IRPManager 的 TCE中。
本实施例中, 通过 IRPAgent设置 IRPManager订阅的 RLF ^良告的订阅 条件, 使得 IRPAgent能够根据上述订阅条件, 获得满足上述订阅条件的 RLF _¾告, 并向 IRPManager发送, 能够避免现有技术中基站将从 UE获得 的 RLF报告采用尽力而为的方式通过 IRPAgent发送给 IRPManager, 从而 减少 IRPManager和 IRPAgent之间的信息传递负荷。 并且, 由于面向特定 的管理应用订阅 RLF报告, IRPManager无需处理冗余无用的 RLF报告, 降低了 IRPManager的处理负担。
