Description

实现对边界对象进行关联操作的方法和系统
技术领域
本发明涉及电信网络的网络管理技术, 尤其涉及一种利用子网的网元管理 系统实现对边界对象(BO )进行关联操作的方法和系统。 发明背景
图 1 为目前电信网络的主流管理模型示意图。 参见图 1, 目前电信网络主 流管理模型为分层结构,最底层为被管理的网元对象(ME, Managed Element ), ME 可以是设备、 设备间的连接、 物理资源、 逻辑资源等对象, 例如小区和链 路; 中间层为网'元管理系统( EMS , Element Management System ),在某些领域, 该 EMS又称为操作维护中心( OMC , Operation Maintenace Center ) , 用于直接 管理 ME, EMS是一种域管理器 (DM ), DM可以用于管理网元, 也可能包括 一些高层系统的功能, 每个 DM所管辖的 ME组成子网, 在子网中处于本子网 边缘、 同时又与相邻子网有关联的 ME称为边界对象(BO, Board Object ), 例 如边界对象可以为两个子网中的相邻小区, 也可以是相邻链路; 最上层为网络 管理系统( NMS, Network Management System ) , 用于管理下属的 DM和网络 级的资源, 在某些领域也可直接管理 ME。 DM与下层的 ME之间通过接口 1 进行通信, 与上层的 NM$ 'f-之间通过接口 2进行通信。
在图 1所示的电信 络中, 相关联的 BO组成的一个对象集称为 BO集, BO集中的 BO之间存在关联和互动关系, 简称相关。 一个 BO集中可以包含两 个或两个以上的相关 BO。 在同一个 BO集中, 一个 BO的信息发生改变, 则其 它 BO也需要对应地进行更新, 从而维持相关联的 BO之间的信息同步, 这种 更新同步的过程称为 BO关联操作。
图 2为无线网络的管理模型示意图。 该无线网络的管里模型是图 1所示电 信网络管理模型的一个具体实例。 参见图 2, 子网 Α中的小区 X与子网 Β中的 小区 Y为相互关联的 BO, —般称为相邻小区, 相邻小区的数据配置方面有非 常紧密的相关性, 一个小区配置数据的更改通常会影响其相邻小区的工作, 因 此其相邻小区的配置也需要同步调整。 如果相邻的两个小区是属于同一个 DM 管理, 则由 DM进行统一控制就可以实现关联操作。 但是现实的网络中, 通常 是多个厂商的设备在一个网络中运行, 每个厂商都通过自己的 DM对各自的网 元如小区进行管理。 因此, 在很多情况下, 相邻小区是受不同的 DM管理的, 例如图 2中小区 X由 DM A管理, 而小区 X的相关的小区 Y由 DM B管理。
由于相关 BO通常不属于一个 DM管理, 因此在现有的分层结构中, BO 关联操作主要通过 NMS来进行, 主要过程为:
将 BO集信息存储在 NMS中,且不同 BO之间的关联操作的属性信息也存 储在该 NMS中,一旦 BO集中的某个 BO的信息发生改变,则 NMS根据该 BO 与同 BO集中的其它 BO之间的关联属性信息对该 BO的改动信息进行分析, 确定该 BO的改动信息所导致的其相关 BO信息都有哪些改动,得到其相关 BO 的改动信息, 将该相关 BO的改动信息下发给该相关 BO所属的 DM, 此处称 该相关 BO所属的 DM为本地 DM的相关 DM , 由该相关 DM根据该 BO的改 动信息对该 BO直接进行同步修改。 所述关联属性信息可以是 BO信息与相关 BO信息的映射关系 , 其具体内容由相关 BO所属的 DM决定。
所述某个 BO的信息发生改变可能是因为 NMS维护人员的维护操作造成, 也可能是由于其所属 DM的数据同步造成, 即: 当某个 DM所辖的 BO信息发 生改变, 则该 DM发送同步通知给 NMS, 其中包括该 BO的标识信息以及发生 该 BO的改动信息, NMS收到同步通知后对相关 BO的信息进行同步。
但是, 由于现有技术中的 BO集信息以及各个相关 BO之间的关联属性信息 都存储在 NMS中, 而 DM中未存储 BO集信息, 同时也不能主动访问 NMS中的这 部分数据, 因此, 需要通过 NMS来统一调度多个 DM共同完成一次完整的关联 操作。 但是, 通常情况下, 由于 DM及其所管辖的网元都是同一厂商的设备, 因此 DM对自身所管辖的网元操作方面是最了解的, DM拥有强大的针对所有 ME的配置能力, 一个 BO随其它 BO信息改变而改变的关联属性信息一般都已经 详细地设置在该 BO所属的 DM中。 而现有技术中的方案为了实现关联操作, 需 要在 NMS上重复设置每个 DM的 BO关联属性信息, 并且根据这些信息通知相关 DM完成一个关联操作。 这样, 在 NMS上的很多功能就和 DM上的功能类似或者 重复, 浪费了建设成本。
另外, 由于现有技术是利用 DM和 NMS间的上下级接口方式进行关联操 作, 所以网络资源配置的有效性低、 工作效率低。 并且, DM无法自主地对其 所辖的 BO进行关联操作, 因此降低了 DM的智能化程度。 发明内容
有鉴于此, 本发明的主要目的在于提供一种实现对 BO进行关联操作的方 法, 能够由 DM直接完成关联操作, 以节约建设成本。
本发明的另一目的在于提供一种实现对 BO进行关联操作的系统, 以实现 不需 NMS的参与, 由 DM来完成关联操作, 节约建设成本。
为达到上述目的, 本发明的技术方案具体是这样实现的:
一种实现对边界对象 BO进行关联操作的方法,
本地 DM从 BO集存储单元中获取 BO集信息,得到与自身 BO相关的 BO 所属的相关 DM的信息;
根据所述相关 DM的信息, 本地 DM通过与所述相关 DM间的平行接口, 获取对方的 BO信息, 并进行 BO的关联操作。
所述 BO集存储单元中的 BO集信息包括:互为相关的两个或两个以上 BO 的标识信息、 以及互为相关的 BO所属 DM的标识信息。
所述本地 DM从 BO集存储单元中获取 BO集信息, 得到与自身 BO相关 的 BO所属的相关 DM的信息具体为:
本地 DM向 BO集存储单元发送携带本地 DM标识的 BO信息请求消息; 所述 BO集存储单元获得与该本地 DM相关的 BO集信息, 并将所述 BO 集信息返回给该本地 DM。
该方法进一步包括: 当所述 BO集存储单元中的 BO集信息有更新时, 则 向该更新的 BO集信息的相关 DM下发携带有所更新 BO集信息的更新通知, 相关 DM收到更新通知后对自身保存的 BO集信息进行更新。

以下参照附图和具体实施例对本发明的技术方案进行详细的说明。
本发明的核心技术方案为:一种实现对边界对象 BO进行关联操作的方法, 适用于利用域管理器 DM对子网进行管理的电信网络, 包括:
将 BO集信息存储在指定的 BO集存储单元中, 本地 DM从该 BO集存储 单元中查询 BO集信息, 得到与自身 BO相关的 BO所属的 DM;
本地 DM与所述查询到的相关 DM建立平行接口;
本地 DM和所述相关 DM通过该两者之间的平行接口获取对方的 BO信息, 并进行 BO信息的关联操作。
本发明所述的方法适用于各种电信网络, 如无线、 宽带、 传输、 IP等各种 种类的电信网络。
为了使各种 DM设备都可以访问识别 BO集中的信息, 本发明提出了标准 的 BO集信息的存储方式。 BO集的存储内容请参见表 1 :
Figure imgf000008_0001
表 1
如上述表 1所示, 一个 B0集中包括的信息为: 该 B0集的编号、 该 B0 集内 BO的数目、 每一个 BO的标识以及该 B0所属 DM的标识。 一个 B0集 内 B0的数目至少为两个, 且所有的 B0都相关联。
上述 BO信息可以由独立的系统如全网规划系统、或者是 NMS网管系统产 生, 形成批量数据, 用于转储到其它系统中使用。 本发明中有两种存储和访问 BO信息的机制能够实现在 DM层面的有效共 享
第一种机制: 所述的 BO集存储单元, 也可以称为 BO信息中心, 该 BO 集存储单元设置为一个独立的存储设备, 所有相关 DM的 BO集信息都存储在 该独立的 BO集存储单元中。
第二种机制: 为每个 DM设置所配套的 BO集存储单元, 用于存储该 DM 的 BO集信息。
当 BO集存储单元为一个独立的存储设备时, 可以将其设置为一个单独的 设备, 也可以和集中管理器联合设置在一起。其中, 集中管理器, 用于接收 DM 的注册信息并记录, 且向 DM返回用来建立平行接口的相关 BO所属 DM的接 入点信息和安全认证信息;
针对上述这几种情况, 以下分三个具体实施例进行说明。
图 3A为本发明第一实施例的结构示意图。 参见图 3A, 假设第一实施例的 BO集存储单元为一独立的存储设备,且该 BO集存储单元与集中管理器分别作 为独立的设备, 与 BO集存储单元连接的所有 DM的 BO集信息都输入存储在 该 BO集存储单元中。 BO集存储单元中包括至少一个 BO集信息, 每一个 BO 集信息的内容请参见表 1所示。 DM1和 DMx为相关的 DM, 为了在两个相关 的 DM之间进行关联操作, 需要在这两个 DM之间建立平行接口, 即接口 3。
图 3B为本发明第一实施例实现关联操作的流程图。 参见图 3B, 这里, 假 设本地 DM为 DM1 , 其它 DM的处理过程与 DM1的处理过程相同; 远端 BO 所属 DM为 DMx, 且此处称这些远端 BO所属的 DM为本地 DM的相关 DM。 该流程包括:
步骤 301 : 将本网中与所述 BO集中管理设备相连的所有 DM的 BO信息 都输入存储到 BO集存储单元中。
步骤 302: 本网中每一个 DM启动后, 都向集中管理器发送注册请求, 其 中包括: 本 DM的标识; 本 DM的接入点信息即本 DM的 IP地址和本 DM建 立平行接口使用的端口号; 以及建立平行接口所需的安全认证信息, 例如令牌 等。
步骤 303: 集中管理设备收到 DM的注册请求后, 存储该注册请求的内容, 并向 DM返回是否注册成功的注册应答消息。
由于每个 DM启动后都会向集中管理器上进行注册, 因此, 集中管理器就 记录了所有已注册的 DM的详细信息, 比如 DM的标识、 IP地址、 建立平行接 口使用的端口号、 安全认证的方式等等。
当集中管理器向一个 DM返回注册应答消息时,可以将其它已经注册的 DM 的注册信息携带在该注册应答消息中发给该 DM, 携带的信息至少包括已注册 D1V [的标识、 IP地址、 建立平行接口的端口号、 安全认证信息。
步骤 304:本网中的每个 DM在启动后,向 BO集存储单元发送携带该 DM 标识的 BO信息请求消息。
步骤 305: BO集存储单元收到 BO信息请求消息后, 查询与该消息中的 DM标识相关的 BO集信息, 即查询每个 BO集中是否包括该 DM标识, 如果 是, 则该 BO集与该 DM相关, 将与该 DM相关的 BO集信息携带在 BO信息 应答消息中发给发起 BO信息请求的 DM。
当 BO集存储单元中的 BO集信息有更新时, 则向与该更新的 BO集信息 相关的 DM下发携带有更新 BO集信息的更新通知, 相关 DM收到更新通知后 对自身的 BO集信息进行更新。
步骤 306: 本地 DM收到与本地 DM相关的 BO集信息后, 从该 BO集信 息中提取所有与本地 DM相关的 BO (即本 DM的远端 BO )所属 DM的标识 信息。
相关 DM的地址、 建立平行接口的端口号以及安全认证信息可以从集中管 理器返回的 DM注册应答消息中获取。
如果此时集中管理器没有向 DM1返回其它 DM的注册信息, 则 DM1还需 向该集中管理器发送一个查询消息, 该查询消息中携带 DM1 的相关 DM的标 识, 集中管理器收到该查询消息后向 DM1返回相关 DM的注册信息, 包括相 关 DM的标识、 IP地址、 建立平行接口的端口号以及安全认证信息。 步骤 !307: DM1 向 DMx发送平行接口建立请求消息, 该平行接口建立请 求消息的目的地址和端口为该 DMx的 IP地址和建立平行接口的端口号, 并携 带该 DMx的安全认证信息。
步骤 308: 收到平行接口建立请求消息的 DMx验证该请求消息中的安全认 证信息, 验证通过则建立平行接口即接口 3 , 并向 DM1返回携带平行接口成功 建立信息的平行接口建立应答消息, 否则, 返回携带失败信息的平行接口建立 应答消息。
此处所述的平行接口从物理上与图 1中所示的现有技术的上下接口, 即接 口 1和接口 2没有本质区别, 只是传递的信息内容不同。
步骤 309: .至此, DM1和其相关 DMx间建立了平行接口, DM1和 DMx 通过二者间的平行接口获取对方的 BO信息, 并进行 BO信息的关联操作。 此 处以从 DM1到其相关 DMx的关联操作为例具体说明关联操作的过程:
DM1判断本地的 BO信息是否发生改动, 如果是, 则查询 BO集信息, 确 定与该 BO相关的 BO以及该相关 BO所属的相关 DM, 此处为 DMx的标识; 将该 BO的改动信息通过平行接口发送给 DMx, 该 DMx对收到的改动信息进 行分析, 确定本 DMx内与收到的 BO信息相关的 BO需要进行怎样改动, 该过 程本领域技术人员熟知, 具体怎样分析需根据每个 DM的预定的相关 BO的关 联属性, 例如相关 BO信息的映射关系等确定。 最后, 该 DMx按照确定后的改 动信息对本 DMx内的相关 BO信息进行同步更新。
上述流程中, DM1与所有与其相关的 DMx之间建立了固定的平行接口, 以用于进行关联操作。 本发明也可以只在 DM1 的 BO信息发生改变时, 查询 BO集存储单元该发生改变的 BO所属的 BO集信息, 得到与该发生改变的 BO 相关的 BO所属的 DM, 然后, 再向集中管理器查询这些相关 DM的 IP地址、 端口号、 安全认证信息, 利用这些信息与这些相关 DM建立平行接口, 同样可 以利用这种方式建立的平行接口进行关联操作, 这种平行接口可以称为临时平 行接口。 可以在关联操作结束后, 将该临时平行接口拆除。
图 4A为本发明第二实施例的结构示意图。 参见图 4A, 第二实施例的 BO 集存储单元为一独立的存储设备, 且将该 BO集存储单元和集中管理器联合设 置于一个设备中,此处将该集成了 BO集存储单元和集中管理器的设备称为 BO 集信息集中管理设备 41 , 并将此时与该 BO集存储单元连接的所有 DM的 BO 集信息都输入存储在该 BO集存储单元中。每一个 BO集信息的内容请参见表 1 所示。 DM1和 DMx为两个相关的 DM, 为了在两个相关的 DM之间进行关联 操作, 需要在这两个 DM之间建立平行接口, 即接口 3。
另外,所述的集中管理器和独立的 BO集存储单元还可以与 MS置于一个 设备中。
图 4B为本发明第二实施例实现关联操作的流程图。 参见图 4B, 该流程与 图 3B所示的流程基本相同, 只是图 4B中的集中管理器和 BO集存储单元合并 为一个 BO信息集中管理设备 41 , 所有与集中管理器和 BO集存储单元相关的 操作都通过该 BO信息集中管理设备进行即可。
与第一实施例类似, 第二实施例中也可只在相关 DM之间建立临时平行接 口, 以进行关联操作。
图 5A为本发明第三实施例的结构示意图。 参见图 5A, 第三实施例在电信 网络中的每个 DM中设置 BO集存储单元, 将与本 DM相关的 BO集信息存储 在本 DM的 BO集存储单元中。每一个 BO集信息的内容请参见表 1所示。 DM1 和 DMx为两个相关的 DM, 为了在两个相关的 DM之间进行关联操作,需要在 这两个 DM之间建立平行接口, 即接口 3。 所述集中管理器作为独立的设备单 独设置。
图 5B为本发明第三实施例实现关联操作的流程图。 参见图 5B, 这罩, 假 设本地 DM为 DM1, 其它 DM的处理过程与 DM1的处理过程相同; 远端 BO 所属 DM为 DMx, 且此处称这些远端 BO所属的 DM为本地 DM的相关 DM。 该流程包括:
步骤 501 : 在每个 DM即 DM1和 DMx中, 将与各自相关的 BO集信息存 储在自身中即该 DM中的 BO集存储单元中。
步骤 502: 本地 DM即 DM1从自身的 BO集存储单元中提取所有远端 BO 所属 DM即 DMx的标识信息。
步骤 503: DM1向集中管理器发送注册请求, 其中包括: 本 DM1的标识、 本 DM1的 IP地址、 本 DM1建立平行接口使用的端口号、 以及建立平行接口 所需的安全认证信息如令牌等。
步骤 504: 集中管理器收到 DM1的注册请求后, 存储该注册请求携带的信 息, 并向 DM1 返回是否注册成功的注册应答消息, 该注册应答消息中携带其 它已经注册的 DM的注册信息, 其中至少包括已注册 DM的标识、 IP地址、 建 立平行接口的端口号、 安全认证信息。
DM1从集中管理器返回的注册应答消息中可以获得 DMx的注册信息。 当然, 此处也可在 DM1发送的注册请求中携带 DMx的标识信息, 集中管 理器收到注册请求后, 只返回该 DMx的注册信息。
上述步骤 501至步骤 504在每个 DM开机启动后都要执行, 从而保证集中 管理器上记录了所有 DM的注册信息。
步骤 505: DM1向相关的 DMx发送平行接口建立请求消息, 该平行接口 建立请求消息的目的地址和端口为该 DMx的 IP地址和建立平行接口的端口号, 并携带该 DMx的安全认证信息。
步骤 506:收到平行接口建立请求消息的 DMx验证该请求消息中携带的安 全认证信息, 验证通过则建立平行接口, 向本地 DM1 返回携带平行接口成功 建立信息的平行接口建立应答消息, 否则, 返回携带失败信息的平行接口建立 应答消息。
步驟 507: 至此, 本地 DM1和其相关 DMx间建立了平行接口, 本地 DM1 和其相关 DMx通过该两者之间的平行接口获取对方的 BO信息,并进行 BO信 息的关联操作。
与第一实施例类似, 第三实施例中也可只在相关 DM之间建立临时平行接 口, 以进行关联操作。
图 6为使用本发明所述方法后电信网络的管理模型示意图。 参见图 6, 与 现有技术的管理模型相比, 本发明一个显著的变化是两个相关 DM之间可以建 立一个信息交互的平行接口, 即接口 3 , DM1能够通过这个平行接口获取 DM2 所管理的 BO的当前信息, 反之亦然。 这样相关 DM之间就可直接进行联动操 作。 在这种模型下, NMS的功能可以简化, 现有 NMS中进行关联操作的功能 可以下移到 DM中,使 DM更加智能化, 减少了功能模块的重复, 节约了成本, 使得整个系统的效率得到了提升。
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做的任何修改、 等同替换、 改进等, 均应 包含在本发明的保护范围之内。
