参阅图 2所示为本发明实施例中基于云计算的网元管理架构示意图。 该网 元管理架构包括至少一个网元 20, 接口管理服务实体 21 , 以及功能服务实体 22。 其中, 当包含多个网元 20时, 该多个网元 20可以为工作在同一种网络制 式下的网元, 也可以为工作在不同网络制式下的网元; 接口管理服务实体 21 , 用于接收网元发送的设备管理服务请求消息并转发至相应的功能服务实体
22, 以及将功能服务实体 22发送的设备管理服务响应消息转发至网元 20; 功 能服务实体 22, 用于响应于网元 20发送的设备管理服务请求消息, 为网元 20 提供设备管理服务请求消息所对应的服务。 上述接口管理服务实体 21和功能 服务实体 22可以为相互独立的设备, 也可以集成在在一个设备中, 以下以接 口管理服务实体 21和功能服务实体 22可以为相互独立的设备为例进行详细描 述。 具体的, 上述网元 20可以映射为现有通信系统中的通信网元设备, 如基 站、 基站控制器、 无线接入节点、 无线接入控制器等, 上述接口管理服务实 体 21可以映射为一个独立的服务器, 上述功能服务实体 22可以映射为现有通 信系统中的网元管理系统, 上述网元 20与接口管理服务实体 21之间可以通过 有线或者无线方式连接, 上述接口管理服务实体 21与功能服务实体 22可以通 过有线或者无线方式连接。 为了解决在 EMS管理网元的过程中, 存在硬件资源利用率低, 以及硬件 维护成本高的问题。 本发明实施例中, 当基于云计算的接口管理服务实体接 收到网元发送的设备管理服务请求消息后, 即根据该设备管理服务请求消息 中携带的该网元对应的网络制式标识以及请求服务类型, 调用基于云计算的 网元管理系统中的功能服务实体的服务功能生成服务请求响应消息; 将上述 服务请求响应消息发送至上述网络制式标识对应的网元。 釆用本发明技术方 案, 通过一个基于云计算的网元管理系统管理工作在不同制式下的多个网元, 从而避免了釆用多个网元管理系统管理工作在不同制式下的网元时造成的资 源浪费问题, 有效提高了硬件利用率。
下面结合附图对本发明优选的实施方式进行详细说明。
参阅图 3 所示, 在上述基于云计算的网元管理系统中, 本发明实施例进 行网元管理的过程为:
步骤 300: 接口管理服务实体接收网元发送的设备管理服务请求消息, 并 获取该设备管理服务请求消息中携带的该网元对应的网络制式标识, 以及根 据该网络制式标识所对应的协议格式, 对上述设备管理服务请求消息进行协 议转换。
本发明实施例中, 当网元需要针对某一项服务发起请求时, 即生成相应 的设备管理服务请求消息发送至基于云计算的网元管理系统, 网元管理系统 获取该设备管理服务请求消息中携带的网络制式标识。 其中, 网络制式标识 即为该网元所工作的网络制式(如 LTE网络制式, 3G网络制式)等的标识。
此外, 设备管理服务请求消息中还携带请求服务类型, 该请求服务类型 即包含 FM( Fault Management;故障管理)服务、 AM( Accouting Management; 计费管理)服务、 CM ( Configuration Management; 配置管理)服务、 PM ( Performance Management; 性能管理 )服务以及 SM ( Security Management; 安全管理)服务中的一种或多种。 其中, FM服务为故障管理服务, 提供包括 故障检测、 隔离以及纠正三方面的服务, 例如, 维护并检查错误日志, 接收 错误检测报告并作出响应, 跟踪、 辨认错误, 执行诊断测试, 纠正错误等; AM服务为计费管理服务,提供网络资源的使用管理记录服务, 以控制和监测 网络操作的费用和代价; CM为配置管理服务, 提供初始化并配置网络服务, 以使其提供网络服务, 以及实现某个特定功能或使网络性能达到最优, 例如, 设置开放系统中有关路由操作的参数, 管理对象和对象组名称, 初始化或关 闭对象, 根据要求收集系统当前状态信息, 获取系统重要变化信息, 更改系 统的配置等; PM为性能管理服务, 提供对系统资源的运行状况及通信效率等 系统性能的估算服务, 包括监视和分析被管网络及其所提供服务的性能机制, 收集分析有关被管网络当前状况的数据信息, 维持和分析性能日志等, 例如, 收集统计信息, 维护并检查系统状态日志, 确定自然和人工状况下系统的性 能, 改变系统操作模式以进行系统性能管理的操作; SM为安全管理服务, 提 供授权机制、 访问控制、 加密和加密关键字的管理服务, 以及对安全日志的 维护和检查服务, 例如, 创建、 删除、 控制安全服务和机制, 创建、 删除、 控制与安全相关信息的分布, 创建、 删除、 控制与安全相关事件的报告。
位于基于云计算的网元管理系统中可以包含五个功能服务实体, 分别对 应于上述五个请求服务类型, 即提供 FM服务的 FM功能服务实体、提供 AM 服务的 AM功能服务实体、 提供 CM服务的 CM功能服务实体、 提供 PM服 务的 PM功能服务实体和提供 SM服务的 SM功能服务实体,这些功能服务实 体的部署基于云计算, 即以云计算的服务(service )的形式出现, 物理实现上 无需集中到某一个硬件服务器上, 依赖于云计算的物理实现, 避免了将众多 功能集成在一个硬件服务器上时造成的一项服务请求量较大时, 影响其他服 务请求响应的问题, 有效提高了网元管理系统的可靠性。 并且, 在上述网元 管理系统中, 针对于一项或者多项功能的系统升级, 升级上述基于云计算的 一套网元管理系统中该功能对应的功能服务实体即可, 避免了多套网元管理 系统分别进行系统升级时造成的提高系统复杂度的问题, 简化了系统维护流 程, 降低了系统维护成本。
本发明实施例中, 由于上述设备管理服务请求消息对应的协议格式为与 网元所工作的网络制式对应的协议格式, 而不同网络制式下的网元所对应的 协议格式均不相同, 网元管理系统无法识别上述不同协议格式的设备管理服 务请求消息。 基于此问题, 通过网元管理系统中接口管理服务实体对工作在 不同网络制式下的网元发送的设备管理服务请求消息对应的协议格式进行区 换, 将该设备管理服务请求消息转换为统一协议格式的设备管理服务请求消 息, 以便后续对该统一协议格式的设备管理服务请求消息进行处理。 其中, 该接口管理服务实体为一个位于基于云计算的网元管理系统中的独立服务实 体, 即该接口管理服务实体并不集成在 FCAPS功能服务实体中; 而功能服务 实体为位于接口管理服务实体对端的服务实体, 接口管理服务实体和功能服 务实体通过有线或者无线方式实现通信。
进一步的, 参阅图 4所示, 对上述接口管理服务实体进行逻辑功能划分, 即将接口管理服务实体的功能模块划分为南向接口模块以及功能适配模块。 其中, 南向接口模块中包含多个南向接口, 每一个南向接口对应一种网络制 式, 该南向接口用于接收相应的网络制式网元发送的设备管理服务请求消息; 功能适配模块用于将上述不同南向接口接收的设备管理服务请求消息进行协 议转换; 此外, 功能适配模块还可以将功能服务实体发送的服务请求响应消 息进行协议转换, 即将统一协议格式的服务请求响应消息转换为不同网络制 式对应的协议格式的服务请求响应消息, 并将该服务请求响应消息发送至相 应的网络制式标识对应的南向接口。
对于由网元发送的设备管理服务请求消息, 接口管理服务实体的处理过 程为: 当接口管理服务实体接收到网元发送的设备管理服务请求消息时, 接 口管理服务实体中的南向接口模块即识别该设备管理服务请求消息携带的网 络制式标识, 并获取该网络制式标识对应的接口标识; 从接口管理服务实体 的南向接口模块中选定上述接口标识对应的南向接口, 并由该南向接口接收 上述设备管理服务请求消息, 以及对该设备管理服务请求消息进行解析, 将 解析后的设备管理服务请求消息发送至功能适配模块。 由该功能适配模块对 上述设备管理服务请求消息进行协议转换, 生成统一协议格式的设备管理服 务请求消息。
进一步的, 参阅图 5 所示, 还可以釆用另一种方法对上述接口管理服务 实体进行逻辑功能划分, 即划分南向接口模块和功能适配模块, 该南向接口 模块中包含多个南向接口, 其中, 每一个南向接口对应一种网络制式, 该南 向接口用于接收相应的网络制式网元发送的设备管理服务请求消息, 功能适 配模块包含多个功能适配子模块, 每一个功能适配子模块分别对应一个南向 接口, 该功能适配子模块用于将南向接口接收的设备管理服务请求消息转发 至功能服务实体, 或者将服务请求响应消息发送至相应的南向接口。
釆用上述技术方案, 在网元管理系统中添加接口管理服务实体, 对网元 发送的设备管理服务请求消息进行协议转换, 生成统一协议格式的设备管理 服务请求消息, 解决了一套网元管理系统无法识别工作在不同网络制式下的 网元发送的设备管理服务请求消息的问题, 便于后续对网元管理系统中网元 所请求的服务进行响应。
步骤 310:接口管理服务实体根据协议转换后的设备管理服务请求消息中 携带的服务类型, 向功能服务实体发送设备管理服务请求消息, 并接收该功 能服务实体根据上述设备管理服务请求消息生成并发送的服务请求响应消 息。
本发明实施例中, 接口管理服务实体根据设备管理服务请求消息中携带 的服务类型, 向位于基于云计算的网元管理系统内的功能服务实体发送统一 协议格式的设备管理服务请求消息, 即调用功能服务实体提供与上述服务类 型相对应的服务, 令网元管理系统中的功能服务实体响应上述设备管理服务 请求消息中的服务请求。
可选的, 当网元管理系统中包含多个功能服务实体时, 接口管理服务实 体可以根据设备管理服务请求消息中携带的服务类型, 向对应于该服务类型 的功能服务实体发送统一协议格式的设备管理服务请求消息, 从而调用上述 功能服务实体提供与上述服务类型相对应的服务, 令网元管理系统中的功能 服务实体响应上述设备管理服务请求消息中的服务请求。 可选的, 功能服务实体基于设备管理服务请求消息生成统一协议格式的 服务请求响应消息, 其中, 该服务请求响应消息中携带网元对应的网络制式 标识。
除此之外, 由于在不同网络制式下, 服务请求管理消息中携带的相同服 务请求关键字表示的含义可能不同, 例如, 在 LTE网络制式下, 告警管理服 务请求中告警码为 201表示告警 A, 而在 3G网络制式下, 告警管理服务请求 中告警码为 201表示告警 B, 若此时直接通过功能服务实体对上述设备管理 服务请求消息进行解析, 则将产生错误的服务请求响应消息。 基于上述技术 问题, 可以通过对功能服务实体进行逻辑划分, 具体为: 参阅图 6所示, 将 功能服务实体划分为网络制式适配模块以及通用功能适配模块, 其中, 网络 制式适配模块包含多个网络制式适配子模块, 每一个网络制式适配子模块对 应一种网络制式, 该网络制式适配子模块用于接收工作于相应的网络制式下 的网元发送的设备管理服务请求消息, 并解析该设备管理服务请求消息中携 带的服务请求关键字, 通用功能适配模块用于基于解析后的设备管理服务请 求消息生成服务请求响应消息, 并将该服务请求响应消息发送至相应的网络 制式适配子模块; 从功能服务实体的所有网络制式适配子模块中选定上述网 络制式标识对应的网络制式适配子模块, 通过该网络制式标识对应的网络制 式适配子模块对设备管理服务请求消息进行解析; 由功能服务实体的通用功 能适配模块基于解析后的设备管理服务请求消息生成服务请求响应消息, 其 中, 该服务请求响应消息中携带网络制式标识, 以便于后续对服务请求响应 消息的处理以及转发。 釆用上述技术方案, 通过接口管理服务实体根据网元 发送的设备管理服务请求消息调用位于基于云计算的网元管理系统内的功能 服务实体提供的相关服务, 即将多套网元管理系统提供的服务以及数据进行 统一管理, 从而实现了不同网络制式共享一套网元管理系统中的数据以及服 务, 有效降低了系统开发成本。
步骤 320: 接口管理服务实体将上述服务请求响应消息发送至上述网元。 本发明实施例中, 由于上述由功能服务实体生成的服务请求响应消息为 统一协议格式的消息, 即该服务请求响应消息仅能由功能服务实体识别, 而 不同网络制式下的网元对应的协议格式与上述统一协议格式不同, 因此, 若 直接将上述统一协议格式的服务请求响应消息发送至网元后, 网元并不能识 别该统一协议格式的服务请求响应消息。 基于此问题, 若釆用图 4所示的逻 辑划分方式时, 需要接口管理服务实体对上述统一协议格式的服务请求响应 消息进行协议转换, 具体为: 接口管理服务实体根据上述统一协议格式的服 务请求响应消息中携带的网络制式标识, 获取该网络制式标识对应的接口标 识, 将该统一协议格式的服务请求响应消息发送至上述接口标识对应的南向 接口; 接口管理服务实体通过该接口标识对应的南向接口将上述统一协议格 式的服务请求响应消息进行协议转换, 生成网络制式标识对应的协议格式的 服务请求响应消息, 并将该网络制式标识对应的协议格式的服务请求响应消 息发送至网元。
若釆用图 5和图 6所示的逻辑划分方式时, 则通过功能服务实体中的通 用功能适配模块对服务请求响应消息进行协议格式转换, 并由功能服务实体 中与服务请求响应消息中携带的网络制式标识对应的网络制式适配子模块将 该服务请求响应消息发送至基于云计算的网元管理系统内的接口管理服务实 体; 接口管理服务实体直接通过与上述网络制式标识对应的功能适配子模块 以及南向接口将服务请求响应消息发送至网元。
釆用上述技术方案, 避免了多个网络制式下的网元需要多套网元管理系 统管理时造成的繁忙网络对应的网元管理系统满负载运行, 而空闲网络对应 的网元管理系统低负载运行的现象, 仅通过一套基于云计算的网元管理系统 即可实现对多个网络制式下网元的管理, 对各个网络中的负载进行了统一管 理, 提高了系统性能; 并且, 通过一套网元管理系统实现原有多套网元管理 系统的功能, 避免了多套网元管理系统的功能重复问题, 有效降低了网元管 理的硬件成本以及对网元管理系统的硬件维护成本。
进一步的, 上述网元管理系统还可以根据客户端发送的指令对系统内的 部分功能进行管理, 从而便于用户对网元管理系统的日常维护工作。 具体为: 客户端向位于基于云计算的网元管理系统中的接口管理服务实体发送设备管 理指令, 接口管理服务实体接收该客户端发送的设备管理指令, 并获取该设 备管理指令中携带的权限信息, 其中, 该权限信息即为登录该云计算网元管 理系统的用户的管理权限; 若该权限信息满足预设管理权限条件, 则根据上 述修改指令对基于云计算的网元管理系统的平台级服务进行管理。 其中, 该 平台级服务包括操作系统、编程语言的运行环境、数据库和 Web服务器, EMS 提供商在此平台上部署和运行异构网络网元管理的应用, 即功能服务实体、 接口管理服务实体和 EMS数据库应用; 上述预设管理权限条件为用户拥有执 行相应操作时该用户应具备的管理权限, 可选的, 用户权限信息可以用用户 权限等级表示, 相应的, 预设管理权限条件为预设管理权限等级门限值。 例 如, 根据客户端发送的设备管理指令, 对云计算网元管理系统中的数据库进 行删除或者新建等操作。 进一步的, 若上述权限信息不满足预设管理权限条 件, 则该用户不能管理基于云计算的 EMS硬件资源和平台级服务, 仅能进行 有限的应用程序设置。
参阅图 7 所示, 网元管理系统中的功能服务实体提供网元请求的服务的 具体过程为:
步骤 700:功能服务实体接收接口管理服务实体发送的设备管理服务请求 消息。
本发明实施例中, 当网元需要针对某一项服务发起请求时, 即生成相应 的设备管理服务请求消息发送至功能服务实体, 功能服务实体获取该设备管 理服务请求消息中携带的网络制式标识。
步骤 710: 功能服务实体根据上述设备管理服务请求消息, 生成服务请求 响应消息, 并将该服务请求响应消息发送至接口管理服务实体, 令该接口管 理服务实体将上述服务请求响应消息发送至相应的网元。
本发明实施例中, 功能服务实体根据上述设备管理服务请求消息中携带 的网络制式标识, 获取该网络制式标识对应的网络制式适配子模块标识, 并 从功能服务实体的网络制式适配模块中包含的所有网络制式适配子模块中选 定上述网络制式适配子模块标识对应的网络制式适配子模块, 通过上述网络 制式标识对应的网络制式适配子模块对上述设备管理服务请求消息进行解 析, 获取该设备管理服务请求消息中携带的服务请求关键字, 其中, 每一种 网络制式标识对应一个网络制式适配子模块, 该网络制式适配子模块用于接 备管理服务请求消息进行解析, 网络制式适配模块为上述功能服务实体中的 逻辑模块; 并由上述功能服务实体的通用功能适配模块根据解析后的设备管 理服务请求消息生成服务请求响应消息, 其中, 通用功能适配模块用于基于 解析后的设备管理服务请求消息生成服务请求响应消息, 并将该服务请求响 应消息发送至相应的网络制式适配子模块, 该通用功能适配模块为上述功能 服务实体中的逻辑模块; 当所有网络制式下的服务请求关键字表示含义均相 同时, 上述功能服务实体可以仅包含通用功能适配模块, 通过功能服务实体 本地的通用功能适配模块对上述设备管理服务请求消息进行解析, 并基于解 析后的设备管理服务请求消息生成服务请求响应消息, 其中, 所有网络制式 标识均对应通用功能适配模块, 上述服务请求响应消息中携带网元对应的网 络制式标识。
下面结合具体的应用场景, 以釆用图 4 所示的逻辑划分方式, 网元管理 系统中包含五个功能服务实体以及接口管理服务实体, 网元工作的网络制式 包括 LTE网络制式, WLAN制式以及 3G网络制式为例, 详细介绍网元管理 的具体流程。
实现方式一
本发明实施例中,参阅图 8所示的基于云计算的网元管理系统,若网元 A (工作在 LTE网络制式下)请求的服务为计费管理服务, 则参阅图 9所示, 网元管理流程为:
步骤 900:接口管理服务实体经由与网络制式标识对应的南向接口接收网 元 A发送的设备管理服务请求消息。
本发明实施例中, 网络制式标识即为 LTE网络制式标识, 上述接口管理 服务实体位于基于云计算的网元管理系统中。
步骤 910:接口管理服务实体对上述设备管理服务请求消息进行解析获取 请求服务类型, 并根据网络制式标识对应的协议, 对解析后的设备管理服务 请求消息进行协议转换后, 将该设备管理服务请求消息发送至请求服务类型 对应的功能服务实体。
本发明实施例中, 由于网络制式标识为 LTE网络制式标识, 因此, 对设 备管理服务请求消息进行解析的南向接口即为 LTE南向接口; 而由于网元 A 请求的服务类型为计费管理服务, 因此, 接口管理服务实体的功能适配模块 将上述设备管理服务请求消息进行协议转换后发送至计费管理服务实体, 即 调用基于云计算的网元管理系统中的计费管理服务, 该计费管理服务位于基 于云计算的网元管理系统中。
步骤 920: 功能服务实体响应上述协议转换后的设备管理服务请求消息, 生成服务请求响应消息发送至接口管理服务实体。
本发明实施例中, 由于对于计费管理服务, 不同网络制式下的同一个服 务请求关键字所表示含义不存在不一致的问题, 因此, 无须对计费管理服务 实体进行进一步的逻辑功能划分。
步骤 930: 接口管理服务实体接收到该服务请求响应消息后, 即将该服务 请求响应消息转换为网络制式标识对应的协议格式的消息, 并将协议转换后 的服务请求响应消息通过网络制式标识对应的南向接口发送至网元 A。
本发明实施例中, 接口管理服务实体接收到该服务请求响应消息后, 即 将该服务请求响应消息转换为 LTE对应的协议格式的消息, 并将协议转换后 的服务请求响应消息通过 LTE南向接口发送至网元 A。
实现方式二
本发明实施例中,参阅图 10所示的网元管理系统,若网元 A(工作在 LTE 网络制式下)请求的服务为告警管理服务, 则参阅图 11所示, 网元管理流程 为:
步骤 1100: 接口管理服务实体经由与网络制式标识对应的南向接口接收 网元 A发送的设备管理服务请求消息。
本发明实施例中, 网络制式标识即为 LTE网络制式标识, 上述接口管理 服务实体位于基于云计算的网元管理系统中。
步骤 1110: 接口管理服务实体对上述设备管理服务请求消息进行解析获 取请求服务类型, 并根据网络制式标识对应的协议, 对解析后的设备管理服 务请求消息进行协议转换后, 将该设备管理服务请求消息发送至请求服务类 型对应的功能服务实体。
本发明实施例中, 由于网络制式标识为 LTE网络制式标识, 因此, 对设 备管理服务请求消息进行解析的南向接口即为 LTE南向接口; 而由于网元 A 请求的服务类型为告警管理服务, 因此, 功能适配模块将上述设备管理服务 请求消息进行协议转换后发送至云系统内的告警管理服务实体, 即调用告警 管理服务, 该告警管理服务实体位于基于云计算的网元管理系统中。 子模块接收上述协议转换后的设备管理服务请求消息, 并根据网络制式标识 对上述协议转换后的设备管理服务请求消息进行正确响应, 生成服务请求响 应消息发送至接口管理服务实体。
本发明实施例中, 由于对于告警管理服务, 不同网络制式下的同一个服 务请求关键字所表示含义存在不一致的问题, 因此, 需要对告警管理服务实 体进行进一步的逻辑功能划分。
步骤 1130: 接口管理服务实体接收到该服务请求响应消息后, 即将该服 务请求响应消息转换为网络制式标识对应的协议格式的消息, 并将协议转换 后的服务请求响应消息通过网络制式标识对应的南向接口发送至网元 A。
本发明实施例中, 相对于网元 A位于云端的接口管理服务实体接收到该 服务请求响应消息后, 即将该服务请求响应消息转换为 LTE对应的协议格式 的消息, 并将协议转换后的服务请求响应消息通过 LTE南向接口发送至网元 A。 基于上述技术方案,参阅图 12所示,本发明提供一种接口管理服务实体, 位于基于云计算的网元管理系统, 所述网元管理系统还包括网元, 以及功能 服务实体, 所述接口管理服务实体包括南向接口模块 120, 以及功能适配模块 121 , 其中:
