为使本发明的目的、 技术方案和优点更加清楚明白, 以下举实施例并 参照附图, 对本发明进一步详细说明。
图 2为本发明所描述的基于插件的电信网集中信令跟踪系统结构示意 图, 该系统包括集中网管系统(CMS, Centralized Managed System ), 网元 管理系统( NeMS , Net element Managed System ), 集中网管系统包含集中 信令跟踪子系统, 网元管理系统包含信令跟踪插件 (STP, Signal Trace Plug-in )。
其中, 集中信令跟踪子系统基于信令跟踪插件实现, 集中信令跟踪子 系统除提供信令跟踪的基本功能外, 还提供信令跟踪插件以及跟踪会话与 信令跟踪插件之间映射关系的管理和维护功能。 信令跟踪的基本功能包括: 跟踪会话管理; 信令码流消息的接收、 緩存和分发; 信令码流消息的概要 解码及呈现; 信令码流消息的详细解码及呈现等; 信令跟踪插件管理和维 护功能进一步包括: 信令跟踪插件的上载、 部署、 激活等管理功能, 其中 信令跟踪插件上载功能需要 NeMS配合完成。
本发明集中信令跟踪子系统内部架构示意图如图 3所示,
跟踪会话管理模块, 用于跟踪会话自身数据的维护和管理, 例如跟踪 会话状态信息的维护等;
跟踪框架模块, 用于信令跟踪的流程控制; 例如, 在跟踪会话发起后, 调用信令跟踪插件管理器的接口检测与网元设备对应的信令跟踪插件是否 已上载并部署到 CMS上, 若未上载和部署, 则指令信令跟踪插件管理器自 动执行所述信令跟踪插件的上载、 部署; 若已部署, 则指令信令跟踪插件 管理器激活对应的信令跟踪插件; 在接收到 NeMS上报的信令码流后, 调 用概要解码模块或详细解码模块对其进行解码处理等;
信令跟踪插件管理器, 用于完成信令跟踪插件的上载、 部署及激活; 概要解码模块, 用于调用与网元设备对应的信令跟踪插件的概要解码 接口对信令跟踪码流消息进行概要解码;
详细解码模块, 用于调用与网元设备对应的信令跟踪插件的详细解码 接口对信令跟踪码流消息进行详细解码。
本发明中信令跟踪插件是满足特定接口规范的一种可独立部署的功能 组件, 可在 NeMS或 CMS灵活部署和激活, 实现信令码流消息的 4既要解码 和详细解码处理。 这里所谓的特定接口规范, 是指针对 CMS和 NeMS信令 跟踪系统定制的、 需要信令跟踪插件遵循并实现的一套内部的概要解码和 详细解码接口。 集中信令跟踪子系统中, 各类网元的信令消息结构的差异, 以及网元升级前后版本间的兼容性问题, 主要都是体现在概要解码和详细 解码环节中。 本发明利用信令跟踪插件的灵活部署, 解决网元间信令消息 差异和升级时版本兼容性问题给集中信令跟踪功能带来的影响。
CMS系统通过 NeMS管理网元设备时, 利用插件上载功能将对应信令 跟踪插件获取到 CMS集中信令跟踪子系统中,并执行信令跟踪插件的部署 和激活流程。 当发起信令跟踪会话时, 利用信令跟踪插件进行信令码流消 息的概要解码和详细解码。信令跟踪插件从 NeMS系统上载到 CMS后, 按 照类型号和版本号在 CMS上分别部署和激活,从而有效地避免了不同信令 跟踪插件相互间的干扰和影响。 不同类型和版本的 NeMS提供的信令跟踪 插件也各不相同, CMS会分别上载。 此外, 信令跟踪插件可以同时在 CMS 和 NeMS分别部署, 从而避免信令跟踪逻辑的重复实现, 减少维护工作量, 节省研发投入, 提高研发效率。
如图 4所示, 本发明提供的基于插件的集中信令跟踪方法的基本流程 包括如下步骤:
步骤 401、 CMS 系统发起跟踪会话之前, 执行信令跟踪插件的检测和 上载;
CMS系统发起跟踪会话后, 跟踪框架模块自动执行跟踪会话指定网元 设备对应的跟踪插件的检测, 判断对应的信令跟踪插件是否已经上载, 若 还没有上载,则指令信令跟踪插件管理器自动向 NeMS下发 STP上载请求, NeMS接收到请求后, 回复携带 STP文件位置信息的应答消息, 信令跟踪 插件管理器根据应答消息中 STP文件位置信息从 NeMS上获取信令跟踪插 件文件并上载到集中信令跟踪子系统中; 若对应的信令跟踪插件已部署, 则指令信令跟踪插件管理器激活对应信令跟踪插件。
信令跟踪插件通常包括若干类文件, 比如配置文件、 解码接口文件、 解码动态链接库文件。 为了提高上载效率, 可将信令跟踪插件的所有组成 文件压缩成一个文件, 并通过 FTP协议下载到 CMS上。
步骤 402、 在信令跟踪插件上载完成后, 部署所述信令跟踪插件; 根据步骤 401所描述, 如果信令跟踪插件是新上载到 CMS上的, 则信 令跟踪插件管理器自动执行部署流程。 部署流程具体为: 将信令跟踪插件 的压缩文件分发到集中信令跟踪子系统的指定目录下, 解压出信令跟踪插 件包含的所有相关文件, 然后将解压出的各类文件注册到信令跟踪插件管 理器, 保证系统需要时可以正确访问到这些文件。
步骤 403、在信令跟踪插件部署完毕后, 激活跟踪会话指定网元所对应 的信令跟踪插件;
信令跟踪插件管理器根据当前设置的跟踪会话的类型和版本, 获取信 令跟踪插件相关文件的句柄, 读取文件内容, 为信令跟踪后续流程处理做 好准备。 具体激活动作包括: 读取配置文件的各配置项内容, 将解码相关 的动态链接库加载 (Load )到系统处理进程中, 将解码接口文件 (java类 压缩包文件)加载到 JVM ( Java Visual Machine )虚拟处理机中, 并初始化 对应接口实现实例对象。
步骤 404、 在激活信令跟踪插件后, CMS集中信令跟踪子系统执行集 中信令跟踪解码和呈现;
激活信令跟踪插件后, 集中信令跟踪子系统将跟踪会话下发到 NeMS, 再由后者分发到网元设备上。 网元设备上产生符合跟踪条件的信令码流消 息后,通过 NeMS上报到 CMS。 CMS集中信令跟踪子系统中的跟踪框架模 块接收到信令码流消息后, 首先调用概要解码模块对信令码流进行概要解 码, 概要解码模块将解码后的结果按序展示到跟踪结果界面上; 当需要查 看某个码流消息的详细信息时, 再调用详细解码模块对信令码流进行详细 解码, 详细解码模块将解码后的结果按序展示到跟踪结果界面上; 其中, 概要解码模块调用对应信令跟踪插件的概要解码接口对信令码流进行概要 解码, 详细解码模块调用对应信令跟踪插件的详细解码接口对信令码流进 行详细解码。 在解码过程中, 需要调用对应信令跟踪插件的动态链接库文 件提供的解码函数, 进行消息结构解析, 最后将解码结果按照一定的格式 呈现在系统界面上, 供用户查看。 本发明对于不同网元设备上报的信令跟 踪码流消息, 釆用不同的信令跟踪插件进行解码处理。 彼此之间相互独立, 互不关联和干扰, 从而有效实现不同网元设备的集中信令跟踪功能。
步骤 405、 网元(Ne )和 NeMS系统升级时, CMS自动执行信令跟踪 插件的升级检测、 上载及部署流程。
网元 Ne和 NeMS系统升级时, NeMS将系统升级信息通过信令消息通 知给 CMS, CMS再通过内部接口通知集中信令跟踪子系统, 集中信令跟踪 子系统收到通知消息后, 进行对应信令跟踪插件版本比对来判断信令跟踪 插件版本是否发生变更, 例如: 通过集中信令跟踪子系统中记录的 Ne 和 NeMS 的版本号与通知消息中携带的版本号比对来判断信令跟踪插件版本 是否发生变更。集中信令跟踪子系统中的跟踪框架模块首先检查 CMS上是 否已经上载过升级后的信令跟踪插件, 如果已经存在, 则不需要重复上载; 如果尚不存在, 则需要执行信令跟踪插件的上载流程, 信令跟踪插件的上 载流程参见步骤 401描述。 本发明中, CMS上的信令跟踪插件的升级检测 和上载流程都是系统自动完成, 无需人为干预, 极大提高了系统处理流程 的自主性和易用性。
本发明提供的基于插件的集中信令跟踪方法中, 信令跟踪插件上载流 程还包括: 首先在 CMS和 NeMS系统之间制定信令跟踪插件的接口规范, 接口规范明确后保持不变, 而且对于所有的网元类型都适用。其次在 NeMS 系统中生成对应版本的信令跟踪插件, 并随 NeMS 系统安装发布。 最后在 CMS中发起跟踪会话时, 依据跟踪会话对应的 NeMS标识, 构造信令跟踪 插件上载请求消息, 下发到 NeMS系统中。 NeMS系统接收到 STP上载请 求消息后, 生成信令跟踪插件的压缩文件的 FTP (文件传输协议) URL ( Uniform Resource Location )地址信息 ,并通过响应消息返回给 CMS系统。 CMS系统解析响应消息得到 FTP URL, 并据此从 NeMS上下载信令跟踪 插件的压缩文件。
本发明提供的基于插件的集中信令跟踪方法中, 信令跟踪插件部署流 程还包括: 将信令跟踪插件压缩文件分发到集中信令跟踪子系统指定目录 下并解压, 扫描解压结果目录, 识别出信令跟踪插件包括的配置文件 (例 如 XML格式或 ini格式的配置文件)、 解码接口文件(例如 java类压缩文 件)、 解码动态链接库(例如 DLL文件)。 然后将这些文件对应的文件句柄 信息注册到信令跟踪插件管理器中, 并和跟踪会话标识建立起映射关系, 以便在跟踪会话后续处理流程中可以访问到这些信令跟踪插件文件资源和 接口。
本发明提供的基于插件的集中信令跟踪方法中, 信令跟踪插件激活流 程还包括: CMS根据跟踪会话标识与信令跟踪插件文件的映射关系, 获取 对应信令跟踪插件文件所包含各类文件的文件句柄, 并将信令跟踪插件文 件所包含的各类文件加载到系统处理进程中, 等待解码模块的调用。 具体 为: CMS根据当前设置的跟踪会话标识, 从信令跟踪插件管理器中获取对 应文件的句柄, 读取配置文件中的配置项, 将解码相关的动态链接库加载 ( Load )到系统处理进程中, 将解码接口文件(java类 jar压缩文件)加载 到 java虚拟机( JVM, Java Visual Machine ) 中, 并实例化对应的 JAVA接 口实现类。
本发明提供的基于插件的集中信令跟踪方法中, 集中信令跟踪解码和 呈现流程还包括: 跟踪会话分发到网元设备上以后, 网元设备上产生符合 跟踪会话条件的信令码流消息后, 通过 NeMS上报到 CMS上。 CMS集中 信令跟踪子系统对码流消息进行緩存分发处理。 跟踪框架接收到跟踪码流 后, 依据跟踪会话标识与信令跟踪插件文件的映射关系调用对应的信令跟 踪插件接口, 对信令码流进行概要解码, 并将结果按照表格等形式呈现在 跟踪结果界面上。 当用户选中某个跟踪消息, 查看其详细信息时, 跟踪框 架模块调用对应信令跟踪插件的详细解码接口和 DLL库的解码函数, 对消 息码流进行详细解码, 并按解码结果的具体格式(可包括文本格式、 XML 格式、 树形结构格式等)呈现到结果界面。 详细解码完成后, 需要释放信 令跟踪插件对应的接口资源和 DLL资源。 对于不同网元设备上报的信令跟 踪码流消息, 跟踪框架釆用不同的信令跟踪插件接口进行解码处理。 彼此 之间相互独立, 互不关联和干扰, 从而实现不同网元设备的集中信令跟踪 和解码功能。 本发明提供的基于插件的集中信令跟踪方法中,当网元 Ne和 NeMS系 统升级时, CMS集中信令跟踪子系统处理流程还包括: 当 CMS集中网管 系统检测到所接入管理的 NeMS 系统发生升级或者打补丁等版本变更流程 时, 向 CMS集中信令跟踪子系统发送变更通知消息。 集中信令跟踪子系统 接收到通知后首先检查是否已经上载过升级后的信令跟踪插件。 如果已经 存在, 则不需要重复上载; 如果尚不存在, 则需要执行信令跟踪插件的上 载流程。 举例说明一下, CMS管理 Nel、 Ne2两个网元, 对应版本分别为 VI、 V2, 且 CMS上已经存在 VI和 V2两个版本的信令跟踪插件。 如果 Nel从 VI版本升级到 V2版本, Nel对应的信令跟踪插件也从 VI版本改 变为 V2版本。 此时由于 CMS上已经有 V2版本的信令跟踪插件, 所以不 需要从 Nel上再上载 V2版本的信令跟踪插件。 如果 Ne2从 V2升级到 V3 版本, 此时 CMS上尚未存在 V3版本的信令跟踪插件, 则需要从 Ne2上载 V3版本的信令跟踪插件。 由于本发明中, CMS上信令跟踪插件的升级检测 和上载流程都是系统自动完成, 无需人为干预, 极大提高了系统处理流程 的自主性和易用性。
图 5 为本发明基于插件的集中信令跟踪主要步骤细化处理流程图, 包 括如下步骤:
步骤 501、 CMS选定某个网元设备, 设置必要的跟踪过滤条件, 开始 发起跟踪会话;
步骤 502、跟踪框架模块检测当前跟踪会话指定网元所对应的信令跟踪 插件在 CMS上是否已经部署, 如果已经部署, 则转步骤 506, 否则转步骤 503;
判断对应的信令跟踪插件是否已部署的方法, 可通过判断对应的信令 跟踪插件是否已注册来判断, 由于信令跟踪插件的上载和部署在同一流程 中一次性完成, 因此, 可将判断对应的信令跟踪插件是否已部署作为判断 对应的信令跟踪插件是否上载的依据。
步骤 503 MS构造信令跟踪插件上载请求命令,下发到对应的 NeMS, 对应的 NeMS返回携带信令跟踪插件压缩文件的 FTP URL信息的应答响 应;
步骤 504、 CMS解析应答响应消息,获取信令跟踪插件压缩文件的 FTP
URL, 通过 FTP协议从 NeMS上载所述信令跟踪插件压缩文件;
步骤 505、 CMS上载信令跟踪插件的压缩文件后, 在集中信令跟踪子 系统中部署所述信令跟踪插件;
步骤 506、 CMS上的集中信令跟踪子系统激活跟踪会话所指定的网元 管理系统所对应的信令跟踪插件;
步骤 507、 所述信令跟踪插件激活成功后, CMS集中信令跟踪子系统 下发跟踪会话到对应 NeMS系统,并开始监听 NeMS上报的跟踪码流消息; 步骤 508、 集中信令跟踪子系统接收到跟踪码流消息后, 使用对应信令 跟踪插件的概要解码接口进行概要解码, 并显示解码结果;
步骤 509、 当指定某条跟踪码流进行详细信息查看时,使用对应信令跟 踪插件的详细解码接口进行解码, 并呈现解码结果;
解码完成后释放插件解码接口资源, 流程结束。
综上所述, 本发明具有以下一些技术效果:
( 1 )本发明利用插件机制实现集中信令跟踪功能。信令跟踪插件上载、 部署和激活, 是根据 CMS所管理网元的类型和版本分别进行的, 各插件之 间相互独立, 互不影响, 而且提供统一的信令跟踪接口。 彻底解决了电信 网管集中信令跟踪面临的网元设备类型和版本复杂多样、 集中信令跟踪研 发工作量庞大而复杂的问题,使得 CMS集中信令跟踪功能的实现方式简洁 而高效;
( 2 )本发明能够实现网元升级, 信令跟踪插件自动同步上载。 本发明 的网元设备和 NeMS升级时 CMS自动同步升级处理方法,可以保证升级网 元的信令跟踪插件上下级的一致性,从而保证 CMS集中信令跟踪功能在版 本变更情况下的正确性;
( 3 )本发明信令跟踪插件的上载、 部署、 激活以及升级处理都是自动 完成的。 本发明的信令跟踪插件上载和部署处理方法, 以及网元版本升级 时 CMS的同步处理, 都是系统自动完成的, 无需人为干预, 极大方便了工 程的实施和应用, 进一步提高了 CMS集中信令跟踪功能的自适应性;
( 4 )本发明的信令跟踪插件部署灵活。 本发明中信令跟踪插件可以分 别部署到 NeMS和 CMS两个系统中, 体现了一次开发多重部署的特点, 节 省研发资源投入, 一定程度上提高了电信网管系统研发效率。 本发明所涉 及的处理方法, 适当修改即可应用到其他网管系统中, 具备一定的普遍性。
以上所述仅为本发明的优选实施例而已, 并不用于限制本发明。 对于 电信网管集中信令跟踪领域, 本发明可以有各种变化和变更。 凡在本发明 的思想和原理之内, 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。
