附图概述 图 1为本发明实施例的实现语音信令跟踪的系统的示意图; 图 2为本发明实施例的实现语音信令跟踪的方法的流程图; 图 3为语音呼叫建立的流程图。
本发明的较佳实施方式 为了更好地理解本发明, 下面结合附图和具体实施例对本发明作进一步 地描述。 需要说明的是, 在不冲突的情况下, 本申请中的实施例及实施例中 的特征可以相互任意组合。 图 1为本发明实施例的实现语音信令跟踪的系统的示意图,如图 1所示, 远端用户可以通过远程登录连接上本发明实施例的实现语音信令跟踪的装 置, 控制本实施例的装置进行语音信令的跟踪。 本实施例的实现语音信令跟踪的装置可以是 ONU设备, 还可以是支持 远程登录的需要从远端查看语音信令报文的设备, 如带语音业务的数字用户 线路( Digital Subscriber Line, DSL )设备。 如图 1所示, 本发明实施例的实现语音信令跟踪的装置可以包括远程传 送模块和语音模块, 由于语音模块与远程传送模块分属不同的软件模块, 两 者的数据传送需要专门的通讯支撑来支持, 以保证在数据量大的情况下数据 不丟失、 且不重复。 实际应用中, 这里专门的通讯支撑可以由 3部分组成, 一是不同软件进 程之间的通讯, 二是不同单板之间的通讯, 三是为了保证数据传送准确性而 做的优化。 远程传送模块可以釆用 telnet协议来实现远程登录, telnet协议是标准的 提供远程登录功能的应用, 是 Internet上最广泛的应用之一。 目前大部分的 ONU设备以及 DSL设备都实现了 telnet功能。信令跟踪的数据通过 telnet协 议打包发送给远端用户, 对于其他 telnet应用而言, 信令跟踪功能对 telnet 协议部分没有特殊的要求。 本实施例的远程传送模块除了釆用 telnet协议外, 还可以釆用安全外壳 协议( Secure Shell Protocol, SSH )、 以及简单网络管理协议( Simple Net work Management Protocol, SNMP )等能够提供远程登录功能的协议。 本实施例的远程传送模块能够为远程用户提供命令行接口 ( Command Line Interface, CLI )用户界面。 远端用户连接上远程传送模块后, 可以在 CLI用户界面上输入跟踪语音 信令的控制命令等。 远程传送模块接收到远端用户输入的控制命令后, 打开 跟踪语音信令开关, 即将预设的相应的跟踪语音信令开关状态置为开启, 然 后将该跟踪信令开关的状态信息发送给正在与远端软交换(Softswitch, SS ) 进行数据交互的语音模块 由于语音信令内容繁多, 在远程传送模块上可以预先设置跟踪语音信令 的总开关、 各种跟踪语音信令范围的子开关, 例如, 各种语音相关协议的跟 踪子开关及其跟踪内容范围子开关等, 这样用户可以只关注重点语音信令内 容, 有选择地进行语音信令的跟踪, 能够减轻对系统造成的负载。 开关设置示例如下:
Globol— Trace enable/disable 信令跟踪总开关
H248— Trace enable/disable H248协议跟踪开关
H248— Trace— Level 1..3 H248协议跟踪内容范围
MGCP— Trace enable/disable MGCP协议跟踪开关 MGCP— Trace— Level 1..3 MGCP协议跟踪内容范围
SLIC Trace enable/disable SLIC模块跟踪开关 SLIC— Trace— Level 1..3 SLIC模块跟踪内容范围
执行过程中远程传送模块可以根据远端用户输入的控制命令, 先打开信 令跟踪总开关, 再根据需要逐一打开控制跟踪信令内容范围的子开关, 再将 这些开关对应的控制指令传送给语音模块。 语音模块接收到控制指令后, 记录下各开关的状态, 然后接收到控制指 令后, 检查接收到的所述跟踪语音信令开关的状态信息是否为开启, 若是, 则记录指定跟踪的语音信令内容; 若为关闭, 则不记录指定跟踪的语音信令 内容。
具体地, 语音模块检查跟踪语音信令的总开关状态信息和指定相应的跟 踪语音信令范围的子开关状态信息是否均为开启, 若是则记录指定跟踪的语 音信令内容; 若检查跟踪语音信令的总开关状态信息和指定相应的跟踪语音 信令范围的子开关状态信息之一为关闭,则不记录指定跟踪的语音信令内容。 语音模块记录所指定跟踪的语音信令内容, 可以通过通信支持提供的接 口有序地将记录下的语音信令内容发送给远程传送模块, 最后通过远程传送 模块发送给远端用户, 最终实现远端用户查看语音信令跟踪内容的功能。
由于, 在跟踪语音信令的过程, 远端用户随时会停止相关语音信令的跟 踪, 语音模块在向远程传送模块传送语音信令内容之前, 还需要实时检查相 应的信令跟踪开关的状态, 在检查相应开关状态为开的情况下, 才将相关的 语音信令内容传送给远程传送模块。
图 2为本发明实施例的实现语音信令跟踪的方法的流程图, 本实施例以 ONU设备为例进行说明, 如图 2所示, 本实施例的方法可以包括下面步骤: 步骤 201 : 远端用户通过 telnet连接入 ONU设备, 通过 CLI用户界面请 求语音信令跟踪, 指定跟踪的语音信令内容。 步骤 202: ONU设备收到指定跟踪的语音信令内容的控制命令后, 记录 指定跟踪的语音信令内容; 具体地, ONU设备接收到远端用户的控制命令后,打开语音信令跟踪总 开关, 进一步打开用户指定需指定跟踪的语音信令范围的子开关, 并记录下 这些开关的状态。并且, ONU设备开始监控指定跟踪的语音信令相应的各种 事件, 一旦有需要监控的事件发生, 即进入信令跟踪状态, 记录该事件, 比 如用户摘机事件、 或挂机事件。 本发明实施例引入了信令跟踪的分级机制, 在方便用户获取关键信息的 同时, 可以减轻了开启信令跟踪功能而对设备带来的负荷。 在步骤 202中, ONU设备根据所述控制指令将预设的相应的跟踪语音信 令开关状态置为开启; 检查所述跟踪语音信令开关的状态信息是否为开启, 若是, 则记录指定跟踪记录的语音信令内容; 若不是, 不记录指定跟踪记录 的语音信令内容。 在步骤 202中, ONU设备进一步地根据第一控制指令将预设的跟踪语音 信令总开关的状态置为开启, 根据第二控制指令将相应的跟踪语音信令范围 子开关的状态置为开启; 检查跟踪语音信令的总开关状态信息和指定相应的 跟踪语音信令范围的子开关状态信息是否均为开启, 若是则记录指定跟踪的 语音信令内容; 若检查跟踪语音信令的总开关状态信息和指定相应的跟踪语 音信令范围的子开关状态信息之一为关闭, 则不记录指定跟踪的语音信令内
由于语音信令跟踪的内容比较多, 如果全部打开, 会对用户数据查看带 来困难, 对系统性能也有一些影响, 所以程序按开关模块来划分信令跟踪的 内容, 如上文的开关示例, 默认关闭所有开关模块。 实际应用中, 远端用户 需要指定需指定跟踪的语音信令内容。
步骤 203: ONU设备将记录的指定跟踪的语音信令内容发送给远端用户。 进一步地, ONU设备实时地检查信令跟踪的总开关及当前跟踪的语音信 令相应开关的状态, 在相关开关都处于开启状态的情况, 将语音信令内容发 送给远端用户, 实现语音信令的跟踪。 本发明实施例直接利用了具有语音业务的设备(例如 ONU设备) 维护 经常使用的远程传输命令,例如 telnet协议命令,在 telnet协议上实现了语音 信令跟踪, 用户不需要在故障现场, 在远端即可进行信令跟踪, 不依赖软交 换, 不需要额外安装软件。 远端用户可以通过 Procomm Plus等 telnet工具可以方便快捷的进行数据 查找、 打印、 抓屏、 以及自动保存等功能。 功能强大而且不需要额外开发, 并节省了人力。
图 3为语音呼叫建立的流程图, 媒体网关 (Media Gateway, MG)1和 MG2 为本实施例的实现语音信令跟踪的装置的一实例, 若远端用户远程连接上 MG1 , 例如, 指令 MG1对 H248协议信令进行跟踪, 具体跟踪的内容范围为 发送给媒体网关控制器 (Media Gateway Control, MGC ) 的信令, 则 MG1 根据用户的跟踪指令记录相关信令内容的具体流程如下:
1、 MG1检测到用户 Userl的摘机, 将此摘机事件通过通知(Notify )命 令上报给 MGC, 并记录该摘机事件;
2、 MGC向 MG1返回应答(Reply ) ;
3、MGC向 MG1发送修改( Modify )消息,向 MG1发送号码表( Digitmap ); 请求 MG1放拨号音(cg/dt ) ; 并检测收号完成(dd/ce ) 、 挂机( al/on ) 、 以及拍叉簧(al/fl ) 事件; 4、 MG1向 MGC返回应答(Reply ) , 并记录该应答事件;
5、 MG1上的用户 Userl拨号, MG1根据 MGC所下发的号码表进行收 号, 并将所拨号码及匹配结果用通知(Notify )消息上报 MGC, 并记录该拨 号事件;
6、 MGC向 MG1返回 Reply; 7、 MGC向 MG1发送添加 ( Add ) 消息, 在 MG1中创建一个新上下文
