详述
下文中将参考附图并结合实施例来详细说明本发明的实施方式。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
实施例1
本申请实施例1所提供的方法实施例可以在网元节点、服务器移动终端、计算机终端或者类似的运算装置中执行。以运行在服务器上为例，图2是本发明实施例的一种拨测方法的网元节点的硬件结构框图。如图2所示，服务器20可以包括一个或多个(图中仅示出一个)处理器22(处理器22可以包括但不限于微处理器MCU或可编程逻辑器件FPGA等的处理装置)、用于存储数据的存储器24、以及用于通信功能的传输装置26。本领域普通技术人员可以理解，图2所示的结构仅为示意，其并不对上述电子装置的结构造成限定。例如，服务器20还可包括比图2中所示更多或者更少的组件，或者具有与图2所示不同的配置。
存储器24可设置为存储应用软件的软件程序以及模块，如本发明实施例中的拨测方法对应的程序指令/模块，处理器22通过运行存储在存储器24内的软件程序以及模块，从而执行各种功能应用以及数据处理，即实现上述的方法。存储器24可包括高速随机存储器，还可包括非易失性存储器，如一个或者多个磁性存储装置、闪存、或者其他非易失性固态存储器。在一些实例中，存储器24可进一步包括相对于处理器22远程设置的存储器，这些远程存储器可以通过网络连接至服务器20。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
传输装置26设置为经由一个网络接收或者发送数据。上述的网络实例可包括服务器20的通信供应商提供的无线网络。在一个实例中，传输装置26包括一个网络适配器(Network Interface Controller，NIC)，其可通过基站与其他网络设备相连从而可与互联网进行通讯。在一个实例中，传输装置26可以为射频(Radio Frequency，RF)模块，其设置为通过无线方式与互联网进行通讯。
在本实施例中提供了一种运行于上述网元节点的拨测方法，图3是根据本发明实施例的拨测方法的流程图一，如图3所示，该流程包括如下步 骤：
步骤S302，通过第二虚拟终端向第一虚拟号码对应的第一虚拟终端发送第一拨测消息，其中，第一拨测消息中携带有第一测试数据，以使第一虚拟终端根据第一测试数据得到第一虚拟终端模拟被叫的第一拨测结果；
步骤S304，检测第一虚拟终端响应第一拨测消息发送的第二拨测消息，其中，第二拨测消息中携带有第二测试数据；
步骤S306，根据第二测试数据得到第二虚拟终端模拟主叫的第二拨测结果。
通过上述步骤，通过两个虚拟终端进行交互，互发测试数据，并根据测试数据得到模拟主被叫拨测的测试结果，提高了拨测效率。
在一实施方式中，在步骤S306中，根据第二测试数据得到第二虚拟终端模拟主叫的第二拨测结果可以有多种方式，例如，在未检测到第二测试数据的情况下，判断出第二虚拟终端模拟主叫的第二拨测结果为模拟拨测失败。又例如，在检测到第二测试数据的情况下，判断第二测试数据与预设测试数据是否一致；在第二测试数据与预设测试数据不一致的情况下，判断出第二虚拟终端模拟主叫的第二拨测结果为模拟拨测失败；在第二测试数据与预设测试数据一致的情况下，判断出第二虚拟终端模拟主叫的第二拨测结果为模拟拨测成功。再例如，还可以判断预设时间段内是否接收到第一虚拟终端发送过来的数据(不论接收到的是什么类型的数据)，如果接收到，判断出第二虚拟终端模拟主叫的第二拨测结果为模拟拨测成功，如果未接收到，判断出第二虚拟终端模拟主叫的第二拨测结果为模拟拨测失败。
下面举例对上述实施例进行说明。
在与第二虚拟终端对应的网元中预先配置期望从其它虚拟终端接收的测试数据(即，预设测试数据)，以及接收测试数据的预设时间，测试数据可以是语音业务数据，还可以是数据业务数据或者其他类型的业务数据。预设时间可以是虚拟终端作为模拟主叫时从向被叫方虚拟终端发送完测试数据的时刻开始的一段时间，还可以是虚拟终端作为模拟被叫时从做出模 拟摘机应答的时刻开始的一段时间。
在预设时间内，检测是否有从第一虚拟终端发送来的第二测试数据。如果检测到第二测试数据，判断检测到的第二测试数据与预设测试数据是否一致。如果是，判断出第二虚拟终端模拟主叫的第二拨测结果为模拟拨测成功。在未检测到第二测试数据，以及检测到的第二测试数据与预设测试数据不一致时，判断出第二虚拟终端模拟主叫的第二拨测结果为模拟拨测失败。
通过本发明实施例，通过不同的检测结果第二虚拟终端模拟主叫的拨测结果，可以更加精确地确定模拟主叫的拨测结果，提高拨测测试的准确性。
在一实施方式中，在步骤S302之前，可以采用多种方式建立第一、第二虚拟终端之间的呼叫连接。例如，可以通过第二虚拟终端的第一端口接收用于指示模拟主叫的第一拨测命令，其中，第一拨测命令中携带有第一虚拟号码；向第一虚拟号码对应的第一虚拟终端发起呼叫；接收第一虚拟终端返回的用于模拟摘机应答的第一应答信号，建立第二虚拟终端与第一虚拟终端之间的呼叫连接。也即，通过第一端口接收用于模拟主叫的拨测命令，该拨测命令中携带有第一虚拟终端对应的第一虚拟号码，此时第一端口虚拟出第二虚拟终端。其他可以建立第一虚拟终端与第二虚拟终端的呼叫连接的方式，均可用来进行本实施例的呼叫连接。
通过本发明实施例，根据拨测命令，在网元的接口虚拟出终端进行拨测测试，可以利用网元的已有结构，无需在网元中添加新的硬件或者复杂的软件模块化即可实现拨测，降低了拨测的成本，降低了拨测测试的复杂度。
在一实施方式中，在步骤S302之前，还可以在第二虚拟终端所在的网元中进行模拟被叫的拨测测试。例如，可以通过第二虚拟终端的第二端口接收模拟被叫的第二拨测命令；在第二端口接收第一虚拟终端发起呼叫的情况下，发送用于模拟摘机应答的第二应答信号；检测第一虚拟终端发送的第三拨测消息，其中，第三拨测消息中携带有第三测试数据；根据第三测试数据得到第二虚拟终端模拟被叫的第三拨测结果，并向第一虚拟终端 发送第四拨测消息，其中，第四拨测消息中携带有第四测试数据，以使第一虚拟终端根据第四测试数据得到第一虚拟终端模拟主叫的第四拨测结果。
通过本发明实施例，第一虚拟终端和第二虚拟终端可以形成模拟主被叫对(同一虚拟终端可以分别与多个其他虚拟终端形成模拟主被叫对)，分别对模拟主被叫对中的虚拟终端进行模拟主叫和模拟被叫的拨测测试，从而实现全面的模拟拨测。
在一实施方式中，在得到拨测结果以后，可以将得到的拨测结果上报给拨测服器。例如，在根据第三测试数据得到第二虚拟终端模拟被叫的第三拨测结果之后，还包括：将得到的模拟被叫的第三拨测结果，上报给拨测服务器。又例如，在根据第二测试数据得到第二虚拟终端模拟主叫的第二拨测结果之后，将得到的模拟主叫的第二拨测结果，上报给拨测服务器。
在本实施例中还提供了一种运行于拨测服务器的拨测方法，图4是根据本发明实施例的拨测方法的流程图二，如图4所示，该流程包括如下步骤：
步骤S402，确定拨测服务器所控制的网络中与第一拨测任务对应的拨测范围，其中，拨测范围包括：多对第一网元和第二网元；
步骤S404，向拨测范围中的第一网元分别发送用于指示进行模拟主叫的第一拨测命令，向拨测范围中的第二网元分别发送用于指示进行模拟被叫的第二拨测命令，以使与第一网元对应的第一虚拟终端及与第二网元对应的第二虚拟终端建立呼叫连接，进行拨测测试；
步骤S406，获取拨测范围中的第一网元上报的模拟主叫的第一拨测结果，以及拨测范围中的第二网元上报的模拟被叫的第二拨测结果；
步骤S408，根据获取的第一拨测结果以及第二拨测结果，定位网络中的故障网元。
通过上述步骤，通过确定拨测服务器控制的网络中与拨测任务对应的拨测范围，并分别向拨测范围内的第一网元和第二网元下发模拟主被叫拨 测命令，并根据第一、第二网元上报的拨测结果，进行故障网元的定位，提高了拨测效率。同时，还可以通过软件的方式进行拨测测试，降低了网络的拨测成本。
在一实施方式中，在步骤S402中，可以通过多种方式确定拨测任务对应的拨测范围。例如，可以以该拨测服务器控制的网络中的所有网元节点作为与拨测任务对应的拨测范围，又例如，可以在该拨测服务器控制的网络中的所有网元节点随机选取若干网元节点作为与拨测任务对应的拨测范围。又例如，还可以根据不同的网络结构，采用不同的规则选择网元节点作为与拨测任务对应的拨测范围：在网络中包括环网的情况下，确定与第一拨测任务对应的拨测范围包括：环网中的至少两个网元；在网络中包括链形网的情况下，确定与第一拨测任务对应的拨测范围包括：链形网的末端网元，以及链形网的除了末端网元以外的至少一个网元。
通过本发明实施例，采用不同的规则选择网元节点作为与拨测任务对应的拨测范围，可以适用于不同的网络拓扑结果，减少了拨测次数，提高了拨测效率。
在一实施方式中，在步骤S402中，还可以采用如下方式确定与拨测任务对应的拨测范围：根据在第一拨测任务之前执行的第二拨测任务的拨测结果，结合网络的网络拓扑结构，确定与第一拨测任务对应的拨测范围，其中，与第一拨测任务对应的第一网络拓扑范围小于与第二拨测任务所对应的第二网络拓扑范围。也即，可以先对较大的网络范围进行拨测测试，根据拨测结果，确定有进一步的拨测需求时(例如，网络中由故障网元节点)，根据前次的拨测结果，缩小拨测范围，在较小的网络范围进行拨测测试。
通过本发明实施例，通过执行两次拨测任务进行故障网元节点的定位，可以减少故障网元定位所需的模拟主被叫的次数，提高故障网元定位的效率。
在一实施方式中，可以采用多种方式定位网络中的故障网元，例如，可以根据第一拨测结果以及第二拨测结果中包含的拨测失败的拨测信息，确定故障网元所在的链路范围；根据确定的链路范围，定位故障网元。
基于上述实施例及实施方式，为说明方案的整个流程交互，在本实施例中，提供了一种拨测系统，以及可以应用该系统的拨测方法，下面分别对本实施例中所提供的系统及方法进行说明。
本实施例中所提供的拨测系统包括：一个或多个自动拨测服务器(作用同前述拨测服务器)。该自动拨测服务器的硬件实体可以是一台个人计算机(Personal Computer，简称为PC)或服务器。根据辖区内需要拨测的网元个数不同，对计算机的性能要求有所变化。但总得来说，并不需要很高级的服务器。因为系统支持分布部署，可以采用多级服务器组网来满足性能要求。如图5所示，该自动拨测服务器在软件方面包括以下几个模块：系统总控模块52、配置管理模块54、呼叫路由选择模块56、呼叫及结果收集模块58、结果分析模块510、结果展示模块512以及数据库模块514。下面分别对上述七个模块的进行描述。
配置管理模块54，可以设置为：
(1)提供用于输入辖区内的网络拓扑、接入网元信息，以及拨测用户信息的界面；
(2)提供对拨测计划进行配置的界面。
系统总控模块52，可以设置为：
(1)根据配置的拨测计划，调度启动拨测任务；
(2)在拨测过程中，根据结果分析模块510的输出结果，确定是进行进一步的拨测，还是拨测结束；
(3)接收外部的请求，对于辖区内的指定节点进行拨测，并将拨测结果返回给请求方。
呼叫路由选择模块56，可以设置为：
(1)接收系统总控模块52的拨测任务，结合网络拓扑自动分析产生拨测的拨测清单，包括主被叫网元以及拨测的号码集合，该拨测清单是最小的测试集合，并将拨测清单发送给呼叫及结果收集模块58；
(2)在进一步拨测时，根据结果分析模块510中的过程数据，结合网络拓扑自动分析产生拨测的主被叫网元以及拨测的号码清单，该清单是足以 定位故障点的测试集合，输出给呼叫及结果收集模块58。
呼叫及结果收集模块58，可以设置为：
(1)在系统总控模块52的调度下，根据呼叫路由选择模块56提供的测试集合，远程登录到主叫网元进行模拟呼叫的测试(远程登录后通过向主叫网元下发拨测命令)，并收集呼叫的结果，并对呼叫结果进行简单分析，以标准形式提供成功或失败的结果；
(2)针对通信网络中的网元存在网元厂家、网元类型多样的情况，根据不同网元的拨测需求，进行相应的处理：对网元下发的拨测命令进行对应调整，从而适用不同的网元，以使模拟呼叫正常进行；
(3)通过算法管理测试集合，对呼叫进行适当的并行处理(即，多个网元同时进行模拟呼叫)，以减少拨测时间。
(4)拨测完成之后，得到呼叫的汇总结果，输出给结果分析模块510。
结果分析模块510，可以设置为：
(1)对呼叫的汇总结果进行分析，判断通信网络是否存在拨测问题(拨测不成功，例如，网元作为主叫或者被叫时拨测失败)；
(2)在判断存在问题的情况下(即，存在故障网元)，分析汇总结果，得到一个缩小的拓扑图(也就是缩小网络拓扑图，把故障节点定位在一个更小的范围内)，提供给系统总控模块52，进行进一步的拨测；
(3)在判断拨测完成的情况下，输出拨测的结果给结果展示模块512。
结果展示模块512，可以设置为：
(1)根据接收到的拨测结果进行展示；
(2)在展示中，对于故障点进行重点呈现；
(3)对历史的拨测结果进行回溯。
数据库模块514，可以设置为：
存储网络拓扑、网元的拨测结果等。
在该自动拨测服务器中，除配置管理模块54、数据库模块514外，其它几个模块的协作如图6所示。系统总控模块52负责任务的下发及决策； 呼叫路由选择模块56根据任务要求分解得到呼叫清单；呼叫及结果收集模块58根据呼叫清单进行呼叫；结果分析模块510分析呼叫结果，在需要进一步呼叫时，提供必要的信息给总控模块进行详细拨测；结果展示模块512展示呼叫结果以及发现的问题。
呼叫路由选择模块56结合网络拓扑自动分析产生拨测的主被叫网元以及拨测的号码集合，在第一次是个呼叫清单的简集，第二次是缩小拓扑后的呼叫清单的全集。
下面对拨测服务器所控制的网络的拓扑结构进行说明。
图7是根据本发明实施例的通信网络的组网结构图一，如图7所示，该通信网络的组网结构为基层通信网络，该网络是一个环形加链形的网络；通信网络会存在很多这样的基层通信网络，多个网络在一起就形成如图8所示的组网结构。
由图7、图8可以看出，网络上的网元数量相当多，如果进行两两的拨测，那么呼叫量非常大，占用时间长，效率不高。所以可以对测试集做一定的简化，从而提高拨测效率。
可以采用下面的原则进行简化：
(1)环网，可以随机的对环上的结点采集若干个进行测试。
(2)链形网，可以随机的对链上非端点的结点采集若干个进行测试，以及对链的末端结点进行测试。
因为测试的次数比较多，随机的测试也能保证在一段时间内网络上的所在结点都会被测试到。
以图7为例，假设第一次测试的网元集合是网元A1、A2、A4、A7、B2、B3。在测试时，发现网元A4与网元A1间拨测有问题。
为了分析故障点，缩小拓扑到该故障点所在的环网，呼叫路由选择模块分析该环网，生成对环网上的所有点进行拨测的呼叫清单，假设清单是A1分别与A2-A8各点进行拨测。
通过呼叫及结果收集模块的拨测，根据拨测的结果来确认故障点。假设发现只有A1与A3、A1与A4不通，这样可以得到如图9所示的结果， 即A3与A2间断开，A4与A5间断开。
在呈现方面，在结果展示模块中采用无级缩放的方式，呈现出类似于图8、图9综合起来的效果。
本实施例中所提供自动拨测服务器具有简易的堆叠的能力。它可以接受外部的请求，对于辖区内的指定节点进行拨测，并返回拨测结果给请求方。分层部署的自动拨测服务器组网如图10所示。对于图10中的上级拨测服务器，它的被测试网元分属于各下属辖区，它是所有下属辖区网元的一个子集，由这个子集组成拨测号码集合。当发现出现拨测异常时，它请求相关的下属拨测服务器进行进一步分析，当下属拨测服务器并返回结果时，在上级拨测服务器的结果呈现模块进行呈现。
上级服务器与下级服务器协作如图11所示。通过协作，上级服务器可以方便的进行全网拨测而不必管理所有的网元。在网络结点更多的情况下，可以出现多级的服务器组网，这样会存在有的服务器它既是下级网络的上级服务器，也是上级网络的下级服务器的情况。此时依旧采用逐级下发的方式进行故障点的进一步拨测，最后得到的拨测结果逐级上传，从而达到堆叠组网，覆盖全网的效果。
下面对本发明实施例中的拨测方法进行阐述。
大多数的接入网关均支持模拟主叫功能与模拟被叫功能。模拟主叫功能与模拟被叫功能如下：
1)接入网关的模拟主叫功能
接入网关具备的模拟主叫功能可以如图12所示。当接收到模拟主叫的命令后，网元(如，接入网关)在系统中模拟了一个虚拟用户，通过虚拟用户发起一个呼叫给测试配合人，测试配合人听到振铃之后，摘机，听到虚拟用户发出的特殊音(例如，可以是双音多频音，或者其它类型的声音)，确认语音正常之后，配合测试人挂机，网元出具模拟主叫测试的结果报告。
从上述过程可以看出，语音的正常检测只是确认了从虚拟用户发送到测试配合人的单向语音正常。
2)接入网关的模拟被叫功能
接入网关具备的模拟被叫功能可以如图13所示。当接收到模拟被叫的命令后，网元(如，接入网关)在系统中模拟了一个虚拟用户，测试配合人发起一个呼叫给虚拟用户，虚拟用户检测到振铃的信令之后，模拟摘机，测试配合人听到虚拟用户发出的特殊音(例如，可以是双音多频音，或者其它类型的声音)，确认语音正常之后，配合测试人挂机，网元出具模拟被叫测试的结果报告。
从上述过程可以看出，语音的正常检测只是确认了从虚拟用户发送到测试配合人的单向语音正常。
本发明实施例中所提供的拨测方法，对接入网关的模拟主叫、模拟被叫功能进行改造，该拨测方法如图14所示，模拟拨测需要两个虚拟用户，假设主叫方的是虚拟用户A，被叫方的是虚拟用户B。
当网元A接收到虚拟用户A的模拟拨测的要求时，虚拟了一个主叫方的用户A。当网元B接收到虚拟用户B的模拟拨测试的要求时，虚拟了一个被叫方的用户B。虚拟用户A自动发起一个呼叫给虚拟用户B，B模拟摘机应答，A发送特殊音，B检测；然后B发送特殊音，A检测；然后分别挂机，释放资源。呼叫释放之后，网元A出具模拟拨测的结果报告，报告中描述虚拟用户A是否听到虚拟用户B的特殊音；网元B出具模拟拨测的结果报告，报告中描述虚拟用户B是否听到虚拟用户A的特殊音。
从这个过程可以看出，模拟拨测的语音检测是双向的，确保了呼叫可达，且通话的双向语音功能正常。
上述拨测方法，是对语音进行双向的检测。如果将它扩展到数据业务，对数据业务中的传真、Modem数据的双向通信进行检测，那么就可以将本实施例中所述的拨测方法应用于数据业务的自动拨测。
关于接入网关的模拟拨测方法，下面采用一个实施范例来进行描述，主要描述呼叫及结果收集模块中的实施过程。
下面以某一型号的接入网关的模拟呼叫操作方法进行说明。
1、模拟被叫功能
calleesimulate slot 2 index 0 action 1 timeout 60
说明：将槽位2端口0模拟为被叫，它会等待有人呼入。
get-callsimulateinfo slot 2 index 0
说明：获取模拟被叫测试的结果。
2、模拟主叫功能
callersimulate slot 1 index 0 action 1 dialno calledid timeout 60
说明：在槽位1端口0拨打calledid号码。
get-callsimulateinfo slot 1 index 0
说明：获取模拟主叫测试的结果。
3、对模拟主叫功能与模块被叫功能进行改进之后，可以得到模拟拨测功能。采用拨测功能进行拨测的过程如下：
假设槽位2端口0的号码是19860000，设置模拟主叫的calledid的号码是19860000。模拟主叫用户记作用户A，模拟被叫用户记作用户B。
依次执行前述模拟主叫和模拟被叫的配置操作，执行之后，用户A会自动拨打用户B；用户B自动摘机应答之后，A发送特殊音，B检测；然后B发送特殊音，A检测；然后分别挂机，释放资源。
在用户A听用户B特殊音正常的情况下，主叫方得到模拟主叫的拨测结果为“Result:SIM_SUCCESS”，反之，得到模拟主叫的拨测结果为“Result:SIM_FAILED”；在用户B听用户A特殊音正常的情况下，被叫方得到模拟被叫的拨测结果为“Result:SIM_SUCCESS”，反之，得到模拟被叫的拨测结果为“Result:SIM_FAILED”。
一次呼叫及结果收集的主要处理过程如下：
(1)根据拓扑信息中描述的网元类型，生成模拟主叫、模拟被叫的命令。
(2)通过网元的管理通道，连接到主被叫网元上，执行模拟拨测中的模拟主叫、模拟被叫的命令。
(3)过一段时间后，在主被叫网元上获取模拟拨测的结果。
(4)分析得到拨测成功或失败的结果。
通过本发明实施例，提供了一种拨测方法，该方法可以应用于一个分布式的、可堆叠的自动拨测系统，该拨测系统提供了呼叫路由选择、呼叫及结果收集、结果分析以及结果呈现的功能，为通信网络的拨测提供低成本的解决方案。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本申请可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例所述的方法。
