否则, 媒体网关 4不使用指定的 IP接 口进行处理。 或者, 媒体网关 4也可以先判断该呼叫号码是否与预先设置的测 试呼叫号码与 IP接口的对应关系中的某个测试呼叫号码匹配, 如果是, 则进一 步判断是否需要为当前呼叫建立 IP承载, 如果是, 则在为该呼叫建立 IP承载 时, 指定该 IP承载使用与呼叫号码对应的 IP接口发送报文。 在实际应用中, 用户可以通过操作维护系统设置控制实体 2中存储的测试 呼叫号码和媒体网关 4中存储的上述对应关系。 或者, 用户也可以直接在控制 实体 2中设置上述测试呼叫号码, 在媒体网关 4中设置上述对应关系。 通过本发明实施例提供的上述系统, 控制实体 2通过使用测试呼叫号码发 起呼叫, 媒体网关 4在为该呼叫建立 IP 载时, 使用与测试呼叫号码对应的 IP接口, 从而可以直接根据是否能收到呼叫的语音判断对应的 IP接口是否发 生异常, 简化了 IP接口异常定位的流程, 降低了对测试人员的要求, 节约了测 试时间, 提高了 IP接口异常定位的效率。 图 3是 居本发明实施例的控制实体 2的结构示意图, 如图 3所示, 本发 明实施例的控制实体 2可以包括: 存储模块 20, 设置为保存预设的一个或多个 测试呼叫号码; 判断模块 22 , 设置为判断当前发起的呼叫的呼叫号码是否与存 储模块 20中保存的某个测试呼叫号码匹配, 如果是, 则触发发送模块 24向媒 体网关 4发送携带该呼叫号码的命令, 否则, 触发发送模块 24 向媒体网关 4 发送不携带该呼叫号码的命令; 发送模块 24 , 设置为向媒体网关 4发送命令。 通过本发明实施例提供的上述控制实体 2 , 可以在呼叫号码为测试呼叫号 码时, 将呼叫号码携带在命令中发送媒体网关 4 , 从而使得媒体网关 4可以获 知当前的呼叫为测试呼叫, 从而使用与呼叫号码对应的 IP 接口为该呼叫建立 IP承载, 从而可以通过测试呼叫判断对应的 IP接口是否发生异常, 以简化现 有 IP接口异常定位的流程, 降氏 IP接口异常定位的复杂度。 例如, 存储模块 20 中保存的测试呼叫号码可以是用户通过操作维护系统 发送给控制实体 2的, 也可以是用户直接在控制实体 2中设置的。 在实际应用中, 当使用某个测试呼叫号码进行呼叫测试结束后, 为了节约 控制实体 2的存储空间, 控制实体 2可以删除存储模块 20中保存的该测试呼 叫号码, 因此, 控制实体 2还可以包括执行模块, 设置为在测试呼叫结束后, 删除存储模块 20 中与上述呼叫号码匹配的测试呼叫号码, 或者, 执行模块也 可以删除存储模块 20 中保存的用户需要删除的某个测试呼叫号码。 例如, 用 户可以通过操作维护系统向控制实体 2发送需要删除的测试呼叫号码, 操作维 护系统将该测试呼叫号码发送给控制实体 2,执行模块在存储模块 20中查询该 测试呼叫号码, 找到后删除该测试呼叫号码。 图 4是根据本发明实施例的媒体网关 4的结构示意图, 如图 4所示, 媒体 网关 4可以包括: 存储模块 40, 设置为存储预先设置的测试呼叫号码与 IP接 口的对应关系; 接收模块 42 , 设置为接收控制实体在发起呼叫时发送的命令; 判断模块 44, 设置为判断该命令中是否携带有呼叫号码, 以及是否需要为该呼 叫建立 IP承载, 如果均是, 则触发获取模块 46; 获取模块 46, 设置为从存储 模块 40保存的对应关系中获取与上述呼叫号码对应的 IP接口; 建立模块 48 , 设置为为上述呼叫建立 IP承载,指定该 IP承载的报文从获取模块 46获取的 IP 接口发出。 通过本发明实施例提供的媒体网关 4 , 可以在为测试呼叫建立 IP 载时, 指定使用与测试呼叫号码对应的 IP接口发送 4艮文,从而可以通过听耳又测试呼叫 的语音是否正常来判断该 IP接口是否发生异常, 进而降低了 IP接口异常判定 的复杂度, 节约了成本。 例如, 存储模块 40中保存的测试呼叫号码与 IP接口的对应关系可以是用 户通过操作维护系统发送给媒体网关 4的, 也可以是用户直接在媒体网关 4中 设置的。 在实际应用中, 当使用某个测试呼叫号码进行呼叫测试结束后, 为了节约 媒体网关 4的存储空间, 媒体网关 4可以删除存储模块 40中保存的与测试呼 叫号码匹配的记录, 因此, 媒体网关 4还可以包括执行模块, 设置为在测试呼 叫结束后, 删除存储模块 40保存的对应关系中与上述呼叫号码匹配的记录, 或者, 执行模块也可以删除存储模块 40 中保存的用户需要删除的某个对应关 系。 例如, 用户可以通过操作维护系统向控制实体 2发送需要删除的测试呼叫 号码,或者需要删除的测试呼叫号码与 IP接口,操作维护系统将该测试呼叫号 码或者测试呼叫号码与 IP接口发送给媒体网关 4 , 执行模块在存储模块 40保 存的对应关系中查询该测试呼叫号码, 找到后删除与该测试呼叫号码的对应关 系, 或者, 查询该测试呼叫号码与 IP接口, 找到后删除该测试呼叫号码与 IP 接口。 图 5是根据本发明实施例的 IP接口的测试方法的流程图,该方法用于在承 载和控制分离的通信网络中测试 IP接口, 如图 5所示, 该方法包括以下步骤: 步骤 S 502 , 控制实体 2发起呼叫, 确定该呼叫的呼叫号码为预设的测试呼 叫号码, 向媒体网关 4发送携带该呼叫号码的命令; 例如, 控制实体 2可以查找预先保存的测试呼叫号码, 判断当前呼叫的呼 叫号码是否与预先保存的某个测试呼叫号码匹配, 如果是, 则向媒体网关 4发 送携带该呼叫号码的命令, 否则, 向媒体网关 4发送不携带呼叫号码的命令。 步骤 S504 , 媒体网关 4确定需要为该呼叫建立 IP 载, 获取预先设置的 与该呼叫号码对应的 IP接口; 例如,媒体网关 4可以通过查询预先设置的测试呼叫号码与 IP接口的对应 关系,从中获取与该呼叫号码匹配的测试呼叫号码对应的 IP接口,如果对应关 系中不存在与呼叫号码匹配的测试呼叫号码, 则媒体网关 4在后续不使用指定 的 IP接口, 按正常呼叫进行处理。 步骤 S506, 媒体网关 4为当前呼叫建立 IP承载, 指定该 IP载从上述 IP 接口发送 4艮文; 步骤 S508, 根据是否能够听到该呼叫的语音, 判断上述 IP接口是否存在 异常。 如果可以听到该呼叫的语音, 则说明上述 IP接口正常, 否则, 说明该 IP 接口发生异常。 通过本发明实施例提供的上述方法, 釆用呼叫测试对 IP 接口进行异常定 位,可以直接根据呼叫的语音情况判断 IP接口是否存在异常,简化了测试过程, 缩短了测试时间, 并且降低了对操作人员的要求。 图 6是本发明实施例中使用测试呼叫号码进行呼叫的流程图,如图 6所示, 在本发明实施例中, 使用测试呼叫号码进行呼叫主要包括以下步骤: 步骤 601 , 设定测试呼叫号码, 存储在控制实体 2上;

步骤 604, 控制实体 2向 MGW 4下发未携带测试呼叫号码的命令, 之后 进入步骤 608; 步骤 605 , 接收到命令后, MGW 4判断此呼叫是否需要建立 IP承载, 且 该测试呼叫号码是否与保存的测试呼叫号码对应, 若是, 进入步骤 606, 否则 转入步骤 608按正常流程处理; 步骤 606, MGW 4建立 IP 载, 指定该 IP 载从与该测试呼叫号码对应 的指定的 IP接口出报文, 并向操作维护系统上报指定成功消息; 步骤 607, IP承载建立成功后, 对外发送报文时, 将媒体报文, 从指定的 IP接口发出; 测试人员可以听取该呼叫的语音, 如果该呼叫的语音正常, 则上述指定的
IP接口正常, 否则, 上述指定的 IP接口发生异常。 结束呼叫测试后, 转入步 4聚 609; 步骤 608, 按正常流程处理呼叫, 不作指定 IP接口处理; 步骤 609, 删除控制实体 2中存储的测试号码、 删除 MGW 4中存储的测 试号码和 IP接口的对应关系。 通过上述流程, 可以通过使用预设的测试呼叫号码发起呼叫, 测试指定的 IP接口是否发生异常, 从而对 IP接口异常进行定位。 图 7为本发明实施例中在控制实体 2中设置测试呼叫号码的流程图, 如图 7所示, 主要包括以下步 4聚: 步骤 701 , 用户通过操作维护系统的人机界面输入需要存储的测试呼叫号 码信息; 步骤 702, 操作维护系统将用户输入的相关信息发送给控制实体 2保存; 步骤 703 , 控制实体 2判断数据保存成功, 则返回设置成功消息给操作维 护系统的人机界面; 否则返回设置失败消息给操作维护系统的人机界面。 通过上述流程, 可以通过操作维护系统设置控制实体 2中保存的测试呼叫 号码, 使得测试呼叫号码的设置易于实现。 图 8是本发明实施例中设定并在 MGW 4中存储测试呼叫号码和 IP接口的 对应关系的流程图, 如图 8所示, 可以包括以下步 4聚: 步骤 801 , 用户通过操作维护系统的人机界面输入需要存储的测试号码与 IP接口的对应关系信息; 步骤 802, 操作维护系统将用户输入的相关信息, 发送给 MGW4保存; 步骤 803 , MGW 4判断数据保存成功, 则返回设置成功消息给操作维护系 统的人机界面; 否则返回设置失败消息给操作维护系统的人机界面。 通过上述流程, 可以通过操作维护系统设置 MGW 4中保存的测试呼叫号 码与 IP接口的对应关系, 使得测试呼叫号码与 IP接口的对应关系的设置易于 实现, 保证数据的安全性。 图 9是本发明实施例中删除控制实体 2中存储的测试呼叫号码的流程图, 如图 9所示, 主要包括以下步 4聚: 步骤 901 , 用户通过操作维护系统的人机界面输入需要删除的测试呼叫号 码信息; 其中, 该测试呼叫号码可以是刚结束呼叫测试使用的测试呼叫号码, 也可 以是才艮据用户意愿确定的测试呼叫号码。 步骤 902, 操作维护系统将用户输入的相关信息发送给控制实体 2; 步骤 903 , 控制实体 2接收上述相关信息, 删除保存的与用户输入的测试 呼叫号码匹配的测试呼叫号码, 并判断数据是否删除成功, 如果成功则返回删 除成功消息给操作维护系统的人机界面; 否则返回删除失败消息给操作维护系 统的人机界面。 通过上述流程, 可以通过操作维护系统删除控制实体 2上保存的测试呼叫 号码, 易于用户操作, 保证数据的安全性。 图 10是本发明实施例中删除 MGW 4中存储的测试呼叫号码与 IP接口的 对应关系的流程图, 如图 10所示, 主要包括以下步 4聚: 步骤 1001 ,用户通过操作维护系统的人机界面输入需要删除的测试呼叫号 码信息、 IP接口信息; 用户也可以只输入需要删除的测试呼叫号码, 指示删除 MGW 4保存的对 应关系中与该测试呼叫号码匹配的记录(即删除该测试呼叫号码以及与该测试 呼叫号码对应的 IP接口;)。 步骤 1002 , 操作维护系统将用户输入的相关信息发送给 MGW 4; 步骤 1003 , MGW 4接收上述相关信息, 并执行相应的删除操作, 再判断 数据是否删除成功, 如果成功则返回删除成功消息给操作维护系统的人机界 面; 否则返回删除失败消息给操作维护系统的人机界面。 通过上述流程, 可以通过操作维护系统删除 MGW 4上保存的对应关系, 易于用户操作, 保证了数据的安全性。 需要说明的是, 在本发明实施例中, 上述控制实体 2包括但不限于软交换 网络中的 MGC。 从以上的描述中, 可以看出, 釆用本发明实施例提供的技术方案, 简化了 测试过程, 缩短了测试时间, 并且对操作人员不需要艮高的要求。 显然, 本领域的技术人员应该明白, 上述的本发明的各模块或各步骤可以 用通用的计算装置来实现, 它们可以集中在单个的计算装置上, 或者分布在多 个计算装置所组成的网络上, 可选地, 它们可以用计算装置可执行的程序代码 来实现, 从而, 可以将它们存储在存储装置中由计算装置来执行, 并且在某些 情况下, 可以以不同于此处的顺序执行所示出或描述的步骤, 或者将它们分别 制作成各个集成电路模块, 或者将它们中的多个模块或步骤制作成单个集成电 路模块来实现。 这样, 本发明不限制于任何特定的硬件和软件结合。 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, 对于本领 域的技术人员来说, 本发明可以有各种更改和变化。 凡在本发明的 ^"神和原则 之内, 所作的任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之 内。
