Description

IP传真机的训练方法与装置 技术领域 本发明涉及一种传真机训练的方法与装置， 尤其涉及一种 IP传真机的 训练方法与装置。 背景技术 随着互联网的发展， 在 IP网络中进行实时传真中继的 T.38协议得到了 越来越多的应用。 通常， 一端的 T.38网关将来自与其连接的传真机的调制信 号进行解调， 并将解调的数据封装成符合 T.38协议规定的报文， 通过 IP网 络发给对端的 T.38 网关。 对端 T.38 网关从接收的报文中解析出数据， 将该 数据调制并发送给与该对端 T.38网关连接的传真机。 以下筒单介绍 ip传真的过程： 首先是呼叫建立阶段， 通过手动或自动 的方式完成呼叫， 与 IP电话的呼叫过程一致。 呼叫建立完成后， 可以进行语 音通话。主叫端可以手动按传真机的启动按键，发送传真单音信号给被叫端 , 被叫端会听到 "嘀" 的一声。 其次是传真机能力协商和握手阶段， 该阶段已 进入真正的传真阶段， 主要完成传真机能力标识、 传真训练以及同步等。 由 被叫端传真机发送数字标识信号来进行能力识别。 报文同步及传送阶段， 完 成报文同步 , 误码检测纠错以及线路监控。 同时根据 T.4的规程传输文件 , 按照 T.4定义的调制方式、 传输时间、 传输方式等规定进行传输。 报文证实 阶段， 主要完成报文证实、 多页文件续发以及传真结束信号。 传真呼叫的释 放阶段， 根据传真结束信号或因为超时等网络因素释放呼叫。 目前， 绝大多数具有 T.38 中继功能的媒体网关对传真机间协商阶段的 传真训练有两种方式， 分别是本地训练方式和远端训练方式。 本地训练方式 下， 发方传真机网关不会向收方传真机网关转发训练数据， 而只是发送一个 训练指示的 4艮文；收方传真机网关接收该训练指示后，采用哄骗的方式， 按训练指示的调制方式， 生成训练数据并发送给收方传真机。 远端训练方式 下 , 发方传真机网关除发送训练指示 4艮文外 , 还要发送从发方传真机解调出 来的训练数据 (约 1.5秒的全 0数据）， 收方传真机网关的工作就是将接收到 的训练数据发送给收方传真机。 这样， 在一次传真中， 发方传真机网关和收方传真机网关对于训练方式 的配置就有四种， 分另' J是： 远端-远端、本地-本地、远端-本地以及本地-远端。 前两种组合下双方网关可以顺利进行训练过程， 而后两种组合下就会出现配 置兼容性的问题。 其中， 远端-本地的配置下， 收方传真机网关会接收到并不 期待的 T.38训练数据报文， 可能会造成异常； 而本地-远端的配置下， 收方 传真机网关会期待 T.38训练数据报文 , 但又收不到该报文 , 必定会导致训练 失败。 发明内容 有鉴于此， 本发明的主要目的在于提供一种 IP传真机的训练方法与装 置，能兼容各种训练方式的配置，保证了 IP传真机之间传真文件的顺利传送。 为达到上述目的， 本发明提供了一种 IP传真机的训练方法， 该方法包 括： 收方传真机网关接收到训练指示报文时，判断所述收方传真机当前训练 模式， 若为本地训练模式， 则进行本地训练； 若为远端训练方式， 则在接收 到训练信号报文时进行远端训练， 未接收到训练信号报文时查找前次的训练 信号 4艮文， 若查找到则进行远端训练， 未查找到则进行本地训练。 优选地， 未查找到则进行本地训练， 具体为： 切换所述收方传真机为本 地训练方式， 并在接收到下次训练指示报文时根据所述训练指示报文生成训 练信号， 发送至所述收方传真机， 所述收方传真 艮据所述训练信号进行本 地训练。 优选地， 所述收方传真机为本地训练方式时， 所述收方传真机网关丢弃 所接收到的训练信号报文。 优选地， 所述发方传真机为本地训练方式时， 所述发方传真机通过所述 发方传真机网关仅向所述收方传真机网关发送训练指示报文， 不发送训练信 号 4艮文。 优选地，所述收方传真机网关与发方传真机网关之间基于 IP协议通信。 本发明还提供了一种 IP传真机的训练装置， 该装置包括： 训练模式判断单元， 用于在收方传真机网关接收到训练指示报文时， 判 断所述收方传真机当前训练模式， 若为本地训练模式， 则触发本地训练单元, 若为远端训练方式， 则触发训练信号 文判断单元； 本地训练单元 , 用于进行本地训练； 训练信号 4艮文判断单元，用于判断所述收方传真机网关是否接收到训练 信号报文， 若接收到则触发远端训练单元， 否则触发查找单元； 远端训练单元， 用于进行远端训练； 以及 查找单元， 用于查找前次的训练信号报文， 若查找到则触发远端训练单 元， 否则触发本地训练单元。 优选地， 所述本地训练单元进行本地训练， 具体为： 根据所述训练指示 报文生成训练信号， 发送至所述收方传真机， 所述收方传真机根据所述训练 信号进行本地训练。 优选地， 所述收方传真机为本地训练方式时， 所述收方传真机网关丢弃 所接收到的训练信号报文。 优选地， 所述发方传真机为本地训练方式时， 所述发方传真机通过所述 发方传真机网关仅向所述收方传真机网关发送训练指示报文， 不发送训练信 号报文。 优选地，所述收方传真机网关与发方传真机网关之间基于 IP协议通信。 本发明通过对收方传真机网关进行流程配置，使其在收到训练指示报文 时， 根据收方传真机的当前训练模式确定是生成训练信号还是等待远端的训 练信号， 以及在远端的训练信号超时后， 收方传真机将远端训练方式 4爹改为 本地训练方式， 以在收方传真机网关接收到远端的下次训练指示 4艮文时， 生 成训练信号并致使收方传真机进行本地训练， 以促成发方传真机与收方传真 机之间的传真传送。 本发明能兼容各种训练方式的配置， 保证了 IP传真机之 间传真文件的顺利传送。 附图说明 此处所说明的附图用来提供对本发明的进一步理解 ,构成本申请的一部 分， 本发明的示意性实施例及其说明用于解释本发明， 并不构成对本发明的 不当限定。 在附图中: 图 1为才艮据本发明实施例的收方传真机为本地训练方式下的 IP传真机 的训练方法的流程图； 图 2为才艮据本发明实施例的收方传真机为远端训练方式下的 IP传真机 的训练方法的 程图； 图 3为才艮据本发明实施例的 IP传真机的训练装置的组成结构示意图。 具体实施方式 功能相克述 本发明的基本思想是： 在收方传真机网关进行相应的流程配置 , 使其在 收到训练指示 4艮文时， 才艮据收方传真机的当前训练模式确定是生成训练信号 还是等待远端的训练信号， 以及在远端的训练信号超时后， 收方传真机将远 端训练方式修改为本地训练方式， 以在收方传真机网关接收到远端的下次训 练指示报文时， 生成训练信号并致使收方传真机进行本地训练， 以促成发方 传真机与收方传真机之间的传真传送。 本发明能兼容各种训练方式的配置， 保证了 IP传真机之间传真文件的顺利传送。 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。 由于本发明技术方案是对呼叫建立完成后的传真机能力协商和握手阶 段的改进， 因此对整个 IP传真过程不再赘述， 仅对改进部分进行详述。 方法实施例 图 1为才艮据本发明实施例的收方传真机为本地训练方式下的 IP传真机 的训练方法的流程图， 如图 1所示， 收方传真机为本地训练方式下的 IP传真 机的训练方法包括以下步骤：
指示 4艮文。 在实际应用中， 上述过程可以具体为： 发送方网关被设置为本地训练模 文,但不发送后续的 T.38全 0训练数据。 发方传真机通过^冲编码调制 （ Pulse Code Modulation , 筒称为 PCM ) 总线向发方传真机网关发送训练指示的调制信号， 经过解调后， 将解调后的 训练指示信息进行 IP封装为训练指示 4艮文， 发送给收方传真机网关。 发方传真机为远端训练方式时，发方传真机在向发方传真机网关发送训 练指示的调制信号后 , 还通过 PCM总线向发方传真机网关发送训练数据序 列， 经过解调、 进行 IP封装为训练信号报文发送给收方传真机网关。 如果发 方传真机为本地训练方式， 收方传真机网关接收到训练数据序列时， 直接将 其丢弃。 步骤 102: 收方传真机网关接收到训练指示报文后， 判断与所述收方传 真机网关连接的收方传真机的训练模式为本地训练模式， 将所述训练指示报 文解包并重新调制为训练指示信号， 并发送给收方传真机， 同时开始向收方 传真机调制生成的训练数据序列， 其中， 上述训练序列具体为本地生成的训 练数据序列。 这里， 训练数据序列才艮据训练指示信息确定， 训练指示信息主 要用于指示训练序列的持续时长， 所述的训练数据序列仍为全 "0" 的数据 序列。 在步骤 102中， 接收方网关被设置为本地训练模式。 如果收方传真机网关接收到了训练信号报文序列，在收方传真机的训练 模式为本地训练模式的情况下， 丢弃训练信号报文。 步骤 103: 收方传真机进行本地训练后， 通过收方传真机网关向发方传 真机网关发送训练成功或失败信息， 发方传真机网关将所述训练成功或失败 信息发送给发方传真机， 训练结束。 在该步骤中， 发送方网关被设置为本地 训练模式。 收方传真机的本地训练完成后， 向收方传真机网关发送训练成功确认 ( CFR ) /训练失败（ FTT )信号 , 收方传真机网关将收方传真机的 CFR/FTT 信号解调并进行 IP封装为 CFR/FTT报文， 并发给发方传真机网关， 发方传 真机网关再将其调制为 CFR/FTT信号至发方传真机。 至此，一次训练过程结 束。 图 2为才艮据本发明实施例的收方传真机为远端训练方式下的 IP传真机 的训练方法的流程图， 如图 2所示， 收方传真机为远端训练方式下的 IP传真 机的训练方法包括以下步骤： 指示报文。 发方传真机通过 PCM 总线向发方传真机网关发送训练指示的调制信 号， 经过解调后， 将解调后的训练指示信息进行 IP封装为训练指示报文， 发 送给 4欠方传真机网关。 发方传真机为远端训练方式时，发方传真机在向发方传真机网关发送训 练指示的调制信号后 , 还通过 PCM总线向发方传真机网关发送训练数据序 列， 经过解调、 进行 IP封装为训练信号报文发送给收方传真机网关。 如果发 方传真机为本地训练方式， 收方传真机网关接收到训练数据序列时， 直接将 其丢弃。 步骤 202: 收方传真机网关接收到训练指示报文后， 判断与所述收方传 真机网关连接的收方传真机的训练模式为远端训练模式， 则等待发方传真机 网关侧的训练信号 4艮文， 如果接收到训练信号 4艮文， 则解包所述训练信号， 经过调制后发送至收方传真机， 收方传真机根据所述训练信号进行训练； 若 等待发方传真机网关侧的训练信号 4艮文超时， 收方传真机发出训练失败信号 ( FTT ), 收方传真机网关^1 FTT解调并 装为 FTT 4艮文的形式送给发方传 真机网关， 继而调制给发方传真机。 同时 , 收方传真机网关检测到 FTT信号 后， 判断在前次训练过程中是否收到发方传真机网关侧的训练信号， 如果没 有， 切换为本地训练方式， 否则， 将前次的训练信号发送至收方传真机， 以 使其进行训练。 在步骤 202中， 接收方网关被设置为远端训练模式， 收方传真机网关接 收到训练指示报文后， 判断与收方传真机网关连接的收方传真机的训练模式 为远端训练模式， 则等待发方传真机网关侧的训练信号报文， 若接收到训练 信号报文， 则直接将训练信号发送至收方传真机， 使其进行远端训练； 若等 待训练信号报文超时， 收方传真机发出 FTT信号， 收方传真机网关将前次训 练信号发送至收方传真机或通知发方传真机进行二次训练， 同时切换训练方 式为本地训练方式。 步骤 203:发方传真机发起二次训练。其发起方式与步骤 201完全相同， 这里不再赘述。 步骤 204: 发方传真机进行二次训练， 通过收方传真机网关向发方传真 机网关发送训练成功或失败信息， 发方传真机网关将所述训练成功或失败信 息发送给发方传真机， 训练结束。 收方传真机网关接收到训练指示报文后，将所述训练指示报文解包并重 新调制为训练指示信号， 并发送给收方传真机， 并开始向收方传真机调制生 成的训练数据序列。 这里， 训练数据序列根据训练指示信息确定， 训练指示 信息主要用于指示训练序列的持续时长， 所述的训练数据序列仍为全 "0" 的数据序列。 收方传真机的本地训练完成后， 向收方传真机网关发送 CFR/FTT信号， 收方传真机网关将收方传真机的 CFR/FTT信号解调并进行 IP封装为 CFR/FTT报文， 并发给发方传真机网关， 发方传真机网关再将其 调制为 CFR/FTT信号至发方传真机。 至此， 二次训练过程结束。 才艮据本发明实施例， 还提供了一种计算机可读介质， 该计算机可读介质 上存储有计算机可执行的指令， 当该指令被计算机或处理器执行时， 使得计 算机或处理器执行如图 1和图 2所示的各步骤的处理， ύ选地， 可以执行上 述实施例中的一个或多个。 装置实施例 图 3为才艮据本发明实施例的 IP传真机的训练装置的组成结构示意图， 如图 3所示， IP传真机的训练装置包括训练模式判断单元 30、 本地训练单元 31、 训练信号4艮文判断单元 32、 远端训练单元 33和查找单元 34, 其中， 训 练模式判断单元 30 用于在收方传真机网关接收到训练指示报文时， 判断所 述收方传真机当前训练模式， 若为本地训练模式， 则触发本地训练单元 31 , 若为远端训练方式， 则触发训练信号 4艮文判断单元 32。 本地训练单元 31用 于进行本地训练， 即根据收方传真机网关接收到的训练指示报文生成训练信 号， 发送至所述收方传真机， 所述收方传真 艮据所述训练信号进行本地训 练。 训练信号 4艮文判断单元 32 用于判断所述收方传真机网关是否接收到训 练信号 4艮文， 若接收到则触发远端训练单元 33 , 否则触发查找单元 34。 在 收方传真机为远端训练模式时， 则其必须根据所接收的训练信号报文进行远 端训练， 则需要判断是否收到训练信号 4艮文。 远端训练单元 33 用于进行远 端训练， 即在收方传真机网关接收到训练信号报文时， 进行解析， 将所解析 出的训练信号发送至收方传真机， 收方传真 艮据所接收到的训练信号进行 训练。 查找单元 34 用于查找前次的训练信号 4艮文， 若查找到则触发远端训 练单元 33 , 否则触发本地训练单元 31。 查找单元 34在确定收方传真机网关 未接收到训练信号 4艮文时， 查找该收方传真机网关中是否存在前次接收到训 练信号 4艮文 , 若有则解析所述前次接收到训练信号 ~¾文 , 并发送至收方传真 机使其进行远端训练 , 否则，将收方传真机的训练模式修改为本地训练模式 , 根据收方传真机网关接收到的下一训练指示报文生成训练信号， 发送至所述 收方传真机 , 所述收方传真 艮据所述训练信号进行本地训练。 该装置中， 所述收方传真机为本地训练方式时， 所述收方传真机网关丢 弃所接收到的训练信号报文。 所述发方传真机为本地训练方式时， 所述发方 文， 不发送训练信号报文。 所述收方传真机网关与发方传真机网关之间基于
