实现电话业务所釆用的无线通信模块 120的一种具体形式包括： 空口和 无线通信控制单元。 其中： 空口用于与无线网络 400相连通； 无线通信控制 单元用于通过空口接收和发送终端 200 与无线网络 400 之间交互的语音数 据， 负责执行编码、 调度等相关的无线处理。
优选地， 本实施例中的监控模块 130 包括连通性监控单元和网络设备监 控单元。 其中， 连通性监控单元与宽带通信模块 110的宽带网络接口 111相 连， 用于当监测到宽带网络 300的连通性失效时， 触发切换模块 140; 网络 设备监控单元与宽带网络接口 111相连， 用于当监测到宽带网络 300侧的网 络设备发生故障时， 触发切换模块 140。 需要说明的是， 宽带网络 300的连通性失效和网络设备的故障都可以导 致宽带通信模块 110实现的交互通道失效。 即交互通道失效包括连通性失效 和网络设备的故障两种情况， 例如， 当监测到 IMS 系统的注册服务器出现故 障的情况。 具体应用中， 终端 200与宽带网络 300之间的交互通道失效的形 式还可以有多种， 例如宽带通信模块 110无法正常工作也能导致交互通道失 效。 监控模块 130对宽带网络 300连通性的监测和对网络设备的监测可以通 过心跳机制、 重传次数和响应消息等多种途径实现。
当监控模块 130监测到 VOIP服务不可用时， 就可以触发切换模块 140, 切换模块 140切换到无线网络 400 , 通过无线网络 400来通信， 不仅可以实 现电话业务， 又可以在宽带网络 300连通性故障或网络设备故障的情况下， 通过无线网络 400继续为用户提供电话业务。 上述技术方案可以有效利用无 线网络设备， 无须再维护 PSTN/ ISDN 网络设备， PSTN/ISDN 网络设备可逐渐 予以淘汰， 从而可以降低运营成本。 典型的情况是， 上述技术方案解决了依 赖于 "PSTN/IS匪" 设备保证 VOIP电话业务生命线功能的问题， 釆用本发明 实施例， 当终端和宽带网络之间的交互通道失效时， 可以通过无线的方式实 现电话业务， 从而提供可靠的生命线功能。
实施例二
图 3为本发明实施例二提供的电话业务宽带通信装置的结构示意图。 本 实施例与实施例一的区别在于， 本实施例的多业务宽带通信装置 100包括 IP 端口， 用于连接计算机（PC )作为终端 200, 计算机通过安装客户端软件， 将语音数据转换为 IP数据进行传输来实现电话功能。 典型的 IP端口通常可 以为以太网线（ETH )接口、 WIFI (又称 802. 11协议）接口等， 例如 RJ45接 口。
本实施例中的切换模块 140包括 IP数据处理单元 142。 其中， IP数据处 理单元 142与用于连接计算机作为终端 200的 IP端口相连。 IP数据处理单 元 142用于在计算机和宽带网络 300之间的交互通道中传输经 IP语音分组处 理模块 150处理的 IP数据。 在监控模块 130触发 IP数据处理单元 142时， 该 IP数据处理单元 142切换至在计算机和无线网络 400之间的交互通道中传 输经 IP语音分组处理模块 150处理的 IP数据。 具体的， 监控模块 130在触 发 IP数据处理单元 142动作时， 可以是变更 IP数据处理单元 142中的路由 表内的 IP包的发送端口， 当宽带通信模块 110实现的交互通道失效时， 即可 以将路由表内的 IP包发送端口变更为无线通信模块 120的端口。 IP数据处 理单元 142根据路由表为 IP包设置发送端口， 而后经 IP语音分组处理模块 150的处理后从对应的发送端口发送。
当监控模块 130监测到 VOIP服务不可用时， 就可以触发 IP数据处理单 元 142 , IP数据处理单元 142切换到无线网络 400, 通过无线网络 400来通 信， 既可以优先使用 VOIP实现电话业务， 又可以在宽带网络 300连通性故障 或网络设备故障的情况下， 通过无线网络 400继续为用户提供电话业务。 上 述技术方案可以有效利用无线网络设备， 无须再维护 PSTN/ IS匪网络设备， PSTN/ 1 SDN网络设备可逐渐予以淘汰， 从而可以降低运营成本。
实施例三
图 4为本发明实施例三提供的电话业务宽带通信装置的结构示意图。 本 实施例与实施例一或实施例二的区别在于还包括定位模块 190。定位模块 190 用于基于定位系统识别本地的信息， 当监控模块 130监测到终端 200在当前 使用的交互通道中呼叫紧急服务中心 （Emergency Service Center ) 600时， 该本地的信息可以通过无线通信模块 120或宽带通信模块 110发送给紧急服 务中心 600。 其中， 当前使用的交互通道可以是宽带通信模块 110 实现的， 也可以是无线通信模块 120实现的。
其中， 本地的信息包括本地的位置坐标， 或包括本地的位置坐标和与该 本地的位置坐标对应的地址信息。
定位模块 190可以使用天线部件与全球定位系统（Globa l Pos i t ioning Sys tem; 以下简称： GPS )卫星 500通过空口交互， 获取卫星信号来识别位置 坐标。 定位模块 190可以基于美国的 GPS、 俄罗斯的定位系统（GL0NASS )、 欧洲的伽利略定位系统 （ Ga 1 i leo ) 、 中国的北斗卫星定位系统或辅助 GPS ( As s i s ted GPS; 以下简称： A-GPS )等定位系统来实现。 当本地的地址信息 包括本地的位置坐标时， 该定位模块 190可以包括坐标识别单元 191 , 这时， 坐标识别单元 191基于定位系统识别本地的位置坐标后， 可以通过宽带网络 300连接紧急服务中心 600 ,或可以通过无线网络 400连接紧急服务中心 600 , 具体地釆用哪种方式连接紧急服务中心 600取决于当前所使用的交互通道是 由宽带通信模块 110来实现的还是由无线通信模块 120来实现的。 所谓本地 的， 就是定位模块 190所在位置， 也就是集成有该定位模块 190的多业务宽 带通信装置 1 00所在的位置， 实际上通常就是终端 200所在的位置， 通过这 种方式终端 200能够在呼叫紧急服务中心 600 , 例如呼叫 1 10、 91 1、 120或 999 时， 同时向紧急服务中心 600发送本地的信息， 以在电话业务实现生命 线功能时及时有效的定位终端 200所在位置。
更进一步， 宽带网络 300侧的 IMS/NGN 320或者无线网络 400还可以与 已有的 PSTN/ I SDN700网络通过媒体网关类设备相连，完成相互之间的信令和 媒体流的转换， 以便利用现有的 PSTN/ I SDN700网元设备， 连接架构如图 4所 示。
其中， 本地的信息包括本地的位置坐标和与该本地的位置坐标对应的地 址信息时， 实现地址信息获取的定位模块 190包括： 坐标识别单元 191和地 址获取单元 192。 其中： 坐标识别单元 191用于基于定位系统识别本地的位 置坐标； 地址获取单元 192用于根据本地的位置坐标在地址信息中心 （ AIC ) 800 中查询获取对应的地址信息。 通过这种方式， 终端 200也可以呼叫紧急 服务中心 600。
在上述釆用的定位模块 190中， 坐标识别单元 191基于定位系统所获取 的位置坐标可以存储在寄存器中， 优选的是周期性地通过卫星定位来识别本 地的位置坐标， 并在识别到的位置坐标与寄存器中的已存位置坐标不一致时 对寄存器进行更新， 以保证寄存器中的位置坐标为最新的位置坐标。
其中， 地址信息中心 800可以是预存在多业务宽带通信装置 100本地的 坐标位置与详细的行政地址之间的映射表， 优选的是将地址信息中心 800设 置在网络侧，各个多业务宽带通信装置 1 00可以通过宽带网络 300和 /或无线 网络 400共享地址信息中心 800 , 即定位模块 190的地址获取单元 192可以 通过宽带通信模块 110和 /或无线通信模块 120与地址信息中心 800交互。
在上述技术方案的基础上， 本实施例的装置， 也就是多业务宽带通信装 置 100还可以包括显示模块 180。 显示模块 180与地址获取单元 192相连， 用于将地址信息显示给用户， 即可以将位置坐标所对应的详细行政地址显示 给用户， 以便得到用户的确认或者变更， 显示模块 180可以在接收到用户输 入的地址信息更新命令时， 将地址信息更新命令发送给地址信息中心 800进 行更新， 具体可以是通过宽带通信模块 110或无线通信模块 120进行发送， 将更新地址信息中心 800中该位置坐标对应的地址信息。 上述技术方案使得 用户可以通过显示模块 180来确认地址信息中心 800反馈回的详细地址信息 是否正确。 如果不正确， 可以向地址信息中心 800管理机构进行反馈纠正。
本实施例的技术方案可以实现， 当用户在紧急情况下呼叫紧急服务中心 600时， 可以通过宽带通信模块 1 10或无线通信模块 120 自动将寄存器中保 留的定位系统位置坐标通过特定的程序接口发送给紧急服务中心 600。
本实施例的技术方案优选的是将宽带通信模块 110、 无线通信模块 120、 监控模块 1 30和定位模块 190集成在同一物理装置实体中， 通过同一个 SLIC 单元 141与终端 200相连， 便于实现监测切换控制机制， 且便于实现优先釆 用宽带通信模块 110来实现电话业务的机制。
实施例四
图 5为本发明实施例四提供的电话业务宽带通信装置的结构示意图。 本 实施例可以以上述各实施例为基础， 且还进一步包括电源模块 160 , 且电源 模块 160包括主电源接口 161、 备用电源 162和电源监测单元 163 , 其中： 主 电源接口 161用于插接电源线给需要供电的功能模块供电；电源监控单元 163 与主电源接口 161和备用电源 162相连， 用于当监测到主电源接口 161停止 供电时， 触发备用电源 162给需要供电的功能模块供电。
在本实施例中， 备用电源 162可以为备用电池等。 主电源接口 161可以 与各个需要供电的功能模块相连 (具体连接关系图中未示）， 例如宽带通信模 块 110、 无线通信模块 120、 监控模块 1 30、 切换模块 140和终端 200等， 从 而实现供电。 备用电源 162至少与无线通信模块 120、 定位模块 190和终端 200相连（具体连接关系图中未示出）， 用于在主电源接口 161断电时， 例如 家中和公司停电时， 为无线通信模块 120、 定位模块 190和终端 200提供辅 助供电， 维持其工作， 尤其适用于电话机作为终端 200时的情况。
本实施例的技术方案解决了 VOIP 电话业务可能因为用户住宅或公司停 电时而无法实现的问题， 无线通信模块 120所需的电能较小， 可以用备用电 源 162来维持供电， 从而维持电话业务， 提供可靠的生命线功能。
基于上述实施例所提供的装置， 其具体工作过程可以包括：
首先为该装置的初始化过程， 在正常工作情况下， 宽带通信模块 1 10上 电启动后进行常规的初始化处理， 而后处于运行状态， 实现宽带网络 300与 终端 200之间的交互通道， 当有电话呼叫时， 即实现电话业务； 无线通信模 块 120在上电启动后进行常规的初始化处理， 完成初始化处理后， 与外部无 线网络 400建立连接， 然后无线通信模块 120可以发送就绪消息（ READY )给 监控模块 1 30 , 告知其已经完成初始化处理， 可以进行通信了， 定位模块 190 在上电启动后同样进行常规的初始化处理， 以便开始获取本地的信息。
初始化完成后该装置进入正常工作状态， 即基于宽带通信模块 110实现 宽带网络 300与终端 200之间的交互通道，基于 VOIP实现电话业务， 在此过 程中， 定位模块 190可以定期地釆集卫星信号， 获取本地的信息保存在寄存 器中， 并通过定期地釆集来更新寄存器中的地址信息。 同时， 监控模块 1 30 可以实时地监测宽带网络 300与终端 200之间交互通道的可用性， 若监测到 宽带网络 300与终端 200之间的交互通道失效， 则触发无线工作状态， 即触 发切换模块 140连通终端 200与无线网络 400之间的交换通道，实现终端 200 与无线网络 400之间的交换通道。 所谓宽带网络 300与终端 200之间的交互 通道失效， 可以是由于宽带网络 300连通性故障、 宽带网络 300设备故障等 原因导致的。
在无线工作状态时，无线通信模块 120处于运行状态， 实现无线网络 400 与终端 200之间的交互通道， 随时准备为用户提供电话业务， 尤其是能够保 证为用户提供生命线功能。
当监测到紧急呼叫时， 将定位模块 190获取到的信息通过当前使用的交 互通道发送给紧急服务中心 600, 优选的是由监控模块 130对当前使用的交 互通道进行监测， 当监测到紧急呼叫时， 通过宽带通信模块 110或无线通信 模块 120将地址信息发送给紧急服务中心 600。 即监控模块 130还可以包括 一紧急呼叫监测单元， 用于当监测到当前使用的交互通道出现终端 200对紧 急服务中心 600的呼叫时， 通过宽带通信模块 110或无线通信模块 120将本 地的信息向紧急服务中心 600发送。
本实施例的技术方案提供了一个能够实现准确定位和 VOIP 电话业务的 多业务宽带通信装置 100。 在正常工作状态下， 终端 200与宽带网络 300之 间的交互通道是连通的， 用户的语音流和数据流可以通过多业务宽带通信装 置 100在宽带网络 300中进行传输。 该装置既可以实现 VOIP电话业务， 又可 以在 VOIP电话业务失效的情况下， 使用无线通信模块 120通过无线网络 400 继续为用户提供电话业务， 即实现了电话业务。
当然， 根据装置的具体结构设置， 还可以实现基于宽带网络 300能够实 现的各种数据业务。 基于定位系统获取的地址信息可以有效地解决单纯无线 通信条件下因移动性带来的位置定位问题， 特别是在需要紧急救援情况下， 快速准确定位用户的位置非常有用。
本实施例的技术方案可以使运营商逐渐停建或废弃 PSTN/ ISDN700 网络 设备， 利用现有的宽带网络 300和无线网络 400, 能够降低运营成本， 也符 合 VOIP技术的发展趋势。
实施例五

步骤 10、 当监控模块监测到终端与宽带网络之间的交互通道失效时， 触 发切换模块；
步骤 20、 切换模块在监控模块触发时， 连通终端和无线网络之间的交互 通道。
本实施例的技术方案可以在监测到宽带网络实现的 VOIP 电话业务不可 用时， 控制切换至以无线网络来实现电话业务， 无须 PSTN/ IS匪网络设备即 能够为用户提供电话业务。 该技术方案有效的利用了已有的无线网络设备， 无须再维护 PSTN/ IS匪网络设备， 可逐渐予以淘汰， 从而降低运营成本。

在监控模块触发该切换模块之后， 还可以包括下述步骤：
监控模块周期性监测宽带通信模块实现的终端与宽带网络之间的交互通 道是否可用， 例如网络连通性是否恢复， 网络设备故障是否排除等， 若是， 则控制切换模块恢复切换前状态，从而断开终端与无线网络之间的交互通道， 且同时连通终端与宽带网络之间的交互通道。
上述技术方案保证优先以宽带网络来实现 VOIP电话业务。
在上述步骤 20中， 切换模块在监控模块触发时， 连通无线通信模块实现 终端和无线网络之间的交互通道具体包括：
当与用于插接电话作为终端的电话机接口相连的 SLIC单元，在电话机和 宽带网络之间的交互通道中传输语音数据时， 在监控模块触发 SLIC单元时， SLIC单元切换至在电话机和无线网络之间的交互通道中传输语音数据，其中， SLIC单元即相当于切换模块； 或
当与用于连接计算机作为终端的 IP端口相连的 IP数据处理单元， 在计 算机和宽带网络之间的交互通道中传输经 IP语音分组处理模块处理的 IP数 据时， 在监控模块触发 IP数据处理单元时， IP数据处理单元切换至在计算 机和无线网络之间的交互通道中传输经 IP语音分组处理模块处理的 IP数据， 其中， IP数据处理单元即相当于切换模块。
釆用上述技术方案， 可以通过特定的一个电路将无线通信模块和宽带通 信模块连接到电话机上， 则可以有效地集成多业务宽带通信装置为一体， 便 于安装使用。
