Description

一种 IP多媒体子系统动态电话簿业务的实现方法及系统 技术领域
本发明涉及无线通讯领域， 尤其涉及在处于不支持 IP接入的网络中的 终端上， 实现 IP多媒体子系统（ IMS , IP Multimedia Subsystem )动态电话 簿业务的方法及系统。 背景技术
无线网络可以分为电路域（ CS Domain, Circuit Switch Domain )和分 组域（PS Domain, Packet Switch Domain ) , 对手机用户来说， 传统的业务 如语音、 短信（SMS, Short Messaging Service )等均由无线网络的电路域 来提供服务；而例如无线应用通讯协议（ WAP , Wireless Application Protocol ) 上网、 彩信等业务则需要由无线网络的分组域来提供服务， 即向用户提供 IP接入的服务。 纯 CS域网络指网络不提供分组域业务， 也就是不提供 IP 接入的能力， 具体规定可以参考无线通讯领域的相关文献。
在第三代移动通信技术（3G, 3rd Generation ) 的无线通讯网络中， 各 种网络的互联互通有了很大的进步， 尤其是 IMS应用的引入， 使得无线网 和互联网的网内和网间用户的连通变得简单。 关于 IMS的定义， 可参考国 际标准第三代合作伙伴计划 （ 3GPP, 3rd Generation Partnership Project ) 的 文件或者其他无线通讯领域的参考文献。
在国际通用移动通信系统 ( UMTS , Universal Mobile Telecommunica- tions System ) 3GPP标准规定的 IMS各种业务中， IMS动态电话簿具有像 一般手机的电话簿一样进行管理联系人信息的功能如添加、 删除、 更改等 等， 而且在带有 IMS动态电话簿功能的手机或者其他终端上， 用户还可以 看到自己 IMS动态电话簿中联系人的状态， 如目标联系人是否在线、 是否 繁忙、 是否期望的通讯方式等状态 （类似于互联网的即时通讯工具如 MSN 或 QQ 中的在线、 离线、 忙碌、 免打扰等用户状态） ， 用户可根据对方的 状态选择相应的联系方式， 在 IMS的术语中， 这种技术称为呈现或呈现服 务。
IMS动态电话簿还有一个与普通电话簿的不同处， 即 IMS动态电话簿 中的联系人信息不仅在终端本地有， 也存在于网络侧的服务器上， 在 IMS 的术语中， 称为组管理。
IMS 动态电话簿主要需要的呈现服务和组管理服务都是通过会话初始 协议（SIP, Session Initiation Protocol )信令和可扩充标记语言配置接入协 议（ XCAP, XML Configuration Access Protocol )来实现的， SIP信令和 XCAP 协议属于 3GPP等相关标准组织制定的标准协议（在此不做具体描述）， 这 两个协议都是要依靠 IP协议进行的， 即都要求无线网络能提供分组域业务 的能力即无线网络有让手机等无线终端以 IP方式接入的能力。 而在没有 IP 接入服务提供的网络， IMS动态电话簿的功能是无法使用的。
目前， 由于为原有的纯 CS域的无线网络增加 IP接入能力， 涉及庞大 的设备升级费用问题， 因此， 不是所有的无线网络都支持分组业务， 比如 一些远郊农村地区， 大部分没有向用户提供分组业务也就是没有 IP接入能 力的； IMS手机用户在不支持 IP接入的网络中时，或者从支持 IP接入的网 络移动到不支持 IP接入的网络中时（如从城市网络移动到农村网络时），将 不能使用 IMS动态电话簿功能， 给用户的使用带来不便。 发明内容
本发明的主要目的在于提供一种 IP多媒体子系统动态电话簿业务的实 现方法， 使 IMS用户在不支持 IP接入的网络中仍能够使用 IMS动态电话 簿的功能， 增强用户体验。
本发明的另一目的在于提供一种 IP多媒体子系统动态电话簿业务的实 现系统， 使 IMS用户在不支持 IP接入的网络中仍能够使用 IMS动态电话 簿的功能， 增强用户体验。
为了解决上述问题， 本发明提供了一种 IP多媒体子系统动态电话簿业 务的实现方法， 包括：
终端将 IP多媒体子系统动态电话簿业务数据包承载在短消息中， 传递 给 IP多媒体子系统；
所述 IP多媒体子系统将 IP多媒体子系统动态电话簿业务数据包承载在 短消息中， 传递给终端。
进一步地， 所述将 IP多媒体子系统动态电话簿业务数据包承载在短消 息中为： 将所述 IMS动态电话簿业务数据包以短消息报文的方式构造一个 或一个以上短消息。
进一步地， 在所述每个短消息中增加标识动态电话簿电路域扩展的前 缀字符串； 或者， 在所述每个短消息的协议标识字段中标识该短消息为动 态电话簿电路域扩展的短消息。
在所述同属于一个 IP多媒体子系统动态电话簿业务数据包的第一个短 消息和最后一个短消息中， 分别设置标识该短消息为第一个短消息或最后 一个短消息的标志。

图 1为本发明中实现 IP多媒体子系统动态电话簿的系统组成结构的示 意图；
图 2为本发明中的终端在不支持 IP接入的网络中发送 IDCOC消息的 流程示意图；
图 3为本发明中的终端在不支持 IP接入的网络中接收 IDCOC消息的 流程示意图。 具体实施方式
需要承载 IMS动态电话簿的呈现服务和组管理服务的 SIP和 /或 XCAP 都是文本格式的协议， 可以用短消息 （SMS, Short Message Service ) 来承 载。 本文中就是使用短消息来承载 SIP信令和 /或 XC AP协议， 实现 IMS动 态电话簿的 IMS组管理服务和呈现服务的业务内容， 本文中将基于短消息 扩展 IMS 动态电话簿可使用的范围称作 IMS 动态电话簿电路域扩展 ( IDCOC , IMS Dynamic Contact Over Circuit ) , 以达到扩展 IMS动态电话 簿在无 IP接入服务网络中同样可用的目的，使手机中的 IMS动态电话簿在 无 IP接入服务网络下也可使用， 适用于 IMS网络和无 IP接入业务网络间 的业务连接。承载 IDCOC内容的短消息在本文中称为 IMS动态电话簿电路 域扩展短消息（ IDCOC SMS )。 另外， 因为短消息在网络中占用资源较少， 即使对于要求 IMS动态电话簿中要求永久在线的用户， 本发明提供的技术 方案也不会导致网络拥塞。
图 1为本发明中实现 IP多媒体子系统动态电话簿的系统组成结构的示 意图， 如图 1所示， 本发明中在不支持 IP接入的网络中实现 IMS动态电话 簿的系统包括：拥有 IMS动态电话簿的终端， CS网络中的短消息中心（SC, Short Message Center ) , IMS 网络中的 IP 多媒体网关 （IM-MGW, IP Multimedia-Media Gateway )和动态电话簿服务器 （包括组管理服务器和呈 现服务器） 。 其中，
拥有 IMS动态电话簿的终端，用于在其处于不支持 IP接入的网络中时， 将 IMS 动态电话簿业务数据包承载在短消息中， 并利用该短消息完成与 IMS系统之间的 IMS动态电话簿业务的信息交互；
终端在发送 IMS动态电话簿业务数据包时， 将所述 IMS动态电话簿业 务数据包以短消息报文的方式构造为一个或多个短消息发送至 IP多媒体网 关；
还用于在接收 IMS动态电话簿业务数据包时， 从接收到的短消息中提 取出 IMS动态电话簿业务的数据包； 还用于在将 IMS动态电话簿业务数据包以短消息报文的方式构造为一 个或多个短消息时， 在每个短消息中增加标识动态电话簿电路域扩展的前 缀字符串或在短消息的协议标识字段中标识此短消息为动态电话簿电路域 扩展的短消息；
还用于在发送短消息时， 将短消息中的目的地址设置为所述 IP多媒体 网关；
还用于在开机时检测到其处于不支持 IP接入的网络中时， 或者从支持 IP接入的网络移动到不支持 IP接入的网络中时， 向所述 IP多媒体网关发 送承载有 IMS动态电话簿业务数据包的短消息； 所述 IMS动态电话簿业务 数据包中指示所述终端处于不支持 IP接入的网络中；
所述 IP多媒体网关， 实现电路交换向 IP分组交换在承载的转换， 以达 到与 CS域和公共交换电话网络（PSTN )互通； 用于从接收到的短消息中 提取出 IMS动态电话簿业务的数据包；
还用于将 IMS动态电话簿业务数据包以短消息报文的方式构造为一个 或多个短消息发送至终端；
还用于在将 IMS动态电话簿业务数据包以短消息报文的方式构造为一 个或多个短消息时， 在每个短消息中增加标识动态电话簿电路域扩展的前 缀字符串或在短消息的协议标识字段中标识此短消息为动态电话簿电路域 扩展的短消息；
还用于在发送短消息时， 将短消息中的目的地址设置为所述终端； 还 用于接收从终端发送的短消息中解析出 IMS动态电话簿业务数据包， 且此 数据包中包含终端处于不支持 IP接入的网络中的指示时， 获知终端处于不 支持 IP接入的网络。
所述短消息中心， 用于接收所述终端发送的短消息后， 根据其目的地 址将接收到的短消息转发至所述 IP多媒体网关；还用于接收所述 IP多媒体 网关发送的短消息后， 根据其目的地址将接收到的短消息转发至所述终端。 所述动态电话簿服务器， 用于在终端处于不支持 IP的网络中时， 发送 SIP和 /或 XCAP数据包时， 设置其路由为 IP多媒体网关。
上文中的 IMS动态电话簿业务数据包为会话初始协议数据包和 /或可扩 充标记语言配置接入协议数据包。
图 2为本发明中的终端在不支持 IP接入的网络中发送 IDCOC消息的 流程示意图， 如图 2所示， 当移动终端移动到无数据业务网络时， 则处于 IDCOC模式。 此模式下， 终端与 IMS网络的交互将通过 IDCOC短消息来 实现， 终端将待发送的 SIP和 /或 XCAP数据包拆分成一个序列的短消息， 以 IP多媒体网关为目的地址逐条发送给网络， IMS网络的 IM-MGW从收 到的 SMS中提取作为内容承载的 SIP和 /或 XCAP数据包发送至组管理与呈 现服务器， 具体包括以下步骤：
步骤 200 201 : 终端将需要向 IMS网络发送的 SIP和 /或 XCAP数据包 以 SMS "^文的方式构造为 IDCOC短消息发送至短消息中心。
终端在发送的 IDCOC短消息中指明其目的地址为 IMS网络的 IP多媒 体网关。
由于网络不支持 IP接入，终端不能以 IP ^艮文的形式将 SIP和 /或 XCAP 数据包发送至 IMS网络， 而是将数据包以拆分长度（为 SMS报文长度减去 前缀长度的值）为单位拆分为一个或多个数据段； 例如， 3GPP标准规定的 最大长度为 160 个英文字符， 而终端使用特定的前缀匹配字串例如 "〃IDCOC:，，作为 SMS报文的前缀用于指示其处于不支持 IP接入的网络中， 使终端和 IMS网络可明确的识别该 SMS为 IDCOC SMS , 则终端拆分数据 包的单位为 152。 对于大于拆分长度的 SIP和 /或 XCAP数据， 终端需发送 多 个短消 息 ， 并在最后一个短消 息之前的每个短消 息的 More-Messages-to-Send字段标志出此短消息是否是最后一个短消息。 SIP和 /或 XCAP数据包拆分后， 由多个短消息承载时， 本发明中终端指示此多个 短消息首尾的方式， 并不局限于上述一种， 只要是能够指明哪几个短消息 的承载了一个 SIP和 /或 XCAP数据包即可。
在其它实施例中， 终端除了在短消息报文的前缀部分携带系统设定的 字符串外， 还可以通过在其发送的短消息的协议标识（ Protocol-Identifier ) 字段中指明此短消息为 IDC0C短消息， 例如可以参考 3GPP 23.040 中在 Protocol-Identifier字段中定义 IDC0C的类型， 且本发明并不限于此两种方 式，只要是能够设定可使系统统一识别的用于指明此短消息为 IDC0C短消 息的方式均可。
步骤 202: 短消息中心接收到 IDC0C短消息后， 将其转发至短消息中 指示的目的地址即 IMS网络的 IP多媒体网关。
短消息中心对接收到的 IDC0C短消息的处理与其处理普通短消息的方 式相同， 只是按其目的地址转发即可， 所以本发明中不涉及对短消息中心 的任何改动。
步骤 203~204： IP 多媒体网关收到短消息后， 提取出短消息中携带的 SIP和 /或 XCAP数据包， 并发送至动态电话簿服务器。
多媒体网关根据短消息的前缀匹配字段或短消息的 Protocol-Identifier 字段识别此短消息为 IDC0C 短消息， 并通过判断短消息中的 More-Messages-to-Send 字段， 接收连续的一个或多个短消息， 直到接收到 的短消息中 More-Messages-to-Send字段指示此为最后一个短消息时， 将这 一序列的短消息中提取出 SIP或 XCAP数据包的内容（短消息中包含前缀 的， 去掉短消息中前缀后的数据内容） 。
步骤 205: 动态电话簿服务器接收 SIP和 /或 XCAP数据包， 对终端的 动态电话簿信息进行相应处理， 完成从终端到动态电话簿服务器的 SIP和 / 或 XCAP数据包传输。 对动态电话簿服务器而言， 从多媒体网关接收到的 SIP和 /或 XCAP数 据包与存在于 IMS网络下用户发送的数据包无差别。
图 3为本发明中的终端在不支持 IP接入的网络中接收 IDCOC消息的 流程示意图， 如图 3所示， 终端在不支持 IP接入的网络接收 IDCOC消息 的方法包括以下步骤：
步骤 300 301 : 终端处于不支持 IP接入的模式下时， 动态电话簿服务 器将要发送的 SIP和 /或 XCAP数据包中路由服务器的地址设置为 IP多媒体 网关， 向 IP多媒体网关发送 SIP和 /或 XCAP数据包。
步骤 302~303： IP多媒体网关将接收到 SIP和 /或 XCAP数据包以 SMS "^文的方式构造为 IDCOC短消息发送至短消息中心。
IP 多媒体网关构造 IDCOC 短消息的方式与步骤 201 中终端构造 IDCOC短消息的方式相同， 且 IP多媒体网关在发送的 IDCOC短消息中指 明其目的地址为所述终端。
步骤 304: 短消息中心接收到 IDCOC短消息后， 将其转发至短消息中 指示的目的地址即处于 IDCOC模式的终端。
短消息中心对接收到的 IDCOC短消息的处理与其处理普通短消息的方 式相同， 只是按其目的地址转发即可。
步骤 305: 终端收到 IDCOC短消息后， 从短消息中提取出携带的 SIP 和 /或 XCAP数据包， 完成从动态电话簿服务器到终端的 SIP和 /或 XCAP 数据包传输。
终端从 IDCOC短消息中解析出 SIP和 /或 XCAP数据内容的方式与步 骤 203中， IP多媒体网关解析 SIP和 /或 XCAP数据内容的方式相同。
上述描述的方法中， 终端向动态电话簿服务器发送 SIP和 /或 XCAP数 据后， 动态电话簿服务器向终端返回响应消息时， 釆用图 3 所示的流程返 回携带有响应内容的 SIP或 XCAP数据包。 动态电话簿服务器向终端发送 SIP或 XCAP数据后， 终端向动态电话簿服务器返回响应消息时， 釆用图 2 所示的流程返回携带有响应内容的 SIP或 XCAP数据包。
终端开机时检测到其处于不支持 IP接入的网络中时，或者从支持 IP接 入的网络移动到不支持 IP接入的网络中时， 向 IM-MGW发送 IDCOC模式 启动消息，在 SIP或 XCAP数据包中携带标志终端处于 IDCOC模式的信息， 发送至动态电话簿服务器， 发送的流程与图 2所示的相同。 终端开机从不 支持 IP接入的网络移动到支持 IP接入的网络中时，向 IM-MGW发送 IDCOC 模式结束消息， 在 SIP或 XCAP数据包中携带标志终端处于 IP接入状态模 式的信息， 发送至动态电话簿服务器， 发送的流程与图 2所示的相同。
本发明同时解决了 SIP与 ISDN的地址映射（表示为 SIP--ISDN )问题， 因为 IMS网络中以 SIP为地址， 在 CS域中以 ISDN为地址， IM-MGW是 沟通 CS域和 IMS的桥梁， 由 IM-MGW维护 SIP--ISDN的地址映射表。 本 发明中 IM-MGW同时完成了 SIP--ISDN的地址转换的问题。
本发明中使用本方法的业务计费方式， 可以为包月形式， 以减少消费 者使用本发明中方法所带来的短信消费费用。
本发明还可有其他多种实施例， 在不背离本发明精神及其实质的情况 这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
