Description

因特网协议多媒体子系统终端接入网络的方法及装置 技术领域 本发明涉及通信领域， 具体而言， 涉及一种因特网协议多媒体子系统终端接入网 络的方法及装置。 背景技术 因特网协议多媒体子系统（IP Multimedia Subsystem, 简称为 IMS)网络要求 IMS 终端可像移动无线终端一样可实现漫游控制接入， 减少用户在移动 IMS终端时的开销 户、 移机或改号等操作。 用户在营业厅开户时会生成一个用户名和密码， 用户拿着终端上电后手工在终端 界面输入用户名、 密码。 用户输入用户名、 密码后到控制系统进行登录注册。 如果用 户在控制系统未开户， 或用户名、 密码错误， 或终端处于漫游状态则控制系统直接向 终端返回注册失败的消息。 现有 IMS终端管理系统根据终端接入的因特网协议（Internet Protocol,简称为 IP) 地址与该系统配置的数据进行判断比较， 如果判断条件不匹配则系统判断为该终端超 过漫游控制， 不允许登录和下发登录 IMS核心网的配置信息。 现有 IMS终端管理系统漫游控制及数据配置方法如下： 在系统上配置该系统可控制的区域的所有地区， 地区配置可按照国、 省、 市、 区 县共四级配置， 在每级地区的每个地区都配置该地区的 IP网段。 同时， 配置一个或多 个非控制区域， 并设置这一个或多个非控制区域的 IP网段。在终端账户上设置该终端 账户的漫游控制策略。 终端在出厂时会根据 IMS运营商的要求，统一设置 IMS终端管理系统的域名地址， 终端在任何地方开机注册时， 都按照设置的域名到 IMS终端管理系统进行注册和获取 IMS业务配置信息。 终端在 IMS终端管理系统注册时会获取接入地的 IP地址， 系统根据终端的账户、 密码获取终端账户信息的漫游控制策略，系统根据注册接入地的 IP地址与地区上配置 的 IP地址进行匹配以获取地区信息， 进而用终端账户的漫游控制策略与获取的地区、 开户地区进行匹配判断， 如果不满足漫游控制策略则注册失败。 终端设备在 IMS 网络漫游有两种控制方式： 网络协议连接访问网络 （Internet Protocol Connectivity Access Network, 简称为 IP-CAN) 漫游和 IMS漫游。 其中， IP-CAN漫游实际是终端设备通过网络接入到归属地的 IMS网络。
IMS 漫游接入分为通用无线分组业务 （General Packet Radio Service, 简称为 GPRS)、 第 3代移动通信 （The Third Generation Mobile Communications, 简称为 3G) 方式接入和无线局域网 （Wireless Local Area Network, 简称为 WLAN) 无线、 电缆 / 数字用户线 （cable/Digital Subscriber Line, 简称为 cable/xDSL) 有线方式接入。
GPRS和 3G接入方式可附着在 IP-CAN网络通过服务通用分组无线业务支撑节点 (Serving General packet radio service support node, 简称为 SGSN) 注册到 IMS网络。 WLAN和 cable/xDSL方式通过动态主机配置协议 （Dynamic Host Configure Protocol, 简称为 DHCP) 服务器发现代理呼叫会话控制功能实体 （Proxy-Call Session Control Function, 简称为 P-CSCF) 域名， 域名服务 （Domain Name Server, 简称为 DNS) 解 析 P-CSCF域名并返回给终端， 终端根据 P-CSCF地址接入 IMS网络。 在已有 IMS终端管理系统中分为两种漫游方式： 管理系统内跨地漫游和管理系统 外的跨管理系统漫游。 图 1是根据相关技术的 IMS终端漫游接入网络的示意图， 如图 1所示， 1表示当今的计算机网络， 2表示 IMS终端管理系统 1控制的区域范围， 3表 示 IMS终端管理系统 2控制的区域范围， 4表示 IMS终端管理系统 1， 5表示 IMS终 端管理系统 2， 6表示从区 1漫游到区 b的过程， 7表示终端 （Terminal Station, 简称 为 TS)通过计算机网络到 IMS终端管理系统 1进行注册过程， 8表示终端 TS接收 IMS 终端管理系统 1下发的配置信息。 下面结合图 1描述上述两种漫游方式。 管理系统内跨地漫游： 终端 TS在 IMS终端管理系统 1的控制区域内从区 1漫游 到区 2时， IMS终端管理系统 1根据终端接入的 IP地址判断用户在区 2鉴权通过， IMS 终端管理系统 1下发区 2上配置的 IMS代理服务器地址信息， TS根据下发的 IMS代 理服务器地址信息就近接入。 管理系统外的跨管理系统漫游： 终端 TS在 IMS终端管理系统 1控制的区 1漫游 到 IMS终端管理系统 2控制的区 b， 终端 TS到其归属地的 IMS终端管理系统 1进行 注册， IMS终端管理系统 1根据 IMS终端接入的 IP地址判断漫游地区域不在本系统 管辖区内， 以 IP地址匹配归属地管理系统保存的数据， 获取一个代理接入点基站控制 器 （Base Station Controller, 简称为 BSC) 信息和业务信息下发给 TS。 根据现有 IMS终端管理系统的漫游控制方法和 IMS网络漫游方法存在如下问题: 首先， IMS终端管理系统无法准确配置异地接入代理点的地址等信息， 终端无法 获取准确的接入点。 其次，每个拜访网络 IMS网络域名不同， IMS终端管理系统的域名也不相同， IMS 终端设备初始化困难， 终端数据配置复杂， 不利于推广。 再次， IP-CAN漫游方式通过 IP网络直接接入归属地 IMS网络， 无法保证通信网 络服务质量（Quality of Server, 简称为 QOS)要求； IMS漫游的 WLAN和 cable/xDSL 接入方式需要修改 DHCP服务器， 不通过 DHCP接入网络 IMS终端无法接入 IMS网 络。 最后， 不能提供终端开通业务漫游管理。 针对相关技术中终端无法获取准确的接入点和不能提供终端开通业务漫游管理的 问题， 目前尚未提出有效的解决方案。 发明内容 本发明提供了一种因特网协议多媒体子系统 IMS终端接入网络的方法及装置， 以 至少解决相关技术中终端无法获取准确的接入点和不能提供终端开通业务漫游管理的 问题。 根据本发明的一个发明， 提供了一种 IMS终端接入网络的方法， 包括： IMS终端 的归属地 IMS终端管理系统从 IMS终端的拜访地 IMS终端管理系统获取拜访地的 IMS 网络接入点信息，其中， IMS终端管理系统之间通过接口同步各自的数据；归属地 IMS 终端管理系统向 IMS终端发送配置信息，其中，配置信息包括获取的 IMS网络接入点 信息。 优选地， IMS终端的归属地 IMS终端管理系统从 IMS终端的拜访地 IMS终端管 理系统获取拜访地的 IMS网络接入点信息包括： 归属地 IMS终端管理系统接收 IMS 终端的注册请求；归属地 IMS终端管理系统根据注册请求从拜访地 IMS终端管理系统 获取拜访地的 IMS网络接入点信息。 优选地，归属地 IMS终端管理系统根据注册请求从拜访地 IMS终端管理系统获取 拜访地的 IMS网络接入点信息包括：归属地 IMS终端管理系统根据注册请求认证 IMS 终端合法后，根据 IMS终端连接的因特网协议 IP地址确定拜访地 IMS终端管理系统； 归属地 IMS终端管理系统向拜访地 IMS终端管理系统发送 IMS网络接入点信息请求 消息； 归属地 IMS终端管理系统接收来自拜访地 IMS终端管理系统的 IMS网络接入 点信息和拜访地的业务信息。 优选地，在归属地 IMS终端管理系统向 IMS终端发送配置信息之前，上述方法还 包括:归属地 IMS终端管理系统根据 IMS终端的预定策略整合拜访地的业务信息、 IMS 网络接入点信息和归属地 IMS终端管理系统本地保存的 IMS终端开通的业务信息，并 生成配置信息。 优选地， 如果 IMS终端存在多个不同的账户， IMS终端已经成功注册到一个账户 的归属地 IMS终端管理系统后， 使用与该账户归属地不同的当前账户进行注册时， 在 IMS终端的归属地 IMS终端管理系统从拜访地 IMS终端管理系统获取拜访地的 IMS 网络接入点信息之前，上述方法还包括： 已注册的 IMS终端管理系统接收 IMS终端的 注册请求， 并根据注册请求确定当前账户的归属地 IMS终端管理系统； 已注册的 IMS 终端管理系统向当前账户的归属地 IMS终端管理系统发起身份认证请求； 如果认证成 功，则已注册的 IMS终端管理系统从当前账户的归属地 IMS终端管理系统获取当前账 户的业务信息，并从拜访地 IMS终端管理系统获取拜访地的 IMS网络接入点信息；如 果认证不成功， 则注册结束， IMS终端断开与已注册的 IMS终端管理系统的连接。 优选地， 如果 IMS终端存在多个不同的账户， IMS终端已经成功注册到一个账户 的归属地 IMS终端管理系统后， 使用与该账户归属地不同的当前账户进行注册时， 在 IMS终端的归属地 IMS终端管理系统从拜访地 IMS终端管理系统获取拜访地的 IMS 网络接入点信息之前，所述方法还包括： 已注册的 IMS终端管理系统接收 IMS终端的 注册请求， 并根据注册请求确定当前账户的归属地 IMS终端管理系统； 已注册的 IMS 终端管理系统向 IMS终端下发当前账户的归属地 IMS终端管理系统的域名信息；当前 账户的归属地 IMS终端管理系统接收到 IMS终端的注册请求。 优选地， 如果归属地 IMS终端管理系统获取 IMS网络接入点信息失败， 归属地 IMS终端管理系统直接下发归属地的 IMS网络接入点信息给 IMS终端， IMS终端根 据归属地的 IMS网络接入点信息接入 IMS网络。 优选地， IMS终端管理系统配置自身的所有终端的账户信息、 业务数据、 管辖 IP 网段， 并配置对应的一个或多个 IMS终端管理系统的域名、 管辖 IP网段、 系统特征 码。 优选地， 在归属地 IMS终端管理系统从拜访地 IMS终端管理系统获取拜访地的 IMS网络接入点信息之前， 上述方法还包括： IMS终端管理系统接收来自其它 IMS终 端管理系统的同步更新数据请求， 并检查请求同步的数据的合法性； 若请求同步的数 据合法， 则 IMS终端管理系统检查请求同步的数据与自身的现有数据是否冲突； 若请 求同步的数据不合法， IMS终端管理系统向其它 IMS终端管理系统返回失败信息； 若 请求同步的数据与现有数据没有冲突，则 IMS终端管理系统自动更新请求同步的数据;

( 1 ) 当前账户的归属地 IMS终端管理系统负责验证身份， 并返回信息给已注册 账户的 IMS终端管理系统，由已注册账户的 IMS终端管理系统获取拜访地的接入点信 息，该方式可以通过以下步骤实现：在 IMS终端的归属地 IMS终端管理系统从拜访地 IMS终端管理系统获取拜访地的 IMS网络接入点信息之前，已注册的 IMS终端管理系 统接收 IMS终端的注册请求，并根据注册请求确定当前账户的归属地 IMS终端管理系 统;已注册的 IMS终端管理系统向当前账户的归属地 IMS终端管理系统发起身份认证 请求； 如果认证成功，则已注册的 IMS终端管理系统从当前账户的归属地 IMS终端管 理系统获取当前账户的业务信息， 并从拜访地 IMS 终端管理系统获取拜访地的 IMS 网络接入点信息； 如果认证不成功， 则注册结束， IMS终端断开与已注册的 IMS终端 管理系统的连接。此处， 已注册的 IMS终端管理系统向 IMS终端发送业务信息以及接 入点信息， IMS终端可以据此接入 IMS网络， 并根据业务信息使用业务。 ( 2 ) IMS终端通过已注册账户的 IMS终端管理系统获取当前账户的归属地 IMS 终端管理系统的域名信息，由当前账户的 IMS终端管理系统获取拜访地的接入点信息， 该方式可以通过以下步骤实现:在 IMS终端的归属地 IMS终端管理系统从拜访地 IMS 终端管理系统获取拜访地的 IMS网络接入点信息之前，已注册的 IMS终端管理系统接 收 IMS终端的注册请求， 并根据注册请求确定当前账户的归属地 IMS终端管理系统； 已注册的 IMS终端管理系统向 IMS终端下发当前账户的归属地 IMS终端管理系统的 域名信息； 当前账户的归属地 IMS终端管理系统接收到 IMS终端的注册请求。 此处， IMS终端直接注册到当前账户的归属地 IMS终端管理系统， 由当前账户的归属地 IMS 终端管理系统从拜访地 IMS终端管理系统获取接入点信息， IMS终端可以根据当前账 户的归属地 IMS终端管理系统发送的接入点信息接入 IMS网络，并根据业务信息使用 业务。 上面提供了 IMS终端存在多账户注册 IMS终端管理系统时的两种优选处理方式， 实际运用中可以根据需求选择处理方式， 比较灵活， 提高了 IMS终端管理系统的实用 性。 在上述的步骤中， 如果归属地 IMS终端管理系统获取 IMS网络接入点信息失败， 归属地 IMS终端管理系统直接下发归属地的 IMS网络接入点信息给 IMS终端， IMS 终端根据归属地的 IMS网络接入点信息接入 IMS网络。 该方法在 IMS终端管理系统 运行不稳定时， 提供了一种解决方式， 使得 IMS终端管理系统能够继续提供服务， 提 高了 IMS终端管理系统的可用性。 为了更好的实现 IMS终端接入网络， 在步骤 S202之前， 还可以包括以下步骤：
IMS终端管理系统配置自身的所有终端的账户信息、业务数据、 管辖 IP网段， 并配置 对应的一个或多个 IMS终端管理系统的域名、 管辖 IP网段、 系统特征码。 该方法可 以便于 IMS终端设备的初始化和 IMS终端设备的数据配置， 为不同的 IMS终端管理 系统之间进行数据同步提供了支持。 由于每个 IMS网络的域名不同， IMS终端管理系统的域名也不相同，往往导致 IMS 终端设备初始化困难， IMS终端设备数据配置复杂， 因此提供了一种较优的方式来解 决上述问题，该方式是在归属地 IMS终端管理系统从拜访地 IMS终端管理系统获取拜 访地的 IMS网络接入点信息之前，还包括： IMS终端管理系统接收来自其它 IMS终端 管理系统的同步更新数据请求， 并检查请求同步的数据的合法性； 若请求同步的数据 合法， 则 IMS终端管理系统检查请求同步的数据与自身的现有数据是否冲突； 若请求 同步的数据不合法， IMS终端管理系统向其它 IMS终端管理系统返回失败信息； 若请 求同步的数据与现有数据没有冲突， 则 IMS终端管理系统自动更新请求同步的数据； 若请求同步的数据与现有数据有冲突，则 IMS终端管理系统向其它 IMS终端管理系统 发送冲突的节点信息， 其它 IMS终端管理系统调整数据后重新进行数据的同步。 该方 法实现了不同的 IMS终端管理系统之间进行数据同步，便于 IMS终端设备初始化和数 据配置， 有利于 IMS网络的拓展和应用。 其中，在 IMS终端管理系统接收到来自其它 IMS终端管理系统的同步更新数据请 求之前， 还可以包括： IMS终端管理系统自检 IP网段是否冲突， 如果不冲突， 拆分 IP 网段并生效。该方法有利于不同的 IMS终端管理系统之间进行数据同步。实际应用中， 可以由 IMS终端管理系统自动拆分 IP网段。 需要指出的是， 上述内容中的 IMS网络接入点信息可以是与 IMS终端接入的 IP 地址对应的 BSC地址信息。 本发明实施例还提供了一种 IMS终端接入网络的装置， 该装置可以设置为实现上 述 IMS终端接入网络的方法。图 3是根据本发明实施例的 IMS终端接入网络的装置结 构框图， 如图 3所示， 该装置包括： 获取模块 32和发送模块 34， 其中， 获取模块 32， 设置为从 IMS终端的拜访地 IMS终端管理系统获取拜访地的 IMS网络接入点信息， 其中， IMS终端管理系统之间通过接口同步各自的数据； 发送模块 34， 耦合至获取模 块 32， 设置为向 IMS终端发送配置信息， 其中， 配置信息包括获取的 IMS网络接入 点信息。 通过上述装置， 获取模块 32从 IMS终端的拜访地 IMS终端管理系统获取拜访地 的 IMS网络接入点信息， 其中， IMS终端管理系统之间通过接口同步各自的数据； 发 送模块 34向 IMS终端发送配置信息， 其中， 配置信息包括获取的 IMS网络接入点信 息， 解决了相关技术中终端无法获取准确的接入点和不能提供终端开通业务漫游终端 管理的问题，进而达到了 IMS终端选择的 IMS网络接入点更准确，实现了业务漫游终 端管理以及提高 IMS网络安全性的效果。 图 4是根据本发明实施例的 IMS终端接入网络的装置的优选结构框图一， 如图 4 所示， 该装置除具有图 3所示所有模块外， 还可以包括： 整合模块 36和生成模块 38， 其中， 整合模块 36， 耦合至获取模块 32， 设置为根据 IMS终端的预定策略整合拜访 地的业务信息、 IMS网络接入点信息和归属地 IMS终端管理系统本地保存的 IMS终端 开通的业务信息； 生成模块 38， 耦合至整合模块 36， 设置为生成配置信息。 优选地， 获取模块 32包括： 第一接收单元， 设置为接收 IMS终端的注册请求； 获取单元， 耦合至第一接收单元， 设置为根据注册请求从拜访地 IMS终端管理系统获 取拜访地的 IMS网络接入点信息。 优选地， 获取模块 32还包括： 确定单元， 设置为根据注册请求认证 IMS终端合 法后， 根据 IMS终端连接的因特网协议 IP地址确定拜访地 IMS终端管理系统； 发送 单元，耦合至确定单元，设置为向拜访地 IMS终端管理系统发送 IMS网络接入点信息 请求消息； 第二接收单元， 耦合至发送单元， 设置为接收来自拜访地 IMS终端管理系 统的 IMS网络接入点信息和拜访地的业务信息。 优选地， 如果 IMS终端存在多个不同的账户， IMS终端已经成功注册到一个账户 的归属地 IMS终端管理系统后， 使用与该账户归属地不同的当前账户进行注册时， 此 时， 上述装置所属的 IMS终端管理系统作为已注册账户的系统， 上述装置还包括： 第 一接收模块， 设置为接收 IMS终端的注册请求， 并根据注册请求确定当前账户的归属 地 IMS终端管理系统； 发起模块， 耦合至第一接收模块， 设置为向当前账户的归属地 IMS终端管理系统发起身份认证请求； 第一处理模块， 耦合至发起模块， 设置为在认 证成功的情况下， 从当前账户的归属地 IMS终端管理系统获取当前账户的业务开通信 息，并从拜访地 IMS终端管理系统获取拜访地的 IMS网络接入点信息；如果认证不成 功， 则注册结束， IMS终端断开与已注册的 IMS终端管理系统的连接。 优选地， 如果 IMS终端存在多个不同的账户， IMS终端已经成功注册到一个账户 的归属地 IMS终端管理系统后， 使用与该账户归属地不同的当前账户进行注册时， 此 时， 上述装置所属的 IMS终端管理系统作为已注册账户的系统， 上述装置还包括： 第 二接收模块， 设置为接收 IMS终端的注册请求， 并根据注册请求确定当前账户的归属 地 IMS终端管理系统； 下发模块， 耦合至第二接收模块， 设置为向 IMS终端下发当前 账户的归属地 IMS终端管理系统的域名信息；此时， 当前账户的归属地 IMS终端管理 系统接收 IMS终端的注册请求。 优选地， 如果归属地 IMS终端管理系统获取 IMS网络接入点信息失败， 归属地 IMS终端管理系统直接下发归属地的 IMS网络接入点信息给 IMS终端， IMS终端根 据归属地的 IMS网络接入点信息接入 IMS网络。 优选地， IMS终端管理系统配置自身的所有终端的账户信息、 业务数据、 管辖 IP 网段， 并配置对应的一个或多个 IMS终端管理系统的域名、 管辖 IP网段、 系统特征 码。 优选地， 上述装置还包括： 同步模块， 设置为接收来自其它 IMS终端管理系统的 同步更新数据请求， 并检查请求同步的数据的合法性； 第二处理模块， 耦合至同步模 块， 设置为在请求同步的数据合法的情况下， 检查请求同步的数据与自身的现有数据 是否冲突； 在请求同步的数据不合法的情况下， 向其它 IMS终端管理系统返回失败信 息； 更新模块， 耦合至第二处理模块， 设置为在请求同步的数据与现有数据没有冲突 的情况下， 自动更新请求同步的数据； 第二发送模块， 设置为在请求同步的数据与现 有数据有冲突的情况下， 向其它 IMS 终端管理系统发送冲突的节点信息， 其它 IMS 终端管理系统调整数据后重新进行数据的同步。 需要说明的是， 装置实施例中描述的 IMS终端接入网络的装置对应于上述的方法 实施例， 其具体的实现过程在方法实施例中已经进行过详细说明， 在此不再赘述。 为了使本发明的技术方案和实现方法更加清楚， 下面将结合优选的实施例对其实 现过程进行详细描述。 优选实施例一 本优选实施例中， IMS终端的漫游控制和数据智能调整方法如下： 在 IMS终端管理系统间增加数据通信双向同步接口， 该接口用于系统间的管理的 IP网段同步和信息获取。

IMS终端到 IMS终端管理系统注册可有两种方式： 一种是就近进入漫游地（即拜 访地） IMS终端管理系统，另一种是通过归属地接入漫游地 IMS终端管理系统。其中， 对于第一种方式，如果 IMS终端可就近接入拜访地的 IMS终端管理系统，拜访地 IMS 终端管理系统根据终端的注册请求到归属地的 IMS终端管理认证合法性， 身份合法则 从归属地获取该账户的业务信息。对于第二种方式，如果 IMS终端到归属地 IMS终端 管理系统注册， 归属地 IMS终端管理系统认证合法后，则拜访地 IMS终端管理系统根 据终端注册信息到拜访地 IMS终端管理系统获取该地区业务信息和 IMS接入点 BSC 信息。 终端接入的 IMS终端管理系统根据策略整合获取的信息和本地保存的信息， 并下 发整合后的信息给 IMS终端， IMS终端根据信息接入 IMS网络和使用开通的业务。 通过上述步骤，所有 IMS终端通过 IMS终端管理系统获取 IMS网络最佳接入点， 终端接入网络方式没有任何限制， 解决了 IMS 终端漫游接入点不准确， 使获取 IMS 网络接入点更加准确； 采用在 IMS终端管理系统间增加数据通信双向同步接口， 解决 了终端注册设置复杂的问题， 使终端注册设置更加简单， 终端实现也更加简单； 解决 了固定 IP地址网络不能接入和业务不能漫游管理的问题，实现了漫游管理，更利于 IMS 软终端设备研发， 更利于 IMS网络推广使用； 并且， IMS终端管理系统域名对终端开 放， IMS核心网等所有信息不开放， 提高了 IMS网络的安全性。 优选实施例二 图 5是根据本发明优选实施例二的 IMS终端管理系统的结构框图， 如图 5所示， 该系统包括： 终端接口模块 502、 外部网元接口模块 504、 数据调度模块 506、 数据存 储模块 508和数据管理模块 510。 其中， 外围与终端接口模块 502和外部网元接口模 块 504对接的网元包括： 注册的各种终端、 归属地开销户系统 512 (又称为客户关系 管理系统， Customer Relationship Management, 简称为 CRM)和对端异地 IMS终端管 理系统 514，注册的各种终端可以包括：硬终端 516，手机软终端 518和 PC软终端 520。 其中， 终端接口模块 502设置为实现对硬终端 516、手机软终端 518和 PC软终端
