基于 IMS的家庭网关及其配置方法和
终端配置服务器及本地化入口点检测方法 技术领域
本发明涉及基于 IP多媒体子系统( IP Mul t imed ia Subsys tem,简称 IMS ) 的家庭网关及其配置方法, 特别涉及能够本地化接入 IMS 网络、 并通过 IMS 网络实现用户对家电的相关业务参数的配置的基于 IP 多媒体子系统的家庭 网关及其配置方法。
本发明还涉及 IMS终端配置服务器及 IMS本地化入口点检测方法, 特 别涉及能够根据用户输入的信息, 灵活高效地为 IMS 终端提供本地化的 IMS入口服务, 且具有广泛适用性的 IMS终端配置服务器及 IMS本地化入 口点检测方法。 背景技术
随着网络技术与信息家电产业的发展, 家庭的智能化和网络化逐渐成为 了现实, 使得原有单纯的家电设备可以与网络连接, 从而产生了网络家电。 现在已经出现了各种关于智能家庭网络的研究, 这些研究大多是基于现有的 计算机网络技术将家庭内的各种家电和设备联网, 并通过家庭网关与外部网 络相连, 从而为人们提供各种丰富、 多样化、 个性化、 方便、 舒适、 安全和 高效的服务。 其中, 家庭网关对实现家庭的内部信息与外部信息的交换起重 要作用, 它是一种将所有外部接入网连接到家庭内部网络, 并将家庭内部网 络连接到外部网络的物理接口, 同时也是一种使住宅用户可以获得各种家庭 服务(包括现有的服务和未来可能出现的服务) 的平台; 它可以从不同的外 部网络接收通讯信号, 通过家庭网络传递信号给某个消费设备, 从而能够使 用户通过外部设备, 经由外部网络和家庭网关, 对家庭内部设备进行管理和 控制。 下一代网络的发展趋势是全 IP网络, IP多媒体子系统( IP Mul t imedia Subsys tem, 简称 IMS )应运而生。 IMS是第三代通用合作计划 ( 3GPP )在 R5 版本提出的支持 IP 多媒体业务的子系统, 其核心特点是采用会话发起协议 ( SIP ) , 并且具有与接入的无关性, 因此 IMS是向全 IP网业务体系迈进的 重要一步。 IMS的发展趋势是成为基于 SIP会话的通用平台, 从而为未来的 多媒体应用提供一个通用的业务平台, 并同时支持固定和移动的多种接入方 式, 实现固网和移动网的融合。 因此, 连接家庭内部网络与外部网络的家庭 网关, 也需要作为 IMS网络的通信端点 ( IMS终端) , 经由 IP连通接入网 ( IP Connect ivi ty Accses s Ne twrok, 简称 IP-CAN )接入 IMS 网络, 从 而能够利用 IMS网络承载各种家庭业务, 并使用户能够通过 IMS网络对家电 进行控制和配置。
对于从某些 IP - CAN (如专线、 ADSL、 WLAN等)接入的家庭网关, 其 所有 IMS业务信息都需要通过 SBC接入到 IMS网络。而对于从其他一些 IP - CAN (如 GPRS、 3G PS等)接入的家庭网关, 其 IMS业务信息可以不需 要经过 SBC,但仍需经过 P- CSCF接入 IMS网络。 为避免 IMS通信中消息的 路由迂回, 提高 IMS业务的服务质量和网络资源的利用效率, 家庭网关应 尽量通过本地化的 IMS网络入口网元 (即 SBC和 /或 P-CSCF )接入到 IMS 网络, 为此在家庭网关与 IMS网络的通信初始化过程中, 需要实现本地化 的 IMS入口服务配置,也即实现家庭网关从本地 SBC和 P-CSCF接入到 IMS 网络。 此外, 为更好地实现用户对家电相关业务的设置 (如: 输入订阅该 家庭网关的即时通信终端、 签约 /取消某些服务项目等), 也需要通过 IMS 网络实现对家庭网关的相关业务参数的设置。
IP 多媒体子系统 (IP Mu l t imedia Subsys tem, 简称 IMS ) 是第三代 通用合作计划( 3GPP )在 R5版本提出的支持 IP多媒体业务的子系统。 IMS 的核心特点是采用会话发起协议 (SIP ) , 并且具有与接入的无关性, 因 此 IMS是向全 IP网业务体系迈进的重要一步。 在网络融合的发展趋势下, 3GPP, ETSI 和 ITU-T都在研究基于 IMS 的网络融合方案, 目的是使 IMS 成为基于 SIP会话的通用平台, 从而为未来的多媒体应用提供一个通用的 业务平台, 并同时支持固定和移动的多种接入方式, 实现固网和移动网的 融合。
与软交换技术相比, IMS具有接入无关性, 这一特征也构成了 IMS的 核心技术优势。 IMS网络的通信端点 ( IMS终端) 与网络都是基于 IP的。 在 3GPP的规范中, 这是通过 IP连通接入网 ( IP Connectivity Accsess Netwrok, 简称 IP- CAN ) 来保证的。
IMS中最重要的功能实体是呼叫会话控制功能( Call Session Control Function, 简称 CSCF) , 负责对用户多媒体会话进行处理, 其功能包括多 媒体会话控制、 地址翻译以及对业务协商进行服务转换等。 代理呼叫会话 控制功能 (Proxy- CSCF, 简称 P-CSCF) 是 IP-CAN到 IMS的最先连接点, 位于访问域中。 从 SIP观点看, P- CSCF是作为一个出界、 入界的 SIP代理 服务器。 IMS终端的所有 SIP消息都需要通过 P-CSCF接入到 IMS核心控制 层网络。
会话边界控制器(Session Border Controller, 简称 SBC)是提供安全 可靠的 VoIP和其它丰富媒体业务的关键部分。 SBC主要部署于网络边缘, 确保实时 IP流的安全可靠地跨越网络。 SBC可以支持第二层 /第三层服务, 提供一种灵活、 开放的架构, 从而支持运营商之间的对等连接、 运营商接 入部署, 以及统一的或者分布式的信令通信。 对于从某些 IP- CAN (如专 线、 ADSL、 WLAN等)接入的 IMS终端,该 IMS终端的所有 IMS业务信息(控 制面的 SIP消息和用户面 IP媒体流) 都需要通过 SBC接入到 IMS网络。 而对于从其他一些 IP- CAN (如 GPRS、 3G PS等)接入的 IMS终端, 该 IMS 终端的 IMS业务信息可以不需要经过 SBC。
上述 SBC或 P- CSCF称为 IMS网络的入口网元。 为了避免 IMS通信的 控制面 SIP消息和用户面的路由迂回,提高 IMS业务的服务质量(Quality of Serv i ce , 简称 QoS ) 和网络资源的利用效率, IMS 终端应尽量通过本 地化的 IMS网络入口网元接入到 IMS网络, 为此在 IMS终端的通信初始化 过程中, 需要实现本地化的 IMS入口服务配置, 也即实现 IMS终端从本地 SBC和 P- CSCF接入到 IMS网络。
现有技术中, 为实现 IMS终端通信初始化过程中的本地化 IMS入口服 务, 通常采用以下方法:
方法一、 对于从 GPRS或 3G分组域接入的 IMS终端, 利用分组数据协 议(PDP ) 激活过程来实现。 IMS终端在向网络侧发起的 PDP激活请求中, 附带 P-CSCF地址请求, GPRS网关支持节点 ( Ga teway GPRS Suppor t Node , 简称 GGSN )响应并回送本地 P-CSCF的 IP地址。 该 IMS终端根据该 IP地 址与该 P - CSCF建立通信连接。
该方法的不足之处为依赖于符合特定要求的 I P - CAN。 如果 IMS终端 当前所接入的 IP-CAN不能提供上述特定功能, 则 IMS终端无法通过 I P - CAN的初始化配置而获得 IMS网络的本地化入口服务。
方法二、 IMS终端所在的 IP- CAN使用动态主机分配协议(DHCP )和域 名服务协议 (DNS ) 功能来实现。 IMS终端首先向网络侧发起 DHCP请求, 获得 P- CSCF和 /或 SBC的域名 ,然后该 IMS终端执行 DNS查询,获得 P-CSCF 和 /或 SBC的 IP地址。 该 IMS终端根据该 IP地址与该 P- CSCF和 /或 SBC 建立通信连接。
该方法的不足之处同样是依赖于符合特定要求的 IP - CAN。 如果 IMS 终端当前所接入的 I P- CAN不能提供上述特定功能, 则 IMS终端无法通过 IP - CAN的初始化配置而获得 IMS网络的本地化入口服务。
方法三、 在 IMS终端中预先保存初始化配置数据, 该初始化配置数据 包括 P- CSCF和 /或 SBC的域名和 /或 IP地址。 该 IMS终端根据该域名和 / 或 IP地址与该 P-CSCF和 /或 SBC建立通信连接。
该方法的不足之处在于: 必须事先获知 IMS终端的使用地区, 以便预 先在 IMS终端中保存本地的 IMS入口配置数据。 若 IMS终端当前的实际使 用地点不同于预先设定的地区, 则该 IMS终端无法得到 IMS网络的本地化 入口服务。 发明内容

进一步地, 所述步骤 3可具体包括以下步骤: 在步骤 31 中, 所述家 庭网关向所述 IMS终端配置服务器提交 HTTP配置页面请求消息, 用于请 求业务参数配置 WEB页面; 然后在步骤 32中, 所述家庭网关收到所述 IMS 终端配置服务器返回的业务参数配置 WEB页面后, 通过电视机将所述业务 参数配置 WEB页面输出给用户, 用于用户通过遥控器选择用户所在的地理 位置信息以及配置其它业务参数; 继而在步骤 33 中, 所述家庭网关向所 述 IMS终端配置服务器提交 HTTP配置请求消息, 所述 HTTP配置请求消息 包括用户选择的地理位置信息以及用户配置的其它业务参数; 最后在步骤 34中, 所述家庭网关接收所述 IMS终端配置服务器返回的 IMS配置响应, 所述 IMS配置响应中包括 IMS本地化入口点的 IP地址, 以及配置成功的 其它业务参数; 然后将所述 IMS本地化入口点的 IP地址以及所述配置成 功的其它业务参数保存在所述家庭网关的存储模块中。

在本实施例中,所述基于 I P多媒体子系统的家庭网关将家庭内网和外 网进行隔离, 并对家庭内部的家电设备进行统一的管理。 家庭内部的所有家 电设备都可以通过所述基于 IP多媒体子系统的家庭网关与外界进行信息交 互。 对于家庭内部的所有信息家电, 所述基于 IP多媒体子系统的家庭网关 是主控计算机, 家庭内部的所有信息家电都是所述基于 I P多媒体子系统的 家庭网关的计算机外部设备。 因此, 家庭内部的设备与所述基于 IP多媒体 . 子系统的家庭网关的主处理板间的通信最终都转换为基于 USB的通信, 这样 便于内部联网设备的统一通信及管理,也起到了家庭内网和外网隔离的作用。 所有需与主机设备通信的信息家电在其以太网帧中仅封装 USB总线帧。 对于 所有信息家电, 家电发出的以太网帧只需要发送给所述基于 IP多媒体子系 统的家庭网关的主处理板。 所有信息家电都不支持 IP协议, 这些信息家电 发出的以太网帧也无法发送到外部通信网, 从而实现了家庭内网和外网隔离 的信息隔离。
参见图 2所示的本发明具体实施例一的另一示意图, 所述 IMS终端配置 服务器包括: 通信模块, 与 IP连通接入网 UP - CAN )连接, 用于经由所述 IP连通接入网对 IMS终端进行双向认证和加密通信; 数据库模块, 所述数据 库模块保存有 IMS入口点的相关信息, 所述 IMS入口点的相关信息包括 IMS 入口点的 IP地址和 /或地理位置信息; 处理模块, 分别与所述通信模块和所 述数据库模块连接, 用于: 接收所述通信模块发送的请求消息, 查询所述数 据库模块得到所述 IMS入口点的相关信息, 并发送给所述通信模块。 进一步 地, 所述通信模块可包括 HTTP服务器端子模块, 与所述 IP连通接入网连接, 所述 HTTP服务器端子模块用于: 接收所述 IMS终端发送的超文件传输协议 ( HyperText Transfer Protocol , 简称 HTTP )请求消息并进行解析, 以及 向所述 IMS终端发送携带有所述 IMS入口点的相关信息的 HTTP回应消息。 HTTP是互联网上应用最为广泛的一种网络传输协议, 用于传输超文本标记语 言 ( Hyper Text Markup Language, 简称 HTML )写的文件, 也就是我们通常 说的网页。 所述通信模块也可包括摘要认证子模块, 与所述 HTTP服务器端子 模块连接, 用于: 使用 HTTP摘要认证机制与 IMS终端进行双向认证并生成通 信密钥。 "摘要,, 式认证( Diges t authent icat ion )是一个简单的认证机 制, 最初是为 HTTP协议开发的, 因而也常叫做 HTTP摘要认证, 在 RFC2671 中描述。 该机制采用杂凑式(hash )加密方法, 以避免用明文传输用户的口 令。 摘要认证机制就是要核实: 参与通信的双方都知道双方共享的一个口令。 当服务器想要查证用户的身份, 它产生一个摘要盘问 (diges t chal lenge ) , 并发送给用户。 摘要盘问中包括了一组参数, 用户使用这些参数来产生正确 的摘要回答, 并发送给服务器。 当服务器接收到摘要响应, 也要重新计算响 应中各参数的值, 并利用客户端提供的参数值, 和服务器上存储的口令进行 比对。 如果计算结果与收到的客户响应值是相同的, 则证明客户已知道口令, 因而客户的身份验证通过。 参见 RFC 2543, 在摘要响应的状态消息中包含有 401/407 ( Unauthent icat ion )状态的时候, 表示需要进行授权检查, 在摘要 响应头部包含有一个或者多个的由密钥计算方法和密钥参数组成的域, 如表 示采用密钥检验的算法的域,以及表示主叫 /注册服务器共享密码的主叫和被 叫方所使用的授权值域(就是所有的用户在这个区域内采用相同的密码, 相 当于公钥) 。 所述通信模块还可包括加密子模块, 与所述摘要认证子模块连 接, 用于: 根据所述摘要认证子模块生成的所述通信密钥, 将发送给所述 IMS 终端的消息进行加密及对所述 IMS终端发送的消息进行解密。 更进一步地, 所述处理模块可包括查询子模块和计算子模块; 所述查询子模块与所述数据 库模块连接, 用于根据所述通信模块发送的请求查询所述数据库模块, 以获 得所述 IMS入口点的相关信息; 所述计算子模块与所述查询子模块连接, 用 于对所述查询子模块获得的所述 IMS入口点的相关信息进行计算后, 将计算 结果发送给所述通信模块。所述 IMS终端配置服务器还可包括参数配置模块, 与所述数据库模块连接, 用于: 配置所述 IMS终端对应的业务参数信息, 并 将所述业务参数信息保存在所述数据库模块中。
在本具体实施例一中,所述基于 IP多媒体子系统的家庭网关 A还可包括: 电视信号处理单元, 与主处理板 B连接, 用于进行数字电视信号的解码及模 拟电视信号和数字电视信号之间的转换; 电视信号控制及选频单元, 与所述 电视信号处理单元连接, 用于接收电视信号, 并进行电视信号的控制及频道 的选择。 所述内部接口单元 D可为电力线通信调制解调单元、 以太网接口单 元和无线局域网接入点之一或任意组合, 所述电力线通信调制解调单元用于 对数据线与电力线复用的信号进行调制和解调操作; 所述以太网接口单元用 于通过以太网连接内部网络中的信息家电设备; 所述无线局域网接入点用于 提供无线方式的通信连接。 所述计算机总线信号以太网适配单元 C可为 USB 信号以太网适配单元或 PCI总线以太网适配单元; 所述 USB信号以太网适配 单元用于在 USB信号和以太网信号间进行信号转换; 所述 PCI总线以太网适 配单元用于在 PCI信号和以太网信号间进行信号进行转换。 所述内部接口单 元 D可为电力线通信调制解调单元, 用于对数据线与电力线复用的信号进行 调制和解调操作。所述基于 IP多媒体子系统的家庭网关 A还可包括 USB信号 逻辑信号适配单元, 与所述电力线通信调制解调单元和主处理板 A连接, 用 于在 USB信号和串行的逻辑信号间进行转换。所述基于 IP多媒体子系统的家 庭网关 A还可包括一个或多个用户设备接口装置, 与所述电力线通信调制解 调单元连接, 用于在电力线通信信号与 USB信号之间进行信号转换, 并提供 USB信号接口。
本实施例中, 所述电视信号处理单元和电视信号控制及选频单元再结合 主处理板对电视信号数据处理便实现了一个机顶盒的功能。 可提供多种接口 以适配多种类型的电视机。 这些接口至少包括:
1 ) S-VIDE0 口, 输出 S视频信号。 该接口通过另配的音频转接线还可 输出 AUDIO AV音频信号;
2 ) VIDEO接口, 输出复合视频信号。 该接口通过另配的音频转接线还可 输出 AUDIO AV音频信号;

进一步地, 所述电力线通信调制解调单元能够实现电力线路中数据线与 电力线复用的信号的调制和解调操作。 由于一般家庭都有遍布各个角落的电 力线路, 利用电力线传输数据, 在使用上具有极大的便捷性, 只要在房间任 何有电源插座的地方都能使用。
此外, 在家庭中, 有一些简单的只具有一些逻辑功能的电器, 在本发明 中称之为逻辑信息家电, 如电灯、 电控的水龙头等, 除此之外的信息家电, 称之为智能信息家电, 智能信息家电的功能多, 其信息交互及数据处理的比 较复杂,而逻辑信息家电只需接收一些简单的逻辑控制命令(如打开和关闭), 并反馈状态信息(如开关状态) 即可, 不需要复杂的信息交互。 因此, 本实 施例中的所述 USB信号逻辑信号适配单元将主处理板发出的 USB控制信号, 转换为串行的逻辑控制信号, 并通过 PLC调制解调单元调制后通过电力线对 家电实现控制。
