Description

说明书 地址上报方法及装置、 连接建立方法及装置、 通信系统
[1] 本申请要求于 2008年 9月 4日提交中国专利局、 申请号为 200810215607.6、 发明 名称为 "地址上报方法及装置、 连接建立方法及装置、 通信系统"的中国专利申请 的优先权, 其全部内容通过引用结合在本申请中。
[2] 技术领域
[3] 本发明涉及通信技术领域, 具体涉及地址上报方法及装置、 连接建立方法及装 置、 通信系统。
[4] 发明背景
[5] 目前, 数字用户线路 (DSL: Digital Subscriber
Line) 是一种宽带接入技术, 已经广泛进入千家万户。 由此带来的是范围广泛的 宽带技术应用, 例如网络电话 (VOIP: Voice over Internet
Protocol) 、 交互式网络电视 (IPTV: Internet Protocol
Television) 等, 针对这些应用或应用的组合形成各种各样的基于网际协议 (IP : Internet
Protocol) 的设备类型。 为了使用上述宽带技术应用而进入家庭的 IP应用终端可 以称为用户驻地设备 (CPE: Customer Premises
Equipment) 。 在实际应用中, 由自动配置服务器 (ACS: Auto-configuration Server) 负责对用户驻地设备进行自动配置, 以达到不需要用户对用户驻地设备 进行设置, 用户驻地设备就可以正常工作的目的。
[6] 为了完成自动配置服务器对用户驻地设备进行的自动配置, 用户驻地设备要提 供连接请求地址 (ConnectionRequestURL) 消息, 连接请求地址由用户驻地设备 自行生成, 包括用户驻地设备的 IP地址、 端口号和路径等, 如 201.12.34.56: 876 5/用户驻地设备路径 (CPE
path) 。 通过该消息可以使自动配置服务器能够主动与用户驻地设备进行通信, 具体地, 如果自动配置服务器需要与用户驻地设备建立连接, 可以根据连接请 求地址中的地址, 使用超文本传输协议 (HTTP: Hyper Text Transfer Protocol) 向用户驻地设备发出 HTTP
Get请求, 用户驻地设备收到该请求并验证自动配置服务器的合法性后, 将发起 与自动配置服务器的连接。
[7] 为了实现上述流程, 自动配置服务器必须保存用户驻地设备发送的连接请求地 址, 以便可以随吋向用户驻地设备发送请求。 在实际应用中, 用户驻地设备可 以维持连接请求地址所使用的端口和路径基本不变, 但是对于 IP地址, 在数字用 户线路网络中, 用户驻地设备所获得的广域网 (WAN: Wide Area
Network) 侧 IP地址很有可能是由宽带运营商动态分配的, 导致每次拨号获得的 I P地址都不一样, 因此为了实现自动配置服务器可以随吋向用户驻地设备发送请 求, 要求自动配置服务器必须保存用户驻地设备的最新的连接请求地址。 于是 用户驻地设备必须在每次与自动配置服务器进行通信吋都携带连接请求地址, 以便自动配置服务器每次检査并更新用户驻地设备最新的连接请求地址。
[8] 从上述现有技术的方案可以看出: 由于用户驻地设备必须在每次与自动配置服 务器进行通信吋都携带连接请求地址, 增加了用户驻地设备的处理负荷, 降低 了用户驻地设备的处理效率。
[9] 发明内容
[10] 本发明实施例提供了一种地址上报方法及装置、 连接建立方法及装置、 通信系 统, 使用本发明实施例所提供的技术方案, 可以使得用户驻地设备不需要在每 次与自动配置服务器进行通信吋都携带连接请求地址, 减少了用户驻地设备的 处理负荷, 提高了用户驻地设备的处理效率。
[11] 本发明实施例提供了一种地址上报方法, 包括:
[12] 获取网络地址和静态信息;
[13] 向动态域名系统服务器注册所述网络地址和所述静态信息;
[14] 构造包括所述静态信息的第一连接请求地址;
[15] 将所述第一连接请求地址上报给自动配置服务器。
[16] 本发明实施例还提供了一种连接建立方法, 包括:
[17] 向动态域名系统服务器发送地址査询消息, 所述地址査询消息包括用户驻地设 备的静态信息; [18] 接收来自所述动态域名系统服务器的地址响应消息, 所述地址响应消息包括与 所述静态信息对应的网络地址;
[19] 根据所述网络地址向所述用户驻地设备发送连接建立消息。
[20] 本发明实施例还提供了一种地址上报装置, 包括:
[21] 获取单元, 用于获取网络地址和静态信息;
[22] 注册单元, 用于向动态域名系统服务器注册所述获取单元获取的所述网络地址 和静态信息;
[23] 构造单元, 用于构造包括所述静态信息的连接请求地址;
[24] 上报单元, 用于上报所述构造单元构造的所述连接请求地址。
[25] 本发明实施例还提供了一种连接建立装置, 包括:
[26] 地址査询消息发送单元, 用于发送地址査询消息, 所述地址査询消息包括用户 驻地设备的静态信息;
[27] 接收单元, 用于接收地址响应消息, 所述地址响应消息包括与所述静态信息对 应的网络地址;
[28] 连接建立消息发送单元, 用于根据所述接收单元接收的所述网络地址发送连接 建立消息。
[29] 本发明实施例还提供了一种通信系统, 包括:
[30] 用户驻地设备, 用于获取网络地址和静态信息; 向动态域名系统服务器注册所 述网络地址和静态信息; 构造包括所述静态信息的连接请求地址; 上报所述连 接请求地址; 接收连接建立消息;
[31] 自动配置服务器, 用于发送地址査询消息, 所述地址査询消息包括用户驻地设 备的所述静态信息; 接收地址响应消息, 所述地址响应消息包括与所述静态信 息对应的网络地址; 根据所述网络地址发送连接建立消息;
[32] 动态域名系统服务器, 用于注册所述网络地址和静态信息; 接收所述地址査询 消息, 发送所述地址响应消息。
[33] 从上述本发明实施例所提供的技术方案可以看出, 由于本发明实施例的技术方 案中向自动配置服务器发送包括静态信息的连接请求地址, 并且自动配置服务 器可以通过静态信息向动态域名系统 (DDNS: Dynamic Domain Name System) 服务器获取与静态信息对应的网络地址, 进而通过网络地址与用户驻地 设备建立连接, 所以即使用户驻地设备的网络地址经常变化, 但是由于静态信 息没有变, 所以用户驻地设备不需要在每次与自动配置服务器进行通信吋携带 连接请求地址, 从而可以降低用户驻地设备的处理负荷, 进而提高用户驻地设 备的处理效率。
[34] 附图简要说明
[35] 为了更清楚地说明本发明实施例或现有技术中的技术方案, 下面将对实施例或 现有技术描述中所需要使用的附图作简单地介绍, 显而易见地, 下面描述中的 附图仅仅是本发明的一些实施例, 对于本领域普通技术人员来讲, 在不付出创 造性劳动性的前提下, 还可以根据这些附图获得其他的附图。
[36] 图 1为本发明实施例中地址上报方法实施例的流程图;
[37] 图 2为本发明实施例中连接建立方法实施例一的流程图;
[38] 图 3为本发明实施例中连接建立方法实施例二的流程图;

[41] 图 6为本发明实施例中通信系统实施例的结构图。
[42] 实施本发明的方式
[43] 下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案进行清楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是全部 的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有作出创造性劳 动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
[44] 先介绍本发明实施例提供的地址上报方法, 地址上报方法描述的是用户驻地设 备的处理流程, 图 1描述了地址上报方法实施例一的流程, 包括:
[45] 101、 获取网络地址和静态信息;
[46] 该网络地址是用户驻地设备通过拨号或其他方式从网络侧获得的, 一般为 IP地 址; 静态信息是用户驻地设备的标识信息, 一般情况下不会改变, 例如静态信 息可以是用户驻地设备向 DDNS服务器注册的域名;
[47] 102、 向 DDNS服务器注册网络地址和静态信息; [48] 具体地, 可以向 DDNS服务器发送了更新消息注册网络地址和静态信息; 如果 DDNS服务器没有保存与该静态信息对应的网络地址, 则直接建立该网络地址与 该静态信息的对应关系; 如果 DDNS服务器已经保存了该静态信息与另一网络地 址的对应关系, 则在收到该更新消息后, 将该另一网络地址替换为该网络地址 , 从而知道静态信息就可以从 DDNS服务器获得对应的网络地址;
[49] 103、 构造包括静态信息的第一连接请求地址;
[50] 其中, 构造第一连接请求地址的过程可以是: 将原来包括网络地址的连接请求 地址中的网络地址替换为静态信息获得第一连接请求地址; 也可以是重新构建 包括静态信息的第一连接请求地址;
[51] 104、 将第一连接请求地址上报给自动配置服务器。
[52] 向自动配置服务器上报第一连接请求地址后, 就可以让自动配置服务器获知用 户驻地设备的静态信息, 进而可以通过 DDNS服务器获知用户驻地设备的网络地 址, 从而可以随吋与用户驻地设备通信。
[53] 从以上方法实施例可以看出, 由于向自动配置服务器发送包括静态信息的连接 请求地址, 所以即使用户驻地设备的网络地址经常变化, 但是由于静态信息没 有变, 所以用户驻地设备不需要在每次与自动配置服务器进行通信吋携带连接 请求地址, 从而可以降低用户驻地设备的处理负荷, 进而提高用户驻地设备的 处理效率。
[54] 具体地, 用户驻地设备可以在从未向自动配置服务器发送过连接请求地址吋, 向自动配置服务器发送连接请求地址。
[55] 由于用户驻地设备每次从网络侧获得的网络地址可能都不一样, 因此为了保证
DDNS维护的用户驻地设备的静态信息与网络地址的对应关系的准确性, 如果用 户驻地设备获取了不同的新网络地址, 本发明实施例提供的网络地址上报方法 还可以包括:
[56] 向 DDNS服务器注册新网络地址和静态信息; 在该过程中, DDNS服务器会使 用新网络地址替换原有的网络地址, 从而确保维护的静态信息与网络地址的对 应关系的准确性。
[57] 在连接请求地址为第一连接请求地址吋, 由于连接请求地址除了包括静态信息 外还包括端口号和路径信息, 此吋如果连接请求地址的端口号、 和 /或路径信息 、 和 /或静态信息发生了变化, 都需要重新发送连接请求地址给自动配置服务器 , 从而将改变后的端口号、 和 /或改变后的路径信息、 和 /或静态信息发送给自动 配置服务器, 确保自动配置服务器能够保存正确的连接请求地址, 因此如果端 口号发生改变, 本发明实施例提供的网络地址上报方法还可以包括:
[58] 构造第二连接请求地址, 第二连接请求地址包括静态信息和改变后的端口号;
[59] 向自动配置服务器上报第二连接请求地址。
[60] 如果路径信息发生改变, 本发明实施例提供的网络地址上报方法还可以包括:
[61] 构造第三连接请求地址, 第三连接请求地址包括静态信息和改变后的路径信息
[62] 向自动配置服务器上报第三连接请求地址。
[63] 如果路径信息和端口号都发生改变, 本发明实施例提供的网络地址上报方法还 可以包括:
[64] 构造第三连接请求地址, 第三连接请求地址包括静态信息、 改变后的路径信息 和改变后的端口号;
[65] 向自动配置服务器上报第三连接请求地址。

[83] 302、 用户驻地设备向自动配置服务器上报连接请求地址; [84] 用户驻地设备上报的给自动配置服务器的连接请求地址的地址部分使用的 301 中的用户驻地设备的静态信息, 具体地, 用户驻地设备可以在下列情况向自动 配置服务器上报连接请求地址:
[85] 用户驻地设备以前从未向该自动配置服务器上报过连接请求地址; 或
[86] 用户驻地设备的连接请求地址发生了变化; 或
[87] 用户驻地设备上保持的自动配置服务器地址发生了变化; 或
[88] 自动配置服务器向用户驻地设备査询连接请求地址。
[89] 303、 自动配置服务器向 DDNS服务器査询用户驻地设备的静态信息对应的网络 地址;
[90] 自动配置服务器在需要给用户驻地设备发送连接建立请求吋, 向 DDNS服务器 査询用户驻地设备上报中的连接请求地址中静态信息对应的网络地址;
[91] 304、 自动配置服务器向用户驻地设备发送连接建立消息发起连接。
[92] 自动配置服务器根据用户驻地设备提供的连接请求地址和 303中获得的用户驻 地设备的网络地址向用户驻地设备发起连接。
[93] 从上可知, 本实施例中用户驻地设备向自动配置服务器发送包括静态信息的连 接请求地址, 自动配置服务器可以通过静态信息向 DDNS服务器获取与静态信息 对应的网络地址, 进而通过网络地址与用户驻地设备建立连接, 所以即使用户 驻地设备的网络地址经常变化, 但是由于静态信息没有变, 所以用户驻地设备 不需要在每次与自动配置服务器进行通信吋携带连接请求地址, 从而可以降低 用户驻地设备的处理负荷, 可以提高用户驻地设备的处理效率。
[94] 再介绍本发明实施例提供的地址上报装置, 图 4描述了地址上报装置实施例的 结构, 包括:
