Abstract: PURPOSE: A method for registering COA(Care-Of-Address) and establishing a path based on DNS(Domain Name System) in mobile communicating environment is provided to enable a communication service closed to the existing Internet capacity in a multimedia data communication application and remote mobile host service application by allowing a source host to be propagated only COA of a mobile host and to use the COA in establishing a path. CONSTITUTION: An MH(Mobile Host) present an address of its own HA(Home Agent) to FA(Foreign Agent) and requests to register a COA in the HA(11). The FA transfers the COA of MH to the HA in MH, and the HA maintains the current COA(12). The HA propagates the current COA of MH to a DNS server where the MH has registered, and the DNS server stores the COA of MH(13). The COA of MH is piggyback and propagated to an SH(Source Host)(14). The SH transfers packets to the FA on a direct path(15).

Abstract translation: 目的：提供一种在移动通信环境中注册COA（转交地址）和建立基于DNS（域名系统）的路径的方法，以使通信服务能够在多媒体数据通信应用中与现有互联网容量相关， 通过允许源主机仅传播移动主机的COA并使用COA建立路径来实现远程移动主机服务应用。 规定：MH（移动主机）向FA（外地代理）提供自己的HA（归属代理）的地址，并请求在HA（11）中注册COA。 FA将MH的COA转移到MH中的HA，HA保持当前的COA（12）。 HA将MH的当前COA传播到MH注册的DNS服务器，DNS服务器存储MH的COA（13）。 MH的COA背负并且传播到SH（源主机）（14）。 SH在直接路径（15）上将数据包传输到FA。

Abstract: PURPOSE: A method and system for filtering the web are provided to offer a priority order deciding method considering interest of a user with respect to an information search and to reduce a searching space by using an estimation mechanism. CONSTITUTION: A search demanding analyzer(200) performs a function for analyzing search demanding contents for accessing contents as a searching keyword inputted from a user to a demand of the user at supplying a search result. A search document analyzer(210) performs a function for analyzing the searched document for an adjustment adapted to the demand of the user. A search document converter(220) performs a function for processing actual application contents in a document selected adapted to the demand of the user from the selected document. A filter(230) performs a function selecting documents adjacent to the demand of the user from the searched document based on analyzed search demanding information. That is, the filter(230) receives and stores search demanding information analyzed from the search demanding analyzer(200) and extracts necessary document by applying and preparing the analyzed demanding information to initial search documents transmitted from the search document analyzer(210), and transmits the documents to the search document converter(220).

Abstract translation: 目的：提供一种用于过滤网络的方法和系统，以提供考虑用户对信息搜索的兴趣的优先级顺序决定方法，并且通过使用估计机制来减少搜索空间。 规定：搜索要求分析器（200）执行用于分析搜索要求内容以访问内容的功能，作为从用户输入的搜索关键字，以供应搜索结果时用户的需求。 搜索文档分析器（210）执行用于分析搜索到的文档以适应用户需求的调整的功能。 搜索文档转换器（220）根据所选择的文档执行用于处理适合于用户需求的文档中的实际应用内容的功能。 过滤器（230）基于分析的搜索要求信息，从搜索到的文档执行与用户的需求相邻的文档的功能。 也就是说，过滤器（230）接收并存储从搜索要求分析器（200）分析的搜索要求信息，并通过将所分析的要求信息应用于所述搜索文档分析器（210）发送的初始搜索文档来提取必要的文档，并且 将文档发送到搜索文档转换器（220）。
