In the application.
技术领域 Technical field
本发明涉及一种网络技术领域， 尤其涉及一种网页推送方法、 ***及其装 置。  The present invention relates to the field of network technologies, and in particular, to a webpage pushing method, system, and device thereof.
背景技术 Background technique
在互联网应用中， 为了宣传和提供一些链接，接入服务商会在用户接入网 络第一次访问某页面时，通过网页推送技术强制为用户推送一个不相关的网页 作为强制门户。 比如当用户通过 DSL线路使用 PPPoE拨号上网时， 第一次访问 www. sohu.com网页， 局端设备 B AS ( Broadband Access Server, 宽带接入服务 器）在自动识别用户是首次登陆访问 internet网络后，局端设备会为用户推送一 个新的页面以替换 www. sohu.com网页。  In the Internet application, in order to promote and provide some links, the access service provider will force the user to push an irrelevant webpage as a mandatory portal through the webpage push technology when the user accesses the network for the first time. For example, when a user uses PPPoE dial-up Internet access through a DSL line, the first time visits the www.sohu.com webpage, and the central office equipment B AS (Broadband Access Server, Broadband Access Server) automatically recognizes that the user is the first to access the internet network. The central office device will push a new page for the user to replace the www.sohu.com web page.
请参阅图 1 , 一种现有的网页推送方法是以 BAS作为强制门户的关键控制 点， DSL用户通过 PPPoE ( Point-to-Point Protocol Over Ethernet, 基于以太网的 点到点协议）拨号上网时，由 BAS参与或搭建专门的服务器来处理报文的检测、 伪装转换， 比如 BAS直接代替 WEB server2与 PC交互， BAS负责 HTTP重定向报 文等。 然而， 由 BAS参与处理报文的检测、 伪装转换， 会大大增加 BAS的处理 负荷； 如果釆用专门的服务器来处理强制门户网页的转换工作， 又会增加组网 复杂性； 此外， BAS作为强制门户网页的控制者， 与单个 PC机的终端用户属 于不同的层面， 其配合强制门户功能下发的参数， 无法做到或者不便于做到适 应各个终端个性化差异。  Referring to FIG. 1 , an existing web page push method is a key control point of the BAS as a mandatory portal. When a DSL user dials up through a Point-to-Point Protocol Over Ethernet (PPoE) The BAS participates in or builds a dedicated server to handle packet detection and masquerading conversion. For example, BAS directly replaces WEB server2 to interact with the PC, and BAS is responsible for HTTP redirection packets. However, the detection and masquerading of messages processed by BAS will greatly increase the processing load of BAS. If a dedicated server is used to handle the conversion of mandatory portal pages, the complexity of networking will increase. In addition, BAS is mandatory. The controller of the portal webpage belongs to a different level from the end user of a single PC. The parameters that are issued by the mandatory portal function cannot be implemented or adapted to the individualized differences of the individual terminals.
随着 DSL技术的发展， 宽带接入被广泛商用， 宽带接入终端设备， 也由早 期的简单物理层信号转换的设备， 演变为家庭网关类设备。基于对家庭网关类 终端设备的管理， 目前业界流行宽带终端管理协议 （ CWMP , CPE WAN Management Protocol ) , 其基于 TR-069协议族来构建对终端的网络管理功能。 另一种现有的网页推送方法是基于 TR-069远程管理控制的强制门户功能，其主 要通过 TR-069远程控制，可以配置强制门户的网页地址，从一定程度上借助现 成的终端管理体系来开展强制门户业务。然而，通过 TR-069远程管理***来实 现配置强制门户网页，不便于单个用户的个性化配置操作，也不利于业务拓展。 发明内容 With the development of DSL technology, broadband access has been widely used, and broadband access terminal equipment has also evolved from a simple physical layer signal conversion device to a home gateway device. Based on the management of the home gateway type terminal device, the current popular broadband terminal management protocol (CWMP, CPE WAN Management Protocol) is based on the TR-069 protocol family to construct a network management function for the terminal. Another existing webpage push method is a mandatory portal function based on the TR-069 remote management control, which is mainly configured by the TR-069 remote control, and can configure the webpage address of the mandatory portal, to a certain extent The terminal management system is used to carry out the mandatory portal business. However, configuring the mandatory portal webpage through the TR-069 remote management system is not convenient for individual user configuration operations, and is not conducive to business development.

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。  BRIEF DESCRIPTION OF THE DRAWINGS The technical solutions in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative work are within the scope of the present invention.
本发明网页推送方法是将强制门户的控制点下移到用户终端接入类设备， 如家庭网关设备上， 当用户通过终端接入设备链接网络时， 用户接入终端检测 到用户发起的 HTTP访问， 终端修改或构造 HTTP报文， 控制 HTTP访问转移到 强制门户。  The webpage pushing method of the present invention moves the control point of the mandatory portal to the user terminal access type device, such as the home gateway device. When the user connects to the network through the terminal access device, the user access terminal detects the HTTP access initiated by the user. The terminal modifies or constructs an HTTP message, and controls the transfer of HTTP access to the mandatory portal.
目前在网页推送的技术上，主要有基于 HTTP重定向和地址转换两种方法。 请参阅图 2 , 本发明网页推送方法基于 HTTP重定向方法的实施例包括以下步 骤：  At present, there are two methods based on HTTP redirection and address translation in the technology of web page push. Referring to FIG. 2, an embodiment of the webpage pushing method of the present invention based on the HTTP redirection method includes the following steps:
首先， PC发起访问 WEB server2,完成 TCP的三次握手交互，即 PC发送 TCP First, the PC initiates access to the WEB server2, completing the three-way handshake interaction of the TCP, that is, the PC sends the TCP.
SYN报文， WEB server2返回 TCP SYN ACK报文， PC收到 SYN ACK后， 发送 TCP ACK报文； The SYN packet, the WEB server2 returns a TCP SYN ACK packet, and after receiving the SYN ACK, the PC sends a TCP ACK packet.
其次， PC机发送 HTTP才艮文， 如 src=PC, dst=web server2;  Second, the PC sends an HTTP message, such as src=PC, dst=web server2;
再次， 用户接入终端 HGW ( Home Gate Way , 家庭网关）检测到此报文后， 构造 HTTP重定向报文给 PC, 并可选地在构造或者修改的 HTTP报文内容中， 增加用于标识自身设备或者用户侧设备， 或者与用户相关的特性化信息字段， 即构造报文的 src地址 =web server2, dst地址 =PC, location填写强制门户服务器 地址， 可选地携带 HGW特性化信息字段， 其中， location标识重定向的目的地 址， 所携带的 HGW特性化信息字段用于提供强制门户服务器做后续判断。 可 以理解， 上述 HGW特性化信息字段可以是 HGW的 OUI序列号， 可以是用户上 网帐号， 当前线路速率， 也可以是用户随意选定的一个特征字符， 比如兴趣选 择等； After the user access terminal HGW (Home Gate Way, the home gateway) detects the packet, it constructs an HTTP redirect message to the PC, and optionally adds the identifier for the HTTP packet content in the constructed or modified HTTP packet. The self-device or user-side device, or the characterization information field associated with the user, that is, the src address of the constructed message = web server2, dst address = PC, location fills the mandatory portal server address, optionally carries the HGW characterization information field, The location identifier is redirected to the destination address, and the HGW characterization information field is used to provide a mandatory portal server for subsequent determination. Can It is understood that the HGW characterization information field may be an OUI serial number of the HGW, and may be a user online account, a current line rate, or a feature character randomly selected by the user, such as an interest selection;
再次， PC机的 IE浏览器接收到重定向报文后， 发起到强制门户服务器的 访问；  Again, after receiving the redirect message, the IE browser of the PC initiates access to the mandatory portal server;
再次， 强制门户服务器解析报文头部的参数， 可以向运营商运营支撑*** ( Operating Support System, OSS )查询相关信息， 或者根据服务器自身的门 户推送规则， 适配一个网页， 响应给 PC用户；  Again, forcing the portal server to parse the parameters of the packet header may query the operator's Operation Support System (OSS) for related information, or adapt a web page according to the server's own portal push rules, and respond to the PC user;
再次， PC用户与适配的网页进行后续交互。  Again, the PC user performs subsequent interactions with the adapted web page.
在上述步骤中， 关于重定向部分的内容补充举例说明如下：  In the above steps, the supplementary content about the redirection part is as follows:
比如， 欲使浏览器重定向到 IP地址 172.19丄 224 , 所携带的参数为 hgw_oui=00A23C002A000123 和 linerate=2M, 这里 hgw— oui表示用户使用的 HGW的 oui序列号为 00A23C002A000123 , linerate表示线路下行速率为 2M左 右， 报文的关键内容为：  For example, if the browser is to be redirected to the IP address 172.19丄224, the parameters carried are hgw_oui=00A23C002A000123 and linerate=2M, where hgw_oui indicates that the oui sequence number of the HGW used by the user is 00A23C002A000123, and linerate indicates that the line downlink rate is Around 2M, the key content of the message is:
HTTP/1.1 302  HTTP/1.1 302
Location: http:〃172.19.1.224/?hgw— oui=00A23C002A000123&linereate=2M 强制门户服务器拿到此报文后， 如果其中携带有 HGW特性化信息字段， 解析出携带的特性化信息字段： hgw— oui, linerate, 可以向运营商 OSS***查 询 hgw— oui所对应的注册用户信息， 比如家庭地址， 所在片区， 个人喜好等， 然后强制门户服务器根据实施策略， 结合家庭地址、 片区、 喜好、 线路速率， 决定将这个访问指定到哪个网页上， 然后将对应网页返回给 PC用户。  Location: http:〃172.19.1.224/?hgw— oui=00A23C002A000123&linereate=2M After the port server receives the message, if it carries the HGW characterization information field, parse out the characterization information field that is carried: hgw—oui, Linerate, can query the operator OSS system for the registered user information corresponding to hgw-oui, such as home address, location, personal preference, etc., and then force the portal server to determine the home address, region, preference, and line rate according to the implementation policy. Specify which page to access this visit to, and then return the corresponding web page to the PC user.
请一并参阅图 3 , 本发明网页推送方法基于地址转换的强制门户方法包括 以下步骤：  Referring to FIG. 3 together, the method for forcing a webpage based on address translation according to the present invention includes the following steps:
首先， PC发起访问 WEB server2,完成 TCP的三次握手交互，即 PC发送 TCP SYN报文， WEB server2返回 TCP SYN ACK报文， PC收到 SYN ACK后， 发送 TCP ACK报文；  First, the PC initiates access to the WEB server2, and completes the three-way handshake interaction of the TCP, that is, the PC sends a TCP SYN packet, and the WEB server2 returns a TCP SYN ACK packet. After receiving the SYN ACK, the PC sends a TCP ACK packet.
其次， PC机发送 HTTP才艮文， 如 src=PC, dst=web server2;  Second, the PC sends an HTTP message, such as src=PC, dst=web server2;
再次， HGW检测到此报文后， 修改报文相关字段， 将报文发给强制门户， 其中可选地在构造或者修改的 HTTP报文内容中， 增加用于标识自身设备或者 用户侧设备， 或者与用户相关的特性化信息字段， 即构造报文的 src地址 =PC, dst地址 =强制门户服务器， 修改访问的网页地址，可选地增加 HGW特性化信息 字段， 增加的 HGW特性化信息字段用于提供强制门户服务器做后续判断。 可 以理解， 上述 HGW特性化信息字段可以是 HGW的 OUI序列号， 可以是用户上 网帐号， 当前线路速率， 也可以是用户随意选定的一个特征字符， 比如兴趣选 择等； After the HGW detects the packet, the HGW modifies the packet-related field and sends the packet to the mandatory portal. Optionally, the device adds or is used to identify the device or The user-side device, or the characterization information field associated with the user, that is, the src address of the constructed message = PC, dst address = mandatory portal server, modify the visited web page address, optionally increase the HGW characterization information field, and increase the HGW. The characterization information field is used to provide a mandatory portal server for subsequent judgment. It can be understood that the HGW characterization information field may be an OUI serial number of the HGW, and may be a user online account, a current line rate, or a feature character randomly selected by the user, such as an interest selection.
再次， 强制门户服务器解析报文头部的参数， 可以向运营商 OSS***查询 相关信息， 或者根据服务器自身的门户推送规则， 适配一个网页， 响应给 PC 用户；  Again, forcing the portal server to parse the parameters of the packet header may query the operator OSS system for related information, or adapt a web page according to the server's own portal push rule, and respond to the PC user;
再次， HGW截获到强制门户返回给 PC的响应报文， 需要修改报文的源 IP 地址为 web server2, 然后发给 PC。  The HGW intercepts the response packet sent to the PC by the mandatory portal. The source IP address of the packet needs to be modified to be web server2, and then sent to the PC.
在上述步骤中， 关于修改访问的网页地址补充举例说明如下：  In the above steps, an example of supplementing the web address of the modified access is as follows:
比如， 假定强制门户地址为 172.19.1.224, 在上述流程步骤 3中， 增加家庭 网关特性化信息字段 hgw— oui=00 A23 C002A000123 和 linerate=2M , 这里 hgw— ou表示用户使用的 HGW的 oui序列号为 00A23C002A000123 , linerate表示 线路下行速率为 2M左右， 网页地址将变为：  For example, assuming the mandatory portal address is 172.19.1.224, in the above process step 3, the home gateway characterization information fields hgw_oui=00 A23 C002A000123 and linerate=2M are added, where hgw_ou represents the oui serial number of the HGW used by the user. For 00A23C002A000123, linerate indicates that the line downlink rate is about 2M, and the web page address will become:
http :// 172.19.1.224/?hgw_oui=00A23C002A000123 &linereate=2M  Http :// 172.19.1.224/?hgw_oui=00A23C002A000123 &linereate=2M
强制门户服务器拿到此报文后， 如果其中携带有 HGW特性化信息字段， 解析出携带的特性化信息字段： hgw— oui, linerate, 可以向运营商 OSS***查 询 hgw— oui所对应的注册用户信息， 比如家庭地址， 所在片区， 个人喜好等， 然后强制门户服务器根据实施策略， 结合家庭地址、 片区、 喜好、 线路速率， 决定将这个访问指定到哪个网页上， 然后将对应网页返回给 PC用户。  After the mandatory portal server obtains the packet, if it carries the HGW characterization information field, it parses out the characterization information field: hgw—oui, linerate, and can query the operator OSS system for the registered user corresponding to hgw—oui. Information, such as home address, location, personal preference, etc., then force the portal server to decide which web page to assign the visit to, based on the implementation policy, combined with the home address, region, preferences, and line rate, and then return the corresponding web page to the PC user. .
