Example Embodiment

[0055] The present invention will be further described in detail below in conjunction with the drawings and embodiments:

[0056] First, briefly introduce several related protocols used in the present invention:

[0057] TCP (Transmission Control Protocol) uses a three-way handshake mechanism to establish a connection. The first packet of the handshake is a SYN packet, and the second packet is a SYN / ACK packet, indicating that it responds to the first SYN packet while continuing the handshake process. The third packet is just a response, expressed as an ACK packet. .

[0058] HTTP (Hypertext Transfer Protocol) is a common, object-oriented protocol that uses the 80 end of TCP to support WWW (World Wide Web) browsing: the browser sends a request to the server, and the server responds to the corresponding web page. The client can send many different types of information to the server, for example: GET means requesting a WEB page; HEAD means asking the server to send header informatio...

Abstract

The invention provides a forced portal realizing method, including the steps: a user builds a connection with a web server to be accessed through wideband access server (BAS); then, the user sends HTTP or HTTPS request message; the BAS receives the message and then configures web page containing forced portal information and sends the web page to the user; the user receives the web page and then automatically connect to forced portal website. The invention can make BAS easily realize forced portal and can appoint concrete web page of forced portal and can carry parameters to web server, flexibly setting if it displays parameters in address column and can make BAS flexibly control the mode of user accessing web page by HTML and network programming technique.

Description

technical field [0001] The present invention relates to a forced portal (PORTAL) pushing technology, in particular to a mandatory PORTAL implementation method, in particular to a mandatory PORTAL implementation method based on HTML language (hypertext markup language). Background technique [0002] The demand for information in modern society is increasing. The application of broadband technology provides us with a broad application platform and builds a real information highway for us. In broadband access services, operators often set up dedicated WWW servers on the Internet for the convenience of users or other business purposes, and the WWW servers that provide directory services are called PORTAL servers. The corresponding Web pages are called PORTAL pages, which mainly provide users with service catalogs. Users only need to click on the corresponding links to enter the required service pages and obtain the required information or other content. Mandatory PORTAL is a va...
