When an unauthenticated user goes online, the device forces the user to log in to a specific site, where the user can access services for free. When users need to use other information on the Internet, they must be authenticated on the portal website. Only after passing the authentication can they use Internet resources.
Users can actively access a known Portal authentication website and enter their username and password for authentication. This method of starting Portal authentication is called active authentication. On the contrary, if the user attempts to access other external networks through HTTP, he will be forced to visit the Portal authentication website to start the Portal authentication process. This method is called forced authentication.
Portal services can provide operators with convenient management functions. Portal websites can carry out advertising, community services, personalized services, etc., allowing broadband operators, equipment providers and content service providers to form an industrial ecosystem.
