In 306, the first-level advertisement page is pushed when the terminal requests authentication (that is, the advertisement is pushed for the first time), and in step 311, the second-level advertisement page is pushed after the terminal passes the authentication. (that is, the second push of advertisements), realizing multi-level advertisement push. Although the advertisement page pushed in step 311 is still a Portal page, it does not require the terminal user to fill in and report authentication information such as user name and password, and only displays the advertisement page to the terminal user.

When the advertisement page is pushed corresponding to the user's ownership information, the display time of the advertisement page and other aspects can also be controlled. Examples are as follows: For example, for advanced users, advanced permissions can be supported, such as enjoying no-advertising services, that is, after the user is successfully authenticated, it is found that the user is an advanced user, then the support has a higher priority, and the advertisement page can be pushed in 311. After closing the advertisement page for a period of time, end users can still enjoy network services; for other non-advanced users, end users need to open the advertisement page all the time, and the advertisement page cannot be closed in order to enjoy network services. The heartbeat protocol between the page (that is, the advertisement page) and the terminal, if the front-end Portal fails to receive the heartbeat message from the terminal within a certain period of time, it will trigger the terminal's logout request.

In the advertisement push method of this embodiment, the advertisement page corresponding to the AP identifier is obtained through the pre-Portal according to the AP identifier carried in the HTTP request sent by the terminal, and the corresponding advertisement page is pushed according to the AP, which improves the targeting of the advertisement push. sex.
