Abstract
Embodiments of the present invention provide an access control method, an access control system, and an access terminal. The method includes: receiving, by an access terminal, an HTTP request message transmitted by a UE where a destination IP address is an IP address of the access terminal; obtaining an actual IP address corresponding to a website domain name according to DNS resolution when the website domain name is not the IP address of the access terminal, and controlling, according to the actual IP address, the UE to access a target site corresponding to the website domain name. The technical solutions of the present invention solve the problem that a user cannot access the target site because of the cache characteristic of the user equipment.
