The invention discloses a method, apparatus and system for WLAN personalized reminding. The method comprises the following steps: when a user terminal accesses a core network through a WLAN, a wireless access gateway transmits WLAN user access information to a WLAN operation platform through the core network; when a core network gateway receives an HTTP request sent by the user terminal, the core network gateway forwards the HTTP request to the WLAN operation platform; and the WLAN operation platform pushes reminding information to the user terminal based on the WLAN user access information when receiving the HTTP request. By adoption of the method, apparatus and system disclosed by the invention, a function of transmitting the WLAN access network circuit information to the core network is realized, therefore personalized reminding pages can be pushed to users in real time, thereby enhancing the use perception of the users after switching from LTE to the WLAN in an L+W network.
