The present invention relates to a method, a system, a gateway, and a server for canceling redirection. When balances of a user are insufficient, a gateway (GW) receives a redirection policy delivered by a policy and charging rules function (PCRF) and redirects the user to a recharging page of a server; after recharging is finished, the server sends a recharging success packet to the GW, and the GW instructs the PCRF to cancel the redirection policy. In this way, after the recharging succeeds, the server directly sends the recharging success packet to the GW, and the GW can immediately instruct the PCRF to cancel the redirection policy after receiving the packet. Therefore, no delay problem of a billing system exists, thereby avoiding that the user is repeatedly redirected to the recharging page of the server during a delay time and enhancing user experience.
