An overload control method for the access media gateway and an access media gateway, the media gateway limits call to its calling party user or its called party user, set the different overload levels and the priority call assured by each overload level on the access media gateway; the user of the access media gateway is the calling party or the called party and after it detects itself overload, determines the overload level; determines whether the call is the priority call assured by the overload level, if so, processing the call according to the normal procedure; otherwise rejecting the call. The present invention prevents AG system from collapse when the high traffic volume occurs, while effectively assures the continuous connection of the high priority comprising the emergence call and/or the call of the high priority port, it may reduce the dependency on MGC, prevent MGC overload, and abate the overload of AG quickly, shorten the time about the service influence.
