The invention discloses a method to realize the tunnel control of a base station and a Wimax assess gateway media plane. The method adds media plane error report transmission between the base stationand the Wimax access gateway, which comprises: the data base or the Wimax access gateway receives a user data message sent by the target end, and judges whether a media plane tunnel that is corresponding to the user data message exists according to the media plane tunnel key information. If yes, the normal data operation is executed; if no, the media plane error report is sent back to the sendingend, and the media plane tunnel is released. The invention accomplishes the release of an invalid media plane tunnel between the base and the Wimax access gateway through the media plane error reportand the correspondingly processing mechanism at the base station and the Wimax access gateway, so as to avoid the negative effects of the invalid media plane tunnel on the system capability and performance.
