The embodiment of the invention provides a method and a device for optimizing paging of a mobile station (MS). When the MS is in the paging listening interval, the position of a paging message of the MS in the paging listening interval is firstly obtained according to the paging rules of the MS; and then the MS can receive one or more frames on the position according to the obtained position. Therefore, the MS does not need to receive all the frames in the paging listening interval and can receive the corresponding paging message only by receiving one or more frames, thereby reducing the listening burden of the MS, saving the equipment resources of the MS and further improving the running performance of the whole system.
