A method is provided for paging a mobile station (40) served by a wireless telecommunications network (A). The method includes: remembering a last known location of the mobile station (40), and implementing a first paging strategy for the mobile station (40) within a first collection of cells (32) served by a first mobile switching center (20). If a response to the first paging strategy is not received by the first mobile switching center (20), then the method further includes: selecting one or more cells (32) served by a second mobile switching center (22) based upon the last known location of the mobile station (40); identifying the selected cells (32) in an intersystem paging request; forwarding the intersystem paging request from the first mobile switching center (20) to the second mobile switching center (22); and, in response to the second mobile switching center (22) receiving the intersystem paging request, paging the mobile station (40) in those cells (32) served by the second mobile switching center (22) which are identified in the intersystem paging request.
