Abstract
In the method of emergency service call back in a wireless system, an emergency intersystem page is sent from a first system to a second system such that the emergency intersystem page is identifiable as requesting paging of a mobile station for an emergency call back. The second system receives the mobile station identifier (MSID) and mobile equipment identity (MEID) of the paged mobile station from the first system in or with the emergency intersystem page, and uses the MSID to page the mobile station. The second system verifies the page response is from the paged mobile station using the MEID received from the responding mobile station and the MEID received in association with the emergency intersystem page. The emergency call back can then be completed when the mobile station is verified.
