A method and apparatus for adaptive mobile station presence verification in a cellular system. Mobile station presence verification is performed only for selected requested handoffs from a first base station (B5) to a second base station (B1), where the selected requested handoffs are chosen based on a rate of mobile station presence verifications per requested handoffs from the first base station to the second base station, that is adaptively changed as handoffs occur. In an embodiment of the invention, the rate of mobile station presence verifications per requested handoffs from the first base station (B5) to the second base station (B1) is adaptively changed based on the rates of unsuccessful verifications (318) per verification attempts (312) and, the rate of unsuccessful handoffs (318) per requested handoff attempts (308), from the first base station (B5) to the second base station (B1).
