Abstract
A method is disclosed for disambiguating a reported pilot signal so as to facilitate handoff of a mobile station. When a radio access network (RAN) receives from a mobile station a handoff request carrying a parameter that ambiguously identifies at least two sectors as the potential handoff target, the RAN will send a test probe on at least one of the potential handoff target sectors and will determine, based on mobile station response to the test probe, which sector the mobile station received the test probe on and thus which sector was the intended handoff target. The RAN may then direct the mobile station to hand off to that sector if appropriate. Further, the RAN may add the identified sector into a neighbor list of a similarly situated other mobile station, to allow the other mobile station to more efficiently hand off to the same sector if appropriate.
