Abstract

A wireless network detects when all the pilots in an Active Set for an access terminal (AT) are border cells. The network then sends a new PilotDrop threshold to the AT, and detects when the AT subsequently sends a RouteUpdate message indicating that any of the Pilots in the Active Set have fallen below the new PilotDrop threshold. The network may then send signals to the AT to trigger a handoff to the underlying carrier. The handoff may be a hard handoff, or effect a personality change of the AT.
