Abstract
A method and system for providing an adaptive IP handoff triggering system for a wireless communication system that consists of either the same or heterogeneous wireless access technologies. A mobile node is notified of at least one pre-trigger timing parameter by a current access network. At least one variable handoff threshold is constructed with the mobile node based on the at least one pre-trigger timing parameter. An IP handoff is then initiated to a candidate access network when pilot beacon signal strength of the mobile node reaches the variable handoff threshold.
