Abstract
A method for inter-RAT idle handoff is provided by transmitting a handoff initiation signal from a cell associated with a carrier for a first Radio Access Technology (RAT) area, the cell being located in an overlap coverage area with a second RAT area and adjacent to the second RAT area. Spatial hysteresis is provided by the new triggering method to eliminate the ping-pong issue when a mobile move along the border area. The invention also reduces network resource consumption due to ping-ponging.
