Abstract
The present invention provides a method of determining handoff parameters. One embodiment of the method includes determining values of a hysteresis for a handoff from a serving cell, one or more pairwise offset values for hand off between the serving cell and one or more neighbor cells, and one or more times-to-trigger (TTTs) for hand off between the serving cell and the neighbor cell(s). The values may be determined So that hand off is triggered beyond a first distance from the serving cell selected to avoid ping-ponging and within a second distance from the serving cell selected so that a mobile unit moving at a selected velocity does not travel beyond a third distance within the TTT.
