Abstract: A device receives a default cell handoff parameter set from a base station within a cellular network. The device receives a modified handoff parameter set, wherein the modified handoff parameter set is different than the default cell handoff parameter set, and tests a mobile device in different geographic locations served by the base station, using the modified handoff parameter set, to measure one or more network/call service parameters associated with handoff of the mobile device to a neighboring cell. The device identifies optimum modified handoff parameters for the mobile device based on the measured one or more network/call service parameters.
