1. A method for controlling handoffs in a wireless communication system, comprising the steps of:
- receiving a plurality of vectors associated with a mobile unit;
detecting multipath propagation when at least two of the plurality of received vectors include identical location and time coordinates;
performing a handoff when multipath propagation is detected, wherein each vector comprises three dimensional terrestrial data; and
further comprising the steps of;
calculating a magnitude of each of the plurality of received vectors;
combining the calculated magnitudes into a combined magnitude; and
determining whether the handoff is necessary based on the combined magnitude.

Abstract
Techniques for controlling handoffs in a wireless communication system include receiving a location vector from a mobile unit, and determining whether to perform a handoff of the mobile unit based on the received vector. The vector may also include time information related to the time at which the vector was transmitted. The vector may be obtained from a GPS satellite signal or one or more terrestrial stations.
