Method and apparatus for dynamic load balancing using handoff
First Claim
1. A method of dynamically balancing call traffic (load) of a plurality of subscribers among a plurality of carriers in a multicarrier wireless communication system, the plurality of subscribers in communication with a base-station via the plurality of carriers, the method comprising the steps of:
- classifying each subscriber of the plurality of subscribers within the communication system into a class category based on a metric corresponding to each of the plurality of subscribers; and
balancing the load of the plurality of subscribers among the plurality of carriers based on the class category of each of the plurality of subscribers.

Abstract
To mitigate the adverse affects of the load imbalance phenomenon prevalent in spread spectrum, multi-carrier wireless communication systems, the system beneficially employs the use of handoff as a means for balancing the call traffic (commonly referred to as "load") among a plurality of carriers within the communication system. The multi-carrier wireless communication system monitors a plurality of metrics corresponding to the loading of each of the plurality of carriers in the communication system and, based upon the metrics, will handoff call traffic to and between the plurality of carriers, thereby mitigating the adverse effects associated with the load imbalance, in accordance with the invention.
