Abstract :
Intelligent assignment of voice and data calls to RF carriers in CDMA systems can increase spectral efficiency. This paper proposes policies for realizing this benefit in systems where there are multiple call classes, arbitrary call hold time distributions, and state information is only periodically available. A significant amount of additional benefit results from these policies when an estimate of the call hold times distribution is used in the call assignment decision. Both analysis and simulation are presented
