Abstract

Capacity of CDMA system depends on an interference level in the system. There are therefore RRM (radio resources management) functions, which are responsible for supplying optimum coverage, ensuring efficient use of physical resources and providing the maximum planned capacity. A call admission control algorithm based on load factor evaluation and a fuzzy logic based call admission control algorithm are presented and mutually compared in this contribution.
