FUZZY CHANNEL ALLOCATION CONTROLLER HAVING SERVICE QUALITY INSURING

摘要

A fuzzy channel allocation controller having service quality insuring is applied to a hierarchic wireless communication system, which includes macrocells and microcells. A major object of the invention is to dynamically adjust an appropriate threshold value allowing a call to access the system according to the system's states, in order to make the call in progress be able to maintain a certain service quality, and balance the loads of the macrocells and microcells during the channel allocation, so that the system can obtain a higher channel usage. The invention includes: a base interface module, a resource estimator, a performance evaluator and a fuzzy channel allocation processor.
