碩士 === 大同大學 === 資訊工程學系(所) === 99 === Hierarchical Cellular Network architecture (HCN) is the most common architecture that widely used in the mobile telecommunications operation. Channel assignment is the key issue to improve System performance. Different kind of traffic types is applicable to recent proposed methods such as guard channel, overflow and subrating. But in real world, these traffics are intermixture. A fuzzy model for Self-adaptive Subrating Channel Assignment could trigger subrating ratio and overflow method. In the complex traffic environment, this channel assignment strategy can provide better performance on block, handoff failure, and system channel utilization.
