摘要：
Two presented Soft HandOff (SHO) algorithms based on Fuzzy Inference System (FIS) aim to increase the values of T_DROP and SHO Window (SHW), and T_ADD, in the first and second proposed algorithms, respectively in order to release the traffic channel at high traffic loads for increasing the carried traffic, and to decrease those values in proposed algorithms in order to add the traffic channel in active set at low traffic loads for increasing the quality of traffic channel. These proposed FIS SHO algorithms can reduce new call blocking probability (P-B) and handoff call blocking probability (P-HO) when compared with IS-95A, IS-95B/cdma2000 SHO and FIS SHO with various fixed SHW and adapted T_DROP while still keeping acceptable low outage probability.
