This paper compares the performance of soft handoff (SHO) between IS-95A and IS-95B/cdma2000 by using the following performance indicators : quality of traffic channel (E/sub b//N/sub o/), outage probability, new call blocking probability (P/sub B/), handoff call blocking probability (P/sub HO/), expected number of base stations in active set (NO/sub BS/), expected number of changes in active set (NO/sub update/) and Trunking Resource Efficiency (TRE) with specific Poisson distributed call arrival and exponential distributed holding time process. By comparison of all parameters, IS-95B/cdma2000 SHOs tends to have a higher performance than IS-95A SHO. Moreover the SHO thresholds affect the triggering and the releasing of 2-way and 3-way SHOs with different distance of both algorithms.
