Common divisor of the offered traffic Figure Memory vs memoryless MsCAC systems. that the offered traffic of class 1 is 7Ấ Erlangs class 2 is 2Ấ Erlangs and class 3 is Ấ Erlangs. Thus the total offered haffic is 10 Erlangs if Ấ 1. Figure presents the new-call blocking as well as the handoff failure probability of each service class in MdCAC and MsCAC systems vs the common divisor of the offered traffic intensities of hie service classes in 4 3 3 MTIP. This figure confirms that there is no capacity gain using MsCAC for srming CBR shows the need for stable and reliable menssoomenfs in MsCAC systems. The performance characteristics of a memoryless measurement-based and a memory auto-regressive measurement-based system are presented also for 4 3 3 MTIP. Estimations with the help of auto-regressive filters may results in better performrnnr butmore somplex hardware software is needed.

SCAC system in comparison with the MdCAC system for 4 3 3 5 4 1 and 7 2 1 MTIPs respectively. Figure demonstrates that the SCAC systemwith the incomplete Gamma decision function offers better average communication quality but slightly worse equilibrium blocking and dropping characteristics compared wit1 die Gaussian function.
