The correlation effects on service control point response time

Abstract

As the centralized database for the integration across multiple wireless tiers and wireline access, traffic design considerations for SCP performance measurement are of great important in the personal communications era. By neglecting the effect of disk access time, the SCP response time R includes the SCP processing time P and signalling link delay L only. A bivariate normal distribution has been proposed for modelling (P, L) such that some statistical estimations of L given P can be conveniently obtained in different combination of SCP processing load and link utilization. Further, the correlation effects of (P, LP = p) on R are investigated. After a Turkey one degree of freedom test with one observation of mu(LP=p) per treatment (n = 1) under different normalized processing times and correlations, the two-factor ANOVA model becomes an interaction model without pure error effects due to the computed F* values being significantly greater than the critical F(0.95; 1, 11). Besides, rejection threshold criteria of SCP response time with minimum loss rate (0.01 per cent) of messages are proposed to ensure a good service quality of SCP.
