Call Intensity

·       Call Intensity,Y, defined as number of calls offered per unit time @ ratio of traffic intensity to call average duration.
·       Formula Y is:

Text Box: Y = A/s
                                                                                       




A- Traffic intensity
s-    Average holding time for a call (unit in second)


         Average Call Duration,S

·       For data, quantity that sent calculated in bit or byte. While transmission speed in second.
·       S is defined as a voice data transmission in second at one channel that have been used OR the average period of service calls.





Call Intensity Example Question

Given traffic intensity of 90E and holding time for a call is a 3   minutes. Find call intensity.

Y = 90E/180s
    = 90E x 3600s / 180s
    = 324K / 180s
    = 1800calls
