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

Introduction Of Teletraffic Engineering

Introduction Of Teletraffic Engineering Telecommunications traffic engineering ,  teletraffic engineering , or  traffic engineering  is the application of traffic engineering theory to  telecommunications . Teletraffic engineers use their knowledge of  statistics  including  queuing theory , the nature of traffic, their practical models, their measurements and  simulations  to make predictions and to plan telecommunication networks such as a  telephone network  or the  Internet . Traffic is defined as a total number of call passing through over a trunk.Channel is defined as a transmission medium.The field was created by the work of  A. K. Erlang  for  circuit-switched  networks .A good example of the use of teletraffic theory in practice is in the design and management of a  call center . Call centers use teletraffic theory to increase the efficiency of their services and overall profitability through calculating how many operators are really needed at each time of the day.Que

This is Agner Krarup Erlang Erlang     An Erlang is a unit of telecommucications traffic measurement.    An Erlang is defined as the average number of simultaneous calls on a system during one-        hour period.    Erlang defined as the traffic carried by a  group of trunks      In honor of Agner Krarup Erlang What is Erlang?      Erlang = 1 call hour / hour     1 Erlang = 1 hour ( 60 minutes) of traffic   Erlang = (calls/busy hour) x holding time                          Tips: units must be the same ! Erlang Example Question A subscriber makes 3 phone calls of 3 minutes, 4 minutes , and 2 minutes duration in 1 hours period. Calculate Minutes of traffic in the hour = number of calls x duration Minutes of traffic in the hour = (4min+3min+2min) Hours of traffic in the hour    = 9 minutes / 60 minutes Hours of traffic in the hour   = 0.15 Traffic of traffic in the hour  = 0.15 Erl
