(d) Call request rate and set up time

I have been asked this question in an interview for job.

I need to ask this question from Trunking and Grade of Service in chapter The Cellular Concept – System Design Fundamentals of Wireless/Mobile

Answer 1

The correct choice is (b) Call request rate and holding time

The explanation: The traffic intensity offered by each user is equal to the call request rate multiplied by the holding time. Each user generates a traffic intensity A=λH Erlang. Here, H is the average duration of a call and λ is the average number of call requests per unit time for each user.
