I used this way to simulate the arriving of UEs:
- int array[] with the % of ues per hour.
- int variable with max number of users.
- calculate de number of users per hour: array[i] * maxNumber
- between the time of i and i-1, I add the users with the help of an handler that calls the Attach method and the second that the hander is executedis created with an help of a random generator.
