How to determine the idle duration of random access procedure of NB-IoT system?

I want to simulate random access process of NB-IoT by Markov chain. When packets arriving at idle UE and this will lead to the UE from idle state to active state. Besides, packets arriving follow Poisson process. Then my question is in this condition how to determine the time duration of Poisson process?

Thank u.

Why multiple UEs select the same preamble and all of them can receive RAR in random access procedure ?

In LTE random access procedure, if multiple UEs select the same preamble and send it to BS, there may have two conditions:
First, if these UEs have enough SNR, BS can detect a collision happen, then BS do not send RAR.
Otherwise, second, these UEs have a collision and BS can not detect all of them and send RAR, and all of these collision UEs can receive the same RAR.
My question is about the second one, there are multiple UEs use the same preamble, why BS do not know the collision ? why BS still send RAR to UEs ? why BS can still detect this preamble?

LTE: What type of random access procedure is executed during handover procedure ?

If my understanding is correct then as part of handover procedure, UE can do either contention based rach or non-contention based.
Now my question is that on what parameter basis target eNodeB decide for an UE to do contention/non-contention based rach during the handover procedure ?
