Hello All.
What is the recommended value of Inactivity Timer in a LTE cell?

Vendor document mentions the recommended value.
I’ve mostly seen 20ms but some of the high volume cells also had 10ms.
The inactivity timer that I know is usually between 30-60 seconds.
This is the LTE inactivity timer that release the access bearers and requires signaling to set them up again.
You have to be careful with lower value like 10ms, a large number of RRC connection requests could also congest PUCCH.
Actually it is configured as 10 ms in our network.
We observe too many context release due to inactivity timer.
Yes that would happen.
You can check the vendor’s recommended value from the CPI.
Smaller value usually also improves call drop rate but at the same time in high traffic areas, it can degrade the setup success rate.
It can’t be in ms. Must be in second.
10 seconds.
Anything between 2 sec to 10 sec.
30-60 seems like very large numbers.
I have seen around 10sec I guess.
It is generally 10 seconds, but there are features in Nokia which can adaptively select a lower value based on device traffic profile.
Yes you’re right, it’s in seconds not millisecond. 
Can you please tell some feature for this?
