How to identify the device type of UE in LTE network?

+1 vote

Is there a way apart from IMEI through which networks (PCRF, MME, AAA etc.) can identify the device type of End User? So that we can apply differential charging?

For the pre-paid customers, sometime operators grant some extra time units (seconds/minutes) even a subscriber is running out of balance. Though I tagged my question to LTE only but this is a very common use case for pre-paid customers. Each operator may have different policy for each user or a common policy for all the subscribers. I am looking for some insights in this area.
