GPEH Cause codes

[gagan]

Hello,

I am working on analysis of some GPEH traces from E*******. I have several questions on the cause codes that are populated when the rabs are dropped abnormally (event 438).
At the highest level there are Procedural level cause codes:
Channel Switch Sequence (2 types)
RAB release sequence (2 types)
RAB establishment sequence (2 types)

If someone knows the explanations of these, it would be very helpful if you can share the information.

thanks
Gagan

Hi Gagan,
Besides the Procedural level, you should look into the following parameter

EVENT_PARAM_RAN_DISCONNECTION_CODE
EVENT_PARAM_RAN_DISCONNECTION_SUBCODE

There is a reference table in the Alex GPEH doc that map these release cause to the causes.
