If you are asking me then I dont have it. I'm afraid you'll have to wait till summer as I get a break in june and thats when I'll have enough time to make Matlab simulation for the call setup

call setup by ms gsm

tai,

You try to download the paper I upload earlier and see is the call flow is clear enough for you to understand the process.

After understanding the flow, then you need to study the definition of each release cause, then only you can understand why they are failed.

Hi Experts,

I would like to know the process of Call setup and how to reduce the CST. In GSM average CST is 3.5 to 4 sec. Bt in our network we are getting it higher. As it is not in our hand only NSS pplz can help so to clear my knowledge kindly extend you support.
