MAX_NUM_UE

[Ghazalmn8]

Hi, great project!
I have a question, is “MAX_NUM_UE“ in “.env” valid for both core and ims?
I mean if i set it 2K will ims handle 2k users as well?

and how many concurrent users and calls have you tested to this? Can I have fore example 2k users and 200 calls?

thanks in advanced

Its purely for Core network. I havent tested that many UEs with IMS

But i know an operator who is using more or less same setup to test 2000 UEs

Thanks for answering
I have another question.

is these parameters affect the number of UEs could be attached to the IMS without performance issue? and if not, which parameters should I change to improve performance?

#!define IPSEC_MAX_CONN

This parameter certainly can be increased to support more IPSec connections reducing the reuse of IPSec server and client ports

I dont think anything else needs to be tweaked. I am currently in the process of adding sipp test scenarios to this repo to load test IMS components (excluding IPSec since sipp doesnt support it). I will let you know once I add it
