Hi all!
We are testint for HSPA ( DL, UL) and facing with some problem like this:
1. We use USB datacard & Sim card (support high speed : 14.4M Mbps), but there are many PDP context drop due to UE didn't receive RAB message ( L3 message . and RNC trace)
2. We use USB datacard ( support 7.2Mbps), everything is normal.
3. maybe problem from SGNS, but i don't know exactly which is problem.
So, anybody help me highlight some reason at there
Thanks so much!
