Data drops have increased after second carrier activation. 1st carrier statistics are normal but 2nd carrier sites have high drops. Could you please help?
Thanks.26th April 2012 at 20:05 #68160pixGuest
check 2G & 3G neighbourhood (inc. and out.), CPICH power, trafic distribution… perhaps your second carrier is not taking much AMR traffic anyway, so the call drop% is not relevant.

all parameters and neighbours are same with 1st carrier. There is no problem with CS drops. only PS(hs/eul/r99) drops is high on 2nd carrier.

oh yes, it’s data drops only.
I don’t have any idea, but i’m very interested in this issue too. Let’s hope someone will help 🙂

Which Vendor it is?
We had same problem in Ericsson.
Ask core team do they use direct tunneling for SGSN?
In our case Ericsson it was kind of bag- patch was loaded and drops became normal values-as 1st carrier.27th July 2012 at 19:10 #68164pixGuest

We have the same issue after adding U900 cells on mixed mode with GSM900 as 2nd or 3rd or 4th carrier.
