in out network we have applied all the techniques like: remove faulty TRXs , H/W issue,capacity requirements,UL/DL pathloss but still blocking persist.
Plzzz suggest if there is any other cause ASAP.

sheldon…. sorry for the wrong spelling22nd July 2010 at 12:10 #63717HansonGuest
Did you say you have looked at capacity requirements? Typically you’d want to look at the Busy hour traffic and re-dimension the network accordingly, i.e add more TRXs and increase back-haul capacity but bare in mind that this will be capital intensive.
Some questions to answer as well are: What kind of site configurations are you using? Single band or dual band configurations?
From a parameter perspective you might need to go more aggressive on HR and AMR channel activation and on assignment redirection to less congested neighbors.23rd July 2010 at 06:32 #63718DenymonGuest
Have you compare TRX sig & Traffich Channel between BSC configuration and Configuration on BTS configuration?
if problem still persist please swap Base Band & BOI.23rd July 2010 at 07:13 #63719RiMiGuest
we already have activated HR where urilisation is more.
and can u plz tell me wht is the criteria for AMR activation23rd July 2010 at 07:14 #63720RiMiGuest
are u talking abt TCH channel assignment during frequency optimisation? we recently have done this, but problem is still there.23rd July 2010 at 08:25 #63721SHELDONGuest
I think you need to elaborate more so that we can tell where the problem is coming from.
Is the blocking affecting the whole network or just portions of it (eg, a particular MSC, BSC or some cells)? Is your network traffic increasing? Which vendor(s) are you using?

Are you talking about TCH Congestion Rate per cell? Which KPI shows bad values as per your threshold? For sure you need to be specific.23rd July 2010 at 17:41 #63723RiMiGuest
I’m talking about TCH blocking per cell.31st July 2010 at 09:12 #63724su zangGuest
Hi pls tell me about TCH Assinment success rate.25th August 2010 at 10:20 #63725woodyGuest
May be Abis Congestion.
