thats right buddy i want to clear one thing that per pset we can handle 32 tbf total or dl 32 + ul 32 = 64 tbf?
and per pdch we have max 16 in dl and 7 in ul ok.
then if i have 6 fpch + 1 spdch in my one pset then how many can i hadle? is it 32 ?
or per pdch i mean 7 pdch * (16 dl+7 ul tbf) 23?3rd May 2010 at 14:21 #57783SHELDONGuest
The 32 TBFs per PSET applies to each direction (ie, 32 DL, 32 UL).
If you have 7 (or 8) PDCHs in a PSET, the maximum number of TBFs in the PSET is 32 (this is a repetition).

My Friends, we have high congestion in GSL. we changed TBFDLLIMIT and TBFULLIMIT to 10. but high congestion exist yet. throughput is not reasonable. could you please help us to solve this issue. ( we can’t add more PCU)!
Thanks in advance.21st January 2014 at 16:41 #57791SHELDONGuest
With regard to abis allocation, there is no difference between SPDCH and FPDCH. Both are allocated fixed timeslots if you’re using a fixed scheme or dynamically if you’re using flexible abis. The only difference between SPDCH and FPDCH relates to how they are treated on the PCU. The PCU allocates fixed resources (GSL) for FPDCH and on-demand resources for SPDCH.21st January 2014 at 16:49 #57792SHELDONGuest
Sorry about the superfluous post. I was reading the thread in reverse…lol
If you’re having GSL congestion, you should be increasing TBFULLIMIT and TBFDLLIMIT, not decreasing them!
What kind of PDCH allocation strategy are you using? Fixed? On-demand? Semi-dedicated?21st January 2014 at 19:43 #57793pixGuest
thanks sheldon for the clarification on spdch and fpdch. our client is using fpdch and wonder why their BSC are so congested… we’re trying to convince them to use spdch 😀22nd January 2014 at 17:17 #57794EbrahimGuest
Thanks, you are right, we increased the DL and UL TBFLIMIT but LLC Throughput decreased and operators is not satisfy 😀
we are set one FPDCH for each cell.
also on demand is active.23rd January 2014 at 01:35 #57795SHELDONGuest
No problem Pix…we’re all here to share knowledge and experiences. SPDCH is surely the way to go.
If possible, try converting your FPDCH to SPDCH. Depending on the contract you signed with your vendor, this may be free. SPDCH gives you the same advantages as FPDCH, but with flexible allocation of PCU resources.23rd January 2014 at 07:06 #57796EbrahimGuest
tnx. we can’t do it because customer complaint will be increase ;). I want know do you have any more solutions?! 😀
