Hi, yes, we also are experiencing the same. For now no clue what is causing it and how to solve it.
BTW, you are running RU30 or RU40? Also your WBTS SW is 6th or 7th series?

Hi,
maybe someone has a list or information where I could find information about 3GPP standartised 2G/3G/4G features and their mandatory support in MS/UE? Like for example ALL Release 5 UEs MUST...

Hi, you have exSiemens or NSNs Core? We have this problem also in our network (exSiemens core for now) time to times and it's usually due to faulty connections at MSC's side. I have also heard that...

Hi, has someone managed to solve this iPhone 5 issue? We are also facing the same issue (Vendor NSN).

I do not know how much power can be taken by HSDPA in your network, but it looks that you should consider increasing CPICH or FDDQMIN, because 40w=46dBm, CPICH=33dBm and EcNo in cell with HSDPA...

Hi,
first of all, what is your 3G phone penetration? They are 20, 50, 70% of phones in your network?
Regarding how to push traffic to 3G first look at idle parameters, what is your QFDDMIN, also...

Hi, it's hard to tell from so little data, but reasons could be, for example, you have a congestion in better cell (or at least load is over load threshold for HO). It could be due to Priority...

Do your network have Gs interface? On what NMO your network is running and how about Paging Coordination in BSC if you doesn't have Gs?

Hi, anybody finally solved this problem? Maybe you could share final solution?

Yes, mainly open areas with very high customer density (like a fish in a barrel) with 10k-20k sometimes even more customers with 50% 3G phone penetration and 1-5 cells covering the area with 2...

Hi,
I would like to ask for your advice how do you handle congestion and 3G system overload at mass events.
CEs, IuB, DL power, even Ec/No etc are not congested/good, bottleneck is in UL...

Hi,
I suppose Channel required is for SDCCH not for TCH.
Anyway first you should look processes at SDCCH level: how often authentification is done (every call or once every 10th for example), how...

Hi,
no in NSNs TraceViewer you can not activate cell traces. It is possible to activate it for specific cell trough BTS Site Manager but those traces can only be analysed and viewed with NSNs...

Thanks for reply but this is not the case because I see that it also happens for users who are served by only one cell.
It's also not due to cell congestion because it happens to users at 4AM.
My...

Hi,
I am interested in what cases NW initiates UE switch from HSPA resources to R99 DCH? I see in traces that sometimes UE receives RAB reconfiguration but I can't find the reason why. If it's due...

Anyone?
How do you then investigate problems on L3? Please, don't tell me that only with TEMS!

Hi,
I am in need for your help: Can anybody, please, explain how L3 Signalling Message tracing for Subscribers are done in NSNs 2G network? Particularly in BSS part. I am not able to find any useful...

Hi,
I haven't yet worked with NSN 2G equipment but this is pretty universal:
BTS measures interference in every IDLE timeslot (BTS knows when it's idle so there should not be any useful...

Hi,
I am interested in understanding how in 3G systems phones are calculating how many bars to show in given RF conditions? Maybe somebody knows is this specified in 3GPP specifications and what...

One more thing that came up in my mind: how about 16kbps return channel. If it's not enabled then UL overload could be the reason.

Hi, how about CEs, do sites have enought or maybe now there is a lack of them?
Did you try WBTS restart, we have expierenced that after some upgrades etc some sites start to have SW problems and...

I dont't think that Setting T3101 to 5s will improve droprate it probably will only worsen SDCCH congestion because resources will be allocated for longer period of time.
Sudden spikes in SDCCH...

This is the problem, as far as I know, all operators are having (many just doesn't realize it jet :D ).
It's very complex problem where solution could be simple as hell or complex like 3G.
Best way...

Hi,
No N300 7 is normal value and I would not advice you to decrease it because if you do decrease it you will not see it's impacts in your stats (maybe only Paging SSR).
If you fill that your...

Just to specify a little bit SMS delivery:
MS in dedicated mode uses SACCH in 2G associated to TCH it uses.
Otherwise it uses SDCCH.
SACCH doesn't interrupt voice but is used for MR so no MR for...
