Hi all,
Do you have NSN (RAS/RU) RNC Dimensioning Rule ?
Kindly let me know . If you need anything i ll be ready for exchange.
I found some RNC Dimensioning docs in this forum, but not quite detail.
br
i'm not sure which docs you having. I enclosed some more from NSN, maybe useful for you a little bit

THanks Kamy,
THe result of RNC Dimensioning should be like this, with given number of Node Bs (include CS, R99, HSDPA service) and Traffic Model, the RNC dimensioning should give the result of Number of RNCs needed, the Number Of STM1 required for IuB, Iu CS and Iu PS include the Traffic Descriptor (the bandwidth in CPS), how many VCs needed.

I'm wondering whether what you mean are look like as (example for PS calculation)
4.1.1 Gb Interface
The required bandwidth of the Gb interface is to maximize between the downlink bandwidth of the Gb interface and the uplink bandwidth of the Gb interface.
Downlink bandwidth of the Gb interface = Number of users x Percentage of 2G users x Average downlink traffic for per PDP context x 2G downlink usage factor x Average activated PDP context for per attached user x (1 + redundancy degree)
Uplink bandwidth of the Gb interface = Number of users x Percentage of 2G users x Average uplink traffic for per PDP context x 2G uplink usage factor x Average activated PDP context for per attached user x (1 + redundancy degree)
2G downlink usage factor = (Average size of packets + 56) Average size of packets
2G uplink usage factor = (Average size of packets + 39)/Average size of packets
The redundancy degree is generally 0, but it can be changed to 5% for RFI.
4.1.2 Iu Interface
Required capacity of Iu-PS = (Required capacity of 3G non-HSDPA users + Required capacity of 3G HSDPA users) x (1 + redundancy degree)
Required capacity of 3G non-HSDPA users = Number of users x Percentage of 3G users x Percentage of 3G non-HSDPA users x Average traffic for per PDP context x Average activated PDP context for per attached user
Required capacity of 3G HSDPA users = Number of users x Percentage of 3G users x Percentage of 3G HSDPA users x Average traffic for per PDP context x Average activated PDP context for per attached user

i combined to 1 file:
this is document that i look for :)
Great sharing..

Something like this, but CS dimensioning should be included as well...

share please sir...
we always wait Mr gprastomo's sharing
usually usefull
:)

as you requested, i enclosed the PS calculation formulas.
If it is useful, reps and thanks are welcome.
pw is default.

Thanks Kamy&Paboya,
I just have this kind of doc.
There are some RNC dimensioning Rule also, but i need to read all of document :L .
Anyway, i need more practically :D
br
go on with the bandwidth calculation by excel file.
enjoy,
Kamy

u r welcome Sir...
Here we collect the theory
in field we do the practice ..
But practice without theory is same gambling..
:D
Anyway thanx for great sharing from the both Master
Kamy and gprastomo
Sorry i still cant do something for u all...
just suck ur sharing Sir
:)

thanks (i'm still new in this forum ),It's very useful documents ,i'm working on 3G "BSS" dimensioning.

I want to add rep to Kamy but actually i have to spread to rep first
