purpose of media gateway in 3g is to carry payload and to bridge between different transport technologies.it can be considered as a switch between two transport modes.for example suppose a caller from PSTN network call a 3g subs.the payload from PSTN may be TDM is converted at media gateway into IP/ATM payload for its further propagation upto MS.
NODE B TO RNC payload over ATM as VCIs.

In term of 3G KPI.

BEN21st December 2006 at 05:08 #45621Wilibrordus HerbowoGuest
too many parameter/item on 3G KPI, as I know, since there are dominants SC/server, it looks OK.
AS = active set and NS = neighbor set.

Thanks for your answer.
My point is what dose affect this KPI.
“the number of Scrambling Code in the Active Set”
Take exemple, if we see in area that the % of SC in AS is 65% equal to 5 => waht we can say in this case ?
BEN22nd December 2006 at 06:33 #45624Wilibrordus HerbowoGuest
as I know, 3G has mas 3 SC on AS.
it might be CDMA 1x can have 5 SC on AS.
Yes, many SC can effect KPI (like interfere, capacity)
And I think 3/5 SC on AS depend on handset as rake receiver.25th December 2006 at 07:02 #45625AhmadGuest
