Hi:
How can I calculate SDCCH Erlang on ir interface.
fadafaGuest
You can run “GENERAL CELL SDCCH REPORT” on Bsc , objtype=CLSDCCH.
You will see there erlang’s value per cells.
MahilchiGuest
For calculating TCH we go for Erlang-B table what table is used for SDCCH calculation?Can Anyone get me a copy of it?
fadafaGuest
I think that there is now some table for sdcch ,we are puting quantity of sdcch like:
4 sdcch for 7 TCH.
neyGuest
Use the Erlang-B table as same as TCH.
n = SDCCH subchannel
such as SDCCH/4 = 4 subchannel, SDCCH/8=8 subchannel
RGuest
You can use the same table as for TCH. Usually, a lower blocking probability is used for SDCCH.What you obtain is the number of sub-channels SDCCH.
A time-slot provides 8 SDCCH subchannels.
If you use a Combined Configuration, you will have 4 SDCCH subchannels in time-slot 0.
fadafaGuest
In General Erlang=(BHCA*MHT)/3600
salmanGuest
i am confused. is there only one sdcch subchannel allocated to one particular user,and is it sharing that one subchannel with eight other users?
