BHCA is total number calls attempted per hour, Times of calls attempted is total number calls made and times of seizure is total calls attempted and given resources.
so when you capture all this items in an hour then the three will be same( if the no congestion). for five minute capture BHCA=5/60* calls attempted in 5 minute period20th November 2007 at 08:24 #49574AyatGuest
many thanks for you , what did you mean by call attempts (made)
i expalined as the next
you mean BHCA (No of Calls made by subecribers who dailed numbers it is not necessary it take resourece . )
Call attempt i do not understand it .
time of seizure calls with resources
plz can you give me example?? thanks again !!!!!!!!!!!!!!!!20th November 2007 at 09:13 #49575AyatGuest
to be more clear
i attached. real data.
Time 11/19/2007 12:00:00 AM – 12:05:00
Times of Call Attempt 3
Times of Seizure 3
Times of Through Connection 3
Times of Reply 3
We note call attempt =time of seizure = through connection= time of reply , i know it isnot necessary to be alaways equal but it indicates good situation
but what does mean BHCA 36
is it No. of calls in 5 minutes ,but not all of them are success calls only 3.
if the BHCA is No of total calld (subscribers dailed numbers) , time of seizure is calls assigment resources , so what about call attempt
i need really your experince and help !!!!!!!!
is the defination of these counters difeerence from MSC part and BSC part ???????????21st November 2007 at 08:44 #49576peter CheropGuest
I repeat my self again
Times of Call Attempt- calls made by subscriber during that period
Times of Seizure- is calls attempt and given resoources( usually same as attempted calls if no congestion)
Times of Through Connection- calls which ring.
Times of Reply- calls which ring and answered
in our case BHCA=60*3/5 =3622nd November 2007 at 07:07 #49577AyatGuest

ratio of your subscribers / population
(nb of people per m2 x ratio subs/population) x mErl/subscribers –> mErl / m22nd September 2008 at 13:08 #49580HostGuest

RTCH_Assign_Success_BH1st December 2008 at 09:43 #49582AjilGuest
Hi pix, whats the difference between RTCH_Assign_Success_BH and RTCH_Assign_Request_BH for the BHCA calculation? i think the second one is more appropriate. isn’t it?
