Guys Urgent help required. Which should be larger if you take a BSC into consideration:- Total no of attempts from subscriber till BSC OR the traffic from BSC to MSC.
Or should it be same.17th March 2010 at 13:46 #61542PixGuest
i’m not sure i understand the question… my answer is “it should be the same”17th March 2010 at 17:02 #61543gemGuest
The case is I am taking erlang counter on the BSC which comes to x. Now when I take the CGR report of that particular BSC ie, (AMR and non AMR circuit), I get an erlang y which is less than x
Surprisingly,when I take the calls in the BSC and compare it with the total of “Call in” and “call out ” of the the AMR and non AMR CGRs, i get a value 60000 more than that of total calls.
I am confused18th March 2010 at 07:59 #61544BijoyGuest
The Switch traffic will always be slightly less than the radio traffic.
Regarding Call in BSC,I think you consider only the MO & MT,& not the inter BSC incoming HO calls,whereas in CGR,i think you count the CGR switching calls too,as well as the incoming HO calls from other BSC’s.

Thanks Bijoy for the reply.
OK so you mean to say, I shouldnt be taking the CGR report.
So which counter will give me the correct picture on how many calls are there in ater so that handover attempts gets avoided18th March 2010 at 09:54 #61546BijoyGuest
What is your vendor?I think every vendor has separate counters in BSC for MO,MT,incoming HO calls.I’m not so sure about the calls demarkation in CGR,some vendors do have,some dont.
Bijoy18th March 2010 at 10:04 #61547GemGuest
Vendor is Nokia. COunter name at CGR level would be required18th March 2010 at 10:22 #61548BijoyGuest
Please check the p_nbsc counters in BSC to have exact no. of calls for MO,MT & Incoming HO from other BSC’s
Bijoy19th March 2010 at 04:45 #61549GemGuest
Bijo, On a second thought, handover doesn’t seem to be the correct root cause.
We are looking at that particular BSC CGR only19th March 2010 at 04:52 #61550BijoyGuest
Then how does the incoming HO to that BSC from other BSC’s & the intra CGR (say AMR-AMR or NAMR-AMR) HO is accounted for as they need a circuit too in that BSC.
Bijoy19th March 2010 at 10:56 #61551GemGuest
Even if a sub moves from a different BSC to “our” BSC, the channel in the air would also get used which means a TCH is allocated and hence increases the no of calls in that BSC.
Suffice to say that a inter BSC handover would result in a channel in the air as well as ater simultaneously
What do you think19th March 2010 at 11:13 #61552BijoyGuest
Take the total “IN” & “OUT” calls from CGR.
Also,take total “MO”,”MT” & “IncominG HO calls from Other BSC” for that BSC.They should be exactly equal.
I think,The total calls you are taking doesn’t comprise the Incoming HO calls from other BSC.
Bijoy19th March 2010 at 11:15 #61553BijoyGuest
Even your total calls will match in CGR & BSC,dont think that CGR traffic will be equal to the BSC radio traffic.
The CGR Traffic will always be less than the BSC radio traffic.

Yes Bijo.. I get it now. Checked it with the raw reports .Thanks a lot for the guidance25th January 2012 at 06:20 #61555Naimish MalhotraGuest
What is the full form of CGR?
Whts d exact function of it?
