Pls give definations of Answer seizure Ratio & Call success Ratio with examples. that is with some numbers which will explain both .19th December 2003 at 18:06 #36904Balakrishnan S NaickerGuest
I think anwser siezure ratio & call success ratio might be same. Please carify me , if i am wrong.
Answer Bid ratio = (Number_of_answered_calls/Number_of_Bids) * 100
Answer Seizure ratio = (Number_of_answered_calls/Number_of_siezure) * 100
Bids = Call attempts
Siezures = Attempts which got/sieze the connections
Answered = Attempts which got the connections and anwsered.21st December 2003 at 06:17 #36905shivanandGuest
Thank you very much

ASr and CSR are deffent.
ASR=Answerd calls/ Seizured calls
If you have ofer flowin your trunks you shold add that aslo along with sezures.
CSR=Call success/Call attempts
normally in anetwork CSR will be 97%.But ASR will be between 30to 50% only. In my netwok i observed CSR of 98% and ASR 35%30th December 2003 at 11:55 #36907Balakrishnan S NaickerGuest
Thanks for your clarification.
What I understood your reply is Call Success Ratio is nothing but ABR. Pleas correct me, if i am wrong. Thanks.30th December 2003 at 12:21 #36908SujeeshGuest
What i mentioned as CSR is call setup success ratio.30th December 2003 at 16:26 #36909Balakrishnan S NaickerGuest
When do you say a call is success,
(i) if an attempt gets the connection
(ii) if an attempt is answered??
In the 1st scenario,
CSR is not ABR
But in the 2nd scenario,
Please clarify me in details, if I am wrong.31st December 2003 at 10:57 #36910sujeeshGuest

hi Sujeesh & Balakrishnana
Thanks for the Discussion threads,
I think the idea is a bit clear now abt CSR related to BTS & MS in a wireless network.
But what about CSR & ASR in CCS7 network ?
Because though the CSR at BTS end is 97% call failure is lot especially Call drops especially on 31st of Dec. that is I believe MSC resources were not available that is SM’s in this cases for CCS7 what should be the definations?
