Please would somebody help me? I’d like to know the usual time between the moment you press the “send” button and the time you hear the first ring in a GSM network, I read once that this time should be less than 6 secs in a Mobile to fix call and 12 between two mobile phones call, is this correct? I think there should be a difference if it is local or long distance.
Thanks and regards8th June 2005 at 04:01 #41144sjGuest

our telecom nowadays we installed a news mobile network with a very long routing.At our first mobile-mbile call test it was about 23sec and fixedline-mobile 18 sec.
Really it was very terrible,but fortunately we pushed eventually into superfast call only 2sec for mobile-mobile and 3sec for fixedline-mbile6th July 2005 at 11:24 #41146subokGuest
2sec and 3 Sec….this is impossible7th July 2005 at 09:57 #41147anbooGuest
Even in lab scenario 2 Seconds is impossible unless we skill all the software processing.. signaling etc.,

Usually the call set up time varies fom 6-8 secs17th September 2005 at 12:49 #41149bokoGuest
We use automated vehicle mounted equipment to measure call setup delay from the subscriber perspective. Our values are 6.5 MOC GSM-ISDN (internal) and 7.8 for MTC (ISDN->GSM).
It can be longer if you use compression between different MSC26th January 2011 at 11:30 #41150SANJIBGuest
One of the solution is hard reset.
Just remove the DRUs of particular cell one by one and check after that.
Reason:- Because the DRUs are running by software and possible that the software may be hang.
when u remove & re-insert the DRU it will automatically “HARD RESET”. bcoz there is a small pin behind the DRU. So when u re-insert it will automatically hard re-set and start loading software from BSC.
When u reset from front i.e “SOFT RESET”. The dru will b reset but not the Rx power it is radiating.
So don’t worry. Just remove & re-insert the DRUs.21st January 2012 at 11:16 #41151NasserGuest
Is there a tool to measure call setup delay/ post dial delay. If yes please let me know.
Or if anybody know any other means of measuring this indicator or if you know a formula to calculate this, please let me know if you don’t mind.21st January 2012 at 11:18 #41152NasserGuest

Call setup time is poor(i.e taking more time) in whole BSC. can anyone tell me the possible reasons and possible solutions for that.13th June 2012 at 12:40 #41154rkcGuest
-call setup delay is being reported through field measurements ie DT ?
-through switch measurements ?
-or its customer percieved ..delay being reported by subscribers ?
