Can you pls explain what are BMA & HYS parameters.?
And How can they reduce SD Blocking?30th November 2009 at 08:35 #59802BijoyGuest
BMA defines how many SACCH multiframes are used in measurement averaging in the BTS.The preprocessing of the measurement results in the BTS
reduces the traffic load of the LAPD links and BCSU units.
HYS defines the received RF power level hysteresis for required cell reselection.Higher the HYS ,less frequent will be cell reselection,and lesser the SDCCH usage for Location update.30th November 2009 at 14:00 #59803safarGuest
anybody know abt like this bma parameter in ericsson?30th November 2009 at 18:18 #59804JaspreetGuest
Thanks a ton @Bijoy1st December 2009 at 09:11 #59805AliAsgherGuest
*A little clarification, HYS is used for cells with different LACs only. That is this hysteresis is applied when reselection is to be made for cells of different LACs. (I thought someone might misunderstand it Bijoy)
Regarding BMA, I think it is used with some kind of feature “MR Preprocessing in BTS” etc. I am unaware of such feature in Ericsson. Please relief me Bijoy 🙂1st December 2009 at 12:09 #59806BijoyGuest
Kindly consider HYS only when reselection happens to different LAC.
Well,”BTS Preprocessing” feature is in all vendors except Ericsson:-).
That’s why I left Ericsson:-)

Thanks again guys
You all are really kind.
