You can go by this.
Check if equipped SDCCH capacity is sufficient to cater the BBH SDCCH Traffic.If YES,
A)Check for H/W issues
B)High HR Traffic
D)No. of SDCCH configured/TRX
E)Change the LAC boundary if SDCCH usage due to LU is very high.
F)Go for Carrier Augmentation if Cell Utilisation is High
A)Add SDCCH and check.
B)Enable Dynamic SDCCH,if disabled.10th November 2009 at 11:35 #59535prideyGuest

“High HR Traffic” how is it related to SD blk?11th November 2009 at 05:01 #59537BijoyGuest
If HR Traffic is high,signalling load will obviously be higher.(but check first if your HR triggering is rational,you should trigger HR only when FR utilisation is >80%).So,cells where HR Traffic is higher,you need to augment the LAPD signalling from 16 KBPS to 32 KBPS.11th November 2009 at 05:36 #59538guruGuest
