what is the syatematic way to deal with SDCCH block in a n/w of Nokia equip.
pls give a step by step method pls/Hi,
first check ur hardware.
check the lac boundry
Pridey.
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
C)LAPD signalling
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 HighIf NO,
A)Add SDCCH and check.
B)Enable Dynamic SDCCH,if disabled.thank u bijay . info is useful.
“High HR Traffic” how is it related to SD blk?
Pridey
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.bijay can you tell me how 26&51 frame works and how it is transmitted pls
1.Add SDCCH and check.
2.Enable Dynamic SDCCH,if disabled
3.Check no. of SDCCH configured/TRX
4.Change the LAC boundary if SDCCH usage due to Location update is very high.Guru
Try reading this book as this is quite complex–Mobile radio networks: networking, protocols, and traffic performance By Bernhard WalkeOnce you read,then we can discuss and clear your doubts
How we can that book, dou have link for it!!
