In this Post I'm going to share about Call Set up Time(CST) Optimization in 3G by EFD(Enhanced Fast Dormancy) state transition Optimization in Huawei Network. The step is performed by modify RNC Parameter related EFD state transition by Choose P2F2D rather than P2D transition in CST(Call Set up Time).
P2F2D = PCH to FACH to DCH
P2D = PCH to DCH.
The Background of this activity:
- CS Setup after P2D needs activation time, while P2F2D doesn’t need
- CS RB SETUP Message sent on DCH consumes more time than that on FACH.
(the signaling bit rate of DCH is 13.6Kbps, while the signaling bit rate of FACH is 25.6Kbps).
The step for this activity is just to activate and running command as below Script:
MML(R16):
SET URRCTRLSWITCH: OptimizationSwitch=CS_SETUP_P2D_SWITCH-0;
SET URRCTRLSWITCH: OptimizationSwitch4=RB_SETUP_F2D_USE_AM_RLC_SWITCH-1;
Based on trial in my project, CST improved from 8.8ms to 8.6ms(1%)
Please note this method of CST(Call Set up Time) optimization is not my initiation, but based on expert people in my project and already implemented all RNC's. Hope this post will be use full for you regarding Call Setup Optimization Time. Thanks.
