CSFallback Setup Rate Degradation & CSFallback Delay
Content: CSFB Success Rate & Setup Time Deterioration.pdf 1143,62 kB
Description
For improving IRAT handover success rate, LTE to WCDMA ANR feature was activated. Until the feature activation, handover relation was created manually to the legacy network. And it was causing time wasting and too many missing Inter-RAT neighbors.
The feature was activated successfully and following performance changes happened:
Inter-RAT HOSR improved: from 46% to 96.5%
CS Fallback Setup Success Rate degraded: from 99% to 93%
CS Fallback Setup Time increased: from 7.3s to 8.1s
In the file, you will find reason of degradation and solution.
Note:
All these actions was tested in live network, no any private information will be provided about the operators and defined MCC, MNC, Site Names are conditional and not really exist anywhere. These documents are not internal information and do not belong to any vendor or operator.
