- Case: The global Network SRVCC SR has had a poor performance, below 96%. This old problem affects the Mobility from LTE to 3G when VoLTE Call is active. SRVCC SR in North Region is below 50%.
- Solution: We delivered a massive alignment of RAN Mobility Parameters LTE-3G, LTE-LTE. Transport QoS corrections. LTE EPC TAC reconfigurations.
- Result: SRVCC Improvement the Central Region 73% to 96%. RAN SRVCC North Region improve from 42% to 99%.
- The SRVCC SR for Core increase in all regions, especially in the Central Region 73.02% to 95.80%.
- The SRVCC SR Global increase in all regions, especially in the North Region +35.97%.
- The SRVCC SR for MOCN scenario increase in all regions, especially in the North Region from 42.70% to 99.13%.
- The SRVCC Success Events for TEF increase in all regions, especially in the Central Region +119.42%.
