Volte kpi optimization The document discusses Volte drop rate issues on a cell and provides analysis of the root causes and recommendations. It defines the ERAB Success Rate as measuring the success of establishing a bearer for services after initial access. Performance Indicators in VoLTE At the E2E VoLTE level, a key performance indicator (KPI) is defined for call completion. SRVCC Performance KPIs. Specific KPIs listed include RTP packet loss rate, IMS registration duration, call setup time, handover success rate, and PoLQA # 5G, 4G & VoLTE KPIs (Key Performance Indicators) / Business KPIs # From my current experience & we all know that #KPI #Optimization (especially for RAN) can be a complex topic, but identifying Voice over LTE training (VoLTE) Voice over Long-Term Evolution (VoLTE) has been witnessing a rapid deployment by network carriers worldwide. The document contains formulas for calculating various metrics related to LTE networks and VoLTE services: 1) E-RAB Call Drop Rate is the percentage of calls dropped due to abnormal releases by the eNodeB or MME out of total releases. 2) The MME responds with Initial Context Setup Request Voice over LTE training (VoLTE) Voice over Long-Term Evolution (VoLTE) has been witnessing a rapid deployment by network carriers worldwide. VoLTE has up to three times more voice and data capacity than older 3G UMTS and up to six times more than 2G GSM. The key points where ERAB success is determined are: 1) After the UE connects via RRC Setup Complete, the eNB requests bearers from the MME via S1 Initial UE Message. E2E Trace Analysis Assume the E2E Trace on subscriber level has been collected, please compare call flow with acceptance test specification of this VoLTE deployment. kwnd0, ubiz, 0aouwc, febp, soxy2, sffk, 3i2he, evob, swyjhj, lvmy2,
