Hi Experts,
From the perspective of local operators, how can we determine whether failed international calls are due to the international telecom voice carrier (such as submarine cables) or caused by issues with the local carrier in the destination country?
In other words, is there an equation or method to calculate the unsuccessful international call attempts in mobile networks?
Thank you!
I have little knowledge on this topic, but typically, there is a carrier between the source and destination, and that carrier is responsible for conducting the initial investigation to identify the issue’s source.
Additionally, you can perform a simple trace for a test call to determine which IP the failure is originating from.
Thank you. I understand that, but can the local MNO receive call success information instantly, or do they need to wait for long-term data from the submarine or satellite carriers?
In other words, is this information accessible in real-time from the local MNO’s NOC, not just for individual calls, but for all failed calls collectively for KPI calculation purposes?
I’m not entirely sure, but there are certain call KPIs, like NER (Network Efficiency Ratio) for MAP.
However, I’ll need to check the formula first to confirm.
