Claim Text:
1. A method for determining one or more Key Performance Indicators (KPIs) using inferred statistics, the method comprising: monitoring, by a network monitoring device, a plurality of messages for a network interface in a communication network; determining, by the network monitoring device, a Mobile Terminating (MT) count for MT calls for User Equipment (UE) from at least one message of a plurality of messages; determining, by the network monitoring device, a Mobile Originating (MO) count for MO calls for the UE from at least one variable of the plurality of messages; defining, by the network monitoring device, an inferred MT ratio based on the MT count and the MO count; applying, by the network monitoring device, the inferred MT ratio to at least one of a Circuit Switched FallBack (CSFB) idle mode count indicating a number of successful CSFB calls for UE in an idle mode and a CSFB active mode count indicating a number of successful CSFB calls for UE in an active mode to yield an estimated total number of CSFB idle mode successes and an estimated total number of CSFB active mode successes, respectively; assigning, by the network monitoring device, each of the estimated total number of CSFB idle mode successes and the estimated total number of CSFB active mode successes to one or more Key Performance Indicators (KPIs); and providing, by the network monitoring device, the one or more KPIs to a display to cause the display to show the one or more KPIs to a user.
