Now there could be a failure at any step. It could be at air interface between the UE and the gNodeB, or it could be between the gNodeB and the core network, or the AMF in that case. Any failure happening between these nodes during the transaction of these messages, which we have seen earlier from the RRC connection to the UE registration completion, there could be a failures and that could lead to the registration failure rate. We understand that these failures can have the issues with the availability, and of course the user authentication or could be the signaling-related problems. There is a formula for that when the first message goes for the UE registration attempt, and once it is…
