Abstract
Systems and methods include obtaining monitored traffic from an S1 interface; detecting a Secondary Radio Access Technology (RAT) Data Usage Report (DUR) in the monitored traffic; determining whether the Secondary RAT DUR relates to a 5G Non-Standard Architecture (NSA), and, if so, determining an address of a gNodeB in the Secondary RAT DUR; and storing the address of the gNodeB in a database. The systems and methods can include, for a call, updating a Call Detail Record (CDR) to reflect one of 5G NSA and 4G based on whether an address in the CDR is in the database.
