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.
Claims20
A non-transitory computer-readable medium having instructions stored thereon for programming a processing device to perform steps of:
- 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.
A method comprising:
- 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.
A processing device comprising:
- one or more processors and memory comprising instructions that, when executed, cause the one or more processors to
- obtain monitored traffic from an S1 interface;
- detect a Secondary Radio Access Technology (RAT) Data Usage Report (DUR) in the monitored traffic;
- determine 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
- store the address of the gNodeB in a database.
