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.
Claims14
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) based on a mobility trigger in the Secondary RAT DUR, and, if so, determining an address of a gNodeB in an E-UTRAN Radio Access Bearer (ERAB) Modification Indication in the Secondary RAT DUR;
- and
- storing the address of the gNodeB in a database that is queried to determine if a subsequent address, in another ERAB Modification Indication, is in the database such that the subsequent address has a mobility type of 5G NSA, and, if the subsequent address is not in the database, the mobility type is 4G.
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) based on a mobility trigger in the Secondary RAT DUR, and, if so, determining an address of a gNodeB in an E-UTRAN Radio Access Bearer (ERAB) Modification Indication in the Secondary RAT DUR;
- and
- storing the address of the gNodeB in a database that is queried to determine if a subsequent address, in another ERAB Modification Indication, is in the database such that the subsequent address has a mobility type of 5G NSA, and, if the subsequent address is not in the database, the mobility type is 4G.
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) based on a mobility trigger in the Secondary RAT DUR, and, if so, determining an address of a gNodeB in an E-UTRAN Radio Access Bearer (ERAB) Modification Indication in the Secondary RAT DUR;
- and
- store the address of the gNodeB in a database that is queried to determine if a subsequent address, in another ERAB Modification Indication, is in the database such that the subsequent address has a mobility type of 5G NSA, and, if the subsequent address is not in the database, the mobility type is 4G.
