Abstract
In some embodiments, a non-transitory computer readable medium is disclosed. In some embodiments, the medium includes instructions for providing a mobile user monitoring solution that, when executed by a processor, cause the processor to capture a first message transmitted over an N11 interface, extract at least one type of session ID and a first Next Generation Application Protocol (NGAP) tunnel endpoint identifier (TEID) from the first message, store the at least one type of session ID and the first NGAP TEID in a first N11 protocol data unit (PDU) session record, capture a second message transmitted over an N3 interface, extract a general packet radio service (GPRS) tunneling protocol (GTP)-user plane (U) TEID from the second message, wherein the GTP-U TEID matches the first NGAP TIED, and retrieve information associated with session details record using the GTP-U TEID.
