Abstract
An illustrative embodiment disclosed herein is a non-transitory computer readable medium. 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 a packet forwarding control protocol (PFCP) interface, extract a permanent ID and a first user plane tunnel endpoint identifier (TEID) from the first message, store the permanent ID and the first user plane TEID in a PFCP protocol data unit (PDU) session record, store the permanent ID in a session details record, capture a second message transmitted over a user plane interface after the first message is transmitted, extract a second user plane TEID from the second message, wherein the second user plane TEID matches the first user plane TEID, and retrieve the session details record using the second user plane TEID.
