Classification: CPC H | IPC H

Claim 8:
9. The medium of claim 1, wherein the instructions further cause the processor to:
capture a third message transmitted over the user plane interface;
extract, from the third message, one of the UL GTP-U TEID or the DL GTP-U TED, a first user plane internet protocol (IP) address, a second user plane IP address, an identifier of one of a user datagram protocol (UDP) or a transmission control protocol (TCP), a first user plane port, and a second user plane port;
capture a fourth message transmitted over the user plane interface;
extract, from the fourth message, the other of the UL GTP-U TEID or the DL GTP-U TED, the first user plane internet protocol (IP) address, the second user plane IP address, the identifier of one of a user datagram protocol (UDP) or a transmission control protocol (TCP), the first user plane port, and the second user plane port; and
determine that the UL GTP-U TED and the DL GTP-U TEID are associated with a same tunnel based on the first user plane internet protocol (IP) address, the second user plane IP address, the identifier of one of a user datagram protocol (UDP) or a transmission control protocol (TCP), the first user plane port, and the second user plane port being the same in the third and fourth message.
