Abstract:
1. A method, comprising: receiving a plurality of packets at a telecommunications monitoring system, the plurality of packets including a first packet following a first version of a protocol and a second packet following a second version of the protocol, wherein the protocol is a General Packet Radio Service (GPRS) Tunneling Protocol (GTP), wherein the first packet follows a GTPv1 protocol and the second packet follows a GTPv2 protocol and wherein the second packet is received after the first packet in connection with a 3G-to-4G handover; determining, via the telecommunications monitoring system, that the first packet belongs to a first communication session that is correlated with a second communication session to which the second packet belongs; using the telecommunications monitoring system to associate the first packet with the second packet in response to the determination; and matching uplink control plane (CP) and user plane (UP) information for the first packet obtained from a Gn interface against uplink CP and UP information for the second packet obtained from an S5 or S8 interface.
