Monitoring 3G/4G handovers in telecommunication networks

摘要

Systems and methods for monitoring 3G/4G handovers in telecommunication networks are described. In some embodiments, a method may include 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. The method may also include determining, via the a 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. The method may further include using the telecommunications monitoring system to associate the first packet with the second packet in response to the determination.

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.
