Abstract
Network nodes and interfaces are identified in a combined CDMA/eHRPD and LTE network. Messages captured by a monitoring system on different interfaces are combined in session records. The session records associated with the same network nodes correlated using parameters in the session records. Session records on an A11, A10 and S2a interfaces are correlated using a home network prefix and interface identifier data or home address information.
