Abstract
There is provided a passive network monitoring device that monitors one or more network interfaces between network nodes including a SGW node, a PGW node, an ePDG node, and a PCRF node and a PCEF node. The device receives a handover indication for UE from untrusted non-3GPP network access to 3GPP network access and receives a response to an attach request from one or more of the network interfaces, the response including a MSIP address and a charging ID for the UE. The device determines the UE is from a single subscriber based on each of the handover, the MSIP address of the response and the charging ID of the response, and correlates information for the UE at each of the one or more network interfaces with the single subscriber.
