Abstract
A network monitoring node receives one or more data messages regarding User Equipment (UE) from one or more network interfaces for a communication session in the communication network continuously in real-time, determines a subscriber identification (ID) associated with the UE from the one or more data messages regarding the UE, and determines an equipment identification (ID) associated with the UE from the one or more data messages regarding the UE. The network monitoring node further receives a base-key associated with the UE from the one or more data messages regarding the UE, derives a decryption key from the base-key, decrypts a temporary ID associated with the UE from the one or more data messages regarding the UE based on the decryption key, maps the temporary ID with the subscriber ID for the UE, and the subscriber ID with the equipment ID for the UE, and assigns data messages for all further communication sessions to the UE based on the mapping. The Subscriber ID and Equipment ID are preferably assigned to all further communication sessions for that UE. It updates the mapping when changes to the temporary ID or equipment ID occur.
