Claim:
1. A method for subscriber mapping in a communication network in real time continuously, comprising: receiving, by a network monitoring node(s), one or more data messages regarding User Equipment (UE) from one or more network interfaces for a communication session in the communication network; determining, by the network monitoring node, a subscriber identification (ID) associated with the UE from the one or more data messages regarding the UE; determining, by the network monitoring node, an equipment identification (ID) associated with the UE from the one or more data messages regarding the UE; receiving, by the network monitoring node, a base-key associated with the UE from the one or more data messages regarding the UE; deriving, by the network monitoring node, a Non-Access Stratum Encryption (K decrypting, by the network monitoring node, a temporary ID associated with the UE from the one or more data messages regarding the UE based on both the K mapping, by the network monitoring node, the temporary ID with the subscriber ID for the UE, and the subscriber ID with the equipment ID for the UE; assigning, by the network monitoring node, data messages for the communication session to the UE based on the mapping; and assigning, by the network monitoring node, the subscriber ID and the equipment ID to further communication sessions associated with the UE.
