Various exemplary embodiments relate to a method performed by a network node for correlating subscriber IDs in a communication network, the method including: receiving a message from another network node that relates to an application function containing information related to a subscriber of the application function; extracting subscriber identification information for the message; determining if the extracted subscriber identification information is found in a correlation object in a correlation object database; if the extracted subscriber identification information is found, then adding the extracted subscriber identification information to the correlation object found in the correlation object database.

LTE subscriber identity correlation service

Various exemplary embodiments relate to a method of identifying a subscriber at a network node. The method may include: receiving a message including a network access identifier (NAI); removing the first digit from the NAI to form a stripped NAI; determining whether the stripped NAI corresponds to a subscriber; determining whether the NAI corresponds to a subscriber; adding a hint digit to form an extended NAI, and determining whether the extended NAI corresponds to a subscriber; and if any of the NAIs correspond to a subscriber, using the corresponding NAI to identify the subscriber. Various exemplary embodiments relate to a policy and charging rules node including: a subscriber cache including a subscriber identifier; an interface configured to receive a NAI; a NAI modifier configured to form an extended NAI and a stripped NAI; and a subscriber identification module configured to determine whether a NAI is stored in the subscriber cache.
