Abstract
Systems, devices, and methods for resolving the original private Internet Protocol (IP) address of a User Equipment (UE) device in a cellular communication network; particularly where the UE device is behind a Network Address Translation (NAT) service which replaces the original private IP address of the UE device with a replacement public IP address. An IP address resolver performs an active resolution process which injects a new IP packet to the network, or performs a passive or comparison-based resolution process which compares headers of IP packets, to determine a pair of (i) an original private IP address of a particular UE device, and (ii) a replacement public IP address that is assigned to the UE device by a User Plane Function (UPF) unit. The correlation data or IP address mapping data is provided to servers or applications, to enable them to provide services to the UE device using its original private IP address.
