Abstract
Various embodiments comprise a wireless communication network to qualify user devices for network policy association. In some examples, the wireless communication network comprises a network data system. The network data system receives an equipment identity check request transferred by a control plane that comprises an International Mobile Equipment Identifier (IMEI) for a User Equipment (UE). The network data system reads the IMEI to determine a Type Allocation Code (TAC) for the UE. The network data system compares the TAC for the UE to an IMEI TAC database indicating when Policy Control Function (PCF) registration is available for the UE and determines when the PCF registration is when is available for the UE. The network data system transfers an equipment identity check response that indicates when the PCF registration is available for the UE to the control plane.
