Policy control function (PCF) registration based on device type in wireless communication networks
Various embodiments comprise a wireless communication network to qualify user devices for network policy association. In some examples, the wireless communication network comprises a control plane. The control plane detects a registration request for a User Equipment (UE) and registers the UE for network data services. The control plane receives a device type indication from the UE and determines when Policy Control Function (PCF) registration is available based on the device type indication. When the PCF registration is available, the control plane registers with a PCF, receives network policies from the PCF, and transfers a registration accept message with at least some of the network policies to the UE. When PCF registration is not available, the control plane forgoes the PCF registration and transfers the registration accept message to UE without the network polices.
