Also included are network elements receiving the dispersion analysis for the UE mobile device and performing a policy update and/or a radio access network (RAN) decision for the UE mobile device based on at least the dispersion analysis. The technology also applies to 3G, 4G and future mobile networks. ## Claims ### Claim 1 A method of taking into account mobility behavior and interactions with a serving cellular network of a user equipment (UE) mobile device, when determining network interaction parameters for the UE mobile device, including: providing an identifier of the UE mobile device to a network data analytics function (NWDAF) component that subscribes to receive notices that report changed or changing events, including a change in connectivity to any cell for any UE mobile device and any service usage on the cell and performs a dispersion analysis by analyzing the notices to determine dispersion indices as the UE mobile device changes its selection of a base station or cell;
