1. A method comprising:
receiving, at a policy control function (PCF) device, a first request to establish an access and mobility (AM) policy control association in relation to an establishment of a data session requested by a user associated with a user equipment (UE) device;
generating, by the PCF device, a query to a network device via a network interface, for AM policy control data and at least one of UE policy control data or session management (SM) policy control data;
receiving, at the PCF device, the AM policy control data and the at least one of the UE policy control data or the SM policy control data from the network device, wherein the SM policy data includes multiple SM policy rules;
identifying, by the PCF device, a subset of the multiple SM policy rules for enforcement;
rendering, by the PCF device, SM policy decisions for each of the SM policy rules of the subset;
creating, by the PCF device, the AM policy control association based on the received AM policy control data; and
sending, by the PCF device to the network device, a second request for a notification of a change to any of the AM policy control data, the UE policy control data, or the SM policy control data.
