Abstract

A wireless communication access node (WCAN) device includes radio frequency (RF) circuitry, RF interface (I/F) circuitry, network communication circuitry, memory, and/or processing circuitry. The WCAN device facilitates communications of a wireless communication device (e.g., User Equipment (UE)) in accordance with a policy profile record associated with the wireless communication device (e.g., policy profile record may be retrieved from a distributed cloud database that is distributedly implemented within the mobile backhaul communication system). The WCAN device collects communications statistics based on the communications of the wireless communication device and updates a communications statistics record associated with the wireless communication device within the distributed cloud database to include the communications statistics that are collected based on the communications of the wireless communication device. The distributed cloud database stores policy profile records and communications statistics records for various wireless communication devices including the wireless communication device.
