1. A system for implementing a distributed core architecture of a wireless communication network, comprising:

  • a plurality of devices configured to communicate with one or more UE devices to implement the wireless communication network;

    wherein a given one of the plurality of devices includes;

    at least one processor operatively coupled to a memory; and

    a core agent implemented by the at least one processor, the core agent including;

    a controller for controlling functionality of the device;

    a switch operatively coupled to the controller;

    a precomputed policy data store for storing precomputed policies associated with at least security and service;

    mobility and policy applications; and

    a set of core applications including an inter-agent communication application for communicating with other core agents associated with other devices of the wireless communication network, and a control application for controlling the device;

    wherein the core agent is further configured to send a plurality of broadcast update messages to build a consistent network-wide view of UE device states, the plurality of broadcast update messages including;

    a security update to notify the other core agents that the core agent has used a pair of security vectors precomputed for a particular UE device and to request the other agents to invalidate the pair of security vectors;

    a location update to notify the other agents that a particular UE device has attached to the core agent; and

    a policy update to communicate local changes to at least one of the precomputed policies of a particular UE device.
