1. A method of operating a wireless data network to equalize latency for a user application, the method comprising:

  • a source application controller exchanging application data with user communication devices over one or more source wireless access points for a user application session;

    the source application controller maintaining an uplink equalized latency within an uplink latency window and maintaining a downlink equalized latency within a downlink latency window on the application data exchanges for the user application session;

    the source application controller identifying a handover event for at least one of the user communication devices and responsively determining if the uplink equalized latency can be maintained within the uplink latency window and if the downlink equalized latency can be maintained within the downlink latency window;

    the source application controller handing over the application session to a target application controller when the uplink equalized latency cannot be adequately maintained within the uplink latency window or when the downlink equalized latency cannot be adequately maintained within the downlink latency window;

    the target application controller exchanging subsequent application data with the user communication devices over the one or more target wireless access points for the user application session; and

    the target application controller maintaining the uplink equalized latency within another uplink latency window and the downlink equalized latency within another downlink latency window on the subsequent application data exchanges for the user application session.
