1. A method for dynamic packet polling during a power save mode, comprising the steps of:

  • polling an access point for packets at a first rate on at least one access category;

    determining a polling time-out as a function of a first packet priority; and

    changing said first rate to a second rate in view of a second packet priority if said second packet priority is higher than said first packet priority, wherein changing said rate further comprises the steps of;

    determining if a packet has been transmitted or received on an access category;

    updating a packet time array for said access category;

    determining an overall poll time-out based on an access category with the longest time-out for starting an overall poll-timer; and

    determining a poll time-out based on an access category with highest priority for starting a poll-timer.
