1. A method for reducing voice latency in a voice-over-data wireless communication system, comprising the steps of:

  • generating a plurality of data frames;

    dropping one or more of said plurality of data frame to keep a plurality of remaining data frames, wherein said step of dropping further comprises;

    determining a voice frame integrity;

    comparing said voice frame integrity with a predetermined value, said predetermined value representing a minimum desired voice quality;

    increasing a variable queue threshold if said voice frame integrity is less than said predetermined value;

    decreasing said variable queue threshold if said voice frame integrity is greater than said predetermined value;

    dropping times at a first rate if a length of said queue is less than said variable queue threshold;

    dropping frames at a second rate if said length is greater than said variable queue; and

    storing said plurality of remaining data frames in a queue.
