Priority messaging method for a discrete multitone spread spectrum communications system

A highly bandwidth-efficient communications method, comprising the steps of:

• receiving at a base station a first spread signal comprising an incoming data traffic signal having a data portion spread over a plurality of discrete traffic frequencies;
• receiving at said base station a second spread signal comprising an incoming message segment signal having a message segment portion and a priority interrupt flag portion spread over a plurality of link control frequencies;
• adaptively despreading said first spread signal received at the base station by using despreading weights, recovering said data portion;
• adaptively despreading said second spread signal received at the base station by using despreading weights, recovering said message segment portion and said priority interrupt flag portion;
• resetting a message segment buffer in said base station and storing said message segment portion therein, if said priority interrupt flag has a first value;
• concatenating said message segment portion with a previously received message segment, if said priority interrupt flag has a second value.
