ABSTRACT:
A TDMA radio communication system provides communication service to a plurality of mobile communication units through use of a TDMA frame. The TDMA frame includes a plurality of timeslots that are distributed across a TDMA frame duration and are used to facilitate communications involving a first mobile and a second mobile. Audio delays are reduced using a method that includes the steps of measuring a hold time for each of the mobiles, and determining a present aggregate hold time based at least in part on the measured hold times. When the present aggregate hold time exceeds the TDMA frame duration, the method provides for the re-assignment of at least one of the mobiles to an alternate timeslot within the TDMA frame.
