Abstract
The method and apparatus of the present invention uses DSI with a TDMA/FDMA communication protocol. For each speech frame detected by a speech detector (110), a communication unit (CU) (108) sends (440) a speech detected indicator (SDI) (208) to a switching facility (SF) (138). In response, the SF (138) allocates an uplink reuse unit (260) which identifies a carrier frequency (301-360) and timeslot (190-193) which the CU (108) should use to transmit a traffic burst containing a compressed speech frame. The SF (138) allocates (506) the uplink reuse unit (260) from a pool of available uplink reuse units and, if necessary, allocates a downlink reuse unit (262) from a pool of available downlink reuse units. A message (220) describing the reuse units (260, 262) is transmitted (508) to the CU (108) which then transmits (450) and receives (480) traffic bursts during the allocated reuse units (260, 262).
