Abstract: A system and method for GPRS MAC procedures to support delay-sensitive, real-time traffic is presented. The system comprises a mobile station able to transmit packets to and receive packets from a base station, where the base station is coupled to a General Packet Radio Service (GPRS) network, and where the GPRS network is coupled to a data network. In an uplink dynamic scheme, the base station receives an empty packet from the mobile station. The base station releases a bandwidth allocated to the mobile station if an implementation dependent time expires and further allocates a reduced portion of the bandwidth to the mobile station if a number of the empty packets are received or if a control packet requesting additional bandwidth is received by the base station. In an uplink fixed scheme, the base station allocates a fixed number of radio resources to the mobile station.
