MEDIUM ACCESS CONTROL METHOD FOR VOICE AND DATA INTEGRATED SERVICE IN CDMA NETWORK

摘要

PURPOSE: A medium access control method for voice and data integrated service in the CDMA(Code Division Multiple Access) network is provided to maximize the efficiency of channels and to achieve the satisfied service quality of voice and data. CONSTITUTION: If the first packet at an idle state(601) is generated(602), the transition of voice and data terminals is made to a pro-active state(603). A base station annunciates cut-off priority to all terminal(604). Each of the terminals transfers reserved packet only in case that its priority is larger than the cut-off priority(605,606). The base station receives the reserved packet with a channel(607). The transition of a terminal of the associated packet successfully received the reserved packet is made to a stand-by state(608,609). The base station annunciates a channel allocation result to all terminals according to the order of priority(610). According to the channel allocation result, a terminal reserved for a channel to transfer transmits the traffic packet using a time division slot and a transfer code(611,612). A voice and data traffic packet transferred to an upward link traffic channel by each terminal is received by the base station(613).
