Transmission of Voice in an EDGE Network
01 January 2000
In this paper, a method to transmit the voice over an EDGE system is proposed. New Radio Link Control (RLC)/Medium Access Control (MAC) headers are proposed. To increase the reliability of RLC/MAC headers, an error detection and correction scheme is proposed. The simulation results show that between 12~30% RLC/MAC can be saved due to our new method. The system capacity is increased significantly for voice transmission over a packet switched EDGE network compared to traditional circuit switched network such as GSM. To avoid the extra delay introduced by normal packet switch networks, fast access mechanism for uplink transmission is introduced to guarantee the quality of service for voice.
