Transmission of voice in an EDGE network
Jianjun Wu, K. Samaras, Cristian Demetrescu, Ruoxin Yan · 2002
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/spl sim/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, a fast access mechanism for uplink transmission is introduced to guarantee the quality of service for voice.
