Abstract
This paper proposes an efficient adaptive uplink schedule algorithm for Voice over Intemet Protocol(VoIP) services with Adaptive Multi-Rate(AMR) speech codec in LTE systems. In the proposed algorithm, the eNode B adapts uplink resources assignment according to the two reserved bits in the generic MAC header, which is utilized to indicate the mode transition of next frame, The performances of the proposed algorithm in terms of system capacity, throughput, delay of system are analyzed compared with traditional algorithms. Theoretical analysis and simulation results show that the average access delay increases but still meet the VoIP real-time requirements and the algorithm can support much more voice users than the conventional algorithms.关键词
