一种支持LTE语音业务的优先级半持续调度机制
Priority semi-persisting scheduling scheme for voice over LTE service
摘要
Abstract
This paper proposes a new scheduling algorithm for allocating the LTE radio resource, Priority Semi-Persisting Scheduling ( PrSPS). PrSPS calculates the priority of the user equipment using the user grade, PRBs needed, average channel quality and average transmission rate. Adopting this priority method in semi-persisting scheduling mechanism can avoid the competition between resource scheduling signalling and voice date, improve the radio resource utilization and scheduling efficiency, increase the user capacity of VoLTE and improve satisfaction of VoLTE users. Using the NS-3 simulation platform, the paper evaluates the performance of PrSPS.关键词
