摘要

通过分析LTE-Advanced系统中基于时隙接入信道控制协议（SCACP）的随机接入模型，提出一种时隙接入方法中接入帧长的优化算法。利用网络实时接入负载实现时隙接入中动态帧长的选择，使得优化后的接入帧长更适合当前接入负载，保障了较高的接入成功率，消除了不必要的接入时延，还在一定程度上减少了前导重传次数。最后通过仿真验证了所提动态帧长选择算法的有效性和实用性。

Abstract

Through analyzing the random access model of slotted access based channel access control protocol (SCACP) in LTE-Advanced system

an optimization algorithm for access frame length selection based on slotted access was proposed. The dynamic frame length selection in slotted access based on network real-time access load was realized. Moreover

the optimized access frame length was more suitable for current access load than before. It could ensure a high success rate of access

eliminate the unnecessary access delay and decrease the number of retransmissions to some extent. The simulation results demonstrate that the proposed dynamic frame length selection algorithm is more effective and practical.
