【摘要】:提出了一种LTE系统中事件驱动M2M业务的流量控制随机接入协议。采用贝塔分布对事件驱动M2M业务建模,通过统计一段时隙内的随机接入前导码空闲比来估计信道流量,从而设计控制因子进行流量控制。建模分析了采用该协议的系统吞吐量和时延性能,与目前在LTE系统中的随机接入协议的性能进行了对比。结果表明,该随机接入协议能够很好地估计系统负载,通过控制因子减少碰撞,从而显示出更好的系统性能。
[Abstract]:A traffic control random access protocol for event-driven M2 traffic in LTE system is proposed. The event-driven M2M traffic is modeled by Beta distribution. The channel flow is estimated by counting the idle ratio of random access preamble in a time slot, and the control factor is designed for flow control. The throughput and delay performance of the proposed protocol are modeled and analyzed, and the performance of random access protocol in LTE system is compared with that of the current random access protocol. The results show that the random access protocol can well estimate the system load and reduce the collision through the control factor, thus showing better system performance.
