【摘要】:提出了一種LTE系統(tǒng)中事件驅(qū)動M2M業(yè)務(wù)的流量控制隨機(jī)接入?yún)f(xié)議。采用貝塔分布對事件驅(qū)動M2M業(yè)務(wù)建模,通過統(tǒng)計一段時隙內(nèi)的隨機(jī)接入前導(dǎo)碼空閑比來估計信道流量,從而設(shè)計控制因子進(jìn)行流量控制。建模分析了采用該協(xié)議的系統(tǒng)吞吐量和時延性能,與目前在LTE系統(tǒng)中的隨機(jī)接入?yún)f(xié)議的性能進(jìn)行了對比。結(jié)果表明,該隨機(jī)接入?yún)f(xié)議能夠很好地估計系統(tǒng)負(fù)載,通過控制因子減少碰撞,從而顯示出更好的系統(tǒng)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.
