摘要
为了提高LTE系统越区切换的性能,寻求一种能够提高LTE系统性能的最优切换算法。分别对基于RSRP测量、基于RSRP和RSRQ测量、以及基于RSRQ测量等自适应算法的三种切换算法进行了研究。通过三种算法的分析比较,发现基于RSRQ测量的自适应算法能够减少切换次数并且保证服务质量,因此该算法是一种可以提高LTE系统性能的最优切换算法。
To improve the performance of the handover in LTE system and find the corresponding optimal handover algorithm,we investigated the adaptive algorithms based on RSRP measurement,the RSRP and RSRQ measurement as well as the RSRQ measurement.By comparing the performance of the three kinds of handover algorithms,we find that the adaptive handover algorithm based on RSRQ measurement can reduce the probability of unnecessary handover while maintaining the Qos,thus this is the optimal algorithm to improve the system performance of the LTE system.
