切换是移动性管理的重要组成部分。在LTE-Advanced系统中,由于中继、载波聚合等新技术的引入,给系统的切换机制提出了更高的要求和挑战。通过对传统LTE-Advanced系统和LTE-Advanced中继系统切换过程的分析,提出了LTE-Advanced中继系统基于辅助载波的协作切换算法。该算法利用低频载波传播范围广、高频载波资源相对较多的优势,并结合中继技术和载波聚合技术,达到了降低切换中断概率、提高系统吞吐量的目的。
Handover is one of the most important parts in mobility management.In the LTE-Advanced system
more new technologies such as relay and carrier aggregation and so on were introduced
which put forward higher requirements and challenges to the handover mechanism of system.The handover process of the traditional LTE-Advanced system and LTE-Advanced relay system were analyzed
the cooperative handover algorithm based on auxiliary carrier in LTE-Advanced relay system was proposed.This algorithm makes use of the advantages of wide spreading of low-frequency carrier and rich resources of high-frequency carrier
and in conjunction with relay technology and carrier aggregation technology
achieving the purpose of reducing the handover outage probability and improving the throughput of the system.
