LTE多载波网络用户感知平衡策略研究

Research on User Perception Balance Strategy for LTE Multicarrier Network

LTE多载波网采用面向网络的负载均衡配置策略,极易导致"表面看起来网络多载波之间负载是均衡的,而用户在不同载波上感知严重不平衡"的结果。从"用户实际感知"出发,以用户实际感知来评价并优化调整网络。通过对多载波区域的移动性负载均衡策略研究,探索出既能让载波间达到良好的分担效果,又能实现用户感知平衡的参数设置策略,最终实现"不论用户占用哪个网络载波,用户实际感知不变,所有载波上用户的使用感知相同"的目标,能有效提升用户实际感知。

LTE multi-carrier network adopts a network-oriented load balancing configuration strategy,which can easily lead to the result that "load appears to be balanced between network multi-carriers,while users perceive serious imbalances on different carri-ers". Starting from the user's actual perception,the network is evaluated and optimized by referring to the user's actual perception. Through the study of the mobile load balancing strategy in multi-carrier area,it explores a parameter setting strategy that can not only achieve good sharing effect among carriers,but also achieve user perception balance. The goal that "no matter which network carrier the user occupies,the user's actual perception remains unchanged,and the user's perception on all carriers is the same" can be achieved,which can effectively promote the user's actual perception.
