摘要:
用户在宏蜂窝和毫微微蜂窝之间频繁执行不必要的切换将导致系统掉话率增加,用户服务质量和网络吞吐量降低。提出一种带有负载均衡的自适应切换算法,根据网络综合负载水平自适应调节切换滞后余量,结合网络容量、终端所需容量、接收信号强度、业务类型、移动速度等多目标参数进行综合切换判决。结果表明所提切换算法可有效避免不必要切换的发生,降低切换次数并提高网络吞吐量。
Abstract:
The frequent and unnecessary handovers caused by the movement of user equipment (UE) between Macro Cell and Femto Cell will reduce the quality of service (QoS) of UE and network throughput. A load balancing aware handover algorithm in long term evolution (LTE) is proposed, which adaptively updates handover hysteresis margin according to the comprehensive load level of network. Furthermore, multiple parameters are comprehensively exploited to make the handover decision, such as the residual resource capacity of network, required resource capacity of UE, receiving signal strength, service type. Eventually, simulation results show that the proposed algorithm can effectively reduce the handovers and unnecessary handovers, thus the network throughput can be improved.
