在未来移动互联网中
异种网络之间的密切合作将为用户提供无缝的业务链接.终端移动与业务到达的突发性造成了网络负载在时空域的不均衡分布
成为影响网络性能的重要因素.自适应的无线接入控制机制是均衡异种网络负载、提高无线资源利用率的有效途径.首先
本文提出了一种新的基于终端移动与业务到达认知的动态负载均衡策略.然后
根据业务到达的统计分析结果
通过终端分类与移动建模
创建了一种基于用户小区驻留时间的自适应无线接入控制机制.最后
仿真结果验证了该机制的有效性.
In future Mobile Internet
co-operation among heterogeneous networks will provide users with seamless services.Mobility of terminals and burst arrival of services cause disproportional network load distribution in time and space domain
which is a key factor influencing network performance.Adaptive radio access control scheme is an effective approach for load balancing among heterogeneous networks
improving utilization of radio resources.Firstly
a new dynamic load balance policy based on terminal mobility and service arriving cognition is proposed.Furthermore
according to statistic analysis of service arriving data
an adaptive radio access control scheme based on users' cell resident time is raised.It is realized through terminal classification and mobility modeling.Finally
performance of the above scheme is verified by simulation results.
