异构小蜂窝网络移动性管理研究综述
Survey of mobility management in heterogeneous and small cell networks
摘要
Abstract
The next-generation mobile communication networks have been evolving into high dense,amorphous and hetero-geneous networks,and mobility management (MM)is becoming one of RRM’s key challenges in heterogeneous and small cell networks (HetNets).MM aims to achieve continuity and seamless handover of UE mobile communications services and reduce signaling overhead,etc.In this paper,we describe the general problem of mobility management.Based on the key aspect of mobility management,a comprehensive classification of mobility management is provided subsequently,with the following three classes:improving overall handover performance,improving small cell discovery/identification,and impro-ving the performance of radio link re-establishment.In addition,we present a detail overview and comparison for mobility management enhancement schemes which were proposed by 3GPP members in recent years.Finally,existing problems and open research issues are highlighted and a summary of the present study is given.关键词
