摘要
物联网通信系统在承载具有突发特征的终端数据业务时,不可避免遇到热点终端因无法响应数据信令请求而引发系统阻塞等一系列服务质量(QoS)劣化的情形。文中在研究传统算法的基础上提出了一种阈值判断和转移可选的协作机制。该机制首先通过一定的计算方法建立可用的目标邻区库和需要进行载荷流量转移的热点终端库。然后为目标邻区库和热点终端库建立匹配关系。再根据次序实施流量载荷的协作转移。最后设置测试参数建立测试模型,通过三项指标的多次实验,考察协作转移机制在物联网通信系统中为热点流量实施载荷转移的优势。
When the Internet of things communication system is carrying terminal data service with burst characteristics,it is inevitable to encounter a series of( QoS) deterioration cases such as network congestion caused by the failure of hotspot terminals not responding to data signaling requests. Based on the study of traditional algorithms,this research presents an optional mechanism for threshold judgment and transition. The mechanism firstly establishes an usable target neighbour cell database and a hotspot terminal database which needs load flow transfer through a certain calculation method. A matching relationship between the target neighbour all database and the haspot terminal database is established.Then according to the order,the collaborative transfer of traffic load is carried out. Finally,the test model is established by setting up test parameters,furthermore the advantages of the cooperative transfer mechanism in implementing load transfer for hotspot traffic in the Internet of things communication system are investigated through several experiments of three indexes.
