摘要： 快速增长的网络数据流量加剧了移动通信网中资源的消耗,严重威胁网络的稳定运营。而用户的高频网络访问行为增加了网络资源负载,同时影响移动终端的续航能力。针对上述问题,从资源消耗、激活规律、行为模式等方面,对真实网络中高频数据用户进行研究。分析结果表明,该类用户的资源利用率较低,在产生等量数据流量的前提下会消耗大量信令资源,同时在会话激活间隔上表现出较强的周期性规律,并且45.38%的周期性高频数据用户行为表现异常,对网络正常运营造成极大威胁。

Abstract: With the rapid growth of network usage,mobile communication network is operating under restrictive constraints of resources,seriously threatening the stable operation of network.High-frequency users,who activate/delete data session frequently,consume much more signaling resource and phone power.This paper performs the real-network investigation of high-frequency users from the aspects of resource consumption,activation rule,behavior pattern,etc.,and observes that they are extremely low resource utilization ratio according to low data traffic volume and high signaling overheads.Also,they tend to activate periodic sessions on session activation interval.Besides,a large number of periodical high-frequency users(45.38%) behave abnormally,which greatly threatens the network.

Key words: mobile communication network, high-frequency data user, resource utilization ratio, signaling resource, periodicity
