伴随着无线网络的迅速发展,智能终端日益普及。如何根据不同网络的通信速度、链路状态、通信费用以及不同类型业务流的特点等因素,在终端所接入的网络之间合理地切换则成为一个重要问题。提出了一种在Android系统下,通过对当前业务流流量特征的采集分析,同时结合当前各种网络的链路状态对接入网络实现合理切换的控制方法。最后使用Android手机与PC完成了系统搭建与测试,实现了基于流量信息合理选择接入网络的目的。
With the rapid development of wireless networks, smart terminals are increasingly popular. How to switch between the networks accessed by the terminal becomes an important issue according to factors such as communication speed, link status, communication cost and characteristics of different types of service flows in different networks. A control method based on the collection and analysis of the traffic flow characteristics of the current traffic flow and the reasonable handover of the access network based on the link status of various networks are proposed in the Android system. Finally, using Android mobile phone and PC to complete the system setup and testing, to achieve the purpose of reasonable choice of access network based on traffic information.
