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 network, the intelligent terminal becomes increasingly popular. How to switch between the available interfaces of the terminal according to the different communi-cation speed, the link status, the communication costs of different networks and the characteristics of dif-ferent types of service constitutes a new challenge. This paper presents an Android-based method, with which the witch switches the access network legitimately by collecting and analyzing the traffic characteris-tics of the current service and the current network link status. Finally, by using a mobile phone and a com-puter to build and test the system, the reasonable selection of access network based on traffic characteris-tics could be realized.
