In recent years, network selection has been widely studied when mobile terminal can choose among multiple wireless access networks. But most schemes in current literatures are not suitable for practical usage because they all aim at choosing the best network for terminals which are probably running applications more then one type. Choosing the best network encounters two challenges: 1) How to define the best network; 2) how to allocate the best network. In this paper, we will propose a novel application-oriented network selection strategy which chooses the most suitable network for different applications running in one terminal, then chooses the best network for terminals through investigating the challenges above and considering practical usage. The design goal is to provide users the best QoS, meanwhile utilize network resource more effectively.
