Adaptive network selection algorithm based on user application profile

In next generation network, various heterogeneous wireless access networks are expected to integrate to support user´s seamless connection. In this system, efficient and reliable network selection schemes are required for users to choose a suitable network among all the available networks. In this paper, an adaptive network selection algorithm based on user profile and application profile is proposed for a cellular and WLAN integrated heterogeneous scenario. In the novel algorithm, user profile information, including user mobility, the power of user terminal, the service cost preference, etc., and the characteristics of user applications are taken into account in designing the cost function factors and the corresponding weights of the network selection algorithm. Comparing to traditional fixed-form cost function based network selection algorithms, the proposed algorithm offers better QoS guarantee and user satisfactory.
