User/Application-Oriented Mobile Terminal Platform and Adaptive Network Selection Algorithms

Next generation wireless network (NGWN) is expected to integrate different access technologies, including cellular network, WLAN and mobile Ad Hoc network, etc. In NGWN, the heterogeneity and the diversity of access networks, and various user applications with different QoS requirements pose new challenging on multi-mode mobile terminal (MT), particularly, performing the terminal, network and application context perception and designing optimal network selection algorithm are major issues for guaranteeing user seamless QoS support. In this paper, an adaptive MT platform conducting information perception and access network selection is designed and the functions of the planes and consisted modules in the platform are described. The platform-embedded algorithms, including information pre-processing, neural network based system modeling and network selection algorithm are proposed. The basic idea and the detail algorithm workflow are given.
