A New Context Awareness Scheme for Multi-mode Mobile Terminals in Mobile Internet

Mobile Internet should provide pervasive services anywhere, anytime, and in numerous ways. Therefore, it is demanded that users could visit Internet services through any kind of radio access technology. Context awareness for multimode mobile terminals (MMT) in Mobile Internet is very important in next generation wireless mobile communications. It is the foundation of network co-operation and seamless access for user services. In this paper, a new context awareness scheme for MMT is proposed. And monitoring models for context awareness is also raised. The scheme is based on mobile agent technology, which is beneficial for saving monitoring cost of MMT. Furthermore, a mechanism of radio access network (RAN) monitoring is presented. This mechanism is on the basis of cognitive radio and reconfiguration technologies. It not only improves the intelligence of MMT but also can be widely applied in heterogeneous radio environment. Signal detecting method is designed, and the process of this mechanism is also given. Finally, in the context composed of 4 kinds of overlapped RANs, the availability of this scheme is proved by simulation results.
