Research on Virtual Terminal Technology Based on Context-aware in Ubiquitous Network
Xiaorong Zhu · Computer Technology and Development · 2013
In ubiquitous network environment,the service provider must adaptively change as the network and terminal's condition,and the user's preference change.Therefore,a context-aware function of virtual terminal is described,which could provide essential information support for ubiquitously various services.A middleware based on context-aware which is suitable for virtual terminal systems is provided,which could Abstract feature parameters of terminal environment for all kinds of service scenarios,and form retrievable and formalized contexts.Furthermore,a service model based on the context-aware is given.Finally,the proposed Abstract definition method and service model are verified by a typical multimedia service scenario.The results show that the method can extract the context required by ubiquitously various service.Based on the model,service platform can adapt to heterogeneous terminal environments dynamically,and provide various and best experience services for users.
