1. A User Equipment (UE) for constructing a graded resource model for peripheral network equipments around a user in a ubiquitous (U-) network by dividing UE-peripheral equipments into U-nodes and U-gadgets according to capabilities and characteristics in use to form a hierarchical structure in organization of ubiquitous equipments, the UE comprising a data transferring module and a functioning module, wherein the data transferring module is configured to perform data interaction with a ubiquitous node (U-node) via a protocol layer for U-node network connectivity and a protocol layer for wide-area connectivity using a Transfer Control Protocol (TCP)/User Datagram Protocol (UDP), and to receive a service request of the user comprising information on a requested service and information on the user; and the functioning module is configured to: determine a UE capability required by the service by analyzing the service request; determine required U-nodes in a peripheral network environment according to the UE capability required by the service; aggregate the required U-nodes into a virtual UE; integrate service data provided by the virtual UE, and present the integrated data to the user via a service component comprising input and output equipments.
