MIDDLEWARE DEVICE FOR THREE-TIER UBIQUITOUS CITY SYSTEM

摘要

Disclosed is a ubiquitous city (u-city) exclusive middleware to provide services to a u-city. A middleware device performs a role corresponding to a brain of a human being by aggregating u-city information collected through wired and wireless converged and complex communication networks, analyzes the aggregated information, finds an optimal service based on reasoned current context information and a given command, and processes the found service to be executed. The u-city exclusive middleware performs various embedded functions by operating in a three-tier method through a u-city infrastructure and a u-city portal, and an operating method and executed functions of the middleware follows a method of an operating system of a typical computer system.
