UBIQUITOUS GATEWAY AND/OR GLOBAL QUERY MANAGER FOR QUERYING OBJECT IN MOBILE COMMUNICATION NETWORK

摘要

PROBLEM TO BE SOLVED: To save object search infrastructure construction costs in a mobile communication network. SOLUTION: The mobile communication network comprises a plurality of ubiquitous gateways 100. The ubiquitous gateway 100 comprises a first communication means 110 for communicating with the mobile communication network and a second communication means 120 for communicating with an object Ubiquitous Gateway or an object. The ubiquitous gateway 100 comprises an object cache 130 for temporarily storing an object record comprising an object record identification received from other ubiquitous gate way or object. The ubiquitous gateway 100 repetitively exchanges the object record with other ubiquitous gateways, and when an object query is received, reports the object record from the object cache 130 to a query origin.
