Abstract:
PURPOSE: An access control method and an apparatus thereof in a USN middleware are provided to supply a USN middleware access of an application to be supplied a service. CONSTITUTION: A role control unit(222) defines a plurality of sensor networks as a role unit. A verification unit(223) decides whether an authority in which the application uses the service or not when a service gets a request from an application. The verification unit decides an access whether or not one or more sensor network in which a role processing is allocated the service among a plurality of sensor networks. A register(221) manages the service with an API list format.
Abstract:
A unified data processing apparatus for processing a unified query to various sensor networks and a method thereof are provided to make data process efficient with respect to plural heterogeneous sensor networks which have different features and are physically separated from one another, and to access easily the sensor networks via one interface. A unified query parser(111) parses an inputted integrated query, and analyzes structure of the parsed unified query. A unified query execution plan generator(112) analyzes meaning of the parsed unified query and generates a unified query execution plan for processing the unified query. A unified query optimizer(113) optimizes a processing time of an execution plan generated by the unified query execution plan generator on the basis of query information and sensor network information. A unified query executer(114) subdivides the unified query execution plan by adjusting an execution sequence according to the optimized unified query execution plan, and transfers the unified query from an event processing unit, a temporary data processing unit or a continuity data processing unit according to the execution plan.
Abstract:
An incoming-call processing method while using a mobile RFID(Radio Frequency Identification) service and a wireless communication terminal where the method is realized are provided to properly process an incoming call according to each step of a mobile RFID service procedure, thereby removing a collision problem occurring during the incoming-call processing and the RFID service procedure and reducing the time required for processing the incoming call and mobile RFID service in the terminal. An RFID reader(220) obtains tag information through communication with an RFID tag. A controller(230) demands CS(Contents Server) location information to an ODS(Object Directory Server) based on the tag information, and demands contents information to a CS based on the tag information and the CS location information. A memory(240) stores the tag information. The controller(230) controls collision between a mobile RFID service action and an incoming-call processing action according to call receiving time while a mobile RFID service is performed.

Abstract:
A mobile RFID service apparatus for offering a user classification discriminatory service and a method thereof are provided to give discriminatory service and safe mobile RFID service through verification of communication security among nodes and authority of mobile RFID service, by setting security association(SA) among nodes for mobile RFID service using a diameter AAA(Authentication, Authorization and Accounting) protocol. In a mobile RFID service apparatus for offering a user classification discriminatory service, a policy server(13) provides determines QoS level of each user using a mobile RFID phone(10) and determines a policy among nodes about security. An AAA(Authentication, Authorization and Accounting) server(12) performs network access authentication and authority verification as to each user through a diameter message, authority verification for mobile RFID service, security association setting among nodes and distribution function, on the basis of the information of the policy server. A mobile RFDI agent(11) performs a diameter client role and a mobile RFID service agent role, according to the request of the mobile RFID phone mounting an RFID reader. A service server(15,16,17,18) searches URL of a server providing information related with an RFID code, and provides detail information and history information of an RFID tag attached object to the corresponding mobile RFID phone, according to the QoS level information of the corresponding mobile RFID phone user given from the mobile RFID agent.
