Abstract:
A system for tracking location of person having signal transmitter includes at least one receiver for receiving unique ID signal transmitted by signal transmitter that transmits ID signal uniquely determined for respective mobile signal transmitter at at least one predetermined period. The receiver receives unique ID signal near circumference of the person having signal transmitter spaced apart from the receiver by given distance, and stores the received unique ID signal in ID store unit. The receiver, when search request for specific ID is received from external server, searches for the requested ID in ID store unit and transmits transmission information including ID corresponding to requested ID to external server. The person, such as abducted person, has only small signal transmitter, and thus the current location of the abducted person and path along which the abducted person moved can be tracked using the signal continually transmitted by the signal transmitter.
Abstract:
PURPOSE: A terminal and communication system using an RF4CE are provided to reduce a cost by directly enabling a terminal using a RF4CE communication network to communicate such as SMS without passing through a separate service business owner. CONSTITUTION: A terminal(10) is includes in a RF4CE communication module. A gateway(20) stores inherent ID information and ID information for identification of a plurality of terminal located in a constant area. The gateway periodically transmits the stored table to an external side. A central control server(40) is connected through at least one gateway and a communication network.

Abstract:
PURPOSE: A system for tracking a kidnapped hostage tracking system, a transmitter used in the same, a sensor network gateway and a method of tracking a kidnapped hostage are provided to supply a safety service to protect safety of sons or daughters using location and situation information of the sons or daughters through a sensor network service using a broadcasting communication network. CONSTITUTION: A system for tracking a location of a user using a transmitter includes a plurality of transmitters(20). A receiver receives an intrinsic ID signal transmitted from the transmitter. The receiver receives the intrinsic ID signal transmitted from the transmitter at a location around a user who is apart from a user having the transmitter. And the receiver stores the signal in an ID storage unit(22). If a search request about a specific ID is received from an external server, an ID to be requested to be searched is searched in the ID storage unit. Transmission information including an ID corresponding to the requested ID is transmitted to the external server.
Abstract:
PURPOSE: A mobile communication terminal and a communication method thereof in a sensor network system based on IP are provided to make a communication between an IP service provider and the mobile terminal for an IP service. CONSTITUTION: An SIM(Subscriber ID Module) card(210) stores information about a user for data communications through cellular network. A nsor network smart chip(220) comprises a protocol stack operationally connected through a connection interface with the SIM card. The protocol stack comprises a higher layer according to the IP-based sensor network standard for the data communications through the sensor network of an IP(Internet Protocol) base. A wireless interface module is operationally connected to the SIM card and smart chip. The sensor network of the cellular network and IP-based and wireless communication is proceed.
