Abstract: A communication method for the RFID is provided to obtain a response including desired data without a separate command from an RFID reader. In case a received random value does not collide with the identifier of the other tag communicating with an RFID(Radio Frequency Identification) reader, the same value as the received random value is allocated as the identifier of an RFID tag(S402,S403). A command message including a response format and the allocated identifier is transmitted(S404). A response message to the command message is received from the RFID tag(S405). Based on the response format, sensor data which is positioned next to the UII(User Interface Integration) of the response message is extracted from the received response message(S406).

Abstract: A mobile RFID reader and an RFID communication method using shared system clock are provided to implement a technology for preventing a collision between readers in a mobile multi-reader environment by using shared clock for RFID. A mobile communications part(610) produces the clock synchronization signal in a specific pattern of the down-link frame broadcasting from the base station. An RFID reader unit(650) shares system clock with other mobile RFID readers through a system clock is synchronized with the clock synchronization signal. An interface unit(630) delivers the clock synchronization signal to the RFID reader unit from the mobile communication unit. A specific pattern of a frame includes the information informing a beginning of the specific burst or a beginning of a frame of a down-link frame. After sharing system clock with the other mobile RFID reader, the RFID reader unit generates a time slot for the RFID communication with the tag based on the clock synchronization signal.

Abstract: A communication method for the RFID is provided to make a tag immediately transmit additional data through a response message by transmitting a command message including a command code, the kind of additional data and an identifier for distinguishing the response format and tag. A random value issued as the identifier of a tag is transmitted to an RFID(Radio Frequency Identification) reader(S501). A command message is received from the RFID reader(S502). The state of the tag is changed into an ACK mode(S504). Based on the response format of the received command message, additional data is inserted into a response message(S505). The response message is transmitted to the RFID reader(S506).

Abstract: A method and a mobile RFID reader which controls TDMA of a mobile RFID reader through a mobile base station are provided to prevent interference between readers by occupying a channel during a time slot and frequency allocated in the mobile RFID reader. A mobile RFID(Radio Frequency Identification) reader requests a channel for RFID communications with a tag as a base station through the uplink channel according to the protocol of the mobile network(S610). The base station assigns the channel information of the transmission channel and transmit window to the mobile RFID reader through the downlink channel according to the protocol of the mobile network(S630). The mobile RFID reader performs the tag selected according to the channel information in the allocated frequency channel for the designated time slot(S650). The mobile RFID reader transmits the history information collected for the inventory round to the base station after the inventory round termination(S670).
