TDMA CONTROL METHOD OF MOBILE RFID READER VIA MOBILE PHONE BASE STATION

摘要

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).
