摘要： Provided is a method for estimating the number of tags in a slotted Aloha-based RFID system, which can estimate the number of tags through a new statistical average scheme using the number of slots, the measured number of empty slots, and the measured number of ID slots. The estimating method includes the steps of: a) setting the number (N) of slots, the measured number (c0) of empty slots, and the measured number (c1) of ID slots as parameters; and estimating the number (n) of the tags by substituting the set values into n=(N−1)/(c0/c1).

摘要： Provided are a method for processing reception calls during mobile RFID service processing, and a wireless terminal employing the method. The terminal provides mobile RFID service by receiving tag information from the RFID reader, requesting the object directory server for CS position information based on the tag information, requesting service contents based on the tag information and CS position information. The present invention prevents collision between reception call processing and mobile RFID service processing in the wireless terminal by processing reception call appropriately to each duration of mobile RFID service processing. For example, when a call is received before read command is transmitted to the RFID reader, the RFID reader is turned off and the reception call is processed. When a call is received before CS position information is requested, the CS position information is requested after the reception call is processed.
