Abstract

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.

Claims

1. A wireless communication terminal capable of providing a mobile radio frequency identification (RFID) service, comprising:

an RFID reader configured to acquire tag information through communication with an RFID tag;

a controller configured to request an object directory server (ODS) for contents server (CS) position information based on the tag information transmitted from the RFID reader and request a contents server for service contents information based on the tag information and the CS position information transmitted from the object directory server; and

a terminal memory configured to store the tag information,

wherein the controller performs control to avoid collision between a reception call processing and a mobile RFID service processing according to when a call is received in the steps of the mobile RFID service processing.

2.
