Radio Frequency Identification (RFID) technology is recently intensively investigated as an effective solution for the next generation communication services in business processes. In this paper we propose an RFID-based location tracking system for distributed offices based on Session Initiation Protocol (SIP). The proposed system is compatible with EPCglobal standard, but extension with SIP at application layer allows interoperability between various devices and platforms, which is not generally supported by the EPCglobal standard. In comparison with existing solutions the proposed system distributes RFID tag presence information to users through IMS (IP Multimedia Subsystem) presence enabler service. This enables real time monitoring of the observed office assets and their current presence status.
