Here, the specific area based on the subscriber or the specific group according to the present invention can be set without limitation to a small area center such as a building, an office, a school, a hospital, an apartment, etc. based on the mobile communication service subscriber or the business group.

The subscriber station 20 according to the present invention attaches an RFID tag as part of an RFID location tracking system for acquiring location information according to whether a user enters a location within a specific zone.

 Here, the RFID system is composed of middleware including a tag, a reader, a servant, an object name services (ONS), a product markup language (PML), and the like. to provide.

When the reader sends a radio wave to a tag, the tag gets energy from the received radio wave and is activated, and the activated tag carries its information and transmits it to the reader.

In this case, the tag is classified into a passive type and an active type according to a method of obtaining an energy source of radio waves transmitted by the tag.

The passive type obtains transmit energy from radio waves received from the reader, the active type obtains transmit energy from a separate battery, and the reader transmits the collected information to the center through the network.

The reader sends the read tag information to the servant server to check the PML position where the thing information exists in the ONS, and obtain specific information of the thing from the PML server.

Here, the servant server filters the tag information received from the device that recognizes the RFID tag information as defined in the RFID International Standard (ie, removes the duplicate tag information) and performs an ONS (Object Name Services) server. In conjunction with this, the PML (Physical Markup Language) server information on the tag information is acquired to obtain detailed information according to the tag information from the PML server.

In addition, the PML server is a system that stores and stores the information collected by the servant server, that is, the product name, the current state, the location, etc. in the PML form and provides data. In particular, it is possible to provide a function of storing and managing history information recognized through static information of the object and RFID technology, and representative PML servers include EPC IS (EPC Information Service) and PML server.

In addition to the basic function, the servant server 30 defined in the present invention filters the received tag information separately and determines the home location information server 50 by using a mapping table related to the corresponding tag information. Send information to

When the subscriber terminal combining the RFID tag enters the corresponding area, the RFID tag recognition system detects whether the subscriber terminal enters a specific zone, and the servant server 30 filters the RFID tag ID information to perform IMSI (International). Location information server by configuring location-related information of the terminal 20 such as mobile station identity (MSID), mobile station identification (MIN) information including mobile identification number (MIN), and predefined special zone information (SZI) Transfer to 50.

At this time, the message transmission and reception between the servant server 30 located in a specific area and the location information server 50 in the mobile communication network can communicate using various protocols such as HTTP, SMPP, SIP, and XMPP. In the wired and wireless IP network can be used and there is no limitation in the present invention in the communication and connection method.

Here, the International Mobile Station Identity (IMSI) is based on 3GPP TS 23.003 definition, and is composed of Mobile Country Code (MCC), Mobile Network Code (MCC), and Mobile Subscriber Identification Number (MSIN), where MCC is the mobile subscriber's country. MNC is a mobile network code of a mobile communication provider, MSIN is an identification number of a mobile subscriber, and all mobile subscribers have a unique IMSI number.
