It is a flowchart showing the site tag processing method of the site tag name server according to the present invention.

In the personal information service system using the wireless terminal according to the present invention, the site tag transmitter 11 for transmitting a wireless site tag signal corresponding to an address of a site that can provide its installation location related information. The wireless terminal 10 receives the site tag transmitted from the site tag transmitter 11 and transmits the received site tag to the corresponding server, and the web site or the swap site or database corresponding to the site tag received from the wireless terminal 10. And a site tag server 12 for requesting data transmission to the web site server or the swap site server or database so that information is transmitted to the wireless terminal 10.

In this case, the site tag transmitter 11 is installed at a tourist spot, exhibition hall, museum, or a specific area information board installation place, and transmits an infrared data association (IrDA) infrared transmission port, RF (Radio Frequency) to transmit a site tag signal of a wireless type within a predetermined distance. At least one or more of the module or Bluetooth.

Here, IrDA refers to a protocol for wirelessly transmitting and receiving information between two terminals using infrared rays. Initially it was an international organization that established standards for infrared communications, but now even products using protocols or IrDA protocols are collectively called IrDA. Currently, protocols up to 4Mbps are established, and the average PDA supports 115Kbps.

In addition, the wireless terminal 10 includes a mobile phone, a PDA, a web pad, and the like, and when the site tag signal is received, the site tag signal 12 and the site tag server 12 recognize the self. A program for transmitting predetermined data is built in.

In addition, the site tag server 12 has a built-in database of site addresses corresponding to the site tag signal transmitted from each site tag transmitter 11.

The configuration of the present invention described above uses a wireless LAN or a wireless communication network of the CDMA 2000 IX system. First, the wireless LAN is the same as the general wired network configuration method and protocol, but differs in that only the wired portion between the server and the terminal is configured wirelessly. . The WLAN supports speeds up to 11Mbps, and the standard is currently IEEE 802.11b (Direct Seguence Spread Spectrum). Since the frequency band is 2.4GHz and usually supports the Roaming function, continuous use is possible even when moving while using the WLAN. The network can be configured from several hundreds to hundreds of terminals according to the Access Point within the range of 30 to 120 m indoors and hundreds of meters outdoors. By using an antenna, it is possible to configure a network up to a terminal within a few Km range.

The CDMA 2000 1X (IS-95C) generally refers to a protocol between a terminal (MS) and a base station controller (BSC) that controls a base station. However, IS-95C is a more comprehensive concept. It is an evolution of the existing network (IS-95A / B) that is currently being serviced as a whole system over the wireless section. GHz band) refers to a technology that can support up to 144kbps, the initial data rate of IMT-2000.

In addition, Site Tag is a wireless signal that can accurately and easily transmit the address of a site without the need for complicated data communication hardware and software. It can assign unique site tag values to specific web sites, swap sites, and data. Therefore, the site tag designated for each site is stored in each site tag transmitter 11 and is set to be transmitted within a range corresponding to the transmission medium (IrDA infrared transmission port / RF module / Bluetooth).

The custom information service method of the present invention configured as described above will be described with reference to FIGS. 2 and 3.

When the user carrying the wireless terminal 10 approaches the site tag transmitter 11 within a predetermined distance (site tag transmitter transmission range), the site tag signal transmitted by the site tag transmitter 11 is transmitted to the wireless terminal. 10 will receive.

Subsequently, as shown in FIG. 2, when a predetermined site pick signal is received, another input is blocked (S21), and it is determined whether the received site pick signal is valid (S22).

At this time, the validity of the site tag signal may be determined by an electric noise.

Subsequently, if the site select signal is valid, the determination result (S22) determines whether it is the same as the previously received site select signal (S23).

At this time, since the wireless terminal 10 stores the received site tag as a log file, the wireless terminal 10 performs the determination step S23 by comparing the previously stored previous site tag with the currently received site tag. This is to prevent the site tag server 12 from reconnecting to the same site if the user continues to be in the same location and transmits the same site tag.

In operation S23, if the currently received site tag is not the same as the previously received site tag, it is transmitted to the site tag server 12 through the aforementioned wireless communication network (WLAN / CDMA 2000 IX) (S24). .

At this time, together with the site tag, information that can recognize the site terminal server 12 that has transmitted the site tag is transmitted together.

Meanwhile, as shown in FIG. 3, the site tag server 12 receives the received site tag (S31), compares the database, that is, the site tag / IP address table (S32), and the IP address corresponding to the site tag. That is, it is determined whether a web site or a swap site address exists (S33).

As a result of the determination (S33), if the corresponding IP address exists, the corresponding web page or swap page information is transmitted to a web server or a swap server or a database corresponding to the IP address through the aforementioned wireless communication network (Wireless LAN / CDMA 2000 IX). Request to transmit to the wireless terminal 10 (S34).

On the other hand, if the determination result (S33), the corresponding IP address does not exist, and transmits an error message indicating that there is no web page or the swap page to the wireless terminal 10 through the above-described wireless communication network (Wireless LAN / CDMA 2000 IX) (S35).

Accordingly, the web server or the swap server or the database transmits its page information to the corresponding wireless terminal 10 according to the request of the site tag server 12 through the above-described wireless communication network (WLAN / CDMA 2000 IX).

The personalized information service system using the wireless terminal of the present invention provides easy access to specific information only by accessing a specific place without the need to operate a complicated wireless terminal, thereby providing tourism, viewing, local information, and other wireless terminal services to the user. There is an effect of providing a convenience that can easily use a wireless service in a place.
