The present invention relates to a method and a system for locating a terminal using an AP of a WLAN in a WiBro network interworking with a WLAN. More specifically, when a time delay is added to a wireless signal of an AP or a flag is transmitted to a WiBro network, the WiBro network transmits a wireless signal by checking a time delay value of a wireless signal or a flag value included in the wireless signal. The present invention relates to a method and a system for identifying a location of a terminal using an AP of a WLAN in a WiBro network interoperating with a WLAN network capable of identifying an AP and obtaining location information of a location where the AP is installed.

As computer, electronic, and communication technologies have made rapid progress, various wireless communication services using wireless networks have been provided. Accordingly, a service provided by a mobile communication system using a wireless communication network is developing not only a voice service but also a multimedia communication service for transmitting data such as circuit data, packet data, and the like. Recently, the third generation mobile communication system, IMT-2000 (International Mobile Telecommunication 2000) (for example, Code Division Multiple Access (CDMA) 2000 1X, 3X, EV-DO, WideBand CDMA (WCDMA), etc.) has been commercialized. .

However, the existing mobile communication system has a limitation in providing high-speed wireless Internet due to the high base station construction cost and the high usage rate of the wireless internet, and the small size of the mobile communication terminal, which restricts the available contents. . Therefore, WiBro (Wireless Broadband Internet), a high-speed portable Internet service that guarantees portability and mobility and can use high-speed wireless Internet service at a low price, has emerged.

WiBro service uses various types of portable communication terminals such as laptops, PDAs, and handheld PCs to access various information and contents through internet access in indoor and outdoor stationary environments and mobile environments of walking speed and low to medium speeds It is a service. WiBro system uses the 2.3 GHz frequency band and provides mobility of 60 km / h per hour. The downlink transmission rate is 24.8 Mbps, but the uplink transmission rate is 5.2 Mbps. System. In addition, the WiBro system uses a time division duplex (TDD) in a duplex method and an orthogonal frequency division multiple access (OFDMA) / time division in a multiple access (TDMA) method in order to effectively use an allocated frequency spectrum. Multiple Access).

Here, the TDD scheme is a bidirectional transmission scheme in which downlinks and uplinks are alternately assigned in time in the same frequency band. The TDD scheme has a high transmission efficiency and is suitable for asymmetric or bursty application transmission due to dynamic allocation of timeslots. The OFDMA / TDMA scheme is a multi-access scheme similar to TDMA, in which all subcarriers spread over the entire bandwidth are allocated to one user for a certain period of time and then assigned to another user for the next predetermined period of time, thereby improving transmission rate per bandwidth and multipathing. ) It has the property to prevent interference.

On the other hand, various wireless Internet services are being activated with the development of wireless Internet technology, and in particular, LBS (Location Based Services) has gained much attention due to its wide availability and convenience. Location-based service refers to a communication service that locates a mobile communication terminal such as a mobile phone, a personal digital assistant (PDA), a notebook PC, and provides additional information related to the identified location. In order to use the location-based service, it is necessary to determine the location of the mobile communication terminal. For this purpose, a handset using a network-based method or a global positioning system (GPS) signal that distinguishes a base station using a base station reception signal is used. Handset-based method can be used.

However, since the location of the mobile communication terminal cannot be determined by a handset based method using GPS signals in a place where satellites are not visible (such as in a tunnel, inside a building, or in a basement of a building), the mobile terminal uses a network based method. The location of the base station serving the area where the communication terminal is located will be identified.

WiBro network basically has a smaller range than the existing mobile communication network and installs RAS (Radio Access Station) which is the base station of WiBro system rather than using a repeater to cover many areas of the city center like the existing network. Will be. Therefore, in the WiBro network, more base stations will be constructed to cover a specific area than the existing network. Since the coverage of the base station is small, identifying the base station in a network-based manner may allow a position measurement having a smaller error range than that of the existing network. will be.

However, even if the error range of the location measurement is reduced, when the mobile communication terminal is located inside the building, there is a problem in which the mobile communication terminal is located in which building within the base station coverage, and on which floor of the building.

In order to solve this problem, the present invention, if a time delay is added to the wireless signal of the AP of the wireless LAN network interworking with the WiBro network or transmitted to the WiBro network including a flag, the time delay value or wireless of the wireless signal in the WiBro network Identifying the AP that transmitted the wireless signal by checking the flag value included in the signal, the terminal of the terminal using the AP of the wireless LAN in the WiBro network interworking with the wireless LAN network that can obtain the location information of the location where the AP is installed It is an object to provide a positioning method and system.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals have the same reference numerals as much as possible even if displayed on different drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Wireless Local Area Network (WLAN) service is a wireless data service that combines low-cost, high-quality transmission technology in wired communication with convenient mobility in wireless communication as part of wired and wireless integration services. The wireless LAN service installs a wireless access point (AP) at the end of a subscriber network such as an Asymmetric Digital Subscriber Line (ADSL), a Very High Data Rate Digital Subscriber Line (VDSL), and an E1, and provides wireless access within the coverage of the AP.

IEEE 802.11a is a standard specification of 54 Mbps, uses a frequency band of 5 GHz, and uses an OFDM scheme as a frequency spreading scheme. IEEE 802.11b is an 11 Mbps standard that uses the 2.4 GHz frequency band and uses DSSS (Direct Sequence Spread Spectrum) as the frequency spreading method.

Wireless LAN Service Although it is commercially connected to wired subscriber networks such as ADSL and VDSL, the wireless LAN service can provide wireless Internet services by interworking with wireless subscriber networks such as WiBro networks. Of course, since the WLAN signal and the WiBro signal are different in technology such as frequency band and frequency spreading method, in order to interwork the WiBro network and the WLAN network, after converting the WiBro signal to the WLAN signal to be interworked, Will be sent.

Since the AP of the WLAN can be installed and used in the radio shadow area, when the WiBro network and the WLAN network are interworked, the wireless Internet service provided by the WiBro network can be provided to the terminal located in the radio shadow area through the AP. Therefore, by using the AP of the wireless LAN, the location of the terminal in the radio shadow area in the WiBro network can be provided to provide a location-based service, and a method of confirming the location of the terminal using the AP will be described below.

1 is a block diagram illustrating a WiBro system interworking with a WLAN network according to an embodiment of the present invention.

In addition, the PSS 100 may be equipped with a WLAN network adapter to use a wireless Internet service within the coverage of the AP 110. Accordingly, the PSS 100 is a terminal equipped with a multimode-multiband (MM-MB) function capable of transmitting and receiving a WiBro signal and a wireless LAN signal. A personal digital assistant (PDA), a hand-held PC, and a cellular device are used. It may include a phone, a mobile broadband system (MBS) phone and the like.

The AP 110 transmits data received from the RAS 120 as a base station of the WLAN network to the PSS 100 located within the coverage of the AP 110 wirelessly. The AP 110 may have a function of processing a WiBro signal. In this case, the AP 110 may receive a WiBro signal directly from the RAS 120, convert the WiBro signal into a WLAN signal, and then transmit the WiBro signal to the PSS 100. In addition, a relay device for relaying a signal between the RAS 120 and the AP 110 may be installed. In this case, the WiBro signal transmitted from the RAS 120 is changed from the relay device to the WLAN signal to the AP 110. The AP 110 transmits the received WLAN signal to the PSS 100.

The AP 110 may be installed in a radio shading area of a building, a basement of a building, a tunnel, and the like, and may install a plurality of APs 110 in the entire radio shading area to provide a wireless data service.

The IP network 140 connects the ACR 130, the location management server 150, the PDSN 160, the HA 170, the AAA 180, and the like to provide a path for exchanging data.

The location management server 150 identifies the corresponding AP 110 using the time delay value of the wireless signal of the AP 110 or the flag value included in the wireless signal and generates location information of the PSS 100. The location management server 150 includes a location information database (not shown). The location information database has a time delay value or a flag value of a radio signal transmitted from the AP 110 in which the building address, name, It is stored in correspondence with location information including floors or representative stores. Therefore, the location management server 150 obtains the location information of the place where the AP is installed by inquiring the time delay value or the flag value of the radio signal transmitted from the AP 110 in the location information database.

The location management server 150 transmits the obtained location information to a wireless Internet service server such as the Internet 190 that provides location-based services, and the wireless Internet service server may provide various locations based on the location information of the AP 110. The base service is provided to the PSS 100.

The PDSN 160 manages a session to service wireless data as packet data, receives packet data from an external packet data server such as the Internet 190 through the IP network 140, and delivers the packet data to the ACR 130. . In addition, it manages the location information data of the mobile communication terminal, including the PSS (100).

The positioning device distinguishes the representative AP 110 of each floor and the AP 110 of each floor connected to the representative AP 110 of the building, and the respective APs 110 in the building so that the WiBro network can recognize the specific AP 110. A time delay may be added or a flag value may be added to the wireless signal generated by the AP 110.

3 is an exemplary view showing the configuration of an AP installed inside a small building, Figure 4 is an exemplary view showing the configuration of an AP installed inside a large building.

As shown in FIG. 5, the AP 110 adds a certain time delay to a wireless signal or includes a specific flag so that the specific AP that transmits the wireless signal can be distinguished from the WiBro network (S500). Of course, the time delay value or the flag value sets different values for each AP 110 to distinguish each AP 110. The wireless signal including the time delay or the flag is transmitted to the location management server 150 through the RAS 120, the ACR 130, and the IP network 140 of the WiBro network (S502).

The location management server 150 checks a time delay value of the radio signal or a flag value included in the radio signal and searches for information of the AP 110 corresponding to the time delay value or flag value in the location information database (S504). . The location management server 150 identifies the specific AP 110 that has transmitted the radio signal as a result of the search (S506), and identifies a building address, name, floor, or a specific location of the floor where the specific AP 110 is installed.
