The present invention relates to a method for supporting wireless access AP, and more particularly, location information of a wireless access AP within a service coverage of a mobile communication base station, and location information of a terminal including a wireless access modem, a mobile communication modem, and a GPS module. The present invention relates to a method for supporting efficient discovery of a wireless access AP based on the.

Recently, the communication environment is developing with the integration trend of wired and wireless, communication and broadcasting. In particular, a combined service that connects a mobile communication network of a WLAN (Wireless LAN) / WiBro (WiBro) and the like is a representative wire / wireless complex service. WLAN / WiBro has the disadvantage of narrow service coverage while guaranteeing high data rates at low equipment prices. Therefore, services using WLAN / WiBro are suitable for high-speed data transmission in urban areas or in crowded areas (eg, airports, shopping malls, etc.). On the other hand, the mobile communication system has the advantage of having a nationwide service coverage while supporting the medium / low data transmission speed. Therefore, combining these two services provides high-speed data service through WLAN / WiBro in stationary or pedestrian environments such as urban areas, and mobile communication networks in other areas or high-speed mobile environments to ensure service continuity. can do.

In order to provide a combined service of a high-speed data system and a mobile communication network, a terminal technology capable of simultaneously accessing a WLAN / WiBro and a mobile communication network is essential. A terminal equipped with both a wireless access modem and a mobile communication modem centering on a PDA OnePhone is being released to enable integrated wireless and wired and wireless services, and WiBro / WiMax and mobile communication devices are expected to be released in the future. Users can freely select and use mobile communication networks and various wireless access networks using these terminals. However, since mobile networks currently have almost nationwide coverage, they can be accessed from anywhere at any time.However, WLAN / WiBro will have relatively limited service coverage per AP, and will be installed or installed in urban centers. Therefore, it is not possible to know exactly whether WLAN / WiBro service is available in the area where the user is currently located. Therefore, the user has no choice but to determine whether the WLAN / WiBro connection is possible by directly attempting to search for a wireless access by using a combined terminal in a downtown area, etc., and thus, users have a low usage rate of the combined service.

As a solution to this problem, there is a method in which the UE periodically searches for a WLAN / WiBro network. Mobile communication and WLAN / WiBro combined terminal generally monitors messages from the mobile communication network periodically for voice call terminating service. During this period, the WLAN / WiBro network search is periodically attempted and the result is displayed on the terminal monitor to inform the user whether the WLAN / WiBro connection is possible. However, in this case, since both the mobile communication modem and the WLAN / WiBro modem of the terminal should be in the ON state, the battery consumption of the terminal increases, which is inefficient. In addition, considering the fact that the service coverage of WLAN / WiBro is relatively extremely small compared to the mobile communication service coverage, the degree of inefficiency becomes very large.

Other objects, specific advantages and novel features of the present invention will become more apparent from the following detailed description and the preferred embodiments associated with the accompanying drawings. Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. A combined terminal means a mobile communication terminal including a wireless connection modem and a mobile communication modem, and api refers to a wireless access device (Access). Point).

1 is a flowchart of a method for supporting AP search of a combined terminal using a location-based service according to the present invention.

In step S101, the mobile communication base station 102 receives the AP location information and the AP system information. When the AP 100 is located within the service coverage of the mobile communication base station 102, the AP location information is the service coverage of the mobile communication base station 102 in which the AP 100 is currently serving the area where the combined terminal 104 is located. Within The AP system information indicates whether a system currently supported by the AP 100 is a service system such as WLAN (Wireless LAN), WiBro (WiBro), WiMax (WiMAX), OnePhone (OnePhone), and so on. Used to find available service systems. Here, the AP system information may include information on the service radius of the AP. The information on the service radius of the AP is about tens of meters, which is smaller than the service coverage of the mobile communication base station 102, so how far the combined terminal 104 is located from the AP 100. It is used to determine whether the combined terminal 104 is located within the service coverage of the AP 100 by measuring the.

How the mobile communication base station 102 receives the AP location information and the AP system information is as follows. First, after the AP 100 is installed by the AP system installation service provider, the AP system installation service provider directly informs the mobile communication system operator of the AP location information and the AP system information and transmits the information to the mobile communication base station. By registering with 102, the mobile communication base station 102 can receive.

Secondly, the AP 100 may be equipped with a mobile communication module. When the mounted mobile communication module is registered with the mobile communication base station 102, the mobile communication module may transmit the AP location information and the AP system information to the mobile communication base station 102. When the mobile communication base station 102 receives a signal from a mobile communication module mounted on the AP 100, this means that the AP 100 is currently within service coverage of the mobile communication base station 102. In addition, since the mobile communication base station 102 periodically communicates with the mobile communication module installed in the AP 100, the mobile communication module may inform information about whether the AP 100 is in operation. By transmitting information by dividing the case in which the AP 100 is operating without failure and the case in which the AP 100 is not operable due to a breakdown, the mobile communication base station 102 periodically transmits the information to the position information of the operable AP 100. Can be updated.

Here, the method for the mobile communication base station 102 to receive the AP location information of the AP 100 is as follows. First is a network-based technology, it is possible to obtain location information using a mobile communication base station and a wireless network. The position of the detailed mobile communication module may be detected using the radio wave intensity information of the signals received from the plurality of mobile communication base stations 102 around the AP 100 in which the mobile communication module is mounted. At this time, in order to know the distance between the mobile communication base station 102 and the mobile communication module, the propagation time of the signal is calculated by a correlator and a delay lock loop (DLL). It is possible. In the CDMA communication method, a PN (Pseudo-random Noise) code for each mobile communication base station 102 may be signaled to determine the distance from each mobile communication base station 102 to the mobile communication module. By calculating the distance from the three or more mobile communication base station 102 at the same time, it is possible to determine the two-dimensional position of the mobile communication module by triangulation.

Referring to FIG. 3A, the time of the mobile communication base station 300, 302, 304 is observed when a signal sent from each mobile communication base station 300, 302, 304 is transmitted to the mobile communication module 310. do. At this time, the time synchronization between the mobile communication base stations 300, 302, 304 is performed using a satellite clock. When the difference in the transmission time of the signal sent from each of the mobile communication base stations 300, 302, and 304 is converted into a difference in distance, the hyperbolic line focuses on the mobile communication base station # 1 300 and the mobile communication base station # 2 302. There is a mobile communication module 310. In addition, the mobile communication module 310 exists on a hyperbola that focuses on the mobile communication base station # 1 300 and the mobile communication base station # 3 304. The mobile communication module 310 is positioned above the intersections of the hyperbolas. In addition, by forcibly transmitting a signal to a plurality of mobile communication base stations (300, 302, 304) time-synchronized in the mobile communication module 310, the mobile communication module 310 and the mobile communication base station (300, 302, 304) By knowing the distance and finding the intersections of the circles, the position of the mobile communication module 310 may be determined.

Second, as a handset-based technology, a GPS chip may be embedded in a mobile communication module mounted on the AP 100. Using GPS technology, satellite signals are analyzed using 24 satellites (actually 27, including 3 supplementary satellites) to obtain the three-dimensional position of the GPS chip regardless of location and time. Because the device is intended for military use, the location accuracy is limited to about 100m, but due to the elimination of intentional errors included in the satellite signal, the location accuracy is very accurate to around 5m.

Referring to FIG. 3B, a mobile communication module incorporating a GPS chip receives a signal from each satellite and transmits the received signal to a mobile communication base station. This satellite signal can be used by the mobile communication base station to determine the location information where the AP is located.

Third, as a hybrid technology, location information can be obtained by combining a network-based technology and a handset-based technology. In addition, the method for acquiring the location information of the AP is not limited to the above embodiments, and many modifications are possible by those skilled in the art within the spirit of the present invention.

In step S102 of FIG. 1, the combined terminal 104 requests the AP location information and the like from the mobile communication base station 102 according to the selection of the holder of the combined terminal 104. Instead of periodically transmitting the AP location information and the AP system information from the mobile communication base station 102 to the combining terminal 104, the holder of the combining terminal 104 may want to know the location and support system of the AP 100 at the current location. At the time, the mobile communication base station 102 requests transmission of the AP location information and the AP system information by selecting a shortcut button of the combined terminal 104 or a specific menu. In step S103, the mobile communication base station 102 transmits the AP location information and the AP system information to the combined terminal 104.

In step S104, the coupling terminal 104 determines whether the coupling terminal 104 is within the service coverage of the AP 100 using the AP location information and the location information of the coupling terminal 104.

Here, the location information of the coupling terminal 104 can be obtained by the following method. First, by processing the GPS satellite signal received through the GPS receiver module included in the coupling terminal 104 in the coupling terminal 104 to obtain the terminal position information represented by the coordinate information of the coupling terminal 104 typically can do. The combining terminal 104 converts the received GPS satellite signal into terminal location information using a pre-stored location information acquisition process and stores it in the memory. Thereafter, when the comparison with the AP location information is required, the stored terminal location information can be utilized. Secondly, the GPS satellite signal received through the GPS receiver module included in the combined terminal 104 is transmitted to the mobile communication base station 102, and the terminal position information is calculated by processing the signal in the mobile communication base station 102. This may be transmitted back to the coupling terminal 104. In the mobile communication base station 102, there is a device including a process capable of processing GPS satellite signals, so that the combined terminal 104 can convert the GPS satellite signals received and transmitted from the satellites into terminal location information.

As a result of the determination, when the coupling terminal 104 is within the service coverage of the AP 100, the AP location information and the AP system information are displayed on the coupling terminal 104. The holder of the combined terminal 104 sees the information displayed on the combined terminal 104, and when the combined terminal 104 is within the service coverage of the AP 100, the modem for wireless connection is turned on to transmit high-speed data. You can get In addition, it may be checked at this time whether the system is supported by the coupling terminal 104 possessing the AP system information.

Here, the AP location information may be coordinate information. It may be coordinates indicating longitude and latitude using an orientation, and may be coordinates for specifying a location on an electronic map. In addition, the coordinate information may be used to obtain information such as a name or address of a place or a building in which the corresponding AP 100 is located on the electronic map, and may be transmitted to the coupling terminal 104.

2 is a conceptual diagram of service coverage of a mobile communication base station and an AP according to an exemplary embodiment of the present invention. Referring to FIG. 2, if there is an AP 220 in a specific region, the service coverage of the mobile communication base station 210 includes the service coverage of the AP 220. In addition, there is a case where there is no API 220 in the service coverage of a specific mobile communication base station 210, and in reality, the latter case is much more. Therefore, continuously turning on the modem for wireless connection within the service coverage of the mobile communication base station 210 in which the api 220 does not exist has a great effect on the power consumption of the combined terminal 104. How to prevent this is as follows.

When the holder of the combined terminal 104 is in the position 202, the combined terminal 104 requests the AP location information and the like to the mobile communication base station 210. In response, the mobile communication base station 210 transmits the AP location information and the AP system information received from the AP 220 to the combined terminal 104. The coupling terminal 104 receiving the information compares the position information of the coupling terminal 104 and the AP position information measured using the GPS receiving module. As a result of the comparison, since the distance between the position 202 of the coupling terminal 104 and the position of the AP 220 is larger than the service radius of the AP 220, it is determined that the coupling terminal 104 is outside the service coverage of the AP 220. do. Thus, the holder of the combining terminal 104 recognizes that it is not within the service coverage of the AP 220 by the indication of the combining terminal 104 and does not operate the wireless connection modem.

When the holder of the coupling terminal 104 is located at the position 204, the distance between the position of the api 220 and the position 204 of the coupling terminal 104 according to the api position information requested and received at the position 202 is api. Since it is smaller than the service radius of 220, the coupling terminal 104 determines that it is within the service coverage of the ap 220. Accordingly, the holder of the combined terminal 104 may recognize that the service coverage of the AP 220 is within the service coverage of the combined terminal 104 and operate a wireless connection modem to perform high-speed data transmission.

In the present invention, the API system may be as follows. First, it may be a WLAN system. WLAN is an abbreviation of Wireless LAN, and is called a wireless LAN. It refers to a local area network using radio waves or infrared transmission. It's also called Wi-fi in the sense that it makes the wireless network as convenient as hi-fi audio. Wireless LAN also cannot use the Internet without a base station relaying radio waves wirelessly. Hotspot refers to a wireless LAN base station that relays radio waves installed to solve this problem. In order to install a hotspot, there must be an AP acting as a base station, which transmits a signal from a wireless LAN card installed in a notebook computer or a PDA (portable personal digital assistant) to the network, and sends the signal from the network back to the wireless LAN card. Because it plays a role of sending. In the case of wireless LAN, the data transmission rate is 5 Mbps, which is 5 million individuals per second, but the response radius is only about 200m, so it has to be installed in a limited area such as the center of a crowded city or a university library. . Therefore, you can't use it while moving like a cell phone, but you can use it while staying in a specific place like a cafe or library.

Next may be the WiBro system. WiBro stands for Wireless Broadband Internet, which refers to the high-speed portable Internet using the 2.3GHz frequency. It is a system that can service at a distance of about 5-6km from AP and the data transmission speed is about 1Mbps.

It may also be a WiMax system. WiMax is a system with a data rate of 70Mbps at a radio wave radius of about 30km to overcome the disadvantage that the existing Wi-Fi equipment has a response radius of only a few tens of meters, which requires a large number of apis and its limitation in availability.

It may also be a OnePhone system. OnePhone is a wired / wireless integrated service that sends and receives voice and data through a wired network within the AIP service area and a mobile communication network outside the AIP service area by embedding a technology such as Bluetooth capable of short-range wireless communication in a mobile phone terminal.

4 is a structural diagram of a combined terminal according to an embodiment of the present invention. Referring to FIG. 4, the combined terminal 400 includes a mobile communication modem 402, a wireless connection modem 404, a GPS receiving module 406, an AP information storage unit 408, a display unit 410, and a modem control unit 412. It is composed of

The mobile communication modem 402 communicates with the mobile communication base station 102 at all times. And receives a message transmitted by the mobile communication base station 102 within the service coverage of the mobile communication base station 102.

The modem 404 for wireless access is a modem that is selected by the holder of the combined terminal 400 to communicate with the AP 100. If the holder confirms the AP location information and the AP system information and the coupling terminal 400 is within the service coverage of the AP 100 and is a system supported by the coupling terminal 400, a modem for wireless access for high-speed data transmission ( 404 is turned on.

The GPS reception module 406 is for obtaining location information indicating the location of the coupling terminal 400. Referring to FIG. 3B, the GPS receiving module 406 receives a satellite signal from the satellite and transmits it to the mobile communication base station 102. The mobile communication base station 102 accurately detects the position of the combined terminal 400 based on the satellite signal received from the combined terminal 400 and transmits the position information back to the combined terminal 400.

The ap information storage unit 408 is a part for storing ap location information and ap system information received from the mobile communication base station 102 through the mobile communication modem 402.

The display unit 410 is a part for displaying the AP location information and the AP system information on the coupling terminal 400. The information is provided with information from the AP information storage unit 408.

The modem controller 412 controls the on-off of the mobile communication modem 402 and the wireless connection modem 404. In the combined terminal 400, when the holder wants to turn on the wireless connection modem 404 through the input of a button or the selection of a menu, the mobile communication modem 402 is turned off. The modem 404 is turned on.

In addition, as a result of confirming the AP location information, when the coupling terminal 400 is not currently located within the service coverage of the AP 100, the modem controller 412 forcibly prevents the wireless connection modem 404 from being turned on. In the combined terminal 400, power consumption caused by the on-line modem 404 being turned on may be prevented.

In addition, the combined terminal may select a modem for wireless connection or a modem for mobile communication through the input of a button or selection of a menu by a user interface. Accordingly, the holder of the combined terminal may check the AP location information and the AP system information displayed on the screen, and may arbitrarily turn on the modem for wireless access when the current location of the combined terminal is within the service coverage of the serving AP. In addition, when the combined terminal checks the AP location information and the AP system information and determines that the current location of the combined terminal is out of the service coverage of the AP, the combined terminal forces the OFF of the wireless connection modem to allow the holder of the combined terminal to connect wirelessly. You can disable your modem. In addition, the combined terminal may automatically operate the modem for wireless connection when the current position is within the service coverage of the AP.

5 is an exemplary diagram of a method for displaying ap location information according to an exemplary embodiment of the present invention. In the display unit 500 of the combined terminal, the location information of the AP, the AP service radius information, and the location of the combined terminal by GPS may be displayed on the electronic map. By displaying the location 502 of the AP and displaying the service radius from the AP in a dotted line and then displaying the location 504 of the current combined terminal holder on the same electronic map, the location 504 of the current combined terminal is the service of the AP. Allow the combined terminal holder to determine whether it is within coverage or not.

6 is an exemplary diagram of a method for displaying ap location information according to another exemplary embodiment of the present invention. If there are a plurality of ap's, the ap located at the closest distance from the current combined terminal is selected by comparing the ap location information and the location information of the combined terminal acquired by GPS technology. The location information of the selected AP and the distance from the current location of the combined terminal can be displayed. For example, when the combined terminal holder currently located in Gangnam Station searches for the location of the AP, the nearest AP is located in Starbucks, Gangnam Station. Distance: 100m "from the current location.

In addition, according to another preferred embodiment of the present invention, when there are a plurality of APs, all of the plurality of APs may be displayed. The position of a nearby AP is displayed on an electronic map around the current location of the coupled terminal, or it is displayed in a text form by numbering. Each location also shows what systems are supported by AP.

Referring to FIG. 7, in step S701, the AP 700 transmits the AP location information and the AP system information to the mobile communication base station 702. This is as described above with reference to FIG. 1. Thereafter, in step S702, the mobile communication base station 702 periodically transmits the AP location information and the AP system information to the combined terminal 704 even when no information request is received from the combined terminal 704. In operation S703, the combined terminal 703 compares the terminal location information and the API location information obtained using the GPS satellite signal received through the GPS reception module. In step S704, the comparison result is displayed on the combined terminal 704. Based on the location of the coupling terminal 704, it shows whether there is an AP 700 nearby, and if so, where is the location and how far the distance is. In step S705, the modem for wireless connection is operated according to the selection of the holder of the coupling terminal 704.

8 is an exemplary view showing the AP location information and the AP system information in the combined terminal according to another embodiment of the present invention. When the mobile communication base station 702 periodically transmits the AP location information and the AP system information, if it is determined that the combining terminal 704 is within the service coverage of the AP 700 as a result of the comparison in step S703, Mark it so that the holder can recognize it.
